Abstract
Abstract The invention concerns a tray blank, especially for eggs, having one or more upwardly extending projections, the diameter of each of said projections decreases in the upward direction, the lateral wall of each projection together with other wall sections adjacent to the projection comprising walls defining cell-shaped, upwardly open compartments adjoining the projection and intended to receive eggs. The projection is formed with an open projection which is slit downwardly from the top, starting from the upper, free edge of the wall of the projection, the wall sections defined by the slits continuing downwardly into the cell-shaped compartments and are formed as resilient surfaces supporting the eggs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
217 words
A tray blank especially for eggs comprising an egg carrier section and a cover, said carrier section having a plurality of egg-receiving compartments, each of said compartments being in part defined by a projection extending upwardly from the bottom of said carrier section, each projection having an open top, each projection having lateral wall portions, each lateral wall portion having an upper free edge at said open top, at least two slits in each projection, said slits extending downwardly from said upper free edge, said slits defining the lateral extent of said wall portions at and adjacent said upper free edge, each wall portion extending downwardly beyond said slits into a compartment, said wall portion being resilient due to the presence of said slits, said slits being free of engagement with said cover when said cover is in its closed position, said slits also being free when said cover is in its closed position to become reduced in size due to flexing of said wall portions, said wall portions in part defining an egg-receiving compartment only on one side of said wall portions, and the opposite side of said wall portions in part defining a space at all times free of eggs, whereby said wall portions may at all times give to support eggs of different sizes.

A tray blank especially for eggs comprising an egg carrier section and a cover, said carrier section having a plurality of egg-receiving compartments, each of said compartments being in part defined by a projection extending upwardly from the bottom of said carrier section, each projection having an open top, each projection having lateral wall portions, each lateral wall portion having an upper free edge at said open top, at least two slits in each projection, said slits extending downwardly from said upper free edge, said slits defining the lateral extent of said wall portions at and adjacent said upper free edge, each wall portion extending downwardly beyond said slits into a compartment, said wall portion being resilient due to the presence of said slits, said slits being free of engagement with said cover when said cover is in its closed position, said slits also being free when said cover is in its closed position to become reduced in size due to flexing of said wall portions, said wall portions in part defining an egg-receiving compartment only on one side of said wall portions, and the opposite side of said wall portions in part defining a space at all times free of eggs, whereby said wall portions may at all times give to support eggs of different sizes.
Claim 3
Dependent Claim
25 words
A tray blank according to claim 1 in which said slits are arranged in two planes arranged at substantially a right angle to each other.
Claim 4
Dependent Claim

A tray blank according to claim 1 in which said wall portion also curves inwardly toward the compartment to resiliently support an egg.
Claim 5
Dependent Claim
30 words
A tray blank according to claim 1 in which each compartment is also in part defined by additional walls, said additional walls being of lesser vertical extent than said projections.
Claim 6
Dependent Claim
25 words
A tray blank according to claim 4 in which said additional walls lie below said slits each in the same plane as its associated slit.
