摘要:
A container closure system comprising a threaded cap and a threaded neck wherein the cap is affixed to the neck by direct axial application so that the mating threads slip past one another and into engagement. The cap further includes sealing means to capture and constrict the outer diameter of the neck, and valve means to plug the container opening in the neck and expand the outer diameter of the neck, so that the sealing means and valve means cooperate to improve sealing of the cap and neck. The cap and neck further include tamper-indication means to prevent removal of the cap without activation thereof. The tamper-indication means includes a novel skirt, pull tab and membrane configuration. The container neck may include interrupted threads which do not traverse the parting line and an additional annular seal below the threads on the container neck.

A breathable, printable, washable wallcovering prepared by applying an aqueous coating composition to a glass fiber fabric. The composition contains a modified starch such as a phosphate ester of potato starch, a polymeric latex binder, a thickener such as polyacrylic acid, and optionally, a pigment and a cross-linking agent. The wallcovering is permeable to water vapor such that moist air can pass through and not accumulate between walls and the wallcovering.

摘要:
An assembly and method are provided for inflating a parison within a mold and forming the neck portion of a plastic container in a blow molding apparatus. The assembly includes a blow pin assembly mounted to a blow rod. The blow pin assembly includes an exterior surface having an annular cutting edge. The blow rod is movable along a vertical axis. The blow pin assembly is constructed such that at the time the mold is opened, the bottom end thereof is substantially incapable of engaging the lip of the blown container even if it is released unevenly from the mold. This is preferably accomplished by providing a blow pin assembly having a bottom end that is either above the shear steels at the time the mold is opened to release the container or has a sufficiently small diameter that it will not engage the container lip.
