Abstract
The invention relates to a pressure operated valve on a flexible container. Prior closures are generally manually opened before inverting the container to dispense. The fluid pressure opened reclosable spout (10) for flexible container (14) includes a sleeve assembly axially inserted into the exit end (16) of the pouring spout. The assembly comprises a first sleeve (20) bonded to the inner surface of the spout of the exit end (16) which contains an annular inwardly projecting flange-like wall (26) slidably receiving a piston sleeve valve (28) normally sealing with the outer end of the first sleeve and biased to an open position by a spring (36) or weight (33). The wall of the piston sleeve valve includes, adjacent its outer end, circumferential apertures (42) for discharging liquid when the piston sleeve valve is opened by fluid pressure upon squeezing the container.
Description
LIQUID PRESSURE OPENED POURING SPOUT
Technical Field This invention relates to flexible plastic wall liquid containers and more particularly to a valve equipped pour¬ ing spout opened by squeezing the side walls of a full con- tainer.
There are many circumstances when an extension such as an attached spout or funnel is either necessary or desired to avoid spilling when pouring liquids from a portable con¬ tainer into another container, a vehicle engine, or the like.
These devices help but are often inadequate for the reason the liquid starts to flow as soon as the container is partially inverted, after being opened and before it is properly positioned for discharge of the liquid. A The recent proliferation of flexible plastic contain¬ ers for lubricating oil and liquids of all descriptions, has made it apparent that a reusable extension with a valve closure at its exhaust end that can be remotely opened by liquid pressure generated by squeezing the container walls would be very desirable. This invention provides a contain¬ er spout which permits the user to position the end of the spout in the receiving opening with the portable container inverted before generating liquid flow by squeezing the container walls. Background Art
The prior art discloses a multitude of container spout or open top container closing members generally formed by thin wall cap members either overlying the periphery or
-2-
discharge end of the pour spout or inserted in a snap ac¬ tion into a groove within the inner periphery of the pour¬ ing spout.
Such container closing members are generally satisfac- tory where the opening is to be manually opened before in¬ verting or partially inverting the container for pouring. However, such a closure member would result in unwanted sudden discharge of a considerable amount of the liquid from a flexible wall plastic container if such a spout seal was opened by pressure on the container walls.
This invention is distinctive over these prior con¬ tainer neck or spout closures by providing a pouring spout which includes a piston valve in its exhaust end normally seated in a spout closed position but liquid pressure moved in an outward direction by pressure applied to plastic con¬ tainer walls moving the piston valve to a valve open posi¬ tion for discharging liquid from the container.
Disclosure of the Invention The inner wall surface of the exit end of a container pouring spout is provided with an inwardly projecting ledge forming an annular wall spaced inwardly from its exhaust end surface. The pouring spout inner wall is further pro¬ vided with a verge or annular part circular recess forming a valve seat. A piston sleeve valve is axially received by the exhaust end portion of the pouring spout.
The piston sleeve valve is characterized by an outward closed end having an annular outstanding flange in the plane of its closed end and having an outstanding flange at the inner end limit of the piston. Adjacent its outwardly disposed end, the piston sleeve valve wall is provided with a plurality of apertures and the inward end portion of the piston wall is provided with a plurality of slots open through its inner end edge.
In one embodiment, the piston valve is normally biased outwardly to a spout open position by a spring surrounding the piston valve within the spout.

The Best Mode For Carrying Out the Invention In the drawings:
Referring first to Figures 1 through 5, the reference numeral 10 indicates one embodiment of the pouring spout connected with the spout or neck 12 of a flexible wall sub¬ stantially conventional container 14.
The spout 10 is formed from tubular material such as plastic and may be of any desired length and capable of being flexed or bent or including an accordion-type wall intermediate its ends to facilitate a bending action be¬ tween the container connected end and its pouring spout end 16.
The spout 10 is connected with the container by an internally threaded nut 18 or the like engaging the threads, not shown, of the container neck 12.
An open end sleeve 20 having a length at least equal to its diameter is disposed in contiguous wall contact with the inner wall surface 22 of the pouring spout end portion 16. The sleeve 20 is provided at its outward end with an outstanding flange -24 overlapping the end wall edge of the pouring spout end portion 16, the sleeve being bonded to the inner wall surface 22 in liquid-tight relation. Inter¬ mediate its ends, the sleeve 20 is provided with an inward¬ ly projecting flange forming an annular stop 26 projecting inwardly a selected distance normal to the inner wall sur¬ face of the sleeve. Obviously the sleeve 20 could be manu¬ factured as an integral part of the spout wall end portion 16 if desired.
A piston sleeve valve 28 is axially received for long- itudinal sliding movement by the wall sleeve 20. The out¬ wardly disposed end of the piston sleeve valve 28 is closed by an end wall 30 which radially projects beyond the outer perimeter of its sleeve portion to form an ou standing flange valve 32 projecting beyond the cylindrical plane of the piston sleeve valve a distance substantially equal to the radial width of the stop 26.
Similarly the inward end portion of the piston sleeve
valve 28 is provided with an outstanding wall flange 34 dimensioned substantially equal with respect to its out¬ standing flange valve 32 and slidably contacting the inner wall surface of the wall sleeve 20 so that the annular stop 26 and the outstanding wall flange 34 form a guide for maintaining the piston sleeve valve in axial alignment with the pouring spout wall end portion 16 as the piston sleeve valve is opened and closed as presently explained.
A helical spring 36 surrounds the piston sleeve valve 28 between its outer end flange valve 32 and the wall sleeve annular stop 26 for biasing the piston sleeve valve outwardly of the spout end portion 16. As clearly shown by Fig. 4 the inner wall surface of the wall sleeve 20 adja¬ cent its outer limit is provided with a part circular re- cess 38 for cooperatively receiving the part circular outer edge surface of the piston sleeve valve flange 32 to form a liquid-tight seal for the reasons presently apparent.
Alternatively, the sleeve end wall valve flange 32' may be provided with a part circular, in transverse sec- tion, annular recess 32" and a verge 40 may be formed on the inner surface of the sleeve wall 20 at its outer end for nesting the piston sleeve valve end wall flange 32 ' in liquid-tight seal relation.
The piston sleeve valve 28 is further characterized by a circumferential row of apertures 42 in its wall adjacent its closed end 30 for discharge of liquid, not shown, from the container 14 when the piston sleeve valve is in open position (Fig. 3). The inner end portion of the piston sleeve valve wall is longitudinally open-end slotted, as at 44, through its flange 34 in circumferentially spaced rela¬ tion for bending this slotted wall end portion inwardly in a collapsing action upon itself to facilitate insertion of the piston sleeve valve 28 into the wall sleeve 20.
Referring also to Figures 6, 7 and 8, the reference numeral 10' indicates another embodiment of the pouring spout similarly formed from plastic tubing material having a discharge end portion 16' and a threaded nut portion 18'
for connection with the neck 12 of the container 14.
In this embodiment the spout end wall portion 16' is thickened to form an inner diameter 21 adjacent its exit end substantially equal to the outside diameter of the pis- ton sleeve valve 28' for slidably supporting the piston sleeve valve 28 and forming an annular inwardly facing shoulder to prevent movement of the piston sleeve valve out of the pouring spout.
In this embodiment the piston sleeve valve 28' is pro- vided with a cup-like end wall 31 secured by its perimeter to the outer end surface of the piston sleeve valve flange
32 (Fig. 8) to form a closed compartment filled with dense metallic material 33.
The mass of the metallic material 33 at least in part compensates for the spring in the embodiment of Figs. 1-5 in biasing the piston sleeve valve 28' outwardly in re¬ sponse to a manual squeeze on the walls of the container 14 to open the piston sleeve valve.
Referring also to Figures 9, 10 and 11, the sleeve wall and piston sleeve valve may be inserted as an assembly 45 into the neck 12 of a conventional container 14 and held in place by an open end cap-like ring 50.
The cap ring 50 open end or top may be further sealed by a removable conventional thin shipping seal 52, circular in configuration, overlying the open end of the cap ring and sleeve and valve assembly 45 for sealing the fluid in the container 14.
At the time of αse, the seal 52 is manually removed so that pressure on the container walls 14 opens the piston sleeve valve to the position shown by Fig. 11.
Referring also to Figures 12 and 13, the numeral 60 indicates another embodiment of the piston sleeve valve and wall sleeve assembly which dispenses a measured prede¬ termined quantity of liquid from a container when the flex- ible walls thereof are squeezed to open the valve assembly 60.
In this embodiment the wall sleeve 62 is provided with
ar: inner end flange 64 projecting radially inward a dis¬ tance substantially equal to the radial thickness of the sleeve wall stop 26. This sleeve wall flange 64 is pro¬ vided with an annular valve seat 66 facing toward its sup- porting container.
The piston sleeve valve 68 is similar to the piston sleeve valve 28 having an outer end closing wall 70 and row of liquid discharge apertures 71 with the exception that the inner end of the wall of this piston sleeve valve is closed by an end wall 72 and valve seat 73 similar to the opposite or outer end wall 70 and seating on the valve seat 66. The inner end portion of the wall of the piston sleeve valve 68 is provided with a circumferential row of aper¬ tures 74. The piston sleeve valve 68 is further character- ized by an annular outstanding flange 76 spaced toward its outer end wall 70 from its inner end wall 72 a distance at least twice the diameter of each aperture of the row of apertures 74 for the purposes presently apparent. A helical spring 78 surrounds the piston valve 68 between the wall sleeve flange 64 and the piston valve sleeve flange 76 for normally urging the piston sleeve valve 68 in an outward direction. The outer closed end wall 70 of the piston sleeve valve 68 is similarly provided with a valve seat on its perimeter flange 80 sealing with the inner wall surface of the sleeve wall 62 as shown by Fig. 12. When the sleeve valve assembly is in its container closed position of Fig. 12 it contains a predetermined quantity or volume of fluid to be dispensed from the container with which the assembly is connected. When the flexible walls of the container are manually squeezed the liquid forces the piston sleeve valve 68, to its outwardly disposed open position of Fig. 13. The fluid contained in the area defined between the piston sleeve valve ends 70 and 72 and the wall of the sleeve valve 68 is exhausted through its outer end apertures 71 into a suitable receptacle, not shown.
During the quick opening action of moving the piston sleeve valve 68 from its closed to its open position, some
-8-
liquid will move through the inward end apertures 74 and outward apertures 71. Such quantity of liquid is closely estimated in arriving at the dimensions of the piston sleeve valve for the quantity of liquid desired to be dis- pensed at each opening of the valve assembly. If a second similar quantity of liquid is to be dispensed the piston valve 68 is moved from its liquid discharged and container closed position of Fig. 13 to the sleeve assembly fill pos¬ ition of Fig. 12 with the container with which the valve assembly 60 is connected held in an upright position. Thereafter the above opening and dispensing action is re¬ peated.
A further modified form of the liquid pressure re¬ leased pouring spout valve is illustrated by Figure 14 which permits automated filling of the container 14 and placing a cap thereon.
The container cap, indicated at 50', has internal threads 84 cooperatively received by the external threads 86 of the container neck 12. The closed end of the cap 50* is centrally bored on a diameter substantially equal with the diameter of the pis¬ ton valve sleeve 28 and the inner wall surface defining the bore is provided with an annular groove 88 arcuate in transverse section for the purposes presently explained. The end wall of the container cap 50' is thickened relative to the thickness of its threaded wall and provid¬ ed with an annular recess 90 for cooperatively receiving the chamfered edge of the flange 24' of an open end sleeve 20' similar to the open end sleeve 20 of Fig. 2. The open end sleeve 20' similarly has an inwardly projecting flange 26' medially its ends. The outer end portion of the open end sleeve 20' nas its wall provided with a plurality of longitudinally extending slots 92 open toward the outer end of the open end sleeve to permit flexing its flanged end inwardly to insert its flange 24' into the cap recess 90.
A modified form of the piston sleeve valve of Figures 2 and 3, indicated at 93 is similarly provided with an out-
standing annular valve 94 having an arcuate perimeter seal- ingly received by the groove or valve seat 88 for closing the pouring spout neck 12.
The inward end of the piston valve sleeve is provided with an annular outstanding flange 34' having a chamfered edge to facilitate its insertion into the open end sleeve 20' beyond its inward flange 26'. Similarly, the inward end portion of the piston sleeve valve wall is slotted, as at 44', for inserting the piston sleeve through the open end sleeve 20' .
The outward end portion of the piston valve sleeve is provided with a diametrically opposite pair of fluid dis¬ charge wall apertures 95.
Similarly, the spring 36 is interposed between the sleeve flange 26' and the piston valve closed end flange 94 for assisting liquid pressure biasing the piston valve out¬ ward to its opened dotted line position.
