Hereinafter, several preferred embodiments will be described with particular reference to the three aspects discussed above. In these embodiments, like features have the same reference numerals.

First embodiment

First, a first embodiment of a container closure device according to the invention will be described which comprises all of the three aspects of the present invention as well as additional preferred embodiments.

First of all, in particular on the FIGS. 1 to 17 Referenced. Thereafter, a container closure device 10 according to the invention for a container, which is in particular in the form of a beverage can, a container wall 20 (in the form of a lid) with an inner side 21, an outer side 22 and a container opening 23 for emptying the container contents (see in particular Fig. 1 to 3 ).

The container closure device 10 comprises a closure device 30 with a closure part 40 for the multiple opening and reclosing of the container opening 23 and an operating device 50 with a control part 60 for actuating the closure part 40 (see in particular FIG Fig. 1 to 7 ). The closure member 40 is pivotally mounted on the inner side 21 about a first axis A which extends (substantially) parallel to the inner side 21 and from a closed position adjustable in an open position. The operating part 60 is arranged rotatably on the closure part 40 about a second axis B, such that the operating part 60 can be rotated from a locking position into an unlocking position (and vice versa). Preferably, the operating part 60 is further arranged rotatably about the second axis B on the closure part 40 such that the operating part 60 is connected to the closure part 40 through the container opening 23. The axes A and B preferably extend (substantially) perpendicular to each other. The axis A is preferably slightly below the inner side 21 and is provided by the closure device 30 and the closure part 40, respectively. The axis B preferably runs in the locking position and in the unlocked position (essentially) perpendicular to the container wall 20, the closure part 40 and / or the operating part 60. In the locking position, the closure part 40 closes the container opening 23 and in the unlocked position the container opening 23 can pass through Pivoting the closure member 40 to be released about the first axis A. In other words, in the unlocked position, the operating part 60 and the closure part 40 are still (substantially) aligned parallel to the container wall.

In this context, the show Figures 10 and 13 the locking position and the Figures 11 and 14 the unlocked position. Furthermore, the show Figures 12 and 15 an at least partially open position of the closure member 40 with an opening angle a by pivoting the closure member 40 about the first axis A in the interior of the container.

Both in the locking position and in the unlocked position, the operating part 60 is connected (in particular exclusively) through the container opening 23 through to the closure part 40, wherein the operating part 60 is arranged rotatably about the second axis B on the closure part 40. For the rotatable connection of the operating part 60 and the closure part 40, a connection projection 69 and a connection receptacle 43 are provided, wherein the one part of the control part 60 and the closure part 40 comprises the connection projection 69 and the other of the control part 60 and the closure part 40 comprises the connection receptacle 43. In this case, the rotatable connection by means of connecting projection 69 and Connection receptacle 43 is preferably designed as a latching connection 90 (clip connection) (see Fig. 5 . 6 . 13-17 . 18 ). For this purpose, the control panel 60 with its underside (see Fig. 5 ) on the top of the closure member 40 (see Fig. 1 ) are pressed so that connecting projection 69 and connection receptacle 43 latch together and in the latched arrangement relative to each other about the second axis B are rotatable. The latched arrangement is particularly in Fig. 18 shown. Here, the latching connection 90 comprises two latching connection means 91, 92, wherein at least one of which is at least partially elastically designed to enable the latching, and wherein a latching connection means 91 on the control panel 60 and the other latching connection means 92 is provided on the closure member 40. The latching connection means 91, 92 are each formed as latching cams and formed integrally with the connection projection 69 and the connection receptacle 43. According to Fig. 18 the connecting projection 69 is formed integrally with the operating part 60 and protrudes from the underside of the operating part 60. The connection receptacle 43 is preferably formed as a recess in the closure part 40.

Alternatively and as in Fig. 19 shown, the connecting projection 69 may be part of the closure part 40 'and the connection receptacle 43 Bestanteil of the control panel 60'. Further, the connecting projection 69 may be annular, disc-shaped and / or web-shaped (see in particular Fig. 5 . 18 and 30 ).

The following is with reference to the FIGS. 20 to 23 an alternative embodiment of the rotatable connection of the control part 60 and closure member 40 described. For this purpose, the rotatable connection of operating part 60 and closure part 40 is designed as a bayonet connection. In this case, the closure part 40 preferably comprises the connection projection 69 and the operating part 60 comprises the connection receptacle 43, as shown in FIG Fig. 19 is indicated.

The bayonet connection has two bayonet connection units 94 and 95, wherein the one bayonet connection unit 94 on the closure part 40 (see Fig. 20 and 21 ) and the other bayonet connection unit 95 on the operating part 60 (see Fig. 22 and 23 ) is provided.

The bayonet connection unit 94 has at least one bayonet flange 96, wherein the bayonet flange 96 extends substantially parallel to the plane of the closure part 40. As in the Figures 20 (Side view) and 21 (top view), the bayonet connection unit 94 has a plurality of, for example four, bayonet flanges 96. The bayonet connection unit 94 is in this case arranged on the connection projection 69 already explained above (see above) Fig. 19 ). Preferably, the connection protrusion 69 protrudes upward from the closure member 40, and the bayonet connection unit 94 is formed at the outer free end of the connection protrusion 69.

The bayonet connection unit 95 has at least one bayonet recess 97, wherein the bayonet recess 97 extends substantially parallel to the plane of the operating part 60. As in the Figures 22 (Top view) and 23 (bottom view), the bayonet connection unit 95 has a plurality, for example four, bayonet recesses 97. The bayonet connection unit 95 is in this case arranged on the connection receptacle 43 already explained above (see above) Fig. 19 ). Preferably, the connection receptacle 43 forms a recess or an opening and the bayonet connection unit 95 is formed on the edge or in the edge region of the connection receptacle 43.

Both the bayonet flanges 96 and the bayonet recesses 97 are preferably spaced apart along a notional circular line and disposed alternately to facilitate the bayonet connection.

These two bayonet connection units 94, 95 can cooperate in such a way that when the control unit 60 is applied or placed on the closure part 40, the bayonet flanges 96 are inserted into the associated bayonet recesses 97 until, viewed in a side view, they offset one another in two height-wise different adjacent ones Layers are located. Subsequently, operating part 60 and closure part 40 are parallel in one plane to the operating part 60 or closure part 40 is rotated relative to each other to bring the bayonet connection in its fixing position. Preferably, in addition, a locking device, in particular the locking connection 90 mentioned above, are provided in order to secure the bayonet connection in its fixing position.

Furthermore, it is provided, in particular Fig. 4 it can be seen that the operating part 60 has a first end region 63 and a second end region 64 and an intermediate midsection 65. Preferably, the first end portion 63 forms a first locking portion 61 and the second end portion 64 forms a second locking portion 62. The locking portions 61, 62 and / or the end portions 63, 64 may be used to operate the operating portion 60. The middle section 65 serves for the above-described embodiment of the rotatable connection between the control part 60 and the closure part 40. The control part 60 may comprise a grip region 66 with a hole 67. Alternatively, the hole 67 may be omitted. The grip region 66 is used for gripping by means of one or more fingers for operating the operating part 60.

The first locking portion 61 and the second locking portion 62 are formed such that the two locking portions 61, 62 extend beyond the container opening 23 in the locking position to an opening limiting area 24 delimiting the container opening 23 (see in particular FIG Fig. 10 . 13 . 17 ). In the unlocking position, at least one of the two locking sections 61, 62 does not extend beyond the container opening 23 and thus also not into the opening limiting area 24 delimiting the container opening (see in particular FIG Fig. 11 . 14 . 16 ). Starting from the unlocking position, the operating part 60 can pivot together with the closure part 40 down into the interior of the container (see Fig. 12 . 15 ).

In this case, the pivoting as a result of the positioning and extension direction of the first axis A and in consequence of the dead weight of the closure member 40 and / or control panel 60 done. Alternatively or additionally, the pivoting of the closure part 40 by means of a lifting of the second end portion 64 of the operating part 60 in a direction substantially perpendicular or obliquely to the container wall 20. Depending on the size and material of the closure part 40 and the control part 60 arranged on it and depending on the configuration of the joint 37, the opening angle a to be achieved as a result of gravity can be influenced. Depending on the desired opening angle, the closure member 40 may then remain in this intermediate position as a final open position or the closure member 40 may be further pivoted by lifting the second end portion 64 about the first axis A, so that a larger opening angle can be achieved as the final open position.

The container opening 23 is bounded by a boundary line 25. Preferably, the container opening 23 has a substantially oval basic shape or the shape of a slot. In this case, the longitudinal sides of the slot may be formed in sections in a straight line. The curved end portions of the elongated hole may be preferably formed semicircular or elliptical. The opening delimitation area 24 is delimited on the one hand by the delimiting line 25 and, on the other hand, delimited by a (fictitious) edge line 27 which is congruent or substantially parallel to it. Thus, the opening restricting portion 24 extends around the container opening 23 and has a ring shape and / or an oval shape.

Alternatively, the particular in the FIGS. 4 and 5 shown operating part 60 may also be formed entirely without handle portion 66, so that only the central portion 65 and the two locking portions 61, 62 and the two end portions 63, 64 are present, and therefore the control unit 60 could also have a slot shape or oval shape.

As can be seen from a synopsis of FIGS. 1 to 7 results, a control panel outer edge 68 of the control panel 60 is formed substantially congruent to the boundary line 25 of the container opening 23, such that only a minimum gap of constant width between the control panel outer edge 68 and the boundary line 25 is provided so that the control panel 60 from the unlocked position Pivoting the closure member 40 about the first axis A can be pivoted into the interior of the container.

When the operating part 60 is rotated from the locking position into the unlocking position, the two locking sections 61, 62 move at least in sections along the opening limiting area 24 and / or along the boundary line 25 of the container opening 23. During the rotary movement from the locking position into the unlocking position, an overlapping area of the first latching portion 61 having the opening restricting portion 24 and an overlapping portion of the second latching portion 62 having the opening restricting portion 24 continuously smaller. Accordingly, in the case of a reverse rotational movement from the unlocking position into the locking position, the aforementioned respective overlapping area in each case becomes continuously larger.

For the pivotable attachment of the closure part 40 on the inside 21 of the container wall 20 (see in particular Fig. 14, 15th and 33 to 37 ), the closure device 30 or the closure part 40 comprises a joint 37, which is designed in the form of a thin-walled material cross-section, and hingedly connects the closure region 31 with a fastening region 32 and provides the first axis A.

The attachment portion 32 is for example in the FIGS. 6 and 13 to 15 indicated and in the FIGS. 33 to 37 shown in more detail. The attachment region 32 is preferably formed integrally with the closure region 31, that is, the closure device 30 of the closure region 31 and the attachment region 32 is made of a material in one piece, preferably of an injection molding material, such as plastic.

A main body 33 of the attachment portion 32 comprises a first main body portion 38 and a second main body portion 39. Further, the attachment portion 32 includes another hinge 84, which is also in the form of a thin-walled material cross-section is formed and connects the first main body portion 38 with the second main body portion 39 articulated.

By this formation of the joints 37 and 84 it is possible that the closure means 30 in the in Fig. 33 can be easily produced, for example, by means of an injection molding process in a corresponding shape and then the second main body portion 39 can be folded down due to the resulting by the thin walls of the joint 84 elasticity to the position shown in FIG Fig. 35 is reached. Here, a projection may be provided on the underside of the first main body portion 38, which engages when folding in an associated recess in the second main body portion 39. For example, a locking connection between this projection and the receptacle can be formed. Alternatively, a fluid connection of the sections 38 and 39 may be provided, for example by gluing.

The main body 33 also has one or more support portions 35 for abutment against the inner side 21, which project upwardly from the main body 33. Furthermore, a protrusion 34 protrudes upwards from the main body 33, which is passed through a mounting opening 26 of the container wall 20 for attachment until the support region 35 comes into contact with the inner side 21. Subsequently, the protruding part of the projection 34 can be deformed to form a rivet connection 36 (see FIGS. 34 and 35 ).

Hereinafter, the seal 110 of the container closure device 10 will be described with particular reference to FIGS FIGS. 1 . 8th . 9 . 16, 17 explained in more detail.

Fig. 52 shows the closed position of the valve device 100, in which a projecting portion of the underside of the operating part 60, the valve opening 101 and / or the end of the valve channel 102 closes.

Hereinafter, the sealing device 120 will be explained in more detail. In this regard, three embodiments of the sealing apparatus 120 will be described. The sealing device 120 is optically and / or acoustically visibly damaged when the container closure device 10 is first opened for the user. The first embodiment of the sealing device 120 is in the Figures 42 to 47 The second embodiment is shown in FIGS FIGS. 53 to 60 and the third embodiment is shown in FIGS FIGS. 61 to 64 shown.

The sealing device 120 according to the first embodiment ( Fig. 42 to 47 ) comprises a sealing projection 121, a sealing recess 122, at least one web 123 and a gap 124. The sealing device 120 is visibly and / or acoustically visibly damaged when the container closure device 10 is opened for the first time. The sealing projection 121 is connected, for example via two webs 123, which serve as a Sollbeschädigungsstelle with the control panel 60. In this case, the sealing projection 121 is preferably integrally formed with the operating part 60. Preferably, the sealing projection 121 is connected to the operating part 60 via one or more webs 123 as the at least one desired damage location. At or in the closure part 40, the associated sealing recess 122 is provided. In the not yet damaged state before a first-time opening, the sealing projection 121 projects into the sealing recess 122. The sealing projection 121 protrudes into the sealing recess 122 in that it touches in the region of the protruding free end with its end face the closure part 40, in particular the bottom of the sealing recess 122. Alternatively, a distance between the front side of the sealing projection 121 and the closure part 40 may be present. Further, the webs 123 allow the formation of a gap 124 between the sealing projection 121 and the operating part 60. When the operating part 60 is rotated starting from the locking position of the operating part 60, the sealing projection 121 cooperates with the sealing recess 122 such that at least one of the webs 123 is damaged becomes. In this case, the sealing projection 121 abuts against a wall 125 of the sealing recess 122 and the Sollbeschädigungsstelle is damaged, that is, at least one or all webs 123 break or break instead deform or expand the webs visible together with the sealing projection 121, so that this over the upper edge of the operating part 60 protrudes.

In the second embodiment ( FIGS. 53 to 60 ), the sealing device 120 comprises a sealing projection 121 and a sealing recess 122, wherein the sealing projection 121 is connected to the operating part 60 via at least one predetermined damage location, preferably via three webs 123. The sealing recess 122 is formed in the operating part 60. The sealing projection 121 is formed in one piece with the operating part 60 via the at least one web 123. The sealing projection 121 extends substantially perpendicular to the operating part 60 and the closure part 40 and thus substantially parallel to the second axis. The sealing projection 121 is formed in this embodiment as a pin and includes a first end 128 and a second end 129. The sealing projection may also be formed in T- or L-shape (not shown for simplicity). Preferably, the first end 128 is located in the region of the control part 60 and the second end 129 in the region of the closure part 40. In other words, in the region of the first end 128 by means of the webs 123, a first connection 126 between sealing projection 121 and operating part 60 is present is damaged when first opening the container closure device 10. In the region of the second end 129, a second connection 127 between sealing projection 121 and closure member 60 is provided, the first opening of the Container closure device 10 and will not be damaged later. Sealing projection 121 and sealing recess 122 cooperate in such a way that upon rotation of the operating part for the first time opening of the container closure device, the sealing device 120 is damaged. In principle, the first connection 126 and / or the second connection 127 may be formed as a cohesive, non-positive and / or positive connection. In the present embodiment, the first connection 126 is integrally formed by means of the above-described webs 123 and the second connection 127 is preferably a material connection, for example by means of welding (eg ultrasonic welding) or gluing.

Like from the FIGS. 53 to 60 can be seen, the sealing recess 122 is formed as a slot, wherein the slot is formed as a through hole, that is, extends over the entire component thickness of the control panel 60. The sealing recess 122 is arcuate, preferably semicircular, formed (see Fig. 53, 54 ; 59, 60 ). In this case, the circle center is preferably located on the second axis. As a result, the cooperation of sealing projection 121 and sealing recess 122 can support the recurring rotational movements for re-opening and reclosing even after the first opening.

As in particular from the FIGS. 55 to 58 can be seen, the sealing projection 121 is integrally connected in one end region of the executed as a slot Siegelausnehmung 122 via the plurality of webs 123 with the control panel 60, wherein the sealing projection 121 extends substantially perpendicular to the control panel 60.

Due to this configuration is after a first opening by turning the control panel 60 after breaking the webs 123 (see Fig. 56 ), that is, after disconnecting the first connection 126, during rotation of the operating part 60, the operating part 60 can be moved along the sealing recess 122 (preferably in the form of the oblong hole) relative to the sealing projection 121. While the twisting of the operating part 60, the closure member 40 remains in its position, that is, it does not twist, whereby the control panel 60 is guided by means of its sealing recess 122 along the stationary sealing projection 121.

The sealing device 120 according to the third embodiment ( FIGS. 61 to 64 ) corresponds to the shape of the sealing recess 122 of the above-explained second embodiment. Thus, the FIGS. 55 to 58 analogous to third embodiment. In the present third embodiment, the sealing recess 122 formed as an elongate hole is formed in the shape of a quarter circle, in contrast to the semicircular configuration of the second embodiment (see FIG FIGS. 61 to 64 ). Incidentally, reference is made to the explanation of the second embodiment.

Furthermore, the closure device 30 comprises a fixing device 80, with which in a fixing position, the closure member 40 is detachably fixable in the open position and in a release position, the closure member 40 is pivotable between the closed position and the open position. For further explanation of the fixing device 80 is in particular to the FIGS. 16, 17 and 33 to 47 directed. This is in the FIGS. 16 and 17 and 31 and 32 each show the release position of the fixing device, in which the closure part 40 is pivotable between the closed position and the open position. In the FIG. 37 the fixing position of the fixing device 80 is shown.

In a preferred embodiment, the fixing device 80 is designed as a latching device 81. For stability reasons, two locking devices 81 are preferably provided, which are positioned symmetrically to a longitudinal axis of the closure part 40 (see in particular FIGS. 6 and 7 ). These two latching devices 81 are preferably arranged in the end regions or at the ends of the first axis A. The latching device 81 has a first latching element 82 in the form of a latching cam (or latching projection) and a second latching element 83 in the form of a latching receptacle (or latching recess). One of the locking elements 82, 83 is at the closure portion 31 of the closure member 40 and the other of the locking elements 82, 83 provided on a mounting portion 32 of the closure member 40 or integrally formed. Like from the FIGS. 33 to 37 can be seen, the locking cam 82 may be formed in the region of its free end, for example, curved or curved. Alternatively, a sectionally linear or oblique shape or combinations thereof can be selected. Accordingly, the locking receptacle 83 is substantially shaped so that upon pivoting of the closure member 40 about the first axis A in the interior of the container, the two latching elements 82 and 83 can engage each other to obtain the fixing position. Accordingly, upon pivoting back of the closure member 40 about the first axis A, the two latching elements 82, 83 again disengage to obtain the release position and to allow a closure of the container opening 23. Preferably, the first locking element 82 and / or the second locking element 83 is at least partially (bending) elastic. The pivoting back can be achieved by pressing the second end portion 64 and the handle portion 66, respectively.

The following is with reference to the FIGS. 38 to 41 an alternative embodiment of the fixing device 80 described. For this purpose, the fixing device 80 is designed as a latching device 81.

The latching device in turn has a first latching element and a second latching element, wherein at least one of them is at least partially elastic, and wherein one of the latching elements on a closure portion 31 of the closure part 40, which serves to close the container opening, and the other latching element to a mounting area 32 of the closure part 40, which serves for fastening the closure device on the inside of the container wall, is provided.

The arranged on the mounting portion 32 locking element is preferably designed as a latching cam 88 (or latching projection). Preferably, the locking cam 88 is integrally formed with the closure member 40 and attached there to the underside and to the mounting portion 32 of the closure member.

The other latching element arranged on the closure region 31 is preferably designed as a latching flange 85 (or latching recess). Preferably, the locking flange 85 is formed integrally with the closure member 40. The latching flange 85 may include a first flange portion 86 and a second flange portion 87. Preferably, the latching element is designed as a hook-shaped or L-shaped flange (viewed in cross section). Here, one end of the flange is attached to the closure portion 31 of the closure member 40 and the other end of the flange 85 is formed as a free end, which can cooperate in the fixing position of the fixing device with the other locking element 88.

The two flange portions 86, 87 of the flange 85 may be substantially perpendicular to each other or at a predetermined angle to each other. In particular, the free end of the flange portion 87 may be formed elastically bendable to come by bending and / or pressing the free end in contact with the other locking element 88, so that the fixing position of the closure portion 31 of the closure member 40 can be maintained.

How out Figure 38 can be seen, the locking cam 88 may be formed in the region of its free end, for example, curved or curved. Alternatively, a sectionally linear or oblique shape or combinations thereof can be selected.

Accordingly, the locking flange 85 is substantially shaped so that upon pivoting of the closure portion 31 of the closure member 40 about the first axis A in the interior of the container, the two locking elements 85 (or 87) and 88 can engage each other to the Hold fixation position. Thus, upon pivoting back of the closure portion 31 of the closure member 40 about the first axis A, the two locking elements 85 (or 87), 88 again disengage to obtain the release position and to allow a closure of the container opening 23. Preferably, the first locking element 85 and / or the second locking element 88 is at least partially (bending) elastic. The pivoting back can be assisted by pressing the second end region 64 or the grip region 66.

As already above to the FIGS. 33 to 37 are also explained in the FIGS. 38 to 41 the locking elements in the release position of the fixing device spaced from each other. In the fixing position, the latching elements are positively, frictionally or non-positively connected to each other or in engagement.

Alternatively, it is also possible to provide two of the above-described latching devices, which are arranged at a distance from one another on the closure part 40. These two latching devices are preferably positioned symmetrically to a longitudinal axis of the closure part 40.

Furthermore, the container closure device 10 according to the invention comprises an adjustment mechanism 70 (see FIGS. 24 to 32 ), with which the closure part 40 or the operating part 60 (due to the rotation of the operating part 60 relative to the closure part 40) is movable toward or away from the container wall 20 in a direction substantially perpendicular to the container wall 20. During a movement in the direction of the container wall 20, the operating part 60 and / or the closure part 40 is pressed against the container wall 20. On the other hand, the operating part 60 and / or the closure part 40 is released during a movement in the direction away from the container wall 20 away from the container wall 20.

The adjusting mechanism 70 comprises at least one adjusting means 71, which may be provided on the container wall 20 on the operating part 60 and / or on the closure part 40.

In a first variant, the adjusting means 71 is formed on the container wall 20, as from the FIGS. 24 to 26 to recognize. Here, the adjusting means 71 is formed as a projection 72 or elevation of the container wall 20. This is in FIG. 25 in a cross section the in FIG. 24 shown in an unlocking position shown. Based on this, by rotating the operating part 60 about the second axis B, that is to say about an axis extending perpendicularly to the container wall 20, the operating part 60 is transferred into the locking position, which in FIG FIG. 26 is shown. Shortly before reaching the locking position, the one end of the control unit 60 runs on the projection 72 and that until the locking position is reached, in which the control unit 60 rests on the highest point of the projection 72. Between the beginning of the casserole and the reaching of the highest point of the projection 72, the closing part 40 resting against the underside of the opening limiting region 24 is moved toward the container wall 20 in a direction perpendicular to the container wall 20. As a result, a pressing of the closure part 40 to the container wall 20 and / or a mutual pressing of the operating part 60 and the closure part 40 is achieved. In this case, the seal 110 is compressed. In the reverse rotation is starting from the position in Fig. 26 the control panel 60 in the position according to Figures 24 or 25 turned back, whereby the contact pressure or the squeezing of the operating part 60 and closure part 40 or between the closure part 40 and the container wall 20 is released again. In this respect, the closure part 40 in particular is moved away from the container wall 20 in a direction perpendicular to the container wall 20.

In an alternative embodiment according to the FIGS. 27 to 29 the adjustment means 71 is provided on the closure part 40, in particular on the connection projection 69. Here, the adjusting means 71 is formed as a control section 73 which is shaped so that the control section 73 causes a control of the movement of the closure member 40 or control panel 60 on the container wall 20 to or from the container wall 20 away. How out Fig. 27 can be seen, the control section 73 is preferably formed by an edge 74, the the inner periphery of the closure member 40 is formed. The edge can also be referred to as a starting edge or run-on slope.

The FIGS. 30 to 32 show analogous to the FIGS. 27 to 29 also such an edge 74 on the connecting projection 69 of the closure part 40 '. However, this is appropriate FIG. 19 provided that the operating part 60 'has a connection receptacle 43 and the closure part 40' has a connection projection 69 for the rotatable connection of the operating part 60 'and the closure part 40'. But it is also possible that such an edge 74 is not arranged on the closure part but on the connecting projection 69 of the control panel or simultaneously on the closure member 40 and the control panel 60th

Further modifications:

With reference to the Figures 65 to 72 may be provided in further embodiments of the container closure device according to the invention one or more of the following modifications:
In a preferred embodiment according to FIGS. 65 and 66 a lever bearing device 140 is provided which, during the pivoting movement of the closure part 40 from the open position into the closed position, enables a lever action such that the pivoting movement of the closure region 31 of the closure part 40 towards the inner side 21 of the container wall 20 is supported up to the closed position of the closure part 40. Thus, by a downward pressure on the end of the operating part 60 (in particular in the region of Grip area 66), the lower edge (underside) of the operating part 60 are brought above the container wall 20, in order then to allow the rotational movement of the operating part 60 relative to the closure part 40. At the same time, the upper side 46 of the closure part 40 and a seal optionally arranged there can be applied and / or pressed against the inside (underside) 21 of the container wall 20.

As in the Fig. 65, 66 1, the lever support device 140 comprises a support element in the form of a flange 141, which is arranged or formed on the operating part 60 and is preferably formed integrally with the operating part 60. Preferably, the flange 141 extends substantially perpendicular to the plane of extent of the operating part 60 and protrudes downward from the operating part 60. Alternatively (not shown), the flange 141 extends at a predetermined angle to the plane of extent of the operating part 60, for example in a range of 10 ° to 80 °, in particular in a range of 30 ° to 60 °.

In the in the FIGS. 67 and 68 In the embodiment shown, the lever support device 140 comprises a first support element in the form of a projection 142 which is arranged or formed on the operating part 60 and protrudes downwards and a second support element in the form of a projection 143 which is arranged or formed on the container wall 20 and upwards protrudes. The protrusion 142 is preferably formed integrally with the operating part 60, and the protrusion 143 is preferably an integral part of the container wall 20. The protrusion 143 may be embodied as embossing in the container wall 20 and may be V-shaped, for example.

The support elements 142 and 143 are arranged opposite each other and further dimensioned and aligned with each other so that they cooperate in the course of the pivotal movement of the closure member 40 from the open position to the closed position, that the lever action on the closure portion 31 of the closure member 40 can be achieved.

The fact that the protrusion 142 protrudes downwards in the direction of the container wall 20 and the protrusion 143 upwards in the direction of the operating part makes it possible for the two support elements 142, 143 to move from the open position to the closed position in the context of the pivoting movement of the closure region 31 of the closure part 40 Area of the final movement path come into contact with each other, so that the leverage can be achieved.

The in the FIGS. 65 to 68 are shown and arranged on the operating part 60 support members 141 and 142 are arranged in the region of the locking portion 22 and / or the handle portion 66 of the operating part 60 that the support member 141 and 142 adjacent to the first axis A.

In the in the Figures 69 and 70 As shown, the handle portion 66 of the end portion of the operating portion 60 is angled or bent relative to the plane of extent of the operating portion 60. In this way, a leverage can be generated because a larger lever arm and / or a greater distance of the end of the handle portion is given to the container. In this embodiment, the Hebelauflagereinrichtung is not required, but may also be present.

In the in the FIG. 71 In the embodiment shown, the operating part 60 comprises an upper side 130, a lower side 131 and a peripheral side edge 132, wherein the side edge 132 and / or the lower side 131 has two abutment surface sections 133, 134, which respectively extend obliquely or bent and are positioned and formed in this way that the contact surface portions 133, 134 cooperate with a rotation of the operating part 60 of the unlocked position into the locking position with the container wall 20. The contact surface portion 133 is preferably located in the region of the portion 62 and / or 65 of the operating part 60. The contact surface portion 134 is preferably in the region of the portion 61 and / or 63 of the operating part 60. As in Fig. 71 shown, the abutment surface portions 133, 134 are positioned on opposite sides of the control panel 60.

At an in FIG. 72 In the embodiment shown, the closure part 40 has a continuously variable component thickness in a section extending perpendicularly to the container wall 20. Preferably, for this purpose, the bottom 47 of the closure member 40 is convex. In this case, a base plate 48 of the closure part 40 is provided with a component thickness increasing along the longitudinal direction of the closure part 40 from outside to inside. This results in a sectionally different elasticity for the closure part 40, which, in particular in connection with the pressure present in the interior of the container, enables an improved sealing effect, stability or elasticity in the desired regions of the closure. Alternatively or additionally, the bottom 47 may be formed step-shaped.
