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.

[Problem to be Solved by the Invention J] However, for example, in packaging containers using cardboard boxes, the local strength of the cardboard itself is not necessarily sufficient, and local external forces are likely to cause dents and damage, especially when the contents are 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 uneven parts.

Furthermore, there are packaging containers that use foamed resin molded products, such as urethane foam and styrene foam, which have a shock-absorbing effect, as shock-absorbing materials in packaging. This type of packaging container is easy to mold to fit the shape of the item to be stored, and has good shock-absorbing properties, so it is extremely effective in fixing the position of the item in the packaging container and protecting it. To Nihama I/.

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.) Such a significant increase in occupied space is due to the reduction in 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 by local impact, so it is common to insert a sleeve-shaped cardboard sheet over the Styrofoam case, or to cover it with cardboard. can be,
Packaging costs are also high.

In addition, a molded container body made of vinyl chloride such as a blister bag is combined with 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. This has the disadvantage that airtightness is likely to be impaired if the product collides with other products 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).

The storage container for this Inkzimot head cartridge 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 recessed 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, the container body and the plate-like member are directly and tightly joined, and it is difficult to avoid heat loss by placing them together with other articles, for example.
When the container body and the plate-like member were peeled off, there were cases where the container body and the plate-like member were peeled off. 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 the two are peeled off, a part of the material forming the joint 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 object of the present invention is to provide an inkjet cartridge package that can be used in various ways.

[Means for Solving the Problems] The present invention has been proposed to achieve the above-mentioned object, and includes a storage portion for storing an inkjet cartridge, a flange portion integrally formed with the storage portion, and a storage portion for storing an inkjet cartridge. a storage container comprising as a component a lid member that forms a sealed space with the storage section by joining with the flange portion;
an opening forming member having an opening larger than the outer edge of the storage portion of the storage container, an opening end that abuts the outer edge of the flange portion, and a peripheral portion of the opening end; and a holding member comprising a flat member, and the flange portion of the storage container is held between two opposing surfaces of the opening forming member and the flat member.

In addition, in order to take out the storage container from the holding member,
A storage unit that includes a storage unit that stores an inkjet cartridge, a flange unit formed integrally with the storage unit, and a lid member that forms a sealed space with the storage unit by joining the flange unit. a container; an opening forming member having an opening larger than the outer edge of the storage portion of the storage container; an opening end that abuts the outer edge of the flange; and a peripheral portion of the opening end; and the opening forming member. The present invention is characterized by comprising a holding member having a flat member facing the flat member and a notch for opening provided in the flat member.

Furthermore, from the viewpoint of maintaining the ink filling state in the head section of the inkjet head cartridge housed in the storage container, the present invention further includes a storage section for storing the inkjet cartridge, a flange section integrally formed with the storage section, and a flange section. a storage container comprising as a component a lid member that forms a sealed space with the storage portion by joining with the storage container; an opening larger than the outer edge of the storage portion of the storage container; and an opening that abuts the outer edge of the flange portion. an opening forming member having an end portion and a peripheral portion of the opening end portion; a flat member facing the opening forming member; and a flat member formed adjacent to the opening forming member so as to be hookable when displayed. An inkjet cartridge package comprising: a display member having a hook portion; and a holding member having a hook portion, wherein the head portion of the inkjet cartridge is disposed downward with respect to the direction of gravity when the inkjet cartridge package is in a hooked state. It is characterized in that it is stored in the storage container so as to be stored in the storage container.

[Function] By creating a package with a separate structure, the storage function for sealing storage of the inkjet cartridge as the stored item and the holding function for holding the storage container that achieves the storage function are resistant to external shocks. It becomes possible to achieve a highly effective protection function.

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

Furthermore, a notch for taking out the storage container from the holding member is formed in the holding area of the storage container, and a display area is provided in a different area from this, making it easy to see how to take out or handle the stored items. 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 which is a storage section in which an inkjet cartridge can be stored, and a flange portion 61b which is a region where a lid member 63 for making this container main body 61 a sealed space is joined. 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 that abuts the outer edge of the flange portion 61b; an aperture forming member 102 having a peripheral portion 102c; a plane member 103 disposed opposite to the aperture forming member 102 and cooperating with the aperture forming member 102 to sandwich the flange portion 61b;
The holding member 104 includes a holding member 104.

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.

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 partial cross-sectional view illustrating the configuration of attaching and detaching the recording head of this embodiment to the main body of the recording apparatus.

In Figure 13, IJC is an inkjet cartridge,
The recording head (fifth
It includes a thermal energy generator 91 shown in the figure, a substrate 100 on which an electrode 92 is formed, and an orifice plate 400 having a plurality of discharge ports 41. In this embodiment, the liquid path 14
A top plate 1300 and a plate 400 for forming 0 are integrally molded. ) shows a recording head that can be attached to and detached 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 41 represents 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 portion surface l. Reference numeral 2 denotes grooves provided on the upper and lower surfaces recessed from the discharge part surface 1, and in this example, four grooves are formed as shown in the figure. 53 is base plate 1
This side groove is located on the side facing the groove 2 and has four grooves that are continuous with the grooves of the groove 2. When a large amount of ink accumulates in the groove 2 due to ink scattering, it guides it downward. It is possible to achieve the effect of This recording head groove portion 2 is
This is to maintain the engaged state by receiving an elastic pressing force from the groove portion 51 of the cap 4.

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 l, 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. Each of the arm parts 5.5 has three grooves 51 on its inner surface 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 above the base plate 1o, and at the same time, the elastic body 6 is provided until it faces the base plate 10. 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 such that it slightly contacts the back surface 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 one elastic body is concentrated on the discharge port, and for this purpose, the part facing the base plate 10 in the configuration of the elastic body 6 in FIG. 2 is removed. There is. Further, in this embodiment, the portion 7.7 functions 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 2.51 can be achieved by positioning the recording head between the arms 5.5 of the cap and releasing 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, adjustment can be easily made by mutually balancing the elastic pressing force of the arm and the elastic force due to deformation of the elastic body 6. . In this state, if the same number of upper and lower grooves are engaged, the overall balance will be optimized.
Since the sealed state becomes strong and the pressure distribution is also optimized, the sealed state is ensured. As for the elastic material and thickness of the elastic body 6, any material can be used as long as it can press the sheet 3 and maintain the sealing force when the groove 2.51 is 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
It is a flexible sheet of about 301Lm, and the elastic body is:
The sponge is approximately 3mm thick and is either 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 3011 m is formed on the upper and lower surfaces with respect to a step forming surface G of about 70 μm. The present invention can form a reliably sealed state even on such a step-shaped surface.

As can be seen in FIG. 6, the liquid chamber has a region Z that is continuous with the liquid path and widens toward the ink receiver section, and a slope 21 that extends from the ink receiver section toward the region. The extension line of the line reaches a surface position P0 of the substrate 8, which is the side surface on which the ejection energy generating means H of the liquid path facing the area is arranged. In this embodiment, this slope 21 is the center line C of the ink liquid path.
2 and the extension line of the liquid path is 22 degrees, and the left and right inner wall surfaces have an angle B of 15 degrees.

Due to the existence of this expanding region 2, 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 generating 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, so that the occurrence of recording defects can be significantly delayed. Moreover, since the extension line of the slope reaches the side surface where the discharge energy generating means is arranged in the liquid path facing the area, an impact is generated and existing air bubbles try to enter the liquid path along the slope. Since the side surface where the ejection energy generating means is arranged also exists as a barrier, large air bubbles will not enter the liquid path 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 orifice plate side end opening of the liquid path, 111 indicates an isosceles trapezoidal shape of the inner space 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,
It is possible to prevent the occurrence of ink turbulence during recovery and stabilize the bubble discharge effect. 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 P1 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 C,) 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 P3 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 acid 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 OR3 with different angles (deviation point H%I), and the ejection direction of droplets is constant in the extending direction of the line C1, so the recording surface is It is a plane perpendicular to the line C1. 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 2 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 2 is 10 degrees, which is the angle of the slope 21. 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,
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 1o
The structure is such that the portion is reliably pressed 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 using the groove portion 51.
There is also the advantage that it can be done by sliding along the .

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) and a flexible sheet 4005 equipped with pads 2011 corresponding to the pads 201 of the wiring board 200 of the cartridge IJC, and a flexible sheet 4005 for generating elastic force to press this against each pad 2011 from the back side. An electrical connection support plate 4003 holding 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 L5 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 reinforcing ribs 4004 not in the direction of the ribs but in the vertical direction? ! 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 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 L+, the amount of deformation of each notch of the rubber seal 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 4001 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 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. By 90' hook face 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.
The pads 4010 and 2010 rotate in a horizontal plane around the contact area, and finally the pads 201 and 2011 come into contact with each other.

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 engaged by the 90° engagement surface 4002 of the carriage positioning hook 4001 is positioned so that the positioning force for the carriage acts in a plane area parallel to the reference plane. It is configured.

Although the above embodiments do not disclose all the combinations of the structures disclosed in the claims of the present invention, the present invention includes appropriate combinations of the above structures.

The present invention, which is technically related to the above-mentioned FIGS. 2 to 13, will be described in detail below using FIGS. 1 and 14 onwards.

This packaging container is formed of a container body 61 and a lid member 63, which are joined together and used as a packaging container.

The container body 61 includes a wall portion 61c that is maintained in a non-contact state with the inkjet cartridge IJC that is the content, and a wall portion 61c that protrudes from the wall portion 61c toward the content storage area and supports the inkjet cartridge IJC that is accommodated therein. A recess 61a for fixing the position and a flange 61b for integrally joining with the lid member 63 are provided. The ejection opening of the inkjet cartridge IJC is maintained in a non-contact state with the wall in the storage space. 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 also prevents the user from inserting the inkjet cartridge in the wrong direction (so-called erroneous insertion prevention).

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 portion 61a is formed to have the same strength and rigidity as the wall portion 61c, the impact received by the wall portion 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 recessed portion 61a can also be appropriately selected depending on its constituent material, but is set to, for example, 0.8 mm or less, preferably 0.6 mm or less, more preferably 0.4 mm or less, and the lower limit is, for example, 0.05 mm. This is considered to be the above.

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
BS resin) Injection molding using a resin such as polystyrene, polypropylene, polyethylene, polyethylene terephthalate, etc. allows the thickness of the wall portion 61c and the recessed portion 61a to be easily adjusted, and can be performed at relatively low cost. This is preferable because characteristics can be easily imparted.

Furthermore, by providing the flange portion 61b at the bottom of the container body 61, the container body 61 and the bottom plate 63 can be easily and reliably joined. The flange portion 61b can be molded simultaneously with other parts when the container body 61 is integrally molded. The thickness of the flange portion 61b may be approximately the same as that of the wall portion 61c. This flange portion 61b is preferably provided with a reinforcing rib 61e along the joint region 62 between the container body 61 and the lid member 63. 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 more securely joined using the protrusion.

By making the corners of the concave portion 61a and the rising portions of the wall 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.
mm or more, preferably 5 mm or more.

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 M (hereinafter referred to as
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.

Propylene is most preferred.

Various joining methods can be used to join 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.

It is preferable in terms of handling that a knob 63a is provided to be used when performing the ↓intersection zL temple 6s. 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 that the knob 63a
This is to prevent the user from 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 by hand.

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. In addition, manufactured by: Notice 17. l- plasticity t1 propylene is preferred.

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.

Furthermore, 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 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. It is preferable that this holding member 4 is provided so that even if the inkjet cartridge moves in the LIV storage container within the AII5 clearance, it does not come into contact with the wall 61c of the LIV storage container main body 61 and move. .

FIG. i6 is an exploded 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. and a partially enlarged view (f) showing the flange part of the storage container main body (however, the parts treated as a "front view" are different from FIG. 15).
.

This example is the same as the examples shown in FIGS. 1, 14, and 15 described above except for the shape of the recess 61a of the container body 61. Recess 61a of container body 61 in this example
is formed halfway without reaching the flange 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 necessary to provide the cover member 3.
) is included as an invention.

Although the invention of claim (1) is superior in terms of preventing evaporation of water in the ink filled in the inkjet cartridge, the invention of claim (9) substantially sufficiently achieves the object of the present invention. It is possible to obtain the desired effect.

On the other hand, the holding member 104 has an opening 102a that is larger than the outer edge of the container body 61 and into which the container body 61 can be inserted.
, an opening end portion 102 that abuts the outer edge of the flange portion 61b.
b and a peripheral portion 102c of the end portion 102b; a planar member 103 disposed opposite to the opening forming member 102 and cooperating with the opening forming member 102 to sandwich the flange portion 61b; A display area portion 105 adjacent to the member 102 is provided.

The opening 102a is formed into an opening that is approximately equal in shape and size to the container body 61 so that the container body 61 can be inserted therein and the container body 1 does not wobble after insertion. Therefore, due to the presence of the flange portion 61b provided around the entire circumference of the container body 61 on the storage opening side, the container body 61 does not come out from the opening LO2a.

Further, in this embodiment, the opening forming member 102, the plane member 103, and the display area portion 105 of the holding member 104 are -
It is formed by a sheet of paper. The flange portion 61b of the storage container 101 is held by the opening forming member 1.
This is done by bending the flat member 103 in half so that the flat member 103 is on the side of the lid member 63 of the storage container 101 inserted into the opening 102a of the storage container 101. By doing this,
The storage container 101 is clamped and fixed to prevent the storage container 101 from falling off.

The opening forming member 102 and the plane member 103 are shown in FIG.
As shown in C), the two are joined by an adhesive region 103b formed between the opening peripheral portion 102c and the corresponding planar member 103. In particular, in this embodiment, since the opening forming member 102 and the planar member 103 are folded back and joined together, the folded region does not serve as the bonding region 103b.

In addition, the planar member 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 planar member 103 is reduced, but the bonding area may be actively reduced regardless of the shape of the planar member 103. Note that the grip portion of the lid member 63 for sealing the container body 61 is provided to protrude from the occupied area of the flange portion 161b, but the above-mentioned adhesive area 10
3b is defined as an area where the knob portion is not bonded.

Incidentally, as shown in FIG. 20(C), the planar member 103 is formed with an opening slit 103a that is used to take out the packaged storage container 101. In this example, the notch 103a 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 103a has a zipper-like configuration, the adhesive area 103b described above needs to have a configuration excluding a portion of the zipper.

In FIG. 20(C), a notch 103 for opening is shown.
The zipper a is formed approximately at the center of the flat member 103. However, the position where the zipper is formed is not limited to this, for example, the adhesive region 10 is formed near the folded portion of the plane member 103 or in the farthest region from the folded portion of the plane member 103.
It may be formed near 3b.

By forming this zipper-shaped opening slit 103a at approximately the center of the planar member 103 as described above, the storage container 101 receives an impact and a force that presses the planar member 103 is applied. Even in such a case, the pressing force is interfered with by the adhesive region, and the possibility that the zipper-shaped opening cut portion 103a will be torn is extremely reduced. Even if the zipper part is torn, the pressing force applied to the two-part planar member 103 is distributed to both sides, so the planar member 103 will not separate from the holding member.

In particular, in this example, the bonding area of the bonding region 103b is decreased from the folded portion of the planar member 103 toward the end. Therefore, the peeling force from a portion of the zipper toward the end of the flat member 103 is initially large and gradually becomes smaller. Therefore, even if a portion of the zipper is torn due to an external force impact on the storage container 101, the flat member on the end side will not easily peel off from the opening forming member 102. On the other hand, the flat member on the side from the part of the zipper toward the folded part has an adhesive force that gradually increases toward the folded part, so that it does not easily peel off due to an external impact.

Note that the opening slit 103a is not limited to the above-mentioned configuration, and for example, as shown in FIG. It may also be configured to include a finger catch portion 103a-1 that allows insertion.

The inkjet cartridge package thus constructed is assembled as shown in FIG. 22. That is, a storage container lot containing an inkjet cartridge and sealed by the lid member 63,
It is inserted into the opening 102a provided in the opening forming member 102. In this state, the portion that will become the planar member 103 is folded back, and the storage container 101 is clamped and fixed from the lid member 63 side. That is, the flange portion 61b of the storage container 101 is clamped and fixed between the opening end portion 102b of the opening forming member 102 and the corresponding region of the planar member 103. Thereafter, the package as shown in FIG. 1 is assembled by bonding the adhesive region 103b shown in FIG. 20(c) by heat fusion.

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 104, the head part IJH constituting the inkjet cartridge moves in the direction of gravity (six directions of 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 as shown in FIG. 1, or vertically as shown in FIG. 23, the head portion IJH is located below in the direction of gravity. It is maintained as follows.

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 to be stored.

Further, as shown in drawings such as FIG. 1 and FIG. 20(a), the holding member 104 has a continuous plane in an area adjacent to the opening forming area 102, and has a continuous flat surface for removing labels and inkjet cartridges. It has a display section 105 on which information such as how to use and how to handle can be written effectively. In addition, the planar member 103 has the opening 1 of the opening forming portion 102.
Since it is formed so as to cover only the area where 02a is formed, the side opposite to the side facing the storage container 101, that is, the side provided with the opening notch 103a, also effectively functions as the display section 10 area. can be done.

Next, FIGS. 24 and 25(a) to 25(
An embodiment example showing another form will be described using c).

FIG. 24 is a perspective view schematically showing another configuration example of a package to which the present invention is applied, and FIGS. 25a to 25C are a side view, a top view, and a bottom view of the package shown in FIG. 24. FIG.

As shown in these drawings, the inkjet cartridge package includes a container body 61, which is a storage section in which an inkjet cartridge can be stored, and this container body 6.
A storage container 1 provided with a flange portion 61b as a region for joining with a lid member 63 for making the storage container 1 into a sealed space.
01, and an opening 102a that is larger than the outer edge of the container body 61 of the storage container ioi and into which the container body 61 can be inserted.
Opening end 102b that contacts the outer edge of flange portion 61b
and an aperture forming member 102 having a peripheral portion 102C of the end portion 102b, and a plane member 103 disposed opposite to the aperture forming member 102 and cooperating with and sandwiching the flange portion 61b with the aperture forming member 102. The holding member 104 is configured by a holding member 104.

1, FIG. 20(a) to FIG. 20(d), FIG. 21, FIG. 22, and FIG. It has a similar structure to the inkjet cartridge package shown in . The configuration of the storage container in this example is as shown in the explanation of FIGS. 14, 15, and 19 described above.

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 ribbons, floppy disks, magnetic tapes, and various recording materials. 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.

[Effect of the Invention 1] According to the invention of claim 1, the flange portion of the storage container housing the inkjet cartridge, which is kept in a sealed state so as to be maintainable 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.

Furthermore, 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.

Further, according to the invention of claim 4, since the notch is formed in one of the two opposing surfaces that sandwich the storage container, the opening and sealing operations can be performed smoothly without damaging the storage container and the holding member. I can do it.

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

Furthermore, according to the invention of claim 7, 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. .
