Specific embodiment

It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model；Following embodiment is only For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation Novel protection scope.

It is as shown in Figs 1-4 the structural schematic diagram of the reagent bottle of anti-bottleneck leakage, the utility model provides a kind of anti-bottle The reagent bottle of mouthful leakage, including bottleneck 1, body 2 and bottom of bottle 3 are sealedly connected with bottle cap 4, institute by side thread at the bottleneck 3 The sealing ring 8 for being provided in the middle part of bottle cap 4 and cooperating with bottleneck 3 is stated, the first sealing position 5 is provided between the sealing ring 8 and bottleneck 3 With third sealing position 7, the second sealing position 6 is provided between the bottleneck 3 and bottle cap 4, first sealing position 5 is arranged in bottleneck Thread face root and bottleneck outer tip end is arranged on the inside of bottle cap in 8 root of 3 inner tips and sealing ring, second sealing position 6, Third sealing position is arranged in 8 outer wall of 1 internal side wall of bottleneck and sealing ring.

The present embodiment utilizes sealing ring and bottle cap and bottleneck by being provided with the sealing ring with bottleneck cooperation in the middle part of bottle cap 3 sealing positions of cooperation ensure reagent bottle sealability, which is able to bear the negative pressure of 40Kpa by vacuum detecting It leaks hunting test, solving reagent bottle, the hidden danger of bottleneck leakage can occur in air transportion
