  • the hollow support shaft and the rotating dials 380 are mounted on an adjacent edge portion of lower dish 320 so as to mate with the toothed pin 340 to form the multi-dial combination lock mechanism.
  • the lid or cover 350 can optionally include a portion or tab (not illustrated) on the side opposite the slide mechanism that fits into recess or retainer (not illustrated) on an adjoining portion of lower dish 320 so as to prevent prying open of the lid from the side opposite the locking mechanism. While illustrated as having rotating dials 380 on the lower dish 320 and toothed pin 340 and slide mechanism 345 on the cover 350, it is also possible to have the rotating dial 380 portion of the lock on the cover 350 and the toothed pin 340 and sliding mechanism 345 portion of the lock on the lower dish 320.

  • Such walls 325 can also provide additional strength and rigidity to the lower dish 320.
  • the lower dish 320 can also optionally include a lip portion 330 on one or more sides to aid in handling of the dish.
  • An optional recess or retainer element as discussed above with respect to Figure 1 can be formed as part of lip portion 330 to engage a portion or tab on cover 350 to prevent prying open of the cover 350 from the side opposite the locking mechanism.

  • the materials used for the safety dish should have sufficient strength and stiffness to prevent the cover or lock from being "jimmied" open.
  • the disclosed combination lock will suffice for ordinary situations such as preventing theft from a common workplace lunchroom refrigerator, such locks are susceptible to defeat from a brute-force approach of trying all permutations or from inspection while in a dishwasher to discover the combination. For greater security, more secure locks should be used.
  • the safety dish comprises a dish with a base, side walls, and a first portion of a locking mechanism; and a cover for the dish, the cover dimensioned to engage a top of the side walls to enclose a food storage area, and the cover further comprising a second portion of the locking mechanism, wherein the first and second portions of the lock mechanism form a multi-dial combination lock, with one side of the lock mechanism comprising a toothed pin mounted on a sliding mechanism.
  • the first portion of the locking mechanism comprises a hollow support shaft with a C-shaped cross-section fixed to a side wall of the dish; and a plurality of rotating dials mounted to rotate on the hollow support shaft, with each dial having notch.
  • the second portion of the locking mechanism preferably comprises the toothed pin mounted on the sliding mechanism, wherein the second portion is positioned on the cover so as to allow the sliding mechanism to move the toothed pin into and out of the hollow support shaft of the first portion when the cover is engaged with the top of the side walls of the dish and the notches of the plurality of dials are aligned.
  • Variations of this embodiment include those wherein the sliding mechanism comprises a planar support; a linear slot formed in the planar support; an actuation element; and a support element joining the toothed pin to the actuation element through the linear slot.
  • Other variations may comprise corresponding tab and retaining elements on the cover and dish on a side of the safety dish opposite the locking mechanism.
  • the dish, cover and lock mechanism of these embodiments are formed from dishwasher-safe materials.

Abstract

La présente invention concerne un plat à sécurité formant un récipient alimentaire sûr et comportant un plat destiné à contenir un aliment, un couvercle destiné à renfermer le plat et l'aliment, et un mécanisme de verrouillage destiné à fixer le couvercle au plat en vue d'empêcher un accès non autorisé à l'aliment et/ou une altération de l'aliment. Une saisie correcte d'une combinaison est requise pour accéder au contenu alimentaire du récipient par le biais d'un mécanisme de verrouillage coulissant. Le plat à sécurité et le mécanisme de verrouillage sont de préférence fabriqués à partir de matériaux lavables au lave-vaisselle et transparents aux micro-ondes.
