    Abstract: The present invention provides a hollow container that enables the suppression of permeation of the content of the hollow container to the outside. A hollow container 1A includes a hollow container body 2A and a sub-component 3A. The hollow container body 2A has an opening 2a in its wall. The sub-component 3A is inserted in the opening 2a and is in contact with an outer surface of the wall at a contact portion 2c of the container body 2A to seal the container body 2A. The container body 2A is made of multiple layers including an intermediate barrier layer 2x. The wall of the container body 2A is thinner at a circumferential edge portion around the opening 2a as a thinner portion 2b than at the contact portion 2c where the sub-component 3A is in contact with the outer surface of the wall.

  • Patent number: 8408893
    Abstract: An apparatus for molding plastic preforms into plastic containers may include at least one blow molding station having a cavity. Within the cavity, the plastic preforms may be expanded into plastic containers. The blowing station has a bottom portion which delimits the cavity. The bottom portion is detachably disposed on a carrier by a fastening mechanism. The fastening mechanism has at least one pin-like body disposed on a first fastening element. The pin-like body engages in a condition in which the bottom portion is fastened to the carrier in a groove which is provided in a second fastening element. The pin-like body is displaceable relative to the carrier in the groove for fastening the bottom portion, and the groove is designed in such a way that an end section of the pin-like body may pass through the groove in a first section of the groove and cannot pass through the groove in a second section of the groove.
