Abstract
Abstract A device used to remove the stem and core from a strawberry is described. This device is useful for quickly and nearly removing strawberry stems and cores in one step. It includes one or more tubular members that are attached to a handle member used to grasp the device. The tubular member is directed through the center of the strawberry until the stem and core are detached from the strawberry. The stem removal device quickly and neatly removes the stem and core from strawberries, while minimizing the wasting of strawberry flesh.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
A strawberry stem removal device particularly configured for removing the stem and core from strawberries, said strawberry stem removal device comprising in combination: a. one or more long, tubular members that are individually inserted through the centers of strawberries; and b. a handle member attached to one end of the tubular member that is used to grasp the device during use; and c. a knob and cam assembly used to vary the diameter of the tubular member.
Claim 2
Dependent Claim
77 words
A strawberry stem removal device particularly configured for removing the stem and core from strawberries, said strawberry stem removal device comprising in combination: a. one or more long, tubular members that are individually inserted through the centers of strawberries; and b. a handle member attached to one end of the tubular member that is used to grasp the device during use; and c. a knob and cam assembly used to vary the diameter of the tubular member.
Claim 3
Dependent Claim
34 words
The strawberry stem removal device as set forth in claim 1 wherein the strawberry has a pointed end wherein the orifice of the tubular member is engaged with the pointed end of the strawberry.
Claim 4
Dependent Claim
37 words
The strawberry stem removal device as set forth in claim 1 wherein the strawberry has a stem wherein the tubular member is inserted through the strawberry center until the stem and core are detached from the strawberry.
Claim 5
Dependent Claim
22 words
The strawberry stem removal device as set forth in claim 1 wherein said tubular member has a longitudinal cut forming overlapping edges.
Claim 6
Dependent Claim
20 words
The strawberry stem removal device as set forth in claim 4 wherein each overlapping edge includes at least one notch.
Claim 7
Dependent Claim
19 words
The strawberry stem removal device as set forth in claim 1 wherein said tubular member is expandable in diameter.
Claim 8
Dependent Claim
26 words
The strawberry stem removal device as set forth in claim 1 wherein said knob and cam assembly are turned causing the tubular member diameter to increase.
Claim 9
Independent Claim
124 words
A method particularly designed for separating the stem and core for the soft flesh of strawberries, said method comprising the steps of: a. grasping the strawberry stem up with one hand; and b. engaging the pointed end of the strawberry with the tubular member orifice of the strawberry stem removal device; and c. inserting the tubular member directly up through the center of the strawberry without a twisting motion; and d. detaching the stem and core from the strawberry by pressure provided by the contact of the tubular member orifice with the underside of the strawberry stem; and e. pulling the stem and core out of the tubular member orifice and discarding it; and f. removing the strawberry from the strawberry stem removal device.
Claim 10
Independent Claim
124 words
A method particularly designed for separating the stem and core for the soft flesh of strawberries, said method comprising the steps of: a. grasping the strawberry stem up with one hand; and b. engaging the pointed end of the strawberry with the tubular member orifice of the strawberry stem removal device; and c. inserting the tubular member directly up through the center of the strawberry without a twisting motion; and d. detaching the stem and core from the strawberry by pressure provided by the contact of the tubular member orifice with the underside of the strawberry stem; and e. pulling the stem and core out of the tubular member orifice and discarding it; and f. removing the strawberry from the strawberry stem removal device.
Claim 11
Dependent Claim
26 words
The method as set forth in claim 8 wherein the step of engaging includes inserting the tubular member orifice into the pointed end of a strawberry.
Claim 12
Dependent Claim
45 words
The method as set forth in claim 8 wherein the step of detaching the stem and core includes inserting the tubular member up through the strawberry center until pressure provided by the contact of the tubular member orifice separates the stem from the strawberry top.
