Description
技术领域technical field
本实用新型涉及一种瓶坯，具体涉及一种塑料瓶坯。The utility model relates to a bottle base, in particular to a plastic bottle base.
背景技术Background technique
目前市面上的瓶坯的外形大部分都是颈部大，底部小，坯身呈漏斗形，这样的外形相应的模具结构简单，但这种外形结构的瓶坯，对吹一些要求厚底或者厚壁的瓶子效果不佳。因此，为了避免现有技术中存在的缺点，有必要对现有技术做出改进。At present, most of the preforms on the market have a large neck, a small bottom, and a funnel-shaped body. The mold structure corresponding to this shape is simple, but the preforms with this shape require thick bottom or thick Walled bottles don't work well. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art.
实用新型内容Utility model content
本实用新型的目的在于克服现有技术中的缺点与不足，提供一种能提高吹塑效果的塑料瓶坯。The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art, and provide a plastic bottle blank that can improve the blow molding effect.
本实用新型是通过以下的技术方案实现的：The utility model is achieved through the following technical solutions:
一种塑料瓶坯，包括坯口和坯身，所述坯口的外侧具有外螺纹，所述坯身由坯底及坯壁围合而成，所述坯壁的壁厚由上至下逐渐增大，所述坯身的外径由上至下逐渐增大。A plastic bottle blank, including a blank opening and a blank body, the outside of the blank opening has external threads, the blank body is surrounded by a blank bottom and a blank wall, and the wall thickness of the blank wall gradually increases from top to bottom. increasing, the outer diameter of the body gradually increases from top to bottom.
进一步，所述坯身的最大外径为30mm以上。Further, the maximum outer diameter of the green body is more than 30mm.
进一步，所述坯壁的最大壁厚为5mm以上。Further, the maximum wall thickness of the blank wall is more than 5mm.
进一步，所述坯底厚度小于或等于所述坯壁最大壁厚。Further, the thickness of the blank bottom is less than or equal to the maximum wall thickness of the blank wall.
相对于现有技术，本实用新型通过使坯壁的壁厚由上至下逐渐增大，可以吹塑出厚底的瓶子，吹塑效果好，成品率高。Compared with the prior art, the utility model gradually increases the wall thickness of the blank wall from top to bottom, so that thick-bottomed bottles can be blow-molded, and the blow-molding effect is good and the yield is high.
