BY rum, arawm mmz Patented Sept. 22, 1953 PROTECTOR FOR A DISPENSING DEVICE FOR LIQUID PRODUCTS RETAINED UNDER PRESSURE IN A CONTAINER John Hcnchert, Chicago, Ill., assignor to Continental Can Company, Inc., New York, N. Y., a

corporation of New York Application July 13, 1950, Serial No. 173,646

1 Claim. 1

The invention relates to new and useful improvements in a protector for a dispensing device for liquid products retained under pressure in a container. In my copending application Serial No. 39,525 filed July 19, 1948, now Patent No. 2,623,785, there is shown a dispensing container for products of the above type wherein the valve is opened for dispensing purposes by pressure applied to a flexible disk forming a part of one of the walls of the valve body. The disk is exposed and if pressure is accidentally applied thereto, the valve will be opened and the product dispensed until the disk is released or the pressure within the container is exhausted.

An object of the present invention is to provide a protective means permanently secured to the container and covering the flexible disk to prevent pressure from being accidentally applied thereto which protective means includes a removable member overlying the flexible disk and dispensing nozzle for giving access thereto for dispensing purposes.

A further object of the invention is to provide a protective means for a dispensing container of the above type which includes a member conforming in shape to the outer face of the container end and permanently attached to the end seam, which member has a central opening surrounded by an upstanding neck within which is disposed the valve body and flexible disk, said protective means also including a cover member pivotally attached to the neck and overlying the disk for giving access thereto for dispensing purposes.

In the drawings, which show by way of illustration one embodiment of the invention:

Figure 1 is a vertical sectional view of a dispensing container with the improved protective means applied thereto;

Figure 2 is a plan view of the same;

Figure 3 is a vertical sectional view through the valve body showing the arrangement of the flexible disk which opens the valve when pressure is applied thereto;

Figure 4 is a plan view of the cover member and the hinging means associated therewith detached from the container.

The container to which the invention is applied includes a body portion I, an end portion 2 secured to the body portion by a double seam 3 of the usual construction. This end portion 2 is concave as viewed from the outside of the container. At the center thereof is an opening and attached to the container end at said opening is a valve body 4. The valve body has an opening extending from the lower end thereof to the upper end and a partition member 5 separates this opening into two chambers, an upper and a lower chamber. A nozzle 6 is attached to the valve body and has an opening leading to the upper chamber. The upper side of the upper chamber is closed by a flexible disk I secured thereto by a ring member 8 carrying the nozzle 6.

At the lower side of the partition 5 is a valve seat 9 with which a valve it! makes contact. Within the lower chamber is a rod H surrounded by a spring i2 which is placed under tension and operates to hold the valve normally closed. Within the upper chamber is a stem it havin a flat head I4 which lies close to the inner surface of the flexible disk 1. When pressure is applied to the disk the valve will be opened and the product under pressure from the container will flow into the upper chamber and be dis- Densed through the opening in the nozzle. For a further detailed description of the dispensing device reference may be made to the copending application supra.

The specific features of the dispensing nozzle form no part of the present invention. The broad features, however, of a dispensing device having a valve which is opened by finger pressure applied to a flexible disk forming a wall of the valve body does have an important bearing on the present invention which relates to a protective means permanently secured to the container and covering this flexible disk to prevent accidental pressure being applied thereto. This protective means includes a member I5 which is shaped to conform to the outer surface of the container end 2; said member I5 extends over the end seam as indicated at 16 and is provided with a depending flange I! which is adapted to be turned underneath the end seam for permanently attaching this member IE to the container. The member I5 has a relatively large central opening surrounded by an upstanding neck [8 which is rolled outwardly into a hollow bead 19. When this member I5 is attached to the container the valve body 4 and the flexible operating disk 71 are disposed within this neck portion. These parts are preferably dimensioned so that the flexible disk lies slightly below the plane passing tangentially across the upper extreme of the end seam. Associated with this member I5 is a cover member 2!} which has a depression in the outer face thereof forming a friction wall 2! which is adapted to engage within the neck Hi.

The central portion of the cover extends inwardly and upwardly and the central portion is domed as indicated at 22 so as to overlie the flexible disk I. The flange of the cover is turned underneath as indicated at 23 for the purpose of strengthening the cover. At one side of the cover there is a projecting portion 24 which is rolled into a bead and is adapted to receive a bracket member 25. The bracket member 25 extends straight through the rolled bead 24 and is provided with arms 26, 26 having the ends thereof 21, 2'! turned outwardly. These arms are adapted to embrace the neck portion of the member i and thus the cover is attached to the neck portion so that it may sWing on the pintle portion 28 of the bracket member 25. When the cover is in closed position as shown in Figure 1, it will be retained in this position by the friction wall 21 engaging the inner surface of the neck It. In this closed position the domed portion 22 of the cover is spaced slightly away from the flexible disk 1.

The cover is made of comparatively heavy metal so that if there is accidental contact with the cover it will not spring so as to flex the disk and open the valve. The cover is likewise slightly below a plane tangential to the end seam so that one can can be stacked on another without pressure being applied to the cover.

A dispensing container with this protective means applied thereto can be packed in a handbag 01' packed for shipment and may be stored without fear of the flexible disk being accidentally pressed upon so as to open the valve and bring about undesirable dispensing of the liquid contents therein. When it is desired to use the container for dispensing the liquid therein the hinged cover is swung on its pintle to open posi- 4 tion and this gives ready access to the flexible disk and the nozzle so that dispensing can be accomplished as desired.

It is obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of the invention, as set forth in the appended claim.

I claim:

A dispensing device for liquid products retained under pressure in a container comprising a valve body, a dispensing nozzle carried thereby, a valve, a flexible disk forming a wall of the valve body, devices within the valve body operated by pressure applied to the disk for opening the valve, and a protective means permanently secured to said container and covering said disk to prevent accidental pressure thereon, said protective means including a member conforming in shape to the outer face of the container end and permanently attached to the end seam, said member having a central opening surrounded by an upstanding neck within which is disposed said valve body and flexible disk and a cover member pivotally attached to said neck and overlying the disk for giving access thereto for dispensing purposes.
