Abstract
In at least some implementations, a blow molding apparatus provides that portions of the parison are engaged by one or more clamping devices disposed on or adjacent to the blow mold parts, and that the blow mold is opened whereby the parison is torn apart between the clamping devices, into two or more pieces of the parison. In other implementations, the clamping devices may be moved relative to the blow mold to tear the parison, or the parison may be torn by a combined movement of the blow mold parts and clamping devices.
Claims16
An apparatus for making a hollow body by way of a blow molding process, comprising:
- a parison for forming the hollow body;
- one or more objects adaptable for insertion within the hollow body;
- a blow mold with at least two parts having edge regions that are disposed in a complementary opposed relation to each other;
- and
- clamping mechanisms oriented toward an inner region of the blow mold and provided at the edge regions, each clamping device having a groove that is variable in its width by means of a clamping element that is moveable from an open position to a clamped position to engage part of the parison received within the groove;
- wherein one or both of the blow mold parts are movable relative to one another or at least one clamping device is movable relative to the blow mold parts, such that the parison is torn-between the clamping devices and the one or more objects are inserted therein.
