Definitions

• Two-component type fluid dispensing device Two-component type fluid dispensing device.
• the present invention relates to a device for dispensing a fluid product of the two-component type, that is to say for dispensing two different products.
• different products is meant either products having a different composition, or different concentrations of the same product.
• the object of the present invention is to avoid the aforementioned drawbacks.
• the present invention aims to provide a single device for dispensing fluid products for dispensing two different products in the same dispenser.
• the present invention also aims to provide such a dispenser of fluid products making it possible to obtain the most effective treatment possible at the lowest possible cost.
• Another object of the present invention is to provide such a device for dispensing a fluid product which avoids the risk of confusion between the two products to be dispensed, thereby improving safety for the user.
• the present invention therefore has for its object and a device for dispensing fluid products, comprising a dispensing member, such as a pump, mounted on a container, and an actuating member, such as a pusher, for dispensing product.
• the device comprising two reservoirs of products arranged so that they are emptied successively, the product contained in the second reservoir being dispensed only when the first reservoir is empty, the first reservoir being fixed to the body of the distribution or to a support part of said body, and extends to the bottom of the container at least partially inside the second tank.
• the first reservoir is connected to the dispensing member and the second reservoir is connected to said first reservoir by means of a closure element which prevents the passage of the product contained in the second reservoir towards the dispensing as long as the first tank contains product and which frees said passage when said first tank is empty, so that subsequent actuations of the device distribute the product contained in the second tank.
• said first reservoir is made in one piece with the body of the dispensing member or with the support piece of said body.
• the first reservoir 10 is connected directly on one side to the dispensing member 1, that is to say to the pump, and comprises on the other side a connecting channel 15 which extends up to 'near the bottom of the container 2, where it is connected to the second tank 20 which is formed directly in the container 2.
• the first tank 10 is made in one piece with the pump body and / or with a support piece 9 of the pump body, as shown in FIGS. 1 to 3.
• This support piece 9 receives the pump body in its interior and rests on the neck of the container, but it is also possible to remove this piece support 9 and placing the pump body directly on the neck of the container.
• the seal between the pump body and the support piece 9 is achieved by radial clamping while in the embodiment shown in Figure 3, the seal between the support piece 9 and the pump body is made by means of an advantageously O-ring 8.
