Referring to the drawings in more detail:
The reference numeral 1 generally indicates a one-piece container or receptacle preferably molded of snythetic resin and comprising downwardly and inwardly converging side walls 2 and end walls 3 joined together and adapted to telescope ywithin each other for nesting as best illustrated in FIG. 2. The containers 1 each include a bottom wall 4 having spaced apart longitudinally extending ribs 5 formed integrally therewith and an upwardly open top 6 defined by top edges 7 and 8, respectively, of the side and end walls 2 and 3. The top edges 7 and 8 form a continuous four-cornered lip 9 integral with and extending outwardly from the container forming a substantially flat horizontal upper portion 10 and a downwardly extendi ing end flange 11.
caster wheels supported in spaced apart positions thereon C t in an manner which minimizes local bending in the l-id and thereby increases the life thereof; and to provide such a container assembly which is easily manufactured and rugged and convenient in use.
Other objects and advantages of this invention will become apparent from the following description taken in connection lwith the accompanying drawings wherein are set forth-by way of illustration and example certain embodiments of thisinvention.
FIG. l -is a perspective view showing several containers J in stacked condition with lids` therebetween, the stack being supported by an additional caster 'lid `for ease of movement.
FIG. 2 is a vertical cross-sectional View through three containers in nested positions.
FIG. 3 is a vert-ical cross-sectional View through a container and lid assembly showing the position assumed by the caster wheels when a caster lid is used as a cover.
FIG. 4 is a fragmentary cross-sectional view through a caster lid and container showing the container bottom A lid designated 12 is provided for the container 1 and has a central generally horizontally extending body portion 13 with an upper surface 14 and a lower surface 15. The lid 12 is also preferably constructed of molded synthetic resin in such manner that spaced apart integral parallel ribs 16 are alternately formed in the upper and lower surfaces 14 and 15 and are spaced apart for receiving the downward projecting portions of the container ribs, FIG. 4. In addition to the ribs 16, the lid 12 has upwardly extending or elevated corner joined` end and side ribs 17 and 18, respectively, which rise above the upper surface 14 adjacent and spaced slightly inwardly from a downwardly extending peripheral lip 19. The end and side ribs 17 and 18 form a cavity 20` for receiving the container bottom wall 4 and llower portions of the side and end walls 2 and 3 of an upper container, The cavity 20 is of a size for snugly receiving the bottom of the container without interfering with the cooperative engagement between the respective ribs 5 and 16 whereby when a container is resting upon the top surface of a lid, lateral relative displacement is prevented and separation can occur only by vertical separation.
The peripheral lip 1,9 on the lid includes a horizontal portion 21 and vertical portion Z2 which respectively engage the horizontal portion 10 and the downwardly extending flange 11 of the container when the lid is in top covering position. IOne end 23 (FIG. 7) of the lid 12 has a horizontal lip portion 24 projecting inwardly from the bottom edge of the vertical portion 22. The lip portion 24 is adapted for engagement with the bottom of the downwardly extending end ange 11 of the container to prevent vertical separation therebetween unless the lid is rst tilted upwardly from the container end 2S (FIG. 3) opposite 'the end 23 and then displaced horizontally toward the end 23 to effect disengagement between the lip portion 24 and the end flange 11.
The end 25 has a hasp member 26 pivotally fastened thereto and a correspondingly positioned latch member 27 is fixed to the adjacent end wall 3 of the container. The hasp member curved inwardly beneath the end 25 for engagement with the latch member whereby they lock together beneath the lid lip for preventing the removal of the lid since disengagement cannot then be effected at the opposite end 23. The latch member 27, in the illustrated example, comprises a planar tab 28 generally parallel to the end of Wall 3 and pivotally secured to a base plate 29 for rotation in a plan generally parallel to the end wall 3. When the tab 28 lis rotated downwardly while the hasp member 26 is in contact with the base plate 29, the hasp member becomes locked in position. An end opening 3() is provided in the tab 28 for receiving a padlock, wire seal, or the like (not shown) to prevent tampering. Rotation of the tab 28 upwardly permits the hasp member 26 to be pivoted outwardly and upwardly from the receptacle allowing release of the iid.
A plurality of caster wheels 31 are secured in spaced apar-t relation against the lid lower surface by means of a mounting plate 32 resting in suitable depressions or cavities 33 in the lid upper surface 14. The mounting plate 32 has a plurality of depending threaded studs 33 secured thereto and depending through bores 34 extending through the body portion 13 of the lid. The studs 33 also extend through the respective caster wheel plate 35 and receive suitable nuts 36 whereby the plate 35 is urged securely against the lid lower surface 15. By spacing the studs 33 a considerable distance apart, the stress transferred to the lid from the caster wheels is spread over a relatively large area and is thereby reduced in magnitude, greatly increasing the fatigue life of the lid body portion 13, particularly in the area adjacent the caster wheels.
It is apparent from the above that the respective lids 12, when the caster wheels 31 are secured thereto, may be used selectively as a lid for cover-ing a container 1 or as a truck for receiving a container and allowing wheeled movement thereof `over a oor surface 37. The cavity in the lid for receiving the bottom of a container also serves to permit modular stacking of several containers (FIG. 1). When the respective lids are locked into posit-ion on the several containers, the lack of easy separation bet-Ween the lids and containers helps insure against upsetting the stack during movement on the casters of the lowermost lid which supports the entire stack. When empty containers are nested as in FIG. 2, a stack thereof may also be moved on a Vlid in the same manner.
It is sometimes more convenient to dispense with one or more of the intermediate lids in a stack and yet be able to transport a plurality of containers simultaneously. To accomplish this outwardly projecting pairs of aligned spaced apart hinges 38 are provided on each side of the container as illustrated in FIGS. 8, 9 and 10. The hinges 38 may be formed integrally with the molded container or suitably secured thereto, for example, in the same manner as the caster wheels 31. A rod support 39 is pivotally mounted on the respective pairs of hinges 38 for selective pivotal movement from a position resting on the top edge 7 of the container (FIG. 8) to a position entirely beneath the top edge 7 (FIG. 9). The rod supports 39 are suitably bent so that an intermediate portion 40 can assume the alternate positions of resting on the top edges 7 when folded up and against the side wall 2 when folded down. The rod supports, when in the top resting position, projeot toward the opposite side wall top edge and terminate in a downwardly offset protion 41 for receiving the bottom wall edge of an upper con-tainer, thereby preventing lateral displacement of the upper container with respect to the lower or supporting container and maintaining the upper container in a stacked condition -in absence of a lid 12. A connecting rod portion 42 of each rod support 39 extends between the spaced apart hinges 38 and may conveniently be used as a handle for lifting the container regardless of the position taken by the rod support 39. The rod supports, when folded down, do not interfere with the nesting of the containers.
FIGS. 11, 12 and 13 illustrate various positions in which the caster wheels may be placed on the body portion 13 of the lid 12. The desired position of the caster wheels 31 will, of course, cause variations in the particular configuration of the lid ribs 16 adjacent the caster wheels; however, this need not cause alteration of the ribs S of the container since the mounting plates 32 are recessed at or below the lowermost level of the lid body portion 13 and thus do not interference with the interlocking of the ribs 5 and ribs 16, FIG. 4.
It is to be understood that although certain forms of this invention have been illustrated and described, it is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the following claims.
