SCENT SWITCH DEVICE

TECHNICAL FIELD

The present invention relates to a device, preferably a device suitable for sanitary or air refreshing purposes, comprising an inner portion, which further comprises at least two compartments, each containing at least one different substance to provide a changing fragrance experience based on the targeted release of the substances in the at least two compartments of the inner portion based on the configuration of the device and based on the configuration the position of the compartment within the device.

BACKGROUND

Sanitary and air deodorant devices for a variety of environments are relevant tools used in private and public rooms. The main purpose of said devices is to scavenge malodors and/or to positively influence the mood of a subject as mediated by a fragrance component comprised within the device.

One example for a sanitary device is a rim block. Typical rim blocks usually have to fulfill, disinfecting, cleaning and deodorizing purposes, and are composed of solid mass, gels or combinations of the same and a device for holding and fixing the active ingredient.

Currently rim blocks are available in a variety of cages which can deliver exclusively one fragrance with or without a cleaning agent. The disadvantage of this type of rim block is that consumers can experience only one fragrance all the time. The human and the animal brain and thus their perception has the tendency to shut the smell receptors after a few breaths and initial recognition of a fragrance, i.e., to get adapted to a fragrance experience, or to get used to said experience due to molecular mechanisms based on the relevant receptors. Therefore, within only a few breaths, the intensity of a smell provided fades and a subject or consumer cannot enjoy the fragrance over a longer period of time.

Furthermore, typical rim blocks swell inside their holders, when getting in contact with the flush water. Thus, the typical rim blocks lose their shape and are dissipated unevenly. Further, the holders are usually completely filled with flush water getting in contact with the rim block inside, which leads to an excessive dissipation of the rim block and thus potentially to an unpleasant consumer experience.

Within the last years, aesthetics and performance were of increasing importance and gelatinous or liquid rim blocks, possibly in rim blocks with several chambers, have been developed. However, still in the current rim blocks with several chambers, all chambers are having contact with water and the substances of all chambers are released simultaneously with every use. Still, only one fragrance, or substance, or mixture of substances, will be released by the device and will be experienced by the consumer and the consumer will always have the experience of the same substances when using such devices, which may lead to a possible nose blindness of the consumer. Further, with e.g., dual phase rim blocks, one phase tends to dissolve faster than the other phase, leading to a disparity in the dosing of the ingredients in the final flushes of the toilet as all rim block chambers are always equally accessible to flush water.

There is thus a great need in defining new rim block forms, to overcome scent related limitations by using a second generation device. Furthermore, specially designed fragrances can provide enhanced consumer experience, which may be suitable for a variety of further consumer product areas, in particular as a scent or fragrance component may be individually combined, e.g. with a suitable cleaning agent to achieve a dual fragrance, cleaning and/or disinfecting effect.

Moreover, new rim block forms may overcome an uneven and/or excessive dissipation of the rim block, by providing a targeted dissipation.

The object of the present invention was therefore to provide a device which releases changing substances to maintain the consumer's pleasure in the substance experience for a long period of time and in a targeted way to provide a varying fragrance experience over time.

DETAILED DESCRIPTION

The present invention thus provides a variety of different configurations for devices suitable for scent switch applications.

According to a first aspect of the present invention, there is provided a device (1) comprising an inner portion (2) attached to a suspension (3) and one or more rotation control devices (4) and optionally an outer portion (5), wherein the inner portion (2) comprises at least two compartments, each containing one or more substance(s) and being separated from each other by walls, and wherein the inner (2) and/or the optional outer (5) portion comprises at least one notch (6) configured to assure that only one defined compartment of the inner portion (2) at a time gets in contact with water and/or air, and wherein the, one, two or more or all rotation control device(s) (4) enable(s) rotation of the inner (2) and/or the optional outer (5) portion to assure that the rotation of the inner (2) and/or the optional outer (5) portion is stopped and/or activated to guarantee a targeted contact of water and/or air with one defined compartment of the inner portion (2).

The device according to the invention thus provides a facilitated use to the consumer. The consumer is provided with a multiple substance containing device, thus allowing him to apply a plurality of substances in a targeted and controlled way, with only one device.

Furthermore, the device according to the invention improves the consumer's perception of the substances contained in such device. As the inner (2) and/or the optional outer (5) portion of the device (1) rotate and only one defined compartment of the inner portion (2) may get in contact with water and/or air, the substances released from the device (1) are differing. Therefore, the consumer's adaptation to a fragrance or to an experience of a substance contained in the device (1) is reduced.

In one embodiment according to the present invention, the shape of the inner (2) and optional outer (5) portion may be cylindrical, spherical, cubic, pyramidal, cuneiform or wedge-shaped, in spinner form, or in the form of a thin sheet. Usually, the shape of the inner (2) and optional outer (5) portion will be adapted to the environment where the device is used. For air refreshing devices being used in a detached form, there will thus be fewer limitations than for installed or attachable devices, e.g., for rim blocks or devices being used as filter cartridges in a car for providing a scent switch device.

In one embodiment of the present invention, the at least two compartments of the inner portion (2) are separated from each other by walls, wherein the walls can be made of any material suitable for preventing a diffusion of any of the substance(s) from one compartment to the other, or for preventing any other mixture of the substances of different compartments. If the device comprises an outer portion (5), the sides of the compartments of the inner portion (2) facing the outer portion (5) and/or the notch (6) may also be uncovered, partially uncovered and/or may also have a notch (6) as described above.

In one embodiment of the present invention, the suspension (3) is constructed in a way that the inner (2) and/or optional outer (5) portion are attached to the suspension (3) but can rotate along the axis of the suspension (3).

In a further embodiment according to the present invention, the at least one notch (6) is configured in a shape, a size, and if more than one, a distribution, that guarantees that only one compartment at a time is covered by the at least one notch (6). The rotation control device(s) (4) further position the inner (2) and/or the optional outer (5) portion in a way, that only one compartment of the inner portion (2) is covered by the one or all notch(es) (6) at a given time.

In one embodiment according to the present invention, the compartments of the inner portion (2) may further be subdivided in sub-compartments, which contain one or more substance(s) that may differ from those of other sub-compartments. All aspects of the present invention that apply for a compartment also apply for a compartment being subdivided.

Water and/or air of the environment surrounding the device (1) is/are intended to flow through the device (1). Optionally, the rotation of the inner (2) and/or the optional outer (5) portion may be thereby driven by the flow of water and/or air.

In yet a further embodiment of the present invention, the, one, two or more or all rotation control device(s) (4) may stop and/or activate the rotation of the inner (2) and/or the optional outer (5) portion.

For stopping the rotation, the, one, two or more or all rotation control device(s) (4) may comprise a stop mechanism (4a), which ensures a stop of the rotation in determined positions, thereby positioning the inner (2) and/or optional outer (5) portion in a way that only one defined compartment of the inner portion (2) at a time gets in contact with water and/or air. Such stop mechanisms (4a) may be selected from the group of spatial barriers, magnetic stoppers, wooden, plastic or metal disks, hatches, rings, weight controlled mechanisms, a position detecting mechanism, gravitational mechanisms, rotating mechanism, or flaps. For activating the rotation, the, one, two or more or all rotation control device(s) (4) may possess a structure for activating rotation, such as propellers, paddles, wooden, plastic or metal disks, hatches, rings, weight controlled mechanisms, a position detecting mechanism, gravitational mechanisms, rotating mechanism or electric mechanisms, which can be propelled by the water and/or air of the surrounding environment, by an electric motor, by the air pressure in the surrounding environment, manually, gravitation or a piezo crystal, or any combination thereof.

In one embodiment, the activating mechanism can comprise at least one sensor, for example a sensor for light, movement or a person sitting down on the toilet, or the activating mechanism can comprise a timer for activating the rotation of the inner (2) and/or optional outer (5) portion.

Furthermore, water and/or air is/are intended to interact with the at least one substance of the respective compartment of the inner portion (2) by establishing a targeted contact with the at least one substance.

A targeted contact of water and/or air with one defined compartment of the inner portion (2) comprises a contact of water and/or air with the substance(s) contained within the respective compartment of the inner portion (2). Such a contact can be made possible by the at least one notch (6) of the inner (2) and/or the optional outer (5) portion.

A targeted contact further comprises the contact of water and/or air with only one of the compartments of the inner portion (2), and the substance(s) within, at a time. Such a contact can be temporally limited. The temporally limited contact has the advantage that less material is consumed as there is exclusively one interacting compartment at a time. This results in a decreased consumption of the at least one substance in the at least two compartments and thus results in a more ecological and sustainable device, at the same time having the changing user experience over time. Therefore, the device according to the present invention is configured as multifunctional device which may have individually and/or synergistically acting components with different effects such as a perfuming, anti-malodour, cleaning, foam forming, chalk protection, antibacterial, disinfecting, oxidating or complexing effect. Thus, the device has the advantages of being user friendly as it can be refilled manually and with individually selected substances. Furthermore, the device combines additional economic advantages, as less waste is produced than with single used devices. These economic factors are combined with a greatly enhanced physical comfort on the side of the consumer.

A notch (6) in the outer portion (5) may enable water and/or air from outside the outer portion (5) entering the outer portion (5) and getting in physical contact with the substance(s) contained within the respective compartment of the inner portion (2).

A notch (6) in the inner portion (2) may provide the release of the substance(s) contained within the respective compartment of the inner portion (2) from the respective compartment of the inner portion (2) and thus enables physical contact of water and/or air with the respective substance(s). Further, a notch (6) in the inner portion (2) may enable water and/or air from outside the inner (2) and/or optional outer portion (5) entering the inner portion (2) and getting in physical contact with the substance(s) contained within the respective compartment of the inner portion (2).

A targeted contact of water and/or air with the substance(s) contained within the respective compartment of the inner portion (2) is meant to comprise the uptake of a portion of the respective substance(s) into water and/or air, resulting in a solution, dispersion or mixture of substance(s) with water and/or air. Such a solution, dispersion or mixture is meant to leave or be released from the device (1) so that the at least one ingredient, preferably at least one fragrance, comprised can be released and thus be perceived by the consumer.

A device according to the invention thus has further advantages by providing a targeted contact of water and/or air with the substance(s) contained within the respective compartment of the inner portion (2). Due to the configuration of the compartments of the inner portion (2), only the outer surface of the substance may be in contact and interact with the water and/or air. The dissipation of the substance within the compartment is much lower, compared with typical devices of the state of the art, where the whole substance is washed round. Thus, an excessive dissipation is avoided and a device according to the invention is thus more sustainable and economical than typical devices of the state of the art.

For free-standing devices, in particular air refreshing devices, to be placed in closed rooms, within devices, such as an oven, a cupboard or a fridge, or within devices used in open areas, or within an air refreshing device for use in a transportation vehicle, for example, a car, train, or aircraft, the rotation control device (4) and the notch (6) can be optional. Furthermore, in certain embodiments the rotation of the inner (2) and/or outer (5) portion to each other may not be necessary for allowing controlled access to the at least two compartments.

In one embodiment of the invention, the, one, two or more of the substance(s) of at least one of the compartments may be in a solid, liquid, or gas state, in a manner independent of any other of the substances. The state of the substance may largely depend on the usage environment of the device and the purpose of the device.

The term liquid is meant to be understood as a state of a substance in which a flux of the substance is possible. Such a state comprises the further conditions low, medium and highly viscous, paste-like and the like.

The term solid is meant to be understood as a state of a substance in which a flux of the substance is not possible and the term further comprises the state semisolid, gelatinous and the like.

According to the various aspects of the present invention, the, one, two or more of the substance(s) of at least one of the compartments may comprise at least one ingredient independently selected from the group consisting of

- a. a fragrance and/or
- b. a substance with anti-malodour activity and/or

The substance(s), leaving or being released from the device (1) as solution, dispersion or mixture with water and/or air, can advantageously fulfil specific functions especially desirable in the sanitary field such as providing good smell, being a support in cleaning and prevention of chalk and a combination of those. The functions are preferably fulfilled outside the device.

Any combination or mixture of the aforementioned substances can be perceived according to the present invention. A combination or mixture according to the invention will largely depend on the usage environment, i.e., the place, where the device is placed and thus used, and the usage purpose, i.e., sanitary purposes, air refreshing purposes and the like.

As the inner (2) and/or the optional outer (5) portion of the device (1) according to the present invention rotates and only one compartment of the inner portion (2) may be in contact with water and/or air, different substances can be released from the device (1). Therefore, functional substances that are not mandatory in each use of the device but may be required to be released e.g. only every second or third use, can be applied to the surrounding environment in an appropriate way. This is particularly suitable for expensive substances, where a controllable and economical release is desired, or for substances, for example harsh cleaning agents, which could destroy the surrounding environment, or which could cause bleaching if the respective substance is continuously released.

According to the various aspects of the present invention, the device (1) may comprise an outer portion (5), wherein the notch (6) is at least one window in the wall of the outer portion (5), which has a size not bigger than one compartment of the inner portion (2), and wherein the outer portion (5) may have one or more opening(s) (7).

Windows in the wall of the outer portion (5) are to be understood as gaps or other openings in the wall of the outer portion (5). Such openings enable the contact between the substance(s) of the compartments of the inner portion (2), which they are covering, and the environment outside the outer portion (5), which may comprise water and/or air and preferably collects a portion of the substance(s) of the inner portion (2) during contact, as described above.

The term at least one window, which has a size not bigger than one compartment, comprises one or more windows, wherein the area of the wall of the outer portion (5), which is covered by the one or more windows and on which the one or more windows are distributed over the wall of the outer portion (5), is not bigger than the surface of one compartment facing the outer portion. Moreover, the area of the wall of the outer portion (5), which is covered by the one or more window(s) and on which the one or more window(s) is/are distributed over the wall of the outer portion (5) has a shape and size equal to one compartment of the inner portion (2). Furthermore, the one or all window(s) is/are positioned on such a defined area. Thereby it is ensured that not more than one compartment of the inner portion (2) at a time gets in contact with water and/or air through such window(s).

If water enters the outer portion (5), it is advantageous if the outer portion (5) comprises one or more opening(s) (7), so that the water will not remain inside the outer portion (5), but can get out through the opening(s). By enabling the water to be removed from inside the outer portion (5), the risk of inside remaining water having contact with compartments of the inner portion (2) other than desired or inside remaining water serving as ground for fungi, bacteria or the like is reduced. Furthermore, undue interaction between water and a substance in a given compartment can be reduced so that the consumption of the at least one substance can be kept low in an economic way.

In an embodiment, comprising an outer portion (5), the, one, two or more or all rotation control device(s) (4) may assure that only one compartment of the inner portion (2) is covered by the notch (6), and the one or more substance(s) of any one of the at least two compartments may be solid.

In an embodiment, not comprising an outer portion (5), the notch (6) may be at least one window in the wall of any one of the at least two compartments of the inner portion (2), the inner portion (2) may comprise at least one closing flap (8) for each window, and the one or more substance(s) of the at least two compartments may be in a gas form or liquid.

The at least one closing flap (8) may be opened and closed due to gravitational force: The closing flap (8) of the compartment at the bottom of the device (1) is pulled down by gravitational force and uncovers its window, whereas the closing flap of the compartment at the top of the device (1) is pushed down by gravitational force and covers its window (FIG. 2). As a result of rotation of the inner (2) and/or the optional outer (5) portion, the open and close state of the respective compartments is changed.

If the substance(s) of the compartment of the inner portion (2) comprise(s) a liquid, the notch (6) may comprise further constrictions, valves, or the like to ensure a controlled release of the liquid, e.g. a viscous liquid, a gel, or a suspension.

If the substance(s) of the compartment of the inner portion (2) comprise(s) a gas, the open and close mechanism may not be controlled only by gravity but by a mechanical and/or magnetic and/or electric mechanism ensuring a defined temporal limitation of the opening time of the notch (6).

In one embodiment, the at least one substance within one of the compartment of the inner portion (2) may be provided in a capsule form.

As an alternative of or addition to gravitational force controlling the opening time of the at least one window, the device (1) may comprise a mechanical and/or magnetic and/or electric mechanism and/or a clock regulating the opening times of the at least one window in determined time intervals.

According to the various aspects of the present invention, the, one, two or more or all rotation control device(s) (4) may be independently selected from the group consisting of a disc, a rotor, a valve, a mechanical stopper, a flap, a hatch, an angular controller, a ring, a joint, a socket, a lock and key model or any combination thereof.

According to the various aspects of the present invention, the, one, two or more or all rotation control device(s) (4) may be configured to stop the rotation of the inner (2) and/or optional outer (5) portion at a position where only one defined compartment of the inner portion (2) at a time gets in contact with water and/or air, and said defined compartment may be a different one as the compartment before the rotation.

In an embodiment of the invention, comprising an outer portion (5), the outer portion (5) may comprise one or more opening(s) (7), wherein the one or more opening(s) (7) may be fine pores.

The use of fine pores as one or more opening(s) (7) in the outer portion (5) is an advantage as the fine pores facilitate the removal of water from inside the outer portion (5) and simultaneously provide adequate protection of the compartments of the inner portion (2) not being positioned at the notch(es) (6) and optionally not covered at this side.

According to the various aspects of the present invention, the one or more rotation control device(s) (4) may be positioned

- a. proximal to the inner portion (2), and/or

The expressions “proximal to” and “distal to” the inner portion (2) are referred to the figures in an alignment such that the reference numbers and the notations of the figures can be read in normal orientation. “Proximal to” equals “left of” and “distal to” equals “right of”, referring to the figures. In the figures:

Preferred embodiments and further aspects of the present invention emerge from the attached patent claims, the figures and the following examples, the examples not being intended to limit the scope of the present invention.

EXAMPLES
Example 1

To provide a prototypic device for use in toilet purposes, the three dimension printing device “Ultimaker 2” was used. The device as shown in FIG. 1 was constructed using polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) as material. Other plastic/polymer materials were used to achieve a prototypic device having varying flexibility to test, which parts of the device have to be more rigid or more flexible. The various experiments aimed at providing a device which has low production costs, a high flexibility to be placed in a variety of different toilet bowls, and still a certain stiffness to allow the positioning of varying compartments inside the device. Further tests with different cleaning and fragrance compositions were done. For example, one rim block in a reusable configuration, and a one-way use rim block were printed. Notably, the material for reusable configurations should resist to certain mechanical movements so that the inner portion with the at least two or several different containers or compartments can be easily removed and replaced without damaging the device or the holder. For configurations of the device using a mechanical stopper (also used in a rotation control device as shown in FIG. 4) it turned out to be suitable to use a stiffer material for those parts being under higher mechanical stress to guarantee a certain longevity of the device and a proper movement mechanism.

Example 2

Furthermore, it was tested whether scent switch devices could be used as air refreshing tools. A device was constructed, comprising three compartments. The change of the active compartment was initiated by a timer and performed by an electric motor. The stop mechanism of the rotation control device was a position detecting mechanism. Compartment 1 was filled with the fragrance geranial, compartment 2 was filled with the fragrance patchouli oil and compartment 3 was filled with floralozone, having anti-malodour activity. The device provided the changing substances to the surrounding environment and the fragrances and substances with anti-malodour activity were experienced for a longer time than with typical devices.
