JPH05305975A - Container equipped with ultraviolet shielding function - Google Patents

Abstract

PURPOSE:To prevent deterioration from occurring during transportation and storage by a method wherein synthetic resin to be used for making an inner bag or a container to be incorporated in a polyhedral carton is made to contain a material having ultraviolet shielding function. CONSTITUTION:Synthetic resin to be used for making an inner bag or a collapsible container to be incorporated in a collapsible carton is made of low-density polyethylene or the like that is made to contain inorganic ultraviolet shielding material such as titanium oxide, silicon oxide, ferrous oxide, calcium carbonate, magnesium carbonate, graphite and others, or organic ultraviolet absorber such as salicylic acid derivative, benzophenone derivative, benzoriazole derivative, cyanoacrylate derivative and others. The aforementioned synthetic resin may be made either in transparency or opacity.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing and transporting UV-curable printing ink, paint, etching resist ink or solder resist ink.

[0002]

2. Description of the Related Art Conventionally, as a container for storing and transporting UV-curable printing ink, paint, etching resist ink or solder resist ink, etc., curing reaction of the contents by ultraviolet rays during storage and transportation is prevented. Therefore, mainly metal pail, or so-called 1
Doo cans have been used. However, the empty cans after using the contents take up space before processing, and the disposal of the empty cans is complicated.

On the other hand, a container in which a foldable polyhedral carton is provided with a foldable synthetic resin container manufactured by an inner bag or blow molding is well known. This container has no problem in strength during storage or transportation of fluid contents, and can be folded after use, and the container itself can be easily disposed. However, the container having such a structure has an insufficient shielding of ultraviolet rays and is not suitable as a container for contents having reactivity with ultraviolet rays as described above.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a fluid content having an ultraviolet ray shielding function and having reactivity with ultraviolet rays, particularly ultraviolet ray curable printing ink, paint, etching resist ink or solder resist ink. It is an object of the present invention to provide a container which is suitable for storage and transportation such as, and which can be easily disposed of after use.

[0005]

The container of the present invention is a container in which a foldable polyhedral carton has a synthetic resin inner bag or a foldable synthetic resin container built therein. The synthetic resin used is characterized by containing a substance having an ultraviolet shielding function,
A container for fluid contents having reactivity with ultraviolet rays, especially for ultraviolet-curable printing ink, paint, etching resist ink or solder resist ink.

The polyhedron carton used in the present invention is foldable except when it is in use, and in the case of providing a spout and a cap for putting in and taking out the fluid contents into and from a container, the polyhedron carton is used as a spout. You may provide a hole in a corresponding part.

The synthetic resin used for the inner bag provided inside the polyhedral carton or the foldable container made of synthetic resin is not particularly limited, but examples thereof include high and low density polyethylene, polypropylene, polyvinyl chloride, vinylidene chloride, Polyamide, polyester, EVA, etc. can be mentioned.

The ultraviolet ray shielding means of the present invention is based on the fact that the synthetic resin used for the inner bag provided inside the polyhedron carton or the foldable container made of synthetic resin contains a substance having an ultraviolet ray shielding ability. In the present invention,
The substance having an ultraviolet ray shielding function may be any substance that shields or absorbs ultraviolet rays by absorbing or absorbing them. Examples include titanium oxide, silicon oxide, iron oxide, zinc, calcium carbonate, magnesium carbonate, graphite, and organic UV absorbers such as salicylic acid derivatives, benzophenone derivatives, benzotriazole derivatives, and cyanoacrylate derivatives. You can The synthetic resin containing these may be transparent or opaque.

[0009]

INDUSTRIAL APPLICABILITY The container of the present invention has a sufficient UV-shielding effect even though it can be easily disposed of after use, and therefore has a flowable content reactive with UV rays, particularly UV-curable printing. Ink, paint, etching resist ink, solder resist ink, etc. can be stored for a long period of time, and the quality of these contents can be prevented from deteriorating even during outdoor handling such as transportation.
