[Industrial applications]

 The present invention relates to a product for tightly packaging an entire packaged object with a film or the like, and more particularly to a package body having improved ease of opening.

[0002]

[Prior Art]

 In general, box-shaped articles such as tape cassettes are packaged and sold with a packaging film. Since the outer peripheral surface of this box-shaped article is flat, the packaging film is adhered to the outer peripheral surface and is packaged by heat-sealing or adhering the overlapping end surface with an adhesive. In, there is a problem that the packaging film is difficult to peel off. For this reason, conventionally, a cut tape has been joined to the inner surface side of the packaging film, and when packaging the product, the cut tape is sandwiched between the product and the packaging film, and the packaging film is peeled off during use. In this case, the cut tape is pulled, the packaging film is cut, and the film is torn from the cut edge and peeled off from the packaged item.

[0003]

[Problems to be solved by the device]

 However, the conventional package having such a structure has the following problems. First, the cut tape cut position is displayed on the overlap surface during printing, but due to errors in the cut tape attachment position, winding film winding errors, etc., the print position and the cut position are separated and visibility is improved. There is a problem that it decreases. In addition, it may not be possible to print the cut indication due to the design, in which case it may not be possible to instantly determine the cut position, and it may take time to open the cut. In addition, the cut tape cuts are generally small and difficult to pick, and even if they can be picked, the width of the cut tape is narrow, so it is easy to completely tear the packaging film when the heat seal strength is high. is not.

The present invention has been made in view of the above circumstances, and has an excellent visibility of the unsealing portion of the packaging film and allows the packaging film to be easily unsealed over the entire body. Is intended to provide.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the package of the present invention is provided with an unsealed part on a part of the end faces to be overlapped on the outside of both end faces of the packaging film to be overlapped and adhered, as shown in FIG. 1, for example. A notch is formed in the unsealed portion and a peeling label is attached to the surface side of the unsealed portion.

[0006]

[Action]

 Since the package of the present invention is configured as described above, it is used as described below. In the packaged state, a peeling label is attached to the upper surface of the unsealed portion to prevent the packaging film from peeling accidentally from the notched unsealed portion. With this peeling label, the cut position can be easily determined. To open the packaging film, one end of the peeling label is picked up and pulled, and the peeling label is torn from the cut portion and peeled off as a whole.

【Example】

 Hereinafter, a first embodiment in which the present invention is applied to an 8 mm video tape cassette will be described with reference to FIGS. 1 to 5. In FIG. 1, reference numeral 1 is a wrapping film, and the wrapping of the object to be packaged A is such that both end face portions 1a and 1b are overlapped and bonded (heat-sealed) on the rear face side, and both side faces are on both side ends. This is performed by folding and bonding (heat sealing) the edge surface portions 1c and 1d.

In this embodiment, an unsealed portion 2 is provided at a part of the end surface portion 1 a of the packaging film 1 which is superposed on the outer side of the both end surface portions, and cuts are made on both sides of the unsealed portion 2. 2a and 2b are formed to form a cut 2c between them, and as shown in FIG. 2, a peeling label 4 is attached so as to cover the entire surface of the unsealed portion 2.

The unsealed portion 2 is for weakening the seal strength in the vicinity of the cut 2c of the outer end surface portion 1a of the packaging film 1. In this embodiment, as shown in FIGS. The printing surface 3 is also formed on the inner surface side including the pair of notches 2a and 2b, and the welding of the packaging film 1 at this portion is prevented, so that the overlapping portion of the films is not sealed when heat sealing. Form. Further, as shown in FIG. 4, the unsealed portion 2 can be formed by retracting the heater for heat sealing only between the notches 2a and 2b when heat-sealing the outer end surface portion 1a of the film 1. is there.

As shown in FIG. 1, the peeling label 4 has a substantially elliptical shape in a plan view, and has a sufficient adhesive force obtained by applying glue to the back surface, that is, stronger than an adhesive force obtained by heat-sealing the film. It has an adhesive surface 4a that secures adhesive strength and a non-adhesive surface 4b that is a non-adhesive surface, and a crease 4c is applied to the boundary line between the adhesive surface 4a and the non-adhesive surface 4b. When the peeling label 4 is attached to the packaging film 1, the non-adhesive surface 4b is lifted from the packaging film 1 and is easily picked by the urging force 4c. The non-adhesive surface 4b formed on the peeling label 4 is formed as a surface on which no adhesive is applied, but the adhesive is applied to the entire back surface of the peeling label 4 and printed on the surface corresponding to the non-adhesive surface 4b. That is, the printed layer is formed on the glue surface to cover the glue surface. In the formation of the non-adhesive surface 4b of the peeling label 4, the latter forming method has good workability and is advantageous in cost.

Since this embodiment is configured as described above, it functions as described below in the packaged state and at the time of opening. The tape cassette, which is the article A, is wrapped with the packaging film 1 and the peeling label 4 is attached so as to cover the surface of the unsealed portion 2 at the adhesive surface 4a. This prevents the packaging film 1 from being inadvertently peeled from the unsealed portion 2 in the packaged state. Further, since the peeling label 4 is attached to the entire unsealed portion 2 which becomes the cut 2c, the cut position can be instantly judged.

At the time of opening, the non-adhesive surface 4b of the peeling label 4 is pinched with a fingertip and peeled off in the direction of arrow X in FIGS. 2 and 3. Since the peeling label 4 is strongly adhered to the packaging film 1 by the adhesive surface 4a, the packaging film 1 is split from the notches 2a and 2b of the unsealed portion 2 and the cut 2c is enlarged, as shown in FIG. As shown in Fig. 3, it is gradually torn off as a whole with a certain width.

In this opening operation, since the non-adhesive surface 4b of the peeling label 4 is in a state of being lifted from the packaging film 1, it is easy to pick it with a fingertip, and since the label can increase the area to be torn at once, The opening work can be done quickly.

Next, a second embodiment will be described based on FIG. 6 and a third embodiment will be described based on FIG. 7. The same components as those of the first embodiment will be designated by the same reference numerals. The explanation is simplified. In the second embodiment, a wedge-shaped cut 2c is formed at the upper end of the unsealed portion 2 of the first embodiment with the notches 2a and 2b facing each other and formed in an inclined shape. The label 4 is attached to the side. The shape of the cut 2c is a wedge shape in the present embodiment, but it is not limited to this and various shapes can be adopted, for example, a U shape may be used.

According to the present embodiment having such a configuration, the cut end 2c is torn and torn from the tip, and thus the operation and effect that the unsealing work becomes quick and reliable can be achieved.

In addition, in the third embodiment, instead of the wedge-shaped cut 2c of the second embodiment, a guide piece 5 is provided at the center of the upper end of the unsealed portion 2 and cuts are formed on both sides of the guide piece 5. 5a and 5b are formed, and a cut tape 6 is attached from the guide piece 5 to the inner surface of the unsealed portion 2 and the inner surface of the packaging film 1 on the extension line thereof. Then, the peeling label 4 is attached to the front surface side.

With the above configuration, in this embodiment, when the peeling label 4 is peeled off, the cut tape 6 is peeled off via the guide piece 5, and the packaging film 1 is broken together with the cut tape 6, so that the width It is not necessary to pinch the end of the thin cut tape, and the packaging film 1 can be peeled off more easily and surely than the above-mentioned two examples.

The present invention can be variously modified without departing from the spirit thereof. For example, if at least one cut 2a, 2b is provided, the above-described action and effect can be obtained, and the peelable label 4 can be provided. Needless to say, the shape may be a perfect circle or a quadrangle, and the non-adhesive surface 4b can be formed at any position on the peeling label 4.

[0019]

[Effect of the device]

 As described above, since the peeling label is attached to the cut portion of the opening portion in the packaging body of the present invention, the visibility of the opening portion is excellent, and it is not necessary to print and display the packaging film itself. Even if it is transparent, it is possible to display the cut edge. In addition, since the peeling label is not adhered to a part and the portion to be picked up with a fingertip or the like can be made large, and the peeling label has a wide width, the entire packaging film can be peeled easily and quickly.
