REFILL FOR DEVICES FOR EVAPORATING VOLATILE SUBSTANCES

Abstract

A refill for devices for evaporating volatile substances includes a body (1) provided with a neck (2). The body has a first coupling means (4; 5; 6) for coupling the body to a device (10; 20; 30) for evaporating volatile substances and also at least a second coupling means (4; 5; 6) for coupling the body to a device for evaporating volatile substances (10; 20; 30).

The refill 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.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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.

[0019] FIG. 1 is a perspective view of the refill for devices for evaporating volatile substances according to the present invention;

[0020] FIG. 2 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 projection;

[0021] FIG. 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

[0022] FIG. 4 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 ring-shaped flange.

DETAILED DESCRIPTION

[0023] As shown in FIG. 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.

[0024] 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.

[0025] 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.

[0026] As can be seen in FIG. 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.

[0027] 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.

[0028] FIGS. 2 and 4 show how said coupling means are used in different evaporating devices.

[0029] FIG. 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.

[0030] In this case, the projection 4 arranged in the body 1 of the refill is snap-fitted with a tab 11 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 11, and it can be removed by carrying out the inverse movement.

[0031] FIG. 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.

[0032] 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, FIG. 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.

[0033] 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.

[0034] 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.
