Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a packaging container (storage container) suitable for packaging inkjet cartridges, which are contents (items to be packaged) that are undesirable for impact due to vibrations, drops, etc. .

[Background technology]

Conventionally, as a method to protect contents that are easily damaged in packaging, packaging materials with shock-absorbing properties such as paper, cardboard, foam sheets, resin molded products such as styrofoam and polyurethane have been used.

[Problem that the invention is trying to solve]

When packaging using cardboard boxes, the cardboard itself does not necessarily have sufficient local strength, and when force is applied to a localized area, it is easy to dent or damage that area, which often extends to the contents. .

In particular, it is good if the contents match the size of the cardboard, but if the contents have unevenness or the size does not match the cardboard, local forces may be applied to the packaging due to impact from drops or vibrations. Doing so will not only damage the packaging, but also easily cause deformation and damage to the contents.

Similarly to cardboard boxes, when packing in boxes made of paper, resin, wood, etc., if the contents do not match the shape of the storage area, the contents may dance around inside the box while the package is being transported. The impact may cause some damage to the contents.

Additionally, cardboard boxes and paper are relatively expensive.

On the other hand, a method of packaging the contents by wrapping them around the contents using foam sheets such as Etherhome (product name) or sheets with air bubbles known under the product name of Airbag as impact cushioning material is called protection of the contents. It is possible to obtain some satisfactory results. However, wrapping and fixing these sheets around the contents, packaging them with exterior materials such as boxes and packages, and packaging operations are complicated. Furthermore, packaging costs are high, and the wrapping of these sheets increases the volume, requiring larger outer packaging materials and requiring more space during transportation and storage. have.

Moreover, even when these sheets are used, their protective function is not necessarily satisfactory when the contents have complex irregularities.

Another method of protecting the contents when packaging contents that are easily damaged is to use a foamed resin molded product with a shock-absorbing effect as a shock-absorbing material in the packaging.

Typical foamed resins include urethane foam and styrene foam, but styrene foam is often used due to its cost.

Styrofoam can be easily molded to match the shape of the contents, and has good shock-absorbing properties, so
By using a case and a protective member made of styrofoam molded products, the contents within the package can be easily protected and fixed in position.

However, in order to obtain sufficient shock-absorbing properties in a foamed polystyrene molded product, the wall thickness must be increased, which increases the volume of the packaged product and requires a larger space for transportation and storage.

For example, the volume of a case made of polystyrene foam molded product or a package using a protective member for shock absorption and position fixation of contents is usually 2 to 2 times the volume of a package using only a cardboard box.
Reaching 3 times.

Such a significant increase in occupied space has placed a heavy burden on warehouse space and logistics costs.

Note that the strength of the Styrofoam molded product itself is not very high, and it is easily torn due to local impact, so it is common to insert a sleeve-shaped cardboard sheet over the Styrofoam case or cover it with cardboard. target,
Packaging costs are also high.

In addition, like a blister bag, a vacuum-formed container body made of vinyl chloride, a layer of vinyl chloride is provided at the adhesive part of the container body, and a thick paper is bonded to the container body as a bottom plate. There is a combination of packaging materials.

This packaging material has both the function of an individual packaging box and the function of protecting the contents. However, they are not necessarily sufficient in terms of their ability to protect the contents, and are generally used for items that have high strength and are difficult to break or deform, or items that will cause little damage even if broken.

As described above, it is currently difficult to find a packaging material that satisfies the requirements in terms of protection of contents, space occupied by the packaged items, cost of packaging, etc.

Furthermore, if it is important to protect the contents as well as maintain the humidity environment, more advanced and complicated packaging techniques are required, and such packaging techniques result in higher packaging costs. This is normal.

For example, the contents are placed in a bag made of a thin aluminum film to prevent moisture, the bag is sealed, and the bag is further packaged using the method described above.
Alternatively, there is a method of storing the inkjet recording head in a strong case made of an aluminum plate together with various shock absorbing materials.

However, in either method, the cost of the members necessary for packaging is high, and the protective function is not necessarily sufficient in many cases. Moreover, it has the disadvantage that its airtightness is likely to be impaired if it collides with other articles or is dropped during transportation. Furthermore, in the case of aluminum boxes, there are many cases where they become deformed.

The present invention solves the above-mentioned problems with conventional packaging materials, satisfies the requirements for protection of the contents, the space occupied by the packaged items, the cost of packaging, etc., and is capable of maintaining the humidity environment of the contents. The purpose of the present invention is to provide a cartridge storage container (packing container).

[Means to solve the problem]

An inkjet cartridge storage container of the present invention capable of solving the above-mentioned problems includes a plate-like member and a container body that forms a storage space for the inkjet cartridge by being joined to the plate-like member, The container body has a wall portion that is maintained in a non-contact state with the inkjet cartridge, and a recess that protrudes from the wall portion into the storage space and contacts and supports the inkjet cartridge, It is characterized in that a cover member is provided on the discharge port surface to cover the discharge port.

Further, the storage container for an inkjet cartridge of the present invention includes a plate-shaped member and a container body that is joined to the plate-shaped member to form a storage space for the inkjet cartridge, and the container body is configured to accommodate the inkjet cartridge. and a recess that protrudes from the wall into the storage space and contacts and supports the inkjet cartridge, and the plate-like member has a multilayer structure. , characterized in that it has a moisture-proof layer as the outermost layer when viewed from the storage space.

(The following is a blank space) [Example] Figures 2 to 6 show preferred inkjet units IJU, inkjet heads IJH, ink tanks IT, inkjet cartridges IJC, and inkjet recording apparatus main bodies IJRA to which the present invention is implemented or applied.
, carriage HC and their relationships. The configuration of each part will be explained below using these drawings.

As can be seen from the perspective view in Fig. 3, the inkjet cartridge IJC in this example has a large ink storage ratio, and the tip of the inkjet unit IJU protrudes slightly from the front surface of the ink tank IT. It has a shape. This inkjet cartridge IJC is fixedly supported by a positioning means and electrical contacts (described later) of a carriage HC (FIG. 5) placed on the inkjet recording apparatus main body IJRA, and is detachable from the carriage HC. It is a disposable type. The configurations shown in FIGS. 2 to 6 of this example are those to which a number of novel techniques developed at the stage of the establishment of the present invention are applied, so while briefly explaining these configurations,
I will explain the whole thing.

(i) Inkjet unit IJU configuration description The inkjet unit IJU is a bubble jet type unit tearer that performs recording using an electrothermal converter that generates thermal energy to cause film boiling in ink in response to an electrical signal. Ru.

In FIG. 2, reference numeral 100 is composed of electrothermal converters (discharge heaters) arranged in a plurality of rows on a Si substrate, and electrical wiring such as Aβ for supplying electric power to the converters, which are formed by film-forming technology. It's a heater board.

200 is a wiring board for the heater board 100;
Wiring corresponding to the wiring of the heater board 100 (for example, connected by wire bonding) and a pad 201 located at the end of this wiring and receiving electrical signals from the main device.
It has

1300 is a grooved top plate provided with partition walls for dividing a plurality of ink channels and a common liquid chamber for storing ink to supply ink to each ink channel, and is supplied from an ink tank IT. An ink receiving port 1500 that receives ink and introduces it into the above-mentioned common liquid chamber, and an orifice plate 400 having a plurality of ejection ports corresponding to each ink flow path are integrally molded. Polysulfone is preferred as the material for molding, but other resin materials for molding may also be used.

Reference numeral 300 denotes a support made of metal, for example, which supports the back surface of the wiring board 200 on a flat surface, and serves as a bottom plate of an inkjet unit. Reference numeral 500 denotes a pressing spring, which is M-shaped and presses the common liquid chamber with light pressure at the center of the M-shape, and concentrates linear pressure on a part of the liquid path at the front part 501, preferably in the area near the discharge port. Press.

The foot of the spring that presses the heater board 100 and the top plate 1300 passes through the hole 3121 of the support body 300 and engages with the back side of the support body 300, thereby engaging the two in a state where they are sandwiched between them. The heater board 100 and the top plate 1300 are crimped and fixed by the concentrated biasing force of the spring 500 and its front sagging portion 501. The support body 300 also has positioning holes 312, 1900, and 2000 that engage with the two positioning protrusions 1012 and the positioning and heat-sealing holding protrusions 1800 and 1801 of the ink-kunk IT.
It has protrusions 2500 and 2600 on the back side for positioning the device body IJRA with respect to the carriage HC. In addition, the support 300 also has a hole 320 that allows an ink supply pipe 2200 (described later) to pass therethrough, which allows ink to be supplied from an ink tank. The wiring board 200 is attached to the support body 300 by adhering it with an adhesive or the like.

Note that the recesses 2400 and 2400 of the support body 300 are provided near the positioning protrusions 2500 and 2600, respectively, so that the assembled inkjet cartridge IJ
C (Fig. 3), the three sides around it are parallel grooves 300.
At the extension point of the head tip area formed by a plurality of .
0,. It is located so that it will not reach 2600. This parallel groove 3000 is formed. As can be seen in FIG. 5, the lid member 800 forms the outer wall of the inkjet cartridge IJC, and together with the ink tank forms a space in which the inkjet unit IJU is accommodated. Further, the ink supply member 600 in which the parallel groove 3001 is formed connects the ink conduit 1 600 that is continuous to the ink supply pipe 2200 described above to the supply pipe 22.
The 00 side is formed as a fixed cantilever beam, and a sealing bottle 602 is inserted to ensure capillary action between the fixed side of the ink conduit and the ink supply tube 2200. Note that 601 is a packing that seals the connection between the ink tank IT and the supply pipe 2200, and 700 is a filter provided at the tank side end of the supply pipe.

Since this ink supply member 600 is molded, it is not only inexpensive and has high positional accuracy and eliminates deterioration in manufacturing precision, but also has a cantilevered conduit 1600, so that it can be used in mass production as described above for the conduit 1600. The state of pressure contact with the ink socket 1 500 can be stabilized. In this example, a more complete communication state can be reliably obtained by simply pouring the sealing adhesive from the ink supply member side under this pressure-contact state. Note that the ink supply member 600 is fixed to the support body 300 through holes 1901.
The backside bottle of the ink supply member 600 with respect to 1902 (
This can be easily accomplished by projecting a hole (not shown) through the holes 1901 and 1902 of the support 300 and heat-sealing the protruding portion to the back side of the support 300. Note that this slightly protruding area of the heat-sealed back surface is the ink tank IT.
Since the unit IJU is housed in a recess (not shown) in the side wall surface of the mounting surface of the inkjet unit IJU, the positioning surface of the unit IJU can be accurately obtained.

(ii) Ink tank IT configuration description The ink tank is assembled by inserting the cartridge main body iooo, the ink absorber 900, and the ink absorber 900 from the side opposite to the unit IJU mounting surface of the cartridge main body iooo. and a lid member 1100 for sealing.

Reference numeral 900 denotes an absorber for impregnating ink, and is disposed within the cartridge body 1000.

1200 is a unit I consisting of each of the above parts 100 to 600.
It is a supply port for supplying ink to the JU, and also impregnates the absorber 900 with ink by injecting ink from the supply port 1 200 in a process before placing the unit in the portion 1010 of the cartridge body 1000. It is also an injection port for doing this.

In this example, the parts that can supply ink are the atmospheric transport port and this supply port, but the ribs 2300 in the main body 1000 and the lid member 1100 are used to ensure good ink supply from the ink absorber. The air presence area in the tank formed by the ribs 2500 and 2400 is connected to the air vent 14.
Since the ink is formed continuously from the 01 side and extends over the farthest corner area from the ink supply port 1200, a relatively good and uniform ink supply to the absorber can be achieved from the supply port 1 200 side. It is important that this is done.

This method is extremely effective in practice. This rib 1000
is on the rear surface of the ink tank main body 1000,
It has four ribs parallel to the direction of carriage movement to prevent the absorbent body from coming into close contact with the rear surface. Also, partial rib 2
400 and 2500 are similarly provided on the inner surface of the lid member 1100 on corresponding extensions to the rib 1000, but unlike the rib 1000, they are in a divided state and the space where air is present is separated from the former. It is increasing. still,
The partial ribs 2500 and 2400 are distributed over half or less of the total area of the lid member 1000. These ribs made it possible to more stably guide the ink in the region of the corner of the ink absorber farthest from the tank supply port 1200 to the supply port 1200 side reliably by capillary force. 1
Reference numeral 401 denotes an atmosphere communication port provided in the lid member to communicate the inside of the cartridge with the atmosphere. 1400 is atmospheric communication port 1
This is a liquid-repellent material placed inside the air vent 401, thereby preventing ink from leaking from the air vent 1400.

The ink storage space of the ink tank IT mentioned above has a rectangular shape, and the long sides are on the sides, so the arrangement of the ribs described above is particularly effective. In the case of a case or a cube, cover member 1
By providing ribs throughout the ink absorber 900, the ink supply from the ink absorber 900 can be stabilized. A rectangular parallelepiped shape is suitable for storing as much ink as possible within a limited space, but in order to use the stored ink for recording without wasting it, as mentioned above, it is necessary to It is important to provide ribs that can perform the above-mentioned action on two adjacent surface areas. Furthermore, the inner surface ribs of the ink tank IT in this embodiment are arranged in a substantially uniform distribution in the thickness direction of the rectangular parallelepiped-shaped ink absorber. This configuration is important because it can equalize the atmospheric pressure distribution and almost eliminate the remaining amount of ink with respect to the ink consumption of the entire absorber. Furthermore, to explain the technical idea behind the arrangement of the ribs in detail, the ink supply port 1 of the ink tank is located on the quadrangular top surface of the rectangular parallelepiped. When an arc is drawn with the long side as the radius centered on the projected position of 2 0 0, for the absorber located outside of the arc,
It is important to arrange the ribs on the outer surface of the arc so that atmospheric pressure can be applied quickly. In this case, the atmosphere inlet of the tank is not limited to this example, as long as it is at a position where the atmosphere can be introduced into the region where the ribs are provided.

In addition, in this embodiment, the inkjet cartridge I
The rear surface of the JC head is flattened to minimize the space required when incorporated into the device, and the structure maximizes the ink storage capacity, allowing the device to be made more compact. It has an excellent structure that not only allows the cartridge to be removed, but also reduces the frequency of cartridge replacement. Then, by utilizing the rear part of the space for integrating the inkjet unit IJU, a protruding part for the air transport port 140L is formed therein, and the interior of this protruding part is hollowed out to form the above-mentioned structure. An atmospheric pressure supply space 1402 is formed for the entire thickness of the absorber 900. With this configuration, we were able to provide an excellent cartridge that has never been seen before. Note that this atmospheric pressure supply space 1402 is a much larger space than the conventional one, and the above-mentioned atmospheric air passage port 1401 is located above, so even if the ink leaves the absorber due to some abnormality, this large space will not be affected. The air pressure supply space 1402 can temporarily hold the ink and ensure that the ink is collected by the absorber, so that an excellent cartridge with no waste can be provided.

Further, the structure of the mounting surface of the unit IJU of the ink tank IT is shown in FIG. Let L be a straight line that passes approximately through the center of the protruding opening of the orifice plate 400 and is parallel to the mounting reference plane of the bottom surface of the tank IT or the surface of the carriage.
The two positioning protrusions 1012 are on this straight line L. The height of this protrusion 1012 is slightly lower than the thickness of the support 300, and positions the support 300. In this drawing, the carriage positioning hook 4 is located on the extension of the straight line L1.
Claw 21 that engages with 90” square engagement surface 4002 of 001
00 is located, and the positioning force for the carriage is designed so that it acts in a plane area parallel to the reference plane that includes this straight line L1. As will be described later in Figure 5,
These relationships are effective because the positioning accuracy of only the ink tank is equivalent to the positioning accuracy of the ejection ports of the head.

Further, a hole 19 for fixing the support body 300 to the side surface of the ink tank is provided.
Ink tank protrusions 18 corresponding to 00.2000 respectively
00.1801 is longer than the above-mentioned protrusion 1012, and the part that protrudes through the support 300 is thermally fused to form the support 3.
This is for fixing 00 to its side. Let I,3 be a straight line that is perpendicular to the above-mentioned line L1 and pass through this protrusion 1800, and let L2 be a straight line that passes through the protrusion 180l.Since the approximate center of the supply port 1200 is located on the straight line L3, This is a preferable configuration because it acts to stabilize the connection between the port 1200 and the supply pipe 2200, and reduces the load on the connection due to drops or impacts. or,
The straight lines Lx and L- do not match, and the head I. There are protrusions 1800 and 1801 around the protrusion 1012 on the discharge port side of JH.
The presence of the head IJH further strengthens the positioning of the head IJH with respect to the tank. Note that the curved line indicated by L4 is the position of the outer wall when the ink supply member 600 is attached. Since the protrusions 1800 and 1801 are along the curve L4, they provide sufficient strength and positional accuracy for the weight of the distal end side configuration of the head IJH. 2700 is the tip of the ink tank IT, which is attached to the front plate 40 of the carriage.
This is provided in case of an abnormal situation where the ink tank is inserted into the 00 hole and the displacement of the ink tank becomes extremely poor.

210l is a retainer for the carriage, which is provided to a bar (not shown) of the carriage HC, and is attached to a bar (not shown) of the cartridge I.
This is a protective member for maintaining the mounted state even if a force is applied in the upward direction that causes the JC to enter the lower part of the bar at the pivoted mounted position and unnecessarily disengage from the positioned position as will be described later.

The ink tank IT has a shape that surrounds the unit IJU except for the lower opening by covering it with the lid 800 after the unit IJU is installed. Since the opening is close to the carriage HC, a substantial four-sided surrounding space is formed. Therefore, although the heat generated from the head IJH in this enclosed space is effective as a heat-retaining space, the temperature rises only slightly during long-term continuous use. For this reason, in this example, a slit 1700 with a width smaller than this space is provided on the upper surface of the cartridge IJC in order to assist the natural heat dissipation of the support, thereby preventing temperature rise and controlling the temperature distribution of the entire unit IJU. We were able to make uniformity independent of the environment.

When assembled as an inkjet cartridge IJC, ink is supplied from inside the cartridge into the supply tank 600 through the supply port 1200, the hole 320 provided in the support 300, and the introduction port provided on the inner back side of the supply tank 600. After passing through the interior, the ink flows into the common liquid chamber from the outlet through an appropriate supply pipe and the ink inlet 1500 of the top plate 400. A packing made of, for example, silicone rubber or butyl rubber is disposed at the above-mentioned connection portion for ink communication, and this seals the ink supply path to ensure an ink supply path.

In this embodiment, the top plate 1300 is made of a resin such as polysulfon, polyethersulfon, polyphenylene oxide, or polypropylene, which has excellent ink resistance, and the orifice plate 400 and other resins are simultaneously molded together in the mold. It's molded.

As mentioned above, the integrally molded parts include the ink supply member 600,
Top plate and orifice plate integrated, ink tank body 1
000, which not only achieves a high level of assembly accuracy but also is extremely effective in improving quality in mass production. Furthermore, since the number of parts can be reduced compared to the prior art, excellent desired characteristics can be reliably exhibited.

In addition, in the embodiment of the present invention, in the above-mentioned shape after assembly,
As shown in FIGS. 2 to 4, the ink supply member 6
00, the upper surface part 603 is the third one between the end part 4008 of the roof part provided with the slit 1700 of the ink tank IT.
As shown in the figure, a slit S is formed between the lower surface portion 604 and the head side end portion 4011 of the thin plate member to which the lower part 1800 of the ink tank IT is bonded, and a slit similar to the above slit S (not shown). is formed. These slits between the ink tank IT and the ink supply member 600 substantially act to further promote heat dissipation through the slit 1700, and even if there is unnecessary pressure applied to the tank IT, it is directly removed from the supply member. In particular, this prevents the inkjet unit ■JT from being affected.

In any case, the above-mentioned configuration of this embodiment is a configuration that has not been seen in the past, and each of them individually provides an effective effect, and in combination, each component provides an organic configuration. ing.

(iii) Description of attaching the inkjet cartridge IJC to the carriage HC In FIG. 5, 5000 is a platen roller that guides the recording medium P from the bottom to the top of the page.

The carriage HC moves along the platen roller 3000, and has a front plate 40 located on the front side of the inkjet cartridge IJC on the front platen side of the carriage.
00 (thickness: 2 mm) and a flexible sheet 4005 equipped with pads 2011 corresponding to the pads 201 of the wiring board 200 of the cartridge IJC, and for generating elastic force to press this against each pad 2011 from the back side. An electrical connection support plate 4003 that holds a rubber pad sheet 4007, and an inkjet cartridge IJ.
Positioning hook 400 for fixing C to the recording position
1 is provided. The front plate 4000 has two positioning projecting surfaces 4010 corresponding to the aforementioned positioning projections 2500 and 2600 of the cartridge support 300, respectively, and receives a vertical force toward these projecting surfaces 4010 after the cartridge is mounted. For this reason, the front plate has a plurality of reinforcing ribs (not shown) on the platen roller side facing in the direction of the perpendicular force.

This rib is located at the front position L when the cartridge IJC is installed.
A head protection protrusion that protrudes slightly (approximately 0.1 mm) toward the platen roller is also formed.

The electrical connection support plate 4003 has a plurality of reinforcing ribs 4004 not in the direction of the ribs but in the vertical direction, and the proportion of lateral protrusion decreases from the platen side toward the hook 4001 side. This also serves the function of tilting the position when the cartridge is installed as shown in the figure.

In addition, in order to stabilize the electrical contact state, the support plate 4003 is used to position the hook side to apply force to the cartridge in the opposite direction to the direction in which the two positioning protruding surfaces 4010 act on the cartridge. It has two surfaces 4006 corresponding to the protruding surfaces 4010, forming a pad contact area between them and uniquely defining the deformation amount of the notch of the rubber seat 4007 with a notch corresponding to the butt 2011. These positioning surfaces come into contact with the surface of the wiring board 300 when the cartridge IJC is fixed at a recordable position. In this example, the wiring board 300
Since the pads 201 are distributed symmetrically with respect to the line LI, the amount of deformation of each notch of the rubber sheet 4007 is made uniform, thereby making the contact pressure of the pads 2011 and 201 more stable. The distribution of pads 201 in this example is two rows above, two rows below, and two columns vertically.

The hook 400l has an elongated hole that engages with the fixed shaft 4009, and uses this elongated movement space to rotate counterclockwise from the position shown in the figure, and then moves to the left along the platen roller 5000. By doing so, the inkjet cartridge IJC is positioned with respect to the carriage HC. The hook 4001 may be moved in any way, but a configuration in which it can be moved using a lever or the like is preferable. In any case, when the hook 4001 is rotated, the cartridge IJC moves toward the platen roller and the positioning protrusion 2500.2600
moves to a position where it can come into contact with the positioning surface 4010 of the front plate, and as the hook 400l moves to the left, the hook surface 4002 at 90' comes into contact with the claw 2100 at 90' of the cartridge IJC.
Position the cartridge IJC while keeping it in close contact with the surface 250.
The pads 201 and 2011 rotate in a horizontal plane around the contact area between the pads 201 and 2010, and finally contact between the pads 201 and 2011 begins.

When the hook 4001 is held in a predetermined position, that is, a fixed position, the pads 201 and 2011 are in complete contact with each other, the positioning surfaces 2500 and 4010 are in complete surface contact, and the 90-degree surface 4002 and the 90-degree surface of the claw are brought into contact with each other. The two-surface contact between the two surfaces and the surface contact between the wiring board 300 and the positioning surface 4006 are simultaneously formed, and the holding of the cartridge IJC in the carriage is completed.

(iv) General description of the main body of the apparatus FIG. 6 shows an inkjet recording apparatus I to which the present invention is applied.
In the general view of JRA, the carriage HC that engages with the spiral groove 5004 of the lead screw 5005, which rotates via the drive force transmission gears 5011 and 5009 in conjunction with the forward and reverse rotation of the drive motor 5013, is a pin (not shown). ) and is moved back and forth in the directions of arrows a and b. Reference numeral 5002 denotes a paper holding plate that holds the paper on the platen 5 in the direction of carriage movement.
Press against 000. Reference numerals 5007 and 5008 are home position detection means for confirming the presence of the lever 5006 of the carriage in this area using a photocoupler and switching the rotational direction of the motor 5013. Reference numeral 5016 is a member that supports a cap member 5022 that caps the front surface of the recording head, and 5015 is a suction means for suctioning the inside of this cap to perform suction recovery of the recording head through an opening 5023 in the cap. 5017 is a cleaning blade, 5
Reference numeral 019 denotes a member that allows this blade to move in the front and back direction, and these are supported by a main body support plate 5018. Needless to say, the blade is not of this type, but a well-known cleaning blade can be applied to this example. Also, 5
012 is a lever for starting suction for suction recovery;
It moves with the movement of the cam 5020 that engages with the carriage, and the movement of the driving force from the drive motor is controlled by known transmission means such as clutch switching.

These catching, cleaning, and suction recovery are configured so that when the carriage reaches the home position side area, the desired processes can be performed at the corresponding positions by the action of the lead screw 5005. Any of these can be applied to this example as long as they are activated. Each of the configurations described above is an excellent invention whether viewed singly or in combination, and represents a preferable configuration example for the present invention.

In order to explain in detail the present invention technically related to the above-mentioned FIGS. 2 to 6, the following description will be made using FIGS. 1 and 7 and subsequent figures.

FIG. 7 is a developed perspective view showing an example of the packaging container of the present invention in use, FIG. 8 is a plan view of the container body, and FIG. 9 is a cross-sectional view of a portion of the container body and bottom plate in a joined state. FIG.

This packaging container is constructed using a container body 1 and a plate-like member (bottom plate) 3, which are integrated and used as a packaging container.

The container body l has an inkjet recording head (contents) 2
The wall C is maintained in a non-contact state with the interior (
It has a recess that protrudes toward the content storage area d), supports the content 2 accommodated therein, and fixes its position, and a flange b for integration with the bottom plate 3. code 1
0 indicates the ejection port of the inkjet cartridge 2. The discharge port 10 is maintained in a non-contact state with the wall portion in the storage space. Of the four corners of the storage space, if the corner where the outlet is located is made larger, the outlet can be better protected.

The wall portion C needs to have sufficient strength and is formed of such a material and thickness.

The thickness of the wall portion C may be appropriately selected depending on the type of its constituent material, but is, for example, 0.1 mm or more, preferably 0.1 mm or more, preferably 0.1 mm or more.
．． 3 mm or more, more preferably 0.5 mm or more,
The upper limit is, for example, 1.2 mm or less.

On the other hand, it is preferable that the recessed portion a has cushioning properties to buffer or absorb impact in order to protect the contents. That is, if the recess a is formed to have the same strength and rigidity as the wall C, the impact received by the wall C will be directly transmitted to the contents, causing damage to the contents.

From this point of view, it is desirable that the recess a be formed with a thin wall thickness and have elasticity.

The thickness of the concave portion a can also be selected as appropriate depending on its constituent material, but is, for example, 0.8 mm or less, preferably 0.8 mm or less.
．． 6 mm or less, more preferably 0.4 mm or less. Various resins can be used as the constituent material of the container body 1, and the container body 1 can be made in one piece or molded using resin or the like, for example.

The method of integral molding is suitable from the viewpoints of processability, production cost, etc.

Injection molding of various resins, vacuum molding, etc. can be used to manufacture the container body 1 in one piece. Among them, a method using vacuum forming using a sheet of resin such as polystyrene, ABS, polypropylene, polyethylene, polyethylene terephthalate, etc. is easy to adjust the thickness of the wall part C and the recessed part a, and can be done at low cost, and each part can be easily adjusted. This is suitable because desired properties can be easily imparted to the material.

On the other hand, by providing the flange b on the container body 1 as necessary, the container body 1 and the bottom plate 3 can be easily and reliably joined.

The flange b can also be molded simultaneously with other parts when the container body 1 is integrally molded.

The thickness of the flange b may be approximately the same as that of the wall portion C.

As shown in the figure, corners such as the concave portion a and the rising portion of the wall portion C may be provided as curved portions as necessary, thereby making it possible to improve the shock absorbing properties thereof.

The radius of the curved portion (Rl to R3, etc.) is preferably larger, and is appropriately selected depending on the size of the recess a, but is, for example, 2 mm or more, preferably 3 mm or more, more preferably 5 mm or more.
mm or more.

The shape of the recess a is appropriately selected so that the contents 2 can be effectively protected and positioned within the package.

In the illustrated example, the contents 2 are indicated by four recesses a, but the number of recesses can be changed as appropriate.

If the clearance between the indication part of the contents in the recess a and the contents is too large, it is not preferable because the contents may wobble or shift inside the packaging, but if it is too small, the contents will not be stored in the container body l. This is not preferable because it deteriorates the performance and the impact from the wall C becomes more easily transmitted. These clearances may be selected appropriately depending on the structure of the recess and the matching between the recess and the contents, but for example, 0.5 mm.
-3 mm, preferably about 0.5 mm - 2 mm.

The material and thickness of the bottom plate 3 are selected depending on the weight and strength of the contents, for example, resin film, paper sheet or board, etc.
A resin plate or the like is used.

If protecting the contents is important, for example, cardboard,
Paper with a wall thickness of 100 glrd or more is suitable because it has shock-absorbing properties, but if paper is the surface layer on the non-adhesive side to the container body (hereinafter referred to as the back side), environmental Under the influence of changes, particularly changes in humidity, paper may release or absorb moisture and curl and deform. Therefore, it is preferable to coat the back side with a moisture-proof layer of aluminum, vinylidene chloride, polypropylene, etc. to prevent deformation. or,
It is also possible to prevent force from being applied in the peeling direction to the adhesive portion between the container body and the bottom plate due to curling deformation. From the viewpoint of cost and strength, polypropylene having a thickness of 15 to 100 μm is most preferable for the moisture-proof layer.

In addition, by increasing the area of the bottom surface of the container body 1, when a packaged item is dropped, there is a high probability that it will fall from the wall side of the container body 1, and the shock-absorbing properties of the bottom plate can be improved to some extent.

Therefore, the area of the bottom surface of the container body l should be as large as possible within an allowable range.

Further, the same effect can be obtained by increasing the area of the bottom plate 3 to about twice the bottom surface of the container body 1, for example.

Various joining methods can be used to join the container body 1 and the bottom plate 3 after the contents 2 have been accommodated in the container body 1.

For example, the container body 1 and the bottom plate 3 can be formed of the same type of resin material and joined together by a method such as heat fusion or ultrasonic welding.

Further, an easy beer layer can be provided on at least the area necessary for bonding of the bottom plate 3, and this can be used to perform these bondings.

The method using the easy beer layer has the advantage that when unpacking, the bottom plate 3 can be easily removed from the packaging body 1, so there is no risk of damaging the contents.

For example, blister packs are made by strongly pressing together the vinyl chloride container body containing the contents and the mount having a vinyl chloride layer for bonding by melting the vinyl chloride parts together. This is a packaging material that is joined by
The package can be opened by destroying the mount or by making a perforation and destroying that part. In order to break the mount and open the package, strong force is often required, and the opening direction is unstable, which may damage the contents. Moreover,
Moisture resistance is generally not considered in blister bags.

Easy Beer is suitable when considering the humidity retention property of the contents such as moisture resistance and ease of opening.

As this easy beer layer, for example, layers made of various hot melt types, polyethylene types, EVAL types, etc. can be used.

In order to easily and reliably connect the container body 1 and the bottom plate 3, for example, a flange b as shown in the drawing may be provided at the bottom of the container body 1 as necessary.

On the other hand, by selecting the structural material of the packaging container of the present invention,
It is possible to maintain the humidity environment of the contents, that is, to obtain a moisture-proof function and a function to prevent moisture contained in the contents from evaporating to the outside.

For example, the above-mentioned humidity environment maintenance function can be obtained by using, in the structure of the container body 1, a material made of various resins coated with a vinylidene chloride layer or an aluminum layer, or a material that prevents moisture permeation, such as polypropylene. can.

Note that polypropylene is preferred from the viewpoint of manufacturing cost, moldability, processability, and the like.

At the same time, by using a resin film, sheet or board material, a paper sheet or board material coated with a vinylidene chloride layer or an aluminum layer, polypropylene that prevents moisture permeation, etc. for the structure of the bottom plate 3,
Good humidity environment maintenance function can be obtained.

In order to have a good impact buffering property and a humidity environment maintenance function, for example, the material should be made of paper or cardboard with an aluminum layer, and H (for example, an easy beer layer) for sealing the container body. ), and furthermore, a bottom plate having a polypropylene layer on the non-adhesive side (back side) to prevent curling is suitable. Among these, corrugated board having an aluminum layer and a polypropylene layer as the outermost layer on the non-adhesive side is more preferable in terms of cost, impact cushioning properties, and humidity environment maintenance function.

In addition, when using a vacuum mold using polypropylene to form the container body, as mentioned above, the recess a and the wall C
It is preferable to mold the rising portion of the container as a curved portion in order to improve the shock-absorbing properties of the container body 1 and to provide the container body with the above-mentioned humidity environment maintenance function.

Furthermore, from the ceiling C-2 of the container body 1 to the bottom (flange b)
According to male molding, in which the parts other than the part that will become the ceiling part c-2 of the raw material sheet are stretched in a vacuum to form the concave part a5, the side face c-1 of the wall part C, the curved part, etc., the thickness of each part is This is preferable in terms of improving the uniformity of the film, preventing the occurrence of pinholes, and increasing the prevention of hot air permeation in various parts.

In addition, if a curved part is not provided in the container body obtained by vacuum molding, the boundaries between the wall of the container body and the recess, and the boundaries between the wall and the flange, etc., will be formed as corners with thin walls, resulting in bottle holes. It is easy to use, and is also prone to damage when dropped.
The moisture permeation prevention property of that part decreases.

On the other hand, by forming these boundaries as curved portions, the thin walled portions are prevented from being distorted, and good moisture permeation prevention properties can be uniformly obtained over the entire container body. The outer periphery is strong against drop impacts.

Furthermore, if a transparent or translucent material is selected for the container body l and/or the bottom plate 3, the contents 2 can be seen through in the packaged state.

Additionally, by providing a covering member to cover (seal) the ejection port on the ejection port surface of the inkjet cartridge, evaporation of ink from the ejection port can be extremely reduced, making it possible to maintain appropriate humidity in the storage space. Therefore, curling deformation of the bottom plate can be almost prevented, and
The condition of the ink supply path from the ink tank to the ejection port can be maintained in a good condition.

The covering member according to the present invention is not limited to the tape-like member described above, but it is easy to handle (for example, it is easy to peel off) and is excellent in maintaining an airtight state of the discharge port. A tape-shaped material is most suitable because it is thin, has little effect on the size of the inkjet cartridge, and can be formed at relatively low cost.

(Leaving space below) Example 1 A container body having the structure shown in FIG. 7 was made using a sheet of polypropylene with a thickness of 1 mm, and the material part other than the ceiling part c-1 was stretched toward the bottom part. It was manufactured by vacuum forming a male type.

The sizes of each part are as follows.

Minimum wall thickness: 0.2 mm R1 to R3: 3 mm On the other hand, as shown in Fig. 10, in the E cardboard 3a,
polyethylene terephthalate layer 3b (thickness 12 μm),
An aluminum layer 3c (thickness 9 μm) and a polyethylene easy beer layer 3d (thickness 30 LLm) are provided in this order on the adhesive side to the container body, and a polypropylene layer 3e (thickness 30 μm) is provided on the non-adhesive side. 2 of the container body.
The bottom plate 3 was produced by cutting into a rectangular shape with a double cross-sectional line. The area of the bottom plate 3 is approximately 2 of the bottom surface of the container body 1.
It was doubled.

Next, the inkjet recording head (in this example, an inkjet cartridge including an ink tank) (200 g) 2 filled with ink is stored in the container body 1, and the bottom plate 3 is aligned with the bottom of the container body, and the flange b and the bottom plate 3 are aligned. were adhered using an ultrasonic welding machine.

When the resulting package was dropped onto a concrete floor 10 times from a height of 95 cm and the protective state of the packed recording head was inspected, no damage was found to the recording head.

Furthermore, when a similar drop test was conducted using this package as a collective package of 20 pieces, no abnormality was found in each recording head.

Furthermore, after leaving the resulting package in a dry atmosphere at 60°C for one week, the amount of water evaporated from the ink filled in the recording head was examined by measuring the weight of the recording head. , a weight loss corresponding to 0.14 g of water evaporation was measured.

Moreover, no deformation such as curling of the bottom plate was observed after being left for one week.

Example 2 A container body was prepared in the same manner as in Example 1, except that a vinyl chloride sheet coated with vinylidene chloride having a thickness of 30 μm was used, and an inkjet recording head was packed.

When the resulting package was subjected to a drop test in the same manner as in Example 1, no abnormality such as damage occurred to the packaged recording head.

Further, when the amount of water evaporated from the ink of the packed recording head was measured in the same manner as in Example 1, O. The weight was 17g, and no deformation such as curling of the bottom plate was observed.

Example 3 A container body was produced in the same manner as in Example 1 except that the radius R of each curved portion was 1 mm, an inkjet recording head was packed, and a drop test and the amount of water evaporation were performed.

In addition, the minimum thickness of the obtained container body is 0.05
It was mm.

As a result, in the drop test, dents and holes were found in the container body of the package, but there were no abnormalities in the packaged recording head.

Further, the amount of moisture evaporated from the recording head was 0.25 g, and no deformation of the bottom plate was observed.

Example 4 A container body is molded by female molding in which the other parts (recess a and wall C) are pulled and molded by vacuum from the part that will become flange b in a polypropylene sheet, and R3=0. The inkjet recording head was packed in the same manner as in Example 1 except that the radius of curvature of the other corners was 2 mm.

The obtained package was subjected to the same drop test as in Example 1 and the amount of water evaporated from the ink was measured.

In the drop test, there was no abnormality in the packaged recording head.

The amount of moisture evaporated from the ink was 0.33 g, and no deformation of the bottom plate was observed.

Example 5 Among the plurality of layers forming the bottom plate, instead of using the bottom plate in which the polypropylene layer 3e of FIG. 10 is not provided,
As shown in FIG. 1, a protective tape 9 serves as a covering member to seal the ejection port 10 on the ejection port surface of the inkjet cartridge 2.
The inkjet cartridge was housed in the same manner as in Example 1, except for providing the inkjet cartridge. The results of the performance tests regarding the obtained storage containers showed that among the many storage containers, there were a few cases where the edges of the bottom plates were curled, but this did not really pose a problem, and ink leaked from the ejection port. The results were almost the same as in Example I, except that the evaporation of was extremely low.

Example 6 Among the multiple layers forming the bottom plate, Example 1 was used except that a protective tape 9 was provided on the ejection port surface of the inkjet cartridge 2 as a covering member to seal the ejection port 10 as shown in FIG. I stored the inkjet cartridge in the same way. The results of the performance test regarding the obtained storage container were almost the same as in Example 1, except that the evaporation of ink from the ejection port was extremely small.

Comparative Example 1 A container body was produced in the same manner as in Example 1, except that no recess was provided in the container body, no polypropylene layer was provided on the non-adhesive surface (back surface) of the bottom plate, and the surface layer was made of E cardboard 3a.
Packed the inkjet recording head.

The resulting package was subjected to a drop test and the amount of water evaporated from the ink was measured. In the drop test, the recording head had severe play within the package, and the impact of the collision with the floor caused ink leakage and damage to the recording head, making it unusable.

Also, the amount of moisture evaporated from the recording head was 0 as in Example 1.
．． The weight was equivalent to 14 g, but after being left for one week at 60° C. in a dry atmosphere, some of the bottom plates were curled toward the non-adhesive side (back side).

Comparative Example 2 Inkjet recording head filled with ink (2
0 0 g) into a vacuum-formed container, put a lid on it, and then put it into an aluminum container with a wall thickness of 0.1 mm.
The opening was covered with a film 1 having a thickness of 50 ILm having an adhesive layer, and the product was packed in an individual box.

After performing the same drop test as in Example 1 using the obtained package alone, the condition of the recording head was observed.
There were no abnormalities. However, in drop tests when aluminum containers are not stored in individual boxes or when they are packaged in units of 100, there is a 1-2% chance that the aluminum containers will be deformed or bottle holes will occur due to damage. The percentage was When the aluminum container of the package was deformed or a bottle hole was generated due to damage, its moisture permeation prevention properties became poor.

When the cost for packaging in this comparative example was compared with the packaging cost in the method of Example 1, the packaging cost in this comparative example was about twice the cost in Example 1.

In addition, the work of opening the package obtained in this comparative example was extremely complicated compared to the work of opening the package in Example 1, and it took about 30 minutes to open the package.
It took twice as long.

Further, in the packaging of Example 1, the condition inside the package could be seen through, but in the packaging of this comparative example, the condition inside the package could not be seen through.

Furthermore, in the case of the packaging method of this comparative example, the number of parts is large, making it difficult to automate the packaging. It is difficult to directly incorporate the packaging process, and it is necessary to set up a separate line for the packaging process. According to the inventors' calculations, when adopting the packaging process using the packaging method of this comparative example, approximately 1.5 times as much capital investment is required as when, for example, the packaging method of Example 1 is directly incorporated into an automatic production line. becomes.

Comparative Example 3 A drop test similar to Example 1 and measurement of the amount of water evaporation from the ink were conducted using a normal blister bag type configuration.

In other words, the container body simply matches the shape of the recording head,
The mount is coated with a layer of vinyl chloride and weighs 100 g.
Zrd corrugated paper was used.

In a single drop test, a large amount of ink was scattered inside the package due to the impact of dropping and hitting the floor.

Further, the amount of moisture evaporated was 1.8 g, and after being left for one week under dry conditions at 60° C., the mount was curled toward the non-adhesive side.

Comparative Example 4 An inkjet recording head was placed in an aluminum bag, tightly pierced, and then stored in an individual box with tape for packaging.

After performing the same drop test as in Example 1 on the obtained package, we observed the condition of the package.We found that the aluminum bag was damaged and there were holes in the bottle, and there was a large amount of ink scattering, indicating that the recording head was not used. It became impossible.

Comparative Example 5 An inkjet recording head was placed in an aluminum bag and sealed, the sides were further protected with foamed polystyrene, and the bag was placed in an individual box and packed with tape.

A drop test was performed on the resulting package and the amount of water evaporated from the ink was measured.

The protection of the recording head and the prevention of moisture permeation in this package were good.

However, the volume of the entire package was approximately three times that of the package in Example 1, and the space occupied during transportation and storage increased.

Furthermore, when the packaging cost in Example 1 and the packaging cost in this comparative example were compared, they reached about three times as much.

Comparative Example 6 An inkjet recording head was placed in an aluminum bag and sealed, further wrapped in an air pack, and stored and packaged in an individual box with tape.

A drop test was performed on the resulting package and the amount of water evaporated from the ink was measured.

In the drop test, ink leakage was observed, but the moisture permeation prevention property was good.

The volume of the entire package is about 1.
This has increased five times, and the space occupied during transportation and storage has increased.

Furthermore, the packaging work in this comparative example is difficult to automate and requires manpower, and when the packaging cost in Example 1 was compared with the packaging cost in this comparative example, it reached approximately twice.

The present invention provides excellent effects particularly in bubble jet recording heads and recording apparatuses among ink jet recording systems.

As for typical configurations and principles thereof, it is preferable to use the basic principles disclosed in, for example, US Pat. No. 4,723,129 and US Pat. No. 4,740,796. This method can be applied to both the so-called on-demand type and continuous type, but especially in the case of the on-demand type, the ink is placed in correspondence with the sheet holding the liquid (ink) and the liquid path. In the electrothermal converter,
By applying at least one drive signal corresponding to recorded information and providing a rapid temperature rise exceeding nucleate boiling, the electrothermal transducer generates thermal energy to cause film boiling on the thermally active surface of the recording head. As a result, bubbles in the liquid (ink) can be formed in one-to-one correspondence with this drive signal, which is effective. The growth and contraction of the bubble causes liquid (ink) to be ejected through the ejection opening to form at least one drop. It is more preferable to use this drive signal in a pulse form, since the growth and contraction of bubbles can be carried out immediately and appropriately, making it possible to eject liquid (ink) with particularly excellent responsiveness. As this pulse-shaped drive signal, those described in US Pat. No. 4,463,359 and US Pat. No. 4,345,262 are suitable. Incidentally, U.S. Patent No. 4313 relates to the temperature increase rate of the heat acting surface.
If the conditions described in the specification of No. 124 are adopted, even more excellent recording can be performed.

The configuration of the recording head includes, in addition to the combined configuration of ejection ports, liquid paths, and electrothermal converters (straight liquid flow path or right-angled liquid flow path) as disclosed in the above-mentioned specifications, a heat acting section. US Pat. No. 4,558,333 and US Pat. No. 4,459,600 disclose a configuration in which the
The present invention also includes a configuration using the specification of the above specification.

In addition, Japanese Patent Application Laid-Open No. 123670 of 1982 discloses a configuration in which a common slit is used as a discharge part for a plurality of electrothermal converters, and an open source for absorbing pressure waves of thermal energy is disclosed. The present invention is also effective with a configuration based on Japanese Patent Application Laid-Open No. 138461 of 1982, which discloses a configuration in which holes correspond to discharge portions.

Furthermore, as a full-line type recording head having a length corresponding to the width of the maximum recording medium that can be recorded by the recording apparatus, the length can be increased by combining multiple recording heads as disclosed in the above-mentioned specification. Either a configuration that satisfies the above requirements or a configuration as a single recording head formed integrally may be used, but the present invention can more effectively exhibit the above-mentioned effects.

In addition, a replaceable chip-type recording head that is attached to the device body enables electrical connection to the device body and ink supply from the device body, or a chip-type recording head that is installed integrally with the recording head itself. The present invention is also effective when a cartridge type recording head is used.

Further, it is preferable to add recovery means, preliminary auxiliary means, etc. for the recording head, which are provided as a configuration of the recording apparatus of the present invention, because the effects of the present invention can be further stabilized. Specifically, these include preheating means for the recording head by means of a caving means, a cleaning means, a pressurizing or absorbing means, an electrothermal converter or another heating element, or a combination thereof. It is also effective to perform a preliminary ejection mode in which ejection is performed separately from printing in order to perform stable printing.

Furthermore, the recording mode of the recording device is not limited to a recording mode in which only the mainstream color such as black is used; the recording head may be configured integrally or in combination with a plurality of recording heads; The present invention is also extremely effective for devices equipped with at least one full color image.

[Effects of the Invention] By using the packaging container of the present invention, the inkjet recording head, which is easily damaged, can be reliably and inexpensively protected from shocks caused by vibrations and drops during transportation and the like.

The packaging container of the present invention is provided with a recess that is arranged according to the shape of the contents, supports the contents at appropriate intervals, and prevents the contents from coming into direct contact with the wall of the main body of the packaging container. Therefore, the contents can be effectively fixed in position within the package, and impact applied to the main body wall portion from the outside can be prevented from being applied to the contents.

Furthermore, packaging using the packaging container of the present invention has a small increase in space occupied by packaging, is highly space-saving, and can save warehouse space and distribution space.
Costs in storage and logistics can be reduced.

Further, the packaging container of the present invention can be provided with a function of maintaining the humidity environment while the contents are packed, and it is possible to provide packaging that not only protects the contents but also maintains the humidity environment. In particular, by making the surface layer of the non-adhesive surface (back surface) of the bottom plate a moisture-proof layer, curling deformation of the bottom plate can be prevented, and at the same time, the protection and strength of the surface layer of the bottom plate can be improved.

In addition, by providing a nitrogen member on the ejection port surface of the inkjet cartridge to cover (seal) the ejection port, evaporation of ink from the ejection port can be extremely reduced, making it possible to maintain appropriate humidity in the storage space. Therefore, curling deformation of the bottom plate can be almost prevented, and
The condition of the ink supply path from the ink tank to the ejection port can be maintained in a good condition.
