DESCRIPTION

JAR FOR COSMETICS OR OTHER LIQUID PRODUCTS OR

PASTRY

OBJECT OF THE INVENTION

The invention, as stated in the present specification, falls on a jar for cosmetics or other liquid or pasty products that provides, to the function to which it is intended, advantages and characteristics, which are described in detail below, which they represent an improvement of the current state of the art.

The object of the present invention consists of a jar for cosmetics or other liquid or pasty products, in particular a jar consisting of an external container, of the type having an internal flexible container and extraction system without air intake, comprising a series of improvements that suppose advantages that improve so much the conservation of the product, like his manufacture and his utilization.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of packaging, focusing particularly on the field of configuration containers in the form of a wide-mouth jar with extraction system without air intake.

BACKGROUND OF THE INVENTION

As is known, there are on the market containers for such products that consist of a rigid bottle with an inner flexible bag, which, however, usually have an elongated configuration, in which its height is greater than its diameter, thanks to which collapse the inner bag, to extract the product, occurs laterally, which do not serve for wider and lower containers.

Other packages with said inner flexible bag are described in patents EP 0546898 GB 2184491 and WO 2006/107403 but these are aerosols or cans, in which the neck of the bag and the container is much smaller than its width.

There are also bottles with a piston system to extract the product but, generally, they usually have a structure that is not compatible with that of a jar wider than tall.

There is, however, a jar disclosed in patent FR1252358 which refers to a container with a large opening, associated with an extraction and distribution system without air intake that combines both techniques, that is, the flexible bag and the piston, which, while satisfactorily fulfilling this objective, presents certain aspects that can be improved.

Specifically, a first aspect that can be improved is the problem of contact of the product with the air, since this can lead to premature deterioration of the product, which can be a serious inconvenience, since this type of Packaging is often used in cosmetics and similar products of high economic cost and from which an effective result is expected.

A second aspect that can be improved is the complexity of the The structure of the jar, since, in addition to the flexible bag directly associated with the extraction system valve formed by a more flexible lower part and a semi-rigid upper part, it includes an intermediate rigid tank, and in particular because the lid in which said Extraction system is built from the union of up to three different pieces, all of which, consequently, raises the manufacturing cost of the container, having to add the manufacturing of each of these pieces and their parts to the assembly of the same prior to its addition to the rest of the pieces of the container.

And finally, a third aspect that can be improved is that of the extraction system itself without air intake through which the product emerges when pressed, since the product exits through a groove in a disorderly manner which does not allow adequate control of its withdrawal for use.

The objective of the present invention is, therefore, the development of an improved jar of the aforementioned type to provide them with the necessary technical and structural means that make it possible to overcome said drawbacks.

On the other hand and as a reference to the current state of the art it should be noted that, although as described there are other jars of the type that concerns here, at least on the part of the applicant, the existence of none that has technical characteristics and structural that are the same or similar to those presented by the one claimed here.

EXPLANATION OF THE INVENTION

The jar for cosmetics or other liquid or pasty products that the invention proposes is configured as the solution suitable for the aforementioned objective, the characterizing details making it possible and distinguishing it conveniently collected in the final claims that accompany the present description.

Specifically, what the invention proposes, as noted above, is a jar of the type consisting of an external container that has an internal flexible container containing the product and an extraction system without air intake, comprising several improvements that They improve the conservation of the product and its use.

More specifically, said internal flexible container, in a known manner, has a base, which, when a pressure is exerted on the extraction system located in the upper closing element thereof, which is hermetic and incorporates an extraction valve, ascends by Vacuum effect caused by said valve by pushing the product towards it thanks to the folding on itself that occurs in the flexible material of the area surrounding said base and the side wall of said container.

Therefore, from this already known configuration, the jar of the invention is fundamentally distinguished in the following:

In a first aspect to be understood, in the aforementioned extraction system without air intake, two valves arranged so as to prevent all the product contained in the jar from becoming contaminated upon contact with the air. Specifically thanks to the fact that one is directly associated with the inner space of the inner flexible container, being incorporated in a first membrane that seals the upper part of said flexible container; and another that is associated with an outlet plug located in a second membrane that acts as a top closure with the neck of the jar, such that an intermediate space is generated between both membranes and, therefore, between both valves where certain accumulates quantity of product before its exit and that only this small quantity of product is the one that comes into contact with the air, while the rest of the product contained in the container remains airtight.

The jar is distinguished, in addition, by the fact that the upper edge of the inner flexible container has a flange that fits directly into a groove provided for that purpose inside the jar, the said first closing membrane on its part being placed on it upper, joining the edge of the same by the pressure exerted through the incorporation of the second upper closure membrane, which also has a skirt that fits, by tongue and groove, with the upper edge of the neck of the jar.

Thus, the closure system of the jar comprises only two pieces in the upper area, the two membranes described, and the flange of the inner flexible container, without the need for any additional part to be fixed said flexible container and prevent it from contracting towards the inside of the jar due to the vacuum effect of the extraction system, thus simplifying the manufacture of the container by presenting a smaller number of pieces. In addition, preferably, said inner container is flexible one in a homogeneous manner, that is, in its entire lateral surface, optionally with the exception of the lower base, since it does not require a semi-rigid upper section that prevents its collapse inwards thanks to which is fixed by said flange.

Finally, the jar of the invention is distinguished by also comprising a stopper for the output of the product that allows an exit thereof in an orderly and controlled way when emerging outside through a single hole, instead of through a slot as in the prior art, which facilitates the use of the product by the user.

DESCRIPTION OF THE DRAWINGS

Thus, as seen in said figures, the jar (1) of the invention comprises, in a known manner, an external container (2), which has an internal flexible container (4), in which the product is contained, which optionally it has a rigid base (5), which, when exerting pressure on an extraction system (6) without air intake with an extraction valve (8) provided in a hermetic upper closure (7) of said flexible container ( 4), ascends, pushing the product towards said valve (8), causing the flexible material of the surrounding area to said rigid base (5) and the side wall of the flexible container (4) to fold over itself.

From this already known configuration, the jar (1) is essentially distinguished in that said upper seal (7) and said extraction system (6) comprise two valves, a first extraction valve (8) incorporated in a first lower membrane (9) directly associated with the inner space of the inner flexible container (4), and a second outlet valve (10) located on a second upper membrane (11) defining the upper closure with the neck (12) of the container external (2) there is an intermediate space (13) between both membranes (9, 11) and, therefore, between both valves (8, 10).

In view of the enlarged detail of Figure 5, it can be seen how, in addition, the upper edge of the inner flexible container (4) has a flange (14) that fits directly into a groove (15) provided for this purpose in the inner wall of the container external (2); that the perimeter base of the first membrane (9) of the upper closure system (7) is located on the flat base of said edge of the flexible container (4); and that the second closing membrane (11) has a double skirt (16) that generates a groove (17) that fits with the upper edge of the neck (12) of the end container (2) while pressing on the perimeter of the first membrane (9).

Likewise, the jar (1) also comprises a stopper (18) associated with the product outlet valve (10) in which a single orifice (19) is provided that allows the exit of said product.

In short, what distinguishes the jar (1) and improves it, is that the upper seal (7) and the extraction system (6) comprise two valves (8, 10) incorporated in two membranes (9, 11) between which there is an intermediate space (13); that the upper edge of the inner flexible container (4) is directly coupled to the outer container (2) while the upper membrane (11) fits the upper edge of the neck (12) of the end container (2) and presses on the perimeter of the lower membrane (9); and that, in addition, it comprises a plug (18) with a single orifice (19) of exit of the product.

Preferably, the extraction valve (8), in addition, is incorporated into a recess (20) of the first membrane (9) or lower membrane, located in its central area which defines a depression with respect to the perimeter edge thereof.

Advantageously, the second membrane (11) or upper membrane has a protuberance that defines the extraction system (6), which is offset to one side, the opposite being occupied by another cavity (20) where the second valve ( 10) outlet with the plug (18).

Finally, preferably, the groove (15) of the inner wall of the outer container (2) in which the flange (14) of the inner flexible container (4) fits, is defined in an annular piece (22) attached in a lace of the upper area of said inner wall of the outer container (2).

Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any person skilled in the art understands its scope and the advantages that derive from it.
