Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dropper bottles, and in particular to a dropper bottle with a valve. Background Art
[0002] A dropper bottle is a packaging bottle with a dropper, which is mainly composed of a dropper, a rubber head and a bottle body. During use, the rubber head is pressed to adjust the air pressure inside the dropper to absorb the liquid in the packaging bottle.
[0003] The traditional dropper bottle is to put the liquid in the bottle body, and then tighten the liquid outlet with a lid to seal the bottle body. When the lid is opened, due to the large discharge hole, the liquid in the bottle will flow out naturally under the action of its own gravity before the dropper is squeezed. In order to prevent this from happening, the liquid outlet hole of some bottles is made very small. Although this can prevent the liquid from flowing out naturally, another phenomenon will also occur. That is, when the dropper is squeezed, because the discharge hole is too small, the liquid will be sprayed out under greater pressure, causing trouble in use.
[0004] See patent document: CN214016430U proposes a dropper bottle, comprising: a bottle body, a rubber dropper head, an outer plug, an inner plug, a bottle body, and a cover, the bottle body is a cylindrical structure with an opening at one end, the lower part of the bottle body is provided with a dripping hole, the rubber dropper head, the outer plug, and the inner plug are movably arranged on the upper part of the bottle body, the cover is movably arranged on the lower part of the bottle body, the rubber dropper head is a nipple-shaped structure with a limit at one end, the rubber dropper head is semi-embedded in the interior of the outer plug, the limit is matched with the annular limit step, the utility model has a simple structure and is easy to operate, the liquid can be dripped out of the bottle body without unscrewing the dropper component, and the use process will not cause secondary pollution to the liquid in the bottle, and because the bottle body is not made of glass material, more surface treatment processes can be performed.
[0005] Although the dropper bottle proposed in the above document can avoid secondary contamination of the liquid, during use, when the dropper bottle is dripping liquid, the above-mentioned problem of the discharge hole being too large or too small causing the liquid to flow out naturally or in a spraying state still occurs.
[0006] See patent document: CN220595692U proposes a dropper bottle, which includes: a bottle body and an inner cover; a dropper is installed in the center of the inner cover, and a scraper is arranged on the periphery of the dropper; the scraper is fixedly connected to a slider above the inner cover by a connecting rod, and the slider can move along the track groove of the inner cover to adjust the opening / closing state of the scraper; the scraper can be moved to an open state so that the outer edge of the scraper fits the inner surface of the bottle body; the scraper can be moved to a closed state so that the scraper can be taken out of the bottle body together with the dropper. The scraper for collecting liquid on the bottle wall in the dropper bottle provided by the utility model can be moved and opened, and it is convenient to scrape the liquid stuck on the bottle wall when it is opened inside the bottle body. It is opened after being taken out of the bottle body, which is convenient for cleaning the scraper and can further collect liquid on the scraper wall.
[0007] Although the dropper bottle proposed in the above document can clean the inside of the bottle, the problem of liquid naturally flowing out or spraying due to the discharge hole of the dropper bottle being too large or too small still exists during use. Therefore, we propose a dropper bottle with a valve to solve the above problem. Utility Model Content
[0008] The utility model provides a dropper bottle with a valve, which solves the problems in the related art that the discharge hole of the dropper bottle is too large, so that the liquid in the bottle flows out due to its own gravity, or the discharge hole is too small, so that the liquid is sprayed out due to a large pressure.

[0010] Furthermore, a first thread is provided on the outer surface of the bottom end of the bottle body, and a second thread is provided on the inner wall of the cover that matches the first thread. The first thread meshes with the second thread, and the user can rotate the cover to mesh the first thread with the second thread, so that the cover can be tightly connected to the bottle body to avoid leakage of liquid inside the bottle body. At the same time, by rotating, it is also convenient for the user to remove the cover from the outer surface of the bottle body, thereby facilitating overall use.
[0011] Furthermore, a scale is provided on the outer surface of the bottle body, and the user can accurately determine the mass of the remaining liquid by comparing the height of the liquid inside the bottle body with the scale, thereby avoiding affecting the subsequent planning and use of the liquid.

Users can quickly master the correct operation method by reading the instruction manual, effectively avoiding damage to the dropper bottle due to improper operation.
[0013] Furthermore, the outer surface of the cover is provided with anti-skid grooves, which can effectively increase the friction between the user's hand and the cover during the cover rotation process, increase the user's grip on the cover, and effectively avoid hand slippage during the rotation process.
[0014] Furthermore, the inner bottom wall of the cover is fixedly connected with a sealing seat, and the bottom end of the cone head contacts the upper surface of the sealing seat, which can effectively seal the bottom end of the cone head and prevent liquid from leaking from the bottom of the cone head.
[0015] The working principle and beneficial effects of the utility model are:
[0016] 1. In the utility model, the liquid in the bottle body flows downward under the influence of its own gravity, and the liquid enters the interior of the valve. It is restricted by the surface tension of the liquid and cannot flow out naturally. The user squeezes the dropper and uses pressure to push the liquid. The liquid enters the interior of the conical head through the through hole and drips out from the interior of the conical head. After use, the dropper is elastically reset to absorb the liquid remaining in the conical head back into the bottle body, thereby preventing the liquid from flowing out naturally. The whole can prevent the liquid in the bottle from flowing out naturally when the dropper is not pressed. The structure is simple, and the liquid can be dripped out by gently squeezing the dropper when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 to Figure 5 As shown, this embodiment proposes a dropper bottle with a valve, including a bottle body 2, and a scale 6 is provided on the outer surface of the bottle body 2. The user can compare the liquid height inside the bottle body 2 with the scale 6 to accurately determine the mass of the remaining liquid, thereby avoiding affecting the subsequent planning and use of the liquid.
[0027] An operation nameplate 7 is fixedly connected to the outer surface of the bottle body 2, and an instruction manual is engraved on the outer surface of the operation nameplate 7. Users can quickly master the correct operation method by reading the instruction manual, and effectively avoid damage to the dropper bottle due to improper operation.
[0028] At the same time, the outer surface of the operating nameplate 7 can be treated with a waterproof coating to prevent the outer surface of the operating nameplate 7 from rusting or other corrosion conditions after contacting the liquid. The waterproof coating can effectively increase the service life of the operating nameplate 7.
[0029] A dropper 3 is installed on the upper surface of the bottle body 2 , a conical head 12 is installed at the bottom end of the bottle body 2 , and a sealing cap 4 is sleeved on the bottom end of the bottle body 2 .
[0030] A first thread 11 is provided on the outer surface of the bottom end of the bottle body 2, and a second thread 8 matched with the first thread 11 is provided on the inner wall of the cover 4. The first thread 11 is meshed with the second thread 8. The user can rotate the cover 4 to make the first thread 11 mesh with the second thread 8, so that the cover 4 can be tightly connected to the bottle body 2 to prevent leakage of the liquid inside the bottle body 2. At the same time, by rotating, it is also convenient for the user to remove the cover 4 from the outer surface of the bottle body 2, which is convenient for the overall use.

[0032] The inner bottom wall of the sealing cover 4 is fixedly connected with a sealing seat 10 , and the bottom end of the conical head 12 contacts the upper surface of the sealing seat 10 , which can effectively seal the bottom end of the conical head 12 to prevent liquid from leaking from the bottom of the conical head 12 .
[0033] The upper surface of the sealing seat 10 is provided with a groove matched with the bottom end of the conical head 12 , so that the bottom end of the conical head 12 can be just inserted into the interior of the sealing seat 10 , thereby achieving a sealing operation of the conical head 12 .
[0034] Example 2
[0035] like Figure 2 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the inner wall of the bottle body 2 is fixedly connected with a buckle ring 9, the bottle body 2 is provided with a valve 1, the upper part of the outer surface of the valve 1 is provided with a cylindrical surface 13, the cylindrical surface 13 and the buckle ring 9 are buckled with each other, so that the bottom of the valve 1 is tightly fitted with the inner wall of the conical head 12, the inner bottom wall of the valve 1 is fixedly connected with a boss 15, and the upper surface of the boss 15 is provided with a through hole 14.
[0036] The valve 1 and the bottle body 2 are installed by snap-fitting, which makes the overall installation more convenient and also facilitates the disassembly of the valve 1, which is convenient and quick, and effectively improves the efficiency when using the dropper bottle.
[0037] During use, the sealing cap 4 is opened, and the liquid in the bottle body 2 flows downward due to its own gravity, and the liquid enters the interior of the valve 1, and contacts the boss 15 inside the valve 1. The liquid is restricted by the surface tension of the liquid and cannot flow out naturally. Then the user squeezes the dropper 3, and the pressure is transmitted to the bottle body 2, and the pressure is used to push the liquid. The liquid enters the interior of the conical head 12 through the through hole 14 and drips out from the interior of the conical head 12. After use, the user releases the dropper 3, and the dropper 3 elastically resets to suck the liquid remaining in the conical head 12 back into the bottle body 2, thereby preventing the liquid from flowing out naturally, thereby solving the problem of the natural outflow or spraying of liquid caused by the discharge hole of the dropper bottle being too large or too small.
