Abstract
Description
Technical Field
[0001] The present invention relates to a perfume bottle or a bottle containing a hydroalcoholic composition incorporating a sprayer outlet directed upward at a specific angle with respect to the longitudinal axis of the bottle and an adjustment mechanism capable of supplying the spray at a partial rate. It is applicable to both individual bottles and a set of bottles arranged opposite or in a circular shape to obtain a specific mixture of perfume for the user or for an empty bottle to be refilled. It comprises a bottle arranged on a base so as to be electromechanically actuated through the base, which can be manually actuated or can form a system.
[0002] It can be particularly applied in the field of the perfume industry, especially to perfume bottles equipped with a sprayer and automatic dispensing devices.
Background Art
[0003] There is a common method, called "layering", practiced by both perfume manufacturers and users, which consists of mixing commercially available perfumes to create a personalized scent. One way to perform layering consists of the manufacturer creating and marketing scents or essences intended to be mixed together. Another way consists of mixing several perfumes from different ranges, which may or may not be from the same manufacturer, to create a new scent. The latter is more user-driven, either to create a mixture of products for sale proposed by the manufacturer or for the purpose of personalizing a unique perfume or making it less expensive by mixing several perfumes of different prices.
[0004] The manufacturer's proposal for layering perfumes involves having two or more perfumes and achieving the desired mixture by completely spraying them onto a part of the body. This technique is very limited because it is limited to a mixture, which is the only unit of measurement that can be taken in a single spray. An exemplary embodiment using three perfumes is described below. - One spray of perfume 1 + one spray of perfume 2 + one spray of perfume 3 results in perfumes with proportions of 33.33% / 33.33% / 33.33% respectively, for a total of 3 sprays. - Two sprays of perfume 1 + one spray of perfume 2 + one spray of perfume 3 result in perfumes with proportions of 50% / 25% / 25% respectively, for a total of four sprays. - Three sprays of perfume 1 + one spray of perfume 2 + one spray of perfume 3 result in perfumes with proportions of 60% / 20% / 20% respectively, for a total of five sprays.
[0005] As you can see, to lower the proportion of one perfume, the proportions of others must be increased considerably. This means that more products are used, and the amount of perfume used creates a point where the mixture becomes unsustainable. Therefore, instead of spraying the perfume onto the part of the body to which it is applied, it is applied in the form of a stream.
[0006] Document EP3880259A1 comprises a device that incorporates a casing and a rotatable carousel as a revolver for housing several cartridges having perfume arranged sequentially, such that a specific amount of perfume is drawn out from the inside by an actuator and deposited into a bottle positioned below. Since this receiving bottle is a conventional bottle from which the atomizer has been removed, it is filled with different perfumes in desired proportions.
[0007] The cartridge used is described in document EP3849622, and consists of a perfume bottle with the conventional elements of a commercially available bottle, except for the missing atomizer, but in its place there is a tube that pushes the liquid perfume downwards, and everything is surrounded by a casing.
[0008] This invention has the disadvantage that the cartridge used cannot be used directly as a single perfume bottle and cannot be freed from the aforementioned device, and furthermore, that a spray sample of the mixture cannot be available, and rather the bottle must be refilled in order to know the result of a particular mixture. Unlike the proposed device, this device can be included in a machine for making perfume in a laboratory, which has a clear advantage for the user.
[0009] Document WO2021061056 discloses an electronically controlled perfume dispensing device that performs spraying by a mechanism located inside a casing. The device includes several bottles so that the user can select a preferred mixture in a personalized manner.
[0010] The techniques used primarily involve transferring fluids using components specific to the purpose, such as pumps, solenoid valves, and check valves, and compressing a mixture of liquids within the same atomizer.
[0011] This invention has the disadvantage that, because it uses a unified fluid system, when preparing a mixture, if the first perfume is used, all common fixed elements of the apparatus become impregnated with it. When the next bottle is used to draw the product from the next bottle, all elements are already contaminated with the previous product. As a result, an undesirable mixture is obtained due to contamination from the perfume before it substantially alters the mixture. [Overview of the project] [Problems that the invention aims to solve]
[0012] Those skilled in the art know that perfume compositions, in addition to substances that provide the characteristic fragrance of the perfume itself, also include fixed elements or substances, which are intended to ensure the adhesion and persistence of the perfume on the part to which it is applied and to contaminate any part or element over which the perfume flows, particularly irremovable elements such as those described in the relevant patent.
[0013] This invention solves these problems that have not been overcome in the current state of the art and presents a perfume bottle that can be used to apply small amounts to the user, and multiple perfume bottles can also be used in a device for applying specific combinations. [Means for solving the problem]
[0014] This invention refers to a perfume bottle having a series of differentiating features compared to bottles already commercially available.
[0015] The bottle consists of a head containing a spray nozzle from which the perfume to be sprayed comes out, a container as a housing in which the perfume is placed, and a body surrounding the container through which the head slides to perform spraying. It should be noted that the container, together with the head, incorporates all elements known in the prior art to enable spraying simply by pressing the head.
[0016] A first feature of the bottle of the present invention is that the spray nozzle is tilted upward at a specific angle with respect to the longitudinal axis of the bottle, preferably between 40 and 50 degrees. At this angle, spraying is performed so that the perfume is dispensed slightly upward, instead of being dispensed horizontally at 90 degrees with respect to the longitudinal axis of the bottle, as is known in the prior art.
[0017] The second feature of the bottle is the incorporation of an adjustment mechanism that allows the spray to be supplied in partial proportions. For example, adjustments can be made to values that are easy for the user to understand, such as 25%, 50%, 75%, or 100% of the spray. To achieve this adjustment, the bottle head incorporates markings indicating the amount of spray to be supplied. The head is attached to the bottle body by a ramp mechanism, or alternatively, a toothed mechanism, which allows the spray to be performed only partially, according to a predetermined amount, rather than completely. Thus, by rotating the head, the mechanism is positioned in the selected location.
[0018] The present invention also relates to a perfume bottle, particularly its housing, which can incorporate two operating elements, and for that purpose has two operating elements, a push button and an actuator.
[0019] The first activator is a push button located on the head of the bottle, which is intended to be activated by the user in a conventional manner by simply pressing it, causing the liquid to come out of the spray nozzle, as is the case with any known perfume bottle. This activator is incorporated into the bottle described.
[0020] The second activation component is an actuator intended to use the bottle as an electromechanical device. It consists of an operating projection located at the bottom of the bottle and connected to an internal mechanism. This actuator is intended to be used in combination with an electrically operated base that pushes the projection to produce a spray.
[0021] When an electric base is used, the adjustment mechanism for releasing partial spray is electronic and acts directly on the motor, specifically adjusting its stroke.
[0022] When the base motor applies an impact to the protruding part of the bottle, the bottle tends to move in the direction of the impact it receives. To avoid this movement of the bottle and to prevent the impact from being applied exclusively to the actuator, on the one hand, the bottle incorporates a recess in the surrounding lower zone, and on the other hand, the base incorporates a retaining mechanism that, when a driving force is applied, fixes a tab into the recess of the bottle, preventing its movement.
[0023] This holding mechanism can consist of a manually operated tab positioned on the base, which, when the bottle is placed in the base, is actuated by pressure to settle into a recess, thus holding the bottle against movement that transmits the force of an actuator causing the perfume to spray. However, the holding mechanism can also be electromechanical, as will be discussed later.
[0024] Furthermore, the base may be intended to accommodate a single bottle or multiple bottles.
[0025] With this actuator, the present invention becomes an electromechanical device equipped with all electronic elements known and not described in the art such as a power supply device, a motor, an MCU, sensors, Wi-Fi connection or Bluetooth, etc., and the spraying of perfume can be carried out via an application by an electric device such as a mobile phone, a computer or the like.
[0026] The adjustment and actuation mechanisms are individual for each perfume bottle and it is possible to make combinations between the perfume bottles in different ratios. To achieve this, it is sufficient to operate the mechanisms of several bottles simultaneously at a specific ratio and direct it directly towards a point intended to receive the mixture.
[0027] By combining all of the above, the present invention enables three embodiments as described below.
[0028] The first embodiment consists of an individual perfume bottle with the particularity of allowing adjustment of the desired spraying ratio directly on the bottle itself, as is applied directly to the user's skin as in a commercial bottle. Its application is, as always, by pressing the head to spray.
[0029] The second embodiment consists of an electromechanical application of the atomizer, and for this reason, the present invention is configured as a system incorporating an electric base that actuates the protrusion arranged on the bottle. This embodiment focuses on a single bottle or several bottles used together. This last case is more general and incorporates the case of a single bottle and is what will be described.
[0030] In this system, the bottles are arranged in a circle on a base, and all atomizers are directed towards a projection point in space where the user preferably places them on their wrist or a desired part of their body. The user adjusts the spray ratio of each perfume bottle not by physical but rather by an electronic adjustment mechanism, unlike manually adjusted bottles. The adjustment of the spray ratio is preferably performed through an application intended for this purpose, which sends commands to each motor, each motor responsible for acting on the actuator of the corresponding bottle and spraying the mixture in a synchronous manner. However, it can also be performed by a physical selector programmed to act on the motors. This technology allows for the application of perfumes in a wide range and precise proportions using various perfumes, as the adjustment is electromechanical and the spray can be adjusted in intervals of 1% or less.
[0031] Given the possibility of adjusting the bottles, this technique allows for countless combinations by using several bottles. Extrapolating to the example above, as mentioned earlier, it becomes possible to avoid the perfume coming out onto the user's body in the form of a stream and to create a mixture using a much smaller amount of perfume. With specific adjustments to the standard spray, the example above is modified as shown below. - One spray of perfume 1 (adjusted 25%) + one spray of perfume 2 (adjusted 25%) + one spray of perfume 3 (adjusted 25%) yields perfumes with proportions of 33.33% / 33.33% / 33.33%, which is 0.75 sprays in total compared to the conventional method of 3 sprays. - One spray of perfume 1 (adjusted to 50%) + one spray of perfume 2 (adjusted to 25%) + one spray of perfume 3 (adjusted to 25%) results in perfumes with proportions of 50% / 25% / 25% respectively, resulting in a total of 1 spray compared to the conventional method which requires 4 sprays. - One spray of perfume 1 (adjusted to 75%) + one spray of perfume 2 (adjusted to 25%) + one spray of perfume 3 (adjusted to 25%) yields perfumes with proportions of 60% / 20% / 20% respectively, resulting in a total of 1.25 sprays compared to the conventional method which requires 5 sprays.
[0032] A third embodiment of the invention involves incorporating a perfume refill bottle. In this case, as in the previous one, the perfume bottles are arranged in a circle on a base, but the bottles are intended to be refilled in a gap located in the center of the base. This is achieved by adjusting the motor speed so that the spray velocity of all the bottles falls to a point where it becomes a flow. The refill bottle is filled by a component fixed to the bottle and located in the center, such as a funnel with a central hole, which collects all the perfume supplied so that it is directed toward an empty bottle located below the hole in the funnel. The funnel is configured with embossments around its circumference to connect different bottles and may also incorporate a shield intended to be located in front of the outlet of the perfume bottle's spray nozzle to prevent the supplied perfume from falling outside the funnel in the case of an oversized spray.
[0033] Because perfumes contain a high proportion of highly volatile alcohols, it is important to emphasize the motor adjustment techniques applied to the actuator so that the perfume is released in liquid form rather than as a spray. Otherwise, this substance, which is crucial for the preservation and consistency of the perfume, will be lost.
[0034] Thus, in summary, the present invention relates to a perfume bottle having a head, a spray nozzle positioned in the head, a container housing a mechanism for spraying perfume and a supply conduit to the spray nozzle, and a pump, and a body having a longitudinal axis in which the container and the head are housed together.
[0035] The spray nozzle is tilted with respect to the longitudinal axis of the bottle body and is equipped with an adjustment mechanism that determines the spray ratio. The tilt is between 40 and 50 degrees, and the adjustment mechanism provides multiple spray ratios depending on its location at different positions.
[0036] The adjustment mechanism can be a ramp mechanism that allows for continuous adjustment of the supplied spray ratio, or a toothed mechanism that allows for adjustment of various supplied spray ratios.
[0037] Furthermore, the present invention also relates to a perfume spraying system in which the described type of bottle is used.
[0038] However, for the use of bottles in this system, the bottle has protrusions and recesses that contact the container, respectively, for lifting movement to perform spraying and for holding the bottle in place during this lifting movement.
[0039] This system has a base with a bottle holder, which has an actuator fixed to the base and associated with the bottle holder. It also has a motor for applying spray.
[0040] The spraying system also features multiple bottle holders on the base, with actuators associated with each of the holders.
[0041] A single motor can be used to operate the system with multiple bottles, but it is preferable to use a motor for each actuator, thereby allowing for independent and direct adjustment of the partial spray for each bottle without the need for additional mechanisms.
[0042] The motor used for spraying, whether used with a base with a single bottle or a base with several bottles, can have its stroke adjusted, thereby causing the piston to advance more or less depending on the spray ratio the user wants to apply.
[0043] Furthermore, the user can adjust the motor speed, choosing between a high speed for applying spray and a low speed where the spray comes out in the form of a flow.
[0044] The use of a motor at low speed to apply perfume in a flow requires a spraying system that also incorporates a collector having a central gap in the base to accommodate the refill bottle, and a funnel shape with a central hole, intended to be fixed to the bottle, thereby aligning the hole with the central hole. In this way, by selecting a spray with a predetermined proportion, each bottle fires a flow of perfume, which falls into the collector, ends at the central hole, and goes to the refill bottle placed below. This operation is repeated as many times as necessary until the refill bottle is filled with the desired amount.
[0045] Regarding the configuration of the actuator, on the one hand, the lift mechanism may have a gear, a rack that meshes with the gear, a piston integrated with the rack, and a guide having through slots for controlling the holding mechanism. On the other hand, the holding mechanism may have a pair of tabs, each having a pair of legs connected by a pin housed in a slot, through which the pin can move. [Brief explanation of the drawing]
[0046] To complete this specification and to help make the features of the invention more easily understandable, this specification is accompanied by a set of drawings which constitute an essential part of this specification, and which are shown below, as examples and not limiting.
[0047] [Figure 1] Figure 1 shows a longitudinal cross-sectional view of the bottle of the present invention in a non-operating or dormant position. [Figure 2] Figure 2 shows a perspective view of the base with the bottle lift mechanism and its components.

[Figure 4] Figure 4 shows a perspective view of the bottle of the present invention positioned on a base in the operating position. [Figure 5]Figure 5 shows a perspective view of a base with a lift mechanism for lifting the bottle and its components in a non-operating position. [Figure 6] Figure 6 shows a perspective view of a base equipped with a lift mechanism for lifting the bottle and its components in the operating position. [Figure 7] Figure 7 shows a bottle with the head separated from the body to illustrate the toothed attachment mechanism for creating a partial spray. [Figure 8] Figure 8 shows different positions of the head relative to the bottle body based on the desired spray ratio, and a diagram of a lamp mechanism as an alternative to the toothed mechanism. [Figure 9] Figure 9 shows the base with five bottles before they are placed on the base for electromechanical operation. [Figure 10] Figure 10 shows the base of Figure 9 with the bottle already assembled and the collection element assembled to the bottle for filling the refill bottle, which is positioned in a hole in the center of the base. [Modes for carrying out the invention]
[0048] The present invention relates to a perfume bottle that incorporates a sprayer outlet directed upward at a specific angle with respect to the longitudinal axis of the perfume bottle, and an adjustment mechanism that allows for partial spraying either manually or electromechanically by an electric base (19), in which case it can also be applied to several bottles simultaneously.
[0049] Figure 1 shows the bottle of the present invention, and it can be seen that the bottle consists of a head (1), a container (3) containing perfume and a dispensing mechanism, a spray nozzle (2) from which the perfume is released to the outside, and a main body (4) that surrounds the container (3) and houses the head (1).
[0050] Figure 2 shows the actuator responsible for performing the spray electromechanically. To this end, the actuator incorporates a holding mechanism (7) and a lifting mechanism (8).
[0051] The lift mechanism (8) includes a gear (9), a rack (10), a piston (11), and a guide (12).
[0052] Gear (9), although not shown in the drawing, is actuated by the motor shaft.
[0053] The rack (10) meshes with the gear (9), has side walls, and ends at the base.
[0054] The piston (11) is mounted on the base of the rack (10), which has a longitudinal axis in the direction of movement of the rack (10).
[0055] Each of the guides (12) incorporates a through slot (13) having a meandering shape.
[0056] The retaining mechanism (7) has a pair of tabs (16), each tab having a pair of legs (14) connected by pins (15) housed in their respective slots (13), the pins (15) being movable through the slots.
[0057] The actuator moves when it has a bottle to house it, as shown below.
[0058] The actuator starts from a resting position where the holding mechanism (7) is in a lower position. When the motor is activated, the gear (9) starts to rotate, moving the rack (10).
[0059] This causes, on the one hand, the piston (11) to be lifted and push the protrusion (6) of the bottle to spray.
[0060] On the other hand, this causes the guide (12) to lift, moving the pin (15) from the outermost position at the top of the slot (13), as seen in Figure 5, to the innermost position at the bottom of the slot (13), as seen in Figure 6. Figures 5 and 6 represent the bottle positioned in the actuator and are shown in cross-section to see how the movement of the holding mechanism (7) is caused to go from the non-operating position to the operating position, respectively.
[0061] Due to this movement, the tab (16) moves from its extended position to a more closed position and is housed in a recess (5) incorporated into the body (4) of the bottle, preventing it from being moved by the force exerted by the piston (11).
[0062] Figures 3 and 4 show bottles housed in actuators in a non-operating or idle position and an operating position when spray supply is initiated, respectively.
[0063] As mentioned above, one object of the present invention is that the bottle can release a partial spray instead of the conventional full spray, which can result in a large amount of product, particularly when the application of perfume by several bottles is required.
[0064] Manual partial spraying can be performed by an adjustment mechanism located between the head (1) and the bottle body (4). In this sense, the head (1) incorporates markings that define the desired spray ratio, and by rotating it, the head (1) is positioned relative to the bottle body (4) to release the desired spray. Depending on the position of these two elements, their movement is more or less restricted, resulting in smaller or larger sprays, respectively.
[0065] Figure 7 shows the bottle of the present invention, and the head (1) of the body (4) is shown in an exploded view so that the adjustment mechanism responsible for spraying on a percentage basis can be seen. This figure shows that the adjustment mechanism consists of a toothed mechanism (18) formed by two elements connected to each other, namely a first element (18a) located in the head (1) in the lower zone and a second element (18b) located in the body (4) in the upper zone.
[0066] Figure 8 shows the different positions the adjustment mechanism can take for the use of the toothed mechanism (18), and the different positions the first element (18a) can take relative to the second element (18b). It also shows a ramp mechanism (17) formed by a support (17a) and a ramp (17b), which has the same principle as the toothed mechanism (18), but provides continuous position adjustment rather than discontinuous and jerky adjustment.
[0067] In this sense, Figure 8 represents a planar simulation of the positions of the two elements of the adjustment mechanism in the two shown embodiments. It can be seen how the two elements (18a, 18b) of the toothed mechanism (18) are not in contact in the resting position, and only come into contact when sprays are performed in proportions of 25%, 50%, 75%, and 100% of the spray, causing the body (4) to move more or less relative to the head (1), and how the two parts of the adjustment mechanism come into contact at specific positions that apply larger or smaller sprays, respectively. Similarly, the ramp mechanism (17) is in a resting position where the support (17a) and the ramp (17b) are not in contact.
[0068] Figure 9 shows a base (19) with multiple housings (24) intended to accommodate perfume bottles for performing layering or simultaneous release of several perfumes to obtain different results. Each of the bottle housings (24) is associated with an actuator, and the base (19) can incorporate a motor for the operation of each actuator, or for the operation of several actuators, or a single motor for the operation of all actuators. However, not incorporating a motor for each actuator avoids the problem of synchronization between sprays from different bottles, but it has the further problem that a further adjustment mechanism must be incorporated into each actuator so that the motor movement operates differently on each actuator, operating more or less depending on the selected spray ratio.
[0069] Figure 10 shows the base (19) of Figure 9 with the bottle already placed in the housing (24), and includes a refill bottle (21) housed in a central gap (20) defined in the base (19), and a collector (22) fixed to the bottle below the spray nozzle (2).
[0070] This configuration is for embodiments where the spray speed is very low, and instead of creating a spray, the bottle releases a liquid stream through the spray nozzle (2), which falls onto the collector (22) and reaches the refill bottle (21) through the central hole (23). Therefore, the motor speed must be adjustable by the user. To this end, the system may incorporate a push button that the user can access to select between a spray position and a flow position. Alternatively, the push button may be electronically controlled so that the position is selected from an electronic application in a control device such as a mobile phone, computer, tablet, or the like.
[0071] The collector may incorporate an unexposed screen, intended to cause the liquid to collide with the screen and fall back into the collector (22) instead of exiting the collector (22) if the release of the liquid perfume is stronger than expected.
[0072] Finally, it should be considered that the present invention should not be limited by the embodiments described herein. Other configurations can be implemented by those skilled in the art based on this specification. Accordingly, the scope of the present invention is defined by the following claims.
