摘要:
Deactivating a data tag attached to packaging for user privacy or tamper-evident reasons. Each of a plurality of data tags stores identification information. At least one of the data tags is removable and capable of wireless signal transmission at a first range such that removal of the data tag substantially prevents communication of the identification information via the removed data tag and permits communication of the identification information via another data tag at a second range relatively smaller than the first range.

摘要:
Mechanically and reversibly activating or deactivating a radio frequency identification (RFID) data tag. An RFID tag includes an RFID chip for storing an RFID code, an antenna for communicating a radio frequency (RF) signal, and a mechanical switch coupling the RFID chip to the antenna. Closing the mechanical switch enables the RFID chip and the antenna to communicate the RFID code via the RF signal.

摘要:
An absorbent article is disclosed comprising a thin, flexible wicking barrier with a horizontal portion that is folded back upon itself to create a substantially longitudinal cuff. The wicking barrier can separate a central absorbent member from an outer absorbent member for improved center fill, with the cuff open toward the central absorbent member to intercept liquid flowing toward the longitudinal sides of the article. The wicking barrier cuff desirably contains spacer means to hold the cuff open, providing void space to receive fluid. In one embodiment, lateral compression of the article during use causes the wicking barrier cuff to lift up from the surface of the article, creating a bubble of topsheet material and wicking barrier material (a “dynamic bubble cuff”) that intercepts fluid and improves body fit and leakage prevention.

Paper sheets useful for tissues, paper towels, napkins, disposable absorbent products and the like can be made to exhibit a high degree of wet resiliency. This property is achieved by using a combination of high yield pulp fibers (such as bleached chemithermomechanical pulp fibers) and a wet strength agent in an uncreped throughdrying process. The resulting product, when wetted, can spring back after being crumpled in one's hand.
摘要:
Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form. The use of large diameter rolls with soft rubber covers can also be used.
摘要:
A web for use in applying a functional material is provided. The web includes a layer that has a plurality of elevated regions. The layer defines a plurality of cavities such that the cavities are located between adjacent elevated regions. A plurality of depressed regions are located on the layer intermediate the elevated regions. The layer has a longitudinal direction and a longitudinal mid-plane defined therethrough. A plurality of functional material members are located in the cavities of the layer. The functional material members are adapted for adhesion of particles or surfaces thereon. The layer is extendable in the longitudinal direction so that the elevated regions are moved in a direction towards the longitudinal mid-plane.
