摘要:
A bonding structure of check-valves to a fluid container and a production apparatus of fluid container which is capable of reliably keeping the expansion of the fluid container without any fluid leakage after inflating the fluid container. As the check-valve is bonded to only one of thermoplastic container films, both films of the check-valve is fixed to one of the container films, thereby preventing the reverse flow by tightly closing the check valve. As a result, the expansion of the fluid container is reliably maintained after the fluid container is inflated. The manufacturing apparatus includes an up-down roller controller which precisely positions the film to form the check valve. As a result, the manufacturing apparatus can produce the fluid container having the reliable check valves.

A compound curved shaped housing part (104) includes integrated activatable electrochromic indicia (114, 116, 118, 120). The indicia are formed by coating an internal surface (302) of a transparent plastic shell (402) with a sequence of layers including: optionally a separate transparent conductor (408), an electrochromic material layer (410), an electrolyte layer (412), optionally a separate ion donor layer (414), optionally an insulator layer 418 and a second conductive layer. Laser etching is used to provide access to the transparent conductor layer. The insulator layer is patterned to provide access for electrodes to underlying layers. Laser etching is used to pattern the second conductive layer to define interconnected electrodes (322-332), traces (314-318), and electrical contacts (304-312).

A method of making a texture-coated and/or insulation coated container from a flat paperboard blank in which a heat-hardenable liquid polymeric binder texturizing and/or insulating agent coating mixture is applied to one surface of the blank in a pattern of covered and open areas. This coating mixture is subjected to heat to cure the polymeric binder and expand the texturizing and/or insulating agent, optionally treated with moisture, and optionally heated to form the blank into the shape of a container, and the container produced by this method. The containers such as cups, plates, etc., are useful in food service. These containers have a coefficient of static friction which is about 0.2 to 2.0 and over and a kinetic coefficient of friction which is about 0.22 to 1.5.

A cling film system includes first and second film piles having different composition. Each film ply includes at least one cling layer and, desirably, one or more additional layers. Each film ply includes an overlapping portion and a second portion. The cling layer of the first film ply engages the cling layer of the second film ply in the overlapping portion of the first film ply and in the overlapping portion of the second film ply.

A waste block includes an outer housing made of soil material and having a chamber, and a waste insert engaged into the chamber of the outer housing and secured in the outer housing with compressing processes, for allowing the waste insert to be solidly and safely retained within the outer housing, and for preventing the waste insert from polluting the outer environment. The waste block may include one or more recesses or notches or juts or bulges for engaging with each other and for stably superposing a number of waste blocks together.

An image structure formed on a medium. The image structure is so formed that an angular distribution of surface reflection light beams under the condition that a surface of an image G formed on a medium is irradiated with a slit-transmitted light beam satisfies the following three characteristics: (1) an angle A corresponding to a half value of a reflected light peak is not smaller than unity but not larger than twice as large as a reference angle A0; (2) the ratio nullXGWS/nullXGWS0 of the value of WS of center-of-gravity fluctuation to the value of reference WS0 of center-of-gravity fluctuation is not larger than 10; and (3) an angle B at which the quantity of reflected light becomes {fraction (1/10)} as large as the peak value is in a range of from 3nullA0 to 6nullA0, both inclusively.
摘要:
A container closure with a multiple layer liner. The liner comprises a nylon gas transmission barrier and a non-nylon layer bonded by an adhesive layer. The nylon gas transmission barrier may contain an additional passive gas transmission component comprising an in-situ polymerized inorganic clay. An additional active gas transmission component comprising a chemically reactive scavenger may be incorporated into at least one layer of the multiple layer liner. Materials of the liner are selected for their process conditions and resulting resistance to degradation.
摘要:
Thin-walled rubber articles for use contact with living tissue or with materials to be delivered to living tissue are prepared from aqueous latex of either natural rubber or synthetic cis-1,4-polyisoprene by vulcanization to produce both carbon-carbon and carbon-(sulfur)n-carbon crosslinks, the vulcanization being performed in the absence of any compounding components that contain secondary amine groups or any components that have a tendency to produce nitrosamines. While sulfur activators may be included, it is preferable that no sulfur accelerators at all be included. Thin-walled rubber articles formed from the latex surprisingly exhibit a combination of high tensile strength, high ultimate percent elongation, and low 500% tensile modulus. The process is particularly effective in the manufacture of thin-walled articles from synthetic cis-1,4-polyisoprene.

A biocide containing laminate for use in the construction of a wide variety of products. A preferred product is a pouch or other container for forming an envelope protectively packaging a product such as a flowable or solid food substance. The pouch is fabricated from a paper-plastic laminate sheeting whose plies have different properties that depend on package requirements, at least one ply in the laminate being an oriented, synthetic plastic film of high tensile strength. The plies are adhesively laminated at ambient temperature with a water-based adhesive whereby the orientation of the film is unaffected by the laminating process, in the course of which no environmentally objectionable fumes are discharged into the atmosphere. The biocide is associated with the paper material or water-based adhesive of the laminate in an amount sufficient to render it resistant to attack from organisms. The plastic film protects and retains the biocide in the laminate. The laminate may be made into an organism-resistant tape, a water-resistant envelope, or a package for mailing various materials.

The present invention involves a failure resistant receptacle of a puncture-resistant rollstock or bag including an inner bag formed from a seamless tube of material e.g. a lay-flat tube member having a first tube wall and an opposed second tube wall and having a first tube edge, an opposed second tube edge, a first tube end and an opposed second tube end where the first and second tube walls define a product receiving chamber and further having first and second outer film members affixed to opposing outer surfaces respectively of the first and second tube walls and extending continuously between the first and second tube ends. Optionally, the first and/or second outer film members may be narrower, coextensive, or extend beyond one or both of the first and second tube edges of the lay-flat tube member. In a bag embodiment a lateral seal is provided through the first and second tube walls and the first and second outer film members and extends laterally across the width of at least the lay-flat tube member. Methods of manufacturing such rollstock and bags are also disclosed.
