Abstract: A hand operable pump device for pumping fluids includes a hollow body and an oval piston. The hollow body includes an inlet port and an outlet port. The inlet port is provided with a one-way valve permitting fluid flow into the pump. The outlet port is provided with a one-way valve permitting fluid flow out of the pump. The oval piston is designed to be pressed inwardly from an initial position by the hand, decreasing the volume of an oval chamber with a corresponding oval cross-section. The chamber is located within the pump and is fluidically connected with the inlet and outlet ports. The oval piston is further designed to return to the initial position when released, increasing the volume of the chamber.

Abstract: Sealing device for flexible liquid container is disclosed. In one preferred embodiment of the invention, the sealing device comprises an elongated member with a hollow passage extending through it with a longitudinal slot, slidingly mountable over a rod, which is provided over a lateral opening of a flexible liquid container. In another preferred embodiment of the present invention the rod is attached to the member extending through the passage. When the portion of the container provided with the lateral opening is folded over the rod, substantially overlapping an adjacent portion of the container and the sealer is slidingly mounted over the folded portion of the container, liquid is prevented from leaking out of the container through the lateral opening.

Abstract: A dispenser device for dispensing liquid form a bottle or container having a neck onto which a cap can be fitted is disclosed. The device comprises a cap adapted to be fitted to the neck, the cap provided with an opening; a drinking tube having a distal end and proximal end, the proximal end fluidically connected to the opening of the cap; and an adjustable feed tube having a proximal end and a distal end, the proximal end inserted into the proximal end of the drinking tube, the feed tube adapted to be moved at least partially in and out of the drinking valve and through the opening of the cap, so as to allow adjusting the length of the feed tube that is inserted inside the bottle.

Abstract: A bite valve for drinking liquids from a hydration system, the bite valve having a hollow deformable impervious body with a receiving opening fluidically connectable to an outlet of the hydration system for receiving liquids and a dispensing opening adapted to selectively dispense received liquids. A resilient piston positioned within the hollow deformable body, the resilient piston having a plug normally blocking the dispensing opening, and a resilient bifurcated member having a longitudinal dimension and a lateral dimension, adapted to shorten its initial longitudinal dimension when lateral force is exerted on its lateral dimension, and regain its initial longitudinal dimension when the lateral forces are not exerted, so when a lateral force is exerted on the resilient bifurcated member the piston is retracted inwardly allowing liquid to flow through the dispensing opening.

Abstract: A fast-strapping sandal assembly comprising a sole assembly having a ball, arch and heel area and inward facing and outward facing portions; a heel engagement strap, adapted to support a wearer's heel; a main strap having a first end and a second end, the first end engaged to the sole assembly at the ball area on the inward portion of the sole assembly, the main strap extending through a loop associated with a first support post attached to the sole assembly at the outward facing portion of the sole assembly on the ball area and/or arch area, crossing over through a loop associated with a second support post attached to the sole assembly at the inward facing portion of the sole assembly near the anticipated ankle position of the wearer; and a fastening strap engaged to the sole assembly at the heel area and fasteningly engageable to the second end of the main strap, whereby a single tightening and fastening of the main strap is required to acquire fast and precise firm hold of the sandal to the wearer&ap

Abstract: A mouthpiece for a hydration system designed for drinking liquids from that system. The mouthpiece comprises a body having an internal conduit passing through it, the internal conduit having a broad portion provided with a broad opening and a narrow portion provided with a narrow opening, a piston member having a distal portion and a proximal portion, the piston member provided with a passageway passing through it, the passageway having a first opening at the proximal portion and a second opening between the proximal portion and the distal portion. At least a portion of the piston member is inserted in the conduit fitting inside the broad portion while the distal portion of the piston member is adapted to fit inside the narrow portion. The piston member is adapted to coaxially move within the body. The mouthpiece further provided with an O-ring closely encircling the distal portion of the piston member.

Abstract: A flexible container for storing and dispensing liquids including an inner bag and at least one outer bag, and liquid dispensing means, wherein the inner bag is a collapsible impervious bag for dispensing liquid located within the outer bag, wherein the outer bag's longitudinal dimensions are smaller than the inner bag's dimensions such that at any given imaginary cross section, the inner bag's circumference at the imaginary cross section is greater than the outer bag's circumference at the same imaginary cross section, and wherein the outer bag is made of a substantially non-stretching flexible material, thus imparting the outer bag's high pressure and external impact durability properties to the inner bag.

Abstract: A sandal having a sole formed of a lower layer, an intermediate layer having openings formed therein, and a microporous upper layer with the layers sealed together to form air pockets. The sole is fastened upon a user's foot by three, separate, independently adjustable straps. One strap extends over the forward portion of the user's foot, and the other two straps loosely cross each other to extend over the front and rear of the user's ankles for securely holding the sandal in position upon the foot while allowing flexible and comfortable freedom of movement of the foot.
