Description

Peer tube equipped with detachable cap {P.E. TUBE WITH SEPARATABLE CAP}

The present invention manufactures a tube tube package that is formed by injection molding the injection cap and the detachable cap having an insertion rod integrally to the main body and a plurality of the tube is opened in the lower part of the lower body of the main body, the tube After filling the filling parts into the opened parts of the respective PIP tubes constituting the package, and bonding the sealed parts through the ultrasonic bonding machine and sealing them, cutting them with each PTube tube through a cutting press and then completing the packing. The present invention relates to a tube having a detachable cap.

Known cartridges, ie plastic containers, capable of sealing the flowable material therein by adhesive or press bonding, are produced by injection molding by use of a mold.

The plastic container provides a separate lid to prevent the filling of the inside from leaking to the outside, which increases the production cost of the plastic container, and requires a separate manual or automated operation to couple the lid to the plastic container. There is a problem.

In addition, in order to compensate for the disadvantages of the plastic container, there is a product that is filled with the contents of the container and then sealed, and the lid is bonded to the plastic container, which is commercially available. There is a need for a flag station, and the lid bonded to the container may be lost in the transfer step.

On the other hand, there are many kinds of plastic products used in the raw materials of the plastic container, generally polyethylene products are used a lot.

The polyethylene is a chain-like polymer material produced by the polymerization of ethylene, and polymerizes ethylene produced in the naphtha portion during the crude oil fractionation process to make polyethylene having the following formula (sometimes, there are branches). CH2 = CH2? -CH2-CH2-CH2-CH2- According to the polymerization method, various kinds of polyethylene are produced. Low density polyethylene (soft polyethylene) and high density polyethylene (hard polyethylene) are the main products, and low density polyethylene is generally manufactured.

Low-density polyethylene is produced by heating at high pressure of 1,000 atm and 200 ° C or higher using a small amount of air as a catalyst, and thus generally referred to as high-pressure polyethylene. Its density is about 0.91, its branches are not enough, and its crystallization is about 65%, so it becomes soft and stretches well. The tensile strength is slightly small, but the impact resistance is large. Easy to process or use

High-density polyethylene uses a so-called Ziegler-Natta catalyst (a complex salt catalyst consisting of titanium tetrachloride and triethylaluminum) to polymerize ethylene at about 70 캜 and 10 atm. Generally referred to as low pressure polyethylene, softening point (hardening), firmness, and strength are all large, but the elongation and impact resistance are small and the touch is hard. It has few branches, large crystallinity, reaching 85%, and density over 0.95.

In addition, there are medium pressure polyethylenes produced by the medium pressure polymerization method, and the medium pressure polymerization methods include the Philips method and the standard method. The Philips method is a method of polymerization at 70 atm and 80 ° C using chromium oxide as a carrier as a catalyst, and the standard method is a method of polymerization at 150 ° C or more and 100 atm or less using various catalysts such as molybdenum. There is also a method called using ultra high pressure 3,000 atm, all of which produce high density polyethylene.

Most molecular weight of polyethylene is 50,000 to 100,000. As mentioned above, since it is composed of only CH2, it has excellent electrical insulation, and its volume intrinsic resistance reaches 1019 가장 · cm, and as shown in the structural formula, it is the best as a high-frequency insulation material because it is symmetrical with the chain of C as the center. Do. Except for the fact that the heat deformation temperature of the high-pressure polyethylene under charge is 50 ° C., and the low-pressure method is around 80 ° C., it is an excellent material for electrical materials.

In addition, it is used for various containers, packaging films, fibers, pipes, packings, paints, and the like. Buckets and cups are made by extrusion molding, and industrial chemical containers, liquid detergent containers and the like are made by blow molding.

The present invention was devised to solve the above problems, and the detachable cap is integrally injection-molded through the mold work and the injection work, and the PPI tube package is connected to a plurality of PI tubes whose bottom is opened. After manufacturing, the filling material through the filling machine to the opened portion of each of the tube tube constituting the tube tube, and then bonded and sealed by the ultrasonic bonding machine to each tube through the cutting press It is an object of the present invention to provide a PTube equipped with a detachable cap to complete the packaging after the cutting operation.
