Description

A manufacturing method of poultice and poultice therefor}

The present invention relates to a method for producing a poultice agent and a poultice agent, and more particularly to maintain a stable adhesive state without detachment of the end during use, and to have a structure that can be easily detached without pain or skin damage even when removed. A method for preparing a poultice agent and a poultice agent thereof.

In general, the poultice used by affixing to the skin of the human body should be removed after using a certain amount of time affixed on the skin, but if the adhesive strength is too strong, it may not only be accompanied by pain during removal but also damage to the skin. For this reason, since the conventional poultices are selected and applied with a relatively low level of adhesive, it is difficult to maintain the adhesive force when applied to areas of high bending motion such as joints, etc. Since the polymer is used as an adhesive, there is a problem in that the solid layer is thick due to the characteristics of the product, thereby limiting the adhesive strength.

In order to solve the above problems, various attempts have been made in the art, and as a result, the patch is fixed using a bandage or a bandage after the patch is applied, or a dedicated adhesive reinforcing tape is laminated as an accessory. It is also devised to produce a product by reinforcing so that the poultice agent is not detached or by combining the adhesive reinforcing tape in part or all parts of the poultice agent in advance. In addition, it is attempting to prevent the detachment phenomenon due to bending by selecting the elastic nonwoven fabric or woven fabric as a base material, but there is insufficient point to achieve the intended purpose.

Therefore, these conventional poultices are not only inconvenient to use, but also a cost increase of the product by using the bandages, bandages, and special adhesive reinforcing tapes, and in the case of combining the poultices and adhesive reinforcing tapes, Mechanisms and complexities that require complex processes do not reduce costs. For example, Japanese Patent Application Laid-open No. 3-35160 proposes a method of combining a poultice agent and a tape for adhesive reinforcement, but a part of the poultice agent containing expensive pharmaceutical ingredients must be discarded and discarded during the Tomson punching process, which is one of essential steps. As a result, there is a problem that the cost is increased by causing the loss of materials.

The present invention has been made in view of the above-described conventional problems, the object of which is to maintain a stable adhesive state without detachment of the end during use, and can be easily detached without pain or skin damage even when removed, It is to provide a method for producing a poultice agent is easy to manufacture not only excellent productivity but also very low production cost.

Another object of the present invention is to provide a poultice which is prepared by the above production method, there is no detachment of the end part during use, and can be easily detached without pain or skin damage upon removal.

Hereinafter, a method for preparing a poultice agent and a poultice agent according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described.

The method for manufacturing a poultice agent according to the present invention includes a first adhesive coating step 100, a second adhesive coating step 110, a protective film laminating step 120, and a cutting and packing step 130.

In the first adhesive coating step 100, the first adhesive layer 12 is formed by applying the first adhesive agent on a surface of the substrate 11 except a predetermined width of both ends at a predetermined thickness.

The base material 11 is flexible, such as a woven fabric, a nonwoven fabric, and can be wound on a roll, which is convenient for continuous manufacture.

The first adhesive is the basis of the poultice agent 10 according to the present invention, the adhesive force and the adhesive holding power is appropriate to be used in a general poultice agent without any inconvenience caused by excessive adhesive force.

In the second adhesive coating step 110, when the first adhesive coating step 100 is completed, the second adhesive is applied to the both ends of one surface of the base material 11 on which the first adhesive is not applied to each other by a predetermined thickness. The two adhesive layer 13 is formed.

The second adhesive agent as the adhesive force and the adhesive holding force is strengthened than the first adhesive agent in order to prevent the end of the poultice agent 10 from being detached when the poultice agent 10 is used and to maintain the adhesive state of the poultice agent 10 continuously. Any type of adhesive may be used as long as it satisfies the purpose, but the use of the hot melt adhesive and the width to which the second adhesive is applied are preferably about 5 to 20 mm.

The component of the first adhesive is a single or a mixture of an inorganic salt of polyacrylic acid or an ester thereof, an inorganic salt of modified cellulose, a gelatin, a latex of natural or synthetic rubber, polybutene, etc. And solid materials such as kaolin, talc, zinc oxide, titanium oxide, etc. may be added for the purpose of excipients, adsorbents, colorants, and the like, and glycerol, liquid sorbitol, and purified water may be added as solvents to be used in the liquid or knee phase. In addition, depending on the purpose of treatment, painkillers, stimulants, vasodilators, antihypertensives, steroids and antimicrobial agents can be added to the therapeutic effect by the patch.
