《Patent Issued for Pressure-Sensitive Adhesive Tape Package》：
By a News Reporter-Staff News Editor at Journal of Engineering — According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Miyachi, Isao (Tosu, JP); Takano, Yuichi (Tosu, JP); Tsunoda, Hiromitsu (Tosu, JP), filed onDecember 14, 2009, was published online on December 31, 2013.
The assignee for this patent, patent number 8616371, is Hisamitsu Pharmaceutical Co., Ltd. (Tosu-Shi, Saga, JP).
Reporters obtained the following quote from the background information supplied by the inventors: “Adhesive tapes in a variety of forms have conventionally been known and used for labels, medical care, cosmetics, decoration, masking, electronic industries, and other various applications. The adhesive tape used for medical care is in a form of a patch preparation such as a poultice, a plaster, and a surgical tape, and usually applied onto a skin, a mucous membrane, or the like.
“Such an adhesive tape usually comprises an adhesive tape having a support and an adhesive agent layer provided on one surface of the support, and a release sheet releasably attached to the adhesive agent layer. The adhesive tape, after production, may be cut into an appropriate size and distributed and sold in the state of being individually contained in a package for hygienic and physical protection. In this case, at the time of use thereof, the adhesive agent layer is applied onto a portion for application after tearing the package to remove the adhesive tape therefrom, and release the release sheet to expose the adhesive agent layer.
“A problem that often occurs at the time of use is difficulties in releasing the release sheet. Because the release sheet is usually thin and soft, it is difficult to handle, and it may take some time to release the release sheet. In order to improve this point, for example, as disclosed in Japanese Patent Application Laid-Open Publication Nos. 2007-75602 and 2007-75601, Japanese Patent No. 3689807, Japanese Utility Model Laid-Open No. 50-133797, or the like, a variety of release sheets and adhesive tapes have been developed in which easiness in releasing the release sheet and easiness in applying the adhesive tape are pursued.
“Each of these release sheets or adhesive tapes has a structure such that convenience is pursued from the viewpoint of easiness in applying the adhesive tape. It is certainly convenient, but there is no difference in that the adhesive tape maintains the form including the release sheet and the package, and the release sheet and the package are turned into a waste after use.
“An object of the present invention is to provide an adhesive tape with which easiness in applying the adhesive tape is pursued while an effect of saving in resources can be obtained.”
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors’ summary information for this patent: “In order to achieve the object, the present invention is a pressure-sensitive adhesive tape package that accommodates an adhesive tape having a support and an adhesive agent layer provided on one surface of the support, the pressure-sensitive adhesive tape package comprising a release sheet releasably attached to the adhesive agent layer, wherein the release sheet is bent into a first portion and a second portion along a predetermined first bending line, the adhesive tape is bent into a first portion and a second portion along a predetermined second bending line such that the adhesive agent layer faces outwardly, and the bent adhesive tape is sealed inside of the bent release sheet. With such a configuration, the conventionally existing package can be eliminated. Moreover, when the release sheet is opened while being released from the adhesive agent layer of the adhesive tape, a half of the adhesive agent layer is exposed; accordingly, application of the adhesive tape to a portion for application is easy. It is preferable that the adhesive tape is sealed inside of the bent release sheet in the state where the first bending line and the second bending line are adjacent to each other (see FIG. 1), but the directions of the first and second bending lines are not limited to this; the first bending line and the second bending line may be arranged opposed to each other (see FIG. 14).
“It is preferable that the first portion of the release sheet is substantially in the same shape as that of the second portion of the release sheet, the first portion and the second portion of the release sheet are superimposed, and a portion surrounding the adhesive tape in which the first portion and the second portion of the release sheet are superimposed is sealed. Because the inside is isolated from the outside by sealing the release sheet, the adhesive tape is protected more hygienically and physically, no component of the adhesive agent layer of the adhesive tape is leaked to the outside.
“It is also effective that at least one projecting point projecting outward is formed in an outer edge of a face-to-face joint portion joining the first portion of the release sheet to the second portion of the release sheet in a face-to-face relationship to seal therebetween. Because a force concentrates on this projecting point at the time of opening, the face-to-face joint starts breaking from the projecting point to facilitate opening.
“It is preferable that a non-bonded portion as a holding portion for opening is provided between the first portion and the second portion of the release sheet. Moreover, in the case where a mark that can be recognized by touch, like a notch, is provided in the non-bonded portion of one of the first portion and the second portion of the release sheet, even a visually impaired person can easily figure out the direction of the adhesive agent layer of the adhesive tape to be exposed. It is described as ‘one of the first portion and the second portion of the release sheet,’ and it should be understood that this involves the case where the different kinds of marks are provided in both of the first portion and the second portion thereof, for example, one notch in the first portion of the release sheet and two notches in the second portion.
“It is preferable that means for reducing an adhesive force that reduces an adhesive force between the adhesive agent layer of the first portion of the adhesive tape and the release sheet is provided on at least a part of the release sheet. This is because application to the portion for application is easy as the adhesive agent layer is easily released from the release sheet to expose the adhesive surface when the release sheet is opened.
“The material and configuration of the release sheet is not particularly limited as long as the adhesive layer of the adhesive tape can be protected until the adhesive tape is used, but the configuration in which a cellophane film, a plastic film, and an aluminum foil from the outer layer and further a plastic film in the inner layer are laminated is preferable; further, it is preferable that the means for reducing an adhesive force is a silicone-treated surface provided on at least a part of a portion of the release sheet that is applied to the adhesive agent layer of the first portion of the adhesive tape. Among a variety of means for reducing an adhesive force, the silicone treatment is advantageous in that the treatment is performed relatively easily and at low cost. As another means for reducing an adhesive force, embossing and/or sanding may be performed on the portion.
“As other means for easily releasing the release sheet from the adhesive agent layer of the adhesive tape, in a portion of the release sheet that is the second portion of the adhesive tape in which the first portion of the adhesive tape is larger than the second portion of the adhesive tape, and has an extending portion that extends from the second portion, a temporary attaching means may be provided in at least a part of a portion facing the extending portion in a portion of the release sheet on the second portion side of the adhesive tape. It is preferable that an adhesive force of the support of the adhesive tape to the release sheet through the temporary attaching means is larger than an adhesive force of the adhesive agent layer to the release sheet. As the temporary attaching means, an adhesive agent, namely, those having adhesiveness to the support of the adhesive tape are preferable. By providing such a temporary attaching means in the release sheet, the first portion of the adhesive tape is easily separated from the release sheet without a silicone-treated surface or the like, and it is more preferable that provision of the temporary attaching means is used in combination with the silicone-treated surface or the like.
“The first portion and the second portion of the adhesive tape may be substantially in the same shape, and the temporary attaching means may be provided between the first portion and the second portion. In this case, it is preferable that the adhesive force or attaching force of the temporary attaching means is larger than the adhesive force of the adhesive agent layer to the release sheet.
“The thus-configured pressure-sensitive adhesive tape package can apply the whole surface of the adhesive tape to the portion for application by adhering an exposed portion of the adhesive agent layer of the adhesive tape that appears at the same time when the release sheet is opened to the portion for application, and then pulling along the portion for application in the longitudinal direction of the release sheet and a direction away from the adhesive tape.”
