Description

Infusion container manufacturing apparatus {Apparatus for manufacturing infusion container}

The present invention relates to an apparatus for manufacturing an infusion container.

The infusion container includes a body and a port disposed on the body. The body may be made of a flexible material. The inside of the body is filled with sap. The sap is injected into the body through the port or discharged to the outside.

The infusion container manufacturing apparatus can be largely divided into an apparatus for manufacturing a body by overlapping sheets and sealing, and an apparatus for mounting and sealing a port on the manufactured body.

Republic of Korea Patent Registration No. 10-2022070 (2019.09.18. Announcement, hereinafter referred to as this document) discloses an apparatus for manufacturing an infusion container.

In the case of this document, two sheets each wound on a take-up roll are overlapped, and the outer edges of the sheets are sealed to form a body.

In the process of forming the body by sealing the sheet in this way, the sheet may be pre-cut. A portion of the pre-cut sheet is later discarded as scrap. The amount of scrap to be discarded may vary greatly depending on the type of pre-cutting the sheet. Therefore, in order to reduce the manufacturing cost and manufacturing time, there is a need for an apparatus for manufacturing an infusion container that can easily remove sheet scraps and facilitate cutting.
