Abstract

The utility model relates to a plastic bottle cover which is matched with the bottle jack of a liquid bottle, which is composed of a cover sleeve and a cover roof. The lower part of the cover sleeve is provided with screws which is matched with the bottle jack, and the lower part is provided with an air inlet. An air inlet pipe is arranged in the air inlet. The upper part of the cover sleeve is provided with a hollow column with two convex clamps. The cavity of the cover roof is matched with the outline of the hollow column on the upper part of the cover sleeve. When assembled, the cover roof is sheathed on the hollow column of the cover sleeve. The cover roof can slide on the hollow column upward and downward. Thus, the opening and the closing of the bottle cover are realized. The plastic bottle cap has the advantages of easy use and simple operation; when pouring liquid, the flow speed and the flow rate can be controlled well, which prevents the liquid forming overflowing to waste.

Description

Plastic bottle cover

The utility model relates to a kind of plastic bottle closure that family, commodity use, particularly with the suitable plastic bottle closure of the bottleneck of holding liquid bottle.

Present family and commercial and be used for holding liquid such as soy sauce, vinegar, rape oil, beverage, the various liquid of hair washing, liquid detergent and Travelling canteen, glass bottle that gal human relations bucket or the like is used and the suitable bottle cap of plastic bottle bottleneck, be broadly divided into: rotary screw cap (or being added with a leak free plastics inner cap), need during use bottle cap is taken off, again bottle cap is screwed on after pouring out liquid, when not only using, this bottle cap bothers, simultaneously, air can intermittently enter in the bottle to regulate air pressure from same bottleneck when pouring liquid, thereby make a bottle internal gas pressure be in the fluctuation shape, the liquid of outflow is intermittently impacts shape astatically, make flow velocity and flow wayward; The plastic bottle that another kind of dress liquid is used, its bottle cap is made up of inner cap and rotary enclosing cover, cover in it and have an aperture more, the enclosing cover of outwarding winding during use, with finger extruding plastic body, by this pressure liquid is flowed out, because pressure is wayward all, normal too quickly the popping out of liquid, excessive of causing caused waste.

The purpose of this utility model is to design a kind of new plastic bottle closure, should be easy and simple to handle when pouring out liquid, can prevent the waste that liquid spill causes by the flow velocity and the flow of user's wish controlling liquid again.

Bottle cap described in the utility model is made up of lid cover (2) and caping (1).Its lid cover bottom has and the suitable screw thread of the bottleneck of holding liquid bottle, on the lid cover face of its underpart an induction opening is arranged, be equipped with air inlet pipe (3) in the hole, regulate a bottle inner and outer air pressure with this, make liquid stream at the uniform velocity, stable, lid cover top is a hollow pillar that two convex clips are arranged, three brace rods are arranged on the cavity wall at hollow pillar top, there is a solid little garden platform on the top of muscle, the gap of muscle communicates with bottleneck, perhaps have in hollow pillar by the fixing solid little garden post of three muscle, and form the hole that a circle communicates with bottleneck with the wall of hollow pillar, the top diameter of its little garden platform or solid little garden post all is greater than the diameter of caping top-portion apertures; The inner chamber of caping is suitable with the outline of lid cover top hollow pillar, on the outline of caping bottom, boss D is arranged, the top of caping has aperture, the diameter of aperture is less than the diameter of the solid little garden platform on lid cover muscle top, hollow pillar top, between the outer wall of caping and inner chamber, have a ring recess E, its purpose is in the elasticity that increases caping, so that assembling, during assembling the caping gland is being covered on the hollow pillar that overlaps, caping can be on covering on the hollow pillar that overlaps, lower slider, the distance of sliding is two distances between convex clip, A point and A ' point when toward lower slider among Fig. 3 and Fig. 4, B point and B ' point, C point and C ' some difference corresponding matching, boss D covers induction opening D ' completely, and as Fig. 1, bottle cap was in and closed shape this moment; C point and B ' some cooperation when up sliding, caping does not break away from the lid cover, as Fig. 2, this moment, bottle cap was in the unlatching shape, and the aperture of the liquid in the bottle through the space of the hollow pillar of lid cover, top braces muscle and caping top flows out or through hollow pillar and the hole that communicates with bottleneck of a circle of the solid little garden intercolumniation in it and the aperture outflow at caping top.

When use plastic bottle closure described in the utility model, only need upper and lower slip caping promptly to realize the switch of bottle cap, easy and simple to handle, practical, when pouring liquid, the inside and outside air pressure of bottle is adjustable, makes liquid flow at the uniform velocity, stablize, and the unlikely liquid spill that causes can cut the waste.

Embodiment

Plastic bottle closure described in the utility model can be made a series of suitable bottle caps according to the bottleneck size of holding liquid bottle, now only gives an example.

When the threaded lower diameter of lid cover is φ 35mm, the diameter of the hollow pillar of band convex clip is respectively φ 11mm and φ 9mm, distance between two convex clips is 6mm, and the height of hollow pillar is 17mm, and the diameter of the hollow little garden platform on hollow pillar upper support muscle top is φ 7mm; The induction opening diameter is φ 4mm, opens at decentering axle 13mm place, and intake manifold length is 20mm; The height of caping is 17mm, and the hole diameter at caping top is φ 4mm, and caping bottom upperlimit is 22mm, the thick 3mm of boss.

During assembling, the caping gland is put at lid, promptly form plastic bottle closure described in the utility model.

Claims
