Abstract

PURPOSE:To make it easy to break the seal in unwrapping a rectangular object wound in packing film on fox sides perimetrically, by making two incisions in the fringe of the opening formed by the packing film which projects from an unwrapped side, one incision on each side of the joint of the packing film at the fringe, to form an unsealing tab. CONSTITUTION:In packing an object 1 such as a tape cassette, an unsealing tab 5 is formed by making two incisions 4a, 4b in the fringe 2b of the opening formed by a sheet of packing film 2 wound on the object 1 on four sides perimetrically, one incision on each side of the joint 2a of the fringe 2b. When the fringe 2b projecting from the unwrapped side of the object 1 is tucked down on the end side of the object 1, the unsealing tab 5 is brought to be exposed and, when the fringe 2b tucked on the end side is heat-sealed, the unsealing tab 5 is left loose. To break the seal, the unsealing tab 5 is pulled; since the joint 2a is formed thicker than the rest of the film, the unsealing is orientated and the packing film 2 is torn off along the joint 2a from top to bottom and severed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for wrapping a tape cassette isotropic object to be wrapped with a wrapping film.

[0002]

2. Description of the Related Art A conventional packaging structure will be described with reference to FIGS. As shown in FIG. 6, in order to wrap the tape cassette 1 housed in the protective case with a packaging film made of a material such as cellophane, polypropylene, or polyethylene terephthalate, first, the one circumferential surfaces 1a to 1d of the tape cassette 1 are shown in FIG. As shown, it is wrapped with the packaging film 2, and the overlapping portion of the packaging film 2 is heat-sealed to form the joint 2a.
Next, the open ends 2b and 2c of the packaging film 2 extending from the unwrapped surfaces 1e and 1f of the tape cassette 1 are folded and heat-sealed by a known method as shown in FIG. In the conventional packaging structure, a well-known tear tape 3 for opening is wrapped around the inner surface of the packaging film 2. When the packaging film 2 is opened, one end of the tear tape 3 is pulled to tear the packaging film 2, and the packaging film 2 is divided into a part (smaller one) 20 and a remaining part (larger one) 21 as shown in FIG. After separation, the tape cassette 1 was taken out after this. The same packaging structure was adopted when packaging a rectangular object to be packaged, not limited to the tape cassette.

[0003]

However, since the tear tape 3 is required to be used in the above-mentioned packaging structure, there is a problem that the packaging cost increases. Further, when the packaging film 2 is opened, since the residual portion 21 is in close contact and is difficult to extract, a finger is inserted between the tape cassette 1 and the residual portion 21 to break it, but the tape cassette 1 has a width orthogonal to the longitudinal direction. Since W was small, it was difficult to insert a finger, and it took time to remove the residual portion 21. Therefore, it is very inconvenient because it may not be in time for an emergency when it is desired to record immediately.

DISCLOSURE OF THE INVENTION The present invention is to solve the above-mentioned problems, in which one peripheral surface of a rectangular object is wrapped with a wrapping film and the overlapping portions of the wrapping film are joined to join the joints. On the other hand, in the packaging structure of the packaged object in which the open ends of the packaging film extended from the unwrapped surface of the packaged object are folded and joined, respectively, two cuts sandwiching the joint portion are formed at the open ends. A packaging structure for the packaged article, characterized in that the opening section is provided by putting it in, and the opening section is exposed, and the opening section is in a non-bonded state.
Further, in such a packaging structure for a packaged object, the packaged object is a tape cassette, and the joint portion is formed along a longitudinal direction of the packaged object. To provide the packaging structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. 1 is a perspective view showing a first embodiment of a packaging structure according to the present invention, FIG. 2 is a view showing a process at the time of packaging, FIG. 3 is a view showing a state in which a packaging film is opened in the first embodiment, FIG. Is a perspective view showing a second embodiment of the packaging structure according to the present invention, and FIG.
It is a figure which shows the state which opens a packaging film in an Example.
The same components as those in the conventional example are designated by the same reference numerals.

In the packaging structure shown in FIG. 1, when the tape cassette (package to be packaged) 1 is packaged, as shown in FIG. 2, two notches 4a which sandwich the joint 2a between the open ends 2b of the packaging film 2, 4b is inserted and the opening 5 is provided between them. Then, when the opening end 2b is folded, the unsealed portion 5 is exposed as shown in the drawing, and when the opening end 2b is folded and heat-sealed, only the unsealed portion 5 is brought into a non-bonded state (a state not heat-sealed). That is, the opening end 2b is sealed except for the opening portion 5. In addition, such a cut 4
The a and 4b may be formed on at least one of the open ends 2b and 2c of the packaging film 2.

The opening of the packaging film 2 is performed by pulling the opening portion 5. In the packaging film 2, the joint portion 2a is thicker than the other portions, so that the directionality is created at the time of opening, and the joint portion 2a can be peeled from the upper end to the lower end to tear the packaging film 2 as shown in FIG. In addition, if the directionality of the packaging film 2 itself and the forming direction of the joint portion 2a are the same, it becomes easier to tear.

In this packaging structure, since the packaging film 2 can be opened without using a tear tape, the packaging cost can be suppressed more than the conventional example. Further, since the joining portion 2a is provided along the longitudinal direction of the tape cassette 1, it becomes easy to put a finger between the tape cassette 1 and the packaging film 2 at the portion along the joining portion 2a, and the remaining packaging film is formed. Can be easily defeated, and even if you want to record immediately, you can easily deal with it.

The second embodiment shown in FIG. 4 is different from the first embodiment in that the joining portion 2a of the packaging film 2 is formed not on the largest surface 1a of the tape cassette 1 but on the next largest surface 1b. Is. Even in this case, by pulling the unsealing portion 5 provided on the surface 1e side of the tape cassette 1, the wrapping film 2 can be unsealed as shown in FIG.

In the present embodiment, the tape cassette 1 is used as the object to be packaged, but the scope of application of the present invention is not limited to the tape cassette, and any rectangular object can be applied. Needless to say.

[0011]

From the above description, the following effects can be expected in the packaging structure for a packaged article according to the present invention.

In the packaging structure according to the first aspect, since the packaging film can be opened without using the tear tape, the packaging cost can be suppressed more than the conventional example.

Further, in the packaging structure according to the second aspect, it is easy to put a finger between the tape cassette, which is the object to be packaged, and the packaging film at the portion along the joint, so that the remaining packaging film is easily broken. Therefore, there is a new effect that even if it is desired to immediately record the image, it can be easily dealt with.
