PLASTIC AEROSOL CONTAINER

摘要

A plastic aerosol container comprising a neck, a support ring, a shoulder, a cylindrical body, a base, a dispensing valve and a cap. The neck further includes a lip and a lip cavity. The support ring protrudes below the lip cavity and above the shoulder. The shoulder supports the neck and aides in preventing deformation of the container. The base further includes legs. The dispensing valve is placed atop the neck and sealed thereto. The cap is placed atop the valve and functions as an actuator to release the contents of the can.

主权项

1. A plastic aerosol container, comprising:
a cylindrical body extending about a longitudinal axis; a shoulder having a top end and a bottom end, wherein the bottom end of the shoulder is connected to a proximal end of the cylindrical body, wherein the shoulder has a arcuate cross-sectional shape in which the outside diameter of the shoulder decreases continuously from the bottom end to the top end, and wherein the top end of the shoulder has a first material thickness in a plane transverse to the longitudinal axis of the cylindrical body; and a neck connected to the top end of the shoulder and extending longitudinally therefrom, the neck having a substantially planar inner surface, wherein the neck further comprises:
a support ring, wherein the support ring is positioned adjacent the top end of the shoulder and extends substantially transverse to the longitudinal axis to overlie a portion of the shoulder, and wherein the support ring has a second material thickness extending from the inner surface of the neck to a support ring outer edge in a plane transverse to the longitudinal axis of the cylindrical body that is greater than the first material thickness;a lip positioned at a proximal end of the neck and extending substantially transverse to the longitudinal axis to position a lower surface of the lip in overlying relationship to a top surface of the support ring, wherein the lip has a third material thickness extending from the inner surface to a lip outer edge in a plane transverse to the longitudinal axis of the cylindrical body that is greater than the first material thickness and less than the second material thickness; anda lip cavity defined between the lower surface of the lip and the top surface of the support ring.
