Benefits of technology

[0017] This makes it possible to increase the rate of the air coming into the container and thus to accelerate the recovery of its initial shape by the container.
[0018] Passages are preferably distributed uniformly around the feeder tube end, in order to facilitate a uniform distribution of the air coming into the container and thus make it possible for the container to recover its initial shape.

Problems solved by technology

But such devices have the following disadvantages:
When the bottle loses its shape because of a manual pressure on its side wall, the upper part of the bottle (which is located close to its opening) also loses its shape and the bottle hardly recovers its original shape;

Embodiment Construction

[0033] Within the scope of the exemplary embodiment of the device according to the invention shown in FIGS. 1 to 9, the device is intended for the packaging of liquid cosmetic or pharmaceutical products.

[0034] As can be seen in FIGS. 1 and 2, more particularly, the device includes a container 1 made of a shape memory elastically deformable material.

[0035] The container can thus be deformed when its side wall is compressed and it can elastically return to its initial shape.

[0036] Said liquid to be delivered is stored in container 1. The liquid is introduced into the container through an opening 10 (FIG. 5).

[0037] The container 1 includes at least two communicating chambers 11 and 12, connected together by two deformable zones 13 and 14 (FIG. 6) which allow to press the chambers close to one another by pressing on their outer wall, a channel 15 being provided between the two chambers 11 and 12 and forming a passage for the liquid contained in the container 1.

[0038] Both deformabl...

Abstract

The invention concerns a device for packaging and delivering a liquid product, comprising a container deformable by pressure applied on its side walls, wherein said liquid to be delivered is stored, said container being closed by a head for dispensing the liquid product which is traversed by an outlet for the liquid product. The device also comprises a liquid drawing tube whereof one end is fixed proximate the outlet for the liquid, the tube being of such length that its other end is proximate the base of the container. The wall of the container comprises cavities partly delimiting the outline of the dispensing head. The invention is characterized in that at least one passage is provided proximate the dispensing head to ensure an air intake into the container after the liquid is dispensed, so as to allow the container to recover its initial shape by replacing by volume the dose of liquid delivered.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application is a continuation of pending International patent application PCT / FR2005 / 003302 filed on Dec. 29, 2005 which designates the United States and claims priority from French patent application 0502998 filed on Mar. 25, 2005, the content of which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to a device for packaging and dispensing a liquid contained in a container. BACKGROUND OF THE INVENTION [0003] It more particularly, but not exclusively, concerns a bottle intended to contain a cosmetic or pharmaceutical product, having such a viscosity that the product can be delivered by pressing the bottle walls, and more particularly by compressing the bottle walls. [0004] Such liquid product dispensers are known, which comprise a bottle made of a material resilient enough to be able to recover its original shape after a deformation. [0005] The bottle has an opening through whi...
