Abstract

PURPOSE:To provide a method of producing a tubular container wherein printing can be easily carried out and the welding between an upper end of a barrel section forming cylinder and a shoulder outer periphery, between front and rear and opposite sides of a partition and the barrel section forming cylinder and between a head section and front and rear inner wall surfaces is made positive, by forming the barrel section forming cylinder previously, and also performing printing for decoration and others previously on the cylinder. CONSTITUTION:Previously, a synthetic resin barrel section forming cylinder 1 having the upper and lower end opened is formed, and also printing for decoration, description about the contents, the name of the maker, etc. is also made on the cylinder 1. The barrel section forming cylinder 1 on which printing has been already made is placed in a mold, a tubular container head section 4 having a mouth neck section 3 stood upward from the inner periphery of a shoulder 2 and a partition plate 5 dividing the inner space defined by the barrel section forming cylinder into the right half and the left half and the head section are welded, a barrel section forming cylinder upper end 1a and a shoulder outer periphery 2a are welded, and the front and rear and the opposite sides of the partition plate 5 and the front and rear and the inner wall surfaces of the barrel section forming cylinder 1 and the head section 4 are welded. Then the right and left lower ends of the barrel section forming cylinder 1 and the partition plate lower end are welded and the lower end of the barrel section forming cylinder is closed to produce a synthetic resin tubular container.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention divides the interior into two units, stores two types of stored items in the two units without mixing them, and separates them by squeezing the body. This invention relates to a synthetic multi-layered tube container that allows seeds to be poured out at the same time.

Conventional technology A synthetic resin tube container is conventionally known in which the interior of the tube container is divided into two units to store two types of stored items separately and can be poured out at the same time by squeezing the body. There was a drawback that the partition plate that divided into two parts easily moved when the body was squeezed to pour out the stored contents.

Problems to be Solved by the Invention By fixing the partition plate that divides the inside of the tube container into two, it is easy to manufacture a tube container that completely prevents mixing of two kinds of stored items, and the tube container body can be easily manufactured. An object of the present invention is to provide a manufacturing method that allows printing for decoration etc. on a section easily.

Means for Solving the Problem: A synthetic resin body forming tube 1 with both upper and lower end surfaces open is formed in advance, and decorations, descriptions of stored items, manufacturer's name, etc. are printed on the outer surface of the body forming tube. I'll keep it.

The above-mentioned printed body-forming tube 1 is placed inside a mold, and the tube container head portion 4 has the mouth portion 3 erected from the inner 8 edges of the shoulder portion 2 by injection molding, and the body-forming tube and the head portion are formed by injection molding. The upper end 1a of the trunk forming cylinder and the outer peripheral edge 2a of the shoulder part are welded to each other, and the front and rear sides of the partition plate 5 and the trunk forming cylinder 1 and It is formed by welding the front and rear inner wall surfaces of the head portion 4.

Next, the lower left and right ends of the trunk forming cylinder 1 + 1+ , I b
and the lower end of the partition plate are welded to close the lower end of the trunk forming cylinder 1 to form a synthetic grease-free tube container.

Embodiment When the lower end of the trunk forming cylinder is closed into a wooden block by squeezing from both left and right sides, the length of the wooden block becomes longer than the diameter of the trunk forming cylinder 1, so the lower end of the partition plate lower pile 6 (It is best to form it so that it gradually expands.) The filling of the contents into the two tube containers formed by the partition plates is performed with the bottom end of the body-forming tube closed (first, a cap is fitted to the mouth and neck), and after filling, the above-mentioned closure is performed. All you have to do is

Effects: Since the barrel forming cylinder is formed in advance and printing for decoration etc. is performed, printing is easier than printing after forming the tube container, and the printing is easier between the head part 4 and the partition plate 5. Formation is carried out by injection molding by placing the body forming tube inside a mold, so welding the upper end of the body forming tube and the outer periphery of the shoulder, and welding the front and rear sides of the partition plate, the body forming tube, and the head. Welding to the front and rear inner wall surfaces can be ensured.

Claims (1)

[Claims] After printing for decoration etc. on the outer surface of a pre-formed synthetic resin body forming tube with both upper and lower end surfaces open, the body forming tube is placed inside a mold and the shoulders are formed by injection molding. A tube container head portion with a neck and neck portion erected from the inner circumferential edge of the tube container, and a partition plate that bisects the internal space formed by the body forming tube and the head portion into left and right, are connected to the upper end of the body forming tube and the outer circumferential edge of the shoulder portion. and the front and rear sides of the partition plate are welded to the front and rear inner wall surfaces of the body forming cylinder and the head part, and then both the left and right lower ends of the body forming cylinder and the lower end of the partition plate are welded together. A method for manufacturing a synthetic resin tube container, which comprises welding and closing the lower end of a body-forming cylinder.
