Openable and re-closable container and method for making the container having contents stored therein

Abstract

A storage section 18, a communicating section 22, an openable section 20, and a discharged section are provided. Regions of container walls 12a (12b) that form an opening 21 to be formed by tearing the openable section 20 are approchable each other, and regions of the container walls 12a (12b) that form the communicating section 22 are approchable each other. When the regions of the container walls 12a (12b) that form the opening 21 are separated from each other over the entire width thereof, the regions of the container walls 12a (12b) that form the communicating section 22 can be separated from each other. Seal sheets 28a (28b) are respectively joined to the regions of the container walls 12a (12b) that form the communicating section 22. The seal sheets 28a (28b) are opposite each other and extend toward the storage section 18. The seal sheets 28a (28b) include sealing portions 32 that adhere to each other in a condition where they are separatable from each other over the entire width of the communicating section 18 from joined positions 30 thereof to storage section 18. When the sealing portions 32 of the seal sheets 28a (28b) are separated from each other and re-adhere to each other, the opening 21 can be re-closed.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a container that is freely openable and re-closable, and a method for making a freely openable and re-closable container having contents preliminarily stored therein. [0003] 2. Description of the Prior Art [0004] Hitherto, as a container for storing an enteral nutrient, an inspissated liquid diet or the like, there was employed a container made of resin and having a storage section, an openable section disposed above the storage section and communicating with the storage section, and a discharged section provided at a lower part of the container. [0005] The conventional container is hermetically sealed in a condition where an enteral nutrient or an inspissated liquid diet is preliminarily stored within the storage section. The use of the container is carried out by tearing portions of container walls that form the openable section, to thereby form an opening, pouring a dilute liquid into th...

AI Technical Summary

Benefits of technology

[0015] It is therefore an object of the present invention to provide an openable and re-closable container in which, at the time of the use of the container, an opening of the container can be widely broadened and easily re-closed, and which can be easily produced.

[0064] In the method, the putting of the contents into the storage section is carried out in the protected condition where the opposite surfaces of the sealing portions do not contact the contents, so that the contents hardly flow between the sealing portions of the seal sheets at the time of putting of the contents into the storage section, and hardly attach to the opposite surfaces of the sealing portions and inner surfaces of the openable section. Also, when the person performs the broadening of the opening after the opening is formed by tearing the portion of the container wall, the person can sanitarily handle the container without touching the contents.

Problems solved by technology

This takes a lot of labor.

Particularly, when a lot of containers are required to be prepared in a hospital or the like, the fitting of the elongated mating chuck seals together is considerably troublesome.

Furthermore, in a home medical treatment, it is significantly hard for a patient whose eyesight fails and / or a patient whose body is disabled, to cause the elongated mating chuck seals to be completely fitted together.

If the mating chuck seals are incompletely fitted together and parts of the chuck seals remain disengaged from each other, the contents within the container will leak out of the container through the parts of the mating chuck seals that are not fitted together.

Moreover, there is a possibility that the separation of the mating chuck seals will start from the disengaged parts of the mating chuck seals, whereby the chuck seals will be easily disengaged from each other, and the contents within the container will spill out of the container.

Therefore, it is hard to cause the chuck seals to be joined to the tightly shut peripheral portion of the container walls in such a manner that the chuck seals extend continuously from the tightly shut peripheral portion of the container walls, without producing any clearance between the chuck seals and the tightly shut peripheral portion of the container walls.

Therefore, the preparing of the container takes a lot of labor.
