A package closure (10) comprising a neck (12), a cap (11) for closing an opening of the neck (12), and a folded portion (21) connecting the neck (12) and the cap (11), wherein the neck (12) has an axis (A) and is formed with a tubular portion (16) and an inward projecting sealing flange (18), wherein the cap (12) is formed with a top portion (13) for covering the opening of the neck, and an axially extending sealing ring (19) to interact with the sealing flange (18) to form a seal between them. The neck (12), the cap (11) and the folded portion (21) are formed in a single integrated piece. The cap (11) is further formed with an axially extending wall (14) arranged radially outside of the tubular portion (16) of the neck (12), wherein the folded portion (21) connects the wall (14) of the cap (11) with the neck (12). The top portion (13) of the cap (11) is connected to the wall (14) through a breakable notch (23) and a hinge (24), wherein the top portion (13) is openable by tearing along the notch (23) and folding along the hinge (24). Disclosed is also a method for producing the package closure (10).

A molding apparatus that injection molds an opening device on a packaging material sheet includes first and second molding units to injection mold a wall portion of the opening device on the sheet; the first molding unit comprising first and second molding elements configured to cooperate in contact to delimit at least part of a mold cavity fillable with molten material for forming a pull-member of the opening device; the mold cavity being delimited at least by first and second surfaces defined by the first and second molding elements respectively; a third molding unit cooperable with the first and second molding elements to delimit the mold cavity, and defining a third surface, facing the first and second surfaces and delimiting, together with these latter, the mold cavity; the third surface is shaped to be equidistant from the first and second surfaces when the first and second molding elements cooperate.

A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

An in-mold lid closing apparatus comprises a frame, a first actuation assembly configured to linearly position a lid engagement member between a first and second linear position relative to an in-mold lid, and a second actuation assembly configured to rotatably position the lid engagement member between a first and second rotational position relative to the in-mold lid. The first actuation assembly comprises a first support moveably coupled to the frame and a first actuator coupled to a frame support of the frame and a first actuator drive element coupled to the first support. The second actuation assembly comprises a second support moveably coupled to the frame and disposed between the frame support and the first support and a second actuator coupled to the second support and a second actuator drive element coupled to the first support.

A method of making a vehicle interior panel having a molded-in airbag door includes cutting a hinge layer of the panel while the hinge layer is supported in a panel molding tool. The hinge layer can be in the form of a reinforcing net and is cut along a perimeter of the airbag door away from the airbag door hinge. The cutting occurs in the molding tool either before or after molding material is introduced into the mold cavity. The cutting also occurs before, during, or after the molding tool is closed from an open condition. A cutter of the molding tool is either stationary or moveable with respect to the portion of the molding tool from which it extends.

A mold, system and method for manufacturing a part includes injection molding a substrate in a single injection mold and optionally trimming the panel substrate. The substrate can have a first configuration or a second, different configuration. Trimming of the substrate can occur when the substrate has the first configuration to define an aperture in the substrate.

The present invention relates to a pressure relief element (11) to be used as an overpressure safety means in devices where a gaseous medium must be rapidly released in case of overpressure, wherein the pressure relief element (11) has at least one notch (9) which is designed as a predetermined breaking point where the pressure relief element (11) breaks at a certain level of overpressure, thereby irreversibly opening an exhaust path for the gaseous medium. The present invention also relates to a pressure relief device of an electrochemical battery, comprising such a pressure relief element and a battery comprising such a pressure relief device.

To provide a method for the production of components, in particular wheel well liners of vehicles, in which the component is produced in a spread out or unfolded form and at a later time is moved into a curved or folded form, wherein in an area of a bending point, a material strength of the component decreases as compared to a material strength of the adjacent area, it is suggested that the minimum thickness of the material in the area of the bending point is molded to be 40% to 60%, preferably 45% to 55%, more preferably about 50% less than the material strength of the adjacent area.

A plastic cap, which is a highly producible one-piece type cap when molded, but becomes a two-piece type cap excellent in sealability and openability when used, and enables a small-diameter pouring opening to be formed, is provided. The plastic cap comprises: a cap body which is composed of a top plate section and a skirt section, has a pouring nozzle formed on an outer surface of the top plate section so as to surround an opening-scheduled portion, and is fitted and fixed to a container mouth; and a top lid composed of a top face, and a circumferential wall suspending from an outer peripheral edge of the top face. The top lid has, formed therein, a protrusion protruding downward from an inner surface of the top face and having an engaging portion on an outer surface thereof. The cap body has an inner plug formed therein. The inner plug is composed of an annular sidewall having an outer diameter enabling the annular sidewall to intimately contact an inner surface of the pouring nozzle; and a bottom formed at a lower part of the annular sidewall. The inner plug is formed integrally with the cap body via a breakable weakened portion at a position below a seal portion of the pouring nozzle having an inner diameter enabling the seal portion to intimately contact the inner plug. On an inner surface of the annular sidewall, an engaged portion vertically engageable with the engaging portion of the protrusion is formed.
