Description

Low-residual reagent bottle

Technical field

The utility model is relevant with liquid containing container, particularly a kind of low-residual reagent bottle that adopts hollow blow molding process to produce.

Background technology

The Main Function of low-residual liquid container is to make the liquid of final residue in container minimized in specific method of getting liquor situation.At present, low-residual reagent bottle is mostly the wide-mouth bottle of Shooting Technique moulding, as shown in Figure 1 and Figure 2, its body 1 comprises outside support section 11 and inner liquid storage part 12, the internal diameter of the liquid storage part 12 of the internal diameter of bottleneck 2 and body 1 is suitable, will cause like this bottle cap larger than the size of body, bottle cap does not have the solution of rationally placing after opening simultaneously, and bottle cap is covered on bottleneck again very likely to polluting in bottle.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of low-residual reagent bottle, and designs simplification not only can steadily be placed, and can stop in reagent bottle contaminated.

For solving the problems of the technologies described above, the low-residual reagent bottle that the utility model provides, the bottle that comprises a bottle cap and a hollow blow molding, described bottle comprises bottleneck, body and the bottle end, the vertical section at the described bottle end is taper or class taper, the internal diameter of described bottleneck is less than the internal diameter of body, at the bottom of described bottle cap is sleeved on bottle before reagent bottle filling liquid on, and turn-knob is arranged on bottleneck after reagent bottle filling liquid.

Wherein preferred, the inside of described bottle cap has screw thread and interior envelope lip, and when bottle cap is arranged on bottleneck, the outer wall of interior envelope lip contacts with the top inner wall of bottleneck.

Further, the bottle end of described class taper, comprises cylindrical section and contraction section, and the internal diameter of described cylindrical section is less than the internal diameter of body, and described contraction section has the inner fovea part to downward-extension.

Better, in the time of at the bottom of described bottle cap is arranged on bottle, between the inside top surface of bottle cap and the bottom outer wall at the bottle end, there is a gap.

Low-residual reagent bottle of the present utility model have be narrower than body bottleneck, reduce residual taper or class conical flask at the bottom of and hold dual-purpose bottle cap, than existing broad mouth type reagent bottle, it has omitted outside support section, simplify the structure, can realize the low-residual of reagent, and can realize when gap between the steady placement of filling front reagent bottle and the inside top surface of the filling rear sealing to reagent bottle, especially bottle cap and the bottom outer wall at the bottle end has guaranteed that bottle cap is installed to bottleneck and can in bottle, not introduce pollutants by bottle cap.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.

The low-residual reagent bottle that the utility model provides, the bottle 2 that comprises a bottle cap 1 and a hollow blow molding, described bottle 2 comprises bottleneck 21, body 22 and the bottle end 23, the vertical section at the described bottle end 23 is taper or class taper, the internal diameter of described bottleneck 21 is less than the internal diameter of body 22, at the bottom of described bottle cap 1 is sleeved on bottle before reagent bottle filling liquid on 23, and turn-knob is arranged on bottleneck 21, as shown in Figure 3, Figure 4 after reagent bottle filling liquid.

The inside of described bottle cap 1 has screw thread 11 and interior envelope lip 12, similarly, the outside of bottleneck 21 is also formed with screw thread 211, when bottle cap 1 is arranged on bottleneck 21, screw thread 11 in bottle cap 1 coordinates with the screw thread 211 outside bottleneck 21, the outer wall of interior envelope lip 12 contacts with the top inner wall of bottleneck 21, as shown in Figure 6.

In the present embodiment, take at the bottom of class conical flask is example, and at the bottom of this bottle, 23 comprise cylindrical section 231 and contraction section 232, and the internal diameter of described cylindrical section 231 is less than the internal diameter of body 22, and described contraction section 232 has the inner fovea part to downward-extension, as shown in Fig. 5, Fig. 6, Fig. 7.At the bottom of bottle cap 1 is arranged on bottle 23 o'clock, between the inside top surface of bottle cap 1 and the bottom outer wall (as the outside bottom surface of inner fovea part in the present embodiment) at the bottle end 23, there is a gap, as shown in Figure 5, guaranteed like this when bottle cap is installed to bottleneck can in bottle, not introduce pollutants.

Before reagent manufacturer filling liquid, at the bottom of bottle cap 1 is arranged on bottle on 23, now bottle cap 1 and the bottle end 23 power of utilizing plastic deformation to produce combines and closely cooperates, but can firmly pull up gently bottle cap 1 again simultaneously, and now bottle cap can steadily be placed bottle integral body.

After reagent manufacturer filling liquid, bottle cap 1 is rotatably mounted on bottleneck 21, utilize screw thread and interior envelope lip to realize and seal and the liquid in bottle is not leaked bottle, the reagent bottle after filling can be inverted, and the bottle cap by bottleneck makes whole steadily placement.

User, when use is filled with the low-residual reagent bottle of liquid, can screw off bottle cap 1, at the bottom of then bottle cap 1 being installed to bottle, on 23, realizes whereby the steady placement of bottle.After getting liquid, can again bottle cap 1 be reinstalled on bottleneck 21 and be sealed.

In the utility model, at the bottom of the conical flask of low-residual reagent bottle or at the bottom of class conical flask, can guarantee low-residual after imbibition, residual quantity is determined by internal diameter size and the angle of taper size of body, can regulate the two size according to actual needs, thereby obtain different residual quantities.

Low-residual reagent bottle of the present utility model have be narrower than body bottleneck, reduce residual taper or class conical flask at the bottom of and hold dual-purpose bottle cap, than existing broad mouth type reagent bottle, it has omitted outside support section, simplify the structure, the low-residual of reagent be can realize, and steady placement and the filling rear sealing to reagent bottle of filling front reagent bottle by bottle cap, can be realized.

By specific embodiment, the utility model is had been described in detail above, this embodiment is only preferred embodiment of the present utility model, and it not limits the utility model.In the situation that not departing from the utility model principle, equivalent replacement and improvement that those skilled in the art makes bottle Bottom Shape and the structure of reagent bottle, the structure of bottle cap etc., in the technology category that all should be considered as protecting at the utility model.
