Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a medicine bag to which a tongue piece can be attached with an adhesive layer, and particularly relates to a medicine bag in which medicine can be easily taken in and taken out and which can be reliably sealed.

[Prior Art and its Problems] A medicine bag that can securely store medicines and allow easy access to medicines is convenient to use. In particular, since medicines can have serious adverse effects if taken by mistake, it is best to prevent medicines stored in hospitals from accidentally leaving the premises as much as possible.

In the event that medicine accidentally comes out of a medicine bag, there is a risk that the medicine bag may be stored in the wrong medicine bag in a crowded large hospital pharmacy.

The present inventor developed a medicine bag that can be reliably sealed by forcibly attaching a tongue piece with an adhesive layer (Utility Model Application No. 138546/1983).

Compared to conventional medicine bags that simply fold the opening and seal it, this medicine bag has a complete seal, which minimizes the chance of the stored medicine bag accidentally leaking out. Since the mouth can be reliably sealed simply by attaching it, it is also possible to realize the feature of easily sealing the mouth.

In this medicine bag, a release sheet is attached to the adhesive layer, and after storing the medicine, the release sheet is removed and the adhesive layer is attached. For this reason, when the adhesive layer is covered with a release sheet, that is, when storing the medicine for the first time,
The adhesive layer on the tongue piece at the medicine entrance does not become sticky when storing the medicine bag, but once the release sheet is removed, the medicine tends to stick to the adhesive layer at the medicine entrance and exit, making it difficult to put in and take out medicine. There was a drawback that it was inconvenient. Ordinary bags are not used in a state where they are sealed and opened repeatedly, but since medicine is taken out and taken several times a day, the bag is opened again after being sealed. It is used in a unique situation in which the medicine is put in and taken out through the vicinity of the tongue that has been opened and sealed repeatedly.

For this reason, if there is an adhesive layer on the surface of the tongue, the medicine to be taken out tends to adhere to this adhesive layer, which has the disadvantage of interfering with taking it out. In particular, the tongue piece, which has been sealed and bent once, is in the position where the opening of the drug bag is closed, and tends to come into contact with the adhesive layer when taking out the drug, which impedes smooth delivery and stocking.

[Purpose of the invention] This invention was developed with the aim of further eliminating this drawback, and the important purpose of this invention is to:
To provide a medicine bag which can securely seal the mouth and prevent an adhesive layer from getting in the way of taking the medicine in and out, allowing the medicine to be simply and easily put in and taken out.

[Means for Solving Conventional Problems] The medicine bag of this invention has a bag-like overall shape and has a bendable tongue piece at the opening. The tongue piece is bent in the sealing direction so that the adhesive surface in contact with the surface of the backing paper is bent or curved into a concave shape, and an adhesive layer is provided on the concave adhesive surface. Furthermore, the adhesive strength of the adhesive layer is
It is adjusted to be stronger than the restoring force of the tongue in the attached state.

[Operation and Effect] As shown in Figure 2, the adhesive layer applied to the adhesive surface of the tongue, which is formed in a concave shape, prevents the medicine from coming into contact with the surface when taking it in and out, making it sticky and sticky. The tongue piece that has a 200 mm diameter does not obstruct the taking in and out of medicine. Therefore, it is possible to realize the features that medicine can be taken in and taken out simply and easily, and the mouth can be reliably sealed by the adhesive layer of the tongue piece.

Furthermore, the adhesive layer at the entrance/exit of the medicine has a structure in which it does not stick to the medicine being put in or taken out.The tongue is shaped like a tongue, and the attachment surface of the tongue is shaped into an uneven shape, making it inexpensive. It can be produced in large quantities and is much more convenient to use than methods such as attaching a release sheet to the adhesive layer when opening the package.

Furthermore, since the medicine being put in and taken out does not come into contact with the adhesive layer, foreign matter does not adhere to the adhesive layer when taking it out.
Even after repeated opening and sealing, there is little decrease in adhesiveness, and the seal can be reliably sealed for a long period of time.

[Preferred Embodiment] Hereinafter, one embodiment of this invention will be described based on the drawings.

The medicine bag 1 shown in FIGS. 1 and 2 has paper glued to form a bag shape and a tongue piece 2 provided at the opening.

On the surface of the cover 3, although not shown, fields are printed in advance for the pharmacy name, the name of the patient, the method of administration, the type of medicine stored, etc.

The tongue piece 2 is provided integrally with an extension of the opening of the cover 3.

Further, when the tongue piece 2 is bent in the sealing direction, the adhesive surface 6 that contacts the surface of the backing paper 4, the upper surface of the tongue piece in FIG. 1, is bent into a concave shape. An adhesive layer 5 is provided at the bottom of the recess, that is, at the center along the longitudinal direction of the tongue.

The shape of the tongue piece 2 may be bent into an inverted trapezoid shape or V-shape as shown in the cross-sectional views of the tongue piece 2 shown in FIGS. 2 and 3, or bent into a desired shape as shown in FIG. is curved with a radius of curvature.

The tongue pieces shown in FIGS. 1 to 4 have a groove-like overall shape and a concave attachment surface. This shape is the easiest to manufacture. The tongue piece 2 shown in FIGS. 5 and 6 is bent in a zigzag shape to form an attachment surface 6.
A depression is formed in the area.

In order to form the tongue piece 2 in a concave shape, if it is made of paper,
Can be bent and formed with or without heating.
However, if the drug bag is made of a soft synthetic resin sheet, it is best to press and bend it while heated.

Further, as shown in FIG. 5, when the adhesion surface is curved, the tongue piece 2 can be curved by shrinking the applied adhesive layer 5.

The deeper the depth d of the depression, the less the adhesive layer 5 will come into contact with the medicine being taken out and put in, but as shown in Figure 2, most medicines are packaged in a flat shape, so the depth d is quite shallow.
For example, even if the depth d is 1 to 3 mm, it will be practical. In particular, as shown in FIGS. 1 to 3, in which the adhesive layer 5 is applied only to the bottom of the recess, the depth d of the recess can be used at least sufficiently conveniently.

In particular, the tongue piece 2 once attached to the surface of the backing paper 4 by the adhesive layer 5 cannot maintain its initial bent and curved state, and the depth d of the recess becomes shallow, but the number of times it is attached is As the amount increases, the adhesive force of the adhesive layer 5 decreases to some extent, so even shallow depressions can prevent the adhesive layer 5 from interfering with the taking in and out of medicine.

In the preferred embodiment, the adhesive layer 5 is applied only to the bottom of the depression, but as shown in FIG.
It is also possible to apply the adhesive layer 5 to the entire attachment surface 6 of the tongue piece 2. In this case, the edge A of the adhesive layer 5 may come into some contact with the medicine being taken in and out, but only locally in a very narrow area.
The adhesive layer 5 hardly obstructs the taking in and out of medicine.

The tongue piece 2 shown in FIGS. 5 and 6 also has the adhesive layer 5 applied only to the recessed portion.

The adhesive layer 5 has an adhesion force stronger than the restoring force of the tongue piece 2 so that the tongue piece 2 can be easily attached by pressing it, and the tongue piece 2 that bends or curves can adhere to the surface of the backing paper. Furthermore, any material that can peel off the attached tongue when the tongue 2 is pulled can be used.

In order to prevent the tongue piece 2 and dust from adhering to the surface of each adhesive layer 5 before use, it is preferable to attach a release sheet 7 to the surface of each adhesive layer 5.

As shown in FIG. 4, the release sheet attached to the curved adhesive layer 5 is curved together with the tongue piece 2.

On the surface of the backing paper 4, a thin synthetic resin coating layer 8 is applied to the area where the tongue piece 2 is attached so that the adhesive layer 5 can be repeatedly attached thereto. The synthetic resin coating layer 8 is designed so that when the adhesive layer 5 is peeled off, the paper pulp fibers on the surface of the backing paper 4 are peeled off and attached to the adhesive layer 5, thereby reducing the adhesive force of the adhesive layer 5. prevent.

By the way, in the medicine bag of the present application, the tongue piece 2 does not necessarily need to adhere to the backing paper of the medicine bag over the entire width of the opening, so it is also possible to provide the tongue piece 2 in a part of the middle of the opening.
