Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging structure in which a box-shaped object such as a tape cassette, a floppy disk or a video cassette is wrapped with an overlap film and the overlap film can be easily opened. It is about.

[0002]

2. Description of the Related Art Box-shaped objects to be wrapped, such as tape cassettes or cigarettes, which are wrapped with this type of overlapping film, are well known. In the overlap film of these items to be packaged, a cut tape for opening is provided at a substantially determined position, and the cut tape is provided so as to substantially surround the body of the item to be packaged. The end portion is slightly extended to the side of the packaged item and taken out.

The overlap film thus wrapped on the article to be packaged is then shrunk by shrinking treatment so as to be tightly attached to the article to be packaged as a whole so as to be in good shape and close contact. . Then, the overlap film is to be opened by picking the end of the cut tape that is extended to the side and cutting the overlap film by pulling it along the trunk so that it makes a full rotation. is there.

[0004]

In the unsealing of the overlap film with the cut tape of the conventional example, the extension of the cut tape serves as the unsealing point, and the position where the cut tape is wound is extremely limited. Since there is an unsealing point at one point, not only there is the problem that the position is difficult to find, but there is also the problem that the tip of the cut tape is difficult to pick.

Even if the cut tape goes around the body part to cut the overlap film, only a part of the overlap film can be removed, and most of the overlap film remains on the body part. . For example, in cigarettes, etc., it is convenient to minimize the influence of outside air because there is a residual film, but in tape cassettes etc., it is not possible to use it unless all overlapping films are removed. It is inconvenient for the overlapping film of 1) to remain.

Therefore, the remaining overlap film must be removed. However, in the case of a packaged object formed of a relatively hard material such as a tape cassette, the remaining overlap film is It is difficult to peel off the overlap film because it is in a tense state and it is in close contact with it.
Since the cut by the cut tape is relatively straight, it is difficult to put a finger in the cut and tear it, and when you want to use it quickly, the remaining overlap film can not be easily removed and it can not be used in time There is a problem called.

Further, when a cut tape is used, in order to make it easier to peel off the remaining overlap film, a part of the overlap film is cut or perforated, or a plurality of overlap films are provided. It has been proposed that a cut tape is used to expand the cut portion.

However, in the case where the cut or perforation is provided, not only is there an inconvenience of tearing during the shrinking process, but also the position of the cut or perforation is not clear, and the cut is hard to see visually. For that reason, it is rarely actually used, and it is extremely difficult to peel off the overlapping film which still remains.

Furthermore, when a plurality of cut tapes are used, an extra cut tape is required, and an economical problem that an extra device must be added in an automated packaging device. In addition to the above points, there is a problem that the workability is deteriorated in the packaging work of the article to be packaged because the step of attaching the cut tape from different directions is required.

Therefore, in the conventional overlap film, the workability of packaging is improved, the opening point at the time of opening is widened, no cut tape is used, and the overlapping film is not left at the time of opening. In particular, it has problems that must be solved.

[0011]

Means for Solving the Problems As a specific means for solving the above problems, the present invention provides an overlap film for wrapping an object to be packaged and superimposing end portions thereof for sealing, wherein a non-adhesive portion is provided at a part of the sealing portion. The present invention is to provide a packaging structure using an overlap film, which is characterized in that the sealing portion is alternately provided with an adhesive portion and a non-adhesive portion; Wrapping so that it is on a wide surface; opening mark is provided on the seal part; adhesive part and non-adhesive part are alternately provided so that the adhesive part comes to the corner of the packaged object And the adhesive is
This includes weak adhesion.

[0012]

In the packaging structure of the present invention, the workability of the packaging is improved by forming the non-adhesive portion for opening in a part of the seal portion without using the cut tape, and at the time of opening, The overlap film can be easily and entirely removed with one touch by hooking the non-adhesive portion with a thumb to break it.

[0013]

EXAMPLES Next, the present invention will be described in more detail with reference to the examples shown in the drawings. 1 is an overlap film, and the overlap film 1 is used to wrap a box-shaped object 2 to be packed.

The box-shaped object to be packed 2 is a tape cassette for recording and / or recording provided with a recording medium such as a magnetic tape, a floppy disk, a video cassette, a magnetic floppy, a card in a case, or a case. The various articles contained are all included if they have a box shape as a whole.

The overlap film 1 is formed of a commonly used transparent, translucent or opaque material, for example, a film having a heat shrinkability such as polypropylene (PP), and is used for the article 2 to be packaged. It is to seal and wrap in a tight state.

The seal portion when wrapping this type of packaged article 2 is generally called a side seal, and the packaged article 2 is
Often sealed on the side.

That is, when the object to be packaged 2 is, for example, a tape cassette, a structure in which one long side surface of a rectangle and two short side surfaces adjacent to the long side are sealed is a so-called side seal. The seal referred to as "bulging" here is a relatively wide flat surface that crosses the front (front) or back (bottom) side of the tape cassette in the length direction or the width direction. In addition to the configuration, the seal portions are also configured on the side surfaces of both short sides.

In the embodiment of the present invention, for example, a stretcher which seals the back surface side of the object to be packaged 2 which is a tape cassette along the length direction will be described.
The wrap is completed by forming the seal portion 3 of the trunk and the seal portion 4 of the side seal on the side surface of the short side.

The seal portion 3 is composed of an adhesive portion 5 and a non-adhesive portion 6, and a plurality of the adhesive portions 5 and the non-adhesive portion 6 are alternately provided with a predetermined length to substantially form a non-adhesive portion in a part of the seal portion 3. can do.

The width of the seal portion 3 in this case is approximately 5 to 8 mm.
The length of the adhesive portion 5 is about 7 to 15 mm, and the length of the non-adhesive portion 6 is about 10 to 2 that a finger is caught.
It may be about 0 mm.

As shown in FIG. 2, the overlap film 1 is provided with an adhesive portion 5 and a non-adhesive portion 6 on one end side constituting the seal portion 3, and the adhesive portion 5 is a weak adhesive portion. The non-adhesive portion 6 is provided with a display portion 7 such as an “opening opening” or an arrow by means of printing or the like so that the opening can be understood at a glance.

As a means of weakly adhering at the adhering portion 5,
For example, by applying a printing varnish, a halftone printing or the like to the position corresponding to the adhesive portion 5, the heat sealing property originally possessed by the film itself is partially lost.

Further, both end portions of the seal portion 3, that is, the end-side adhesive portions 5a located on the sides of both short sides of the object to be packaged 2 are formed to be slightly longer than the other adhesive portions 5, and the object to be packaged is formed. It is formed so as to be located at a corner portion from the bottom surface to the side surface of 2. In this way, by forming the adhesive portion so as to be positioned at the corner portion, the rolling phenomenon of the seal portion 3 after packaging is eliminated, and stable packaging can be expected.

The seal portion 4 serving as a side seal is sealed by a conventional heat sealing means. The same applies to the conventional example in that the whole is shrink-treated after packaging.

In the case of the packaging structure having the body-tight seal portion 3 as described above, since the cutting tape unlike the conventional example is not required, the packaging apparatus itself becomes inexpensive and the workability of the packaging is good. Therefore, the efficiency can be improved.

Then, as shown in FIG. 3, when the overlap film 1 is to be removed when the object to be packaged is used, looking at the "opening" display portion 7, for example,
When the thumb is pushed into the opening, the non-adhesive portion 6 is opened and the adhesive portion 5 in the vicinity of the non-adhesive portion is peeled off. The entire overlap film 1 can be removed all at once from the mouth.

In this case, the position where the overlapping film 1 tears varies, but once a tear is made, the overlapping film 1 continues from the tear.
Since the adhesive portion of the body-tight seal portion 3 is weakly adhered, the opening portion can be opened over a wide range and can be easily picked with fingers. Overlap film 1 by picking the film
Can be peeled off.

[0028]

As described above, the packaging structure using the overlap film according to the present invention has a structure in which the non-adhesive portion is left on a part of the seal portion so that the sealing tape is not used. Not only is it economically advantageous and not only simplifies the packaging work and improves the production efficiency, but it can be torn from the non-adhesive part when opening to easily remove the overlap film and remove it all at once. It has an excellent effect.

Further, since the adhesive portion and the non-adhesive portion are alternately provided on the seal portion, the seal portion is stabilized, and the seal portion is packaged so that it is on a relatively wide surface of the package. Thus, the peeling and tearing work of the seal portion is facilitated, and by providing the seal portion with the unsealing indication, various excellent effects can be obtained in that the unsealing operation can be quickly performed without any confusion.

Further, since the adhesive portion and the non-adhesive portion are alternately provided so that the adhesive portion comes to the corner of the packaged object,
Since the seal portion is more stable and the adhesive portion is weakly adhered, an excellent effect that peeling at the time of opening can be performed easily is achieved.
