Abstract

PURPOSE:To accomplish a reliable protection function against an external impact by separating a function for containing contents in a closed state from a function for holding a package for accomplishing the containing function. CONSTITUTION:A holding member 104 comprises an open area 102, a folded plane area 103, and an indication area 105, which are formed by a sheet member. A flange part 61b of a package 101 is held by folding the holding member 104 in two so that the folded plane area 103 is disposed on a cover member 63 of the package 101 inserted into an open part 102a of the open area 102. In this manner, the package 101 is securely held, and the package 101 is prevented from slipping off. In addition, a cut line part 111 to be opened is provided on the top surface on which the open part 102a is formed. Therefore, if an external impact is applied to the package 101, a stress to be applied to the cutting line 111 to be opened is remarkably small, and the breakage of the cut line part 111 is prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a storage container suitable for packaging inkjet cartridges, which are objects to be stored that are undesirable from shocks due to vibrations, drops, etc., and a storage container used for holding the same. The present invention relates to an inkjet cartridge package comprising: a holding member;

[Background technology]

Conventionally, packaging containers that combine the function of packaging and protecting easily damaged items have been made of packaging materials with shock-absorbing properties, such as paper, cardboard, foam sheets, and resin molded products such as styrofoam and polyurethane. has been used.

[Problems to be Solved by the Invention] However, in packaging containers using cardboard boxes, for example, the cardboard itself does not necessarily have sufficient local strength, and is easily dented or damaged by local external forces. If the sizes of the packaging and the cardboard do not match, localized force may be applied to the packaging due to dropping or vibration impact.
Not only was the packaging damaged, but the stored items could also be deformed or damaged.

Similarly to cardboard boxes, when packaging materials such as paper, resin, or wood are used, for example, if the sizes of the storage container and the items to be stored do not match, the items to be stored may dance around inside the box during transportation. The impact may cause some kind of damage to the stored items.

On the other hand, there is a case where a resin material or a sheet material made of the resin material and air bubbles is used as a shock absorbing material and is wrapped around the stored item for packaging. In this form, a somewhat satisfactory result can be obtained from the viewpoint of protecting the stored items. However, wrapping the sheet material around the items to be stored complicates the packaging operation, increases the volume of the items to be stored, increases the need for external packaging materials, and increases the cost. Even when materials are used, the protection function is not always satisfactory for stored items that are composed of complex irregularities. There is a packaging container that uses a foamed resin molded product as a shock-absorbing material in packaging. These packaging containers are easy to mold to match the shape of the items to be stored, and have good shock-absorbing properties, so they are extremely effective at fixing the position of items to be stored within the packaging container and protecting them. expensive.

However, in order to obtain sufficient shock-absorbing properties in a foamed polystyrene molded product, the wall thickness must be increased, resulting in an increase in the volume of the packaging container. (For example, the volume of a storage container made of styrofoam molding is usually 2 to 3 times that of a packaging container made only of cardboard boxes.6) Such a significant increase in the amount of space it occupies has an impact on warehouse space and logistics costs. It becomes a big burden.

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 recommended to insert a sleeve-shaped cardboard sheet over the Styrofoam case or cover it with cardboard. and
Packaging costs are also high.

In addition, a combination of a molded vinyl chloride container body such as a blister pack, a layer of vinyl chloride at the adhesive part of the container body, and thick paper that is adhered to the container body as a bottom plate. There is a packaging container.

This packaging container 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 often used for items that have high strength and are difficult to break or deform, or for stored items that will cause little damage even if they are broken.

As mentioned above, it is currently difficult to find a packaging container that satisfies all requirements such as protection of stored items, space occupied by the packaging container, and packaging costs.

Furthermore, packaging containers must not only be resistant to external shocks in order to protect the items stored inside them, but also environmental measures such as protecting items from environmental changes such as humidity are extremely important issues. be.

For example, the items to be stored are placed in a bag made of a thin aluminum film to prevent moisture, sealed, and then stored in the above-mentioned packaging container, or stored in a strong case made of aluminum plate along with various shock absorbing materials. There is.

However, in either case, the cost of materials required for packaging is high, and the protective function is often insufficient. Moreover, it has the disadvantage that the 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.

Therefore, in the development stage of the packaging container, the present inventor solved the problems with the conventional packaging materials mentioned above, and satisfied the requirements regarding protection of stored items, space occupied by the packaging container, cost of packaging, etc. Inkjet head cartridge storage container that can maintain the humidity environment of stored items (
packaging containers).

This inkjet head cartridge storage container is
Equipped with storage space for inkjet head cartridges,
a container body having a wall portion maintained in a non-contact state with the inkjet head cartridge; and a recess portion protruding from the wall portion into the storage space to contact and support the inkjet cartridge; A plate-like member that is directly joined to seal the container body.

That is, since the container body and the plate-like member are directly joined, the plate-like member serves both as a lid for the container body and as a support member for the storage container.

Providing the plate-like member with two functions, the lid function and the support member function, has the advantage of simplifying the structure. However, since the container body and the plate-like member are directly and closely joined, for example, when the container collides with another item or falls, the impact may cause the 88 kibushi and the plate-like member to separate. there were. In this case, the reliability of the packaging deteriorates, and in particular, the predetermined environment inside the storage container cannot be maintained due to peeling of the container body and the plate-like member.

Therefore, in order to prevent the container body and the plate-like member from peeling off even if the container body and the plate-like member are collided or dropped, it is conceivable to bond them together very firmly.

However, if the container body and the plate-shaped member are bonded very strongly, it may be difficult to peel them off properly during the opening operation when removing the inkjet head cartridge stored in the packaging container. was there. That is, even if both are peeled off, a part of the material forming the integral surface side of the plate-like member remains in the container body, and it may not be possible to actually open the container.

The present invention achieves a thick protection function against external impact by separating the storage function for sealing storage of stored items and the holding function for holding the storage container that achieves the storage function. The purpose of t7P is to provide a package for inkjet cartridges that can be used as an inkjet cartridge.

[Means for Solving the Problems] The present invention has been proposed to achieve the above-mentioned object, and comprises: a storage section for storing an inkjet cartridge; a storage section integrally formed with the storage section; , a lid member integrally formed with the storage part to form a sealed space with the storage part; and the storage part of the storage container with an opening larger than an outer edge of the storage part of the storage container. a holding member that integrally includes an opening end larger than the outer edge of the opening, an opening area having a peripheral part of the opening end and an opening notch, and a folded flat area facing the opening area. The peripheral portion and the corresponding folded flat area are joined together, and the storage portion is held between the open end portion and the folded flat area corresponding thereto.

Further, the constituent elements include a storage section for storing an inkjet cartridge, a storage section integrally formed with the storage section, and a lid member integrally formed with the storage section to form a sealed space with the storage section. an opening area having an opening larger than the outer edge of the storage part of the storage container, an opening end larger than the outer edge of the storage part of the storage container, a peripheral part of the opening end, and an opening slit. and a holding member that integrally includes a folded flat area facing the opening area, and a display member having a hook portion for hooking when displaying the inkjet cartridge. Preferably, when the inkjet cartridge package is in a hooked state, the inkjet cartridge is housed in the storage container such that the head portion of the inkjet cartridge is positioned downward with respect to the direction of gravity.

[Effect]

By creating a package with a separate structure, the storage function for sealing storage of inkjet cartridges that are stored and the holding function for holding the storage container that achieves the storage function are effective against external shocks. It becomes possible to achieve a high level of protection function.

Furthermore, since the storage portion of the storage container is sandwiched and fixed between two opposing surfaces of the sheet member, the storage container can be held securely.

Furthermore, a notch for taking out the storage container from the holding member is formed on the surface side of the holding area of the storage container, and a display area is provided in an area different from this, so it is easy to see how to take out or handle labels and stored items. Displays such as the following can be written effectively.

Furthermore, when attaching the storage container to the holding member, the head of the inkjet cartridge is positioned downward relative to the direction of gravity when displayed, so the ink present in the head may retreat from the ejection port. This effectively prevents air (bubbles) from entering the head from the discharge port.

[Example] Hereinafter, embodiments to which the present invention is applied will be described in detail with reference to the drawings.

The inkjet cartridge package according to the present invention is shown in FIG. 1 or FIG. 20(a) to FIG. 20(
It has the configuration shown in d).

That is, the inkjet cartridge package includes a container main body 61 that is a storage section in which an inkjet cartridge can be stored, and a storage section 61 that is an area where a lid member 63 for making this container main body 61 into a sealed space is joined.
b, an opening 102a that is larger than the outer edge of the container body 61 of the storage container 101 and into which the container body 61 can be inserted, an opening end 102b larger than the outer edge of the storage part 61b, and an end. Peripheral part 10 of 102b
Opening area 102 with 2C and opening notch 11
1, the folded flat area 103 is disposed facing the opening area and holds the storage portion 61b in cooperation with the opening area 102.
and a holding member 104 including.

Here, the inkjet cartridge IJC stored in the storage container 101 has a configuration as shown in FIG. The press member includes a sheet member and an elastic body for pressing the sheet member.

13(a) and 13(b) are explanatory diagrams of one configuration example of an inkjet cartridge IJC, showing a perspective view and a partially exploded view thereof in order, and FIGS. 2(a) and 2(b) are illustrations of a configuration example of an inkjet cartridge IJC. This is a partial explanatory diagram of an example, showing a top view and a side view in order, and Figure 3 (
a), (b) and FIG. 4 (a), (b) are explanatory diagrams of a modified embodiment of FIG. 2, respectively, showing a top view and a side view in that order, and FIG. 5 is a diagram showing another embodiment of the present invention. Partial exploded view of the example, Figure 6 is the 5th
Figure 7(a), (
b), (C), and Figure 8 (a), (b), (c) and Figure 9.
Figures (a), (b), and (C) are explanatory diagrams of still another embodiment of the present invention, showing a side view, a front view, and a top view, respectively, and Figures 10 and 11. 12 is a perspective view of an embodiment of the present invention in which the recording head configuration is further modified, and FIG. 12 is a partially sectional explanatory view illustrating the configuration for attaching and detaching the recording head of this embodiment to and from the main body of the recording apparatus. In Fig. 13, IJC is an inkjet cartridge, which has an ink absorber built into the ink storage part, and a supply pipe that communicates with it.
A recording head to which ink is supplied (a thermal energy generator 91 shown in FIG. 5, a substrate 100 on which an electrode 92 is formed,
An orifice plate 400 having a plurality of discharge ports 41 is provided. In this embodiment, a top plate 1300 for forming a liquid path 140 and a plate 400 are integrally molded. ) shows a recording head that is removable from the recording apparatus main body, which is integrally fixed thereto. S is an opening that can monitor an electrical connection section, which will be described later, and is provided on the upper surface of the recording head. Reference numeral 10 denotes a base plate of the substrate of the recording head, which is an aluminum plate in which a positioning portion 8 for positioning the entire recording head by engaging with the positioning portion 4010 of the carriage of the recording apparatus main body shown in FIG. 12 is integrally formed. It is. Reference numeral 1 indicates the surface of the ejection portion including the orifice plate, and numeral 41 indicates the recording ink ejection portion. In this embodiment, openings for absorbing back waves during recording and openings such as dummy nozzles are not disclosed, but hereinafter, even if these are included, they can be regarded as the ejection part surface 1. Reference numeral 2 denotes grooves provided on the upper and lower surfaces recessed from the discharge part surface l, and in this example, four grooves are formed as shown in the figure. Reference numeral 53 denotes a side groove section which is located on the side surface facing the base plate 10 and has four grooves that are continuous to the grooves of the groove section 2. When a large amount of ink is accumulated in the groove section 2 due to ink scattering, this side groove section is provided. It is possible to achieve the effect of guiding the material downward. This recording head groove portion 2 receives an elastic pressing force from the groove portion 51 of the cap 4 to maintain the engaged state.

Reference numeral 3 denotes a sealing sheet, which has a size that completely covers the ejection portion surface 1 of the recording head, and has a portion that protrudes outward from the end of the recording head as shown in FIG. 2(a). There is.

This protrusion becomes a brim when the seal is peeled off from the recording head. The sheet 3 is attached to the recording head as shown in FIG. 1(a) by interposing an adhesive between the sheet 3 and the ejection portion surface 1 to form a simple adhesive state.

13. The cap 4 has a width corresponding to the discharge part surface 1, and has two opposing arm parts 5.5, an elastic body 6 separated from the arm parts and fixed to the inner surface of the main body, and a base plate 10 side. It is integrally provided with a positioning or elastic deformation regulating portion 7 provided on the side of the main body, and a collar 9.9 that can be used when attaching and detaching the cap 4 itself to the recording head. The arm portions 5.5 each have three grooves 51 on their inner surfaces that engage with the grooves 2.

In this embodiment, as can be seen in FIGS. 2(a) and 2(b), the seal 3 is extended onto the base plate 10, and at the same time, the elastic body 6 is provided on the base plate 10 so as to face it. This is a configuration for further improving the sealing effect since the discharge port 41 is close to the base plate 10. The portion 7 has a length slightly larger than the back side of the base plate 10 when the cap 4 is attached to the recording head. This contact length is approximately 1 mm in this example. Due to this slight configuration, the elastic body 6 of the cap can consequently be aligned with the arm 5.5 and the positioning part 7.
Thus, the base plate 10 is reliably positioned within the sandwiching range. In other words, with a simple configuration, the effect of sealing the opening can be achieved without causing the above-mentioned problems with adhesives.

3(a) and 3(b) show a configuration in which the pressing area of the elastic body is concentrated on the discharge port, and for this purpose, the portion facing the base plate 10 in the configuration of the elastic body 6 in FIG. 2 is removed. There is. Further, in this embodiment, one portion 7.7 is made to function as a portion for regulating the amount of elastic deformation, and with this configuration, the entire discharge port can be sealed with a uniform pressure distribution, so this is one of the preferred embodiments. The configuration other than the above in Figure 3 is as follows:
It is similar to Figure 1.2.

4(a) and 4(b) show a configuration in which the portion 7.7 in FIG. 2 is further extended to have a function as a guide when attaching the cap member 4 to the recording head. In this embodiment, since the arm portion 5.5 has the same length, when the cap is attached, the portion 7.7 must be securely positioned on the back side of the base plate 10 in order to attach the cap. It has been made smaller and the operability when installing it has been further improved.

To briefly explain the engagement state of the groove portions 2.51 in the above embodiment, when the collar portions 9.9 are moved inward when worn, the arm portions 5.5 are elastically deformed to widen the distance between them. In this state, engagement of the groove portions 21.51 can be achieved by positioning the recording head between the arms 5.5 of the cap and separating the collar portions. At this time, even if the positional deviation occurs by one groove,
By setting the depth of the groove to 1 mm or less, the elastic pressing force of the arm and the elastic force due to deformation of the elastic body 6 can be easily balanced. In this state, if the same number of upper and lower grooves are engaged, the overall balance will be optimized, the sealing will be strong, and the pressure distribution will also be optimized, ensuring sealing. Ru. The elastic material of the elastic body 6,
Any thickness can be used as long as it can press the sheet 3 and maintain the sealing force when the grooves 2.51 are engaged.

The specific structure of this embodiment is that the sheet 3 is made of polyethylene terephthalate, 4-helical ethylene, etc., with a thickness of 12 to
The flexible sheet has a thickness of about 30 μm, and the elastic body is a sponge with a thickness of about 3 mm, such as a silicone sponge or a polyurethane sponge. It goes without saying that the present invention is not limited to the above configuration.

FIG. 5.6 shows an example of a discharge section in which a step with a height of about 30 μm is formed on the upper and lower surfaces of a step forming surface G of about 70 μm. The present invention can form a reliable sealed state even on such a step-shaped surface.

The ink receiver has a region Z that spreads toward the part side, and the ink receiver has a slope 21 extending from the part toward the region, and the ejection energy generating means of the liquid path in which the extension line of the slope faces the region It has reached the surface position P0 of the substrate 8, which is the side surface where H is arranged. In this embodiment, the slope 21 is at an angle of 22 degrees with respect to the center line C2 of the ink channel and the extension line of the ink channel, and the angle B of the left and right inner wall surfaces is 15 degrees.

Due to the existence of this expanding region Z, the microbubbles are not only aggregated here, but also the aggregated bubbles are retained in a region away from the extension of the liquid path where the discharge energy generation means H is located. Even if the size is increased, the bubbles are guided in a direction away from the liquid path along the slope, thereby significantly delaying the occurrence of recording defects. Moreover, the extension line of the slope reaches the side surface of the liquid path where the discharge energy generating means is arranged, which faces the area.

Even if air bubbles existing due to impact try to enter the liquid path along the slope, large air bubbles will not enter the ejection energy source and cause recording defects. This inkjet recording head is not limited to the above angle. It is clear from the above description that if the angle limitation described above is added to this configuration, the effect will be further improved.

The configuration described below is particularly effective for suction recovery, but also discloses a configuration that is also effective for pressure recovery. Reference numeral 141 indicates an isosceles trapezoidal shape of the opening at the side end of the orifice plate of the liquid path, 111 indicates an isosceles trapezoidal shape of the inner opening of the orifice plate in contact with this, and the discharge portion also indicates an isosceles trapezoidal shape. There is.

In this embodiment, the ink transport path from the liquid path to the discharge section has an isosceles trapezoidal cross-sectional shape. In other words, if the liquid path has a trapezoidal cross-section with the base facing the discharge energy generating means side, the conditions for dispersion of bubbles over the entire inner surface of the liquid path can be made uneven, so that bubbles can be generated or invaded. In addition to concentrating the bubbles on the short side of this trapezoidal shape, the bubble discharge route during recovery can be concentrated, so that the bubble discharge effect can be further improved. Further, the discharge part corresponding to the liquid path having the trapezoidal cross section has a short side of the liquid path having the trapezoidal cross section as the short side,
According to the trapezoidal configuration with the long side as the long side, 1
9. Occurrence of ink turbulence during recovery can be prevented and the bubble discharge effect can be stabilized. Furthermore, it is even more preferable that this shape is an isosceles trapezoid. In this example, the most preferable shape is the first one in which the liquid path expands in the vicinity of the discharge part of the liquid path while remaining in the shape of an isosceles trapezoid.
Area (liquid path from line P+ to opening 141.111)
and a second region (from opening 11 to opening 11) which is narrower than this liquid path and connected to the isosceles trapezoid-shaped ejection portion while remaining in an isosceles trapezoid shape, so that the ink can be Air bubbles can be reliably removed with almost no turbulence.

Furthermore, in this embodiment, the surface (line CI) formed by connecting the centers of the legs of the isosceles trapezoid cross section of the liquid path on the sixth drawing.
Regarding this, since the above-mentioned region 1.2 is symmetrical, the pressure distribution applied during recovery can be made uniform, and the occurrence of minute turbulence in the discharge region can be significantly reduced. Note that since the extension of the line C1 reaches the point P on the surface of the heat generating element H, the ejection energy is efficiently used for ejection.

Further, according to the present invention, the top plate member forming the common liquid chamber and the discharge part forming member are integrated, and the liquid path forming member has a stepped portion for engaging with the substrate, and the liquid path forming member A pressurizing member applies linear pressure from above the liquid passages in the arrangement direction of the liquid passages and holds the top end of the substrate under pressure in a state where it is engaged with the stepped portion. However, it is possible to perform excellent recording without the above-mentioned disadvantages caused by the generation of bubbles.

In this embodiment, the orifice plate is formed of OPI, OF2, and OF3 at different angles (deviation point H1I), and the ejection direction of droplets is constant in the extending direction of the line C1, so the recording surface is formed along the line C1. The plane is perpendicular to CI. In this example, the recording medium moves from the bottom to the top of the page. The orifice plate has a stepped side cross-sectional shape with a gentle slope on the side where the discharge part is provided, so it can be cleaned during wiping without installing special parts inside or outside the cap. In addition to further improving reliability, the effect of preventing the ink meniscus from receding at the ejection section during capping is also improved, and therefore ink ejection failure and various problems derived from it can be better solved with a simple configuration. be able to.

The height of the region Z in FIG. 6 is preferably the same as or smaller than the height of the liquid path, and the angle θ2 in the diagram formed by the region Z is 10 degrees, and the angle of the slope 21 is It is preferably less than half of θ1.

As can be seen in Fig. 6, the surface of the discharge port and its surrounding surface are
The sheet 3 is securely sealed, and this state is maintained by the elastic body 6.
Since it is maintained in a state of elastic deformation, it can exhibit better effects than conventional ones.

The embodiment in FIG. 7 has a configuration in which the portions 7 and 7 of the embodiment in FIG. 2 are omitted.

Therefore, the elastic body 6 that presses against the base plate 10
The portion of the cap is pressed securely by the extension portion 41 of the cap body. This simplifies the cap member and allows the cap to be attached to and removed from the recording head by using the groove 5.
There is also the advantage that it can be done by sliding along 1.

In FIG. 8, the above-mentioned cap structure is adapted to engage with the positioning portion 8.8 of the base plate 10 and the groove portion 53, and the seal 3 is provided only inside the cap. This configuration is an example in which the positioning accuracy of the recording head with respect to the recording apparatus is utilized to improve the actual mounting accuracy.

The embodiment shown in FIG. 9 is an embodiment in which the width of the cap of the embodiment shown in FIG. 2 is expanded to cover the entire front surface of the recording head including the ejection section surface 1 of the recording head, thereby making the mounting state more stable.

Fig. 10 shows an embodiment in which parts 7 and 7 of the above Fig. 9 embodiment have been removed.With this size, there is no need to add a structure for accurate positioning, and it can be mounted in accordance with the recording head. By simply doing this, you can easily achieve a stable attachment state.

FIG. 11 discloses a cap member in which the seal 3 is integrated with the surface of the elastic body of the cap, a recording head using the same, and a method for storing the same.
This configuration is effective for the recording head itself after being taken out from the carriage of the configuration disclosed in the figure.

As can be seen from the perspective view of FIG. 12, the IJC has a large ink storage ratio, and has a shape in which the tip of the inkjet unit slightly protrudes from the front surface of the ink tank.

The inkjet cartridge IJC is a disposable type that is fixedly supported by a positioning means and electrical contacts, which will be described later, on a carriage HC placed on the inkjet recording apparatus main body IJRA, and can be attached to and detached from the carriage HC.

In FIG. 12, 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), a flexible sheet 4005 equipped with pads 2011 corresponding to the pads 201 of the wiring board 200 of the cartridge IJC, and a rubber pad for generating elastic force to press this against each pad 2011 from the back side. A support plate 4003 for the electrical connection part that holds the inkjet cartridge I
Positioning hook 40 for fixing JC to recording position
01 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 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 is reduced 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 has a hook-side positioning surface 4006 for applying 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 corresponding to the protruding surface 4010, and forms a pad contact area between them, and uniquely defines the amount of deformation of the notch of the rubber sheet 4007 with a notch corresponding to the pad 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 above-mentioned line, the amount of deformation of each notch of the rubber sheet 4007 is made uniform, and the contact pressure of the pads 2011 and 201 is made more stable. . The distribution of pads 201 in this example is two rows above, two rows below, and two columns vertically.

The hook 4001 has an elongated hole that engages with the fixed shaft 4009, and uses the movement space of the elongated hole to rotate counterclockwise from the position shown in the figure, and then moves to the left along the platen roller 5000. By moving, 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 rotates, the cartridge IJC moves toward the platen roller and moves to a position where the positioning protrusion 2500°2600 can come into contact with the positioning surface 4010 of the front plate, and the hook 4001 moves to the left. 90° hook plane by 4
002 is in close contact with the 90'' surface of the claw 2100 of the cartridge IJC, and the cartridge IJC is moved to the positioning surface 2500.
Pads 2'01 and 2011 rotate in a horizontal plane around the contact area between pads 2'01 and 2011, and finally contact between pads 2'01 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 in complete contact with each other. The two-surface contact and the surface contact between the wiring board 300 and the positioning surface 4006 are simultaneously formed, and the holding of the cartridge IJC with respect to the carriage is completed.

In this drawing, the claw 2100 that engages with the 90@ corner engaging surface 4002 of the carriage positioning hook 4001 is positioned so that the force for positioning the carriage acts in a plane area parallel to the reference plane. It is configured.

As shown in these drawings, among the four recesses 61a protruding into the storage space, the depth of the recess on the side where the discharge port is located is increased so that the discharge port is located deep within the storage space. For example, the outlet is better protected. at the same time,
This prevents the user from inserting the inkjet cartridge in the wrong direction (so-called incorrect insertion prevention).
You can also do that.

The wall portion 61c particularly needs to have sufficient strength, and is formed of such a material and thickness. The thickness of the wall portion 61c is
Although it may be selected as appropriate depending on the type of constituent material, it is, for example, 0.1 mm or more, preferably 0.3 mm or more, more preferably 0.5 mm or more, and the upper limit is, for example, 1.2 mm or less.

On the other hand, it is preferable that the recessed portion 61a has cushioning properties that buffer or absorb impact in order to protect the contents. That is, if the recessed part 61a is formed to have the same strength and rigidity as the wall part 61c, the impact received by the wall part 61c will easily press against the contents directly, and this may not necessarily cause damage to the contents. . From this point of view, it is desirable that the recess 61a be formed with a relatively thin wall thickness and have elasticity. The thickness of the recess 61a can also be appropriately selected depending on its constituent material; for example, the thickness is 0.8 mm or less,
Preferably 0.6 mm or less, more preferably 0.4 mm
The lower limit is, for example, 0.05 mm or more.

As the constituent material of the container body 61, various resins and the like can be mentioned. The container body 61 is manufactured by integral molding using resin, 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 61 by integral molding. Among them, for example, acrylonitrile-butadiene-styrene copolymer resin (A
The injection molding method using a resin such as BS resin), polystyrene, polypropylene, polyethylene, or polyethylene terephthalate allows easy adjustment of the thickness of the wall portion 61c and the recessed portion 61a, and can be performed at relatively low cost.
This is suitable because desired characteristics can be easily imparted to each part.

Further, by providing the storage portion 61b at the bottom of the container body 61, the container body 61 and the bottom plate 63 can be integrated easily and reliably. The storage section 61b includes the container body 6
When one part is integrally molded, it can be molded simultaneously with other parts. The thickness of the storage portion 61b may be approximately the same as that of the wall portion 61c. This storage portion 61b includes ribs 61e for reinforcement along the area 62 that is integral with the container body 61 and the lid member 63.
is preferably provided. Although the rib 61e is provided so as to protrude toward the lid member 63 in FIG. 15, the protrusion may be in the opposite direction. However, the former is preferable because the container body 61 and the lid member 63 can be integrated more reliably using the protrusion.

By making the corners of the concave portion 61a and the rising portions of the walls/portions 61c curved as shown in the figure, the shock absorbing properties thereof can be improved. The radius of curvature of the curved portion is preferably relatively large, and is appropriately selected depending on the size of the recess 61a, for example, 2 mm or more, preferably 3 mm or more.
It is set to be at least 5 mm, more preferably at least 5 mm.

The shape of the recess 61a is that of the inkjet cartridge IJ.
It is selected as appropriate to effectively protect C and fix the position within the packaging container. In the illustrated example, the inkjet cartridge IJC is supported by four recesses 61a, and this form can be said to be the most suitable from the standpoint of protecting the inkjet cartridge IJC and fixing its position. The number can be selected as appropriate.

If the clearance between the supporting portion of the inkjet cartridge in the recess 61a and the inkjet cartridge is too large, the inkjet cartridge may wobble or shift within the packaging container, which is undesirable; This is not preferable because the storage performance becomes poor and the impact from the wall portion 61c is easily transmitted. These clearances may be appropriately selected depending on the structure of the recess 61a and the matching between the recess 61a and the inkjet cartridge, but are, for example, 0.5 mm to 3 mm, preferably 0.5 mm to 3 mm.
It can be about 5 mm to 2 mm.

The material and thickness of the lid member 63 are selected depending on the weight, strength, etc. of the inkjet cartridge. As the lid member 63, for example, a film, sheet, or plate made of resin or metal, or a laminate containing at least one of them is used. When using this laminate as the lid member 63, the surface layer of the lid member 63 on the non-adhesive side to the container body 61 (hereinafter,
If the outer layer (referred to as the "outer layer") is paper, the paper may release or absorb moisture and become curled under the influence of environmental changes, especially changes in humidity. Preferably, a moisture barrier layer is coated to prevent deformation.

In this case, the container body 61 and the lid member 63 due to curl deformation
It is also possible to prevent force from being applied to the adhesive portion 62 in the peeling direction. As the moisture barrier layer, polypropylene having a thickness of 15 to 1100 μm is most preferable from the viewpoint of cost and strength.

Various methods can be used to integrate the container body 61 and the lid member 63 after the inkjet cartridge IJC is housed in the container body 61. For example, the container main body 61 and the lid member 63 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 63, and can be used to perform these bondings. The method using the easy beer layer allows the lid member 63 to be easily removed from the container body 61 when unpacking.

This has the advantage that there is less risk of damaging the jet cartridge. In this way, Easy Beer is suitable when considering the humidity retention property of the contents such as moisture resistance and ease of opening. This easy beer layer includes, for example, various hot melt types, polyethylene types,
A layer made of Eval type etc. can be used.

In terms of handling, it is preferable that the lid member 63 is provided with a grip portion 63a that is used when peeling off the lid member 63 from the container body 61. Although this knob portion 63a is provided at a location close to the ejection port of the inkjet cartridge in FIG. 1 and the like, it is more preferably provided at a location as far away from the ejection port as possible. The reason is,
This is to avoid accidentally touching the ejection port part of the inkjet cartridge, which should be particularly protected, when the lid member 63 is peeled off from the container body 61 using the knob 63a.

In addition, by selecting the constituent materials 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 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, as the constituent material of the container body 61. can. Note that polypropylene is suitable from the viewpoint of manufacturing cost, moldability, processability, etc.

Similarly, as a constituent material of the lid member 63, a resin film, sheet or board material, or a material obtained by coating a paper sheet or board material with a vinylidene chloride layer or an aluminum layer,
By using a material such as polypropylene that prevents moisture permeation, a good humidity environment maintenance function can be obtained.

In order to have good shock-absorbing properties and humidity environment maintenance functions, for example, a material made of paper with an aluminum layer and a layer for sealing adhesion to the container body (for example, an easy beer layer) can be used. A lid member having a polypropylene layer on the non-adhesive surface (outer surface) is suitable for preventing curling. In particular, a laminate in which an aluminum layer is provided and a polypropylene layer is provided as the outermost layer on the non-adhesive side is preferable from the viewpoints of cost, impact cushioning properties, and humidity environment maintenance function.

In addition, when using a vacuum forming method using polypropylene to form the container body 61, as described above, the recess 61a
It is preferable to form the upright portion of the wall portion 61c as a curved portion in order to improve the shock-absorbing properties of the container body 61 and to provide the container body 61 with the above-mentioned humidity environment maintenance function.

Further, the portion of the raw material sheet other than the portion that will become the ceiling portion 61 cm 2 is stretched in a vacuum from the ceiling 61 cm 2 of the container body 61 toward the bottom surface (flange 61 b ) to form the recess 61 a 1 and the wall portion 6 .
By using male molding to mold the 61 cm side surface of 1c, curved parts, etc., it is possible to improve the uniformity of the thickness of each part, eliminate the occurrence of pinholes, and improve moisture permeation prevention properties in each part. It is preferable for increasing.

In addition, if the container body obtained by vacuum forming does not have a curved part, the boundaries between the wall and the recess of the container body, and the boundaries between the wall and the flange, etc., will be formed as thin corners, resulting in pinholes. In addition, the product may be more likely to be damaged when dropped, and the moisture permeation prevention properties of the affected area may be reduced. For this reason, by forming these boundary parts as curved parts, the formation of thin walled parts is more effectively prevented, and good moisture permeation prevention properties are obtained more uniformly over the entire container body. It is possible to obtain an outer peripheral portion that is more resistant to drop impact.

Furthermore, if a transparent or translucent material is selected for the container body 61 and/or the bottom plate 63, the inkjet cartridge 62 can be seen through in the packaged state.

By the way, as shown in FIG. 19, by providing a covering member 3 that covers (seals) the ejection port on the ejection port surface of the inkjet cartridge, the evaporation of ink from the ejection port can be extremely reduced. The humidity of the storage space can be maintained appropriately, and therefore curling of the lid member can be prevented, and the ink supply path from the ink tank to the ejection port can be maintained in a good condition.

The cover member 3 according to the present invention is not limited to the tape-shaped one described above, but it is easy to handle (for example, it is easy to peel off), and it is useful for maintaining an airtight state of the discharge port. A tape-like material is most suitable because of its superior properties, its thinness, which hardly affects the size of the inkjet cartridge, and its ability to be formed at relatively low cost. As a material for the cover member 3, for example, polyethylene terephthalate can be used.

Furthermore, in FIG. 19, a holding member 4 for holding the cover member 3 against the inkjet cartridge IJC is provided on the inkjet cartridge. A preferred embodiment of the holding member 4 is a cap member in which an ink absorber 6 is disposed at a position corresponding to the ejection port.

Providing such a holding member 4 prevents the user from inserting his or her hand into the ejection port when taking out the inkjet cartridge IJC from the storage container. This is more suitable from the point of view of protecting the parts. This pressing member 4 is preferably provided so that even if the inkjet cartridge moves within the storage container within the clearance range, it does not come into contact with the wall portion 61c of the storage container main body 61 and does not move.

FIG. 16 is a developed perspective view showing another example of the inkjet cartridge storage container (packing container) of the present invention, and FIG. 17 is a perspective view of the same after assembly.

Further, FIG. 18 shows a left side view (a), a top view (b), a front view (C), a right side view (d), and a bottom view (e) showing other examples of the storage container of the present invention, respectively. 15 is a partially enlarged view (f) showing the storage section of the storage container main body (however, the portions treated as a front view are different from FIG. 15); FIG.

This example is the same as the example shown in FIGS. 19, 14, and 15 described above except for the shape of the recess 61a of the container body 61. Recess 61 of container body 61 in this example
The portion a is formed halfway without reaching the storage portion 61b, and is sloped at a predetermined angle to support the inkjet cartridge. Although the former example is better in terms of fixing the position of the inkjet cartridge in the storage space, the present example can also achieve an effect sufficient to substantially achieve the object of the present invention.

Although it is preferable to provide the cover member 3, it is not necessarily necessary to provide it, and the present invention also includes a configuration in which it is not provided.

Although the invention in which the cover member 3 is provided is superior in terms of preventing the evaporation of moisture in the ink filled in the inkjet cartridge, the invention in which the cover member 3 is provided is superior to the invention in which the purpose of the present invention can be substantially sufficiently achieved without providing the cover member 3. effect can be obtained.

On the other hand, the holding member 10 that holds the storage container 101 described above
4 is an opening 102a that is larger than the outer edge of the container body 61 of the storage container 101 and is opened so that the container body 61 can be inserted;
Opening area 1 having an opening end 6 part 102b larger than the outer edge of the storage part 61b and a peripheral part 102c of the end part 102b
If.
L f gon tS Luo hill '1 anti 1. Car Dealer Name Hyakuhaku 11'1
flP-* and a holding member 104 made of cardboard.

The opening 102a is formed into an opening having a shape and size substantially equal to the shape and size of the container body 61 so that the container body 61 can be inserted therein and the container body 1 will not wobble after insertion. Therefore, due to the presence of the storage section 61b provided around the entire circumference of the container main body 61 on the storage opening side, the opening 1
The container body 61 will not come out from the container 02a.

Further, in this embodiment, the opening area 1 of the holding member 104
02, the folded plane area 103, and the display area section 105,
- formed by sheets of paper material; The storage portion 61b of the storage container 101 is held by the lid member 6 of the storage container 101 inserted into the opening 102a of the opening area 102.
This is done by folding it in two so that the folded flat area 103 is on the third side. By doing this,
The storage container 101 is clamped and fixed to prevent the storage container 101 from falling off.

As shown in FIG. 20(C), the opening area 102 and the folded plane area 103 are both connected to the opening peripheral area 102c.
The bonding is achieved by an adhesive region 103b formed between the folded plane region 103 and the folded plane region 103 corresponding thereto. In particular, in this embodiment, the opening area 102 and the folded flat area 10
3 is folded back and joined, so the folded area does not serve as the adhesive area 103b.

In addition, the folded plane region 103 has a diameter that is slightly reduced toward the end, as shown in FIG. 20(C).

As a result, the bonding area of the bonding region 103b decreases toward the end. In this example, the bonding area is reduced as the area of the folded plane region 103 is reduced, but the bonding area may be actively reduced regardless of the shape of the folded plane region 103. . Note that, although the grip portion of the lid member 63 for sealing the container body 61 is provided to protrude from the occupied area of the storage portion 161b, the adhesive area 103b described above is designed to prevent the grip portion from being glued. It is defined as an area.

By the way, in the opening area 102, as shown in FIG. 20(a), an opening slit 111 is formed which is used to take out the packaged storage container 101. In this example, the notch 111 is formed as a so-called zipper that can be opened by peeling off the band member from one end to the other end.

If the unsealing notch 111 has a zipper-like configuration, the adhesive area 111 described above needs to have a configuration excluding a portion of the zipper.

In FIG. 1(a), the zipper formed as the opening slit 111 is near the end of the area that is integral with the opening area 102 and the folded plane area 103, and the storage container 101 faces the zipper. It is formed approximately near the center on the surface side of the holding member 104.

However, the position where the zipper is formed is not limited to this, for example, as shown in FIG.
and an opening 102a which is located approximately in the vicinity of the center of the area integral with the folded plane area 103 and faces the storage container 101.
It may be formed in two parts at a position sandwiching the two parts.

That is, in this example, it is preferable that the opening slit 111 be formed on the surface side facing the storage container ioi. If the notch 111 for opening is formed on the surface side where the opening 102a is formed in this way,
Even if an external impact is applied to the storage container 101, the stress on the opening notch 111 is extremely small, and damage to the notch 111 is prevented.

The opening 111 is the opening 1 as described above.
As long as it is formed on the surface side where 02a is formed, it can be formed in a predetermined area without departing from the spirit of the present invention.

The inkjet cartridge package configured in this way includes a storage container 101 that houses an inkjet cartridge and is sealed by the lid member 63.
It is inserted into the opening 102a provided in the opening area 102. In this state, the portion that will become the folded flat area 103 is folded back, and the storage container 101 is clamped and fixed from the lid member 63 side.

That is, the storage portion 61b of the storage container 101 is located in the opening area 1.
It is clamped and fixed between the opening end 102b of 02 and the corresponding folded flat area 103.

Thereafter, the package as shown in FIG. 1(a) is assembled by bonding the bonding area 103b shown in FIG. 20(C) by heat fusion.

Further, the present invention may be configured as shown in FIG. 21(a) and FIG. 21(b). That is, Fig. 1 (a
), an opening 102a is formed on the side of the holding member 104 that was the folded flat area 103 in FIG. 1(b),
This is folded back and the storage container 101 is fixedly held on the front side. In other words, Figure 1(a)
In Figure (b), an opening 102a is formed on the side of a vertically long substantially rectangular member, and this is folded back to the back side by a substantially square planar member to sandwich the storage container 101. On the other hand, in FIGS. 21(a) and 21(b), an opening 102a is formed on the substantially square member side, and this is folded back to the front side, and a vertically long substantially rectangular planar member is formed on the back side. It has a configuration in which the storage container 101 is held between the sides.

Also in FIGS. 21(a) and 21(b), the unsealing notch 111 is provided on the opening area 102 side, which is the front side and is formed by folding back. By doing so, the opening slit 111 can be made so that it will not be easily torn by external impact.

By the way, when the storage container 101 containing the inkjet cartridge is displayed with the package hooked by the hook receiving part 104a of the holding member IO4, the head part IJH constituting the inkjet cartridge moves in the direction of gravity (the six directions of the arrows). ) The attachment is held by the holding member 104 so as to be located below.

The reason why the head IJH is installed so that it is positioned downward in the direction of gravity is that when the head IJH is positioned upward in the direction of gravity, ink moves downward and air enters from the ejection port. This is to prevent the ink path, liquid chamber, etc. from being filled with air bubbles.

Therefore, even when the inkjet cartridge is held horizontally or vertically, the head portion IJH is held downward in the direction of gravity.

In this example, the holding member 104, especially the storage container 101
Since the storage area has a double structure, even if an external impact such as a fall is applied, the impact is sufficiently interfered with by the holding member 104. Therefore, the storage container 101 can be properly stored and held without causing any deformation or the like and without having any adverse effects on the inkjet cartridges that are stored.

Further, the holding member 104 is shown in FIG. 1(a) and FIG. 1(b).
, FIG. 21(a), FIG. 21(b), etc., when the plane area 103 is folded back, the opening forming area 102 is placed in the area adjacent to the opening forming area 102.
When it is folded back to the front side, a continuous plane is provided in an area adjacent to the folding plane area 103, and a display section 105 is provided on which information such as how to take out and handle the label or inkjet cartridge can be written effectively. There is. In addition, since the area integral with the opening forming area 102 and the folded plane area 103 is only the area where the opening 102a of the opening forming part 102 is formed, the area opposite to the surface facing the storage container 101 is , that is, the opening notch 103
The surface side provided with a can also effectively function as the display section 10 area.

In the embodiment described above, an example was described in which the inkjet cartridge IJC was stored in the storage container, but the storage container also contained various office equipment supplies such as toner, ink ribbon, floppy disk, magnetic tape, and various records. Needless to say, it is also possible to store the medium.

The present invention brings about excellent effects particularly in a recording head used in a bubble jet type recording apparatus among inkjet recording types.

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, it is necessary to arrange the liquid (ink) in accordance with the sheet and liquid path that hold it. The electrothermal converter that is
By applying at least one drive signal corresponding to recorded information and providing a rapid temperature rise above 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 a hole that absorbs pressure waves of thermal energy is disclosed. The present invention is also effective as a configuration based on Japanese Patent Application Laid-Open No. 138461 of 1981, which discloses a configuration in which a discharge portion corresponds to a discharge portion.

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] According to the invention of claim 1, the storage part of the storage container housing the inkjet cartridge, which is kept in a sealed state so that it can be maintained in a predetermined internal environment, is sandwiched between two opposing surfaces. With this, the function for satisfying the characteristics required for a storage container and the function for holding the storage container and mitigating external impact could be separated with a simple configuration.

As a result, it is possible to provide an inkjet head cartridge package that can reliably and inexpensively protect the inkjet head cartridge, which is a stored object that is easily damaged, from shocks caused by vibrations and drops during transportation.

In addition, since the opening notch is formed on the front side of the package, it is possible to make the notch extremely strong against external shocks, and it is possible to easily open the package without damaging the storage container or holding member. It can be performed.

As a result, it is possible to provide an inkjet head cartridge package in which, for example, instructions for handling the inkjet head cartridge inside the storage container can be read easily without damaging symbols, characters, etc. drawn on the surface of the holding member.

In addition, due to the above-mentioned functional separation effect, the storage container is securely held between the two opposing surfaces, so it can be used under various environmental conditions, such as under reduced pressure (atmospheric pressure, where the recording head is hermetically sealed). In this case, there is a technical problem that the sealing part peels off due to the relative pressure increase inside the container in a reduced pressure environment.

Furthermore, according to the invention of claim 4, when the package is displayed, the head portion of the inkjet head cartridge in the storage container is stored so as to be positioned downward in the direction of gravity, so that air does not enter the head portion. is prevented.

As a result, it is possible to provide an inkjet head cartridge package that can store the inkjet head cartridge in a state that allows good printing even if it is attached to a recording device and starts recording immediately after being taken out from the storage container. .
