JP2012046245A - Method of manufacturing plastic tube container - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the following problem: in a shape of a conventional plastic tube container, a function is not fully demonstrated even if a functional opening part such as a pump, a trigger and an airless pump, is attached to the container, and such a function is utilized in a mold container, however it is not adaptable to small-lot production of a wide variety of products and decoration, and moreover, when a contained amount is changed, an expensive new mold must be created.SOLUTION: The functional opening is attached to the plastic tube container, and in order to use the container while maintaining its function, a device is provided for mounting a pedestal to a container bottom part in a manufacturing process, and the pedestal is thermally welded to the container, Thereby, the container functions in a standing state. When the contained amount is changed, it can be changed by only changing cutting length of the tube, requiring no expensive mold. Moreover, just as the conventional tube container, the plastic tube container is adaptable to small-lot production of a wide variety of products and includes various decoration.

Description

  The present invention relates to a manufacturing method for using a plastic tube container as a variety of functional plastic tube containers upright with various functional parts up.

  In the conventional manufacturing method, plastic is extruded, formed into a tube shape, then cut at an arbitrary length, and the outlet and the screw portion are heat welded to one of the openings. A conventional manufacturing process diagram is shown in FIG.

  The cap part of the plastic tube container is turned upside down, and after filling the contents from the upper opening, it is heat-sealed in a straight line or by deformation and sealed. FIG. 4 shows a conventional filling process diagram.

  In the conventional manufacturing and filling methods described above, the plastic tube container main body is held in a hand and pushed out with a finger, so that it cannot meet the demand for a multifunctional container. Further, the container may be deformed as the contents are reduced during use, and the container may fall over without being able to stand on its own. In addition, when the inner volume of the molding container is changed, it is necessary to newly produce a molding die. Furthermore, although a molded container can be equipped with a multifunctional outlet, low cost, small lot production, and decoration in a small lot are difficult.

  In the present invention, a plastic tube container is made upright, and various outlets with various functions can be mounted on the upper part. The purpose is to provide decoration.

  And in order to achieve the said objective, this invention provides the apparatus which mounts a base in a container lower part after a manufacturing process or filling.

  Further, the second problem solving means is that when the outlet portion of the mechanism for applying pressure from above the pump or the like is mounted on the upper part of the container, the container is mounted with a pedestal for holding the shape so as to withstand the pressure without deformation. It is.

  Furthermore, when an airless pump is attached to the upper part of the container, a moving valve that moves upward as the contents are reduced is inserted into the tube.

  As described above, the plastic tube container manufacturing method of the present invention enables various functional outlets to be operated by attaching a base to the lower part of the plastic tube. Furthermore, the tube container can be provided by providing small lot production and decoration of a small lot that are conventionally possible.

  In addition, it can be provided at a lower price than conventional molded containers.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

  In the figure, reference numeral 1 denotes a process when a functional outlet other than the airless pump is mounted, and a container 4 is formed by inserting a pedestal 3 at the bottom and fixing by heat welding.

  2 shows a process of mounting an airless pump, and after inserting 5 movement valves from the bottom, insert 6 base, heat weld and fix to become 7 container.

  4. Stand up 4 containers, fill contents from 8 outlets, and attach 9 functional outlets such as pumps and triggers.

  7 containers are placed upright, 10 are filled with contents, and 11 airless pumps are installed.

  The completed embodiment of the present invention will be described below with reference to FIG.

  Reference numeral 1 denotes a container cross section before mounting a functional outlet other than the airless pump, 2 is a screw portion, and 3 is a pedestal portion.

  4 is a cross section of a container equipped with an airless pump, and 5 is a moving valve.

  6 is a cross section of a container equipped with a trigger.

  6 is a cross section of a container equipped with a trigger.
