Problems solved by technology

[0003] However, the oxygen barrier properties of these synthetic resins listed as specific examples are not sufficient, so there is a concern that the contents of the distribution package may be oxidatively deteriorated due to oxygen penetrating through the cap.

Embodiment 1

[0100]

[0101] PET(20μm) / AD(10μm) / EVOH(20μm) / AD(10μm) / HIPS[50 mass%]+GPPS[50 mass%](300μm) / AD(10μm) / LDPE[50 mass%]+HDPE [50% by mass](10μm) / LDPE(10μm)

[0102]

[0103] Ny(20μm) / EVOH(50μm) / AD(20μm) / LDPE(20μm)

[0104] The hard composite sheet and flexible composite film with the above-mentioned layer structure are produced by a co-extrusion method.

[0105] Next, at a predetermined position of the hard composite sheet, cut from the PET layer side to the PS layer to a depth of 50% of its thickness, and half-cut the hard composite sheet. Next, the half-cut hard composite sheet is heat-molded by a mold molding method to form a convex strip, which forms a discharge port for discharging the contents.

[0106] On the other hand, the flexible composite film is deep drawn to form a bag. After filling the bag with mayonnaise (manufactured by Yuyuichi Co., Ltd.) as a liquid food, it is combined with the rigid composite sheet formed with the convex stripe and heat-sealed. After that, it is c...

Embodiment 2

[0112] Except that the thickness of the EVOH in the rigid composite sheet of Example 1 was changed from 20 μm to 10 μm, in the same manner as in Example 1, a distributive packaged food (mayonnaise) was produced. The layer structure of the rigid composite sheet used is shown below.

[0113]

[0114] PET(20μm) / AD(10μm) / EVOH(10μm) / AD(10μm) / HIPS[50 mass%]+GPPS[50 mass%](300μm) / AD(10μm) / LDPE[50 mass%]+HDPE [50% by mass](10μm) / LDPE(10μm)

Embodiment 3

[0120]

[0121] PET(20μm) / / EVOH(20μm) / / HIPS[80% by mass]+GPPS[20% by mass](300μm) / AD(10μm) / LDPE(10μm) / LDPE(10μm)

[0122]

[0123] Ny(20μm) / EVOH[92% by mass] + oxygen-absorbing resin [8% by mass](50μm) / AD(20μm) / LDPE(20μm)

[0124] The hard composite sheet with the above-mentioned layer structure is produced by combining the co-extrusion method and the dry lamination method. In addition, the above-mentioned flexible composite film is produced by a co-extrusion method. The oxygen barrier layer of the flexible composite film is located in the range of 18-64% from the outer surface of the surface protection layer with respect to the thickness of the flexible composite film.

[0125] Using the above-mentioned rigid composite sheet and flexible composite film, the same method as in Example 1 was used to produce a food (mayonnaise) in a distribution package.

Abstract

The invention relates to an allocation packaging body, which has an allocation packaging body having a structure of welding container body of flexible member on the hard material cover, which does not prevent oxygen permeation from the cover at a higher level with opening, the cover has folding lines of half cutting part and a convex part formed with outlet opening on the central part of the surface. The allocation packaging body has a hard casing, and a flexible container body, the allocation packaging body is formed by welding a periphery part of the flexible container body on the back face of the hard casing, the hard casing, in the surface central part, has folding lines of half cutting part formed by the surface side and a convex part formed with outlet opening, and a convex part formed with an discharge port during bending, the flexible container body has a bag part for housing the content object, in the allocation packaging body, the hard casing is formed by hard complex sheet materials, the hard complex sheet is formed by laminating in sequence a printing receiving layer, a hard central layer and a casing sealing layer. The hard central layer has a polystyrene resin layer and a ethylene-vinyl alcohol copolymer resin layer configured at the printing receiving layer side.

Description

Technical field [0001] The invention relates to a distribution packaging body used for packaging various liquids and pastes. Background technique [0002] It is known that such a dispensing package can squeeze out the filled contents (such as jam, ketchup, seasoning, etc.) by simply bending the lid with one hand and squeezing it in this state. Liquid food such as dressing) (Patent Document 1). The distribution package has a structure in which a lid of a hard material and a container body of a flexible member are welded, wherein the lid of the hard material has a bending line provided with a half-cut part (ハ一フカツト) at the center of the surface, and use When being bent, the convex portion of the discharge port is formed, and the container body of the flexible member forms a bag portion (ポケツト portion) for accommodating the contents. In addition, as specific examples of the hard material constituting the cover, polyethylene, polyethylene terephthalate, and polystyrene copolymer can ...
