Description


[0001] The invention relates to a container, specifically to a container comprising an easy open end.

[0002] Containers with easy open ends are e.g. used for CLUB cans. These containers, including the end, are typically made of sheet metal. Foodstuff, e.g. seafood, is commonly housed in these containers.

[0003] Typically the containers and the corresponding ends are provided to a customer, i.e. food manufacturer, separately in large quantities. The customer can fill the container with foodstuff, e.g. seafood, and close the opening of the container with the end (the lid), e.g. by a double seam.

[0004] Filled containers are presented at a point of sale in e.g. a supermarket for customers. Such containers are typically stacked in order to save precious room at store shelfs. Known containers that comprise a bead for enhanced stability and/or a depression in the end close to a pull-tab for facilitating access to the pull-tab are not stackable with a sufficient stability of the stack.

[0005] A problem to be solved by the invention is to provide an end for a container that allows stacking of a plurality of containers with such ends with increased stability of the stack. A further problem to be solved is to provide a container with such an end that allows a stacking of a plurality of such containers with increased stability.

[0006] This problem is solved by a container according to claim 1 or by a stack of at least two containers according to claim 15.

[0007] A container can comprise an end, specifically an easy-open-end, and a container body. The end comprises a central panel that defines an x-y-plane. A z-direction is perpendicular to the x-y-plane. A tab is attached, for example via a rivet, to the end and the tab extends in a positive z-direction. Preferably the tab is attached to the central panel and the tab extends in a positive z-direction from the x-y-plane of the central panel.

[0008] The end comprises at least one stabilizing bead that is shaped in the end and extends in the positive z-direction. Preferably the stabilizing bead is shaped in the central panel and extends in the positive z-direction from the x-y-plane of the central panel. The container body comprises a lower surface that can be located on an opposite side of the container than the end. The lower surface may be a flat surface.

[0009] The container as a first container is configured to be stacked with a second container, wherein the second container comprises a second end with a second central panel, such that a portion of the lower surface of the container contacts a portion of the second end of the second container. The central panel of the (first) container is parallel ±2.0 ° to the second central panel of the second container. The (first) container and the second container are same containers. The (first) end of the (first) container and the second end of the second end are same ends.

[0010] Same containers and same ends are to be understood as containers and ends that are configured equally.

[0011] Thereby, a stacking of (e.g. at least ten) containers is increased.

[0012] The x-y-plane is a reference plane for claimed and described extensions of elements. An extension is measured as a distance in z-direction between the x-y-plane and a second plane that is defined by the respective element itself.

[0013] The end may be an easy-open-end comprising a tab, preferably a pull-tab, and a score line as a mechanically weakened portion in the end. For example, the tab of the end can be attached to the central panel of the end such that a lifting movement of a rear portion of the tab forces a front portion (nose portion) of the tab towards the score line of the end in order to break a portion of the end. A consumer may then pull the tab away from the container in order to remove a large portion of the end. Thereby, the container can be opened and the filling of the container can be accessed.

[0014] The central panel of the end may be the largest portion (by area) of the end extending in the same plane, e.g. an x-y-plane.

[0015] The tab may be a pull-tab comprising a finger hole for allowing a human finger to reach through the tab. The tab may be attached to the central panel or to another portion of the end e.g. via rivet.

[0016] Preferably, the tab extends between 1.4 mm and 2.5 mm, preferably between 1.7 mm and 2.2 mm, more preferably between 1.8 mm and 2.0 mm, in a positive z-direction that is perpendicular to the x-y-plane of the central panel. It is especially preferred that the tab extends about 1.95 mm in the positive z-direction.

[0017] Generally, when an extension of an element, e.g. extension of the tab, stabilizing bead, (at least one) bulge, depression or second bead, is described, the extension is measured as the distance in z-direction between the x-y-plane that is defined by the central panel and a second plane that is defined by the respective element. The second plane is parallel to the x-y-plane and is defined by a portion of the respective element that has the greatest distance from the x-y-plane in the z-direction.

[0018] The extension of an element may be the actual/physical height of the respective element in z-direction. In this case, the respective element is attached to the central panel (e.g. the tab) or may be formed in the central panel (e.g. the stabilizing bead, the bulge, the depression, the second bead). This applies the general rule of the preceding paragraph to the specific case in which the respective element is associated with the central panel.

[0019] The stabilizing bead may be substantially c-shaped, substantially circular shaped, substantially oval shaped or substantially straight shaped in the end, preferably in the central plane of the end.

[0020] The stabilizing bead may fully surround a portion of the end or may not fully surround a portion of the end.

[0021] It is preferred that the stabilizing bead extends between 0.4 mm and 2.5 mm, preferably between 0.5 mm and 1.5 mm, more preferably between 0.6 mm and 1.0 mm, in a positive z-direction that is perpendicular to the x-y-plane of the central panel. Specifically, the stabilizing bead extends about 0.8 mm in the positive z-direction.

[0022] The container body of the container may be a one piece container body. The end may be seamed to the container body, specifically via a double seam. The container body may also be a two-piece container body that may comprise a container wall and a container bottom, wherein the bottom may be seamed to container wall and the end may be seamed to the container wall.

[0023] For example, two containers may be stacked for transportation of filled containers or presentation of the containers at a point of sale. The containers may be same containers comprising same elements, specifically same container bodies and same ends. These stacked containers may be parallel ±2.0 °, specifically the central panels of the containers may be parallel ±2.0 °.

[0024] It is especially preferred that (the central panels of) the two containers are parallel ±1.5 °, ±1.0 °, or even ±0.5 °. Thereby, an increased stability of the stack is achieved.

[0025] Alternatively or additionally, the lower surfaces of the containers may be parallel ±2.0 °, preferably ±1.0 °, more preferably ±0.5 °.

[0026] The end of the container may comprise a depression that is formed in the end. The depression may extend in a negative z-direction. The depression is shaped and positioned to allow a human finger to reach at least partially below the rear portion of the tab. Thereby, a consumer can easily reach the rear portion of the tab for lifting the rear portion and opening the container as described in more detail above.

[0027] The depression can be substantially circular shaped. The depression can have an area between 80 mm2 and 500 mm2, preferably between 90 mm2 and 300 mm2.

[0028] A portion of the depression may overlap with a portion of the tab, specifically the rear portion of the tab.

[0029] Preferably, the depression extends between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.5 mm, more preferably between 1.2 mm and 1.5 mm, in the negative z-direction that is perpendicular to the x-y-plane of the central panel. It is especially preferred that the depression extends about 1.25 mm in the negative z-direction.

[0030] The extension of the tab in the positive z-direction can be equal to the extension of the stabilizing bead in the positive z-direction ±1.5 mm. Preferably the extension of the tab in the positive z-direction is equal to the extension of the bead in the positive z-direction ±0.75 mm or ±0.3 mm.

[0031] The extension of the stabilizing bead may be lower or equal to the extension of the tab in the positive z-direction. Preferably, the extension of the stabilizing bead is at most 1.5 mm, more preferably at most 0.75 mm, even more preferably at most 0.3 mm, smaller than the extension of the tab in the positive z-direction. It is especially preferred that the extension of the stabilizing bead is substantially equal to the extension of the tab in the positive z-direction.

[0032] The extension of the depression in the negative z-direction may be equal to the extension of the tab in the positive z-direction ±1.0 mm, preferably ±0.5 mm. It is especially preferred that the extension of the depression in the negative z-direction is equal to the extension of the tab in the positive z-direction ±0.2 mm.

[0033] It is preferred that the extension of the depression in the negative z-direction is equal to the extension of the stabilizing bead in the positive z-direction ±2.0 mm, preferably ±1.2 mm. Specifically, the extension of the depression in the negative z-direction is equal to the extension of the stabilizing bead in the positive z-direction ±0.8 mm.

[0034] The end may comprise at least one bulge, preferably at least two bulges. The bulge may be shaped in the end and may extend in the positive z-direction. The at least one bulge may be positioned in the proximity of the tab and associated with the tab.

[0035] Preferably, the at least one bulge is located in the proximity of an outer side of the tab that extends between the front portion and the rear portion of the tab. Specifically, a first bulge is located in the proximity of a first outer side of the tab that extends between the front portion and the rear portion of the tab and a second bulge is located in the proximity of a second outer side of the tab that extends between the front portion and the rear portion of the tab.

[0036] The extension of the at least one bulge in the positive z-direction may be equal to the extension of the tab in the positive z-direction ±2.0 mm, preferably ±1.5 mm. Specifically, the extension of the bulge in the positive z-direction is equal to the extension of the tab in the positive z-direction ±1.0 mm.

[0037] The bulge may extend between 0.4 mm and 2.5 mm, preferably between 0.7 mm and 2.0 mm, more preferably between 1.0 mm and 1.5 mm, in the positive z-direction that is perpendicular to the x-y-plane of the central panel. It is preferred that the bulge extends about 1.2 mm in the positive z-direction.

[0038] The extension of the at least one bulge may be lower or equal to the extension of the tab in the positive z-direction. Preferably, the extension of the bulge is at most 1.5 mm, more preferably at most 1.2 mm, even more preferably at most 0.9 mm, smaller than the extension of the tab in the positive z-direction. It is especially preferred that the extension of the at least one bulge is substantially equal to the extension of the tab in the positive z-direction.

[0039] The extension of the at least one bulge may be equal to the extension of the stabilizing bead ±2.0 mm, preferably ±1.2 mm, more preferably ±0.6 mm, in the positive z-direction.

[0040] The extension of the at least one bulge in the positive z-direction may also be equal to the extension of the depression in the negative z-direction ±2.0 mm, preferably ±1.2 mm, more preferably ±0.6 mm, even more preferably ±0.2 mm.

[0041] The end of the container can comprise a second bead that extends in the negative z-direction of the x-y-plane of the central panel.

[0042] The second bead can be at least partially surrounded by the (first) stabilizing bead, fully surrounded by the (first) stabilizing bead or not surrounded by the (first) stabilizing bead, preferably in a plane.

[0043] It is preferred that the second bead extends between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.5 mm, more preferably between 1.2 mm and 1.5 mm, in the negative z-direction that is perpendicular to the x-y-plane of the central panel.

[0044] The second bead and the depression may be positioned and shaped such that the x-y-plane of the central panel of the end is parallel to a flat surface ±2.0 °, preferably ±1.5 °, more preferably ±1.0 °, most preferred ±0.5 °, when the end is positioned on the flat surface.

[0045] Preferably, the second bead and the depression may be positioned and shaped such that the x-y-plane of the central panel of the end is parallel to a flat surface ±2.0 °, preferably ±1.5 °, more preferably ±1.0 °, most preferred ±0.5 °, when the second bead and/or the depression contacts the flat surface.

[0054] Fig. 1 shows an end 100 for a container. The end 100 comprises central panel 112 and a tab 140. The tab 140 is attached to the end 100, especially to the central panel 112, via a rivet 116 and the tab 140 comprises a front portion 141 and a rear portion 142.

[0055] The central panel 112 of the end 100 defines an x-y-plane. A z-direction is perpendicular to the x-y-plane. A bead 113 is formed in the end 100, preferably in the central panel 112, and extends in the positive z-direction from the x-y-plane of the central panel 112. The bead 113 is substantially c-shaped and not fully surrounds a portion of the central panel 112. Beads such as bead 113 are formed to enhance mechanical stability of an end.

[0056] Further, the end 100 comprises a depression 114 that is formed in the end 100, preferably in the central panel 112, and extends in the negative z-direction from the x-y-plane. The depression 114 has a basic circular shape and is positioned such that a portion of the tab 140, i.e. the rear portion 142 of the tab 140, overlaps the depression 114. The depression allows a consumer to reach the rear portion 142 in a more convenient manner, when the consumer intends to lift the rear portion 142 of the tab 140 in order to open the end 100.

[0057] A first bulge 120 and a second bulge 121 are formed in the end 100, preferably in the central panel 112 of the end 100. The bulges 120, 121 extend from the x-y-plane in the positive z-direction. The first bulge 120 is located close to a first side of the tab 140 that extends from the front portion 141 to the rear portion 142. The second bulge 121 is located close to a second side of the tab 140 that extends from the front portion 141 to the rear portion 142. The first side of the tab 140 and the second side of the tab 140 are opposite sides.

[0058] The bulges 120, 121 are provided to prevent a rotation of the tab 140 about the rivet 116 in a plane parallel to the x-y-plane. Such a rotation of the tab 140 prior to lifting the rear portion 142 of the tab 140 might cause the tab 140 to break since the front portion 141 of the tab 140 can attack the central panel 112 at a position that is too far away from the score line 118 as mechanically weakened portion of the end 100, preferably of the central panel 112.

[0059] The score line 118 as mechanically weakened portion is located in the end 100, preferably in the central panel 112, close to the outer edge of the end 100. The score line 118 surrounds a portion of the end 100, specifically the central panel 112. The tab 140 is positioned and shaped such that the front portion 141 of the tab 140 contacts (a portion of the end close to) the score line 118 in order to break a portion of the end 100, e.g. the central panel 112, when the tab 140 is pivoted about the rivet 116 by lifting the rear portion 142 of the tab 140. By pulling the tab 140 away from the end 100, a large portion of the central panel 112 that is surrounded by the score line 118 is removed from the end 100 and the end 100 is open.

[0060] At the outer edge of the end 100, a curl 130 (implied in Fig. 1) is positioned. The curl 130 of the end 100 can be used to attach the end 100 to a container body in order to produce a closed container. For example, the end 100 can be seamed to a container body via the curl 130.

[0061] Fig. 2a shows a first end 200 in a top view, wherein a further end 200 is indicated below the first end 200 that is rotated by 180 ° in a x-y-plane as will be discussed in more detail below.

[0062] The end 200 may be equal to the end 100. The end 200 comprises a central panel 212 that defines an x-y-plane. In the end 200, specifically in the central panel 212, a stabilizing bead 213 is formed and the bead 213 extends in a positive z-direction, wherein the z-direction is perpendicular to the x-y-plane. Further, a depression 214 is formed, preferably in the central panel 212, and the depression 214 extends in the negative z-direction.

[0063] End 200 comprises a tab 240 with a front portion 241 and a rear portion 242. The tab 240 is attached to the end 200, e.g. to the central panel 212, via a rivet 216. The depression 214 is partially overlapped by a portion of the tab 240, specifically by the rear portion 242 of the tab 240. The front portion 241 of the tab 240 may break a score line 218 that is located close to the outer edge of the end 200, when the tab 240 is pivoted about the rivet 216 by lifting the rear portion 242 of the tab 240.

[0064] Optionally, in the proximity of the tab 240, a first bulge 220 and a second bulge 221 are formed in the end 200, preferably in the central plane 212. The bulges 220, 221 extend in the positive z-direction from the x-y-plane.

[0065] A curl 230 is located at the outer edge of the end 200.

[0066] In Fig. 2a a cross section A-A is indicated that is shown in Fig. 2b and 2c.

[0067] Fig. 2b depicts a stack of ends 200a-e comprising several ends 200 as ends 200a, 200b, 200c, 200d and 200e. The ends 200a through 200e are same ends 200.

[0068] In the stack of ends 200a-e, the ends 200a-e are each rotated by 180 ° in the x-y-plane relative to the next end 200 in the stack 200a-e. For example, end 200a has the same orientation as end 200 as shown in Fig. 2a. Compared to end 200a, end 200b is rotated by 180 ° in the x-y-plane and positioned below end 200a. Compared to end 200b, end 200c is rotated by 180 ° in the x-y-plane and positioned below end 200b. Other ends of the stack 200a-e are positioned similarly.

[0069] Each of the ends 200a through 200e comprises a tab 240, wherein the tab 240 of end 200a is denoted as tab 240a and so on. Each of the ends 200a through 200e further comprises a central panel 212, a stabilizing bead 213, at least one bulge 220 and a depression 214.

[0070] With reference to Fig 2b, the depression 214a of the first end 200a in the stack of ends 200a-e may contact the central panel 212b of the second end 200b in the stack of ends 200a-e. Alternatively or additionally, the tab 240b of the second end 200b may contact the (lower side of the) central panel 212a of the first end 200a. Alternatively or additionally, the bead 213b of the second end 200b may contact the (lower side of the) central panel 212a of the first end 200a. Alternatively or additionally, the at least one bulge 220b may contact the (lower side of the) central panel 212a of the first end 200a.

[0071] It is preferred that the tab 240b of the second end 200b contacts the (lower side of the) central panel 212a of the first end 200a and the bead 213b of the second end 200b contacts the (lower side of the) central panel 212a of the first end 200a.

[0072] The central planes 212a-e of the stack of ends 200a-e are parallel and the stack of ends 200a-e shows a high stability.

[0073] In Fig. 2c a stack of ends 200a and 200b only is depicted.

[0088] A curl 330 is seamed to a container body 360a,b (see Fig. 3b) for attaching the end 300 to the container body 360a, b and to form a closed container 350.

[0089] The cross section B-B indicated in Fig. 3a is shown in Fig. 3b and 3c.

[0090] Fig. 3b depicts a stack of containers 350a, 350b wherein each container 350a, 350b is equal to container 350.

[0091] The containers 350a, 350b are stacked and the central panels 312a, 312b of the respective ends 300a, 300b are substantially parallel (±2.0 °).

[0092] The lower surfaces 385a, 385b of the containers 350a, 350b may be substantially parallel (±2.0 °).

[0093] The stabilizing bead 312b of an end 300b of a container 350b may contact the lower surface 385a of another container 350a, when the containers 350a, 350b are stacked. Alternatively or additionally, the tab 340b of an end 300b of a container 350b may contact the lower surface 385a of another container 350a, when the containers 350a, 350b are stacked.

[0098] The extension sPB of the stabilizing bead 313a, 313b may be lower or equal to the extension sT of the tab 340a, 340b in the positive z-direction.

[0099] Fig. 4a depicts a container 450 that comprises an end 400 and a container body (not shown in Fig. 4a) analogous to e.g. container body 360a comprised by container 350a.

[0100] The end 400 comprises a central panel 412 that defines an x-y-plane. A stabilizing bead 413 is formed in the end 400, e.g. in the central panel 412. Further, a depression 414 is formed in the end 400, preferably in the central panel 412. The stabilizing bead 413 may have a basic c-shape. The stabilizing bead 413 may not fully surround a portion of the central panel in the x-y-plane.

[0101] A tab 440 comprising a front portion 441 and a rear portion 442 is attached to the end 400, specifically to the central panel 412, via a rivet 416.

[0102] The rear portion 442 of the tab 440 partially covers the depression 414 such that a consumer may reach the rear portion 442 of the tab 440 by moving a portion of the finger into the depression 414 and at least partially below the rear portion 442 of the tab 440.

[0103] Preferably, the depression 414 is not (fully) surrounded by the stabilizing bead 413.

[0104] A score line 418 is formed in an outer portion of the end 400, e.g. in the central plane 412, and surrounds a (large) portion of the end 400, e.g. the central plane 412.

[0105] The end 400 is seamed to the container body via curl 430 of the end 400.

[0106] The end 400 has a basic triangular shape in the x-y-plane.

[0107] Fig. 4b shows the end 400 in a top view. Further ends 400 are indicated below the shown end 400, wherein the ends 400 below the shown end 400 are rotated by 120 ° in the x-y-plane relative to the next end 400 as will be more detailed described with reference to Fig. 4c. A cross section C-C is indicated in Fig. 4b.

[0108] In Fig. 4c a stack of ends 400a-e is shown in the cross sectional view C-C indicated in Fig. 4b. Five ends 400 as ends 400a, 400b, 400c, 400d, and 400e are stacked. The end 400a has the same orientation in the x-y-plane as the end 400 shown in Fig. 4b.

[0109] Each end 400a-e is rotated by 120 ° in the x-y-plane relative to the preceding end 400a-e in the stack. E.g. end 400b is rotated by 120 ° in the x-y-plane relative to the end 400a and end 400c is rotated by 120 ° in the x-y-plane relative to the end 400b in the x-y-plane. Other ends 400d-e are orientated in the x-y-plane analogously. Thus, end 400c is rotated by 240 ° in the x-y-plane relative to the end 400a and e.g. end 400d has the same orientation in the x-y-plane as end 400a.

[0110] Each of the ends 400a-e comprises a central panel 412a-e, a stabilizing bead 413a-e, a depression 414a-e and a tab 440a-e. The central panels 412a-e of the stack of ends 400a-e are (substantially) parallel. Thereby, the stack of ends 400a-e shows an enhanced stability.

[0111] Fig. 4d depicts three stacked ends 400a-c, wherein each of the ends 400a-c is an end 400 as described above.

[0112] The tab 440a-c of the ends 400a-c may have an extension sT in the positive z-direction between 1.4 mm and 2.5 mm, preferably between 1.7 mm and 2.2 mm, more preferably between 1.8 mm and 2.0 mm.

Specifically, the depression 414a-c has an extension sFH of about 1.25 mm in the negative z-direction.

[0115] The extension sPB of the stabilizing bead 413a-c in the positive z-direction may be lower or equal to the extension sT of the tab 413a-c in the positive z-direction.

[0116] In the stack 400a-c, the stabilizing bead 413b of the end 400b may contact the end 400a, specifically the central panel 412a. The tab 440b of the end 400b may contact the end 400a, specifically the central panel 412a. The tab 440c of the end 400c may contact the end 400b, preferably the central panel 412b. The tab 440c of the End 400c may contact the end 400b, e.g. the central panel 412b.

[0117] Fig. 5a depicts a container 550 comprising an end 500 and a container body (not shown in Fig. 5a). The end 500 is seamed to the container body for closing the container 550 via a curl 530 of the end 500.

[0118] The end 500 comprises a central panel 512 that defines an x-y-plane. In the end 500, e.g. in the central panel 512, a stabilizing bead 513 is formed and the bead 513 extends in a positive z-direction, wherein the z-direction is perpendicular to the x-y-plane. Further, a depression 514 is formed in the end 500, preferably in the central panel 512, that extends in the negative z-direction.

[0119] End 500 comprises a tab 540 with a front portion 541 and a rear portion 542. The tab 540 is attached to the end 500, specifically to the central plane 512, via a rivet 516. The Depression 514 is partially overlapped by a portion of the tab 540, specifically by the rear portion 542 of the tab 540. The front portion 541 of the tab 540 may break a score line 518 that is located close to the outer edge of the end 500, when the tab 540 is pivoted about the rivet 516 by lifting the rear portion 542 of the tab 540.

[0120] The stabilizing bead 513 (fully) surrounds a portion of the central panel 512. The depression 514 may be positioned outside the surrounded portion of the central panel 512. The depression 514 may not be surrounded by the stabilizing bead 513.

[0121] The stabilizing bead 513 may have a basic oval shape.

[0122] The end 500 may have a basic oval shape.

[0123] Fig. 5b shows the end 500 in a top view, wherein a further end 500 is indicated below the end 500. Further, a cross section D-D is indicated in Fig. 5b.

[0124] Fig. 5c depicts a stack of ends 500a-e comprising several ends 500 as ends 500a, 500b, 500c, 500d and 500e.

[0125] In the stack of ends 500a-e, the ends 500a-e are each rotated by 180 ° in the x-y-plane relative to the next end 500 in the stack 500a-e. For example, end 500a has the same orientation as end 500 as shown in Fig. 5b. Compared to end 500a, end 500b is rotated by 180 ° in the x-y-plane and positioned below end 500a. Other ends of the stack 500a-e are positioned and orientated similarly.

[0126] Each of the ends 500a-e comprises a tab 540a-e. Each of the ends 500a-e further comprises a central panel 512a-e, a stabilizing bead 513a-e and a depression 514a-e.

[0127] In Fig. 5d a stack of ends 500a and 500b is depicted.

[0128] The tab 540a-b of ends 500a-b may have an extension sT in the positive z-direction between 1.4 mm and 2.5 mm, preferably between 1.7 mm and 2.2 mm, more preferably between 1.8 mm and 2.0 mm. Specifically, the tab 540a-b has an extension sT of about 1.95 mm in the positive z-direction.

[0129] The depression 514a-b of ends 500a-b may have an extension sFH in the negative z-direction between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.5 mm, more preferably between 1.2 mm and 1.5 mm. Specifically, the depression 514a-b has an extension sFH of about 1.25 mm in the negative z-direction.

[0130] The stabilizing bead 513a-b of ends 500a-b may have an extension sPB in the positive z-direction between 0.4 mm and 2.5 mm, preferably between 0.5 mm and 1.5 mm, more preferably between 0.6 mm and 1.0 mm. Specifically, the stabilizing bead 513a-b has an extension sPB of about 0.8 mm in the positive z-direction.

[0131] The extension sPB of the stabilizing bead 513a-b may be lower or equal to the extension sT of the tab 540a-b in the positive z-direction.

[0132] As can best be seen in Fig. 5c and 5d, when two ends 500a-b are stacked while the ends 500a-b are rotated by 180 ° in the x-y-plane, the depression 514a-b of one of the ends 500a-b is not overlapped by the stabilizing bead 513b-a of the other one of the ends 500b-a such that the central panels 512a-b of the ends 500a-b are substantially parallel (±2.0 °).

[0133] With reference to Fig 5d, the depression 514a of the first end 500a in the stack of ends 500a-b may contact the second end 500b, preferably the central panel 512b, in the stack of ends 500a-b. Alternatively or additionally, the tab 540b of the second end 500b may contact the first end 500a, preferably the central panel 512a. Alternatively or additionally, the stabilizing bead 513b of the second end 500b may contact the first end 500a, specifically the central panel 512a.

The end 600a comprises a tab 640a having a front portion 641a and a rear portion 642a. The tab 640a is attached to the end 600a, specifically to the central panel 612a of the end 600a, via a rivet 616a.

[0137] A depression 614a is formed in the end 600a, preferably in the central panel 612a, and extends in the negative z-direction from the x-y-plane of the central panel 612a.

[0138] A score line 618a surrounds a (large) portion of the end 600a, preferably the central panel 612a, as a mechanically weakened portion described above.

[0139] A curl 630a is seamed to the container body 660a (see Fig. 6d) for attaching the end 600a to the container body 660a and to form a closed container 650a.

[0140] The end 600a has a basic oblonged rectangular shape. Two sides of the basic rectangular shape are longer, preferably at least two or three times longer, than the other two sides of the basic rectangular shape.

In the end 700, specifically in the central panel 712, a stabilizing bead 713 is formed and the bead 713 extends in a positive z-direction, wherein the z-direction is perpendicular to the x-y-plane. Further, a depression 714 is formed in the end 700, e.g. in the central panel 712, that extends in the negative z-direction.

[0160] End 700 comprises a tab 740 with a front portion 741 and a rear portion 742. The tab 740 is attached to the end 700, e.g. to the central panel 712, via a rivet 716. The Depression 714 is partially overlapped by a portion of the tab 740, specifically by the rear portion 742 of the tab 740. The front portion 741 of the tab 740 may break a score line 718 as described above.

[0161] The stabilizing bead 713 (fully) surrounds a portion of the central panel 712. The depression 714 may be positioned outside the surrounded portion of the central panel 712. The depression 714 may not be surrounded by the stabilizing bead 713.

[0162] The stabilizing bead 713 may have a basic oval shape with two elongated sides that may be parallel over a distance of at least 10 mm.

[0163] The end 700 may have a basic oval shape with two elongated sides that may be parallel over a distance of at least 10 mm.

[0164] Fig. 7b shows the end 700 in a top view. A further end 700 is indicated below the end 700. A cross section G-G is indicated in Fig. 7b.

[0165] Fig. 7c depicts a stack of ends 700a-e. Each of the ends 700a-e may be an end 700 as described above.

[0166] In the stack of ends 700a-e, the ends 700a-e are each rotated by 180 ° in the x-y-plane relative to the next end 700 in the stack 700a-e. For example, end 700a has the same orientation as end 700 as shown in Fig. 7b. End 700b is rotated by 180 ° in the x-y-plane relative to end 700a and positioned below end 700a. Other ends of the stack 700a-e are positioned and orientated similarly.

[0167] Each of the ends 700a-e comprises a tab 740a-e, a central panel 712a-e, a stabilizing bead 713a-e and a depression 714a-e.
