[0001] Adapter and dispensing valve for an aerosol can

[0002] Field of technology to which the invention relates

[0003] The invention relates to special devices for dispensing the contents of a package and is a transition device and a metering valve for an aerosol can.

[0004] State of the art

[0005] Currently, dispensing devices with replaceable cartridges / containers for the active ingredient (AI) are widely used (e.g., RU 190573, published 04.07.2019, RU 221039, published 16.10.2023, RU 219167, published 30.06.2023). In particular, various designs of such replaceable cartridges / containers are known (e.g., RU 220879, published 09.10.2023, RU 215267, published 06.12.2022). However, the known systems are not adapted to work with replaceable cartridges in the form of aerosol cans.

[0006] Various designs of dosing devices for aerosol cans are known from the prior art (for example, US6041967, published 03 / 28 / 2000, US6840461B1, published 01 / 11 / 2005), including at least a valve configured to be connected to an aerosol can, a pressing element, as well as inlet and outlet elements that ensure the passage of the contents of the aerosol can when the pressing element is acted upon.

[0007] The drawback of such solutions is their inability to connect to the standard dispensing nozzle design, which includes a housing and a push-button cap and is used in common dispensers. Known designs are complex and require modifications to accommodate common dispensing devices and replaceable cartridges / containers.

[0008] The technical problem is that the known designs of dispensers for aerosol cans are characterized by a complex design that does not allow for the use of a standard design of dosing nozzle used in common dispensers.

[0009] Disclosure of the essence of the invention The objective of the present invention is to expand the scope of possible application of a standard design dosing nozzle, in particular to ensure the use of aerosol cans as containers in common dispenser designs without making changes to the design of the aerosol can or dispenser.

[0010] The technical result allows the use of a standard-design dosing nozzle as part of a dosing valve with an aerosol can. The standard-design dosing nozzle includes a housing that secures the nozzle to the container containing the active ingredient, and an associated push-button cap that transmits pressure to the active ingredient transfer unit, which may include a pump. However, using an aerosol can eliminates the need for additional equipment, such as an active ingredient transfer unit, since the active ingredient will be delivered under pressure within the aerosol can itself.

[0011] The above-mentioned technical result is achieved by the fact that the adapter for the metering valve enables the installation of a metering nozzle on an aerosol can and comprises a coaxially arranged tube for feeding the contents of the aerosol can, an inlet element, an outlet element, and an adapter configured for connection to the metering nozzle on one side and the aerosol can on the other side. The inlet element comprises a through hole and, in communication with it, a zone for mounting the feed tube and a zone for interacting with the spray tube of the aerosol can with a stop configured to act on the spray tube of the aerosol can. The outlet element comprises a through hole and, in communication with it, a zone for mounting the feed tube. The inlet element is mounted at one end of the feed tube, and the outlet element is mounted at the other end of the feed tube.The adapter contains a through-hole for the feed tube, fastening elements on the aerosol can's atomizer ring, and fastening elements for the dispensing nozzle. The adapter is mounted on the feed tube and can be moved relative to its axis.

[0012] A metering valve for an aerosol can is designed for installation on the can and comprises a metering nozzle and an adapter. The metering nozzle comprises a housing and a push-button cap movably mounted thereon. The metering nozzle is mounted on the adapter's feed tube such that the housing of the metering nozzle is secured to the adapter by locking elements, and the push-button cap of the metering nozzle is secured to the adapter's tube by an outlet element, allowing the pressure from the push-button cap to be transmitted to the aerosol can's atomizer tube via the adapter's inlet element.

[0013] The inlet and outlet elements may contain sockets.

[0014] The feed tube may contain projections at its ends, and the inlet and outlet elements may contain corresponding recesses that ensure the fixation of the inlet and outlet elements on the feed tube.

[0015] The feed tube may comprise a thickening configured to interact with the dispensing nozzle. The push-button cap of the dispensing nozzle (5) may comprise a recess for accommodating the thickening of the tube.

[0016] The adapter's locking elements may be designed as oblique projections. The dispensing nozzle body may contain matching projections. The adapter's projections may be designed to interact with matching projections on the dispensing nozzle body to secure it in place.

[0017] The push cap of the dosing nozzle can be designed with the possibility of moving from the working position to the transport position and back.

[0020] Carrying out the invention A metering valve (6) is used in dispensers and ensures the supply of contents, such as an active ingredient, from an associated container, in particular, from an aerosol can (7). The metering valve (6) includes a metering nozzle (5) that ensures the transmission of action from the dispenser user to a means that ensures the release of contents from the container associated with the valve (6), and a transition device. The transition device is used in the design of the metering valve (6) for attaching a metering nozzle (5) of a standard design to an aerosol can (7), which is used as a container, and for transmitting action from the dispenser user to the spray tube of the aerosol can (7), which, in turn, ensures the release of contents from it, and, accordingly, ensures the operation of the dispenser.

[0021] The adapter comprises a coaxially arranged tube (3) for feeding the contents of an aerosol can (7), in particular, an ADV, an inlet element (2), an outlet element (1) and an adapter (4) configured to be connected to a dosing nozzle (5) on one side and an aerosol can (7) on the other side. The inlet element (2) is mounted at one end of the feed tube (3), and the outlet element (1) is mounted at the other end of the feed tube (3). The dosing nozzle comprises a housing (52) and a push cap (51) movably mounted thereon. The total length of the adapter (the total length of the feed tube (3) with the inlet and outlet elements (1, 2) installed, excluding the length of the adapter (4)) is selected based on the dimensions of the dosing nozzle (5)), in particular, about 89 mm, for example, 88.95 mm.

[0022] The feed tube (3) is designed to feed the contents of the aerosol can (7) through the through hole (31), as well as to fasten the remaining elements of the metering valve (6) and transmit the effect to the spray tube of the aerosol can (7). The diameter of the inner hole (31) of the tube (3) is selected to correspond to the inner diameter of the spray tube of the aerosol can (7), in particular, about 3 mm. The outer diameter of the tube (3) is selected to correspond to the elements of the metering nozzle (5), in particular, about 5 mm, for example, 4.95 mm. The length of the tube (3) is selected based on the dimensions of the metering nozzle (5), in particular, about 80 mm, for example, 80.95 mm.

[0023] The inlet element (2) is intended for connecting the feed tube (3) to the spray tube of the aerosol can (7) and for transmitting the action from the feed tube (3) to the spray tube of the aerosol can (7). The inlet element (2) comprises a through hole and a zone for installing the feed tube (3) and a zone (22) for interacting with the spray tube of the aerosol can (7) communicated with it, with a stop (23) configured to act on the spray tube of the aerosol can (7).

[0024] The outlet element (1) is fastened to the tube (3) on the outside of the push-button cap (51) and thus locks and firmly fixes the tube (3) in the metering nozzle (5) in the upper part of the metering valve (6). The outlet element (1) contains a through hole and a zone for installing the feed tube (3) communicating with it.

[0025] The outlet element (1) may have a different shape depending on the contents of the aerosol can (7) or the ADV and the various purposes of the dispenser. Specifically, an air freshener may use an outlet element (1) that directs the jet perpendicular to the tube. A urinal sanitizer may use an outlet element (1) that serves as an adapter for the tube (3) connecting to the water supply hose of the urinal flush mechanism.

[0026] According to the most preferred embodiment, the inlet and outlet elements (1, 2) are provided with bells (11, 21), preferably in the form of a funnel. The bell (21) on the inlet element (2) facilitates its installation on the spray tube of the aerosol can (7). The bell (11) on the outlet element (1) allows for the shape of the outlet element (1) to be provided, as required for the specific purpose of using the dispenser.

[0027] According to the most preferred embodiment, the feed tube (3) comprises projections (34, 36) at its ends (33, 35), and the inlet and outlet elements (1, 2) comprise corresponding recesses (12, 24) that ensure the fixation of the inlet and outlet elements (1, 2) on the feed tube (3). This design makes it possible to increase the reliability of fastening the dosing nozzle (5) on the adapter.

[0028] The adapter (4) ensures fastening of the dosing nozzle (5) on the adapter, as well as fastening of the dosing valve (6) in assembly on the ring (71) of the sprayer of the aerosol can (7). In this case, the adapter (4) comprises a through hole (43) for mounting on the feed tube (3) and is configured to be connected to the dosing nozzle (5) on one side and the aerosol can (7) on the other side due to the fact that the adapter (4) comprises elements (45) for fixing on the ring (71) of the sprayer of the aerosol can (7) on the part (42) of the adapter (4), intended for fastening to the aerosol can (7), and elements (44) for fixing the body (52) of the dosing nozzle (5) on the opposite part (42) of the adapter (4), intended for fastening the dosing nozzle (5).Moreover, the adapter (4) is installed on the supply tube (3) of the adapter with the possibility of movement relative to its axis in order to ensure the possibility of movement of the supply tube (3) when the metering valve (6) is installed on the aerosol can.

[0029] According to the most preferred embodiment, the fastening elements (44) of the adapter (4) are made in the form of oblique projections adapted to interact with the corresponding projections on the body (52) of the dosing nozzle (5) for fixing it. In this case, the body (52) of the dosing nozzle (5) is fixed to the adapter

[0030] (4) of the adapter by turning it after aligning the elements (44) securing the adapter (4) and the mating projections. This design improves the reliability of fastening the dosing nozzle (5) to the adapter.

[0031] The dispensing nozzle (5) consists of a fixed platform - a housing (52) and a push cap (51), which moves along the housing (52) under the influence of, for example, a dispenser, into which the entire cartridge (aerosol can (7) with a metering valve (6) installed) is installed. When such a cartridge is placed in the dispenser, the push cap (51) of the dispensing nozzle (5) is set in motion by the dispenser key.

[0032] The body (52) of the dosing nozzle (5) is fixed to the adapter (4) of the transition device by means of the fastening elements (44). The push cap (51) of the dosing nozzle (5) is fixed to the feed tube (3) of the transition device with the possibility of transmitting the action from the push cap (51) on the feed tube (3) and further to the spray tube of the aerosol can (7) through the inlet element (2) of the transition device.

[0033] According to the most preferred embodiment, the feed tube (3) comprises a thickening (32) configured to interact with the dosing nozzle (5). In this embodiment, the push cap (51) of the dosing nozzle

[0034] (5) contains a recess for accommodating the thickening (32) of the tube (3). This design improves the reliability of the fastening of the dosing nozzle (5) to the adapter, i.e., reduces the likelihood that the dosing nozzle (5) will fall off the adapter and the dosing valve will stop working. This design also ensures better transmission of the reverse action from the aerosol can dispenser tube (7) when the aerosol can (7) contents stop flowing.

[0035] In one embodiment, the push-button cap (51) of the dispensing nozzle (5) is movable from its working position to its transport position and back. This design prevents accidental contact with the aerosol can's spray tube (7) and preserves the contents of the aerosol can (7) during transport or installation in the dispenser.

[0036] The metering valve (6) operates as follows.

[0037] The metering valve (6) is installed on the aerosol can (7) after its assembly. Assembly of the metering valve (6) begins with the installation of the tube (3) in the corresponding hole in the push-button cap (51), then the tube (3) is fixed on the cap (51) by the release element (1), in particular, until a click is heard from the engagement of the protrusion(s) (34) on the tube (3) in the recess (12) of the release element (1).

[0038] Next, the push cap (51) is connected to the body (52) of the dosing nozzle.

[0039] (5), then the adapter (4) is inserted into the body (52) of the dosing nozzle (5), passing the tube (3) through the through hole (43), and is secured in the body (52) using the fixing elements (44) of the adapter (4). For example, in the case where the fixing elements (44) are made in the form of oblique protrusions, fastening can be carried out by turning the adapter (4) clockwise, clamping the oblique protrusions of the adapter (4) in the relief part of the body (52).

[0040] Then the inlet element (2) is fixed on the tube (3), in particular until a click is heard from the protrusion(s) (36) on the tube (3) entering the recess (24) of the inlet element (2).

[0041] The assembled metering valve (6) is installed on the aerosol can (7) by directing the inlet element (2) onto the spray tube of the aerosol can (7) and snapping the adapter (4) onto the ring (71) of the spray tube of the aerosol can (7).

[0042] The metering valve (6) is ready for use after moving the push cap (51) from the transport position to the operating position, in particular by turning it counterclockwise. When the push cap (51) is pressed, the force is transmitted through the tube (3) and the inlet element (2) to the spray tube of the aerosol can (7), after which the contents of the aerosol can (7) begin to flow out of the metering valve.

[0043] (6), passing sequentially through the inlet element (2), the tube (3) and the outlet element (1).
