Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package packaged with a wrapping film, and more particularly, to a package in which a wrapping film is in close contact with a package to be packaged. The present invention relates to a package in which one or a plurality of packages to be packaged such as a tape cassette are simultaneously packaged.

[0002]

2. Description of the Related Art In recent products arranged in stores at various retail stores, for example, a product having a constant shape and a relatively small size, such as a magnetic tape cassette or the like, is dust-proof or moisture-proof. In addition, the outer surface is wrapped with a transparent or translucent cellophane, polyethylene, polypropylene, polyvinyl chloride, or a wrapping film such as a film coated with polyvinylidene chloride on these in consideration of aesthetics. The magnetic tape cassette or the like is shipped as a wrapped package, or an appropriate number of commodities are collectively wrapped and displayed at a store as one package for sale.

[0003] Conventionally, when an object to be packaged (product) wrapped with this kind of wrapping film is taken out, the operation of removing the wrapping film is naturally performed. In the case of (1), for example, as shown in FIG. 17, a tear tape 2 is generally provided, and a configuration for facilitating removal of the packaged object 10 is generally adopted.

[0004] That is, the tear tape 2 can tear the wrapping film 1 as needed by pulling the end 2a exposed on the surface thereof, and cut it. A cut 3 is provided along the tear tape near the exposed end 2a of the tear tape 2 to facilitate tearing. With such a configuration, the wrapping film 1 can be torn along the tear tape 2 from the end 2a. As a result, the wrapping film 1 is severely torn or divided into two parts. Can be stripped from the product.

[0005]

Such a wrapping film is often wrapped in a so-called shrink package. The shrink wrap is heated at an appropriate temperature after the wrapping film is stretched appropriately when the wrapping film is mounted on the packaged object (product), or after the product is wrapped by the film material, and then heated at an appropriate temperature. By the action of the shrinking force, the film is packaged with good appearance in close contact with the product. The fact that the wrapping film is in close contact with the product
Since it is difficult to peel the film when the film is opened, conventional measures such as providing a tear tape as described above have been used, 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 attaching device and an attaching process are required, but also the tear tape needs to be more durable in function than the wrapping film. Yes, the cost for the tear tape was high.

[0007] Further, among the portions remaining after tearing the wrapping film with the tear tape, as shown in FIG. 17, for example, depending on the position where the tear tape is arranged, a small area b can be easily removed. The part of the large area B remains after taking the tear tape,
There is a problem that it takes much time and effort to remove the remaining portion.

For this reason, a weak adhesive portion which is easy to peel is provided on a body seal portion where both ends of the wrapping film are overlapped and adhered, and a portion remaining after the wrapping film is torn with tear tape is removed from the weak adhesive portion. An invention has been proposed in which the wrapping film can be easily peeled off by peeling it off greatly (Japanese Utility Model Application Laid-Open No.
32066).

However, the invention proposed in Japanese Utility Model Laid-Open No. 3-32066 still requires the provision of a tear tape, and therefore requires an attachment device and an attachment step for providing the tear tape. The cost for 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.

[0010] On the other hand, a bonded portion where the wrapping films are bonded to each other and a non-bonded portion are provided on the body seal portion.
A packaging body has been proposed in which a plurality of linear perforations are provided in the wrapping film constituting the outside of the body seal portion so that the wrapping film can be peeled off without using a tear tape (Japanese Utility Model Application Laid-Open No. 4-44). 84166).
According to this package, when the film is lifted by placing a finger on the non-adhered portion of the body seal, the edge of the body seal is torn and the perforation near the part is cut off. Since the film is torn along, the film can be easily removed without using a tear tape.

By the way, in the package described in Japanese Utility Model Application Laid-Open No. 4-84166, the wrapping film is peeled off from the non-adhered portion, so that the area of the non-adhered portion needs to be increased in order to break the wrapping film greatly. There is. However, if the non-adhesion part is enlarged, the hermeticity of the package will not be maintained.

In view of the above circumstances, the present invention does not require any special device or member, and the wrapping film is greatly torn at the time of opening by a single operation, so that the packaged material inside can be easily taken out, and furthermore, its sealing property can be improved. It is an object of the present invention to provide a package that can also hold a package.

[0013]

A package according to the present invention comprises:
In a package having an outer surface of a packaged object covered with a wrapping film and having a body seal portion in which both ends of the wrapping film are overlapped and adhered to each other, an end of the wrapping film on the upper side of the body seal portion. The edge, the non-adhesive portion provided so as not to be bonded to the edge of the wrapping film on the lower side, and the edge of the wrapping film on the upper side at the end of the upper wrapping film. Perpendicular or skewed to
A cut portion formed in proximity to the non-adhesive portion through a part of the body seal portion, and the upper portion adjacent to a side of the non-adhesive portion opposite to a side where the cut portion is provided. And an end portion of the lower wrapping film, which extends a predetermined length along an edge of the wrapping film, and a weakly bonded portion where weak bonding is performed.

Here, the notch is formed “close to” the non-adhesive portion through the body seal portion because the cut portion does not come into contact with the non-adhesive portion, and the cut portion does not contact the non-adhesive portion. Slightly from the non-adhesive part through the part (preferably 2-3 m from the non-adhesive part)
m) It means that it is provided at a remote location.

[0015] In the package according to the present invention, the unsealed portion including the non-adhesive portion, the cut portion and the weakly-adhesive portion may have two unsealed portions.
Alternatively, they may be provided so as to face each other with the weak adhesive portions facing inward.

Here, "provided with the weakly bonded portions facing each other with the weakly bonded portions inside" means both the case where the two weakly bonded portions are provided with an interval between the weakly bonded portions and the case where the two weakly bonded portions are shared. Including cases.

Further, in the package according to the present invention, in the above-mentioned package, a notch is provided near an edge of the lower wrapping film near a position where the edge intersects with an extension of the notch. May be further provided.

In each of the above-mentioned packages, a mark may be added to the non-adhesive portion to clearly indicate that it is a non-adhesive portion, or the non-adhesive portion or the vicinity of the non-adhesive portion may be opened in an opening direction. May be added.

[0019]

In the package according to the present invention, the end of the above-mentioned non-adhesive portion is picked up by a finger, a nail, or the like, and the end is pulled in a direction substantially perpendicular to the body seal portion. While being torn, the weakly adhered portion of the body seal is peeled off, and spreads in a direction substantially orthogonal to the body seal. As a result, the wrapping film is opened more widely, and the film can be peeled off very easily so as to expose the package almost completely.

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 hermeticity of the package can be maintained.

Further, if two unsealing portions including the above-mentioned non-adhesive portion, cut portion and weak adhesive portion are provided facing each other with the weak adhesive portion inside, any of the non-adhesive portions can be provided. The wrapping film can be opened, which is more preferable.

Furthermore, if a notch is further provided near the position where the edge of the lower wrapping film intersects with the extension of the cut portion, the upper wrapping film can be removed. By tearing the lower wrapping film from the notch, the wrapping film can be further opened greatly, and the wrapping film can be more easily peeled off.

If a mark for clarifying the position of the non-adhesive portion, the peeling direction and the like is provided,
This is more preferable because the position where the wrapping film is peeled off becomes clear.

[0024]

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

FIG. 1 is a view showing a first embodiment of a package according to the present invention using an audio cassette as a package.

As shown in FIG. 1, wrapping film 1
Is a package 10 whose both ends are audio cassettes
It is superimposed substantially at the center of the narrow surface of the rectangular parallelepiped (in the state of being stored in the storage case) and is welded by heating to form a body seal portion 4 (hereinafter, the body seal portion is indicated by hatching. display). Both ends of the body seal portion 4 are welded together with the film bent on the other surface and are formed so as to reach the side seal portion 13.

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

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

This weak adhesive portion 7 is made of the wrapping film 1
Is printed from the back surface of the wrapping film 1 in halftone printing or stripe-like printing on a portion corresponding to the weakly bonded portion 7, and when the body seal portion 4 is bonded by applying heat, halftone printing or stripe printing is used. It is formed by preventing welding of the entire surface of the body seal portion 4. As described above, the weak bonding portion 7 is formed by mixing the bonding region where the wrapping films are bonded to each other and the non-bonding region where the wrapping films are not bonded. However, it is not always necessary to uniformly mix the bonding region and the non-bonding region. For example, as shown in FIG. 15, the scattered density of the bonding region (black spot portion) of the weak bonding portion 7 is changed, and further, as shown in FIG. The area near the edge 4A may be formed as a non-adhesive stripe, and the adhesive area and the non-adhesive area may be formed in the weak adhesive section 7 with uneven distribution. Further, the weak adhesive portion 7 can also be formed by printing a portion corresponding to the weak adhesive portion 7 of the wrapping film 1 with a weak blocking ink.

First, the end of the non-adhesive portion 5 is picked up by 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 from the film.

Next, as shown in FIG. 3, when the end 4a of the peeled upper film is pulled in the direction of arrow A, the tear opening from the cut 6 widens, and a part of the weak adhesive part 7 is peeled. The upper film is lifted from the lower film. Further, when the end 4a of the film is pulled upward in the direction of arrow A, the tear from the cut 6 further widens, and the weak adhesive portion 7 is further peeled off. Further, when the end 4a of the peeled upper film is pulled in the direction of arrow A, the wrapping film 1 is opened further as shown in FIG.

The tear opening formed by such tearing can produce an action of tearing around the wrapping film 1 by an operation of pulling and tearing the end 4a of the upper film, whereby the wrapping film 1 can be produced. Will be opened wider. Thus, the film 1 can be peeled off so that the packaged object 10 is almost completely exposed.

Further, since the cut 6 is formed near the surface of the packaged object 10 where the side seal 13 is formed, the wrapping film left on the surface where the side seal 13 is formed. 1 is the remaining wrapping film 1
By pulling it in the direction in which it is removed, it can be peeled off very easily.

Here, in the conventional case, of the wrapping film bisected by the tear tape, the portion left on the side opposite to the tearing direction is relatively difficult to remove from the package. Compared to this, not only can a very effective peeling operation be performed by a single operation, but also it is not necessary to provide a tear tape itself, and packaging can be made extremely advantageous in terms of cost.

Next, a second embodiment of the present invention will be described. FIG. 5 is a view showing a second embodiment of the package according to the present invention. In FIG. 5, wrapping film 1

A second unsealing portion composed of a portion 7 'is provided so as to face each other with the weakly bonded portions 7, 7' inside.

As described above, the first opening portion composed of the non-adhesive portion 5, the cut portion 6, and the weak adhesive portion 7, and the first opening portion composed of the non-adhesive portion 5 ', the cut portion 6', and the weak adhesive portion 7 '. By providing the opening portion 2, 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 more easily opened.

In the above-described second embodiment of the present invention, the first and second opening portions are separately provided. However, as in the third embodiment of the present invention shown in FIG. It is also possible to use the weak adhesive portions 7, 7 'of the opening portion as a common weak adhesive portion. By using the common weak bonding portions 7 and 7 'as described above, it is possible to save the trouble of peeling the bonding portion between the weak bonding portions 7 and 7' as compared with the second embodiment of the present invention. More preferred.

Next, a fourth embodiment of the present invention will be described. FIG. 7 is a view showing a fourth embodiment of the package according to the present invention. In FIG. 7, wrapping film 1 is used.
Since the packaging state, the non-adhesive portion 5, the cut portion 6, and the weak adhesive portion 7 are the same as those in the first, second, and third embodiments of the present invention described above, detailed description will be omitted here.

In the fourth embodiment of the present invention, a notch 8 is further provided near the position where the edge of the lower wrapping film intersects with the extension of the cut 6. Things.

As a result, as shown in FIG. 8, the wrapping film 1 is torn from the notch 6 and the tearing opening from the notch 6 is widened, and a part of the weak bonding portion 7 is peeled off, so that the wrapping film 1 is opened more widely. Become.

As in the first embodiment of the present invention, the tear opening formed by such tearing produces an action of tearing around the wrapping film 1 by pulling and tearing the end 4a of the upper film. This allows the wrapping film 1 to be widely opened.

Further, in the fourth embodiment of the present invention, the notch 8 formed in the lower wrapping film 1 is formed.
9, the end 4b of the lower wrapping film 1 is gripped and pulled in the direction of arrow B, whereby the wrapping film 1 is torn from the notch 8 as shown in FIG. The wrapping film 1 is opened farther in the direction opposite to the direction in which the wrapping film 1 is opened.
The film 1 can be peeled off so as to expose the package 10 almost completely.

Furthermore, since the cut 6 is formed near the surface of the packaged object 10 where the side seal 13 is formed, the wrapping film left on the surface where the side seal 13 is formed. 1 is the remaining wrapping film 1
By pulling it in the direction in which it is removed, it can be peeled off very easily.

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

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

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

Further, in the above-described embodiment, the notch or notch is a linear notch or notch. For example, as shown in FIG. The notch 6 and the notch 8 may be easily grasped as a character shape. The shapes of these cut portions and cutout portions can be applied to the above-described second, third, or fourth embodiment of the present invention.

Further, for example, as shown in FIG. 13, a mark 20 such as an arrow may be provided on the wrapping film so that the position of the non-adhesive portion or the tearing direction is clear.

Further, the non-adhesive portion may be colored so as to be different in color from other portions of the wrapping film so that the position of the non-adhesive portion becomes clear.

In the above-described embodiment, the packaged object is an audio cassette. However, as shown in FIG. 14, for example, as shown in FIG. 14, the packaged body of the present invention is formed such that the body seal portion 4 is formed on a wide surface forming a rectangular parallelepiped. Of course, it can be applied to video cassettes. In the above-described embodiment, the packaged object is a rectangular parallelepiped such as an audio cassette or a video cassette. However, the present invention is not limited to this, and the package according to the present invention may be spherical, rectangular parallelepiped, cylindrical, or conical.
