Patent Description:
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.

Prior art considered during EPC examination are <CIT>), <CIT>), <CIT>), <CIT>), <CIT>) and <CIT>, published as <CIT>). The preamble part of claim <NUM> reads on the latter document <CIT>. This document discloses only one top view onto a lid and one section II-II which would not show all height relations of all depressions provided in the lid, e.g. more lines of potential sections are identified (see items <NUM>, <NUM>', pulling line <NUM> and 9a) that have no corresponding Figures to resolve the height/depth relations.

Mentioned containers are typically stacked in order to save precious room at store shelfs. The containers 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, still they are not stackable with a sufficient stability of the stack.

A problem to be solved by the invention is to provide an end for a container that allows stacking of a plurality of 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.

This problem is solved by a container according to claim <NUM> or by a stack of at least two containers according to claim <NUM>.

The container comprises 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.

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.

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 ±<NUM> ° 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.

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

Thereby, a stacking of (e.g. at least ten) containers 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.

The end may be an easy-open-end comprising the 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 <NUM> and <NUM>, preferably between <NUM> and <NUM>, more preferably between <NUM> and <NUM>, 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 <NUM> in the positive z-direction.

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.

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.

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.

The stabilizing bead may have an elongated shape. For example, the stabilizing bead may not be dome-shaped, especially may not be dome-shaped with a circular basic shape.

The stabilizing bead may extend over a length of at least <NUM>, at least <NUM>, at least <NUM>, at least <NUM>, or at least <NUM>, when the stabilizing bead has an elongated shape.

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

It is preferred that the stabilizing bead extends between <NUM> and <NUM>, preferably between <NUM> and <NUM>, more preferably between <NUM> and <NUM>, in a positive z-direction that is perpendicular to the x-y-plane of the central panel. Specifically, the stabilizing bead extends about <NUM> in the positive z-direction.

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.

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

It is especially preferred that (the central panels of) the two containers are parallel ±<NUM> °, ±<NUM> °, or even ±<NUM> °. Thereby, an increased stability of the stack is achieved.

Alternatively or additionally, the lower surfaces of the containers may be parallel ±<NUM> °, preferably ±<NUM> °, more preferably ±<NUM> °.

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.

The depression can be substantially circular shaped. The depression can have an area between <NUM><NUM> and <NUM><NUM>, preferably between <NUM><NUM> and <NUM><NUM>.

A stack of containers comprises at least two of any of the herein disclosed containers. The at least two containers are same containers, having at least the features of claim <NUM>.

The embodiments that have elements mentioned in claim <NUM> are real embodiments of the claimed invention of claims <NUM> or <NUM>.

Other embodiments that contradict to those claim <NUM> features or do not have such features are no real embodiments, but fall outside the scope of the claimed invention.

Embodiments of the invention are described in more detail with regard to the drawings. The description of the embodiments is not to be construed as to limit the scope defined by the claims. Same reference signs of the figures describe same elements.

<FIG> shows an end <NUM> for a container. The end <NUM> comprises central panel <NUM> and a tab <NUM>. The tab <NUM> is attached to the end <NUM>, especially to the central panel <NUM>, via a rivet <NUM> and the tab <NUM> comprises a front portion <NUM> and a rear portion <NUM>.

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

As an example, bead <NUM> as shown in <FIG> has an elongated shape.

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

A first bulge <NUM> and a second bulge <NUM> are formed in the end <NUM>, preferably in the central panel <NUM> of the end <NUM>. The bulges <NUM>, <NUM> extend from the x-y-plane in the positive z-direction. The first bulge <NUM> is located close to a first side of the tab <NUM> that extends from the front portion <NUM> to the rear portion <NUM>. The second bulge <NUM> is located close to a second side of the tab <NUM> that extends from the front portion <NUM> to the rear portion <NUM>. The first side of the tab <NUM> and the second side of the tab <NUM> are opposite sides.

The bulges <NUM>, <NUM> are provided to prevent a rotation of the tab <NUM> about the rivet <NUM> in a plane parallel to the x-y-plane. Such a rotation of the tab <NUM> prior to lifting the rear portion <NUM> of the tab <NUM> might cause the tab <NUM> to break since the front portion <NUM> of the tab <NUM> can attack the central panel <NUM> at a position that is too far away from the score line <NUM> as mechanically weakened portion of the end <NUM>, preferably of the central panel <NUM>.

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

At the outer edge of the end <NUM>, a curl <NUM> (implied in <FIG>) is positioned. The curl <NUM> of the end <NUM> can be used to attach the end <NUM> to a container body in order to produce a closed container. For example, the end <NUM> can be seamed to a container body via the curl <NUM>.

<FIG> shows a first end <NUM> in a top view, wherein a further end <NUM> is indicated below the first end <NUM> that is rotated by <NUM> ° in a x-y-plane as will be discussed in more detail below.

The end <NUM> may be equal to the end <NUM>. The end <NUM> comprises a central panel <NUM> that defines an x-y-plane. In the end <NUM>, specifically in the central panel <NUM>, a stabilizing bead <NUM> is formed and the bead <NUM> extends in a positive z-direction, wherein the z-direction is perpendicular to the x-y-plane. Further, a depression <NUM> is formed, preferably in the central panel <NUM>, and the depression <NUM> extends in the negative z-direction.

End <NUM> comprises a tab <NUM> with a front portion <NUM> and a rear portion <NUM>. The tab <NUM> is attached to the end <NUM>, e.g. to the central panel <NUM>, via a rivet <NUM>. The depression <NUM> is partially overlapped by a portion of the tab <NUM>, specifically by the rear portion <NUM> of the tab <NUM>. The front portion <NUM> of the tab <NUM> may break a score line <NUM> that is located close to the outer edge of the end <NUM>, when the tab <NUM> is pivoted about the rivet <NUM> by lifting the rear portion <NUM> of the tab <NUM>.

Optionally, in the proximity of the tab <NUM>, a first bulge <NUM> and a second bulge <NUM> are formed in the end <NUM>, preferably in the central plane <NUM>. The bulges <NUM>, <NUM> extend in the positive z-direction from the x-y-plane.
