Description

  The present invention relates to an adhesive tape or sheet for applying a piglet for forming a double piglet, which can easily and cleanly apply a skin patch to a piglet in a short time.

  Previously, there were examples of orthopedic surgery to form a double piglet, but in recent years a method of sticking the tape on the piglet's skin and bonding the piglet's skin to a double piglet with double-sided tape In general, a method of adhering the skin of a piglet to a double piglet using an emulsion or latex is also generally performed.

  As an example of sticking the tape on the skin of the piglet, it is common to stick a horizontal tape made of cellophane film etc. on the piglet above the human eye and form a double piglet by moving the piggy up and down . In this method, there is a problem that when the tape is peeled off from the release paper, the finger touches the adhesive surface of the tape. There was also a problem that it was damaged and could not be removed cleanly. Moreover, the tape made of a material such as a cellophane film has a problem that it stands out when it is applied. The above-described method has problems such as being complicated, not easy, and requiring time.

Various studies have been made to solve the above problems. For example, a method of pasting with about half of the release paper is disclosed (Patent Document 1), but the tape curls because it holds one of the tapes by hand. And operations such as delicate positioning are not easy. Moreover, although what provided the adhesion part for positioning of the double piglet formation sheet was disclosed (patent document 2), in order to stick a positioning part to the center part of eyes, it is necessary to do carefully, looking at a mirror. Since it sticks along the shape of Mabuta, complicated operation is required and is not easy. Double-mabute forming tape consisting of a thin tape-like member that stretches elastically or can be stretched needs to be cut to an appropriate length after sticking adhesive tape or thread to mabuta There is a problem to be solved (Patent Document 3).

  The present invention does not require detailed work when peeling the mount from the skin patch material, which is a tape for pigs, and may be peeled cleanly without inadvertently folding or tearing the mount, and the skin patch material may be applied to the piglet. It is an object of the present invention to provide an adhesive tape or sheet for sticking pigs that can be easily and in a short time.

  As a result of intensive research, the inventors have devised the size of the skin patch and the size of the mount so that the mount can be easily peeled off from the skin patch. The present inventors have found that an adhesive tape or sheet for attaching piglets can be provided.

That is, this invention consists of the following.
1. The adhesive-exposed portion on one side of the double-sided adhesive skin patch (2) is laminated and bonded to the mount (1) subjected to the release treatment, and the single-sided adhesive on the upper part of the laminated skin patch (2). A self-adhesive tape or sheet for sticking pigtails, characterized in that the mount (3) is laminated, and the mount (1) and the mount (3) are longer than the skin patch (2).
2. 2. The adhesive tape or sheet for sticking pigtails according to item 1 above, wherein the mount (1) is longer than the mount (3).
3. 3. The adhesive tape or sheet for sticking pigtails according to item 1 or 2, wherein a release treatment member (7) is laminated between the skin patch (2) and a single-sided adhesive mount (3).
4). Any one of the preceding items 1 to 3, wherein the mount (1), the skin patch (2) and the mount (3) are punched and at least an end of the mount (1) is not punched. The adhesive tape or sheet for sticking Mabuta of description.

  The adhesive tape or sheet for sticking pigtails of the present invention is easy to take out from the packaging member, easily peels off the backing from the skin patch, and the skin patch is easy to stick to the skin. The effect of being difficult was obtained.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.
As shown in FIG. 1, the adhesive tape or sheet for sticking pigtails according to the present invention is composed of at least three members, a mount (1), a double-sided adhesive skin patch (2), and a mount (3). (1) It has a structure in which the skin patch (2) and the mount (3) are laminated directly or indirectly. The skin patch (2) is formed by laminating an adhesive layer (4), a base material (5), and an adhesive layer (6). The adhesive tape or sheet for applying pigeons of the present invention is punched, and the skin patch (2) is cut into a size suitable for sticking to piglets.

The method for sticking the skin patch (2) to the piglet from the adhesive tape or sheet for piglet sticking of the present invention is as follows.
First, one punched adhesive tape or sheet for sticking mabuta as shown in FIG. 3 is separated. The mount (1) is peeled off from the separated adhesive tape or sheet for sticking pigtails to expose the adhesive layer (4) on one side of the skin patch (2). Hold the both sides of the mount (3) with your hands so that your skin patch (2) is laminated with the mount (3) so that your hands do not touch the adhesive surface of the skin patch (2). Affix the exposed adhesive surface of (2) near the center of the piglet. If a double piglet can be formed by applying the skin patch (2), it may not be strictly applied to the center of the piglet. In order to make the skin patch (2) sufficiently pasted, a belly of a finger or a jig may be used as necessary. When the skin patch (2) is sufficiently pasted to the piglet, the skin patch (2) is peeled from the skin patch (2) with one end of the mount (3).

The structure of the adhesive tape or sheet for mabuta of the present invention is as follows.
The mount (1) has been subjected to release treatment, and the adhesive-exposed portion on one side of the skin patch (2) is laminated and bonded together. Further, the mount (3) is laminated directly or indirectly with the adhesive-exposed portion (6) on the other side of the skin patch (2) (see FIGS. 1 and 2). 2). For example, a release member (7) may be laminated between the skin patch (2) and the mount (3) (FIG. 2). An adhesive may be applied to the surface of the mount (3) that is directly or indirectly laminated on the skin patch (2).

With respect to the length direction shown in FIG. 3, the mounts (1) and (3) have a longer shape than the skin patch (2) (FIGS. 1 and 2). The lengths of the mounts (1) and (3) may be the same as long as they are longer than the skin patch (2), but the mount (1) is the same as the skin patch (2) and the mount (3). In consideration of peeling from the mount, it is preferable that the lengths of the mounts (1) and (3) are different, and it is more preferable that the mount (1) is longer than (3).
The length of the mount (3) is not particularly limited as long as it is longer than the skin patch (2), but after peeling the mount (1), the skin patch (2) is pasted to the piglet with both ends of the mount (3). When there is almost no difference in length between the mount (3) and the skin patch (2), the finger surface comes into contact with the adhesive surface on the side of the skin patch (2) to be applied to the skin. Adhesion to Mabuta decreases. Therefore, the difference in length between the skin patch (2) and the mount (3) is preferably at least one finger at both ends, more preferably at least two fingers.

  With regard to the width direction shown in FIG. 3, the width of the skin patch (2) is higher when it is more adhesive to the skin and more easily forms a double piglet. In order not to stand out, it is better to be as narrow as possible. From such a viewpoint, the width of the skin patch (2) is preferably 10 mm or less, more preferably 2 mm or less. The longer the length, the better the adhesiveness to the skin and the easier it is to form a double piglet. From such a viewpoint, the length of the skin patch (2) is 50 mm or less, preferably 35 mm or less. The shape of the skin patch (2) may be curved in accordance with the shape of the piglet, but if it is the size described above, even if it is rectangular, it can be sufficiently stuck to the piglet.

  In order to create an adhesive tape or sheet for attaching a piglet containing the skin patch (2) of the above size, the sheet including the laminated mount (1), the skin patch (2) and the mount (3) is Punched. For example, as shown in the left diagram of FIG. 3, the laminated sheets can be punched into the laminated surface so as to have a constant width of 10 mm or less, more preferably 2 mm or less.

By the punching process, at least the laminated skin patch (2) and mount (3) are punched out. Also, it is more convenient to use the mount (1) when it is punched.
However, if the mount (1), skin patch (2), and mount (3) are all punched out, the adhesive tapes or sheets for sticking the piglets will be scattered apart, which is inconvenient for storage. Also, it is inconvenient when taking out at the time of use.
For example, if the length of the mount (1) is longer than the length of the mount (3) and the end of the mount (3) is not punched, the individual adhesive tape or sheet for sticking the piglet will be divided when used It is inconvenient because it is not done. For example, the mount (3) is punched together with the skin patch (2), and if the end of the mount (1) is not punched, the adhesive tape or sheet for sticking the individual piglet will not be dispersed and used. The adhesive tape or sheet for sticking can be separated as many as necessary. For example, a perforation or the like may be applied to a portion of the mount (1) and / or (3) where the end is not punched to make it easy to cut.
The size of the unpunched portion and the perforation at the end of the punched mount is not particularly limited as long as it is an operable size.

  The adhesive tape or sheet for sticking pigtails of the present invention has a shape having the above-mentioned characteristics, and does not require a fine work to peel the backing (1) from the skin sticking material for piglets (2) and the backing (3), Furthermore, it can be peeled cleanly without being bent or broken carelessly, the skin patch (2) can be easily affixed to Mabuta, and the mount (3) can also be easily peeled cleanly.

The material of the adhesive tape or sheet for sticking pigtails of the present invention is as follows.
First, the base material (5) of the skin patch (2) having double-sided adhesive properties has stretchability, but does not have elastic stretchability after stretching, has stretchability, but is not stretched and used. Things can be used. For example, paper using pulp or the like, non-stretchable nonwoven fabric, or the like can be suitably used. In addition, knitted fabrics such as silk and cotton, silicone, cellophane, etc. can be used.

The adhesive layers (4) and (6) of the skin patch (2) can be rubber-based, synthetic rubber-based, acrylic-based, silicone-based, etc., and are not particularly limited, but the adhesive properties are relatively controlled. Acrylic materials that are easy and provide moisture permeability relatively easily are suitable. Furthermore, as a skin-friendly adhesive, a medical adhesive or an adhesive for skin application disclosed in Japanese Patent No. 2539330 (Japanese Patent Application No. 05-133994) or Japanese Patent Application Laid-Open No. 2002-065841 (Japanese Patent Application No. 2000-265365) is disclosed. A composition or the like can also be used.
The pressure-sensitive adhesive layers (4) and (6) having a degree of adhesion that is adjusted according to the mode of use can be used. For example, since the backing (1) is separated from the skin patch (2) and the backing (3) during use, the adhesiveness of the adhesive layer (6) may be greater than the adhesiveness of the adhesive layer (4). Is preferred.

  The mount (1) is not particularly limited as long as it is a paper or PET that has been subjected to a release treatment, or a polyolefin that exhibits low adhesion, or a paper that has been laminated with these. A known method can be adopted for the mold release treatment.

The mount (3) is required to have an appropriate tensile strength in order to attach the skin patch (2) to the piglet using the portion. Specifically, the tensile strength may be 3.0 N / 20 mm or more and the elongation may be 30% or less, and is not particularly limited, but preferably has a tensile strength of 5.0 N / 20 mm or more.
The mount (3) is preferably laminated and laminated to the skin patch (2) .In that case, the part of the mount (3) that contacts the adhesive surface of the skin patch (2) is subjected to a release treatment. It is necessary to do. Alternatively, the release member (7) can be laminated between the mount (3) and the skin patch (2) (FIG. 2). The release-treated member (7) is preferably a paper or olefin-based or polyester-based polymer material that has been subjected to a release treatment on the surface in contact with the skin patch (2). The mold release function can also be expressed using an olefin system having a low surface energy. In that case, it is necessary to consider the adhesiveness of the adhesive surface between the release-treated member (7) and the mount (3). The adhesiveness can be adjusted by a general method such as corona treatment.

  In this specification, the tensile strength of the mount (3) is 20 mm wide × 150 mm long, with a 100 mm marked line as a sample, and when the sample is pulled at a pulling speed of 300 mm / min, the fracture It was obtained by measuring the tensile strength at the time.

Table 1 shows the length of each member of the skin patch (2), the mounts (1) and (3), the cutting width, and the cutting state of the ends of the mounts (1) and (3).
The cut state is as follows (both ends of the mounts (1) and (3), with the skin patch (2) and the mounts (1) and (3) punched out)), and one end (mounts (1) and (3 ), Cut out the skin patch (2), mounts (1) and (3)), leaving all ends (cut the mount (1), skin patch (2), and mount (3) And those that fall apart).

In the Examples, the same acrylic pressure-sensitive adhesive was used for the skin patch (2), and the coating thickness after drying was unified to 80 μm.
About the adhesive tape or sheet | seat for a piglet sticking of the shape of each Example or a comparative example, the operativity at the time of taking out, the operativity at the time of sticking, a feeling of wearing, and the recognition degree at the time of sticking were evaluated.
The operability at the time of taking out refers to the operability at the time of taking out the adhesive tape or sheet for sticking the piglet used, and the operability at the time of sticking means the operability when sticking the skin patch (2) to the piglet. The feeling of wearing refers to the comfort when the skin patch (2) is applied, and the degree of recognition at the time of application refers to whether or not it is noticeable when the skin patch (2) is applied to a piglet. The evaluation points are shown in Tables 2-5.

  Using the tapes or sheets having the shapes of Examples 1 to 3 and Comparative Examples 1 to 3, the skin patch (2) was applied to the knee joints of 20 volunteers aged 30 and over, according to the following criteria: The sticking property was evaluated.

(Operability when removing)
The operability at the time of taking out was evaluated in four stages of “easy to take out”, “no problem”, “difficult to take out”, and “very difficult to take out”. Of the above-mentioned steps, “easy to take out” and “no problem” are considered effective for good operability, and the effective rate is also shown in Table 2.

(Operability when pasting)
The operability was evaluated in four levels: “easy to stick”, “no problem”, “difficult to stick”, “very difficult to stick”, and the results for the corresponding number of people are shown in Table 3. Among the above-mentioned stages, “easy to paste” and “no problem” are considered effective for good operability, and the effectiveness is shown in Table 3.

(A feeling of wearing)
The feeling of wearing was evaluated in four stages, “very comfortable”, “no problem”, “feeling uncomfortable”, and “very uncomfortable”, and the results of the corresponding number of people are shown in Table 4. Of the above-mentioned stages, “Very comfortable” and “No problem” are considered effective for good wearing feeling, and the effectiveness rate is also shown in Table 4.

(Recognition at the time of wearing)
The degree of recognition at the time of wearing was evaluated in four stages of “not noticeable”, “no problem”, “noticeable”, and “very noticeable”. Of the above-mentioned stages, “not conspicuous” and “no problem” are considered to be effective for good recognition at the time of wearing, and the effectiveness rate is also shown in Table 5.

  As described above, the adhesive tape for sticking pigtails of the present invention is easy to take out from the packaging member, easy to peel the skin patch from the mount, and easy to stick the skin patch, and is comfortable when the skin patch is attached. The effect of being inconspicuous is obtained and a double piglet can be easily formed.
