摘要： A mold for blow molding has a base component for forming at least one portion of a concave base of a container and comprising a mounting plate having connections for supply and return of a heat transfer fluid, a body having a molding surface thereon and having a substantially cylindrical recess having a roof spaced from the molding surface, a substantially cylindrical insert comprising a diverting surface, an inlet passage therethrough and open to the diverting surface and an outlet passage therethrough, the diverting surface spaced from the roof and side of the recess so as to define a cavity and a drain therefrom open to the outlet passage. In a method of blow molding turbulent flow is induced in heat transfer fluid conducted through the base component from impact with the roof and the turbulent flow is dispersed within the cavity over the diverting surface whereby heat transfer from the molding surface is enhanced.

摘要： A blow molded container formed of a polyester resin for use in hot fill applications. The container includes upright side walls, an integral base and a preselected outwardly thermoelastically deformable portion. Upon being filled with a liquid at an elevated temperature, the deformable portion of the container deforms outwardly to partially increase the volumetric size of the container. The remaining portions of the container generally shrink in response to being hot filled.

摘要： Apparatus for shaping a tubular preform into a hollow body in which an axially directed wall of the preform primarily comprises oriented and/or crystallized plastic material. The tubular preform (10d) is fixed in a circumferential region (13d) in the vicinity of the mouth edge (14d) of the preform between mechanical forming devices (30,40), after which the devices, during continued clamping of the circumferential region, are displaced in the axial direction of the preform relative to a mandrel (50). Thus, the mandrel is displaced into the preform during simultaneous expansion thereof and the material is oriented and/or crystallized. In a preferred embodiment, there is compensation of the stretching forces, which arise in the material when inserting the mandrel, by applying a force to the bottom of the preform by a bottom support (75).

摘要： In a blow mould firstly a convexly formed bottom is blown. An intermediate region lying between an axially displaceable bottom mould and the blow mould bears on mould portions which on introduction of the bottom mould are pivoted back for turning back the bottom region to form a stand ring and release the path for the bottom mould which is finally positioned on the blow mould so that a closed mould cavity is formed on which the transformed bottom region can be reliably applied by blow pressure.

摘要： A method for producing a container from a tubular blank of polyethylene terephthalate or similar material, according to which a polyethylene terephthalate blank is stretched at least approximately 3-fold to produce a preform (20). In an axial section through the preform, the contour length substantially corresponds to the contour length in an axial section through the final container. The preform (20) is heated to a temperature above the glass transition temperature (TG) and is converted to the container (21) in a blow mold (12). In doing so, the contour length of the material is maintained through successive reduction of the axial length of the body (23) which the preform constitutes during the conversion to the container. In order to achieve this, the base portion of the blow mold (11) is moved towards the orifice (22) of the final container. The container acquires a neck portion (23) and a container body (26) which are axially oriented, in the case of polyethylene terephthalate to an extent corresponding to about a 3-fold monoaxial stretching, while the container body (26) is also transversely oriented, in the case of polyethylene terephthalate to an extent corresponding to about a 3-fold stretching as a maximum. The wall thickness of the container is inversely proportional to the radius of the container. The container is dimensionally very stable and has excellent strength characteristics.

摘要： In a blow-moulding process, the base of a hollow plastics body is formed initially of convex configuration and then a portion of the base is deformed inwardly to provide a concave area surrounded by an annular support surface. Deformation of the base is controlled in response to an increase of pressure in the mold cavity after termination of venting thereof.

摘要： This invention relates to a method of making a blown plastic container having a concave pressure bottom configuration by blowing a pre-form into a container having a flat bottom, then contacting and deforming the flat bottom to reform the flat bottom into the desired pressure bottom configuration. The flat bottom is reformed by blowing, or by mechanical contact, or both blowing and contact, at a temperature conducive to multi-axial orientation to provide a pressure bottom of increased strength. To facilitate the performance of the method utilizing an initial parison formed by free extrusion, the present invention further contemplates smoothing out any pinch flash and distributing it on the bottom of the parison, so that the pinch flash will not interfere with subsequent forming of the bottom of the final container as above described.
