DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink container packaging used for an ink jet recording apparatus.

[0002]

2. Description of the Related Art A conventional ink tank has a packing form in which a seal member of an air communication port and an ink supply port of the ink tank is adhered to a pillow bag which is a packing form.
No. 12 is proposed. In this packing form, the force that is peeled off from the seal member that has been peeled off at the time of opening allows the ink to be sprayed to be contained inside the bag, and without causing the user to consider the opening order of the air communication port and the ink supply port,
It is a packing form that is opened in order from the air communication port.

[0003]

In the conventional embodiment, when the ink capacity of the ink tank is relatively small, the environment (atmospheric pressure, temperature) surrounding the ink tank at the time of manufacturing and at the time of opening the ink tank.
, The pressure inside the ink tank may increase. At this time, if the ink tank is opened, the ink may be pushed out of the ink tank. This ink amount changes depending on the ink capacity of the entire ink tank. It increases as the capacity of the ink tank increases. Since it is desired to increase the capacity of the ink tank, when the capacity is increased, the amount of ejected ink in the conventional packing form may be so large that the ink cannot be held inside the pillow bag.

[0004] In addition, when the amount increases, the ink may enter the gap between the ink tank and the pillow bag by capillary action, and when the ink tank is held, the probability that the ink reaches the user's hand may increase.

Further, in the case of a pillow bag, a user who disregards the opening method and tears the bag to open it, and then peels off the seal member sealing the air communication port and the ink supply port of the ink tank may be considered.

[0006] In this case, when the seal member is peeled off, there is a case where the ink is splashed by the impact of the peeling of the ink from the seal member.

[0007] The above problems remain.

[0008]

1. In the present invention, a box is used as a member for packing the ink tank, and a box in which the half-life ink tank is accommodated, an ink absorbing member is arranged at a position opposite to the ink supply port and the air communication port, and the ink tank and the ink tank are contained. By laying the ink absorbing member between the boxes, even if the ink flows out of the ink tank at the time of opening, the ink is absorbed by the three absorbers. This prevents the ink from flowing out of the packing material and prevents the user from getting his hands dirty when used.

2. In the present invention, the member for packing the ink tank is in the form of a box. The box is doubled,
Unless the seal between the ink supply port and the air communication port is opened, the ink tank cannot be taken out. As a specific configuration, it is assumed that the ink tank is fixed to an inner box. The box has a structure in which the inner box is pulled out by sliding not in the vertical direction but in the horizontal direction. In order to limit the drawing direction, a lid is attached to the outer box in one of the drawing directions, and the air communication port and the ink supply port of the ink tank are sealed with a seal member. The seal member is welded to the ink tank, and adheres an end that is not folded back to the surface of the outer box so that the pull-out direction of the box is the pulling direction. Further, the other end of the sealing member is provided with a hole in a surface of the outer box to which the sealing member is adhered, and is drawn out through the hole. By adopting this packing form, it is very necessary to pull out the inner box from the outer box unless the ink tank seal is pulled open first, and in practice the ink tank can be removed without peeling the ink tank seal. It will not be removed from the box. The opening order is such that the air communication port is opened first, or an instruction is given to the user.
Furthermore, if the outer box is made of a material that is hardly broken, rather than a general paper box, the effect is further enhanced.

3. In the second embodiment, when the seal member is peeled off, the ink supply port of the ink tank is provided with an obstacle in the direction in which the seal member is peeled off when the seal is peeled off, and the ink supply port is in contact with the inside of the ink tank of the seal member. After the seal is peeled off, the packing form is pressed against a part of the packing box, and the ink is pulled out of the ink supply port of the ink tank to the outside of the packing box by being pulled by the seal member when the ink tank is opened. Jumping out can be prevented. In addition, since the part of the seal member to which the ink is attached is wiped off a part of the packing box (the part in pressure contact), the outside can be prevented from being stained with the ink.

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings.

(First Embodiment) FIGS. 1, 2 and 3
Represents the characteristics as an opening method that defines the opening order of the ink tank packaging box to which the present invention is applied. First, as shown in FIG. 1, the seal members 15 and 16 for sealing the ink supply port and the air communication port of the ink tank are pulled upward to release the inside of the ink tank to the atmosphere, and then, as shown in FIG. The inner box 12 is pulled out of the box 13, and finally, the ink tank can be taken out of the packing box as shown in FIG.

FIGS. 4 and 5 show a mechanism for opening the package.

The ink tank 11 is housed in a double packing box. That is, the inner box 12 is first pulled out in the direction of the arrow 29 in the drawing, and then the ink tank 11 is taken out of the inner box 12 as shown in FIG. Ink tank 1
One ink supply port 24 is closed by the ink supply port seal member 15. The ink supply port sealing member 15 is
Is folded back on the bottom surface of the inner box 12.
The ink supply port seal member 15, by pulling the folded end portion 15A upward, the welded portion between the ink supply port 24 of the ink supply port seal member 15 and the ink tank 11, welded to the ink supply port 24 Seal part
A force for peeling the material 15 is applied. The end 15B of the seal member 15 is
Take out the inner box 13 on the opposite side to the pull-out direction, and
It is stuck to the outer surface by adhesive. The end 15A of the ink supply port seal member 15 is similarly taken out of the hole of the outer box 13 to the outside. Further, the ink tank 11 can be easily taken out of the inner box 12, but is fixed at a low density with little backlash when stored.

If the inner box 12 is to be pulled out in the pull-out direction 29 without peeling off the ink supply port sealing member 15, as shown in FIG.
An ink supply port sealing member is provided at the end 15B of the sealing member 15.
15 pulling force (shear direction or shear direction force) works
Good. However, since the direction of this force is different from the direction of the welding stress acting between the ink supply port 24 of the ink tank 11 and the ink supply port seal member 15, the ink supply port seal member 15 can easily supply the ink tank. It does not come off the mouth 24. In addition, the ink supply port sealing member 15
A similar force acts on the adhesive portion of the outer box 13 and the ink supply port portion seal member 15. When the seal member 15 is peeled, the support portion 15 </ b> A is pulled upward in a direction perpendicular to the direction 29, and then the ink supply port seal member 15 is peeled. Otherwise, the inner box 12 cannot be pulled out of the outer box 13.

In such a case, the box may be destroyed depending on the user, so that the outer box 13 is laminated to prevent the box from being easily broken.

In the ink tank, when the air communication port and the ink supply port are sealed, when opening them, the ink supply port is released after the air communication port is released to the atmosphere. Is desirable.

FIG. 5 shows a configuration capable of coping with such a problem. That is, as shown in the drawing, the seal member 17 is integrated with the air communication port and the ink supply port, and a part thereof is taken out of the packing material 19. With this configuration, the air communication port and the ink supply port are opened in this order by the operation of pulling out the seal member 17. Further, the clamp 26 shown in FIG.
A similar effect can be obtained by sticking to the outer box.

(Second Embodiment) FIGS. 6A and 6B
Is an ink tank 11 according to the second embodiment of the present invention.
5 is an enlarged cross-sectional view of a portion of the seal member 15, which characteristically shows an action of preventing ink droplets when the seal member 15 is peeled off.

As in the first embodiment, the double box 1
The ink tanks 11 are stored in 2 and 13, respectively. In this example, the width of the seal member through hole 39 of the inner box 12 of the packing box,
The form of the sealing member 15 is characteristic.

That is, the width of the seal member through hole 39, which is a portion where the seal member 15 communicates with the outside of the inner and outer boxes 12, is reduced, and the seal member 15 passing through the hole 39 is cut into the seal member through hole 39. The surfaces are in pressure contact. In particular, the cut surface of the seal member through hole 39 is pressed against the surface of the seal member 15 that is in contact with the inside of the ink tank 11, and the following two effects can be obtained.

(A). As shown in FIG. 6B, when the seal member 15 of the ink supply port 24 is pulled out well, the ink accumulated in the gap between the seal member 15 and the ink tank 11 is drawn, and the ink droplet 45 is formed. Fifteen
Drawn in the direction of movement. In the embodiment, as shown in FIG. 6B, there is no room for the ink droplets 45 to jump out of the inner box 12, and the ink drops 45 stay inside the inner box 12. The retained ink droplet 45 is applied to the ink absorber 3
No. 5, the ink supply unit ink absorber 34, the inside of the inner packaging box 12, and the inside of the outer packaging box 13, and did not leak to the outside.

(B). Seal member 1 for ink supply port 24
5, the surface of the ink tank 11
When the seal member 15 is pulled out, the cut surface of the seal member through hole 39 that is in contact with the sealing member 15 is in contact with the cut surface of the seal member 15. There is an effect that the ink adhering to the surface can be wiped off.

(Third Embodiment) FIG. 7 shows a third embodiment of the present invention.
FIG. 3 is an enlarged cross-sectional view of a portion of a seal member 15 of the ink tank 11 according to the embodiment.
Are characterized by the positional relationship between the ink supply port 24, the seal member through hole 40 of the outer box 13 of the packing box, and the form of the seal member 15.

That is, the portion of the ink supply port 24 is covered by the outer box 13, and the seal member 15 serves as a hole for communicating with the outside of the outer box 13 through the seal member through hole 40 of the packing box outer box 13. Is provided in a portion not facing the ink supply port 24. As a result, the same effect as in the second embodiment can be obtained.

It has been confirmed that the effect of preventing ink leakage is further increased by combining the first and second embodiments. In the first and second embodiments, the seal portion of the seal member 16 (see FIG. 1) on the side of the atmosphere communication port can be configured similarly to the seal portion of the seal member 15.

(Fourth Embodiment) Ink may leak from the inside of the ink tank due to a change in the outside air environment or a shock at the time of physical distribution or the like. In particular, ink is stored on one side through a negative pressure generating member. On the other hand, in the case of an ink tank of a type having each chamber for directly storing ink, if the ink accumulates in the buffer portion of the ink tank, or if air enters the ink storage portion of the ink tank, the outside air temperature during distribution or the like Hereinafter, an ink tank packaging container suitable for opening the container under the condition where the atmospheric pressure is changed will be described below.

FIGS. 8A and 8B are views showing such a container.

As shown in the figure, in the above-described type of ink tank, the air communication port and the ink supply port are closed by seal members 16 and 15, respectively.
Ink absorbers 74 and 75 are arranged at positions facing each other with the seal members 15 and 16 interposed therebetween.

The absorbers 74 and 75 absorb the ink that has accumulated in the buffer portion of the ink tank at the time of opening and flows out of the ink supply port. Therefore, it is necessary to absorb the ink faster than the ink flows from the supply port. It is desirable to have an ink absorption speed higher than the speed at which the ink flows out.

The speed at which ink flows from the ink tank 11 is determined by the configuration of the ink tank 11 (particularly, the density of the absorber, the height of the ink tank, etc.) and the properties of the ink.

An ink absorber 75 is also provided between the ink tank and the inner box. The ink absorber 75 has a front-back difference in its surface state, one has a flat state and the other has a mesh-like projection. In other words, the area in contact with a flat surface is different on the front and back. The ink absorbency remains unchanged. The surface having a smaller contact area is arranged on the ink tank side. Thereby, when the seal for the ink tank 11 is opened, even if the ink leaks from the ink supply port or the air communication port due to severe distribution conditions, the ink is instantly sucked by the three absorbing members. Become. In addition, the ink tank 11 is in contact with the packing material and is provided with an ink absorber on the surface where the ink drips under the influence of gravity at the time of opening. We were able to.

Since the absorber provided above has a small area in contact with the ink tank, it is difficult for the ink to adhere to the ink tank. It is difficult for the ink to be transferred to the ink tank in a stamp state while being held by the absorber.

Therefore, even when the ink tank is opened after severe physical distribution or when the environmental change is large, dripping of the ink from the ink tank can be absorbed by the packing material.

[0038]

As described above, according to the present invention,
It is possible to solve three problems related to opening after the ink tank distribution. (1) Opening order of the ink tank By sticking the seal member of the ink supply port and the outer box of the packing, it is easy to remove the ink tank from the box after the ink tank has been opened inside the box. It has an excellent effect of becoming easier.

(2) Spraying of ink when the seal member is removed By restricting the positional relationship between the seal member, the outer box, and the width of the hole through which the seal member is drawn out of the outer box, and the ink tank, the ink spray can be prevented. Can be reduced.

(3) At the time of opening the ink tank after severe distribution or opening under a change in the outside air environment, ink dripping and ink adhesion to the ink tank are arranged. By specifying the absorption speed and the surface of the ink absorber, it is possible to minimize the influence of ink dripping from the ink tank at the time of opening.

Each of the constituent elements has a great effect if all of them are implemented. However, they may be implemented independently, and in such a case, there is an advantage as compared with the related art.
