Abstract: The invention is directed to a closure moulded in closed position. The closure comprises a body and a lid, which are separated by a circumferential gap. A snap hinge comprising two trapezoid elements which are connected each by film hinges to the body and the lid, causes a snap action while opening or closing the closure. The closure offers opening angles in the range of 220°.

Abstract: A closed injection moulded plastic closure (20) having a first closure part and a second closure part (22). The first closure part is connected to the second closure part by snap-on hinged connection. The first and second closure parts have no main hinged connection with each other, but are connected to one another by two connecting elements and four hinged connections bordering the two connecting elements on nonadjacent sides. Coupling elements may serve as an original warranty seal for indicating opening for the first time. If required, a catch and a counter-element serve as a locking mechanism and prevent unintentional opening of the closure.

Abstract: A resilient hinge arrangement has a first hinge part and a second hinge part that assumes a plurality of stable pivoting positions with respect to the first hinge part, with a dead center lying at least between two of the stable pivoting positions. The second hinge part is arranged to return from pivoting positions between the two stable pivoting positions through the dead center, outside a dead center itself, in an elastically resilient manner into a nearest one of the stable pivoting positions. Two connecting arms are spaced a distance apart and include at least one coupling element protruding movably from each of the first and second hinge parts, and at least one substantially flexurally rigid intermediate part between the coupling elements that is delimited by two bending regions that are spaced apart and arranged at an angle to each other between the intermediate part and the coupling elements.

Abstract: The closure (1) consists of a tubular base portion (2) and a cap (3). Considered in the direction of the axis (17) of the base portion (2), in the closed position the outer contour of the cap (3) is within the interior contour of the base portion (2). Cap and base portion are connected to each other in a single unit by a snap hinge and injection molded in a closed position. Extending from the snap hinge, cap and base portion are additionally connected together by a safety strap (40), which is to safeguard against unintentional premature opening of the closure (tamper evidence). The closure enables a marked productivity increase during manufacture.

Abstract: A rotary cover for closing the axial opening of a hollow-cylindrical body, a rotary cap and said body having corresponding cam threads, which cause an axial displacement of the rotary cap relative to the body when the rotary cap is rotated. Axial sides of the rotary cap and of the body, which face each other, extend in a plane inclined by a specific angle .alpha. relative to the axis of the body. These axial sides of the rotary cap and of the body are in alignment with each other in the closed position of the rotary cover.

Abstract: A hinge apparatus is disclosed, in which at least two flexible strips (1-3) are articulated, each via two articulation grooves (7, 8), to two parts (5, 6) that are movable relative to one another and are substantially cylindrical in embodiment, in such a manner that upon a relative movement of the two parts with respect to one another out of one stable position into the other stable position, the flexible strips are located in a substantially radial plane of the two parts (FIG. 3a).
