[0002]

2. Description of the Related Art Conventionally, as a material for a packaging body for packaging articles, a soft synthetic resin material formed into a film shape or a multilayered material thereof, and a metal vapor deposition layer (hereinafter Collectively referred to simply as a synthetic resin film) and the like are widely used. Since this synthetic resin film is highly flexible and easy to process, various packaging bodies having functions such as airtightness, waterproofness, and light-shielding properties have been devised according to the properties and shape of the article to be packaged. . For example, a gusset-folded package formed by forming a rectangular tubular body with a synthetic resin film, and joining both ends of the tubular body with both side surfaces folded inward is used for various food and tissue paper packages. It is used for packaging various products.

By the way, when the content is a wet tissue such as a sterilizing liquid agent which evaporates and is continuously used while being taken out little by little, the opening for removing the content and this The package is provided with a detachable lid that can be opened or closed, and the opening is closed by the lid every time a part of the contents is taken out to prevent liquid evaporation. Further, in the case where such a package is formed from the above-mentioned synthetic resin film, as a lid, from the viewpoint of cost and disposal after use, an adhesive material that can repeat adhesion and peeling is used on one side of the synthetic resin film. A seal member applied to the surface of is preferably used.

[0004]

However, such a conventional package is poor in rigidity, and if there is a space between the article to be packaged and the package, the surface of the package is freely deformed, and There was a problem that the appearance was spoiled. In particular,
In the case where the above-mentioned wet tissue is the content, when the content decreases due to use, a space is created between the package and the content, and the surface of the package becomes freely deformable, There is a problem that the package and the sealing member, which is the lid, cannot be brought into close contact with each other and adhered, and it becomes difficult to seal the opening.

In view of such conventional problems, the present invention has
It is an object of the present invention to provide a package made of a soft material in which surface deformation is suppressed.

[0006]

Therefore, in the invention according to claim 1, a reinforcing member having a rigidity higher than that of the packaging member is formed by covering the inside of the bag-shaped packaging member with synthetic resin. , So as to contact the inner surface of the packaging member. In the package having such a configuration, the shape of the packaging member is retained from the inside by the reinforcing member. Further, the reinforcing member in which paper is coated with a synthetic resin has a low manufacturing cost and is excellent in durability.

The bag-shaped packaging member has an upper surface and
And a bottom surface and both side surfaces folded inside each other

Shrink. Then, in order to continuously use while taking out the contents little by little, an opening is provided on the upper surface of the bag-shaped packaging member, and a detachable seal member for opening and closing the opening is attached while the inside of the packaging member is attached. , A paper coated with synthetic resin, a top plate in contact with the top surface of the packaging member, and both sides
And a reinforcing member having a rigidity higher than that of the packaging member, and a hole corresponding to an opening of the packaging member is provided in the reinforcing member. .

Thus, even after the contents are reduced, the shapes of the upper surface and both side surfaces of the packaging member are maintained and the sealing member is smoothly attached and detached. In the invention according to claim 2 , the reinforcing member is fixed to at least a part of the inner surface of the packaging member so that the positional relationship between the reinforcing member and the packaging member is always constant.

[0009]

Further, in the invention according to claim 3 , a folding ruled line which is substantially parallel to the folding of the side surface of the packaging member having the gusset structure is provided on the side plate, and a bend having a restoring property is provided along the folding ruled line. To enable. As a result, when the remaining contents are taken out, the packaging member and the reinforcing member are easily contracted downward in accordance with the decrease in the contents, and after the taking out, the shape of the packaging member is maintained by restoring the reinforcing member.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of the package of the present invention. In the packaging body 1, the packaging member 2 for packaging the contents is formed by folding one sheet shown in FIG. 2 along a dotted line, joining sides A and B, and folding the upper surface 3 and the lower surface 4 inward with each other. A side wall 5 and a side surface 6 are formed, and sides C and D forming one end and the other end of the side wall are joined and closed to form a gusset fold structure. The inner surface of this gusset fold structure is formed into a substantially rectangular parallelepiped for easily holding contents.

The material of the packaging member 2 is not particularly limited,
PET (polyethylene terephthalate), CPP, etc., when the content contains a substance that evaporates, or when it is necessary to block the entry of air from the outside to protect the content.
(Unstretched polypropylene), ONY (stretched nylon),
A synthetic resin film having a multilayer structure using LLDPE (Linear Low Density Polyethylene) or Al thin film as a material is preferably used. As a specific example of such a synthetic resin film, for example, PET: 12 μm / A in order from the outside.
l Thin film: 7 μm / CPP: 30 μm layer structure, ONY: 12 μm / Al thin film: 7 μm / LLD
An example is one having a layer structure of PE: 40 μm.

The upper surface 3 of the packaging member 2 is provided with an oval or elliptical opening 7 for taking out the contents, and a sealing member (tack label) for closing the opening 7 is provided.
8 is attached. An adhesive is applied to the surface of the seal member 8 facing the packaging member 2. This allows the opening 7 to be opened and a part of the contents to be taken out, and then the opening 7 can be closed again to store the rest.
As the material of the seal member 8, it is preferable to use the same material as the packaging member 2 in terms of manufacturing cost and disposal. It should be noted that the end portion of the seal member may be provided with a portion (peel tab) to which no adhesive is applied in order to facilitate peeling.

A reinforcing member 9 is arranged inside the packaging member 2. The reinforcing member 9 is formed by bending a single plate material as shown in FIG. 3 (a) at a substantially right angle along the folding ruled line 10 and then by gently bending it inwardly along the folding ruled line 11 to obtain the structure shown in FIG. 3 (b). Top plate 12 and side plate 1 as shown
It is composed of 3 and 14. The top plate 12 is provided with a hole 15 corresponding to the opening 7 of the packaging member 2, through which the contents can be taken out. Further, as shown in FIG. 4, a bottom plate 16 may be provided in addition to the top plate 12, the side plates 13 and 14. The upper surface plate 12 and the side surfaces 13 and 14 contact the upper surface 3 and the side surfaces 5 and 6 of the packaging member 2, respectively,
The shape of the packaging member 2 is maintained. Further, since the side surface plates 13 and 14 are provided with folding ruled lines 11 that are substantially parallel to the folding inward of the side surfaces 5 and 6 of the packaging member 2, the side plates 13 and 14 can be bent along the folding ruled lines 11.

The reinforcing member 9 is made of paper coated (laminated) with a synthetic resin. Specifically, PVC is used.
(Polyvinyl chloride), PP (Polypropylene), PE
A shrink film made of (polyethylene) or the like and shrinkable by heat is used to shrink-wrap thick paper (card paper or the like) as a whole (including end faces). As described above, the reinforcing member 9 whose entire surface including the end surface of the paper is completely covered with the synthetic resin does not penetrate into the paper even when the content of the package contains water or oil. Since it does not exist, it is possible to stably maintain a predetermined strength. Both of the crease lines 10 and 11 described above are formed by mechanical pressing on paper before shrink-wrapping.

Since the synthetic resin covering the side plates 13 and 14 has elasticity, the side plates 13 and 14 are bent along the crease line 11 by the downward load indicated by the X arrow in FIG. 1 and released from the load. If it is done, it will be restored to the almost original state. Therefore, even if the contents such as wet tissues are reduced, the contents at the bottom of the packaging member 2 can be easily taken out from the opening 7 by bending the side plates 13, 14. Also,
After the contents are taken out, the reinforcing member 9 is restored to its original state, so that the upper surface plate 12 of the packaging member 2 is always in contact with the upper surface 3 of the packaging member 2 and its deformation is suppressed. Thus, when the opening 7 of the packaging member 2 is closed by the sealing member 8, the both can be easily brought into close contact with each other to seal the inside, and at the same time, the outer appearance of the package 1 can be kept beautiful.

It is conceivable to use a hard synthetic resin or the like as the reinforcing member 9, but if the elasticity is too strong, it may be difficult to take out the reduced contents, or it may be damaged by fatigue due to repeated expansion and contraction. To be Also, from the viewpoint of cost and disposal, paper coated with synthetic resin is excellent. The reinforcing member 9 may be separated from the packaging member 2, but may be integrally formed. In the configuration in which the two are separated, the contents are placed on the reinforcing member 9 and conveyed, and the packaging member 2 wraps the contents, so that the packaging work can be performed efficiently and easily.

On the other hand, if both are integrally formed, the positional relationship between them is stabilized, and the shape of the packaging member 2 can be held more reliably. When the reinforcing member 9 and the packaging member 2 are integrally formed, a part of both may be joined by an adhesive. However, the material of the shrink film covering the reinforcing member 9 and the surface of the packaging member 2 facing each other. If they are made of the same material, it is possible to attach them by heating and fusing them.
For example, the above-mentioned packaging member having the CPP layer on the inner surface is a reinforcing member coated with paper by a PP-based shrink film, and the packaging member having the LLDPE layer on the inner surface is a reinforcing member coated with a paper by a PE-based shrink film. Can be easily fused by heating.

Alternatively, the reinforcing member 9 may be formed by heating and fusing the surface of the packaging member 2 and a sheet piece made of the same material as the packaging material 2 with a thick paper sandwiched therebetween.
When the packaging member 2 and the reinforcing member 9 are integrally formed in this way, as shown in FIG.
Even with this configuration, since the upper surface of the packaging member 2 can always be tensioned, the sealing member can be adhered and adhered when closing the opening 7.

In each of the above examples, the packaging member 2 is provided with the opening 7 for taking out the contents.
The package of the present invention may use a packaging member without such an opening, and is effective in maintaining its shape and maintaining a beautiful appearance.

[0021]

As described above, according to the first aspect of the present invention, by applying tension to the packaging member from the inside, the appearance of the packaging can be kept beautiful. Further , since the tension can be maintained on the upper surface of the packaging member even after the content is reduced, the seal member can be firmly attached to the opening of the packaging member and securely attached. As a result, even if the substance that evaporates is contained in the contents, the inside of the package can be sealed after the necessary amount is taken out, and there is an effect that it can be stored for a long time. . And according to the increase and decrease of contents
The packaging material can be expanded and contracted in the vertical direction, reducing the contents.
Even if it does, the contents remaining without losing the appearance of the packaging material
There is an effect that can be taken out. In addition, the package
Applying tension even in the vertical direction of the packaging member,
The effect is that it can be held more firmly.

According to the second aspect of the invention, since the positional relationship between the reinforcing member and the packaging member is always constant, there is an effect that tension can be applied to the packaging member more stably.

According to the third aspect of the invention, the tension in the vertical direction of the packaging member is adjusted, and even if the content is reduced, the appearance of the packaging member is maintained and the remaining contents are easily removed. Can be taken out. In addition, after the contents are taken out, the side plate is restored to its original state, so that there is an effect that tension can be continuously applied to the upper surface of the packaging member.
