Description

  The present invention relates to a device for a release liner of a patch such as a plaster agent or a shipping agent.

  Most of the contrivances of the conventional release liner have the purpose of facilitating sticking with both hands. For example, a patch (for example, Patent Document 1) that makes it easy to peel off the release liner using a cut portion obtained by cutting the release liner at the center of the patch as a waveform, and a peeling operation of the release sheet and an application operation of the patch to the affected area In order to perform simultaneously, the patch which cut | disconnects the cut | interruption part formed in the release sheet with both hands with the specific condition of the bending softness of the release sheet with both hands, and sticks to an affected part (for example, patent document 2) Etc.

  Moreover, in the patch, there are not a few cases where the affected part is a part that cannot be attached using both hands such as the elbow, arm, shoulder, and waist. In this case, it was not possible to paste it by yourself, and it was necessary to borrow another person's hand. Therefore, a patch having a band for hooking a finger on a support opposite to the base material of the patch has been proposed (see, for example, Patent Document 3).

Japanese Utility Model Publication No. 5-85825 JP 2001-335471 A Japanese Utility Model Publication No. 6-11718

  Regarding the proposal of a patch provided with a band for hooking a finger on the support opposite to the base material of this patch, “How to fasten the band can be done in various ways, such as using an adhesive or sewing.” 3, Paragraph No. 0007) ", but in the case of sewing, it is obvious that it is not suitable for mass production because it is necessary to sew the support and the band in each patch. It is.

  In addition, when using an adhesive, new components are added to the conventional patch, so there are problems such as the expansion of the patch production line, price, and safety in order to keep mass production in mind. is there. Specifically, although not in direct contact with the skin, there are problems such as safety problems such as a solvent contained in the adhesive and verification of adverse effects of the adhesive on the base material components.

  In recent years, not only living alone of young people including students but also living alone of single employees and elderly people are increasing, and a patch that can be applied with one hand is anxious. Therefore, the present invention proposes a configuration of a patch that can be pasted with one hand, which can be mass-produced at low cost without greatly changing the conventional production line of the patch.

A patch according to the invention described in claim 1 includes a rectangular patch body having a long side and a short side , wherein a plaster layer to which a medicinal component is added is formed on one surface of the support, and the patch. In a patch provided with a release liner covering the plaster layer surface of the agent body,
The release liner is a flexible film-like body ,
In the release liner,
A cutting line formed between the long sides facing one end of the short side of the liner and dividing the liner into two;
It is formed in a substantially central portion of the liner, and is provided with a substantially U-shaped slit that is not cut in one side on the cutting line side and is cut in the other three directions. is there.

The patch according to the invention described in claim 2 is characterized in that the slit according to claim 1 is sized to allow any one or more of the index finger, middle finger, and ring finger to be inserted. Is.

In the patch according to the invention described in claim 3 , two or three slits according to claim 1 that allow the insertion of any one of the index finger, the middle finger, and the ring finger are formed. It is characterized by this.

  As described above, the present invention has an effect that it is possible to obtain a patch that can be pasted with one hand and can be mass-produced at low cost without significantly changing the conventional patch production line.

  In the present invention, a flexible film in a patch comprising a patch body having a plaster layer formed on one surface of a support and a release liner covering the paste layer surface of the patch body. Since a slit is formed in the substantially central part of the release liner, which is a body, when the one end of this liner is bent toward the other end, it becomes a finger hole. It is possible to obtain an adhesive patch that can be applied with one hand without greatly changing the production line of the adhesive and capable of mass production at low cost.

  The patch of the present invention may be any one provided with a support, a plaster layer formed on one surface of the support, and a release liner covering the surface of the plaster layer, such as a plaster agent and a shipping agent. It is a dosage form.

  The plaster layer of the patch of the present invention may be any layer as long as it is applied to the skin and percutaneously absorbs the medicinal component into the affixed part to improve the affected part, and the medicinal layer itself contains an adhesive component. May also be included, but those containing an adhesive component are advantageous for sticking. In addition, specific examples of medicinal ingredients include the following.

  For example, anti-inflammatory analgesic ingredients include methyl salicylate, glycol salicylate, menthol, camphor, indomethacin, ketoprofen, flurbiprofen, diclofenac sodium, flufenamic acid, piroxicam, etc. Herbal medicine ingredients such as Examples of the blood circulation promoter component include tocopherol acetate, nonyl acid vanillylamide, and pepper extract. It should be noted that, for systemic substances such as steroidal anti-inflammatory agents, vasodilators, hormone agents, bronchodilators, etc., it is not always necessary to use one hand, but it is useful if it can be easily applied. Other examples include local anesthetics; antispasmodic agents; emollients.

  The addition amount of the medicinal component varies depending on the type of medicinal component and is appropriately determined depending on other compositions such as the adhesive component, but is usually preferably 0.01 to 30% by weight in the composition constituting the plaster layer. The medicinal component is added to the plaster layer at a concentration as close as possible to the saturation solubility, and high release is obtained by preventing crystal precipitation.

  The release liner of the present invention is not particularly limited as long as it does not leave the plaster layer remaining on the liner when it is peeled off, and can be peeled off from the plaster layer satisfactorily. As a material for the release liner, for example, paper, synthetic paper, polyethylene, polypropylene, polyester, polystyrene, and a laminated film obtained by bonding them together are preferably used.

  Further, the thickness of the release liner is not particularly limited as long as it has flexibility, but when one end of the release liner is peeled off and folded outward to the opposite other end, the release liner has a substantially central portion. The formed slit opens naturally, and when the adhesive is put through the finger in the hole of the cut, it does not sag so that the other end attached to the liner supports both sides with the thumb and other fingers The thickness is as follows. For example, it is 10 to 100 μm, and more preferably 30 to 50 μm. Furthermore, the surface of the plaster side that has been subjected to silicon treatment, the embossed surface, or the one that has been colored and / or printed so that there is no remaining plaster can be used.

  The slit used as the finger hole of this invention should just be a structure which naturally opens when the one end side of a peeling liner is bent to the other end side, and becomes a finger hole. Specifically, an annular slit may be used, but in this case, it is necessary to devise a technique in which the liner inside the annular slit does not remain on the plaster layer surface when the release liner is peeled about halfway. Therefore, as a non-annular slit, when the release liner is peeled about half, the liner does not remain on the plaster layer surface. More specifically, by forming a substantially U-shaped slit, even when the release liner is peeled about half, no part of the liner remains on the surface of the plaster layer, and one end side of the release liner is on the other end side. When it is bent, it opens naturally and becomes a finger hole.

  Preferably, the substantially U-shaped slit is arranged so that no cut is made on one side to be peeled first, and the other three sides are cut so that there is no resistance when the liner is peeled off for the hole through which the finger passes. And Further, the corners of the slit may be rounded or the tip of the slit may be directed inward so as not to be broken when the finger is put in and pressed or the liner is peeled off by pulling. Furthermore, in order to make it easy for the user to determine how many fingers are inserted, the shape is such that a plurality of circles or ellipses overlap or a protrusion is projected inside the hole to fit between the fingers. Good. A plurality of substantially U-shaped slits can be provided so that the number of fingers can be clearly understood. In this case, the guidance for inserting a finger is rich in suggestions, but since there is no flexibility in the size of the finger, any patch that is intended for use and limited by the user is useful.

  Therefore, as a preferable aspect, the slit that becomes the finger hole of the present invention has a size that allows any one or more of the index finger, the middle finger, and the ring finger to be inserted. This is because when the adhesive body with the release liner half peeled is joined together on the support side, both sides of the plaster layer, which is on the lower side, are next to the thumb and the finger next to the finger placed in the hole (middle finger, This is because it is necessary to support with the ring finger, little finger, etc.). Furthermore, as another preferred embodiment, two or three slits that allow insertion of any of the index finger, the middle finger, and the ring finger are formed as the slits serving as the finger-through holes of the present invention. This is not the best because the size and shape of the finger differs depending on the user, but there is a suggestive advantage as motivation to put the finger in and apply it.

  When this patch is applied with one hand, the plaster layer of the patch body is peeled from the release liner by about half from one end side to the other end side, and the patch body is combined with the support side. At that time, a slit formed in a substantially central portion of the release liner appears. Since the release liner is flexible, if one end of the side from which the plaster layer is peeled is bent to the opposite side to the side of the patch body, the slit becomes a finger hole, and the index finger extends from this hole. And / or the other finger (middle finger, ring finger), one to three in total, is inserted according to the size of the patch or own finger. The sides of the plaster layer, which are half peeled and the support sides are combined, are supported by the thumb and the finger next to the finger placed in the hole (ringing finger, little finger, etc.). When the liner side and the plaster layer side are sandwiched with one hand, apply the plaster layer to the affected area, hold it well with the finger put in from the hole, and if it is pulled as it is, the liner will easily peel off, The plaster surface can be applied to the entire affected area, and the patch can be applied with one hand.

  Therefore, by being able to stick with one hand, not only the part to stick by yourself becomes wide, but also at the time of sticking, the product is almost folded in half with your fingers, compact and by controlling the adhesive surface with your fingers, The shoulder, waist, etc. can also be affixed from the gap between the underwear without changing the clothes.

  If the slit that is the finger hole of this patch is located at the approximate center of the release liner, it appears when the paste layer of the patch body is peeled about half from the release liner, and the subsequent application operation is smooth. It can be carried out. In many cases, the patch body has a rectangular shape having a long side and a short side. Therefore, in order to smoothly perform the sticking operation, the release liner is preferably arranged so that one short side is aligned with the other short side. A slit is arranged in such a direction that a finger hole appears when the half is peeled off.

  When this patch is applied with one hand, the plaster layer of the patch body is peeled from the release liner by about half from one end side to the other end side, and the patch body is matched on the support side, as a preferred embodiment. Is a cutting line that divides the liner on one end side of the release liner. For this reason, not only is it easy to peel off one end side of the release liner, but it is divided when the patch layer of the patch body is peeled about half way from one end side to the other end side, and the patch body is joined together on the support side. Further, the support liners can easily match with each other without twisting by the release liner on one end side.

  Furthermore, even when sticking with both hands, it is possible to easily expose the plaster layer surface of the patch body by the cutting line of the release liner. The cutting line can be devised such as a broken line, a wavy line, and a plurality of cuts cut into a wavy line and / or a broken line leaving a joint, as in a conventional patch.

  As described above, the patch of the present invention has the conventional idea of applying with both hands, and can be applied with one hand by providing a slit in the hole through which a finger passes through the liner. Furthermore, since only the release liner is changed from the conventional patch, the production line is not significantly changed, and mass production is possible at low cost.

  In the production of the patch of the present invention, the slit to be a finger hole may be formed on the release liner before or after the release liner is integrated with the plaster layer surface. That is, a slit that becomes a finger hole is formed in the release liner in advance, and then the plaster layer is coated to form a cutting line that divides the liner. A slit may be formed.

  As described above, according to the present invention, a patch that is required to be applied with one hand, that is, a patch that is so small that a hole for inserting a finger is impossible, and a large-size patch that cannot be supported by five fingers of one hand. It can be applied to patches with all liners except the agent.

  FIG. 1 is an explanatory view showing the structure of one embodiment of the patch of the present invention, wherein a is a plan view and b is a front view. As shown in the figure, the patch of the present invention comprises a patch body 10 having a plaster layer 12 formed on one surface of a support 11 and a release liner 13 covering the surface of the patch body 12 of the patch body 10. Prepare. A substantially U-shaped slit 14 and a broken line-shaped cutting line 15 that divides the release liner 13 into two are formed at a substantially central portion of the release liner 13.

  The release liner 13 is a polyethylene film having a thickness of 50 μm, and has flexibility enough to bend without breaking due to the weight of the patch itself. The slit 14 has a substantially U-shape with no cuts on one side on the cutting line 15 side and cuts on the other three sides. The corner of the slit is rounded and the tip of the slit is It is formed toward the inside.

  FIG. 2 is an explanatory view showing each step of applying the patch of FIG. When this patch is applied with one hand, as shown in FIG. A, the small area divided by the cutting line 15 is peeled off about half from the release liner 13, and the patch body 10 is supported as shown in FIG. Match with the body 11 side comrades. At that time, a slit 14 formed in a substantially central portion of the release liner 13 appears. Since the release liner 13 has flexibility, when the one end side on the side where the plaster layer 12 is peeled is bent to the other end side opposite to the patch body 10, the slit 14 opens naturally, and the finger It becomes a through hole.

  As shown in FIG. c, since the finger passage hole 16 is large enough to pass two fingers, the index finger 22 and the middle finger 23 are inserted into the hole 16. At this time, both sides of the plaster layer surface half peeled are supported by the thumb 21 and the ring finger 24 adjacent to the finger placed in the hole 16. When the liner 13 side and the plaster layer 12 side are sandwiched with one hand, the release liner 13 on the small area side is removed as shown in FIG. As shown in Fig. e, after the plaster layer 12 is applied to the affected area 17 and restrained with a finger inserted through the hole 16, the liner 13 is easily peeled off by pulling forward as shown in Fig. f. As described above, the plaster surface 12 can be attached to the affected part 17 as a whole, and the patch body 10 can be attached with one hand.

  FIG. 3 is an explanatory view showing a plan configuration of another embodiment of the patch of the present invention, wherein FIG. 3a is for three fingers, and FIG. B is for two fingers. FIG. 4 is an explanatory view showing a plan configuration of still another embodiment of the patch of the present invention, wherein FIG. 4a is for 3 fingers and FIG. 4b is for 2 fingers. FIG. 5 is an explanatory view showing a plan configuration of still another embodiment of the patch of the present invention. FIG. 5a is for three fingers, FIG. B is for two fingers, and FIG. C is for one finger. FIG. 6 is an explanatory view showing a plan configuration of still another embodiment of the patch of the present invention, in which a figure is for three fingers, b figure is for two fingers, and c figure is for one finger. FIG. 7 is an explanatory view showing another pattern of slits to be finger through holes of the release liner of the patch of the present invention.

  As shown in FIG. 3 to FIG. 7, the slit that becomes the finger passage hole of the patch of the present invention has a structure that naturally opens when the one end side of the release liner is bent toward the other end side to become the finger passage hole. I just need it. Although there are various shapes and sizes other than those shown in FIG. 1, they are basically substantially U-shaped.

  For example, the release liners 33a and 33b covering the plaster layer of the patch body in FIGS. 3a and 3b are not cut on one side on the side of the cutting lines 35a and b, and the other three sides Slits 34a and 34b are formed, and three slits and two circles are cut out on the side of the slits 34a and b facing the cutting lines 35a and b, and three users are cut. It is possible to easily determine whether to insert a finger or two fingers.

  In order to suggest that the user inserts three fingers and two fingers, two or three slits that serve as finger-through holes may be formed. Specifically, the release liners 43a and 43b covering the plaster layer of the patch body in FIGS. 4a and 4b are not cut on one side on the side of the cutting lines 45a and b. Two or three slits 44a and 44b cut in three directions are formed.

  The idea for suggesting that the user inserts three to one finger is the same as in FIGS. 5 and 6, and the release liners 53 and 63 have cutting lines 55 and 65 and slits 54 and 64. 3 may be formed, and projections 57 and 67 may be attached to portions corresponding to portions between fingers inserted into the slits 54 and 64 instead of the plurality of circles of FIG.

Moreover, the shape of the cutting line can be devised such as a broken line, a wavy line, a plurality of cuts that are cut into a wavy line and / or a broken line leaving a joint, as in a conventional patch, Further, it may be formed so as to engage with the finger hole. For example, it is good also as a several cut | disconnection cut | disconnected by the polygonal line shape as shown in the c figure of FIG. 7, and d figure .
