Description

W. J. JESTER REVOLVABLE TRAY April 4, 1961 2 Sheets-Sheet 2 Filed July 2, 1959 WZY yfNVENTOR. 076M Arrow/5y This invention relates to 'revolvable trays of the Lazy "Susan *type and is particularly "directed :to "a novel corn partrnente'd tray construction including ajlid :shiftably mounted so 'that in one position it is adapted to "tightly seal the contents. of ithe tray 'and in Lanother;posi tion is supported a j substantial distance above the tray, providing a re'ady access to the contents :of thetray compartments. .':It is becoming increasingly common practice for in-' clividuals'and even -entire"families 'to supplement their daily diets by means of food supplement tabletsyvitamin pills, or' the like, It iscustomarily"recommended that these tablets or 'pills be-taken regularly at meal f-times.

There are additional "numbers of peoplerequired to take mineral capsules, brother-preparations at meale various times. V "The principal object ofthepresent invention isito pro- Patented Apr. .4, 1961 c --2 7 mostends of the partitions when the lid isclam'ped in its closed position 'over the tray. Thelid is also provided yvithaperipheral lip adapted to receive in nested engagethem a similarlip formed in theouter wall of thetray. These lips.provide a' double seal "around the periphery of the tray. Thus, when the lid is clampedjin its closed yi'de'means for automatically aligning the groovesin the vide a novel tray particularly adapted to' be'pla'ced on a fiining table, or the like, forfstoring food supplement tablets, vitamin "pills, mineral capsules, and "the like;

i More particularly, the present invention contemplates a revolvable tray of the Lazy Susan type-having? plurality of'indiiiidualcompartments adapted toreceive'and maintain 'inseparate groups large numbers of "tablets,*pills', of capsules. i

further-"object of the 'present {invention is to provide a :tray unit including a movably 'mounted lid adapted to tightlyseal the pills or tablets carried by the tray to protect them against contamination -or deterioration. The support for' the lid is constructed so that th'e lid-can be shifted and'held in a position inlwhich it is spaced'a substantial distance above the tray so that the contents of the tray can readily be removed. V

@ne advantage of the present tray construction is that it provides an attractive means to store "food supplement tablets :and other pills right at the point where they are normally consumed; i.e., the dining room table. 'Thus, the present tray completely eliminates the need for maintaining a number of unsightly bottles or boxes right in thedining area.

Another advantage ofthe"present invention is that the lid member is an integral part of the tray construction and is never completely disengaged'from the tray unit even when the tray contents are exposed. Thus, there is no possibility thatthe lid can become misplaced or accidentally dropped and-broken. i V

A still 'furtheradvant-age of the-present tray'unit'is that it is of extremely simple construction comprising only three elementsj' a base member for rotatably supporting atray and:a.lid.

More particularly, in a preferred embodiment of :the invention, a tray isrotatably supported on a base member. The tray is provided with a plurality of generally radialpartitions dividingthe trayinto a number of compartments. .A lid member is mounted above the tray and is both rotatably and .telescopically mounted upon .the base.. The lid member includes .radial grooves corresponding in number to the partitions of the tray. These radial grooves are adapted to tightly receivethe upperpositionythe contents. of the various compartments of the'tr'ay are notv only sealed from the atmosphere, but

jare also sealedfrom one another. 1 "One of the ,objects of thepresent invention is toprofingers to rotate the tray until the tray partitions are brought into properalignment with the lid grooves. The se"-and-'ot her objects and advantages'of the present invention will be more "readily apparent from a further considerationflof the following detailed description of the drawings illustrating -a preferred embodiment of the invention. i ll-n the drawings: I

As is shown in Figure l, a preferred form of tray unit :10 constructed in accordance with the principles of the present invention comprises a base member 11, a compartmented tray member 12 rotatably supported on base 11, and :a lid member .13 rotatably and telescopically mounted on base member 11. The tray member 12 is adapted 'to hold food supplement tablets, pills, capsules, or-the like, while lid'13 is adapted to be supported in a closed position, such as shown in Figure 2 to form a sealed container for these items or is adapted to be supportedinan elevated position, such as is shown in Figure 1 providing ready access to the contents of the tray compartments. More ,particularly, as is best shown in Figures 1, 2, and 3, base member 11 is formed of any suitable material, such as molded plastic, ceramic, metal or the like. Base member 11 comprises a flared pedestal portion 14 having an upwardly facing shoulder 15 surrounding a hollow sleeve llti which extends upwardly beyond the shoulder. Sleeve 16 is press-fit or otherwise firmly mounted withinan opening in basemember 11. The sleeve is provided "with a pin receiving groove 17. This groove extends vertically from the uppermost edge 18 of the sleeve downwardly to a point above shoulder 15. The groove includes a horizontal portion 20 terminating in a retaining recess 21. The upper edge 18 of the sleeve is provided with two spaced pin retaining recesses 22.

Tray member. 12, as is best shown in Figures 1 and 2, is formed of any suitable material such as molded plastic or ceramic and is generally round in configuration. The

tray includes a vertical peripheral wall .23 having an in for receiving the bottom edge of lid 13. The tray member also includes an inner cylindrical sleeve portion 27 adapted to telescopically receive sleeve section 16 of the base member. Sleeve 27 of the tray terminates in a bottom shoulder 28 adapted for rotatable'enga'gement with shoulder 15 of the base section. 1

Tray member 12 is further provided with a plurality 'of spaced

radial partitions

30, 31, 32, 33, 34 and 35. These partitions extend outwardly from inner sleeve 27 to outer vertical wall 23, are .of a height substantially greater than the height of the wall 23, and are effective to divide the tray into six compartments. As is best shown in Figures 1 and 3, the innermost end of each of the partitions 30-35 is preferably relieved as at 36 to forman upwardly sloping camming notch adapted to cooperatively engage a guide finger 37 associated with lid member 13.

Lid member 13 is also formed of any suitable material, such as molded plastic, and is-of a generally inverted dish shape including a peripheral depending wall 38 adapted to snugly fit around upstanding lip 24 formed on wall 23 of the tray member. Lid member 13, as is best shown in Figures 1, 2 and 4, further includes an integral knob portion 40 disposed on the upper surface of the lid. The

lid also includes a depending center stem 41 adapted to be telescopically received within sleeve 16 of the base member. Stem 41 carries a radially extending locking pin 42 spacedupwardly from the lower end of the stem, the pin being adapted to be received within slot 17 and to rest upon retaining recesses 22 formed on the upper shoulder of the sleeve.

Lid member 13 also carries one or more downwardly facing guide fingers 37. Each of these guide fingers includes two downwardly sloping, angulated cam faces 43 forming a downwardly projecting V adapted to enter the space between the adjacent partitions; e.g., the space 44 between partitions 30-35 of the tray member. Each of the guide fingers 37 also includes two vertical parallel side edges 45 spaced apart substantially the same distance as the innermost portions of adjacent partitions.

The lid member 13 further includes a central sleeve like portion 46 which, as is shown in Figure 2, is of the same radius as sleeve member 27 of tray member 12 so that when the lid is lowered to its closed position, as is shown in Figure 2, the lowermost rim 47 of sleeve 46 abuts the uppermost edge of sleeve 27. As is best shown in Figure 4, a plurality of radially extending downwardly opening grooves 54 extend between sleeve 46 of the lid and peripheral wall 38. These grooves correspond in number and in spacing to the partitions 30-35 of the tray member 12. Each of the grooves 54 is adapted to receive the upper rim of the adjacent partition when the lid is in the closed position, as shown in Figure 2.

In use, the compartments in the tray member 12 are filled with the desired food supplement tablets, pills, capsules, or the like, the partitions being effective to maintain the various types of tablets separate from one another. While the compartments are being filled, the lid is supported in the position shown in Figure 1 with pin 42 residing in engagement with one of the notches 22 formed on the upper edge of sleeve 16 while stem 41 is telescopically received within base sleeve 16. As is shown in Figure l, the lid when supported in this position is spaced a substantial distance above the tray member allowing ready access to the tray. The lid is also supported in this uppermost position when the tablets, or the like, are to be removed from the tray compartments. 7

The tray unit is preferably placed upon a dining room table and the various people at the table can easily reach the particular tablets desired by rotating the tray about sleeve 16. After the compartments have been filled, or the desired contents withdrawn, the user rotates knob 40 to bring pin 42 into registry with vertical groove 17. Thereafter the lid is lowered. Assuming that the 4 partitions 30-35 of the tray are not in alignment with the downwardly facing grooves 54 of the lid, one of the angulated camming faces 43 of guide finger 37 engages one of the angulated notches 36 of the partitions 30-35 in the manner shown in Figure 5. Thereafter as the lid is lowered further the cooperative engagement of the guide finger and partitions causes the tray member to rotate until the corresponding partitions and webs are aligned and vertical side edges 45 of the guide member pass between the opposed walls of the adjacent partitions as is shown in Figure 6.

With the lid in its closed position, the upper edges of each of the divider partitions is received within one of the grooves 54 of the lid. Also, the peripheral wall 38 of the lid is in engagement with the lip 24 of the tray member and the shoulders. of

sleeve members

27 and 46 are in abutment. Thus the lid not only effectively seals the compartments from the outside atmosphere, but also each of'the compartments is sealed from the adjacent compartments. When the lid is completely lowered to the position shown in Figure 2, the lid is again rotated slightly (together with the tray) to force pin 42 into horizontal leg 20 of groove 17 and finally into the retaining notch, or recess, 21 at the end of this leg. The lid member preferably is slightly resilient so that it forces pin 42 upwardly slightly, into the recess locking the lid firmly in place.

To again raise the lid, the lid is first pressed downwardly then is rotated to bring pin 42 into registry with the vertical portion of slot 17. Thereafter the lid is raised to disengage pin 42 from slot 17. Finally the lid is again rotated slightly until pin 42 is brought to rest in one of the supporting notches 22 formed on the upper edge of sleeve 16. The lid can be released and is selfsupported in this position spaced a substantial distance above the tray to provide ready access to the contents of the tray.
