Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to plasters such as ointments or patches such as paste-like poultices.

(Prior Art) It is widely practiced to apply a patch to the affected area for pain relief or anti-inflammation in the event of a sprain, bruise, muscle pain, joint pain, or bone fracture pain. Conventionally, this type of patch has been made by applying a paste as an analgesic and anti-inflammatory drug to a uniform thickness over the entire upper surface of a cloth such as non-woven fabric, and then covering the surface of the paste with a plastic film. It was hot. Each bag contained one or more than ten patches. If more than ten patches are stored in a bag, when the bag is opened to use only one patch, for example, the remaining patches will not come into contact with the outside air. I folded the opened part of the bag and stored it.

In addition to the above-mentioned patches, the following are well known as patches having a bag-like component for accommodating a plaster that acts as analgesic and anti-inflammatory on the affected area. Specifically, Japanese Patent Application Laid-Open No. 59-155267 discloses that a transdermal absorption capsule is provided in the center of an adhesive layer on a base fabric as a support, and a pad containing the capsule is attached to cover an upper pad. A covering cloth is provided so that the drug is absorbed through the skin through the covering cloth, and preferably a release paper is further provided and used by peeling it off before use. Utility Model Application No. 57-17614 discloses a double-sided release paper that is interposed in a laminated plaster with a large number of notches, and is interposed between the laminated parts of the plaster to make it easy to peel off and to have appropriate releasability. Gauze your body/
When applied to a support piece such as cotton cloth and then attached to the affected area together with the support piece, use flannel, non-woven fabric, etc. for the inner and outer layers, interpose a synthetic resin film as a poorly permeable middle layer, overlap them, and then apply the adhesive to the three sides. The edges are heat-sealed and a paste is housed inside, and when in use, the joint is removed and unfolded to be applied. A pair of microporous membranes are stacked on top of each other and bonded to each other along the periphery to provide a micro-release enzyme preparation in which the enzyme is released into a porous substrate having an enzyme storage layer in a sealed internal space. JP-A No. 55-49314 discloses a method in which an outer cloth is pasted on the outer surface of an inner cloth on which an ointment patch is evenly spread, the two are folded in the center and overlapped, and a narrow strip is formed on the outer edge. In Japanese Utility Model Publication No. 48-23516, a release paper is protruded in parallel to facilitate the unfolding of both fabrics during intervening use, in which a drug is encapsulated in microcapsules and is encapsulated in an infiltrative fiber layer. One side of the layer is covered with a waterproof piece such as plastic film, and the other side is covered with a breathable piece such as non-woven fabric or gauze with many pores as the skin-contact side, with the top and bottom sides glued together. , Utility Model Publication No. 46-5360 is made by wrapping chemicals in a bag-like jacket and compressing them flat, but the jacket is made of a porous film and thin paper attached to its surface to improve breathability. In addition, even if the thin paper absorbs moisture, it is reinforced with a synthetic resin film, so it has high moisture resistance and will not tear unnecessarily. In Utility Model Publication No. 45-3598, an ointment layer is provided on the left and right sides of the synthetic resin film that are similar in shape to the center line, and an adhesive substance is applied to the periphery. This patch is made of a synthetic resin film that is folded in half from the center line with an ointment inside, with a separator covering the adhesive material on one side interposed.

However, in any case, no effect has been found on the bag-like component that allows the plaster to be individually packaged and sealed and made available for use by being opened and peeled off individually.
As mentioned above, nothing has been suggested to avoid the problems that arise from the storage conditions in which multiple sheets are normally stored in a single bag.

(Problem to be solved by the invention) However, with the above-mentioned conventional patch, after opening the bag,
Even if the unsealed part of the bag is folded so that the remaining patch does not come into contact with the outside air, the inside of the bag is not completely isolated from the outside air. As a result, the volatile active ingredients and moisture contained in the remaining patches evaporate from the open areas around the patches and nonwoven fabrics, reducing the analgesic and anti-inflammatory functions of the patches. However, if the evaporation continued for a long period of time, the plaster would harden and irritate the skin, and the patch would easily peel off from the affected area. In addition, when one patch is stored in a bag, one bag is required for one patch, resulting in high costs.

Structure of the Invention (Means for Solving the Problems) The present invention is a patch having a bag-like component containing a plaster that acts as analgesic and anti-inflammatory for the affected area, which can be shielded from the outside air. The bag consists of a support body on which the plaster is placed, and a cover body that covers the plaster body and whose entire periphery is tightly attached to the support body. The gist of the patch is that it is filled with plaster, stretched to a uniform thickness, solidified, and formed so that it can be applied to the affected area with the sealed entrance cut open and the cover peeled off. It is something.

(Function) In this invention, each patch is placed in a bag consisting of a support and a cover and sealed to isolate it from the outside air, which reduces the amount of active ingredients contained in the patch and prevents moisture from entering. Evaporation is prevented, and the deterioration of the analgesic, anti-inflammatory, and other functions of the plaster on the affected area is also prevented. In addition, since the support and cover are used as a bag, there is no need to make a separate bag for storing the patch from the support and cover for the patch, which not only reduces costs, but also reduces the cost of the bag. It also saves you the trouble of storing patches inside each time.

(Example) Hereinafter, an example embodying this invention will be described in the first to
This will be explained according to Figure 3.

A cloth 2 such as a nonwoven fabric is attached to the surface of a support 1 made of a rectangular plastic film, and a cover 3 made of a plastic film having the same size as the support 1 is superimposed on the surface. ing. The four side edges of the support body 1 with the cloth 2 and the cover body 3 are each fused and sealed to form a bag 4, in which one plaster 5 is housed.

When using the patch constructed as described above, cut one side edge of the bag 4, open it, peel off the cover body 3 that covers the surface of the plaster 5, and apply it to an affected area such as a sprain or bruise. Paste. At this time, secure the patch with a bandage or tape as necessary.

As described above, in this embodiment, the support 1
Since the plaster 5 is placed one by one into the bag 4 formed from the and cover body 3 and sealed, unlike in the case of conventional patches, after using some of the patches in the bag, the remaining There is no risk that the active ingredients contained in the plaster of the patch will decrease or that the water will evaporate. Therefore, the plaster 5 provides pain relief for sprains, bruises, etc.
There is no fear that the anti-inflammatory function will deteriorate, and the function of the plaster 5 immediately after manufacture is maintained for a long period of time.
In addition, since the support 1 and the cover 3 are used as the bag 4, unlike in the case of conventional patches, the bag for storing the patch is separate from the support 1 and the cover 3 of the patch. There is no need to make one, and the trouble of storing each patch in the bag can also be saved. In such a case, the cost is lower than when each patch is put into a bag one by one.

Next, a method for manufacturing this patch will be explained.

First, the cover body 3 is superimposed on the surface of the support body 1, and the three outer edges other than the inlet 6 are fused (or bonded) to form the bag 4 (see FIG. 3). Next, liquid plaster 5 is filled into the bag 4 through the inlet 6, and the inlet 6 is further fused (or bonded). The liquid paste 5 may be one that melts when heated and hardens when cooled, or may be one in which a reactant is mixed in advance so that it hardens over time.

Note that the present invention is not limited to the above embodiments, and may be implemented as follows.

(1) As shown in Fig. 4, a plurality of plasters 5 are successively placed on the upper surface of a long strip-shaped support 1 at predetermined intervals, and then the same long strips are placed on the upper surface of these plasters 5. The cover bodies 3 of the above are overlapped, and the cover bodies 3 and the support body 1 are fused to each other at their both side edges and between each plaster body 5 to form a plurality of bags 4 arranged in a continuous manner, and further, these bags are The patch may be manufactured by stretching the paste 5 in the patch 4 into a rectangular planar shape so that the entire thickness is uniform. When manufactured in this manner, a plurality of patches are connected in a band-like state. These patches may be cut into individual sheets during the manufacturing process, or perforations (not shown) may be made so that they can be easily separated one by one after manufacturing.

(2) In the same bag 4 as in the embodiment shown in Figs. 1 to 3 above,
A paste 5 which is not liquid but paste-like (viscosity 500 to 5,000,000 cps) is filled, and then the entrance 6 of the bag 4 is fused and sealed, and the paste 5 is pressed from above and stretched to a uniform thickness to form a patch. may be manufactured.

(3) The shape of the bag 4 may be changed to a shape other than a rectangle, such as a square or an oval.

(4) In the above examples, the material was embodied in a plaster, but it may also be embodied in a paste-like poultice.

(5) In the above embodiment, the support body 1 and the cover body 3 were made of plastic film, but cloth impregnated with synthetic resin and treated to prevent the active ingredients contained in the paste from decreasing, or aluminum foil may also be used. It may also be a sheet made of foam covered with a synthetic resin film.

Effects of the Invention As detailed above, the bag-like component for accommodating the plaster of the present invention is sealed in an individual bag consisting of a support body on which the plaster is placed and a cover body, compared to various known ones. It has the effect of being able to be used by forming a state, cutting it, unwrapping it, and peeling it off.
To explain further, in this invention, each patch is placed in a bag consisting of a support and a cover and sealed to isolate it from the outside air, which reduces the amount of active ingredients contained in the patch and evaporates water. It also prevents the plaster from deteriorating its analgesic, anti-inflammatory, and other functions on the affected area.Furthermore, since the support and cover are in the form of a bag, the bag for storing the patch can be used to store the patch. There is no need to manufacture the support body and the cover body separately, which not only reduces costs but also eliminates the trouble of storing the patch in the bag.
