Abstract:
A packing system for liquid foodstuffs or pharmaceutical preparations, comprising disposable portion packs containing the liquid foodstuff or pharmaceutical preparation. Each pack comprises an openable opening means. The packing system is characterised by a reusable connecting means which is made separately from the opening means and which, in the open state of each opening means, is connectible to the same and through which the liquid foodstuff or pharmaceutical preparation is dischargeable from the respective pack. Each connecting means is made in the form of a sealed protrusion which is openable by cutting or the like and which is formed in one piece with two opposite side panels of the pack, and which in its open state forms a duct-like opening communicating with the interior of the pack. The present invention also relates to a connecting means and a container included in said packing system, as well as a method for connecting such a connecting means to such a container.

The disclosed device comprises a body having an engagement part for engaging with the opening of the closure receptacle; a cover having a discharging route communicating with the opening by a discharging aperture and a cylinder protrusively formed in predetermined length from a substantially center of the body to provide an opening groove and closing groove on the outer periphery, respectively; and a sliding member having a slide body which a stopper is formed in the inner periphery thereof so as to alternatively couple with the opening groove and closing groove, a protruded sealing bar on the center of the slide body to form the discharging route and to open and close the discharging aperture alternatively by sliding it along the outer periphery of the cylinder and a discharging portion provided in slide body so as to communicate with the discharging route and discharge the contents out of the closure receptacle.
Abstract:
The invention relates to a plastic closure comprising an upper closure part (1) and a lower closure part (2), which when in use form two separate parts (1, 2). Both of said closure parts (1, 2) are connected as a single component to each other via a hinge (7) or joint hinge (7), thereby allowing rotation of the closure parts (1, 2) about 180 DEG . In said non-closed position, the closure is quickly injected as a one component part. The hinge (7) or joint hinge (7) is connected via predetermined breaking points to one or both closure parts (1, 2). The hinge or joint hinge can be detached from the said closure part(s) by hand and therefore serves as a tamper-proof seal.
Abstract:
A liquid dispensing container (10) of the squeeze bottle type has a low center of gravity liquid bottle (12) with a hemispherical base portion (12a) and a frusto-conical neck portion (12b). A spout assembly (14) is coupled to an upper end of the neck portion for dispensing liquid when a deformable bottom wall (12d) of the base portion of the bottle is flexed. The spout assembly includes a bottle cap (16) with a through bore (18) in which a flexible dispensing tube (20) is slidably extensible and retractable to dispense liquid, such as lubricating oil, into locations that would otherwise be inaccessible. A wiper element (22) in the bottle cap associated with the through bore provides a liquid impervious seal between the bottle cap and the tube and ensures that excess liquid on the outer surface of the tube is scraped off as the tube is extended. A nozzle (24) is connected to a distal end (20b) of the tube and a pop-up sealing cap (30) is slidable back and forth over the nozzle to selectively open and close a dispensing hole (26) in the pop-up cap.
Abstract:
A dispensing closure (1) incorporating a flexible, self-closing valve (5) and a transport seal for preventing accidental dispensing of product through the valve during transportation and storage of a filled container. The closure includes a cover (4), which is adapted to move axially between raised and lowered positions, to actuate the transport seal. The transport seal comprises a sealing plate (8), located between the valve and the container opening, which partially occludes the container opening but defines at least one dispensing orifice (9). To form the transport seal, the cover is lowered so that it presses part of the flexible valve against the sealing plate around the dispensing orifice/s, thereby blocking the dispensing passageway to the valve.
Abstract:
A bottle (1) having a container (5) and a specially formed neck (9) having a flange (13) with a downwardly sloping portion (15) and which is spaced form the container (5) to create a recess (17) between the flange and the container. The bottle cap (3) has an inner shell (19) and an outer shell (21). A sealing surface (27) moves longitudinally within the inner shell. The outer shell is preferably flexible and has prongs (31) facing inwardly to move outwardly when the outer shell is compressed by a person's fingers. Other embodiments lack a separate inner shell and employ different operation of the prongs to retain the cap. In one case, rotation of the cap brings these prongs beneath a set of blind slots which engage the prongs and restrain their upward motion. Another embodiment allows the prongs to pass through slots to engage the underside of the flange. Further embodiments have a pressure release button (41) built into the cap and a protective cap (43) placed over the outer cap.
Abstract:
A closure suitable for mounting onto a container. The closure includes a main closure having a top portion having an aperture therethrough and a skirt portion depending downwardly from the top portion and adapted to attach to the container. A spout extends upwardly from the top portion and defines a bore that is in fluid communication with the aperture in the top portion. A plug member having a radially outer surface is mounted to the spout and extends at least partially across the bore. A top cap is mounted to the spout and has an upper portion that has an inner surface defining an opening through the upper portion, the opening being in fluid communication with the bore of the spout. The top cap is relatively movable between a first position where the plug member is at least partially within the opening and at least a second position where the plug member is withdrawn from the opening. Prior to the plug member firstly entering the opening in the upper portion of the top cap, an annular sealing rib extends inwardly from the upper portion at least partially across the opening to a free edge. The inner surface of the opening has an internal diameter relative to the external diameter of the plug member such that when the plug member at least firstly enters the opening, at least a portion of the sealing rib is engaged by the plug member and folded back towards the inner surface of the opening to form a seal between at least the outer surface of the plug member and the top cap.
Abstract:
The invention concerns a push-pull closure comprising: a base (1) provided with an internal thread (6); a valve lifter (2) associated with the base (1) and mobile relatively to said base (1) between a closing position and an opening position, a cap (3) covering the valve lifter (2) before the closure is opened for a first time. The invention is characterised in that the closure comprises a tamperproof inner seal welded on the top part of the valve lifter (2) and providing evidence of first opening as well as matching sealing means before it is first opened.
Abstract:
Insulated drink bottle has an outer cylindrical casing (3) and an inner cylindrical lining (2) leaving an insulating cavity between the outer casing (3) and the inner lining (2). A cap (11) is screwed to the body of the bottle and sealed by an O-ring (6). An opening (13) is formed in a recess (1) of the cap (11) and the opening (13) is sealed by a plug (14) that is formed as an integral part of a moulded plastic spring member (4) with leaf spring portions (16) and mounting means (17) for securing the spring member (4) into the body of the cap (11). The spring member (4) incorporates first cam means with an inclined surface (18) for movement of the plug (14) against the biasing action of the leaf spring (16). A plunger (7) operable by a resilient button (5) is mounted in the cap (11) to permit transverse movement of the plunger (7) relative to the lid. The plunger (7) incorporates second cam means with an inclined cam surface (19) at one end of the plunger (7) to engage the inclined cam surface (18) on the spring means (4). Transverse movement of the plunger (7) across the cap (11) causes the first cam means (18) to slide down the inclined second cam means (19) causing the plug (14) to be moved downwardly against the biasing action of the spring (16) allowing liquid to pour through the opening (13).
