Abstract: A one-way valve is mounted over a vent hole in a flexible package to enable gases to vent. The valve has a flexible base layer, a flexible cover layer and an interposed layer of oil. Each layer has an opposed pair of side edges. The cover layer is thinner than the base layer and is secured to the base layer along respective contiguous portions of the side edges to form an openable channel. The oil layer is located in the channel between the base layer and the cover layer and over the hole to form a bond holding the cover layer on the base layer until pressure within the package causes the bond to break, whereupon the cover layer to lift ups and opens the hole valve. Methods of making the package and valve are also disclosed.

Abstract: To provide a check valve and a sealing bag that are high in certainty of the checking effect and prevented as much as possible from increasing in the production cost.

Abstract: A portable and sealable waste disposal receptacle receives human waste material through an opening in an outer chamber. The waste passes through an inner chamber, which is suspended within the outer chamber, and passes through a one-way valve located at the bottom of the inner chamber into a lower chamber portion of the outer chamber. The one-way valve is fashioned from the bottom edges of the inner chamber, where a biasing strip is mounted in compression along one of the bottom edges, which causes the bottom edges of the inner chamber to be biased closed in sealing contact except when waste enters the inner chamber, the weight of which is sufficient to overcome the closing bias of the biasing strip, allowing the waste to flow into the lower chamber. Once the waste has cleared the inner chamber, the biasing member causes the bottom edges to come together in sealing contact, preventing the flow of waste back through the inner chamber.

Abstract: A retaining element for use with elastic sheet material is disclosed. In one form, the sheet material can be provided as a bag (100) having first and second side walls (102, 104). The retaining element can be in the form of an elastic strip attached to one of the side walls. The retaining strip (120) can comprise a heat-unstable activatable material such that it can be applied to the bag in a deadened condition wherein the strip is set and subsequently heated to transition to an activated condition wherein the retaining element is elasticized to provide an elasticized article which can have a shirred appearance. The retaining element can have various configurations and can be activated by various methods.

Abstract: A device for applying light conductive fibers onto substrates and having a mounting yoke, a holding device and a stamping device. The holding device is configured as a U-shaped base body with an upward arching outside area having guide grooves and holders for installing the fibers in the device. The stamping device consists of a stamp, a stamp neck and a stamp head, which are inserted and linearly guided in the U-shaped die sink in the holding device. The device ensures a precise positioning of fibers and in particular of functional units in fiber segments. Fiber breaks can be nearly ruled out with the application method. The separating foils ensure that the device can be removed after the adhesive has hardened, so that no force is exerted onto the fiber through excess adhesive that sticks.

Abstract: A containment and disposal bag for human bodily fluids is disclosed which includes a bag having a hollow interior and a top at least partially open to receive the bodily fluids; preferably a funnel structure within the bag to channel said bodily fluids into the interior and to restrict expulsion of bodily fluids from the interior prior to sequestration; a hydrophilic material within the bag which is rapidly gellable upon contact with the bodily fluids in the bag, the gellation serving to essentially completely sequester the bodily fluids and prevent it from thereafter being expelled from the bag; and a closure to close the top of the bag after introduction of the bodily fluids into the bag. The hydrophilic material is commonly a polymer which is activated upon contact with the water-based bodily fluids and which gels rapidly (normally within thirty seconds or less) to sequester the bodily fluids.

Abstract: A coin holding device comprises a pair of generally rectangular resilient wall members, at least one of which is preferably transparent. The two flexible walls are secured to one another along three perimeter edges. The remaining perimeter edge is unsecured. An inner flexible transparent pouch for holding coins and the like is contained within the wall members. The front end of the pouch has gently curved front walls leading to an opening through which coins may be inserted and removed. A pair of resilient flaps extends inwardly from the unsecured edges of the flexible walls. The flaps are joined along a central seam. A small relieved region in each flap forms an aperture in the central seam. The opening of the flexible pouch is joined to the flaps at the aperture. Absent pressure from a user, the resilient wall members remain flat and hold the coin aperture closed.

Abstract: A bag is provided which is inclusive of a mouth for the insertion of objects to be stored in the bag. The bag is provided with an input section at the mouth to guide the objects via the mouth into the bag. The input section is adapted for being curled in order to function as a closure for the mouth. A retainer is furthermore provided for being hooded over the input section with the latter having been curled thereby to retain the closure at the mouth. A substantially rigid bar of curved form is provided on the bag at the mouth for imparting a curved conformation to the structure to enhance the closure. The retainer is preferably of a pouch-like configuration defining a receptacle to receive the input section in its curled condition. The bag and input section are of a monolithic construction which is of a waterproof material.
