Multi-thread jar, manufacturing method thereof and multi-thread straight-through subsection

Abstract

The invention discloses a multi-thread tank, a multi-thread direct-communication type section, and a manufacture method thereof. The product can be used for secondary utilization; the proposal of the invention is that a tank body part below the covering mechanism of a plastic tank inlet part is provided with a sealed or open thread which enwinds a longitudinal shaft to be used for being selected;therefore, not only the covering mechanism of the tank inlet of the original design can be directly utilized, but also the covering mechanism of the original tank inlet part can be cut by a cutting method, and the covering mechanism with the tank body containing the section of the thread can be taken as the tank inlet during the secondary utilization process; meanwhile, the tank inlet structure and the tank body length or volume are correspondingly selected. If the tank bottom part below the thread is cut off, a direct-communication type section is formed; the multi-thread tank and the multi-thread direct-communication type section can be connected with each other by corresponding threads, thus leading functions thereof to be extended. The performances of thin thread and erected thread atthe product body are realized by the manufacture method, namely, the thread is formed by the bidirectional tensioning, the blow molding and the matching with the die of the injection blank. The product is suitable for the package of domestic articles and achieves the aim of waste utilization.

Description

technical field [0001] The present invention relates to a packaging container and its manufacturing method, and further relates to a plastic jar-shaped container whose function is improved through the combined design of its structure, material and manufacturing method and its manufacturing method. Background technique [0002] In the past, a large number of plastic cans (bottles) used for packaging, such as beverage cans (bottles), medicine cans (bottles), etc., were discarded after one-time use—that is, after the packaged items were used up. The function is single. For example, the mouth of the can can't hold things larger than the mouth of the can. That is to say, their caliber, the closing mechanism of the mouth, and the volume cannot be changed, and they cannot be selected, so that they cannot pack items of other shapes and volumes. , resulting in no other use. On the one hand, these discarded even high-cost and exquisite cans may still have a high residual value that h...

Problems solved by technology

However, such reusable cans have encountered the following design problems: integrating the functions and structures required by the two uses into one "can" will easily cause the two to differ in shape, manufacturing process, commercial principles, and use. Conflict and incompatibility of factors such as effects, such as: caliber size, tank wall thickness, tank rigidity, tank deformation, high pressure resistance, sealing requirements, economic costs, etc.
