Abstract:
A process for producing hollow plastic receptacles, comprising the steps of:simultaneously forming a group of hollow receptacles from a tubular member of heat-sealable plastic in a single mold such that the hollow receptacles are positioned side by side and each receptacle is formed in two halves which are welded together; forming fused seams on marginal portions of the member to provide at least one marginal waste segment along with fused seams; forming at least one closed hollow body simultaneously with and similarly to the receptacles in the marginal waste segment spaced from and attached to the hollow receptacles by the fused seams, and shaping the at least one hollow body to form a frame surrounding the group of hollow receptacles; and removing the group of hollow receptacles and the hollow body joined thereto from the mold; whereby the receptacles and hollow body form a relatively stable and rigid article which can be reliably removed even before complete cooling of the article.
