ABSTRACT:
TECHNICAL FIELD
The present invention relates to a press-through pack, a sealing sheet for a press-through pack and a taking-out method of tablet. Specifically, it relates to a press-through pack wherein a solid material such as a tablet or the like contained therein can be taken out easily one by one and also plural solid materials or all solid materials are taken out at one time if desired, a sealing sheet appropriate for producing such a press-through pack, and a taking-out method of tablets wherein all dividable tablets contained in the press-through pack can be divided at one time and all of the divided tablets in each storage recess of an accommodation body can be obtained at one time.
BACKGROUND ART
A press-through pack (generally called as PTP package) can contain a solid material one by one in each storage recess (or pocket) tightly and hygienically sealed and a solid material contained in the storage recess can be easily obtained one by one. Therefore, such a press-through pack has been widely used for individually packing medicines such as a tablet and a capsule, and confections such as a candy.
FIG. 7
shows a sectional view of one embodiment of such a press-through pack. The press-through pack
101
is provided with an accommodation body

and a sealing sheet

and is constructed such that an adhesive layer

one by one.
On the other hand, the dosage amount of medicine is required to be varied depending on the weight, age and soon of the patient to be dosed. Therefore, many tablets are provided with a dividing line along which the tablets are easily divided by fingers or tools.
However, the prior press-through pack
101
is designed such that the solid materials T, . . . T each contained in the recesses
102
a
, . . .

are obtained one by one. Therefore, when medicine containing plural different components is dividedly packed for one dosage to a patient at a hospital, a clinic or a pharmacy, a pharmacist takes the solid materials T, . . . T out of the press-through pack
101
one by one and the removed solid materials T, . . . T are dividedly packed for one dosage by means of a dividedly packing machine. It takes trouble and time for taking the solid materials T, . . . T out of the press-through pack
101
one by one. It is requested by a pharmacist and an administrator at a medical site to provide a press-through pack by which the solid materials T, . . . T can be obtained one by one and also easily all the solid materials T, . . . T can be obtained at one time.
Aluminum foil is widely used as the substrate
103
of the sealing seat
105
because it is highly dampproof, the solid materials T can be easily obtained, and it is posh. However, the aluminum substrate
103
and the accommodation body
102
aren't separately disposed after all the solid materials T, . . . T are taken out of the press-through pack
101
so that the treatment of disposed materials is difficult and they aren't recycled.
DISCLOSURE OF THE INVENTION
The present invention is proposed to meet the above-mentioned request.
Accordingly, an object of the invention is to provide a press-through pack by which the solid materials stored therein can easily be obtained one by one, plural solid materials or all of the solid materials can be obtained at one time and which can be disposed after separating a sealing sheet and an accommodation body. And it is also an object of the invention to provide a sealing sheet which can easily make such a press-through pack.
Many dividable tablets are obtained from a press-through pack
101
one by one and each one is manually divided. Such a work takes a lot of troubles and long time although they have dividing lines so as to be easily divided by a punch as mentioned above. It is expected by pharmacists for a long time to propose a taking-out method of tablets wherein a large amount of tablets are divided at one time and the divided tablets are easily gathered at one time in order to improve efficiency of dispensation work.
A further object of the present invention for satisfying the pharmacist's request is to provide a taking-out method wherein dividable tablets contained in a press-through pack are taken out one by one, also a lot of the dividable tablets are divided at one time, and the divided tablets are gathered at one time.
According to the claim
1
of the present invention, a press-through pack comprised of an accommodation body having plural storage recesses provided with sheet like portions therebetween, and a sealing sheet having a substrate on which one surface side an adhesive layer is formed, said accomodation body being sealed tightly by said sealing sheet in a manner that said adhesive layer and said sheet like portions are bonded to each other with a solid material contained in each of said plural storage recesses wherein, said sealing sheet is made of such material that the part of said sealing sheet responding to said recess, a part in which a solid material is contained, is partly ruptured without causing floating and peeling of adhesion portion between said adhesive layer of said sealing sheet and said sheet like portion of said accommodation body when pushing the projecting portion of the outer side of said recess with fingers, whereby said solid material contained in said recess is taken out and said sealing sheet is further bonded to said sheet like portions of said accommodation body in a manner that said sealing sheet is easily peeled off from said accommodation body.
Here “the sealing sheet is further bonded to the sheet like portions of the accommodation body in a manner that the sealing sheet is easily peeled off from the accommodation body” means the sealing sheet is bonded to the sheet like portion of the accommodation body so that the sealing sheet is exfoliated from the sheet like portion of the accommodation body easily and without being ruptured when a part of the sealing sheet of the press-through pack is peeled off.
The material of the accommodation body or the substrate of the sealing sheet isn't limited if it can be used for a press-through pack for packing pharmaceuticals, drugs for animals and plants, confections, health foods, fishing baits, toys and so on.
The press-through pack of the claim
2
of the present invention is characterized in that the solid material is a dividable tablet.
More than one dividable tablet may be contained in any of the storage recesses of the accommodation body of the press-through pack. The dividable tablet may be contained in the storage recess in such a manner the surface having a dividing li
