Abstract: This invention relates to closing an open end of a pailette containing a biological element. The invention includes heating a dose of thermo-plastic material to a flowable condition and injecting the dose into the cold open end of the paillettes so that the material adheres to the inner wall of the paillette and solidifies to form a stable plug closing the end. The thermo-plastic material is preferably in the form of solid sticks. A valve in closing apparatus opens and closes communication with a reservoir containing the thermo-plastic material under pressure and defines a pre-determined volume for the dose. The invention is especially applicable to the production of paillettes for use in artificial insemination.

The position and shape of the stopper are stabilized by a film applied by sealing to the outside of the closure hole. The walls of the container are flexible to accomodate changes in pressure inside the container.

Abstract: A self-packaged medical device has a hollow body and an operative element inside for controlling the dispensing of fluids from the device. A handle, partly inside and partly outside of the body is connected to the operative element and is provided with a frangible seal at the point where the handle passes through a hole in the wall of the body. This seal allows maintenance of cleanliness of the interior of the body during storage, but does not interfere with the use of the handle to operate the element within the body once the seal is broken. The seal is formed by a continuous, frangible film adhering to the body and the handle, and is broken by motion of the handle, whereupon the device is ready for use. A hydrodermic syringe is desirably self-packaged in this fashion.A method of making a self-packaged hypodermic syringe includes assembling a piston, with a piston rod connected to it, into a bore of a tubular barrel so that the rod extends out of the barrel.

Abstract: A hot melt composition is used to form a closure liner, e.g. the circular, integral, gasket-like member adhered to the periphery of a circular top or closure for a food jar or the like. The hot melt composition is selected to have, in the solid state, sufficient deformabilty, resiliency, hardness, lubricity, and other requirements of closure liners.
