具有螺旋倾斜柱的合成树脂瓶
Synthetic resin bottle with spirally inclined pillars
US-8113368-B2用于提高横向强度的合成树脂瓶。
专利摘要
提供一种合成树脂瓶，其形状提高了横向刚性和强度，而不增加材料成本来增厚瓶壁。以低成本提供合成树脂瓶，使得瓶可以在载体线、自动售货机和堆叠储存中平稳使用而不变形。瓶能够执行足以用于热灌装的真空吸收功能。多个突出条状形状的柱部分设置在合成树脂瓶的主体上，柱部分相对于瓶的中心轴线以均匀的倾斜角(α)螺旋倾斜并彼此平行设置，使得圆柱形主体壁防止因作用在横向方向上的压力而变形。
Original abstractA synthetic resin bottle is provided with a shape that improves rigidity and strength in a lateral direction, without increasing the cost of material to thicken the bottle wall. The synthetic resin bottle is provided at a low cost in such a way that the bottles can be used smoothly on the carrier line, in vending machines, and in storage in stacks with no deformation. The bottles are capable of performing a vacuum-absorbing function enough to be used in hot filling. Multiple pillar sections in a projected strip-like shape are disposed on the body of a synthetic resin bottle, the pillar sections being inclined spirally at a uniform angle of gradient (α) relative to a central axis of the bottle and disposed in parallel to one another, so that the cylindrical body wall is prevented from being deformed by a pressure force acting in a lateral direction.
