Abstract

The utility model discloses a bottle mouth which comprises a bottle mouth body and a bottle cover. The utility model is characterized in that corresponding three heads and three sections of equal helical angle threads are respectively arranged on the outer circumference of the bottle mouth body and the circumference of an inner hole of the bottle cover and are in a staggered and uniformly distributed mode. The radian of projections on the cross section of the bottle mouth body and the cross section of the bottle cover are respectively equal. The bottle mouth has the advantages of material saving, convenient opening and strong practicality. A bottle can be opened after the bottle mouth is rotated for 120 DEG. The inner diameter of the bottle mouth body can reach 22mm to 25mm. The height of the bottle mouth body can be shortened to 15mm to 17mm.

Description

Bottleneck

The utility model relates to a kind of bottleneck of bottle, especially the bottleneck that is threaded with the bottleneck body of bottle cap.

The bottleneck of general in the market bottle, its bottle cap mostly is with the bottleneck body and is threaded, and uses very extensive, bottle as various beverages such as pure water, the viscid bottle of various fluids etc., it is comparatively convenient to use, but the bottleneck connecting thread of this class bottle is single thread screw, thereby open slower, need rotation just can open for 720 °, the height of bottleneck body is wanted big naturally and can't be shortened, and feed consumption is also just many naturally, bottleneck body internal diameter can not enlarge simultaneously, can only maintain about 22mm.

The purpose of this utility model provides a kind of bottleneck that can overcome the bottle of above-mentioned shortcoming, and it is very fast, convenient that it is opened, and the bottleneck height can shorten, and bottleneck body internal diameter can increase, material-saving.

For achieving the above object, the solution that the utility model adopts is: a kind of bottleneck, comprise: the bottleneck body and the bottle cap that is bolted on the bottleneck body that are positioned at boss top, it is characterized in that: the excircle of described bottleneck body is provided with three three sections equal helix angle screw threads, and being staggered uniform shape, its projection radian on bottleneck body cross-sectional plane all equates; The described bottle cap that is bolted on the bottleneck body, its endoporus circumference are provided with and corresponding three three sections equal helix angle screw threads of bottleneck body, and this screw thread is staggered to be distributed on the bottle cap inner periphery, and all equates in the projection radian of bottle cap cross-sectional plane.

Owing to adopt such scheme, the endoporus circumference of the excircle of bottleneck body and bottle cap is equipped with corresponding three three sections equal helix angle screw threads, thereby the unlatching of bottleneck is made things convenient for soon, rotation only just can be opened about 120 °, bottleneck body internal diameter can reach 22mm-25mm, height can shorten to 15mm-17mm, and reaches the raw-material purpose of saving.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the open mode structural representation of the utility model bottleneck.

As shown in Figure 1, bottleneck of the present utility model comprises bottleneck body 2 that is positioned at boss 1 top and the bottle cap 4 that is threadedly connected on the bottleneck body 2, the excircle of bottleneck body 2 is provided with three first-class helical angle screw thread 3a, 3b and 3c, screw thread 3a, 3b and 3c are on the staggered excircle that is distributed in bottleneck body 2, and its projection radian on bottleneck body cross-sectional plane is all equated; Described bottle cap 4 is threaded with bottleneck body 2, have on its endoporus circumference with bottleneck body 2 on screw thread 3a, 3b and screw 5a, 5b and 5c such as corresponding three three sections of 3c, this screw thread 5a, 5b and 5c are staggered uniform shape on the inner periphery of bottle cap 4, and all equate in the projection radian of the cross-sectional plane of bottle cap 4.
