Description

The present invention relates to a package for a drug sheet capable of accommodating a drug sheet containing a drug.

A PTP (Press Through Package) sheet for packaging an orally administered drug such as a tablet has a plurality of pockets (also referred to as "blisters"), and usually one drug is enclosed in each pocket. The sick person crushes the pockets of the PTP sheet to take out the required amount of drugs and takes them.

Such a PTP type drug sheet is convenient, and a sick person who can lead a daily life often takes the drug at home. However, some prescription drugs brought into the home may include drugs with a high risk of side effects, such as anticancer drugs. It is necessary to manage such dangerous drugs with great care, such as storing the drug sheet in a special place so that children and infants do not carelessly take it out or accidentally swallow it. be.

Conventionally, packaging bodies and instruments have been proposed in which measures are taken to prevent children and the like from easily taking out the drug.
For example, Patent Document 1 discloses a blister pack integrally provided with a protective panel facing the foil surface (the surface on which the drug is taken out) of the drug sheet. The protective panel comprises an array of holes substantially equal to the array of pockets containing the drug, with a first position where the holes are partially offset from the pocket and a first position where the holes are aligned with the pocket. It is possible to slide to and from the position of 2. Further, the spring web formed between the medicine sheet and the protective panel urges the medicine sheet to the first position.

Further, for example, the device for holding a blister pack described in Patent Document 2 is provided with a base portion formed by arranging openings corresponding to a plurality of pockets in a housing for accommodating the blister pack. It is possible to move between the first position where the pocket and the opening of the base member are displaced from each other and the second position where the pocket and the opening are aligned. Further, the device of Patent Document 2 is provided with a lock mechanism for locking the pocket to the first position, and further moves from the lock position for locking the blister pack to the first position to the second position. It is equipped with operating means that can be operated to possible unlocked positions.

However, in the blister pack described in Patent Document 1, by moving the drug sheet by the distance corresponding to the radius of the hole against the urging force of the spring web, all the pockets match the position of the hole. The drug can be taken out relatively easily.
Further, according to the device for holding the blister pack described in Patent Document 2, the drug cannot be taken out when the blister pack is in the lock position which is the first position. However, in order for the user to remove the drug from the blister pack, the blister pack must first be moved from the locked position to the unlocked position and then from the unlocked position to the second position, and the drug must be taken. The operation of taking out the drug is complicated for the person.

As mentioned above, the drug sheet used at home needs to have a so-called child resistance function that prevents children and the like from inadvertently taking out the drug due to mischief, etc., but it is easy for the user. It can be said that it is more convenient to be able to take out the drug with a simple operation. The above-mentioned conventional drug packages and appliances described in Patent Documents 1 and 2 have not solved the conflicting problems regarding the taking-out performance of such drugs.

Further, PTP sheets are distributed in various forms depending on the type, size, number of doses and the like of the drug. However, in the conventional package, it is necessary to prepare a special package designed according to the size, arrangement, number, etc. of the pockets of the PTP sheet, and it is not versatile for various drug sheets. ..

The present invention has been made in view of such a problem, and provides a package for a drug sheet which has both an operation performance for taking out a drug and a protective function and is versatile enough to be used for various drug sheets. The purpose is.

The present invention is a package for a drug sheet for packaging a drug sheet in which a plurality of rows of pockets containing a drug are arranged, and the base sheet and an inner slidably arranged facing the base sheet. It is a package for a drug sheet that includes a sheet and can be packaged between the inner sheet and the base sheet with the pocket engaged with the inner sheet.

The package for a drug sheet has a hole in the base sheet for taking out the drug, and when the inner sheet is slid to one side, one of the pockets of the drug sheet is aligned with the position of the hole. The elastic holding portion that holds the drug sheet while alternately repeating the possible state and the drug removal impossible state in which none of the pockets match the position of the hole is the base sheet and the inner sheet. It is preferably formed in the engaging portion.

Further, in the package for a drug sheet, the elastic holding portion has a wavy recess formed at a predetermined pitch along the edge of the folded portion of the base sheet, and the end portion of the inner sheet has the same or an integer as the predetermined pitch. It is preferable that the wavy convex portions formed at double pitch are engaged with each other.

Further, it is preferable that the inner sheet of the package for the drug sheet has elongated holes that expose the rows of pockets of the drug sheet.

According to the package for a drug sheet of the present invention, it is possible to improve the operation performance of taking out the drug by the person taking the drug, and also to have a protective function that the drug cannot be taken out accidentally or carelessly by a child or the like. In addition, it is possible to handle various chemical sheets simply by standardizing the base sheet and replacing the inner sheet.

FIG. 1 is a perspective view of a base sheet 20, an inner sheet 30, and a drug sheet 40 packaged therein, which constitute a package. FIG. 2 is a front view (a), a side view (b), and a front view (c) of the developed base sheet. 3A and 3B are a front view of the inner sheet, a side view of the inner sheet, and a front view of the inner sheet. As shown in the figure, the package 10 includes a base sheet 20 and an inner sheet 30 slidably arranged facing the base sheet 20. For example, the drug sheet 40, which is a PTP sheet, is packaged between the base sheet 20 and the inner sheet 30. The inner sheet 30 is slidable on the base sheet 20 together with the drug sheet 40, and the longitudinal direction in which the inner sheet 30 slides is described here as the "front-back" direction.

The base sheet 20 and the inner sheet 30 are integrally formed from a sheet-shaped molded body (hereinafter referred to as "sheet-shaped molded body") of a thermoplastic transparent resin having flexibility (bending elasticity), respectively. As the material of the sheet-shaped molded product, A-PET having a thickness of, for example, 0.1 to 1.0 mm, preferably 0.25 to 0.8 mm can be used. The tensile elastic modulus indicating the mechanical properties of the prototype sheet-shaped molded product is 2020 MPa (thickness 0.3 mm, measured value measured by the ISO 527-3: 2012 (JIS K 7127) test method).

First, the base sheet 20 is formed through a step of processing a sheet-shaped molded body shown in the developed view of FIG. 2 by an appropriate press molding method (vacuum forming, thermoforming, etc.) and bending a predetermined portion. The base sheet 20 includes a main body seat portion 21 that is long in the front-rear direction, a right turn-back portion 22 that is folded back on the left and right sides of the main body seat portion 21 and sandwiches both side portions of the inner sheet 30 so as to be slidable, and a left turn-back portion 23. ing. Further, a rear folding portion 24 is formed at the rear portion of the main body seat portion 21. The right turn portion 22, the left turn portion 23, and the rear turn portion 24 have land cut portions 22a, 23a, and a taper cut portion 24a so as not to overlap each other when folded onto the upper side surface of the main body sheet portion 21, respectively. 24a is formed.

Further, a drug take-out hole 25 for taking out the drug from the drug sheet 40 is formed in the center of the front portion of the main body sheet portion 21. The drug take-out hole 25 is preferably a long hole that is long in the front-rear direction. The minor axis of the drug take-out hole 25 is larger than the diameter of the pocket 42 of the target drug sheet 40. The major axis of the drug take-out hole 25 is smaller than the distance between the adjacent pockets 42 and 42 of the target drug sheet 40 (the total length of the two pocket diameters and the distance between both pockets). The drug take-out hole 25 according to the embodiment having a pocket diameter of φ7.5 to 10.0 mm has a minor diameter of 12 mm and a major diameter of 15 mm.

When the rear end of the inner sheet 30 is in the end position (accommodation position described later) in contact with the rear folding portion 24, the front portion of the drug sheet 40 closes all or a part of the hole 25. At this end position, the rear portion of the inner seat 30 enters between the main body seat portion 21 and the rear folding portion 24, and further movement of the inner seat 30 to the rear is restricted.

It is preferable that an uneven annular portion 25a is extruded on the peripheral edge portion of the drug take-out hole 25. With such an annular portion 25a, the bending rigidity of the peripheral portion of the drug take-out hole 25 can be increased. In particular, a sufficient reaction force can be generated by suppressing the amount of deformation of the main body sheet portion 21 as much as possible against the force of crushing the pocket 42 for taking out the drug.

Further, wavy recesses 221 and 231 are formed symmetrically along the edges of the right turn portion 22 and the left turn portion 23 of the base sheet 20. As will be described later, these wavy recesses 221 and 231 together with the wavy convex portions 321 and 331 of the inner sheet 30 form an elastic holding portion according to the present invention.

Next, the inner sheet 30 is formed as a sheet-shaped molded body as illustrated in FIG. 3 by the same press molding method as the base sheet 20 described above. The inner sheet 30 includes a slide sheet portion 31 having a rectangular shape having substantially the same dimensions as the main body sheet portion 21 of the base sheet 20 described above. The right extrusion molding section 32, the left extrusion molding section 33, and the front extrusion molding section 34 are continuously formed on the slide sheet section 31 at the same height.

The right extrusion molding portion 32 is formed so as to extend along the longitudinal direction in the right portion of the slide sheet portion 31, and the left extrusion molding portion 33 is formed so as to extend along the longitudinal direction in the left portion of the slide sheet portion 31. The right extrusion molding section 32 and the left extrusion molding section 33 have a symmetrical shape. The pre-extrusion molding unit 34 connects these at the front portions of the right extrusion molding unit 32 and the left extrusion molding unit 33.

A wavy convex portion 321 is formed at the outer end portion of the right extrusion molding portion 32 along the longitudinal direction thereof. Further, a wavy convex portion 331 is formed at the outer end portion of the left extrusion molding portion 33 along the longitudinal direction thereof. The pitch (P2) of these wavy protrusions 321 and 331 is the same as or an integer with respect to the pitch (P1) of the wavy recesses 221 and 231 so that they can engage with the wavy recesses 221 and 231 of the base sheet 20 described above. It is doubled (doubled in this embodiment, that is, P2 = 2 × P1).

FIG. 4 shows dimensional examples of the pitch P1, the depth D, the inner diameter R1 of the wavy concave portion, and the pitch P2, the height H, and the outer diameter R2 of the wavy convex portion in the elastic holding portion according to the embodiment.

At the center of the inner sheet 30 sandwiched between the right extrusion molding section 32 and the left extrusion molding section 33, the pockets 42, 42, ... An elongated hole 35 is formed through which everything is inserted and exposed.

Next, a method of using the package 10 according to the present embodiment will be described. As shown in FIG. 5, the drug sheet 40 packaged in the package 10 is sandwiched between the inner sheet 30 and the base sheet 20.

Here, the drug sheet 40 has a plurality of rows of pockets (also referred to as "blisters") 42, 42, ..., And each pocket 42 is usually filled with one tablet. ing. The drug sheet 40 may be vertically cut according to the number of tablets to be taken at one time. In this embodiment, the number of tablets to be taken at one time is one, and the pockets 42, 42, ... Of the drug sheet 40 are divided into one row according to the number of tablets to be taken at one time. However, in carrying out the present invention, the drug sheet having a plurality of rows of pockets may be packaged without being separated.

Specifically, first, the chemical sheet 40 with the pockets 42, 42, ... With the side facing up is covered with the inner sheet 30 from the lower surface side (flat surface side without the extruded portion) and has a long hole. Insert all pockets 42, 42, ... In 35. When the inner sheet 30 and the drug sheet 40 are in contact with each other facing each other, the pocket rows are exposed from the elongated holes 35, and the pockets 42 and 42 at both ends are engaged with the semicircular ends of the elongated holes 35. Become.

Next, the inner sheet 30 overlapped with the drug sheet 40 is inserted into the space between the main body sheet portion 21 of the base sheet 20, the right turn-back portion 22 and the left turn-back portion 23, and the drug sheet 40 is inserted into the main body sheet portion 21. The inner sheet 30 is slid toward the inside of the base sheet 20 while being in contact with the base sheet 20. At this time, the wavy concave portion 221 of the right turning portion 22 and the wavy convex portion 321 of the inner sheet 30 are elastically fitted, and the wavy concave portion 231 of the left turning portion 23 and the wavy convex portion 331 of the inner sheet 30 are elastically fitted. Fits into. The elastic holding portion composed of these causes a feeling of moderation (click feeling) associated with the sliding of the inner sheet 30.

At a position where the rear portion of the inner sheet 30 is under the rear folding portion 24 of the base sheet 20 (this position is referred to as a “containment position”), the inner sheet 30 and the drug sheet 40 engaged with the inner sheet 30 by the elastic holding portion described above are used. Is retained, and at the same time, the front part of the drug sheet 40 closes all or part of the drug take-out hole 25 (see FIG. 6). That is, in the accommodation position of the inner sheet 30, any pocket 42 of the drug sheet 40 does not match the position of the drug take-out hole 25, and the drug cannot be taken out. In this state, the drug does not accidentally spill from the drug sheet 40, and the package 10 can be safely stored and carried. In addition, the risk of accidental drug removal due to mischief by infants or the like can be reduced.

In addition, the drug user can easily take out the drug from the package 10 by sliding the inner sheet 30 in front of the base sheet 20. That is, when the inner sheet 30 is slid forward by 2 pitches (2 × P1) from the above-mentioned accommodation position, the leading pocket 42 matches the position of the drug take-out hole 25, and the drug is taken out from the pocket 42 through the drug take-out hole 25. Is kept in a state where the drug can be taken out (see FIG. 7).

When the inner sheet 30 is further slid forward by one pitch (P1) from the drug take-out state of FIG. 7, any pocket 42 is held again in the drug take-out impossible state that does not match the position of the drug take-out hole 25 (FIG. 7). 8). Then, when the inner sheet 30 is further slid by one pitch (P1), the second pocket 42 then matches the position of the drug take-out hole 25 and is held again in a position where the drug can be taken out from the pocket 42. (See FIG. 9).

In this way, when the inner sheet 30 is slid forward, one of the pockets 42 of the medicine sheet 40 is in a state where the medicine can be taken out in accordance with the position of the medicine take-out hole 25, and any pocket 42 is in the position of the medicine take-out hole 25. The drug sheet 40 is elastically held by the package 10 while alternately repeating the incompatible state in which the drug cannot be taken out and causing a feeling of moderation in each state. Since the medicine can be taken out by sliding the inner sheet 30 in only one direction, the operability of taking out the medicine by the user can be simplified and improved.

Further, in the package 10 of the present embodiment, even if the drug sheet 40 has a different diameter and number of pockets, it can be replaced with an inner sheet 30 suitable for the drug sheet. Here, the inner sheet of FIG. 10A is an embodiment for a PTP sheet having a pocket diameter of φ7.8 mm and a number of pockets of 5. The inner sheet of FIG. 10B is an embodiment for a PTP sheet having a pocket diameter of φ9 mm and a number of pockets of 5. The inner sheet of FIG. 10C is an embodiment for a PTP sheet having a pocket diameter of φ10 mm and a number of 5 pockets. As described above, by using the inner sheet fitted to each drug sheet, the base sheet 20 can be shared, and the package 10 having high versatility can be provided.
