Protective sheath for securing a blade of a cutlery implement
View Patent ↗A protective sheath is provided for removably securing a blade within the sheath. The sheath includes walls forming a cavity to receive the sheath within the cavity. The sheath also includes a concave detent portion having at least one arm for removably and frictionally securing the blade within the sheath so as to prevent inadvertent or unintended removal of the blade from the sheath.
1. A protective sheath for removably securing a blade, the protective sheath comprising:
a unitary body having a proximal end and a distal end and comprising a cavity defined by a first wall, a second wall extending from the first wall, a third wall extending from the second wall, a fourth wall extending from the third wall, the first wall being parallel to the third wall and connecting the fourth wall to the second wall, the second wall connecting the first wall to the third wall, the third wall connecting the second wall to the fourth wall, and the fourth wall connecting the third wall to the first wall;
an end wall at the distal end of the unitary body;
an opening formed proximate the proximal end of the unitary body, the opening being configured to receive a blade into the cavity; and
a curvilinear concave detent disposed in the second wall and defined by a curvature that extends downwardly into the cavity from a perimeter of the curvilinear concave detent toward an inner surface of the fourth wall, the perimeter of the curvilinear concave detent being contiguous with the second wall and extending from a position adjacent to but not contacting the end wall to a position adjacent to but not contacting the opening, the curvilinear concave detent including a first arm and an opposed second arm, the first arm and the opposed second arm each having a terminal edge defining a longitudinal aperture therebetween, wherein the longitudinal aperture is disposed entirely within the curvilinear concave detent and extends longitudinally along a longitudinal axis of the cavity.
2. The sheath of claim 1 , wherein the unitary body is substantially rectangular.
3. The sheath of claim 1 , wherein one of the second wall and the fourth wall includes an extension tab extending from the proximal end of the unitary body and having at least one aperture formed in the extension tab for receiving a cutlery handle securing member.
4. The sheath of claim 3 , wherein the extension tab is laterally offset from one of the second wall and the fourth wall from which the tab extends.
5. The sheath of claim 3 , wherein the extension tab comprises a lateral portion extending substantially transverse from one of the second wall and the fourth wall from which the extension tab extends and a flat portion extending from the lateral portion and substantially parallel to the second wall and the fourth wall from which the extension tab extends.
6. The sheath of claim 1 , wherein the unitary body includes a display tab removably attached to the unitary body extending from the distal end of the unitary body and having formed therein an aperture for placement of the sheath on a display.
7. The sheath of claim 1 , wherein the unitary body includes a guard rail configured to guide the blade into the cavity.
8. The sheath of claim 1 , wherein the longitudinal aperture extends along a center line of the sheath.
