SAMPLE COLLECTION KIT INCLUDING CAP HAVING SELECTIVELY MOVABLE SLEEVE
A sample collection system can include a sample collection vessel having a sample collection chamber with an opening configured to receive a sample into the sample collection chamber. The sample collection system can additionally include a selectively movable sleeve valve configured to associate with the opening of the sample collection chamber. The sample collection system can include a sealing cap that is configured to associate with the selectively movable sleeve valve and with the sample collection vessel. The sealing cap can include a reagent chamber having reagent(s) stored therein, and when the sealing cap is associated with the sample collection vessel, the selectively movable sleeve valve opens, dispensing the reagent(s) into the sample collection chamber. When the selectively moveable sleeve associates with the sample collection chamber, an outer sleeve slides relative to an inner vessel, opening the sleeve and dispensing reagent into the sample collection chamber.
1 . A sample collection system, comprising:
a sample collection vessel for receiving a sample;
a sealing cap configured to be removably engaged with the sample collection vessel;
an inner vessel securely engaged with the sealing cap, the inner vessel for storing a reagent, the inner vessel comprising a body, the body having a plurality of raised regions that create a recess that is located between two raised regions, the inner vessel further comprising a fluid vent located at the recess of the body; and
an outer sleeve frictionally engaged with the inner vessel, the outer sleeve slidable longitudinally along the body of the inner vessel, the outer sleeve at a first position covering the fluid vent and at a second position opening the fluid vent, wherein the raised regions enhance a friction force between the outer sleeve and inner vessel.
2 . The sample collection system of claim 1 , further comprising a cap band carried on an exterior surface of the inner vessel, wherein the cap band is made of a softer and more elastic material than the inner vessel.
3 . The sample collection system of claim 2 , wherein the cap band is made of a thermoplastic elastomer, a thermoplastic vulcanizate, or silicone.
4 . The sample collection system of claim 2 , wherein the cap band is compressed between the sealing cap and the inner vessel.
5 . The sample collection system of claim 2 , wherein the cap band is configured to serve as a hard stop for the outer sleeve when the outer sleeve is positioned at the second region.
6 . The sample collection system of claim 1 , wherein the outer sleeve is configured to be pushed by an edge of the sample collection vessel to slide longitudinally from the first position to the second position.
7 . The sample collection system of claim 1 , wherein the outer sleeve comprises an inner layer and an outer layer, and the inner layer is made of a first material and an outer layer is made of a second material, different from the first material.
8 . The sample collection system of claim 1 , wherein the outer sleeve comprises a ridge protruding from an outer surface of the outer sleeve, the ridge is configured to be in contact with a top surface of the sample collection vessel when the sample collection vessel engages with the sealing cap.
9 . The sample collection system of claim 1 , wherein the inner vessel comprises a body characterized as having the first region and the second region, the first and second regions being longitudinal regions of the body and are longitudinally displaced from each other, wherein the fluid vent is located at the first region, and the recess is located at the second region.
10 . The sample collection system of claim 1 , wherein the inner vessel comprises an edge that is configured to be engaged with a recess at the sealing cap.
11 . A cap assembly for removably engaging with a sample collection vessel that is configured to receive a sample, the cap assembly comprising:
a sealing cap configured to be removably engaged with the sample collection vessel;
an inner vessel securely engaged with the sealing cap, the inner vessel for storing a reagent, the inner vessel comprising a body, the body having a plurality of raised regions that create a recess that is located between two raised regions, the inner vessel further comprising a fluid vent located at the recess of the body; and
an outer sleeve frictionally engaged with the inner vessel, the outer sleeve slidable longitudinally along the body of the inner vessel, the outer sleeve at a first position covering the fluid vent and at a second position opening the fluid vent, wherein the raised regions enhance a friction force between the outer sleeve and inner vessel.
12 . The cap assembly of claim 11 , further comprising a cap band carried on an exterior surface of the inner vessel, wherein the cap band is made of a softer and more elastic material than the inner vessel.
13 . The cap assembly of claim 12 , wherein the cap band is made of a thermoplastic elastomer, a thermoplastic vulcanizate, or silicone.
14 . The cap assembly of claim 12 , wherein the cap band is compressed between the sealing cap and the inner vessel.
15 . The cap assembly of claim 12 , wherein the cap band is configured to serve as a hard stop for the outer sleeve when the outer sleeve is positioned at the second region.
16 . The cap assembly of claim 11 , wherein the outer sleeve is configured to be pushed by an edge of the sample collection vessel to slide longitudinally from the first position to the second position.
17 . The cap assembly of claim 11 , wherein the outer sleeve comprises an inner layer and an outer layer, and the inner layer is made of a first material and an outer layer is made of a second material, different from the first material.
18 . The cap assembly of claim 11 , wherein the outer sleeve comprises a ridge protruding from an outer surface of the outer sleeve, the ridge is configured to be in contact with a top surface of the sample collection vessel when the sample collection vessel engages with the sealing cap.
19 . The cap assembly of claim 11 , wherein the inner vessel comprises a body characterized as having the first region and the second region, the first and second regions being longitudinal regions of the body and are longitudinally displaced from each other, wherein the fluid vent is located at the first region, and the recess is located at the second region.
20 . The cap assembly of claim 11 , wherein the inner vessel comprises an edge that is configured to be engaged with a recess at the sealing cap.
