Provided is a method and device for batched compression molding of rubber and plastic products by means of multiple mold cavities, including alternate operation of a blank shuttle and a male mold that is in a bottle cap mold, being controlled by means of engagement of two incomplete gear sets. Mold opening motion, isostatic pressing energy storage, and spring energy storage are implemented by means of the engagement characteristic of the incomplete gear sets, and mold closing and compression molding are implemented by means of the non-engagement characteristic, isostatic pressing energy storage, and pressurization of the incomplete gear sets. The method and device effectively resolve the general problem of low production efficiency and poor precision and stability of existing compression molding cap manufacturing equipment.

The controller is configured to transmit a first drive signal to the first actuation assembly and a second drive signal to the second actuation assembly to drive one of a linear position and a rotational position of the lid engagement member and to adjust at least one of the first drive signal and the second drive signal based upon a first feedback signal received from the first actuation assembly and a second feedback signal received from the second actuation assembly.

Provided is a method for performing AC optimal yield control within an inverter that includes a plurality of DC power sources configured to supply DC power, a plurality of converters to convert direct current power to alternating current power to be supplied to a load, a plurality of short-circuit protection devices connected to a DC interconnection bus at the DC power sources, and configured to provide short-circuit protection, a plurality of current sensors configured to sense circulation current at the short-circuit protection devices, and a controller. The controller controls the converters and monitors the circulation current sensed along the DC interconnection bus via the current sensors, and when power reduction occurs at one of the DC power sources, performs a closed-loop control current operation to controllably increase the circulation current along the DC interconnection bus to be greater than an impairment lower limit of the short-circuit protection devices.

A method for making a cap (1) for a container comprises a step of forming in a mould, in which the following are made: a body (2) configured to be coupled and uncoupled relative to the neck of the container and including an internally threaded side wall (21), which extends around a longitudinal axis (A), and a transverse wall (22); a tamper evident ring (3), including a retaining element (31), configured to engage a locking member on the neck of the container, and a joining portion (32), where the tamper evident ring is joined to the cap body, the joining portion (32) being configured to be torn along a perimeter surrounding the longitudinal axis (A) in response to a movement of the body (2) away from the tamper evident ring (3); a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40), the film (400) being adjacent to a first flank (43) and a second flank (44) of the connecting band (40), each of the first flank (43) and second flank (44) extending from a first end (41) of the connecting band (40) connected to the retaining portion (31) to a second end (42) of the connecting band (40) connected to the side wall (21) of the body (2), along the whole length of the first (43) and of the second flank (44).

The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

A cap for closing a container for administering a medication includes a pot-shaped body having a cavity with at least one or more openings and a base plane for delimiting the cavity at least in some regions. The cap also has at least one septum. The body has a dome with an end-face opening closed by the septum. The dome protrudes from the base plane on the base plane face opposite the cavity. The septum is inserted into a receiving area of the dome under pretension.

An apparatus comprises a mould part having a forming chamber and a filling device for filling the forming chamber with a mouldable material. The filling device comprises an entry duct for a flow of mouldable material and air and a preliminary chamber communicating with the forming chamber. The entry duct opens into the preliminary chamber in a position such as to send the flow of mouldable material and air towards the forming chamber with a helicoidal movement, so as to separate the mouldable material from the air.

A system (200) for making a fitted cap (300) comprises a fastener template (202), dimensionally identical to a portion (106) of a fastener (100) and extending from a support plate (210), and a first plurality of through-openings (212) penetrating the support plate (210) and arranged about the fastener template (202). The system (200) also comprises a precursor cap (320) that is geometrically complementary to the fastener template (202), first means (217) for heating a first polymer sheet (270), and second means (219) for applying suction to the first polymer sheet (270) through the first plurality of through-openings (212) to vacuum-form the first polymer sheet (270) over the precursor cap (320). After vacuum-forming the first polymer sheet (270) over the precursor cap (320), at least a portion of the first polymer sheet (270) forms the fitted cap (300). The fitted cap (300) is configured to apply a shaped sealant shroud (590) to the portion (106) of the fastener (100).

A dispensing closure for a product container includes a plastic closure body having a top wall with a dispensing opening which is arranged in line with a dispensing passage of the container. The closure includes a self-closing valve embodied as a membrane made of a plastic foil. The membrane has a valve portion, which in use can assume an open position under influence of product pressure, and an attachment portion surrounding the valve portion. The attachment portion of the valve is sealed to an annular support surface integrally formed in the closure body along the periphery of the opening or being formed on a plastic annular insert part that is connected to the closure body along the periphery of the opening. The seal between the attachment portion and the support surface includes an annular groove and an inner annular seal zone adjoining the annular groove on a radial inner side.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and an outer layer coupled to the lid.
