Abstract
A discharging apparatus (1) is arranged in substantially completely inserted or plunged manner in a storage vessel (2) with a locking flange (30), which forms an opening (40) for the at least partial reception of the operating head (20) and engages round the vessel neck (7) in the manner of a hang-in profile. The locking flange (30) carries a securing body (50) for the snap retaining of closure cap lid. Thus, there is a very compact arrangement of the discharging apparatus (1) in such a way that the latter only insignificantly increases the total length of the storage vessel (2).
Claims34
A dispenser (1) for discharging a medium and for mounting on a vessel body (2) including a vessel opening (3) and reference surfaces (4-6), the reference surfaces 4-6 including an inner circumferential surface (6), an outer circumferential surface (5) and an outer end face (4) when mounted on the vessel body (2) said dispenser (1) defining a mounting position, said dispenser (1) comprising:
- a pump casing unit (12) linearly insertable through the vessel opening (3) into the vessel body (2), said pump casing unit (12) having an inner casing end (28) for disposition inside said vessel body (2) and an outer end (27) for disposition proximate to the vessel opening (3), said pump casing unit (12) enveloping an internal casing space, said casing space including a pressure chamber (15) in which the medium is pressurized, said casing space and said pressure chamber being disposed between said inner end (28) and said outer end (27) of said pump casing unit (12) defining an outermost unit circumference;
- an operating unit (16) moveable over an operating stroke with respect to said pump casing unit (12) for delivering the medium out of said dispenser (1) through a medium outlet (21);
- and
- mounting means (10) defining a mounting axis (11) and including a mounting flange (30), in said mounting position said mounting flange (30) being countersunk in the vessel opening (3) in relation to said outer casing end (27) of said pump casing unit (12), said mounting flange positionally holding said pump casing unit (12) in the vessel body (2) in said countersunk mounting position relative to the outer end face (4), said mounting flange (30) directly supporting and sealing said pump casing unit (12) on at least one of said reference surfaces (4-6).
A dispenser for discharging a medium comprising:
- a vessel body (2) including an opening (3) for receiving and storing a medium;
- a pump casing unit (12) axially inserted through the body opening (3) into the vessel body (2) and rigidly connected to said vessel body (2) in a mounting position, said pump casing unit (12) internally defining a casing space including a pressure chamber (15) for pressurizing the media;
- an actuating unit (16) displaceable over an operating stroke with respect to said pump casing unit (12) for delivering the medium out of said dispenser (1) through a media outlet (21), when in said mounting position said actuating unit (16) being manually accessible from outside the vessel body (2);
- mounting means (10) including a mounting flange (30) for positionally holding said dispenser (1) relative to said vessel body (2) when in said mounting position, and a cover (46) for covering said mounting flange (30) outside the vessel body (2), said actuating unit (16) and said vessel body (2) when mounted in a first covering state, said cover (46) being removable from said first covering state and returnable back to said first covering state without destruction, wherein said cover (46) includes a first holding member (51) for positionally securing said cover (46) with respect to said pump casing unit (12) in said first covering state, said cover (46) including a second holding member (54) apart from said first holding member (51) for positionally securing said cover in a second covering state separate from said first covering state, thereby providing holding means for alternately positionally securing said cover (46) either with said first holding member (51) or with said second holding member (54).
A dispenser (1) for connection to a container (2) for discharging a medium out of the container (2) when in a mounting position, the container (2) including a container opening (3) and a storage space (9) for the medium, said dispenser (1) comprising:
- a pump casing unit (12) including a pump casing (13) and a casing closure (14), said pump casing (13) and said casing closure (14) commonly directly bounding a hollow casing interior including a pressure chamber (15) for pressurizing the media, said pump casing unit (12) defining a longitudinally outermost casing end (27) and an inner casing end (28) remote from said outermost casing end (27), said inner casing end (28) being provided for receiving the medium from the storage-space (9),
- an actuating unit (16) operationally displaceable with respect to said pump casing (12) for actuating discharge of the medium through a medium outlet (21), and
- a mounting flange (30) for connecting said pump casing (12) to the container (2), said mounting flange (30) including at least one support leg (32-34) for direct support and sealing engagement with the container (2), said at least one support leg (32-34) being made in one part with said casing closure (14),
- wherein means are provided for substantially entirely immersing said pump casing unit (12) inside the container (2) when in said mounting position.
