A latch assembly includes a closing panel having an end with a closing panel tab extending therefrom. A clasp lever is pivotally attached to the end of closing panel and forms a space into which the closing panel tab extends. Inner peripheral sidewalls of the clasp lever forming the space allow the clasp lever to rotate around outer peripheral sidewalls of the closing panel tab when the clasp lever pivots around the end of the closing panel. An incessant force component is disposed within the space between the closing panel tab and a rear inner sidewall of the clasp lever and biases the clasp lever to a neutral position with respect to the closing panel. A force applied to an outer surface of the clasp lever against the bias causes the clasp lever to pivot around the end of the closing panel from the neutral position.

1. A latch assembly comprising: a closing panel having a body with a longitudinal axis, a lateral axis, an end with a closing panel tab extending therefrom, and a receptacle having sidewalls formed into the end of the body of the closing panel generally parallel to the longitudinal axis and laterally spaced from each other along the lateral axis, the receptacle laterally adjacent the closing panel tab along the lateral axis;a clasp lever pivotally attached to the end of closing panel by an extension integral with a body of the clasp lever and inserted within the sidewalls of the receptacle of the closing panel, the body of the clasp lever including inner peripheral sidewalls enclosing a space into which the closing panel tab extends, wherein the inner peripheral sidewalls allow the clasp lever to rotate around outer peripheral sidewalls of the closing panel tab when the clasp lever pivots around the end of the closing panel;a helical spring disposed within the body of the clasp lever spaced between the closing panel tab and a rear inner sidewall of the body of the clasp lever and biasing the clasp lever to a neutral position with respect to the closing panel, wherein a force applied to an outer surface of the clasp lever against the bias of the helical spring causes the clasp lever to pivot around the end of the closing panel from the neutral position;a first alignment rod extending from an encasement pocket formed into an inner sidewall of the closing panel tab and inserted into a first end of an aperture of the helical spring;a second alignment rod extending from an encasement pocket formed into the rear inner sidewall of the body of the clasp lever and inserted into a second end of an aperture of the helical spring; anda pin extending through at least a portion of the body of the closing panel, at least one sidewall of the receptacle, and the clasp lever extension disposed within the receptacle for allowing the clasp lever to rotate around the end of the closing panel. 2. The latch assembly of claim 1, wherein the space is open through a front sidewall of the body of the clasp lever thereby allowing access to an outer surface of the closing panel tab. 3. The latch assembly of claim 1, wherein the outer surface of the clasp lever includes ribbing. 4. The latch assembly of claim 2, wherein the outer surface of the closing panel tab includes ribbing. 5. The latch assembly of claim 1, wherein the closing panel is formed as a single body of molded plastic. 6. The latch assembly of claim 1, wherein the clasp lever body is formed a single body of molded plastic. 7. The latch assembly of claim 1, wherein the body of the clasp lever comprises a front portion and a rear portion spaced at an angle by opposing side portions to define a substantially V-shaped profile of the clasp lever. 8. The latch assembly of claim 7, wherein a space is defined through the front portion of the body of the clasp lever to allow access to a surface of the closing panel tab. 9. The latch assembly of claim 8, wherein the space defined through the front portion of the body of the clasp lever is substantially rectangular to all access to a substantially rectangular surface of the closing panel tab. 10. The latch assembly of claim 7, wherein the extension of the clasp lever is integral with the front portion of the body of the clasp lever. 11. A transportation container comprising: a lid;a base;a latch assembly for selectively latching the lid to the base, comprising: a closing panel having a longitudinal axis, a lateral axis, a first end pivotally attached to the lid and a second opposing end including an outwardly extending tab and a pair of inwardly extending receptacles, each receptacle having sidewalls formed in an end of a body of the closing panel generally parallel to the longitudinal axis and laterally spaced from each other along the lateral axis, the pair of inwardly extending receptacles laterally spaced along the lateral axis by a base of the outwardly extending tab, a first alignment rod extending from a pocket formed into a rear sidewall of the outwardly extending tab;a clasp lever comprising: a pair of spaced apart extensions each received within a corresponding receptacle at the second end of the closing panel for allowing the clasp lever to pivot around the second end of closing panel;a plurality of inner sidewalls enclosing a space into which the outwardly extending tab of the closing panel extends for allowing the clasp lever to rotate around outer peripheral sidewalls of the outwardly extending tab of the closing panel when the clasp lever pivots around the second end of the closing panel;a second alignment rod extending from a pocket formed into a rear inner sidewall of the clasp lever; andan outwardly extending hook for engaging a hook on the container base;a helical spring disposed within the space and between the rear sidewall of the outwardly extending tab of the closing panel and the rear inner sidewall of the clasp lever for biasing the clasp lever in a neutral position with respect to the closing panel, a first end of a longitudinal space of the helical spring receiving the first alignment rod and a second end of the longitudinal space of the helical spring receiving the second alignment rod; anda pin extending through a portion of the second end of the closing panel, the sidewalls of each of the pair of inwardly extending receptacles, and the pair of clasp lever extensions within the corresponding receptacles for pivoting the clasp lever from the neutral position in response to a force applied to an outer surface of clasp lever against the bias provided by the helical spring. 12. The transportation container of claim 11, wherein the clasp lever includes a front portion having an aperture therethrough allowing access to an outer surface of the outwardly extending tab of the closing panel. 13. The transportation container of claim 12, wherein the outer surface of the outwardly extending tab includes ribs. 14. The transportation container of claim 11, wherein the outer surface of the clasp lever includes ribs. 15. The transportation container of claim 11, wherein the outwardly extending tab comprises an integral body of molded plastic. 16. The transportation container of claim 11, wherein the clasp lever is formed as an integral body of molded plastic. 17. The transportation container of claim 11, wherein the closing panel is pivotally attached to the lid with a pin. 18. The transportation container of claim 11, wherein at least one of the lid and base of the transportation container is formed of molded plastic. 19. The transportation container of claim 11, wherein the clasp lever comprises a front portion and a rear portion spaced at an angle by opposing side portions to define a substantially V-shaped profile of the clasp lever. 20. The transportation container of claim 19, wherein a space is defined through the front portion of the clasp lever to allow access to a surface of the outwardly extending tab of the closing panel. 21. The latch assembly of claim 20, wherein the space defined through the front portion of the clasp lever is substantially rectangular to allow access to a substantially rectangular surface of the outwardly extending tab of the closing panel. 22. The latch assembly of claim 19, wherein the pair of clasp lever extensions are integral with the front portion of the clasp lever.
