Abstract

The technical proposal needed to be protected of the utility model discloses a pot easy-to-open cover. A connecting bar is extended from the edge of a bottle cover body. An open ring is arranged at the end tail of the connecting bar. A breaching groove is arranged on the cover body. The breaching groove starts with an intersection point of the connecting bar and the edge of the cover body and goes toward the other intersection point. The breaching point goes to an inner circle along a camber line and extends along the direction of the circle. The radian of the breaching groove is less than 90 degrees. The utility model has the advantages that the manufacturing is simple and the use is convenient and so on.

Description

Easy-open bottle lid

Technical field

The utility model technical scheme required for protection relates to a kind of easy-open bottle lid.

Background technology

Conventional bottle cap on the bottled drink such as beer, carbonated drink needs could open with spanner, and is very inconvenient, therefore, occurred easy-open bottle lid on the market.Existing easy-open bottle lid design roughly is divided into two kinds, a kind of is to rivet draw ring and be equipped with the breakthrough groove on bottle cap, tears the breakthrough groove and opens bottle cap by draw ring during unlatching, and there is the riveted joint poor reliability in this easy-open bottle lid, the manufacturing process complexity, the shortcoming that cost is higher.Another kind of easy-open bottle lid is directly to extend draw ring from bottle cap lid edge and be equipped with two at lid to break through groove, after can turning down, draw ring is close on the lid, tear twice breakthrough groove by draw ring during unlatching and open bottle cap, though production technology has been simplified in this design, but still there is a defective, after tearing the breakthrough groove, the major part of the periphery of bottle cap still wraps on the bottleneck, so occur opening the phenomenon of bottle cap sometimes.

Summary of the invention

The utility model technical scheme required for protection technical matters to be solved provide a kind of manufacturing simple, open easy-open bottle lid easily.

The utility model technical scheme required for protection is such:

Easy-open bottle lid bottle cap lid edge extends a connecting strap, the connecting strap end is a draw ring, the breakthrough groove is arranged on lid one, the breakthrough groove is a starting point with an intersection point at connecting strap and lid edge, setting out to another intersection point place one side earlier carries out the transition to an inboard circumference along camber line and then extends along circumferencial direction, breaks through the shared radian of groove less than 90 °.

The end of breaking through groove has one section radially little cut channel.

The utility model technical scheme required for protection compared with prior art has obvious improvement: in design of the present utility model; the main body that breaks through groove is circumferencial direction and extends; during use; by draw ring tear break through groove after; the position of splitting of the side of bottle cap is bigger; whole side is totally released; the unlatching bottle cap is very easy to; simultaneously; the end of breaking through groove has one section radially little cut channel; make the action direction of draw ring pulling force at last by tangentially the changing into radially of circumference, the pulling force that lid is subjected to is bigger, and it is easier to open.Lid of the present utility model and connecting strap and draw ring be a punch forming during fabrication, need not rivet, and makes simple.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, bottle cap lid 1 edge of easy-open bottle lid extends a connecting strap 2, the connecting strap end is a draw ring 3, breakthrough groove 4 is arranged on lid one, breakthrough groove 4 is a starting point with an intersection point at connecting strap 2 and lid 1 edge, setting out to another intersection point place one side earlier carries out the transition to an inboard circumference along camber line and then extends along circumferencial direction, breaks through the shared radian of groove less than 90 °.The end of breaking through groove 4 has one section radially little cut channel.

Claims

1, a kind of easy-open bottle lid, bottle cap lid (1) edge extends a connecting strap (2), the connecting strap end is a draw ring (3), it is characterized in that: breakthrough groove (4) is arranged on lid one, breakthrough groove (4) is a starting point with an intersection point at connecting strap (2) and lid (1) edge, setting out to another intersection point place one side earlier carries out the transition to an inboard circumference along camber line and then extends along circumferencial direction, breaks through the shared radian of groove less than 90 °.

2, according to claim 1, it is characterized in that: the end of breaking through groove (4) has one section radially little cut channel.
