Detailed Description

The present invention will be more clearly and completely described in the following detailed description of the preferred embodiments in conjunction with the accompanying drawings.

Examples

As shown in fig. 1 to 5, the present embodiment provides a cap opener for opening a cap of a container such as an eight-tube PCR container, the eight-tube PCR container includes eight reagent tubes 10, the container 1 of the present embodiment is each reagent tube 10 of the eight-tube PCR container, and the eight-tube PCR container is commonly used. The reagent tube 10 is a cylindrical tube, the reagent tube 10 contains a medical reagent, and the mouth of the tube is provided with a cover 2 to seal the reagent in the tube. Eight closing caps 2 connect gradually the eight that form an organic whole and link the pipe cover, are equipped with boss 11 on the periphery wall of reagent pipe 10.

The lid opener comprises eight lid opening units 8, each lid opening unit 8 comprising an opening 81 and a body 82, the opening 81 being shaped as a U, the opening 81 being adapted to receive a portion of the reagent vessel 10 in a partially enclosed configuration. The body 82 comprises plugs 3 arranged on both sides of the opening 81, the plugs 3 are used for being inserted into the gap between two adjacent reagent tubes 10, and after being inserted, all the plugs 3 are placed on the bosses 11 along the radial direction of the reagent tubes 10, so that the plugs 3 can be clamped on the bosses 11, and a fulcrum required for rotary motion is formed in a partial region where the plugs 3 are overlapped.

The body 82 is adapted to make a rotational movement about a contact point of the tip of the header 3 with the boss 11 as a fulcrum when the header 3 is inserted into the gap, so as to pry and open the cover 2.

This cap opener forms the lever through above-mentioned rotary motion mode between the part that body 82 kept away from the fulcrum and the fulcrum, makes it can pry and open closing cap 2 by less strength, and is laborsaving, and is light easy, has improved the efficiency of uncapping. The risk that reagent in the reagent tube 10 is splashed to pollute or damage the skin due to the fact that the sealing cover 2 is opened by hands is avoided, and the operation is safe and reliable.

As shown in fig. 3 and 4, the cap opener further comprises a head 5 and a handle 4, wherein the head 5 comprises eight cap opening units 8, the handle 4 is connected with the head 5, and the width of the handle 4 is smaller than that of the head 5. Through such width size setting for handle 4 can be made for smallness, is convenient for handheld.

The head portion 5 includes a step 6, and eight cover opening units 8 are provided in a recessed space 7 of the step 6. The lid-opening unit 8 is sunk in the recess space 7 of the step 6 without protruding the surface of the head 5, avoiding interference with other parts during the rotation movement.

Eight units 8 that uncap connect gradually side by side, through the mode that connects gradually side by side, can once rotary motion operation just can open the closing cap 2 of a plurality of reagent pipes 10 simultaneously, further improved the efficiency of uncapping. The cover opener adopts eight cover opening units 8 and is suitable for eight connecting pipes with wide application. However, in other embodiments, the number of the containers 1 may be adjusted according to practical applications and needs, for example, four pipes, or only a single pipe, and the number of the uncapping units 8 may also be adjusted accordingly. The container 1 may also be of other non-tubular shapes and the shape of the opening 81 may be adapted accordingly. In order to open the cover conveniently, the length of the plug 3 can be correspondingly adjusted according to the needs or the size of the container 1 so as to form a longer lever arm of force, and the cover opening operation is easy and labor-saving. The shape and size of the boss can be correspondingly adjusted according to the actual structural requirement, and the shape and the space size of the plug can be correspondingly adjusted according to the shape and the size of the boss so as to ensure that at least part of the plug is overlapped with the boss along the radial direction of the reagent tube to form a fulcrum required for rotary motion.

The openings 81 of the eight decapping units 8 are equal in size. Adopt a plurality of openings 81 that the size equals, can be adapted to the reagent pipe 10 that the size is the same, each reagent pipe 10's power of uncapping is unanimous, convenient operation. Since many common reagent connecting tubes such as the eight connecting tubes are containers 1 having the same size, the lid opener having the openings 81 having the same size has a wide application range.

As shown in fig. 5, the plug 3 is provided with a recessed structure 31 on its surface contacting the boss 11, and the recessed structure 31 is used for receiving a part of the boss 11 to position the plug 3. I.e. when the edge of the projection 11 abuts the edge of the recess 31 during the operational insertion movement, the plug 3 can no longer be inserted, indicating that the depth of the plug 3 is sufficient and that the plug 3 is in place.

The positioning is achieved by providing a recess 31 which ensures that the depth of insertion is not too shallow to pry the closure 2. By adjusting the size of the concave structure 31, the insertion depth can be adjusted to adapt to different sizes of the bosses 11.

Wherein the length of the plug 3 in the insertion direction a is not less than the radius of the reagent vessel 10. Through the length setting, the length of the force arm generating the lever action is larger than the radius of the reagent tube 10, the force arm is not too short, and the cover is opened easily and labor-saving.

The end of each plug 3 is chamfered so that the lid opener can be smoothly inserted into the gap between the reagent tubes 10, and the plug 3 is not so sharp that the surface of the reagent tube 10 is damaged or scratched by the plug 3, thereby protecting the reagent tube 10. The edge of the handle 4 is rounded, and the handle is light and comfortable after being held by hands and is flexible to operate.

As shown in fig. 3, the handle 4 is further provided with a through hole 9. The through hole 9 is formed as a circular hole through which the lid opener can be easily hung and removed.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
