Embodiment

[0100] Hereinafter, the present invention will be described with reference to examples.

[0101] Described below are the methods for measuring various characteristics and physical properties and the container main body (bottle) employed in the following examples.

[0102]

[0103] A multilayer direct blow molded bottle having the following layer composition and a capacity of 200 ml was formed by a known method and used in the following experiments.

[0104] Bottle A: direct blow molding multilayer bottle with five types of nine layers

[0105] Layer composition: inner layer / adhesive layer / liquid diffusion inhibiting layer / adhesive layer / main layer / adhesive layer / oxygen barrier layer / adhesive layer / outer layer

[0106] Inner layer: low-density polyethylene containing 5 wt% silica (average particle diameter of silica = 5 μm)

[0107] Adhesion layer: Acid-modified polyethylene

[0108] Liquid diffusion suppression layer: Ethylene-vinyl alcohol copolymer (EVOH)

[0109] Main...

experiment example 1 to experiment example 3

[0147] Bottle A (a direct blow-molded multilayer bottle having five types of nine layers) was prepared as a container main body.

[0148] To the inner surface of bottle A, medium-chain fatty acid triglyceride as a lubricating liquid was coated in the amount shown in Table 1 by an air spray method using an air brush. A bottle having an inner surface coated with a lubricating liquid was used to confirm the pool of the above-mentioned lubricating liquid and to conduct a test of slipperiness of the fluid content. The results are shown in Table 1.

[0150] Bottle B (a direct blow-molded multilayer bottle having five types of nine layers) was prepared as a container body. The amount of medium-chain fatty acid triglyceride shown in Table 1 was applied by the same method as in Experimental Example 1, followed by confirmation of a pool of lubricating liquid and a test of slipperiness of the fluid content. The results are shown in Table 1.

[0151] [Table 1]

[0152]

[0153] Table 1 shows that in Experimental Example 1 to Experimental Example 3, unevenness was formed on the inner surface of the bottle and the inner surface with unevenness was coated with a lubricating liquid. In Experimental Example 1 and Experimental Example 2, the formation of a pool of lubricating liquid was observed. In these Experimental Examples 1 and 2, the slipperiness to the contents was good. In Experimental Example 3, the formation of liquid pools was not observed, and the slipperiness to the contents was poor.

Abstract

A package comprising a container body 1 in which liquid contents 3 are accommodated such that a headspace 7 remains, wherein the package is characterized in that: protrusions and recesses are formed along the entirety of an inner surface 1a of the container body 1; the inner surface 1a of the container body 1 comprising the protrusions and recesses is covered by a lubricating liquid 30 that is immiscible with the liquid contents 3; a covering layer of the lubricating liquid 30 is interposed between the inner surface 1a and the liquid contents 3; and, with the container body 1 being held erect,a reservoir 31 of the lubricating liquid 30 that forms the covering layer is formed at a peripheral edge part of the upper-end surface of the liquid contents 3 accommodated within the container body1.

Description

technical field [0001] The present invention relates to a package comprising a container body containing fluid contents. More specifically, the present invention relates to a package body including a container main body having an inner surface provided with irregularities, and the inner surface is formed with a coating layer of a lubricating liquid for improving slipperiness of fluid contents. Background technique [0002] Since plastic containers can be easily formed and manufactured at low cost, they are widely used in various fields. In particular, from the viewpoint of easy extrusion of the contents, a bottle-shaped olefin-based resin container is preferably used as a container for containing viscous slurry or pasty contents such as ketchup, wherein the bottle-shaped olefin-based resin container It is formed by direct blow molding (blow) and has a container wall having an inner surface formed of an olefin-based resin such as low-density polyethylene. [0003] Bottles c...
