Description

Technical Field

[0001] The utility model relates to the technical field of press-type volumetric flasks, in particular to a press-type upright viscous liquid volumetric flask. Background Art

[0002] In the medical field, medical fluids are often stored in volumetric flasks for easy portability and use, allowing for the removal of a portion of the liquid by squeezing or pouring it out when needed. However, some viscous liquids, such as ultrasonic coupling agents, are highly viscous and adhere strongly to the walls of the volumetric flask. This often requires considerable force to squeeze out, and a significant amount of residual liquid can remain in the flask, making it difficult to squeeze out and resulting in significant waste.

[0003] When not in use, existing volumetric flasks containing viscous liquids are often placed upside down to save effort when squeezing out liquids, allowing gravity to slowly draw the liquid to the bottle mouth. However, this approach presents several issues: First, the bottle mouth is unhygienic; frequently placed upside down, it can easily contact surfaces like the table, causing contamination; and second, a significant amount of liquid remains in the bottle, wasting resources. To address this issue, we propose a push-button upright volumetric flask for viscous liquids. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a press-type upright viscous liquid volumetric flask. When the volumetric flask is used, the viscous liquid that cannot be pressed out is squeezed out through the residual material extrusion mechanism, thereby avoiding waste of resources and effectively solving the problems in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a press-type upright viscous liquid volumetric flask, comprising a bottle body, a bottle cap mounted on the upper surface of the bottle body, a limiting groove provided inside the bottle body, and a residual material extrusion mechanism;

[0006] The residual material extrusion mechanism includes a screw, a limit block, a sliding seat, a rotating seat, a ball groove, a ball and an anti-slip protrusion. The bottle body is rotatably connected to the screw, the outer surface of the screw is threadedly connected to the sliding seat, the sliding seat is slidably connected to the inside of the bottle body, the lower end of the screw is fixedly connected to the limit block, the limit block is rotatably connected to the inside of the limit groove, the lower surface of the limit block is fixedly connected to the rotating seat, the upper surface of the rotating seat is provided with a ball groove, and the ball groove is rotatably connected with evenly distributed balls, the outer surfaces of the balls are in contact with the grooves on the lower surface of the bottle body, and the outer surface of the rotating seat is provided with evenly distributed anti-slip protrusions. When using the volumetric flask, the viscous liquid that cannot be pressed out is squeezed out through the residual material extrusion mechanism, thereby avoiding waste of resources.

[0007] Furthermore, the residual material extrusion mechanism also includes a sealing ring and a threaded sealing ring. The outer surface of the rotating seat is sleeved with a sealing ring, the outer surface of the sealing ring is in contact with the inner wall of the bottle body, and a threaded sealing ring is provided in the opening of the upper surface of the rotating seat. The inner part of the threaded sealing ring is threadedly connected to the outer surface of the screw rod to improve the sealing performance and prevent the viscous liquid from remaining.

[0008] Furthermore, the upper surface of the bottle body is provided with an internal thread, and the lower surface of the bottle cap is provided with an external thread, and the internal thread and the external thread are threadedly connected to facilitate the installation of the bottle body and the bottle cap.

[0009] Furthermore, a material storage box is provided inside the bottle cap, and a sealing sheet is hingedly connected to the feed port of the bottom wall of the material storage box through a hinge, so as to facilitate squeezing out a small amount at a time.

[0010] Furthermore, the bottle cap is internally slidably connected to a discharge pipe, the outer surface of the discharge pipe is sleeved with a rubber sealing ring, the outer surface of the rubber sealing ring is in contact with the inner wall of the bottle cap, the outer surface of the discharge pipe is fixedly sleeved with a limiting ring, and the outer surface of the discharge pipe is movable sleeved with a spring, which is located between the lower surface of the limiting ring and the bottom wall of the bottle cap, so that the discharge pipe can return to its original position after being pressed.

[0011] Furthermore, a fixing seat is provided on the outer surface of the bottle cap, and the upper end of the fixing seat is rotatably connected to a handle through a rotating shaft. The front and rear walls of the handle are provided with sliding grooves, and the front and rear sides of the discharge pipe are provided with limiting protrusions. The limiting protrusions are slidably connected to the inside of the sliding groove on the same side, which is convenient for pressing out viscous liquid.

[0012] Furthermore, the outer surface of the bottle body is provided with evenly distributed anti-slip protrusions 2, which are convenient for holding during use.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the push-type upright viscous liquid volumetric flask has the following advantages:

[0014] When the viscous liquid cannot be squeezed out, the rotating seat is rotated by the anti-slip protrusion, and the rotating seat drives the screw to rotate through the limit block. The rotation of the screw causes the threaded sliding seat to move upward, squeezing out the remaining viscous liquid. Under the action of the ball groove and the ball, the friction is reduced, making it easier to rotate the rotating seat. The sealing effect of the sealing ring and the threaded sealing ring avoids the residual viscous liquid and saves resources. BRIEF DESCRIPTION OF THE DRAWINGS

A movable sleeve on the outer surface of the discharge pipe 8 is provided with a spring 10. The spring 10 is located between the lower surface of the limiting ring 9 and the bottom wall of the bottle cap 2, and a fixing seat 12 is provided on the outer surface of the bottle cap 2. The upper end of the seat 12 is connected to the handle 13 by a rotating shaft. The front and rear walls of the handle 13 are provided with a slide groove 14. The front and rear sides of the discharge pipe 8 are provided with a limiting protrusion 15, which is slidably connected to the inside of the slide groove 14 on the same side. The outer surface of the bottle body 1 is provided with evenly distributed anti-slip protrusions 16. The staff first pours the viscous liquid into the bottle body 1, and then installs the bottle body and the bottle cap together through the internal thread 4 and the external thread 5. When in use, by squeezing the handle 13 inwards, under the limiting action of the slide groove 14, the limiting protrusion 15 drives the discharge pipe 8 to move downward, and the viscous liquid in the storage chamber 6 is squeezed out. Then, the handle 13 is released, and the discharge pipe 8 returns to its original position through the limiting ring 9 under the action of the rebound force of the spring 10. At the same time, the bottle body 1 is slightly squeezed. Under the action of negative pressure and squeezing, the viscous liquid in the bottle body 1 pushes the sealing plate 7 open, and the storage chamber 6 is filled;

[0022] The excess material extrusion mechanism 3 includes a screw rod 31, a limit block 32, a sliding seat 33, a rotating seat 34, a ball groove 35, a ball 36 and an anti-slip protrusion 37. The bottle body 1 is rotatably connected to the screw rod 31, and the outer surface of the screw rod 31 is threadedly connected to the sliding seat 33. The sliding seat 33 is slidably connected to the inside of the bottle body 1. The lower end of the screw rod 31 is fixedly connected to the limit block 32. The limit block 32 is rotatably connected to the inside of the limit groove 17. The lower surface of the limit block 32 is fixedly connected to the rotating seat 34. The upper surface of the rotating seat 34 is provided with a ball groove 35. The ball groove 35 is rotatably connected with evenly distributed balls 36. The outer surfaces of the balls 36 are in contact with the grooves on the lower surface of the bottle body 1. The outer surface of the rotating seat 34 is provided with evenly distributed anti-slip protrusions 37. The excess material extrusion mechanism 3 also includes The sealing ring 38 and the threaded sealing ring 39 are provided on the outer surface of the rotating seat 34. The outer surface of the sealing ring 38 contacts the inner wall of the bottle body 1. The opening on the upper surface of the rotating seat 34 is provided with a threaded sealing ring 39. The interior of the threaded sealing ring 39 is threadedly connected to the outer surface of the screw rod 31. When the viscous liquid cannot be pressed out, the rotating seat 34 is rotated by the anti-slip protrusion 37. The rotating seat 34 drives the screw rod 31 to rotate through the limit block 32. The rotation of the screw rod 31 causes the threaded sliding seat 33 to move upward to squeeze out the remaining viscous liquid. Under the action of the ball groove 35 and the ball 36, the friction is reduced, which facilitates the rotation of the rotating seat 34. The sealing effect of the sealing ring 38 and the threaded sealing ring 39 avoids the residual viscous liquid and saves resources.

[0023] The working principle of the press upright viscous liquid volumetric flask provided by the present invention is as follows: the staff first pours the viscous liquid into the bottle body 1, and then installs the bottle body and the bottle cap together through the internal thread 4 and the external thread 5. When in use, by squeezing the handle 13 inward, under the limiting action of the slide groove 14, the discharge pipe 8 is driven downward by the limiting protrusion 15 to squeeze out the viscous liquid inside the storage cavity 6, and then the handle 13 is released. Under the action of the rebound force of the spring 10, the discharge pipe 8 is restored to its original position through the limiting ring 9. At the same time, the bottle body 1 is slightly squeezed to Under the action of negative pressure and extrusion, the viscous liquid in the bottle body 1 pushes the sealing piece 7 open and fills the storage chamber 6. When the viscous liquid cannot be squeezed out, the rotating seat 34 is rotated through the anti-slip protrusion 37. The rotating seat 34 drives the screw rod 31 to rotate through the limit block 32. The rotation of the screw rod 31 causes the threaded sliding seat 33 to move upward to squeeze out the remaining viscous liquid. Under the action of the ball groove 35 and the ball 36, the friction is reduced, which makes it easier to rotate the rotating seat 34. The sealing effect of the sealing ring 38 and the threaded sealing ring 39 avoids the residual viscous liquid and saves resources.
