Description

The The invention relates to a device or organ intended for this purpose is the closure of a container in general according to the preamble of claim 1 and a packaging in particular to ensure. The document FR 587800 A describes such a device.

The The invention more particularly relates to a closure member which except its Main function of the effective closure of the opening of the container, with which it is firmly connected or attached to, is also an active function can ensure which can be different and in particular dehumidifying, moisturizing, oxygen absorbing, carbon dioxide absorbing or releasing, absorbing or distributing odors or odors or can also develop anti-mold properties.

It is well known today, dehydrating in certain applications or to use dehumidifying products with the goal of being in one to absorb moisture contained in certain volumes. Actually proves For a certain number of products or applications, the room humidity as harmful and thus must be avoided at all costs.

in the Food sector, the problem can also occur once powdery Products are used such as chocolate powder for the Breakfast, milk powder, Potato flakes for the preparation of puree, Etc....

So long the packaging containing these products is not opened, These are usually kept tightly sealed, especially against moisture protected, for example, by mistake with a lid.

As soon as However, the packaging is opened for the first time, which is forced to at least partial detachment the lid leads, allows the type of closure used in general is no longer the assurance this tightness with respect to the ambient air and consequently in relating to the moisture contained in it, so that a clumping of the powder and generally of the dry substance which forms in Form of lumps occurs, and in parallel is a flavor loss of the To watch the product.

Around overcome this disadvantage are different solutions been proposed.

The The first of them is in the production of packaging small dimensions, for example, the single-portion type, for the purpose a quick and in particular immediate consumption of the content every serving on opening. In this way, one evidently eliminates the influence of Moisture on the product contained in it.

hereby be for a certain amount of the commodity alone in relation to the costs on the packaging considerably elevated. To such an extent, that at certain products, the packaging costs more than the product itself.

at other applications such as potato flakes suggested within a larger packaging bag too distribute, which is the average consumption of one, two or a limited number of people. In this way In turn, the product is not exposed to moisture because it is consumed immediately.

Though conserves this solution the unused product outside the action of moisture, leads however also a further increase in costs.

It has also been proposed, at the bottom of conventional closures To insert dehumidifiers which is so after resealing of the container by means of said closure can exert an effect which aims to absorb the moisture of the air, which has penetrated into the interior of the volume of said container, released through the partial consumption of its contents.

however is the danger that that in the container stored product comes into contact with the dehumidifier or desiccant, not equal to zero, and for reasons hygiene and toxicity is sought at all costs, one to eliminate such danger.

The Invention is to propose a resealable lid, which comprises such means without any danger the contact between the contents of the container to which it is attached and the active substance used inside the lid.

• – zunächst einen Umfangsring, welcher dazu bestimmt ist, nahe dem oberen Ende des Behälters angebracht zu werden, und die Zugangsöffnung zu diesem begrenzt;
• – und einen an dem genannten Ring angebrachten Deckel, wobei der genannte Deckel ein Behältnis umfaßt, welches einen Wirkstoff aufnehmen kann, wobei das genannte Behältnis mittels eines Verschlußorgans verschlossen ist.

This closure device for a container comprises:

• - First, a peripheral ring, which is intended to be mounted near the upper end of the container, and the access opening to this limited;
• And a lid attached to said ring, said lid comprising a receptacle adapted to receive an active agent, said receptacle communicating with said receptacle a closure member is closed.

According to the invention the closure organ of the container from a porous one or microperforated film or cap, and the peripheral ring takes a cap which is intended to contain the contents of the container close to a first use. In this design is the closure organ of the container, which The active ingredient includes, intended to be in close and intimate contact with said closure lid to step when the lid is in the closed position, so that the dense Closure of the said container guaranteed is to any change to avoid its properties. This tightness is also elevated, if a slight pressure from the container on the cap under the action of the lid.

According to one first embodiment the invention is the closure member of the container porous and in particular air-permeable, so that the impact the active substance is allowed on the air, whether it be that It's all about absorbing the moisture, be it an anti-mold treatment carried out shall be.

According to one second embodiment the invention is the closure member the container is microperforated, in particular to allow that by this specific only certain components pass, in particular in the context of oxygen absorption, or even to an absorption and then re-release the moisture during use of rehydration agents as active ingredient.

The Way in which the invention can be carried out and which The resulting benefits are better understood from the following and not restrictive with the help of the attached Figures given embodiment out.

1 is a schematic perspective view of the upper part of a container, which uses the lid according to the invention, wherein it is in the open position.

2 is one too 1 analogous view according to a second embodiment of the invention.

3 is a schematic perspective view of the upper part of the container 1 , where here the lid is closed.

The The following example refers more specifically to a container whose Volume after first opening protected against moisture should be kept.

Such a container 1 may be of any kind and have any cross-section. In particular, it may be rigid and, in this case, be made of a relatively thick cardboard, which may be coated with aluminum.

He may also be made of a flexible material, such as in particular a sheet of plastic, which is intended to the body of the packaging to build. This bow is the desired shape by means of a mandrel and a pair of pliers which grips the outer edges of the bow with it they overlap one another edge to edge, typically over one Width of two millimeters, and then her firm connection over her entire height is ensured, this fixed connection typically by ultrasound or by gluing or hot glueing accomplished becomes.

This Bow is thus made of synthetic material, or of cardboard, made, which is treated such that ultrasonic welding or heat sealing allows becomes. The body thus produced takes a floor at its base which typically consists of a shell, also made of a synthetic material and its shape and dimensions of course the shape and dimensions of during the previous stage corpus produced correspond.

Of the The circumference of this shell has a throat into which the lower End of said body should be used. After inserting it goes one over to an adhesive or welding phase, um in this area to ensure the required tightness and hermetic seal.

The lid according to the invention 2 is typically made of plastic and in particular of polypropylene by spraying in one or more stages.

It comprises as a basic component a, in the present case stiff, circumferential ring 3 , which is intended to be in the region of the upper end of the container 1 to be fitted around its circumference, this upper end forming the access opening to the contents of said container and also the opening for emptying it.

This peripheral ring 3 takes a cap 4 which is intended, in a known manner, the tight closure of the contents of the container 1 to ensure before the first use. For this purpose he is with a radial brim 11 provided, which advantageously was obtained by molding and is intended as a support for said closure cap 4 to serve, especially when it is attached. This peripheral ring 3 is attached to said upper end of the body by any conventional means, such as, in particular, gluing or heat sealing.

The actual lid 6 is in the range of a hinge 5 on the peripheral ring 3 hinged. However, in another embodiment of the invention, not shown, said lid may be in the region of one of the edges of said ring 3 be clipped.

According to a feature of the invention, the floor 10 of the lid 6 a container 7 which is advantageously made by molding and intended to contain an active ingredient, typically a dehumidifying agent 9 such as to take up and contain a silica gel or clay.

The lid 6 , the circumferential ring 3 and the container 7 advantageously form a one-piece arrangement, which is made of plastic and by molding.

The container 7 is thus limited by an annular projection, said projection is advantageously made by molding and starting from the bottom 10 of the lid 6 runs. It runs over a slightly greater height than the height of the lid, as well in 3 can be seen. In a variant of the invention, not shown, the lid has a partial opening, so that, for example, a spout is obtained. In this configuration, the container is disposed under the immovable part of the lid, wherein the closure lid for sealing the container is then removed by moving in the manner of a rail system.

According to a further, not shown embodiment of the invention, said container is not made by molding with the lid, but at the bottom 10 said lid 6 attached, in particular by clipping or snapping in the region of a purpose for this purpose, in particular by molding in the region of said soil 10 attached ring. This embodiment has the advantage that the container 7 with an active ingredient 9 can be filled, regardless of the manufacture or the arrangement of the lid 6 on the packaging, which is intended to receive it.

The container 7 is by means of a porous film or cap 8th locked. It can be made of polypropylene and generally of plastic, but also of paper.

By porosity is meant the ability of the film in question to contain the moisture-containing ambient air into the interior of the container 7 so that the active substance contained therein can effectively absorb this moisture. In other words, the said container 7 Ambient air enter its interior. As a result, the moisture carried by her by the dehumidifier contained in it 9 absorbed.

According to a feature of the invention, the relative height of the container 7 in relation to the ground 10 of the lid 6 chosen so that the film or cap 8th in intimate contact with the in the area of the peripheral ring 3 attached cap 4 occurs when the lid is closed ( 3 ), in particular by snapping on the peripheral ring 3 ,

This intimacy is advantageously enhanced by a slight increase in the height of said container 7 such that a slight bend of the closure lid 4 is caused in the order of 2/10 to 3/10 mm under the action of pressure, thus by the container 7 following the closing of the lid 6 is exercised.

In addition, the tension of the cap 4 under the influence of the container 7 when closing the lid 6 pressure applied to become the Stützkrempen 11 of said closure cover upwardly, and it is chosen a suitable material thickness to form them, so that an elastic effect, also directed upward, is ensured. In this way, even under the influence of the container 7 exerted pressure of the cap 4 constantly curious and thus provides a very firm contact between the film 8th and the cap 4 her and thus provides the tightness of the container 7 despite the porous nature of the film 8th for sure.

In other words, before a first use of the container 1 the one in the container 7 contained active substance 9 not exposed to the external environment, and the properties for which it was selected are thus not changed.

After first opening, thus opening the lid 6 , becomes the cap 4 removed, so that due to the porosity of the film 8th no tight closure of the container 7 more is available. So fulfilled when closing the lid 6 the active substance 9 then its function and ensures a dehumidifying function in the example described.

Obviously, the active ingredient may be another egg characteristics depending on the contents of the container 1 fulfill. It may, for example, be a rehydration agent or an oxygen absorber. In this design is the movie 8th microperforated, the dimensions of the perforations then being dependent on the size of the molecules that are to be passed through.

Of the Active substance can also absorb or release carbon dioxide. It can also be an absorber or, on the contrary, um a diffuser of odors or aromatic essences which are suitable, the odor in the container contained product when opening the container to reinforce.

In another, related to 2 described embodiment, the container 7 not from an annular projection, but from the whole of the bottom of the lid 6 , In this design, the film or cap runs 8th essentially along the entire surface of the soil 10 to ensure its shutter function. The film 8th is mounted on a radial brim, which is in the region of the inner side surface of the lid 6 is mounted at the desired height.

consequently are due to the big ones Simplicity of making the lid the numerous applications conceivable, for which he is determined.

Due to the technical principle used, it is possible to have at the same time an endless resealable lid, which ensures its main function of closing a container, while giving it a well-defined function, such as dehumidification, without compromising the properties of the active ingredient in question first use, due to the arrangement of a film 8th which cooperates with the closure lid for sealing the contents of the container or the packaging. In this way it is possible to optimize the life and storage time of products, especially food.
