Abstract
The utility model discloses a sealing structure for a blow molding container mouth. The technical problem to be solved is that an outlet of a blow molding container is not deformed after the whole blow molding container is blown and molded to form, therefore the sealing connection with a cover can be ensured. A metal ring with an inner screw is inlaid in the blow molding container mouth, and is matched and connected with a metal cover by a sealing screw. The utility model is suitable for the application of all blow molding containers, such as a blow molding tank, a blow molding can, etc.
Description
Technical field
The utility model relates to the hermetically-sealed construction of plastic container technical field, particularly a kind of blow molded container mouth.
Background technology
Existing blow-molded container as blowing bucket, blowing jar etc., all is provided with one or more outlet, and these plastics export direct blowing and go out negative thread, are threaded with being with externally threaded vinyl cover.In general, deform easily because of reasons such as contractions after the demoulding of blow-molded container global formation for small-bore plastics outlet, the vinyl cover outside thread that causes matching originally can't be screwed into, or be screwed into the sealing effectiveness that has also destroyed it reluctantly, cause leakage in the transporting procedures, safety in production is brought harm, also cause raw-material waste.
Summary of the invention
The technical problems to be solved in the utility model is that the blow-molded container outlet after Unitarily blowing formed is indeformable, thereby guarantees can be tightly connected with lid.
The technical solution that the utility model proposed is such: a kind of hermetically-sealed construction of blow molded container mouth, comprise mouth of blow molded container 1, in described mouth of blow molded container 1, be inlaid with tapped wire loop 2, be connected with being with externally threaded crown cap 3 coupling sealing threads.Be provided with the excurvation conical surface on wire loop 2 tops, be provided with excurvation ring limit, right angle, between the excurvation conical surface and inboard, excurvation ring limit, right angle, be embedded with O-ring seal 4, make between wire loop and the crown cap and form double sealing structure at crown cap 3 upper tops.
Compared with prior art, the utlity model has following beneficial effect:
Owing in the integral blow process, tapped wire loop is embedded in the mouth of blow molded container, be connected with the crown cap thread seal again during use, thereby, guarantee indeformable, the good airproof performance of mouth of blow molded container, and the open and close lid is smooth and easy.
The utility model is suitable for all blow-molded containers, as application such as blowing bucket, blowing jars.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, blow-molded container and mouth 1 thereof are blow molded into container with tapped wire loop 2, these wire loop 2 tops are provided with the excurvation conical surface, and crown cap 3 upper tops are provided with excurvation ring limit, right angle, crown cap 3 is connected with wire loop 2 thread seals.Between the excurvation conical surface of inboard, excurvation ring limit, the right angle of above-mentioned crown cap 3 and wire loop, rubber seal 4 is housed, reaches the purpose of mouth of blow molded container double seal, guaranteed the safety of accumulating.
Claims (2)
1, a kind of hermetically-sealed construction of blow molded container mouth comprises mouth of blow molded container (1), it is characterized in that: be inlaid with tapped wire loop (2) in described mouth of blow molded container (1), be connected with being with externally threaded crown cap (3) coupling sealing thread.
2, the hermetically-sealed construction of blow molded container mouth according to claim 1, it is characterized in that: described wire loop (2) top is provided with the excurvation conical surface, described crown cap (3) upper top is provided with excurvation ring limit, right angle, is embedded with O-ring seal (4) between the described excurvation conical surface and inboard, excurvation ring limit, described right angle.
