Abstract: A can and easy open closure for the can which is structured and arranged to cooperate with the can such that as the closure is removed from the can, gas is allowed to escape while the contents of the can, such as a powder, is prevented from escaping.

Abstract: A thin walled, easily crushable container with an integral or seamed-on bottom is filled with an edible material which requires sterilization. The empty container has one end attached or integral that may have a concave slope relative to the inside of the container. A liquified or solidified inert gas is then inserted into the container. The container is then sealed with a concave shaped end before the inert liquified or solidified gas has completely vaporized. The ends are such that they do not bulge under the pressure left after sterilization, which pressure is due to the pressurization effect of the inert gas and which pressure is enough to overcome the vacuum caused by the cooling of hot water vapor or steam above the edible material and gives the can the required rigidity.

Abstract: A projectile for delivering to a target a can containing pressurized material which is to be dispersed over the area of target. In one embodiment, the projectile includes a cylindrical hollow housing to the rear end of which is attached a launching tube with a fin assembly. The can is slidably disposed within the housing. There is a space between a cap which closes the forward end of the housing and the can in the housing. The can slides forward in the housing toward the cap upon impact of the cap against the target. This opens a valve which releases the contents of the sealed can into the housing, and this, in turn, blows the cap off the housing so that the released material is dispersed over the target area. In another embodiment, the can itself has the launching tube and fin assembly attached to its bottom. Instead of being enclosed in a housing, the top of the can carries a cap which closes the top of the can and which cap is detented spaced away from the dispensing nozzle.

There is a space between a cap which closes the forward end of the housing and the can in the housing. The can slides forward in the housing toward the cap upon impact of the cap against the target. This opens a valve which releases the contents of the sealed can into the housing, and this, in turn, blows the cap off the housing so that the released material is dispersed over the target area. With the present projectile, the sealed can is not breached before the projectile strikes its target and the contents of the can may be dispersed in a very short time.

Abstract: The disclosure concerns a thonged medallion, method of assembling the same and apparatus for performing that method. The medallion includes a domed piece of metal having a flap bent into the interior of the dome, and the flap having a hook-like formation defined on the free edge thereof for cooperating with a hook-like formation on the opening in the element for clamping upon a thong inserted into the opening defined by the open flap. A continuous web of thong material is fed through a passageway into the opening in the dome-shaped element, a predetermined length of the web material is cut off, a stamping piston crimps the flap to clamp the thong in the opening.
