Description

  The present invention relates to an ink supply container.

  2. Description of the Related Art Conventionally, as an example of an ink ejecting apparatus, an ink jet printer that can perform printing on a recording medium by ejecting ink from a recording head toward a recording medium such as recording paper is known. Some ink jet printers allow a user to replenish ink in an ink tank that stores ink supplied to a recording head. As a bottle (ink replenishment container) suitable for injecting ink into an ink tank, Patent Document 1 aims to diversify the bottle by providing a cap having a common shape for bottles having different ink storage capacities. It is disclosed.

  (1) A container that contains a viscous material or liquid in a container, a sealing material such as aluminum foil is formed at the container mouth, and is closed with a cap that is screwed onto the container mouth from above, Used in tube containers and squeeze bottles. In particular, in the case where the container contents are altered by contact with oxygen, a laminated sealing material mainly using an aluminum foil is used in order to prevent oxygen from entering the container. In this type of container, the cap is opened and the container is opened. At that time, the seal material is formed with a finger grip part, and the seal material is peeled off by pinching this knob part. Work is required.

  (2) As a known cap, Patent Document 2 includes an inner cap that is a lid main body and an overcap that is an upper lid, with respect to the inner plug, a main body side cylindrical portion, and a score at the tip thereof. The thing which provided the separation part currently provided continuously is disclosed. In this cap, the separation part separated from the main body side cylindrical part by screwing the overcap is held by an annular protrusion extending downward from the upper end inner wall of the overcap. Moreover, as a screwing structure of the cap, Patent Document 3 discloses a device in which a male screw screwed to the cap and a neck ring provided below the male screw are provided on the outer peripheral surface of the container mouth portion. Loosening is prevented by forming a plurality of protrusions that press and adhere to the inner surface of the cap at a plurality of locations on the ring.

(3) Conventionally, liquid dispensing containers in which a separable inner stopper is fitted to the container mouth and the container main body, the inner stopper, and the cap are separated and discarded after use are well known. There are various types of liquid dispensing containers that can separate the inner plugs. As typical examples, there are known liquid dispensing containers fitted with shoulder score type inner plugs as shown in FIG. Yes.
In FIG. 20, Aa is a container main body, Ba is an inner stopper, Ca is a cap, and an engagement protrusion 361 is provided on the outer periphery of the container mouth portion 360 of the container main body Aa. The fitting tube portion of the inner stopper Ba with respect to the container mouth portion 360 includes an inner tube 362, an outer tube 363, and a shoulder wall 364, and the inner tube 362 is fixed to the inner peripheral surface of the container mouth portion 360 with a certain amount of tightening. The outer cylinder 363 is fitted with a margin, and the inner surface of the outer cylinder 363 is fitted to the outer peripheral surface of the engagement protrusion 361 of the container mouth portion 360, and the lower end thereof is engaged with the lower surface of the engagement protrusion 361. A mating protrusion 365 is provided.
In order to enable separation of the inner stopper Ba, a cutout portion 367 is formed at one location of the outer cylinder 363 leaving a thin-cuttable connecting portion 366, and the portion corresponding to the cutout portion 367 is engaged. The joint protrusion 365 is omitted. The shoulder wall 364 has a cut hole 368 continuous with the notch 367 along the inner periphery of the outer cylinder 363, and a V-shaped cut groove is formed on the lower surface of the shoulder wall 364 following the cut hole 368. It is installed.

  (4) In recent years, with respect to synthetic resin containers for storing various liquids and other contents, the environmental burden has been reduced, and various thin-walled containers with a reduced amount of resin to be used are available. Has been developed. In addition, replenishing containers such as standing pouches are often used as containers for storing various contents. The replenishment container replenishes an expensive replenished container each time by replenishing the stored contents to a replenished container provided with a pump device on the lid or a dispensing part such as a dispensing spout. It can be used for a long time without being discarded.

  Further, in Patent Document 4, as a replenishment container for replenishing contents to a replenished container that does not have a dispensing part such as a dispensing spout, a mounting cylinder that is mounted at the mouth of the replenishing container and has a spout formed. And an operation member supported by the mounting cylinder so as to be slidable, and a pressing body disposed in the mounting cylinder, and the pressing body is slid by the mouth of the container to be replenished. A replenishment container is disclosed in which a sealing body of a sealing portion of a spout is pressed to open a spout.

  (5) Conventionally, thin-walled pouch containers formed of a film have been widely used as refill containers. As such a pouch container, Patent Document 5 discloses a standing pouch in which gusset portions are provided above and below the pouch container and a spout portion is provided at the top.

  (6) Conventionally, there is a liquid product in which a liquid is contained in a container. In these liquid products, a liquid pouring cap for pouring the liquid inside is attached to the mouth portion of the container. When such a liquid product is used, the container is usually pressed (squeezed) with the mouth portion of the container facing downward. Thereby, the liquid in a container will be poured out from the spout of a cap. However, conventional liquid pouring caps are not always easy to use, such as poor liquid drainage or internal liquid leaking out simply by directing the mouth of the container downward.

  Therefore, in Patent Document 6, a self-sealing cap (hereinafter referred to as a slit) is provided in which a valve body made of a flexible resin with a slit formed is provided on the cap body, and the slit is not opened unless a certain amount of pressure in the container is applied to the valve body. (Referred to as SS cap). In a liquid dispensing container equipped with such an SS cap, even if the container falls down or upside down, the liquid inside does not easily leak from the cap, so it is easier to use than the conventional one. It has become a thing. In addition, the conventional operation of opening and closing the cap can be omitted, which is very convenient. Other patent documents include Patent Documents 7, 8, 9, 10, and 11.

  (7) Plastic bottles that contain viscous contents have virgin seal performance to ensure the authenticity of the contents and liquid-cutting performance that makes liquid breakage good when the contents are poured out. It is desired. Currently, pull-ring-type inner stoppers used for viscous contents and the like generally use a cutting score as a virgin seal to ensure the validity of the contents (Patent Documents) 12, 13).

  (8) As a container pouring cap to be attached to the mouth and neck of a container, Patent Document 14 has a pouring cylinder for pouring the contents in the container, such as a screw or undercut on the mouth and neck of the container. A fitting cylinder fixedly held by the engaging means, a cap base that covers the surface of the fitting cylinder and is fixed to the mouth and neck of the container, and a bulge provided on the top of the cap base. The thing of the structure provided with the upper cover which seals the pouring path | route of this pouring pipe | tube by freely fitting is disclosed.

  (9) Conventionally, a pouring tap comprising a nozzle body attached to the mouth of the container and a lid body covering the nozzle body, and the nozzle body and the lid body are connected via a hinge. Is known. In conventional pouring taps, the lid is opened and the liquid on the opposite side of the hinge (the side facing the hinge) is tilted down to pour out the liquid, and then the liquid dripping from the pour cylinder at the upper peripheral edge of the nozzle body When the lid is closed, the liquid remaining on the peripheral edge of the upper surface of the nozzle body scatters due to the contact between the lower surface of the annular wall of the lid and the upper surface of the nozzle body. With respect to this problem, in Patent Document 15, a protrusion is formed on the upper surface of the pouring tool main body, thereby avoiding a direct collision between the lower surface of the cap and the upper surface of the pouring tool main body. A tool is disclosed.

(10) Conventionally, when a liquid content is poured out from a container, a cap provided with a pouring tube is attached to the container opening. As one form of such a pouring cap, a one-piece cap formed integrally with a cover cap via a hinge is used (see Patent Document 16).
A flexible plastic container is used as the container, and when pouring out the contents, squeeze the container while tilting it to push out the contents, and when pouring ends, stop the squeeze and return the container to its original position. return. Here, the content in the dispensing cylinder is pulled back into the container by its own weight or the suction force (suckback) when the container is restored from the squeezed state. And the liquid tends to remain in the dispensing cylinder, causing dripping and contamination of the dispensing cylinder.
As a technique for solving such a problem, in Patent Document 17, a curved surface composed of a reduced diameter portion that gradually decreases in diameter from the distal end of the extraction tube portion and an enlarged diameter portion that increases in diameter toward the proximal end is formed, In particular, an angle formed by a straight line connecting the outer peripheral front side edge of the connecting part connected to the container mouth part and the outer peripheral front side edge of the extraction cylinder part and a straight line orthogonal to the axis of the tip of the extraction cylinder part is 45 to 90 °. It is disclosed that.

JP 2014-88207 A International Publication No. 2007/126062 Japanese Patent Laid-Open No. 10-230950 JP 2012-012061 A Japanese Patent Laid-Open No. 10-329849 JP 11-278515 A JP-A-62-138595 JP-A-62-263297 Japanese Patent Laid-Open No. 61-296099 JP-A-60-243199 European Patent No. 0116422 JP 2003-72795 A Japanese Patent Laid-Open No. 2002-221607 JP-A-9-150858 Utility Model Registration No. 2534269 JP 2008-074468 A JP 2008-050011 A

(1) The sealing material is relatively tightly sealed at the container mouth, and since the seal itself is relatively small and the area of the knob portion is small, the work of peeling the sealing material is quite troublesome. If the peeling operation is not performed smoothly, the contents may spill or scatter and contaminate hands and clothes. In particular, when the container contents adhere to clothes, it is not easy to remove the seal material. The contents spill or splatter and dirty hands and clothes, resulting in discomfort to the user.
Thereby, after removing the cap from the container body, a container that does not require an operation of peeling off the seal at the container mouth has been desired.

(2) The cap described in Patent Document 2 can be easily opened just by screwing the overcap, and the separation part separated by the opening is held on the inner wall at the upper end of the overcap and the seal after opening Therefore, it is extremely easy to use, that is, easy to use. In this cap, a virgin ring is provided at the lower end of the overcap to prevent unintentional opening, but it is also conceivable to omit the virgin ring when downsizing and cost are prioritized. However, simply omitting the virgin ring tends to loosen the overcap when transporting the unsealed lidded container. Here, as described in Patent Document 3, for example, it may be possible to prevent loosening by forming a plurality of protrusions that are in close contact with the overcap on the container body side, but it is compared to opening and closing not only before opening but also after opening. Large force is required, and the operability may be reduced.
Accordingly, there has been a demand for a container having a cap that can be easily opened, can prevent unintentional opening, and can be easily attached and detached after opening.

(3) In the liquid dispensing container shown in FIG. 20, when the inner stopper Ba can be separated, the sealing property between the lower surface of the shoulder wall 364 and the mouth top surface 370 at the cut hole 368 and the cut groove portion. In addition, in the portion where the engagement protrusion 365 is removed, not only the sealing performance between the inner peripheral surface of the outer cylinder 363 and the outer periphery of the engagement protrusion 361 of the container mouth portion 360 is decreased, but also the shoulder The sealing property of the lower surface of the wall 364 is also lowered. If the inner peripheral edge of the mouth top surface 370 is scratched, the inner cylinder 362 is streaked when the inner stopper Ba is plugged, and a strip, that is, a fine line is formed between the inner cylinder 362 and the inner periphery of the container mouth 360. There was a problem that liquid leakage occurred when continuous holes were formed, and the sealing inside the container was impaired. In particular, when the streak was in a portion corresponding to the cut hole 368.
By the way, in the conventional container body Aa, the outer peripheral edge of the mouth top surface 370 of the container mouth part 360 and the connecting part 366 between the engaging protrusions 361 are rounded at the corner part 370a (FIG. 21) by a slight arc. It was attached or was almost not rounded. Therefore, when the container main body Aa is transported in the factory or when the container is packed and transported, the container main bodies Aa collide with each other, and the outer peripheral edge of the mouth top surface 370 of the container main body Aa is the top of the mouth of the other container main body Aa. The top surface 370 of the mouth of the container main body Aa is scratched by colliding with the inner peripheral edge or the outer peripheral edge of 370 to form the concave portions 371, 372 as shown in FIG. 21 or the streak 373. was there.
As described above, in particular, a scratch (concave portion 371) on the inner peripheral edge of the mouth top surface 370 streaks the inner tube 362 of the inner plug Ba and causes liquid leakage. In order to exclude the container main body Aa where the mouth top surface 370 of the container mouth part 360 has been damaged, an inspection is also performed before filling the content liquid, but there is a problem that the cost for the inspection is high. It was.
Thus, in the liquid dispensing container fitted with a separable inner stopper or hinge cap, the container body collides with each other during transportation of the molded container body or during packaging transportation, so that the top surface of the mouth of the container body Therefore, there has been a demand for a container that does not leak and prevents the inner plug or the fitting portion of the inner tube of the hinge cap from forming a streak at the time of stoppering.

(4) The conventional standing pouch is formed of a soft packaging material that is rich in flexibility and flexibility, and the container is likely to be deformed and unstable in a replenishment operation. On the other hand, in the replenishing container of Patent Document 4, since the liquid flowing from the replenishing container toward the replenished container flows through substantially the entire area in the mounting cylinder when the spout is opened, the liquid flowing into the replenished container The internal air is not released sufficiently due to the inflow, and it takes time for replenishment, or the liquid adhering to the vicinity of the mouth of the replenished container is pushed back to the air discharged from the replenished container, and the gap between the containers There is a risk of inconvenience such as leakage.
Accordingly, there has been a demand for a container that can efficiently replenish the contents while efficiently discharging the internal air accompanying the inflow of the liquid into the replenished container and preventing the liquid from overflowing. .

(5) Since the conventional pouch container is relatively poor in shape retention, the pouch container cannot be held in a stable shape with respect to the refill bottle at the time of refilling. There was a problem that refilling was difficult.
Accordingly, a container that can easily refill the contents in the refill container into the refill bottle has been desired.

  (6) The SS cap uses a flexible valve body in order to improve the liquid discharging performance (for example, controllability and ease of extrusion). For this reason, for example, when the container is shaken or overturned, there is a problem that the valve body is opened momentarily due to the impact, and the liquid inside is ejected.

  In order to solve this problem, Patent Document 6 provides a shielding member that is positioned on the container side of the valve body on the liquid dispensing path and has an opening area smaller than the opening area of the valve body base. Is disclosed. When such a shielding member is provided, the impact of the liquid toward the valve body is limited when the container falls, and the contact with the valve body is softened, so that the unintentional opening of the valve body can be prevented. .

However, in addition to preventing inadvertent opening of the valve body, further improvement is desired in order to reliably prevent liquid leakage from the valve body. In particular, a container containing a two-layer separated liquid composition containing a two-layer separated liquid composition is used as a container that is shaken. In this two-layer separated liquid composition, components having different specific gravity are separated into two upper and lower layers when stationary, and it is necessary to shake the container to mix the two layers during use. If this is the case, further measures against liquid leakage are required.
Accordingly, there has been a demand for a container that can reliably prevent the content liquid from jumping out or leaking out even when the container is used while being shaken.

  (7) The score requires a pull ring for tearing it open, and a spout is required to pour out the contents from where the pull ring is accommodated and a space for inserting a finger is required. Become bigger. The flow rate of the content liquid is regulated to some extent depending on the size and shape of the spout, but especially when the content liquid is a high-viscosity content liquid, the liquid breakage is poor and the return liquid after pouring remains in the dispensing part. As a result, the area around the pouring part is contaminated, and the liquid content may sag outside the pouring hole, and the pouring amount tends to become unstable.

In order to solve these problems, when the spout of the inner stopper is narrowed and the container is returned to its original state from the squeeze state, negative pressure due to suck back is applied to the spout to improve the liquid drainage performance. An improved sackback plug has been developed that sucks back the remaining liquid in the spout into the container. However, this sackback plug has a narrow spout, so there is enough space to place the pull ring. However, there is a problem that the number of parts increases to provide a virgin seal.
As a result, it has virgin sealing performance, the return of the remaining liquid after pouring into the nozzle is good, the liquid breakage is good, there is no contamination around the pouring part, and the content liquid is outside the spout. There has been a demand for a container having an inner stopper that does not sag and has a stable dispensing amount of the content liquid.

(8) In this type of conventional pouring cap, the content may sag (drip) along the outer surface of the pouring cylinder when the content is poured. When it adheres to the fitting part and is dried and solidified, slipping on the surface of the fitting part becomes worse, and the upper lid cannot be opened unless a force larger than usual is applied.
Accordingly, there has been a demand for a container having a cap that can smoothly open the lid even when the contents adhere, dry, and solidify due to dripping.

(9) In the pouring tool described in Patent Document 15, a protrusion is formed on the upper surface of the pouring tool body to prevent the liquid from scattering, but there is no liquid between adjacent protrusions on the upper surface of the pouring tool body. In particular, there is a problem that the liquid remaining between these protrusions leaks out when the container is tilted for the purpose of pouring the content liquid.
As a result, the content liquid dripping from the dispensing cylinder is surely removed to prevent the liquid from splashing when the lid is closed, and it is also possible to prevent dripping or leakage due to the content liquid once removed. A container having a proper discharge tap has been desired.

(10) In Patent Document 17, the extraction cylinder part must be very tall, or it must have a special shape that shifts the base line and tip axis of the extraction cylinder part, which is extremely different from the conventional one. In addition to the impression of appearance, it also increases the cost.
As a result, even when high-viscosity content liquid is dispensed, the content liquid does not remain around the spout and in the dispensing cylinder, preventing dripping and contamination of the dispensing cylinder, and the appearance remains the same as before And a cheap container with a dispensing cap has been desired.

  The present invention has been made to solve any one of the above-mentioned problems, and prevents ink from jumping out and leaking due to an unexpected operation of the ink supply container, and injecting ink from the ink supply container into the ink tank. An ink replenishing container that can prevent problems when injecting ink, including prevention of dripping and leakage during replenishment, and more efficient release of internal air in the ink tank during injection The purpose is to provide.

Since the slit connected to the storage space defined between the two is provided, the ink that flows out when the ink is dispensed flows into the storage space through the slit and is stored. Since the storage space is connected to the outside only by the slit, the ink once stored in the storage space is difficult to leak to the outside. Therefore, the ink dripping from the dispensing cylinder can be reliably removed to prevent the ink from scattering when the lid is closed, and it is possible to prevent dripping or leakage of the ink once removed.

  Application Example 11 An ink supply container according to this application example includes a container main body and a cap attached to the opening of the container main body, and the cap includes a dispensing cylinder attached to the opening of the container main body. A main body and a lid connected to the cap main body through a hinge so as to be openable and closable, and the pouring cylinder is provided to be shifted in the opposite direction of the hinge, and the pouring outlet of the pouring cylinder and the container side opening The communication hole is characterized by including a straight portion and a diameter-expanding portion that gradually increases in diameter from the container-side end of the straight portion toward the container-side opening.

  According to the ink supply container of this application example, even when high-viscosity ink is poured out, the ink does not remain around the spout or in the pour cylinder, thereby preventing dripping or contamination of the pour cylinder. it can. Further, it is possible to provide an ink supply container having an inexpensive cap with an appearance that does not change from the conventional one.

The oil-based ink may be either one having a configuration in which a solute such as a dye is dissolved in an oil-based solvent or one having a configuration in which a dispersoid such as a pigment is dispersed in an oil-based dispersion medium.

  In this embodiment, an ink supply container is used for injecting ink into the ink tank 9. Hereinafter, various embodiments of the ink supply container will be described.

[First Embodiment]
Hereinafter, the ink supply container 15 according to the present embodiment will be described with reference to the drawings. In the drawings, the same reference numerals represent the same or equivalent components.

  2 and 3 are partial cross-sectional views of the ink supply container 15 according to the first embodiment. Specifically, FIG. 2 is a cross-sectional view showing a state before the cap is opened in the ink supply container 15, and FIG. 3 is a cross-sectional view showing a state after the cap is opened. FIG. 4 is a cross-sectional view showing an example of the sealing material 104 used in the sealing structure. FIG. 5 is a cross-sectional view showing another example of the sealing material used in the sealing structure.

  In the present embodiment, the ink supply container 15 is configured as a tube container. As shown in FIG. 2, the ink supply container 15 is formed on the outer periphery of the container mouth portion 105 so as to cover the seal material 104 and the sealing material 104 that seals the container mouth portion 105. The cap 103 is screwed onto the screwed portion 106.

  An important feature of the sealing structure of the present invention is that the outer layer 104a of the sealing material 104 is strongly bonded to the top plate inner surface 103a of the cap 103, and the inner layer 104c of the sealing material 104 is weakly bonded to the container mouth portion 105. It is in. In the present invention, the expressions “strong adhesion” and “weak adhesion” do not mean numerical values of the adhesion strength, and the adhesion strength of the top plate inner surface 103a / outer layer 104a is the adhesion strength between the inner layer 104c / the container mouth portion 105. Means greater than. With this configuration, when the cap is opened, the seal with the inner layer 104c / container mouth portion 105 is peeled off, and the sealing material 104 remains bonded to the top plate inner surface 103a. Is done.

  Therefore, according to the seal of the present invention, the troublesome operation of peeling the sealing material 104 from the container mouth portion 105 with the fingertip after the cap is opened can be completely eliminated. In the sealing material 104 of the present embodiment, a synthetic resin coating layer is formed on both the inner and outer surfaces of the aluminum foil constituting the intermediate layer 104b. The synthetic resin coating layers formed on both the inner and outer surfaces of the aluminum foil are closely related to the type of resin constituting the cap 103 and the container body 102, and the cap 103 and the outer layer 104a are made of the same resin. It is necessary that the inner layer 104c and the container main body 102 be a combination of resins that do not completely weld even when subjected to high-frequency welding, but bring about a pseudo-adhered state.

  For example, as a general tube container, when the cap 103 is formed of polypropylene resin and the container body 102 is formed of polyethylene resin, the outer layer 104a, that is, the side in contact with the top plate inner surface 103a is made of polypropylene. A resin layer, particularly an unstretched film layer of polypropylene is preferably used. A peelable resin layer made of an unstretched film of a mixed resin of a polypropylene resin and a polyethylene resin is preferably used on the inner layer 104c, that is, the side in contact with the container mouth portion 105.

  The sealing material 104 of the present embodiment is a peelable in which the intermediate layer 104b is made of an aluminum foil, the outer layer 104a is a polypropylene-based unstretched film layer, and the inner layer 104c is a non-stretched film of a mixed resin of polypropylene-based resin and polyethylene-based resin. It is a laminated sheet formed by laminating resin layers.

  When this peelable layer is composed of a blend of polypropylene and polyethylene, the blend ratio (weight ratio) is polypropylene 90 to 10 and polyethylene 10 to 90, and the range of polypropylene 70 to 30 and polyethylene 30 to 70 is particularly preferable. It is.

  When acidic ink is used, the component acid may contact and react with the aluminum foil via the inner layer 104c, and the aluminum foil may be corroded. When the aluminum foil corrodes, hydrogen is generated. This causes hydrogen to enter the container and the container swells, not only deteriorating the commercial value but also causing the ink to scatter due to bursting.

  For these reasons, when an acid is included as an ink component, the coating of the peelable resin layer constituting the inner layer 104c on the aluminum foil constituting the intermediate layer 104b is in the middle, such as a biaxially stretched polyester film. It is desirable to carry out through the polyester resin layer 104d.

  The configuration of the container main body 102 of this embodiment is as follows: the outer layer of the olefin resin / the gas (air or oxygen) barrier resin layer / the cyclic olefin copolymer layer / the inner layer of the olefin resin from the outside to the inside. It has a configuration. In this case, the gas barrier resin layer and the cyclic olefin copolymer layer may be replaced with each other, and from the outside to the inside, the olefin resin outer layer / cyclic olefin copolymer layer / gas (air or oxygen). The layer structure of barrier resin layer / olefin resin inner layer may be used. Further, an oxygen-absorbing resin layer may be included between the cyclic olefin copolymer layer and the gas barrier resin layer. These layers are thermally bonded when there is thermal adhesiveness between the respective layers, and when there is no such layer, an adhesive layer is provided between the respective layers and integrated.

  Examples of the olefin-based resin outer layer and inner layer include low / medium / high-density polyethylene, linear low-density polyethylene, isotactic polypropylene, syndiotactic polypropylene, ethylene-propylene copolymer, polybutene-1, and poly-4. -Methyl-1-pentene, ethylene-butene-1 copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 copolymer, ethylene-vinyl acetate copolymer, ion-crosslinked olefin copolymer (Ionomer), ethylene-acrylic acid ester copolymer, and the like. These may be used alone or in a blend of two or more.

  The cyclic olefin copolymer layer serves to prevent a decrease in the barrier property of oxygen in the air in the gas barrier resin layer due to moisture, and the amorphous or low crystalline copolymer of olefin and cyclic olefin. Combined (COC) is mentioned. Ethylene is preferable as the olefin, but α having 3 to 20 carbon atoms such as propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 3-methyl 1-pentene, 1-decene, etc. -Olefin is used alone or in combination with ethylene. On the other hand, the cyclic olefin is an alicyclic hydrocarbon compound having an ethylenically unsaturated bond and a bicyclo ring, particularly, a hydrocarbon compound having a bicyclo [2,2,1] hept-2-ene skeleton.

  For the gas (oxygen) barrier resin layer, a thermoplastic resin having a low gas (air or oxygen) permeability coefficient and hygroscopicity is used. For example, the above-described ethylene-vinyl alcohol copolymer is optimal, but is not limited thereto, and is not limited to nylon 6, nylon 6/6, nylon 6/6/6 copolymer, metaxylylene azimuth. Polyamides such as Pamide, Nylon 6,10, Nylon 11, Nylon 12, Nylon 13, etc. are also used.

  For the oxygen-absorbing resin layer, a resin composition of an oxidizing resin and a transition metal catalyst or a resin composition of a thermoplastic resin and an oxygen absorbent is used. Here, the oxidizing resin is a resin that is oxidized by oxygen in the air by the action of the transition metal catalyst. For example, the main chain includes at least one functional group selected from the group consisting of a carboxylic acid group, a carboxylic anhydride group, a carboxylic acid ester group, a carboxylic acid amide group, and a carbonyl group. A resin containing a group, a polyamide resin, an ethylenically unsaturated group-containing polymer, or the like is used. The transition metal catalyst serves as a catalyst for the oxidation reaction of the oxidizing resin, and is an organic acid salt or organic complex salt of a transition metal.

  Examples thereof include iron, cobalt, nickel, copper, silver, tin, titanium, zirconium, vanadium, chromium, manganese, etc. Among these, cobalt is particularly preferable because of its high oxygen absorption rate. Further, as the oxygen absorbent, almost all conventional oxygen absorbents can be used, but those which are reducible and substantially insoluble in water are preferable, and reductive iron, reducible zinc, reductive tin powder, oxidized second The main component is a single or a combination of ferrous iron, tribasic iron oxide, iron carbide, silicon iron, iron carbonyl, iron hydroxide and the like. Further, a polymer compound having a polyhydric phenol in the skeleton, for example, a polyphenol-containing phenol-aldehyde resin can be used.

  The container mouth portion 105 of the ink supply container 15 is engraved with a thread as a screwing portion 106 on the outer peripheral surface thereof, and corresponds to the inner peripheral surface of the inner cylinder 108 of the cap 103 corresponding to the screwing portion 106. Are engraved with a thread as the threaded portion 107. Then, the cap 103 can be screwed into the container mouth portion 105 so as to be screwed.

  And as mentioned above, the front-end | tip of the container opening part 105 is sealed by the sealing material 104 containing metal foil. The ink is filled from the bottom of the container (not shown), and finally the container bottom is heat-sealed, so that the entire interior of the container body 102 has a gas barrier property, and air (oxygen) enters the interior of the container body 102. No contact with ink. In order to improve the antioxidation performance of the ink, it is preferable to provide a check valve (not shown) in the container opening 105 so that air does not enter the interior of the container body 102.

  In this embodiment, the cap 103 has a double cylinder shape of an inner cylinder 108 and an outer cylinder 109. Further, a screwing portion 107 (thread) is formed on the inner peripheral surface of the inner cylinder 108. The container mouth portion 105 can be detachably screwed. Since the material constituting the cap 103 and the resin constituting the coating layer constituting the outer layer 104a must be heat-fusible with each other, it is necessary that they be the same type of resin. It is made of polypropylene resin.

  The outer layer 104a and the inner layer 104c constituting the sealing material 104 are separately coated. As the laminate between the outer layer 104a and the intermediate layer 104b (aluminum foil), an extrusion laminate using a maleic anhydride-modified polypropylene adhesive is suitable. The laminate of the intermediate layer 104b (aluminum foil) and the inner layer 104c (peelable resin layer), or the intermediate layer 104b (aluminum foil) and the polyester resin layer 104d / inner layer 104c (peelable resin layer) is a urethane two-component curable adhesive. It is preferably performed by dry lamination using an agent.

  The sealing material 104 formed in this way only needs to be large enough to cover and seal at least the outer diameter of the container mouth 105, and the shape thereof is usually matched to the shape of the container mouth 105. It is formed in a substantially circular shape. Therefore, unlike the conventional sealing material, it is not necessary to have a shape having a knob portion for peeling, and since it is simply cut into a circle, it is easy to manufacture and saves material.

  In a state where the sealing material 104 is disposed in the cap mouth portion, the cap 103 is screwed onto the screwing portion 106 (screw) of the container mouth portion 105 so as to cover the sealing portion, and high frequency induction is performed from the top plate outer surface 103b of the cap 103. Heat. As a result, since the inner surface of the cap 103 and the outer layer 104a are both made of polypropylene resin, they are heat-sealed to form a strong bond. On the other hand, the inner layer 104c and the container mouth 105 are bonded to each other because the inner layer 104c is a blend of polyethylene and polypropylene (blend ratio = 30: 70) and the container body 102 is formed of polyethylene. However, the adhesion state is weak adhesion. The pseudo-adhesion refers to a state where the seal strength is sufficient to fulfill the purpose of the seal and is detachably bonded.

  In the present embodiment, as the most preferable example, both the cap 103 and the outer layer 104a of the sealing material 104 are made of polypropylene. It is desirable that the cap 103 and the outer layer 104a of the sealing material 104 are made of the same resin, and both of them must be polypropylene if a strong adhesive state can be obtained. is not. Similarly, the inner layer 104c of the sealing material 104 and the container mouth portion 105 are pseudo-bonded, but the bonding state may be weakly bonded, and depending on the material constituting the container body 102, the sealing is performed. The resin of the inner layer 104c of the material 104 may be adopted.

  In addition, the sealing material 104 of this embodiment is configured to have a certain thickness, and in a state where the sealing material 104 is disposed in the cap mouth portion, the cap 103 is disposed on the container mouth portion 105 so as to cover the sealing portion. When screwed into the threaded portion 106 (thread), the seal material 104 is crushed by the container mouth portion 105 and the top plate inner surface 103a of the cap 103, and the seal material 104 is deformed, so that the seal can be taken. . In this state, the sealing performance is further secured by performing the above-described heat fusion by high-frequency induction heating or pseudo-adhesion.

According to the first embodiment described above, the following effects can be achieved.
According to the ink supply container 15 of the present embodiment, since the sealing material 104 that seals the container opening 105 is formed in a fused state on the cap 103 side, the sealing material 104 is opened together with the cap 103 and the container opening 105. Is peeled off. Therefore, unlike conventional containers with a sealing material, there is no need to bother to remove the sealing material after opening the cap, and ink spills or splatters due to unintentional movements, resulting in dirty hands and clothes. This can prevent the user from feeling uncomfortable. In addition, the sealing material 104 need only be cut in accordance with the shape of the container mouth portion 105, and it is not necessary to cut in consideration of the knob portion for peeling, so that it is easy to manufacture and saves material costs. Also become.

  Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the scope of the invention. A modification will be described below.

  In the ink replenishing container 15 of the first embodiment, the tip of the container opening 105 is sealed by the sealing material 104, the ink is filled from the bottom of the container, and finally the container bottom is sealed by heat sealing. ing. Here, when sealing, reduced pressure sealing may be performed by sealing in a reduced pressure space. Alternatively, after the ink is filled, the container main body 102 may be pressed and sealed in a state where the air inside the container main body 102 is minimized. By sealing in this way, the quality as deaerated ink can be maintained.

[Second Embodiment]
Hereinafter, the ink supply container 15A according to the present embodiment will be described with reference to the drawings.

  FIG. 6 is a cross-sectional view of an ink supply container 15A according to the second embodiment. FIG. 7 is a cross-sectional view showing a sealed state of the inner plug 202 by the cap 201. FIG. 8 is a cross-sectional view showing a first state in the procedure for opening the inner plug 202 by the cap 201. FIG. 9 is a cross-sectional view showing a second state in the procedure for opening the inner plug 202 by the cap 201. FIG. 10 is a cross-sectional view showing the state of the ink supply container 15A in FIG. FIG. 11 is a cross-sectional view showing the ink supply container 15A in a state where the cap 201 is opened and the overcap 203 is detached.

  As shown in FIG. 6, the cap 201 of the ink supply container 15A according to the present embodiment is a resin molded product attached to the mouth portion 230a of the container main body 230 of the ink supply container 15A, and the inner plug 202 that is a lid main body. And an overcap 203 as an upper lid. The ink supply container 15 </ b> A stores and stores ink by a cap 201 and a container body 230 to which the cap 201 is attached. For simplification, only the right half of the cap 201 is shown in a cross-sectional view, but the left half with the rotation axis AX that is the central axis has the same structure as the right side.

  As shown in FIGS. 6 and 7, the inner plug 202 is an integral member in a state before opening the ink supply container 15 </ b> A, such as when the ink supply container 15 </ b> A is transported, and includes a separation unit 204, a fitting unit 205, The shape part 206 is provided. Here, the fitting portion 205 and the main body side cylindrical portion 206 constitute a main body portion 220 of the inner plug 202. The inner plug 202 and the container body 230 form a sealed space in which ink is sealed in an airtight or liquid tight manner. Among the inner plugs 202, the separation unit 204 is cut along the score 207 when the inner plug 202 is opened, that is, when the inner plug 202 is first opened, thereby forming an opening.

  The fitting portion 205 is a fitting member that fits the inner plug 202 into the mouth portion 230a of the container main body 230 by stoppering. The fitting part 205 is attached to the outer cylinder part 205a that is fixed in close contact with the peripheral wall of the mouth part 230a of the container body 230, the inner cylinder part 205b that is fixed in close contact with the inner wall of the mouth part 230a, and the mouth part 230a. It has a horizontal portion 205c that closely contacts and connects the outer cylinder portion 205a and the inner cylinder portion 205b. The main body-side cylindrical portion 206 is generally cylindrical, but has a lip 206a whose diameter increases upward at the upper end portion, and improves the drainage of liquid when the ink in the container main body 230 is poured out.

  The overcap 203 is an integral member made of resin, and includes a side wall 203a, an upper end wall 203b, and a seal portion 203d. The side wall 203a and the upper end wall 203b form a dome-like appearance and protect the inner plug 202 from an external environment such as dust and water. The side wall 203a has a female screw that is a screwing portion 211a, and is screwed around a rotation axis AX with a male screw that is a screwing portion 211b formed on the side surface of the container body 230. As a result, the overcap 203 can be opened and closed and can be attached to and detached from the container body 230. Further, the inner wall of the seal portion 203d is in close contact with the horizontal portion 205c of the fitting portion 205 at the time of closing after opening (see FIG. 9). As a result, the periphery of the main body side tubular portion 206 is kept liquid-tight during closing, and the overcap 203 can be plugged.

  In the above, in the cap 201, the separation portion 204 of the inner plug 202 has the separation portion side tubular portion 204b that is offset to the inner diameter side by the thickness of the main body side tubular portion 206 with respect to the main body side tubular portion 206. In addition, a ceiling wall 204c that closes the upper opening of the separation portion side cylindrical portion 204b is stretched. Further, a flange 204d extending outward in the radial direction is formed at the upper end of the separation portion side cylindrical portion 204b. Further, an annular locking portion 204e for locking the overcap 203 is formed on the front end side of the flange 204d. The locking portion 204e is provided with a cylindrical first side surface portion 204f extending in the axial direction of the rotation axis AX (see FIG. 7). Note that the lower end of the separation portion side cylindrical portion 204 b is connected to the upper end of the main body side cylindrical portion 206 by a thin score 207.

  Further, in the overcap 203, the upper end wall 203b is provided with an annular projecting portion 209 extending downward on the lower surface thereof, and a claw 209a for engaging with the flange 204d at the time of opening is formed at the lower end of the projecting portion 209. Has been. In other words, the upper end wall 203b functions as a holding portion that can hold the separated portion 204 after separation by including the annular or cylindrical protruding portion 209. Furthermore, in the upper end wall 203b that is a holding portion, an annular rotation suppressing portion 209b for suppressing rotation with respect to the inner cap 202 of the overcap 203 before opening is formed at the tip, that is, the lower end side of the protruding portion 209. . The rotation suppressing portion 209b is provided with a cylindrical second side surface portion 209c extending in the axial direction of the rotation axis AX. In a state where the overcap 203 exists at the reference position before the rotational operation of the screwing portion 211a, the second side surface portion 209c is locked to the separation portion 204 by contacting the first side surface portion 204f of the separation portion 204. .

  The rotation suppression force of the overcap 203 due to the rotation suppression unit 209b being locked to the separation unit 204 is determined assuming a rotational force that is erroneously applied to the overcap 203 when the ink supply container 15A is transported. Yes. That is, the force that locks the rotation suppression unit 209b in the separation unit 204 generates a suppression force that does not cause the overcap 203 to rotate and loosen when the ink supply container 15A before opening is transported. Thus, the degree of fitting of the second side surface portion 209c is appropriately determined, and the rotation suppressing portion 209b at the reference position can suppress the rotation of the overcap 203 with respect to the inner cap 202 with a certain amount of force. This prevents unintentional opening of the cap 201 in a state where the separation portion 204 is connected to the inner plug 202 before opening the overcap 203.

  The cap 201 configured in this manner is rotated by applying a force that exceeds the force of suppressing the rotation of the overcap 203 by the locking of the rotation suppressing unit 209b in the separation unit 204, and the ink supply container 15A is opened. be able to. That is, when the overcap 203 is rotated with such a force, the separation portion 204 can be separated from the main body side tubular portion 206 by the upper end wall 203b of the overcap 203 that can press the separation portion 204 of the inner plug 202. .

  At this time, the separating portion 204 can be held on the overcap 203 side by the protruding portion 209 formed on the overcap 203 and the flange 204d formed on the separating portion 204, and the opening is performed while the overcap 203 is rotated. Accordingly, the separation portion 204 can be separated from the inner plug 202 to form an opening. On the other hand, the locking of the rotation suppressing unit 209b in the separation unit 204 described above is released during the opening operation. Furthermore, the separation unit 204 remains held on the overcap 203 side.

  Hereinafter, the opening operation of the ink supply container 15A by the cap 201 will be described with reference to FIGS.

  First, as shown in FIG. 7, the separation part 204 of the inner plug 202 is separated from the main body part 220 from the state in which the overcap 203 is at the reference position before the rotational operation of the screwing part 211 a and the cap 201 is sealed. For this purpose, the overcap 203 is rotated in the tightening direction, that is, clockwise. At this time, as described above, a force greater than the force applied to the overcap 203 is required when the normal ink supply container 15A is transported.

  When the overcap 203 is rotated, as shown in FIG. 8, the protruding portion 209 is engaged with the flange 204d of the inner plug 202, and the claw 209a is engaged with the lower peripheral surface of the flange 204d. That is, the separation unit 204 is held on the overcap 203 side. At this time, the locking state of the rotation suppressing portion 209b by the locking portion 204e is released.

  Further, when the overcap 203 is tightened, the separation portion 204 of the inner plug 202 is pushed downward by the upper end wall 203 b of the overcap 203. Then, the score 207 is cut, and the separation unit 204 is inserted into the main body side tubular portion 206 of the main body 220 as shown in FIGS. 9 and 10. That is, the separation part 204 is separated from the main body part 220 and can be detached from the main body side cylindrical part 206 of the main body part 220.

  In this state, when the overcap 203 is rotated in the loosening direction, that is, counterclockwise, as shown in FIG. 11, the separation portion 204 is detached from the main body side cylindrical portion 206 of the inner plug 202 with the overcap 203. . As described above, the inner plug 202 is opened, and the ink in the container main body 230 can be poured out from the formed opening OP.

  Further, the overcap 203 is detachable from the container main body 230. At this time, since the locking of the rotation suppressing portion 209b in the separation portion 204 no longer exists, the overcap 203 is opened with a normal force without requiring a large force as in the case of the rotating operation at the time of opening.・ It can be closed. Further, the separation unit 204 functions as an inner seal plug that can close the opening OP after opening.

  As described above, in this embodiment, the upper end wall 203b of the overcap 203 serving as the holding portion is locked to the separation portion 204 at the reference position before the rotational operation of the screwing portion 211a, thereby Since it has the rotation suppression part 209b which suppresses rotation with respect to the inside plug 202, in the state which the isolation | separation part 204 is connected with the inside plug 202 which is the state before opening of the overcap 203, unintentional opening can be prevented. In addition, once opened, the separating portion 204 is separated from the inner plug 202 and engages with the upper end wall 203b, so that the locking of the rotation suppressing portion 209b to the separating portion 204 is released, and the inner cap 202 of the overcap 203 is released. The overcap 203 can be easily attached to and detached from the container main body 230.

  Further, since the separation unit 204 is cut off from the inner plug 202 in the opening operation with the cap 201, the cap 201 is opened with the rotation operation of the overcap 203 as an upper lid, that is, the inner plug 202 has a relatively simple structure. Can be opened, and the separated separation portion 204 is held by the overcap 203.

  Further, in this case, since the inner plug 202 does not use a pull ring, a situation in which the pull ring is cut at the weld portion that may be generated when the pull ring is opened and the opening cannot be prevented does not occur. Further, since the inner plug 202 is opened by the rotation operation of the overcap 203, it can be easily and reliably opened with a smaller force than when the pull cap is pulled to open. Furthermore, since the separation part 204 is integrated with the overcap 203 after the opening of the inner plug 202, it is not necessary to clean up as garbage after opening, so that handling is improved.

  In the present embodiment, the inner plug 202 is a plug-type composite cap, and the ink is sealed in an airtight or liquid-tight manner together with the container main body 230 by a stopper using the fitting portion 205. However, the ink can be sealed in an airtight or liquid-tight manner, for example, not only by plugging but also by sealing by screw type or welding.

  In the above-described embodiment, the inner plug 202 is illustrated in the case where the separation portion side tubular portion 204b is offset inward by the thickness of the main body side tubular portion 206 from the main body side tubular portion 206. However, the separation portion side cylindrical portion 204b may be offset outward from the main body side cylindrical portion 206 by the thickness of the main body side cylindrical portion 206.

  Moreover, in the said embodiment, the seal | sticker which is a cyclic | annular low protrusion can be provided in at least one of the outer peripheral surface of the isolation | separation part side cylindrical part 204b and the inner peripheral surface of the main body side cylindrical part 206. FIG. By providing such a seal, a reliable liquid-tight state can be secured between the separation portion side tubular portion 204b and the main body side tubular portion 206. That is, it is possible to reliably prevent liquid leakage upon repeated reuse after the first opening.

<First Modification>
Hereinafter, with reference to FIG. 12, the cap 251 which concerns on the 1st modification of 2nd Embodiment is demonstrated.
FIG. 12 is a cross-sectional view showing a cap 251 according to the first modification. FIG. 12 shows an enlarged part of the cap 251.

  The cap 251 according to this modification is the same as the cap 201 of FIGS. 6 to 11 except for the structure of the separating portion 254 of the inner plug 252 and the protruding portion 259 of the overcap 253. Therefore, illustration and description of the entire cap 251 are omitted.

As shown in FIG. 12, the cap 251 of this modification has a fitting structure in which the separating portion 254 and the protruding portion 259 are fitted. Hereinafter, the fitting structure will be described more specifically.
First, in the separation portion 254, the flange 254d that constitutes the ceiling wall 254c has a first fitting portion 254g having a concavo-convex shape in the first side surface portion 254f of the locking portion 254e that is the tip portion. As shown in FIG. 12, the first fitting portion 254g is convex toward the distal end side of the locking portion 254e, that is, toward the outside.

  On the other hand, the rotation suppression part 259b which comprises the front end side among the protrusion parts 259 has the 2nd fitting part 259d which has the uneven | corrugated shape corresponding to the 1st fitting part 254g in the 2nd side part 259c. ing. That is, the second fitting portion 259d is concave toward the inside in the second side surface portion 259c. By fitting the first fitting portion 254g and the second fitting portion 259d, rotation suppression of the overcap 253 is enhanced.

  As described above, in this modification, the cap 251 has a fitting structure including the first fitting portion 254g and the second fitting portion 259d in addition to the contact between the first side portion 254f and the second side portion 259c. The rotation of the overcap 253 during conveyance is suppressed. In this case, since the locking state by the locking part 254e and the rotation suppression part 259b can be adjusted by appropriately determining the degree of fitting, the rotation suppression of the overcap 253 by the rotation suppression part 259b is made more reliable. It becomes possible. In addition, although the uneven | corrugated shape in FIG. 12 shall have one convex shape in the latching | locking part 254e side, and one concave shape in the protrusion part 259 side, it is not restricted to this but various shapes are applicable.

<Second Modification>
Hereinafter, with reference to FIG. 13, the cap 261 which concerns on the 2nd modification of 2nd Embodiment is demonstrated.
FIG. 13 is a cross-sectional view showing a cap 261 according to a second modification.

  The cap 261 according to the present modification is a modification of the cap 201 of the second embodiment shown in FIG. 6, and the structure other than the structure of the separation part 264 of the inner plug 262 and the protrusion part 269 of the overcap 263 will be described. Omitted.

  As shown in FIG. 13, in the separation portion 264, in the flange 264d that constitutes the ceiling wall 264c, the locking portion 264e that is the tip is formed inward in the radial direction. Specifically, the locking portion 264e extends vertically upward from the flat portion FT of the flange 264d, and further extends from the tip of the connecting portion CP to the inside, that is, toward the rotation axis AX, and contacts the protruding portion 269. And a contact portion AP including a first side surface portion 264f that is in contact with the contact portion AP. That is, in this case, the first side surface portion 264f faces the inner side, that is, the rotation axis AX side, unlike the first side surface portion 204f in FIG.

  The rotation suppressing portion 269b of the protruding portion 269 has a structure in which the second side surface portion 269c faces the outside, that is, the side opposite to the rotation axis AX side, according to the structure of the locking portion 264e described above. Note that the claw 269a of the protruding portion 209 is formed on the same surface as the second side surface portion 269c. Thereby, in the opening operation, the contact portion AP of the locking portion 264e is locked to the claw 269a, and after the opening, the separation portion 264 is separated from the inner plug 262 and engages with the upper end wall 263b. It will be a thing.

  As described above, also in this modified example, since the rotation suppressing portion 269b that suppresses the rotation of the overcap 263 with respect to the inner plug 262 is provided, the separation portion 264 is connected to the inner plug 262 before the overcap 263 is opened. In the state, unintentional opening can be prevented.

<Third Modification>
Hereinafter, with reference to FIG. 14A, FIG. 14B, and FIG. 14C, the cap 271 which concerns on the 3rd modification of 2nd Embodiment is demonstrated.

  The cap 271 according to this modification is a modification of the cap 201 of the second embodiment shown in FIG. 6, and the structure other than the structure of the separation portion 274 is the same as the cap 201 of FIG. The illustration and description of this structure are omitted.

  FIG. 14A is a schematic diagram showing a cap 271 according to a third modification. FIG. 14A corresponds to FIG. 7 that shows a state cut along the XX section perpendicular to the rotation axis AX. 7 shows only the right half of the XX cross section, but FIG. 14A shows the state including the left half.

  As shown in FIG. 14A, the outer peripheral contour of the flange 274d of the separation portion 274 constituting the cap 271 is a polygon. That is, the first side surface portion 274f that is the outer edge of the locking portion 274e is a polygon. Here, as an example, the first side surface portion 274f is assumed to be a regular octagon. In contrast, the second side surface portion 209c of the rotation suppressing portion 209b is assumed to be circular as in the case of FIG. Here, it is assumed that the diameter of the first side surface portion 274f and the diameter of the second side surface portion 209c are substantially the same.

  Accordingly, as shown in FIG. 14A, the first side surface portion 274f and the second side surface portion 209c are intermittently brought into contact with each other, and the rotation suppressing portion 209b is locked to the separation portion 274. In this case, the outer peripheral shape of the first side surface portion 274f and the inner peripheral shape of the second side surface portion 209c are different from each other, but can be prevented from rotating by the screwing portion 211a. The diameter of the inner peripheral contour of the claw 209a for engaging with the separation part 274 is slightly smaller than the diameter of the first side surface part 274f, and after the opening operation, the separation part 274 is a protruding part. 209 is engaged.

  FIG. 14B is a schematic diagram illustrating another example of the cap 271 according to the third modification. As with the cap 281 shown in FIG. 14B, contrary to the above case, the inner peripheral contour of the rotation suppressing portion 289 b of the protruding portion 289 may be a polygon. That is, the second side surface portion 289c that is the inner edge of the rotation suppressing portion 289b may be a polygon. Here, as an example, the second side surface portion 289c is assumed to be a regular octagon. In contrast, the first side surface portion 204f of the separation unit 204 is assumed to be circular as in the case of FIG. Here, it is assumed that the diameter of the second side surface portion 289c and the diameter of the first side surface portion 204f are substantially the same.

  Accordingly, as shown in FIG. 14B, the first side surface portion 204f and the second side surface portion 289c are intermittently brought into contact with each other, and the rotation suppressing portion 289b is locked to the separation portion 204. In this case, the outer peripheral shape of the first side surface portion 204f and the inner peripheral shape of the second side surface portion 289c are different from each other, but can be prevented from rotating by the screwing portion 211a. The diameter of the inner peripheral contour of the claw 289a for engaging with the separation portion 204 is slightly smaller than the diameter of the first side surface portion 204f, and the separation portion 204 is a protruding portion after the opening operation. 289 is engaged.

  FIG. 14C is a schematic diagram illustrating another example of the cap 271 according to the third modification. Like the cap 291 shown in FIG. 14C, both the separating portion 294 and the protruding portion 299 may have a regular octagonal cross section. In this case, since both are polygonal and rotation is restricted at a constant angular period, the force for suppressing the rotation operation by the screwing portion 211a can be further increased, and the locking prevention is made more reliable. Can do.

  In the above description, as an example, the separation portion and the rotation suppression portion are described as having a regular octagonal cross section, but the cross sectional shape may be other polygons. In addition, various non-circular shapes may be used.

  In the ink supply container 15A of the second embodiment described above, when sealing the ink by installing the inner plug 202 in close contact with the mouth portion 230a of the container body 230 into which the ink has been injected, the ink is sealed in the decompression space. It is good to perform pressure reduction sealing by stopping. By sealing in this way, the quality as deaerated ink can be maintained. Moreover, when the container main body 230 has elasticity, in the sealing, the container main body 230 may be pressed and sealed in a state in which the air inside the container main body 230 is eliminated as much as possible. By sealing in this way, the quality as deaerated ink can be similarly maintained.

The shoulder wall 335 and the side tube 336 constitute a cover tube 332 for the fitting tube portion 310 of the inner plug B.

  When the cap C is screwed and fastened to the inner plug B, the outer periphery of the sealing ring 333 is fitted to the inner periphery of the pouring cylinder 311 to seal the pouring cylinder 311, and the covering cylinder 332 is fitted to the inner plug B. It fits so that the outer peripheral surface of the shoulder wall 315 of the combined cylinder part 310 and the outer cylinder 313 may be covered.

Next, the formation and usage of the ink supply container 15B will be briefly described.
The ink supply container 15B of the present invention is molded by blow molding, and is transported to the filling process after molding, or packed and transported to the filling factory. After the ink is filled, the inner plug B fitted with the cap C is fitted into the container opening 301 by the stopper, and then packed and transported as an ink supply container 15B.

  When the ink supply container 15B is used, the extraction hole can be opened by pulling up the finger ring 329 as in the case of the conventional container, and the ink can be discharged. Further, when discarding the container after use, when the knob 321 of the outer cylinder 313 is pulled, the outer cylinder 313 is cut along the cutting groove 322 on the lower surface of the shoulder wall 315, and the inner plug B is easily unplugged from the container mouth 301. And can be disposed of separately.

Next, the effect based on the shape of the container mouth part 301 is demonstrated.
The container main body A collides with each other when the container main body A is transported in the factory after molding, or when packed and transported to the filling factory, and the top surface 306 of the container mouth 301 is formed. It happens to collide with each other.

  However, the outer peripheral edge of the top surface 306 of the container mouth portion 301 and the corner portion a of the engagement protrusion 304 are rounded by a large arc R to form a smooth curved surface 308. Thereby, even if the container mouth portion 301 of the container main body A collides, surface contact is made, and the top surface 306 of the container mouth portion 301 of the counterpart container main body A and the inner and outer peripheral edges thereof are not damaged. Accordingly, since the inner cylinder 314 of the inner plug B is not streaked due to scratches on the inner peripheral edge of the top surface 306, liquid leakage from between the inner cylinder 314 and the inner periphery of the container mouth portion 301 is prevented. Absent.

First, the container lid 519 is removed from the dispensing opening cylinder 518, and the opening 518A of the dispensing opening cylinder 518 is opened. Then, this ink supply container 15E is screwed into the female screw cylinder portion 512 and the mouth portion 521 until the surface 511a of the flange-like portion 511 contacts the opening end surface 521a of the mouth portion 521 in an airtight state, thereby supplying other ink. Connect to container 520. Accordingly, the inside of the container main body 501a and the inside of the other ink supply container 520 are communicated with each other through the opening 518A and the opening 521, and the ink in the container main body 501a is transferred to the other ink supply container 520.

  In the ink supply container 15E according to the present embodiment described above, when the ink is supplied into the other ink supply container 520, the female screw cylinder portion 512 and the mouth 521 of the other ink supply container 520 are engaged with each other and the injection is performed. Since the outlet opening cylinder portion 518 is inserted into the mouth portion 521, the ink supply container 15E can be stabilized without being staggered or tilted with respect to the other ink supply containers 520.

  Further, since the dispensing opening cylinder 518 and the female threaded cylinder 512 are erected from the surface of the container main body 501a, the female threaded cylinder 512 and the mouth 521 of another ink supply container 520 are connected. When engaged, the dispensing opening cylinder 518 can be inserted without interfering with the mouth 521.

  Further, the flange-like portion 511 positioned between the dispensing opening cylinder portion 518 and the female screw cylinder portion 512 is airtight with the opening end surface 521a of the mouth portion 521 when supplying ink into another ink supply container 520. For example, when the ink to be replenished is high-viscosity ink and the ink is replenished into another ink replenishing container 520, the flange-shaped portion 511 is opened to the opening end surface 521a of the mouth portion 521. The other ink supply container 520 is squeezed in a state of being in airtight contact with the air, and the air in the container is once allowed to flow into the ink supply container 15E, and then the other squeeze deformation is released. Highly efficient replenishment is realized when ink in the ink replenishing container 15E is sucked into another ink replenishing container 520 due to negative pressure in the ink replenishing container 520. Door can be.

  That is, when the other ink supply container 520 is squeezed and deformed in a state where the flange-like portion 511 is in airtight contact with the opening end surface 521a of the mouth portion 521, the air in the container may leak to the outside. Disappear. Therefore, when the squeeze deformation is performed as described above, all of the air pushed out from the other ink supply container 520 is caused to flow into the ink supply container 15E, while the other ink supply container 520 is released when the squeeze deformation is released. The negative suction force can be applied to the ink in the ink supply container 15E.

  In addition, when the ink supply container 15E is manufactured with a film using aluminum or the like, the permeability of gas such as water vapor can be lowered as compared with that made of resin. Can be maintained. Further, the ink whose viscosity and ink deaeration are maintained can be replenished to other ink replenishing containers and ink tanks.

Next, a modification of the present embodiment will be described with reference to FIG.

The mounting cylinder portion 514A is formed in a bottomed cylindrical shape including a peripheral wall 514a and a shielding wall 514b extending in a direction orthogonal to the peripheral wall 514a. In the central part of the shielding wall 514b, an extraction hole 514c for fitting the stopper 517 in a liquid-tight state is formed. Here, the space between the plug 517 and the dispensing opening cylinder 518 communicates with the inside of the ink supply container 15E.

  When the ink is supplied into the other ink supply container 520, the female screw cylinder 514 B and the other ink are in a state where the mounting cylinder 514 A is in contact with the inner peripheral surface 521 b of the other ink supply container 520. When the supply container 520 is relatively moved in the axial direction, the dispensing hole 514c is opened.

  In the present modification, a protrusion 518 b that protrudes radially inward is formed on the inner peripheral surface of the distal end of the dispensing opening cylinder 518. A support cylinder 516 is suspended from the shielding wall 514b so as to be positioned between the dispensing opening cylinder 518 and the plug 517. On the outer peripheral surface of the lower end of the support cylinder portion 516, a locking convex portion 516a that locks to the protruding portion 518b is formed.

  Next, a method of supplying ink from the ink supply container 15E configured as described above to another ink supply container 520 will be described.

  First, in a state where the plug 517 is liquid-tightly fitted into the outlet hole 514c of the shielding wall 514b of the engagement lid member 514, the mounting cylinder 514A is fitted to the inner peripheral surface 521b of the mouth of the other ink supply container 520. Combine. Next, the dispensing opening cylinder 518 and the other ink supply container 520 are rotated to move relative to each other in the axial direction, thereby opening the dispensing hole 514c, and at the peripheral wall 514a side of the air bleeding groove 515. The opening at is opened. As a result, the interior of the container body 501a communicates with the interior of the other ink supply container 520 between the stopper 517 and the dispensing opening cylinder 518 and through the dispensing hole 514c, and the other through the air vent groove 515. The inside and the outside of the ink supply container 520 are communicated.

  As described above, when the dispensing opening cylinder 518 is rotated with respect to the other ink supply container 520, the projection 518b comes into contact with the locking projection 516a. Movement to is regulated.

  In the ink supply container 15E according to this modification described above, the operational effects of the above-described embodiment are achieved, and the female screw cylinder 514B of the engagement lid member 514 is engaged with the mouth 521 of the other ink supply container 520. In addition, since the mounting cylinder 514A of the engagement lid member 514 is fitted to the inner peripheral surface 521b of the other ink supply container 520, the ink supply container 15E can be further stabilized.

  The present invention is not limited to the above-described embodiments and modifications, and various changes and improvements can be added to the above-described embodiments and modifications. Other modifications will be described below.

  (1) In the present modification shown in FIG. 33, the air vent groove 515 is formed on the outer peripheral surface of the mounting cylinder portion (peripheral wall 514a). However, the air vent groove 515 may not be formed.

  (2) In this embodiment and this modification, the opening 521 and the engagement tube portion of another ink supply container 520 are screwed together. However, the present invention is not limited to this. For example, a screw portion for screwing is formed. A plurality of annular protrusions are formed on the outer peripheral surface of the mouth portion so that undercut fitting is possible at a plurality of positions in the height direction. Various configurations such as a configuration in which a fitting projection that can be fitted to the annular projection is formed on the inner peripheral surface of the projection can be adopted.

  (3) In this embodiment and this modification, a pouch container is used as the ink supply container 15E, but a blow bottle, a tube container, or the like can also be used. At this time, the surface of the container main body 501a and a flange-like portion projecting radially outward from the lower end portion of the dispensing opening cylindrical portion are configured as the base portion 511.

  (4) In this embodiment, the internal thread cylinder portion 512 and the mouth portion 521 are screwed together to fix the ink supply container 15E and another ink supply container 520. However, it is not limited to this, and it may be fixed by engagement or fitting.

However, the present invention is not limited to this, and the ink tank 9E may be supplied with ink from the ink supply container 15E. In this case, as a premise, the ink tank 9 can be individually detached from the ink supply device 3 (FIG. 1). The ink tank 9 can be squeezed.

[Seventh Embodiment]
Hereinafter, the ink supply container 15F of the present embodiment will be described with reference to the drawings.

  FIG. 34 is a side view of the ink supply container 15F according to the seventh embodiment. FIG. 35 is an exploded perspective view of an SS cap (self-sealing cap) 601. FIG. 36 is a longitudinal sectional view of the SS cap 601. FIG. 37 is a plan view of the SS cap 601 as viewed from the distal end side.

  The ink supply container 15F of this embodiment includes, for example, an SS cap 601 as shown in FIGS. 34, 35, and 36, and a container body 602 to which the SS cap 601 is attached.

  The container main body 602 is a squeeze container that can be repeatedly pressed (squeezed), and is made of a relatively soft synthetic resin material such as polyethylene resin, polypropylene resin, or polyester resin formed into a bottle shape by blow molding. The body 602a that rises in a cylindrical shape from the bottom of the container body 602 has an elastic restoring force that can be repeatedly elastically deformed (squeezed). For example, an SS cap 601 is attached to the mouth portion 602b located on the upper portion of the trunk portion 602a by screwing. For this reason, a screw thread 602c for fixing a cap body 603 of an SS cap 601 described later by screwing is formed on the outer peripheral surface of the mouth portion 602b.

  The shape of the container body 602 is not particularly limited, but is preferably a shape that is easy to hold during use and that does not easily cause liquid leakage even when a load is applied. It is preferable to use the cylinder bottle. In addition, the thickness (resin amount) of the container body 602 affects the ease of pushing (hardness) during use, and therefore it is necessary to appropriately select the capacity and the resin amount of the container body 602.

  The SS cap 601 is attached to the mouth portion 602b of the container body 602, and dispenses ink contained in the container body 602. The SS cap 601 includes a cap body 603 fixed to the mouth portion 602b of the container body 602. ing. The cap body 603 is made of a plastic member that is formed in a substantially cylindrical shape so as to close the mouth portion 602b of the container body 602.

  In addition, a circular opening 603 a is provided at the tip of the cap body 603. A screw thread 603 b is formed on the inner peripheral surface of the cap body 603. The SS cap 601 is attached to the mouth portion 602b of the container main body 602 by screwing the screw thread 603b on the cap main body 603 side and the screw thread 602c on the container main body 602 side. The SS cap 601 is further provided with a plastic overcap 604 detachably provided on the cap body 603.

  Inside the cap body 603, there is a valve body 605 that opens and closes the slit 605 a according to the pressure in the container body 602 when the container body 602 is squeezed, and liquid leakage from the slit 605 a of the valve body 605. An impregnation member 606 for preventing and a shielding member 607 for adjusting the flow rate of ink flowing from the container main body 602 side toward the valve body 605 are arranged in this order from the front end side.

  The valve body 605 is made of a flexible elastic member such as silicon rubber or elastomer. Among these, it is particularly preferable to use silicon rubber that is easy to mold and difficult to tear. The valve body 605 includes a substantially circular ceiling portion 605b, a cylindrical skirt portion 605c that gradually decreases in diameter from the periphery of the ceiling portion 605b, and an outer edge from the edge of the skirt portion 605c. An annular flange portion 605d having an enlarged diameter is integrally formed with a cap shape. The slit 605a has a + -shaped cut as shown in FIG. 37, and is formed at the center of the ceiling portion 605b recessed inward.

  The valve body 605 is fitted inside the cap body 603 with the inside of the recess 605e formed of the ceiling portion 605b and the skirt portion 605c facing the container body 602 side. Accordingly, the slit 605a of the ceiling portion 605b is exposed to the outside from the opening 603a of the cap body 603.

  The valve body 605 is fixedly held in the cap body 603 by the flange portion 605d being pressed against the inner surface of the cap body 603 by a ring-shaped stopper 608 fitted inside the cap body 603. Note that an opening 608 a having substantially the same diameter as the recess 605 e of the valve body 605 is formed at the center of the stopper 608.

  The impregnating member 606 is made to absorb the outflow pressure (impact) of the ink flowing toward the valve body 605 by its elasticity, and the shock absorbing function prevents the outflow pressure of the ink from being directly applied to the valve body 605. And a liquid leakage prevention function that impregnates the ink and prevents liquid leakage from the slit 605a of the valve body 605.

  The impregnating member 606 can be impregnated with ink and does not obstruct ink ejection from the slit 605a of the valve body 605 and introduction of outside air when the container body 602 is squeezed, for example, sponge , Mesh, non-woven fabric, fibrous body, foam, porous body, and three-dimensional network structure. Among these, it is particularly preferable to use a sponge. Also, a porous structure made of a sintered polyethylene can be used.

As the sponge, it is preferable to use a polyester-based flexible urethane foam, and it is particularly preferable to use such a urethane foam having a completely open cell structure and reduced pressure loss.
Further, in the present embodiment, the number of cells of the sponge is preferably 5 to 50/25 mm, and more preferably 8 to 40/25 mm, for example. In this embodiment, if the number of cells of the sponge is less than 5/25 mm, the effect of preventing liquid leakage is insufficient, while if it exceeds 50/25 mm, the ink discharge performance is deteriorated.
Moreover, in this embodiment, it is preferable that the thickness of sponge is 3-20 mm, for example, More preferably, it is 5-10 mm.
Note that the number of sponge cells, the thickness of the sponge, and the like may be set to optimum values while being appropriately verified through experiments, depending on the type of ink, viscosity, and the like.

  The impregnation member 606 is preferably arranged in accordance with the space formed between the valve body 605 and the shielding member 607. Specifically, in the present embodiment, as the impregnating member 606, a first sponge 606a and a second sponge 606b are disposed between the stopper 608 and the shielding member 607 inside the recess 605e of the valve body 605. Yes.

  For the shielding member 607, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin, Duracon (polyacetal) (POM), polyvinyl chloride (PVC), polyethylene terephthalate (polyester) (PET), acrylic Etc. can be used. Among them, it is preferable to use polyolefin resins such as polyethylene, low density polyethylene (LDPE), high density polyethylene (HDPE), and polypropylene. Select such a synthetic resin material according to molding or design. Can be used.

  The shielding member 607 is integrally formed with a circular bottom wall 607a, a side wall 607b that rises in a cylindrical shape from the periphery of the bottom wall 607a, and a flange portion 607c that protrudes in a direction of increasing the diameter from the peripheral end of the side wall 607b. It has a cap shape.

  The shielding member 607 is configured to fit the flange portion 607c to the inner peripheral wall 603c on the inner side of the cap body 603 with the inner side of the concave portion 607d formed of the bottom wall 607a and the side wall 607b facing the valve body 605. And fixedly held in the cap body 603.

  At least one or more through holes 609 are formed in the side wall 607b of the shielding member 607. Specifically, in the present embodiment, four through holes 609 arranged at equal intervals are provided around the side wall 607b. The inside and outside of the recess 607d of the shielding member 607 are communicated with each other through the plurality of through holes 609.

  When using the ink supply container 15F with the SS cap 601 having the above-described structure, press the body 602a of the container body 602 with the mouth 602b of the container body 602 facing downward ( Squeeze). At this time, the valve body 605 is elastically deformed by the pressure increase in the container main body 602, and the slit 605a is expanded. As a result, the ink pressurized in the container main body 602 is dispensed from the slit 605 a of the valve body 605.

  On the other hand, by releasing the pressure on the container body 602, the body 602a of the container body 602 is elastically restored to its original shape. At this time, the valve body 605 is elastically deformed by the negative pressure generated in the container body 602, and the slit 605a is expanded. As a result, external air is sucked from the slit 605 a of the valve body 605 and introduced into the container main body 602.

  The ink accommodated in the container main body 602 can be ejected from the slit 605a of the valve body 605 by the squeeze operation as described above. The SS cap 601 does not open the slit 605a unless a certain amount of pressure in the container main body 602 is applied to the valve body 605, so that the ink inside leaks when the mouth portion 602b of the container main body 602 is directed downward. There is nothing.

  By the way, in the SS cap 601, the impregnation member 606 is disposed between the valve body 605 and the shielding member 607 described above. In this case, for example, even when the container main body 602 is repeatedly shaken, the ink outflow pressure (impact) flowing toward the valve body 605 is absorbed by the impregnation member 606, whereby the ink outflow pressure is directly applied to the valve body 605. In addition, since the impregnation member 606 is impregnated with ink, it is possible to reliably prevent the ink from inadvertently ejecting or leaking from the slit 605a of the valve body 605.

  Further, in this SS cap 601, since the shielding member 607 adjusts the flow rate of the ink flowing from the container body 602 side toward the valve body 605 side, the ink is transferred to the valve body 605 when the container body 602 is shaken. The impact to which it goes can be restrict | limited and the inadvertent opening of the valve body 605 by such an impact can be prevented.

  In particular, as in the case of the shielding member 607 described above, with respect to the bottom wall 607a that directly receives the impact of the ink toward the valve body 605, the direction of ink ejection into the recess 607d through the plurality of through holes 609 formed in the side wall 607b. When the ink is introduced from a direction substantially orthogonal to the ink, the impact of the ink toward the valve body 605 when the container body 602 is shaken can be further reduced. As a result, the valve body 605 can be prevented from being inadvertently opened, and the ink can be reliably prevented from inadvertently ejecting or leaking from the slit 605a of the valve body 605.

As described above, in the ink supply container 15F of the present embodiment, even when the container main body 602 is shaken at the time of use, the ink is appropriately discharged from the slit 605a of the valve body 605 without causing liquid leakage. Is possible. In addition, the conventional operation of opening and closing the cap can be omitted, which is very convenient.
Therefore, even when the ink supply container 15F is shaken during use, the ink can be appropriately dispensed without causing liquid leakage, and the operation of opening and closing the cap can be omitted. Therefore, it is possible to further improve the usability of the ink supply container.

  According to the ink replenishing container 15F of the present embodiment, by providing the impregnation member 606, it becomes a resistance when ink is poured out, thereby preventing ink leakage. In addition, after the dispensing, the impregnating member 606 sucks out the remaining ink between the impregnating member 606 and the slit 605a which is the mouth end before the ink drips, thus preventing the ink from dripping (liquid dripping). can do. Accordingly, ink stains around the slit 605a can be suppressed.

Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the scope of the invention.
FIG. 38 is a longitudinal sectional view showing a first modification of the SS cap 601. FIG. 39 is a longitudinal sectional view showing a second modification of the SS cap 601.
Modifications including the first modification and the second modification shown in FIGS. 38 and 39 will be described below.

(1) In the above-described embodiment, the impregnation member 606 is configured to include the first sponge 606a and the second sponge 606b. However, it is not necessarily limited to such a configuration. That is, in order to adjust ink discharge performance (for example, controllability and ease of extrusion), a space formed inside the recess 605e of the valve body 605, and between the stopper 608 and the shielding member 607 is formed. The impregnation member 606 can be disposed in any one of the space and the space formed inside the recess 607d of the shielding member 607.
For example, in the SS cap 601, as in the first modification of the seventh embodiment shown in FIG. 38, the first sponge 606a, the stopper 608, and the shielding member 607 are disposed inside the recess 605e of the valve body 605. In addition, the second sponge 606b and the third sponge 606c may be disposed inside the recess 607d of the shielding member 607. Further, as in the second modification of the seventh embodiment shown in FIG. 39, only the first sponge 606a can be arranged inside the recess 605e of the valve body 605.

  (2) In addition, the number of cells, the thickness, and the like can be varied among the first sponge 606a to the third sponge 606c. In this case, it is preferable to make the number of sponge cells arranged on the valve body 605 side smaller than the number of sponge cells arranged on the container body 602 side, thereby impairing ink discharge performance. Therefore, a sufficient liquid leakage preventing effect can be obtained.

  (3) About the said shielding member 607, in order to adjust the flow volume of the ink which flows toward the valve body 605 side from the container main body 602 side, it can change arbitrarily also about the number of through-holes 609, a magnitude | size, etc. FIG.

  (4) In the SS cap 601, the cap body 603 can be covered with a nozzle cap for discharging ink from the tip of the nozzle instead of the overcap 604 described above.

  (5) A sponge is used as the impregnating member 606 of this embodiment. However, as described above, the impregnating member 606 can be impregnated with ink, and further, when the container body 602 is squeezed, it prevents ink from being discharged from the slit 605a of the valve body 605 and the introduction of outside air. As long as it does not exist, a mesh, a nonwoven fabric, a fibrous body, a foamed body, a porous body, a three-dimensional network structure, or the like may be used in addition to a sponge. Moreover, you may use the porous structure which consists of a sintered compact of polyethylene.

A cover cap 706 is detachably fitted to the shoulder portion 705 on the top of the container main body 702 so as to cover the inner plug 701 from the outside.

  The inner plug 701 has a base 707 and a spout 708. The spout portion 708 can open and close the upper surface of the base portion 707. The base portion 707 and the spout portion 708 are connected by a hinge 711 to form one piece. The hinge 711 is configured by making the resin material thin and giving flexibility.

  In the base 707, an inner cylinder 712 and an outer cylinder 713 are arranged concentrically. The outer cylinder 713 is connected to the inner cylinder 712 by a shoulder 714. When the inner plug 701 is attached to the nozzle portion 703 of the container main body 702 by fitting, the tip 715 of the nozzle portion 703 is inserted between the inner tube 712 and the outer tube 713 until it hits the lower surface of the shoulder 714. And the undercut of the outer cylinder 713 and the undercut of the front-end | tip 715 of the nozzle part 703 are fitted and fixed.

When the pull ring 724 and the cutout portion 723 are removed, the spout 721 is opened. In this state, the spout portion 708 is rotated in the original direction with respect to the hinge 711 to close the base portion 707. As a result, the spout nozzle 726 communicates with the inside of the container main body 702 via the spout 721 so that ink can be poured out.

  Therefore, as shown in FIGS. 48 and 49, when the container main body 702 is grasped by hand and pressed to apply a squeeze operation, the ink 731 of the container main body 702 passes through the fluid passage 718 of the base 707 of the inner plug 701, Pour out from the tip 732 of the spout nozzle 726 of the spout portion 708.

  When the hand squeezing operation is stopped when the predetermined amount of ink 731 is dispensed, the shape and volume of the container body 702 are restored, and the ink 731 in the spout nozzle 726 is sucked back as shown in FIG. Then, the container body 702 returns.

According to the above-described eighth embodiment, the following effects can be achieved.
(1) According to the ink supply container 15G of the present embodiment, in the inner plug 701, the spout nozzle 726 is narrowed to exert a squeeze back effect by squeeze, so that the ink 731 does not remain in the spout nozzle 726. Also, the liquid runs out better. Therefore, the periphery of the spout nozzle 726 is not soiled, the ink 731 does not sag outside the spout nozzle 726, and the amount of spout can be stabilized.

  (2) According to the ink supply container 15G of the present embodiment, in the inner plug 701, the partition plate 720, the score 722, and the pull ring 724 can be provided in the large-diameter fluid passage 718 of the base 707 of the inner plug. It can also have a virgin seal function.

  (3) According to the ink supply container 15G of the present embodiment, since the above-mentioned function is provided, only the number of one-part parts only needs to be increased for the inner plug, so that the productivity of the inner plug is greatly reduced. There is no need to increase the amount of material.

  (4) According to the ink supply container 15G of the present embodiment, even when used for a rigid container that does not exhibit the squeeze-back effect due to squeeze, the spout is narrowed in the inner stopper of the present invention. Becomes better.

  The end opening 817 is smaller in size than the slider 815c, and moves the slider 815c within the range of the protrusion 816 and the end opening 817.

  When the container body 800 is tilted or reversed when ink is dispensed, the slider 815c moves so as to be closest to the opening 815a. On the other hand, when the container main body 800 is returned to the normal posture after the ink is dispensed, the slider 815c moves away from the opening 815a by its own weight or a negative pressure generated by the restoring force of the inner container 802, that is, the end opening. At this time, the residual ink existing on the upper surface of the partition wall 813b is drawn into the storage space of the storage chamber 815 through the opening 815a, thereby preventing dripping.

  A slight gap may be formed between the slider 815c and the peripheral wall forming the storage chamber main body 815b, but the gap setting is set so that residual ink does not pass through the gap in consideration of the surface tension of the ink. Thus, the residual ink is reliably stored in the storage space, and the ink (residual ink) that has been in contact with the outside air is prevented from entering the container main body 800 through the storage chamber main body 815b.

  The slider 815c can be made of a synthetic resin or a metal, and particularly when a metal is used, the slider 815c can be smoothly moved by its own weight and further enhance the suck back effect. Can do. When the slider 815c is made of a metal member, the surface of the slider 815c covered with a resin may be used, so that the ink quality is stably maintained.

  In this example, the slider 815c is shown as a spherical body. However, the shape of the slider 815c can be changed as long as it can be smoothly moved in the storage chamber body 815b, and is not limited to the illustrated one. The slider 815c is designed so that ink and / or air does not substantially flow into the inner container 802 over the slider 815c.

  Reference numeral 818 denotes an outside air introduction hole provided at at least one (preferably two) step portion of the top wall 803b of the base 803 and connecting the inside and outside of the base 803. Reference numeral 819 denotes a lateral opening provided in the mouth and neck portion 801a of the outer container 801 and connected to the inner container 802. Reference numeral 820 denotes a through passage provided in the cylindrical body 813c of the inner plug 813. Reference numeral 821 denotes a longitudinal groove provided on the outer wall of the mouth-and-neck portion 801a of the outer container 801.

  When outside air enters the base 803 through the outside air introduction hole 818, the outside air is introduced between the inner container 802 and the outer container 801 through the through passage 820, the longitudinal groove 821, and the opening 819.

  Reference numeral 822 denotes an outside air introduction valve integrally connected in a cantilevered state to the outer wall of the cylindrical body 814a constituting the valve body 814. The outside air introduction valve 822 has a disc-shaped elastic tongue whose free end is detachably abutted against a valve seat 803e provided on the lower surface of the top wall 803b of the base 803 and holds the outside air introduction hole 818 in a closed state. It is composed of pieces.

  The outside air introduction valve 822 is opened when the outer container 801 is restored to the initial shape by removing the force (squeezing force) applied to the body portion of the outer container 801, and the inner container 802 and the outer container 801 are opened. The outer container 801 quickly returns to its initial shape by introducing outside air between the two and the container, and when the inner container 802 is crushed by a squeeze operation, the outer container 801 is kept closed and filled into the inner container 802. Make sure the ink is discharged.

  The outside air introduction valve 822 and the valve body 814 can be integrally connected to each other via the cylinder body 814a, thereby reducing the number of parts. However, the outside air introduction valve 822 and the cylinder body 814a can be reduced. May be constituted by another member, and this point is not limited.

  In the ink supply container 15H, which is a squeeze container having the above-described configuration, in order to pour out the ink filled in the inner container 802, the container body 800 is tilted and held in an inverted posture so that the body portion of the outer container 801 is Squeeze. As a result, the volume of the inner container 802 is reduced (reduced), and the ink filled therein is discharged from the opening of the dispensing cylinder 803c through the mouth neck portion 802a and the through-hole 813a of the inner plug 813. At this time, the slider 815c is located at a position close to the opening 815a (a portion where the protrusion 816 is provided).

  When the squeeze operation is stopped, the through-hole 813a is immediately closed by the valve body 814, and the elastic tongue of the outside air introduction valve 822 is separated from the valve seat portion 803e formed on the top wall 803b to introduce outside air. The hole 818 is opened, whereby the outer container 801 quickly returns to the initial shape (the shape before being crushed) by the introduction of the outside air between the outer container 801 and the inner container 802.

  When the container body 800 is returned to the normal posture (standing posture) in accordance with the stop of the squeeze operation, the ink remaining in the space from the dispensing cylinder 803c to the valve body 814 is directed toward the end opening 817 by the slider 815c. During the movement, it is drawn into the storage space of the storage chamber 815 by the suck back accompanying the movement of the slider 815c.

  The amount of ink drawn is determined by the amount of movement of the slider 815c and the volume of the storage space, and this point is appropriately set.

  In FIGS. 56 and 57, the outer container 801 is formed of an outer layer body, the inner container 802 is formed of an inner layer body, and the inner layer body (inner container) 802 becomes an outer layer as the amount of ink discharged increases. An ink supply container 15H as a delamination-type squeeze container that is peeled off from the body (outer container) 801 and reduced in volume is shown as an example. However, the present invention can also be applied to a double container in which an inner container 802 filled with ink is assembled inside the outer container 801, or a single-layer container having no inner container, and is limited to the illustrated one. It will never be done.

  In the above embodiment, the case where the storage chamber 815 in which the storage space is formed by the bottomless cylindrical peripheral wall provided with the terminal opening 817 is applied to the lower portion of the storage chamber main body 815b is shown. It is also possible to use one having In this case, at least one conductive groove extending from the opening 815a toward the bottom is provided on the inner surface of the peripheral wall of the storage chamber main body 815b, and the residual ink is poured into the bottom through the conductive groove, thereby smoothly moving the slider 815c. Movement is possible.

  The cap used for the ink replenishing container 15H of this embodiment is such that the ink flows down from the outer peripheral wall of the dispensing cylinder 803c along the top wall 803b of the base 803 due to liquid dripping, and the ink is engaged with the lid 804 and the base 803. Even if it adheres to and is dried and solidified, the notch portion 811 makes it easy to release the engagement of the inner annular body 804b with the annular linkage portion 810, so that a large force is applied when the lid body 804 is opened. There is no need for smooth opening.

  In addition, the dripping ink is stored in the pool groove 812, and the amount of ink attached to the engaging portion can be reduced.

  According to the ink supply container 15H of the present embodiment, when the ink adheres to the engaging portion between the lid 804 and the base 803 due to dripping and dries and solidifies due to the cap, the slip in the engaging portion becomes worse. Even if it exists, the cover body 804 can be opened smoothly.

  Further, according to the ink supply container 15H of the present embodiment, an ink supply container having a high sealing property that can prevent the intrusion of moisture into the lid 804 by the cap can be provided.

  The ink supply container 15H of the present embodiment can perform the ink dispensing in a plurality of parts.

  The ink supply container 15H according to the present embodiment is provided with a notch 811 in the inner annular body 804b corresponding to the portion where the ink tends to accumulate in the cap. The notch portion 811 facilitates the release of the inner annular body 804b from the annular linkage portion 810, so that it is not necessary to apply a large force when the lid body 804 is opened, and a smooth opening is possible.

A threaded portion is formed on the outer peripheral surface of the mouth portion of the container body, and the cap is formed with a threaded portion that is screwed with the threaded portion. Solidification due to residual ink can be prevented by cutting out a part of the screw portion.
Further, in the case of an ink supply container provided with a seal member or the like on the top surface of the mouth of the container body, solidification of residual ink can be prevented by cutting out a part of the top surface portion.

[Eleventh embodiment]
Hereinafter, the ink supply container 15J of the present embodiment will be described with reference to the drawings.

FIG. 63 is a cross-sectional view showing the cap 110 of the ink supply container 15J according to the eleventh embodiment.
The ink supply container 15J of the present embodiment is generally configured to include a container body 190 filled with ink and an ink dispensing cap 110. The ink ejection cap 110 includes a cap body 120 attached to the opening 191 of the container body 190 and a cover cap 140 connected to the cap body 120 through a hinge 130 so as to be opened and closed.

  The cap 110 can be manufactured by a known manufacturing method such as injection molding or compression molding using a normal plastic material such as polypropylene. Generally, the cap body 120, the hinge 130, and the cover cap 140 are integrally formed.

  The ink supply container 15J using the dispensing cap 110 of the present embodiment is not particularly limited as the container body 190, but in the case of ink having a high viscosity, a soft plastic container having squeeze properties is preferably used. The ink supply container 15J is provided in a state where the cap 110 is attached to a container body 190 that is filled with ink and then sealed by sealing the opening 191 with an aluminum foil film.

  When using the ink supply container 15J, the user once removes the cap 110 from the container main body 190, peels off the aluminum foil film from the opening 191 of the container main body 190, opens the cap 110, and uses the cap 110 again.

  The cap main body 120 includes a top plate 150 that seals the opening 191 of the container main body 190, and an outer cylindrical portion 160 that hangs down from the outer peripheral edge of the top plate 150 and engages with the outer peripheral edge of the opening 191 of the container main body 190. And a pouring tube 170 projecting on the top plate 150 and communicating with the inside of the container.

  The extraction cylinder 170 is provided so as to be offset in the direction opposite to the connection side of the hinge 130. In this embodiment, the center line of the extraction cylinder 170 is eccentric from the center line of the cap body 120. Thereby, it is possible to reduce the inclination of the container when pouring out highly viscous ink, to obtain an effect such that the pouring cylinder 170 is easily hidden without being hidden by the cover cap 140, and the top plate 150 is not easily soiled with ink.

  Further, in the present embodiment, an inner screw 161 is provided on the inner wall of the outer cylindrical portion 160 and is screwed into the container main body 190 until the lower surface of the top plate 150 contacts the opening 191 top surface of the container main body 190.

  The communication hole connecting the tip spout 171 and the container-side opening 172 provided in the dispensing tube 170 has a straight part 173 having a substantially constant inner diameter and a container-side end of the straight part 173 from the container-side end toward the container-side opening 172. The diameter-enlarged portion 174 is gradually expanded. The edges of the spout 171 and the container side opening 172 can be appropriately chamfered or rounded.

  As described above, when the user finishes dispensing the ink, the squeeze of the container is stopped and the posture is restored. At this time, the ink in the vicinity of the spout 171 or in the spout cylinder 170 communication hole is collected into the container main body 190 by its own weight and suck back, but tends to remain when the viscosity of the ink is high. For this reason, the ink may spill out from the spout 171 and the surroundings may be soiled, or the ink may be fixed in the communication hole to deteriorate the dischargeability.

  In the present embodiment, the dispensing cylinder 170 is configured as described above, and by specifying the inner diameter of the straight portion 173, the ink dispensing property is excellent, and the liquid draining property and the liquid returning property after dispensing are completed. An excellent cap 110 can be obtained.

  In the inner diameter D of the straight portion 173, the smaller the inner diameter D is, the higher the liquid return effect by suckback is. However, when the diameter is smaller than a specific range, the pouring property is deteriorated and the liquid remaining in the vicinity of the spout 171 is likely to occur. Further, the larger the inner diameter D of the straight portion 173, the higher the liquid return effect due to its own weight. However, if the straight portion 173 is larger than a specific range, the suck back is less likely to occur and the liquid tends to remain on the peripheral wall in the communication hole. The inner diameter D of the straight portion 173 may be set to a specific range as appropriate in accordance with the viscosity of the ink to be filled.

Moreover, the liquid return effect by own weight can be enlarged by making it into the enlarged diameter part 174 which diameter-expands from the container side termination | terminus of the straight part 173 to the container side opening part 172 gradually.
The opening diameter of the container-side opening 172 is preferably increased in a range where the container-side opening 172 does not reach the contact position with the top surface of the opening 191 of the container main body 190. There will be a gap between the lower surface of the container and the top surface of the opening 191 of the container body 190, which may result in incomplete sealing of the container. The taper angle θ1 of the enlarged diameter portion 174 shown in FIG. 63 may be set as appropriate in consideration of the relationship between the viscosity of the ink, the height of the dispensing cylinder 170, the eccentric amount d, and the like.

  It is important for the straight portion 173 to have a predetermined length in order to obtain a stable pouring property and to enhance the liquid return effect by suck back. The length L from the spout 171 to the boundary of the enlarged diameter portion 174 is preferably set in a ratio with the communication hole length h while balancing the stable pouring property and the liquid return effect by suck back.

  The dispensing cylinder 170 of the present embodiment is basically cylindrically symmetric and the height of the back is not different from the conventional one, so that the manufacturing cost of the molding die is not increased.

  The cover cap 140 of the present embodiment includes a canopy portion 141 that covers the entire top plate 150 of the cap body 120 and a sealing portion that fits and seals the spout 171 at the tip of the spout tube 170 when the cover cap 140 is closed. 142 and an engaging portion 143 that engages with the cap main body 120 to lock the cover cap 140. On the opposite side of the position where the hinge 130 on the outer peripheral edge of the canopy 141 is connected, a finger hook 144 protrudes in a hook shape.

  Corresponding to the engaging portion 143 of the cover cap 140, a rising portion 180 is provided on the outer peripheral edge of the top plate 150 of the cap body 120, and the engaging portion 143 of the cover cap 140 is engaged with the outer peripheral side of the rising portion 180. A mating engaging portion 181 is provided. Further, the outer cylinder portion 160 of the cap body 120 is provided with a stepped portion 162 that is slightly thinned at a corresponding position in order to improve the operability of the finger hook 144.

  Conventionally, this kind of hinge cap has a bumpy protrusion with a large diameter in the middle of the seal part, and this part fits into the dispensing cylinder to lock the cover cap. There were many hinge caps for. In the case of such a configuration, for example, if ink remains in the dispensing cylinder, it may stick to the periphery of the locking portion, thereby hindering the opening / closing operation of the cover cap.

  In the present invention, the engagement portion 143 is provided separately from the seal portion 142, and the seal portion 142 is formed in a cylindrical shape so as to be in sliding contact with the straight portion 173 in the extraction tube 170 to seal the spout 171. Yes. With this configuration, even if ink remains in the dispensing cylinder 170, the seal portion 142 is not fixed, and the cover cap 140 can be opened and closed smoothly all the time.

In addition, the inner wall of the rising portion 180 is an inclined surface 182 that rises smoothly at an angle θ2 from the plane formed by the top plate 150, so that even if ink spills and adheres to the top plate 150, it is easy. Can be wiped off. Note that the angle θ2 may be set as appropriate.
In the present embodiment, the rising portion 180 is provided on the entire circumference, but it may be provided only at a position corresponding to the engaging portion 143 of the cover cap 140.

  The ink supply container 15J of this embodiment is particularly effective for ink having a relatively high density, but can also be effective for ink having a normal density.

The configuration and operation of the ink supply container have been described above, but the usage described below is also possible.
The ink supply container 15 of the first embodiment, the ink supply container D of the fifth embodiment, and the ink supply container 15F of the seventh embodiment to the ink supply container 15J of the eleventh embodiment described above are ink from the ink supply container. Used to supply ink to the tank 9. However, the present invention is not limited to this, and when ink is supplied to another ink supply container instead of the ink tank 9, the same method as that of the present embodiment is used using each of the ink supply containers described above. It is possible to achieve the same effect. As a result, for example, when the supply to the ink tank is switched to a new ink supply container, and the ink tank cannot be supplied to the ink tank with the previous ink supply container, the ink is transferred from the previous ink supply container to the new ink supply container. By replenishing the ink, it becomes possible to use the ink in the previous ink supply container without wasting it.

  In the ink supply container 15J of the eleventh embodiment from the ink supply container 15 of the first embodiment described above, each ink supply container is filled with ink. However, the present invention is not limited to this, and a cleaning agent may be filled instead of the ink.
