Problems solved by technology

[0019] As a result, the dip tube has a relatively complex structure and its assembly is difficult to reconcile with high production rates
[0020] Furthermore, a cover made of metallic material that comes into contact with the product may cause undesired interactions with said product, in particular physicochemical changes with the product, for example, the cover may cause said product to assume a different color

Embodiment Construction

[0087] figure 1 A product storage and dispensing container 1 provided with a pump 2 according to the invention is shown schematically and in perspective.

[0088] exist figure 1 In the position shown, the assembly has the entire axis X-X' shown in a position assumed to be vertical.

[0089] In the example embodiment shown, the container 1 comprises a reservoir having a closed bottom end 3 and an open top end 4 forming a neck on which the pump 2 is mounted, eg by swiveling.

[0090] For example, containers are used to contain cosmetic products or care products. Cosmetic products are to be understood as products as defined by Commission Directive 93 / 35EC of 14 June 1993.

[0091] However, if any other fluid, liquid or viscous product is contained in the container 1 or dispensed by the pump 2, it does not constitute a departure from the scope of the present invention.

[0092] from figure 1 As can be seen, the pump 2 consists essentially of a dip tube 5 comprising a lower en...

Abstract

A pump is arranged to be mounted on a product storage and dispensing container (1). The pump includes a variable-volume pumping chamber and a dip tube (5) having a first end (6) able to be inserted inside the container where it picks up product and a product-dispensing second end (8) at the exit from the pumping chamber. The dip tube can be produced by extrusion and typically has two valves (10, 11) and at least one elastically deformable portion running between the valves.

Description

technical field [0001] The present invention relates to a dispensing pump for mounting on a product storage and dispensing container for dispensing a product stored therein. [0002] More specifically, the present invention relates to a pump for dispensing a product by deforming a variable volume suction chamber, for example by hand or with an actuator. Background technique [0003] Such pumps, for example, are already known in the prior art. Thus, document EP-B-0900598 discloses a pump for fluid cosmetic products, said pump comprising a suction chamber elastically deformable under the action of a button and associated with an inlet valve for the product, said valve being mounted on The reservoir of the pump communicates and is coupled with a product dispensing valve that delivers product as it exits the pump. [0004] According to the pump described in this document, the button is actuated in all directions coaxial with the container, thus imposing severe restrictions on ...
