A press-through pack comprising an accommodation main body (2) having a plurality of accommodation recesses (2a) connected with one another by a sheet-like portion (2b), a substrate (3), and a seal sheet (5) having an adhesive layer (4) disposed on one of the surfaces of the substrate (3), wherein the adhesive layer (4) of the seal sheet (5) and the sheet-like portion (2b) of the accommodation main body (2) are bonded under the state where a solid matter (T) is accommodated in each of a plurality of recesses (2a) of the accommodation main body (2), the accommodation main body (2) is sealed by the seal sheet (5), the seal sheet (5) is bonded to the sheet-like portion (2b) of the accommodation main body (2) so that the solid matter (T) can be taken out when a protuberance portion (2c) as the outer surface of the accommodation recess (2a) accommodating the solid matter is pushed by a finger and the portion of the seal sheet (5) sealing the accommodation recess (2a) is ruptured, without causing float and peel at the bond portion between the adhesive layer (4) of the seal sheet (5) and the sheet--like portion (2b) of the accommodation main body (2), and can be easily peeled off from the accommodation main body (2); and the seal sheet for this press-through pack.

L'invention concerne un emballage à expulsion par pression, comprenant un corps principal (2) doté d'une pluralité de cavités de logement (2a) maintenues en place par une partie du type feuille (2b), un substrat (3) et une feuille de scellage (5) à couche adhésive (4) disposée sur l'une des surfaces du substrat (3). La couche adhésive (4) de la feuille de scellage (5) et la partie du type feuille (2b) du corps principal (2) sont rattachées l'une à l'autre dans les conditions suivantes : une matière solide (T) est placée dans chacune des cavités de logement (2a) du corps principal (2), lequel est scellé par la feuille de scellage (5), elle-même liée à la partie du type feuille (2b) du corps principal (2), de manière à expulser la matière solide (T) par pression du doigt sur une section protubérante (2c) tenant lieu de surface extérieure pour lesdites cavités (2a) dans lesquelles sont logées les éléments de matière solide. Cette pression a pour effet de rompre la feuille de scellage (5) scellant les cavités de logement respectives (2a), sans engendrer de flottement et d'effeuillage de la partie de liaison entre la couche adhésive (4) de la feuille de scellage (5) et la partie du type feuille (2b) du corps principal (2), ce qui donne un arrachage facile depuis ledit corps (2). L'invention concerne également une feuille de scellage pour l'emballage considéré.
