A trash container having a base and sides, at least a portion of the sides being formed of resilient horizontal pleated material throughout the circumference thereof, and a plunger fitting within the trash container and having a horizontal cross-section conforming to the internal horizontal cross-section of the trash container, the plunger including lips extending about the periphery thereof and shaped and dimensioned to fit over the upper edges of the sides. Alternatively, the top of the container may be used as a plunger. Pressure on the plunger will cause the sides to compress the pleated material, permitting the plunger to be pressed downwardly on the trash and compacting it. In a modification, the sides are rigid and the resilient pleated material is in the top of the container. The pleated or other resilient material has a memory and, so, will return to its original shape after pressure is removed.

The invention is providing a flexibility stiff reinforcing member that will maintain the shape of a pad for absorption of human exudate, such as a feminine hygiene pad, during use. The flexibly stiff reinforcing member will return the pad to its desired shape, even after it has been deformed by movement of the wearer. In a particularly preferred form, the flexibly stiff reinforcing member is a flat strip of polyethylene that extends around the periphery of a feminine hygiene pad. In other embodiments, the resilient reinforcing member may only be present in the periphery of the center or crotch portion of the pad. The strength and flexibility required of the reinforcing member will vary depending on the pad stiffness prior to reinforcing of the pad and the use to which the pad is to be put. The reinforcing element is a flexibly stiff, resilient, substantially nonelastic material. The reinforcing element material may be deformed and then is springy and will return to its shape after deformation.

A dispenser is provided for vaporizable materials such as deodorants and insecticides. The dispenser is adapted to create accentuated air flow over the materials either in the presence of ambient air flow or when the dispenser is moved through the air, for example, by being mounted on the back of a door. It dispenses far smaller quantities in the absence of air movement.The dispenser includes one or more material containers open at one end and mounted within a vented housing. The vents on the housing are positioned over a portion of the open end of the contained material, and are recessed in a concave area of the housing. The housing is spaced from the material container and has exit ports along its periphery. The containers preferably have a dividing partition passing part way down the material container to provide paths for the air to flow down one side and up on the other for better contact with the vaporizable material. The result is that relative motion between the dispenser and the ambient air creates one-way air flow pattern into the central ports, across the vaporizable material, and out the back of the unit.The unit is mounted in a place where it will periodically be moved, such as on a door, or where it would be subject to periodic air flows, such as on the wall adjacent a door.

A reinforcing member is disclosed that will maintain the shape of a product for absorption of human exudate, such as a feminine hygiene pad, diaper or incontinent garment during use. The flexibly stiff reinforcing member will return the pad to its desired shape, even after it has been deformed by movement of the wearer. In one form, the reinforcing member is a flat strip of polyethylene that extends around the periphery of the product. In other embodiments, the resilient reinforcing member may be present only in the periphery of the center or crotch portion of the product. The strength and flexibility required of the reinforcing member will vary depending upon the product stiffness prior to being reinforced and the use for which the product is designed. The reinforcing element is a flexibly stiff, resilient, substantially nonelastic material.
摘要:
A linear sheath valve having a valve platform and a conforming cover. The valve platform can have inlet and outlet channels to carry liquid into and out of the valve. An elastomeric membrane is held under tension between the cover and the valve platform so as to control the flow of liquid between channels. The cover includes an expansion area on the cover surface adjacent to the membrane and between the inlet and outlet. Liquid flows through the valve when it is drawn by a vacuum. The vacuum operates on both the flow path exit, but also above the membrane, lifting it to open the flow path. Discontinuance of the vacuum allows the membrane to seal the inlet and outlet, thus again preventing any flow between them.
