Description

The invention relates to devices for aromatizing air in rooms and confined spaces, for example, in a car interior.

The prior art design of an air freshener (see, for example, patent US4157787 for the invention of "Air freshener dispenser", IPC A61L 9/04, publ. 06/12/1979), which includes a container made of plastic filled with liquid or gel flavoring, one of the walls of which is a multilayer film, wherein the inner layer of said film is made of vapor-permeable flavor material, and the outer layer is detachably connected to the inner layer and made of material impermeable to the flavor. Before using the freshener, the top layer is removed, ensuring the release of flavor vapor from the container through the pores in the lower layer of the film into the atmosphere surrounding the freshener.

The liquid or gel flavor used in modern air fresheners is a mixture of several substances with different properties.

The disadvantage of the known fresheners is as follows. During long-term storage, the substances that make up the flavor are stratified.

After removing the top layer of the multilayer film from the freshener tank, the most “volatile” substances are evaporated first, as a result of which the aroma is distorted, and the substances remaining in the fragrance lose “volatile properties”.

The service life of such a freshener is very limited, since the remaining substances, comprising up to half the initial mass of the flavor, do not evaporate and remain unused.

The prototype of the claimed utility model is an air freshener design known from US Pat. No. 6,725,278 B2 for the invention “Apparatus for dispensing volatile materials”, IPC A24F 25/00, A61L 9/04, publ. 04/20/2004

The design of the prototype includes a plastic container with a flat flange filled with liquid or gel-like flavoring, one of the walls of which is a multilayer film attached to the flange, the inner layer of the said multilayer film is made of vapor-permeable flavor material, and the outer, detachable layer said multilayer film is made of a material impervious to flavor.

The technical result of the claimed utility model is the creation of an air freshener, characterized by an extended service life and a constant aroma throughout the entire service life.

The specified technical result is achieved in the design of an air freshener, including a container with a liquid or gel-like flavoring, bounded by the walls, at least one of the walls of which is a multilayer film, the inner layer of the said film made of vapor-permeable flavoring material, and the outer detachable the layer of said film is made of a material impervious to flavor.

The technical result is achieved by the fact that the air freshener is equipped with a ball placed inside the container with the ability to move and designed to mix the substances that make up the flavor, and the inner layer of the multilayer film is made of low density polyethylene (LDPE, low density polyethylene) with a thickness of at least 40 microns .

The container in one embodiment can be made in the form of a soft bag, at least one of the walls of which is a multilayer film, the inner layer of the aforementioned film is made of vapor-permeable flavoring material, and the outer detachable layer of the aforementioned film is made of impermeable for flavoring material ..

The container in another embodiment can be made in the form of a container with a flange adjacent to the multilayer film, the inner layer of the film made of vapor-permeable flavor material, and the outer detachable layer of the film made of impermeable material for the flavor.

As a multilayer film can be used a multilayer film comprising the following layers:

- polyethylene terephthalate reinforced with aluminum foil (outer detachable layer);

- low density polyethylene (inner layer).

The utility model is illustrated by illustrations.

In FIG. 1, 2 show some examples of the implementation of the design of the air freshener.

The positions in the figures indicated:

1 - package;

2 - liquid or gel flavor;

3 - the inner layer of the multilayer film;

4 - ball for mixing the substances that make up the flavor;

5 - container;

6 - a flange;

7 - the inner layer of the multilayer film;

8 - the outer layer of the multilayer film;

9 - ball for mixing the substances that make up the flavor.

The designs described below explain the essence of the claimed technical solution, but do not exhaust the options for its implementation.

The utility model can be implemented in the design of an air freshener, see Figure 1, which includes a container in the form of a bag 1, limited by the walls, in which a liquid or gel-like flavoring is placed 2. At least one of the walls 3 of the bag is a multilayer film the inner layer of which is made of vapor-permeable flavoring material, and the outer detachable layer is of a material impervious to flavoring.

To implement the utility model, a ball 4 is placed in the container, and the inner layer of the multilayer film is made of low density polyethylene with a thickness of at least 40 microns.

The thickness of the inner layer of the multilayer film (40 microns) was selected experimentally, based on its strength when used in the design of the ball freshener 4.

Ball 4 in a preferred embodiment of the utility model is made of a polymeric material. The ball may be made of other materials, for example, glass or metal.

It should be noted that if the air freshener container is in the form of a package, the two walls can be a multilayer film, the inner layer of which is made of vapor-permeable flavor material, and the outer detachable layer is made of material impermeable to the flavor.

The utility model can be successfully implemented in the design of an air freshener, see Figure 2, which includes a container in the form of a container of arbitrary shape 5 with a flat flange 6, in which a liquid or gel-like flavor is placed (not shown in Figure 2). A multilayer film is adjacent to flange b, the inner layer 7 of the film is made of vapor-permeable flavor material, and the outer layer 8 of the film is made of impermeable material for the flavor.

To implement a utility model, a ball 9 is placed in a container 5; the inner layer 7 of the multilayer film is made of low density polyethylene with a thickness of at least 40 microns.

Ball 9 in a preferred embodiment of the utility model is made of a polymeric material. The ball may be made of other materials, for example, glass or metal.

Air freshener is used as follows.

After storage, shake the freshener before first use. When shaking the ball, placed in the tank of the freshener, moves inside the tank and mixes the substances that make up the flavor, making the composition of the flavor uniform.

It is advisable not to remove the outer layer of the multilayer film before first use before shaking the ball; shaking can be more intense.

Then the outer layer of the multilayer film is removed, making it possible for the molecules of volatile substances that make up the fragrance to pass through the pores of the inner layer of the multilayer film into the surrounding air space.

The air surrounding the freshener has a pleasant smell.

It should be noted that when using an air freshener in the car interior, mixing of the substances that make up the fragrance with a ball often occurs - whenever the car moves on rough roads.

In the case of using an air freshener in a stationary room, the user is able to independently shake the freshener capacity with the ball inside it, providing effective mixing of the substances that make up the flavor.

New consumer properties of the proposed air freshener, consisting in almost doubled the service life of the air freshener and unchanged during the entire service life of the aroma, have been experimentally verified using an air freshener in the passenger compartment.
