Quantitative drop bottle
(1) technical field amount
The utility model belongs to package with fluid and volume measurement technical field thereof, be mainly used in liquid article such as medicine, food, beverage, health products, flavouring and chemical reagent, preparation packing and quantitatively repeatedly take.
(2) background technology
The tradition drop bottle is by the ground liquid storage bottle with the ground suction pipe with inhale ball assembling all-in-one-piece minim pipette and forms, seals bad, frangible, frosted partly easily by alkali corrosion; The medicine drop bottle mostly is the afraid to speak out bottle of plastics point, cuts sharp mouth portion, and usefulness is dripped in extruding, in case cut off, is difficult to good seal again, quantitatively uses difficulty.
In order to remedy the deficiency of traditional drop bottle, people constantly make improvement, and Chinese utility model patent CN2493211 discloses a kind of dosed administration eyedrops bottle, and its purpose provides a kind of quantitatively accurate eyedrops bottle easy to use; Its content is to be equipped with on bottle stopper and to inhale the measuring pipette that ball links to each other; Its weak point is: inhale and to only depend on caoutchouc elasticity to connect between ball and the suction pipe, ageing of rubber or molten account the two easily loosening in addition throw off separate, breakage; Bottleneck is depended merely on and is used plug seal, does not have the sealingly secure guarantee, easily contaminated, the leakage of medicine.
(3) content of utility model
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and provides a kind of suction bulb pipette in conjunction with firm; Bottleneck Bottle cap spacer screwing hermetic; Soup can repeatedly conveniently take, accurately metering, sealingly secure are reliable, be widely used and desirable quantitative drop bottle that production cost is lower.
The purpose of this utility model can reach by following measure: the utility model is mainly by being assembled as lower device:
A. liquid storage bottle 1, its bottleneck tool external screw thread 3;
B. bottle cap 2, and its end face central authorities leave the bottle cap internal thread 14 that preformed hole 11 and tool and external thread of bottleneck 3 are complementary;
C. pass that preformed hole 11 and bottle cap 2 be assembled together by inhaling the minim pipette that ball 4 and suction pipe 5 are formed.
The purpose of this utility model can also reach by following measure:
The minim pipette of quantitative drop bottle of the present utility model is to be embedded in the inner card cage 13 of inhaling ball 4 by the projection circle 12 with measuring pipette 5 tops to be assembled.This version makes inhales ball and is connected safety with suction pipe firmly, and suction pipe can not move up and down in inhaling ball, therefore can the landing fragmentation, and can not enter yet and inhale ball top influence suction ball imbibition function.
The minim pipette of quantitative dropper of the present utility model from bottom to top passes preformed hole 11 the part bottle cap of bottle cap preformed hole periphery is snapped in the exterior bayonet slot 9 of inhaling ball 4 bottoms, is assembled into one with bottle cap.
The two large divisions of quantitative drop bottle of the present utility model---liquid storage bottle and minim pipette are connected and sealing in the following way: the afterbody of inhaling ball 4 pad 10 that the seal as liquid storage bottle 1 bottleneck and bottle cap 2 that extends, bottle cap internal thread 14 and external thread of bottleneck 3 screwed quantitative drop bottle of the present utility model is assembled into an integral body, thereby realized solid and reliable, security seal, finished the utility model.
For security seal, sanitation and hygiene, quantitative drop bottle of the present utility model easy to carry more can be equipped with safety sheathing cap 7,, can make outer cover cap and bottle cap card get tighter if be provided with the vertical raised item 8 more than three in outer cover cap inboard.
After the optimized technical scheme of quantitative drop bottle of the present utility model is implemented, can provide a kind of suction bulb pipette in conjunction with firm for the user; Bottleneck bottle cap thread spacer screwing hermetic; Soup can repeatedly conveniently take, accurately metering, sealingly secure are reliable, be widely used and desirable quantitative drop bottle that production cost is lower.

(5) specific embodiment
The utility model is further described below in conjunction with accompanying drawing: the preferred scheme of quantitative drop bottle of the present utility model is to constitute by liquid storage bottle 1 with minim pipette two large divisions that bottle cap 2 fits together.One, the bottleneck tool external screw thread 3 of liquid storage bottle 1; Its two, bottle cap 2 tool internal threads 14 and its end face central authorities leave preformed hole 11; Minim pipette is made up of the suction pipe 5 of inhaling ball 4 and being carved with quantitative scale 6, and is embedded in suction ball 4 inner card cages 13 by the projection circle 12 with suction pipe 5 tops and firmly links together; Minim pipette from bottom to top passes preformed hole 11 the part bottle cap of bottle cap preformed hole periphery is snapped in the exterior bayonet slot 9 of inhaling ball 4 bottoms, is assembled into one with bottle cap.Suction ball 4 afterbodys of the quantitative drop bottle of the present utility model flange pad 10 that extends has the dual-seal effect: the first links together bottle cap 2 and the further secure seal of minim pipette, prior function is as the fit sealing pad between the bottleneck of liquid storage bottle 1 and the bottle cap 2, by the rotation bottle cap external thread of bottleneck 3 is cooperated with bottle cap internal thread 14 whole quantitative drop bottle secure seal is assembled into one.For security seal, sanitation and hygiene, quantitative drop bottle of the present utility model easy to carry preferably are equipped with safety sheathing cap 7 more, and be provided with vertical raised item 8 more than six in outer cover cap inboard, it is tighter, more firm that outer cover cap and bottle cap card are got, and is difficult for becoming flexible, and is easy to carry.
