In the outer regions of engagement pawl 13, form by the plate of cover opener being made to triangle breach the dip plane 15 having a down dip towards opening 3.Dip plane 15 becomes the rough surface identical with the rough surface 5 of previous embodiment 1.The outside at the circumferential both ends of dip plane 15 become do not form described breach and from the front of dip plane 15 and reverse side to face side or the outstanding shoulder 6 of reverse side.Shoulder 6 has the action effect identical with the shoulder of previous embodiment.That is, in the time that a side engagement pawl is engaged with bottle cap surrounding wall portion lower end, the opposing party's a side shoulder contacts with bottle cap end face, and along with the action of uncapping, shoulder enters bottle cap end face, and cover opener is difficult to move to bottle direction, prevents that engagement pawl from contacting with bottleneck.
Shown in Figure 12 (a) is the example that the front of cover opener 12 and reverse side both sides are formed with engagement pawl 13, end difference 14 and dip plane 15.Shown in this Figure 12 (b) is the example that front is formed with engagement pawl 13, end difference 14 and dip plane 15, reverse side and is formed with the engagement pawl 4 of previous embodiment 1.End difference 14, as shown in Figure 12 (a), is preferably formed on the front and reverse side both sides of cover opener 12.
Week of engagement pawl 13 laterally and the week of dip plane 15 inner peripheral surface be laterally formed with jog 7.Jog 7 contacts with bottle cap end face 11a and/or surrounding wall portion 11b in the time uncapping.The jog of the present embodiment can be the structure identical with the jog of previous embodiment 1, serves the same role effect.
Figure 13, Figure 14 represent to use cover opener 12 to carry out uncapping of direct action ends-opening method, are the engagement pawl of the rear end side of cover opener 12 13 to be inserted to bottle cap surrounding wall portion 11b lower end contact the state as fulcrum as point of action, the reverse side dip plane 15 that makes front or engagement pawl 4 with bottle cap end face 11a.Now, due to end in contact under the end difference 14 of rear end side and bottle cap surrounding wall portion 11b, therefore, prevent that in the action of uncapping afterwards, cover opener 12 moves to bottle direction.In addition, the shoulder 6 of front contacts with bottle cap end face.When entering when action of uncapping, because bottle cap 11 produces distortion, therefore, the dip plane 15 of front or the rough surface of engagement pawl 4 are powerful to be contacted with bottle cap end face 11a, can utilize this friction drag to prevent that cover opener 12 from moving to bottle direction.And then the jog in both sides 7 of the engagement pawl 13 of front enters bottle cap end face or surrounding wall portion, produce larger friction drag, can prevent that cover opener 12 from moving to bottle direction.
Even in negative actuation ends-opening method, just substitute front and rear end side, the occasion generation effect in the same manner of engagement pawl, end difference, dip plane, shoulder and jog and direct action ends-opening method, prevents that cover opener 12 from moving to bottle direction.
In the present embodiment, the shape of opening, size also can be identical with previous embodiment 1.
Preferably, the length L of engagement pawl 13
2be 14～16mm, maximum width (depth) is 1.2～1.5mm, and the thickness t of leading section is 0.9～1.3mm.In addition, the cross sectional shape of engagement pawl also can make echelon form.
In the present embodiment, the state of thickness, angle of inclination and the rough surface of the radius of curvature of the suitable length of dip plane 15, width (depth), front end, leading section is as the criterion with the engagement pawl 4 of previous embodiment 1.
