Abstract
Provided is a multi-compartment tray having at least two compartments that are connected at the time of sale and then able to be split into separate, detached compartments by a user. The compartments are conjoined by a 3-dimensional wave-shaped perforation region. Each perforation wave includes a crest and a trough and perforation tabs are formed on at least some of the crests and troughs and form the point of interconnection between the compartments. In use, a user can apply leverage to the offset planes resulting in bending/snapping of the compartments relative to one another and causing the perforation break, thereby separating the compartments.
Claims13
A multi-compartment tray, comprising:
- a. first and second compartments conjoined along a first longitudinal axis and each of which contains an edge that extends along the first longitudinal axis and in a first plane;
- b. a perforation region that conjoins the first and second compartments and comprises:
- i. a plurality of first and second cut-away regions formed in the edges of the first and second compartments, respectively, wherein each first cut-away region is laterally spaced from every other first cut-away region along the first longitudinal axis, further wherein each second cut-away region is laterally spaced from every other second cut-away region along the first longitudinal axis, additionally wherein each of the plurality of first and second cut-away regions includes a perforation wave having a wave thickness;
- ii. a first plurality of perforation tabs joining the first and second compartments and extending in series along a second longitudinal axis that is parallel to and vertically offset from the first longitudinal axis, wherein each of the first plurality of perforation tabs has a first tab thickness, and wherein the first tab thickness is less than the wave thickness;
- and
- iii. a second plurality of perforation tabs joining the first and second compartments and extending in series along a third longitudinal axis that is parallel to and vertically offset from the first and second longitudinal axes, whereby the first and second plurality of perforation tabs provide enhanced rigidity to the multi-compartment tray and rotationally bending the first and second compartments relative to one another about the first longitudinal axis causes them to snap and break the first and second plurality of perforation tabs forming the connection between the first and second compartments, wherein each of the second plurality of perforation tabs has a second tab thickness, and wherein the second tab thickness is less than the wave thickness;
- wherein the perforation region is substantially sinusoidal and comprises a series of undulating crests and troughs to facilitate separating the first compartment from the second compartment by snapping and breaking the first plurality of perforation tabs and the second plurality of perforation tabs, wherein the perforation tabs are only arranged at the crests and troughs of the perforation region, wherein only one perforation tab is arranged at each of the crests or troughs such that the sole attachment between the first and second compartments is achieved through connection of the perforation tabs at the crests and troughs, and wherein the first and second cut-away regions are longitudinally aligned along the first longitudinal axis.
4 more elements
A multi-compartment tray, comprising:
- a. first and second compartments having first and second edges, respectively, that extend towards one another in a first plane;
- b. a wave-shaped perforation region arranged about a first longitudinal axis having a series of undulating crests and troughs that extend in series with respective tangents that extend in second and third planes, respectively, and are parallel to and laterally offset from the first plane and from each other, wherein at least some of the undulating crests and troughs comprise a perforation tab formed thereon that connect the first and second compartments, wherein the perforation tabs are only arranged at the crests and troughs of the perforation region, wherein only one perforation tab is arranged at each of the crests or troughs such that the sole attachment between the first and second compartments is achieved through connection of the perforation tabs at the crests and troughs, whereby rotationally bending the first and second compartments relative to one another about the first longitudinal axis causes them to snap and break the perforation tab forming a connection between the first and second compartments, wherein the wave-shaped perforation region has a wave thickness, and each of the perforation tabs has a tab thickness less than the wave thickness;
- wherein the perforation region is substantially sinusoidal to facilitate separating the first compartment from the second compartment by snapping and breaking each of the perforation tabs, and wherein the series of undulating crests and troughs is longitudinally aligned along the first longitudinal axis.
