Abstract: A container for dispensing a two-component liquid comprises an outer resilient container for containing one component with a neck defining an opening and an inner tubular container. The inner container contains a piston slidably received within it. A closure member extends over the entire area of the inner container and closes its lower end. The piston and the inner container define a reservoir for containing a second component. The neck carries a closure cap which affords a liquid dispensing opening. A first non-return valve communicates with the liquid dispensing opening and with the interior of the inner container. An airflow path extends through the closure cap and the piston and includes a second non-return valve. The first non-return valve is arranged to permit liquid to flow from the inner container to the liquid dispensing opening and the second non-return valve is arranged to permit air to flow through the airflow path into the inner container.

Abstract: A dispensing valve for flowable material comprises a valve plate (26) of resilient polymeric material in which at least one elongate discontinuity is formed. The discontinuity defines at least one valve flap (28) which is an integral part of the valve plate but whose margin defined by the discontinuity is not connected to the adjacent material of the valve plate. The valve flap (28) is movable under the application of pressure from a closed position, in which the adjacent margins of the discontinuity form a substantial seal, to an open position, in which the margins for the discontinuity are spaced from one another and material can flow through the valve member. The polymeric material is a polyolefin material and the discontinuity is a rupture line. The margins defining the rupture line are of decreasing thickness towards their free edge and overlie one another.

Abstract: A beverage container comprises a bottle (2) and is sealed by a lid of resilient material. The bottle includes a neck (8) defining an opening and the lid includes a closure plate (32), integral with which is a depending skirt (18) extending around the outer surface of the neck. The skirt (18) carries an annular flange (20), which is in sealing engagement with the underside of the downwardly directed annular shoulder (14) on the outer surface of the neck. The annular flange (20) is connected to the skirt (18) by an integral hinge. The internal surface of the skirt (18) carries an annular protuberance (52), which is in sealing engagement with one side surface of the annular flange, the other side surface being in sealing engagement with the outer surface of the neck. The said one side surface of the annular flange includes an annular portion which extends downwardly and inwardly and is in contact with a corresponding annular portion on the surface of the annular protuberance (52).

Abstract: An applicator for applying a substance in liquid, paste or gel form comprises a container (2), of which a portion is flexible and which includes an applicator portion, which is arcuate in cross-section and in which one or more first apertures (14) is formed. An elastic valve membrane (18) is connected to and overlies the applicator portion and one or more second apertures (22) are formed in it. The first apertures (14) are offset from the second apertures (22). The valve membrane (18) normally engages the applicator portion and the first apertures (14) are thus normally closed by the valve membrane (18) but the application of pressure to the flexible portion of the container produces an increase of the pressure of the container which results in the valve membrane (18) being forced away from the applicator portion against its elasticity.

Abstract: A beverage container comprises a receptacle (2) which has a central axis (3) and is sealed by a lid (6) of resilient material. The receptacle includes a neck (8) defining an opening and the lid includes a closure plate (30, 32), integral with which is a depending skirt (18) extending around the outer surface of the neck. The inner surface of the skirt (18) carries a continuous annular flange (20), which is in sealing engagement with the underside of a continuous downwardly directed annular shoulder (14) on the outer surface of the neck and thus prevents movement of the lid in the axial direction away from the receptacle. The annular flange (20) on the lid is connected thereto by a resilient hinge connection (22). The annular flange (20) is elongate in axial sectional view.

Abstract: A drinking cap constitutes a one-piece molding of polymeric material including a first circular section tubular portion (2) for connection to the mouth of a beverage container and a second smaller circular section tubular portion (6) situated at least partially within the first tubular portion. The first tubular portion is connected to the second tubular portion by a resilient, annular, integral web (4), in which one or more flow openings (18) are formed. One end of the second tubular portion (6) is closed. The upper or external surface of the web (4) carries a projecting annular first sealing flange (20) at a point intermediate its ends, as seen in axial sectional view. The first and second tubular portion (2, 6) are coaxial and relatively movable in the axial direction between an open position, in which the flow openings (18) are unobstructed, and a closed position, in which the sealing flange (20) is in sealing engagement with the internal surface of the first tubular portion (2).

Abstract: A closure for a multiple component container includes an insert (12), a piston (20) and a cap (10). The insert (12) and the piston (20) define a reservoir and the insert (12) comprises a fixed cylindrical wall (26) and a movable wall (32) connected thereto and movable with respect thereto by the action of gas pressure within the reservoir. The movable wall (32) has a discharge aperture (36) formed therein. The cap (10) comprises a closure plate (14), integral with whose outer edge is a depending skirt (16), by means of which the cap may be secured to a container. The closure plate (14) cooperates with the piston (20) such that movement of the closure plate towards the insert (12) results in movement of the piston also in the same direction. The piston (20) forms a sliding seal with the internal surface of the fixed cylindrical wall (26). A valve member (22) is integral with, the piston (20) and is slidably received in and seals the discharge aperture (36).

Abstract: A drinking cap includes a first tubular portion (10) for connection to the mouth of a beverage container and an elongate actuating member (26) situated at least partly within the first tubular portion (10) and connected to it by a resilient, annular, integral web (12), in which one or more flow openings (28) are formed. The actuating member (26) is longitudinally movable in the axial direction between an open position of the flow openings (28) and a closed position thereof. The cap also includes an insert (6) and a piston (4) which together define a reservoir (56). The insert (6) includes a cylindrical wall (34) and a portion (40) which is movable under the action of pressure within the reservoir and in which a discharge aperture (44) is formed. A flow tube (52) is connected to the piston (4) around an aperture (50) and extends through the discharge aperture (44) in the insert (6) and forms a sliding seal with the edge (46) of the discharge aperture.

Abstract: A closure for a container comprises a circular closure plate (2, 4), integral with the outer edge of which is a depending skirt (8), integrally connected to the lower end of which by means of a resilient annular integral hinge (10) is an annular flange (12), which extends generally upwardly and inwardly. The closure also includes a cutter assembly which includes a cutting blade (38) and is mounted to rotate about the center of the closure plate (2, 4). The integral hinge (10) has a hole formed in it through which the cutting blade (38) extends. Rotation of the cutter assembly about the center of the closure plate thus results in cutting of the integral hinge (10) and thus in release of the closure plate (2, 4) and the depending skirt (8) from the annular flange (12).

The inner container (16) contains a piston (20, 22) slidably received within it. A closure member (18) extends over the entire area of the inner container and closes its lower (16). The piston and the inner container define a reservoir for containing a second component. The neck (4) carries a closure cap (10,12) which affords a liquid dispensing opening (38). A first non-return valve (24, 32) communicates with the liquid dispensing opening (38) and with the interior of the inner container (16).

Abstract: A liquid dispenser includes an outer tube (2) with a discharge opening formed in its side wall and an inner tube (4), which is at least partially accommodated within the outer tube and defines with it an annular space, which accommodates an annular sealing member (20), which forms a peripheral seal with the inner and outer tubes. The other end of the outer tube is adapted for connection to a liquid container. A liquid flow opening (30) is formed in the wall of the inner tube and the inner tube is movable longitudinally within the outer tube between an open position, in which the liquid flow opening communicates with the discharge opening (14), and a closed position, in which the liquid flow path is sealed. An air flow passage with two ends is formed in the inner tube, which is so arranged that when the inner tube is in the open position one of the ends communicates with the discharge opening and the air flow passage.

Abstract: An applicator for applying a substance in liquid, paste or gel form comprises a container (2), of which a portion is flexible and which includes an applicator portion, which is arcuate in cross-section and in which one or more first apertures (14) is formed. An elastic valve membrane (18) is connected to and overlies the applicator portion and one or more second apertures (22) are formed in it. The first apertures (14) are offset from the second apertures (22). The valve membrane (18) normally engages the applicator portion and the first apertures (14) are thus normally closed by the valve membrane (18) but the application of pressure to the flexible portion of the container produces an increase of the pressure of the container which results in the valve membrane (18) being forced away from the applicator portion against its elasticity.

Abstract: An insert for a multiple component container includes a reservoir with an opening defined by a peripheral edge which, in use, is connected to a sealing element (20). In use, the reservoir and the sealing element define a substantially sealed space. The reservoir includes a stationary portion (2) and a movable portion (4), which is connected to the stationary portion and is movable with respect thereto by the action of gas pressure within the reservoir. A discharge opening (6) is formed in the movable portion (4) and a gas leakage path is provided in the reservoir wall. A valve member (14) is connected to the stationary portion (2) and cooperates with the discharge opening (6) and substantially seals it. The application of a greater gas pressure to the interior of the reservoir than to its exterior results in movement of the movable portion (4) away from the stationary portion (2) and thus in the valve member (14) moving out of sealing contact with the discharge opening (6).
