Apparatus for collecting solid or liquid wastes

Claim 1

In the known toilet apparatus for collecting solid or liquid wastes, in which one sealed end of a hose of thin, tight, flexible material is adapted to be passed down into a container for receiving the waste in a bag hose structure, while the other end of the hose is adapted to be passed over the upper edge of the container and is folded along a considerable length thereof and stored outside the container to provide a source of hose supply, the hose being adapted to be passed from its place of storage into the container when needed for use, and in which apparatus the container rests on a tubular support structure through which the hose is fed downwardly as required to an underlying collecting vessel and which apparatus is provided with a down-feed means which, unobstructed by the bulky waste-filled portion of the bag hose structure, is able to constrict and advance said hose downwardly a given distance, the apparatus also including a sealing mechanism for gripping and sealing the hose at least one position along the length thereof, the improvement which comprises: a. said sealing mechanism comprising at least two spaced apart welding jaws that are adapted to be moved toward each other in a cooperating fashion so as to press therebetween a portion of said hose and to seal said hose at one position along thereof by welding, b. at least one of said spaced apart welding jaws having incorporated therein a resilient head which resiliently deflects at least slightly during the interval of time that the welding jaws are gripping the hose therebetween.
