Abstract: A captive screw closure with a tamper-evident band and a screw cap captively connected thereto is disclosed. The screw closure includes an outer surface with an internal thread and an upper surface. The mechanical strain on the retaining bands are substantially reduced. This is achieved by the screw closure having at least one pulling element which permits a pure axial longitudinal movement of the screw cap to the tamper-evident band in the direction of the longitudinal axis of the screw closure. The screw closure includes a pivoting element, in particular a pivoting plate, connected either fixedly or pivotably to the tamper-evident band. The pivoting element, in particular the pivoting plate, is detachably connected to the screw cap. The pivoting element, in particular the pivoting plate, may be connected to the screw cap in a fixed but pivotable manner.

Abstract: A supraglottic tube is provided, which despite certain softness has high compressive strength in the proximal distal direction and an adjustable radius of curvature. The supraglottic tube includes at least three lumens. A guiding lumen is located between a respiration lumen and a esophageal lumen. The lumens are separated from each other by separating walls. A guiding means, which includes a pressure element and a tractive element, is located in the guiding lumen. A tractive force can be applied to the tractive element by way of a feed connector and an adjustment unit, in which the pressure element is supported, whereby the radius of curvature of the supraglottic tube can be adjusted.

Abstract: A plastic closure including a bottom part and a lid that has an annular retaining bead in the bottom part. A disk having a support surface is held positively or non-positively in the bead. The disk includes one or more through-passages, which open into a chamber. A thixotropic fluid present in a flexible container reaches the chamber through the through-passages, where the fluid performs a directional change from axial to radial and after a second directional change from radial to axial flows out through the spout opening, wherein a constriction between the two directional changes accelerates the flow.

Abstract: A plastic closure for dispensing thixotropic fluids from a flexible bottle. The closure has a bottom part including a cover surface with a spout opening Beneath the cover surface a support surface in which several axially extending through-passages are disposed, which are radially offset relative to the spout opening. The support surface includes partial elements in the form of tongues, which are integrally formed on an annular jacket wall by way of integral hinges which engage in a pin in the installed state. This results in a closure that can be manufactured particularly inexpensively, is simple to install, and can be produced in one piece.

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: The invention discloses a supraglottic tube, which despite certain softness has high compressive strength in the proximal distal direction and the radius of curvature can be adjusted. For this purpose, the supraglottic tube comprises at least three lumens. A guiding lumen is located between a lateral respiration lumen and a further lateral esophageal lumen. Said lumens are separated from each other by separating walls. A guiding means, which comprises a pressure element and a tractive element, is located in the guiding lumen. A tractive force can be applied to the tractive element by way of a feed connector and an adjustment unit, in which the pressure element is supported, whereby the radius of curvature of the supraglottic tube is adjusted and it can be better introduced into the patient in the bent state and thereafter the radius of curvature thereof can be adapted to the anatomy of the patient or the position of the patient, thereby maintaining the sealing pressure of the larynx mask around the larynx.

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: The invention relates to a larynx mask comprising a dorsal cover plate with an inflatable cuff integrally formed thereon and a tube connecting connector to a plug region having an adjoining insertion section for connecting to an insertion tube. Two separate lumens are provided in the region of the insertion section, these being the esophageal lumen and a respiration lumen. Said two lumens are separated from each other by a separating or supporting wall. Said separating or supporting wall runs from the insertion section to the tip of the larynx mask. While the esophageal lumen opens into the esophageal outlet at the proximal end, the respiration lumen opens in the ventral direction, while the lumen is closed in the proximal direction close to the tip. Such a larynx mask can be produced in one piece by way of injection molding and at the same time is reinforced by the separating or supporting wall to prevent kinking.

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: A larynx mask comprises a cover plate having a peripheral cuff adjoining thereon and is provided with a tube insertion connector at the distal end, while the tip has a special design at the proximal end. The cover plate ends in the region of the tip on the cuff, or even before that, and the esophageal passage runs as an open channel over a constricted region of the cuff. Said channel preferably comprises a widening and is delimited on both sides by reinforcement means, which are preferably formed by reinforcing walls or additionally as reinforcing ribs. Said design of the lead-through of the esophageal passage results in a considerable reinforcement of the proximal tip of the larynx mask and therefore counteracts possible kinking of the tip.

Abstract: A plastic closure including a bottom part and a lid that has an annular retaining bead in the bottom part. A disk having a support surface is held positively or non-positively in the bead. The disk includes one or more through-passages, which open into a chamber. A thixotropic fluid present in a flexible container reaches the chamber through the through-passages, where the fluid performs a directional change from axial to radial and after a second directional change from radial to axial flows out through the spout opening, wherein a constriction between the two directional changes accelerates the flow.

Abstract: The invention relates to a plastic closure (1) for dispensing thixotrope fluids from a flexible bottle. Said closure has a bottom part (2) comprising a cover surface (4) with a spout opening (5). Beneath the cover surface (4) a support surface (12) is provided, in which several axially extending through-passages are disposed, which are radially offset relative to the spout opening (5). The support surface (12) comprises partial elements in the form of tongues (24), which are integrally formed on an annular jacket wall (20) by way of integral hinges (25), which engage in a pin (22) in the installed state. This results in a closure that can be manufactured particularly inexpensively, is simple to install, and can be produced in one piece.
