Description

[0018] The subject of the invention is shown in an embodiment in the figures, in which FIG. 1 presents a dispensing device as the cover of an external supply container in a side perspective view,

[0019] FIG. 2 presents a longitudinal section of the dispensing device,

[0020] FIG. 3 presents a lower body of the dispensing device in a side perspective view,

[0021] FIG. 4 presents the lower body of the dispensing device in a section along a vertical axis,

[0022] FIG. 5 presents a side view of an upper body of the dispensing device and

[0023] FIG. 6 shows a cross-section of the upper body of the dispensing device along the line AA from FIG. 5.

[0024] As shown in the embodiment in FIG. 1, a dispensing device 100 for dispensing liquids and semi-liquids e.g. cosmetics including perfumes, lotions, creams, emulsions and also medicinal substances, can be a cover 18 of a larger supply container 19, that can form a source of a liquid or semi-liquid substance e.g. perfumes for the dispensing device 100, when the dispensing device 100 is emptied. As shown in FIGS. 1 and 2, the dispensing device 100 is an irregularly shaped spatial body, but it is obvious that it can have a shape of a regular solid, for example a cylinder, a cube or any other cuboid. The cover 18 may have a shape and dimensions known from common perfume bottle covers.

[0025] The dispensing device 100 is suitable to put therein a smaller amount of substance, e.g. several single doses, said dispensing device 100 being equipped with its own pumping mechanism 5, allowing use of the dispensing device 100 to dispense the liquid or semi-liquid substance it contains, such as perfume or cologne.

[0026] As shown in FIG. 2, in the embodiment, the dispensing device 100 comprises a housing 1, in which an upper body 2 and a lower body 3 are located. A deformable reservoir 4 is located around the lower body 3 and a pumping mechanism 5 is located in the upper body 2. The lower body 3 is also shown in FIG. 3 in a perspective view and in FIG. 4 in an axial section. The upper body 2 is also shown in FIG. 5 in a side perspective view and in FIG. 6 in a section according to the line A-A from FIG. 5.

[0027] The reservoir 4 of the dispensing device 100 is a deformable diaphragm 4a of a ring shape, enclosing the lower body 3 and being attached to it by elastic rings 10 on both of its edges, as shown in FIG. 2, FIG. 3 and FIG. 4. Obviously, in other embodiments the reservoir 4 can have a different shape, such as a shape of a deformable bag, attached to the lower body 3 on one side by the elastic ring 10 and on the other side sealed to an upper surface of the lower body 3 by pressing it with internal elements of the housing 1.

[0028] As shown in FIG. 2 and FIG. 4, a supply valve 6 is located in the lower body 3, depicted in FIG. 4, wherein the supply valve 6 is connected by means of a lower channel 7, shown in FIG. 2, to the reservoir 4, and wherein a dispensing valve 8, visible in FIG. 2, is connected by an upper channel 8 and a side channel 9 with the pumping mechanism 5. In this embodiment, the supply valve 6 is a ball valve, closeable by a compression spring 20. In addition, the compression spring 20 is supported by pressure inside the reservoir 4. It is also possible that the supply valve 6 will only be closed by pressure inside the reservoir 4. In this embodiment the dispensing valve 8 is a ball valve, closeable by an upper spring 11. It is obvious that in a rest state a force of the upper spring 11 of the dispensing valve 8 is greater than a force resulting from the pressure in the reservoir 4, so that the dispensing valve 8 remains closed despite an increase in pressure in the reservoir 4, resulting form pumping liquid into it and stretching the wall of the diaphragm 4a of the reservoir 4.

[0029] The lower channel 7, connected to the supply valve 6, exits the lower body 3 into the inner surface of the reservoir 4, between the elastic rings 10.

[0030] After filling the reservoir 4 and disconnecting the dispensing device 100 from a source of substance, the dispensing device 100 can be used to dispense the substance contained therein, which in the embodiment is perfume. The dispensing device 100 is a container of a travel type and contains a much smaller amount of substance than can be contained in a typical home perfume container, for example a bottle.

[0031] In order to allow for dispensing of a substance, such as perfume, from the dispensing device 100, it is provided with the pumping mechanism 5, as shown in the embodiment in FIG. 2, FIG. 5 and FIG. 6. The pumping mechanism 5 is a button 12, supported by a return spring 13, wherein the button 12 is connected to a piston 14, the piston 14 being located in a first chamber 15, said first chamber being provided in the upper body 2 of the dispensing device 100. The first chamber 15 of the dispensing device 100 is connected by the upper channel 9 to the dispensing valve 8 in the upper body 2.

[0032] In the upper body 2, behind the first chamber 15, there is a second chamber 16 located, connected to an atomizer 17. Between the first chamber 15 and the second chamber 16 a membrane plug 21 is located, the membrane plug 21 being supported by an additional spring 22, wherein the membrane plug 21 is for controlling of a flow of the substance to channels 23, connecting the second chamber 16 to the atomizer 17.

[0033] When the user of the dispensing device 100 presses the button 12, the piston 14 compresses the substance contained in the first chamber 15, between the piston 14 and the second chamber 16. The dispensing valve 8 prevents the substance from entering the reservoir 4. The pressure in the first chamber 15, caused by the pressure exerted on the button 12 causes the membrane plug 21, pushed towards the first chamber 15 through the additional spring 22, to be pushed towards the outlet of the atomizer 17. This movement of the membrane plug 21 exposes the channels 23, connecting the first chamber 15 to the atomizer 17, and results in dispensing the liquid substance, in this embodiment—a perfume, in a form of an aerosol mist.

[0034] Releasing the pressure on the button 12 activates the return spring 13, which pulls the piston 14 in the first chamber 15 towards the button 12. This action, in a first aspect, releases the membrane plug 21, which, moving under the action of the additional spring 22 towards the first chamber 15, closes the channels 23 and, in a second aspect, under the influence of the vacuum created, it opens the dispensing valve 8. The substance, which in this embodiment is perfume, passes from the reservoir 4 through the dispensing valve 8 into the first chamber 15 and the dispensing device 100 is ready to dispense another portion of substance. This can be done by pressing the button 12 again. Of course, this will only be possible until the reservoir 4 of the dispensing device 100 is completely empty.

[0035] To refill the reservoir 4, the dispensing device 100 must be connected to a source of substance to be dispensed. Such a source may be, for example, a larger container with a liquid or semi-fluid substance, for example perfumes. To this end, the dispensing device 100 and the larger container can be suitably adapted to a dedicated filling of the dispensing device 100 by ensuring their interconnection and coupling of a path of the liquid substance.

[0036] It is also possible to fill the dispensing device 100 from any container, equipped with a pressure pump or containing a liquid or semi-fluid substance under pressure by removing a typical spray tip from the container, for example with perfumes, and pressing the pump tip of that container onto the supply valve 6 of the dispensing device 100.
