Figure 1 shows examples of conventional heat sealing bodies.

1A, a central portion of a thermal suture body 20 having no opening tabs is constructed such that a central portion of the thermal suture body 20 can be opened by breaking a suture body by using a finger or other mechanism do. The heat sealing material having such a structure is a structure that can be opened only if it is broken by a forced method because there is no opening tab, but it is not easy to break and even if diarrhea breakage is irregularly broken or torn, it is not good in appearance, . .

On the other hand, in the case of the container sealing body shown in FIG. 1 (b), there is a release tab, which is peeled off by opening the release tab and is opened. However, not only the entire container inlet is opened but also tamper evident function, There was a possibility of doubt about reliability and also there was a problem about stability of contents protection which is a disadvantage of peelable seal. In addition, when used as a container for pharmaceutical use, when a consumer pulls out a tablet, the contents are poured into the hands of a consumer at the same time and contaminated by the fungus on the hand of the contents over the usage amount. The entrance of the container facilitates the inflow of moisture or oxygen, and the contents are easily hardened or altered.

In order to open the one partial opening tabs 230 and 230 partially after the partial opening is completed, one side of the opening induction cutout strips 220 and 320 is opened at the left and right sides, .

In addition, an annular heat-sealing suture 210, 310 (which is separated from the open-mouth induction cut-off strips 220, 320 by the open-end induction cutting lines 231, 331 and which is in close contact with the lip of the container outside the open- ); / RTI >

The outer openings of the open induction cut-off strips 220 and 320, the direction of the container inlet of the partially opened tab, and the thermal adhesive sealing strips 210 and 310 are thermally bonded to the lower layer.

FIG. 5 is a view illustrating the structure of the lower layer 500. In order to facilitate the opening of the aluminum foil layer 520 and the heat-sealing resin layer 510 of the lower layer 500, An open cut induction cutting line is formed in the heat seal resin layer of the lower layer immediately under the open-cut induction cut lines 231,

The method for producing the container sealing body is as follows.

The container sealing body is composed of an upper layer and a lower layer.

An upper layer 400 on which the opening tabs are formed; And

And a lower layer (500) thermally bonded to the aluminum foil and the container,

Here, the upper layer is thermally bonded to the lower layer

The top layer 400 is composed of various kinds of plastic films, foams and the like. 4, the surface layer 410 located on the uppermost layer from the upper side is composed of a polyester film or a polypropylene film having a thickness of 0.012-0.05 mm and having no thermal adhesiveness. In some cases, the surface layer 410 may be printed.

The intermediate substrate layer 420 located under the surface layer 410 is a film or sheet made of a polyolefin foam having a thickness of 0.1-2 mm and is laminated on the surface layer 410 Loses.

The adhesion between the cap and the container 700 is increased by the elastic action of the intermediate base layer 420 when the cap and the container 700 are fastened. Since the foam sheet has an appropriate thickness, when the heat generated by the high-frequency induction heating is generated in the aluminum foil 520 in the lower layer 500, the heat insulating function for preventing the heat from being transmitted to the surface layer 410 is exhibited . Thereby preventing the cap from being deformed by the heat generated during the thermal bonding.

And the intermediate substrate layer 420 is laminated with a polyester film layer 430 having an appropriate thickness (0.03-0.2 mm) on the lower layer thereof. This polyester film 430 plays a very important role. That is, due to the strong tensile strength of the polyester film, a strong tensile strength is imparted to the entire upper layer 400 so that the opening tabs of the upper layer and the opening induction cutting bands of the ring type are not cut, When the container suture is removed, the open induction cut tape heat seal adhesive band of the upper layer 400 including the polyester film 430 previously cut at the time of the first partial opening and the second full open is cut into the lower layer 500, When the opening tab of the upper layer 400 is pulled in the upward direction, the lower layer of the aluminum layer and the heat-sealing resin layer are forced together in the upward direction.

The first heat-bonding resin layer laminated at the lower end of the upper layer is composed of a film having high heat- A second thermally adhesive resin having the same material as that of the first thermally adhesive resin layer is also formed on the upper surface.

The first thermally adhesive resin layer and the second thermally adhesive resin layer use a film of polyolefin resin composed of polyethylene resin or polypropylene resin having a thickness of 0.02-0.05 mm.

And a heat sealing adhesive layer 530 at a lower portion of the aluminum foil 520. The heat sealing adhesive layer is laminated with a film having heat adhesion to the container or coated with the resin material. In the case where the container 700 is made of polypropylene suitable for retort, the heat sealing adhesive layer 530 is made of a thermo-adhesive polypropylene film having an appropriate thickness of about 0.03-0.1 mm, 700 is made of glass, polyethylene, polyethylene terephthalate or the like, polyethylene, polyethylene terephthalate, polyethylene terephthalate, polyethylene terephthalate, Ionomer, Ethylene Vinyl Acetate, etc., or a polymer.
