Plastic injection tool for producing a closure cap, and method for producing a closure cap
A plastic injection tool for producing a closure cap is divided into first and second mold halves that can be moved relative to one another and an injection nozzle is formed in the first mold half, and sliding jaw tool parts are formed in the second mold half, radially outside a central tool core, which can simultaneously be moved in an ejection direction of the produced closure cap and perpendicular to the ejection direction. A respective partial ejection contour of the cap body is formed in the sliding jaw tool parts. An ejector is also provided for ejecting the produced closure cap. Partial injection contours that are different from one another are formed in sliding jaw tool parts, and a sliding jaw tool part is in contact with the tool core in two regions lying after one another in the ejection direction, before the ejection of the closure cap.

Dispensing closure
A dispensing closure (40, 40A, 40B) defines a central axis and has a first body (54, 54A, 54B) for being located at an opening of a container. The first body (54, 54A, 54B) having a first peripheral wall (56, 56A, 56B) and a membrane (60, 60A, 60B) that is connected to the first peripheral wall (56, 56A, 56B) to initially occlude access to the interior of the container. The membrane (60, 60A, 60B) includes a separation member (62, 62A, 62B) that accommodates engagement by a user to separate the membrane (60, 60A, 60B) from the first peripheral wall (56, 56A, 56B) to permit access to the interior of the container. The membrane (60, 60A, 60B) has an annular peripheral portion (68, 68A, 68B) adjacent the first peripheral wall (56, 56A, 56B) that slopes axially outwardly along the central axis in a radial direction moving away from the first peripheral wall (56, 56A, 56B) toward the central axis.
COMPACT INJECTION MOULD FOR A CAP WHICH IS PREFERABLY PROVIDED WITH AN APPLICATOR SHAFT
An injection molding tool includes a \ primary mold cavity forming a handle sleeve having an inner circumference with an integral transition section attached thereto, and transitioning into a shaft protruding from the handle sleeve. The handle sleeve in an area between the attachment of the transition section and a free end facing the free end of the shaft has a skirt with an internally formed fastener for securing the handle sleeve to a container. The injection molding tool has an ejector-side insert and a nozzle-side insert removable for demolding purposes. The nozzle-side insert provides the part of the main mold cavity that molds the outer circumference of the handle sleeve, and the ejector-side insert.
TOOL FOR MANUFACTURING A CAP FOR A CONTAINER
A tool for manufacturing a cap for a container comprises a blade set that includes a plurality of knives. The knives are configured to make incisions in a cap having a main body having a top plate and a circular sidewall. The top plate has a top surface, wherein two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connects to one surface of the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end and a ring member, which is located at the opened end of the main body. There is a first tab on the ring member and a second tab on the sidewall.
Compression moulding machine and method
A compression moulding machine comprises: an extrusion unit configured to extrude a rod of pasty polymeric material; a cutting element, configured to portion the rod into individual charges; a rotary carousel, including a plurality of moulds, each mould being configured to receive a respective charge and to form a corresponding object from the charge; a feeder, configured to convey each charge to a respective mould at a feed position; an inspecting device, configured to capture inspection data, representing a composition of the rod or of the charges.
