DESCRIPTION

The present invention relates to a refill for devices for evaporating volatile substances, which enables the assembly thereof in different types of evaporating devices.

Background of the invention

The use of devices for evaporating volatile substances such as air fresheners or insecticides is common. These evaporating devices can be connected to the electrical grid in order to cause the volatile substance to evaporate.

The volatile product that evaporates is housed in a refill coupled to the evaporating device, such that when said volatile product runs out, the refill is removed and is replaced by another refill.

The coupling of the refill with the evaporating device can be carried out in different ways, for example, by means of a thread, so that the user can easily couple and remove the refill.

A drawback of these refills is that they are specially designed for use in a single evaporating device, comprising a single coupling means to the evaporating device for which it is designed. In this way, the user is forced to remember what type of evaporating device they have in order to purchase the suitable refill for that evaporating device, since, if they buy another type of refill, they will not be able to use it with that evaporating device.

This drawback for users also has consequences for refill manufacturers, since they have to manufacture different types of refills, one for each type of evaporating device, with the subsequent manufacturing and storage costs for all these types of refills.

Therefore, an objective of the present invention is providing a refill for devices for evaporating volatile substances that enables the use thereof in more than one type of evaporating device, by providing at least two different coupling means to be able to couple to at least two different types of evaporating devices.

Description of the invention

The refill according to the present invention solves the aforementioned drawbacks and has other advantages, which are described below.

The refill for devices for evaporating volatile substances according to the present invention comprises a body provided with a neck, which comprises first coupling means to a device for evaporating volatile substances, and is characterized in that it also comprises at least second coupling means to a device for evaporating volatile substances.

Advantageously, the refill for devices for evaporating volatile substances according to the present invention also comprises third coupling means to a device for evaporating volatile substances.

According to a preferred embodiment, said first coupling means is a thread arranged in said neck of the refill, said second coupling means is a projection arranged in said body of the refill, and said third coupling means is a ring-shaped flange arranged in said neck.

Furthermore, preferably, said ring-shaped flange is arranged underneath said thread.

The refill according to the present invention has the advantage that it can be used with different devices for evaporating volatile substances by using one of said coupling means, depending on the means provided in the device.

This represents an obvious advantage for the manufacturer of the refill, as it substantially reduces manufacturing and storage costs, by manufacturing and storing a single refill that can be used with two or three different types of evaporating devices.

Brief description of the drawings

For the purpose of helping to make the foregoing description more readily understandable, it is accompanied by a set of drawings which, schematically and by way of illustration and not limitation, represent a practical embodiment.

Figure 3 is a cross-sectional view of the refill for devices for evaporating volatile substances according to the present invention mounted on an evaporating device using a thread; and

Description of a preferred embodiment

As shown in Figure 1 , the refill according to the present invention comprises a body 1 provided with a neck 2. Inside said body 1 a volatile product is housed, for example, an air freshener or insecticide product, which impregnates a wick 3 that projects from said body 1 , through which the evaporation of the volatile substances of the product occurs when the refill is coupled to an evaporating device.

According to the present invention, the refill comprises more than a one coupling means for coupling the refill to a device for evaporating volatile substances.

According to the represented embodiment, the coupling means are a projection 4 arranged in said body 1 , a ring-shaped flange 5 arranged in said neck 2 and a thread 6 arranged in said neck 2, which can be used independently from each other in order to be coupled to different evaporating devices.

As can be seen in Figure 1 , in order to enable the use of the ring- shaped flange 5 or of the thread 6 indistinctly, said ring-shaped flange 5 is arranged under the thread 6 in the neck 2 of the refill, and said ring-shaped flange 5 protruding more than said thread 6.

It should be noted that said coupling means are only examples for coupling to the most common evaporating devices. Furthermore, it is not essential that the refill have three coupling means, since it could have two of said coupling means or more than three.

Figures 2 and 4 show how said coupling means are used in different evaporating devices.

Figure 2 shows an evaporating device, generally identified by reference number 10 with the refill coupled therein, in this case by means of the projection 4 described above.

In this case, the projection 4 arranged in the body 1 of the refill is snap- fitted with a tab 1 1 of said evaporating device 10. In this way, the refill is placed by simply pushing it towards the inside of the housing thereof in the evaporating device until the projection 4 is snap-fitted inside the tab 1 1 , and it can be removed by carrying out the inverse movement.

Figure 3 shows another evaporating device, generally identified by reference number 20 with the refill coupled therein, in this case by means of the thread 6 described above.

In this case, the thread 6 of the refill is coupled in a complementary thread 21 of said evaporating device 20. The refill is placed simply by screwing it in by means of said threads 6, 21 and is removed by unscrewing it.

Figure 4 shows another evaporating device, generally identified by reference number 30 with the refill coupled therein, in this case by means of the ring-shaped flange 5 described above.

In this case, the ring-shaped flange 5 is snap-fitted with a ring 31 of the evaporating device 30. Thus, the refill is placed by simply pushing it towards the inside of the housing thereof in the evaporating device until the ring-shaped flange 5 is snap-fitted into the ring 31 , and it can be removed by carrying out the inverse movement.

Although reference has been made to a specific embodiment of the invention, it is evident for a person skilled in the art that numerous variations and modifications can be made to the refill for devices for evaporating volatile substances described above, and that all the aforementioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the attached claims.
