Description

Technical Field

[0001] This utility model relates to the field of solution preparation, and in particular to a detachable weighing cup. Background Technology

[0002] The traditional method for preparing solutions in the biopharmaceutical field involves weighing the required solute using a measuring cup and then pouring the solute into the solvent. Because solute residue can remain in the corner between the bottom and the wall of the measuring cup, it is necessary to rinse the cup after pouring the solute. This traditional method has the following drawbacks: the corner is a difficult area to clean, and simple rinsing is insufficient to remove residual solute, often requiring multiple rinses. This is time-consuming, inefficient, and prone to incomplete rinsing or splashing, leading to significant concentration deviations and posing a substantial quality risk.

[0003] In view of the above problems, it is necessary to study a detachable weighing cup that can avoid solute residue and reduce the number of rinsing cycles. Utility Model Content

[0004] The purpose of this invention is to provide a detachable weighing cup that can avoid solute residue and reduce the number of times it needs to be rinsed.

[0005] To achieve the above objectives, the solution of this utility model is: A detachable weighing cup includes a cup body and a detachable cup bottom; the two ends of the cup body are respectively provided with a cup mouth and a connecting port, and an internal thread is formed on the inner side of the connecting port; the detachable cup bottom includes a cup bottom, a connecting rod connected to the center of the cup bottom, and a rotating base connected to the connecting rod, the cup bottom is provided with an external thread that mates with the internal thread of the connecting port, and the connecting rod and the rotating base are located outside the cup body.

[0006] The two ends of the connecting rod are welded to the bottom of the cup and the rotating base, respectively.

[0007] The rotating base has multiple grooves around its periphery.

[0008] The diameter of the aperture of the cup body gradually decreases from the cup mouth to the connection port.

[0009] The inner wall of the cup body and the bottom surface facing the rim of the cup are both coated with an antistatic coating.

[0010] A handle is attached to the outer wall of the cup body.

[0011] The cup body, cup bottom, connecting rod, and rotating base are made of stainless steel.

[0012] The inner side of the connection port is provided with an internal leakage groove that intersects and communicates with the internal thread, and the end of the internal leakage groove near the cup mouth is closed.

[0013] The outer periphery of the cup bottom is provided with an external leakage groove that intersects and communicates with the external thread, and the end of the external leakage groove near the cup mouth is closed.

[0014] After adopting the above solution, the method of using the detachable weighing cup of this utility model for solution preparation is as follows: First, screw the bottom of the detachable cup to the connection port of the cup body; then, place the detachable weighing cup of this utility model on an electronic balance (with the rotating base against the weighing pan of the electronic balance) and pour the solute into the cup body through the opening, and weigh the mass of the solute by the electronic balance to ensure that the mass of the poured solute meets the requirements; next, place the detachable weighing cup of this utility model above the solvent, and invert the detachable weighing cup of this utility model (i.e., with the opening facing down) so that the solute is poured into the solvent from the opening; next, keep the detachable weighing cup of this utility model inverted above the solvent, and rotate the bottom of the cup by rotating the base to separate the bottom of the detachable cup from the cup body; finally, immerse the detachable cup bottom and the cup body in the solvent for rinsing.

[0015] As can be seen from the above, this invention allows the detachable cup bottom to be separated from the main body after the solute is poured out. This eliminates any cleaning dead zones (i.e., the angle formed between the cup bottom and the main body when they are connected) during subsequent rinsing, enabling easy and effective rinsing of both the main body and the detachable cup bottom. This reduces solute residue on both surfaces and the number of rinsing cycles. It should be noted that this invention involves inverting the detachable weighing cup (i.e., with the opening facing down) when both the solvent is inverted and the detachable cup bottom is separated from the main body. This ensures that solute is less likely to remain on the internal threads of the connection and the external threads of the cup bottom, eliminating the need for multiple rinsing cycles on these threads.

[0022] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0023] like Figures 1 to 5 As shown, this utility model discloses a detachable weighing cup, which includes a cup body 1 and a detachable cup bottom 2; wherein, the two ends of the cup body 1 are respectively provided with a cup mouth 11 and a connecting port 12, and an internal thread 121 is formed on the inner side of the connecting port 12; the detachable cup bottom 2 includes a cup bottom 21, a connecting rod 22 connected to the center of the cup bottom 21, and a rotating base 23 connected to the connecting rod 22. The cup bottom 21 is provided with an external thread 211 that mates with the internal thread 121 of the connecting port 12. The connecting rod 22 and the rotating base 23 are located outside the cup body 1.

[0024] The method of preparing a solution using the detachable weighing cup of this invention is as follows: First, screw the bottom 21 of the detachable cup bottom 2 to the connection port 12 of the cup body 1; then, place the detachable weighing cup of this invention on an electronic balance (with the rotating base 23 against the weighing pan of the electronic balance) and pour the solute into the cup mouth 11 of the cup body 1, and weigh the mass of the solute using the electronic balance to ensure that the mass of the poured solute meets the requirements; next, place the detachable weighing cup of this invention above the solvent, and invert the detachable weighing cup of this invention (i.e., the cup mouth 11 facing down) so that the solute is poured into the solvent from the cup mouth 11; next, keep the detachable weighing cup of this invention inverted above the solvent, and rotate the cup bottom 21 by rotating the base 23 to separate the bottom 21 of the detachable cup bottom 2 from the cup body 1; finally, immerse the detachable cup bottom 2 and the cup body 1 in the solvent for rinsing.

[0025] As can be seen from the above, this invention allows the detachable cup bottom 21 to be separated from the cup body 1 after the solute is poured out. This eliminates the risk of dead angles during subsequent rinsing (i.e., the angle formed between the cup bottom 21 and the cup body 1 when they are connected). This enables easy and effective rinsing of the cup body 1 and the detachable cup bottom 2, reducing solute residue on both and minimizing the number of rinsing cycles. It should be noted that when inverting the solvent and separating the detachable cup bottom 21 from the cup body 1, the detachable weighing cup is inverted (i.e., the cup opening 11 faces downwards). This ensures that the internal thread 121 of the connection port 12 and the external thread 211 of the cup bottom 21 are less likely to retain solute, eliminating the need for multiple rinsing cycles on the internal thread 121 and the external thread 211.

[0026] In this embodiment of the invention, the two ends of the connecting rod 22 can be welded to the cup bottom 21 and the rotating base 23 respectively, so that the connecting rod 22 is stably connected to the cup bottom 21 and the rotating base 23. The circumference of the rotating base 23 is provided with a plurality of grooves 231 for the user's fingers to insert, so that the user can apply force to rotate the rotating base 23; the inner wall of the cup body 1 and the end face of the cup bottom 21 facing the cup mouth 11 can be coated with an antistatic coating (not shown). The antistatic coating can prevent the solute from remaining on the inner wall of the cup body 1 and the end face of the cup bottom 21 facing the cup mouth 11 due to static electricity.

[0027] In an embodiment of this utility model, the outer periphery of the cup bottom 21 is provided with an external leakage groove 212 that intersects and communicates with the external thread 211. The end of the external leakage groove 212 near the cup mouth is closed to prevent solute from entering the external leakage groove 212. When rinsing the cup bottom 21, the external leakage groove 212 allows the solvent to enter and exit the external thread 211 more smoothly. In this way, even if a small amount of solute remains on the external thread 211, the small amount of solute remaining on the external thread 211 can be washed out, avoiding solute residue. Similarly, the inner side of the connection port 12 of the cup body 1 is provided with an inner drain groove 122 that intersects and communicates with the internal thread 121. The end of the inner drain groove 122 near the cup mouth 11 is closed to prevent solute from entering the inner drain groove 122. When rinsing the cup body 1, the inner drain groove 122 allows the solvent to enter and exit the internal thread 121 more smoothly. In this way, even if a small amount of solute remains in the internal thread 121, it can be washed out, avoiding solute residue. In addition, the external thread 211 and the internal thread 121 can also be large-pitch threads, which makes rinsing more convenient.

[0028] In an embodiment of this invention, the aperture of the cup body 1 gradually narrows from top to bottom, resulting in a large aperture at the cup opening 11, which facilitates the pouring and emptying of the solute. A handle 3 may be attached to the outer wall of the cup body 1, allowing the operator to grip and easily move the detachable weighing cup of this invention.

[0029] In embodiments of this invention, the cup body 1, cup bottom 21, connecting rod 22, rotating base 23, and handle 3 can be made of stainless steel, thus providing high strength and resistance to damage. Alternatively, the cup body 1, cup bottom 21, connecting rod 22, rotating base 23, and handle 3 can also be made of other metal or plastic materials that do not react with solvents and solutes.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
