Combined type packaging unit and container manufactured through same

Abstract

The invention provides a packaging unit combination for forming a container. The packaging unit combination is characterized in that the packaging unit combination comprises a unit body A and a unit body B. The unit body A is plate-shaped and is provided with a folding mark for turnover; the unit body B comprises a circulation assembly and a contact area, the circulation assembly at least comprises a neck part and a cover, the contact area is arranged around the neck part in a surrounding manner, the neck part is tubular, and the cover is arranged at the top end of the neck part and used for opening and closing the neck part; and the unit body A forms a container semi-finished product with an unshielded top through the folding mark, and the neck part covers the top of the container semi-finished product and is sealed with the container semi-finished product through the contact area. Compared with the prior art, the packaging unit provided by the invention is simple in preparation process and convenient to operate, waste gas emission is reduced, sealing and bonding installation after filling can be realized, a cleaning process for injection molding residues is omitted, and residues of injection molding smell are avoided; and in the preparation process, chemical glue and the like do not need to be used, so that the problem of secondary pollution is well avoided.

Description

technical field [0001] The invention relates to the packaging field, in particular to a combined packaging unit and a container made using the packaging unit. Background technique [0002] In recent years, the packaging material market has developed rapidly, and new forms of packaging containers are constantly pouring into the market, especially in the fields of dairy products and beverages. The appearance and comfort of packaging containers have become more important factors to attract consumers. . Most of the existing containers are made of cardboard as a base material. The cardboard as a whole can be folded independently through reasonable creases to form a container. This cardboard appears in the form of a sheet or roll and is put into the production line for production. [0003] The first purpose of using the container is to be able to store objects with strong fluidity; the second is to facilitate the use of the user and the convenience of the manufacturer for sale. ...

AI Technical Summary

Problems solved by technology

The production process of this type of container is generally divided into two types: one is that after the body is formed, the "bottle mouth" or "bottleneck" is combined with the body in the form of injection molding, and the material of the "bottle mouth" or "bottleneck" and the body Different, injection molding after filling cannot be realized

The main disadvantage of this manufacturing process is the high cost and complicated process caused by the injection molding process.

The injection molding process is added to the production of such containers, which is inefficient and time-consuming, has a draft angle, pollutes the environment, and also needs to clean up the residue generated by injection molding, which is prone to residues of injection molding odor; After the filling is completed, add a "bottle mouth" or "bottleneck" at the reserved through hole

For containers that require a sterile environment, before installing the "bottle mouth" or "bottleneck" at this time, the reserved through hole is polluted due to cooling water cooling, conveyor belt transmission, etc., and the "bottle mouth" or "bottleneck" is added There is no re-sterilization process, and chemical glue will be used when adding the "bottle mouth" or "bottleneck". When the user drinks, the aluminum foil at the reserved through hole will contact the contents of the container, and the contents will It will also come into contact with chemical glue, which can easily lead to secondary pollution, which will have a certain impact on the human body
