A bottle opener and a method for opening a bottle cap using the bottle opener

Abstract

The invention discloses a bottle opener, which comprises a pressing cover, an upper toothed ring, a retaining ring, a lower toothed ring, a large return spring and a bottom ring. The upper toothed ring is set in the holding ring, and the lower toothed ring is sleeved in In the retaining ring, the retaining ring is arranged between the pressing cover and the bottom ring, and the large return spring is arranged in the bottom ring. The present invention utilizes the rotating structure formed by the upper toothed ring, the retaining ring and the lower toothed ring to twist the bottle cap only by applying a small downward pressure; Labor-saving and convenient to open the bottle cap. The hollow cylindrical ring on the upper part of the bottom ring has a taper that is slightly biased towards the center of the circle, which can ensure that the cylindrical ring deforms inward when the retaining ring is pressed down to generate pressure on the bottle cap. The pressure of the taper also ensures that the bottom ring can adapt Most of the volume is similar to the size of the bottle cap, which expands the scope of use.

Description

Technical field: [0001] The invention relates to a bottle opener, which belongs to the technical field of daily necessities. Background technique: [0002] Existing bottle openers are mainly aimed at beer bottle caps or corks, and there is not a bottle opener specially used for opening can caps. In order to play the role of sealing and preventing falling off, the bottle cap and the lower ring of the bottle cap are partially connected in the mechanized production of cans, but this also leads to the need for greater strength when unscrewing the bottle cap for the first time. This is more difficult for the weak and weak, and when there are oil stains on the hand, or the stripes of the bottle cap are damaged, the difficulty of twisting the bottle cap will be greatly increased due to the reduction of friction. . Contents of the invention [0003] The object of the present invention is to provide a bottle opener, which converts the traditional way of rotating the bottle cap to...
