Description
~ ~045~84 This invention relates to devices for dispensing liquid from liquid-containing pouches.
Many liquids which were previously packaged in cans are now being packaged in pouches made from flexible material, for example plastic film. One example is motor oil. Although in many instances, special dispensing devices are not required for cans, there are cases where a dispensing device is desirable to dispense liquid packaged in a can. For example, when supplying an automobile engine with oil from a can, it is desirable to use an appropriate dispensing device with a bottom tubular outlet to properly guide the oil into the engine, and such devices have included means for opening the can when the can is inserted into the device. However, such dispensing devices which are suitable for cans are not suitable for use with flexible pouches, primarily because the opening means provided for opening cans does not satisfactorily open flexible pouches.
Pouches, being flexible, tend to deform around the opening means and/or the outlet from the devices designed for cans to undesirably obstruct the flow of liquid from the pouch. Further, dispensing
Many liquids which were previously packaged in cans are now being packaged in pouches made from flexible material, for example plastic film. One example is motor oil. Although in many instances, special dispensing devices are not required for cans, there are cases where a dispensing device is desirable to dispense liquid packaged in a can. For example, when supplying an automobile engine with oil from a can, it is desirable to use an appropriate dispensing device with a bottom tubular outlet to properly guide the oil into the engine, and such devices have included means for opening the can when the can is inserted into the device. However, such dispensing devices which are suitable for cans are not suitable for use with flexible pouches, primarily because the opening means provided for opening cans does not satisfactorily open flexible pouches.
Pouches, being flexible, tend to deform around the opening means and/or the outlet from the devices designed for cans to undesirably obstruct the flow of liquid from the pouch. Further, dispensing
2~ devices which have been proposed for use with flexible pouches, and which include opening means and a bottom tubular outlet, have suffered from the same disadvantages. In view of their flexible nature, dispensing devices are of course always ~--required for flexible pouches.
It is therefore an object of the invention to provide a device for dispensing liquid from liquid-containing flexible pouches which inclucle means for opening the pouch and a bottom tubular outlet, and which enables the liquid to fiow readily from the pouch through the outlet when the pouch has been opened by the openin~ meanG.
It is a ~urther object to provide a device which can be mounted on any pouch confining body, such as a funnel or pitcher, .
, : : . . , ~ , , 1045U~4 to facilitate rapid opening and emptying of the pouch in a convenient manner.
According to one broad aspect, the invention relates to apparatus for opening a flexible pouch of fluidal material comprising a knife member having a bracket at one end for suspending said member generally horizontally and inwardly from the wall of a pouch confining body; a pouch cutting portion at the end of the member remote from the bracket; and a portion of the member adjacent the bracket being shaped to support a pouch thereon.
When a pouch is inserted into the body through the upper opening, preferably with a small downwards push, the --~ .
knife member or members slits the pouch open as it descends.
The slit portion of the pouch moves below the knife member or members, thereby enabling the liquid to flow relatively freely -out of the pouch. Also, the flow of liquid out of the pouch releases some of the resistance to deformation of the pouch material which was present when the pouch was full, with the result that the slitting of the pouch by the knife member or r`~' ..~ ~,..
members is likely to cease, especially if a previously applied downwards inserting force is removed from the pouch. Thus, the bottom of the pouch can be halted above the bottom of the -body, so that the tubular outlet is not blocked by the pouch.
The device may have one, two or three knife members.
Where one knife member is provided, it is preferably located above the tubular outlet. Where two knife members are provided, they may be directed towards one another from opposite positions of the body. When three knife members are provided, they may ,~
be arranged parallel to one another. However, many suitable arrangements of knife members are possible.
The body may have a bottom wall which is downwardly .~", . .. .
' :.... . . . . ,. ~ . .~ i, . ...
~1~45~8~
inclined towards the tubular outlet to facilitate the flow of liquid from the body into the tubulax outlet. The body is preferably elongated in plan view, w:ith the tubular outlet being !~
located at one end of the bottom wal:L, near the side wall of the body. Also, the body preferably has a lid which can be closed when the device is not in use to reduce the risk of dirt entering the body. ~he body also preferably has a handle, and for use with viscous liquids such as motor oil, may have an annular bulge extending around the body, above the knife member or members, to obstruct flow;of liquid past the bulge towards the upper opening when the device is not in use and is lying on its side.
In accordance with another embodiment of the invention, the knife member is portable and is attachable to the upper edge of the wall of a pouch confining body such as a pitcher or the like. Fluidic material in the pouch thus is caused to empty into the pitcher, the knife member restraining the pouch above the highest level of the fluidal material is expected to reach in the pitcher, allowing later disposal of the empty pouch without the bag having been contaminated by the material, and thus without mess.
This embodiment comprises a knife member for opening ;
a pouch which contains fluidal material, comprising a shart having an upper cutting edge at least at its end, another portion of the shaft being shaped for suspension of a portion of said pouch and for allowing a cut portion of th~ pouch to drop therebelow, the other end of the shaft being shaped to allow suspension of the shaft substantially horizontally, inwardly from the wall of a pouch confining body. ;

invention.
Referring to Figures 1 to 5, a liquid dispensing device includes a hollow body 11 which is elongated in plan view, and~:
has an elongated bottom 12 which slopes downwardly to an outlet. ~.
aperture 13 at one end of the bottom wall 12 near the side wall 14 of the body 11. A curved spout 15 secured to the bottom .
wall 12 extends downwardly from the outlet aperture 13. The .
body 11 also has a handle 16 secured to the side wall 14, and :~
a lid 16A secured by hinge 17 to the top of the side wall 14.
A single elongated knife member 18 is secured to the .
interior of the side wall 14 approximately one-third of the height of the side wall above the spout 15. The knife member 18 --is blade-like with a sharpened upper edge 19 facing the top of the body 11. The knife member 18 is positioned over the outlet .. :
aperture 13 and extends just over half way across the width of .~ .
the body 11 in a substantially horizontal direction. , ~.

~, ........ .. .. . ... . .
` 1()4S~)84 flexible pouch 21 containing motor oil is lowered into the body 11, after raising the lid 16, and is then pushed downwardly to cause a knife member 18 to cut a slit 22 in the pouch ?1, i the slit 22 extending upwardly from the bottom of the pouch 21.
Since the knife member 18 is spaced above the bottom wall 12 of the body 11, the lower portion of the slit 22 travels below the knife member 18, and therefore oil can flow freely from this portion of the slit, uninterrupted by the knife member 18.
Also, provided that the pouch 21 is not forced too far downward into the body 11, the pouch 21 will be spaced above the outlet aperture 13, and therefore not impede the flow of oil from the pouch 21 to the spout 15. -when the pouch 21 is substantially empty, it can be removed from the body 11. When the device is not in use, the lid 16 reduces the likelihood of dirt entering the interior of the body 11. Also, the body 11 has an annular bulge 23 extending around its side wall 14 just above the knife member 18 to resist passage of oil beyond the bulge 23 towards the top of the body 11, when the body 11 is on its side. Figure 4 shows a liquid dispensing device which is similar to the devices of Figures 1 to 3, except that it has two knife members 24 secured to the side wall 14 at opposed positions, so that the two knife members 24 extend towaxds one another. `
Figure 5 shows a further embodiment in which three knife members 25 are provided. In this case, the three knife members 25 extend parallel to one another.
It will thus be seen that the provision of an elongated knife member or member5 spaced above the outlet aperture enables a flexible pouch to be substantially fully emptied at a reasonable rate of flow, with the flow not being appreciably interrupted either by the knife member or members or by the pouch deforming around the knife member or members or around the pouch `
outlet opening.

Figure 6 shows a knife member for opening a pouch which is mountable on a pouch confining body such as a pitcher.
Shaft 30 has an upper cutting edge 31 at least at its end, and another portion of the shaft 32 shaped for suspension of a portion of the puuch. The upper cutting edge, while shown with a blade facing upwardly, may also advantageously have simply a pointed end, adapted to slice open a pouch as it is pushed past the blade into the pouch confining body. The remainder of the shaft serves to restrain the remainder of the pouch, allowing the cut portion of the pouch to drop therebelow and pour the contents into the body on which the knife member is mounted. Thus it ;~
- may be seen that the cut flap of the pouch is effectively forced away from the resulting opening, eliminating blockage of fluid flow from the pouch into the body.
The shaft may be mounted on a bracket 33, which is shaped to fit over the edge of the wall of a pouch confining body.
Preferably, the shaft 30 is located in a position such that wh~n the entire assembly is mounted on a pitcher or the like, a portion of the pouch will be dropped below the rim thereof, allowing the 20 pitcher to restrain the pouch laterally.
Figure 7 shows the knife member mounted over the edge of a pitcher 34. It may be seen that the bracket 33 fits over the edge thereof, suspending the shaft 30 in a substantially horizontal direction. The pouch may thus be inserted into the top of the pitcher 34, pushed past the shaft 30, whereby the upper cutting edge 31 slices into the bottom portion thereof. 0 The cut portion of the pouch drops below the upper cutting edge, the remainder of the pouch being suspended by the remainder of the shaft 32, effectiv~ly opening the cut portion of the pouch, 30 allowing the contents thereof to fill the pitcher. As explained with respect to the prsvious embodi~ent, suspension can also occur with a cutting edge extending to the bracket.
It should be noted that the pitcher or other pouch !`:
confining bod~ ma~ contain various kinds of slots or other devic~s ~ C- .
~6)45~
on which the bracket 33 may be mounted. ~lternatively, the interior of the pouch confining body may have protrusions of a well known form for insertion into corresponding slots or structures in the bracket 33. Alternative structures, also within the intent of this invention can involve many cooperatively -fitting structures which will suspend the shaft 30 in a substantially horizontal direction o~ 10 to 30 degrees upward from the horizontal, inwardly from the wall of a pouch confining body.
Figure 8 shows, in a perspective view, another form of the knife member described with reference to Figure 6. In this case, the entire device is fabricated of a single sheet ~f material, and shaped into an upper cutting edge 31, a bag- ~-supporting portion of the shaft 32, and a bracket 33 which causes suspension of the cutting edge of shaft in a substantially horizontal direction when mounted on the wall of a pouch confining body. The upper cutting edge 31 is fabricated by twisting a narrowed section of the shaft portion of the device.
It may be seen that the knife member may be mounted not only on -~
~0 the edge of a pitcher, but also on funnels, tumblers, bins, -and the like. ;
In another embodiment, a shaft having an upper cutting edge has one end thereof formed to allow suspension of the shaft centrall~ into a pouch confining body. As shown in Figure 9, the one end is in the shape of a bracket adapted to be hooked over the lip of a container. The remainder forms a knife 36 having an upper cutting edge. Preferably the end of the cutting edge is formed in a point, particularly when the knife is suspended slightly vertically as at an angle of between lO to 30 degrees from the horizontal.
The knife i5 swiveled at the bracket by means of a pin or rivet 37. Therefore the cutting edge can ~e brought into parallel juxtaposition with the bracket, protectins it _7_ :
., . .. ,.~,~
1~145'~84 from nicks and protecting a user from cuts during storage.
The swiveled end of the knife 36 butts against the edge of the bracket at 38, as shown in dashed line, by which it is suspended centrally of a container into which it is hung.
Of course, nther means of suspending the knife may now become apparent to one skilled in the art. The knife may be permanently hung, or attached by swiveling means, to a bracket attached by rivets to the side of a container. The bracket could be removably attached by means of rivets through keyhole slots in the side of the container, etc While the above description has used flexible bags of oil as an example of the kinds of pouches usefully opened by this invention, it is not intended that this description be limited thereby. For instance, pouches of milk may easily be opened by this invention, the milk being accumulated in a pitcher for later dispensing. Indeed, other pouches or bags of materials may also be opened, such as water, syrup, dressings, cooking oils, anti-freeze, as well as bags of fluidic materials made of dry granular material, such as seed, fertilizer, grain, flour, etc. The bags which may be opened are preferably of flexible plastic, but other types of bags such as paper, burlap, or other textiles may also be easily opened.
