Packaging case for disposable compressed tissue and manufacturing method thereof

Abstract

A packaging case for disposable compressed tissues is provided, which includes: a first accommodation portion which accommodates liquid; a second accommodation portion which has a stepped portion on the upper portion of the first accommodation portion so that the cross-sectional area of the second accommodation portion is larger than that of the first accommodation portion, and is partitioned from the first accommodation portion by a separable film which is thermally fused on the stepped portion by a thermal fusion operation, to thus accommodate tissues which have been compressed and dried; and a cover film which covers the upper portion of the second accommodation portion, wherein a bursting strength of the cover film is larger than that of the separable film when pressurized, so that the separable film is bursted before the cover film is bursted when pressurized.

1 . A packaging case for disposable compressed tissues, comprising:
 a first accommodation portion which accommodates liquid;   a second accommodation portion which has a stepped portion on the upper portion of the first accommodation portion so that the cross-sectional area of the second accommodation portion is larger than that of the first accommodation portion, and is partitioned from the first accommodation portion by a separable film which is thermally fused on the stepped portion by a thermal fusion operation, to thus accommodate tissues which have been compressed and dried; and   a cover film which covers the upper portion of the second accommodation portion, wherein a bursting strength of the cover film is larger than that of the separable film when pressurized, so that the separable film is bursted before the cover film is bursted when pressurized.   
   
   
       2 . The packaging case for disposable compressed tissues according to  claim 1 , wherein the separable film is a metal thin film, and the cover film is a metal thin film on which synthetic resin has been coated. 
   
   
       3 . A method of manufacturing a packaging case for disposable compressed tissues, comprising the steps of:
 molding a synthetic resin material to form a first accommodation portion which accommodates liquid, a second accommodation portion which has a stepped portion on the upper portion of the first accommodation portion to thus accommodate tissues which have been compressed and dried;   thermally fusing a separable film on the stepped portion after having accommodated liquid in the first accommodation portion; and   covering the upper portion of the second accommodation portion after having accommodated tissues in the second accommodation portion which have been compressed and dried, wherein a bursting strength of the cover film is larger than that of the separable film when pressurized, so that the separable film is bursted before the cover film is bursted when pressurized.   
   
   
       4 . The method of manufacturing a packaging case for disposable compressed tissues of  claim 3 , wherein the separable film is safely situated on the stepped portion by vacuum adsorption of a vacuum adsorption device and then thermally fused thereon by a thermal fusion device combined with the vacuum adsorption device.
