Description

June 21, 1966 L. A. MICALL EF PRESSURE DISCHARGE CONTAINER Filed May 15, 1963 FIG.

INVENTOR. LEWIS A. MICALLEF A TTORNE YS'.

United States Patent Oflice 3,257,036 PRESSURE DISCHARGE CONTAINER Lewis A. Micallef, New York, N.Y., assignor to Leeds and Micallef, New York, N. a partnership Filed May 13, 1963, Ser. No. 280,038 2 Claims. (Cl. 222-95) This application is a continuation-in-part of my application Serial No. 594,415, filed June 28, 1956, now Patent No. 3,089,624, issued May 14, 1963. In that application I have shown and described a pressure discharge container wherein the commodity marketed is contained in a flexible bag which is enclosed in a pressure-tight metal container containing compressed gas which, when the valve controlling the exit of the bag is open, compresses the bag and forces the contents out through the exit opening. Such containers were proposed before my above-mentioned application, but none .had been found satisfactory because of the tendency of the flexible wall of the bag when vpressed inwardly duringthe discharge operation to cutoff the discharge opening and prevent the further discharge of the bag contents.

"The above-mentioned application is directed to the preferred form of my invention wherein a bag of novel construction is employed, which bag is so designed that the walls of the bag will not contact the discharge opening until the contents of the bag are substantially exhausted. In such application as originally filed, I also disclose a modification of my invention which secured in large measure a complete discharge of the contents of the bag when employed with any type of flexible bag. This application relates to that alternate form of the invention. In the accompanying drawings I have illustrated the alternate formof the invention as shown in the abovementioned application and a modification thereof, as will be later described.

In the said drawings:

FIG. 1 shows in vertical section the modified form of pressure discharge container as disclosed in my previous application;

FIGS. 2 and 3 are detailed views of the bag covered by the above-mentioned application; and

FIG. 4 is a vertical sectional view of a modification for use with conventional aerosol containers.

Referring to the drawings, particularly to FIG. 1, 1 indicates the outer container which, as shown, consists of a metal can of suflicient strength and rigidity to withstand the internal pressure. 2 indicates the end cap of the outer container which is attached to the neck of the body portion by the usual rolled seam.

Fixed in the center of the cap 2 is a tubular stem 3 containing the discharge valve 4, and fitted to the neck of the outer container is a cover 5 of rubber or other flexible material, through which the valve, is controlled in the usual manner. The stem 3 also serves as a support and attachment for the bag 6. As shown in FIG. 1, the bag '6 has a neck 7 which fits over an inner tube 8 which projects above the neck 7 and extends upwardly into the stem 3.

The bag 6 may be of the novel construction covered by my above-mentioned application, shown in FIGS. 2 and 3, or of any desired form, spherical, for example, and of a capacity when filled with liquid to occupy not less than three quarters the internal space of the outer container. The bag may be of any flexible,-'liquid-tight material.

. The inner tube 8 is a thin walled tube'of plastic or metal and extends almost to the bottom of the outer container. A'- series of vertical slots 9 are cut or molded in the 'wall of the tube 8, the slots being distributed throughout the length and circumference of the tube.

1 have found in.v practice that the flow .of liquid from ter, when flat, substantially greater than the diameter ofthe above described container will not be interrupted untilfl virtually the entire contents of the bag have been discharged. This is so because the distribution of the slots is such that all of them will not be cut off unless portions of the bag wall throughout the entire circumferenceby my above-mentioned application. This bag consists of two disks 10 and 11 of flexible plastic or other suitable material cemented together at their perimeters to form a circular rim of greater diameter than the diameter of the outer container so that when the bag is enclosed in the outer container the rim, which is somewhat stiffer than the walls of the bag, will hold the mid-portion of the bag distended until the contents of the bag are discharged. The upper disk 10 has a central neck 12 for connection with the inlet of the discharge valve of the container.

In FIG. 4 I have shown a modified form bag and tube combination designed to be used in the conventional aerosol container without change in the shape or dimensions of any of the parts. In practically all of the aerosol containers now on the market, the inlet to the discharge valve is a short, tubular section 16 projecting downwardly from the top cap of the can and fitted with a dip tube extending to the bottom of the can. In place of this dip tube I substitute the bag and tube combination shown in FIG. 4.

The bag of FIG. 4 is the bag of my above-mentioned application, except that it contains a discharge tube of suflicient length to reach almost to the bottom of the a diameter to fit snugly on the upper portion 13 and sufli-' ciently stiff to hold the two portions of the bag apart, as shown in FIG. 4. The tube 14 is perforated throughout its length with staggered holes 15 to insure an uninterrupted flow of liquid to the discharge valve until 'the bag is fully collapsed.

I claim:

1.' A pressuredischarge container comprising an outer container containing fluid under pressure, an inner bag of flexible sheetmatcrial for the commodity, a discharge valve having an inlet passage, said bag being secured at the valve only and consisting of two substantially circular portions and a connecting portion' at the perimeters of the circular portions, said connecting portion being less flexible than the circular portions, and a tube in said bag extending from said passage to a point near the bottom of said outer container, said tube having a plurality of elongated longitudinal slots in its wall, said slots being circumferentially and longitudinally staggered throughout its length.

2. A pressure discharge container comprising an outer container containing afluid under pressure, an inner bag having a discharge passage, said inner bag consisting of two substantially circular portions of flexible sheet material and a connecting portion at the perimeters of the circular portions, said circular portions being of a diamesaid outer container, anda tube in said bag extending from said passages to a point near the bottom of said outer container, said bag being secured to said tube at said'discharge passage only, said tube having circum- Patented June 21, 1966 3 e r .4 fcrentially and longitudinally staggered openings in its FOREIGN PATENTS wall throughout its length. 1
