DESCRIPTION

airtight container

Technical field

The present invention concerns the field of the containers with airtight closure, the containers being of the type that include a lid and a closing mechanism constituted of shaped metallic wire.

State of the art

Containers provided with a lid imprisoned against the mouth of the container by means of a closing mechanism constituted by a metal wire forming, intercalating a sealing ring between the lid and the mouth of the container to ensure the tightness of the container are known for more than one hundred years closing.

There are many designs of closing mechanisms, being known for example a mechanism similar to that described in GB143520A equipped with an arc-shaped metal wire that passes over the lid and presses it in the direction of the container through its center, having the dome-shaped cover with a protrusion in its center where said metallic wire rests. Lever mechanisms on opposite sides of the container, also constituted by metallic wire, are articulated to that arched metal wire allowing to apply or remove the pressure on said arched wire.

However, this solution presses the central part of the lid, in an area away from the perimeter where the sealing occurs, so that the pressure is not exerted where its effect can be more beneficial to ensure a correct seal, and can cause a seal irregular or deficient. In order to avoid this defect, it is often decided to apply a large pressure in that central part, thus ensuring that there is sufficient pressure throughout the perimeter to guarantee the sealing, but requiring that central part of the lid of an important thickness and a bulging shape to be able to resist that tension and therefore resulting in a very heavy cover, which is therefore uncomfortable, expensive to manufacture and with a significant environmental impact. In addition, this solution prevents stacking of the containers. In addition, the domed cover with a support point in its center forces the metal wire to be also curved so that it can be superimposed on said cover, causing an increase in the length of said metal wire, and causing the support point of the wire with the cover Be far from the lever mechanism that applies the pressure. Both the length of the metal wire, and the distance between the mechanism of

5

30

lever and the point of support are two factors that detrimentally affect the stresses that the wire supports. Since said metallic wire is subjected to stresses that are not only tensile but also flexural, the increase in its length and the distance between its supports produces greater tensions in it, which requires the use of metallic wire thicknesses sized to support these tensions.

Being the length of the metal wire and the distance between its support points increased by the use of a domed cover with central support, the use of a stronger and more expensive metal wire is required to manufacture compared to other solutions that allow to reduce the total length of the wire and that allow to approximate the points of support of the wire in the lid with the lever mechanisms of the sides of the container.

There is also the solution in which the lid is surrounded by a metal ring that is articulated on one side with respect to another metal ring fixed around the neck of the container, allowing the lid to open and close around said joint. At an end diametrically opposite to the joint both metal rings are joined together with a lever mechanism that allows closing the lid by applying pressure, pulling the lid against the container. This solution allows to have a flat lid, but the pressure is applied asymmetrically, only on one side of the lid, so the sealing is irregular and great pressure is needed to ensure proper sealing, requiring a very tight cap thick and heavy to resist and distribute that pressure, which is therefore expensive to manufacture, uncomfortable and with an important environmental impact.

Other solutions are also known in which the wire is articulated in two opposite sides of the edge of the cover, as for example described in EP3205596A1, however this solution also requires a cover with a very thick edge to be able to include this articulated joint, which also results in a very expensive lid to manufacture and with a high environmental impact. Furthermore, in this solution the pressure is applied to the sides of the lid, where the ends of the metal wire that constitutes the closing mechanism are inserted laterally into holes parallel to the sealing ring, so that when the pressure is applied to produce said closure The ends of the wire will be flected by pressing inside the hole irregularly, which would not happen if the pressure were applied on the front of the cover, in a downward direction. In this document, this problem is solved by increasing the pressure necessary to ensure that sufficient pressure is applied throughout the sealing ring, requiring a heavy-duty heavy-duty cap.

Solutions are also known in which the metal wire of the closing mechanism passes through the cover through a hole, however, this solution again requires a cover of great thickness and therefore of great weight.

There are also other solutions that use multiple metal clips or clips that are distributed around the lid, for example the one described in DE3149558, each clip pressing the lid against the container.

However, this solution does not allow simultaneous closure and opening of the entire container, and the quality of the seal will depend on the number and position in which said tweezers or clips are placed, in addition it cannot be guaranteed that all tweezers or clips exert the same pressure on the cover, since each clip may have been used in a different number of times, or have suffered different tensions when placed or removed and therefore have undergone different deformation or fatigue processes, or it may also be that the different clamps or clips correspond to different manufacturing batches. For all these reasons, it is not possible to ensure that a uniform tight seal is obtained throughout the entire perimeter of the lid, which requires an overpressure to ensure that the closure is sufficient at all points of the perimeter of the lid.

In addition, this solution facilitates the loss of said clamps or clips, or that an accidental stroke of little importance can release one or more of the clamps or clips by accidentally releasing the airtight seal of the container.

None of the known solutions provide a hermetic seal that ensures a pressure throughout the contact area between the lid and the mouth of the container, ensuring a sufficient seal that can be opened or closed with a single action, and that at the same time allows Use a lightweight, lightweight lid.

Brief Description of the Invention

The present invention concerns a container with a tight seal that includes:

• a container that defines a mouth;

• a lid with a front and a back intended to be oriented towards the inside of the container, said lid including a perimeter annular wall which, in the closed position, is superimposed on the mouth of the container;

• a sealing ring arranged and clamped between the mouth of the container and the lid;

30

• a closing mechanism movable between a closing position, in which the lid is pressed against the mouth of the container, and an opening position in which the lid is released allowing its opening, the closing mechanism being constituted by formed metal wire defining

or a first region configured to, being in the open position, be superimposed on a part of the front of the lid,

or a second region consisting of two symmetrical portions arranged on diametrically opposite sides of the mouth of the container, each connected to a different end of the first region and configured to, being in the closed position, remain in elastic tension attracting the first region towards the mouth of the container;

or at least a third region configured to, being in the closed position, be coupled to a portion of the container adjacent to its mouth and connected to the symmetrical portions of the second region.

The container and / or the lid may be made of glass or ceramic, although alternatively the use of plastic is also contemplated.

Thus, the closing mechanism is constituted by metal wire formed defining three regions, a first region that is above the closing lid, a second region that remains in elastic position, bringing the first region to the mouth by pressing the lid against said mouth, and a third region connected to the container and serving as a support point for the second region to produce that elastic tension.

It is understood that the closing mechanism is unitary, that is to say that its parts are connected to each other so that the displacement between the closing and opening position occurs jointly and simultaneously. Any closing mechanism consisting of parts that can be released independently of each other is excluded from the definition.

The second region of the metallic wire of the proposal is formed by two opposite portions, one on each side of the mouth of the container, with the same characteristics, thus producing elastic tension of equal strength to the two ends of the first region of the wire, achieving that the force applied by the first region on the cover is as uniform as possible.

The present invention proposes, in a manner not known in the state of the art, that the cover includes at its front at least two opposite support points in a zone coincident or adjacent to the annular wall, and that the first region of the mechanism of The closure is configured to remain, in the closed position, resting on said at least two opposite support points.

It will be understood that the support points on the front of the cover will be accessible support points in a vertical direction, perpendicular to the surface defined by the annular mouth surface.

By pressing the closing mechanism on two opposite points on the front of the cover, it is possible to exert a more uniform pressure on said cover, which ensures a better seal by applying less pressure. By reducing the pressure necessary to ensure a tight seal, the opening and closing of the container is facilitated, while reducing the size and thickness of the elements, especially of the lid, thus achieving a much lighter, more economical and more ecological when you need less material to manufacture.

The first region of the closing mechanism may be shaped by defining a sinuousness coinciding with said at least two support points in the closed position. That is to say that the first region may not be straight but may include those sinuosities that will be configured to coincide with the points of support. This allows better control of the point at which the first region applies pressure on the lid.

In such a case said at least two opposite support points may be defined holes on the front of the cover, where the ends of said sinuosities may be fitted.

According to another alternative embodiment, said at least two opposing support points are located on a protruding annular projection of the front of the cover. In other words, the cover includes a ring-shaped, circular or other shaped projection, on which the support points are placed, which we must remember must be on or adjacent to the annular wall, so that said annular projection will also be located in those same areas.

According to one embodiment, the annular closing projection has a smooth surface with a multitude of support points for the reception of the first region of the closing mechanism.

Alternatively, the annular closing projection will include slits at intervals, each recess corresponding to a support point for receiving the first region of the closing mechanism in said recesses.

According to a proposed embodiment, the perimeter annular wall has a thickness equal to or less than 5mm. This thickness of the wall will be practically the only visible thickness of the lid being in the closed position, so thanks to this feature a light image of the lid will be obtained.

With the annular closure projection located on the wall, the force exerted on the annular closure is transmitted, compressing the annular wall, directly to the mouth of the container, and therefore subjecting the lid to very little stress.

This feature makes it possible to reduce the stresses supported by the lid, or at least the central areas of said lid, thus allowing a thin-cover lid to be used and therefore very light and economical.

Preferably the central portion of the lid, in the area devoid of centering annular shoulder, will have a thickness equal to or less than 5mm.

The lid may include on its back a centering annular projection of smaller diameter than the mouth of the container, intended to be inserted into said mouth while the lid is in the closed position, thus ensuring a correct positioning of the lid with respect to the mouth of the container .

Preferably, the cover will be a pressed cover, providing the centering annular projection of a perimeter annular groove in which the sealing ring is fitted, this sealing ring being attached to the cover also when it is separated from the cover.

According to one embodiment, the annular closing projection has a smooth support surface for receiving the first region of the closing mechanism.

Alternatively, it is proposed that the annular closing projection has a support surface with grooves at regular intervals for the reception of the first region of the closing mechanism in said grooves. In such a case between two contiguous grooves, the annular closing projection will preferably have a ramp bearing surface defining a slope towards said groove to drive the first region of the closing mechanism towards the nearest groove.

If the grooves have a depth equal to or greater than the thickness of the metal wire, the closing mechanism in the closed position will not protrude from the protruding ring annular shoulder, which may allow containers to be stacked on top of each other.

In relation to the closing mechanism it is proposed, according to an embodiment of the invention, that the first region be constituted by a first wire and that the two symmetrical portions that make up the second region be constituted by a second

5

10

25

30

metallic wire independent of the first wire, each of the two opposite ends of the first wire being joined in an articulated manner with respect to the second wire, and the second metal wire being attached to the container by means of two symmetrical articulated joints defined on opposite sides of the mouth by the third region of the closing mechanism. That is to say that a first wire, which integrates the first region, has its articulated ends with respect to a second wire that integrates the two symmetrical portions of the second region of the closing mechanism, said second wire being articulated with respect to the container through the third region of the closing mechanism.

Said third region of the closing mechanism may be defined by the two ends of the second metallic wire inserted in individual housings, which may be defined housings in the wall of the container, or may be defined housings in a collar fixed around the container in a position adjacent to his mouth.

The section of the second metal wire connecting the two symmetrical portions of the second region is proposed to constitute a lever arm that simultaneously drives both symmetrical portions to arrange the closing mechanism in the open position or in the closed position.

That is to say, the displacement of said lever arm will cause the second wire to rotate around the joint attached to the container, causing the displacement of the second region and also of the articulation points between the first region and the second region, thus managing to apply pressure on the lid or its release.

According to an alternative embodiment, the first region, the second region and the third region will be constituted in the same metallic wire, the third region being complementary with an annular groove defined around the mouth of the container. By anchoring said third region in said groove of the container, the second region will be subjected to elastic tension and the first region will be superimposed on the annular shoulder of the lid by pressing it against the mouth of the container.

Preferably the second region is shaped in the form of a spring, to maximize the elastic tension produced by the second region.

Preferably the sealing ring is made of an injection molded material, preferably plastics or other materials of non-natural origin, or for example thermoplastic rubber, and has a thickness equal to or less than 2.5 mm.

Traditionally, materials of natural origin other than plastics are used for this use, but such materials cannot be injection molded but must be obtained by cutting processes that produce elastomeric rings of a considerable thickness, typically greater than 3mm. In addition, these types of natural materials require high pressure to produce their compression, necessary to ensure proper sealing.

The proposed elastomeric seal, however, can be molded without the need for other cutting operations, can have a smaller thickness, and can produce a better seal using a lower compression force.

A preferred feature is that the diameter of the cover is greater than the distance between the annular closing projection of the third region of the closing mechanism, said closing mechanism and said cover being in the closed position. This means that the present invention is directed primarily to wide mouth containers and not narrow mouth bottles.

If the lid were attached to the closing mechanism also in the open position, as in many of the known solutions, the dimensions of the wide mouth containers would not allow the lid to move far enough from the mouth to leave it completely clear. The proposed solution allows the closing cover to be released from the closing mechanism, the closing cover being independent of said closing mechanism.

It is also proposed that the container includes in the extrados of its base at least one groove configured for, said container being stacked on the lid of an identical lower container, to coincide with at least portions of the first region of the closing mechanism in the closed position. of said identical lower container. This feature allows stacking of the proposed containers. Said recess may be defined by recesses made in the thickness of the material that forms the base of the container, or by spaces between projections made in said base and formed with the same material from which the container is made.

It is also contemplated that there may be additional support points between the at least two support points of the lid, such as a central support point located in the center of the lid, or even a plurality of successive additional support points which, together, provide a continuous support surface between the two support points mentioned above.

The proportions of the first, second and third sections of the closing mechanism will be configured to allow complete removal of the first section of the vertical projection of the lid, thus allowing its removal without hindrance.

The attached figures show exemplary non-limiting examples of the present invention.

In Figs. 1,2 and 3 a container 10 is shown which in this example is intended to be a glass container 10. Said container 10 is provided with a cylindrical mouth 11, to which a lid 20 is attached, preferably also made of glass, with a sealing ring 30 interposed to ensure a tight seal between the mouth 11 and the lid 20.

The mouth 11 includes a container opening 13 and an annular mouth surface 14 surrounding said container opening 13.

It will be understood that, although the preferred embodiment is made of glass, both the container 10 and the lid 20 may be made of other materials, such as ceramics or even optionally contemplated the use of plastic.

The lid 20 is a flat lid formed by a flat circular glass about 5mm thick that defines an upwardly oriented obverse and a downwardly oriented inward direction of the container 10. The circular glass has an outside diameter equal to the diameter outside of the mouth 11 of the container 10, so that when it is superimposed it is flush out externally.

From the back of the circular glass, a centering annular protrusion 23, in the form of an annular protuberance concentric to the circular glass, protrudes formed by the same glass as the rest of the cover 20 and with an outer diameter smaller than the inside diameter of the mouth 11 of the container 10, so that said centering annular shoulder 23 is inserted into the mouth 11 of the container 10 when the lid 20 is in the closed position.

The part of the circular glass comprised between the centering annular projection 23 and the outer perimeter edge of the lid 20 forms an annular wall 21, which in the closed position is superimposed on the mouth 11, and whose thickness is equal to or less than 5mm.

The obverse of the lid 20 incorporates an annular closure projection 22 in the form of an annular protuberance concentric to the rest of the lid 20. Said annular closure projection 22 is formed by the same glass that constitutes the rest of the lid 20.

Preferably said annular closure projection 22 protrudes from the front of the cover 20 in a position vertically coincident with the position occupied by the centering annular projection 23 located on the reverse of the cover 20 and / or with the annular wall 21, that is to say he

5

25

30

annular closing projection 22 is totally or partially superimposed on the annular projection oentrator 23 and / or the annular wall 21.

In order to keep the sealing ring 30 attached to the lid 20 also when it is separated from the container 10, it is provided that the annular shoulder or inlet 23 incorporates a perimeter annular groove in which the sealing ring 30 is partially fitted, being thus fixed to the cover 20.

Obtaining the described cover 20, incorporating said perimeter annular groove in the centering annular shoulder 23, requires that the cover 20 be produced with pressed glass in a mold formed by more than two mold parts.

In order to keep the lid 20 attached to the container 10, a closing mechanism 40 formed by formed metal wire is included which, in a closed position, is partially superimposed on the lid 20, pressing it on two diametrically opposite support points 25 of the annular shoulder of closure 22 and against the mouth 11 of the container 10, achieving a tight seal.

According to an embodiment shown in Figs. 1,2 and 3, the closing mechanism 40 consists of a first U-shaped wire with an inverted flat bottom, and a second U-shaped wire with a rounded bottom that includes portions 42a and 42b symmetrical loops in areas near their ends.

The second wire has its ends inserted in two grooves arranged on opposite sides of the outer container 10, adjacent to the mouth 11 providing an articulated joint between the second wire and the container 10. The first wire has its ends inserted in each portions 42a and 42b opposite in the form of loops of the second wire, on opposite sides of the outside of the container 10, providing an articulated joint between the first wire and the second wire.

In the present embodiment said grooves are defined in a metal collar fixed around the container 10, but it is also contemplated that they may be grooves formed in the glass wall of the container 10, as shown in Figs. 5 and 6.

The first wire is, in the closed position, superimposed on the annular closing shoulder 22 of the cover 20, and the second wire allows, according to its position, to move the symmetrical portions 42a and 42b in the form of loops where the first wire is articulated in a vertical direction managing to exert a vertical tension of the first wire on the

5

25

30

annular closure closure 22 of the lid 20 against the mouth 11 of the container 10, ensuring a tight seal thereof.

The first wire constitutes a first region 41 intended to press the lid 20 against the container 10, the portions 42a and 42b of the second wire constitute a second region 42 intended to produce an elastic tension attracting the first region 41 down, and the ends of the The second wire articulated with respect to the container 10 forms a third region 43 of the closing mechanism 40 intended to connect the closing mechanism 40 to the container 10, and which serve as a support point for subjecting the second region to elastic tension.

The portion of the second wire between the symmetrical loop portions 42a and 42b is a lever arm that allows simultaneous and symmetrical actuation of the two symmetrical portions 42a and 42b, placing the closing mechanism 40 in the closed or closed position. in the opening position in which the lid 20 is released allowing its removal from the mouth 11 of the container 10.

According to another intended embodiment shown in Fig. 4, the closing mechanism 40 consists of a single U-shaped wire with an inverted flat bottom.

Said metallic wire will have a first region 41 in its central zone, intended to be supported on the annular closing shoulder 22 of the cover 20, a second region defined in two portions 42a and 42b located in areas close to the ends of the wire, intended to be subjected to a certain elastic tension when the closing mechanism 40 is in the closed position, and a third region corresponding to the two ends of the wire, said third region being complementary with an annular groove arranged around the mouth 11 of the container 10 , intended to fit said third region in its interior, and therefore serving as a support point for the second region to provide elastic tension to the first region, which transmits it to the cover 20 through two opposite points of the annular shoulder closing 22.

Said annular closure projection 22 may be smooth, allowing the first region 41 of the closing mechanism 40 to rest in any position, or it may include grooves 24 provided so that the first region 41 of the metal wire is embedded therein, in predetermined positions. .

An alternative version of this same solution, shown in Fig. 7, proposes that the two ends of the wire forming the closing mechanism be placed on the cover 20, the first region 41 being combined together. Each end will be folded down defining a sinuosity, each pressing the lid at a support point 5 25. Such support points may be placed in holes or recesses of the lid 20.

According to one embodiment, for example the one shown in Figs. 5 and 6, the first region 41 of the closing mechanism 40 may include sinuosities whose ends coincide with the support points 25.

It will be understood that the different parts constituting the invention described in one embodiment may be freely combined with the parts described in other different embodiments even if said combination has not been explicitly described, provided there is no harm in the combination.
