Abstract

PURPOSE:To provide a container for liquid consisting of a bag of a flexible sheet material which is easy to handle in transportation or the like and out of which liquid contents held inside can mostly be discharged by suction. CONSTITUTION:A container for liquid is formed by attaching a planar passage member 5 having a plurality of projections 5b on one side of a planar plate. 5a and holes 5c open through the planar plate to a gusseted bag 2 in such a manner as to place the planar passage member 5 at one side 2A of the gusseted bag 2 and at the sides 2B, 2B on two sides of it and by attaching an outlet mouth 3 at a position covered by the planar passage member 5. The planar passage member 5 is plane normally but, when the gusseted bag 2 is filled with a material 13 and expanded to substantially a rectangular parallelepiped, the two ends of the planar passage member 5 are made to curve by the gusseted bag 2 elastically and apply tensions to the gusseted bag 2. This constitution makes the gusseted bag 2 less liable to deformation and makes it easily handled. When the contents are drawn out of the gusseted bag 2, wobbly changes in shape of the gusseted bag are prevented so that the contents of the bag can mostly be discharged by suction.

ていた。2. Description of the Related Art Conventionally, a flexible inner bag made of plastic film or the like is housed in an outer box made of paper, cardboard, plastic or the like, and a spout fixed to the inner bag is placed outside the outer box. There is used a bag-in-box in which liquid contents such as juice are contained in the inner bag after being extended. In this bag-in-box, the spout is usually connected to a connector connected to the pump, and the contents are sucked out from the spout and taken out. The volume inside the bag is designed to decrease. Normally, a four-sided sealed bag was used as the inner bag.

う問題が生じる。However, since the bag-in-box requires an outer box to protect the inner bag,
There was a problem of high cost. Although the cost can be reduced by omitting the outer box, the shape of the inner bag containing the liquid becomes unstable, which causes a problem that the handling becomes difficult.

材料、例えばインキを収容すると、この問題が顕著に生
じてくる。Further, the conventional bag-in-box has a problem in taking out the contents. That is, if the contents of the inner bag are simply sucked out from the pouring outlet, the contents in the inner bag are locally sucked, the inner bag is more likely to be wrinkled, and before the entire contents are taken out, A part of the bag may stick to the spout to confine the contents, or a part of the inner bag may stick to a part of the inner bag to confine the contents at a position away from the spout. There was a problem that things could not be taken out. In particular, when a material having a high viscosity such as ink is contained as the content, this problem becomes remarkable.

留量を十分には少なくできないという問題があった。Therefore, in order to prevent the spout from being blocked by the inner bag, the passage plate having a large number of protrusions formed on one surface of the flat plate portion covers the spout, and the protrusion is on the spout side. An attachment is proposed so that it is located at the position (for example, see Japanese Patent Laid-Open No. 4-242565). In the liquid container disclosed in this publication, even if a part of the inner bag moves toward the spout as the contents are taken out, a part of the inner bag is supported by the flat plate portion of the passage plate, A passage is secured between the convex portions, and the contents can be satisfactorily discharged. However, even in this liquid container, when the inner bag is deformed according to the removal of the contents, the portion of the top plate facing the passage plate of the inner bag is not deformed so as to move uniformly toward the passage plate. However, the contents may be deformed non-uniformly, and the top plate portion of the inner bag may stick to the side surface to trap the contents, which causes a problem that the residual amount in the inner bag cannot be sufficiently reduced.

い。Further, since the passage plate used in the past has a concave portion on the opposite side of the convex portion, there is a problem that the content in the concave portion remains as it is and the residual amount increases. To prevent this problem, a film or the like may be attached to the surface of the passage plate and the entrance of the concave portion on the opposite side of the convex portion may be blocked, but in that case, an extra step of attaching the film is required, and the cost is reduced. The problem of becoming high arises. Moreover, if the convex portion is solid, the concave portion is not formed on the opposite side, and thus the residual amount of the content is small, but in that configuration, a large amount of material for forming the passage plate is required, which also increases the cost. I will end up. Although it is possible to reduce the amount of material by making the protrusions thin, it is not preferable because the passages formed between the protrusions become large and the amount of the contents remaining in this portion increases.

It is an object of the present invention to provide a liquid container which can be handled easily by the above-mentioned constitution, and can be taken out well even for contents such as ink having a high viscosity and which can reduce the residual amount.

内容物を取り出すことができる。Since the liquid container having the above-mentioned structure is composed of a gusset bag, it becomes substantially rectangular parallelepiped when the contents are filled and inflated. At this time, since the planar passage member is not only located on one surface of the rectangular parallelepiped but also extends to the surfaces at substantially right angles to both ends of the rectangular parallelepiped, both ends are elastically curved at substantially right angles by the gusset bag. It will be in the state of being forced. Therefore, in the planar passage member, the portion located on one surface of the cuboid bag having a substantially rectangular parallelepiped shape keeps the surface flat, and the elastically curved portions at both ends apply tension to the gusset bag. As a result, the gusset bag, which has a substantially rectangular parallelepiped shape, is unlikely to be deformed during handling such as transportation and storage, and the storage and transportation of the liquid container filled with the contents is easy without using an outer box. The same handleability as the conventional bag-in-box can be obtained. Next, at the time of taking out the contents, a passage is formed between the convex portions of the planar passage member provided so as to cover the pouring outlet, and the pouring is performed from the through hole formed in the flat plate portion or the peripheral edge of the passage plate. A passage leading to the outlet is formed, and the contents are sucked relatively uniformly from the entire bag. Moreover, at that time, since the surface opposite to the surface provided with the planar passage member is given a tension by the elastic force by the both ends of the planar passage member, it is not deformed unstablely, and the contents are taken out. Accordingly, it moves in the direction of approaching the planar passage member as a whole. Therefore, most of the contents in the bag can be taken out without the bag being deformed unevenly and the contents being confined.

る。In the planar passage member having the above structure, a plurality of tubular convex portions are formed at a constant height on one surface of the flat plate portion. The bag is placed in the bag so that the tubular convex portion is adhered and fixed to the inner surface of the bag so that a passage through which the contents pass is formed between the flat plate portion and the inner surface of the bag and outside the tubular convex portion. Can be secured at all times,
The contents in the bag can be taken out well. Moreover, since both ends of the planar passage member can be elastically curved, by attaching the both ends so that they are elastically curved by the bag, tension can be applied to the bag. In addition, the bag is prevented from being unstablely deformed when the contents are taken out, and the good contents can be taken out. Here, since the flat plate portion side of the cylindrical convex portion is closed and the opening portion at the tip is sealed by the inner surface of the bag, the contents do not enter and remain therein, and the material used is reduced. However, since it is possible to form a large cylindrical convex portion, the passage formed between the convex portions can be made small so that the residual amount in the passage can be reduced, and eventually, the residual amount of the content can be reduced. You can Further, since the cylindrical convex portion formed on the flat plate portion has an open tip, the planar passage member having this configuration can be manufactured at low cost by molding resin.

When the contents are put in and inflated, it has a substantially rectangular parallelepiped shape as shown in FIG. As the sheet material forming the gusset bag 2, a commonly used soft packaging material, for example, a laminated material of resin film is used. However, unlike the conventional bag-in-box, the gusset bag 2 may be used without an outer box, so that the gusset bag 2 having a required strength is used. The layer structure of the laminated material used for the gusset bag is specifically selected in consideration of necessary strength, barrier property, heat sealability, and the like. For example, nylon 15μ
/ Polyethylene 60μ laminated material, polypropylene 60μ
Examples thereof include a laminated material of / Nylon 15μ / Polyethylene 60μ, and if necessary, a metal foil may be put in the laminate. It should be noted that the gusset bag 2 alone composed of the soft packaging material tends to be rounded when inflated, and also tends to be deformed due to the weight of the contents, etc. Since it is reinforced by the member 5, there is no problem.

The planar passage member 5 is made to have a rigidity higher than that of the sheet material forming the gusset bag 2 so that the first surface 2A of the gusset bag 2 can be kept flat, but as shown in FIG. When inflated into a rectangular parallelepiped shape, both ends have elasticity so that they can be bent substantially at right angles and elastically correspondingly. In the present specification, “elasticity” does not necessarily mean elasticity in a strict sense such that the load is completely returned to the original state when the load is released, and is returned to the original state after being deformed as shown in FIG. It means a characteristic having a repulsive force in the direction (arrow B direction).

の円筒状に限らず、角筒状等種々変更可能である。The planar passage member 5 is arranged by pressing the cylindrical convex portion 5b against the inner surface of the gusset bag 2, and the tip of the cylindrical convex portion 5b is adhered to the inner surface of the gusset bag 2 by heat sealing or the like. It is installed. As a result, as shown in FIG. 7, the space 10 in the tubular convex portion 5b is closed by the gusset bag 2, and the contents stored in the gusset bag 2 do not enter therein. On the other hand, the space 11 outside the tubular convex portion 5b is entirely communicated vertically and horizontally between the flat plate portion 5a and the gusset bag 2 and also to the spout 3, and is formed in the flat plate portion 5a. The through hole 5c communicates above the flat plate portion 5a. Thus, this space 11 has a flat plate portion 5a.
A passage which communicates the upper part of the with the spout 3, and is hereinafter referred to as a passage. This passage 11 is a gusset bag 2
It is for flowing the content when sucking and removing the content from the inside through the spout 3, and it is preferable that the content is large in order to facilitate the removal of the content. Since it is a residue, it is better to be small from this point. In consideration of these, the dimensions of the passage 11 (hence, the height and diameter of the cylindrical convex portion 5b, the gap between the adjacent cylindrical convex portions, etc.) are determined. The height, diameter, gap, and other dimensions of the cylindrical convex portion 5b differ depending on the physical properties such as the viscosity of the contents, but generally the height is 1 to 5 mm and the diameter is 5 to 1
0 mm and a gap of about 3 to 6 mm are selected. However, the value is not limited. The shape of the tubular convex portion 19 is not limited to the illustrated cylindrical shape, and various modifications such as a square tubular shape can be made.

As a result, the gusset bag 2 has a substantially rectangular parallelepiped shape as shown in FIGS. At this time,
Since the planar passage member 5 is attached to almost the entire area of the first surface 2A of the rectangular parallelepiped, it is kept flat. Further, since the curved end portions of the planar passage member 5 have elastic force in the direction indicated by the arrow B, a force in both end directions (arrow B direction) is applied to the end faces 2B, 2B of the gusset bag 2. The tension is applied to the gusset bag 2 in the directions indicated by arrows D and E. Therefore, the surface (hereinafter referred to as the second surface) 2C facing the first surface 2A is also held by a flat or curved surface having a large radius. Thus, even if the gusset bag 2 is made of a soft sheet material, the gusset bag 2 is not deformed in an unstable manner and the whole is kept in a substantially rectangular parallelepiped shape. In this state, storage, transportation, etc. of the liquid container 1 are performed. Here, as described above, since the entire liquid container 1 is kept in a substantially rectangular parallelepiped shape and is unlikely to be deformed, it is easy to handle such as storage and transportation. If necessary, one liquid container 1 may be packed and handled in one box, or a plurality of liquid containers 1 may be packed and handled in one box.

At this time, the contents 13 in the gusset bag 2 may be the through holes 5c of the flat plate portion 5a of the planar passage member 5 or the flat plate portion 5a.
Into the passage 11 below the flat plate portion 5a through the peripheral edge of the passage and is sucked into the spout 3 through the passage 11. Therefore, the contents on the planar passage member 5 are relatively uniformly sucked from a large area, and moreover, the upper surface of the gusset bag 2, that is, the second surface 2C.
Is pulled to both sides as indicated by an arrow E, the second surface 2C of the gusset bag 2 has a two-dot chain line 2 as the inner volume of the gusset bag 2 decreases as the contents are sucked out.
As indicated by C ', the plate is lowered in a substantially flat state and substantially parallel to the planar passage member 5. Thus, the contents in the gusset bag 2 are well sucked out from the spout 3. Moreover, since wrinkles do not easily occur on this surface, it is unlikely that the contents are locally confined in the gusset bag 2. Thus, the contents are sucked until the second surface 2C of the gusset bag 2 comes into close contact with the entire upper surface of the planar passage member 5, and most of the contents contained in the gusset bag 2 are sucked and taken out. As described above, in the liquid container 1, the upper surface 2C of the gusset bag 2 descends in a state of being substantially parallel to the bottom surface according to the suction of the contents, so that the displacement of the upper surface 2B is stable, and therefore, There is little variation between products, and reproducibility is extremely high. Therefore, in any product, the contents can be discharged well and the residual amount can be reduced.

It is also possible to make the and the planar passage member 5 into an integral structure. 10 and 11 show an embodiment in that case,
The principal part of the planar passage member 15 provided with the spout is shown.
The planar passage member 15 also has a flat plate portion 15a, a plurality of cylindrical convex portions 15b formed so as to project on one surface of the flat plate portion 15a, and a plurality of through holes 15c formed in the flat plate portion 15a. Which has a flat plate portion 15a
In addition, a raised portion 15d having substantially the same height as the cylindrical convex portion 15b is formed, and a spout 15e is integrally formed at the center thereof. Further, on the side opposite to the spout 15e, a cylindrical portion 15f is provided.
And a groove 15g is formed in the tubular portion 15f.
The planar passage member 15 having this structure is attached to the inner surface of the gusset bag 2 by heat-sealing the tips of the raised portion 15d and the tubular convex portion 15b, and is used in the same manner as the embodiment of FIG.
Here, when the inner surface of the gusset bag is deformed and approaches the spout 15e, the tubular portion 15f supports the part and prevents the spout 15e from being blocked. The planar passage member 15 having a structure in which the spout is integrated with the planar passage member has the advantages that the number of parts constituting the liquid container can be reduced and the cost can be reduced.

とができるという効果を有している。As described above, according to the liquid container of the present invention as set forth in claim 1, the planar passage member is attached to one surface of the gusset bag, and when the gusset bag is filled with the contents and inflated, Since both ends of the sheet-like passage member are elastically curved, one surface of the sheet-like passage member can be kept flat by the sheet-like passage member in the state of being filled with the contents, and the surface opposite to it can be formed by the sheet-like passage member. By applying the tension, it can be kept flat, and the whole can be made into a substantially rectangular parallelepiped shape and difficult to be deformed. Therefore, the outer box can be omitted without impairing the handleability, and the cost can be reduced as compared with the conventional bag-in-box. Further, when the contents are taken out, the gusset bag can be sucked from a wide portion of the sheet-like passage member, and a tension is applied to the opposite surface to prevent wrinkles from occurring, so that the contents are sucked out. It is possible to take out the contents in a stable manner at all times without causing unstable deformation, and it is possible to extremely reduce the residual amount in the gusset bag.

It can be taken out satisfactorily and with a very small residual amount. Moreover, since the convex portion formed on the planar passage member is hollow with the flat plate portion side closed and the tip open, the tip of the convex portion is attached to the inner surface of the gusset bag to attach the contents therein. Since it is hollow and does not stay, and because it is hollow, a large convex portion can be formed without increasing the amount of material used to make the passage between the convex portions small, and the amount of contents remaining in that passage can be reduced, The residual amount of the product can be reduced, and in manufacturing, it has an effect that it can be manufactured in one step by molding without using many materials, and can be manufactured at low cost.
