Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to tablets and capsules,
More specifically, the blister package used for packaging other items to be packaged can accurately and easily take out a predetermined number of items to be packaged by opening only the accommodating portion taken out at one time, and furthermore, tablets, It can be applied not only to capsules, but also to packages such as granules, jellies, and liquids, and packages that are fragile such as disintegrating tablets. About.

[0002]

BACKGROUND OF THE INVENTION Packaging of solid preparations such as tablets and capsules involves
A plurality of convex portions are formed on a plastic molded sheet, a solid agent is stored in a housing portion in the convex portion, sealed with a seal sheet, and when taken, the convex portion is pressed to push the seal sheet with the solid agent. There is a so-called PTP-type blister package that is torn and taken out. This blister package of the PTP type has the advantages that the solid agent is individually packaged, easy to count, compact and easy to store, and relatively easy to take out. Because of this, it is frequently used for packaging solid preparations.

[0003] Since the above-mentioned blister packages are generally packaged with one kind of solid agent arranged side by side, when taking a plurality or a plurality of types of solid agents at one time, it is necessary to take out the required number from each blister package. There is a risk that the quantity taken may be excessive or deficient. To prevent this, 1
The dose may be prepared by cutting the blister package in advance from each blister package. .

[0004]

2. Description of the Related Art As a blister package that solves these drawbacks, there is a conventional blister package in which solid agents are arranged in a line for each single dose as disclosed in, for example, Japanese Patent Application Laid-Open No. 7-267284. . For example, as shown in FIG. 4, a solid agent (5) such as a tablet (53) or capsule (54) of the same type is
2) A blister package (50) containing a plurality of solid agents (52) to be taken at one time in the lateral direction.
When taking, only one dose is taken out, for example, by cutting one row in the horizontal direction with a sewing machine line (55).

[0005]

The conventional PTP-type blister package (50) can relatively easily take out the solid agent (52) only by pressing the convex portion (51) as described above. There is a possibility that the portion other than the portion to be taken at one time is easily opened by mistake, resulting in an excess or deficiency in the dose.

[0006] Further, in the blister package of the PTP type, although the take-out operation is relatively simple, the solid agent must be extruded by pressing the convex portions one by one. The operation is complicated and cannot be applied to the packaging of disintegrating tablets and the like, which are easily destroyed by the application of force.In addition, tablets, capsules, as well as granules, jellies, and liquids, are not packaged. There is a problem that it cannot be applied to these packages because it cannot be easily taken out even if the convex portion is pressed.

[0007] The present invention solves the above-mentioned problems, and it is possible to accurately and easily take out a predetermined number of items to be packaged by opening only the accommodating portion taken out at one time. That is, it is possible to provide a package that can be applied to packages such as granules, jellies and liquids, and packages that are fragile such as disintegrating tablets, and that there is no danger of swallowing the entire package by mistake. Technical issues.

[0008]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention will be described with reference to FIGS. 1 to 3 showing an embodiment of the present invention. . That is, a molded sheet formed with a plurality of convex portions (2)
A sealing sheet (5) is adhered to (4) to individually seal the accommodating portions (3) in each projection (2), and a slit (6) is provided in the sealing sheet (5). ), The sealing sheet (5) is divided into an opening portion (7) covering the entire accommodating portion (3) taken out at one time, and the sealing sheet in the opening portion (7) is divided.
(5) The breaking strength of the seal sheet (5) and the molded sheet (4)
Is set to be higher than the adhesive strength of the opening portion, a grip portion (8) is provided at the edge of the opening portion (7), and the opening portion (7) is pulled by pulling the grip portion (8) to form the molding sheet (4). Characterized in that it is configured to be peelable from the device.

[0009]

Before the opening portion is opened, such as during storage, the blister package is not of the so-called PTP type and the break strength of the seal sheet is set high. Also, the seal sheet cannot be crushed, and there is no fear that the packaged material is accidentally taken out.

When the packaged object is taken out of the blister package, by pulling the grip portion, the seal sheet is broken by a slit provided around the opening portion and the opening portion is peeled off. Thereby, all of the accommodating parts taken out at one time are opened, and only the necessary number of items to be packaged are taken out without pressing the convex parts.

The slit defined in the opening portion may be any configuration as long as the seal sheet can be broken at the opening portion as described above. For example, a slit that penetrates only the seal sheet and does not penetrate the molded sheet, The seal sheet may be formed in a groove shape with a small amount left, and may be constituted by a slit having a structure in which the remaining portion is broken when the opening portion is peeled off.

When the inner surface of the unsealing portion and the molded sheet are adhered with a re-adhesive adhesive, the opened seal sheet is pressed against the molded sheet so as to leave a part of the article to be packaged. The part is sealed again.
