ASSEMBLY FOR CONTAINING AND DISPENSING LIQUID MATERIAL Filed Oct. 11, 1965 United States Patent Oflfice 3,2972% Patented Jan. 10, 1967 3 297,206 ASSEMBLY F012 CONTAINING AND DISPENSING LIQUID MATERIAL William R. Scholle, Long Beach, Calif., assignor to Spholle Container Corporation, Northlake, Ill., a corporation of Illinois Filed Oct. 11, 1965, Ser. No. 494,778 Claims. (Cl. 222-105) This invention relates to means for dispensing contents of packaged liquid materials wherein the packaged material is disposed in a flexible plastic container which in turn is disposed in a rigid outer container WlllCh may be of plastic or paperboard, and if desired may have an intermediate container disposed therebetween such as of k-raft paper, and is a continuation in part of my copending application Serial No. 330,702, filed December 16, 1963, now Patent No. 3,252,634.
More particularly, the present invention relates to an assembly for containing and dispensing liquid material comprising a rigid outer container and a flexible thermoplastic inner liquid container disposed therein, the inner container including a spigot adapted to project through an opening formed in the wall of the outer container characterized by means extending from the spigot to the container for yieldably permitting the spigot to be opened and for yieldably retaining it in closed non-dispensing position.
The assembly of the present invention is adapted for dispensing contained liquid which may for example be milk, water, fruit juices and the like for household use, in anincremental manner. The spigot means which is of relatively simple and economical construction, is adapted to be engaged to the outer container for anchoring the spigot on the container in dispensing position.
The assembly of the present invention is particularly adapted for storage and dispensing of liquids as aforesaid from a refrigerator wherein the entire assembly may be disposed and contents dispensed as desired or when the occasion requires.
In general, the assembly of the present invention comprises an outer container which may be of paperboard or of a plastic such as polypropylene or polystyrene or other plastic in suitable thickness to provide relative rigidity, and has disposed therein a flexible plastic bag of synthetic resinous sheet material such as polyethylene, polypropylene and the like substantially filling the confines of the outer container when substantially filled with the liquid to be dispensed. The assembly is desirably of a size which can be readily disposed on a shelf of a household refrigerator although not necessarily limited thereto.
The spigot of the present invention comprises a first tubular member having a flexible annular integral flange secured to the inner flexible container about a communicating opening, and a second tubular member telescopically en aged with the first at one end portion, the opposed outer end portion of the second tubular member being formed with a lateral aperture and an end closure.
It is an object of the present invention to facilitate dispensing and keeping the container closed when not in use and thus as previously indicated the characterizing feature of the present invention is the provision of yieldable means such as a rubber band or spring extending from the outer surface of one wall of the rigid container to the closed end of the second tubular component of the spigot and thereby adapted to hold it pressed in telescopic engagement within the first tubular component of the spigot, whereby the aperture in the second tubular member is covered by such first tubular member unless it is desired to pull the two tubes apart against the action of the spring or rubber band.
The outer rigid container of the present invention is further provided with an aperture through which the spigot may be extended and anchored against a defining portion of the outer container aperture. For this purpose the aperture in the outer container has a first portion which is of suflicient width or diameter to receive therethrough the spigot and a component annular flange, together with a relatively narrower opening portion which receives and anchors the spigot between the aforesaid and a rearwardly disposed flange for holding the spigot against displacement from the defining wall of the outer rigid container to which it is engaged, and thus against displacement inwardly or outwardly of the container.
Other objects and advantages of the present invention, its details of construction, arrangement of parts and economies thereof will be apparent from a consideration of the following specification and accompanying drawings, wherein:
FIG. 1 is a perspective view of one embodiment of the present invention.
FIG. 2 is a relatively enlarged detailed view on the line 22 of FIG. 1.
FIG. 3 is a fragmentary perspective view of a modified form of container construction.
FIG. 4 is a fragmentary perspective view of another modified form of container construction.
FIG. 5 is a further perspective view of still another modified form of container construction.
Refer-ring to the drawings, and particularly FIGS. 1 and 2, the reference numeral 10 indicates an outer container body 10 which can be composed of a relatively rigid plastic material and which may be upwardly open as shown or which may have a top cover hinged thereto in a suitable manner, not shown. Disposed within the container 10 is a flexible liquid containing liner bag 11 which when filled substantially fills the confines of the outer rigid container 10.
Secured to the liner bag 11 is a spigot composed of plastic material and comprising a first tubular member 12 engaged as by heat sealing to the liner bag 11 about an opening therein by means of the integral annular flange 13. Disposed within this first outer tubular member 12 is an inner or second tubular member 14 having a lateral aperture 15 therein and an end closure 16. Thus communication is provided from the liner bag 11 through the telescopically engaged tubular spigot portions 12 and 14 and through the opening 15 when the telescopic parts are spread apart so that the opening 15 clears the outer tube 12.
The outer tubular component 12 is further formed with a spaced pair of annular flanges 17 and 18. These flanges or at least the flange 18 is of a width such that it will pass through the widened opening portion 19 of the aperture in a wall of container 10. However, the remainder or connected opening portion 29 is narrower and just sufficient to embrace the tubular member 12 between the flanges 17 and 18 so that the spigot will become anchored in container Wall 21 and hold the spigot against displacement inwardly or outwardly of the container so that the spigot may be manipulated for dispensing purposes,
As an aid to retaining the spigot normally closed and to permit it to be yieldably opened, and to be normally closed when released, I provide yieldable means such as the flexible rubber band 22 extending from and engaged about the end closure 16 and to the anchoring lugs 23, 23 molded on the outer surface of the end wall 21.
FIG. 3 illustrates another resilient means, namely a removable or fixed leaf spring of plastic or metal 24 anchored in the holder 25 overlying the slot portion 20 in the wall 21 of the plastic container body 10, otherwise similar to that shown in FIGS. 1 and 2.
Although not shown, it will be understood that the flexible :plastic liquid container 11 can be composed of a plurality of plies of plastic material, and in the alternative although not shown the flexible plastic container 11 may be enveloped by another flexible or semi-flexible container such as one composed of kraft paper before being disposed in the relatively rigid outer container body 10.
FIG. 4 shows another modified form of construction, namely a container body generally indicated as 26 which can be composed of relatively rigid paperboard such as corrugated board, having a slot formed therein which may be in the form of a tear-out strip, not shown, and which comprises a relatively widened portion 27 adapted to receive therethrough the end 16 and flange 18 of the spigot and to anchor the spigot at the narrowed slot portion 28 in a manner previously indicated with respect to the previous figures.
In this instance, a pair of tabs 29, 29 may be struck up from the wall 30 to provide anchoring means for a rubber band or spring similar to the lugs 23, 23 shown in FIG. 2.
FIG. shows a leaf spring means engaged with a paper board carton 26. In this instance the end wall 30 is formed with an opening having a first relatively wide portion 27 and a relatively narrower portion 28 similar to that described with respect to FIG. 4 and for the same purpose. In this instance, a leaf spring 31 composed of plastic or metal is engaged through a slot 32 in the wall 30 and anchored on the wall 33 by means of the angular tab 34. The opposed free end 35 can then yieldably bear against the spigot end 16 to hold it yieldably closed and to permit it to be yieldably opened for purposes previously described.
Although I have shown and described the preferred embodiment of my invention it will be understood by those skilled in the art that changes may be made in the details thereof without departing from its scope as comprehended by the following claims.
