I. Exemplary Grinder
FIGS. 1-3 illustrate an exemplary grinder (100). It will be appreciated that grinder (100) may be used generally to grind spices and minerals for use in cooking or the preparation of food dishes. In some versions, grinder (100) may be used to grind, for example, salt or pepper. It will be understood that even though the description below refers to grinder (100) and other versions of grinder being used with “minerals,” any suitable material may be ground using grinder (100) as would be apparent to one of ordinary skill in the art in view of the teachings herein. For instance, spices, minerals, herbs, coffees, seeds, or any other suitable material may be ground using grinder (100). Once ground, the ground ingredient leaves grinder (100) to be used in any suitable manner by the user. It will be appreciated that other exemplary ways of using grinder (100) may be used as would be apparent to one ordinary skill in the art in view of the teachings herein. Further details regarding the detailed mechanism for grinding food will be discussed further below.
In an exemplary version shown in FIG. 1, grinder (100) comprises a head (102) and a bottle (104). Bottle (104) has a generally cylindrical shape with a flared bottom. A cap (106) is placed upon head (102) and accordingly may also be removed from head (102) when grinder (100) is ready for use. Cap (106) is operable to keep dirt, dust, debris, and other foreign objects out of head (102) when grinder (100) is not being used. FIG. 2, for example, shows grinder (100) with cap (106) removed. Head (102) is operable generally to grind spices or minerals contained within bottle (104). Details regarding the grinding mechanism will be discussed further below. In the exemplary version, head (102) attaches to bottle (104) via a snap fit, but in other versions, it will be appreciated that head (102) may be attached to bottle (104), through, for example, a screw-fit or friction-fit connection, or any other suitable connection as would be apparent to one of ordinary skill in the art in view of the teachings herein. It will be understood though that once head (102) is attached to bottle (104), head (102) may still be rotated in relation to bottle (104). Head (102) includes a head recess (108) that seats a radial slider ring (110). Radial slider ring (110) may be adjusted by the user to change the coarseness of the grind caused by head (102), which will be discussed in further detail below. Thereafter, generally speaking, grinder (100) may be flipped upside down, head (102) may be rotated in relation to bottle (104), spices within bottle (104) may be ground, and ground spices and/or minerals may leave head (102).
FIG. 3 shows a cross sectional view of grinder (100). As was previously described, cap (106) is operable to snap onto head (102) of grinder (100). In the illustrated version, cap (106) may be attached to head (102) via friction and/or a complementary notched portion (112) operable to secure cap (106) to head (102). Cap (106) in some versions may have a tab that must be removed prior to removing cap (106) from grinder (100) to ensure that grinder (100) has not been tampered with prior to use. Other suitable variations may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein. It will be appreciated that cap (106) is operable to prevent dust or other foreign particles from getting into head (102) or other parts of grinder (100). It will be appreciated that other suitable mechanisms for attaching cap (106) to head (102) may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein. It will further be appreciated that in some versions, cap (106) may be omitted entirely. In addition or in the alternative, a sticker (118) made of foil or any other suitable material may also be used to prevent dust from entering grinder (100) prior to use.
Head (102) comprises a body portion (122) operable to house various portions of grinder (100) as will be discussed in further detail below. Body portion (122) of the exemplary version has a cylindrical shape operable to be grasped by the user during use. While body portion (122) of the illustrated version has a generally smooth, cylindrical shape, body portion (122) may have any suitable shape as would be apparent to one of ordinary skill in the art in view of the teachings herein. For instance, body portion (122) may include a rubberized grip for holding that encircles body portion (122) or at least a part of body portion (122). Furthermore, body portion (122) may also have any other suitable shape including square shapes, elliptical, etc.
Radial slider ring (110) is seated within body portion (122). Body portion (122) of head (102) is attached to bottle (104) through grinder base (124). Body portion (122) is clipped to grinder base (124) such that body portion (122) can rotate in relation to grinder base (124) without detaching from grinder base (124). While seated in body portion (122), radial slider ring (110) is operable to rotate through a plurality of positions. For instance, radial slider ring (110) of the illustrated version may rotate through 4 discrete positions representing different coarseness settings, though any suitable number of positions may be used including more or less positions than 4. Such movement of radial slider ring (110) will be discussed in further detail below with respect to how radial slider ring (110) controls the coarseness of the grind of a mineral or other material to be ground.
Head (102) comprises an inner grinder element (116) and an outer grinder element (114). Inner grinder element (116) is operable generally to rotate in relation to outer grinder element (114) to grind spices and/or minerals therebetween. Outer grinder element (114) is operable to move up or down longitudinally in relation to inner grinder element (116). Inner grinder element (116) and outer grinder element (114) define a grinding space therebetween whereby increasing that space increases the coarseness of the grind and decreasing that space increases the fineness of the grind.
Outer grinder element (114) and inner grinder element (116) are positioned concentrically in relation to one another in the exemplary version. A shaft (130) extends through the center of both the outer grinder element (114) and inner grinder element (116). Shaft (130) has a shape that complements the contour of inner grinder element (116) such that inner grinder element (116) fits snuggly against shaft (130). In the illustrated version, shaft (130) has graduated sides operable to match with the shape of inner grinder element (116) and to prevent shaft (130) from falling through inner grinder element (116), but it will be appreciated that in some versions, shaft (130) may have a cylindrical shape or any suitable shape as would be apparent to one of ordinary skill in the art in view of the teachings herein. Shaft (130) is operable to hold outer grinder element (114) and inner grinder element (116) together while still allowing outer grinder element (114) to move relative to inner grinder element (116). As a result, inner grinder element (116) is able to rotate in relation to outer grinder element (114) to grind a mineral therebetween.
Inner grinder element (116) sits upon a neck sleeve (134), which is shown in the illustrated version as a cylindrical sleeve. It will be understood that neck sleeve (134) may include other suitable shapes as would be apparent to one of ordinary skill in the art in view of the teachings herein. Shaft (130) extends through neck sleeve (134), and as a result, neck sleeve (134) acts as a spacer between inner grinder element (116) and grinder base (124). A bottom portion (136) of shaft (130) is positioned through a neck sleeve (134) and leads to a blunt hook (132). Blunt hook (132) keeps shaft (130) coupled to neck sleeve (134).
Hook (132) is constructed such that shaft (130) cannot be pulled back through neck sleeve (134). In the exemplary version, hook (132) is simply sized to be wider than neck sleeve (134) but any suitable mechanism for preventing hook (132) from sliding back through neck sleeve (134) may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein. In some versions it will be appreciated that hook (132) have other shapes and configurations such as, for example, a split mushroom top shape, etc., or any other suitable shape as would be apparent to one of ordinary skill in the art in view of the teachings herein. It will be appreciated that hook (132) may deform to fit through neck sleeve (134) wherein after hook (132) expands to prevent hook (132) from being pulled back through neck sleeve (134).
Outer grinder element (114) includes an internal annular flange (128) at the bottom of outer grinder element (114). Internal annular flange (128) is coupled with internal body clips (120), which are in contact with radial slider ring (110) within body portion (122). Furthermore, radial slider ring (110) is screwingly coupled with body portion (122) due to radial slider ring (110) riding along angled ramps, such as those shown and discussed below in FIG. 4. As radial slider ring (110) rotates in one direction, for instance, clockwise, then radial slider ring (110) rises axially within body portion (122). As radial slider ring (110) rotates in the opposite direction, radial slider ring (110) descends axially within body portion (122). Since radial slider ring (110) is coupled to annular flange (128) of outer grinder element (114) through internal body clips (120), as radial slider ring (110) rises and descends axially in relation to body portion (122), outer grinder element (114) rises and descends axially as well.
Shaft (130) and inner grinder element (116) remain axially stationary as outer grinder element (114) rises and descends. As a result, as a user turns radial slider ring (110) to raise or lower outer grinder element (114) in relation to body portion (122), outer grinder element (114) accordingly moves axially away from or toward inner grinder element (116). Thus, the user may rotate radial slider ring (110) to control the size of the space between inner grinder element (116) and outer grinder element (114).
For example, if the user desires a coarser grind, then the user rotates radial slider ring (110) in one direction. As a result, radial slider ring (110) screwingly descends in relation to body portion (122), which pushes annular flange (128) and outer grinder element (114) axially downward in relation to inner grinder element (116). The space between inner grinder element (116) and outer grinder element (114) therefore increases. Thereafter, the user can turn bottle (104) over and rotate bottle (104), which causes inner grinder element (116) to rotate in relation to outer grinder element (114), thereby grinding and/or crushing mineral therebetween.
In contrast, if the user desires a finer grind, then the user rotates radial slider in the opposite direction. Radial slider ring (110) then screwingly ascends in relation to body portion (122), which pushes annular flange (128) and outer grinder element (114) axially upwards in relation to inner grinder element (116). The space between inner grinder element (116) and outer grinder element (114) decreases. Thereafter, the user can turn bottle (104) over and rotate bottle (104), which causes inner grinder element (116) to rotate in relation to outer grinder element (114), thereby grinding and/or crushing mineral therebetween, resulting in a finer grind.
II. Alternative Exemplary Grinder
FIG. 4 shows an alternative exemplary version of a grinder (200) having a slightly alternatively designed head (202) positioned upon a bottle (204). Head (202) covers recess (224) of bottle (204) while still being able to rotate around recess (224) when attached to bottle (204). It will be appreciated that grinder (200) of FIG. 4 operates in a substantially similar manner as grinder (100) of FIG. 1. Head (202) includes a body portion (222) and a radial slider ring (210) seated within body portion (222). Radial slider ring (210) has a tab (211) for rotation using a user's finger or thumb to rotate radial slider ring (210) within head (202). Radial slider ring (210) may be used to control the coarseness of the grind of grinder (200).
Radial slider ring (210) in the exemplary version is screwingly coupled to head (202) via clips (221) in contact with angled ramps (220), which encircle the inner portion of head (202). As a result, when radial slider ring (210) is rotated, it ascends or descends based on the direction it is rotated along angled ramp (220). A ring base (238) sits at the bottom of radial slider (210) such that ring base (238) can support neck sleeve (234). A shaft (230) ending in a hook (232) extends through inner grinder element (216) and neck sleeve (234) to hold inner grinder element (216) and neck sleeve (234) together.
As previously mentioned, the coarseness of the grind may be controlled by changing the distance between outer grinder element (214) and inner grinder element (216) where a larger distance between outer grinder element (214) and inner grinder element (216) results in a coarser grind and where a smaller space results in a more fine grind. FIGS. 5A-7B show grinder (200) as it moves through three merely exemplary coarseness settings. While the exemplary version shows three coarseness settings, it will be appreciated that other suitable coarseness settings may be used as well.
In FIGS. 5A-5B, radial slider ring (210) is in a coarse setting position. As can be seen in FIG. 5A, radial slider ring (210) is positioned relatively low within head (202), which corresponds to a coarse setting. Radial slider ring (210) in communication with body portion (222) via angled ramp (220). Radial slider ring (210) and clips (221) hold onto angled ramp (220). Angled ramp (220) extends around head (202) such that as radial slider ring (210) rotates, radial slider ring (210) rides along angled ramp (220) as angled ramp (220) ascends. As radial slider ring (210) rotates in the other direction, radial slider ring (210) rides along angled ramp (220) as angled ramp (220) descends. Furthermore, outer grinder element (214) is coupled to radial slider ring (210). As radial slider ring (210) is rotated, radial slider ring (210) raises and lowers, and outer grinder element (214) raises and lowers while inner grinder element (216) remains axially stationary. For example, in FIGS. 5A-5B, which show a relatively coarse setting, the space between outer grinder element (214) and inner grinder element (216) is approximately 0.95 mm. However, it will be appreciated that such space between inner grinder element (216) and outer grinder element (214) may be any suitable size as will be apparent to one of ordinary skill in the art in view of the teachings herein.
FIGS. 6A-6B depict a medium setting wherein the space between inner grinder element (216) and outer grinder element (214) may have a space of approximately 0.6 mm. As seen in FIG. 6A, radial slider ring (210) is positioned slightly higher within head (202) in comparison to radial slider ring (210)'s position in FIG. 5A, which represents a medium grind setting. By rotating radial slider ring (210), radial slider ring (210) travels along angled ramp (220) such that outer grinder element (214) rises, thereby narrowing the space between outer grinder element (214) and inner grinder element (216) to be in the medium coarseness setting.
FIGS. 7A-7B depict a relatively fine setting wherein the space between inner grinder element (216) and outer grinder element (214) may have a space of approximately 0.34 mm. As seen in FIG. 7A, radial slider ring (210) is positioned higher within head (202) in comparison to radial slider ring (210)'s position in FIG. 6A, which represents a fine grind setting. By rotating radial slider ring (210) even more, radial slider ring (210) continues to ascend along angled ramp (220) such that outer grinder element (214) rises further, thereby narrowing the space between outer grinder element (214) and inner grinder element (216) to be in the fine setting.
It will be understood that as radial slider ring (210) is rotated, the space between inner grinder element (216) and outer grinder element (214) gradually changes such that the user may be able to select a coarseness setting in between those shown in FIGS. 5A-7B. In other merely exemplary versions, it will be contemplated that radial slider ring (210) may be set to have discrete settings wherein the user selects between a discrete number of settings to set the coarseness of grinder (200). In some versions, an audible click may signify that a new coarseness setting has been reached. Furthermore, it will be understood that the values depicted representing the space between inner grinder element (216) and outer grinder element (214) are merely exemplary and any suitable spacing between inner grinder element (216) and outer grinder element (214) may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein. Furthermore, any distances indicated between recess (224) and angled ramp (220) are also merely exemplary. It will be understood that one of ordinary skill in the art may use different distances between recess (224) and angled ramp (220) as would be apparent to one of ordinary skill in the art in view of the teachings herein.

As can been seen more clearly in FIG. 8, radial slider (310) comprises two opposing clips (311) operable to couple radial slider (310) with neck sleeve (334) shown in FIG. 9. Radial slider (310) also includes clips (313) to couple with angled ramps (319) such that as radial slider (310) rotates, radial slider (310) rises and descends within body portion (322). Angled ramps (319) further include notches (317) able to correspond to various coarseness settings for grinder (300).
FIG. 12 shows other exemplary components of grinder (300) including hook (332), outer grinder element (314) and neck sleeve (334). Hook (332) in the exemplary version comprises a base (333) and twin hooking members (335). Hooking members (335) are constructed such that members (335) sit off-center from being coaxially aligned. Furthermore, hooking members (335) are separated as they extend from base (333). While the exemplary version shows two hooking members (335), it will be appreciated that more than two hooking members (335) may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein.
Neck sleeve (334) comprises a square shaped neck (337) operable to fit hook (332). It will be appreciated that neck (337) may be constructed to be any suitable depth as would be apparent to one of ordinary skill in the art in view of the teachings herein. It will be understood that providing neck (337) having additional depth may act to further stabilize hook (332) within neck sleeve (334).
IV. Exemplary Grinder with Seal
It will be appreciated that in some instances, as grinder (300) is being used, finer pieces of ground mineral may result in leaking of ground mineral from grinder (300). Thus, it may be desirable to construct grinder (300) such that grinder (300) is more resilient against leaking from ground material. It will be appreciated that outer grinder element (414) and body portion (422) described below may be used with any of the grinders shown such as grinder (200) shown in FIG. 4 or grinder (300) shown in FIG. 8 to assist in preventing leakage from grinder (200, 300).
FIGS. 13-14 show an alternative exemplary outer grinder element (414) for use to prevent leaking. Outer grinder element (414) comprises opposing clips (415) gripping a lip (421) that extends around the circumference of outer grinder element (414). Under lip (421) is an inner wall (417), and extending down from lip (421) is a mating portion (419). It will be appreciated that lip (421), mating portion (419) and inner wall (417) may be used to help prevent leakage of ground material. Lip (421), mating portion (419) and inner wall (417) are operable to form a seal with a sealing member, which will be discussed in further detail below.
FIG. 15 shows a perspective view of another exemplary version of a body portion (422) where FIG. 16 shows body portion (422) of FIG. 15 in a cross sectional view. It will be understood that body portion (422) is substantially similar to body portion as shown for instance in FIG. 9. Body portion (422) has a generally circular shape at one end and a rounded square shape at the other. It will be appreciated that other suitable shapes for body portion (422) may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein. In the exemplary version, body portion (422) comprises a pair of recesses (429). In the illustrated version, two recesses (429) are shown that oppose each other, but it will be appreciated that any suitable number of recesses may be used as would be apparent to one of ordinary skill. Furthermore, recesses (429) may be positioned in any suitable fashion within body portion (422). It will be understood that recesses (429) may be used to complement mating portion (419) of outer grinder element (414) shown in FIGS. 13-14, such that as the grinder is being used, recesses (429) provide a better seal with mating portion (419), thereby preventing any leakage of ground material that might otherwise occur. Furthermore, the illustrated version comprises a seal (427) encircling an inner portion of body portion (422). Seal (427) may comprise a rubber, silicon, plastic, or any other suitable material operable to form a seal as will be apparent to one of ordinary skill in the art in view of the teachings herein. It will be understood that seal (427), alone or in conjunction with recesses (429) may provide further sealing with mating portion (419) by complementing inner wall (417) and lip (421) of outer grinder element (414). Seal (427) is also operable to follow the contour of recesses (429), thereby enabling a more secure seal (427). As a result, as a user grinds material with outer grinder element (414), ground material may be less likely to leak due to the seal between inner wall (417) and seal (427).
