Abstract
Description
Technical Field
[0001] The present invention relates to a device for diffusing volatile substances.
Background Art
[0002] In the market, there are devices for diffusing volatile substances such as fragrance sprays that are placed in an inverted posture. Since these are products placed in an inverted posture, the problem of accurately dispensing a small amount of volatile substances is difficult to solve.
[0003] In existing products, generally, there is an intermediate wick fixed to the container using a stopper as a solution.
[0004] By placing the bottle on a base, this intermediate wick comes into contact with the secondary wick. The intermediate wick functions as a dispenser, and the secondary wick functions as an evaporation surface.
[0005] The drawback of these devices is that since the intermediate wick forms part of the fragrance container, it is not possible to ensure good contact between the intermediate wick and the secondary wick.
[0006] In addition, as another drawback, dripping may occur when operating, and furthermore, the product is generally disposable.
Summary of the Invention
Problems to be Solved by the Invention
[0007] Therefore, an object of the present invention is to provide a device for volatile substances used in an inverted posture that does not require an intermediate wick or a dosing system.
Means for Solving the Problems
[0008] The device for diffusing volatile substances according to the present invention solves the aforementioned drawbacks and also provides the other advantages described below.
[0009] A device for diffusing volatile substances according to the present invention is - A container holding a liquid containing that type of volatile substance, - A base element that closes the container, - The wick into which the aforementioned volatile substance soaks, The base element has an internal channel into which the liquid containing the volatile substance is stored, and a portion of the wick is positioned within the internal channel into which the liquid containing the volatile substance located within the internal channel permeates.
[0010] Conveniently, the base element has a window that connects the internal channel to the rest of the base element.
[0011] Furthermore, the base element includes a projection that activates an outlet valve for the liquid from the container, allowing the liquid to exit the container and flow towards the base element.
[0012] Conveniently, the base element also has a guide portion for guiding the mouth of the container, and the base element also has a plurality of evaporation holes to promote evaporation through them.
[0013] Preferably, the evaporation holes are located on the side walls of the base element.
[0014] More preferably, the wick has a projection positioned within the internal channel of the base element, the projection being located longitudinally on the wick.
[0015] According to a preferred embodiment, the wick has a cylindrical shape.
[0016] The device for diffusing volatile substances according to the present invention has at least the following advantages. - It does not require an intermediate wick or a dosing system, so it is less expensive than conventional devices. - Eliminate or minimize leakage. - Ensure correct contact between the base element and the wick and correct evaporation of the volatile substance. - Enable the replacement of the wick in a clean way.
[0017] For a better understanding of the described content, several drawings are attached, but they only represent examples of the implementation of the embodiments as schematic and non-limiting examples.
Brief Description of the Drawings
[0018] [Figure 1] Figure 1 is an exploded perspective view of a device for diffusing volatile substances according to the present invention. [Figure 2] Figure 2 is an exploded view of a longitudinal section of a device for diffusing volatile substances according to the present invention.
Modes for Carrying Out the Invention
[0019] As shown in the figure, the device for diffusing volatile substances has a container 1 containing a liquid with a volatile substance.
[0020] The container 1 has a valve 11 that is operated before using the diffusion device and a mouth 12 with an external thread, as will be described later.
[0021] The device for diffusing volatile substances also has a base element 2. This base element 2 is in an inverted position, that is, it is used to install the device with the base element 2 in the lower position as shown in the figure.
[0022] The base element 2 has an internal channel 21 into which the liquid from the container 1 enters. Therefore, the base element 2 has a protrusion 22 that actuates the valve 11 of the container 1 to open the outlet of the liquid from the container passing through the valve 11.
[0023] The base element 2 also has a guide portion 23 provided with an internal thread for guiding the mouth portion 12 of the container 1.
[0024] Furthermore, as shown in FIG. 2, the base element 2 also has a window 24 that communicates the internal channel 21 with the rest of the base element.
[0025] In order to promote evaporation, the base element 2, which is preferably cylindrical, has a plurality of evaporation holes 25, and according to the illustrated embodiment, they are arranged on the side wall of the base element 2.
[0026] The device for diffusing the volatile substance also has a wick 3 that is preferably cylindrical. The wick 3 has a protrusion 31, which is preferably positioned in the vertical direction, and at its position during use, one of its ends is placed inside the internal channel 21 of the base element 2.
[0027] Thus, according to the illustrated embodiment, the liquid with the volatile substance soaks into the wick 3 through this protrusion 31, but it is also possible to soak it in any suitable way without the need for the protrusion 31.
[0028] When it is desired to use the device for diffusing the volatile substance according to the present invention, first, the wick 3 is placed inside the base element 2 in a state where its protrusion 31 is arranged inside the internal channel 21.
[0029] Since the wick 3 is a spare element, it is replaced the required number of times.
[0030] Next, the base element 2 is attached to the container 1. At this time, the protruding portion 22 of the base element 2 is inserted into the valve 11 and the valve 11 is opened.
[0031] By positioning the diffusion device in its intended use position, that is, with the base element 2 facing downwards as shown in the figure, the liquid passes through the valve 11 and is placed in the internal channel 24, the liquid soaks into the wick 3, and the volatile substances are diffused or evaporated into the surroundings.
[0032] In the illustrated embodiment, the diffusion or evaporation occurs through the evaporation holes 25, but it can also occur through the gap between the base element 2 and the container 1.
[0033] Notwithstanding the fact that references have been made to specific embodiments of the present invention, it will be obvious to those skilled in the art that, without departing from the scope of protection defined by the accompanying claims, the above-described devices for diffusing volatile substances are susceptible to many modifications and alterations, and that all of the detailed descriptions provided can be substituted by other technical equivalents.
