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, Kafe, Webinar 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.

A beverage tray has a floor with peripheral, upstanding side and end walls for holding a plurality of containers of beverage, for example in six-packs. The floor has a plurality of downwardly projecting detents on its bottom surface for cooperation with the tops of beverage containers in a sub-adjacent tray to impede free sliding movement of an upper tray over the beverage containers in a sub-adjacent tray to enable stable stacking of the trays, while at the same time enabling the upper tray to be slid over the cans in the lower tray to remove the upper tray from a stack of trays. The detents are rectilinear and present spaced, opposed, parallel, straight detents that define detent sets surrounding bottle top receiving areas. The upper edge of the side wall is smoothly sinusoidally curved to define spaced, alternating upper side wall sections and recessed areas. The side wall has an inwardly inclined, planar outer side wall panel, and a plurality of flat pads are on the outer side wall panel for cooperation with automated machinery used in the handling of the tray.

A beverage tray as claimed in claim 1, wherein: said tray floor comprises a plurality of parallel, uniformly spaced apart, longitudinally and transversely extending orthogonally intersecting struts defining an open grid of rectangular configuration; and at least some of said detent means are formed on the underside of said struts. 3. A beverage tray as claimed in claim 2, wherein: said detent means include rectilinear formations supported by said transversely and longitudinally extending struts and having predetermined lengths in directions parallel to the plane of the tray floor and predetermined depths in a direction perpendicular to the plane of the tray floor. 4. A beverage tray as claimed in claim 3, wherein: said detent means comprise a plurality of detent sets distributed over the bottom surface of the tray floor, with a detent set disposed beneath each beverage container seating area, and each detent set defining a plurality of opposed pairs of parallel, straight detent sides. 5. A beverage tray as claimed in claim 4, wherein: said detent means include a first continuous, uninterrupted detent line extending along the longitudinal centerline of the tray bottom. 6. A beverage tray as claimed in claim 5, wherein: said detent means include second and third continuous, uninterrupted detent lines extending along respective transverse lines extending parallel to one another on opposite equally spaced sides of the transverse centerline of the tray. 7. A beverage tray as claimed in claim 6, wherein: said detent means includes a fourth line of spaced rectilinear detents extending along the transverse centerline of the tray, and fifth and sixth lines of spaced rectilinear detents lying along parallel transverse lines equidistantly spaced, respectively, on opposite sides of said second and third uninterrupted detent lines. 8. A beverage tray as claimed in claim 7, wherein: said lines of spaced detents and said lines of uninterrupted detents cooperate to define a plurality of said open channels free of detents extending transversely through opposite side edges of the tray from the longitudinal centerline thereof, and a plurality of said open channels free of detents extending longitudinally through opposite ends of the tray from the second and third lines, respectively, of uninterrupted detents. 9. A beverage tray as claimed in claim 8, wherein: the upper edges of the side walls are smoothly sinusoidally curved to define a plurality of alternating upper side wall sections and recessed areas. 10. A beverage tray as claimed in claim 9, wherein: the side walls comprise an inwardly inclined, planar outer side wall panel, and inner side wall panels on only the upper side wall sections, said inner side wall panels being perpendicular to the tray floor. 11. A beverage tray as claimed in claim 10, wherein: the upper edge of the end walls is recessed at opposite side edges thereof and across a substantial mid-portion, defining a pair of spaced apart upper end wall sections, said end wall having an inwardly inclined planar outer end wall panel, and inner end wall panels on only the upper end wall sections. 12. A beverage tray as claimed in claim 11, wherein: a plurality of spaced apart flat pads are on the outer side and end wall panels for machine handling of the tray. 13. A beverage tray as claimed in claim 12, wherein: one of said pads is located on an outer surface of each upper section of said side and end wall panels, said pads extending from a bottom edge of the respective side and end wall outer panel to a position spaced above the bottom of said recessed areas but below the top of said upper side and end wall sections. 14. A beverage tray as claimed in claim 13, wherein: a handle extends between the upper ends of said upper end wall sections. 15. A beverage tray for holding a quantity of containers of beverage, said tray comprising: a tray floor having transverse and longitudinal dimensions, side edges and end edges, a top surface and a bottom surface; upstanding side and end walls extending upwardly from the floor and around the periphery of the floor for confining beverage containers supported on the floor, upper edges of the side walls being smoothly sinusoidally curved to define a plurality of alternating upper side wall sections and recessed areas, and said side walls comprising an inwardly inclined, planar outer side wall panel extending from a bottom edge to the upper edge, and inner side wall panels on only the upper side wall sections, said inner side wall panels being perpendicular to the tray floor; and a plurality of raised, spaced apart flat pads on the outer side and end wall panels, extending substantially perpendicular to the plane of the tray floor and outwardly offset from the plane of their respective outer side and end wall panels, for machine handling of the tray. 16.
