Screw-type container-closure systems with magnetic feature

摘要

A screw-type closure system comprising a container and closure. The closure comprises a screw-threaded inner cap, a customized wand that depends from the inner cap and supports an applicator surface, an overcap that is enabled to translate axially relative to the inner cap, and one or more magnetic elements. The container comprises a specialized shoulder, a neck having a specialized screw thread profile, a customized wiper that engages the customized wand, an overshell that houses one or more magnetic elements that tend to attract the one or more magnetic elements of the closure.;The closure is screwed onto the container until the inner cap comes to a hard stop, at which point the magnetic elements of the closure are aligned with the magnetic elements of the container. At that point, the overcap (15) of the closure (11) is drawn toward the overshell (4) of the container until they make contact, so that there is no unsightly gap. Also, the contact produces a satisfying, reassuring metallic “click” sound, accompanied by a luxurious tactile sensation.

主权项

1. A screw-type container and closure system that has:
a container (10) that comprises a first subassembly:
the first subassembly comprises:
a reservoir (1) that is able to be filled with a product, and that has a threaded neck (1g) with screw threads (1h);a container overshell (4) having a closed bottom (4b) and an opened top (4a) into which is disposed the reservoir; andone or more first magnetic elements (9) disposed near the top of the container overshell (4); a closure (11) that comprises second and third subassemblies:
the second subassembly comprises:
an overcap (15) having an opened, distal end (15b), and a closed, proximal end (15c);one or more second magnetic elements (19) located near the opened, distal end (15b) of the overcap (15);the third subassembly comprises:
a screw-threaded inner cap (12) that is housed within the overcap (15), and that has a top surface (12e) and a bottom edge (12f);a wand (13) that depends from an inner surface of the inner cap (12); andan applicator surface (14) that is supported at the end of the wand; wherein:
the screw-threaded inner cap (12) and the overcap (15) are stationary with respect to each other in rotation, but the inner cap is able to slide up and down within the overcap (15), between a lower position and an upper position;a spring (20) disposed between the inner cap (12) and the overcap (15), so as to urge the inner cap downward relative to the overcap; andwhen the screw-threaded inner cap (12) is fully rotated onto the threaded neck (1g), a magnetic attraction between the one or more first magnetic elements (9) disposed near the top of the container overshell (4) and the one or more second magnetic elements (19) located near the opened, distal end (15b) of the overcap (15) is sufficient to overcome the bias of the spring (20), and urge the overcap (15) downward until it contacts the container overshell (4).
