Abstract

The utility model relates to a beverage bottle with a big calibre and multiple screw heads and a bottle cover, particularly a packing plastic bottle for mineral water or outer space water. The inner diameter of a bottle opening is bigger than 28 mm and can reach 35 mm. The screw threads of the outer wall of the bottle opening is provided with a plurality of screw heads of which the number is 3 to 7 generally. The outer diameter phi of an inner plunger of the bottle cover is matched with the inner diameter phi of the bottle opening. Screw threads on the inner wall of the bottle cover is matched with the screw threads on the outer wall of the bottle opening. Tooth pieces on the lower part of the bottle cover are matched with tooth rings on the lower part of the bottle opening. The big calibre of the utility model enables people to directly drink, so the beverage bottle is convenient like a cup; the multiple screw heads, the inner plunger, the tooth pieces and the tooth rings guarantee the strong sealing performance of the beverage bottle.

Description

Heavy caliber multi-screw head beverage Bottle and bottle cap

The bottle cap that the utility model relates to beverage bottle and matches.Particularly relate to mineral water or space water plastic beverage bottle.

The consumption of the beverage bottle that plastics are made, especially mineral water or space water bottle is very big.But the major defect that existing this type of beverage bottle exists has: the one, and bore is too little, and its internal diameter of the bottleneck is in 25 millimeters, and this small-bore bottle is incompatible with people's mouth, directly drinks very effort, the tracheae of also usually can choking by bottle; The 2nd, the oral area outer wall of bottle is generally single spiral shell head thread or does not have the bulge loop of spiral shell head, poor sealing performance.And the bottle cap that such matches exists unreasonable structure equally, as Chinese patent: 912300906, only rely on the block body of lid bottom to block bottleneck, poorly sealed.

The purpose of this utility model is the design heavy caliber, is convenient to people and directly drinks; And the screw thread that a plurality of spiral shell heads are arranged, hermetically-sealed construction failure-free plastic beverage bottle.

Another purpose of the present utility model is that design has multiple-sealed structure, and the suitable bottle cap that cooperates with the large-bore plastics bottle.

The technical scheme of the utility model heavy caliber multi-screw head beverage bottle is: by at the bottom of the bottle, bottle and bottleneck formed, its so-called internal diameter of the bottleneck is greater than 28 millimeters, the outer wall thread of bottleneck has the spiral shell head more than 3 or 3.

Heavy caliber multi-screw head beverage bottle of the present utility model, the internal diameter of its bottleneck is 32～35 millimeters.

Heavy caliber multi-screw head beverage bottle of the present utility model, the spiral shell head of its bottleneck outer wall thread is more than 5.

Heavy caliber multi-screw head beverage bottle of the present utility model, the spiral shell head of its bottleneck outer wall thread is 7.

Below the utility model heavy caliber multi-screw head beverage bottle, the screw thread of its bottleneck ring gear is arranged.

Heavy caliber multi-screw head beverage bottle of the present utility model has the above necking down in 5 roads on its bottle.

The technical scheme of the utility model heavy caliber multi-screw head beverage bottle cap is: have lid, lid connects urceolus and Nei Sai, and external diameter of plug is 32～35 millimeters in it, and this is to match with internal diameter of the bottleneck.The outer tube inner wall screw thread has the spiral shell head more than 5, and this is to match with the bottleneck outer wall thread.

Heavy caliber multi-screw head beverage bottle cap of the present utility model, external diameter of plug is 34～35 millimeters in it, the outer tube inner wall screw thread has 7 spiral shell heads.

Heavy caliber multi-screw head beverage bottle cap of the present utility model, gear piece is arranged at the bottom of its urceolus, and gear piece matches with the ring gear of bottleneck.

The bottle cap that the utility model discloses a kind of heavy caliber multi-screw head plastic beverage bottle and match, its both fit applications, compared with the prior art, the internal diameter with bottleneck is big, directly drinks just as using cup comfortable; Hermetically-sealed construction is reasonable, and performance is strong, and is effective.

Fig. 1 is the utility model heavy caliber multi-screw head beverage bottle front view;

Fig. 2 is the utility model heavy caliber multi-screw head beverage bottle birds-eye view;

Fig. 3 is the utility model bottle cap front view;

Fig. 4 is the utility model bottle cap upward view.

Below in conjunction with Fig. 1-Fig. 4 embodiment of the present utility model is done detailed explanation.

1, bottleneck; 2, screw thread; 3, ring gear; 4, bottle; 5, necking down; 6, the bottle end; 7, lid; 8, cylindrical shell; 9, negative thread; 10, interior plug; 11, gear piece; 12, draw lobe; φ, internal diameter of the bottleneck; In φ ', the bottle cap beyond the Great Wall the footpath.

The utility model relates to the beverage Bottle and bottle cap that plastics are made, and particularly at existing mineral water or space water Packaging Bottle, its bottleneck is too little, directly drinks not smoothly, and promptly people's mouth is big, and bottle is young, uses uncomfortable.Existing in addition bottle hermetically-sealed construction is unreasonable.The technology of the present invention is designed to greater than 28 millimeters the internal diameter φ of circular bottleneck 1, is generally 32～35 millimeters, and the best is 34～35 millimeters, and the external diameter φ ' of plug 10 cooperates with internal diameter of the bottleneck φ in the bottle cap.Bottleneck 1 outer wall is a multi-screw head screw thread 2, is generally 3 or 3 above spiral shell heads, is convenient for the ease of compressing into loam cake, guarantees good airproof performance, and the best is 5～7 spiral shell heads, the corresponding cooperation with it of cylindrical shell 8 negative threads 9 of bottle cap 7.In the bottleneck bottom ring gear 3 is arranged, ring gear can be whole circle ring, also can be interrupted, and as shown in Figure 2, gear piece 11 is arranged under bottle cap, and gear piece 11 matches with ring gear 3.The design of ring gear, gear piece is to consider from sealing and theftproof performance, draws lobe 12 gear piece 11 of ining succession under the bottle cap 7, disconnects after the uncork.That bottle 4 can be designed to is square, circle etc., and multiple tracks necking down 5 is arranged, and plays a part to gain in strength.
