(24) FIG. 1 is a perspective view of a first embodiment of the present invention with the lid 109 in an open position and containing a sliceable item of food 107. In this embodiment there is a food holder 101, having (i) a bottom 102 that includes a longitudinally disposed support surface 103, (ii) a pair of opposed side walls 104 coupled to the bottom 102, and (iii) a first end 105 and second end 106. The food holder 101 is configured to contain a sliceable item of food 107 on the support surface 103 and between the side walls 104; a dispensing opening 108 is located at the first end 105 of the food holder 101. Coupled to food holder 101 is the lid 109. In this embodiment, the lid 109 is rotatably mounted over the food holder 101, and it has an open position and a closed position; an end cap 110 having an upper edge 111 is coupled to the lid 109 at a location proximate to the first end 105, the end cap 110 oriented to cover the dispensing opening 108 when the lid 109 is in the closed position. The end cap 110 further has a lower edge 112 opposite the upper edge 111, the lower edge 112 configured to slice the sliceable item of food 107 when the lid 109 is moved from the open position to the closed position. Components of this and other embodiments may be made of any suitable material. Suitable materials may be polymeric, composite polymeric, ceramic, metal or other materials that have sufficient rigidity and flexibility to perform the requirements described herein.
(25) FIG. 2 is a cross sectional side view of the embodiment of FIG. 1 with the lid 109 in the closed position. This figure further shows an advancer 201 slideably mounted in the food holder 101 to move longitudinally along the food holder 101, and configured to engage against the sliceable item of food 107. Also depicted is a ratchet advance mechanism 202a-e, coupled to the lid 109 and to the advancer 201, and configured to incrementally move the advancer 201, and consequently the sliceable item of food 107, towards the dispensing opening 108 each time the lid 109 is moved to the open position from the closed position. In this embodiment, the ratchet advance mechanism 202a-e comprises a moveable toothed rack 202a coupled to the lid 109, longitudinally disposed in the food holder 101, and a first pawl 202b disposed on the advancer 201, the moveable toothed rack 202a positioned to engage against the first pawl 202b. The lid 109 is configured to advance the moveable toothed rack 202a and the advancer 201 toward the dispensing opening 108 when the lid 109 is moved to the open position from the closed position, and to retract the moveable toothed rack 202a from the dispensing opening 108 when the lid 109 is moved to the closed position. The embodiment further comprises a stationary toothed rack 203, longitudinally disposed in the food holder 101, and a second pawl 204 disposed on the advancer 201, the stationary toothed rack 203 configured to restrain the advancer 201 from motion when the lid 109 is moved to the closed position and to permit motion of the advancer 201 with the moveable toothed rack 202a when the lid 109 is moved to the open position. The stationary toothed rack 203 may have a plurality of teeth 205. In this embodiment there further is a rotary joint (not shown) for coupling the lid 109 to the food holder 101 and a lid peg 202d and rack slot 202e for coupling the lid 109 to the moveable toothed rack 202a in the ratchet advance mechanism 202a-e. In this particular embodiment, the ratchet advance mechanism 202a-e includes two moveable toothed racks 202a located along each sidewall, two stationary toothed racks 203 located along the top and bottom walls, and two first pawls 202b and two second pawls 204 located on the advancer 201. The redundancy of many of the components in this embodiment provides a means for creating equal and opposing off axis forces to enable smoother motion; however, in alternative embodiments one of each component may be used or more than two of each component may be used.
(26) FIG. 3 is a cross sectional side view of the embodiment of FIG. 1 with the lid 109 in a first open position 301. When the lid 109 is moved to the first open position 301, the lid pegs 202d located on the lid 109 come in contact with the rack slots 202e located on the moveable toothed rack 202a of the ratchet advance mechanism 202a-e. The width of the rack slots 202e is sufficiently wide so as to delay the transfer of motion from the lid pegs 202d on the lid 109 to the rack slots 202e on the moveable toothed rack 202a until the end cap 110 is sufficiently lifted past the position where it covers the dispensing opening 108. In this way, when the sliceable item of food 107 is advanced by the advancer 201, it can move freely through the dispensing opening 108.
(27) FIG. 4 is a cross sectional side view of the embodiment of FIG. 1 with the lid 109 in a second open position 401. In this position the lid pegs 202d engage with a rack slot 202e on the moveable toothed rack 202a, and a tooth on the moveable toothed rack 202a engages with the first pawl 202b on the advancer 201, together the ratchet engagement mechanism. This action advances the advancer 201 which then advances a predetermined portion of the sliceable item of food 107 forward past the dispensing opening 108. For example, the second open position 401 may advance the advancer 201 the length of two teeth of the stationary toothed rack 203, each having a teeth spacing of 0.10 inches, for a total of 0.20 inches. The sliceable item of food 107 may be a 1.25″ square cross section block, so that the portion of the sliceable item of food 107 advanced through the dispensing opening 108 may represent one teaspoon. This amount will be dispensed if the lid 109 is now closed. The portion of the sliceable item of food 107 advanced past the dispensing opening 108 is directly relatable to the amount the lid 109 is opened as the motion transferred through the ratchet engagement mechanism is directly relatable to the number of teeth of the stationary toothed rack 203 passed by the first pawl 202b on the advancer 201.
(28) FIG. 5 is a cross sectional side view of a first embodiment with the lid 109 in a third open position 501. In this position the additional motion of the lid 109 pushes on the lid pegs 202d further towards the dispensing opening 108 which pushes further on the rack slot 202e of the moveable toothed rack 202a which then transfers additional motion of the moveable toothed rack 202a through the first pawl 202b to the advancer 201. The advancer 201 then moves a greater predetermined portion of the sliceable item of food 107 forward past the dispensing opening 108. For example, in this embodiment the third open position 501 may advance the advancer 201 a total distance of six teeth 205 of the stationary toothed rack from the closed position, each tooth being spaced 0.10 inches apart. The sliceable item of food 107 may have a 1.25″ square cross section block so that the portion of the sliceable item of food 107 advanced through the dispensing opening 108 may represents one tablespoon. This amount will be dispensed if the lid 109 is now closed.
(29) FIG. 6A and FIG. 6B show isometric views of the advancer 201 of the embodiment of FIG. 1 showing two opposing first pawls 202b and two opposing second pawls 204. While the embodiment may also have one or a greater number of pawls, two are exemplarily used to equalize the resultant off axis forces as the advancer 201 moves along the longitudinal axis of the food holder 101. Each first pawl 202b has a leading edge 601 and a trailing edge 602. Each second pawl 204 has a leading edge 603 and a trailing edge 604. The leading edges 601 and 603 have a slant to slideably disengage with the edge of a tooth 205 of the stationary toothed rack 203 and a tooth 202c of the moveable toothed rack 202a, allowing the advancer 201 to move freely past the teeth of the stationary and moveable toothed racks in the forward direction. The trailing edges 602 and 604 have an orthogonal component that engages with the tooth 205 of the stationary toothed rack 203 and the tooth 202c of the moveable toothed rack 202a, enabling the transfer of motion.
(30) FIG. 7 is a side view of the advancer 201 of FIG. 6 showing the flexure of the two second pawls 204 that occurs as they move past the two stationary toothed racks 203 upon the forward movement of the advancer 201.
(31) FIG. 8 is a cross sectional side view of the embodiment of FIG. 1 showing the lid 109 moving from an open position to a partially closed position. As the lid 109 is moved towards the partially closed position, the motion of the lid 109 moves the lid pegs 202d back to the position where they engage the rack slots 202e on the moveable toothed racks 202a so that the moveable toothed racks 202s pull back to their original position as the lid 109 is fully closed. Engagement of the second pawls 204 located on the advancer 201 with a tooth 205 (as depicted in FIG. 2) located on each of the stationary toothed racks 203 affixed to the walls of the food holder 101 prevent rearward motion of the advancer 201 as the moveable toothed racks 202a are pulled rearward.
(32) FIG. 9 is a cross sectional side view of the embodiment of FIG. 1 showing the lower edge 112 of the end cap 110 contacting the advanced portion of the sliceable item of food 107 as the lid 109 moves towards the closed position. This figure shows how further moving the lid 109 towards the closed position engages the lid pegs 202d with the rack slots 202e located on the moveable toothed racks 202a. The lower edge 112 of the end cap 110 is brought in contact with the sliceable item of food 107 and begins to separate the portion that was advanced out the dispensing opening 108 from the sliceable item of food 107 that remains in the food holder 101.
(33) FIG. 10A and FIG. 10B are isometric views of the embodiment of FIG. 1 with the lid 109 in a closed position after slicing and dispensing a tablespoon (FIG. 10A) and teaspoon (FIG. 10B) portion of dispensed food 1001. The lower edge 112 of the end cap 110 slices through the sliceable item of food 107. Because there is a significant moment arm around the pivot point of the lid 109, even foods that are hard such as cucumbers and celery can easily be sliced by a dull and relatively weak material like three-dimensionally printed polylactide plastic. Upon returning to the closed position, the embodiment is now in position to operate again to dispense the next portion of the stored sliceable item of food 107. After the sliceable item of food 107 is fully dispensed, the advancer 201 is advanced through the dispensing opening 108 by opening and closing the lid 109 until the advancer 201 is moved sufficiently forward to be completely removed from the food holder 101. A new sliceable item of food 107 can now be placed in the food holder 101 and the advancer 201 placed in an opening in the first end 106 and pushed forward sufficiently to engage upon the sliceable item of food 107. Once this is done the embodiment is ready to operate once again in the same manner as described above.
(34) FIG. 11 is a perspective view of alternative component configurations of the embodiment of FIG. 1 with the stationary toothed racks 203 and moveable toothed racks 202a bowed toward the sliceable item of food 107 so as to create a compressive force orthogonal to the longitudinal axis on the sliceable item of food 107. This reduces a risk that the sliceable item of food 107 would fall out of the food holder 101. While this shows one potential embodiment, other embodiments include bowing a portion of the static toothed rack 203 or bowing the moveable toothed rack 202a or any combination of these configurations. The flexibility of the material along with the selected geometry allows a specific holding force to be defined.
(35) In addition, the air gaps 1101 created by bowing the moveable toothed racks 202a and the stationary toothed racks 203 serve to provide additional insulation for the sliceable item of food 107. The air gaps 1101 serve to provide insulation for allowing the temperature of the sliceable item of food 107 to stay at a consistent temperature upon removal from cold or hot storage.
(36) FIG. 12 is a perspective view of a second embodiment of the present invention with the lid 109 in an open position where the lid 109 moves in a largely horizontal motion. In this embodiment an upward motion is used to lift the lid 109 and open the food holder 101 to act upon the ratchet advance mechanism 202a-e. This moves the sliceable item of food 107 forward toward the first end 105 of the food holder 101. Then, a downward motion is used to close the lid 109 and engage the lower edge 112 of the end cap 110 with the sliceable item of food 107 to cut and dispense it from the food holder 101.
(37) FIG. 13 is a cut away perspective view of the embodiment shown in FIG. 12 with the lid 109 in the closed position. In this embodiment, the ratchet advance mechanism 202a-e includes a rack peg 1301 located on the moveable toothed rack 202a and a lid channel 1302 located on the inner surface of the lid 109 as well as the first pawl 202b located on the advancer 201. Lifting the lid 109 higher creates additional motion that then advances a greater portion of the sliceable item of food 107 through the dispensing opening 108.
(38) FIG. 14 is a perspective view of a third embodiment of the present invention with the lid 109 in an open position that uses an alternative configuration of the ratchet advance mechanism 202a-e and an alternative location of the second pawl 204. In this configuration the moveable toothed rack 202a and two stationary toothed racks 203 are mounted along the sidewall 104 of the food holder 101. However, it is expressly contemplated that any number of moveable toothed racks 202a and stationary toothed racks 203 may be mounted along the sidewalls 104 of the food holder 101.
(39) FIG. 15 is a cut away perspective view of the embodiment shown in FIG. 14 as the lid 109 moves towards the closed position. In this embodiment, the second pawl 204 is mounted on the same side of the advancer 201 as the first pawl 202b. The stationary toothed rack 203 and the moveable toothed rack 202a are both mounted along the sidewall 104 of the food holder 101. The ratchet advance mechanism 202a-e includes a link 1501 with a first rotary joint 1502 and a second rotary joint 1503 where the first rotary joint 1502 is coupled to the lid 109 and the link 1501 and the second rotary joint 1503 is coupled to the link 1501 and the moveable toothed rack 202a. The second rotary joint 1503 contains a slot to allow motion of the lid 109 prior to the movement of the link 1501 causing movement of the moveable toothed rack 202a so that the lid 109 can move past the dispensing opening 108 before the sliceable item of food 107 is advanced through the dispensing opening 108.
(40) FIG. 16A and FIG. 16B are close up isometric views of the embodiment of FIG. 1 showing the increment adjuster 1601 placed in distinct positions 1602A-E on the food holder 101 to interrupt the path of motion of the lid 109. In FIG. 16A the embodiment shows five distinct position options 1602A-E with the increment adjuster 1601 set to the third position and in FIG. 16B the increment adjuster 1601 is moved to the fifth position 1602E. Each distinct position 1602 results in the increment adjuster 1601 acting on the lid sidewall 1603 in a distinct location, allowing the lid 109 to open a distinct amount and resulting in a different thickness of the sliceable item of food 107 dispensed. In this embodiment the position of the increment adjuster 1601 is achieved by sliding the increment adjuster 1601 along a longitudinal axis on the sidewall 104 of the food holder 101. While this is an example of one embodiment, the increment adjuster 1601 can be located to engage with and resist motion of any member in the motion path of the lid 109 including but not limited to the lid 109, the food holder 101, and the moveable toothed rack 202a
(41) FIG. 17A and FIG. 17B are close up isometric views of the embodiment of FIG. 4 showing the increment adjuster 1601 placed in distinct positions 1602 on the food holder 101 to interrupt the path of motion of the lid 109. FIG. 17A shows four distinct position options 1602 with the increment adjuster 1601 set to the first position 1602A. In FIG. 16B the increment adjuster 1601 is moved to the second position 1602B. Each distinct position 1602 results in the increment adjuster 1601 acting on the lid sidewall 1603 in a distinct location, allowing the lid 109 to open a distinct amount and resulting in a different thickness of the sliceable item of food 107 dispensed. In this embodiment the position of the increment adjuster 1601 is achieved by rotating the increment adjuster 1601 around a rotation axis 1701 located on the increment adjuster 1601 mounted to the food holder 101.
