Referring to fig. 1, a bottom-opening bottle 10 according to a preferred embodiment of the present invention is shown. The lower bottle 10 includes a bottle body 100, a liquid inlet pipe 200, a pressing air bag 300, a first cap 400, and a second cap 500.

Referring to fig. 2, the bottle 100 has a hollow structure with a receiving cavity 110. The vial 100 includes opposing first and second ends 120, 130. The sidewall of the first end 120 defines a first opening 121 and a second opening 122 that are communicated with the receiving cavity 110. The first opening 121 and the second opening 122 are disposed at intervals along the circumferential direction of the bottle 100. The sidewall of the second end 130 is opened with a third opening 131 communicating with the receiving cavity 110.

When the lower-mouth bottle 10 is located at the horizontal plane, the first end 120 is the upper end of the bottle body 100, the second end 130 is the lower end of the bottle body 100, and the connection line between the first end 120 and the second end 130 is the vertical direction, so that the first opening 121 and the second opening 122 are both located at the upper end of the bottle body 100, and the third opening 131 is located at the lower end of the bottle body 100. The bottle 100 may be made of glass, wood, stainless steel, or the like. The first opening 121 is a liquid inlet, the second opening 122 is an air pressure balancing opening, and the third opening 131 is a liquid taking opening.

In the present embodiment, the bottle body 100 is a transparent glass bottle. Because the transparent glass has the characteristics of good light transmission, corrosion resistance and the like, the bottle body 100 is made of the transparent glass, so that the bottle body 100 has the advantage of corrosion resistance, the light transmission of the bottle body 100 is better, the amount of liquid in the lower-mouth bottle 10 can be conveniently observed, and the lower-mouth bottle 10 is more convenient to use.

In the present embodiment, the axial end surface of the second end 130 is a plane. Therefore, in general, since the placing table or the work surface for placing the bottom-opening bottle 10 in the laboratory is a horizontal surface, the axial end surface of the second end 130 is set to be a flat surface, so that the contact area between the bottle body 100 and the placing table or the work surface can be increased, and the placing of the bottom-opening bottle 10 can be more stable.

One end of the liquid inlet pipe 200 communicates with the first opening 121. When a large amount of liquid needs to be added into the bottle 10, the end of the liquid inlet pipe 200 away from the bottle body 100 needs to be extended into the external liquid, which is stored in a large container, such as a large barrel, or a large solution tank. Thus, the liquid inlet pipe 200 is used to communicate the containing cavity 111 of the bottle 100 with a large-sized container for containing an external liquid. The liquid inlet pipe 200 may be a hard pipe such as a glass pipe or a metal pipe, or a hose such as a rubber pipe or a plastic pipe.

In this embodiment, the liquid inlet pipe 200 is a rubber pipe. The rubber is used as a high-elasticity polymer material with reversible deformation, is rich in elasticity, and has the characteristics of water resistance, corrosion resistance and the like.

Rubber has elastic characteristic for feed liquor pipe 200 is the hose that can freely bend, thereby makes when the liquid feeding of end opening bottle 10, and the position of placing of end opening bottle 10 is comparatively free, and then makes the use of end opening bottle 10 comparatively convenient.

And rubber has waterproof, corrosion-resistant characteristic for feed liquor pipe 200 also has corrosion resistance, even add alkaline liquid etc. in to the jar 10 of running down, feed liquor pipe 200 also is difficult to be corroded and damaged, has not only prolonged the life of feed liquor pipe 200, has improved the suitability of jar 10 of running down moreover.

The pressing air bag 300 is installed on the liquid inlet pipe 200. Specifically, the liquid inlet pipe 200 includes a main pipe 210 and an installation short pipe 220 disposed on a side wall of the main pipe 210 and communicating with the main pipe 210, and the pressing airbag 300 is installed at one end of the installation short pipe 220 away from the main pipe 210. The pressing bladder 300 is a flexible rubber capsule filled with a medium such as air or water, and elastic action is achieved by utilizing the fluidity of air-compressible box liquid.

The first bottle cap 400 and the second bottle cap 500 can be sealed and covered on the second opening 122 and the third opening 131 respectively to seal the second opening 122 and the third opening 131. The first cap 400 and the second cap 500 may be made of plastic, rubber, or the like.

When a large amount of liquid needs to be added into the accommodating cavity 110, the first bottle cap 400 and the second bottle cap 500 are respectively sealed and covered on the second opening 122 and the third opening 131; then, one end of the liquid inlet pipe 200 far away from the bottle body 100 extends into the external liquid; then, the pressing of the air bag 300 is repeated for a plurality of times, so that the external liquid flows into the receiving cavity 110 through the liquid inlet pipe 200 under the action of the external air pressure, thereby filling the liquid into the bottle 10.

When liquid needs to be taken from the bottle 10 with a lower mouth, the first bottle cap 400 is opened, so that external air enters the accommodating cavity 110 through the second opening 122, and air pressure balance is realized inside and outside the bottle body 100; then, the third opening 131 is opened, so that the liquid in the receiving cavity 110 flows out through the third opening 131 under the action of its own weight, thereby achieving the operation of taking the liquid from the bottom-opening bottle 10.

Specifically, the manner of opening the third opening 131 includes at least the following two ways: first, the second bottle cap 500 is directly removed from the third opening 131; second, the second bottle cap 500 is configured to be opened and closed, and the third opening 131 is opened by directly opening the second bottle cap 500.

From this, when adding a large amount of liquid in the bottle 10 of running down, liquid is in a comparatively airtight environment inflow bottle 10 of running down, has reduced operating personnel at the probability of liquid feeding in-process and liquid contact, has avoided operating personnel to take place liquid and splash and cause the condition of personnel's injury to take place when empting liquid in the bottle 10 of running down, has improved above-mentioned bottle 10 of running down's safety in utilization greatly.

In this embodiment, the second bottle cap 500 includes a cap body 510, a liquid outlet pipe 520, and a water stop clip 530. The cover body can be sealed and covered on the third opening 131. The cover 510 is formed with a coupling hole (not shown) communicating with the third opening 131. The cover 510 may be a bottle stopper that is plugged into the third opening 131 in a sealing manner, or may be a bottle cap that is sealed and fitted in the third opening 131. The outlet pipe 520 is arranged through and hermetically fixed in the connecting hole. One end of the outlet pipe 520 protrudes from the outer surface of the cover 510. Specifically, the outlet pipe 520 is a thin pipe with a small inner diameter, and the water stop clip 530 is mounted on the outlet pipe 520 and located outside the bottle body 100. The water stop clip 530 is used for connecting or cutting off the flow passage of the liquid outlet pipe 520.

When liquid needs to be taken out from the bottom-opening bottle 10, the water-stop clamp 530 is opened to open the third opening 131, and the liquid in the receiving cavity 110 flows out through the third opening 131 and the liquid outlet pipe 520 under the action of its own weight. Because the liquid outlet pipe 520 is a thin pipe with a small inner diameter, the liquid in the accommodating cavity 110 flows out slowly through the liquid outlet pipe 520, so that the control of the liquid taking amount in a laboratory is facilitated, and the liquid taking operation is facilitated; when the liquid is taken out, the water stop clamp 530 is closed, and the third opening 131 can be closed to stop the liquid flowing out.

In the present embodiment, there are a plurality of third openings 131 and a plurality of second bottle caps 500. The plurality of third openings 131 are spaced apart. The plurality of second bottle caps 500 are hermetically covered with the plurality of third openings 131 in a one-to-one correspondence. In the actual use process, an arbitrary second bottle cap 500 can be selected to be opened or a plurality of third bottle caps can be simultaneously opened to take liquid, so that the liquid taking work is more free, and the liquid taking efficiency is improved.

In the present embodiment, there are two third openings 131. The two third openings 131 are spaced apart along the circumferential direction of the bottle body 100. The accommodating chamber 110 is provided with a partition 140 therein to divide the accommodating chamber 110 into a first region 111 and a second region 112. The two third openings 131 are respectively communicated with the first region 111 and the second region 112. The first opening 121 and the second opening 122 are both in communication with the first region 111 and the second region 112, respectively. Specifically, the third opening 131 is located on the same side of the bottle 100 as the first opening 121. Thus, the liquid can be introduced into the first region 111 and the second region 112 through the liquid inlet pipe 200.

In the actual use process, if acidic liquid and the like are added into the bottle 10 with a downward opening, the liquid can be added into the first area 111 and the second area 112 at the same time, when the bottle is available, the two second bottle caps 500 are opened, and liquid is taken through the two third openings 131, so that the liquid taking efficiency is improved, and the liquid taking operation is convenient; if the alkaline liquid is added into the lower mouth, the liquid can be added into the first area 111 only through the first opening 121, and the bottle body 100 is mostly glass bottle, and the alkaline liquid reacts with the glass to block the third opening 131 after long-term storage, so that the service life of the lower mouth bottle 10 can be prolonged by adding the alkaline liquid into the first area 111 only.

Further, in the present embodiment, the first opening 121 and the first region 111 are located on the same side of the bottle 110. One of the second bottle caps 500 is a teflon bottle cap, and the teflon bottle cap can be sealed and covered on the third opening 131 communicated with the first region 111. When it is desired to add an alkaline liquid to the jar 10, the liquid will generally flow directly into the first region 111 through the first opening 121 and will not flow over the screen 140 into the second region 112 for cleaning. Since teflon has excellent corrosion resistance, even if an alkaline liquid is added to the first region 111, the second bottle cap 500 covering the third opening 131 communicating with the first region 111 is not easily corroded and damaged, and the service life of the second bottle cap 500 can be prolonged.

However, since the ptfe material is expensive, if all the second caps 500 are ptfe caps, the manufacturing cost of the bottom-mouth bottle 10 is greatly increased. Therefore, the second bottle cap 500 covering the third opening 131 communicated with the first region 111 is made of polytetrafluoroethylene, so that the service life of the lower-mouth bottle 10 is prolonged while the lower-mouth bottle is ensured to have lower processing cost.

Specifically, the material of the second cap 500 covering the third opening 131 communicating with the second region 112 is the same as the material of the bottle 100.

It is understood that in other embodiments, second vial cap 500 is a teflon vial cap. If there are a plurality of second bottle caps 500, the plurality of second bottle caps 500 are all teflon bottle caps. When in use, even if the liquid contained in the bottle body 100 is alkaline liquid, the second bottle cap 500 is a teflon bottle cap, so that the service life of the second bottle cap 500 can be prolonged.

Specifically, when the second bottle cap 500 includes the cap body 510, the liquid outlet tube 520, and the water stop clip 530, the cap body 510, the liquid outlet tube 520, and the water stop clip 530 located on one side of the first region 111 are made of glass or the like having the same material as the bottle body 100; the cover 510, the outlet pipe 520 and the water stop clip 530 located at one side of the second region 112 are all made of teflon.

Furthermore, in the present embodiment, in the connection direction of the first end 120 and the second end 130, the size of the partition 140 is smaller than the size of the accommodating cavity 110. Therefore, a gap is formed between the partition 140 and the inner wall of the accommodating cavity 110 near the first end 120, so that the first area 111 and the second area 112 are communicated. When the bottle 10 is located on the horizontal plane, the connecting line of the first end 120 and the second end 130 is vertical, so the height of the partition 140 is smaller than the height of the receiving cavity 110. When the acidic liquid is added into the bottle 10, the liquid enters the first area 111 through the first opening 121 until the liquid in the first area 111 flows over the end of the partition 140 close to the first end 120 and enters the second area 112, so that the liquid can be added into the bottle body 100. When the alkaline liquid is added into the bottle 10, the liquid enters the first area 111 through the first opening 121, and the liquid level of the liquid in the first area 111 is lower than the height of the partition 140, so that the alkaline liquid is only stored in the first area. The height of the partition 140 is set to be smaller than that of the receiving cavity 110, so that the use of the lower-mouth bottle 10 is more convenient.

In this embodiment, the bottom-mouth bottle 10 further includes a valve 600. The valve 600 is installed on the liquid inlet pipe 200. When a large amount of liquid needs to be added into the bottle 10, the valve 600 needs to be opened first, so that the liquid outside can enter the bottle 100 through the liquid inlet pipe 200; after the liquid is added, the valve 600 is closed to prevent the liquid from being continuously added into the bottle 100 or the liquid in the bottle 100 from flowing out through the liquid inlet pipe 200. Therefore, the valve 600 is provided, so that the use of the lower-mouth bottle 10 is more convenient.

Further, in the present embodiment, the valve 600 is located between the first opening 121 and the pressing bladder 300. Therefore, as long as the valve 600 is closed, even if the air bag 300 is pressed by mistake, the liquid in the liquid inlet pipe 200 can not enter the bottle body 100; even if the lower-mouth bottle 10 falls down or the like occurs, the liquid in the bottle body 100 does not flow out through the first opening 121. Therefore, the valve 600 is disposed between the first opening 121 and the pressing bladder 300, which effectively improves the reliability of the lower-mouth bottle 10.

In this embodiment, the sidewall of the first end 120 is protruded with a balance pipe 150. The balance tube 150 extends in a direction away from the second end 130. Thus, the balance tube 150 is disposed at an angle with respect to a line connecting the first end 120 and the second end 130. The end of the balance tube 150 away from the bottle body 100 is opened with a second opening 122 communicating with the receiving cavity 110. Therefore, when the lower bottle 10 is positioned on the horizontal plane, the balance tube 150 is inclined upward, so that the probability that the liquid in the storage chamber 110 flows out through the second opening 122 can be reduced, and the reliability of the lower bottle 10 can be improved.

In the present embodiment, the sidewall of the bottle 100 is provided with a scale (not shown) along the direction of the line connecting the first end 120 and the second end 130. When the bottle 10 is located on a horizontal plane, the line connecting the first end 120 and the second end 130 is vertical, so the scale is set along the vertical direction. Due to the arrangement of the scales, an operator can add liquid into the bottle body 100 or can read the volume quantity of the liquid in the bottle body 100 at any time in the ordinary liquid taking process, so that the lower-mouth bottle 10 is more convenient to use.

In the bottle 10 with a lower mouth, when a large amount of liquid needs to be added into the bottle 10 with the lower mouth, the first bottle cap 400 and the second bottle cap 500 are respectively sealed and covered on the second opening 122 and the third opening 131, and then one end of the liquid inlet pipe 200, which is far away from the bottle body 100, is extended into external liquid (namely liquid in large-scale containers such as solution tanks) so that the bottle 10 with the lower mouth forms a closed space; then, the pressing of the air bag 300 is repeated for a plurality of times, so that the external liquid flows into the receiving cavity 110 through the liquid inlet pipe 200 under the action of the external air pressure. From this, when the liquid feeding of tang bottle 10, liquid all flows into tang bottle 10 under a comparatively inclosed environment in, has reduced operating personnel and liquid contact's probability at the liquid feeding in-process, has avoided operating personnel to take place liquid and splash and cause personnel's injured circumstances to take place when empting liquid in tang bottle 10, has improved above-mentioned tang bottle 10's safety in utilization greatly.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
