a blade mounted on a blade holder, said blade holder having an interior surface defined by a collar;
at least one slot on said interior surface;
said collar having a latch with at least one notch for engaging said locking rib;
wherein said blade assembly attaches to said open-end of said container by inserting said tongue protrusion into said slot and rotating said blade assembly such that said rim of said container is enclosed by the blade assembly;
wherein when said notch is not engaged with said rib, said blade assembly can rotate relative to said container;
wherein when said notch is engaged with said rib, said blade assembly cannot rotate relative to said container.
2. The blender according to claim 1 , wherein:
said locking rib is located relative to said tongue protrusion on said container such that said notch on said latch can only be engaged with said locking rib when said tongue protrusion is at least partially inserted into said slot on said blade assembly.
3. The blender according to claim 2 , said latch further comprises a first notch, a second notch, and a third notch, wherein:
when said first notch is engaged with said locking rib, a first portion of said tongue protrusion is engaged with said slot;
when said second notch is engaged with said locking rib, a second portion of said tongue protrusion is engaged with said slot, said second portion being longer than said first portion;
when said third notch is engaged with said rib, a third portion of said tongue protrusion is engaged with said slot, said third portion being longer than said second portion.
4. The blender according to claim 2 , said blender further wherein:
said latch is pivotally connected to said collar such that said latch can pivot between a closed position and an open position;
said latch is mounted on a resilient element, which maintains said latch in said closed position;
wherein, when a portion of said latch is pushed to depress said resilient element, said latch pivots said notch to said open position.
5. The blender according to claim 4 , wherein:
when said latch is in said open position, said blade assembly can be rotated to position said notch over said locking rib;
when said latch is in said closed position, said notch engages said locking rib to prevent said blade assembly from being rotated.
6. The blender according to claim 5 , further comprising:
a base having a motor for operating said blender when said blade assembly is mounted on said base, said base having a protrusion;
wherein when said blade assembly is mounted on said base, said protrusion prevents said latch from being depressed to prevent said latch from pivoting said open position so that said latch cannot be unlocked while said blade assembly is mounted on said base.
7. A blender comprising:
a container, said container having:
an open-end;
a locking rib located proximate to said open-end;
a blade assembly attachable to said open-end of said container, said blade assembly comprising:
a blade mounted on a blade holder, said blade holder is defined by a collar;
said collar having a latch with at least one notch for engaging said locking rib;
wherein when said notch is not engaged with said rib, said blade assembly can rotate relative to said container;
wherein when said notch is engaged with said rib, said blade assembly cannot rotate relative to said container.
8. The blender according to claim 7 , said latch further comprises a first notch, a second notch, and a third notch, a tongue protrusion, and a slot, wherein:
the tongue protrusion is located proximate to said open-end of the container;
the slot is located proximate to said collar of said blade assembly;
when said first notch is engaged with said locking rib, a first portion of said tongue protrusion is engaged with said slot;
when said second notch is engaged with said locking rib, a second portion of said tongue protrusion is engaged with said slot, said second portion being longer than said first portion;
when said third notch is engaged with said rib, a third portion of said tongue protrusion is engaged with said slot, said third portion being longer than said second portion.
9. The blender according to claim 7 , said blender further wherein:
said latch is pivotally connected to said collar such that said latch can pivot between a closed position and an open position;
said latch is mounted on a resilient element, which maintains said latch in said closed position;
wherein, when a portion of said latch is pushed to depress said resilient element, said latch pivots said notch to said open position.
10. The blender according to claim 9 , wherein:
when said latch is in said open position, said blade assembly can be rotated in a forward direction to position said notch over said locking rib;
when said latch is in said closed position, said notch engages said locking rib to prevent said blade assembly from being rotated in said reverse direction.
11. The blender according to claim 10 , further comprising:
a base having a motor for operating said blender when said blade assembly is mounted on said base, said base having a protrusion;
wherein when said blade assembly is mounted on said base, said protrusion prevents said latch from being depressed to prevent said latch from pivoting said open position so that said latch cannot be unlocked while said blade assembly is mounted on said base.
12. A blender comprising:
a container, said container having:
an open-end defined by a rim,
at least one tongue protrusion located proximate to said open-end,
and a locking rib located proximate to said open-end;
a blade assembly attachable to said open-end of said container, said blade assembly comprising:
a blade mounted on a blade holder, said blade holder having an interior surface defined by a collar;
at least one slot on said interior surface;
a latch with at least one notch for engaging said locking rib;
wherein said blade assembly attaches to said open-end of said container by inserting said tongue protrusion into said slot and rotating said blade assembly such that said rim of said container is enclosed by the blade assembly;
wherein when said notch is not engaged with said rib, said blade assembly can rotate relative to said container;
wherein when said notch is engaged with said rib, said blade assembly cannot rotate relative to said container.
13. The blender according to claim 12 , wherein:
said locking rib is located relative to said tongue protrusion on said container such that said notch on said latch can only be engaged with said locking rib when said tongue protrusion is at least partially inserted into said slot on said blade assembly.
14. The blender according to claim 13 , said latch further comprises a first notch, a second notch, and a third notch, wherein:
when said first notch is engaged with said locking rib, a first portion of said tongue protrusion is engaged with said slot;
when said second notch is engaged with said locking rib, a second portion of said tongue protrusion is engaged with said slot, said second portion being longer than said first portion;
when said third notch is engaged with said rib, a third portion of said tongue protrusion is engaged with said slot, said third portion being longer than said second portion.
15. The blender according to claim 13 , said blender further wherein:
said latch is pivotally connected to said collar such that said latch can pivot between a closed position and an open position;
said latch is mounted on a resilient element, which maintains said latch in said closed position;
wherein, when a portion of said latch is pushed to depress said resilient element, said latch pivots said notch to said open position.
16. The blender according to claim 15 , wherein:
when said latch is in said open position, said blade assembly can be rotated to position said notch over said locking rib;
when said latch is in said closed position, said notch engages said locking rib to prevent said blade assembly from being rotated.
17. The blender according to claim 16 , further comprising:
a base having a motor for operating said blender when said blade assembly is mounted on said base, said base having a protrusion;
wherein when said blade assembly is mounted on said base, said protrusion prevents said latch from being depressed to prevent said latch from pivoting said open position so that said latch cannot be unlocked while said blade assembly is mounted on said base.
