[Industrial use]

The present invention relates to an improvement of a packaging container for contents which are particularly reluctant to be moisture in the form of powder and granules.

Conventional Technology and Its Challenges

Although it is a liquid packaging container, a box-type container of a box type and a box-shaped box of a plunge type top gable are known (see, for example, Japanese Patent Application Laid-Open No. 63-169415).

However, the exit of the brick box-shaped container is not suitable for packaging containers such as animal feed or fertilizer, such as powder or granular dog food, which are particularly reluctant due to the fact that it does not have a sewing function. The outlet of the rectangular top-gated box-shaped container has a sewing function because it has a plastic closure member, but there is a disadvantage that it is not suitable for lamination due to the fact that the closure member protrudes from the container body.

The purpose of the present invention is to prevent moisture absorption on the contents before opening, as well as after opening, to prevent the deterioration and alteration of the contents easily, and to be laminated, and to evenly distribute and prevent the alteration of the contents. In providing a packaging container.

[Means for solving the problem]

What is opened and sewn on the outer surface of the container body, the outer peripheral edge of the opening formed in the container body is detachably fixed (heat-sealed) to the sealing sheet, and the inner body of the container including the opening. The secondary sealing sheet having moisture resistance to the sheet (heat sealing), and the sealing sheet and the secondary sealing sheet facing the opening. Fixation (heat-sealing) with an adhesive strength condition greater than the breaking strength of the auxiliary sheet, the opening formed by a plurality of small hole groups, and a tamper-proof preventing means provided for the initial opening of the sealing sheet. And a slit for improving the contents in the vertical direction of an arbitrary side end of the container body.

[Action]

The peeling action of the sealing sheet is stopped at the fixed portion between the sealing sheet and the container body, the opening is opened correctly, and the sewing is also easy, and the moisture-proofing action on the contents is performed accurately.

Further, the fixing means of the narrow width outer surface portion of the outer peripheral edge of the opening enhances the moisture-proofing effect before opening, and further, by laying the auxiliary sealing sheet, the moisture-proofing effect before opening is further enhanced.

For example, the contents can be evenly spread by filling a pesticide such as home horticultural granules, granules, and gently shaking the container body by hand.

In addition, the contents can be sprayed while visually seeing the slit for measurement, and the lack of pesticide spraying can be accurately adjusted.

In addition, since the deterioration prevention means is provided in the sealing sheet, the filling replacement or weight failure of the contents can be reasonably prevented.
