Conformable pressure-sensitive adhesive tapes which comprise a layer of polymeric foam in the backing and may be adhered firmly to a substrate and thereafter removed therefrom after only being stretched at an angle no greater than about 35&#xb0; from the surface of the substrate. Articles for mounting an object such as a picture to a surface such as a wall comprising a pressure-sensitive adhesive tape of the invention are also described.

Removable foam adhesive tape

A hanger comprising a base having a supported surface adapted to be positioned along a generally vertical surface, and an elongate peg having one end mounted on the base with a portion of the peg projecting from an outer surface of the base opposite its supported surface generally at a right angle with respect to the supported surface of the base. The peg has an axially extending surface portion adapted to be positioned uppermost when the supported surface of the base is positioned along a generally vertical surface, which axially extending surface portion restricts free movement axially of the peg of sheets of paper around and hanging on the peg. That axially extending surface portion can be defined by a layer of adhesive on the peg or by closely spaced sharp edges on the peg. Such sharp edges could be on screw threads around the peg, ridges extending transversely across the peg, serrations formed on the peg, or by abrasive granules adhered along the peg.

An adhesively mounted single-sided clamp-like device for producing a compressive force or tensile force includes a body, a plunger movably connected with the body, and a double-sided stretch releasing adhesive attached to at least one of the body and the plunger. The body and/or plunger can be firmly adhesively bonded to a surface or object and later cleanly removed from the surface or plunger without damaging the surface and without leaving adhesive residue by stretching the adhesive.

Adhesively mounted clamp device

A method of applying a tensile or compressive force to a selected location of a work piece or surface without damaging the work piece or the surface and without leaving adhesive residue thereon includes providing a device including a body member and a force applying member movably connected with the body member, attaching the body member and/or the force applying member to the work piece and/or surface using a double-sided stretch releasing adhesive such that one end of the force applying member is adjacent the selected location, and moving the force applying member toward the work piece or surface to generate a compressive force, or moving the force applying member away from the work piece or surface to generate a tensile force.

An adhesive tape construction is removable from one or more objects to which it is adhered and which is reusably separable within its construction so that an object can be separated from another and subsequently reconnected with one another. The adhesive tape construction can be used to bond the other opposed surfaces of objects, including rigid objects such as a picture frame to a wall, where no portion of the adhesive tape construction projects from between the objects, and which subsequently affords easy separation of the objects without damage to either of them. More specifically, the adhesive tape construction includes a stretch release adhesive tape structure combined with a reusable connector surface.

Removable adhesive tape laminate and separable fastener

An adhesive article adapted to attach structures to a substrate and a method of using the same. The adhesive article has a failure mode that minimizes damage to the substrate surface. The adhesive article comprises an adhesive layer having a first adhesive region and a second adhesive region. The first adhesive region is adapted to attach a top portion of the structure to the substrate. The second adhesive region is adapted to attach a bottom portion of the structure to the substrate. The second adhesive region comprises reduced adhesive properties.

Adhesive article with progressive adhesive properties and method of using same

A stretch releasing adhesive tape article including an elongated length of stretch releasing adhesive tape with side surfaces including at least one potential contact surface area. At least a portion of the potential contact surface area includes an adhesive surface. The potential contact surface area includes a first interface surface area in the uncompressed state and a second interface surface area greater than the first interface surface area in the compressed state. The stretch releasing adhesive tape in the uncompressed state can operate as a pull tab. The potential contact surface area in the uncompressed state can include a plurality of raised portions, a non-planar structure, or a discontinuous surface.

Stretch releasing adhesive tape with differential adhesive properties

An article for use with a stretch releasing adhesive tape strip having a non-adhesive pull tab includes a unitary attachment member having a base plate portion sized to overlay the entire stretch releasing adhesive tape strip. The base plate portion includes a first portion that overlays the adhesive portion of tape strip and a flexible cover portion that overlays the non-adhesive pull tab. A user can manually urge the cover portion away from the pull tab, thereby accessing the pull tab and allowing the user to stretch remove the tape strip from the unitary attachment member and a substrate to which it is adhered.

Stretch releasing adhesive tape article with flexible cover

A package assembly including a housing that has an attachable portion and a manually removable portion. Also included is a length of attachment strip material having opposite major surfaces defined by stretch release adhesive extending between its opposite ends. The length of attachment strip material has a first part adhered along the outer surface of the attachable portion of the housing, and a second part extending from one end of the first part; and that second part of the length of attachment strip material is disposed to restrict adhesion between it and a planar surface to which the first part of the length of attachment strip material is adhered to support the housing along that surface. The manually removable portion of the housing is manually removable from the attachable portion of the housing to afford stretching of the first part of the length of attachment strip material by pulling its second part away from its first part, thereby removing the first part of the attachment strip material from between the attachable portion of the housing and that surface.

Package assemblies with attachment strips

A tape laminate adapted to support or locate an object along a substrate. The tape laminate comprises a support layer of strong, flexible, conformable, essentially non stretchable material having firmly attached thereto an attachment strip comprising a layer of stretch release adhesive defining an exposed major surface that is adapted to adhere the attachment strip to the substrate. In one embodiment, consisting only of the conformable support layer and the attachment strip, the tape laminate can be used to support or locate an object along a substrate (e.g., along a vertical wall) by conforming the tape laminate to the contour of portions of the object and of the wall and adhering a part of the layer of stretch release adhesive to each of those portions. In other embodiments, the tape laminate further includes means such as separable fasteners, twist ties, cable ties, elastic bands, or hooks for facilitating engagement of objects to be supported or located by the tape laminate.

Removable tape laminate including a flexible non-stretchable support layer

An elongated length of a single or double-sided stretch releasing adhesive tape that can be cut to a selected length with integral pull tabs for stretch removing the tape from a substrate. The stretch releasing adhesive tape can be provided as long strips or roll form. The elongated stretch releasing adhesive tape article includes an elongate length of stretch releasing adhesive tape defining a longitudinal axis. The stretch releasing adhesive tape has a first surface and a second non-adhesive surface. The first surface comprises one or more adhesive regions and one or more non-adhesive regions arranged along the longitudinal axis. At least a portion of the non-adhesive regions comprise a series of pull tabs arranged along the longitudinal axis that can be grasped in combination with the second non-adhesive surface by a user during stretch removal of the tape from an associated substrate.

Stretch releasing adhesive tape with integral pull tab

An article support adapted for adhering to a substrate is described. The article support preferably includes a base member, a stretch release adhesive tape adhered to that base member, and some mechanism for gripping the stretch release adhesive tape. These items are arranged so that when the base member is adhered to the substrate by the stretch release adhesive tape, the base member can be removed by pulling on the gripping means at an acute angle from the surface of the substrate. Gripping means which resist disassociation from the stretch release adhesive tape during the removal of the base from the substrate are disclosed, including handle types. The base member can be generic, suitable for attaching various types of support members via, for example, complimentary dovetail slides. In such cases, provision such as a latch can be made to temporarily lock the support member to the base member. The article support can be provided so that when the support member is removed from the base member, the gripping mechanism engages the support member to automatically stretch the tape and remove the base member from the substrate.
