Heterogenous-Substance Accommodating Device Having a Soft Folding Part

Abstract

A heterogeneous-substance accommodating device used by being coupled to a mouth of a container includes an accommodating part having a storage space disposed within a main body, a soft foldable part disposed on an upper portion of the accommodating part, and an opening part disposed on the bottom of the upper portion of the foldable part to lengthily extend downward. A different kind of substance is injected into the storage space of the accommodating part, and a lower portion of the accommodating part is sealed by using a sealing part. When the foldable part is pressed, the opening part breaks the sealing part so that the different kind of substance contained in the storage space drops into the container and is mixed. The foldable part is folded while being expanded outward when a force is applied to an upper portion of the foldable part.

         2 . The heterogeneous-substance accommodating device of  claim 1 , wherein, when the foldable part is expanded, the foldable part has a shape in which a foldable part upper portion folding reference surface that is an upper outer portion of the foldable part is wide, and a foldable part lower portion folding reference surface that is a lower outer portion of the foldable part is narrow. 
     
     
         3 . The heterogeneous-substance accommodating device of  claim 1 , wherein, when the foldable part is expanded, the foldable part forms an expanding reference surface having a large outer diameter between a foldable part upper portion folding reference surface that is an upper outer portion thereof and a foldable part lower portion folding reference surface that is a lower outer portion thereof. 
     
     
         4 . The heterogeneous-substance accommodating device of  claim 1 , wherein, when the foldable part is expanded, an upper portion of the foldable part is expanded and spread from a foldable part lower portion folding reference surface that is a lower end of the foldable part. 
     
     
         5 . A heterogeneous-substance accommodating device used by being coupled to a mouth of a container, comprising a soft foldable part, wherein an accommodating part having a storage space is disposed within a main body, the soft foldable part is disposed on an upper portion of the accommodating part, an opening part is disposed on the bottom of the upper portion of the foldable part to lengthily extend downward, a different kind of substance is injected into the storage space of the accommodating part, a lower portion of the accommodating part is sealed by using a sealing part, and when the foldable part is pressed, the opening part breaks the sealing part so that the different kind of substance contained in the storage space drops into the container and is mixed, characterized in that the foldable part has a shape in which a foldable part upper portion folding reference surface that is an upper outer portion of the foldable part is wide, and a foldable part lower portion folding reference surface that is a lower outer portion of the foldable part is narrow. 
     
     
         6 . The heterogeneous-substance accommodating device of  claim 5 , wherein, when the foldable part is folded, the foldable part is folded in a shape of which an upper portion is spread outward with respect to the lower outer portion. 
     
     
         7 . The heterogeneous-substance accommodating device of  claim 5 , wherein, when the foldable part is formed, a main body mouth is disposed on an upper portion of the main body, a foldable part adhesion surface that is expanded outward is disposed on an outer circumferential portion of a lower end of the main body mouth, and the soft foldable part is injection-molded to the foldable part adhesion surface. 
     
     
         8 . A heterogeneous-substance accommodating device used by being coupled to a mouth of a container, comprising a soft foldable part, wherein an accommodating part having a storage space is disposed within a main body, the soft foldable part is disposed on an upper portion of the accommodating part, an opening part is disposed on the bottom of the upper portion of the foldable part to lengthily extend downward, a different kind of substance is injected into the storage space of the accommodating part, a lower portion of the accommodating part is sealed by using a sealing part, when the foldable part is pressed, the opening part breaks the sealing part so that the different kind of substance contained in the storage space drops into the container and is mixed, and when a force is applied to an upper portion of the foldable part, the foldable part of the accommodating device is folded while being expanded outward, characterized in that a folding prevention part is disposed on an upper or lower portion of an upper end of the foldable part to prevent the foldable part from being further folded to a predetermined degree or more. 
     
     
         9 . The heterogeneous-substance accommodating device of  claim 8 , wherein the folding prevention part disposed on the foldable part comprises a folding prevention protrusion protruding upward or downward with respect to the upper portion of the foldable part. 
     
     
         10 . The heterogeneous-substance accommodating device of  claim 8 , wherein the folding prevention part disposed on the foldable part has a foldable part adhesion surface having an expanded shape on a portion at which an upper end of the foldable part meets the main body mouth of the main body.
