A Biomimetic Approach to the Design of the Composite Bottle Cap and Deformation Analyses
On the combination analog of the mussel ripple and leaf embrace, designed a new composite bottle cap consisting of the outer body, the inner lining washer, and the resin embrace, for multi-function, especially for better seal and ready open. According to the structural feature and the functional requirements of the cap, two fundamental components, the lining washer and the outer body, were abstracted into a plate and a cylinder with thin wall, respectively. Under the pressing force the elastic and plastic deformations of both were studied with Tresca’s yielding rule and the limitation of the plastic deformation was presented when the two components were assembled into a unit. For the production of this kind of bottle cap, the maximum value of the allowance press and the maximum pressing velocity were also provided.
