Abstract

PURPOSE:To make it easier to open paper containers for long term preservation by a method wherein at a part for opening when a packaging paper is formed into a container, a pull-out part for opening is attached on the packaging paper, and then the packaging paper is formed into a container. CONSTITUTION:At a spot which corresponds with an opening part 5 when a packaging paper 1 is formed and becomes a container 1', a pull-out part for opening 4 is attached on the packaging paper 1 at a stage where the packaging paper 1 is still in a sheet shape and is not yet formed into the container 1'. Under this condition, the packaging paper 1 is fed in a container manufacture unit 2, and the container 1' is formed. In this case, if the pull-out part for opening 4 is placed such as running across the packaging paper 1, pullout pieces are manufactured at both ends, i.., two pull-out pieces are manufactured, and if it is partially attached, one pull-out pieces are manufactured, and if it is partially attached, one pull-out piece is manufactured. The pull-out piece appears at the upper or lower end of the both edges bonded part of the packaging paper 1, however, it is possible to manufacture a pull-out piece at an optional spot by boring an appropriate spot on the packaging paper 1 and transferring one end of the pull-out part for opening 4 to the back side of the packaging paper 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Separation This invention relates to the production of paper packs with opening tools for facilitating the opening of paper packs for milk, fruit juice, etc., especially long-term storage paper containers. It is about the method.

Prior art There is no filling machine that has a mechanism for attaching opening strings, threads, pieces of cloth, pieces of film, etc. to paper packs.

Problems to be Solved by the Invention A method for producing a hygienic, quick, and simple container with an opening for paper packs such as milk or fruit juice.

Means for Solving the Problems A pull-out part 4 for opening is attached in advance to a position corresponding to the opening part 5 of the packaging paper 1 before being formed into paper packs, and the paper pack is introduced as it is into a forming apparatus for paper packs. A drawer part 4 for opening is simultaneously produced on the molded paper packs.

Operation: The packaging paper 1, to which the opening drawer part 4 is attached in advance at the position corresponding to the opening part 5, is introduced into the container manufacturing part 2, enters the container manufacturing part 2, is sealed by the sealing part 6, and becomes the container 1 for paper packs. Therefore, one or both ends of the opening drawer l1ls4 are shaped and manufactured as a drawer piece 4° outside the sealed container 1.

Embodiment Normally, paper packs for milk, fruit juice, etc. are automatically formed from packaging paper 1 having a polyethylene covering, which also serves as filling.

That is, the sheet-like packaging paper 1 is automatically transferred to the container manufacturing section 2.
After passing through processes such as side sealing, top sealing, content injection, and bottom sealing, 1! It is produced at a high speed of j seconds lv:1 or more.

However, in this process, there is no means to open the container, making it difficult to remove the contents such as milk and fruit juice.
It is as per the 4th knowledge.

In order to solve this drawback, the present invention is designed to form a sheet of packaging paper 1 at a location corresponding to the opening 111×5 when the packaging paper 1 is formed and the content 1' is formed as a container. Before this step, the unsealing drawer part 4 is attached to the wrapping paper 1, and in this state, it is sent to the container manufacturing part 2 and entered to form the container 1'.

At this time, when the opening drawer part 4 is made to cross the wrapping paper 1, the drawer piece 4 is made at both ends, that is, by evaporation, and when it is attached partially, a single piece is made.

The pull-out piece 4' appears at the upper end or the edge of the adhesive part on both sides of the wrapping paper 1, but a corresponding part of the wrapping paper 1 is perforated, one end of the opening pull-out part 4 is transferred to the back side, and the pull-out piece is placed at an arbitrary location. It is also possible to make a 4° angle.

Effects of the Invention The present invention creates a mechanism for easily opening paper pack containers for milk, fruit juice, etc. without changing the conventional manufacturing process at all. This is a useful invention that can be manufactured with high efficiency.

Claims (1)

[Claims] Packaging paper 1 for manufacturing containers for paper packs is transferred to container manufacturing part 2
Before entering the room, an opening tool is provided that attaches an opening drawer part 4 to the packaging paper 1 at the opening part 5 when the packaging paper 1 is formed into the container 1', and forms the packaging paper 1 into the container 1'. Method of manufacturing paper packs.
