具有不可移除且不可旋转的分配盖的分配包装
Dispensing package having non-removable and non-rotatable dispensing closure
US-8308004-B2一种防误开和防旋转的分配盖。
专利摘要
一种分配包装包括容器，该容器具有带轴线的颈部接口、在垂直于轴线的平面中的非圆形横截面，以及颈部接口上的至少一个周向延伸的外部接合元件。盖子具有容纳在容器颈部接口上的壁。该壁具有与颈部接口的非圆形横截面对应的非圆形横截面，以及至少一个与颈部接口上的外部接合元件接合的周向延伸的内部接合元件。内部和/或外部周向延伸的接合元件具有浅引入角，以便将盖子压配到容器颈部接口上，以及陡峭的返回角，以阻止盖子从颈部接口移除。通过颈部接口和盖子壁的非圆形横截面防止盖子相对于颈部接口旋转。
Original abstractA dispensing package includes a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circumferentially extending external engagement element on the neck finish. A closure has a wall received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element in engagement with the external engagement element on the neck finish. The internal and/or external circumferentially extending engagement element has a shallow lead-in angle to enable press-fit of the closure onto the container neck finish and a steep back angle to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall.
