Description

  The present invention relates to a press-through pack package (PTP package) that accommodates articles such as tablets and capsules.

  Conventionally, a package called a PTP package has been used as a package for drugs such as pharmaceutical tablets, supplements, foods and the like. In general, a PTP package is arranged on a sheet-like base material having a concave accommodating part capable of accommodating an object to be accommodated, and on a surface side of the base part that is open to the accommodating part. And a lid member that closes the opening of the housing portion. In order to take out the object from such a PTP package, the container is pushed from the outside to be deformed. As a result, the object to be accommodated breaks through the lid member, and the object to be accommodated is taken out.

  However, the conventional package has a problem that when the container is taken out, it is necessary to push out the containing part by pushing the containing part with a finger or the like, and the taking out operation is complicated. In particular, there are cases where it is difficult for an elderly person or the like who has a weak finger strength to push the storage part so strongly that the object to be stored breaks through the lid. Therefore, there is a demand for a PTP package that can more easily remove an object to be contained.

  As a PTP package for easily removing an object to be stored, for example, Patent Document 1 discloses a PTP package in which a concave groove is formed that crosses the vicinity of the center of the top surface of the storage unit. According to such a PTP package, when one end of the side corner portion is sandwiched with one hand and the other end side is pressed against the desk, the storage portion is bent into a substantially square shape along the concave groove. The concave groove of the surface portion comes into contact with the object to be stored and pushes it toward the cover material, and the object to be stored breaks through the cover material and is taken out by the pressure. Thus, since the PTP package can be opened with one hand, it is possible to take out the object to be contained relatively easily.

  However, in the PTP packaging body of the patent document, since the concave groove pushes the container from the position where the concave groove comes into contact with the container when opened, the contact position is shifted from the center of the container. May end up. In that case, there is a problem that the force from the concave groove is not effectively transmitted to the lid material directly under the object to be stored and cannot be easily opened.

  This invention makes it a subject to provide the PTP package which can take out a to-be-contained object easily in view of said problem.

  The PTP package according to the present invention has a sheet-like base having an opening on one side and containing an object to be accommodated therein, and a flange extending from the periphery of the opening of the accommodation part. And a sheet-like lid member that closes the opening of the housing portion by being bonded to the one surface side of the flange portion, wherein the housing portion is bent. Thus, a plurality of ridges are provided in which the surface of the accommodating portion is raised in a convex shape so that the accommodating portion can be contracted and deformed in a bellows shape.

According to such a configuration, when the PTP package is folded in half and opened, the housing portion can be easily deformed in a bellows shape. At this time, the volume inside the housing portion becomes smaller as the housing portion shrinks and deforms. Then, when the internal volume of the accommodating portion is reduced to such an extent that the accommodating object cannot be accommodated, the accommodating object is pressed from the inner wall of the accommodating portion, breaks through the lid member, and is discharged from the accommodating portion.
As described above, according to such a PTP package, it is possible to easily take out the object by bending the PTP package.

  Moreover, in the PTP package according to the present invention, preferably, a bending line for facilitating the bending may be formed on the flange portion. According to such a configuration, the PTP package can be easily folded in two at the time of opening.

  Furthermore, in the PTP package according to the present invention, preferably, a cover body that covers the flange portion may be provided. According to such a configuration, the flange portion can be reinforced by the cover body, and information such as a cautionary note about the contents to be contained in the cover body, a method for opening the package, and an advertisement is described. Can do.

  In the PTP package according to the present invention, preferably, the cover body may be provided with a cover bending guide portion for facilitating the bending. According to such a configuration, the cover body can be easily bent along the cover bending guide part, and thereby the object to be accommodated can be taken out more easily.

  The PTP package 1 includes a sheet-like lid member 20 that closes the opening 18 of the housing portion 11 by being bonded to the flange portion 15 of the base material 10 from below. Specifically, the lid member 20 is bonded to the flange portion 15 extending from the periphery of the opening 18 so as to cover the opening 18 of the housing portion 11.

The lid member 20 is configured to be pierced by the object C to be contained. For example, the lid member 20 may be strong enough to be pierced by the object to be contained C. In addition, the lid member 20 may have a perforation or the like formed around the position where the object C breaks through the lid member 20.
The material and thickness of the lid member 20 can be appropriately set according to the type of the object C to be stored. Examples of the material of the lid member 20 include aluminum foil, glassine paper, a synthetic resin film, or a laminate thereof. The thickness of the lid member 20 may preferably be in the range of 17 to 60 μm.

The flange portion 15 of the substrate 10 and the lid member 20 may be bonded by any method. For example, the flange portion 15 and the lid member 20 may be bonded via an adhesive.
Moreover, when the flange part 15 and the cover material 20 are the materials which can be heat-sealed, the flange part 15 and the cover material 20 may be adhere | attached by the heat seal. In that case, it is preferable that the material of the flange part and the cover material 20 contains the same kind of thermoplastic resin material.

  Next, an example of a method for manufacturing the PTP package 1 will be described.

First, the accommodating part 11 is formed in the sheet-like base material 10. At this time, the portion of the base material 10 where the accommodating portion 11 is not formed becomes the flange portion 15 of the base material 10.
The method for forming the accommodating portion 11 is not particularly limited. The accommodating part 11 may be formed by pressing the metal mold | die in which the shape corresponding to the some protruding item | line part 12 was formed in the concave surface to a part of base material 10, for example. As a means for pressing the substrate 10 against the mold, the portion of the substrate 10 may be evacuated to the mold, and compressed air is applied to the portion of the substrate 10 toward the mold. You may go by spraying.
Moreover, you may form the some protruding item | line part 12 in the said part, after pressing on the metal mold | die whose concave surface is not processed especially in the said part of the base material 10. FIG.

Next, the object C is accommodated in the accommodating portion 11. Thereafter, the lid member 20 is bonded to the flange portion 15 of the base material 10. Thereby, the accommodating part 11 is block | closed in the state in which the to-be-contained object C was accommodated.
The flange portion 15 of the substrate 10 and the lid member 20 may be bonded by any method. For example, the flange portion 15 and the lid member 20 may be bonded via an adhesive or may be bonded by heat sealing.

  Next, an example of a method for taking out the object C from the PTP package 1 will be described with reference to FIG.

  In order to take out the object C from the PTP package 1, the PTP package 1 is placed so that the accommodating portion 11 is inside along the direction in which the protruding strip portion 12 of the accommodating portion 11 extends (that is, the lid member 20. Fold it in half so that it is on the outside. In the present embodiment, since the folding line 16 is formed along the direction in which the ridges 12 of the accommodating portion 11 extend, the folding line 16 can be easily folded in two along the bending line 16.

  As described above, when the PTP package 1 is folded in half, the accommodating portion 11 receives a force for bending the PTP package 1 and deforms. At this time, the accommodating portion 11 can be easily contracted and deformed into a bellows shape as shown in FIG. Thus, since the force required for deforming the accommodating portion 11 is small, the PTP package 1 can be folded in two with a smaller force.

  And as the accommodating part 11 shrinks and deforms by bending the PTP package 1, the internal volume of the accommodating part 11 becomes smaller. When the internal volume of the storage portion 11 is reduced to such an extent that the storage object C cannot be stored, the storage object C is squeezed from the inner wall of the storage portion 11 and breaks through the lid member 20 that has closed the storage portion 11. It is discharged from the storage unit 11. Thus, the to-be-contained object C can be easily taken out from the PTP package 1 of the present embodiment.

Further, when the PTP package 1 is bent, a part of the lid member 20 that covers the opening 18 of the storage portion 11 turns around the side of the storage object C and comes into contact so as to wrap the storage object C. And if the width of the accommodating part 11 shrink | contracts by bend | folding the PTP package 1, the to-be-contained object C has the side part of the to-be-contained object C in the end part 14 of the accommodating part 11, and the said part of the cover material 20. The object C is discharged when the side part of the object to be stored C breaks through the portion of the lid member 20 in a short time.
In the present embodiment, since the object C is a lens lock, it is easy to break through the lid member 20 by pushing the side portion of the object C against the lid member 20. Therefore, the object C can be taken out more easily by being sandwiched from the side as described above.
Moreover, in this embodiment, since the end surface 14 is formed in the accommodating part 11, it becomes easy to pinch the to-be-contained object C as mentioned above.

  Next, another preferred embodiment of the present invention will be described with reference to FIGS.
