    A closed container opener, particularly a microcentrifuge tube opener (10) is adapted to open a closed container, particularly a microcentrifuge tube (16) comprising a container (30) with an opening (32), and a lid (36) for the container, the lid having a lip projection (38) extending past the outer perimeter of the opening and a downwardly extending annular portion (34) shaped to sealing fit insude the opening. The opener comprises a base (14), having a recess (20) shaped to accept the lip projection, comprising a lower projection (22) below and adjacent the recess; and an upper projection (24) above and adjacent the recess. Both the lower projection and the upper projection are positioned to touch the lip and the lid, respectively. The lid can be moved from the container by positioning the lip in the recess and causing the lower projection to apply pressure to the lip away from the container and, at the same time, causing the upper projection to apply pressure to the tube at a position distant from the lip, in a direction towards the container.

    专利说明:

    This invention relates to openers for closed containers, such as microcentrifuge tubes.
    Microcentrifuge tubes are small plastic tubes, generally with a capacity of 0.4-1.7 cm3 of liquid. They are widely used in biotechnology laboratories for working with radioactively labeled chemicals, and as vessels for storing biochemicals, or for conducting biochemical reactions. They have tight closures with a tab, an example of which is shown in the figures. In general, they are opened by pushing up the cork tongue using your thumb or a regular beer bottle opener.
    The aim of the invention is to improve ease of operation.
    This goal is achieved by the fact that a tube opener designed for microcentrifuge and having a housing with an opening and a stopper with a tongue protruding beyond the outer perimeter of the opening in one direction along an axis located in the center of the stopper when the stopper is installed above the opening and with an annular part located under the tongue for placement in the hole, contains a base having a lower protrusion for engaging the tongue when opening and an upper protrusion intended to rest it in the stopper located between them An extension for the tongue and a groove for placing it, the groove is bounded by a wall, and its axis coincides with the tongue axis, while the wall is designed to stop the tab and is positioned so that it prevents the ring portion and the base from touching when the tab is located in the groove when opening , wherein the plug is set to shift from the tube by positioning the tongue in the recess and applying pressure by the lower lip on the tongue from the tube, while simultaneously applying the upper lip to the tube in the position removed nnom of the tab in the direction towards the tube, wherein the base portion is not annular relates tube when the plug is removed from the tube, and the tab

    located in the notch. The opener may contain a handle connected to the base. The length of the upper lip may be greater than the length of the lower lip. The handle may be located at an angle to the planes of the upper and lower protrusion. The tongue of the tube may have a length greater than the length of the notch.
    Figure 1 shows the discoverer, a general view; Fig. 2 is a sectional view of a row of microcentrifuge and opener tubes; on fig.Z - top view of the upper surface of the tubes and the opener; Fig. 4 is a front view of the base of the opener.
    The opener has a handle 1, having a length of about 5 cm, and a base 2. Handle 1 has such a shape that fits the contours of the lower part of the index finger. The base 2 has a shape closely enclosing the tube 3 for a microcentrifuge, with a semi-oval opening 4 (depth B about 0.5 cm; length C about 1 cm and width D about 1 cm), and generally a rectangular recess 5 (depth E about 0 , 2 cm, width F about 0.7 cm and depth G about 0.2 cm). The base 2 consists of a lower ledge b under the recess 5 and the upper ledge 7. The notch 5 is limited by the wall 8.
    The opener is made of solid plastic material that can be autoclaved, for example acrylic, according to standard technology.
    The opener is designed to open microcentrifuge tubes having a stopper with a protruding tongue, such as tube 3 with stopper 9 having tabs 10. protruding beyond the outer perimeter of the ring portion 1 of the tube shown in the sketches.
    The microcentrifuge tube is made with an opening 12 into which the annular portion 13 of the plug 9 fits snugly. The protruding tongue 10 projects approximately 0.2 cm from the outer perimeter 11 of the tube. The tube 9 is connected by a loop 14 to the tube 3.
    Figures 2, 3 show that in order to open the closed tube 3 for microcentrifuge (figure 2, a), which is in the rack 15 for test tubes, the opener is positioned so that the protruding tab 10 of the stopper is directed towards the recess 5 of the opener, and the upper protrusion 7 is pressed down, as shown by arrow 16, onto the plug 9. The opener is then fed, as shown by arrow 17, towards the tongue 10, until the lower projection b approaches the outer perimeter of the tube 3 (figure 2). The two walls of the upper lip 7 help to ensure that the protruding tongue 10 is positioned to enter the hole 4 and the notch 5 alternately. When the tongue 10 is inside the recess 5, the opener is rotated, as indicated by arrow 18,
    that the lower lip 6 exerts upward pressure on the tongue 10, and the upper lip 7 exerts a slight pressure downward on the plug 9. Thus, the plug 9 is removed from the hole 12
    0 tube 3 (Fig. 2, c). Microcentrifuge tube 3 may be closed by the reverse action indicated by the arrow 19, or by pressing a finger on the stopper.
    The opener can be successfully used when tube 3 is in the operator’s hand, and not in tripod 15. When a lot of tubes 3 are placed in the tube, as shown in FIG. 2, each tube can be opened with the opener
    0 and the other tubes do not interfere with the process.
