Plastic fluid container mouth hermetically-sealed construction

Technical field

The utility model relates to a kind of sealing structure for vessel port, particularly the plastic fluid container mouth hermetically-sealed construction such as a kind of oil drum, oil bottle, oil can.

Background technology

As shown in figure 10, current oil drum, oil bottle, the liquid entrance of the plastic fluid containers such as oil can, its structure comprises that container chews 1 and chew and cover 2, container chews 1 for cylindrical tubular, its lower end and container body 3 are connected as a single entity, its outside is provided with outside thread, it on it, is opening, chew and cover 2 and comprise decorative cover and lid top panel, decorative cover is to chew 1 cylindrical tubular adapting with container, lid top panel is positioned at the top of decorative cover and connects as one with decorative cover, in decorative cover, be provided with container and chew the negative thread that the outside thread in 1 outside matches, chew and cover 2 and be arranged on container by the negative thread on it and chew on 1, container is chewed 1 upper edge and is pressed against and chews in the lid top panel of covering 2, reach the object of sealing, sometimes can also chew 1 upper edge and chew at container and between the lid top panel of covering 2, be provided with a seal ring, to strengthen sealing effectiveness, although the hermetically-sealed construction of this liquid container mouth also can reach certain sealing effectiveness, but it exists between following deficiency: because sealing surface is positioned at the edge that container is chewed 1 opening part top and chewed the lid top panel of covering 2, be that sealing surface is positioned at container and chews 1 opening edge edge, container is chewed mouth does not have cross-tie, so structural capacity is bad, adding is plastics, intensity is lower, so be easy to distortion, and it is little to bear pressure, easily cause leak of liquid, the liquid substance that loss fills at least, heavy can cause the story of ambient contamination (particularly when splendid attire chemical product, once leak, harmful to people's health, serious environment pollution), even cause the grave accident (for example splendid attire oils) of fire.

What have also adds an inner cap in vessel port, due to inner cap and enclosing cover separate, can not enhanced leaktightness intensity, and the sealing surface top of still chewing at container, can't multi-band carry out better sealing effectiveness.

Summary of the invention

The purpose of this utility model is overcome the above-mentioned deficiency of prior art and provide a kind of plastic fluid container mouth hermetically-sealed construction, its (without joining inner cap) simple in structure again; Sealing surface is not positioned at container to be chewed and chews and cover edge, and hermetically-sealed construction intensity is good, not yielding, and good sealing effect can Leakage prevention, the accident such as pollution, fire.

The technical solution of the utility model is: a kind of plastic fluid container mouth hermetically-sealed construction, it comprises that container chews and chew lid, its lower end and container body are connected as a single entity, and are opening on it, and container is chewed the interior annular step ladder type that is provided with an inside extension near its inner side, lower end and chewed sealing surface; Chew lid comprise cover outer ring, lid inner ring and cover base plate, lid inner ring is positioned at and covers outer ring, its top is connected with outer ring by annular roof plate, lid outer ring and lid form between inner ring one and container chew the annular adapting and chew groove, container is chewed to extend into and is chewed the chewing in groove of lid, and the bottom of lid inner ring is provided with one and chews interior annular step ladder type with container and chew the annular step ladder type lid sealing surface that sealing surface matches; Lid inner ring bottom is connected with lid base plate; Chewing lid is arranged on container and chews.

The further technical scheme of the utility model is: the outside that described container is chewed is provided with outside thread; The inner side of lid outer ring is provided with the negative thread that the outside thread in the outside of chewing with container matches, and chews outside thread that lid chews with container by the negative thread on it and matches and be arranged on container and chew.

The utility model further technical scheme is: described container is chewed neck outside and is also provided with an annular groove, and it is corresponding that the annular step ladder type that groove is chewed with container is chewed sealing surface.

The utility model further technical scheme is: what described container was chewed chew sealing surface and chew between the lid sealing surface of lid and be also provided with seal ring.

The utility model also further technical scheme be: what described container was chewed chew sealing surface chews axis formation angle R, 60 °≤R≤120 ° with container.

The further technical scheme of the utility model is: what described container was chewed chew, and axis that sealing surface chews with container is vertical.

The utility model compared with prior art has following features:

1. it is simple in structure, without joining inner cap again;

2. sealing surface is not positioned at container and chews and chew and cover edge, and sealing surface is not the opening edge edge of chewing or chewing lid at container, and the sealing surface that container is chewed is positioned at its lower end, far apart from Qi Kou edge, and chewing lid is the equal of to be folded in, and sealing surface is positioned in the middle of it; Hermetically-sealed construction power is stronger like this, is not easy to deform, and sealing intensity is high, and sealing effectiveness is better;

3. lid base plate plays the effect of sealing on the one hand, on the other hand booster action is played in the bottom of lid inner ring, due to the close bottom of covering inner ring of lid sealing surface of lid inner ring, near lid base plate, lid base plate plays and reinforces the effect of strengthening whole lid inner ring bottom like this, also makes the lid sealing surface that covers inner ring obtain reinforcing reinforcement, and the lid sealing surface intensity of covering inner ring is better, under same material, same thickness, compared with prior art the sealing effectiveness of this structure is better;

4. chew sealing surface and axis and form slanted angle, can form wedge shape effect, be conducive to increase the pressure of sealing surface, enhanced leaktightness effect.

Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
