Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a paper container having a polyolefin resin dispenser.

[Prior Art] A pouring tool made of a polyolefin-based resin is inserted from the inside of the paper container into an opening formed in the paper container, and a flange portion of the pouring tool has an inner peripheral surface side of the paper container. The paper container fixed to the paper is widely used as a liquid paper container for filling beverages and the like.

The paper container is made of a laminated sheet for a paper container whose front and back double-sided layers are composed of a polyolefin resin layer, and the flange portion of the spout is heat-bonded to the inner peripheral surface layer of the paper container. It is common that the configuration is different.

[Problems to be Solved by the Invention] By the way, in the conventional paper container described above, a polyolefin-based resin layer is formed when a laminated sheet that is a molding material for the paper container is formed, or a paper container is formed using the laminated sheet. In some cases, the polyolefin resin undergoes thermal decomposition to produce volatile components such as aliphatic hydrocarbons, and these volatile components migrate into the internal filler contained in the paper container. Not only is it a factor causing a change in taste and an offensive odor, but the polyolefin resin layer that is the inner peripheral surface layer of the paper container adsorbs the flavor component in the orange juice that is the inner filler. However, it has the drawback that the flavor of the filling material is easily impaired because it is easily transmitted.

Therefore, as a paper container having a property of retaining flavor components, the inner peripheral surface layer of the paper container has a glass transition temperature.
Paper containers having a linear saturated polyester resin layer or an ethylene-vinyl alcohol copolymer resin layer at 40 ° C. or higher have been studied.

Therefore, a linear saturated polyester resin or an ethylene-vinyl alcohol-based copolymer resin having heat adhesion suitability with the inner peripheral surface layer of the paper container for the paper container having the retention performance of the flavor component is prepared. When I tried to apply a pour tool consisting of an integral molded body, the former pour tool with a linear saturated polyester resin, the rigidity of the linear saturated polyester resin that is the raw material for molding is high, cracks occur in the thin portion,
Furthermore, in the case of a spout having a pull ring, it has the drawback that the opening cannot be formed by a bull ring, and the latter spout made of an ethylene-vinyl alcohol copolymer resin is The ethylene-vinyl alcohol copolymer resin, which is a raw material for molding, has a high crystallization rate and is accompanied by the same adverse effects as in the case of the above-mentioned linear saturated polyester resin spouting tool.

On the other hand, each of the first and second inventions is a paper container having a flavor characteristic, and has a strong heat-bonding portion between the synthetic resin spout and the paper container, and The present invention provides a paper container that is free from cracks in the thin portion of the spout, and in the case of a spout having a pull ring, the opening cannot be formed by the pull ring.

[Means for Solving the Problems] A paper container provided with the pour-out device according to the first and second inventions is made of a polyolefin resin from the inside of the paper container at an opening formed in the paper container. The spout is inserted, and the flange portion of the spout is fixed to the inner peripheral surface side of the paper container.

In the paper container of the first invention, the inner peripheral surface layer of the paper container is composed of a linear saturated polyester resin layer having a glass transition temperature of 40 ° C. or higher, and the flange of the spouting tool. And an inner peripheral surface layer of the paper container, an interposing member composed of a laminated sheet having a surface layer made of a linear saturated polyester resin layer and a back surface layer made of a polyolefin resin layer, The surface layer of the sheet is the inner peripheral surface layer of the paper container, and the back surface layer of the laminated sheet is abutted so as to contact the flange portion of the spout, respectively, and the inner peripheral surface layer of the paper container. The interposer member and the flange portion of the spout are heat-bonded.

Further, in the paper container of the second invention, the inner peripheral surface layer of the paper container is composed of an ethylene-vinyl alcohol-based copolymer resin layer, and moreover, the flange portion of the spout and the paper container. An interposing member comprising a laminated sheet having a surface layer formed of an ethylene-vinyl alcohol copolymer resin layer and a back surface layer formed of a polyolefin resin layer is provided between the inner peripheral surface layer and the laminated sheet. The inner surface layer of the paper container, and the back surface layer of the laminated sheet is brought into contact with the flange portion of the spout to contact the inner surface layer of the paper container. The mounting member and the flange of the spout are
It is heat-bonded.

In the paper container of the first invention, the linear saturated polyester resin layer forming the inner peripheral surface layer of the paper container has a temperature lower than the glass transition temperature of the polyester resin forming the polyester resin layer. In order to exhibit excellent aroma-retaining performance, the inner filler in the paper container is usually placed in an atmosphere of less than 40 °. It is composed of a linear saturated polyester resin having a glass transition temperature of 40 ° or more so as to exhibit the aroma retaining performance.

Further, when the linear saturated polyester resin layer is formed of a resin having a low crystallinity of, for example, a crystallinity of 10% or less, for example, an inner filling material such as orange juice for a paper container is used. Even when subjected to heating such as when the filling is carried out by hot filling, the heat-adhesive properties of the polyester resin layer are not impaired, and the heat-adhesive portion of the sealing portion formed after filling the inner filler is excellent. Adhesive strength can be obtained.

Examples of the linear saturated polyester resin having a glass transition temperature of 40 ° C. or higher which constitutes the inner surface layer include ethylene glycol, propylene glycol, 1,4-butanediol, 1,4
An alcohol component such as cyclohexanedimethanol,
A co-condensation polymer of an aliphatic dicarboxylic acid such as adipic acid and sebacic acid and a dicarboxylic acid component such as an aromatic dicarboxylic acid such as terephthalic acid, isophthalic acid and diphenyldicarboxylic acid, specifically ethylene glycol and terephthalic acid , Ethylene glycol and isophthalic acid and terephthalic acid, 1,4-cyclohexanedimethanol and ethylene glycol and terephthalic acid, and propylene glycol and isophthalic acid and terephthalic acid. .

Incidentally, in the case of a co-condensation polymer in which the aliphatic dicarboxylic acid component in the acid component is 10% by weight or more, the saturated polyester resin layer formed by the co-condensation polymer has a tendency that its aroma retention performance is deteriorated. Is not preferable.

Further, the linear saturated polyester resin layer having a glass transition temperature of 40 ° C. or more has poor stability when the layer thickness is less than 3 μ, and hardens when the layer thickness exceeds 60 μ. The thickness of the resin layer is preferably in the range of 3 to 60 μ, since the container moldability of the laminated sheet, which is a material for forming a paper container, deteriorates.

As the outer peripheral surface layer of the paper container, it is preferable to use a polyolefin-based resin layer having water-proof performance from the outside and simultaneously having excellent thermal welding performance between the paper container and the saturated polyester resin layer. .

This polyolefin resin layer is, for example, low density polyethylene, medium density polyethylene, high density polyethylene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-methyl acrylate copolymer, ethylene-α. It can be composed of an olefin copolymer, and further, formed of polypropylene or the like in a thickness of about 3 to 150 μm.

Between the inner peripheral surface layer and the outer peripheral surface layer in the paper container, for example, a paper composite base material layer formed by laminating an aluminum foil, a paper layer, an olefin resin layer, a stretched polyester film layer, etc. is used, In particular, by interposing a stretched resin film layer between the paper layer and the low crystalline linear saturated polyester resin layer having a glass transition temperature of 40 ° C. or more, which is the inner peripheral surface layer of the paper container, it has excellent properties for bending. It can be used as a paper container.

The form of the paper container can be various types such as a gobel top type and a brick type.

The interposing member interposed between the inner peripheral surface layer of the paper container and the flange portion of the pouring tool is, as described above, composed of a surface layer composed of a linear saturated polyester resin layer and a polyolefin resin layer. The back surface layer comprises a laminated sheet having a back surface layer, the front surface layer is made of the same saturated polyester resin as the inner peripheral surface layer of the paper container, and the back surface layer is made of the same polyolefin material as the raw material for molding the spout. Depending on the resin

The mounting member may have a two-layer structure including the front surface layer and the back surface layer, and between the front surface layer and the back surface layer, for example,
It has a biaxially oriented polyethylene terephthalate film, a biaxially oriented nylon film, a biaxially oriented polypropylene film, an aluminum foil, a composite layer of a combination of two or more of these, and a core layer made of an adhesive polyolefin resin layer or the like.

In the paper container of the second invention, the ethylene-vinyl alcohol copolymer resin forming the inner peripheral surface layer of the paper container has an ethylene content of less than 40 mol% and the temperature required for heat sealing is It is not practical because it becomes high, and it is not practical because the ethylene content becomes high, and those with an ethylene content of more than 60% have a high tendency to adsorb the fragrance component in the internal filler. It is preferable to use an ethylene-vinyl alcohol copolymer resin having an ethylene content of 40 to 60 mol%.

Further, in the resin layer made of the ethylene-vinyl alcohol copolymer, when the thickness of the layer is less than 5 μ, the stability of the resin layer becomes low, and when it exceeds 40 μ, the impact resistance becomes low.
