Description

Technical Field

[0001] This utility model belongs to the technical field of opening sealed container devices, and relates to an opening device for a hazardous chemical reagent bottle. Background Technology

[0002] In laboratory work, volatile hazardous chemical reagents are typically stored in reagent bottles with double-necked caps. The double-necked design includes a conical inner cap and an outer screw cap to create a double seal, which, combined with a PTFE gasket, ensures zero leakage of the reagent even when the internal pressure changes.

[0003] However, for laboratory staff, prying open the inner cap by hand is difficult and poses significant safety hazards: First, the inner cap usually fits tightly to the reagent bottle, and opening it by hand can easily injure the fingers; second, without effective securing measures, the reagent inside the bottle may splash out the moment the inner cap is opened; third, if the reagent bottle contains highly corrosive or other toxic and harmful substances, opening the inner cap by hand will significantly increase the safety risks for laboratory personnel. Using tools such as scissors or tweezers can lead to unstable opening, damage to the inner cap, or damage to the tools themselves.

[0004] Therefore, developing a device that can safely and conveniently open the inner and outer caps of hazardous chemical reagent bottles to solve the problems of difficulty in opening, easy splashing of reagents, and high safety risks in the existing technology is an urgent technical need to be addressed.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] See Figures 1-5This embodiment provides a cap-opening device for hazardous chemical reagent bottles. The cap-opening device includes a hinged housing 10, a reagent bottle fixing assembly 20, and a cap-opening assembly. The reagent bottle fixing assembly 20 is used to fix the reagent bottle inside the hinged housing 10 and includes two hinged limiting members 22. The two hinged limiting members 22 move towards each other in the horizontal direction to form a limiting working state, and move in opposite directions to form a limiting working released state. The two ends of the two hinged limiting members 22 are respectively mounted on the hinged housing. The side wall of the hinged box 10; the cap opening assembly enters the box through the top of the hinged box 10 to open the reagent bottles inside the box 10; the cap opening assembly includes an inner cap opening member 30, which is scissor-shaped and includes two first clamping arms 31 hinged by a first pivot 32; the clamping ends of the first clamping arms 31 form arc-shaped embedded clamping parts 33, which are used to insert into the gap between the inner cap protrusion and the bottle mouth to pull out the inner cap. The cap opening device described in this application is safe and convenient to operate, and can be adapted to various models of reagent bottles and reagent bottle inner caps, providing a strong guarantee for the efficient and safe use of hazardous reagents in the laboratory.

[0046] The hinged enclosure 10 makes the entire opening process relatively closed, which can effectively prevent hazardous chemicals from splashing during the opening process and avoid damage to the skin and clothing of the experimental personnel; at the same time, when handling toxic and volatile reagents, it can significantly reduce the inhalation of harmful gases by the operators and improve the protection level of the operation process.

[0047] The reagent bottle fixing assembly 20 limits the opening and closing of the reagent bottle through the opening and closing limiting member 22, so that the reagent bottle fixing assembly 20 can be adapted to various models of reagent bottles. It has a wide range of applications and effectively avoids the risk of splashing caused by laboratory personnel directly contacting the reagent bottle, further ensuring operational safety.

[0048] The inner cap opening component 30 achieves clamping and releasing of the clamping end through two hinged first clamping arms 31, which can be adapted to reagent bottle caps of various diameters; during the first clamping, the arc-shaped embedded clamping part 33 is inserted into the gap between the protruding edge of the inner cap of the reagent bottle and the bottle mouth, and then the first clamping arm 31 is pulled to open the inner cap.

[0049] In a specific embodiment, such as Figures 6-7As shown, the reagent bottle 40 in this application includes a bottle body 44, a bottle mouth 43, an inner cap 42, and an outer cap 41. The inner cap 42 is fitted onto the bottle mouth 43 and sealed by an interference fit. The end of the inner cap 42 away from the bottle mouth 43 protrudes to form an inner cap protruding edge 421. The outer cap 41 is fitted onto the bottle mouth 43 and sealed by a threaded connection. The inner cap protruding edge 421 ensures that the inner cap 42 is confined to the bottle mouth 43, preventing the inner cap 42 from falling into the bottle body 44. During clamping, the arc-shaped embedded clamping part 33 is inserted into the gap A between the inner cap protruding edge 421 and the bottle mouth 43.

[0050] In a specific embodiment, such as Figure 1 As shown, the two opposite side walls of the hinged box 10 have several height positioning holes 12 for mounting the reagent bottle fixing assembly 20. In a... Figure 1 In the specific embodiment shown, any height positioning hole 12 on any side wall is positioned opposite to a height positioning hole 12 on the other side wall.

[0051] In this application, the relative arrangement refers to the two height positioning holes 12 being at the same height relative to the bottom of the opening and closing box 10, and at the same distance relative to the adjacent side wall located on the side wall.

[0052] In a more specific embodiment, such as Figures 1-3 As shown, the reagent bottle fixing assembly 20 also includes a telescopic positioning member 21. One end of the telescopic positioning member 21 is threadedly connected to the opening and closing limiting member 22, and the other end passes through the height positioning hole 12. The telescopic positioning member 21 drives the opening and closing limiting member 22 to move horizontally by telescopic movement, so as to abut against the neck of the reagent bottle 40 or release the limiting position.

[0053] In a further specific embodiment, such as Figures 1-3 As shown, the telescopic positioning member 21 is a telescopic sleeve structure that drives the opening and closing limiting member 22 to move in the horizontal direction through telescopic movement. The telescopic sleeve structure occupies little space, is easy to operate and manufacture, and is suitable for application scenarios with limited operating space in this application.

[0054] In a more specific embodiment, such as Figures 1-3 As shown, the telescopic positioning member 21 includes an inner cylinder 213, an outer cylinder 215 sleeved outside the inner cylinder 213, and a locking screw 214 that penetrates the outer cylinder 215 and abuts against the inner cylinder 213 to lock the telescopic positioning member 21 in its telescopic state. In a... Figures 1-3In the specific embodiment shown, the inner cylinder 213 has an abutment groove for the locking screw 214, and the outer cylinder 215 has a threaded area that matches the locking screw 214. When it is necessary to adjust the telescopic positioning member 21, the locking screw 214 is unscrewed to release the inner cylinder 213. After adjusting the telescopic positioning member 21 until the opening and closing limiting member 22 abuts against the bottleneck of the reagent bottle 40, the locking screw 214 is tightened to abut against the abutment groove of the inner cylinder 213 to achieve locking.

[0055] In a more specific embodiment, such as Figures 1-3 As shown, the telescopic positioning member 21 has a protruding mounting and limiting part 211 at one end away from the coupling limiting member 22. When the telescopic positioning member 21 passes through the height positioning hole 12, the mounting and limiting part 211 limits the height of the telescopic positioning member 21, and rotating the mounting and limiting part 211 rotates the telescopic positioning member 21.

[0056] In a more specific embodiment, such as Figures 1-3 As shown, the telescopic positioning member 21 has a first threaded section 212 formed at one end near the mounting limiting part 211 for matching the height positioning hole 12.

[0057] In a more specific embodiment, such as Figures 1-3 As shown, the opening and closing limiting member 22 has a mounting hole that matches the telescopic positioning member 21, and the end of the telescopic positioning member 21 near the opening and closing limiting member 22 has a second threaded section 216 for matching the mounting hole. The opening and closing limiting member 22 and the telescopic positioning member 21 are movably connected through the mounting hole and the threaded matching of the second threaded section 216.

[0058] In a specific embodiment, such as Figure 1 As shown, the top of the hinged box 10 has a connection port for the opening assembly to pass through.

[0059] In a more specific embodiment, such as Figure 4 As shown, the inner cover opening member 30 also includes a first sealing connector 34, which is sleeved on the first clamping arm 31, and its bottom has a threaded structure for connecting with the connection port. In a case like Figure 1 and 4 In the specific embodiment shown in ~5, the inner wall of the connection port is formed with threads, and the bottom of the first sealing connector 34 protrudes with a threaded structure that matches the connection port to achieve sealing.

[0060] In a further embodiment, such as Figure 4As shown, the first sealing connector 34 is a silicone seal or a rubber seal. The first sealing connector 34 is a silicone seal or a rubber seal, so that when no external force is applied to the first clamping arm 31, the first clamping arm 31 is limited to a certain height and the device remains sealed; when an external force is applied to the first clamping arm 31, the first clamping arm 31 rotates or moves axially through the first sealing connector 34.

[0061] In a more specific embodiment, such as Figure 1 and 5 As shown, the cap opening assembly includes an outer cap opening member 50, which is scissor-shaped and includes two second clamping arms 51 hinged by a second pivot 52; the clamping ends of the second clamping arms 51 are formed with arc-shaped external clamping parts 53, which are used to abut against the outer cap 41 of the reagent bottle.

[0062] In a further embodiment, such as Figure 1 and 5 As shown, the outer cover opening component 50 further includes a second sealing connector 54, which is sleeved on the second clamping arm 51, and its bottom has a threaded structure for connecting to the connection port. The second sealing connector 54 is a silicone seal or a rubber seal. The second sealing connector 54 is a silicone seal or a rubber seal, so that when no external force is applied to the second clamping arm 51, the second clamping arm 51 is limited to a certain height and the device remains sealed; when an external force is applied to the second clamping arm 51, the second clamping arm 51 rotates or moves axially through the second sealing connector 54.

[0063] In a further embodiment, such as Figure 1 and 5 As shown, the arc-shaped external clamping part 53 forms an anti-slip texture 531. In one specific embodiment, the anti-slip texture 531 is serrated. The anti-slip texture 531 improves the stability of the arc-shaped external clamping part 53 when clamping the outer cover 41.

[0064] In a further embodiment, such as Figure 1 and 5 As shown, the second clamping arm 51 has a handle formed away from the clamping end. The handle makes it easier to open and close the second clamping arm 51.

[0065] In a specific embodiment, such as Figure 1 As shown, the working side of the opening and closing limiting member 22 has a limiting groove 221 for limiting the neck of the reagent bottle 40.

[0066] In a specific embodiment, such as Figures 1-2As shown, in the limiting working state, the two opening and closing limiting members 22 move towards each other until they abut against the neck of the reagent bottle 40.

[0067] In a specific embodiment, such as Figures 1-2 As shown, when the limiting operation is released, the two opening and closing limiting members 22 move in opposite directions until the limiting of the reagent bottle 40 is released.

[0068] In a specific embodiment, such as Figure 4 As shown, the first clamping arm 31 has a handle formed away from the clamping end. The handle makes it easier to open and close the first clamping arm 31.

[0069] In a specific embodiment, such as Figure 4 As shown, the arc-shaped embedded clamping part 33 is in the form of a sheet or strip, and an embedding edge is formed on the inner side of the sheet or strip. The embedding edge refers to the fact that the thickness of the sheet or strip gradually decreases along the working direction. The embedding edge makes it easier for the arc-shaped embedded clamping part 33 to be embedded in the gap A between the protruding edge 421 of the inner cap of the reagent bottle and the bottle mouth 43, so as to open the inner cap 42 subsequently.

[0070] In a specific embodiment, such as Figure 1 As shown, the hinged box 10 also includes a door 11. The door 11 is opened and closed to place or remove the reagent bottle 40 and to adjust the reagent bottle fixing assembly 20.

[0071] In a specific embodiment, such as Figure 1 As shown, the hinged box 10 is a transparent box. In a... Figure 1 In the specific embodiment shown, the hinged box 10 is selected from one of acrylic, PVC, and PET boxes. The transparent box makes the entire opening process visible, allowing researchers to observe the status of the components and reagent bottles inside the hinged box 10 for better operation of the opening device.

[0072] In a like Figures 1-7 The specific lid-opening device shown includes the following steps in its operation:

[0073] 1) Open the door 11 and put the reagent bottle 40 that needs to be opened into the hinged box 10;

[0074] 2) Based on the height of the reagent bottle 40, insert the telescopic positioning piece 21 into the height positioning hole 12 at the corresponding position, and connect the opening and closing limiting piece 22 through the second threaded section 216, so that the limiting groove 221 corresponds to the height of the bottleneck of the reagent bottle 40.

[0075] 3) Adjust the inner cylinder 213 and outer cylinder 215 of the telescopic positioning component 21 until the limiting groove 221 is tightly attached to the neck of the reagent bottle 40. Then rotate the locking screw 214 to lock the telescopic positioning component 21 in its telescopic state, thereby fixing the reagent bottle 40.

[0076] 4) If the reagent bottle 40 includes an inner cap 42 and an outer cap 41, the outer cap opening piece 50 is first connected to the connection port at the top of the opening and closing box 10 by the second sealing connector 54.

[0077] 5) The second clamping arm 51 passes through the second sealing connector 54 and moves vertically until the arc-shaped external clamping part 53 reaches the corresponding height of the outer cover 41. Then, the arc-shaped external clamping part 53 is closed by controlling the handle until the outer cover 41 is clamped. The second clamping arm 51 is rotated and pulled to open the cover.

[0078] 6) Rotate the second sealing connector 54 to separate the outer cover opening part 50 from the opening and closing box 10, and then replace the inner cover opening part 30;

[0079] 7) The inner cap opening component 30 is threadedly connected through the first sealing connector 34. The first clamping arm 31 passes through the first sealing connector 34 and moves vertically to the arc-shaped embedded clamping part 33 at the height corresponding to the gap A between the inner cap protrusion 421 and the bottle mouth 43. Then, the arc-shaped embedded clamping part 33 is closed by controlling the handle until it is embedded in the gap A between the inner cap protrusion 421 and the bottle mouth 43. The first clamping arm 31 is rotated and pulled to open the cap.

[0080] This invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0081] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model.
