A wrench apparatus, comprising:
- a handle portion having a first end and a second end disposed opposite the first end;
- and
- a body portion extending from the first end, the body portion comprising a first gripping portion and a second gripping portion disposed concentric with respect to the first gripping portion,
- wherein the first and second gripping portions are each configured to engage a first closure and a second closure, respectively, of a first container and a second container, respectively, in a press fit manner and remove the first and second closures, respectively, therefrom responsive to the handle portion being rotated with respect to the first and second containers, respectively, wherein the first closure has a plurality of ribs having a first length and the second closure has a plurality of ribs
- wherein the first and second gripping portions are each annular-shaped and have an inner diameter, the inner diameter of the second gripping portion being greater than the inner diameter of the first gripping portion,
- wherein the first gripping portion has a first number of ribs configured to engage the first closure, wherein the second gripping portion has a second number of ribs configured to engage the second closure, wherein the second gripping portion has a first end having a first diameter and a second end having a second diameter greater than the first diameter, wherein the second number of ribs are partially conical-shaped and longitudinally tapered from the first end of the second gripping portion to the second end of the second gripping portion, thereby allowing the second number of ribs to assist with installation of the wrench apparatus onto the second closure,
- wherein each of the first number of ribs has a width and a length, wherein each of the second number of ribs has a width and a length, wherein the width of the first number of ribs is greater than the width of the second number of ribs, wherein the length of the second number of ribs is greater than the length of the first number of ribs,
- wherein the plurality of ribs of the first closure comprises between 27 and 50 ribs, and wherein the first number of ribs is between 20 and 25 ribs in order that the first number of ribs is less than the plurality of ribs of the first closure, thereby allowing the first gripping portion to engage with the first closure via an interference fit,
- wherein the body portion has a tab member and a grooved region, wherein the tab member extends outwardly from the first gripping portion away from the handle portion, wherein the tab member has a top surface, wherein the handle portion has a top surface disposed coplanar with the top surface of the tab member, wherein the grooved region extends inwardly from the top surface of the tab member, and wherein the handle portion has an elongated cavity on a bottom side disposed opposite the top surface of the handle portion.
