DETAILED DESCRIPTION
(13) The embodiments described herein generally relate to nestable pallets formed from an upper deck and a lower deck. The upper deck can comprise a plurality of foot members that are reinforced by the lower deck. Various embodiments of the nestable pallet and methods for forming the same are described in more detail herein.
(14) Referring collectively to
(15) The upper deck 102 of the nestable pallet 100 can be configured to support goods above a surface. In some embodiments, the upper deck 102 can form a product support region 104 that provides a substantially planar surface for holding goods. The product support region 104 of the upper deck 102 can be demarcated by a perimeter 106. In some embodiments, the perimeter 106 can be configured to define a shape for the product support region 104. For example, the perimeter 106 can define a product support region 104 having a substantially rectangular shape. It is noted that the term nestable, as used herein, can mean configured for stacking in an interlocking fashion.
(16) Accordingly, the perimeter 106 can comprise a plurality of substantially linear edges. Specifically, the perimeter 106 can comprise a first edge 108, a second edge 110, a third edge 112, and a fourth edge 114. In some embodiments, the first edge 108 can be substantially parallel to the third edge 112. Likewise, the second edge 110 can be substantially parallel to the fourth edge 114. Each of the first edge 108, the second edge 110, the third edge 112, and the fourth edge 114 can intersect with another edge to form an intersection region 116. Each intersection region 116 can be characterized by an intersection angle .

(22) Each foot member 130 can comprise a base portion 140 for supporting the foot member 130 upon a surface. The base portion 140 of the foot member 130 can be offset downwardly from the product support region 104. Alternatively or additionally, the base portion 140 can be offset downwardly from the flared mouth 138 of the foot member 130. In some embodiments, the outer surface 134 of the foot member 130 can form a substantially planar surface at the base portion 140. Accordingly, the base portion 140 can be substantially parallel with the product support region 104. In some embodiments, the base portion 140 of the foot member 130 can be smaller than the flared mouth 138 of the foot member 130. For example, the body 136 of the foot member 130 can be tapered inward as the body 136 spans from the product support region 104 to the base portion 140 of the foot member 130. Accordingly, a substantially identically shaped foot member can be received by and nested within each foot member 130.
(23) In some embodiments, the body 136 of the foot member 130 can comprise a shank portion 142 for aiding in assembly of the nestable pallet 100. The shank portion 142 can be offset downwardly from the product support region 104. Additionally, the shank portion 142 can be offset upwardly from the base portion 140. In some embodiments, the foot member 130 can be substantially cylindrically shaped at the shank portion 142. Accordingly, the outer surface 134 of the foot member 130 can form a mounting feature 144 that projects outwardly, i.e., in a direction away from the nesting surface 132, at the shank portion 142.
(24) Referring still to

(26) Referring collectively to
(27) The support rim 208 can be configured to provide reinforcement of the foot member 130. In some embodiments, the support rim 208 can project away from the inner surface 204 of the foot strengthening orifice 202 and towards the foot member 130. Alternatively or additionally, the support rim 208 can be concentric to the foot member 130. The support rim 208 can be aligned with the inner surface 204 at a support angle . In some embodiments, the support angle can be substantially obtuse such as, for example, greater than about 200 in one embodiment, between about 300 and about 240 in another embodiment, or about 270 in a further embodiment. In some embodiments, the support rim 208 can contact the mounting feature 144 of the foot member 130. Accordingly, the support rim 208 can constrain motion of the foot member 130 to provide downward support, concentric support, or both to mitigate bending moments in the foot member 130.
(28) According to the embodiments described herein, the foot strengthening orifice 202 can comprise a plurality of stiffening members 210 each configured to strengthen the support rim 208. Each stiffening member 210 can be coupled to the inner surface 204 and the support rim 208. In some embodiments, the stiffening members 210 can extend along the inner surface 204 downwards to the support rim 208. Each stiffening member 210 can project away from the inner surface 204 to define a width of the stiffening member 210. The width of the stiffening member 210 proximate to the top edge 206 of the lower deck 200 can be relatively small compared to the width of the stiffening member 210 proximate to the support rim 208. For example, the width of the stiffening member 210 can increase as the stiffening member extends downwards to the support rim 208. In some embodiments, the stiffening member 210 can be shaped such that the width of the stiffening member 210 is largest at the support rim 208.
(29) Referring collectively to
(30) According to the embodiments described herein, the joining platform 212 and the outer rim 118 can cooperate to define a joining feature 216 that facilitates joining of the upper deck 102 and the lower deck 200. For example, the joining feature 216 can be configured to facilitate plastic welding of the outer rim 118 of the upper deck 102 to the joining platform 212. Accordingly, the upper deck 102 and the lower deck 200 can be joined with a plastic weld applied to the joining feature 216. In some embodiments, the joining feature 216 can define a recessed region with respect to the outer rim 118, the perimeter 214 of the lower deck 200, or both. For example, the joining feature 216 can be recessed by an offset distance 218 from an outer face of the outer rim 118. Alternatively or additionally, the joining feature 216 can be recessed by the offset distance 218 from the perimeter 214 of the lower deck 200. In some embodiments, the joining platform 212 can comprise a collar 220 that is configured to form at least a portion of the joining feature 216. The collar 220 can project upwards from the joining platform 212 and towards the upper deck 102. The collar 220 of the joining platform 212 can be recessed by the offset distance 218 from the perimeter 214 of the lower deck 200. Alternatively or additionally, the outer rim 118 of the upper deck 102 can comprise a collar 148 that is configured to form at least a portion of the joining feature 216. The collar 148 can project downwards from the outer rim 118 and towards the lower deck 200. The collar 148 of the outer rim 118 can be recessed by an offset distance 218 from the outer face of the outer rim 118.

(32) In some embodiments, the lower structural member 260 of the lower deck 200 can span between multiple foot strengthening orifices 202. For example, the perimeter 214 can comprise a plurality of substantially linear edges. Specifically, the perimeter 214 can comprise a first edge 230, a second edge 232, a third edge 234, and a fourth edge 236. In some embodiments, the first edge 230 can be substantially parallel to the third edge 234. Likewise, the second edge 232 can be substantially parallel to the fourth edge 236. Each of the first edge 230, the second edge 232, the third edge 234, and the fourth edge 236 can intersect with another edge to form an intersection region 238.
(33) Referring now to
(34) In further embodiments, the lower deck 200 can comprise a foot strengthening orifice 202 positioned substantially at the center 226 of the lower deck 200 and a foot strengthening orifice 202 positioned adjacent to an intersection region 238 of the lower deck 200. One or more of the lower structural members 260 can span from the foot strengthening orifice 202 positioned substantially at the center 226 to the foot strengthening orifice 202 positioned adjacent to the intersection region 238. In some embodiments, the lower structural members 260 can extend along a diagonal path between the foot strengthening orifice 202 positioned substantially at the center 226 and the foot strengthening orifice 202 positioned adjacent to the intersection region 238. In some embodiments, the diagonal path can substantially bisect the intersecting edges, i.e., the first edge 230 and the fourth edge 236.
