BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for packaging an object to be packaged, and more particularly, to a magnetic tape cassette (a magnetic tape cassette which can be used only after the package is peeled off. The present invention relates to a package for packaging one or more cases containing audio tape cassettes and video tape cassettes).

[0002]

2. Description of the Related Art Products such as magnetic tape cassettes are made of cellophane, polyethylene, polypropylene, polyvinyl chloride, or polychlorinated or transparent, whose outer surface is transparent or translucent in consideration of aesthetics, and in consideration of aesthetic appearance. It is shipped as a package that is packaged with a wrapping film such as a vinylidene-coated film. Conventionally, a packaged product (product) packaged with this type of wrapping film is naturally peeled off and taken out. However, a tear tape is provided inside the wrapping film, It is common to employ a configuration that makes it easy to take out the package. That is, the tear tape can be appropriately torn by pulling one end thereof to cut the wrapping film. As a result, the greatly torn or two split wrapping films can be very easily stripped from the product.

[0003]

Such a wrapping film generally uses a wrapping method called shrink wrapping, which is disclosed, for example, in Japanese Utility Model Publication No. Sho 62-15157. According to the packaging form disclosed in this publication, as shown in FIG. 4, when the wrapping film is mounted on the packaged object (product), for example, the wrapping film 10 of the packaged object (a rectangular parallelepiped product such as a cassette case) is appropriately changed. In a stretched state,
Alternatively, the wrapping film 10 is wrapped in a state where the wrapping film is
The film 10 ideally adheres to the packaged object due to the shrinkage effect of the film, and is excellent in appearance and appearance. However, on the other hand, it has a drawback that it is difficult to peel off. Therefore, in order to solve this problem, the following measures have conventionally been taken.

[0004] That is, as a conventional measure, as shown in FIG. 4, the tear tape 20 is provided so as to intersect the welded portion 40 where the wrapping film 10 is superimposed and heat-sealed. A projecting portion 21 is formed so that the tear tape 20 can be easily picked in the intersection area. Then, in order to easily tear the wrapping film 10, the film near one side of the tear tape 20 is used.
A notch 50 is formed on the tape 10 along the longitudinal direction of the tape, and another notch 70 is formed on the tear tape along the notch 50. On the opposite side of the sandwich, the welding force reducing portion 60 by printing is used to facilitate the peeling of the welding portion 40.
Is formed.

[0005] Further, the apparatus disclosed in Japanese Utility Model Laid-Open Publication No. 3-32066 has a structure in which a welding force reducing portion (weak bonding portion) is formed over the entirety of the welding portion 40 with reference to FIG. .

The former is provided with cuts 50, 70 provided on and near the tear tape 20 and a welding force reducing portion 60, so that the tear tape 20 is not inadvertently torn. , And the wrapping tape 10
It is intended to increase the strippability. However, the projecting portion 21 has the cuts 50 on both sides thereof.
Although 70 is formed, the operation of extracting the protruding portion 21 has not been improved so much. The reason for this is that the projecting portion 21 is expected to start this partial tearing because one of the cuts 70 is formed on the tear tape 20 made of a material having high tear propagation resistance, that is, a material having relatively high rigidity. It is not intended to improve the tear tape picking operation, but since the protruding portion 21 is in close contact with the lower film and has high rigidity, it is actually picked with a finger. Is difficult. Furthermore, since the other cut 50 is formed on the wrapping film in which the welding portion 40 is in close contact, the tear tape 20 cannot be easily picked. That is, after the tear tape 20 is extracted,
Although tearing is likely to start from the cut 50 and the welding force reducing portion 60, it is difficult to pull out the tear tape.

On the other hand, in the latter case, since a welding force reducing portion is formed in a wide range in the welding portion 40, particularly,
The wrapping film 10 can be peeled off very easily without relying on the tearing off of the tear tape 20. However, conversely, the welding force reducing section
Depending on the degree of formation of the (weak adhesive layer), it is very difficult to make adjustments and conditions in manufacturing, such as the wrapping film peeling off before it reaches the hands of the user (during transportation or other handling at the store). It had some troublesome and still not enough shortcomings. An object of the present invention is to solve the above-mentioned drawbacks, and it is an object of the present invention to prevent the wrapping film from being accidentally peeled off in the middle of a distribution route, while keeping the package easily openable.

[0008]

SUMMARY OF THE INVENTION The object of the present invention is to cover the outer surface of an object to be packaged with a wrapping film and to weld at least the joints of both ends of the wrapping film by heat sealing. In a package having a tear tape provided on the inner side of the wrapping film so as to intersect with the joining portion, the joining portion faces the intersection of the tear tape and the joining portion at least on the opening start side and surrounds the intersection. A heat seal sparse outer part having no welding or weakened welding force is formed, and a pair of slits substantially along the tear tape are formed so as to separate both sides of the tear tape in the heat seal sparse outer part, The gap between the slits is formed to be larger than the width of the tear tape, and the heat sheet is larger than the gap between the slits. It is achieved by packaging, wherein a width of the alienation portion is set large.

[0009] In this package, at least one of the boundary lines along the tear tape at the boundary line forming the heat seal sparse outer part and a boundary line intersecting the tear tape are provided. The object of the present invention can also be achieved by a package characterized by being configured to form an acute angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 is an enlarged plan view of an essential part showing an embodiment according to the present invention.
FIG. 4 is a perspective view showing a state in which a long box-shaped case is wrapped with a wrapping film. As shown in FIG. 2, the package 1 according to the present embodiment is configured to wrap a packaged object 5 which is a box-shaped case. Then, the package 1 covers the outer surface of the packaged object 5 with a wrapping film 3 and welds a joining portion of both ends of the wrapping film 3 by heat sealing to form a heat seal region 4. The tear tape 2 is provided on the inner side of the wrapping film so as to cross the seal region 4.

As shown in the enlarged view of FIG. 1, the characteristic structure of this embodiment is that at the intersection between the tear tape 2 and the heat sealing region 4 which is a film joining portion (the hatched portion in the drawing) Is a normal heat seal portion), and a heat seal sparse outer portion 7 in which the joining portion is not welded or whose welding force is weakened is formed so as to face the opening start side and surround the intersection. Further, a pair of slits 6 are formed on both sides thereof so as to sandwich the tear tape 2 in the heat seal sparse outer part 7 and extend substantially in the longitudinal direction of the tear tape 2. Then, the interval H between the slits 6, 6 is determined by the width w of the tear tape 2.
Are formed to be large, and both slits 6, 6,
The width W of the heat seal rough outer portion 7 is larger than the interval of.

With such a structure, when the wrapping film 3 wrapping the packaged object (product) 5 is peeled off, the tape 2 is provided on both sides of the tear tape 2.
The slits 6 are formed at more distant positions, and the portion where the slits 6 are formed is the heat seal sparse outer part 7. Therefore, for example, the slit 6 is rubbed in the tape pulling direction at the belly portion of the fingertip. Thereby, the portion sandwiched between the slits 6 can be easily flipped up. Further, by further picking up the turned-up portion together with the tear tape 2, both tears are simultaneously performed at the positions of the slits 6 on both sides, so that there is no instability at the beginning of tearing, and therefore, it is easy to pick and tear easily. The operation can be performed lightly. In addition, the size (width) L of the heat seal sparse outer part 7 in the heat seal width direction is configured to be smaller than the heat seal width HS, and the heat seal portion is left at the intersection, so that the heat seal is not transferred. Inadvertent peeling of the intersection during handling or during handling can be prevented. In addition, the heat-sealing outer portion 7 may have a non-adhesive structure in which the heat seal is not adhered at all, or may have a structure in which the adhesive force is extremely reduced by means of, for example, applying an appropriate printing to an adhered portion.

The present invention is not limited to the above-described embodiment, but can be configured as shown in FIG. In the present embodiment, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and redundant description will be avoided. In FIG. 3, the shape of the heat-sealed sparse outer portion (non-adhesive portion) 7 of FIG. 1 described above is a trapezoid, and one of the upper and lower sides is formed at an acute angle θ 1 is different from that of FIG. 1 described above.

Further, in the configuration shown in FIG. 3, in addition to the effects of the configuration shown in FIG.
When picked up, the shape of the heat seal sparse outer 7 is
Since the wrapping film 3 is formed in a trapezoidal shape inclined so that one side is opened in a tearing direction, the wrapping film 3 is torn in the extending direction of the oblique side in the inclination direction (the direction indicated by a dotted arrow in the drawing). Regardless of the properties of the wrapping film, regardless of the characteristics of the wrapping film, as shown in the conventional type, when the tear tape is unevenly distributed on one side of the packaged object 5, the side opposite to the tear tape is greatly torn. It is possible to avoid a trouble that a part of the film cannot remain and remains on the packaged object 5. Further, the inclined side in the heat seal sparse outer part 7 shown in FIG. 3 is not necessarily limited to one side, and a configuration may be employed in which both sides of the tear tape 2 are inclined so as to open in the tearing direction. Further, a configuration may be employed in which the cutting direction of the slit 6 is inclined along the inclined side.

[0015]

As described above, according to the present invention, when the wrapping film wrapping the packaged object is peeled off, slits are formed on both sides of the tear tape at positions away from the tape, respectively. Since the portion where the slit is formed is a heat seal sparse portion, the portion sandwiched between the slits can be easily formed by rubbing the heat seal sparse portion with a fingertip in a tape pulling direction when opening. It can be flipped over and it is very easy to pick out the tear initiation part. In addition, by picking up the turned-up portion together with the tear tape, the tearing is performed at the slits 6 on both sides at the same time, so that there is no instability at the beginning of tearing, it is easy to pick, and it is easy to tear, and the operation is light. A package which can be provided can be provided.

According to the present invention, the size (width) of the heat seal in the heat seal width direction is smaller than the heat seal width, and the heat seal is formed at the intersection of the tear tape and the welded portion. Since the portion is left, it is possible to prevent the intersection from being accidentally peeled off during transportation or handling. Further, according to the present invention, when the tear tape is picked up, the shape of the heat seal is formed in a trapezoidal shape in which one side along the tearing direction is inclined so as to open in the tape tearing direction. Since the wrapping film tears in the direction of extension along the direction of its inclination, regardless of the characteristics of the wrapping film, the tearing of the tear tape in the longitudinal direction of the wrapping film can greatly tear the wrapping film. Can be
