The valve 30 controls admission of air to a bladder 10 from a pump 8. The valve comprises strips 32 and 34 which are sealed together along their longitudinal edges to define a central passage 38. The strips 32 and 34 are preferably of the same material as the sheets 16 and 18 forming the bladder but of smaller thickness. The strips 32 and 34 are separated at the inlet end by a release coating 40 which prevents them being sealed together when the valve is sealed between the sheets 16 and 18 at 21. The inner surfaces of the strips are smooth to cause them to adhere together until pressure is applied by the pump. The outer surfaces are matt to prevent sticking to the sheets 16 and 18. The seal 21 is preferably of V shape with the apex pointing towards the pump to facilitate separation of the strips 32 and 34 when the valve is first used.

A waterproof insert for lining the interior of contoured articles of clothing is described, which comprises two superimposed layers, each of which is a laminate composed of a sheet of porous polymeric membrane (1, 1') and a sheet of textile material (3, 3'), the said sheet of polymeric membrane being breathable but waterproof and coated with a breathable, hydrophilic polymer. The sheets are laminated by means of a discontinuous adhesive (2, 2') and the layers are joined to form a uniformly welded seam. The inserts slide easily over the inner protective lining of the article of clothing.

On a mis au point un gant comprenant une feuille frontale (9) et une feuille arrière (10). Au moins une des feuilles se compose d'une couche extérieure (12) et d'une couche intérieure (13) faite de films polymères. Lesdites couches sont liées l'une à l'autre. Les faces (18) se faisant face d'au moins deux couches adjacentes (12, 13) sont indépendantes l'une de l'autre de manière à permettre un mouvement relatif (M) entre les deux couches (12, 13).
摘要:
A flexible dipped rubber article having a lubricating layer formed from a hydrogel polymer bonded thereto so as to provide a skin-contacting surface of said article, characterised in that the lubricating layer is formed by applying a solution of a hydrophilic hydrogel-forming polymer to the dipped rubber article prior to complete vulcanisation thereof, and curing the polymer and vulcanising the rubber.

A disposable glove (20) for medical use and the like includes a closed distal end (22) for containing the wearer's fingers, an open proximal end (31), and a cuff portion (32) at the open proximal end (31). Adhesive (35) is provided on a portion of the cuff for allowing the portion of the cuff to be removably secured to other portions of the cuff for tightening the cuff (32) when the glove (20) is on the wearer's hand. A method of making the glove (20) is also disclosed.

Un gant ou une moufle en caoutchouc ou un plastique comprend un élément de nettoyage fixé au moins à la partie avant du gant ou de la moufle au niveau de la région des doigts. Un procédé de fabrication dudit gant ou de ladite moufle consiste à: (a) plonger un calibre de forme dans une cuve de caoutchouc de latex jusqu'à ce que l'épaisseur de caoutchouc requise adhère au calibre de forme; (b) soumettre le caoutchouc adhéré à un lessivage en plongeant le calibre de forme auquel est adhéré le caoutchouc dans une cuve d'une solution halogène aqueuse; (c) retirer, retourner et replacer le gant ou la moufle sur le calibre de forme; (d) répéter l'opération (b); (e) retirer le gant ou la moufle du calibre de forme et le/la placer sur une surface plate; et (f) fixer soit un élément de nettoyage soit un second élément d'attache à au moins la partie avant du gant ou de la moufle au niveau de la région des doigts.

Des gants et d'autres articles sont fabriqués à partir d'une paire de feuilles thermoplastiques (12, 14) adjacentes et disposées l'une en face de l'autre et défilant le long d'une chaîne de traitement. Une partie de l'une des feuilles est poussée (12) vers l'extérieur pour former une boucle (58) en saillie vers l'extérieur, et une ligne en forme de pouce (24) est formée entre les côtés adjacents de la boucle. On fait ensuite avancer la boucle et les parties adjacentes des feuilles thermoplastiques jusqu'à un poste de façonnage des doigts et de la main (80), où des lignes thermosoudées (26, 28) correspondant à la forme des doigts et de la main sont formées entre les feuilles thermoplastiques en alignement avec la ligne en forme de pouces, tout en maintenant une partie de poignet ouverte. Il est ainsi possible de découper dans la partie de poignet le gant ainsi produit.
摘要:
Disposable glove of synthetic material, more especially softened polyvinyl chloride, which is treated with a powdery material which can be bonded with the glove surface and thereby forms minute nodules in this. In accordance with the procedure this is done by preheated forms of china or metal being dipped in plastisol and thereafter pregelatinized. The forms with the prege!atinized glove coating are thereafter treated in a fluidized bed or are sprayed with a powdery material having a particle size of between 50-500 microns. The coated forms are then heated until the coating gelantinizes and the applied material adheres to it. When, after cooling, the glove coating is rolled off the forms, the inside of the glove will have a great number of minute nodules, which will prevent it from sticking to itself, and which also makes the glove easier to pull on and off, since the minute nodules allow air to enter between the glove and the hand.
摘要:
A rubber article (such as a surgeon's glove) is provided with a skin contacting lubricating layer formed from a hydrogel polymer which is a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) and/or with 2-ethylhexyl acrylate (EHA) or other alkyl acrylate or alkyl methacrylate. Such hydrogel polymers have improved lubricity to dry skin.

Disclosed are a work glove, which prevents slip and improves wearability by using waterborne polyurethane dispersion foam and halite, and a method of fabricating the same. The method includes (a) preparing pre-treatment solution consisting of methanol and a calcium nitrate or the methanol and an acid-based material, (b) depositing the glove into the prepared pre-treatment solution and drying the glove, (c) coating a waterborne polyurethane dispersion foam on a portion of a surface of the dried glove by dipping the portion of the surface of the glove into the waterborne polyurethane dispersion foam, and (d) applying a surface-treatment powder to the coated portion of the glove and drying the coated portion of the glove.
