Description

Closing device for resealing a can and can with appropriate closure device

The invention relates to a closure device for resealing a can, in particular a beverage can according to the preamble of claim 1. Furthermore, the invention relates to a can, in particular a beverage can with a closure device according to the invention.

Beverage cans with a closure device according to the preamble of claim 1 are known from the prior art. The corresponding closure devices include an outer member disposed outside the beverage can and an inner member disposed within the beverage can with a can wall sandwiched between the outer member and the inner member. The inner element of the closure device according to the prior art comprises, on its side facing the can wall, a connecting device in the form of a threaded bore into which a threaded pin of the outer element rotatably engages. On the outer element, a projection is provided, by means of which the outer element opposite can be rotated over the inner member, so that the distance of the inner member and the outer member changes to each other, wherein the distance of the outer member to the can wall remains constant and only the distance of the inner member is variable to the can wall. The outer element and the inner element of the closure device according to the prior art are embedded in a can opening of the beverage can. In the closed state, when the inner element and the outer element have a minimum distance from one another, a surface of the inner element facing the wall of the can closes a drinking opening provided in the outer element. By rotating the outer member, the distance of the inner member to the outer member increases, so that the drinking opening of the outer member is no longer sealed by the can wall facing surface of the inner member, so that a liquid located in the can can escape through the drinking opening of the outer member. A corresponding closure device according to the prior art has the disadvantage that after opening the closure device and subsequent drinking from the corresponding beverage can, in a dead space between the inner member and the outer member remains a part of the liquid or the drink, which is unhygienic for a and to the other unwanted pollution can result. A further disadvantage of the corresponding closure device is that, when drinking from a beverage can provided with this closure device, the mouth of the drinking person comes into direct contact with the outer element of the closure device. However, the exterior element may be dirty so that the person drinking can pick up the dirt. Furthermore, there is lig, that the closure device according to the prior art does not have a free drinking opening through which, for example, a straw can be inserted from outside the beverage can in the drink or in the liquid inside the can.

Furthermore, US 5,443,175 A discloses a closure device for reclosing a can. The closure device comprises a plastic insert disposed about a pouring aperture provided in the top bottom of the can. The pouring opening always remains open and is not closed by the plastic insert. On an inner periphery of the plastic insert gripping hooks are provided. Furthermore, the closure device comprises a closure element which is connected to a plug element. The plug element is arranged below the closure element. On an outer peripheral surface of the plug element gripping hooks are arranged, which are provided for cooperation with the arranged on the inner peripheral surface of the plastic insert gripping hook.

The object of the present invention is to provide an improved resealable closure device which reliably prevents leakage of the liquid from the can, as well as a can provided with a closure device according to the invention.

The object is achieved according to the invention specified in the claims 1, 12 and 13 features. Advantageous embodiments of the invention are specified in the subclaims.

According to the invention, an outer element is connected between a concrete arranged actuating device and an inner element, wherein the actuating device is movably connected to the inner element, so that the outer element via the actuating means indirectly connected to the inner element is connected in a distance-variable manner. The outer element and the inner element form a closure device.

The actuator may be, for example, a lever or a screw device, such as a screw knob. The connecting device may for example be an extension which is preferably arranged perpendicular to the inner element on the side of the inner element facing the can wall. Also, the connecting device may be, for example, a threaded pin.

According to the invention, the. Actuator occupy a closed position and an open position. In the closed position, the inner element to the outer member at a first distance, and in the open position, the inner member to the outer member has a second distance which is greater than the first distance. According to the invention, the inner element is in the closed position positive and / or non-positively on the inner surface of the socket wall, and the outer element is in the closed position positive and / or non-positively on the outer surface of the socket wall. Consequently, the can wall is clamped or clamped by the inner element and outer element. As a result, at least the inner element forms a circumferential seal around the can opening, so that no liquid can pass out of the can in the closed position of the actuating device. Furthermore, due to the positive and / or non-positive engagement of the inner element and the outer element on the wall of the can, the closure device can not or only be moved over a large effort against the can wall.

On the other hand, according to the invention in the open position, the inner member and / or the outer member to the inner surface or the outer surface of the socket wall such a distance that the closure device against the can wall is displaceable and / or pivotable, whereby the can opening by moving and / or pivoting the Closure device is accessible from the outside.

In the closed position, the can opening is therefore preferably closed by the closure device, so that no liquid can escape from the can opening. In the open position, however, the closure device can be moved so that the can opening is no longer closed by the closure device. Due to the second distance between the inner element and the outer element, which is greater than the first distance, the can wall is no longer clamped by the inner element and outer element, so that the closure device can be moved relative to the can.

The closure device according to the invention is hygienic, since the lips of a drinking person do not touch the outer element of the closure device itself, but as before, only enclose or touch the can opening of the can. The increased hygiene also contributes to the fact that there is no dead space between the outer element and the inner element in which a liquid, for example, which has come into contact with the mouth of a user, remains. The closure device according to the invention further offers the advantage that, as usual, for example Through the can opening straw can be inserted into the inside of the can through which a user of the can can drink a drink located in the can. In addition, the closure device of the invention is intuitive, as the actuator, ie, the He ^¬ bel or the screw knob is intuitively umlegbar or rotatable. Consequently, an operation of the closure device according to the invention for the user is facilitated. Preferably, the outer element further comprises a connection receptacle which is designed to receive the connection device of the inner element. The connecting device of the inner element preferably projects through the connection receptacle of the outer element. The connection receiving means may be, for example, an opening provided in the outer member.

Preferably, the inner element further comprises on its side facing the can wall a fixing device which engages positively or non-positively in the closed position of the actuating device in the can wall. The fixing device thus fixes the inner element to the can in a closed position in which the closure device can not be displaced relative to the can.

As a result of the fixing device, an increased safety of the closure device according to the invention is achieved since the fixation device considerably impedes or prevents a displacement of the closure device. Thus it can be prevented that unwanted liquid leaking from the can.

Preferably, the outer member further comprises on its the can wall or the can end face facing a first guide means adapted to guide and / or hold the outer member on the outer surface of the can wall, so that the underside of the outer member contacts the outer surface of the can wall.

The first guide device according to the invention ensures contact between the outer element and the can wall, so that only the inner element is at a distance from the can wall in the open position of the actuating device. Furthermore, it can be ensured by the first guide device that the outer element and thus the entire closure device is displaceable / pivotable only in a predetermined and defined direction relative to the can.

The first guide device may for example have the form of elongated snap hooks. Preferably, the inner element further comprises a sealing device surrounding the can opening, which bears against the inner surface of the can wall in the closed position.

The sealing device counteracts penetration of liquid into the space between the inner element and the wall of the can when the inner element resting against the wall of the can. Preferably, the sealing device is arranged in the edge region of the inner element, but at least so that the sealing device surrounds the can opening. The sealing device may for example be a sealing ring made of an elastic material, which is arranged for example in a sealing groove in the inner element.

Preferably, the outer element further comprises a Sealing device which bears against the outer surface of the can wall, at least in the closed position. However, the sealing device of the outer element can also rest in the open position of the actuating device on the outer surface of the can wall.

In a preferred embodiment, the connecting device is an extension extending obliquely and preferably perpendicularly from the side of the inner element facing the wall of the can, on whose region remote from the inner element a holding device is provided. In this preferred embodiment, the actuating device is a lever on which a support shaft is provided. The support shaft is connected to the holding device so that the lever is rotatably connected to the inner member via its extension. Thus, the lever is rotatable and / or tiltable relative to the inner element and relative to the outer element. Furthermore, the lever has an eccentric shape, so that by rotation and / or tilting of the lever about the support shaft, the distance of the support shaft to the can wall and thus the distance between the inner member and the outer member is variable.

The support shaft of the lever can be realized in the form of a bore through the lever, wherein the support shaft can then be connected to the holding device of the extension, for example via a pin made of plastic or metal. Alternatively, the support shaft can be arranged in the form of one or two pins on the lever, wherein these pins, which are arranged along the support axis, can engage in the holding device of the extension. In this case, the holding device of the extension would be one or two recesses or a passageway. bore through the extension.

By rotating or tilting the lever about the support shaft, the distance of the support shaft from the eccentric shape of the lever to the can wall and the support surface on the outer element changes because the lever is supported on an outer surface of the outer element. Since the extension of the inner member is connected to the support shaft, by turning or tilting of the lever, the distance of the inner member to the wall of the can depends. Thus, the distance of the inner member to the outer member of the Drehbzw. Tilting position of the lever dependent. The lever can be brought into a closed position in which the inner element to the outer member has a first and preferably minimum distance, and the lever can be brought into an open position in which the inner member to the outer member has a second distance which is greater than that first distance is. The lever may be designed so that for the transfer of the lever from the closed position to the open position, a rotation or tilting of the lever about the support shaft by 180 ° is necessary. Alternatively, however, the lever can also be configured such that, for the purpose of transferring the lever from the closed position to the open position, the lever is only to be rotated or tilted by an angle of 90 °, so that the entire closure device can be rotated by 90.degree tilted lever relative to the box can be moved and / or pivoted. This embodiment is particularly advantageous in that the lever simultaneously assumes a displacement function and / or pivoting function of the closure device. For clamping the can wall by the inner element and the outer element then has to be turned or tilted again in the opposite direction.

Alternatively, the lever may also be configured such that, for the purpose of transferring the lever from the closed position into the open position, the lever is to be tilted through an angle of 90 °, wherein the lever is tilted further by 90 ° into the same rotational or tilting direction the lever is brought into the closed position, wherein the can wall is braced by the inner member and the outer member. A corresponding embodiment of the closure device thus has two closed positions and an open position. In a preferred embodiment, the connecting device is an extension extending obliquely and preferably perpendicularly from the side of the inner element facing the wall of the can, on the region of which the inner element is remote a holding device is provided. In this preferred embodiment, the actuating device is a lever on which a support shaft and an eccentrically arranged rotation axis is provided. The support shaft thus extends parallel to the axis of rotation, and the support shaft has an offset to the axis of rotation. The support axis of the lever is rotatably connected to the holding device of the extension, so that the lever is movably connected to the inner element via its extension. Furthermore, the rotation axis of the lever is rotatably connected to the outer member, so that the lever is rotatable about the rotation axis in the outer member. By turning the lever, the distance between the inner member and the outer member is changeable. The axis of rotation and the support axis of the lever can be in the form of pins or projections on the lever, for example. Also, the axis of rotation and the support shaft can be realized by depressions in the lever. The holding device can accordingly have the form of an engagement and / or a recess or the shape of a projection in the form of a pin.

By rotating the lever can rotate due to the eccentric arrangement of the support shaft to the axis of rotation of the support shaft about the axis of rotation, so that the distance of the inner member to the outer member of the rotational position of the lever depends. The lever can thus be brought into a closed position in which the inner member to the outer member has a first and preferably minimum distance, and the lever can be brought into an open position in which the inner member to the outer member has a second distance which is greater than the first Distance is.

Preferably, the outer element further comprises on its side facing away from the can wall, a second guide means which runs parallel to the can wall. In this case, the axis of rotation interacts with the second guide device, preferably by meshing, so that the axis of rotation of the lever is movable in a direction parallel to the can wall relative to the outer element.

The second guide device may, for example, have the shape of a guide groove. The second guide device serves to enable a movement component of the rotational movement of the axis of rotation that runs parallel to the can wall, and that a movement component perpendicular to the can wall is provided. wall extending motion component of the rotational movement of the axis of rotation is prevented, so that only a perpendicular to the can wall extending component of movement of the support shaft is transmitted to the extension and thus to the inner member.

In a further preferred embodiment, the connecting device is a threaded pin extending obliquely and preferably perpendicularly from the side of the inner element facing the wall of the can. The actuating device is a screw device, preferably a screw knob, which / on the side of the can wall associated with a recess having an internal thread, in particular a threaded bore, wherein the threaded bore is formed for receiving the threaded pin. The screw is rotatably connected via the threaded bore with the threaded pin of the inner member, so that by turning the screw the distance between the inner member and the outer member is variable.

The screwing device can consequently assume a closed position in which the inner element to the outer element has a first and preferably minimum distance which corresponds to the wall thickness of the can wall, and the screwing direction can assume an open position in which the outer element has a second distance to the inner element, which is larger than the first distance.

By pressing or turning the screw thus the distance of the inner member of the can wall can be easily changed. The opening or closing of the closure device according to the invention is thus intuitive for the user. In a further preferred embodiment, the outer element further comprises a holding device, by means of which the outer element is held on the can wall. The outer element can be rotated and / or pivoted relative to the can wall about the holding device.

By a corresponding holding device, it is possible that the outer element does not necessarily have to include the fixing device described above, because the outer element is held by the holding device on the can wall. The holding device can be designed, for example, in the form of a recess or a through-hole in the outer element.

The material of which the closure device is made is preferably a plastic. However, the present invention is not limited thereto. Thus, the closure device or at least individual components, for example, from a metal or a metal sheet of aluminum, iron or steel. Thus, the support shaft and / or the axis of rotation may consist of a metal, or a pin inserted through the support shaft and / or axis of rotation may be formed from a metal.

The closure device according to the invention can be used for a can, in particular a beverage can with a can wall in which a can opening is provided. The can according to the invention then comprises one of the closure devices described above, and the connecting device of the outer element protrudes through the can opening.

In a further preferred embodiment, the can further comprises a connection opening through which the connection Training device protrudes.

The connection opening may be straight and elongate, so that the closure device can be displaced with respect to the wall of the can. However, the connecting opening can also be configured in the shape of an arc in the shape of an arc or a circle, so that the closure device can be pivoted about a bearing device of the can wall as the center of this arcuate or circular-segment-shaped movement.

In a further preferred embodiment, the can wall further comprises an outer element guide device which is designed to guide on displacement of the outer element and this on the can wall.

A corresponding configuration of the can wall of the can offers the advantage that the outer element of the closure device does not necessarily have to have the above-described first guide device in order to be displaceable and / or pivotable in a defined manner relative to the can wall. Furthermore, the outer element guide device can be used to ensure that the outer element of the closure device is always in contact with the can wall of the can.

Preferably, the can wall of the box according to the invention further comprises a Fixiereinrichtungsaufnähme, which is formed to receive the fixing device with an exposed can opening and located in the closed position actuator, so that the outer member and the inner member aligned parallel to each other are.

This Fixiereinrichtungsaufnähme can be configured for example in the form of a protuberance of the can wall, in which the fixing device is receivable. Without a corresponding Fixiereinrichtungsaufnähme the inner element would no longer be aligned parallel to the can wall with exposed can opening and located in the closed position actuator, the inner element. Consequently, the inner element would no longer be configured parallel to the outer element of the closure device. Consequently, the fixation device receptacle offers the advantage that when the can opening is uncovered when the actuating device is in the closed position, the outer element and the inner element are aligned parallel to one another.

The invention will be explained in more detail with reference to drawings. In detail:

Hereinafter, a first embodiment of the closure device 100a, 100b, 100c for reclosing a can 1 according to the present invention will be described with reference to FIGS. It can be seen from Figures 1, 2, 3, 5, 6, and 7 that the can wall 2 of a can 1 is sandwiched between an inner member 110 and an outer member 120a, 120b, 120c of the closure device 100a, 100b, 100c , The inner element 110 comprises on its side facing the can wall 2 a connecting device 111. The connecting device 111 is an extension 111 extending perpendicularly from the side of the inner element 110 facing the can wall 2. A holding device is provided on the region of the extension 111 remote from the inner element 110 114 provided. From FIG. 4 it can be seen that the holding device 114 has the shape of a depression 114 or a through-bore 114. It can also be seen from FIG. 8 that the holding device 114 can have the shape of a depression 114.

Referring to Figures 1 to 4, the first embodiment of the closure device 100a will be described. The closure device 100a comprises an actuating device 130a in the form of a lever 130a, which is arranged outside the can 1. The lever 130 a is provided with a support shaft 132. This support shaft 132 may be configured differently. Thus, the support axle 132 For example, have the form of a through hole through the lever 130a. Alternatively, the support shaft 132 may be in the form of recesses in the lever 130a. Furthermore, it is also possible that the support shaft 132 is realized in the form of outstanding from the lever 130 a pins.

The support shaft 132 is connected to the holding device 114 of the inner element 110 via a pin, not shown, wherein the pin can be formed of different materials, such as plastic or metal. The pin, not shown, projects through the support shaft 132 and through the holding device 114 of the inner element 110, so that the lever 130a is rotatably and movably connected to the extension 111 of the inner element 110. The length of the pin, not shown, preferably corresponds to the width or the extent of the lever 130a, so that the pin, not shown, does not protrude beyond the lever 130a, when the pin is inserted through the support shaft 132 and the holding device 114. Alternatively, however, the pin may also have a greater length than the corresponding extent of the lever 130a. In this case, the pin, not shown, may also be received in the outer member 120a via correspondingly arranged bores or depressions (not shown). The outer member 120a may, in a corresponding embodiment, either a recess or through hole in an edge, in which the pin, not shown, is received, or alternatively may have on both flanks depressions or through holes into which the pin, not shown, is received.

The outer member 120a is thus between the lever 130a and the inner member 110, wherein the lever 130a is rotatably connected to the extension 111. Therefore, the inner member 110 is indirectly connected to the outer member 120a via the lever 130a distance variable.

From Figure 1 it can be seen that the lever 130a can assume a closed position S, which is indicated in Figure 1 with a lever 130a directed to the right or folded. The lever 130a can be brought to the left about the support shaft 132 in an open position shown in Figures 2 and 3 0.

In the closed position S of the lever 130a, the inner member 110 has a first distance to the outer member 120a corresponding to the thickness of the can wall 2 sandwiched therebetween. In this closed position S, the inner element 110 and the outer element 120a are clamped to the can wall 2 therebetween, wherein in this closed position S at least the can opening 3 is sealed by a fitting on the inside of the can wall 2 and the can opening 3 encircling part of the inner member 110 , That is, both the inner member 110 and the outer member 120a are in direct contact with the can wall 2. In the open position 0 of the lever 130a, the inner member 110 has a second distance to the outer member 120a which is greater than the first distance. In the open position 0, the inner element 110 moves away from the can wall 2, releasing the can opening 3.

The lever 130a has an eccentric shape. In FIGS. 1 to 4, the lever 130a is supported at a point of the eccentric formed or at a point of the eccentric form on the outer member 120a. By turning or tilting the lever 130a, the eccentric formed by the eccentric shape of the lever 130a is rotated, so that the rotational movement of the lever 130a is converted into a lifting movement of the support shaft 132. Due to the connection between the support shaft 132 and the inner element 110 via its extension 111, the lifting movement of the holding axis 132 is transmitted to the inner element 110 by a rotational movement of the lever 130a, so that the distance of the inner element 110 by turning or tilting the lever 130a Can wall 2 can be changed. On the side of the outer element 120a facing the can wall 2, the outer element 120a is held in contact with the can wall 2 so that upon rotation or folding over of the first guide device 22 to be described later in FIGS. 9a and 9b Levers 130a of the closed position S in the open position 0, only the distance of the inner member 110 to the can wall 2 changed.

Due to the spacing of the inner element 110 from the can wall 2, the can wall 2 is no longer braced by the outer element 120a and the inner element 110. Therefore, it is possible to move the entire closure device 100a relative to the can wall 2 of the can 1. The displacement of the closure device 100a is effected by a displacement of the outer element 120a or by a displacement of the lever 130a and is also transmitted to the inner element 110 due to the indirect connection of the outer element 120a with the inner element 110. FIG. 3 shows a closure device 100a displaced with respect to the can wall 2. By moving the closure device 100a, the can opening 3 of the Can 1 released.

In the state shown in FIG. 3, in which the can opening 3 of the can 1 is released by the closure device 100a, the closure device 100a can again be brought into a clamping position by moving the lever 130a from the open position 0 to the closed position S itself , so that the inner member 110 rests against the can wall 2 again. By a corresponding turning or folding of the lever 130a into the closed position S, the entire closure device 100a is again brought over the can opening 3 due to gravity during a drinking process out of the can, in which the can 1 is usually tilted becomes. After completion of the drinking process, the user can bring the lever 130a from the closed position S back to the open position O, and then the user can push the entire closure device 100a again on the can opening 3 and then the lever 130a from the open position 0 back to the closed position S. bring, so that the can opening 3 of the can 1 is closed again.

It can be seen from FIGS. 1 to 3 that the inner element 110 comprises, on its side facing the can wall 2, a sealing device 13 which, in the closed position S, bears against the inner surface of the can wall 2. The sealing device 13 is preferably arranged in the edge region of the inner element 110 and may for example consist of an elastic material which is arranged in a sealing groove in the inner element 110. The sealing groove 13 acts to prevent liquid from entering the space between the inner element 110 and the can wall 2 in the closed position S. the lever 130 against.

It can be seen from FIG. 4 that the outer element 120a has a connecting receptacle 21 designed to receive the extension 111 in the form of an opening 120, wherein the extension 111 of the inner element 110 projects through the connection receptacle 21. The size of the connection receptacle 21 is preferably such that the extension 111 is in contact with the connection receptacle 21 in an assembled state, so that a displacement force transmitted to the lever 130a or to the outer element 120a is transferred to the inner element 110.

Furthermore, it can be seen from FIGS. 1 to 4 that the inner element 110 comprises, on its side facing the can wall 2, a fixing device 12 in the form of a projection 12. This projection 12 engages in the closed position S of the lever 130 a positive and / or non-positively in the socket wall 2, so that in addition to the by the inner member 110 and outer member 120 a to move the Verschlussvorichtung 100 a counteracting clamping force, the fixing device 12 of the inner member 110 to move the Closing device 100a counteracts because the fixing device 12 fixes the inner member 110 to the can 1 in a closed position. In this closed position, the closure device 100a can not be moved relative to the can 1.

FIG. 12 shows the plan view of a can wall 2 of a can 1, in this case the plan view of the can end 2 of a can 1. The can wall 2 has a can opening 3, which in this case is a beverage opening 3. Furthermore, the can wall 2 has a connection opening 4, through which the connection device 111 protrudes, so that the inner element 110 is connected to the outer element 120a. can be tied.

In FIG. 4, the can opening 3 and the connection opening 4 between the inner element 110 and the outer element 120a are indicated. The fixing device 12 pushes in the closed position S of the lever 130 in the can opening 3, so that in the closed position S, the fixing device 12 is tilted relative to the can wall 2. The elongate extent of the connecting opening 4 is greater than the corresponding elongate extent of the connecting device or of the extension III, so that in the open position 0 of the lever 130a, the extension 111 or the connecting device 111 can be moved in the connection opening 4.

FIGS. 5 and 6 show a first alternative of the closure device 100b according to the first embodiment. Components and features which are provided with the same reference numerals have the same shape or the same functionality as the assemblies or features already described, so that a repetition is avoided. The closure device 100b differs from the closure device 100a in that the actuating device 130b has a different shape than the actuating device 130a. Furthermore, the outer element 120b has a shape adapted to the lever 130b.

The lever 130b has such an eccentric shape that the lever 130b is transferred from the closed position S shown in FIG. 5 to the open position 0 shown in FIG. 6 by turning or tilting about the support shaft 132 can be, with the lever 130b is only about 90 ° to turn or tilt. In the open position 0 of the lever 130b, the lever 130b therefore protrudes as shown in Figure 6 from the outer member 120b. In the open position 0 shown in Figure 6, the distance of the support shaft 132 to the can wall 2 is smaller than the distance of the support shaft 132 to the can wall 2 in the closed position S.

Due to the lever 130b protruding vertically from the can wall 2, a user of a can 1 provided with the closure device 100b can move the closure device 100b very easily by means of the lever 130b, so that the can opening 3 of the can 1 is released by displacing the closure device 100b.

In the first alternative of the first embodiment of the closure device 100b shown in FIGS. 5 and 6, the support shaft 132 is arranged in or on the lever 130b at the edge in such a way that the lever 130b has only one closed position S, in which the lever, such as shown in Figure 5, oriented to the right in the outer member 120 b is arranged. Alternatively, it is also possible to arrange the support shaft 132 in the lever 130b such that the lever 130b has two closed positions S and one open position 0. For this purpose, the support shaft 132 must move downwards in the embodiment shown in Figure 5, so that the support shaft 132 to the bottom and to the top of the lever 130b is equally spaced, said distance of the support shaft 132 to the bottom and to the top of the lever 130 b must be greater than the distance of the support shaft 132 to the front side of the lever 130 b. The front side of the lever 130b is supported in the open position 0 of the lever 130b on the outer member 120b.

With a corresponding configuration of the lever 130b it is possible to bring the lever from the closed position S in the open position O by turning the lever 130b by 90 °, to displace the entire closure device 100b by means of the lever 130b projecting perpendicularly from the can wall 2, and then to move the lever 130b by means of another Rotation again by 90 ° in the same direction to bring in a further closed position S, in which the inner member 110 rests against the can wall 2 again, so that the closure device 100b can not be moved relative to the can wall 2. A corresponding embodiment of the lever 130b offers the advantage that a movement which is particularly flowing for the user is made possible in order to open or close the can, since the lever 130b is only to be turned or tilted in one direction to open, move and close the closure device.

FIGS. 7 and 8 show a second alternative of the first embodiment of the closure device 100c according to the first embodiment of the invention. Again, the actuator 130c is formed in the form of a lever 130c, which is disposed outside the can 1. The lever 130c comprises the support shaft 132 and an axis of rotation 133 arranged eccentrically therefrom. The support shaft 132 thus runs parallel to the axis of rotation 133, the axis of rotation 133 being at a distance from the support shaft 132. From Figure 8 it can be seen that the support shaft 132 has the shape of protruding pins 132 in a recess of the lever 130c. Furthermore, it can be seen from FIG. 8 that the rotation axis 133 of the lever 130c also has the form of pivot pins 133 arranged on the outside of the lever 130c. The support pins 132 form the support shaft 132, and the two pivot pins 133 form the rotation axis 133. The support shaft 132 of the lever 130c is connected to the bearing-forming holding device 114 of the inner element 110, so that the lever 130c is rotatably connected to the inner element 110 via its extension 111.

The outer member 120c is thus disposed between the lever 130c and the inner member 110, the lever 130c being rotatably connected to the extension 111. Therefore, the inner member 110 is indirectly connected to the outer member 120c via the lever 130c in a distance-variable manner.

The rotation axis 133 of the lever 130c is rotatably connected to the outer member 120c. It can be seen from FIG. 8 that the outer element 120c on its side facing away from the can wall 2 comprises a second guide device 124 in the form of a guide groove 124 which runs parallel to the can wall 2. The rotation axis 133 of the lever 130c is engaged with this guide 124 of the outer member 120c, so that the rotation shaft 133 is movable in a direction parallel to the can wall 2 opposite to the outer member 120c.

From Figure 7 it can be seen that the lever 130c can assume a closed position S, which is indicated in Figure 7 with a lever 130c directed to the right or folded. The lever 130c can be brought to the left about the rotation axis 133 in an open position 0.

The change in the distance of the inner member 110 to the can wall 2 is achieved by rotatably connecting the rotation shaft 133 with the outer member 120c, so that the lever 130c is rotatable about the rotation shaft 133 in the outer member 120c. By rotating the lever 130c about the rotation axis 133, the support shaft 132 rotates about the rotation axis. axis 133. The rotational movement of the support shaft 132 about the axis of rotation 133 has both a horizontal, directed parallel to the can wall 2 movement component and a vertical and directed perpendicular to the can wall 2 movement component. The horizontal movement component of the support shaft 132 is absorbed by the second guide device 124 of the outer element 120c, so that only the vertical movement component of the support shaft 132 is transferred to the extension 111 of the inner element 110.

However, the outer member 120c need not necessarily comprise a second guide means 124. Namely, it is also possible that the rotation axis 133 of the lever 130c is connected to the outer member 120c so that a movement directed parallel to the can wall 2 is not compensated. This would lead to an increased force being necessary for shifting the lever 130c from the closed position S into the open position 0. After overcoming this breakaway torque, the closure device would function as described.

From FIG. 7 it can be seen that in the closed position S of the lever 130c, the support shaft 132 is arranged above the rotation axis 133, ie that the support shaft 132 has a greater distance from the can wall 2 than the rotation axis 133. By turning the lever 130c from the closed position S in the open position 0, the support shaft 132 rotates about the rotation axis 133, wherein in the end position of the lever 130c, the support shaft 132 is disposed below the rotation axis 133. That is, in the open position 0, the distance of the support shaft 132 to the can wall 2 is smaller than the distance of the rotation axis 133 to the can wall 2. This vertical stroke of the support shaft 132 is on the extension 111 and thus transferred to the inner member 110, whereby the inner member 110 away from the can wall 2.

FIG. 8 shows a detailed view of the lever 130c, which is connected to both the outer element 120 and the extension 111 of the inner element 110. In Figure 8, the lever 130c, the closed position S, since the distance of the support shaft 132 to the can wall 2 is greater than the distance of the rotation axis 133 to the can wall 2. From Figure 8 it is clear that the support shaft 132 with respect to the rotation axis 133 arranged eccentrically is. By rotating the lever 130c about the rotation axis 133, the distance of the support shaft 132 relative to the can wall 2 changes, so that due to the connection of the lever 130c on the support shaft 132 with the holding device 114 of the extension III and the distance of the inner member 110 to the can wall. 2 changed. As can be seen from FIG. 8, the extension 111 can have a recess in its center, whereby insertion of the support shaft 132 into the holding device 114 of the extension 111 is facilitated.

FIGS. 9 to 11 show a third alternative of the first embodiment of the closure device 100d of the invention. The operation of the closure device 100d shown in FIGS. 9 to 11 is very similar to that of the closure device 100c shown in FIGS. 7 and 8, so that reference is made to the preceding description. However, the shutter lOOd differs from the shutter 100c in that, for transferring the shutter lOOd from the open position to the closed position (and vice versa), the actuator 130c is tilted only by 90 °. Another difference between the closure device 100d and the closure device 100c is that the outer element 120d of the closure device 100d comprises a third guide device 125 in the form of a guide groove 125 on its side facing away from the can wall (2). The guide groove 125 extends perpendicularly to the can wall (2) and extends from an outer surface of the outer element 120d facing away from the can wall 2 to the second guide device 124 in the form of a guide groove 124, in which it opens. Thus, the second guide means 124 and third guide means 125 form an L-shaped groove in a perpendicular to the can wall (2) aligned material edge of a recess of the outer member 120d, wherein in the assembled state of the closure device lOOd the actuator 130c rotatable or tiltable in the recess is arranged.

When assembling the closure device 100d, the lever 130c is inserted from above into the recess of the outer element 120d, wherein the rotation axis 133, which is realized as laterally protruding from the lever 130c pins 133, is received by the third guide means 125. In the insertion movement of the lever 130c into the outer member 120d, the support shaft 132, which is realized as inwardly directed pins 132 in a recess of the lever 130c, abuts on the connecting means 111 projecting through the connection receiving means 111 of the inner member 110. Since the connecting means 111 of two elastic connecting webs 111, which protrude through two connection openings 4 of the can wall 2, the connecting webs III are pressed against each other upon compression of the inner member 110 and the lever 130c, so that the rotation axis 132 engages in the formed as a holes 114 connecting means 114. If at the insertion movement of the lever 130c into the outer member 120d, the pins 132 of the lever 130c are engaged in the holes 114 of the connecting webs 111, then the pins 133 of the lever 130c are in the connecting portion of the guide grooves 124 and 125, as shown in FIG. When assembled, pulling out the lever 130c from the outer member 120d is prevented because the outer member 120d is disposed between the lever 130c and the inner member 110, and the rotational axis 132 of the lever 130c is connected to the retainer 114 of the connector 111 of the inner member 110.

FIG. 10 shows the closure device 100d, whose lever 130c is in the closed position S, in which the inner element 110 rests against the inner side of the can wall 2 and closes the can opening 3. FIG. 11 shows the closure device 10000d shown in FIG. 10, wherein the lever 130c is in the open position O, which is achieved by turning or tilting the lever 130c about the rotation axis 133. By rotating the lever 130c about the rotation axis 133, the support shaft 132 rotates about the rotation axis 133. The rotation of the support shaft 132 about the rotation axis 133 has both a horizontal movement component directed parallel to the can wall 2 and a vertical movement component perpendicular to the can wall 2 , As can be seen from FIG. 11, the horizontal movement component of the support shaft 132 is absorbed by the second guide device 124 of the outer element 120d, so that only the vertical movement component of the support shaft 132 is transferred to the extension 111 of the inner element 110, whereby the distance between the inner element 110 and the inner element 110 Inner surface of the can wall 2 is increased.

The inner element 110 of the closure device lOOd um- further includes an inner element vent opening 115 around which a vent opening seal 14 is arranged in the form of a sealing ring 14 formed of an elastically deformable material. It can be seen from FIG. 10 that in the closed position S of the lever 130c, the sealing ring 14 rests against the inner surface of the can wall 2, so that no liquid located in the can 1 can escape to the outside via the inner element ventilation opening 115.

For example, if a carbonated liquid is in the can interior, then the gas pressure within the can 1 is usually greater than the air pressure surrounding the can 1, such that the inner member 110 of the closure device 100d is pressed against the inner surface of the can wall 2. The inner element vent opening 115 in this case facilitates an equalization of the gas pressure within the can 1 with the air pressure surrounding the can 1 when the lever 130c is moved to the open position 0 (FIG. 11). Thus, for example, the outer element 120d may be held on the outer surface of the can wall 2 by means of a first guide device 22 shown in FIGS. 12a and 12b, such that only the inner element 110 disengages from the inner surface of the can wall 2 by displacing the lever 130c.

When the closure device 100d is moved in order to expose the can opening 3, the inner element ventilation opening 115 can be pushed over a ventilation opening 9 provided in the can wall 2. In this position, when the lever 130c is returned to the closed position S, the inner member 110 and the outer member 120d clamp the can wall 2, and the vent opening seal 14 then clamps the vent 9 of FIG Can wall 2 seals. If in this position a person drinks from the can 1 and thereby seals the can opening 3 with his lips, arises within the can 1, a suppression. This negative pressure is compensated by the fact that air from outside the can 1 flows into the can 1 via the inner element ventilation opening 115 and the ventilation opening 9 in the can wall 2.

It can be seen from FIGS. 9 to 11 that the inner element ventilation opening 115 is arranged between the connecting webs 111 and the ventilation opening 9 between the connecting openings 4. Alternatively, the inner element ventilation opening 115 and the ventilation opening 9 in the can wall 2 can also be arranged at other positions as long as they can be aligned with one another. Thus, the ventilation opening 9 could also be arranged next to the connection opening 4 and the inner element ventilation opening 115 corresponding to the connection device 115.

It can be seen from FIGS. 12a and 12b that the outer element 120a, 120b, 120c, 120d comprises a first guide device 22 on its side facing the can wall 2. The first guide means 22 is adapted to guide and / or hold the outer member 120a, 120b, 120c, 120d on the outer surface of the can wall 2 so that the underside of the outer member 120a, 120b, 120c, 120d contacts the outer surface of the can wall 2 , From Figures 12a and 12b it can be seen that the first guide means 22 in the form of elongated snap hooks 22 which engage in the connection opening 4 of the socket wall 2. The elongated snap hooks 22 allow the outer element 120a, 120b, 120c, 120d to be displaced along the elongated alignment of the snap-in latch. By the first guide means 22, the outer member 120a, 120b, 120c, 120d remains in contact with the can wall 2, so that in the open position O of the lever 130a, 130b, 130c, only the inner member 110 is removed from the can wall 2.

FIGS. 13 and 14 show a top view of a closure device 100a, 100b, 100c, 100d according to the first embodiment of the present invention. FIG. 13 shows the corresponding closure device, in which the lever 130a, 130b, 130c is in the closed position S, whereas FIG. 14 shows the closure device 100a, 100b, 100c, 100d according to the invention, in which the lever 130a, 130b, 130c in the open position O located. It can be seen from FIG. 13 that the closure device 100a, 100b, 100c, 100d closes the can opening 3. In the closed position S of the lever 130a, 130b, 130c, the inner member 110 and the outer member 120a, 120b, 120c, 120d form and / or non-positively on the inner surface or outer surface of the socket wall 2, so that the inner member 110 is a circumferential seal of Can opening 3 forms, and so that the closure device 100a, 100b, 100c, lOOd with respect to the can 1 can not be moved. It can be seen from FIG. 13 that the closure device 100a, 100b, 100c, 100d furthermore has at least one securing tab 131 which is arranged between the lever 130a, 130b, 130c and the outer element 120a, 120b, 120c, 120d. The securing tab 131 can, for example, have the form of a thin plastic connection 131 between the lever 130a, 130b, 130c and the outer element 120a, 120b, 120c, 120d. By turning or turning the lever 130a, 130b, 130c, the securing tabs 131 are broken, so that intact and unbroken securing tabs 131 are an indication that the closure device 100a, 100b, 100c, 100d has not yet been opened. This is particularly advantageous in that intact securing tabs 131 can ensure that no unwanted substances or materials have been introduced into the can 1 by foreign persons.

In the open position O of the lever 130a, 130b, 130c shown in FIG. 14, the inner element 110 is spaced from the can wall 2 such that the can wall 2 is no longer clamped by the inner element 110 and the outer element 120a, 120b, 120c, 120d, and so that the fixing device 12 no longer engages in the can opening 3, or a recess between the fixing device 12 and the extension 111 does not engage in a web of material 5 of the can wall 2 between the can opening 3 and the connection opening 4. Due to the spacing of the inner element 110 from the can wall 2, the user can move the outer element 120a, 120b, 120c, 120d and thus the entire closure device 100a, 100b, 100c, 100d with respect to the can 1 so that the can opening 3 is exposed by the displacement becomes. From the exposed can opening 3, for example, the user can drink the beverage contained therein or, through the free-standing can opening 3, insert a straw into the liquid in the can and drink the liquid by means of the straw. After the user has drunk from the can, the user can push the closure device 100a, 100b, 100c, 100d back over the can opening 3 and bring the lever 130a, 130b, 130c from the open position 0 to the closed position S, so that the Inner element 110 rests against the can wall 2 again, whereby a clamping of the can wall 2 by the inner member 110 and the Außeneleraent 120a, 120b, 120c, 120d is reached. Also, by moving the lever 130a, 130b, 130c from the open position 0 into the closed position S, the fixing device 12 shifts into the can opening 3, so that the inner element 110 can no longer be displaced relative to the can wall 2 and thus opposite the can 1 , Owing to the connection of the inner element 110 to the outer element 120a, 120b, 120c, 120d via the actuating device 130a, 130b, 130c or via the lever 130a, 130b, 130c, the outer element 120a, 120b, 120c, 120d can also be in the closed position S of the lever 130a, 130b, 130c are no longer verscho ^¬ ben against the can 1.

The distance, or the distance, by which the closure device 100a, 100b, 100c, 100d can be displaced with respect to the can wall 2 can be limited by the length of the connection opening 4 and / or can be determined by the size of the outer element 120a, 120b , 120c be limited when the outer member 120a, 120b, 120c against, for example, a projection of the can 1 strikes.

FIG. 15 shows a plan view of the outer element 120a, 120b, 120c, 120d with levers 130a, 130b, 130c arranged therein. FIG. 16 shows the lever 130a, 130b, 130c shown in FIG. 15 in a perspective view. The lever 130a, 130b, 130c comprises a securing device 135 in the form of a tab 135, which is connected to the side facing away from the can wall 2 of the lever 130a, 130b, 130c with this. The tab 135 extends beyond the lever 130a, 130b, 130c out to the outer member 120a, 120b, 120c, 120d, on which the tab 135 rests.

Between the tab 135 and the lever 130a, 130b, 130c predetermined breaking lines 136 are provided in the form of two perforation lines 136. When the lever 130a, 130b, 130c is first moved from the closed position S to the open position O, the connection between the tab 135 and the lever 130a, 130b, 130c breaks at the predetermined breaking lines 136, since the tab 135 on the outer element 120a, 120b , 120c, 120d rests.

Thus, intact and unbroken fracture lines 136 are an indicator that the closure device 100a, 100b, 100c, 100d has not yet been opened.

In Figures 1 to 16, the closure device 100a, 100b, 100c, lood is shown so that the support shaft 132 and, optionally, the rotational axis 133 of the lever 130a, 130b, 130c perpendicular to the ^■ * the displacement direction of the closure device 100a, 100b, 100c, lood and the elongate extent of the connection opening 4 extends, so that the tilting direction of the lever 130a, 130b, 130c runs parallel to the displacement direction. However, the support shaft 132 and optionally the rotation axis 133 of the lever 130a, 130b, 130c can also be arranged at any angle and thus also parallel to the direction of displacement of the closure device 100a, 100b, 100c, 100d, so that, for example, the lever is perpendicular to the direction of displacement of the Closure device 100a, 100b, 100c, lOOd is tilted.

A second embodiment of the closure device 200a, 200b according to the present invention will be described below with reference to FIGS. 18 to 21. Here, the same reference numerals designate the same components or features, so that their description to avoid repetition is omitted. FIG. 18 shows a schematic axial cross section through a closure device 200a according to the second embodiment of the present invention. The can wall 2 is sandwiched between the inner member 210 and the outer member 220a. The connecting device 211 is a threaded pin 211 extending perpendicularly from the side of the inner element 210 facing the can wall 2. The actuating device 230a is a screwing device 230a or a screwing knob 230a which has an internally threaded recess on its side associated with the can wall 2, in particular has a threaded bore, wherein the threaded bore is formed for receiving the threaded pin 211. The screw 230a and the screw knob 230a is rotatably connected via the threaded bore with the threaded pin 211 of the inner member 210, so that by turning the screw 230a, the distance between the inner element 210 and the outer member 220a is changeable due to the thread pitch of the threaded pin and the threaded hole.

Due to the fixation of the outer element 220a by means of the first fixing device 22 on the can wall 2 shown in FIGS. 9a and 9b, only the distance of the inner element 210 from the can wall 2 is increased by turning the screw device 230a from the closed position S to the open position O.

FIG. 19 shows a plan view of the closure device shown in FIG. The closure device 200a is shown in FIG. 19 in the closed position S of the screw device 230a. The rotational movement of the screw 230a is indicated in Figure 19 by an arrow. Due to the indicated rotational movement of the screw device 230a about the threaded pin 211, the screw direction 230a in the open position 0, in which the closure device 200a can be moved relative to the can wall 2 and thus with respect to the can 1, whereby the can opening 3 is exposed. To close the closing device 200a, the outer element together with the screwing device 230a has to be slid over the can opening 3 again, and the screwing device 230a must again be rotated clockwise in the arrangement shown in FIG. 19, so that the screwing device 230a assumes the closed position S again , and the inner member 210 rests against the can wall 2. The remaining operation of the closure device 200a is identical to the closure device 100 according to the first embodiment of the present invention.

Figs. 20 and 21 show a modification of the shutter device 200b according to the second embodiment of the present invention. In the modification of the second embodiment, the screw 230b is formed so that, by turning the screw 230b about the screw 211 from the outside, the position of the screw 230b against the can wall 2 is not changed since the threaded hole is centrally located in the screw 230b. The screwing device 230b is partially embedded in the outer element 220b, wherein the outer element 220b is arranged between the screwing device 230b and the inner element 210. By turning the screw 230b, the distance of the inner member 210 relative to the can wall 2 is variable, so that depending on the position of the screw 230b, the closure device 200b is either displaceable (open position 0 der- screw 230b), or is not displaceable (closed position S of the screw 230b). The remaining mode of operation is identical to the closure device 200a described with reference to FIGS. 18 and 19.

In FIG. 17 it is shown that the can wall 2 comprises the can opening 3 and the connection opening 4. However, the can opening 3 may, for example, also be configured such that the connection device 111, 211 also protrudes through the can opening 3 in order to connect the inner element 110, 210 to the outer element 120a, 120b, 120c, 120d, 220a, 220b.

Hereinafter, a third embodiment of the shutter device according to the present invention including a modification will be described with reference to FIGS. 22 to 31. In the third embodiment of the present invention, the can wall 2 of the can 1 does not necessarily have to have a communication port 4. However, the third embodiment of the shutter device is not limited thereto. The third embodiment of the closure device according to the present invention can also be used with a can 1 which has both a can opening 3 and a connection opening 4.

FIG. 22 shows a schematic axial cross section through the closure device 100e according to the invention according to the third embodiment. In FIG. 22, only the outer element 120e of the closure device 100e is shown. FIG. 27 shows the inner element 110 of the closure device 100e.

The outer member 120e is on the can wall 2 by means of a bearing device 6 rotatably mounted. The outer element 120e has a holding device 23, not visible in FIG. 22, which is designed in the form of a through-bore or a depression 23 in the outer element 120e. The bearing device 6 of the can wall 2 is configured in the form of a protuberance 6 of the can wall 2, which protrudes through the through hole 23 of the outer member 120e. Consequently, there is a kind of rivet connection between the outer member 120d and the can wall 2. The outer member 120e is rotatably connected to the can wall 2 by means of the described rivet connection so that the outer member 120 can be pivoted by the bearing means 6. The inner element 110 illustrated in FIG. 27 differs, for example, from the inner element 110, which is illustrated in FIGS. 1 to 14, in that the fixing device 12 is arranged differently with respect to the connecting device 111. FIG. 23 schematically shows the positioning of the inner element 110 in relation to the can opening 3. When the can opening 3 is closed by the closure device 100e and the actuating device 130a, 130b, 130c is in the closed position S, then the fixing device 12 engages in the edge of the can opener - 3 tion, so that the inner member 110 with respect to the can opening 3 and consequently with respect to the can wall 2 can not be moved or pivoted. As a result of the connection of the outer element 120e to the inner element 110 via the connecting device or the extension 111, consequently, the outer element 120e of the closure device 100e can not be displaced or pivoted in relation to the can wall 2.

FIG. 24 shows a top view of the closure device. tion 100e, which closes the can opening 3 of the can 1. FIG. 25 shows a plan view of the same can 1 or the same can wall 2 as in FIG. 24, wherein the closure device 100e is pivoted relative to the can wall 2 about the bearing device 6, so that the can opening 3 of the can wall 2 is exposed. FIG. 26 shows a top view of the can wall 2 on which the closure device 100e shown in FIGS. 22, 24, 25, 27 is arranged.

The mode of operation by which the distance of the inner element 110 from the outer element 120e is changed by the actuating device or by the lever 130a, 130b, 130c is identical to the functioning of the closure device 100a, 100b, 100c, 100d, as with reference to the figures 1 to 16, so a description will be omitted. In FIG. 24, the outer element 120e of the closure device 100e closes this can opening 3 of the can wall 2. The outer element 120e of the closure device 100e is rotatably mounted on the can wall 2 by means of the bearing device 6 of the can wall 2. As a result, the distance of the outer member 120e from the can wall 2 is not changeable. Between the actuator or the lever 130a, 130b, 130c and the outer member 120e two locking tabs 131 are arranged. With respect to the operation of the securing tabs 131, reference is made to the description with reference to FIG. The outer element 120e is connected to the extension 111 of the inner element 110 indirectly by the lever 130a, 130b, 130c - as already described above.

By turning or pivoting the lever 130 a, 130 b, 130 c from the closed position S in the open position 0 of the Distance of the inner member 110 increases to the can wall 2, so that the fixing device 12 is no longer applied to the edge of the can opening 3. Consequently, the user can pivot the outer member 120e and hence the entire locking device 100e around the bearing means 6 so that the can opening 3 is exposed. By turning again in the opposite direction, the lever 130a, 130b, 130c can again be brought into the closed position, whereby the can wall 2 is again braced by the outer element 120e and the inner element 110, so that the closure device 100e is not opposite the can wall 2 can be pivoted. This serves to prevent the closing device 100e from tilting back over the can opening 3 due to gravity by tilting the can 1 for the purpose of drinking.

On the can wall 2 or in the can wall 2, a fixing device 8 in the form of a protuberance 8 is realized. The fixation device receptacle 8 serves to hold the fixing device 12 in the fixing device receptacle 8 when the can opening 3 is open and when the lever 130a, 130b, 130c is in the closed position S, so that the orientation of the inner element 110 with respect to the can wall 2 is not tilted , Thus, the inner member 110 is parallel to the can wall 2 and parallel to the outer member 120e.

It can be seen from FIGS. 24 and 26 that the fixing device 8 is designed in the shape of an arc, so that the closure device 100e can be locked in arbitrary positions or pivoting positions, so that the can opening 3 need not necessarily be completely uncovered by the user for drinking , Hereinafter, a modification of the third embodiment of the shutter device according to the present invention will be described with reference to Figs. FIG. 28 shows a schematic axial cross section through the modification of the closure device according to the third embodiment and through a can 1 pressed onto the closure device. The can wall 2 of the can 1 is designed such that it has outer element guiding devices 7 in the form of protuberances. The outer element 120 a, 120 b, 120 c, 120 d of the closure device is arranged between the two outer element guide devices 7. The outer element guide devices 7 are located over the outer element 120a, 120b, 120c, 120d. However, the outer element guiding devices 7 could also be designed so that they do not protrude over the outer element 120a, 120b, 120c, 120d, but extend perpendicularly from the can wall 2, so that the outer element 120a, 120b, 120c, 120d would also be performed by such configured outer element guide means 7. The other operation of the closure device is identical to the operation of the closure device, as has been described with reference to Figures 1 to 16. FIG. 27 shows the inner element 110, which can be designed in the same way as the inner element 110 used in the closure device 100e described above with reference to FIGS. 22 to 27. Consequently, in the closed position S of the lever 130a, 130b, 130c, the fixing device 12 abuts the edge of the can opening 3, so that the outer element 120a, 120b, 120c, 120d can not be displaced with respect to the can wall 2.

FIG. 31 shows a top view of the can wall 2 of the can 1, which by means of the alternative of the third embodiment. Form of the closure device can be closed. On the can wall 2, two outer element guide means 7 are realized in the form of protuberances 7, which guide the outer member 120a, 120b, 120c, 120d along a direction of displacement. In addition, on the can wall 2 a Fixiereinrichtungsaufnähme 8 is formed, which is realized in the form of a protuberance 8. This protuberance 8 serves to receive the fixing device 12 with the can opening 3 exposed and the lever 130a, 130b, 130c in the closed position S, so that the inner element 110 is aligned parallel with respect to the can wall 2.

Figure 29 shows a plan view of the can wall 2, the can opening 3 is closed by means of the closure device according to the alternative embodiment of the third embodiment. FIG. 30 shows a plan view of the same can wall 2, with the outer element 120a, 120b, 120c, 120d and consequently the closure device being displaced relative to the can wall 2. The outer member 120a, 120b, 120c, 120d is guided by the outer member guide 7, so that the shutter can be displaced only along one direction. Consequently, it is not necessary for the outer element 120a, 120b, 120c, 120d to have a first guide device 22 on its side facing the can wall 2. However, with a corresponding geometric configuration of the can opening 2, the outer element 120a, 120b, 120c, 120d could further comprise the first guide device 22 described above with reference to FIGS. 12a and 12b.

The third embodiment of the closure device according to the present invention has been described with reference to the figures 22 to 31 realized by means of an actuating device 130a, 130b, 130c in the form of a lever. However, the third embodiment of the shutter device according to the present invention could also be realized such that the actuator is realized in the form of a screw device as described in the second embodiment of the present invention.

The present invention discloses a closure device 100a, 100b, 100c, 100d, 100e, 200a, 200b by means of which a can 1 can be resealed. Due to the possibility of displacement of the closure device 100a, 100b, 100c, 100d, 100e, 200a, 200b, the can opening 3 of the can 1 is accessible, so that through the can opening 3, for example, a straw can be inserted. Furthermore, it is achieved by the closure device 100a, 100b, 100c, 100d, 100e, 200a, 200b according to the present invention that, for example, the lips of a user of a beverage can 1 come into contact only with the can 1 or the can opening 3, and not with the closure device 100a, 100b, 100c, 100d, 100e, 200a, 200b itself, so that an increased hygiene is achieved because on the outside of the closure device 100a, 100b, 100c, 100d, 100e, 200a, 200b soiling, for example by contact may occur in conventional closure devices according to the prior art by the user of the can by mouth. This risk of picking up, for example, bacteria is minimized by the closure device 100a, 100b, 100c, 100d, 200a, 200b. Reference list:
