JP3016080B1 - Manufacturing method of empty can storage container for beverage etc. - Google Patents

Abstract

An object of the present invention is to reduce the product cost by molding an empty can storage container that has been conventionally formed by a method of extrusion using a mold by an injection blow method without using a mold. And A waste liquid outlet 1 is formed at the top B of a body A of a container integrally formed by an injection blow method, and an empty can inlet 2 is formed at a bottom C of the body A. Thereafter, each of the crown B and the bottom C is cut and separated from the body A at a predetermined position, and the separated crown B is fitted and adhered to the cut surface of the bottom C with the waste liquid discharge port 1 upward. After the cut and separated bottom part C is detachably attached to the cut surface of the top part B of the main body part A, the whole container is turned upside down and used.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing an empty can container for beverages or the like by an injection blow molding method.

[0002]

2. Description of the Related Art As a conventional technique, a lid portion and a body portion of a container are separately formed by an extruder using a male and female mold, and then a lid portion provided with an empty can inlet is provided on the body portion. And made it an integral container.

[0003]

According to the prior art, there is a problem that the cost of the mold is increased due to the extrusion molding method, and the depreciation burden is naturally large, which reflects the high product cost. there were. An object of the present invention is to solve these problems.

[0004]

In order to solve the above problems, the inventor has invented a method of integrally manufacturing empty can storage containers for beverages and the like by an injection blow method after trial and error. That is, a mold having a shape of an empty can storage container for beverages or the like is prepared, and a bottom-shaped container is formed by an injection blow method using a raw material of polyethylene terephthalate in the mold. The shape of the bottom container in this case is
The bottom of the body is formed in a dome shape, and an empty can inlet is formed on the side surface of the bottom. A waste liquid outlet is provided at the top of the body, that is, at a portion where the chuck of the injection blow device is held. Thus, the molded bottom-shaped container is cut and separated at a predetermined position immediately below the top of the head and at a predetermined position of the dome-shaped bottom, and the cut dome-shaped bottom can be detachably mounted on the cut surface. At the same time, the whole container having a flat bottom is assembled by inverting the cut and separated top part upside down and fitting and bonding to the cut surface of the top part, and after assembling, the whole container is turned upside down, the dome The bottom part having an empty can inlet is located at the top, and the top part having the waste liquid outlet is located at the bottom so as to form an empty can storage container for beverages and the like.

[0005]

[Function] A container integrally molded into a bottom shape is divided into three parts: a top part provided with a waste liquid discharge port, a body part, and a dome-shaped bottom part provided with an empty can input port, and the divided top part is turned upside down and cut. If the whole container is assembled by fitting and bonding the cut surface so that the surface is on the top, and the dome-shaped bottom is detachably attached to the cut surface, then the entire container is turned upside down, A top with an empty can input port is detachably formed at the top of the body, and a flat bottom is formed by fitting a top with a waste liquid discharge port to the cut surface below the body. Thus, the whole container is constituted.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described by way of an embodiment. A is a body trunk, B is a crown, and the crown B is a body trunk A.
And is to be cut off and separated from the main body body A at a predetermined position, and a blow-out portion pinched by a chuck of the injection blow device serves as a waste liquid discharge port 1. C is a dome-shaped bottom of the main body A, which is to be cut off and separated from the main body A at a predetermined position, and has an empty can inlet 2 provided on a side surface. After the head B and the bottom C are cut and separated, the head A is fitted and adhered to the cut surface in a state of being turned upside down, and the bottom C is detachably mounted on the cut surface.

[0007]

According to the present invention, the lid portion and the container body portion required for manufacturing an empty can storage container for beverages or the like by the extrusion molding method using male and female molds as in the prior art. Since molds for two systems are not required and the cost of the molds is greatly reduced, not only the depreciation burden is reduced and the product cost is reduced, but also the plastic bottle can be molded by the injection blow molding method. In addition, even if a company specializes in manufacturing PET bottles with injection equipment, there is an economic effect that the use of existing equipment can be expanded without introducing a new extrusion molding apparatus. In addition, since the injection port of the injection blow naturally forms the waste liquid discharge port, there is no need to form the waste outlet, and the processing step is streamlined.

Claims (1)

(57) [Claims] 1. A waste liquid outlet 1 is formed at the top B of a main body A of a container integrally formed by an injection blow method, and an empty can inlet 2 is formed at a bottom C of the main body A. After molding, each of the crown B and the bottom C is cut and separated from the body trunk A at a predetermined position, and the separated crown B is separated.
Is turned upside down and fitted and adhered to the separated cut surface of the top part B, while the cut and separated bottom part C is detachably mounted on the separated surface to assemble the whole container. A method for producing an empty can storage container for beverages or the like, characterized in that the container is used upside down.
