The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
First be understandable that, for liquid sample required in arbitrary field, gas sample and solid sample, can realize collection by the sampling bottle that adopts the utility model to provide, herein for the ease of understanding and explanation, be specifically described as an example of the sampling bottle of collection liquid sample example, more specifically, can also be in environment exploration, describe as an example of the sampling bottle that gathers field water example.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of sampling bottle, comprise bottle 10 and bottle stopper 20, wherein, bottle 10 comprises the bottleneck 11 that is located at its top, bottle stopper 20 comprises interior plug 21, interior plug 21 is filled in the inside of bottleneck 11, its top is positioned at the outside of bottleneck 11, and the also downward bending that extends radially outwardly along bottleneck forms outer plug 23, the medial surface 24 of outer plug 23 is consistent with the shape of the outer wall 13 of bottleneck 11, and be adjacent to the outer wall 13 of bottleneck 11, like this by bottleneck 11 and interior plug 21, the dual coupling of outer plug 23, make bottle stopper 20 be clamped on bottleneck 11 places completely, in the time of sampling transportation, not only can make bottle stopper 20 difficult drop-offs, and the logical sealing property that can also improve in bottle, avoid preferably sample to overflow.
What deserves to be explained is, as stated in the Background Art, in the time of sampling, sampling bottle easily makes overflow or the bottle stopper in bottle easily come off, and prior art, in order to address this problem, is enclosed sealing band in the outside winding one of bottle stopper of sampling bottle conventionally, to improve the sealing property of sampling bottle, but increase labor content so on the one hand, needed on the other hand additionally to buy sealing band, increased cost.Compared to existing technology, the sampling bottle that the utility model embodiment provides is owing to having adopted the bottle plug structure with interior plug, outer plug structure, can comparatively closely be coupled with bottleneck, improve the leak tightness of sampling bottle, not only can avoid at the outside sealing band that is wound around of bottle stopper, but also can avoid buying extra sealing band, thus can reduce labor content, reduce cost.
Drop from bottleneck 11 for fear of bottle stopper 20, can make inwall 12, the outer wall 13 of bottleneck 11 is all frosted, and correspondingly, bottle stopper 20 forms the bottle stopper of ground type, by friction force effect between bottle stopper 20 and bottleneck 11, make bottle stopper 20 firmly jam-pack at bottleneck 11 places.
Certainly, guarantee bottle stopper 20 firmly jam-pack at bottleneck 11 places, also to guarantee bottle stopper 20 can be successfully from bottleneck 11 extract or jam-pack bottleneck 11 in, for example, in the time that the internal diameter of bottleneck 11 diameter from top to bottom diminishes gradually, the inwall 12 of bottleneck 11 forms intilted inclined-plane from top to bottom, form the structure of back taper at the inwall 12 of bottleneck 11, be adjacent to the inwall 12 of bottleneck 11 due to the lateral surface 22 of interior plug 21 simultaneously, therefore in, the lateral surface 22 of plug 21 forms intilted inclined-plane from top to bottom accordingly, is conducive to like this bottle stopper 20 and extracts or jam-pack.
In the time that the external diameter of bottleneck 11 diameter from top to bottom becomes large gradually, the outer wall 13 of bottleneck 11 forms outward-dipping from top to bottom inclined-plane, form like this structure of taper at the outer wall 13 of bottleneck 11, be adjacent to equally the outer wall 13 of bottleneck 11 due to the medial surface 24 of outer plug 23, because filling in addition, 23 medial surface 24 is corresponding forms outward-dipping from top to bottom inclined-plane, be so more conducive to bottle stopper 20 from bottleneck 11 extract or jam-pack bottleneck 11 in.
In the time that the inwall 12 of bottleneck 11 is inclined-plane, in the manufacture craft of sampling bottle, also help the demoulding in addition, optimize manufacture craft.
Continue to consult Fig. 1 or Fig. 2, the plug handle 25 that can also be provided with in the center, upper end of interior plug 21, wherein fills in the structures such as handle 25 is cylindrical projection, cylindroid projection or rectangular preiection.Take plug handle to realize extracting of bottle stopper or jam-pack by hand.Be convenient to personnel's operation.
In the time that the internal diameter of bottleneck 11 diameter from top to bottom diminishes gradually, can also make the inwall 12 of bottleneck 11 form slightly inwardly protruded curved surface, accordingly, the curved surface of the lateral surface 22 of interior plug 21 for slightly caving inward, so more be conducive to improve the leak tightness of sampling bottle, this is because the drop in bottle always inevitably splashes between the lateral surface 22 of interior plug 21 and the inwall 12 of bottleneck 11, now the structure of curved surface can slow down the flowing velocity of drop, make flowing slowly of drop, and can under the effect of gravity, flow back in bottle.It should be noted that, under the effect of curved-surface structure, most of drop between the lateral surface 22 of interior plug 21 and the inwall 12 of bottleneck 11 can turn back in bottle, although also have sub-fraction to go out along surface current from bottleneck 11, but compare the amount of liquid returning in bottle, the amount of liquid of this part outflow is almost little, even negligible, on improving the not tangible impact of leak tightness of sampling bottle.
Interior plug 21 fill in bottleneck 11 interior after, its height of filling in is greater than inwall 12 height of bottleneck, in, the bottom of plug 21 slightly extend into the inside of bottle 10, can guarantee like this can all be adjacent between the inwall 12 of bottleneck 11 and the lateral surface 22 of bottle stopper 20, in the time of liquid sloshing in bottle, the drop splashing can first be beaten the bottom at interior plug 21, and under the effect of antagonistic force, the drop splashing can turn back to again in bottle, avoid more drop to flow between the lateral surface 22 of interior plug 21 and the inwall 12 of bottleneck 11, further improve the sealing property of sampling bottle.
For the height of outer plug 23, it is highly less than outer wall 13 height of bottleneck, this is because have transition face between the bottom of bottleneck 11 and body, if the height of outer plug 23 is greater than outer wall 13 height of bottleneck, the bottom of outer plug 23 can be interfered with this transition face, and the upper of the end face of bottle stopper 20 inside and bottleneck 11 produce gap along between face, affect the sealing property of sampling bottle.Therefore 23 height is filled in and is at least less than or equals the height of bottleneck outer wall 13 by the present embodiment China and foreign countries, and preferably, the height of outer plug 23 is less than outer wall 13 height of bottleneck 11.
Conventionally the sample in sampling bottle also will carry out follow-up test, and sample is necessary for the sample that is not subject to ectocine, to guarantee the accurate of test.Sampling bottle will guarantee that extraneous air can not enter in bottle for this reason, specifically can realize by seal ring is set, as shown in Figure 3, the lateral surface 22 of interior plug 21 and and the inwall 12 of bottleneck 11 between seal ring 30 is set, particularly, be provided with annular groove (not noting in figure) at the lateral surface 22 of interior plug 21, be provided with seal ring 30 in annular groove, the outer ring face of seal ring 30 is adjacent to the inwall 12 of bottleneck 11.
It should be noted that, although also use seal ring in the present embodiment, because sealing circle is enclosed within on bottle stopper, therefore bottle stopper and seal ring can be can be used as to a global facility and buy, compare that separately to buy the cost of bottle stopper and seal ring lower.
Because the upper end of bottleneck 11 is nearest far from the external world, therefore, in order further to prevent that outside air from entering in bottle, the position of seal ring 30 is located at the upper end in bottleneck 11 in the present embodiment, and the upper surface of seal ring 30 is flushed along face with the upper of bottleneck 11.
In addition, in the time that seal ring 30 is positioned at the upper end of bottleneck 11, the lengthening distance of the lower surface of seal ring 30 and bottleneck 11 bottoms, when drop in bottle splashes between the lateral surface 22 of interior plug 21 and the inwall 12 of bottleneck 11, extend the flow path of drop, under the effect of gravity, drop can just flow back in bottle again in the position that does not also arrive seal ring 30, so also can improve the leak tightness of sampling bottle.
For the size of seal ring 30, the thickness of seal ring 30 is about 1/2nd of interior plug 21 height, and seal ring 30 is about 1/3rd of interior plug 21 diameters along its width radially.Certainly herein also only as optional scheme, be not limited to this, concrete size also will be made restriction according to the size of bottle, bottle stopper.
Above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
