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 coordinated multi axis hinge arrangement provides a snap action between stable open and closed states. When the hinges operate between the stable open and closed states across a dead center position, resilient forces imparted by torsionally rigid connecting elements of the hinge to adjacent hinge parts such as body and lid elements are transferred by coupling or transmitting areas adjacent the bending regions or film hinges to remote resilient distortion or deformation energy storage areas. As the hinge passes a dead center position, this energy is in turn supplied and returned to the rigid connecting elements to impart snap action to the closure. The closure may be cast as a single piece of plastic material and may be cast in the open position.

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 bi-stable hinge unit (10) of elastic material connects two inflexible end portions (12, 13) to take up two stable positions on either side of an intermediate unstable position. The hinge unit (10) comprises two equal elements (14, 15), each of which having two cantilever arms (18, 20), linked to each other by two folding lines (22) acting as a "living" hinge. A triangular rigid plate (16) is arranged between and defined by said folding lines (22). The elements (14, 15) are arranged substantially parallel to each other with a distance therebetween and forming the main hinge line between said end portions (12, 13). By swinging the end portions (12, 13) toward each other along the main hinge line, the four cantilever arms (18, 20) will start to deflect and act as springs and the two triangular plates (16) will rotate through approximately 180.degree. in a plane normal to the elements (14, 15).

Abstract: A device for metering a fluid product comprises a closure cap threaded onto the nack of a container and acting on the stem of a valve member to lift the latter of a seat formed at the lower end of a cylindrical wall fixedly inserted into the neck of the container against the action of a resilient member.A metered dose of the product is dispensed by turning the container upside down and unscrewing the closure cap by then filled with the metered dose.In the inverted position the fluid product contained in the container flows into a chamber defined by the cylindrical wall via the opened valve member and a passage associated to the resilient element. The flow of the fluid product into the chamber is stopped by the engagement of the valve member with its seat as the closure cap is being unscrewed.In another embodiment, an intermediate element having a screw-threaded neck portion and a seat for the valve member is secured to an annular rim of a container.

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).
