Abstract: A toothbrush has a head extending from a neck which extends from a handle, and the head has a plurality of tooth cleaning elements extending therefrom. A first group of tooth cleaning elements is located towards a free end of the head, and a second group of tooth cleaning elements is located towards the outside of the head. A third group of tooth cleaning elements, which alternate with the second group of tufts, are oriented at an acute angle to a top surface of the head in a direction that is across the width of the head. A fourth group of tooth cleaning elements is located toward the inside of the head, and each is made of a thermoplastic elastomer and each is in the shape of a curved wall. A fifth group of tooth cleaning elements is located towards the inside of the head.

Abstract: A method and apparatus for assessing the abrasiveness of a brush is provided. The method includes providing a destructible article, providing a brush, such as for example a toothbrush, brushing the destructible article with the toothbrush, examining the destructible article after brushing with the toothbrush and determining the abrasive quality of the toothbrush as a function of the appearance of the destructible article. The apparatus for determining the abrasiveness of a toothbrush includes a holder for retaining a toothbrush having a head and a neck, a support for holding a destructible article, a mechanism for moving the head of the toothbrush against the destructible article in a brushing fashion, and a biasing member for applying a selected brushing force between the head of the toothbrush and the destructible article.
Abstract: A packaged absorbent article having a body surface and a garment surface; and a wrapper sheet for wrapping the absorbent article so that at least a portion of the garment surface of the absorbent article can be seen through the wrapper sheet.
Abstract: The invention relates to absorbent structures for use in absorbent articles. The structures include a first region for distribution of fluid and a second region for storage of fluid. The first region contains materials, with a relatively high capillary desorption pressure, while the second region contains materials exhibiting a sufficiently high capillary absorption pressure efficiently drain the first region. Exemplary materials have a CSDH 50 of more than 40 cm, and a second region containing a material which satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm (b) an absorption capacity of at least 15 g/g at 0 cm and an absorption efficiency of at least 55% at 40 cm; and (c) a Capillary Sorption Absorption height at 50% of its capacity at 0 cm absorption height (CSAH 50) of at least 35 cm.
Abstract: A device for printing a web moving in a direction (YB), wherein ink jets print on the web a printing width across its direction (YB) of advancement while traversing a printing station. The printing station includes one or more printer heads that produce ink jets over a footprint width which is narrower than the intended printing width over the web. One or more shaping elements bestow on the web traversing the printing station a V-shape so that the web is at least locally oriented oblique to the linear array of nozzles that project the ink. The ink from the printer head(s) is thus printed over the intended printing width of the web.
