[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a squeezing structure of a packaging bag containing a viscous or contaminated fluid, and more specifically, a curing agent used for a two-pack type sealing material or a viscous or contaminated fluid such as instant foods. The present invention relates to a squeezing structure for a packaging bag, which includes a packaging bag that encloses the packaging bag and squeezing means that efficiently squeezes the contents from the packaging bag.

[0002]

[Prior art]

 Conventionally, plastic packs have been the mainstream packaging bag for hardeners used for two-component type sealing agents, etc., and a specified amount of the hardener that is balanced with the amount of the main material is put in the plastic pack as an auxiliary material. It is attached as a set to the main material product that has been stored in the container in advance.

[0003]

[Problems to be solved by the device]

 Then, at the beginning of using the two-component sealing agent, when injecting the curing agent into the main material, in order to squeeze out a specified amount of the content in the pack, for example, the opening part is cut off and extracted, and then the acupressure is applied. Therefore, it was squeezed from the back end side of the fill pack by strongly crimping.

However, in reality, the residue in the fill pack cannot be completely extracted only by the above-mentioned operation, so that it is necessary to handle it with the can edge or rub it against the wall of the can. However, there is a problem that workability and work efficiency are extremely poor. In particular, since the curing agent, etc. uses active chemicals, it may adhere to the fingers, etc. during the work of removing the residue, and in this case, there is a problem that work such as cleaning is indispensable for allergy prevention. It was

In recent years, pack products have increased in relation to foods, and for example, pack products such as instant curry, natto and Chinese products, and pack accessories such as seasonings are on the market. However, it was difficult to extract the contents of the pack without leaving any residue after opening the seal before meals, and there were problems such as soiling the hands and the table.

The present invention has been devised in view of such conventional problems, and extracts the contents sealed in the packaging bag surely without leaving a residue and without contaminating fingers or the like. It is an object of the present invention to provide a squeezing structure of a packaging bag in which a viscous or contaminated fluid that can be filled is enclosed.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a packaging bag main body made of a flexible material, which encloses the contents and has an opening portion at one end, and a slit which is inserted from the other end side of the packaging bag main body. The gist of the present invention is that it comprises squeezing means for squeezing out the contents by pulling from the other end side of the unsealing part.

Further, according to the present invention, a content take-out opening section is provided in the center of one side of a packaging bag body made of a flexible material in which the content is enclosed, and the content is opened at the upper and lower surfaces of the take-out opening section. The gist of the present invention is to provide a protective portion for preventing the adhesion of the contents when squeezing out.

[0009]

[Function of the device]

 This invention is configured as described above, and when the contents are taken out from the packaging bag body, first, the opening portion on one end side of the packaging bag body is cut off, and the other end side of the packaging bag body is formed into the slit of the squeezing means. By inserting and pulling the contents, the contents are squeezed by the squeezing means and sequentially pushed out, and at the same time, the contents can flow out from the cut open portion and be surely extracted.

In addition, on one side of the body of the packaging bag, a portion for taking out and opening the contents is provided in the central portion, and a protective portion for preventing adhesion of the contents is provided at the upper and lower surfaces of the taking and opening portion of the body of the packaging bag. In this case, the content of the unsealed part should be removed when the unsealed part at the center is cut out and pushed out from the rear end side while crimping with finger pressure, or when squeezed out by the squeezing means equipped with the slit as described above. It is possible to reliably extract without sticking to the surroundings of the hands or the hands.
