Benefits of technology

The invention prevents foreign body pollution of the substances contained inside the receptacle, and in the event of prolonged use of one only of the substances, stagnation of the other substance in the dispensing channel is avoided. This reduces the risk of the dispensing channel clogging or of the substance spoiling on contact with air.
In a particular embodiment of the invention, the rotary dispensing head can take up an angular position in which it closes the device, said channel then being isolated from said openings. Since the device is opened or closed by rotating the dispensing head without separating the parts of the device, problems associated with losing the top or with foreign bodies such as sand penetrating and then making closure difficult, as are encountered with prior art tubes and bottles, are avoided.

Problems solved by technology

Such a device does not provide entire satisfaction, in particular because foreign bodies such as sand or dust can penetrate into the receptacle when it sucks in air as it returns to its initial shape after dispensing substance.
In addition, after prolonged use of one only of the substances, the other substance contained in the associated dispensing channel can dry out or spoil in contact with air.

first embodiment

FIG. 1 shows a packaging and dispensing device 1 constituting the invention. The device 1 comprises a receptacle 2 having two compartments 3 and 4 designed to receive two lotions for providing protection against exposure to the sun, and having different protection factors. The receptacle 2 is made using any conventional technique for shaping plastics material, e.g. by injection blowing or by extrusion and heat sealing. The compartments 3 and 4 are separated by a partition 5 and they open out to the top end of the receptacle 2 via respective openings 6 and 7 having parallel axes and of circular cross-section.

On the outside, the receptacle 2 has a shoulder to define a setback 8 for securing a cover 9. The cover covers the openings 6 and 7 and the zone where the partition 5 connects to the region of the top wall of the receptacle that extends between the openings. The setback 8 is radially defined on the inside by a tubular wall 10 on the outside of which there is formed an annular gro...

second embodiment

FIG. 2 shows a packaging and dispensing device 1' constituting the invention. For this embodiment and for the next embodiment, the same reference symbols are used to designate elements that are identical to those of the preceding embodiment, and they need not be described again in detail.

Overall the receptacle 2' has the same shape as the above-described receptacle 2, and the cover 9' differs from the previous cover mainly in the shape of the inside of the neck 15. The cover 9' has a tubular skirt 31 inside the neck, which skirt is cut away over two limited angular sectors of its periphery at two diametrically opposite locations to form two substance-passing openings 32 and 33.

The dispensing endpiece 16' mounted to rotate on the neck 15 about the axis X includes an outside wall 16b' from which there projects a rib 34 serving as a marker to indicate which compartment has been selected, and a top wall 16a' that is dome-shaped and that has a central outlet orifice 35 for the substance ...

third embodiment

FIG. 3 shows a packaging and dispensing device 1" constituting the invention.

The device 1" comprises a receptacle 2" housing two unit containers 3" and 4" filled with two respective substances for dispensing separately, e.g. two substances for providing protection against exposure to the sun and having different protection factors.

The containers 3" and 4" are provided at their top portions with pumps 3a" and 4a" (known per se) and shown diagrammatically, which pumps are provided with respective hollow control rods 3b" and 4b".

The pumps 3a" and 4a" may be of the type that does not allow ingress of air, and the containers 3" and 4" may be of the type in which the substance is packaged in a flexible bag that is capable of collapsing onto itself as the substance is dispensed.

The top portion of the receptacle 2" has a setback at the top thereof, and an annular groove 11" is formed in the radially outer surface of the setback for receiving a cap 9" on the receptacle 2" while leaving it fr...

Abstract

The invention relates to a device for packaging and dispensing substances in the form of a liquid, a gel, or a paste form, the device comprising a receptacle having a plurality of compartments for separately storing at least two substances, each compartment having an outlet for the substance, the device further comprising fixing means for fixing a rotary dispensing head on the receptacle to enable the substance contained in a selected compartment corresponding to a predetermined angular position of the head to be dispensed. Said dispensing head has a single dispensing channel provided at its outlet end with a non-return valve suitable for opening under the effect of thrust from upstream substance, and it is shaped to establish selective communication between the outlet of said selected compartment and said dispensing channel and / or to exert selective action on means for extracting substance and associated with said selected compartment.

Description

The present invention relates to a device for packaging and dispensing substances that are in liquid, gel, or paste form, and particularly, but not exclusively, a device for packaging and dispensing a plurality of cosmetic substances for providing protection against exposure to the sun, and having different protection (screen) factors.BACKGROUND OF THE INVENTIONGerman patent application No. 2 444 227 discloses a device for packaging and dispensing two liquid substances, the device comprising a two-compartment receptacle for storing the substances separately, each compartment having a substance outlet opening, and the device having means for fixing a rotary dispensing head on the receptacle enabling the substance contained in a selected compartment corresponding to a predetermined angular position of the head to be dispensed. In that device, the substances are discharged via two respective dispensing channels which open out side by side. Such a device does not provide entire satisfac...
