Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package wrapped with a wrapping film, and more particularly to a form in which a wrapping film adheres to a packaged object so as to stick to it. The present invention relates to a package such as a tape cassette in which one or a plurality of packaged items are simultaneously packaged.

[0002]

2. Description of the Related Art Of the products lined up at the stores of various recent retail stores, for example, magnetic tape cassettes and the like, which have a constant shape and are relatively small, have a dust-proof or moisture-proof product. In addition, in consideration of aesthetics, the outer surface is wrapped with a transparent or translucent cellophane, polyethylene, polypropylene, polyvinyl chloride, or a wrapping film such as a film obtained by coating polyvinylidene chloride on these. The magnetic tape cassette or the like is shipped as a packaged package, or an appropriate number of products are packaged together and displayed as one package for bulk sale in stores.

Conventionally, a packaged product (product) wrapped with this type of wrapping film is naturally peeled off when the package is taken out, but most of the inside of the wrapping film is peeled off. In this case, for example, as shown in FIG. 17, a tear tape 2 is generally provided, and a structure that makes it easy to take out the packaged object 10 is generally adopted.

That is, the tear tape 2 can be cut by appropriately tearing the wrapping film 1 by pulling the end 2a exposed on the surface thereof. Further, a notch 3 is provided along the tear tape 2 in the vicinity of the exposed end portion 2a of the tear tape 2 to facilitate tearing. With such a configuration, the wrapping film 1 can be torn from the end portion 2a along the tear tape 2, and as a result, the wrapping film 1 is largely torn or divided into two parts. Can be stripped from the product.

[0005]

As for such a wrapping film, a wrapping method generally called shrink wrap is often used. In this shrink wrapping, the wrapping film is appropriately stretched when it is attached to the packaged product (product), or the product is wrapped by the material of the film and then heated at an appropriate temperature. The shrinkage force allows the film to be packaged in good contact with the product in good appearance. The fact that the wrapping film adheres to the product in this way means that
Since peeling is difficult when the film is opened, in the past, the tear tape has been devised as described above, and this tear tape has been a very effective means.

However, in order to attach the tear tape to the inside of the wrapping film, not only a dedicated attachment device and attachment process are required, but also the tear tape needs to be stronger than the wrapping film in terms of its function. Yes, the cost for tear tape was high.

Further, among the portions remaining after tearing the wrapping film with the tear tape, as shown in, for example, FIG. 17, the small area a can be easily removed depending on the position where the tear tape is arranged. The large area B is the part that remains after taking the tear tape,
There is a problem that it takes a lot of time to peel off the remaining portion.

For this reason, a weak adhesive portion that is easy to peel off is provided on the body seal portion where both ends of the wrapping film are overlapped and adhered, and the portion that remains after tearing the wrapping film with tear tape is from this weak adhesive portion. An invention has been proposed in which the wrapping film can be easily peeled off by peeling it off greatly (actually
32066).

However, since the invention proposed in Japanese Utility Model Laid-Open No. 3-32066 still provides a tear tape, it requires an attaching device and an attaching step for providing the tear tape, and The cost of tear tape was also high. Furthermore, since the wrapping film is peeled off by a two-step operation of tearing the tear tape and peeling off the weakly bonded portion, there is a problem that the peeling operation is troublesome.

On the other hand, a bonding portion and a non-bonding portion where the wrapping films are bonded to each other are provided on the body seal portion,
By providing a plurality of linear perforations on the wrapping film that constitutes the outside of the body seal portion, a packaging body that allows the wrapping film to be peeled off without using tear tape has been proposed (Actual Kaihei 4- 84166).
According to this wrapping body, when the film is pulled up by putting a finger on the non-adhesive part of the body seal part, the edge part of the body seal part is torn and the perforations near it are cut off. Since it tears along the film, the film can be easily removed without using tear tape.

By the way, in the package described in Japanese Utility Model Laid-Open No. 4-84166, the wrapping film is peeled off from the non-adhesive portion. Therefore, it is necessary to increase the area of the non-adhesive portion in order to break the lapping film. There is. However, if the non-bonded portion is made large, the tightness of the package will not be maintained.

In view of the above circumstances, the present invention does not require a special device or member, and the lapping film is largely torn at the time of opening by one operation, so that the object to be packaged can be easily taken out, and further, the sealing property thereof can be obtained. It is an object of the present invention to provide a package capable of holding even the above.

[0013]

The package according to the present invention comprises:
An outer surface of a packaged object is covered with a wrapping film, and a package body is provided with a body seal part in which both ends of the wrapping film are overlapped and adhered to each other. In the package body, an end of the wrapping film on the upper side of the body seal part. At the edge, at the edge of the lower wrapping film, at the edge of the upper wrapping film, at the edge of the upper wrapping film, and at the edge of the upper wrapping film So as to be orthogonal or skew,
A cut portion formed in the vicinity of the non-adhesive portion via a part of the body seal portion, and the upper side adjacent to the opposite side of the non-adhesive portion on the side where the cut portion is provided. It is characterized in that it has a weakly bonded portion that is weakly bonded to the end portion of the lower wrapping film that extends for a predetermined length along the edge of the wrapping film.

Here, the cut portion is formed "close to" the non-bonded portion via the body seal portion, that is, the cut portion does not come into contact with the non-bonded portion and the cut portion does not contact the non-bonded portion. Slightly from the non-bonded part through the part (preferably 2 to 3 m from the non-bonded part)
m) It means that it is provided at a distant position.

Further, in the package according to the present invention, the unsealing portion composed of the non-adhesive portion, the notch portion and the weakly adhesive portion is provided in two.
Alternatively, the weakly adhered portions may be provided inside so as to face each other.

Here, "providing the weakly bonded portions so as to face each other with the weakly bonded portions facing each other" means both the case where the weakly bonded portions of the two opening portions are provided with a space therebetween and the case where the two weakly bonded portions are shared. It includes cases.

Furthermore, in the package according to the present invention, in the above package, a cutout portion is provided in the vicinity of a position where an edge of the lower lapping film intersects with the extension line of the cut portion. May be further provided.

Further, in each of the above-mentioned packages, the non-adhesive portion may be provided with a mark for clarifying that it is the non-adhesive portion, and the non-adhesive portion or the vicinity of the non-adhesive portion may have an unsealing direction. You may attach the mark which indicates.

[0019]

In the package according to the present invention, the wrapping film is pulled from the cut portion when the end portion of the non-adhesive portion described above is squeezed with a finger, a nail or the like, and the end portion is pulled in a direction substantially orthogonal to the body seal portion. At the same time as tearing, the weakly bonded portion of the body seal portion peels off, and spreads in a direction substantially orthogonal to the body seal portion. As a result, the wrapping film is opened wider, and the film can be peeled off very easily so that the article to be packaged is almost completely exposed.

Further, since the weakly adhered portion is provided, the body seal portion can be largely peeled off without increasing the area of the non-adhered portion, whereby the tightness of the package can be maintained.

Further, if two unsealing portions including the above-mentioned non-adhesive portion, notch portion and weak adhesive portion are provided so as to face each other with the weak adhesive portion facing inside, any non-adhesive portion can be provided. It is more preferable because the wrapping film can be opened.

Furthermore, if a notch is further provided in the vicinity of the edge of the lower lapping film, where this edge intersects with the extension of the notch, the upper lapping film is peeled off. By tearing the lower wrapping film from this notch, the wrapping film can be opened further and the wrapping film can be peeled off more easily.

Further, if a mark is provided to clarify the position of the non-adhesive portion, the peeling direction, etc.,
It is more preferable because the position where the wrapping film is peeled off becomes clear.

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 diagram showing a first embodiment of a package according to the present invention in which an audio cassette is a package.

As shown in FIG. 1, a wrapping film 1
Is a packaged object 10 whose both ends are audio cassettes.
The narrow surface of the rectangular parallelepiped (stored in the storage case) is superposed at approximately the center and heat-welded to form the body seal portion 4 (this body seal portion will be shaded below). display). Both ends of the body seal portion 4 are formed so as to reach the side seal portion 13 by being welded together with the film bent on the other surface.

The body seal portion 4 and the side seal portion, which are overlapping portions of both ends of the wrapping film 1, are provided.
After wrapping the packaged object 10, 13 is welded by appropriate heating or the like.

Further, at a position near the end in the longitudinal direction of the body seal portion 4, a part of the end edge of the body seal portion 4 of the wrapping film 1 on the upper side is included, and an edge portion extending along the end edge, that is, A non-adhesive portion 5 is formed in the end edge portion 4A at least up to the end edge of the body seal portion 4 of the lapping film 1 on the lower side. Here, it goes without saying that the non-adhesive portion may be provided beyond the edge of the body seal portion 4. In addition,
The length of the non-bonded portion 5 is preferably 10 to 50 mm, but most preferably about 20 mm. At a position close to the non-adhesive portion 5, at least one cut portion 6 is formed orthogonal to the edge portion 4A of the upper film 1. It is preferable that the cut portion 6 be separated from the non-bonded portion 5 by about 2 to 3 mm. Further, the lower lapping film, which is adjacent to the side of the non-adhesive portion 5 opposite to the side where the cut portion 6 is provided and extends for a predetermined length along the edge 4A of the upper lapping film, is provided. A weakly adhered portion 7 is formed which is weakly adhered to the end of the.

The weakly bonded portion 7 is the wrapping film 1
In the portion corresponding to the weakly adhered portion 7 of No. 3, halftone dot printing or stripe-shaped printing is performed from the back surface of the wrapping film 1, and when heat is applied to the body seal portion 4 to adhere, the halftone dot printing or stripe-shaped printing is performed. It is formed by preventing the welding of the entire surface of the body seal portion 4. As described above, the weakly bonded portion 7 is formed by mixing the bonding area where the wrapping films are bonded and the non-bonding area where the wrapping films are not bonded, but it is not always necessary to uniformly mix the bonding area and the non-bonding area. Instead, for example, as shown in FIG. 15, the scattered density of the bonding area (black spots) of the weakly bonded portion 7 is changed, and further, as shown in FIG. 16, the lapping film on the upper side of the weakly bonded portion 7 is used. The region near the edge 4A of 1 may be a non-adhesive stripe, and the weakly adhering part 7 may be formed with the adhering region and the non-adhesive region unevenly distributed. Further, the weak adhesion portion 7 can be formed by printing the weak blocking ink on the portion corresponding to the weak adhesion portion 7 of the wrapping film 1.

First, the end of the non-adhesive portion 5 is squeezed with a finger or a nail, and the finger or the like is moved in the direction of arrow A in FIG.
As a result, as shown in FIG. 2, the upper and lower films of the body seal portion 4 between the non-adhesive portion 5 and the cut portion 6 are lifted.

Then, as shown in FIG. 3, when the end 4a of the peeled upper film is pulled in the direction of arrow A, the tear from the notch 6 widens and a part of the weakly bonded portion 7 peels off. The upper film is lifted from the lower film. Furthermore, when the end 4a of the film is pulled upward in the direction of arrow A, the tear from the notch 6 further spreads and the weakly bonded portion 7 is further peeled off. Further, when the end portion 4a of the peeled upper film is pulled in the direction of the arrow A, the wrapping film 1 is opened further as shown in FIG.

The tear opening formed by such tearing can cause a tearing action so as to surround the wrapping film 1 by pulling and tearing the end 4a of the upper film, whereby the wrapping film 1 is cut. Will be opened wider. Thus, the film 1 can be peeled off very easily so that the package 10 can be exposed almost completely.

Furthermore, since the cut portion 6 is formed in the vicinity of the surface of the packaged body 10 on which the side seal portion 13 is formed, the wrapping film left on the surface on which the side seal portion 13 is formed. 1 is the remaining wrapping film 1
It can be peeled off very easily by pulling in the direction of removing.

Here, in the conventional case, of the wrapping film divided by the tear tape, the portion left on the side opposite to the tearing direction was relatively difficult to remove from the package. In comparison with the above, not only the extremely effective peeling operation can be performed by one operation, but also the tear tape itself is not required to be provided, and the packaging can be extremely advantageous in terms of cost.

Next, a second embodiment of the present invention will be described. FIG. 5 is a diagram showing a second embodiment of the packaging body according to the present invention. In FIG. 5, the wrapping film 1
Since the packaging state, the non-adhesive part 5, the notch part 6 and the weakly adhered part 7 are the same as those in the first embodiment of the present invention described above, detailed description thereof is omitted here.

In the second embodiment of the present invention, the first unsealing portion composed of the non-adhesive portion 5, the cut portion 6 and the weak adhesive portion 7, the non-adhesive portion 5 ', the cut portion 6'and the weak adhesive portion. The second unsealing portion including the portion 7'is provided so as to face each other with the weakly adhesive portions 7 and 7'inside.

As described above, the first unsealing portion including the non-adhesive portion 5, the notch portion 6 and the weak adhesive portion 7, and the first unsealing portion 5 ', the notch portion 6'and the weak adhesive portion 7'. By providing the two opening portions, the wrapping film 1 can be opened from any of the non-adhesive portions 5 and 5 ', so that the wrapping film 1 can be opened more easily.

In the above-described second embodiment of the present invention, the first and second opening parts are provided separately, but like the third embodiment of the present invention shown in FIG. It is also possible to make the weakly bonded portions 7 and 7'of the unsealed portion a common weakly bonded portion. By making the weakly bonded portions 7 and 7'common in this way, it is possible to save the labor of peeling the adhesively bonded portions between the weakly bonded portions 7 and 7'compared to the second embodiment of the present invention. It is more preferable.

Next, a fourth embodiment of the present invention will be described. FIG. 7: is a figure showing 4th Embodiment of the package body by this invention. In FIG. 7, the wrapping film 1
Since the packaging state, the non-adhesive portion 5, the notch portion 6 and the weakly adhesive portion 7 are the same as those in the first, second and third embodiments of the present invention described above, detailed description thereof will be omitted here.

In the fourth embodiment of the present invention, the notch 8 is further provided in the vicinity of the position where the edge of the lower lapping film intersects with the extension line of the notch 6. It is a thing.

First, similarly to the first embodiment of the present invention, the end portion of the non-adhesive portion 5 is squeezed with a finger or a nail, and the finger or the like is moved in the direction of arrow A in FIG. As a result, as shown in FIG. 8, the wrapping film 1 is torn from the cut portion 6 and the tear opening from the cut portion 6 is widened, a part of the weakly bonded portion 7 is peeled off, and the wrapping film 1 is opened wider. Become.

The tear opening formed by such tearing produces an action of tearing the wrapping film 1 so as to surround it by pulling and tearing the end 4a of the upper film as in the first embodiment of the present invention. The wrapping film 1 can be opened wide.

Further, in the fourth embodiment of the present invention, the notch 8 formed in the lower lapping film 1
By squeezing the end 4b of the lower lapping film 1 in the vicinity of and pulling it in the direction of the arrow B, the lapping film 1 is torn from the notch 8 as shown in FIG. 1 is greatly opened in the direction opposite to the direction in which 1 is opened, and thus the wrapping film 1 is further opened greatly,
The film 1 can be peeled off so that the package 10 is exposed almost completely.

Furthermore, since the cut portion 6 is formed in the vicinity of the surface of the packaged body 10 on which the side seal portion 13 is formed, the wrapping film left on the surface on which the side seal portion 13 is formed. 1 is the remaining wrapping film 1
It can be peeled off very easily by pulling in the direction of removing.

Incidentally, in the fourth embodiment of the present invention,
Although the notch 8 is provided in the lower wrapping film 1, in the second and third embodiments of the present invention, the edge of the lower wrapping film and the extension of the notch are also extended. A notch may be provided near the position where the line intersects.

Further, the notch and notch of the package according to the fourth embodiment of the present invention may be formed before packaging the packaged body 10, and after packaging the packaged body 10. Although it may be formed, it is desirable to be formed in advance before packaging in consideration of damage to the article to be packaged 10 due to a cutter or the like. In addition, when forming the notch and the notch in advance,
As shown in FIG. 10, by making a cut across the broken line portion of the wrapping film 1 cut at the broken line portion, the cut portion and the cutout portion can be formed at the same time.

Further, in each of the above-described embodiments, the shape of the notch or notch is provided so as to be substantially orthogonal to the edge of the body seal portion. However, as shown in FIG. 6 or the notch portion 8 may be provided so as to be oblique to the end edge of the body seal portion 4.

Further, in the above-described embodiment, the notch or notch is a linear notch or notch, but as shown in FIG. 12, for example, the notch 6 or notch 8 is V-shaped. The notches 6 and the notches 8 may be formed in a letter shape so that they can be easily pushed. The shapes of the cutouts and the cutouts can be applied to the above-described second, third or fourth embodiment of the present invention.

Further, in order to make the position of the non-adhesive portion or the tearing direction clear, for example, as shown in FIG. 13, a mark 20 such as an arrow may be attached to the wrapping film.

Furthermore, the non-adhesive portion may be colored so as to have a different color from the other portions of the wrapping film so that the position of the non-adhesive portion is clear.

In the above-described embodiment, the packaged body is an audio cassette. However, as shown in FIG. 14, for example, the packaged body of the present invention is formed on the wide surface of which the body seal portion 4 forms a rectangular parallelepiped. Of course, it can be applied to a video cassette. Further, in the above-described embodiment, the object to be packaged is a rectangular parallelepiped such as an audio cassette or a video cassette, but the present invention is not limited to this, and the package according to the present invention has a spherical shape, a rectangular parallelepiped shape, a circular cylinder, a cone shape. As long as it has a shape that can be wrapped with a wrapping film, it can be applied to any shape of the object to be wrapped.
