DESCRIPTION

CONTAINER WITH COVER UNDER A THREADED CLOSURE MECHANISM Field of Technology

The present invention concerns the field of containers with a lid attached to a threaded closure mechanism, the containers being of the type that include a mouth surrounded by a thread, a lid and a closing mechanism constituted by an inner disk hollow with a perimeter skirt provided with a crimp configuration complementary to the thread of the container.

The closing mechanism surrounds the lid and imprisons it against the mouth by means of the threaded joint between the crimping configuration of the closure mechanism and the thread of the container, ensuring a correct sealing of the lid with the container.

State of the art

Containers fitted with a lid imprisoned against the mouth of the container have been known for more than a hundred years by means of a closing mechanism consisting of a hollow interior disk with a perimeter skirt provided with a complementary crimping configuration with a thread of the container .

The oldest and most recognized containers of this type are those known as Mason containers, which marketed this type of containers since the end of the 19th century using glass containers and lids.

There have been records of these types of containers since then, incorporating small variations or improvements to the system. For example, document US1602346A, or document US8550268B1 describe containers of this type.

However, in the known containers of this type the closing mechanism is not attached to the lid, whereby after opening the container the lid is separated from the closing mechanism.

Brief Description of the Invention

The present invention concerns a container with a lid attached to a threaded closure mechanism that includes:

• a container provided with a mouth that includes a container opening, an annular mouth surface surrounding said container opening, and a thread surrounding said mouth externally;

• a cover with a front and a back, said cover including a perimeter annular wall which, in the closed position, is superimposed on the annular surface of the mouth of the container, and of at least one protruding central projection on the front of the lid;

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

• a movable closing mechanism between a closing position and an opening position, the closing mechanism being constituted by a tubular skirt with a first open end and with a second end closed by an annular disk connected by its outer perimeter to the tubular skirt , said annular skirt being provided with a crimping configuration complementary to the thread of the container; where

or the tubular skirt surrounds and defines a first insertion passage whose size is equal to or greater than the outer size of the annular wall of the lid and whose depth is greater than the thickness of the annular wall; Y

or the annular disc surrounds and defines a second insertion passage in its center, the size of which is smaller than the size of the first insertion passage and the outer size of the annular wall and greater than or equal to the size of the at least one central shoulder of the lid ;

where in the closed position the annular wall is inserted in the first insertion passage and in contact with the annular disk of the closing mechanism, the at least one central projection is inserted in the second insertion passage, the annular skirt is arranged around of the mouth and the crimping configuration of the closing mechanism is coupled to the thread.

The threaded seal determines that the thread is circular, and therefore the mouth will also preferably be tubular. This determines that, preferably, the general configuration of the annular wall of the lid and the closing mechanism also have a general circular geometry to adapt to said tubular mouth.

The back of the lid is intended to be, in the closed position, oriented towards the container opening, the obverse being the opposite face of the lid, in which the at least one central projection is located.

The closing mechanism is provided to screw the crimping configuration into the thread of the container, pressing the lid against the container achieving a tight seal thereof. More specifically, the annular disk of the closing mechanism will be in the closed position superimposed on the annular wall of the lid, pressing it against the annular surface of the container's mouth.

It is further understood that when it is specified that two related or embedded elements are of equal size, it is also contemplated that there are small differences in size that make it necessary to apply a certain force and a small elastic deformation of one of the elements for get them to fit or be inserted.

The sealing ring will preferably be of a flexible or elastomeric material, but impermeable to air, such as plastics, soft plastics, rubber, latex or rubber.

The invention further proposes that, in a manner not known in the state of the art, include:

a retaining element connected to the closing mechanism producing a throttling of the first insertion passage retaining the annular wall attached to the closing mechanism preventing the removal of the cover; or

a retaining element is connected to the closing mechanism producing a throttling of the second insertion passage, with portions of the retaining element being inserted in portions of lateral grooves located in areas of at least one central projection of the lid located at two different halves of the lid , retaining the at least one central shoulder attached to the closing mechanism preventing the removal of the lid.

That is to say, the inclusion of a retaining element is proposed which, in collaboration with the closing mechanism, reduces the free section of the first or second insertion passage of the closing mechanism preventing the removal of the cover inside the closing mechanism.

This allows the closing mechanism to remain attached to the cover even in the open position, preventing the loss of one of these elements, and preventing the accidental fall of the cover inside the closing mechanism, which could cause its breakage in case if said lid is made of a fragile material such as glass or ceramics.

When opening the container, the rotation of the closing mechanism in collaboration with the thread produces a distance of the closing mechanism from the annular surface of the container's mouth. The proposed retaining element will cause said distancing to also drag the cover away from the annular mouth surface, which will help to break

the vacuum that could exist inside the container while it is unscrewed, facilitating the entry of air inside.

In the closed position, the cover is inserted into the closing mechanism through the first insertion passage, the annular wall being in contact with the annular disk that closes the bottom of the first insertion passage, and the at least one annular shoulder being inserted. in the second insertion passage.

Since the depth of the tubular skirt is greater than the thickness of the annular wall, in the closed position only a part of the tubular skirt will remain around the annular wall, the retaining element being located in the rest of the tubular skirt that will be below that mentioned. annular wall, the container being upright with its mouth at the upper end.

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

According to a first alternative of the invention, the retaining element will produce a narrowing of the first insertion passage to a size smaller than the size of the annular wall, thus preventing said annular wall from being removed from the first insertion passage, the closure mechanism being attached to the annular cover

Alternatively, the retaining element will produce a narrowing of the second insertion passage. However, in this case, for the retention of the lid to occur, it is necessary that said at least one central shoulder includes portions of lateral grooves located at least two different halves of the lid, and that the retaining element is at least partially inserted into said portions of lateral grooves.

For the manufacture of said lid with the groove portions it is proposed, preferably, the use of pressed glass in a mold provided with more than two parts.

In any case, the retaining element reduces the size of the insertion passage through which the cover has been inserted into the closing mechanism, preventing it from being removed again.

According to an embodiment of the proposed invention, the retaining element will be an elastically deformable element.

In one embodiment, said elastically deformable retaining element will be attached under elastic tension around the central shoulder of the cover, the retaining element being partially inserted in said lateral grooves, being connected by contact to the annular disk of the closing mechanism.

According to another embodiment, the elastically deformable retaining element will be attached under elastic tension to the tubular skirt surrounding it externally. In such a case the tubular skirt will include openings through which portions of said retaining element are introduced into the first insertion passage by throttling it and reducing the free passage section.

Alternatively, the elastically deformable retaining element may be inserted under pressure into the first insertion passage, the tubular skirt including openings or seats in which portions of said retaining element are fitted by fixing the position of the retaining element within the first insertion passage. That is to say, the retaining element will be introduced inside the first compressed insertion passage and its expansion will keep it pressed against openings, or in seats made in the wall of the tubular skirt where it will be partially inserted preventing its accidental removal.

The proposed elastically deformable retaining element may be for example an annular spring or an elastic ring, or an open ring, for example made of a metallic or plastic material.

According to another embodiment of the invention, the retaining element may be a portion of the plastically deformed closure device producing a bulge that throttles the first or second insertion passage.

The closing mechanism may be, for example, metallic or plastic, which allows to create said plastic deformation by applying pressure, or pressure and heat, after insertion of the cover in the first insertion housing.

The crimping configuration of the aforementioned closing mechanism is proposed to be a thread formed in the tubular skirt, said thread being complementary to the thread of the container to allow its joining.

Alternatively said crimping configuration may consist of a plurality of thickening arranged around the first open end of the tubular skirt, said thickening projecting from the tubular skirt into the first insertion passage, said plurality of thickening being complementary to the thread of the container . In the event that the closing mechanism is metallic, said plurality of thickening may be formed by a fold of the edge of the tubular skirt.

In order to help the opening movement of the closing mechanism, by unscrewing it from the mouth, produce the rupture of the vacuum inside the container,

5

they also propose other characteristics that cause the joint rotation of the closing mechanism with the lid. The combination of traction away from the lid of the container, together with its rotation, will ensure that the tight seal is broken and the air enters the container.

To ensure that the closing mechanism and the lid rotate together it is proposed that at least:

• the first insertion passage and the perimeter zone of the annular wall; or

• the second insertion passage and the perimeter zone of the central shoulder

have a complementary non-circular geometry and size, both elements being fitted preventing a relative rotation of the closing mechanism with respect to the lid.

It is understood that a complementary size is that which allows the insertion of an element into the corresponding passage, even if to produce said insertion certain force and elastic deformation is necessary.

It is also understood that a complementary size that prevents relative rotation is that size that will cause interference to the insertion passage with the element inserted therein during its rotation path. For example, it is considered that, in most geometries, a difference of size equal to or less than 3mm should provide that effect, unless it is very close to circular geometry geometries.

It is considered that a concentric circular geometry with the thread will not allow to obtain the desired effect of producing the joint rotation of the closing mechanism with the cover. However, other geometries are considered to produce such an effect.

Therefore two solutions are proposed to achieve the joint rotation of the closing mechanism with the lid.

On the one hand it is proposed that neither the central protrusion of the cover nor the second insertion passage be circular, both elements of complementary geometries and sizes and therefore producing a coupling that prevents their relative rotation.

On the other hand it is proposed that neither the annular wall nor the first insertion passage be circular, both elements being complementary geometries and sizes and therefore producing a coupling that prevents their relative rotation.

As a non-limiting example, it is proposed that the central projection has a polygonal, elliptical, alveolar, starry, cross, icon, letter, word, number or circular truncated shape or circular shape with indentations in its perimeter .

30

Also by way of a non-limiting example that proposes that the perimeter zone of the annular wall has a polygonal, grooved, alveolar shape or a truncated circular shape or circular shape with grooves in its perimeter.

According to another embodiment of the invention, the at least one central shoulder includes at least two diametrically opposed portions defining between them a central passage that diametrically crosses the lid and passes through its center, said two diametrically opposite portions of support planes perpendicular to the front of the lid.

This allows a user to introduce a lever element, such as a knife, a handle of a cutlery, or a stick in said central passage, the lever element resting on the lid. A rotation applied on that lever element will cause it to come into contact with the support planes of the two diametrically opposite portions of the central shoulder, allowing a torque to be applied to the lid, producing its rotation with respect to the rest of the container.

Alternatively or additionally to the above characteristics, it is also proposed to include discrete protrusions of a thickness less than the thickness of the sealing ring in:

• the face of the annular wall facing the sealing ring; or

• the annular mouth surface facing the sealing ring, or

• the face of the sealing ring facing the annular wall; or

• the face of the sealing ring facing the annular surface of the mouth.

Said protuberances will not prevent the hermetic sealing of the container, since having a thickness less than the thickness of the sealing ring, the crushing of said sealing ring under the force exerted by the closing mechanism can assume said irregularity that the extrusion supposes, maintaining the tight seal, especially being the protrusion of rounded edges and low slope. Preferably the thickness of said protuberance will be less than half the thickness of the sealing ring.

However, once the cover of the closing mechanism is released, the same elastic force of the sealing ring will push the protuberance and facilitate the spontaneous rupture of the hermetic seal allowing the entry of outside air through spaces adjacent to the discrete protrusions.

It is further contemplated that, preferably, said discrete protrusions will each consist of an elongated lump that crosses the face on which they are formed from the perimeter

5

10

fifteen

twenty

25

30

outside to the inside perimeter of the element in which they are formed, thus facilitating the entry of air from the outside to the inside of the container when the closing mechanism is released.

Said protuberances each preferably consist of a lump that crosses the face in which they are formed from the outer perimeter to the inner perimeter of the element in which they are formed.

The lid may also include a rear centering projection of smaller diameter than the container opening, intended to be inserted into said mouth while the lid is in the closed position, and where the centering rear projection will consist of an annular perimeter groove. in which the sealing ring will be partially fitted.

This feature ensures that the sealing ring remains attached to the lid also in the open position, preventing it from being lost.

According to a further proposed embodiment, said annular wall of the lid has a thickness equal to or less than 5mm, this being a reduced thickness that allows obtaining a lid assembly and a low height closing mechanism.

The sealing ring will preferably have a thickness equal to or less than 2'1mm, which will also help reduce the visible part of the lid assembly and closing mechanism, since this thickness is less than usual.

In addition, this reduced thickness will require a lower pressure of the closing mechanism to obtain a tight seal.

Other features of the invention will appear in the following detailed description of an exemplary embodiment.

Detailed description of an embodiment example

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

Figs. 1, 2, 3, 4,6, and 7 show a container 10 which in this example is intended to be a glass container 10. Said container 10 defines a cylindrical mouth 11 around which there is a thread 12 made of the same glass that constitutes the container 10. The mouth 11 contains an annular mouth surface 14 surrounding a container opening 13 giving access to the interior of the container.

The opening 13 is closed by a cover 20 which is proposed that in this example it should also be made of glass, disk-shaped, plate or circular terrine. On the periphery of said lid 20 there is an annular perimeter wall 21 which, in the closed position, is superimposed on the annular mouth surface 14 of the container 10, the rest of the lid 20 being smaller in diameter than the diameter of said 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.

Between the annular wall 21 and the mouth 11 there is a sealing ring 30 which, being the lid 20 in a closed position, is trapped between the annular wall 21 and the mouth 11, providing a tight seal. Preferably this sealing ring 30 will be of a flexible elastomeric material which, when pressed between the lid 20 and the container 10 will be pressed producing a tight seal.

The cover 20 includes on its front not facing the mouth 11 a central projection 22 protruding from the plane defined by the annular wall 21.

5

10

fifteen

twenty

25

30

The lid 20 may optionally also include a centering rear shoulder 23 on its back facing the container 10, said centering shoulder 23 being smaller in diameter than the opening 13 of the container 10.

In these examples the central projection 22 and the central centering projection 23 both have a cylindrical wall shape with approximately the same diameter, so that they are one above the other.

The annular wall 21 is located between said central projection 22 and the central centering projection 23, so that said projections form a step both on the front and the back with respect to the annular wall 21.

To clamp the glass lid 20 against the mouth 11 of the glass container 10, producing a hermetic seal, a closing mechanism 40 is used consisting of a flat circular disc 41 of hollow center which extends at its periphery by means of an annular skirt 42 cylindrical.

Said annular skirt 42 includes a crimping configuration 43 that will be complementary to the thread 12 of the container 10, so as to allow the closing mechanism 40 to be screwed to the container 10, thereby pressing the annular wall 21 against the mouth 11 of the container 10, ensuring a tight seal.

The crimping configuration 43 can be, for example, a thread formed by the inner face of the annular skirt 42, complementary to the thread 12 of the container 10, as shown in Figs. 1, 2 and 3.

Alternatively, it is contemplated that the edge of said annular skirt 42 has at its furthest end of the disc 41, a discontinuous thickening configured to crimp with the thread 12 of the container as a crimping configuration 43, thus providing the hermetic seal of the lid 20 with the container 10.

A crimp configuration 43 is shown in Figs. 4, 6 and 7 formed by a bend in the edge of the tubular skirt 42, which will preferably be metallic in this embodiment, for example stainless steel.

In any case, the closing mechanism 40 defines a first insertion passage 44 corresponding to the space surrounded by the tubular skirt 42 and which is partially closed at one end by the annular disk 41, provided for the insertion of the cover 20 and defines

5

10

fifteen

twenty

25

also a second insertion passage 45 corresponding to the central hollow of the annular disk 41 provided for insertion therethrough the central shoulder 22 of the cover 20.

Therefore, the first insertion passage 44 will have a size equal to or greater than the maximum size of the cover 20, corresponding to the perimeter of the annular wall 21, said size being sufficient to allow the insertion of the cover 20 into the closing mechanism. 40

The second insertion passage 45 will be of a size equal to or greater than the size of the central projection 22 of the glass cover 20, so that said central projection 22 can be inserted into the second insertion passage, allowing the rest of the annular disk 41 may rest on the obverse of the annular wall 21.

It will be understood that the expression "equal size" also covers those cases in which there is a small difference in size that requires the application of a certain force or even a small deformation to achieve the insertion.

According to the embodiments shown in Figs. 1, 2 and 3 the central projection 22 has a height greater than the annular disc 41, thus achieving to protrude above it when it is supported on the annular wall 21.

Around the central projection 22, at least lateral groove portions 24 accessible from the side of said central projections 22 are included, above the position of the annular disk 41, when in the closed position.

Said portions of lateral grooves 24 may completely surround the central shoulder 22, or it may consist of a plurality of separate partial grooves all arranged in the same plane around the central shoulder 22, at least two of said partial grooves being located in different halves of the lid. 20. This arrangement ensures that the coupling of the cover 20 to the closing mechanism 40 is secure throughout the perimeter.

According to the present embodiment shown in Figs. 1, 2 and 3 the invention proposes to include a retaining element 50 at least partially surrounding the protruding portion of the cylindrical wall of the central shoulder 22, with portions of the retaining element 50 being at least partially inserted into said lateral groove portions 24, at the once other portions of the retaining element 50 will be attached to the annular disc 41 of the closing mechanism 40, managing to anchor the cover 20 to the closing mechanism 40.

25

According to the embodiment shown in Figs. 1 and 2 the retaining element 50 will consist of an elastic ring, such as an open metal ring or a rubber ring or other elastic material, inserted under elastic tension in the lateral groove portions 24 of the central shoulder 22 of the cover 20. Said retaining element 50 will be partially supported on portions of the annular disc 41, the annular disc assembly 41 and retaining element 50 determining a narrowing of the second insertion passage 45, the cap 20 being therefore retained in the closing mechanism 40.

In the present example said retaining device 50 consists of an open metal washer, with a certain elastic capacity. To place said metal washer around the central shoulder 22, it must be opened elastically, being partially retained within the groove 24 under elastic tension.

The groove 24 will preferably be continuous around the central shoulder 22, but alternatively it is contemplated that it may consist of different separate groove sections arranged around the central shoulder 22.

In any case, when the retaining device 50 is coupled to the slot 24, part of said retaining device 50 will project radially from the periphery of the central shoulder 22, so that the central hole of the disc 41 of the closing mechanism 40 is of a smaller size that said retaining device 50, thereby preventing the separation of the closing mechanism 40 from the rest of the glass cover 20.

This prevents parts of the assembly from being lost, while allowing the closing mechanism 40 to be pulled, dragging the glass lid 20 with it to overcome the void that could exist inside the container 10, thereby allowing unscrew and remove the lid 20 glass in one operation.

The embodiment shown in Fig. 4 and 5 is similar to the previous one, but in this case the retaining element 50 in the form of an elastic washer surrounds the tubular skirt 42. At certain points the tubular skirt 42 has openings through which an appendix of the retainer element 50 will be inserted into the first insertion passage 44, reducing its size to a size smaller than that of the annular wall 21, and thus preventing the removal of the cover 20 from within the closing mechanism 40.

30

In Fig. 5 another view of this same embodiment is shown, in which it is appreciated that said appendices are folds of the elastic washer, which in this case is proposed to be metallic.

Alternatively, the washer may be made of plastic, or of elastic material such as rubber, rubber or latex, then including said appendages as extensions of the same washer.

Another proposed embodiment, shown in Fig. 6, consists of the insertion of the retaining element 50 in the form of an elastic washer into the first insertion passage 44, said retaining element 50 being subjected to elastic tension in its interior pressing against the intrados of the skirt tubular 42.

In said intrados a seat will be provided, for example in the form of an annular groove, or of point openings, located below the annular wall 21, the container being in an upright position. The retaining element 50, or parts thereof, will be partially inserted in said seat or in said openings by fixing the position of the retaining element 50 within the closing mechanism 40.

Another alternative embodiment is that shown in Fig. 3, in which the retaining element 50 is not a ring, but is a portion of the closing mechanism 40 that extends from the annular disk 41 and has been plastically deformed after the insertion of the cover 20 into the closing mechanism 40 to be partially inserted into the lateral groove portions 24 of the central shoulder 22 of the cover. In this case, the retaining elements 50 may be, for example, tabs extending from the edge of the annular disc 41 that delimits the second insertion passage 45.

Fig. 7 shows an embodiment similar to that described above, but in which the retaining element 50 is a plastic deformation of a part of the tubular skirt 42 located below the annular wall 21 of the cover 20, the container 10 being in vertical position.

This plastic deformation that forms the retaining element 50 determines a protrusion of the tubular skirt 42 into the first insertion passage 44, reducing the free passage to a size smaller than the size of the annular wall 21 and therefore preventing the extraction of the cover 20 inside the closing mechanism 40.

25

Other proposed features are also proposed to ensure the joint rotation of the closing mechanism 40 with the cover 20 during screwing and unscrewing.

The rotation of the glass lid 20 facilitates the breakage of the seal, facilitating the entry of air into the container 10 in case there is a certain degree of vacuum inside the container.

In order to achieve this joint rotation of the closing mechanism 40 with the cover 20 it is proposed that the second insertion passage 45 has a non-circular shape, and that the central projection 22 of the front of the cover 20 have a size and shape complementary to the size and shape of the second insertion passage 45, allowing its mutual coupling and preventing its relative rotation.

In the example shown in Fig. 8 the second insertion passage 45 is hexagonal and the central shoulder 22 is in the form of a hexagonal base wall. Other polygonal shapes would also be acceptable achieving the same effect.

It is also considered that said effect can be achieved without the central projection 22 reproducing the geometry of the second insertion passage 45, that is to say that in the example of the second hexagonal insertion passage 45, the central projection could have, for example, a star shape of six points, or consist of six protuberances coinciding with the corners of the hexagon, that is to say that any shape contained in the shape of the second insertion passage 45, but occupying its areas furthest from the center of the cover will obtain that desired effect.

Another example of embodiment is that shown in Fig. 9, in which a second insertion passage 45 and a central projection 22 in the form of a circle severed on one side are shown.

According to another embodiment of the invention it is proposed that the desired effect be achieved by means of a crimp between the tubular skirt 42 and the annular wall 21, said crimping being achieved by means of a non-circular geometry.

In the embodiment shown in Figs. 10 and 11 it is proposed that the annular wall 21 has a plurality of grooves in its perimeter, and that the tubular skirt 42 also includes complementary grooves with those of the annular wall 21, its crimping being produced preventing a relative rotation between both elements.

Another proposed feature of the invention is the incorporation of at least one central passage 26 in the cover 20, formed by interruptions of the central shoulder 22 that will divide it into diametrically opposite portions located in halves other than the cover 20.

Each portion of the central shoulder 22 will have support planes 27 perpendicular to the front of the cover 20 facing the central passage 26, allowing the insertion of a lever arm, such as a knife, a cutlery handle or a stick, through the central passage 26 said lever arm resting on two support planes 27 of two diametrically opposed central shoulder portions 22, allowing a torque to be transmitted to the cover 20 through said lever arm.

This feature can help overcome the vacuum inside the container 10, facilitating the opening of the lid 20.

Said feature may be combined with the proposed coupling between the cover 20 and the closing mechanism 40 in the direction of rotation, as shown in Figs. 8, 9 and 10, so that the lever arm allows the lid to be rotated together 20 with the closing mechanism 40, for example to initiate the opening of the container, or it can be independent thereof allowing the vacuum inside the container 10 to be overcome by turning the lid 20 using the lever arm without this causing the rotation of the closing mechanism 40, which must be unscrewed manually.

In Fig. 11 another embodiment is shown in which the face of the obverse of the annular wall 21 consists of four radial protuberances 60 uniformly spaced from each other.

Each protuberance 60 is in the form of an elongated lump that crosses the width of the face of the annular wall 21 on which they are arranged, from the outer periphery to the inner periphery. Each protuberance 60 has a thickness equal to half the thickness of the sealing ring 30.

This protuberance 60 will be integrated into the sealing ring 30 when pressure is exerted on the cover 20 with the closing mechanism 40, achieving a tight seal.

However, when the pressure is released, each protuberance 60 will facilitate an entry point of air into the container during the opening process thereof, facilitating the rupture of the vacuum that could exist in its intreiror.

Although not shown in the figures, it is contemplated that said protuberances 60 are located in the mouth 11 or in one of the two annular faces of the sealing ring 30.

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.
