DESCRIPTION:
BRIEF SUMMARY
The invention relates to a cap with interchangeable dispenser, particularly suitable for being applied to containers for cosmetics, detergents and the like.
It is known that cosmetics like creams and lotions or detergents like shampoos, bath foams, cleansing agents, liquids for domestic use and the like are sold in containers that are closed by means of dispensing pumps. Said dispensers are provided with a dispensing pipe and are characterized by different shapes and dispensing diameters, depending on the product to be dispensed or to the use it is meant for.
Therefore, for example, if the product to be dispensed is creamy, like a bath foam or a lotion, the dispenser will be provided with a pipe with a circular dispensing outlet that can be large or small depending on the density of the product itself, while if the product to be dispensed is, for example, a liquid for domestic use, the dispenser will be preferably provided with a spray dispensing pipe, and so on.
Each of said caps, independently of the kind of dispenser it is provided with, is closed with a cover that generally makes up a single body with the cap itself, which is provided with a sealing element coupling with the dispensing pipe of the dispenser, thus intercepting its dispensing outlet.
It is easy to understand, therefore, that the cover of the cap must be provided with a sealing element the shape of which varies according to the shape of the dispensing pipe the dispenser is equipped with. Document DE-A-2104811 discloses a cap with a dispenser movably connected with a collar of said cap wherein the cover of said cap is provided with two sealings elements. If the shape of the dispenser changes, also the cap and the sealing elements must be changed.
Document U.S. Pat. No. 4,895,282 discloses a cap with a cover provided with a sealing elements wherein the dispenser is part of the cap and therefore can't be removed and changed with other dispenser. Therefore, the manufacturer must produce different caps according to the different profiles of the dispensing pipes with which the dispenser is provided, with the drawback of having to keep in stock considerable number of particulars in more variants.
Another drawback is represented by the fact that the manufacturer must also have a high number of molds.
It is obvious that such a high number of equipment and of articles to be kept in stock inevitably results in another inconvenience, that is, the rise in management costs.
The present invention is aimed at eliminating the above mentioned drawbacks.
In particular, the aim of the invention is the implementation of a cap suitable for being fitted with different dispensers, each one provided with a different dispensing pipe according to the needs and requirements of the customer.
The above mentioned goal is achieved through the implementation of an improved cap for containers, which, according to the main claim, comprises: container and with a substantially central through hole; central hole of said collar by means of connecting elements and provided with a dispensing pipe with dispensing outlet communicating with the inside of said container; at least two sealing elements for sealing said dispensing outlet of said dispensing pipe, characterized in that said dispenser is interchangeable and in that at least one annular sealing elements cooperates with only one corresponding profile belonging to the dispenser outlet when the dispensing pipe belonging to the dispenser is applied to said collar.
According to a practical application of the invention in question the cover of said cap has two sealing elements consisting of two rings with circular section, coaxial with each other and positioned one inside the other, which are an integral part of the body of the cover itself.
Depending on the profile of the dispensing pipe with which the dispenser is provided, when the cover is closed either of said sealing elements units couples with the corresponding dispensing pipe in order to prevent the product from flowing out of the container if this is overturned.
