KINK VALVE ASSEMBLIES

1 . A kink valve assembly, comprising:

a first rigid member;

a second rigid member pivotably coupled to the first rigid member;

an elongate, flexible kink tube having first and second end portions, wherein the kink tube extends though the first and the second rigid members;

a mouthpiece coupled to the first end portion of the kink tube;

a first lock portion coupled to the first rigid member;

a second lock portion coupled to the second rigid member, wherein the second lock portion is configured to releasably engage the first lock portion such that the first and the second rigid members cannot pivot relative to each other; and

an actuator coupled to the first rigid portion or the second rigid portion, wherein the actuator is configured control the engagement of the first and the second lock portions.

2 . The assembly of claim 1 , wherein the first and the second rigid members are pivotable relative to each other from a first position to a second position and from the second position to the first position, and the kink tube is in an open configuration in the first position and in a sealed configuration in the second position.

3 . The assembly of claim 2 , wherein the first lock portion is disengaged from the second lock portion in the first position, and the first lock portion is engaged with the second lock portion in the second position.

4 . The assembly of claim 3 , wherein the actuator is configured such that actuating the actuator causes the second lock portion to disengage from the first lock portion.

5 . The assembly of claim 1 , wherein the first lock portion is integrally formed with the first rigid member, and the second lock portion is integrally formed with the second rigid member.

6 . The assembly of claim 1 , wherein the actuator is movably coupled to the second rigid member.

7 . The assembly of claim 6 , further comprising a biasing element configured to bias the positioning of the actuator relative to the second rigid member.

8 . The assembly of claim 7 , wherein the biasing element is disposed in a housing portion of the second rigid member.

9 . The assembly of claim 1 , wherein the mouthpiece comprises a bite valve.

10 . The assembly of claim 1 , wherein the second end portion of the kink tube is coupled to a drink tube of a hydration bladder.

11 . A kink valve assembly, comprising:

a first rigid member having a first lock portion;

a second rigid member pivotably coupled to the first rigid member;

an elongate kink tube extending though the first and the second rigid members;

a mouthpiece coupled to one end of the kink tube; and

an actuator having a second lock portion and coupled to the second rigid member, wherein the second lock portion of the actuator is configured to releasably engage the first lock portion of the first rigid member such that the first and the second rigid members cannot pivot relative to each other and fluid is prevented from flowing through the kink tube to the mouthpiece.

12 . The assembly of claim 11 , wherein the first and the second rigid members are pivotable between a first position and a second position, the kink tube being in an open configuration in the first position and in a closed configuration in the second position.

13 . The assembly of claim 12 , wherein the first lock portion of the first rigid member is disengaged from the second lock portion of the actuator in the first position, and the first lock portion of the first rigid member is engaged with the second lock portion of the actuator in the second position.

14 . The assembly of claim 11 , wherein the actuator is configured such that actuating the actuator causes the second lock portion of the actuator to disengage the first lock portion of the first rigid member.

15 . The assembly of claim 11 , wherein the actuator is slidably coupled to the second rigid member.

16 . The assembly of claim 11 , wherein the actuator is coupled to a spring that biases the second lock portion of the actuator toward a locked configuration.

17 . The assembly of claim 11 , wherein the first and the second rigid members are pivotable relative to each other to a plurality of indexed positions in which the first and the second rigid members resist pivoting relative to each other.

18 . The assembly of claim 11 , wherein the first lock portion comprises a loop having a laterally extending opening, the second lock portion comprises a radially extending projection, and the projection of the second lock portion is configured to extend into the opening in the first lock portion to releasably engage the loop of the first lock portion.

19 . A hydration assembly, comprising:

a bladder having a drink tube;

a pack configured for holding the bladder; and

a kink valve coupled to the drink tube of the bladder, the kink valve including:

a first rigid member having a first lock portion,

a second rigid member pivotably coupled to the first rigid member,

an elongate kink tube extending though the first and the second rigid members,

a mouthpiece coupled to one end of the kink tube, and

an actuator having a second lock portion and coupled to the second rigid member, wherein the second lock portion of the actuator is configured to releasably engage the first lock portion of the first rigid member such that the first and the second rigid members cannot pivot relative to each other and fluid is prevented from flowing through the kink tube to the mouthpiece.

20 . The assembly of claim 19 , wherein the drink tube of the bladder and the kink tube of the kink valve are integrally formed.
