Description

"DELIVERY DEVICE FOR A LIQUID OR PASTE PRODUCT"

The present invention relates to a delivery device for a liquid or paste product.

More in particular, the present invention relates to a device to be used, preferably, in the cosmetic and body care sector, for delivering liquid or paste products, such as beauty creams, oils for body treatment or massage and the like.

There are currently known, at the state of the art, different types of delivery devices for liquid or paste products, used in the aforesaid technical sector of reference.

In particular, there are known distributors for cosmetic products, to be used in the field of facial and body treatments for a person, which allow the user to collect, once or several times during the treatment, a given quantity of product required to carry out the treatment.

Normally, said known delivery devices are also provided with specific dosing means, to allow the user to collect the amount of product required for the treatment being administered, thereby reducing possible waste.

However, said known delivery devices have a plurality of problems .

Firstly, said known delivery devices are not able to provide a suitable solution to the problem related to alteration of the product to be delivered, related to the presence of microorganisms, or to different of chemical-physical causes due, for example, to the action of light, to variations in temperature, to the presence of metals or oxidation phenomena. In fact it is noted how contact of the product (for example, a cream for cosmetic treatment) with the air causes the rapid occurrence of oxidative phenomena triggered, in particular, by the action of oxygen on the lipid fraction of the compound. Evident signs of alteration of the product resulting from oxidation phenomena are, for example, a change in colour and odour thereof.

It must be noted that besides losing, completely or partly, their respective chemical-physical properties advantageous and useful for the treatment to be administered, products with these alterations can also be harmful for the health of the person receiving the treatment, causing local skin irritations or allergic reactions, in particular in the case of sensitive individuals.

Taking account of the aforesaid problems, at the state of the art, some solutions have been provided, such as the use of delivery devices that prevent exposure to light radiation (for example, through the use of tanks made of material that is opaque and preferably dark in colour) , the use of manufacturing materials that do not contain metal residues (responsible for the occurrence of oxidation phenomena of the product), storage of the delivery devices in places not exposed to specific sources of heat and/or light, when not in use.

The document US 2014/264070 Al discloses a delivery device for a liquid or paste product, comprising a container with a tank for said product, a cover for said container, said cover including a collection chamber for the product delivered following a manual operation by the user, who, upon removing the cover, uses the product thus delivered, and then re-closes the container with the same cover, wherein said device comprises:

- at least one LED light emitter means in the ultraviolet range of the spectrum, the light beam of which is emitted and directed on the inside of said chamber;

- electronic circuit means for the control and electric powering of said at lead one LED light emitter means and electric battery means connected to said electronic circuit control means;

- electronic timer means connected to said electronic circuit control means, for timing the electrical power to said at least one LED light emitter means;

control means for the electrical shut-down of said electronic circuit control means,

so that when the user re-closes said container with the cover, said control means being activated, said electronic circuit means cause electrical power to be supplied to said at least one LED light emitter means for the length of time set using said timer means, during which time the beam of light performs an anti-bacterial action on the inside and on the walls of said chamber.

However, said known solutions do not in any event provide comprehensive solutions to all the aforesaid problems.

In particular, it must be noted how any residues of product, accumulated after previous deliveries in proximity, for example, to one or more delivery nozzles or in a collection chamber of the delivered product, can lead to accumulation of bacteria .

Therefore, when the user collects a given quantity of product required for the treatment, the quantity of product, completely integral, that is delivered is particularly exposed to bacterial contamination when during delivery, respectively collection, it comes into contact with said residues of product delivered previously.

This aspect is also further emphasized by the fact that, in numerous cases, the operations to sanitize said known delivery devices are not very easy to perform and do not allow an appreciable level of cleaning and sanitization of these devices to be achieved. This inevitably leads to potential risks for the safety of the person receiving the treatment, in terms of localized skin irritations, or even infections, especially in sensitive individuals .

The use is also known, in the preparation of said products for cosmetic treatments or the like, of chemical agents that are anti-oxidant , preservative or able to provide for absorption of UV radiation.

It is nonetheless evident how the use of said chemical agents could be potentially harmful for the person receiving the treatment, besides leading to possible skin irritations, respectively allergic reactions, especially in sensitive individuals .

Therefore, it must be noted how the aforesaid problems of said known delivery devices, and in particular those related to the impossibility of appreciably reducing bacterial contamination, remain essentially unsolved.

At the state of the art it is known how light, when having a blue spectrum (range 631-668 THz - wavelength 450-475 nm) , has appreciable antibacterial properties.

In this direction, there are currently known a plurality of technical applications (for example, in the disinfection of instruments) and therapeutic applications (for example, localized skin treatments) in which light in the blue spectrum is used for bactericidal purposes.

The present invention, in consideration of the above, starting from the notion of the aforesaid problems of the cited state of the art, intends to provide a solution to these problems. An object of the present invention is to provide a delivery device for a liquid or paste product which is able to greatly reduce the risks of bacterial contamination of the product delivered, inside a collection chamber of this product. Moreover, an object of the present invention is also to provide a device as mentioned, which is able to allow the best preservation of the same product from oxidizing agents.

Another object of the present invention is to provide a delivery device as indicated, which is easy for the user to sanitize, thereby allowing an appreciable level of cleaning and sterilization to be achieved.

A further object of the present invention is to provide a device as specified, which is simple for the user to use.

On the other hand, an object of the present invention is to provide a device as said, which has a simple structure, is easy to produce on an industrial scale with essentially limited costs.

In view of these objects, the present invention provides a delivery device for a liquid or paste product, the essential feature of which constitutes the subject-matter of claim 1. Further advantageous features are described in the subsequent dependent claims.
