Dispensing package

摘要

A dispensing package for cosmetic creams is disclosed. The dispensing package includes a container body having a first end and a second end. The container body includes a first inner perimeter adjacent the first end and a second inner perimeter adjacent the second end, wherein the first perimeter is larger than the second perimeter. The dispensing package also includes an elevator positioned within the container body for movement between the second end of the container body and the first end of the container body to force material held within the container body out the first end of the container body. The elevator includes an outer surface facing an inner wall of the container body and a sealing bead formed on the outer surface of the elevator. The sealing bead engages the inner wall of the container body adjacent the second end of the container body to form a seal permitting filling of the dispensing package and containment of product volatiles during storage and distribution. The sealing bead disengages from the inner wall of the container body where the second inner perimeter transitions to the first inner perimeter to provide pressure relief from the seal and a free-floating elevator as the elevator moves from the second end of the container body toward the first end of the container body.
