A cap (1) for a container comprises: 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 (3) is joined to the cap body (2), 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), wherein the cap (1) comprises a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40).

A toothed shaft can be installed in a hollow shaft that has an internal toothing such that the toothed shaft is coupled in a positively locking fashion so as to be telescopic in a direction of a longitudinal axis. The toothed shaft may include a toothing region with teeth on an outer circumference and extending in an axial direction. In the toothing region a shaft core may be overmolded by way of an injection molding process with a sliding coating comprised of thermoplastic material. The sliding coating may have at least three impressions, with each of the at least three impressions featuring an aperture that extends through the sliding coating to a surface of the shaft core.

An undercut processing mechanism is attached to and used in a molding die for forming a molded product having an undercut portion, and allows demolding of the undercut portion. The undercut processing mechanism includes: a holder attached to or formed integrally with the molding die; a sliding piece configured to be slidable relative to the holder such that a mold core is moved so as to demold the undercut portion; a retaining piece configured to retain the sliding piece such that the sliding piece is slidable; and a support wall configured to support the sliding piece so as to prevent the sliding piece from being tilted when the sliding piece slides. The sliding piece forms a part of the mold core for forming the undercut portion.

A mechanical interlock pin assembly includes a shaft having a first end and a second end. The mechanical interlock pin assembly includes a set of helical spline elements disposed at the first end of the shaft, the set of helical spline elements extending along a longitudinal axis of the shaft. The mechanical interlock pin assembly includes a bearing rotatably coupled to the second end of the shaft, the bearing configured to allow rotation of the shaft between a first rotational position and a second rotational position relative to a mold cavity.

Provided is a sliding mechanism capable of moving a slider in at least two different directions with a simple structure. The sliding mechanism includes a guide body including a guide unit configured to guide a slider in predetermined directions; and the slider is guided by the guide unit to move in the predetermined directions. The predetermined directions at least include a first direction and a second direction which are different from each other, and the guide unit at least includes a first guide unit configured to guide the slider in the first direction and a second guide unit configured to guide the slider in the second direction.

The disclosed embodiment is related to a manufacturing method of a die-formed 3-dimensional plastic impeller of a centrifugal pump and the impeller manufactured thereby, including a mold for twisted blade and a mold for impeller outlet, the mold for twisted blade is configured to form a twisted blade portion of each blade of the impeller, the mold for impeller outlet is configured to form a rear portion of each blade, a hub rim part of the impeller, and a shroud rim part of the impeller so that the hub rim part, the shroud rim part, and the blades are formed in a single piece at the same molding process.

A basket assembly is provided. The basket assembly includes a molded basket body having opposed side walls with minimal draft angles. The basket body defines a front opening for receiving fluid and items, an interior area of receiving and holding the items, and a plurality of perforations for allowing the fluid to escape the interior area while retaining the items within the interior area. The perforations are placed, oriented, sized, and configured to maximize fluid flow and item retention while the basket assembly is positioned in flowing fluid of a washing machine wash tank. Support pins retain the basket assembly at the top of the wash tank and handles extending therebetween facilitate removal of the basket assembly from the wash tank.

A method produces an elastically deformable molded part having a number of undercut molded-part regions, by use of a mold. To provide a technique which makes it possible to produce individual molded parts which are elastically deformable and have undercut regions from soft materials in a precise and cost-effective manner, a method is performed in which a molded-part material is introduced into the mold. The mold has a shaping contour with a number of special contour regions, which are configured for shaping the number of undercut molded-part regions of the molded part, and in which the molded part is removed from the mold by at least partially deforming the mold together with the molded part therein in such a way that the molded part elastically deforms and the mold at least partially, but in any event to the extent of the special contour regions, breaks up.
