Abstract:
In a blow moulding machine for the production of plastics material containers, during a blow mould procedure, the container to be expanded is supplied with blow moulding air from a first gas preparation device on the one hand or from a second gas preparation device on the other hand. During this procedure a cooling of the base of the container is additionally carried out.
Abstract:
Plastic container with a base section, with a main body adjoining the base section in a longitudinal direction of the container forming an inner volume of the plastic container wherein the base section forms a plurality of standing foot areas, wherein a tension band extending in a radial direction is disposed between two adjacent standing foot areas, and the base section has a first curved structure with an injection point such that that the injection point projects in the longitudinal direction of the plastic container towards a mouth of the plastic container and a second curved structure adjoins the first curved structure outwardly in the radial direction, wherein this second curved structure is curved in the direction of the mouth of the plastic container, wherein a radius of curvature of the first curved structure is smaller, at least in sections, than a radius of curvature of the second curved structure.
Abstract:
A blow mould for forming plastic preforms into plastic containers, having at least two blow to mould side parts and a base part, which form a cavity, within which plastic preforms can be formed into the plastic containers by being acted upon by a flowable medium, wherein an inner wall of the blow mould side parts and of the base part having a contour which produces a predetermined shape of the plastic containers to be produced, wherein a plurality of openings being provided in at least one section of the base part, which openings allow a gaseous medium to be discharged during an expansion process of the plastic container. A ratio between a surface area of the base part and a surface area of the openings is 3-350, preferably 4-200, and particularly preferably 3-100.
Abstract:
Plastic container for beverages has a bottom region, a main body and a mouth. The bottom region has at least three supporting feet, wherein each of these supporting feet has at least one supporting region extending in the circumferential direction with respect to the longitudinal direction over a supporting region circumferential angle and each having at least one substantially flat, supporting surface for standing the plastic container upright, wherein at least one groove having a groove base acting as a tension band is arranged between two adjacent supporting feet. The groove base widens outwardly in the radial direction of the plastic container, wherein the at least three supporting feet are delimited in the circumferential direction by at least one foot side region in each case and in a radial direction toward the outside by a foot outer region.
Abstract:
A method for forming plastic preforms into plastic bottles has a first and a second operating mode, wherein the respective operating modes being selectively chosen by an operator as required. In in the first operating mode, i.e. a quality mode, a connection is established between a valve block and a pressure reservoir of the second pressure level in only one direction, from a valve block towards the pressure reservoir, i.e. a compressed air recycling mode, and in a second operating mode, i.e. an efficiency approach, a connection is established between the valve block and the pressure reservoir of the second pressure level in both directions, i.e. from the valve block towards the pressure reservoir and from the pressure reservoir towards the valve block.
Abstract:
A plastics material container, in particular for beverages, with an aperture by way of which a liquid is capable of being removed from the container, with a main body adjoining this aperture in a longitudinal direction and a base portion adjoining this main body in this longitudinal direction, wherein the base portion has at least three stand feet, wherein external surfaces of these stand feet in each case form a stand portion of the plastics material container extending in sections in the form of an annular segment over a pre-set circumferential angle and wherein at least three grooves are formed between these stand feet, wherein these grooves extend at least also in a radial direction of the plastics material container which is at a right angle to the longitudinal direction, wherein these grooves have in each case a groove bottom which extends at least also in the radial direction as well as a wall portion which extends at least also from this groove bottom to a stand portion of a stand foot adjacent to this groove bottom.
