Description

The present invention relates to the shape of a press-through package (PTP) that stores drugs such as tablets and capsules. More specifically, the present invention relates to a press-through package that facilitates the collapse or crushing of the bulge storage portion when the bulge storage portion storing the tablets is pressed, and improves the easy-openability of the lid.

  As shown in FIGS. 3 and 4, a conventional medicinal press-through package has a rigid sheet-like molded body (main body) such as a vinyl chloride sheet having a thickness of about 300 μm, and a lid made of an aluminum foil having a thickness of about 20 μm. Or the thing of the structure which consists of the cover material of the laminated resin film which made the film about several tens of micrometers thick into the multilayer is widely used. To take out the stored item (tablet), a method is adopted in which the swelled portion is pressed and crushed and the stored item is pushed through the swelled storing unit so that the lid material is pushed open by the stored item and opened.

As a press-through package with improved easy-openability of the lid material, for example, according to Japanese Patent Application Laid-Open No. 2002-225930, a sheet-like molded body is provided with a large number of bulge portions that are formed by thermoforming and projecting to the surface side. Using a laminated film made of a synthetic resin material so as to close the opening of the recessed portion on the back surface of the sheet-shaped molded body with a non-contained item in the concave portion inside the section, this laminated film is smaller than the sheet-shaped molded body. Joined so as to be peelable by the bonding force, and formed a notch so as to penetrate the laminated film in the thickness direction from the back side of the laminated film at a position surrounding the opening of each concave portion, but not to penetrate the sheet-like molded body in the thickness direction. There has been proposed a package characterized in that
JP 2002-225930 A

However, the press-through package in Patent Document 1 improves the easy-openability of the lid material by providing a cut in the lid material, and does not refer to the bulge storage part of the main body.
Furthermore, the process of providing a cut in the cover material increases and the cost is high, and the moisture resistance may be impaired due to variations in the cut depth.

The present invention facilitates deformation and crushing of the bulge storage part when the bulge storage part is finger pressed with a thumb nail or the like, and improves easy-openability by breaking the lid material via the tablet in the bulge storage part. Objective. It is another object of the present invention to allow the tablet to be pushed out by sandwiching the storage portion with the thumb and the index finger.

A press-through package according to the present invention comprises a main body provided with a plurality of bulge storage portions for storing tablets at a predetermined interval, and a lid member for sealing the bulge storage portion, and the tablet is broken by breaking the lid material. A package of a form to be taken out, characterized in that the shape of the bulge storage part is a truncated pyramid shape with an open bottom, so that when the top of the bulge storage part is acupressureed, a cylindrical surface as in the past The top part of the spherical surface that is supported on the top of the spherical surface can be easily deformed and crushed from the top as compared with the press-through structure, and the easy opening of the lid can be improved through the tablet. Also, when the pyramid surface of the bulge storage portion is acupressureed, the pyramid surface can be easily tilted as compared with a conventional cylindrical surface or a tapered cylindrical surface. Furthermore, the tablet can be easily pushed out by sandwiching the opposing pyramid surfaces between the thumb and the index finger.

Furthermore, the press-through package according to the present invention is characterized in that, in the above description, the bottom of the opening is replaced with a rectangle, and the opening is circular, so that the bonding area between the main body and the lid is compared with the rectangle. Increase. Moreover, the depression shape of the pressing mold for thermocompression bonding around the bulge storage portion becomes circular, and the processing of the pressing mold becomes easy.

Furthermore, the press-through package according to the present invention is characterized in that, in the above description, the top portion is replaced with a flat surface and is a part of a spherical surface. Even if it piles up more than one, it does not bulk.

With the above configuration, the press-through package of the present invention has a top portion that is supported on a cylindrical surface as in the prior art and that forms a part of a spherical surface from the top when compared with a press-through configuration when the top of the bulge storage portion is finger pressed. This facilitates the deformation and crushing of the lid and improves the ease of opening of the lid material via the tablet. Moreover, when any one of the pyramidal surfaces of the bulge storage part is acupressure, the pyramid surface can be easily tilted as compared to pressing a conventional cylindrical surface or a tapered cylindrical surface. Furthermore, the tablet can be easily pushed out by sandwiching the opposing pyramid surfaces between the thumb and the index finger. As a result, children with weak fingers and the elderly can easily open the press-through package. The present invention is particularly effective when the tablet diameter is as small as about 5 mm.

The press-through package according to the present invention is as described above. The sheet-like molded body (main body) constituting the press-through package is preferably constituted by a transparent resin sheet having a rigidity of about 200 to 300 μm. As the transparent resin sheet, any general resin member such as vinyl chloride sheet, polypropylene (PP), polyethylene terephthalate (PET), polyethylene (PE), etc. may be used.
It is preferable that the bulge storage portion for storing the tablet is disposed by vacuum molding or pressure molding of the main body resin. The resin thickness of the bulge storage part is preferably about 70 to 100 μm.

The lid is made of about 20 μm aluminum foil, about 10 μm thick aluminum foil, about 100 μm thick paper, about 40 to 70 μm thick synthetic resin film, different types of resin films such as about 12 μm PET film and about 30 μm thick. It is preferable to use one selected from a resin sheet in which PE films are laminated, a resin film in which aluminum is deposited by about 1000 mm, such as a PET film having a thickness of about 20 μm.

  It is obvious that the pyramid shape may be any shape such as a triangular frustum and a quadrangular frustum. In addition, the inclination angle θ of the pyramid surface may be arbitrary, but is preferably set in a range of 40 degrees to 60 degrees.

Hereinafter, the press-through package of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a press-through package according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of a main part of FIG. 1 cut along cutting lines S1 to S1.

A press-through package 100 shown in FIGS. 1 and 2 includes a sheet-like molded body (main body) 10 provided with a plurality of bulge storage portions 20 for storing tablets 4 at predetermined intervals, and a lid member for sealing the bulge storage portions 20. 6 is a package in which the lid member 6 is broken and the tablet 4 is taken out, and the shape of the bulge storage portion 20 is a quadrangular frustum shape having an open bottom. When the tablet 4 to be stored had a diameter of 5 mm and a thickness of 3.5 mm, the side of the open bottom of the square frustum was about 6 mm and the height of the square frustum was about 4.5 mm. The inclination angle of the pyramid surface 21 constituting the quadrangular pyramid was about 60 degrees.

The sheet-like molded body 10 is made of a transparent synthetic resin material such as polypropylene. Ten bulge storage portions 20 having a thickness of about 90 μm are formed on the surface side by vacuum forming in two rows and five columns at predetermined intervals. The flat part other than the bulge storage part 20 is a sheet-like molded body having a thickness of about 200 μm. In the state where the tablet 4 having a circular outer periphery is put in the concave portion 30 inside each bulge storage portion 20 of the sheet-shaped molded body 10, the entire back surface of the sheet-shaped molded body 10 is closed so as to close the opening 50 of the concave portion 30. A synthetic resin laminated film 6 is attached by heat sealing.

The laminated film 6 is a transparent vapor-deposited polyethylene terephthalate film layer 6a having a thickness of about 8 μm, and a transparent ethylene acetic acid film having a thickness of about 10 μm bonded to the film layer 6a by a dry lamination with a large bonding strength of 2.0 N / cm or more. The film layer 6b is made of a blend material of a vinyl copolymer resin and an olefin resin.
The laminated film 6 is stacked on the sheet-like molded body 10 so that the film layer 6b faces the back side of the sheet-like molded body 10, and the heat-sealed surface is attached by heat sealing so that the interface can be peeled off.

Specifically, the film layer 6b and the sheet-like molded body 10 are bonded with a small bonding force of about 1.0 N / cm to 13.0 N / cm. The reason why the laminated film 6 is provided with the transparent vapor-deposited polyethylene terephthalate film layer 6a is to obtain an effect of preventing moisture from entering the recess 30 and a gas barrier effect.
Since the sheet-like molded body 10 is made of polypropylene and has a large thickness, the effect of preventing moisture from entering the recess 30 is exhibited. In addition, when gas barrier property is required for the sheet-like molded body 10, it is obvious that a film layer made of a material having a gas barrier effect may be provided.

In order to take out the tablet 4 from the concave portion 30 of the package body having the above-described configuration, as shown in FIG. 2, finger pressure is applied from above to the top of the bulge storage portion 20 on the surface side of the sheet-like molded body 10. Alternatively, acupressure is applied to depress the quadrangular pyramid surface 21. A bending moment with the opening edge 70 of the housing portion as a fulcrum acts on the top or side wall due to the finger pressure. The tablet 4 in the recess 30 is swelled and pressed against the laminated film 6 side through the storage portion 20, and the laminated film 6 covering the opening 50 of the sheet-like molded body 10 is broken along the opening edge 70 by the force. Peel off. As a result, the opening 50 is opened and the tablet 4 can be taken out from the recess 30.

It is obvious that the bottom surface opened in the above embodiment may be a circular shape instead of a rectangle. Similarly, the top 23 may be a part of a spherical surface instead of a flat surface.

The press-through package of the present invention can be used not only for drugs such as tablets and capsules but also for storing granules or liquid drugs.
