Definitions
- the invention relates to an end for a container, specifically to an easy open end comprising a pull-tab.
- 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.
- 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.
- a problem to be solved by the invention is to provide an end for a container that allows a transport, on e.g. a belt conveyor, with enhanced stability during the transport of the end.
- An end for a container may comprise a central panel, a tab, a depression and at least one bead.
- the central panel defines an x-y-plane and a z-direction is perpendicular to the x-y-plane.
- the tab is attached to the end, e.g. via a rivet.
- the tab is attached to the central panel.
- the tab comprises a front portion and a rear portion, and the tab extends in positive z-direction.
- the depression is formed in the end, preferably in the central panel of the end.
- the depression extends in the negative z-direction and is shaped and positioned to allow a human finger to reach at least partially below the rear portion of the tab.
- the at least one bead is shaped in the end, preferably in the central panel of the end.
- the bead extends in the negative z-direction.
- the depression and the bead are shaped and positioned such that when the end is positioned on a flat surface while the depression and the bead contact the flat surface, the x-y-plane defined by the central panel of the end is parallel ⁇ 2.0 ° to the flat surface.
- 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.
- the x-y-plane defined by the central panel is parallel ⁇ 1.5 °, more preferably ⁇ 1.0 °, most preferred ⁇ 0.5 °, to a flat surface when the end is positioned on the flat surface.

Description
- The invention relates to an end for a container, specifically to an easy open end comprising a pull-tab.
- 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.
- 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.
- In the manufacturing plant of such ends, semi-finished or finished ends are often transported on belt conveyors. The transport of known ends is often unstable such that already minor vibrations can cause the end to move into an unfavorable position on the conveyor or even fall off the conveyor, especially if the end comprises a depression partially below a pull-tab that is designed for facilitating access to the pull-tab.
- Customers, such as food producers, typically transport such ends on belt conveyors with flat surfaces as well during the packaging process and face the same difficulties as end manufacturers described above.
- A problem to be solved by the invention is to provide an end for a container that allows a transport, on e.g. a belt conveyor, with enhanced stability during the transport of the end.
- This problem is solved by an end (or a lid) for a container according to
claim 1, by a stack of at least two ends according to claim 12, by a container according to claim 13 or by a stack of at least two containers according to claim 15. - An end for a container may comprise a central panel, a tab, a depression and at least one bead.
- The central panel defines an x-y-plane and a z-direction is perpendicular to the x-y-plane.
- The tab is attached to the end, e.g. via a rivet. Preferably, the tab is attached to the central panel. The tab comprises a front portion and a rear portion, and the tab extends in positive z-direction.
- The depression is formed in the end, preferably in the central panel of the end. The depression extends in the negative z-direction and is shaped and positioned to allow a human finger to reach at least partially below the rear portion of the tab.
- The at least one bead is shaped in the end, preferably in the central panel of the end. The bead extends in the negative z-direction.
- The depression and the bead are shaped and positioned such that when the end is positioned on a flat surface while the depression and the bead contact the flat surface, the x-y-plane defined by the central panel of the end is parallel ±2.0 ° to the flat surface.
- Thereby, the transportability of the end is increased.
- 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.
- It is preferred that the x-y-plane defined by the central panel is parallel ±1.5 °, more preferably ±1.0 °, most preferred ±0.5 °, to a flat surface when the end is positioned on the flat surface.
- The flat surface may be a conveyor belt.
- 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.
- 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.
- 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.
- 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.
- Generally, when an extension of an element, e.g. extension of the tab, bead, (at least one) bulge, depression or second stabilizing 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.
- 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 bead, the bulge, the depression, the second stabilizing 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.
- It is preferred that the 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.
- The extension of the bead may be equal to the extension of the depression in the negative z-direction ±1.5 mm, preferably ±1.0 mm, more preferably ±0.5 mm, most preferably ±0.2 mm. It is especially preferred that the extension of the bead is substantially equal to the extension of the depression in the negative z-direction.

Fig. 1 shows anend 100 for a container. Theend 100 comprisescentral panel 112 and atab 140. Thetab 140 is attached to theend 100, especially to thecentral panel 112, via arivet 116 and thetab 140 comprises afront portion 141 and arear portion 142. - The
central panel 112 of theend 100 defines an x-y-plane. A z-direction is perpendicular to the x-y-plane. A stabilizingbead 113 is formed in theend 100, preferably in thecentral panel 112, and extends in the positive z-direction from the x-y-plane of thecentral panel 112. The stabilizingbead 113 is substantially c-shaped and not fully surrounds a portion of thecentral panel 112. Beads such as stabilizingbead 113 are formed to enhance mechanical stability of an end. - Further, the
end 100 comprises adepression 114 that is formed in theend 100, preferably in thecentral panel 112, and extends in the negative z-direction from the x-y-plane. Thedepression 114 has a basic circular shape and is positioned such that a portion of thetab 140, i.e. therear portion 142 of thetab 140, overlaps thedepression 114. The depression allows a consumer to reach therear portion 142 in a more convenient manner, when the consumer intends to lift therear portion 142 of thetab 140 in order to open theend 100. - A
first bulge 120 and asecond bulge 121 are formed in theend 100, preferably in thecentral panel 112 of theend 100. Thebulges first bulge 120 is located close to a first side of thetab 140 that extends from thefront portion 141 to therear portion 142. Thesecond bulge 121 is located close to a second side of thetab 140 that extends from thefront portion 141 to therear portion 142. The first side of thetab 140 and the second side of thetab 140 are opposite sides. - The
bulges tab 140 about therivet 116 in a plane parallel to the x-y-plane. Such a rotation of thetab 140 prior to lifting therear portion 142 of thetab 140 might cause thetab 140 to break since thefront portion 141 of thetab 140 can attack thecentral panel 112 at a position that is too far away from thescore line 118 as mechanically weakened portion of theend 100, preferably of thecentral panel 112. - The
