CONNECTION SYSTEM FOR CONNECTING TO DEVICES WITH FLUID CONNECTION BETWEEN THE TWO DEVICES
The system (1) comprises a male part (2), a female part (4), a driving piece (24) having a spool portion (26) provided with a radial bore (28), a driving member (30) moving radially inside the radial bore (28), a cavity (34) and a radial projection (40). The driving piece (24) moves in translation between a disconnected position of the male and female parts and a connected position of the male and female parts. The driving piece (24) comprises a piston (48) sliding in an activation chamber (14) under the effect of a pressing force. The piston (48) is attached to the spool portion (26) in such a way as to move the drive piece (24) to one of the positions from the connection position and disconnection position under the effect of the pressing force. The system (1) further comprises means of control for triggering the application of the pressing force on the piston (48).
Mold insert for improved heat transfer
A mold block includes a tool body with a contoured finished surface adapted to receive a tool insert having a forming surface for forming a bottle neck in a molding operation. The tool body defines an internal channel for heat transfer with the forming surface. At least a portion of the channel is offset generally equidistant from the finished surface to provide a path contoured for conformal cooling of the insert. The tool body has a pair of ports intersecting the channel. Several methods for forming a mold block are disclosed and include machining a contoured finished surface adapted to receive a tool insert on a tool body, forming a heat transfer channel within the tool body, and forming a pair of ports into the tool body. At least a portion of the channel is offset generally equidistant from the finished surface for conformal cooling of the insert.
Lightweight container base
A container defining a longitudinal axis and a transverse direction that is transverse with respect to the longitudinal axis. The container includes a finish and a sidewall portion extending from the finish. A plurality of ribs are defined by the sidewall. A base portion extends from the sidewall portion and encloses the sidewall portion to form a volume therein for retaining a commodity. The base portion has a contact surface for supporting the container. A plurality of straps extend radially along the base portion away from the longitudinal axis in the transverse direction, each one of the straps defines a strap surface that is closer to the finish than the contact surface. The plurality of ribs and the base portion are configured to place the container in a state of hydraulic charge-up when top load is applied to the container after the container is filled.
MOLD BOTTOM WITH WIDE AIR VENTS FOR THE FORMING OF A CONTAINER
Mold bottom for the manufacture by blow molding of a container that has a bottom that is equipped with a seat, with this mold bottom including a unit that has a molding face bearing the at least partial impression of the bottom of the container, with a pressure-release air vent being formed in the unit and emptying out, via an inner opening, on the molding face and, via an outer opening, into a pipe for exposure to air, with this mold bottom also including an insert that is provided with at least one projection housed in the air vent and that has a terminal face bearing the impression of at least one part of the seat of the container, with this insert being provided with an inner circuit for heat regulation of the projection and being mounted to move in relation to the unit.
Lightweight Container Base
A mold system for forming a container having a longitudinal axis and a transverse direction that extends transverse to the longitudinal axis. The mold system includes a sidewall system for molding the sidewall portion of the container. The mold system also includes a base system for molding the base portion of the container. The base system is operable for forming the entire base portion of the container including a central pushup portion, a contact surface for supporting the container, and at least one strap extending along the base portion in the transverse direction. The strap defines a strap surface that is spaced offset in a direction parallel to the longitudinal axis from the contact surface. The strap surface extends in the transverse direction to be adjacent the sidewall portion such that the at least one strap surface is visible from a side of the container.
Resin container manufacturing apparatus, temperature adjusting device, resin container manufacturing method, and temperature adjusting method
A blow molding device in which a preform is injection-molded, the injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10 C. or more lower than the glass transition temperature of the preform.
Apparatus for controlling a tempering device of a blow-molding machine and method for controlling a tempering device of a blow-molding machine
An apparatus for controlling a tempering device of a blow-molding machine for tempering at least one blow mold member of a blow mold or a blow mold member carrier to a target temperature, with a device for receiving a temperature actual value of the blow mold member or the blow mold member carrier, where the temperature actual value is measured by a temperature measuring device in the blow mold member or the blow mold member carrier, devices for receiving a temperature target value of the blow mold member or the blow mold member carrier, analyzing the received temperature actual value and the received temperature target value, calculating a setting value for the tempering device from the received temperature actual value and the received temperature target value, and transmitting the setting value to the tempering device.
Process for fastening an accessory in a blow molded plastic tank
It is proposed a process for fastening an accessory to the interior of a blow-molded tank, the tank having a plastic wall produced from a parison, the accessory comprising a body having at least one attaching portion projecting radially from the body. The process comprises the steps of: a) introducing the accessory and the parison in a molten state into a mold so that the accessory is surrounded by the parison, the mold comprising cavities, at least one cavity being equipped with at least one movable insert configured to fold locally some of the molten parison on the attaching portion; b) contacting the parison with the attaching portion; c) moving forward the insert and folding locally some of the molten parison on the attaching portion; d) closing the mold by moving the mold cavities to a final closing position and inflating the parison to form the blow-molded tank; e) moving backwards the insert; and f) opening the mold.
Lightweight container base
A container defining a longitudinal axis and a transverse direction that is transverse with respect to the longitudinal axis is disclosed. The container includes a finish, a sidewall portion extending from the finish, and a base portion extending from the sidewall portion and enclosing the sidewall portion to form a volume therein for retaining a commodity.
