Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an easy-to-open sealed package, and more specifically, the present invention relates to an easy-to-open sealed package. .

Moreover, when taking out the contents, it is easy to remove the bulk #l.
This invention relates to a sealed package that is hermetically sealed with a sealing strength that allows it to be removed and is easy to open.

As a function of the package, the seal is sufficient to completely protect the contents during the manufacturing and ttta processes of a single item! has l',
In addition, when taking out the contents, the seal can be easily opened without destroying the base 44.The ease of opening is extremely high.
One important function is as a packaging body.

As a conventionally known technique regarding this openability, a glass container is coated with a silane coupling agent or coated with enalene vinyl acetate copolymer. It is known that foil is coated with niethylene vinyl acetate and heat sealed, but it is not suitable for food products due to hygiene reasons and sealing strength (500~tsOO#/15■It). There was melting as a body.

As a result of research in order to solve the problem of slanting, the present inventor found that a polyolefin fruit tree that was corona-treated with a sealant 111I in a packaging μm consisting of a container body and a lid made of crow. According to the sealing strength of 1 = width 11, -I sealant surface is made of amorphous polyester, titanium, or ethylene-vinyl acetate copolymer, and the rim of the container body is amorphous. By applying a polyester-based, titanium-based, or ethylene-vinyl acetate copolymer-based anchor coating agent, the sealing strength fI* can be improved even further, and the sealing method described above can improve the sealability of glass. It has been discovered that the lid can be peeled off from the mouth edge of the main body of the maker, and the present invention has been completed based on this knowledge.
The gist of the invention of Umbrella 1 is a glass container body and a polyolefin fruit tree If1 that has been subjected to corona treatment! It is an easy-open sealed package, characterized in that the sealant of the 11th period lid body is thermally bonded to the 0411 part of the main body of the container f1, and the sealant S is made of Il. One aspect of the invention of Ni-Wedge 2 is that it consists of a glass container body and a polyolefin fruit tree treated with corona 43, and that it is made of a glass container body and a polyolefin fruit tree. It consists of a bell body with a sealant coated with a non-crystalline polyester-based, titanium-based, and an ethylene-vinyl-coated anchor coating agent on the Lla surface, and the bottom of the phonograph body is Part t: An easy-to-open sealed package characterized in that a sealant of the crystalline substance shown in @+l is thermally bonded; Thermal bonding area I: Amorphous polyester, titanium, or ethylene seal vinyl co-coated anchor coating agent is coated with the container body and polyolefin coated with corona treatment. An easily openable sealed package comprising a lid having a sealant layer made of a resin layer, and a sealant of the jar is thermally bonded to a part of the main body of the 1IfI container.

Next, the main purpose of the invention of $4 is that the low IIB noodles are made of glass, and at least the lid is heated**, and the anchor coating agent is an amorphous polyester-based, titanium-based, and edelene-vinyl acetate copolymer-based. It consists of a container body coated with a polyolefin 4I1 multilayer coated with corona treatment.
and a lid body having a sealant layer coated with an anchor coating agent of di-amorphous polyester yarn, titanium-based, or ethylene/vinyl acid co-enriched system, and the rim of the container body s(; An easily openable sealed package characterized in that the sealant layer of the metal body is thermally bonded.

Hereinafter, the present invention will be described with reference to the drawings and documents.
