연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

What is claimed is: 1. In a plastic storage container including a base panel for enclosing the bottom portion of said container, said base panel including an upper surface, a lower surface and a perimeter, an integrally formed side wall extending upwardly from said upper surface of said base panel perimeter defining said container, the improvement comprising: said side wall tapering outwardly as it extends upwardly and sized to fit within another like constructed container in a nested arrangement, said lower surface of said base panel including a plurality of integrally formed sockets each constructed and arranged to accept and retain a spherical roller so that said spherical roller is free to rotate and protrudes below said bottom surface of said base panel, each said socket including a cup portion and a flange portion, wherein said flange portion extends around the perimeter of said spherical roller, said flange including an inner surface and an outer surface; whereby a plurality of like constructed containers may be stored or shipped in a nested arrangement with said spherical rollers assembled to said containers and whereby said storage container may be rolled in any direction along a substantially smooth surface on said plurality of spherical roller assemblies. 2. The plastic storage container as described in claim 1 wherein said cup portion is conjugately shaped with respect to said spherical roller. 3. The plastic storage container as described in claim 1 wherein said cup portion includes at least one support bearing for reducing friction between said spherical roller and said cup portion. 4. The plastic storage container as described in claim 1 wherein said outer flange surface includes a holding groove extending therearound, wherein said holding groove is constructed and arranged to cooperate with a retaining ring to retain said spherical roller within said socket. 5. The plastic storage container as described in claim 1 wherein said side walls include an upper portion, wherein said upper portion includes an integrally formed handrail, wherein said handrail forms an inverted U-shaped channel extending around the perimeter of said storage container. 6. The plastic storage container as described in claim 1 including a lid, wherein said lid is constructed and arranged to cooperate with said storage container to enclose an internal cavity within said container. 7. The plastic storage container as described in claim 3 wherein each said cup portion includes a plurality of said support bearings, wherein said plurality of support bearings are constructed and arranged to scrape debris from said spherical roller. 8. The plastic storage container as described in claim 4 wherein said retaining ring is constructed and arranged for coupling engagement with said socket flange to retain said spherical bearing within said socket. 9. The plastic storage container as described in claim 8 wherein said retaining ring includes an outer surface and an inner surface, wherein said inner surface includes a holding groove, wherein said retaining ring holding groove is positioned to cooperate with said flange holding groove to retain said spherical roller; whereby said retaining ring may be assembled to said socket without additional fasteners or tools. 10. The plastic storage container as described in claim 5 wherein said handrail includes a plurality of integrally formed strengthening ribs for adding strength and rigidity to said storage container. 11. The plastic storage container as described in claim 5 wherein said handrail includes a at least two integrally formed handholds for improved gripping and lifting of said storage containers. 12. The plastic storage container as described in claim 5 wherein said handrail is constructed and arranged to cooperate with at least one snap-in lid latch member for mechanically and releasably securing a lid to said storage container. 13. The plastic storage container as described in claim 12 wherein said latch member is pivotally mounted to move between a latched position wherein said latch member is brought into a coupling engagement with said lid resulting in a mechanically secure connection between said storage container and said lid and an unlatched position wherein said lid is freely removable. 14. The plastic storage container as described in claim 6 wherein said lid includes a cover panel for enclosing the top portion of said lid, wherein said cover panel includes an upper surface, a lower surface and a perimeter, wherein a plurality of integrally formed side walls extend downwardly from said cover panel perimeter terminating in an outwardly extending flange, said flange including an inner perimeter and an outer perimeter, wherein an integrally formed depending wall extends downwardly from said outer perimeter of said flange, whereby said flange and said depending wall are constructed and arranged to cooperate with said handrail in an overlapping fashion. 15. The plastic storage container as described in claim 14 wherein a plurality of tabs extend downwardly from said inner perimeter of said flange, wherein said tabs cooperate with said container side walls to prevent inward bowing or flexing thereof. 16. The plastic storage container as described in claim 14 wherein said upper surface of said cover panel is constructed and arranged to cooperate with a base panel and plurality of roller assemblies to permit an axially aligned stacked arrangement of at least two storage containers. 17. The plastic storage container as described in claim 16 wherein said upper surface of said cover panel includes a generally rectangular channel, wherein said channel is constructed and arranged to provide clearance for said plurality of spherical roller assemblies, whereby an inner portion and an outer portion of said cover panel provides support for said base panel to provide a stable axially aligned stacked arrangement of at least two storage containers.
