Apparatus for heating and moisturising shaving cream

Abstract: There is disclosed an apparatus for heating and moisturising shaving cream dispensed from a valve (1a) adjacent the top of a pressurised container (13) and comprising a fluid vessel (11) for holding a hot fluid e.g. hot water having a specific gravity greater than that of the shaving cream to be dispensed and having a vertical dimension approximating the vertical dimension of the pressurised container (13), with the vessel (11) being disposed laterally adjacent and vertically coextensive with the pressurised container (13); and a conduit (8) for depositing shaving cream dispensed from the valve (1a) into the hot fluid within the fluid vessel (11) near the bottom of the vessel (11), so that the shaving cream can move upwardly through the hot fluid via its own buoyancy so as to be heated and moisturised, and then made available for use via a discharge spout (5).

Description: This invention relates to apparatus for heating and moisturising shaving cream dispensed from a valve adjacent the top of a pressurised container of shaving cream. It is known to provide shaving cream in pressurised containers, but there are a number of performance faults associated with current shaving products, in the form of foams and gels. Although these shaving products provide lubrication and prevent drying, they do not contribute heat and extra moisture to the shaving area. When these products are released from their pressurised containers, the release of pressure and expansion of the product causes cooling. In addition, it is not economical, in the case of foam, or feasible, in the case of gel, to include enough water in the pressurised product container to provide a generous level of actual moisture. US 3300095 discloses a mixing head mounted on the top of a pressurised primary fluid container and having a housing containing a secondary fluid such as hot water for blending with the primary fluid discharge from a valve in the primary fluid container. The housing includes a slotted tube generally concentric with the wall of the housing and aligned with the discharge valve of the pressurised container such that the primary fluid passing through the discharge valve passes upwardly within the tube. The tube is defined by a plurality of circumferentially spaced legs, and slots between the legs enable the shaving cream to be moisturised by the secondary fluid as it passes upwardly through the tube. GB 1095887 discloses means for heating the contents for pressurised aerosol container comprising a unit attachable to the top of an aerosol dispenser such that contents from the aerosol container passing through a valve thereof pass through a circuitous or tortuous conduit in a container of hot water such that heat exchange between the aerosol contents and the hot water can occur. The apparatus of the invention seeks to overcome this problem by providing supplemental conditioning of shaving cream dispensed from a pressurised container, by way of heating and moisturising of the products prior to use. Accordingly, the invention provides apparatus for heating and moisturising shaving cream dispensed from a valve adjacent to the top of a pressurised container, the apparatus comprising: (a) a fluid vessel for holding a hot fluid having a specific gravity greater than that of the shaving cream to be dispensed; and (b) conduit means for depositing shaving cream dispensed from the valve into said hot fluid within said fluid vessel near a lower extremity of said vessel, when said vessel is disposed laterally adjacent to pressurised container; characterised in that said vessel has a vertical dimension approximating a vertical dimension of the pressurised container, said vessel to be disposed in a position laterally adjacent, and vertically coextensive with, the pressurised container and no containment or obstruction to moisturisation of the shaving cream occurs as the shaving cream passes through the hot fluid. Preferably, the conduit means comprises a delivery tube extending from the valve adjacent the top of the pressurised container, through a wall of said vessel, and to a position adjacent a lower extremity of said vessel. The delivery tube may comprise a duct extending only laterally and downwardly from the valve of the pressurised container, wherein the flow of shaving cream is facilitated. Preferably, the vessel has a tapered top portion for accumulating shaving cream after upward passage through a column of hot fluid in the vessel. Preferably, the top portion of the vessel has a discharge spout and is shaped so as to direct accumulated product towards an inlet of the spout. Accordingly, in apparatus according to the invention, conditioning of a dispensed shaving cream can be achieved by directly contacting these products with a hot fluid e.g. hot water to produce hot, moist shaving products, which improve the shaving process compared to conventional methods of product use. The apparatus of the invention therefore provides a product conditioning unit capable of causing a pressurised product, such as shaving foam or gel, to be conditioned by being heated and moisturised by direct contact with hot fluid. Further, the apparatus can be made to conform with i.e. to receive pressurised product containers in current or future use. One embodiment of apparatus according to the invention will now be described in detail, by way of example only, with reference to the accompanying drawing, in which: Figure 1 is a side view of apparatus for heating and moisturising shaving cream and adapted to receive a pressurised container of such shaving cream; and, Figure 2 is an end view of the apparatus shown in Figure 1. Referring now to the drawing, there will be described, by way of example only, an apparatus for heating and moisturising shaving cream dispensed from a valve adjacent to the top of a pressurised container of the shaving cream. The apparatus comprises a fluid vessel 11 for holding a hot fluid, usually hot water, having a specific gravity greater than that of the shaving cream to be dispensed, with the vessel 11 having a vertical dimension approximating a vertical dimension of a pressurised container 13 which the apparatus is adapted to mount therein. As can be seen in Figure 1, vessel 11 is disposed in a position laterally adjacent to, and vertically coextensive with the pressurised container 13. Conduit means is provided for depositing shaving cream dispensed from the container 13, and comprises a delivery tube 8 which has a top arm extending substantially horizontally away from an inlet pressure connector 1 to a pressure valve 1a at the top of the pressure container 13, and then extends downwardly through a seal 2 and within vessel 11 towards the bottom thereof, and then is inturned to form a tube outlet 3 a small distance above the base of the vessel 11. Therefore, when vessel 11 is located laterally adjacent to the pressurised container 13, and upon depression of inlet pressure connector 1, shaving product is dispensed under pressure out of the pressurised container 13 along delivery tube 8 to emerge from outlet 3 near the bottom of the column of hot water within the vessel 11. The apparatus of the invention may comprise a holder adapted to receive any design of pressurised container 13, and also incorporating vessel 11 to be located alongside pressurised container 13, and coupled therewith, as an integral structure. Alternatively, the apparatus of the invention may comprise an attachment incorporating vessel 11, delivery tube 8 and pressure connector 1, and which can be coupled with a pressurised container to form a unit therewith. Reference 14 indicates one form of means for coupling together the pressurised container 13 to the vessel 14. Returning now to description of the vessel 11, this will normally be filled with hot water up to level 4, which is just below a top closable portion of the vessel formed by a spout body 6 having a spout inlet 6a, and a spout outlet 5. A water inlet 7 allows the vessel 11 to be filled with hot water, and a cap / seal 9 having hinge 10 can close the water inlet 7. As indicated above, delivery tube 8 enters the vessel 11 via a seal 2 at a location at which tube 8 enters, affixes to and seals to the vessel 11. Reference 12 indicates generally the upper tapered accumulator above the water level 4 in which dispensed shaving products can collect after upward passage through the hot water in the vessel 11. The operation of the apparatus consists initially of filling the vessel 11 with hot water through inlet 7 up to water level 4. The cap 9 is then closed to cover and seal the water inlet 7. Next, following application of downward force on inlet pressure connector 1, pressure valve 1a releases product from the pressurised container 13. After the product passes through the pressure valve 1a, it enters inlet pressure connector 1 under pressure. This then directs flow of pressurised product into delivery tube 8 to which inlet pressure connector 1 is attached. Delivery tube 8 directs a flow of pressurised product to the lower interior region of the vessel 11 and issues from the delivery tube outlet 3. The delivery tube enters, affixes and seals itself to the vessel 11 at the delivery tube entry point formed by seal 2. After issuing from delivery tube outlet 3, the product is released into the hot water contained in the vessel 11. Since the specific gravity of the hot water is greater than that of the shaving cream, the shaving cream rises through the column of hot water by its own buoyancy and, during this passage through the water, it acquires both heat and moisture by direct contact with the water. Upon rising above water level 4, hot and moist i.e. conditioned product is then accumulated within accumulator top 12 and is directed to spout inlet 6a by means of the tapered upper end shape of the accumulator 12. Conditioned product enters spout 6 at inlet 6a and then exists at spout outlet 5. Conditioned product is therefore now ready for use. After use, water is dumped out of the vessel via the inlet 7, and the entire apparatus then can be rinsed out to store until next use.
