Abstract: Inflatable plush toys are disclosed. The inflatable plush toys are made up of an outer cover and an inflatable inner bladder that is made of a substantially nonelastic film or sheet material. The inflatable bladder has substantially the same size and configuration of the outer cover whereby upon inflation the inner bladder fills substantially the entire interior of the outer cover. The outer cover and inflatable bladder can be made of a plurality of gores that are cut to desired size and then sealed together. The plush toys can have rather intricate shapes such as animal shapes, cartoon figure shapes and the like. A valve is disposed within the inflatable bladder whereby the bladder can be inflated with a suitable inflation gas such as air. In a preferred mode, the valve can be utilized to deflate the bladder whereby the object can be subjected to multiple inflation and deflation cycles.

Abstract: The present invention relates to a self-sealing refillable plastic balloon valve produced from at least two sheets of plastic film of equal size and shape, cut and heat sealed to form an elongated plastic fill having an operable channel between an inlet and outlet end. The elongated plastic fill valve being affixed to a plastic balloon stem interior and being capable of cyclic self-sealing and reinflation operation of the balloon body. The plastic balloon valve which is capable of multiple self-sealing and refilling cycles, functions through the use of internal self-sealing means either singly or in combinatoin. The self-sealing refillable plastic balloon valve is mounted within a balloon neck with the outlet end extending into the body of the balloon. During assembly of the balloon, the valve can be mounted within the neck in a manner such that the heat bonding does not close the interconnecting channel from inlet to outlet ends of the valve.

Abstract: A delay actuated explosive device for use in boreholes filled with high explosives is provided which comprises an explosive container having a detonator cord receiving conduit attached to the periphery thereof and a detonator receiving well which is offset from the detonator cord receiving conduit so as to avoid premature detonation. A detonator delay unit having an initiating means communicating with a delay detonator means is provided for use with the explosive container, the detonator delay unit being adapted such that the initiating means can be positioned proximate to the detonator cord conduit when the delay detonator means is positioned within the detonator receiving well of the explosive container.

Abstract: A container capable of withstanding pressures having a longitudinal cord-receiving groove and a detonator-receiving groove formed as integral parts of the container. Radially projecting, substantially deformable, grooves are formed on the container at its upper and lower portions to retain a substantially non-deformable tubular sleeve positioned on the container, thereby covering the cord-receiving groove and the detonator-receiving groove. The threaded cap for the container has a projecting member which forms with the interior side walls of the cap, an annular slot for maintaining a resilient, deformable gasket. Upon threadedly engaging the cap with the threaded neck of the container the projecting member protrudes into and is adjacent the interior surface of the neck and the gasket cooperates with the edge portion of the neck to form the improved seal for the container.
