Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package.

[0002]

2. Description of the Related Art A pillow package is generally used as a package for storing a portable wet tissue or a sterilizing cleaner. That is, as shown in FIG. 3, the center seal portion 2 is located at the center of the bottom surface of the package 1.
Then, as shown in FIG. 2A, an outlet 3a from which the packaging film 3 has been removed to a predetermined size is provided at the center of the top surface.
While being formed, a film-like lid 4 is adhered to the packaging film 3 so as to cover the outlet 3a. One end 4a of the lid 4 is firmly adhered to the packaging film 3, and an adhesive that can be repeatedly adhered and fixed is applied to the remaining peripheral portion.

As a result, the lid 4 normally covers and closes the outlet 3a, and when used as shown in FIG. 1A, the lid 4 is opened to open the outlet 3a. And take out wet tissue. After use, the package 1 is sealed by attaching the lid 4 to the packaging film 3.

[0004]

However, in the above-mentioned conventional package, the lid 4 is adhered to the packaging film 3 using an adhesive which can be repeatedly adhered, so that the package 1 is sealed. Therefore, by repeatedly opening and closing the cover, the adhesive strength of the adhesive is reduced, and the cover 4 may not be completely bonded. Then, there is a possibility that the packaged product dries and becomes unusable.

Further, in consideration of the manufacturing process, a process of forming a hole at a predetermined position of the packaging film to form an outlet and bonding the lid while aligning the outlet with the hole becomes complicated. Moreover, part of the lid 4 is firmly adhered to the packaging film, and the remaining part is coated with an adhesive that can be repeatedly bonded, so that different adhesives are applied on the same surface, which makes the process complicated. It is also possible to use an adhesive that can be repeatedly adhered to the entire periphery, but in that case, the lid is completely separated from the package at the time of use, so there is a possibility that the lid may be lost or fall to the ground or the like and become dirty. is there. And if it falls, there are hygiene problems.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and an object of the present invention is to maintain the same degree of sealing as in the initial state even if opening and closing are repeated many times with a simple structure. While making it easy to take out the contents when opening,
An object of the present invention is to provide a package in which a member (male and female fasteners) for closing the package is separated from the package at the time of opening and is not lost or stained.

[0007]

In order to achieve the above-mentioned object, in a package according to the present invention, both side edges of a packaging film formed into a cylindrical shape are bonded to form a center seal portion, and the center seal portion is formed. It is assumed that a pillow-type package is formed by heat-sealing the openings at both ends in the direction crossing the seal portion. And the said center seal part is arrange | positioned along the side edge vicinity of a package. Furthermore, the center seal portion is made openable and closable by interposing male and female fasteners, and the male and female fasteners are closed to easily seal.

Here, in the case of a normal pillow type package, the center seal portion is bonded by heat sealing or the like, but the present invention does not necessarily require heat seal. In other words, it is also possible to simply bond the polymerized ends with male and female fasteners. Of course, the films may be heat-sealed. In that case, the male and female fasteners are located inside the heat-sealed portion, and in that case, the virginity of the product is guaranteed, which is more preferable.

Further, with the above configuration, the package is opened by opening the male and female fasteners, and the package is closed by closing. And the male and female fasteners do not decrease the sealing degree even when used repeatedly. Also, since the male and female fasteners are each bonded to the packaging film,
It does not fall when opened. Furthermore, since it is located near the side edge of the package, the package can be opened to a greater extent than that provided at the center.

[0010] Further, when the object to be packaged is a wet one such as a wet tissue or a disinfecting cleaner as in the embodiment, there is a possibility that the liquid may seep and accumulate in the package. Then, if the side surface is opened, the liquid leaks out, which is not preferable. Furthermore, when a plurality of items to be packaged are laminated and the mutual frictional force is large,
Opening the side and trying to pull it out sideways may result in multiple pullouts at the same time.

However, by installing the male and female fasteners on the upper surface as in the present invention, the upper surface is opened,
Even if liquid is present in the package, there is no risk that the liquid will leak out when opening. Further, in the case where the article to be packaged is a stack of a plurality of articles, if the articles are taken out one by one from the top, the second and subsequent articles will not be taken out together. This can also be said when the packaged item is a strange food or other food product.

[0012]

FIG. 1 shows an example of an embodiment of a package according to the present invention. As shown in FIG. 1, the package 10 covers a packaged object 13 by forming a single package film 12 into a cylindrical shape. Then, the center seal portion 14 is formed by joining the film overlap ends. Further, both ends of the cylindrical packaging film 12 are heat-sealed to form a top seal portion 15. Thereby, the package 10 is sealed.

In the present embodiment, the packaged object 13 is
A laminate of a large number of wet sheets, such as a wet tissue or a disinfecting cleaner, is used. Since the height h of the packaged object 13 is high, the gusset 16
Is formed and the peripheral portion of the top seal portion 15 is folded into the inside, so that the width D of the top seal portion 5 is reduced.
Is equal to the width D ′ of the main body portion of FIG.

Here, in the present invention, in the conventional pillow package, the formation position of the center seal portion 14 formed at the center is shifted laterally and arranged along the vicinity of the side edge 10a of the package 10. .

Further, as shown in FIG. 1B, the male and female fasteners 20 are mounted on the center of the center seal portion 14 as shown in FIG. In FIG. 1B, for convenience of illustration, the center seal portion 14 is shown in an upright state. However, in reality, the center seal portion 14 is lying down and is parallel to the surface of the packaging film 12.

As shown in FIG. 2, the male and female fasteners 20 include a male fastener 20a and a female fastener 20b.
It is composed of The male fastener 20a is composed of a belt-like portion 24 made of a thermoplastic synthetic resin such as polyethylene and polypropylene, and a protruding projection formed integrally on the center line of the belt-like portion 24 and having a wide upper portion. And a first jaw 25a. Further, the female fastener 20b is composed of a belt-like portion 24 similar to the male fastener 20a, and a second jaw 25b integrally formed on the center line of the belt-like portion 24 and having a concave groove at the center thereof. It is configured. And these first,
The male and female fasteners are closed when the second jaws 25a and 25b are engaged.

To manufacture the package 10, the band 24 of the male fastener 20a is thermally bonded to one side edge of the packaging film 12, and the band 2 of the female fastener 20b is bonded.
4 is thermally bonded to the other side edge of the packaging film. Then, when the bag is formed into a cylindrical shape, or after that,
By mixing a and 25b, the side edges of the packaging film 12 are bonded together. The other steps are the same as in the ordinary pillow packaging.

In the above-described embodiment, both side edges (center seal portion 14) of the packaging film 12 are not heat-sealed. However, the present invention is not limited to this.
The overlapping end of the packaging film may be heat-sealed. In that case, the seal is naturally performed outside the male and female fasteners 20. Further, in the above-described embodiment, the gusset is formed, but the present invention is not limited to this, and a package without the gusset may be used. Further, the article to be packaged is not limited to a wet tissue as described above, but can be applied to various items.

[0019]

As described above, in the package according to the present invention, male and female fasteners are provided in the center seal portion, and the package is opened from the center seal portion.
Even if opening and closing are repeated many times with a simple configuration, the same degree of sealing as in the initial state can be maintained. In addition, since the center seal portion is located along the vicinity of the side edge, the center seal portion can be opened widely widely at the time of opening, and the contents can be easily taken out. Furthermore, since the member for closing the package (male and female fasteners) is bonded to the packaging film, the male and female fasteners are detached from the package at the time of opening and lose or become dirty. Nothing to do.
