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...

Benefits of technology

[0019] In the container, the opposite seal sheets comprise the joined portions that are joined onto the corresponding inner surfaces of the opposite wall regions forming the communicating section, along the entire width of the communicating section, and the sealing portions extending from the joined portions toward the storage section in the unjoined conditions relative to the opposite wall regions, and the at least parts of the sealing portions are opposite each other so as to be adherable to each other and separable from each other substantially over the entire width of the communicating section, so that by tearing opposite wall regions of the container wall, which form the opening, to thereby form the opening, and causing the opposite wall regions forming the opening to be separated from each other substantially over the entire width of the openable section, to thereby cause the opposite wall regions forming the communicating section to be broadly separated from each other, the opposite seal sheets can be separated from each other according to broadening of the communicating section. Therefore, by merely causing the opening to be widely broadened at the time of the use of the container, the communicating section can be widely broadened and the seal sheets can be widely separated from each other. It is possible to easily pour a dilute liquid or the like into the storage section through the widely opened opening.

[0020] Furthermore, by causing the opposite wall regions forming the communicating section to approach each other after the dilute liquid or the like is poured into the storage section, the sealing portions of the opposite seal sheets can be moved nearer to each other and adhere to each other over the entire width of the communicating section, whereby a side of the storage section that is adjacent to the openable section is re-closed by the seal sheets. Therefore, any contaminant such as dirt and/or dust hardly enters the storage section through the opening. Also, even if the upper surface of the contents is changed after the forming of th

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, t
