Abstract

The utility model provides a bucket cover of blow molding plastic buckets, which is characterized in that the bucket cover of blow molding plastic buckets comprises a transition bucket mouth connected with a plastic bucket mouth by a screw thread, a cover body which is made by injection molding and has certain elasticity, and an outer periphery, wherein an outer edge of the cover body is buckled in the transition bucket mouth from the top part and is in interference fit with the transition bucket mouth; the top part of the outer periphery which tightly and annularly surrounds the transition bucket mouth is made into a whole with the bottom surface of the outer edge by injection molding to form an annular space with the cover body; a certain gap exists between the top end in the annular space and the top part of the transition bucket mouth; a wrench button is arranged on the cover body by injection molding; the injection molding surface of the wrench button and the cover body has a trapezoid and corresponds to the upper bottom of the trapezoid injection molding surface; grooves are arranged on the upper part and the outer edge of the outer periphery of the annular space; the bucket cover is installed on the plastic bucket mouth by the screw thread. When liquid is poured, the wrench button is wrenched towards the direction of the lower bottom of the trapezoid injection molding surface; the cover body deforms and disengages from the transition bucket mouth on the grooves to form an outlet with the transition bucket mouth for the liquid to flow out of the outlet. The wrench button is released, all articles recover and the liquid is sealed in a bucket.

Description

The bung of blow molding Plastic Drum

Affiliated technical field

The utility model provides a kind of bung of blow molding Plastic Drum, belongs to the seal of vessel technical field.

Background technology

Various on the market plastic container, common have buckets 25 kilograms, 10 kilograms or the like.Fairly simple with the matched cap structure of these Plastic Drums, be simple sealing function, if want to pour out liquid from these containers, by other water conservancy diversion device, liquid more or less all can not trickled down on the ground.Its shortcoming is, seals not tightly, and liquid taking is relatively harder, trouble, particularly 25 kilograms bulk container.

The utility model content

The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, can easily be from plastic container do not take out liquid by any guiding device and can not trickle down the bung of the blow molding Plastic Drum outside the target container.Its technology contents is:

A kind of bung of blow molding Plastic Drum, it is characterized in that: comprise a transition bucket nose that is threaded with the plastics bucket nose, injection mo(u)lding and certain elastomeric lid and outer peripheral edges are arranged, wherein lid band outer be fastened on from the top in the transition bucket nose and with transition bucket nose interference fit, closely be looped around transition bucket nose outer peripheral edges all around, the bottom surface of its top and outer is injection molded into one, constitute an annulus with lid, the inner tip of annulus has certain clearance apart from the top of transition bucket nose, injection moulding one switch knob on the lid, the injection-molding surfaces of switch knob and lid is trapezoidal, corresponding to the upper base of trapezoidal injection-molding surfaces, annulus has groove at the top and the place, outer of outer peripheral edges.

The bung of described blow molding Plastic Drum, outer peripheral edges and transition bucket nose interference fit; Perhaps outer peripheral edges are connected with transition bucket nose screw.

The bung of described blow molding Plastic Drum, the sidewall of lid is curved, and its internal diameter is gradually little, is injection molded into one with the outer and is peviform.

The bung of described blow molding Plastic Drum is set up a handled cover of dust and is fastened on the transition bung.

The bung of described blow molding Plastic Drum, transition bucket nose and plastics bucket nose threaded connection place are provided with O-ring seal.

When needs are poured out liquid, only need to pull switch knob toward the direction of going to the bottom of trapezoidal injection-molding surfaces, lid will be out of shape at groove disengaging transition bucket nose, and then forms an outlet with the transition bucket nose, and liquid just therefrom flows out.Unclamp switch knob, all recoveries, liquid is sealed in the staving by lid, so repeatedly.It compared with prior art need not just can easily take out liquid and can not trickle down outside the target container from plastic container by any guiding device, is specially adapted to the Drinking water bucketr of 25 kilograms of present dresses, conveniently takes.Rational in infrastructure, easy to use, excellent working performance.

Description of drawings

Fig. 1 is the structural representation that the utility model embodiment is in sealing state;

Fig. 2 is an A-A section-drawing embodiment illustrated in fig. 1;

Fig. 3 is the A-A section-drawing behind the fastening cover of dust embodiment illustrated in fig. 1;

Fig. 4 is the structural representation that the utility model embodiment is in down liquid state.

The specific embodiment

1, bucket nose 2, transition bucket nose 3, lid 4, outer 5, outer peripheral edges 6, annulus 7, switch knob 8, projection 9, groove 10, outlet 11, cover of dust 12, handle 13, O-ring seal

Transition bucket nose 2 is threaded with the bucket nose 1 of Plastic Drum, with outer 4 injection moulding all-in-one-piece elasticity lids 3, its sidewall is curved, internal diameter is gradually little, be peviform, be fastened on from the top in the transition bucket nose 2 and with transition bucket nose 2 interference fit, be looped around closely that outer peripheral edges 5 around the transition bucket nose are sleeved on the transition bucket nose 2 and with its interference fit, the bottom surface of its top and outer 4 is injection molded into one, constitute an annulus 5 with lid 3, the inner tip of annulus 5 has certain clearance apart from the top of transition bucket nose 2, injection moulding one switch knob 7 on the lid 3, switch knob 7 is trapezoidal with the injection-molding surfaces of lid 3, and corresponding to the upper base of trapezoidal injection-molding surfaces, annulus 6 has groove 9 at the top and 4 places, outer of outer peripheral edges 5.When needs are poured out liquid, only need to pull switch knob 7 toward the direction of going to the bottom of trapezoidal injection-molding surfaces, lid 3 will be out of shape at groove 9 places disengaging transition bucket nose 2 thereupon, and then forms an outlet 10 with transition bucket nose 2, and liquid just therefrom flows out.Unclamp switch knob 7, all recoveries, liquid just is sealed in the bucket, so repeatedly.

For keeping health, the cover of dust 11 of setting up a band handle 12 is fastened on the bung.
