The object of the invention is to provide a bottle cap and a drinking bottle applying the cap to improve the sealing of the drinking bottle. The bottle cap of the invention comprises a top wall and a side wall arranged around the top wall and extending downward. The key is that a concave part is arranged in the middle of the top wall, and the outer side of the concave part has a circular annular gap between the side wall and the top wall. The drinking bottle comprises a bottle body and the cap. The side wall of the bottle cap is wrapped at the bottle mouth of the bottle body, the side wall of the bottle cap is pressed at the outer wall of the bottle mouth, the side wall of the concave part is pressed at the inner wall of the bottle mouth, and the outer edge of the top wall is pressed at the top surface of the bottle mouth. Unlike the traditional bottle cap, which only relies on the side wall of the bottle cap and the sealing of the bottle mouth, the top of the bottle cap in the present invention has a concave part in the center, so that the sealing surface in three directions can be formed between the bottom of the top wall of the bottle cap and the top of the bottle mouth, between the side wall of the concave part and the inner wall of the bottle mouth, and between the side wall of the bottle cap and the outer wall of the bottle
【技术实现步骤摘要】
一种瓶盖及应用该瓶盖的饮用瓶
本专利技术属于饮料包装
,具体涉及到一种瓶盖及应用该瓶盖的饮用瓶。
技术介绍
许多饮用瓶都是利用金属瓶盖来密封瓶体的,传统的金属瓶盖都是利用其边缘压紧瓶口的四周来实现与瓶体的连接及密封的,上述瓶盖的密封面积较少,且密封方向单一,因此密封效果较差。有些饮料需要在较高压力下才能保持良好的口感,这就需要瓶盖的密封性非常好,因此有必要对瓶盖的结构进行改进,以提高其对瓶体的密封性。
技术实现思路
本专利技术的目的是提出一种瓶盖及应用该瓶盖的饮用瓶,以提高饮用瓶的密封性。本专利技术的瓶盖包括顶壁及设于顶壁四周并向下延伸的侧壁,关键在于所述顶壁的中部设有凹部,所述凹部的外侧与所述侧壁之间具有圆形环状间隙。本专利技术的饮用瓶包括瓶体及上述的瓶盖,所述瓶盖的侧壁包裹于瓶体的瓶口处,瓶盖的侧壁压紧于瓶口的外壁处,凹部的侧壁压紧于瓶口的内壁处,顶壁的外缘压紧于瓶口的顶面处。与传统瓶盖只依靠瓶盖侧壁与瓶口密封不同,本专利技术中的瓶盖顶部中央设置了凹部,这样瓶盖顶壁的底面与瓶口的顶部之间、凹部的侧壁与瓶口的内壁之间以及瓶盖的侧壁与瓶口的外壁之间形成了三个方向的密封面,可以大大提高密封效果。进一步地,所述侧壁的下部设有螺纹,所述瓶口的外壁设有螺纹,所述瓶盖的侧壁下部通过螺纹与瓶口外壁连接,瓶盖还通过螺纹配合与瓶口处连接,不仅提高了密封性,还方便开启瓶盖。进一步地,所述侧壁的底端通过连接桥连接有防盗环,以使瓶盖具有防盗性。进一步地,所述侧壁的上部设有防滑纹,可以在开启瓶盖时增加瓶盖与手之间的摩擦力。进一步地,所述顶壁的底面设有密封垫,瓶盖的顶壁与瓶口的顶 ...
