Abstract
A lockable closure for a container having an annular lip advantageously has locking means whereby the closure can be releasably locked to the container. The closure has at least an annular portion adapted to be disposed in contact with a portion of the annular lip of the container, and preferably also an annular wall adapted to contact a portion of a wall of the container to provide a sealing engagement therewith. The locking means generally comprises shoulder means for lockingly engaging the annular lip of the container and bending means adjacent the shoulder means for deflecting the shoulder means about the annular lip of the container. The closure is useful with containers formed of various materials, for example, of both metal and molded plastic.
Claims12
A lockable closure for a container having a wall with a radially displaced downwardly extending annular lip, comprising:
- an annular portion adapted to be disposed in contact with a portion of the annular lip of the container,
- shoulder means adapted to pivot about the extended end of the annular lip of the container, said shoulder means being integral with and extending from said annular portion of said closure, said shoulder means being movable into and out of engagement with the extended end of the annular lip of the container, and
- deflectable bending means integral with and extending from said shoulder means, said deflectable means cooperating with said shoulder means to provide a mechanical leverage system for pivoting said shoulder means about the extended end of the annular lip of the container, said mechanical leverage system being adapted to move said shoulder means into and out of engagement with the extended end of the annular lip of the container,
- said deflectable bending means including an annular continuous portion normally retaining said shoulder means in either an unstressed unlocked position out of engagement with the extended end of the annular lip of the container or a substantially unstressed locked position in engagement with the extended end of the annular lip of the container.
A lockable closure for a container having an annular lip, comprising:
- an annular portion adapted to be disposed in contact with a portion of the annular lip of the container,
- shoulder means for lockingly engaging the annular lip of the container, said shoulder means extending from said annular portion of said closure, and
- deflectable bending means including a plurality of ribs extending from said shoulder means, said deflectable bending means having an annular continuous portion for reversibly deflecting each of said ribs to thereby reversibly deflect said shoulder means adjacent thereto about the annular lip of the container into and out of locking engagement therewith, said annular continuous portion normally retaining said shoulder means in either a locked or an unlocked condition relative to the annular lip of the container.
A lockable closure for a container having an annular lip, comprising a closure having an annular well adapted to be disposed within the area of the container defined by said annular lip, said well having an annular outer wall having at least one portion which is adapted to contact a portion of a wall of the container in sealing engagement therewith;
- said closure having an annular portion adjacent said outer wall adapted to be disposed in contact with a portion of the annular lip of the container when said portion of the outer wall is in contact with a portion of a wall of the container;
- said closure having an annular shoulder extending from said annular portion and an annular deflectable portion being bendable to pivot said shoulder about the annular lip of the container into and out of locking engagement therewith.
