Abstract

PURPOSE:To prevent a baby from carelessly breaking a seal, to make it possible to break the seal easily when required, and to achieve excellent disposability by forming an inorganic oxide layer, as a seal breaking film, on a base film and providing a cut in the base film. CONSTITUTION:A formed sheet 1 and a seal breaking film 2 are provided, and the sheet 1 has a recess 3 for storing a solid item A such as chemicals. The film 2 is bonded to the sheet 1, excluding the recess 3, to seal the open end of the recess 3. As the formed sheet 1, a thermoplastic resin sheet is subjected to vacuum forming or press forming to form a recess 3 therein. For preparing the film 2, a metal oxide layer 22 is formed on the inner surface of a base film 21 by vapor deposition method and a cut (p) is formed through at least a portion of the base sheet 21 corresponding to the recess 3. Consequently, barrier characteristic equivalent to conventional aluminum foil is provided and protective property for contents is good and the solid item A can be taken out manually and simply, by pushing it with fingers.

2. Description of the Related Art In recent years, PTP packages have been commonly used for tablets, capsules and other chemicals. A thin plastic sheet is formed to form a recess for storing the chemical, and the recess is filled with the chemical. After that, the concave portion is sealed with an easily rupturable sealing film. As the sealing film, it is common to coat a resin for heat sealing on the back surface of an aluminum foil or the like, and by pressing with a finger from the recess side, the sealing film is broken to prevent chemicals or the like. You can take it out.

Since it is necessary to break the rupture film by pushing it with a finger from the recess side, a plastic film is not usually used for the rupture film. However, in order to prevent accidents caused by infants, etc. For this reason, one using a plastic film has been proposed. Broadly speaking, there are the following three types. (1) A plastic film is laminated on the outer side of an aluminum foil so that it can be easily peeled off.

The packaging body of the above (1) has a drawback that the convenience of PTP packaging is obviated because the plastic film must be peeled off before opening, and the packaging of the above (2). The body, while the uniaxially stretched film is easy to tear in the stretching direction, it is difficult to tear in the direction perpendicular to the stretching,
In the package containing the solid molded products such as tablets and capsules,
It may not be able to be opened sufficiently, and the package of (3) above can be easily opened because it is merely a thin and fragile plastic film stuck together, and it is possible to prevent accidents such as infants accidentally opening it. There is a problem that you cannot do it.
