摘要:
The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) are used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive. The adhesive compositions of the present invention are suitable for use in the preparation of laminated disposable absorbent products.

摘要:
An apparatus for conveying information and a method of using said apparatus during a medical emergency. The apparatus consists of a perforated adhesive tape with a front side and a back side. The back side includes an adhesive applied thereto to enable the tape to be affixed to a secondary surface. The front side includes borders on each side thereof. The borders are comprised of a reflective material. A middle section between the two borders includes a material with a surface adapted to receive indicia from a writing utensil. Adjacent segments of the tape are separated by perforations. During use, a writing utensil may be used to apply indicia to the middle section of a segment of the tape. The segment may be removed from an adjacent segment along the perforations, and the tape may be applied to a secondary surface.

摘要:
The present invention involves an applique for applying a fabric pattern to an object. The applique comprises a laminate having an outer periphery to define a first predetermined shape corresponding to the fabric pattern and has etches formed adjacent the periphery to simulate an appearance of stitching. In one embodiment, the laminate comprises a top fabric layer and a bottom fabric layer with a periphery, wherein the bottom fabric layer periphery corresponds to the outer periphery. The top fabric layer is a strip attached to the bottom layer, wherein the top fabric layer is disposed adjacent the outer periphery. The laminate has etches formed on the top fabric layer so that the top fabric layer simulates the appearance of stitching. In another embodiment, the laminate comprises a top fabric layer and a bottom fabric layer, wherein the top fabric layer has a second predetermined shape. The top fabric layer is attached to the bottom fabric layer and disposed inward from the outer periphery. The bottom fabric layer has the first predetermined shape and etches formed thereon adjacent the outer periphery.
摘要:
A cover tape for winding on a grip of a device comprising an elongated cloth layer and an elastic layer. The cloth layer has a first surface and a second surface. The elastic layer is made of silicone gel and bonded to the first surface of the cloth layer for enabling the second surface of the cloth layer to be exposed to the outside when spirally winding the cover tape round the grip with the elastic layer adhered to the periphery of the grip.
