Collapsible container with accordion pleated sidewalls, air vent and swivel valve outlet

A collapsible container adapted to store and dispense fluid from the interior thereof, said container having means for controlling the fluid flow therefrom, said container including:

• (a) a container of fluid impervious material and having accordion pleated side portions and having a downwardly extending boss or shoulder portion which is substantially the diameter of the inner extent of the accordion pleated side portions, said container adapted to provide a storage and discharge means and while in an empty condition the container may be manipulated to bring the sides into a pleated and stacked array providing a minimun stacked height;
• (b) a top surface member integral with and forming an upper end closure of the container, said top surface member including an inlet opening for admitting fluid and a handle integrally attached to the top surface and adapted for folding flat toward and to the top surface and when swung to an erected condition providing manipulative and lifting means for the container;
• (c) a latch carried by the top surface of the container and adapted to releasably engage and retain said handle in a folded condition;
• (d) a valve and cover for said inlet opening, said valve adapted for admitting atmosphere into the filled container during withdrawal of fluid from the container and to be closed to the passage therethrough of fluid during other periods including agitation;
• (e) a bottom surface member integral with and forming a lower end closure of said container, this bottom surface member having an outlet passageway formed and provided therein;
• (f) a selective mountable swivel valve attachable to said outlet passageway, this swivel valve having two selectively movable interrelated portions with said portions in a localized contiguous relationship to each other, and when said swivel valve is mounted on the outlet passageway and the movable portion is in an attitude substantially in coincidence with the axis of the outlet passageway the swivel valve is open to fluid flow and when the movable portion of said valve is manipulated to an attitude substantially normal to the axis of said outlet passageway said swivel valve is closed to fluid flow;
• (g) an external portion formed on the body of said swivel valve, this portion extending outwardly from said body and adapted for grasping by the hand of the user, and
• (h) means for attaching a selected length of resilient tubing to an extending end of the swivel portion of said valve and when said valve is moved to a shut-off condition the tubing and swivel valve are in an attitude for coiling said tubing into a minimum of extending space.
