Abstract
The utility model relates to a volumetric flask. The volumetric flask comprises a pear-shaped glass volumetric flask bottle body (1) with a fine neck and a flat bottom, and a plastic bottle plug (2), wherein the inner wall at the position of a bottle opening (11) of the volumetric flask bottle body (1), which is used for mounting the plastic bottle plug (2), is in a straight-barrel shape; the lower haft section of the plastic bottle plug (2) is inserted into the straight-barrel-shaped bottle opening (11) of the volumetric flask bottle body (1); and a plurality of paths of annular soft and dense sealing fins (21) are arranged on the outer wall of a sealing and matching position of the plastic bottle plug (2) and the bottle opening (11) in a peripheral direction. The volumetric flask disclosed by the utility model has the advantages of good sealing performance, easiness of fastening down the bottle plug and easiness of being opened after the cover is fastened down. The opening and the sealing of the bottle plug are convenient so that the bottle plug is more convenient to use. The bottle plug is not easy to lose when the bottle body is transversely stored and placed and is not easily stuck with the bottle body.
Description
Technical field
The utility model relates to the chemical test container, is specifically related to a kind of volumetric flask.
Background technology
Volumetric flask is the container a kind of commonly used in the chemical test, is used for the accurately solution of preparation certain volume concentration, and general bottleneck is furnished with ground glass stopper.The volumetric flask closure of ground glass stopper is better, but is in the same place with bottle is glutinous easily with ground place after crossing, and is not easy to open.Glass stopper came off easily and causes losing when bottle was laterally stored placement.Though can be tied together bottle stopper and bottle with rubber case, rubber case is aging easily, and effect is undesirable, often causes bottle stopper and bottle not to match and causes phenomenon of leakage generation, needs further improvement.
Summary of the invention
The volumetric flask that the purpose of this utility model provides that a kind of closure is good, bottle stopper covers tightly easily, open easily after covering tightly.
Technical solution of the present utility model is: it comprises thin neck, pyriform, flat glass volumetric flask bottle and Plastic bottle plug, the inwall that the volumetric flask bottle is installed the position of bottleneck of Plastic bottle plug is straight tubular, the lower semisection of Plastic bottle plug is inserted in the straight tubular bottleneck of volumetric flask bottle, and Plastic bottle plug and bottleneck are sealed and matched mutually and circumferentially are provided with some roads annular soft seal wings on the outer wall of position.
Technique effect of the present utility model is: it is good that it has closure, and bottle stopper covers tightly easily, the advantage of opening easily after covering tightly.It is convenient that its bottle stopper is opened and sealed, and is more convenient for using.Bottle stopper is laterally stored when placing at bottle and is difficult for losing, and also is difficult for being in the same place with bottle is glutinous.
Description of drawings
Fig. 1 cuts open schematic diagram for the utility model embodiment bottleneck office.
The specific embodiment
As shown in drawings, it comprises thin neck, pyriform, flat glass volumetric flask bottle 1 and Plastic bottle plug 2, the inwall that volumetric flask bottle 1 is installed bottleneck 11 positions of Plastic bottle plug 2 is straight tubular, the lower semisection of Plastic bottle plug 2 is inserted in the straight tubular bottleneck 11 of volumetric flask bottle 1, and Plastic bottle plug 2 and bottleneck 11 are sealed and matched mutually and circumferentially are provided with some roads annular soft seal wings 21 on the outer wall of position.
The position that Plastic bottle plug 2 is positioned at bottleneck 11 is provided with the annular seal groove 22 under shed that is enclosed within bottleneck 11 annular outer rib peripheries when Plastic bottle plug 2 covers from the top down.The top of Plastic bottle plug 2 is provided with spherical button 23.Plastic bottle plug 2 is the goblet that falls under shed.
