Abstract

The utility model relates to a liquid bottle cover which can be repeatedly opened and closed. The liquid bottle cover is composed of a cover seat and a sealing cover, wherein the lower part of the cover seat is connected with the bottle mouth, the upper part is smaller, and the center of the top end is provided with a liquid outlet which is smaller than the bottle mouth. The sealing cover can be tightly sheathed on the cover seat to cover the upper part of the cover seat, and the liquid outlet which is arranged at the top end of the cover seat can be simultaneously sealed by a cylindrical bulge of the top part. The liquid bottle cover has the advantages of simple and beautiful structure, convenient operation, etc., the liquid amount is controllable, and the utility model can be used on a beverage bottle to be easy to directly drink.

Description

A kind of liquid bottles bottle cap

The utility model relates to a kind of liquid bottles bottle cap that can open and close repeatedly.Particularly a kind of have a liquid bottles bottle cap that slows down the liquid outlet quantity effect.

Said liquid outlet quantity is meant that liquid is from the flow of bottleneck or the outflow of bottle cap liquid outlet in the bottle in the present patent application.

The existing liquid bottles bottle cap that can open and close repeatedly generally all is directly to be placed in only to play sealing process on the bottleneck, opens bottle cap during use, and liquid is directly poured out from bottleneck in the bottle.Because general bottleneck is all relatively large, liquid outlet quantity is big and wayward, thus must be very careful when pouring out liquid, the not so liquid measure of very difficult precise control, and spill out easily, it is very inconvenient to operate.Especially bottled drink, often be to open bottle cap promptly directly to drink, without suction pipe the time, must directly drink facing to bottleneck with mouth with bottle, in this case, because bottleneck is relatively large, not only drink uncomfortable, and because of liquid outlet quantity wayward, just can be choked slightly because of carelessness, beverage also is easy to leak from mouth and spills simultaneously, clothes is got wet made dirty, and is very inconvenient.

The purpose of this utility model provides a kind of liquid bottles bottle cap that can open and close repeatedly, and it not only opens and closes conveniently, and sealing is reliable, and can slow down liquid outlet quantity, liquid outlet quantity is controlled easily, handled easily, be used for then can making things convenient for directly on the beverage bottle and drink, thereby remedy the existing existing deficiency of bottle cap.

Bottle cap of the present utility model is made of cage and seal cover cap.The cage bottom is bigger, and top is less; Its underpart intracavity diameter size matches with bottleneck, and the negative thread that cooperates connection with bottleneck is arranged; There is a circular liquid outlet in cage upper end central authorities, and this liquid outlet diameter is less than internal diameter of the bottleneck; The outer middle side part of cage has the annular arrangement step of a diameter between top and the bottom.Seal cover cap is an inverted cylindrical or truncated cone-shaped cup-shaped, and its lower end size combines with the annular arrangement step of the outer middle side part of cage, and has the structure that can be locked mutually; There is a cylindrical protrusions in the inside, seal cover cap top central authorities, and this protruding diameter becomes micro-interference fit with the liquid outlet of cage upper end; When the height of seal cover cap should be able to make its lower end be locked on the annular arrangement step of outside cage middle side part, the cylindrical protrusions at its top just compressed or fills in the liquid outlet on cage top, with its sealing

When bottle cap of the present utility model used, cage was tightened and is fixed on the bottleneck, only need open or cover seal cover cap, can realize opening and closing of fault, and needn't touch cage top, so open and close very convenient with hand, and can avoid cage top especially liquid outlet be subjected to the pollution of staff, guarantee health.This bottle cap employing has certain elastomeric plastic material makes, and has reliable sealing performance.In addition, because the liquid outlet on this bottle cap cage is more much smaller than bottleneck,, make liquid outlet quantity be easy to control, handled easily so can play the effect that slows down liquid outlet quantity; Simultaneously, form a mouth, be more suitable for when being loaded on beverage bottle in directly drinking because cage top is less, and because of liquid outlet quantity retarded, so choked can effectively avoid drinking the time and beverage leaks the situation generation of spilling.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the specific embodiment of the present utility model;

Fig. 2 be the seal cover cap lower end with the annular arrangement step of cage between the structural representation that connects mutually with screw thread.

With reference to accompanying drawing, this bottle cap comprises cage 1 and seal cover cap 2 two parts.Cage 1 bottom has the negative thread 11 that can be locked on the bottleneck, on this top, bottom inner end surface an annular protrusion 15 is arranged, the diameter of this annular protrusion matches with bottleneck upper end (top), when cage is tightened on the bottleneck by negative thread 11, this annular protrusion 15 just props up the bottleneck top, with its sealing; Can certainly replace this annular protrusion 15 with general tightening seal washer.The cage upper diameter can be placed in the seal cover cap it less than the bottom, also makes cage top form a less mouth shape portion simultaneously, when it is used on the beverage bottle, can be more convenient for directly drinking.There is a circular liquid outlet 12 in cage upper end central authorities, and this liquid outlet diameter generally is about 1/4～1/2 of internal diameter of the bottleneck, is generally about 5～10mm.There is an annular arrangement step 13 in the cage outside between top and the bottom, this annular arrangement step outside has an annular groove 14a, inboard, seal cover cap 2 lower end that the one annular protrusion 23a that matches with this annular groove 14a is arranged; Promptly be locked mutually between the annular arrangement step 13 of seal cover cap lower end and cage by this annular protrusion and annular groove; Can reach like this to be tightly linked and to be convenient to and open; Certainly, also can be that the seal cover cap lower end is inboard be annular groove, and annular arrangement step 13 outsides of cage are annular protrusion.Also can be locked mutually between the annular arrangement step 13 of seal cover cap 2 lower ends and cage by screw thread; As shown in Figure 2, annular arrangement step 13 outsides inboard and cage 1, seal cover cap 2 lower ends have screw thread 23b and the 14b that works in coordination respectively, and are locked mutually.There is a cylindrical protrusions 21 in seal cover cap top the inside central authorities, 12 one-tenth micro-interference fit of liquid outlet on its diameter and cage top; This convex center can add a cavity 22, can increase its peripheral elasticity like this, improves its sealing property.The height of seal cover cap 2 should satisfy following condition: when the seal cover cap lower end was locked on the annular arrangement step 13 at cage, the cylindrical protrusions 21 at its top just compressed or fills in the liquid outlet 12 on cage top, and with its sealing.

The outside, cage bottom of this bottle cap can have the annular knurl decorative pattern, also the cage lower, outer perimeter can be made equilateral polygon, makes it both be convenient to turn, and increases attractive in appearance again.

The utility model bottle cap has characteristics such as simple and beautiful structure, performance are good, easy to use, on the various liquid bottles that open and close repeatedly applicable to needs, is specially adapted to as the liquid beverage bottle of directly drinking.
