Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a package wrapped with a wrapping film, and more particularly, it has a form in which the wrapping film is closely attached to the packaged object such that the wrapping film sticks to the packaged object, for example, a magnetic tape cassette housed in a case. The present invention relates to a package in which one or more packages are simultaneously packaged.

[0002]

[Prior art]

 Among the products lined up at the stores of various recent retail stores, for products with a constant shape, such as magnetic tape cassettes, which are relatively small, they are dust-proof or moisture-proof, and aesthetics should be considered. The outer surface is then wrapped with a transparent or translucent cellophane, polyethylene, polypropylene, polyvinyl chloride, or a wrapping film such as a polyvinylidene chloride coated film. 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, an object to be packaged (product) wrapped with this type of wrapping film is naturally operated to remove the wrapping film when taking it out. In this case, for example, as shown in FIG. 19, 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 torn by appropriately tearing the wrapping film 1 by pulling the end 2a exposed on the surface thereof. A notch 3 along the tear tape is provided in the vicinity of the exposed end 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, and the wrapping film 1 is cut. The film 1 can be peeled off from the product.

[0005]

[Problems to be solved by the device]

 Such a wrapping film is generally wrapped in a so-called shrink wrapping method. This shrink wrapping is designed to wrap the product when the wrapping film is properly stretched when it is attached to the packaged product (product), or when it is heated to an appropriate temperature depending on the material of the film. Therefore, the shrinking force of the wrapping film causes the film to be packaged in good contact with the product in good appearance. The fact that the wrapping film is in close contact with the product in this way causes difficulty in peeling when the film is opened.Therefore, in the past, measures such as the provision of a tear tape as described above were made, and this tear tape is very effective. It was a step.

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

[0007] Furthermore, among the portions remaining after tearing the wrapping film with the tear tape, as shown in, for example, FIG. 19, the small area B can be easily removed depending on the position where the tear tape is arranged. However, the large area B remains after the tear tape is removed, and there is a problem that it takes a lot of time to peel off the remaining portion.

[0008] In view of the above circumstances, the present invention has an object to provide a package which does not require a special device or member and in which the wrapping film is largely torn at the time of opening to easily take out an object to be packaged. To do.

[0009]

[Means for Solving the Problems]

 A first wrapping body according to the present invention is a wrapping body in which an outer surface of an article to be packaged is covered with a wrapping film, and a body seal portion is provided by bonding both ends of the wrapping film to each other. A first notch formed substantially parallel to the edge of the lower film at or slightly off the edge of the body sealing portion of the upper wrapping film in FIG. An end portion of the lower film, and at least one second cut portion formed so as to cross the trunk seal portion at a right angle or obliquely with respect to the first cut portion. It is a feature.

Here, the term “welding” includes not only adhesion by an adhesive but also so-called welding in which heat is applied.

Further, in the first package according to the present invention, the second cut portion is formed so as to be substantially orthogonal to the first cut portion in the vicinity of the end portion of the first cut portion. Alternatively, a configuration may be adopted in which two second cutouts are formed at positions separated from each other with the first cutout sandwiched therebetween.

Further, according to the second package of the present invention, the outer surface of the packaged object is covered with the wrapping film, both ends of the wrapping film are overlapped, and the lower side of the overlapped wrapping film is In a package provided with a body seal portion having both ends bonded to each other at a position distant from the end edge of the film, the edge of the body seal portion of the wrapping film, which is the upper side of the body seal portion, and the lower side. A first notch formed substantially parallel to the edge of the lower film, at a position between the first film and the edge of the lower film, and the first notch at the end of the lower film. And at least one second cut portion formed so as to cross the body seal portion at a right angle or obliquely with respect to the cut portion.

Also, in the second packaging body according to the present invention, as in the first packaging body according to the present invention, the second notch is provided near the end of the first notch. A configuration may be adopted in which the first cut portion is formed so as to be substantially orthogonal to the first cut portion, or two second cut portions are formed at positions separated from each other with the first cut portion sandwiched therebetween. it can.

[0014]

[Action]

 Since the package according to the present invention is provided with the first notch and the second notch as described above, when the first notch is pulled, the wrapping films are superposed in double. Along the high-strength body seal portion, the body seal portion or the film along the body seal portion is torn at a single weak portion, and the film is torn so as to be roughly divided into two portions from the body seal portion. Then, when the tear region of the body seal portion is applied to the second cut portion, the direction of tearing the film spreads in a direction intersecting the direction along the body seal portion. As a result, the wrapping film can be opened wider, and the film can be peeled off very easily so that the article to be packaged is almost completely exposed.

[0015]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are views showing a first embodiment of a packaging body according to the present invention in which a video cassette is used as a packaging body.

As shown in FIG. 1 and FIG. 2, the wrapping film 1 has a rectangular parallelepiped shape of a rectangular parallelepiped of a packaged object 10 (in a state where it is stored in a storage case) whose both ends are video cassettes. They are superposed and heat-welded to form a body seal portion 4 (this body seal portion is shown by hatching below). 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 13, which are overlapping portions of both ends of the wrapping film 1, are welded by wrapping the article to be packaged 10 and then heating it appropriately.

Further, a first notch portion 6 formed substantially parallel to the body seal portion 4 is located at a position slightly near the end of the body seal portion 4 in the longitudinal direction and slightly away from the edge of the body seal portion 4. Then, a second cut portion 7 is provided across the body seal portion 4 so as to be orthogonal to the first cut portion 6 at the end of the film below the body seal portion 4. When the end 4a of the first cut portion 6 is pulled in the direction of the arrow X as shown in FIG. 2, the first cut portion 6 is connected to the second cut portion 7 and the lapping film 1 is doubled. Along the welded high-strength body seal portion 4, the portion of the film along the single weak imaginary line 8 is torn, and as shown in FIG. 3, the film 1 is roughly divided into two portions from the body seal portion 4 to both sides. To tear. At the same time, the tear from the second cut portion 7 causes an action of opening the wrapping film 1 along an imaginary line 9 that is substantially orthogonal to the body seal portion 4.

On the other hand, the body seal portion 4 is formed so as to extend substantially half around the longitudinal center of the packaged object 10 and reaches the side seal portion 13. Therefore, when the end 4a of the first cut portion 6 is pulled at the time of opening, the film 1 tears along the high-strength body seal portion 4 where the lapping film 1 is doubly welded, and the body seal portion is broken. From 4 will be divided into two sides. Further, when the tear region of the body seal portion 4 is applied to the side seal portion 13, the tearing direction of the side seal portion 13 including the folded portion of the wrapping film 1 is a lateral direction intersecting the tear direction of the body seal portion 4. The action that causes the spread in the direction occurs.

The tear opening formed by such tearing, together with the tear opening formed by the second notch 7, pulls the end 4a and tears the lapping film 1 by a single operation. It is possible to cause the opening action of the wrapping film 1 and the wrapping film 1 is opened more greatly. Therefore, the wrapping film 1 can be peeled off so as to completely expose one corner portion of the package 10, and the side opposite to the tearing direction (first and second in FIGS. 1 and 2). As for the wrapping film 1 (above the second cut portions 6 and 7), the wrapping film 1 is continuous on the side opposite to the side to be torn, so the remaining wrapping film 1 is removed. By pulling it on, it can be peeled off very easily by continuous operation.

Here, in the conventional case, of the wrapping film bisected by the tear tape, the part left on the side opposite to the tearing direction was relatively difficult to remove from the packaged object. In addition to the extremely effective peeling operation, it is not necessary to provide the tear tape itself, and the packaging is extremely advantageous in terms of cost.

It is necessary to form the second cut portion 7 on the packaged object 10 before packaging, but the first cut portion 6 should be packaged with the packaged object 10. It may be formed from, and considering damage to the packaged object 10 by a cutter or the like, it is desirable to form it before packaging.

Next, a second embodiment of the present invention will be described. 4 and 5 are views showing a second embodiment of the packaging body according to the present invention. 4 and 5, the packaging state of the wrapping film 1 is the same as that of the first embodiment of the present invention described above, and thus detailed description thereof will be omitted.

As shown in FIG. 4, at the position slightly deviated from the edge of the body seal portion 4 at the substantially central portion in the longitudinal direction of the body seal portion 4, a first portion formed substantially parallel to the body seal portion 4 is formed. The cut portion 6 and the first seal portion 4 are separated from the first cut portion 6 at the end of the film which is the lower side of the seal portion 4 so as to be orthogonal to the first cut portion 6. Two second notches 7a and 7b are provided across the portion 4.

When the end portion 4a of the first cut portion 6 is pulled in the direction of the arrow X as shown in FIG. 5, the wrapping film 1 is double welded along the strong body seal portion 4 and the film 1 But the single weak part is torn. When the film 1 is torn to the second cut portions 7a and 7b, the film 1 is torn along the virtual lines 8a and 8b which are substantially orthogonal to the body seal portion 4 by the second cut portions 7a and 7b. As a result, the film 1 is greatly opened so as to completely expose the body portion of the packaged object 10, and further, the film 1 goes around the body portion of the packaged object 10 and is peeled off to the position of the body seal portion 4 and left at the end. The film 1 can be peeled off very easily by pulling outwardly the open portions (outer portions of the second notches 7a and 7b in the figure).

Next, a third embodiment of the present invention will be described. 6 and 7 are views showing an embodiment of the present invention in which an audio cassette is used as a package. As shown in FIG. 6 and FIG. 7, the wrapping film 1 is superposed on the side of the narrow side of the audio cassette 11 (in a state where it is stored in the storage case) as a packaged object, and is heat-welded. The body seal portion 4 is formed. 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. Further, a first notch portion 6 formed substantially parallel to the body seal portion 4 is provided at a position slightly near the end of the body seal portion 4 in the longitudinal direction and slightly away from the edge of the body seal portion 4, A second cut portion 7 is provided across the body seal portion 4 so as to be orthogonal to the first cut portion 6 at the end of the film below the body seal portion 4.

Also in this case, the tear tape is not provided, and the body seal portion 4 is torn by pulling the end portion 4a of the first cut portion 6 in the direction of the arrow X as shown in FIG. The wrapping film 1 is torn along its imaginary line 8 along its entire length, similarly to the first embodiment of the present invention described above. Along with this, the tear from the second cut portion 7 opens along the imaginary line 9 substantially orthogonal to the body seal portion 4 to cause the operation of opening the wrapping film 1, whereby the wrapping film 1 is formed. Can be easily peeled off.

Further, in the case where the audio cassette is used as the object to be packaged as in the fourth embodiment of the present invention shown in FIGS. 8 and 9, the length of the body seal portion 4 is the same as in the second embodiment of the present invention. A first notch 6 formed substantially parallel to the body seal 4 at a position slightly deviated from the edge of the body seal 4 at the substantially central portion in the direction, and from the first notch 6 At the distant position, at the end of the film which is the lower side of the body seal portion 4, two second cut portions 7a, which cross the body seal portion 4 at right angles to the first cut portion 6, 7b may be provided.

Also in this case, when the end portion 4a of the first cut portion 6 is pulled in the direction of the arrow X as shown in FIG. 9, the lapping film 1 is doubly welded to the body seal portion 4 having a high strength. Then, the weak portion where the wrapping film 1 is a single layer is torn. When the wrapping film 1 is torn to the second cuts 7a and 7b, the film 1 is torn along the virtual lines 8a and 8b which are substantially orthogonal to the body seal 4 by the second cuts 7a and 7b. . As a result, the film 1 is largely opened so that the body portion of the packaged body 10 is completely exposed, and then the film 1 goes around the body portion of the packaged body 10 and is peeled off to the position of the body seal portion 4 and left at the end. The film 1 can be stripped off very easily by pulling outwardly the open portion (outer portions of the second cut portions 7a and 7b in the figure).

Further, in the above-described first to fourth embodiments of the present invention, the position of the first cut portion 6 may be changed depending on how the body seal portion 4 is welded. For example, as in the fifth embodiment of the present invention shown in FIG. 10, the wrapping film 1 is laminated at both ends thereof at approximately the center of the wide surface forming the rectangular parallelepiped of the object to be packaged 10 and is the lower film. When the body seal 4 is formed by heat welding at a position away from the edge of the body, the first position should be placed between the edge of the lower film and the edge of the body seal 4. One cutout 6 may be provided.

In the case of the fifth embodiment of the present invention shown in FIG. 10, when the first notch 6 is pulled in the same manner as in the first embodiment of the present invention, the film 1 is torn along the body seal portion 4. At the same time, the tear opening from the second notch portion 7 tears in a direction substantially orthogonal to the body seal portion 4, whereby the wrapping film 1 can be peeled off very easily as in the first embodiment of the present invention. . Further, in this case, it is more preferable that dust, dust and the like will not enter the film 1 through the first cut portion 6.

Further, as in the sixth embodiment of the present invention shown in FIG. 11, in the fifth embodiment of the present invention, two second notches 7a and 7b are provided as in the second embodiment. In case of providing the wrapping film, the wrapping film can be peeled off as in the second embodiment of the present invention.

In the first to fourth embodiments of the present invention, the first cut portion is formed at a position slightly separated from the edge of the body seal portion 4, but the body seal is It may be formed on the edge of the portion 4.

In order to make the position of the first cut portion clear, for example, as shown in FIG. 12, a mark 20 such as an arrow indicating the position of the first cut portion is attached to the wrapping film. You may

Further, in the above-described fifth and sixth embodiments of the present invention, the film which is the lower side of the body seal portion 4 as shown in FIG. 13 so that the position of the first cut portion is clear. The portion of No. 1 which is not welded may be colored differently from the other portions of the film 1.

Further, in the above-mentioned embodiment, the second cut portion is provided so as to be substantially orthogonal to the first cut portion, but as shown in FIG. 14, for example, the second cut portion is provided. 7 may be provided so as to be oblique to the first cut portion 6.

Further, in the above-described embodiment, the first cut portion is a linear cut portion, but as shown in FIG. 15, for example, the first cut portion 6 has a second cut portion at the end thereof. It is also possible to provide cutouts 6a and 6b that are substantially in direct contact with the first cutout 6 to facilitate the gripping of the first cutout. Further, as shown in FIG. 16, the first notch may be semi-circular, or as shown in FIG. 17, the first notch may be V-shaped, and further, as shown in FIG. The notch may have a wavy shape so that the first notch can be easily pinched. The shapes of the first cutouts can be applied to the fifth and sixth embodiments of the present invention described above.

[0039]

[Effect of device]

 As described in detail above, the package according to the present invention is provided with the notch for opening the package in the vicinity of the body seal portion of the package without providing the tear tape, so that the body seal portion 4 wraps when the package is opened. The film can be greatly torn. Therefore, it is no longer possible to divide the wrapping film into separate parts in the state where it is attached to the object to be packaged like opening with conventional tear tape, and remove the remaining packaging film like the conventional tear tape type. There is no need. In addition, it is possible to obtain various effects such that the processing for attaching the tear tape can be omitted in the processing step and the tear tape is not necessary, and the material cost can be reduced.
