Description

  The present invention relates to a medicine wrapping paper for medicine packaging that stores medicines to be packaged for each patient according to the contents of a prescription in a hospital or a pharmacy.

  Conventional medicine packaging paper for medicine packaging is provided to a patient so that the medicine is packaged for each dose by an automatic medicine packaging machine or the like according to the contents of the prescription, and the medicine can be administered in the same packaging bag. This sachet is made of polypropylene as a base material so that even a patient with no force can easily tear it. In this sachet, a belt-like sheet material coated with heat-welding polyethylene on polypropylene is folded in two in the longitudinal direction to form continuous bags by thermal welding, and the continuous sachets can be separated from each other. The perforation for cutting is put in the heat welding part orthogonal to a longitudinal direction, and it is handed over to each patient according to a prescription. For this reason, patients take their packaging bags separately from the perforation every time they take it.

However, since such a sachet is made of polypropylene, if the sachet is not cut with care when it is cut off from the perforation, the sachet itself other than the perforation may be torn or the sachet not taken this time The medicine sometimes spilled off. In addition, even if the drug does not spill out, the sealing performance may be impaired and the storage stability may deteriorate.
Therefore, in order to prevent the bag from tearing when it is separated from the perforation by shifting the separating direction and tearing direction of the packaging bag, and to easily tear the packaging bag when taking it, There has been proposed one provided with a tearing portion for tearing the packaging bag in a direction intersecting with the direction of the perforation for cutting the packaging bag (see, for example, Patent Document 1). Moreover, what formed the character-shaped notch in the perforation which cuts off a packaging bag is proposed (for example, refer patent document 2). Further, there has been proposed one in which the tear guide display printed near the tear portion is changed in accordance with the longitudinal weld portion formed by the longitudinal heat seal mechanism (see, for example, Patent Document 3).

  In the conventional medicine wrapping paper for medicine packaging, the sachet is formed long in the longitudinal direction of the long sheet, that is, in the direction intersecting with the perforation, in order to facilitate the medicine packaging. Therefore, after separating the sachet from the medicine wrapping paper, when opening the sachet in the direction crossing the perforation direction of the sachet and taking the drug, the opening of the sachet becomes larger and the patient For this reason, it was difficult to take the medicine in the sachet.

  The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a medicine wrapping paper for medicine packaging that can form a sachet that a patient can easily take medicine.

The present invention employs the following means in order to solve the above problems. That is, the present invention is formed into a long sheet shape using polypropylene as a base material, and a packaging part is formed by continuously dividing a storage part for storing medicines in the longitudinal direction of the long sheet into a plurality of parts by a heat welding part. The thermal welded portion is formed by a longitudinal welded portion that intersects the longitudinal direction of the long sheet and divides the storage portion into an arbitrary width and a lateral welded portion that thermally welds the mating end of the long sheet. The medicine wrapping paper for medicine packaging is characterized in that a plurality of holes for inducing shearing in a direction crossing the longitudinal direction of the long sheet are provided in the lateral weld portion.
According to the medicine wrapping paper for drug packaging of the present invention, by providing a plurality of holes in the lateral weld portion, when a shearing force is applied to the lateral weld portion, the lateral weld portion is formed between one end of the lateral weld portion. When the shearing force is further applied and a shearing force is further applied, the lateral welded portion is sheared between one hole and another hole. After the lateral welded portion is sheared so as to be guided to the hole by the shearing force in this way, when the shearing force is further applied, the storage portion is sheared, and the storage portion crosses the longitudinal direction of the long sheet. It will be opened. As a result, the patient can take the medicine in the sachet with the opening of the storage part being small.

In the medicine packaging paper for packaging medicine according to the present invention, the plurality of holes are arranged close to a predetermined interval in the longitudinal direction of the long sheet.
According to the medicine wrapping paper for medicine packaging of the present invention, a plurality of holes are arranged close to a predetermined interval in the longitudinal direction of the long sheet, so that shear force can be applied at any location of the laterally welded portion of the packaging bag. Even if is added, the transverse welded portion is sheared between the sheared portion and a certain hole close to the sheared portion. Therefore, the horizontal welded portion is easily sheared from an arbitrary position of the lateral welded portion of the packaging bag.

  According to the medicine wrapping paper for medicine packaging of the present invention, the patient can take the medicine in the sachet with the opening of the storage part being small, so that the sachet is easy for the patient to take the medicine. can do.

  In addition, according to the medicine wrapping paper for drug packaging of the present invention, since the lateral welded portion is easily sheared from an arbitrary position of the lateral welded portion of the sachet bag, the storage portion of the sachet bag can be easily opened.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a partial perspective view of a medicine wrapping paper for medicine packaging to which the present invention is applied. FIG. 2 is a plan view of a medicine wrapping paper for medicine packaging. FIG. 3 is a plan view of the sachet separated from the medicine wrapping paper.
As shown in FIG. 1, the medicine wrapper 1 includes a polypropylene sheet 2 and a polyethylene sheet 3 superimposed on one surface of the polypropylene sheet 2 and is formed in a long sheet shape. The medicine-wrapping paper 1 is folded in two so that the polyethylene sheet 3 is on the inner side and both ends in the longitudinal direction of the long sheet, that is, the mating ends are joined. At this time, as shown in FIG. 2, the longitudinal ends of the medicine-wrapping paper 1 are heat-welded to form the laterally welded portions 4, and the medicine-wrapping paper 1 is partitioned at equal intervals in the longitudinal direction. A vertical welded portion 5 is formed in a direction orthogonal to. That is, the sachet 8 is formed by dividing the storage portion 7 that can store the medicine A at equal intervals by the thermal welding portion 6 formed by the horizontal welding portion 4 and the vertical welding portion 5. Here, as shown in FIG. 3, the sachet 8 is longer in the longitudinal direction of the long sheet so that the length b of the longitudinal weld portion 4 is longer than the length a of the lateral weld portion 5. It is divided and formed. In addition, before the horizontal welding part 4 is heat-welded, the chemical | medical agent A is thrown in into the packaging bag 8. FIG.

The lateral weld 4 is provided with a plurality of circular holes 9 having a smaller diameter than the width of the lateral weld 4. These holes 9 are arranged close to a predetermined interval, that is, at the same distance as the diameter of the holes 9, and are arranged in three rows parallel to the longitudinal direction of the long sheet. Further, these holes 9 are arranged so that the rows of these holes 9 are close to each other in order to induce shearing in a direction crossing the longitudinal direction of the long sheet.
The longitudinal weld 5 is provided with a perforation 10 for cutting, which is separated for each sachet 8 in a straight line. The dividing bag 8 is separated from the medicine-wrapping paper 1 by tearing the perforation 10 while applying a shearing force.

In the medicine wrapping paper for medicine packaging thus configured, after separating the sachet 8 from the medicine wrapping paper 1, the sachet 8 is cut and opened, and the patient takes the medicine stored in the storage unit 7. . That is, the procedure is as follows.
By applying a shearing force with a finger or the like in the direction crossing the longitudinal direction of the medicine wrapper 1, that is, along the perforation 10, the packaging bag 8 is separated from the medicine wrapper 1. Thereafter, when a shearing force is applied to the transverse weld portion 4 provided with the holes 9 in the direction crossing the longitudinal direction of the packaging bag 8, that is, in the direction of the arrow in FIG. 3, the transverse weld portion 4 is torn. It is. At this time, since resistance to the shearing force is weak between one end of the lateral weld portion 4 and the hole 9 close to the one end, the gap between one end of the lateral weld portion 4 and the hole 9 close to the one end thereof is reduced. The horizontal weld 4 is sheared so as to induce shearing. Further, when a shearing force is applied to the lateral weld 4 with a finger or the like, the lateral weld 4 is torn between the hole 9 and another hole 9. When a shearing force is further applied, the lateral welding portion 4 is cut and the cut end reaches the storage portion 7, and the storage portion 7 is cut to open the packaging bag 8.

  In this case, when the sachet 8 formed by being divided so as to be elongated in the longitudinal direction is torn in the direction intersecting with the longitudinal direction using the holes 9 of the lateral welding portion 4, the direction is intersected with the longitudinal direction. Since it is in the opened state, the patient can take the medicine in the packing bag 8 with the opening of the packing bag 8 being small. Therefore, the sachet 8 that allows the patient to easily take the medicine can be formed.

  Further, by arranging the hole 9 in the longitudinal direction so as to have the same distance as the diameter of the hole 9, even if a shearing force is applied at any point at one end of the lateral welding portion 4 of the packaging bag 8, The lateral weld 4 is sheared between the holes 9 close to the location. Therefore, the horizontal welding part 4 is easily sheared from any location at one end of the horizontal welding part 4 of the packaging bag 8. Therefore, the sachet 8 can be easily opened from any location of the lateral welding portion 4.

In the above embodiment, the shape of the hole 9 is not limited to a circular shape, and may be any shape as long as it induces shear in a direction crossing the longitudinal direction.
