Free-standing ecological multi-purpose device made of a plant polymer, preferably made of cardboard, for the progressive release of scents and fragrances into the environment

Abstract

A free-standing device for releasing fragrances includes a hollow external cylinder having an inner surface engaging the outer surface of an internal cylinder, the internal cylinder being closed. The inner surface of the external cylinder and the outer surface of the internal cylinder are fully at contact with each other. If open, the internal cylinder projects beneath the external cylinder, allowing the user to insert it into a support having a resting surface and an upper projection perforated centrally. The upper projection has aeration holes, sliding the internal cylinder with respect to the external cylinder exposing a portion of the inner surface of the external cylinder and the outer surface of the internal cylinder. A perfumed scent is applied on the inner surface of the external cylinder and/or on the outer surface of the internal cylinder; the internal cylinder having break-lines for removing portions of the internal cylinder.

Description

DESCRIPTION OF THE FIGURES

(1) The invention will be described hereinafter in at least one preferred embodiment, provided by way of non-limiting illustration, with reference to the attached figures, wherein:

(2) FIG. 1 shows a three-dimensional view of a device according to the present invention in which the external cylindrical support 1 and the internal cylindrical support 2 projecting beneath, can be seen. The break-lines 2.4, which describe, in this case, six equally spaced circumferences, highlighted by the scissors symbol, are shown thereon. The support 20 in all its components, i.e., the lower resting surface 21, the upper projection 22, the lateral holes 23 and the central hole 24 is illustrated at the lower part. In this case the upper projection 22 is provided with grooves 25.

(3) FIG. 2 shows a three-dimensional cross-section of a device showing the inner surface 1.2 provided with a plurality of reliefs 1.3 which end up engaged with the reliefs 2.3 present on the inner surface 2.1 of the internal cylindrical support 2; the circular break-lines 2.4 arranged on the internal cylindrical support 2 to allow the separate diffusion of the fragrance, are also shown.

DETAILED DESCRIPTION OF THE INVENTION

(4) Now, the present invention will be illustrated purely by way of non-limiting example, with reference to the figures illustrating some embodiments regarding the present inventive concept.

(5) With reference to FIG. 1, a fragrance diffuser consisting of the free-standing device of the present invention is shown.

(6) The external cylindrical support 1 arranged coaxially to an internal cylindrical support 2 is shown. Due to the adherence between the inner surface 1.2 of the external cylindrical support 1 and the outer surface 2.1 of the internal cylindrical support 2, these two components can reversibly take, due to the action of a user, a first closed configuration and a second open configuration.

(7) The first closed configuration is characterised in that the inner surface 1.2 of the external cylindrical support 1 and the outer surface 2.1 of the internal cylindrical support 2 are fully at contact with each other. The fact that these actually are the surfaces soaked with perfume entails that the diffusion of perfume in the environment is prevented in the first closed configuration.

(8) In the second open configuration instead, the internal cylindrical support 2, sliding axially with respect to said external cylindrical support 1, projects at the lower part. The lower projecting portion is suitable to be inserted into the central hole 24 of a support 20 suitable to confer stability to the entire device.

(9) In the second open configuration, a predetermined portion of the inner surface 1.2 of the external cylindrical support 1 and a similar portion of the outer surface 2.1 of the internal cylindrical support 2 are exposed, releasing the perfumed fragrance into the environment.

(10) Said support 20 consists of a lower flat resting surface 21 and an upper cylindrical projection 22. While the lower flat resting surface 21 is suitable to allow the stable resting of the device on a horizontal surface or if provided with an adhesive, magnet or velcro also adhesion to a vertical or inclined surface, the upper cylindrical projection 22 is suitable to be engaged with the projecting portion of the internal cylindrical support 2.

(11) Furthermore, said support 20 is provided with a plurality of lateral holes 23 suitable to facilitate the flow of air around and inside the device to increase the fragrance diffusion.

(12) In the embodiment represented in FIG. 1, said support 20 consists of a flat surface provided with a plurality of grooves 25 in proximity of the central hole 24 which allow the projecting shape of the upper part of the support 20.

(13) Furthermore, the internal cylindrical support 2 is also provided with a plurality of break-lines 2.4 suitable to allow the user to remove, in a precise and predetermined fashion, the internal cylindrical support portions 2 delimited by them. In this manner, the break-lines serve as a graduated scale for modulating the released dose of perfume preventing the open configuration from making the device too high.

(14) With reference to FIG. 2 an embodiment of the device is shown, wherein the outer surface 2.1 of the internal cylindrical support 2 and the inner surface 1.2 of the external cylindrical support 1 are provided with reliefs 1.3-2.3 consisting of thickening elements comprised between 0.5 mm and 3 mm, preferably 1 mm, suitable to increase the static sealing of the device both in said closed configuration and in said open configuration.

(15) All the components of the device are made of cardboard or any other plant polymer, thus making the device completely eco-friendly.

(16) Lastly, it is clear that the invention described up to now may be subjected to modifications, additions or variants obvious to a man skilled in the art, without departing from the scope of protection outlined by the attached claims.
