Method of extrusion blow molding using a liquid
A method of making a container via a simultaneous filling and forming of the container with a liquid product is disclosed. The method comprises the steps of extruding a parison (12, 2), capturing a portion of the parison (12, 2) within a mold (15), and inflating the captured portion of the parison (12, 2) against the mold (15). The captured portion of the parison (12, 2) is inflated against the mold (15) by introducing the liquid product into an interior of the captured portion of the parison (12, 2), wherein the liquid product forms an end product to be sealed within the resultant container.
FLEXIBLE INNER SOCKET FOR PROVIDING INNER CIRCUMFERENCE REDUCTION TO RIGID PROSTHETIC SOCKET
A flexible prosthetic inner socket that resides inside of a rigid prosthetic socket that is fabricated by forming a sized, injection molded, flexible inner pre-socket. The flexible inner pre-socket includes a body formed with an opening and an enclosed end. The Pre-socket can be heated and stretched over a prosthetic residual limb model and then a prosthetic rigid socket can be formed over it. It can also be heated and vacuum-formed inside of an existing hard prosthetic socket in order to provide global volume reduction intended to make the rigid prosthetic socket fit tighter onto the residual limb. The opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.
Trouble recovering method of aseptic filling machine and aseptic filling machine

A door of a chamber in which the trouble occurred is opened while a pressure in the chamber other than the chamber in which the trouble occurred is kept positive, the trouble is removed and then, the door is closed, an inside of the chamber in which the trouble occurred is cleaned as necessary, the inside of the chamber is sterilized and then, the operation of the aseptic filling machine is resumed.
Method and apparatus for processing plastic containers with speed-controllable blow moulding machine
The invention relates to a method for processing plastic preforms (10) and/or plastic containers (20) by means of at least one first processing apparatus (2), which processes the plastic containers (10, 20) in a first specified manner, and by means of at least one second processing apparatus (4), which processes the plastic containers (10, 20) in a second specified manner and which is arranged before or after the first processing apparatus (2), wherein the plastic containers (10, 20) are transported from one processing apparatus (2, 4) to the other processing apparatus (2, 4) by means of a transport apparatus (5) and the at least first processing apparatus (2) and the at least second processing apparatus (4) are coupled to each other, the first treatment apparatus (2) is a blow-molding machine (25) for shaping plastic preforms (10) to form plastic containers (20), and the process speed of the blow-molding machine (25) is defined by means of a specification, which contains a plurality of process parameters that are characteristic of the shaping process. According to the invention, the process parameters associated with at least one further process speed are at least partially determined on the basis of at least two key specifications, such that the adaptation of the process speed of the blow-molding machine (25) to a speed of at least one further processing apparatus (2, 4) is enabled and/or adjustment of the speed is possible.
Blow molding method, blow molding mold, and blow molding apparatus
A blow mold method for a double-walled container, including: blowing in which an intermediate molded article is molded by stretch blowing a preform housed in a die; and pressing in which the intermediate molded article is pressed inside the die and a double-walled container is molded. During the pressing, an internal floor-corresponding section is pressed such that internal wall-corresponding section is inverted as far as the inside of an outer wall-corresponding section, in a state in which heat retention is maintained such that the internal wall-corresponding section can be inverted as far as the inside of the outer wall-corresponding section.
Method and device for filling containers with carbonized filling material and subsequently closing the filled containers
The method relates to a method for filling a container (13, 32) with carbonized liquid filling material and for closing the filled container, in which the filling material is introduced in a filling station (10, 30) by a filling head (11, 33) at defined filling pressure into the container (13, 32), wherein the filling head (11, 33) is firstly moved from an idle position, which permits supplying and inserting a container (13, 32) into the filling station (10, 30), into a working position toward the inserted container, in which an end region (16) of the filling head seals off the opening (14) of the container, the container (13, 32) is then filled, the filling head (11, 33) is moved after completion of the filling phase back out of the working position into an idle position spaced apart from the container (13, 32) and the container (13, 32) is then closed in the filling station (10, 30) using a cap (20) at least enough that filling material can no longer escape, and the container (13, 32) is then removed from the filling station (11, 33), characterized in that before the movement of the filling head (11, 33) from the working position into the idle position spaced apart from the container (13), an overpressure lying between the ambient pressure and the filling pressure is set in a pressure chamber (15) of the filling station (10, 30) surrounding the opening (14) of the inserted container (13, 32), which overpressure is selected in such a way that possible foaming up of the filling material located in the container (13, 32) is minimized enough that filling material does not escape from the container (13, 32) when the filling head (11, 33) is raised out of the working position after the filling procedure.
Method for inverting the base of a plastic container, device for implementing same and use of the device
The invention relates to a method for inverting the diaphragm of a filled and capped container. According to the invention, the container is placed on a support ring of an inversion device, a pressing member is applied to the container and a pusher is raised through the support ring to invert the diaphragm and shape the diaphragm into an arch. While the pusher inverts the diaphragm, the seat is moved away from the upper plane of the support ring, so that when the pusher reaches the raised position, a space is opened between the seat and the support ring to enable a longitudinal expansion of the container under the combined effect of the increase in internal pressure caused by the decrease in the volume due to the inversion and the forces generated inside the container by the pusher and the support member.
