In one embodiment, the container assembly 10 is adapted for collection, storage and/or transportation of a biological sample or specimen obtained from a patient. In other embodiments, the container assembly 10 is especially suited for collection, storage and/or transportation of a biopsy sample in a preservation solution (e.g., formalin), which can be harmful to a user of the container assembly 10 (e.g., a nurse performing the biopsy, etc.) if it or its fume is inhaled by or otherwise comes in contact with the user. In one embodiment, the container assembly 10 includes a reservoir in which the solution is pre-stored within the container assembly 10 and which is capable of safely releasing the solution into a biopsy storage chamber in the container assembly 10. In other embodiments, the container assembly 10 is adapted for use in collecting, storing and/or transporting other biological samples, either with or without a solution.

In one embodiment, the container assembly 10 includes a container 12 having an upper end 14 and a lower end 16 (see, e.g., FIGS. 1-3 and 5-9). In one embodiment, the container 12 includes one or more connectors 18 formed on an external surface of the container 12 adjacent the upper end 14. In one embodiment, the connectors 18 include one or more threads. In one embodiment, the container 12 includes a chamber 20 (see, e.g., FIG. 5) for receiving a biological sample or specimen therein for storage and/or transportation.

Referring primarily to FIGS. 1, 5, 6, 8 and 9, the container assembly 10 includes a cap 22 configured to be removably attached to the container 12 and close off the chamber 20 in a liquid-tight manner in accordance with one embodiment. In one embodiment, the cap 22 includes an upper movable section 24 and a lower base section 26 which are removably and/or movably attached to each other. In one embodiment, each of the movable and base sections 24, 26 is a monolithically formed or molded as a single piece. In another embodiment, each of the movable and base sections 24, 26 may be formed in multiple pieces, which are then attached to one another by conventional attachment processes.

In one embodiment, the movable section 24 has a top 28, as well as a skirt 30, a retaining member 32 and a plug or sealing member 34, all of which depend from the top 28 (see, e.g., FIGS. 1, 5, 6, 8 and 9). In one embodiment, the skirt 30 has one or more connectors 36 formed in an inner surface wall thereof. In one embodiment, the connectors 36 include one or more threads. In one embodiment, the retaining member 32 is in the form of a cylindrical member having an open bottom end 38. In one embodiment, a trough 40 is formed between the skirt 30 and the plug 34, while a seat 42 (see FIGS. 8 and 9) is formed at a top end of the trough 40 for purposes to be discussed below.

In one embodiment, the movable section 24 has a cylindrical projection 44 projecting upwardly from the top 28 (see, e.g., FIGS. 1, 7, 8 and 9). In one embodiment, the cylindrical projection 44 is a continuation of the retaining member 32, as illustrated in FIGS. 8 and 9. In one embodiment, the cylindrical projection 44 and the retaining member 32 define a reservoir chamber 46 in communication with the bottom end 38 of the retaining member 32 for purposes to be discussed hereinbelow. In one embodiment, the reservoir chamber 46 is closed off at its upper end by a top wall 48, which is connected to the cylindrical projection 44.

In one embodiment, the base section 26 of the cap 22 includes a skirt 50 provided with one or more connectors 52 on an inner surface thereof (see, e.g., FIGS. 1, 6, 8 and 9). In one embodiment, the connectors 52 are configured so as to engage the connectors 18 of the container 12. In one embodiment, the connectors 52 include one or more threads configured to mate with the threads of the connectors 18 of the container 12.

In one embodiment, the base section 26 of the cap 22 includes a ledge member 54 extending radially inwardly from the skirt 50, terminating at an inner annular edge 56 (see, e.g., FIGS. 1, 5-8 and 9). In one embodiment, a cylindrical projection 58 projects from the ledge member 54 and is provided with an open top end 59, as well as one or more connectors 60 on an outer surface thereof. In one embodiment, the connectors 60 of the cylindrical projection 58 are configured so as to engage the connectors 36 of the movable section 24. In one embodiment, the connectors 60 include one or more threads configured to mate with the threads of the connectors 36 of the movable section 24.

In one embodiment, a retaining member 62 depends from the inner annular edge 56 of the ledge member 54 (see, e.g., FIGS. 6, 8 and 9). More particularly, the retaining member 62 includes a generally cylindrical wall 64 projecting downwardly from the inner annular edge 56 and having a bottom end 66. In one embodiment, the retaining member 62 also includes a plug 68 (see, e.g., FIGS. 8 and 9) located substantially coaxially within the cylindrical wall 64 for purposes to be discussed hereinbelow. In one embodiment, a spacer member 70 (see, e.g., FIGS. 6, 8 and 9) connects the bottom end 66 of the cylindrical wall 64 to the plug 68, forming an annular trough 72 between the plug 68 and the bottom end 66 of the cylindrical wall 64, as well as a seat 74 defining a bottom of the trough 72. In one embodiment, the plug 68 is configured to be inserted into the open bottom end 38 of the retaining member 32 of the movable section 24 for the purpose of closing off the open bottom end 38 in a liquid-tight manner. In one embodiment, the plug 68 includes an annular sealing wall 76 (see, e.g., FIG. 9), which projects generally upwardly from the spacer member 70, and a dome member 78, which is connected to the sealing wall 76 for covering up a space formed within the sealing wall 76. In one embodiment, the plug 68 includes a plurality of reinforcing ribs 80 formed on the underside of the dome member 78 and connected to the sealing wall 76 for reinforcing the plug 68 such that the plug 68 is inhibited from buckling when engaging the bottom end 38 of the retaining member 32 of the movable section 24.

In one embodiment, the retaining member 62 of the base section 26 includes a plurality of discharge openings 82 (see, e.g., FIGS. 5, 6 and 9) formed in the cylindrical wall 64 adjacent the bottom end 66, and optionally extending into the spacer member 70, as illustrated in FIG. 6. In one embodiment, the discharge openings 82 are arranged along the periphery of the cylindrical wall 64 and surround the plug 68 for purposes to be discussed hereinbelow.

In one embodiment, the base section 26 includes a plug or sealing member 86 (see, e.g., FIGS. 6, 8 and 9) depending from the ledge member 54. In one embodiment, the plug 86 cooperates with the skirt 50 so as to form an annular trough 88 (see FIG. 9). In one embodiment, the plug 86 and the trough 88 are configured so as to engage and receive the upper end of 14 of the container 12 for closing or sealing off the chamber 20 of the container 12 when the cap 22 is properly attached to the container 12.

In one embodiment, with the movable and base sections 24, 26 of the cap 22 disassembled from one another, the movable section 24 is turned upside down, providing access to the reservoir chamber 46. In one embodiment, a predetermined amount of a desired solution or liquid is poured into the reservoir chamber 46 through the open bottom end 38 of the retaining member 32. In one embodiment, the desired solution can be a preservation solution for preserving a biopsy tissue sample, such as formalin. With the movable section 24 still in its upside-down position to contain the desired solution in the reservoir chamber 46, the base section 26 is attached to the movable section 24 to close or seal off the open bottom end 38 and hence the reservoir chamber 46 of the movable section 24. In one embodiment, the cylindrical projection 58 of the base section 26 is initially inserted into the skirt 30 and rotated such that the connectors 36 of the skirt 30 engage or mesh with the connectors 60 of the cylindrical projection 58. As the cylindrical projection 58 is rotated into the skirt 30, the open bottom end 38 of the movable section 24 is inserted into the trough 72 and receives the plug 68. Likewise, the open top end 59 of the cylindrical projection 58 is inserted into the trough 40 of the movable section 24 and receives the plug 34. In one embodiment, when the movable section 24 is properly assembled with the base section 26, it is positioned in its closed position, in which the open bottom end 38 of the retaining member 32 and the open top end 59 of the cylindrical projection 58 seat against the seat 70 of the base section 26 and the seat 42 of the movable section 24, respectively (see FIG. 8). In this arrangement, the plug 68 and the plug 34 engage the bottom end 38 of the movable section 24 and the top end 59 of the base section 26, respectively, in a liquid-tight manner such that the reservoir chamber 46 forms a reservoir for containing the desired solution therewithin. In one embodiment, due to the sealing engagement between the bottom end 38 of the movable section 24 and the plug 68 (and optionally with the seat 74) of the base section 26 and between the top end 59 of the base section 26 and the plug 34 (and optionally with the seat 42 and skirt 30) of the movable section 24, the desired solution is prevented from leaking out from the reservoir chamber 46 and the cap 22, respectively. In one embodiment, one or more additional sealing mechanisms, such as an O-ring or other sealing members, may optionally be provided (e.g., on the plug 68, the bottom end 38 of the movable section 24, the spacer member 70, the seat 74, and/or the cylindrical wall 64; and on the plug 34, the top end 59 of the base section 26, the seat 42 and/or the skirt 30 of the movable section 24) to ensure a liquid-tight engagement between the movable and base sections 24, 26 and to prevent leakage of the solution from the reservoir chamber 46 or the cap 22. With the movable and base sections 24, 26 properly assembled with one another, the cap 22 is mounted or screwed onto the upper end 14 of the container 12 to complete the container assembly 10.

In use, once a biological specimen, such as a biopsy sample, is obtained, it is placed in the container 12 after the entire cap 22 in its assembled state (i.e., with the movable and base sections 24, 26 properly attached with one another) is removed or unscrewed from same. Thereafter, with the movable and base sections 24, 26 still securely attached to each other, the cap 22 is mounted or screwed onto the upper end 14 of the container 12. In one embodiment, when the cap 22 is properly attached to the container 12, the plug 86 of the base section 26 engages the upper end 14 of the container 12 in a liquid-tight manner and thereby closes off the chamber 20 in a liquid-tight manner. At this point, the movable section 24 is in its closed position, in which the sealing engagement between the movable section 24 and the base section 26 blocks off fluid communication between the reservoir (i.e., the reservoir chamber 46) and the discharge openings 82 such that the solution is contained or retained within the reservoir (see FIG. 8). To release the solution to the chamber 20 of the container 12, the movable section 24 of the cap 22 is rotated so as to partially unscrew it from the lower section 26, breaking the sealing engagement between the bottom end 38 of the retaining member 32 of the movable section 24 and the plug 68 of the base section 26. More particularly, the rotation of the movable section 24 causes it to move in an axial direction to its open position, in which the bottom end 38 of the retaining member 32 is disengaged, at least partially, from the plug 68 of the base section 26 (see FIG. 10), thereby allowing fluid communication between the reservoir chamber 46 and the discharge openings 82 and causing discharge of the solution from the reservoir chamber 46 into the chamber 20 of the container 12 through the discharge openings 82.

In one embodiment, the movable section 24 is partially attached to the base section 26 while the solution is released from the reservoir chamber 46 to the chamber 20. In one embodiment, locking or other mechanisms may be provided on the movable and/or base sections 24, 26 so as to prevent complete dismount of the movable section 24 from the base section 26. Once the solution has been released from the reservoir chamber 46 to the chamber 20, the movable section 24 is tightened onto the base section 26 and to provide a sealing engagement between the movable section 24 and the base section 26 as discussed above so as to prevent leakage of fumes from any solution remaining in the cap 22. Because the base section 26 remains securely attached to the container 12 during this process, the solution released into the chamber 20 and its fume are contained within the chamber 20.

It should be appreciated that the present invention has numerous advantages. For instance, the solution is contained within the reservoir chamber 46 and is discharged directly into the chamber 20 after placement of a biopsy sample, it or its fume is inhibited from coming in contact with a user. In addition, the operation of the container assembly 10 is simplified, i.e., the movable section 24 only needs to be unscrewed slightly and then screwed back on to release the solution into the chamber 20.

It will be understood that the embodiments described herein are merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be included within the scope of the invention, as defined by the appended claims.
