Embodiment

[0099] The present invention will be described below with reference to examples.

[0100] The measurement methods and container bodies (bottles) performed in the following examples for measuring the corresponding characteristics and physical properties are described below.

[0101]

[0102] Multilayer direct blow molded bottles with the following layer composition and 500 mL capacity were formed by known methods and used in the following experiments.

[0103] Bottle A: Direct blow molded multilayer bottle with 5 types of 9 layers

[0104] Layer composition: inner layer / adhesive layer / liquid diffusion prevention layer / adhesive layer / main layer / adhesive layer / oxygen barrier layer / adhesive layer / outer layer

[0105] Inner layer: low density polyethylene

[0106] Adhesive layer: acid-modified polyethylene

[0107] Liquid diffusion prevention layer: Ethylene-vinyl alcohol copolymer (EVOH)

[0108] Main Layer: Low Density Polyethylene (LDPE)

[0109] Oxygen Barrier: Ethylene ...

experiment example 1

[0144] Bottle A (a direct blow-molded multilayer bottle with 5 types of 9 layers) was prepared as a container body.

[0145] Medium-chain fatty acid triglyceride as a lubricating liquid was applied to the inner surface of bottle A in the amount shown in Table 1 by an air-brush method. A bottle whose inner surface was coated with a lubricating liquid was used to form a pool of the aforementioned lubricating liquid, and was subjected to tests of slip properties with respect to fluid and peelability with respect to fluid. The results are shown in Table 1. Here, the contact angle of the lubricating liquid with respect to the low density polyethylene surface is smaller than the contact angle of the fluid with respect to the low density polyethylene surface.

experiment example 2

[0147] Slip property with respect to fluid and peelability with respect to fluid were tested in the same manner as in Experimental Example 1, except that a pool of lubricating liquid was not formed. The results are shown in Table 1.

Abstract

A package comprising a container body in which fluids are accommodated so as to leave a head space, wherein the package is characterized in that the inner face of a container body 1 is covered with alubricating liquid 30 immiscible with a fluid 3, the covering layer of the lubricating liquid 30 is interposed between the inner face and the fluid 3, and, while the container body 1 is held in an upright state, a liquid reservoir for the lubricating liquid 30 is formed in the peripheral edge of the top face of the fluid 3 accommodated in the container body, with the contact angle of the lubricating liquid 30 with respect to the inner face being smaller than the contact angle of the fluid 3 with respect to the inner face.

Description

technical field [0001] The present invention relates to a package comprising a container body containing a fluid. More specifically, the present invention relates to a package having an inner surface on which a coating layer of a lubricating liquid for improving slippage with respect to a fluid is formed. Background technique [0002] Since plastic containers can be easily formed and produced at low cost, they are widely used in various fields. In particular, from the viewpoint of easily squeezing the contents, a bottle-shaped olefin resin container is preferably used as a container for accommodating viscous slurry or paste-like contents such as ketchup, wherein the bottle-shaped olefin resin container has a container wall and consists of Formed by direct blow molding, the container wall has an inner surface formed from an olefin resin such as low density polyethylene. [0003] Bottles containing viscous contents are typically stored upside down so that the contents can be...
