A blow mold assembly is disclosed having removable neck insert mold components for forming features of a container for engaging a removable container closure and manually operable retention devices for releasably retaining the neck insert mold components with mating mold components of the mold assembly. Advantageously, each manually operable retention device includes a clamp mechanism movable between a release position and a clamp position by manual operation and the clamp mechanism is effective to resist forces acting on the clamp to move the clamp to a release position when the clamp is in the clamp position. Each manually operable retention device is retained with an associated mating mold component when a neck insert mold component is removed from or installed to the mold assembly.

Provided is a hollow mold which can improve the manufacturing efficiency for a hollow mold including a protrusion. Ventilation duct 3 (hollow mold) includes main body part 20 including hollow part 30 therein, and protrusion 33 protruding outward from main body part 20. End surface 51 of main body part 20 and end surfaces 53 and 55 of protrusion 33 are flush with each other. A cutting operation is linearly performed along the end portion of main body part 20 to the end portion of protrusion 33 in plan view, whereby removal of burr 61 of protrusion 33 to form the end surface is efficiently performed.

The invention relates to a method for producing a container (2) from a thermoplastic, having at least one surround (4), provided in the container wall (1), for a container opening. The surround (4) comprises a structure behind which parts of the container wall (1) extend and/or which is penetrated by said parts. The method is carried out using a multi-part blow mold that has at least two mold parts, each having at least one cavity, wherein the surround is placed as an insert in the cavity (10) of the blow mold (7). The method comprises pressing the preform that has been forced into the cavity (10) into the structure of the surround (4) by means of a tool which is brought to bear on the preform (12) on the side of the preform facing away from the cavity (10).

Disclosed is a mold for forming a deep grip container, the mold having drive mechanisms opposably to drive moveable inserts into the mold. The drive mechanisms may be located entirely within the mold and may include a slotted cam. Also disclosed is a method of manufacturing a blow molded bottle with a deep pinch grip comprising: providing a mold hanger having an outer envelope and providing within the outer envelope a drive mechanism to drive moveable inserts into the mold after blowing molten plastic into contact with the mold. Further disclosed is a blow molded bottle with a deep pinch grip manufactured according to the disclosed methods.

In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

An invention including a bottle container of a pinch-grip type of synthetic resin blow-molded product and which includes a body of a bottle container, and a grip including a pair of right and left deep-recessed grip portions, formed by concaving both side wall portions of the body of the bottle container, a rear wall portion of the body disposed at a position rearward from the deep-recessed grip portions in a front-back direction, wherein each grip portion includes a caved in recessed wall, vertical side walls positioned facing each other across the wall, and lateral walls disposed at upper and lower ends of the wall, so that surrounding walls as a whole is formed by vertical walls and lateral walls that surround the recessed wall, and wherein the vertical side walls have an angle of gradient which is set at a right angle relative to a transverse center line extending horizontally.

The invention relates to a container (1) for receiving a liquid content, comprising a container wall (10) which surrounds a container interior (12) and comprises an opening (8). The container wall has an opening region (2) at the opening, a base region (4) arranged opposite the opening region, and a lateral region (3) which extends between the opening region and the base region, and the container wall has a dimensionally stable central region (22) in the base region and a flexible flat region (24) which encircles the central region. The container wall transitions from the central region into the flat region at an angle such that an edge (26) which encircles the central region is formed in the container wall between the central region and the flat region. The invention further relates to a blow mold (31) for producing such a container.

A blow-molded stackable receptacle comprises a first blow-molded component defining a first blow-molded component axial opening at a first end and an axial recess at a second end, wherein the axial recess is defined by a longitudinal wall comprising at least one ridge or tab and a second blow-molded component defining a second blow-molded component axial opening at a mating end, wherein the axial recess of the first blow-molded component is configured to receive the mating end of the second blow-molded component, wherein the at least one ridge or tab is configured to retain the mating end of the second blow-molded component. At least one method is further disclosed.

Disclosed is a molding unit for the forming of a container provided with a hollow recess, this molding unit including: a mold provided with a lateral wall defining a cavity and provided with a pocket that comes out into the cavity; and a boxing device. The boxing device includes: an insert mounted in translation relative to the lateral wall between a retracted position in which the insert is retracted into the pocket, and a deployed position in which the insert projects into the cavity outside of the pocket; an actuator integral with the insert and provided with a piston; and an added sleeve, mounted in a complementary recess made in the lateral wall and attached to it, and in which the piston is mounted in translation.

Disclosed is a molding unit for the forming of a container provided with a hollow recess toward the interior of the container, this forming unit including: a mold provided with a lateral wall defining a cavity having the impression of at least one part of the container and incorporating a fluid circuit for thermal regulation of the wall, which comes out on an upper surface of the mold; and a boxing device. The boxing device includes: an insert mounted in translation relative to the lateral wall; an actuator integral with the insert; and a pneumatic circuit for controlling the movement of the piston, which includes at least one primary duct for supplying the chamber, which comes out on the upper surface of the mold.
