Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an overlap wrapping film used for covering, for example, a box containing a container such as cosmetics or food.
[0002]
[Prior art]
Generally, containers containing cosmetics, foods, medicines, and the like are individually stored in a box (outer box), and the boxes are grouped into one or a plurality of pieces and packaged with a film material. In this case, the film material is wound around the box, and both ends of the film material are overlapped and fixed to cover the box.
[0003]
In addition, the film material is provided with a cut line in the outer overlapping part that overlaps with each other, and when the film material is opened and the box body is taken out, a part of the outer overlapping part is pinched and pulled in the winding direction along the cut line. Thus, a part of the film material is cut into a band shape and opened.
[0004]
[Problems to be solved by the invention]
By the way, in the above-described prior art, a cut line is provided in the outer overlapping portion of the film material, and a part of the film material is pulled along the cut line to be opened. However, when the film material is pulled, it is first cut into a strip shape, but gradually becomes tapered and cuts during the opening. For this reason, the film material has to be pinched and pulled again from the middle of opening, and there is a problem that the opening operation requires time.
[0005]
Therefore, as another method for facilitating the opening operation, there is a method in which both ends of the film material are stopped by static electricity, or a fibrous strip is separately fixed to the film material so that it does not break during the opening. There is a way to do it. However, those using static electricity have a problem that the overlapped portion peels off during transportation. Moreover, the thing which fixed the strip | belt-shaped body separately has the problem of causing the raise of manufacturing cost.
[0006]
The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to allow a part of the film material to be cut into a strip shape without using another member, and to easily perform an opening operation. It is an object of the present invention to provide an overlap wrapping film that can be used.

Each box 2 is packaged with an overlap wrapping film 1 as a set of three pieces arranged in a row with the rear surface portion 2B and the front surface portion 2A facing each other.
[0017]
3 is a film material that wraps three box bodies 2, and the film material 3 is wound around each box body 2, and is fixed in a state in which both ends in the length direction are overlapped with each other. Each box 2 is wrapped by fixing each side by folding. Here, the film material 3 is formed in a transparent thin film shape using a resin material such as polyethylene terephthalate (PET). In the unfolded state shown in FIG. 3, the film material 3 is set so that the upper and lower dimensions are longer than the upper and lower dimensions of the box body 2 and the length dimension is wound around the three box bodies 2. The dimension is set such that both ends overlap each other to form a margin.
[0018]
That is, the upper part of the film material 3 when it is wound around the box 2 becomes the upper folding part 3A, and the lower part becomes the lower folding part 3B. One end side in the length direction of the film material 3 is an outer overlapping portion 3C that overlaps when the film material 3 is wound around each box 2, and the other end side is an inner overlapping portion 3D.
[0019]
Reference numerals 4 and 4 denote a pair of outer cut lines provided in the outer overlapping portion 3C of the film material 3. The outer cut lines 4 are spaced apart in the upper and lower directions perpendicular to the winding direction of the film material 3, that is, the opening direction.

And each perforation 5 guides so that a part of film material 3 may be cut off in the shape of a belt when pulling the outer overlapping portion 3C between the outer cut lines 4.
[0021]
6 is an inner cut line provided in the inner overlap portion 3D of the film material 3, and the inner cut line 6 is located at a position spaced from the edge of the inner overlap portion 3D, and the vertical cut portion 6A and the vertical cut portion 6A. A pair of horizontal cut portions 6B and 6B extending in the opening direction from both ends are formed as a U-shaped cut.
[0022]
Reference numerals 7 and 7 denote a pair of perforations provided in the inner overlapping portion 3D of the film material 3, and each perforation 7 extends in the opening direction following each lateral cut portion 6B of the inner cut line 6. And each perforation 7 guides so that a part of film material 3 may be cut off in strip shape, when inner side overlap part 3D is pulled by inner side cut line 6.
[0023]
Here, the width dimension (upper and lower dimensions) of the inner cut line 6 and the distance between the perforations 7 are slightly smaller than the distance between the outer cut line 4 and the perforations 5 described above. However, they are shifted in order to clearly describe both of them in the drawings, and preferably have the same width dimension (separation dimension).
[0024]
Reference numeral 8 denotes an opening mark as a mark provided on the inner overlapping portion 3D, and the opening mark 8 indicates the position of the inner cut line 6. The opening mark 8 is formed in a triangular shape so as to indicate the opening direction. Furthermore, since the film material 3 is transparent, the opening mark 8 can also indicate the position of the outer cut line 4 arranged so as to overlap the upper side of the inner cut line 6.
[0025]
The overlap wrapping film 1 thus configured is obtained by winding the film material 3 around each box 2 and overlapping the inner overlap portion 3D and the outer overlap portion 3C of the film material 3 (overlap). In the state, both are fixed using fixing means such as heat welding and adhesion. The welding part at this time is a part located outside the inner cut line 6 (vertical cut part 6A, horizontal cut parts 6B, 6B) as shown by dotted hatching in FIG. Furthermore, the upper folding part 3A and the lower folding part 3B of the film material 3 can be appropriately folded and fixed by fixing means so as not to open, so that the respective box bodies 2 can be covered.
