A dispensing cap is moved into engagement with the flexible means and the dispensing cap and flexible means are moved away from the neck opening while propellant is then injected through the neck opening into the region between the inner and outer containers. The dispensing cap is moved into the neck opening and crimped into engagement therewith to fix the position of the flexible means and inner container while maintaining a space between the neck opening and a portion of the exterior surface of the dispensing cap during crimping.

Abstract: Apparatus is provided for packing articles, for example apples and other readily damaged fruits, in a close-packed array. A first feeder operates to pack a first supply of the articles in spaced-apart groups and a second feeder operates to fill the spaces between these groups. The feeders are preferably rotary members rotating in a vertical plane and having circumferential depressions. These depressions cooperate with peripheral confining barriers, eg. belts, to carry the articles downwardly and release them as required. The packages for receiving the articles, preferably pieces of expanded structural honeycomb material, may be carried under the feeders by a movable, synchronized conveyor. This conveyor may have protruberances for holding the honeycomb material expanded during filling. Unloading may be effected by raising the filled package into a confining frame in which it is then moved for deposition in a carton.
