Benefits of technology

Enables the creation of containers with tailored properties and designs for various parts, enhancing barrier properties, heat retention, and visual appeal while maintaining manufacturing efficiency using standard blow molding equipment.

Problems solved by technology

Thus, to give various functions or characteristics (e.g., barrier properties or heat retaining properties) to a container, limited methods are available, a typical example of which is changing the material included in the preform.
In particular, it is difficult to give different functions or characteristics to different parts (e.g., trunk part and bottom part) of a container.

first embodiment

Variation of First Embodiment

[0327]A variation of the first embodiment of the present invention will now be described with reference to FIGS. 16, 17, and 18(a) to 18(f).

[0328]According to the variation illustrated in FIGS. 16, 17, and 18(a) to 18(f), a cylindrical plastic member 40a is used instead of the plastic member 40a having the trunk part and the bottom part.

[0329]In the composite container 10A illustrated in FIG. 16, the plastic member 40 extends from the shoulder part 12 to a lower part of the trunk part 20 of the container body 10, but does not reach the bottom part 30. Further, in the composite preform 70 illustrated in FIG. 17, the plastic member 40a is brought in close contact with the preform 10a to cover only the trunk part 20a of the preform 10a. More specifically, the plastic member 40a covers the trunk part 20a excluding its lower part and the part 13a corresponding to the neck part 13 of the container body 10.

second embodiment

Variation of Second Embodiment

[0399]A variation of the present invention will now be described with reference to FIGS. 26, 27, and 28(a) to 28(f).

[0400]According to the variation illustrated in FIGS. 26, 27, and 28(a) to 28(f), an inner label member 60a and a plastic member 40a both in a cylindrical shape are used instead of the inner label member 60a and the plastic member 40a both having the trunk part and the bottom part.

[0401]In the composite container 10A illustrated in FIG. 26, the inner label member 60 and the plastic member 40 extend from the shoulder part 12 to a lower part of the trunk part 20 of the container body 10, but do not reach the bottom part 30. Further, in the composite preform 70 illustrated in FIG. 27, the inner label member 60a and the plastic member 40a are brought in close contact with the preform 10a to cover only the trunk part 20a of the preform 10a. More specifically, the inner label member 60a and the plastic member 40a cover the trunk part 20a excludi...

Abstract

A composite container which can be given various functions and characteristics; a method for producing such composite container; a preform; and a composite preform. A composite container according to the present invention that includes a container body which is made of a plastic material; and a plastic member disposed on the outer surface of the container body, wherein the container body and the plastic member are integrally inflated by means of blow molding, and wherein the plastic member includes a colored layer and / or a print layer where a print is made.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a division of U.S. application Ser. No. 15 / 529,213, filed May 24, 2017, which is the National Stage entry of International Application No. PCT / JP2015 / 084194, filed Dec. 4, 2015, which designated the United States, the entireties of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a composite container, a composite preform, a plastic member, and a method for producing a composite container.BACKGROUND OF THE INVENTION[0003]Recently, bottles made of plastics have been more commonly used for containing liquid contents such as drink or food. Liquid contents are contained in such plastic bottles.[0004]Such a plastic bottle for containing liquid contents is produced by inserting a preform into a die and performing biaxial stretch blow molding on the preform.[0005]In a conventional biaxial stretch blow molding method, a preform containing a single-layer material, multi-lay...
