A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

An adhesive anti-slip pad for placement on the finger, thumb, or palm of a wearer. The adhesive anti-slip includes a first side having a first surface comprising a textured material and a second side having a second surface comprising an adhesive. The adhesive anti-slip pad is configured to be placed on a thumb, finger, or a palm of the wearer. The adhesive anti-slip pad further comprises a thickness so that if the adhesive anti-slip pad contacts the surface of another object after placement of the adhesive anti-slip pad on the thumb, finger, or palm, the wearer receives a tactile response.

A lip sealing tape for preventing a user's mouth from opening in daily life and during sleep is proposed. The lip sealing tape adds a mouth-closing vector to assist a vector that displaces a position of a user's tongue forward and upward, thereby forming a closed vector system of muscles of the entire body to increase physical stability and induce nasal respiration (breathing through a user's nose) to gradually reduce oral respiration while promoting nasal respiration. The lip sealing tape is characterized by simply adding the mouth-closing vector to prevent opening of the user's upper and lower lips, by means of horizontal and vertical adhesive tape portions, thereby minimizing a contact area with a user's facial skin when worn and thus minimizing discomfort due to stuffiness while maximizing safety when worn.

The invention relates to a film comprising an optionally multilayer carrier layer; wherein one surface side of the carrier layer has been modified over part of its area either by surface activation or by printing with a print medium, such that the surface side has modified regions and unmodified regions; wherein the modified regions and the unmodified regions are coated over part or all of the area by a release material; and wherein the strength of adhesion of the release material to the carrier layer in the modified regions is different compared to the adhesion of the release material to the carrier layer in the unmodified regions.

To provide a half-cut double-sided tape from a double-sided tape with a release-liner commercially available in the market by means of a simple process without contacting a cutter blade directly to an adhesive layer when making the half cuts in the half-cut process. The invention includes: a processing protection layer formation step of feeding a protect release paper tape having the release surface to the double-sided tape to form a processing protection layer on the double-sided tape with the release liner; a half-cut step of continuously performing half-cut together with the processing protection layer and the double-sided tape on the release liner while leaving only the release liner, and making a number of the double-sided tape pieces of proper length are held on the release liner; a half-cut double-sided tape winding step of winding the half-cut double-sided tape with the release liner while peeling off the processing protection layer. A cut trace has a fully cut region in the width direction of the double-sided tape on the release liner and a non-cut region in the width direction of the protect release paper tape, so that the peeling is facilitated.

This invention discloses an adhesive tape, for fluid-tight sealing, and for firm grip, said adhesive tape being a four-sided adhesive tape comprising: a first strip (1) having an operative ventral adhesive surface (11, 12) and an operative dorsal non-adhesive surface (31a, 31b), and a second strip (2) comprising an operative ventral non-adhesive surface (32a, 32b) and an operative dorsal adhesive surface (21, 22); a joint (4) between said first strip (1) and said second strip (2), an operative left side (11), of the first strip (1), and an operative right side (12), of the first strip (1), configured to bend at the joint (4); an operative left side (21), of the second strip (2), and an operative right side (22), of the second strip (2), configured to bend at the joint (4).

The present invention addresses the problem of providing a sound insulating structure which provides a sufficient sound insulating effect even when an adhesive layer is arranged therein, and in which a shift in the frequency band where the sound insulating effect is generated is unlikely to occur. This sound insulating structure includes, at least: a sound insulating member that includes a sheet-like sheet section and plural projections arranged on the sheet section; and an adhesive layer arranged on a surface of the sheet section on the opposite side of the side provided with the projections, and the sound insulating structure satisfies the following Formula (1): E_glue/I_glue>0.5×(E_membrane/H)(1) (wherein, E_glue (MPa): storage modulus of adhesive layer, I_glue (mm): average thickness of adhesive layer, E_membrane (MPa): storage modulus of sheet section and projections, and H (mm): average height of sheet section and projections).

An optical clear adhesive film is provided. A first tearing part is disposed on a first side of a first protective film, such that when an external force is applied to the first tearing part, a starting position at which the colloid layer is separated from the first protective film is a line contact. Therefore, the colloidal layer is less stressed at each point of separation, and phenomenon that the colloid layer is pulled is avoided.

An adhesive material that provides fast and robust adhesion on wet surfaces, where the adhesion formed is detachable on-demand. The adhesive material is formed of one or more hydrophilic polymers or copolymers grafted with one or more amine coupling groups via a plurality of cleavable physical bonds and/or cleavable covalent bonds and one or more cross linkers. Application of the adhesive material on a wet surface causes the adhesive material to absorb liquid to thereby swell the adhesive material to form a layer of hydrogel, resulting in the formation of temporary crosslinks followed by covalent crosslinks with the surface. Introducing a triggering agent cleaves the cleavable physical bonds and/or cleavable covalent bonds to allow for non-traumatic detachment of the adhesive material from the surface.
