Abstract: An apparatus for opening sealed packaging, including three parts, a pouring nozzle having a flange, a cylindrical cutting element and a screwcap. According to this invention, all three parts of the apparatus are produced in one piece as a semi-finished product. The teeth of the cutting element protrude into the pouring nozzle, while the screwcap is held on the flat edge of the cutting element. The three parts are connected to one another via predetermined breaking point bridges. This invention reduces the production costs and simplifies the assembly and the systems which are required for this purpose.

Abstract: A semi-finished product for the rational manufacture and assembly of a two-part closure of a spout element and of a screw cap. The spout element and the screw cap are manufactured as one piece in a coherent manner via breakage bridges. Tooling costs for injection mold tools are thus saved, and the assembly of the closure of the semi-finished product is simplified because of the defined, radial alignment of both parts.

Abstract: A pouring nozzle with a flange and an internal thread and an external thread, and also a cutting element having an upper rim and a lower rim formed with teeth. A screw cap with catches acts on catches of the cutting element. To make fitting easier, the cutting element and the pouring nozzle are produced as a one-piece semifinished product, wherein the cutting element is connected to the lower rim by weakened bridges so that the lower rim of the cutting element lies in a plane with the upper rim of the pouring nozzle and the teeth are protected in the pouring nozzle. This structural design allows an easy fitting which also reduces the reject rate.

Abstract: At least one cutting element on a closure having a spout and a screw cap, which can be screwed thereon and which has a tamper-evident band. The tamper-evident band is joined to a lower edge of an outer wall of the screw cap via specified rupture location bridges. The at least one cutting element outwardly projects through an intermediate space. When the screw cap is unscrewed for the first time, the at least one cutting element cuts through the specified rupture location bridges. A distance between the tamper-evident band upper edge and the lower edge of the screw cap is provided with a measure whereby enabling the distance to be surmounted only occurs once all specified rupture location bridges are cut through.

Abstract: A closing device for a container having a bung-type lower part with a cylindrical pour spout. The cylindrical pour spout has a female thread in which a cylindrical piercing element that is open to both sides and that has a male thread is retained by a screw connection. A screw cap can be placed on the lower part. The screw cap has a driver that interacts with a driver in the piercing element. A fine-pitch thread is between the screw cap and the lower part and a coarse-pitch thread is between the lower part and the piercing element. The combined screw/translational motion of the piercing element and the selected threads produce a highly effective cutting motion.

Abstract: A two-part hinge closure having a lower part which has a surrounding outer wall and which can be placed on a container, and has a cap which has an outer wall and which can be joined to the lower part in a hinged manner. The lower part and the cap are separately produced and can be assembled together. In an assembled and closed state, the outer walls are situated above each other in an aligned manner, at least in the hinge area of both hinge closure parts. Both closure parts can be joined to one another by a snap hinge having at least one spring element and at least one coupling piece. When the closure is in a closed state, the at least one spring element and the at least one coupling piece are at least almost aligned with the outer wall of the closure part on which they are formed as one piece.

Abstract: A closing device arranged above a pierceable point of a closed container including a lower part with a cylindrical discharge nozzle, a screw cover and a piercing element. The piercing element, which is open on both sides, is displaced downwards in an axial direction in a screw-like manner in a screw cover in the lower part of the closing device. The piercing element has two cutting elements offset at an angle which produce a continuous, interconnected cutting line, and a displacing element which shifts a partially cut-out tab of the container from a region of the discharge nozzle.

Abstract: Screw caps with guarantee strips are known. Usually, such guarantee strips are torn off by means of a tab or the guarantee strip encompasses an edge on the container and all of the predetermined breaking point links are torn in their longitudinal direction when the cap is unscrewed. According to the invention, radially projecting parts are provided on the container or its pouring opening (2) in the form of positive closing means (11, 12) which engage in corresponding recesses (13, 15) of the guarantee strip on the screw cap and prevent mutual twisting. Twisting on the screw cap results in a shearing movement being exerted on the predetermined breaking links (6), which have little resistance against these forces.

Abstract: A pouring device for two individual, mutually connected containers include in each case a sealing bung on each container neck. The sealing bung has a pouring outlet and an incoming air orifice. Pouring elements, which each includes a chamber, are disposed above the sealing bung. A pouring orifice and an incoming air orifice issue into each chamber. A single connection line leads off from the chamber to a corresponding pouring outlet. The pouring elements can be attached to the container necks. A cover is placed over the pouring element and includes a thread bung onto which it is possible to screw a threaded over including a sealing part mounted therein.

Abstract: Plastic snap-on hinged closures each having a bottom part and a cap that are attached to each other by a snap-on hinge tend to tear on the lateral borders. This is due to the geometry of closures having a round or oval shape when viewed from the top since only the flexibility of the outer walls have been used so far. This unresolved problem can be solved by a curvature with varying height and wall thickness extending along the joint. The curvature is elastic when pressure is exerted in the middle and when pulled from the sides.

Abstract: A closing device located on a container of laminated paper, over a predetermined opening. The device has a lower part with a pouring opening and a cover closing the opening. A push-piece for breaking open the predetermined opening is provided in the lower part. The push-piece is joined to the lower part by a snap hinge, making the device more user-friendly and ensuring that the laminated paper predetermined opening does not obstruct the pouring opening area.

Abstract: A device for pressing of tablets from a blister pack. The device has a base plate and a cover plate. When closed, the two plates connected to each other by a hinge are superimposed in such a manner that openings in the cover plate are arranged substantially over openings in the base plate. The base plate is arranged using fins at a distance from a datum plane. Supporting bumps and embossed edges form a support plane on which the blister pack rests with the cover film thereof, for facilitating punching through the cover film when pressure is exerted on bumps of the deep-drawn plastic film of the blister pack. Tabs with corresponding locking noses lock the device. The device also allows disabled patients to remove the tablets required from the blister pack without further assistance.

Abstract: A transport and processing apparatus for a two-component material, in particular for bone cement, has a liquid component (1) and a powder component (2) which are separated by a membrane (3) and each occupy a transport chamber (4, 5) in a closeable container (6, 7) which has an expulsion piston (8) at one end and an opening (9) for the expulsion of mixed two-component material at the opposite end. The transport chamber (4) for the liquid component has a ring shape and a central aperture (34) for expelling the mixed two-component material through the aperture (34). The membrane is destroyed by a relative movement between the transport chamber for the liquid component (1) and a solid body (12, 17) enclosed in the container in order to effect a flow of the liquid component (1) into the transport chamber (5) for the powder component (2) and to enable the mixing with a mixing piston (11).

Abstract: The surgical clip (1) with an approximate C-shaped cross-section has two lateral jaws (10) interconnected by a web (12). The two jaws (10) end in pressure edges (11) which thus define a clamping gap (15). There is a centric recess (13) perpendicular to the direction of the two pressure edges (1) roughly in the middle, passing through the web (12) on the one hand and partly through the two jaws (10) below it. This design makes it possible to stack the surgical clips of the invention and secure them on a storage unit. This makes it possible for the first time to apply surgical clips in rapid sequence by means of a simple fitting device. There are inwardly directed retaining ribs (17) on the inner surfaces (16) of the jaws (10) to position the clips on the storage unit.
