Capping-Decapping Tool for Screw-cap Tubes or Bottles

摘要

This document describes a capping-decapping device for screw-capped tubes or vessels. Caps of screw-capped vessels are inserted into an inverted channel. A high-traction surface and a low-friction surface comprise opposite walls. The cap unscrews as it is pushed forward, and is held in the device once unscrewed. The vessel can be recapped by pulling the cap back toward the user. Additional features of the device may be added to improve usability, such as making it easier to open caps of varying diameters or to detect the presence of a cap in the device.

主权项

1. A device for removing and replacing a threaded cap from a vessel comprising:
a. a mounting block with a horizontal surface forming the base of a channel; b. a compression block with one low-friction surface that forms one wall of said channel; c. a high traction surface forming the opposing wall of said channel; d. a means, from a set of spring, elastic band, or flexing element, for forcing said low-friction surface towards the high-traction surface; e. the entrance of said channel is wider than said threaded cap; and f. the depth of said channel is on the order of the height of said threaded cap.
