Abstract
Abstract This invention relates to a tray-like pallet made of stiff plastic material and suitable for use in the setting up of a stack of identical containers each having a top with an outline capable of providing support and different in area from the outline of the bottom thereof, the said pallet having on one face a plurality of non-interconnected projection means between a number of which the base of each container of a series of containers forming a single tier of the stack can be sufficiently confined to produce a stable stack, and having on the other face a plurality of projection means between a number of which the top of each container of a series of containers forming a lower tier of the stack also can be sufficiently confined to produce a stable stack, the pallet being in addition so formed that a plurality thereof are stackable when not in use.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
236 words
A tray-like pallet made of stiff plastic material and suitable for use in setting up a stack of identical containers each having a top with an outline capable of providing support and different in area from the outline of the bottom thereof, said pallet having a generally planar base, a plurality of noninterconnected projection means on one face, between a number of which the base of each container of a series of containers, forming a single tier of said stack, can be sufficiently confined to produce a stable stack, and having a plurality of projection means on the other face, between a number of which the top of each container of a series of containers, forming a lower tier of said stack can also be sufficiently confined to produce a stable stack, said projection means of said two faces being arranged with respect to one another in a manner such that the bottom of each of the upper containers in said stack and the cover of each of the underneath containers in said stack are in direct contact with said planar base of said pallet and that the bottoms and covers of the stacked containers are fully supported by said planar base and spaced from one another by the thickness of said planar base only and said pallet is also formed in a manner that a plurality of said pallets are stackable when not in use.
Claim 2
Dependent Claim
236 words
A tray-like pallet made of stiff plastic material and suitable for use in setting up a stack of identical containers each having a top with an outline capable of providing support and different in area from the outline of the bottom thereof, said pallet having a generally planar base, a plurality of noninterconnected projection means on one face, between a number of which the base of each container of a series of containers, forming a single tier of said stack, can be sufficiently confined to produce a stable stack, and having a plurality of projection means on the other face, between a number of which the top of each container of a series of containers, forming a lower tier of said stack can also be sufficiently confined to produce a stable stack, said projection means of said two faces being arranged with respect to one another in a manner such that the bottom of each of the upper containers in said stack and the cover of each of the underneath containers in said stack are in direct contact with said planar base of said pallet and that the bottoms and covers of the stacked containers are fully supported by said planar base and spaced from one another by the thickness of said planar base only and said pallet is also formed in a manner that a plurality of said pallets are stackable when not in use.
Claim 3
Dependent Claim
52 words
A pallet as claimed in claim 1, for the support of containers with tapered sides diverging towards the top, in which pallet the projections intended tO confine the bottoms of the containers are made of a height which is more than 15 percent of the height of the container to be confined.
Claim 4
Dependent Claim
54 words
A pallet as claimed in claim 1, for the support of containers with tapered sides diverging towards the top, in which pallet the projections intended to confine the bottoms of the containers are made of a height which is more than 20 to 50 percent of the height of the container to be confined.
Claim 5
Dependent Claim
26 words
A pallet as claimed in claim 2, in which the projections intended to confine the tops of the containers are 0.5 to 50 mm in height.
Claim 6
Dependent Claim
26 words
A pallet as claimed in claim 2, in which the projections intended to confine the tops of the containers are 3 to 10 mm in height.
Claim 7
Dependent Claim
19 words
A pallet as claimed in claim 1, of which the projections on either or both faces are resiliently deformable.
Claim 8
Dependent Claim
23 words
A pallet as claimed in claim 1, including orifice means arranged for air passage between tiers of containers when in a stack thereof.
Claim 9
Dependent Claim
20 words
A pallet as claimed in claim 7, in which said orifices are in the projections on either or both faces.
Claim 10
Dependent Claim
21 words
A pallet as claimed in claim 1, including stiffening portions between the projections intended to confine the tops of the containers.
Claim 11
Dependent Claim
16 words
A pallet as claimed in claim 1, made from a sheet of plastic material by deep-drawing.
Claim 12
Dependent Claim
27 words
A pallet as claimed in claim 10, having a deep-drawing ratio of width : height of any deformation produced by the deep-drawing operation of 5:1 to 1:5.
Claim 13
Dependent Claim
27 words
A pallet as claimed in claim 10, having a deep-drawing ratio of width : height of any deformation produced by the deep-drawing operation of 2.5:1 to 1:2.5.
Claim 14
Dependent Claim
23 words
A pallet as claimed in claim 1, including a continuous or interrupted peripheral rim turned out of the general plane of the pallet.
Claim 15
Dependent Claim
20 words
A pallet as claimed in claim 1, made of polystyrene or polyvinyl chloride or a copolymer of the corresponding monomers.
