A Molding unit for the forming of a container includes: a mold provided with a side wall defining a cavity bearing the impression of a portion of the container; an insert having a frontal surface bearing the impression of a local portion of the container, movable between a retracted position and a deployed position, with this insert being penetrated by ducts; a pierced piston to which the insert is attached and which ensures the mobility of the latter between its retracted position and its deployed position; and at least one pierced screw by which the insert is attached to the piston.

A blow molding machine suitable for manufacturing the bottle having the handle and a method for using the same, wherein each of the preform holders has a local temperature regulating device, the local temperature regulating devices are disposed around the handle portion, the rotary joint supplies liquid or gas continuously to the local temperature regulating devices of the preform holders to perform continuous temperature regulation for the handle portion, thereby overcoming the problem that the temperature needs to be immediately cooled after the injection molding, and temperature of the body portion can be maintained, so as to achieve the purpose of reducing energy consumption.

Disclosed is a molding unit for the forming of a container provided with a hollow recess toward the interior of the container, including: a mold provided with a lateral wall defining a cavity having the impression of at least one portion of the container, provided with a housing formed hollow in a protrusion forming a projection toward the interior of the cavity and opening into the cavity; and a boxing device having an insert mounted in translation relative to the lateral wall between a retracted position in which the insert is retracted in the housing, and a deployed position in which the insert projects outside of the housing, a projection whose transverse extension is less than or equal to 85% of the cumulative transverse extension of the protrusion and of the insert.

A Molding unit for the forming of a container includes: a mold provided with a side wall defining a cavity bearing the impression of a portion of the container; an insert having a frontal surface bearing the impression of a local portion of the container, movable between a retracted position and a deployed position, with this insert being penetrated by ducts; a pierced piston to which the insert is attached and which ensures the mobility of the latter between its retracted position and its deployed position; and at least one pierced screw by which the insert is attached to the piston.

A mold body (10) for a blow mold (1). The mold body (10) has a bottom region (14), a shoulder region (13), a central region (15) and a separating plane (12). At least one mold cavity (11) has an inner wall (111) situated in the mold body (10). At least one temperature control channel (30) is arranged in the mold body (10). The at least one temperature control channel (30) is situated and/or positioned in the mold body (10) in such a way as to remove more heat from or supply more heat to a first region (112) of the inner wall (111) than a second region (113) of the inner wall (111) that is adjacent to the first region (112).

A method for forming a container with an integral handle includes heating a preform having an integral handle in a first oven, stretching the preform, closing a first mold having a first mold recess and a second mold having a second mold recess around the preform, and blowing air into the preform. A handle pocket wedge block is inserted into a handle pocket of the integral handle of the preform within the first mold and the second mold.

A stretch blow moulding system for PET containers with PET integral handles: the containers blown from injection moulded preforms: each preform having the integral handle projecting from a junction point on a body portion of the preform: containers blown in a continuously rotating stretch blow moulding machine of the system. In a preferred form the preforms are progressed continuously at a substantially constant speed: the containers blown therefrom progress at the same substantially constant speed through to the filling and capping machine: and wherein the containers progress continuously through the filling and capping machine at the same substantially constant speed. Also described is a continuous stretch blow moulding system applied to specified integral handle PET preform and PET blown container structures stretch blown from the preforms thereby to obtain variable wall thickness of the preforms and/or variable wall thickness of the containers.

A tubular molded body that can reduce restrictions on attachment to another member to be easily attached to another member. The tubular molded body 10 includes a tube main body 11 formed in a tubular shape and an attachment flange 100 formed in a flange shape to project from the tube main body 11. The attachment flange 100 includes a thin-walled hinge 130 and is rotatable by the hinge.

In a method, an article of unitary construction is blow molded and integrally provided with a clip for securement to another item. The clip has an arm initially blow molded into an open elevated configuration. The arm is pivotable into closed and open configurations. When closed, the arm is in selectively releasable and secure engagement with a catch on the article. The arm is biased towards the catch. When open, the arm is depressed relative to and biased towards the closed configuration. The open configuration is traversed to secure the article to the item. In the open elevated configuration, the arm is elevated relative to the closed configuration. The arm is preferably a carabiner-type arm. The article is preferably formed of a composition of matter including polyethylene and plastic additives to provide the arm with sufficient pre-built tension to stay in the aforesaid selectively releasable and secure engagement.

The invention relates to a plastics connecting seam for the fluid-tight connection of at least two plastics surfaces. The plastics connecting seam is in the form of a plastics connecting seam that supports strength under a load in such a way that a load acting in a standard load direction increases the connection strength of the seam.
