The tube mouth sleeve 10 has elasticity, and the inner diameter of the tube mouth sleeve 10 is slightly smaller that the outside diameter of the inner tube mouth 5. The inner wall of the tube mouth sleeve 10 is provided with a sealing ring 12. The utility model has the advantages of simple structure, reliable performance and low cost. The utility model is widely suitable for packaging bottles with bigger volume.

Description

A kind of improved top-opened anti-theft sealed plastic bottle cap

The utility model relates to a kind of plastic bottle closure, and particularly a kind of top-opened anti-theft sealed plastic bottle cap belongs to plastic container tool field

The top-opened plastic bottle closure of prior art, side such as Granted publication CN2190088Y disclose a kind of top-opened bottle cap that is made of enclosing cover and inner cap, and its constructional feature is that enclosing cover has aperture, and tube wall extends internally into tubulose, and inner cap covers the mouth of pipe.Bottle stands upside down during use, utilizes thimble upwards to back down inner cap, and liquid flows out from thimble in the bottle, has got the drop-down inner cap that makes of liquid back center and has covered the mouth of pipe again.But there is following shortcoming in this technology: 1. inner cap comes off after repeatedly open on the top easily; 2. poor sealing; 3. anti-theft is poor.

The purpose of this utility model provides a kind of improved top-opened anti-theft sealed plastic bottle cap, this top-opened anti-theft sealed plastic bottle cap can overcome prior art shortcoming, prevent that inner cap from coming off, good airproof performance, anti-theft be strong.

The purpose of this utility model can take following measure to reach: a kind of improved top-opened anti-theft sealed plastic bottle cap, comprise enclosing cover and inner cap, enclosing cover has aperture, hole wall extends internally into tubulose, form inner spout, cover outward and be provided with handle, its constructional feature is: the top of the madial wall of enclosing cover, top are provided with clasp, seal ring; Inner cap comprises mouth of pipe plug and mouthpiece cover, and the opening of mouth of pipe plug makes progress, and the inboard of this opening is provided with an internal buckle ring, and the shape of mouth of pipe plug is coincide with the shape of inner spout, external diameter is bigger slightly than the internal diameter of inner spout, and mouthpiece cover is flexible, internal diameter is slightly littler than inner spout external diameter.

Constructional feature of the present utility model also has: inner spout is tapered, and mouth of pipe plug is tapered, and is corresponding with the bullet of inner spout, and mouthpiece cover is provided with a seal ring.

Constructional feature of the present utility model also has: cover the point-like reinforced rib that is provided with ring stiffener, symmetry outward.

Compared with prior art, the utlity model has following outstanding advantage:

Since in be covered with internal buckle ring, therefore though open through top repeatedly, inner cap can not come off, and can effectively prevent the interior liquid refluence of bottle.

2. cover top portion is provided with seal ring, and inner spout is by mouth of pipe plug and mouthpiece cover double-layer seal, so good seal performance.

3. be covered with clasp and reinforced rib outward, before tearing handle, clasp and reinforced rib tightly fasten bottleneck, bottle cap can be removed, so theftproof performance are strong.

Below in conjunction with accompanying drawing the utility model being carried out detail describes:

Fig. 1 is the structure cut-away view of the utility model embodiment 1.

Fig. 2 is that the M of the utility model embodiment 1 is to the local structure cut-away view.

Fig. 3 is an A-A structure cut-away view of the present utility model.

Fig. 1, Fig. 2 and Fig. 3 constitute embodiment 1 of the present utility model, and from Fig. 1 and Fig. 2 as can be known, present embodiment comprises enclosing cover 1 and inner cap 2, and enclosing cover 1 has aperture 3, and hole wall 4 extends internally into tubulose, form inner spout 5, and inner spout 5 is tapered; Enclosing cover 1 is provided with the point-like reinforced rib 14 of handle 6, clasp 7, seal ring 8, ring stiffener 13, symmetry.Inner cap 2 comprises mouth of pipe plug 9 and mouthpiece cover 10, the opening of mouth of pipe plug 9 upwards, the inboard of this opening is provided with that an internal buckle ring 11, its shape coincide with the shape of inner spout 5, external diameter is bigger slightly than the internal diameter of inner spout 5, mouth of pipe plug 9 is tapered; Mouthpiece cover is 10 flexible, internal diameter is slightly littler than inner spout 5 external diameters, and corresponding with the bullet of inner spout 5, mouthpiece cover 10 is provided with seal ring 12.

As can be seen from Figure 1, the utility model enclosing cover inwall is provided with clasp 7, seal ring 8, ring stiffener 13 and point-like reinforced rib 14, when bottle cap covers firm bottleneck, clasp 7 tightly fastens bottleneck, add the effect of ring stiffener 13 and point-like reinforced rib 14, therefore before not tearing handle 6, can not with and cover 1 and unload from bottle; Because inner spout 5 is tapered, and correspondingly, mouthpiece cover 10 is provided with seal ring 12, the external diameter of mouth of pipe plug 9 is bigger slightly than inner spout 5 external diameters, so inner cap 2 closely covers inner spout 5 simultaneously; Because mouth of pipe plug 9 is provided with internal buckle ring 11, during use, the thimble of water outlet machine backs down inner cap 2 from mouth of pipe plug 9, liquid flows out from the opening of thimble in the bottle, and thimble is fastened by internal buckle ring 11 simultaneously, in the use if when bottle mentioned, eedle can retract inner cap and cover firm inner spout, can not cause inner cap to come off.
