DESCRIPTION:
BRIEF SUMMARY
The present invention has essentially as its subject a device for dispensing any product whatsoever contained in a container with a deformable wall.
Tubes forming a container with a deformable wall and susceptible of containing any product whatsoever such as a paste which may be dispensed through an orifice under the effect of a pressure exerted upon the wall of the tube have been on the market for some time.
But such a dispensing device exhibits the disadvantage that the pressure exerted upon the tube is a random one and it often happens that the wall of the tube is damaged and may even become punctured thereby causing leaks of product.
Furthermore containers are known which may contain any product whatsoever which may be dispensed by exerting a pressure upon a mechanical means such, as for instance, a push-button outside of the wall or the container.
But such an external mechanical means is not without its disadvantages. Such a means indeed increases the bulkiness of the container, is very often detrimental to its aesthetic appearance and above all requires the provision of a sealing system which is not always reliable. In addition such a sealing system increases the cost of the container and may promote the seizing of the mechanical means controlling the dispensing of the product.
Therefore the present invention has as its object to overcome in particular the disadvantages mentioned hereinabove by proposing a device which raises no fluid-tightness problem and which allows the deliver of any product whatsoever in an always reliable, precise manner measured in accordance with the pressure applied.
For that purpose the invention has as its subject a device for dispensing any product whatsoever contained in a container with a formable wall and forming a part of a body provided with an orifice adapted to be closed and allowing the delivery of this product, characterized by means for controlling the dispensing of the product, accommodated in the container and operable by an outer pressure exerted upon the deformable wall of this container.
It is therefore understood that the pressure exerted externally upon the deformable wall of the container will cause the delivery of the product through the medium of a control means housed inside of the container and allowing the positive and reliable delivery of a certain amount of product corresponding in a very precise manner to the pressure exerted laterally upon the wall of the container.
According to a first embodiment the aforesaid control means consists of a sector-shaped part which is pivotally mounted in the container on a support integral with the body and which co-operates with a rod actuating a valve susceptible of closing the aforesaid orifice.
The sector-shaped part pushes or pulls the rod against the force of at least one return spring.
According to another characteristic of this device the sector-shaped part is formed of two substantially parallel flanges between which is arranged one end of the aforesaid rod.
According to another embodiment the aforesaid control means is constituted by a push-button disposed inside of the container orthogonally to the axis of the body and meshing with a pinion which is made fast to this body and which itself meshes with teeth carried by a rod actuating a valve susceptible of shutting the aforesaid orifice.
According to still a further embodiment the aforesaid control means are constituted by a movable yoke or U-shaped part the base of which is substantially parallel to the wall of the container and the legs of which are recessed so as to form a ramp co-operating with the end of a rod passing between these legs and actuating a valve susceptible of closing the aforesaid orifice.
The aforesaid U-shaped part slides with its legs orthogonally to the axis of the body in a support made fast to the body.
The supports of the embodiments described hereinabove are preferably made fast to a head comprising the aforesaid orifice and valve and in which the aforesaid rod slides. The fact that the supports are made fast to the head advan
