  • Patent number: 6688649
    Abstract: A form with a well has a form layer with a top and a bottom surface and a perimeter, a die cut through the form layer that defines a portion of said form layer within said die cut, a patch layer having a perimeter and top and bottom surfaces, and an adhesive layer that is repositionable and peelable. The patch layer is adhesively but removably secured to the bottom surface of the form layer such that the die cut and form layer portion are entirely within the perimeter of the patch layer. The form has a well, that is created by removal of the form layer portion from within the die cut. The bottom of the well is the top surface of said adhesive layer and the sides of the well are the edges of said die cut. The adhesive layer has a greater affinity for the patch layer than the form layer portion such that when the form layer portion is removed from the form, the adhesive stays adhered to the patch layer. Articles such as photographs may then be inserted into the well.

    Abstract: A bookbinding structure and method. The bookbinding structure is used to bind pages together in existing, commercially available binding machines. The bookbinding structure has a heat activated adhesive matrix for binding the pages. To attach a wrap-around book cover once the pages have been bound with the bookbinding structure, an adhesive on the outer surface of the bookbinding structure may be exposed by removing a release liner covering the adhesive. The book cover may then be adhered to the exposed adhesive either by a heat method or by applying pressure over the adhesive, depending on the particular type of adhesive of the bookbinding structure. The book cover may be printed with information and/or graphics prior to being wrapped around the pages of the book.

  • Patent number: 6596360
    Abstract: In the multilayer volume hologram 1 of the invention, the adhesive layer 5, volume hologram 6 and surface protective film 7 are laminated on the application member 2 in this order, and the breaking strength of the hologram layer should be larger than the peel strength between the surface protective film and the volume hologram layer and smaller than the peel strength with which the hologram layer is peeled off the application member and the breaking strength of the surface protective film. This multilayer volume hologram provides a more improved protection for the volume hologram. A portrait replacement or falsification of an information area ensures that the volume hologram layer can break down. Thus, more reliable counterfeit-proofness is achievable.

    Abstract: Label sheets are formed from a continuous web of laminated stock material comprising a face stock layer and a liner layer secured together by an adhesive layer. The stock material is delaminated and an adhesive deactivating material is applied to the adhesive layer in longitudinal strips to create active and inactive adhesive portions. Label sheets are formed by cutting the web of stock material transversely. Individual labels are formed on the label sheets by kiss-cutting the face stock layer. Each individual label includes an attachment end with active adhesive and a free/unattached end with inactive adhesive. A method of manufacturing partially-secured labels includes the steps of delaminating a stock material, deactivating strips of an adhesive layer, and relaminating the stock material.

A method of manufacturing image transfer sheets includes first applying a water impermeable layer onto a flexible substrate. A layer of water-activatable adhesive is applied upon the water impermeable layer. The adhesive is then dried in a dryer with dehumidified air. A water permeable detack layer is then applied upon the layer of adhesive. In a particular embodiment, the sheet further includes a water-accepting image holding layer in between the water-accepting adhesive layer and the water impermeable layer. The image holding layer becomes water-resisting when heated to within a range of activation temperatures.

    Abstract: There are provided a hologram laminate and a hologram label which do not involve any problem in the production process per se of forging preventive labels using a volume hologram, can provide a reliable process of the attainment of forgery preventive effect, and can make difficult to notice the signs of the forgery preventive processing. In applying a protective film 108 onto a hologram 107 through a second pressure-sensitive adhesive 109, the adhesive strength is partially varied. By virtue of this construction, upon separation of the protective film 108, the second pressure-sensitive adhesive 109 is partially left on the hologram 107, so that the fact of the separation can be found out. Likewise, the adhesive strength of a first pressure-sensitive adhesive 106 can be partially changed. Further, the adhesive strength of the first pressure-sensitive adhesive 106 is larger than 1% tensile strength of the hologram 107.

  • Patent number: 6482487
    Abstract: A unitary stack of paper sheets have individual paper sheets which are loosely bonded together in a manner whereby an individual paper sheet is easily removed and used as a base. Each paper sheet in the unitary stack has a pressure sensitive adhesive partially covering each face thereof in approximate aligned areas of the respective faces. A back face of the individual sheet is adhered to a substrate while a front face holds an item for posting. In use, an individual paper sheet is readily removed from the unitary stack, adhered on its back face to the substrate, and then an item posted on its front face.

  • Patent number: 6475314
    Abstract: An adhesive lamination has patches of an adhesive layer which correspond to predetermined positions on a plurality of circuit boards, and the adhesive layer is applied across the plurality of circuit boards. This adhesive lamination is composed of a first separation sheet, a second separation sheet and the adhesive layer interposed between the first and second separation sheets. A number of patches of the adhesive layer are formed on the first separation sheet and arranged so that the length of the patch of the adhesive layer is approximately parallel to the short side of the first separation sheet.

  • Patent number: 6458442
    Abstract: A cleaning mat according to the present invention is designed to be placed on a floor and to clean the undersides of shoes, feet, and other objects. The cleaning pad includes a base sheet, which is designed to rest on the floor. The base sheet has an upper surface and lower surface with the lower surface designed to contact the floor. Multiple removable and disposable cleaning sheets are supported in a stacked configuration on the upper surface of the base sheet. Each of the cleaning sheets includes an upper bibulous layer having an upper face. The bibulous layer is designed to absorb liquid from an object that contacts the upper face. Each cleaning sheet also includes a lower moisture barrier layer that has an upper face adjacent the bibulous layer. The barrier layer is operative to prevent transport of liquid from the bibulous layer to other cleaning sheets below the barrier layer.

  • Patent number: 6436499
    Abstract: The present invention is directed to a cold seal package that includes constructions wherein two substrates, or two portions of one substrate, are sealingly engaged to one another using a substantially natural latex rubber-free contact adhesive. The two substrates can be easily peeled apart without substantial damage to the substrates. Furthermore, the substrates cannot typically be resealed, or refastened, once peeled apart. That is, the cold seal formed by the adhesive between the substrates is substantially non-refastenable. Advantageously, a cold seal package of the present invention is particularly well suited for aseptic delivery of packaged goods, such as bandages, dressings, and the like.

  • Patent number: 6428867
    Abstract: A resealable label flap for use with a product package including a tamper indicating tab that remains in contact with the package body to indicate that the label flap has been removed from the package body. The tamper indicating tab includes a first ink layer that defines an indicia or pattern on the top surface of the tamper indicating tab. A second ink layer is applied over the entire top surface of the tamper indicating tab, including over the first ink layer. The second ink layer does not bond to the first ink layer. When the label flap is initially pulled from the product package, the tamper indicating tab separates from the remaining portions of the label flap. As the tamper indicating tab separates from the label flap, the first ink layer and the second ink layer separate from each other such that the portions of the second ink layer applied over the first ink layer remain in contact with the top layer of the label flap.
