Description

Technical Field

[0001] This utility model relates to the field of medicine bottle technology, specifically a medical press-type medicine bottle. Background Technology

[0002] Medicine bottles are plastic or glass bottles formed by blow molding, used to package medicines, liquid medicines, solvents, and chemical reagents. Press-type medicine bottles replace the bottle cap with a press-type liquid pump, making it easier to dispense emulsified medicines or liquid medicines.

[0003] Existing medical press-type dispensing bottles use a press-type liquid pump directly mounted on the bottle. The liquid is dispensed by the pressure difference generated in the pump chamber when pressed. However, the pump chamber has an unlimited pressing structure, and the distance the pump tube moves up and down each time is fixed. This results in a constant amount of medicine being dispensed each time. If the dosage needs to change, the fixed dispensing amount will become redundant, leading to waste of liquid and making it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a medical press-type medicine bottle. Utility Model Content

[0005] The purpose of this invention is to provide a medical press-type dispensing bottle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical press-type dispensing bottle, comprising a container bottle, a pump chamber disposed at the upper part of the container bottle, an internally threaded head fixedly installed on the outer surface of the pump chamber, the container bottle being threadedly connected to the internally threaded head via a threaded opening at its top, the same adjustment mechanism being provided on the inner and outer surfaces of the pump chamber, a main tube being slidably disposed through the middle of the pump chamber, protrusions being fixedly provided on both the left and right sides of the surface of the main tube, a base plate being fixedly installed on the lower outer circular surface of the main tube, a press head being fixedly installed on the upper end of the main tube, and a locking mechanism being provided on the upper surface of the internally threaded head.

[0007] Preferably, the adjusting mechanism includes a rotating ring that is rotatably disposed above the internal thread head on the inner wall of the pump chamber, and an internal thread cylinder is fixedly installed on the lower surface of one end of the rotating ring inside the pump chamber, and a threaded plate is threadedly connected to the inner surface of the internal thread cylinder.

[0008] Preferably, the threaded plate is slidably sleeved on the surface of the main body, and the left and right sides of the threaded plate surface are provided with through grooves that match the size of the protrusions.

[0009] Preferably, the locking mechanism includes circumferentially evenly distributed insertion holes on the upper side of the outer surface of the internal thread head, and a locking pin is inserted into one of the insertion holes.

[0010] Preferably, the locking mechanism further includes a limiting plate fixedly installed on the lower side of the locking pin surface, and the upper end of the locking pin slides through the rotating ring.

[0011] Preferably, a material tube is slidably disposed below the inner surface of the main body via a piston seal, and a spring is fixedly installed on the bottom end of the main body around the material tube.

[0012] Preferably, the bottom end of the spring is fixedly connected to the bottom surface of the pump chamber, the lower end of the material tube penetrates the pump chamber, and the penetration position of the material tube is fixedly connected to the pump chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of an adjustment mechanism, a rotating ring, an internal threaded cylinder, a threaded plate, a main body, a protrusion, and a base plate, allows medical staff to manually rotate the rotating ring, thereby rotating the internal threaded cylinder. Under the limitation of the protrusion, the internal threaded plate will move up and down, adjusting the upper and lower positions of the threaded plate inside the pump chamber. When the main body is pressed down and rebounds, the base plate is limited by the maximum height of the threaded plate, thereby suppressing the upward retraction of the main body. This allows for flexible adjustment and limitation of the rebound position of the main body. The maximum rebound limit height can be changed according to needs, enabling the entire medicine bottle to be squeezed and dispensed quantitatively as needed, avoiding the situation of excessive pressure causing overflow and waste of medicine.

[0015] 2. This utility model, through the setting of a locking mechanism, a socket, a locking pin, and a limiting plate, allows the rotating ring to rotate only when the locking pin is pulled up and moved out of the socket. After the limiting position of the adjusting mechanism is adjusted, the locking pin is inserted into the socket of the nearest corresponding point. At this time, the socket limits the rotation direction of the locking pin, and the locking pin passes through the rotating ring, thus limiting the rotating ring and preventing it from rotating again. This locks the adjustment position of the entire adjusting mechanism, greatly improving the stability of the threaded plate after adjustment and limiting. The limiting plate can prevent the locking pin from being pulled out due to excessive pulling. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a medical press-type dispensing bottle includes a container bottle 1. A pump chamber 2 is disposed on the upper part of the container bottle 1. An internally threaded head 3 is fixedly installed on the outer surface of the pump chamber 2. The container bottle 1 is threadedly connected to the internally threaded head 3 via a threaded opening at its top. The same adjustment mechanism 4 is provided on the inner and outer surfaces of the pump chamber 2. A main tube body 5 is slidably disposed through the middle of the pump chamber 2. Protrusions 6 are fixedly provided on both the left and right sides of the surface of the main tube body 5. A base plate 7 is fixedly installed on the lower outer circular surface of the main tube body 5. A press head 11 is fixedly installed on the upper end of the main tube body 5. A locking mechanism 8 is provided on the upper surface of the internally threaded head 3. The press head 11 is connected to the main tube body 5.

[0023] By adopting the above technical solution, the container bottle 1 can be quickly replaced with the pump chamber 2 by using the threaded connection of the internal thread head 3.

[0024] Furthermore, the adjusting mechanism 4 includes a rotating ring 401 that is rotatably disposed above the internal thread head 3 on the inner wall of the pump chamber 2. An internal thread cylinder 402 is fixedly installed on the lower surface of one end of the rotating ring 401 inside the pump chamber 2. A threaded plate 403 is threadedly connected to the inner surface of the internal thread cylinder 402. The threaded plate 403 is slidably sleeved on the surface of the main pipe body 5, and through grooves matching the size and position of the protrusion 6 are opened on the left and right sides of the surface of the threaded plate 403.

[0025] By adopting the above technical solution, the rotating ring 401 is rotated, thereby causing the inner threaded cylinder 402 to rotate. The internal threaded plate 403 will move up and down under the limit of the protrusion 6, adjusting the upper and lower positions of the threaded plate 403 inside the pump chamber 2.

[0026] When the main tube 5 is pressed down and rebounds, the bottom plate 7 is limited by the maximum height position of the threaded plate 403, which can suppress the upward rebound of the main tube 5. This allows for flexible adjustment and limiting of the rebound position of the main tube 5. The maximum rebound limit height can be changed according to needs, so that the entire medicine bottle can be squeezed and dispensed quantitatively as needed.

[0027] Furthermore, the locking mechanism 8 includes insertion holes 801 evenly distributed around the upper side of the outer surface of the internal thread head 3, and a locking pin 802 is inserted into one of the insertion holes 801; the locking mechanism 8 also includes a limiting plate 803 fixedly installed on the lower side of the surface of the locking pin 802, and the upper end of the locking pin 802 slides through the rotating ring 401.

[0028] By adopting the above technical solution, the upper locking pin 802 is moved out of the insertion hole 801, and only then can the rotating ring 401 rotate to adjust the threaded plate 403.

[0029] After the limit position of the adjustment mechanism 4 is adjusted, the locking pin 802 is inserted into the nearest corresponding hole 801. At this time, the hole 801 limits the rotation direction of the locking pin 802, and the locking pin 802 passes through the rotating ring 401, which limits the rotating ring 401 and prevents the rotating ring 401 from rotating again, thereby locking the adjustment position of the entire adjustment mechanism 4.

[0030] Furthermore, a material pipe 9 is slidably disposed below the inner surface of the main body 5 through a piston seal, and a spring 10 is fixedly installed on the outside of the material pipe 9 at the bottom end of the main body 5; the bottom end of the spring 10 is fixedly connected to the bottom of the inner surface of the pump chamber 2, and the lower end of the material pipe 9 penetrates the pump chamber 2, and the penetration position of the material pipe 9 is fixedly connected to the pump chamber 2.

[0031] By adopting the above technical solution, medical staff use the pressing head 11 to move the main body 5 down along the feed tube 9 and squeeze the spring 10.

[0032] When the main tube 5 moves downward, the piston between it and the feed tube 9 will push out the air inside the main tube 5, generating negative pressure. When the pressing head 11 is released, the main tube 5 will move upward under the action of the spring 10. Under the action of the pressure difference, it will draw in the liquid medicine in the container bottle 1 through the feed tube 9 and finally discharge it through the pressing head 11.

[0033] Working principle: When using this medical press-type dispensing bottle, the medical staff first presses down the pressing head 11 to move the main tube 5 down along the feed tube 9 and squeeze the spring 10. As the main tube 5 moves down, the piston between it and the feed tube 9 pushes out the air inside the main tube 5, creating negative pressure. Releasing the pressing head 11 causes the main tube 5 to move up under the action of the spring 10. Under the pressure difference, it draws the liquid medicine from the container bottle 1 through the feed tube 9 and finally discharges it through the pressing head 11. Depending on the dosage, the medical staff pulls up the locking pin 802 to move it out of the insertion hole 801 and then rotates the rotating ring 401, causing the internal threaded cylinder 402 to rotate. The internal threaded plate 403, limited by the protrusion 6, moves up and down, adjusting the threaded plate 403. After adjustment of the upper and lower positions inside the pump chamber 2, insert the locking pin 802 into the corresponding insertion hole 801. At this time, the insertion hole 801 limits the rotation direction of the locking pin 802. The locking pin 802 passes through the rotating ring 401, thus limiting the rotating ring 401 and preventing it from rotating again. This locks the adjustment position of the entire adjustment mechanism 4. When used next time, the base plate 7 is limited by the maximum height of the threaded plate 403, which can suppress the upward retraction of the main tube 5. This allows for flexible adjustment and limitation of the pop-up position of the main tube 5. The maximum pop-up limit height can be changed according to needs, so that the entire medicine bottle can be squeezed to dispense a quantitative amount of medicine as needed. This is the working principle of the medical press-type medicine bottle.
