Embodiment Construction

[0028] like figure 1 As shown, the sampling bottle of the present invention includes: a bottle body for containing a water sample, a bottle cap buttoned on the upper opening of the bottle body, and a plunger mechanism blocked at the top opening of the bottle cap center;

[0029] The bottle body 1 comprises an upper frustum body and a lower cylindrical body, a bottle mouth is arranged at the top center of the upper frustum body, and a bottle bottom is arranged at the bottom of the lower cylindrical body. The height of the upper frustum body accounts for 1 / 4-1 / 3 of the total height of the bottle body, and the height of the lower cylindrical body accounts for 2 / 3-3 / 4 of the total height of the bottle body. The lower cylindrical body is surrounded by a cylindrical outer wall to form a cylindrical inner cavity, and the inner cavity of the upper frustum body is a truncated cone that transitions to the bottle mouth. The lower edge of the frustum-shaped inner cavity of the upper frus...

Abstract

The invention relates to a special sampling bottle for collecting a water sample containing a volatile substance and an oxygen-sensitive substance. The special sampling bottle structurally comprises a bottle body for accommodating the water sample, a bottle cover covering the upper opening of the bottle body, and a plunger mechanism plugging the top opening in the center of the bottle cover, wherein the plunger mechanism comprises a fixed pipe, a T-shaped padding plug and a protection cap. Due to a special bottle body structure and a special bottle cover structure, the bottle cover and the bottle body can synchronously discharge a certain amount of water in the bottleneck in a buckling process, so that the sampling bottle is not required to be vertical absolutely no matter whether the site is flat or not; after the sampling bottle is full of the water sample, even if certain water-sample-free redundant spaces are retained in the bottleneck, all the redundant spaces other than the water sample in the bottleneck can be discharged during filling type buckling of an inner sealing cover as long as the volumes of the retained spaces are smaller than the extruded volume of the inner sealing cover on the bottle cover; therefore the sampling bottle can be full of the water sample, no redundant space is retained, and sampling can be succeeded at one step.

Description

technical field [0001] The invention relates to a sampling container for water quality research, in particular to a special sampling bottle for collecting water samples containing volatile substances and oxygen-sensitive substances. Background technique [0002] The sampling bottles used in the water quality research process are usually glass bottles, and their shape is generally a narrow-mouth bottle, that is, the bottle body part is a thick-diameter cylindrical shape, the bottle mouth part is a thin-diameter cylindrical shape, and the gap between the bottle body and the bottle mouth The transition part is convex toroidal shape. [0003] Sampling bottles are mostly made of glass, and their disadvantages are: first, they are easily broken during handling and transportation; second, for sample bottles containing water samples, after the bottle mouth is sealed, the inside of the bottle is slightly under pressure. State, this just makes between sample vial and sample vial or b...
