<p>This invention relates to a bottle cap structure (1), wherein a swelling shaped circular cap (15) is set at the upper end plane (12) of the said bottle cap, having also two inverted U shaped branch feet (18, 19) extended and formed from the interior plane of the said circular cap, with four spaces formed by the said two inverted U shaped branch feet into which four straight shaped bodies (30) are separately placed. When the said bottle cap is being placed onto the mouth (3) of the bottle, a gap will be formed between the said two branch feet (18, 19) and the aluminium foil paper (2) which is set on the mouth (3) of the bottle. When the circular cap (15) is being pressed down and turned into a circular arc shape, first cause the two branch feet (18, 19) to pierce through the aluminium foil paper (2) by means of the upper end of the convex body, whereby the aluminium foil paper (2) which has been pierced through will be further expanded under the outward expanding of the two branch feet (18, 19) which is caused by the deformity of the circular shaped cap (15). At the same time, under an outward expansion motion conducted by the four straight shaped bodies (30), the hole which has been pierced through will be further expanded, so as to facilitate the smooth pouring out of the liquid contained in the bottle and achieve the object of providing a sanitary drinks.</p> |
