Ergonomic Hand-Held Device
An ergonomic hand-held device is provided to allow a user to easily apply the necessary force required to install a caps into a vial or test tube. The device includes a handle member that is ergonomically shaped to provide a user with maximum comfort while minimizing any physical problems associated with the use of the hands and wrists continuously in a repetitive motion. The device also includes an engaging projecting member that extends from the handle member. The projecting member includes a flat surface at one end such that when engagement with the cap the flat surface lies substantially flush against a bottom wall of a cavity of the cap. Through this configuration, a user generated force is transferred from the handle member through the projecting member, and to the cap, thereby causing the cap into an opening of the vial for locking the cap into a sealed and closed position with the vial.
1 . An ergonomic hand-held device for installing a cap into engagement with a vial, comprising:
a handle member having a top surface and a bottom surface, said handle member comprising at least one recessed portion; and
a projecting member extending from the bottom surface of the handle member, said projecting member having a flat surface at one end such that when engagement with the cap said flat surface lies at least substantially flush against a bottom wall of a cavity of the cap, wherein force generated by the user is transferred from the handle member through the projecting member, and to the cap, thereby causing the cap to engage into an opening of the vial for locking said cap into a sealed and closed position within said vial.
2 . The hand-held device of claim 1 , wherein said cap comprises an upper and a lower flange extending outwardly around a periphery of a lower section of the cap.
3 . The hand-held device of claim 2 , wherein said vial comprises an inwardly pointed flange extending around an inner periphery of the vial.
4 . The hand-held device of claim 3 , wherein said lower flange of the cap is displaced over and beneath the inwardly pointed flange of the vial such that the inward pointed flange is positioned between the upper and the lower flange of the cap to securely seal the cap into the vial.
5 . The hand-held device 1 , wherein the at least one recessed portion of the handle member is configured to be grasped by the user to apply said force to position the projecting member into engagement in the cavity of the cap.
