Abstract
A reagent bottle cap comprises an outer cap and an inner cap; the inner cap is arranged in the outer cap and is fixedly connected with the outer cap; screw threads are formed on the inner wall of the outer cap; a ring-shaped bulge is fixedly arranged on the inner wall of the outer cap. Since the inner cap is fixedly connected with the outer cap, and screw threads are formed on the inner wall of the outer cap, and the screw threads are matched and connected with a glass bottle filled with reagent. When in operation, the outer cap is screwed out and drives the inner cap to remove from a bottle mouth; fingers have low probability of being corroded and the bottle cap can be opened easily while the bottle cap is opened; and besides, the arrangement of the ring-shaped bulge facilitates the reagent bottle cap to be closely matched with the reagent bottle.
Description
Technical field
The utility model relates to a kind of reagent bottle cap that is used for the chemical reagent glass bottle.
Background technology
The glass bottle bottle cap of traditional splendid attire chemical reagent, comprise that one and bottleneck cooperate inner cap closely, with the enclosing cover that can cover inner cap and bottleneck, inner cap and enclosing cover are the split setting, because it is comparatively tight that inner cap and bottleneck cooperate, be not easy to open, particularly when splendid attire concentrated acid and concentrated base, this shortcoming is more obvious, and finger contact with inner cap to corrode easily and points when opening inner cap.
The utility model content
The technical problems to be solved in the utility model provides a kind of easy unlatching, and opens a kind of reagent bottle cap that the bottle cap process is not easy to corrode finger.
For addressing the above problem, the technical scheme that the utility model adopted is: a kind of reagent bottle cap comprises enclosing cover and inner cap, it is characterized in that: described inner cap is arranged in the enclosing cover and with enclosing cover captives joint.
Below be to further improvement in the technical proposal:
The inwall of described enclosing cover is provided with screw thread.
Be fixed with annular protrusion on the inwall of described enclosing cover.
Adopt technique scheme, because inner cap is captiveed joint with enclosing cover, the inwall of enclosing cover is provided with screw thread, the glass bottle of screw thread and splendid attire reagent is connected, during work, enclosing cover is screwed out, enclosing cover drives inner cap and deviates from from bottleneck, the process that bottle cap is opened is not easy the corrosion finger and opens easily, and being provided with of projection of going in ring makes things convenient for reagent bottle cap to cooperate closely with reagent bottle.
Come the technical solution of the utility model is further described below in conjunction with drawings and Examples:
Description of drawings
Accompanying drawing is the structural representation of reagent bottle cap among the utility model embodiment.
1-enclosing cover, 2-inner cap, 3-annular protrusion, 4-negative thread.
The specific embodiment
Embodiment, as shown in drawings, a kind of reagent bottle cap comprises enclosing cover 1 and inner cap 2, and inner cap 2 is captiveed joint with enclosing cover 1, and described inner cap 2 is fixedly installed on the center of enclosing cover 1, and enclosing cover 2 is provided with negative thread 4, and the inwall of enclosing cover 1 is provided with and is fixed with annular protrusion 3.
During work, enclosing cover 1 is screwed out, enclosing cover 1 drives inner cap 2 to be deviate from from bottleneck, and the process that bottle cap is opened is not easy the corrosion finger and opens easily, and being provided with of annular protrusion makes things convenient for reagent bottle cap to cooperate closely with reagent bottle.
Claims (3)
1, a kind of reagent bottle cap comprises enclosing cover (1) and inner cap (2), it is characterized in that: described inner cap (2) is arranged in the enclosing cover (1) and with enclosing cover (1) captives joint.
