Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patch application aid used when a patch such as a poultice or tape is applied to a desired site.

BACKGROUND ART Conventionally, various patches have been distributed for the purpose of improving stiff shoulders, lumbago, muscle pain, muscle fatigue, joint pain, and the like. These patches usually consist of a support, a medicinal ingredient-containing pressure-sensitive adhesive layer provided on one side of the support, and a release sheet releasably attached to the surface of the pressure-sensitive adhesive layer. It is configured. Then, at the time of use, the release sheet is peeled off from the adhesive layer to expose the adhesive layer, which is then attached to the application site.

However, patches are generally flexible and difficult to handle, and have the problem that they tend to wrinkle when applied or when the release sheet is peeled off.

Therefore, conventionally, patches such as those described in Patent Documents 1 and 2 below have been developed. The adhesive patch described in Patent Document 1 comprises a backing, an adhesive layer containing a medicinal ingredient, and a release sheet attached to the surface of the adhesive layer. part is formed. Since the support has stretchability, the release sheet can be easily separated into two parts simply by pulling the support and the release sheet to the left and right. After dividing the release sheet into two parts, the parting part can be used as a pinched part to be pinched with fingers, thereby facilitating peeling of the release sheet and application of the patch.

4 and 5 attached to this specification show the patch described in Patent Document 2. FIG. This patch 100 is composed of a stretchable backing 110, an adhesive layer 120, and a release sheet 130, similar to the patch described in Patent Document 1. is formed with a weakened portion 140 . In addition, a tab forming sheet 150 is joined to the central portion of the release sheet 130 of this patch 100 . A weakened portion 145 is also formed on the tab forming sheet 150 , and the tab forming sheet 150 is arranged so that the weakened portion 145 overlaps with the weakened portion 140 of the release sheet 130 . In such a configuration, when the support 110 and the release sheet 130 are pulled left and right as shown in FIG. After being cut, the tab-forming sheet 150 can be used as two tabs 150a and 150b, that is, a portion to be picked, when peeling off the release sheet 130 and applying the patch 100. FIG.

Japanese Patent No. 3192333 Japanese Patent No. 5460726

In the conventional patches disclosed in Patent Documents 1 and 2, the release sheet can be divided into two parts, and the release sheet can be easily peeled off by pinching the parting part. In addition, in the case of the patch described in Patent Document 2, a grip piece is formed separately from the release sheet, so that the patch can be gripped and operated. All patches are extremely user-friendly, but there is still a demand for easier and more reliable application without wrinkles. Therefore, an object of the present invention is to provide a patch application aid suitable for a patch that can divide the release sheet of Patent Documents 1 and 2 into two parts in order to meet such demands.

To achieve the above object, the present invention provides a support, a pressure-sensitive adhesive layer provided on one surface of the support, and a release sheet releasably adhered to the pressure-sensitive adhesive layer and capable of being separated into two parts. A patch application aid for assisting the application of a patch comprising a pair of outwardly bendable gripping sheets each extending from the base plate toward the patch placement portion of the base plate and having gripping portions at the tip end portions thereof for gripping the pinched portions of the two portions of the release sheet; and holding means for temporarily holding the grip sheet in a state of being bent outward.

The gripping portion of the gripping sheet can be composed of two folded portions formed by folding the tip of the gripping sheet. In this case, the two portions of the release sheet are separated between the two folded portions. The picked portion can be pinched and gripped.

As the holding means, it is preferable to provide an adhesive portion that can temporarily hold the gripping portion by adhesive force.

It is also conceivable to provide a magnet that can temporarily hold the grip portion by magnetic force as the holding means. For example, a holding sheet extending from each edge of the gripping sheet toward the patch placement portion of the base plate may be provided, and a magnet and/or a magnetic body may be provided at the tip of the holding sheet, and the magnet may And/or a form in which a magnet and/or a magnetic body is arranged in the gripping portion of the gripping sheet so that it can be attracted to the magnetic body is conceivable.

Further, the holding means may be a belt-like body that is attached to the base plate and separable by hook-and-loop fasteners, and the belt-like body can temporarily hold the gripping sheet by pressing it against the base plate side. .

As an applicable patch, there is also the patch described in Patent Document 2 above. That is, a support, a pressure-sensitive adhesive layer provided on one surface of the support, a release sheet detachably attached to the pressure-sensitive adhesive layer and having a weakened portion for facilitating separation, and A tab forming sheet having a weakened portion arranged so as to overlap with the weakened portion of the sheet, and the left and right portions of the weakened portion function as a tab, respectively. The plaster pasting aid of the present invention can also be applied to drugs. In this case, the picking piece can be used as the part to be picked, and the picking piece is gripped by the gripping portion.

The adhesive patch application aid according to the present invention allows the adhesive patch to be applied while the release sheet is gradually peeled off while the adhesive patch is supported by the base plate. Application can be performed without forming wrinkles.

In addition, since it has a simple structure and can be made from paper or plastic, it is inexpensive, lightweight, and easy to operate.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of an adhesive patch application aid according to the present invention will be described in detail below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and detailed description thereof will be omitted.

1 to 3 show a patch application aid 10 according to one embodiment of the present invention. This auxiliary device 10 is used for a type of patch 100 having grip pieces 150a and 150b, such as the patch shown in Patent Document 1 and FIGS. 4 and 5 attached to this specification.

As shown in FIG. 1, the patch application aid 10 includes a preferably rectangular base plate 12 having a patch placement section on which the patch 100 is placed and held. The patch placement part is the area surrounded by the dashed line 14 in FIG. In addition, the adhesive patch placement portion 14 is positioned equidistantly from a pair of mutually opposing end edges (edges along the short sides) of the base plate 12 and from a pair of mutually opposing side edges (edges along the long sides). placed equidistant.

Since the base plate 12 has both the function of holding the patch 100 flat and the function of a pressing plate for pressing the patch 100 against the desired site of the user's body, a certain degree of rigidity is required. On the other hand, the base plate 12 also needs to have a certain degree of flexibility or elasticity so that it can fit the contours of the user's body when pressed against it. For this reason, the base plate 12 is preferably made of a bendable cardboard, plastic sheet, or the like.

Gripping sheets 16 extend in the direction (inward) toward the patch mounting portion 14 of the base plate 12 from the left and right edges of the base plate 12 , and the tip of the gripping sheet 16 extends along the center line A of the base plate 12 . has reached Each gripping sheet 16 grips the corresponding tabs 150a and 150b of the patch 100 with gripping portions 18 provided at the tip thereof, and peels off the tabs 150a and 150b from the center line A of the base plate 12 and the tabs 150a and 150b integrally therewith. It is for pulling the sheet 130 outward. The gripping sheet 16 is more flexible than the base plate 12 so that when the gripping pieces 150a, 150b are gripped and pulled, no return force is generated in the gripping sheet 16 (if any, only a small return force is generated). is required, and is preferably made of thin paper, plastic sheet, or the like.

1 to 3, the gripping sheet 16 is shown as a separate member from the base plate 12, and the gripping sheet 16 is assumed to be joined to the edge portion of the base plate 12 by adhesive or heat sealing. However, if it is possible to change the characteristics such as flexibility in the same plate-like body, one plate-like body is bent and the gripping sheet 16 is continuously provided at the end of the base plate 12. can also be

In the illustrated embodiment, the gripping portion 18 of each gripping sheet 16 includes a first bent portion 18a formed by bending the tip portion of the gripping sheet 16 outward, and the tip portion of the first bent portion 18a. A second bent portion 18b is formed by bending inward, and gripping pieces 150a and 150b are held between the first bent portion 18a and the second bent portion 18b. It is possible to do so.

Gripping is performed by pinching the first and second bent portions 18a and 18b with fingers. It is also effective to provide the holding portion 18 with an adhesive portion 19 for adhering the . The adhesive portion 19 is the surface of the second bent portion 18b facing the first bent portion 18a and/or the surface of the first bent portion 18a facing the second bent portion 18b. It is preferably provided on the surface, and can be formed by applying an adhesive or attaching an adhesive tape to an appropriate portion of the surface.

It is possible to form the gripping portion 18 by folding the gripping sheet 16 as described above.

The adhesive patch application aid 10 further comprises holding means for temporarily holding the gripping pieces 150a and 150b gripped by the gripping portion 18 of the gripping sheet 16 and the release sheet 130 integrated therewith together with the gripping portion 18. .

In the illustrated embodiment, the retaining means comprises a retaining sheet 20 joined to each edge of each gripping sheet 16 and extending therefrom toward the leading edge of the gripping sheet 16, and the leading edge of the retaining sheet 20 facing outward. and a holding bent portion 22 formed by bending. Each holding bent portion 22 is positioned near the edge on the same side of patch placement portion 14 . An adhesive portion 24 is provided on the surface of the holding bent portion 22 . The adhesive portion 24 may be one to which an adhesive is applied or an adhesive tape is attached. It can be held temporarily.

Since the holding sheet 20 grips and pulls the tabs 150a and 150b in the same way as the gripping sheet 16, no return force is generated in the holding sheet 20 (even if it is generated, only a small return force is generated). It must be flexible and is preferably made of the same type of thin paper or plastic sheet as the gripping sheet 16 .

In the illustrated embodiment, the holding sheet 20 is joined to the gripping sheet 16. Alternatively, one sheet material may be folded and the holding sheet 20 may be connected to the edge of the gripping sheet 16. good.

Next, the operation and usage of the adhesive patch application aid 10 configured as described above will be described.

First, as shown in FIG. 3A, the patch 100 is placed on the patch placement portion 14 of the base plate 12 with the tabs 150a and 150b facing upward. The patch 100 is covered. As a result, patch 100 is sandwiched between base plate 12 and gripping sheet 16 . Therefore, an adhesive tape or an adhesive for temporarily fixing the patch 100 to the patch placement portion 14, or an anti-slip or the like to prevent the base plate 12 from slipping down when the base plate 12 is tilted may be provided. Although it is good, the patch 100 can be sufficiently held on the patch placement portion 14 even if it is not provided.

Next, by holding the gripping portions 18 of the left and right gripping sheets 16, that is, the first folded portion 18a and the second folded portion 18b, the corresponding tabs 150a and 150b of the adhesive patch 100 are folded over the folded portions 18a. , 18b. Then, while maintaining this gripping state, the gripping portion 18 is pulled left and right along with the tabs 150a and 150b to separate the release sheet 130 and the tab forming sheet 150 from the weakened portions 140 and 145. FIG. At this time, as shown in FIG. 3(b), gripping is performed by the force of the fingers. When the adhesive portion 19 is provided, the gripping pieces 150a and 150b can be gripped more easily with the aid of the adhesive force. can be certain. In order to prevent the gripping pieces 150a and 150b from slipping between the first and second bent portions 18a and 18b, suitable non-slip means, for example, rubber is provided on the facing surfaces of the first and second bent portions 18a and 18b. If means such as providing an adhesive, an adhesive tape, embossing, or using so-called rough paper having a rough surface, the grip can be further ensured.

Of course, as shown in FIG. 5, the left and right sides of the patch 100 are pulled outward in advance, and the release sheet 130 and the tab forming sheet 150 are separated from the weakened portions 140 and 145. Then, the patch 100 is attached to the base plate 12. The patch 100 may be covered with the left and right gripping sheets 16 by being placed on the patch placement portion 14 (FIG. 3(a)). When the release sheet 130 and the tab forming sheet 150 are separated in advance in this way, it is necessary to grip the tabs 150a and 150b with the gripping section 18 and then pull the gripping section 18 with a strong force to separate them. no.

Once the gripping pieces 150a and 150b are gripped by the gripping portion 18, the gripping portion 18 is moved outward. As a result, the grip sheet 16 is curved outward, and at the same time, the release sheet 130 is peeled off from the adhesive layer 120 of the adhesive patch 100 . Also at this time, since the patch 100 is held on the base plate 12 by a part of the grip sheet 16, the patch does not move and wrinkles do not occur.

When the gripping portion 18 reaches the holding bent portion 22 of the corresponding holding sheet 20, the gripping portion 18 is brought into contact with the holding bent portion 22 (FIG. 3(c)). As a result, the adhesive portion 24 on the holding bent portion 22 comes into contact with the first bent portion 18a of the grip portion 18, the grip portion 18 is temporarily held by the adhesive force of the adhesive portion 24, and the adhesive patch 100 is peeled off. A portion of the seat 130 is maintained in an open state. In this state, part of the adhesive layer 120 of the patch 100 is exposed to the outside between the left and right gripping sheets 16 . In addition, since a part of the gripping sheet 16 has a shape in which the edge of the patch 100 is pressed, the patch 100 does not remain even if the finger is removed from the gripping portion 18 and the patch application aid 10 is moved. It does not move from the placement section 14 .

After that, the user applies the patch so that the exposed portion of the adhesive layer 120 of the patch 100 is in contact with a desired part of the body 28, such as the back or waist, in the manner shown in FIG. 3(d). to move the support tool 10. Then, when the first and second bent portions and the temporary holding bent portion are pinched with fingers and slightly pulled in the direction of the body 28 (arrow in FIG. 3(d)), they are pulled left and right. Since the gripping pieces 150a and 150b are gripped between the first and second bent portions 18a and 18b, the patch 100 is applied to desired sites while the release sheet 130 is peeled off. During this time, the adhesive patch 100 maintains a wrinkle-free state on the base plate 12, so that the adhesive patch 100 is clean without wrinkles even after being attached. Of course, after the release sheet 130 of the patch 100 is completely peeled off from the base plate 12, the grip sheet 16 can be manipulated to affix the patch 100 to a desired site on the body. The original method of using the adhesive patch application aid 10 of the illustrated embodiment, in which the adhesive is applied while being exposed, enables reliable application without wrinkles. Furthermore, since the base plate 12 is pressed against the body, the adhesive layer 120 of the patch 100 is firmly attached to the body.

Finally, when the patch application aid 10 is removed from the user's body, the patch 100 remains on the user's skin.

Although the preferred embodiments of the present invention have been described in detail above, it goes without saying that the present invention is not limited to the above embodiments.

For example, the overall shape of the adhesive patch application aid 10 or the shape of each part is not limited to the illustrated embodiment.

Regarding the gripping portion 18 of the gripping sheet 16, it is preferable to provide the adhesive portion 19 as described above in order to increase the gripping force of the gripping portion 18. Alternatively, it is also conceivable to use magnets. For example, it is possible to provide a magnet and a magnet or a magnetic body to be attracted to each of the facing surfaces of the first bent portion 18a and the second bent portion 18b, and use this as an assisting force for gripping. .

In the above embodiment, the holding means for temporarily holding the gripping sheet 16 is composed of the adhesive portion 24 formed in the holding bent portion 22 of the holding sheet 20. Instead, it may be provided on the surface of the grip portion 18 in contact with the holding bent portion 22 . It is also conceivable to provide the adhesive portion near the edge of the gripping sheet 16 without providing the holding sheet 20 .

A magnet may be used instead of the adhesive portion 24 as the holding means. For example, a magnet is placed on the surface or inside of the holding bent portion 22, and correspondingly, on the surface or inside of the second bent portion 18b of the gripping sheet 16, or on the first bent portion 18a. Magnets may be provided on the surface or inside, and these magnets may be configured to attract each other. Temporary retention is possible even if one of these magnets is not a magnet but a mere magnetic body. Furthermore, without providing the holding sheet 20, a magnet may be arranged in the vicinity of the edge of the gripping sheet 16, and the magnet of the gripping portion 18 of the gripping sheet 16 may simply be attracted to the magnet.

Further, by arranging a pair of fastener portions of the hook-and-loop fastener on the holding portion 18 and the holding bent portion 22, respectively, it is possible to use holding means for temporarily holding the holding portion. Again, rather than retaining sheet 20, one fastener portion of the hook-and-loop fastener can be positioned near the edge of gripping sheet 16 and releasably engaged therewith with the other fastener portion of gripping portion 18. is.

Further, as shown in FIG. 6, a detachable strip 32 having a hook-and-loop fastener 30 at the tip thereof is provided on the base plate 12 as a holding means, and the strip 32 temporarily holds the gripping sheet 16 . It can be a thing. Also in this case, the holding sheet 20 is not required.

Also, the adhesive patch application aid 10 according to the present invention can be applied to the adhesive patch 100 as long as it has knobs 150a and 150b. For example, various knobs as shown in FIG. It can also be applied to the adhesive patch 100 having.

Furthermore, the patch of the present invention can also be applied to a type of patch that does not have the tabs 150a and 150b formed, such as a patch having only a release sheet without a tab forming sheet, such as the patch described in Patent Document 1 above. It is possible to apply an aid 10 for use. In this case, after the release sheet is divided into two parts by pulling the support and the release sheet to the left and right, the part near the dividing line between the two parts is used as the part to be pinched with the fingers, and this The picked part is gripped.

In addition, the adhesive patch application aid 10 of the present invention can also be applied to adhesive patches such as those described in Japanese Patent Application Laid-Open No. 2000-219622. This patch has a form in which the release sheet is divided into two parts, and one release sheet part covers the edge of the other release sheet part. This covered portion can be gripped by the gripping portion 18 as a portion to be picked. Also, the edges of the covered release sheet portion are folded back and can also be gripped by gripper 18 . Therefore, the patch can be applied by a method substantially similar to the method of use described above. There are some patches in which the edges of the covered release sheet portion are not folded back, but it goes without saying that the patch application aid 10 of the present invention can also be applied to such patches. Nor.
