Blister pack

Abstract

[Problems to be Solved] To provide a blister pack which can be easily torn off and peeled by automatically adjusting a position of tearing off and peeling even if a seal member becomes diagonally with respect to a longitudinal direction of a main body portion (storage recess portion) of the blister pack. [Solution] The blister pack includes a main body portion 1 and seal member 2. The main body portion 1 includes a rectangular storage recess portion ( 1 a ) recessed at a center thereof and a plane portion for seal member adhesion ( 1 b ) provided around the storage recess portion ( 1 a ). The plane portion for seal member adhesion ( 1 ) is formed in a direction parallel with the longitudinal direction of the storage recess portion ( 1 a ), and on the right and left sides. The seal member ( 2 ) has a gripping part ( 2 a ) protruding at least one end in the longitudinal direction of the main body portion ( 1 ). The seal member ( 2 ) seals a content adhered to the plane portion for seal member adhesion ( 2 b ) and stored in the storage recess portion ( 1 a ), and is torn off and peeled from the gripping part ( 2 a ). The one end of the main body portion ( 1 ) is protruded to be a convex shape having an apex toward the side opposite to the storage recess portion, and formed to be line symmetry with respect to a center axis in a direction parallel with the longitudinal direction of the storage recess portion ( 1 a ).

What is claimed is;: 
     
         1 . A blister pack comprising a main body portion ( 1 ) and a seal member ( 2 ),
 wherein the main body portion ( 1 ) comprises a rectangular storage recess portion ( 1   a ) recessed at a center thereof, and a seal member adhering plane portion ( 1   b ) provided around the storage recess portion ( 1   a ),   wherein the seal member adhering plane portion ( 1   b ) is formed in a direction parallel with the longitudinal direction of the storage recess portion ( 1   a ), and on the right and left sides of the longitudinal direction,   wherein the seal member ( 2 ) has a gripping part ( 2   a ) extending beyond at least one end in the longitudinal direction of the main body portion ( 1 ),   wherein the seal member ( 2 ) is to be adhered to the seal member adhering plane portion ( 1   b ) to thereby seal a stored item in the storage recess portion ( 1   a ), and is to be torn off and peeled from the gripping part ( 2   a ), and   wherein one end of the main body portion ( 1 ) is protruded to be a convex shape having an apex toward the side opposite to the storage recess portion ( 1   a ), and is formed to be line symmetry with respect to a center line in a direction parallel with the longitudinal direction of the storage recess portion ( 1   a ).   
     
     
         2 . The blister pack according to  claim 1 ,
