BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 shown in FIG. 1 denotes a heat-shrinkable film 1 that is mounted in a close contact state by heat-shrinking a tubular container 5 as a packaged object. The heat-shrinkable film 1 is polymerized at both ends. It is formed in a tubular shape. Further, the heat-shrinkable film 1 may be provided with a design, characters, etc. by printing or the like.

Reference numeral 2 is provided on the inner surface side of the heat-shrinkable film 1, and one end 2a is provided so as to project outward from the end of the overlapping portion of the heat-shrinkable film 1, and the heat-shrinkable film 1 is provided. 1 is an opening tape formed from a film having the same heat shrinkability as 1. As shown in FIG. 2, the unsealing tape 2 comprises a heat-sensitive adhesive layer 3 provided on the inner surface of the heat-shrinkable film 1 and an adhesive layer 4 provided on the unsealing tape 2 side.
It is adhered to the heat-shrinkable film 1 via.

The heat-sensitive adhesive layer 3 is provided with the unsealing tape 2 so that the extending portions 3a extending from both sides of the unsealing tape 2 are formed.
The heat-shrinkable film 1 is applied to the container 5 with a width slightly wider than that of the heat-shrinkable film 1 activated by a temperature of about 80 ° C.
It is formed so that it can be attached and fixed to the surface.

Further, the adhesive layer 4 provided on the side of the unsealing tape 2 is preferably formed by applying a heat-sensitive adhesive which is activated at a temperature of about 60 ° C. and has adhesiveness. Further, the heat-shrinkable film 1 hardly heat-shrinks at about 60 ° C. at which the adhesive layer 4 is activated.

The container 5 to which the packaging material 7 having the above-mentioned structure is mounted is composed of a container body 5a and a lid 5b capped on the container body 5a, and the unsealing tape 2 is a packaging material. When the container 7 is attached to the container 5, the container body 5a and the lid 5b
The heat-shrinkable film 1 is bonded in the circumferential direction so as to be located on the outer surface of the joint portion 5c.

Next, the case of forming the package 10 as described above will be described.

First, the heat-sensitive adhesive layer 3 is formed by applying a heat-sensitive adhesive that is activated at about 80 ° C. to the inner surface of the rectangular heat-shrinkable film 1. On the other hand, the adhesive layer 4 is formed by applying an adhesive agent activated at about 60 ° C. to one surface side of the unsealing tape 2.

Then, the adhesive layer 4 of the unsealing tape 2 is separated by 6
It is heated to about 0 ° C. to activate it, and is laminated and bonded to the heat-sensitive adhesive layer 3 of the heat-shrinkable film 1. At this time, the heat-sensitive adhesive layer 3 is slightly extended from both ends of the unsealing tape 2, and the one end 2a of the unsealing tape 2 projects from the one end of the heat-shrinkable film 1. Adhere to the heat-shrinkable film 1.

Further, the adhesive layer 4 of the unsealing tape 2 is 60 °
The opening tape 2 is activated before and after C and is adhered to the heat-shrinkable film 1 by the adhesive layer 4, but since the heat-shrinkable film 1 hardly heat-shrinks at the temperature, the heat-shrinkable film 1 is wrinkled. Etc. will not occur. Further, since the heat-sensitive adhesive layer 3 is a heat-sensitive adhesive that is activated at 80 ° C. or higher, no adhesiveness is generated at this time.

Next, the heat-shrinkable film 1 to which the unsealing tape 2 is adhered is formed into a tubular shape so that the unsealing tape 2 is on the inner surface side, and one end 2a of the unsealing tape 2 is projected to the other end. Both ends of the heat-shrinkable film 1 are adhered with an adhesive or the like so that one end 2a of the unsealing tape 2 is projected onto the outer surface by being polymerized on the end to form a packaging material 7.

Further, the packaging material 7 is fitted into the tubular container 5, and then the heat-shrinkable film 1 is heat-shrinked,
The container 10 is tightly attached to the container 5 to form the package 10.

The heat at the time of the heat shrinkage activates the heat-sensitive adhesive layer 3 to generate adhesive property, so that the unsealing tape 2
By the extending portions 3a of the heat-sensitive adhesive layer 3 extending from both sides, the portions of the heat-shrinkable film 1 along both sides of the opening tape 2 are adhered to the surface of the container 5 and fixed to the container 5 side. Further, the unsealing tape 2 previously adhered by the adhesive layer 4 can be surely adhered by re-adhering it with the heat-sensitive adhesive layer 3 having adhesiveness. Furthermore, by pressing with a heat roller or the like from the surface side of the heat-shrinkable film 1 having the heat-sensitive adhesive layer 3, the container 5 becomes stronger.
It can also be glued to the side.

The wrapping material 7 is attached to the container 5 in this way, but the opening tape 2 is preliminarily attached at the bonding position so that the opening tape 2 becomes the outer surface of the joint portion 5c between the container body 5a and the lid 5b after heat shrinking. Decide.

Next, the case of opening the package 10 thus formed will be described. First, holding the one end 2a of the unsealing tape 2 projected on the outer surface of the heat-shrinkable film 1, the container 5 is pulled in the circumferential direction to guide and tear the heat-shrinkable film 1 (see FIG. 3).

The heat-shrinkable film 1 is torn in the circumferential direction of the container due to the guidance of the opening tape 2. However, as described above, the heat-shrinkable film 1 on both sides of the opening tape 2 has the heat-sensitive adhesive layer 3. Since it is adhered and fixed to the surface of the container 5 by the extending portion 3a of the container 5, when the opening tape 2 is pulled as shown in FIG. The heat-shrinkable film 1 is broken, so that the heat-shrinkable film 1 is surely opened along the opening tape 2.

The opening tape 2 is composed of a container body 5a and a lid.
Since it is provided on the outer surface of the joint part 5c of the 5b, the heat-shrinkable film 1 is separated and the heat-shrinkable film 1 is attached to the lid body 5b side and the container body 5a side after being opened at that position. The lid 5b can be removed from the container body 5a.
In particular, when the heat-shrinkable film 1 is used for printing or the like by printing or the like, it is convenient if the heat-shrinkable film 1 can be used with the heat-shrinkable film 1 attached to the container 5. is there.

Further, the unsealing tape 2 is adhered to the heat-shrinkable film 1 by the adhesive layer 4 formed on one surface side of the unsealing tape 2, and the adhesive layer 4 heat-shrinks the heat-shrinkable film 1. When the adhesive is adhesive at a temperature lower than the temperature, the unsealing tape 2 is preliminarily adhered to the predetermined position of the heat-shrinkable film 1 by the adhesive layer 4 without heat-shrinking the heat-shrinkable film 1. It is possible,
The opening tape 2 can be easily adhered to a correct position.

In the above-mentioned embodiment, the adhesive layer 4 is formed by applying a heat-sensitive adhesive having adhesiveness at a temperature of about 60 ° C. However, the adhesive layer 4 is formed by applying the heat-sensitive adhesive. Does not have to be a condition, and may be a pressure-sensitive adhesive. The point is that the adhesive layer 4 is formed from an adhesive that produces adhesiveness at a temperature lower than the temperature at which the heat-shrinkable film 1 heat-shrinks. Good.

Further, it is not a condition that the mounted body on which the heat-shrinkable film 1 is mounted is also the cylindrical container as in the above embodiment.
