    Abstract

    An herb and spice grinder has a plurality of sections that are removably connected together. A hole is formed at the outer periphery of each of the plurality of sections. The plurality of sections can be rotated relative to one another so that the holes align to form a passageway. The bolt of a lock can be inserted through the passageway so as to prevent the sections from rotating relative to one another and to prevent the sections from being separated from one another. As a result, undesired access to the contents of such herb and spice grinder is effectively prevented. Preferably, rotation of a top section relative to an intermediate section causes a grinding of the herb or spice. The ground material passes through openings in the intermediate section to be stored in a receptacle formed in a bottom section. A blade for a grinder is also disclosed.

    DETAILED DESCRIPTION OF THE INVENTION

    [0051] Referring to FIG. 1, there is shown the herb and spice grinder 10 in accordance with the teachings of the present invention. The herb and spice grinder 10 includes a first section 12, a second section 14, and a third section 16 that are removably connected together. Each of the sections will have an outer periphery. A hole is formed at the outer periphery of each of the sections 12, 14 and 16. The sections 12, 14 and 16 are rotatable with respect to each other so that the holes align with each other. In FIG. 1, it can be seen that there is a hole 18 that aligns with a corresponding hole of the second section 12 and with a hole 20 of the third section 16, thus forming a passageway therethrough. When the holes 18 and 20 (along with the hole of the second section 14) are aligned, it is possible to install a lock 22. The bolt of the lock 22 can extend through the respective holes of the sections 12, 14 and 16.

    [0052] In FIG. 1, it can be seen that there is a combination lock 24 that is cooperative with the bolt of the lock 22 so that the user can set a desired combination. The lock 22 can be properly installed through the holes of the sections 12, 14 and 16 and locked so as to prevent undesired access to the contents of the herb and spice grinder 10. As such, the herb and spice grinder of the present invention can prevent possible health and safety risks to persons, such as children, by limiting access to the contents of the herb and spice grinder 10. The lock 22 can be a padlock, including combination and keyed lock, but could also be any other type of lock having a bolt or cable which can be inserted through the holes.

    [0053] FIG. 2 shows the herb and spice grinder 10 without the lock 22 installed. In particular, it can be seen that each of the sections 12, 14 and 16 has a generally identical exterior surface. In particular, each of the sections 12, 14 and 16 is generally triangular shape and has rounded corners 26, 28 and 30. An indentation is formed in each of these rounded corners so as to facilitate the ability to grip the respective sections 12, 14 and 16 of the herb and spice grinder 10. It can be seen that there are holes 18, 32 and 34 formed adjacent to each of the rounded corners 28, 26 and 30, respectively. As such, as stated before, when the respective holes of each of the sections 12, 14 and 16 are aligned, it is possible to put the bolt of a lock therethrough so as to secure each of these sections 12, 14 and 16 together and to prevent access to the contents.

    [0054] FIG. 3 is an exploded view from an upper perspective of the herb and spice grinder 10. Initially, there is a first section 12 which is a cap section. The second section 14 has a top surface 40 that will face the underside 42 of the first section 12. An O-ring 44 will fit around a shoulder 46 of the second section 14. Shoulder 46 extends upwardly for a short distance from the top surface 40. A plurality of blades 48 are positioned within a central collection pocket 50 of the second section 14. The central collection pocket 50 has a desired depth. The plurality of blades 48 will extend upwardly in spaced relation to each other within the central collection pocket 50. As will be described hereinafter, the bottom of the central collection pocket 50 has a plurality of openings or holes therethrough so as to allow the ground and shredded herbs and spices to be passed downwardly toward the third section 16.

    [0055] The third section 16 is illustrated as having a receptacle 52 formed centrally thereof. Receptacle 52 has a male external thread 54 formed therearound. The male external thread 54 will engage with the female internal thread on the underside 56 of the second section 14. When the second section 14 is fully rotated so as to fully engage with the threads 54 of the third section 16, the respective holes at the corners of the second section 14 will align with the holes 56 and 58 of the third section 16.

    [0056] FIG. 4 shows of a perspective exploded bottom view of the herb and spice grinder of the present invention. As can be seen, the underside 42 of the first section 12 also includes a pocket 60 formed centrally thereof. Another plurality of blades 62 are affixed within the pocket 60 so as to extend outwardly therefrom. The plurality of blades 62 will engage with the plurality of blades 48 of the second section 14. When the first section 12 is rotated with respect to the second section 14, the close relationship between the blades 48 and 62 will create the necessary grinding effect and shredding effect so as to reduce the herbs and spices that may be deposited within the central collection pocket 48 of the second section 14 to a size suitable for passing through the holes 64 of the second section 14.

    [0057] In FIG. 4, there is a cutter 66 affixed to a post extending downwardly within the pocket 60 of the first section 12. Cutter 66 will serve to shred material that is positioned within the central collection pocket 48 of the second section 14. The blades 48 of the second section 14 will extend in close proximity to the cutter 66 when the first section 12 is positioned onto the second section 14. As a result of this configuration, the rotation of the first section 12 with respect to the second section 14 will create a shredding effect through the use of the cutter 66 and will create a grinding effect through the close interaction of the blades 48 of the second section 14 and the blades 62 of the first section 12.

    [0058] FIG. 4 shows that the second section 14 has female threads 68 formed at a bottom thereof. Female threads 68 will engage with the male threads 54 of the third section 16 so that the second section 14 is threadedly secured to the third section 16.

    [0059] FIG. 5 is a bottom view of the first section 12. It can be seen that the first section 12 has holes 18, 32 and 34 formed at the various corners thereof. In particular, hole 18 is adjacent to the corner 28. Hole 34 is adjacent to the corner 26. Hole 34 is adjacent to the corner 30. Each of the corners 26, 28 and 30 is indented inwardly and curved. Furthermore, hole 34 has an oval shape in comparison with the round configuration of the holes 18 and 32.

    [0060] FIG. 5 shows the cutter 66 as located centrally of the pocket 60. The blades 62 are arranged in a first circular array 72 and a second circular array 74. The first circular array 72 has a greater radius than the second circular array 74. Each of the blades 62 will have a configuration similar to that shown in FIG. 6. The cutter 66 is located within an interior of the second circular array 74.

    [0061] FIG. 6 is a top view of the second section 14. The second section 14 includes holes 80, 82 and 84. In general, the outer periphery of the second section 14 will be identical to the outer periphery of the first section 12. In FIG. 6, it can be seen that the blades 48 are arranged in a first circular array 86 and a second circular array 88. The first circular array 86 has a greater radius than the second circular array 88. There are plurality of holes 90 that extend through the second section 14. Some of the holes are located toward the outer periphery of the central collection pocket 50. Some of the other holes are formed in a circular pattern between the first circular array of blades 86 and the second circular array of blades 88. Other holes are positioned inwardly of the second circular array of blades 88 generally adjacent to the central area that serves to receive the cutter 66. The various holes allow the ground and shredded material to be deposited, by gravity, into the third section 16.

    [0062] FIG. 7 shows the improved configuration of a blade 100 as used in each of the first section 12 in the second section 14 of the present invention. FIG. 7 shows a cross-sectional view of this blade 100. The blade 100 includes a first curved end surface 102, a pair of curved side surfaces 104 and 106, a pair of curved end surfaces 108 and 110 and a central curved end surface 112. The first curved end surface 102 is curved inwardly. Each of the pair of curved side surfaces 104 and 106 are also curved inwardly and extend from respective ends of the first curved end surface 102. The pair of curved end surfaces 108 and 110 also are curved inwardly. The pair of curved end surfaces 108 and 110 are opposite to the first curved end surface. Each of the curved end surface 108 extends inwardly from an end of the curved side surface 104 opposite the first curved end surface 102. Similarly, the second curved end surface 110 extends inwardly from an end of the curved side surface 106 opposite the end of the first curved end surface 102. The central curved end surface 112 is also curved inwardly and is located opposite to the first curved end surface 102 and is located between the pair of second curved end surfaces 108 and 110.

    [0063] It should be noted that a width between outer edges of the pair of second curved end surfaces 108 and 110 is greater than a width of the first curved end surface 102. A radius of the central curved end surface 112 is greater than a radius of the first curved end surface 102 and greater than a radius of each of the pair of second curved end surfaces 108 and 110.

    [0064] After experimentation, it was found that this configuration of cutter blades improves the cutting and grinding action of the herb and spice grinder 10 of the present invention. Each of the curved surfaces acts to create a greater pinching effect when interacting with adjacent blades so as to achieve a greater cutting and grinding effect.

    [0065] The cutter 66 is illustrated in FIG. 8. The cutter 66 is mounted to a post 120 which extends downwardly from the bottom of the first section 12 and located centrally of the pocket 60. The cutter 66 has a pinwheel shape. The cutter 66 has a first pointed end 122, a second pointed end 124 and a third pointed end 126. There is a first S-shaped edge 128 that extends between the pointed ends 122 and 126. Another S-shape edge 130 extends between pointed end 124 and pointed end 126. A third S-shape edge 132 extends between the pointed end 122 and the pointed end 124. This curvature facilitates the ability to shred the herbs and spices there would be placed into the herb and spice grinder of the present invention.

    [0066] The foregoing disclosure and description of the present invention is illustrative and explanatory thereof. Various changes in the details of the illustrated construction can be made within the scope of the appended claims without departing from the true spirit of the invention. The present invention should only be limited by the following claims and their legal equivalents.
