ABSTRACT OF THE DISCLOSURE
A flexible self-standing pouch made from at least one layer of plastic material bonded to form a closed inner chamber for storing liquid. Peripheral portions of the wall material are cortoured and then bonded to form a closed pouring spout at a corner of the pouch. The configuration of the spout is defined by the contour of the sealing in the vicinity of that pouch corner. The pouring spout is opened by cutting the pouch corner at an angle. The bonded peripheral edge has a generally rec-tangular contour except for an inwardly curved portion cor-responding to a recess in the wall material, which recess partly defines the spout configuration. This recess has a maximum height which is greater than the maximum depth measured in a direction transverse to the direction along which the height is measured. Further, the recess may either begin at the top of the pouch or at a point along the side which is spaced from the top.
A juncture portion along the top of the pouch and a juncture por-tion along the rim of the recess define the configuration of the open pouring spout, which open spout is intended to be inserted in the open neck of a container to be filled.

Description
-- IR ~6 FLEXIBLE POUCH CONTOURED TO FACILITATE POURIMG
FIELD OF THE INVENTION
This invention relates to a flexible pouch made of laminated material used for refilling other containers.
BACXGROUND OF THE INVENTION
The use of flexible pouches liquids made of laminations of plastic material to dispense liquids is well known. One such pouch is disclosed in U.S. Patent No. R~ 24,251.
A pouch made of metallic foil and having a contoured pouring spout is disclosed in U.S. Patent No. 3,907,164. How-ever, this conventional package has a reduced storage capacity due to the shape of the container and has no means for facilitat-ing the pouring of liquid from the container into the neck of an-other container. The latter disadvantage is because when the pouch is turned to the pouring position, its pouring spout does not make use of the contoured configuration. On the contrary, the contour merely serves to define the pouring spout and not to receive the neck of another container.
SUMMARY 0~ T~IE INVENTION
The object of the invention is to overcome the foregoing disadvantages of conventional pouch for storing li~lids. -.
Mor~ specifically, it is an object of the invention to provide a heat-sealed pouch which has a contoured configuration C~ r~ ~, which facilitates the pouring of liquid from the pouch into an~
other container.
It i~ a further object of the invention to provide a pouch having a spout which can be mass-produced from webs of sheet-like material with a minimum of wasted material.
The invention is a self-standing flexible pouch made from at least one layer of plastic material heat-sealed to form a closed inner chamber for storing liquid. Alternatively the pouch in accordance with the invention may have laminated walls com-prising a layer of foil adhered to a layer of plastic.
A pouch in accordance with the preferred embodiments of the invention has a peripheral edge formed by fin sealing two layers of wall material together. In accordance with one prefPrred embodiment, two sheets of wall material are fin-sealed together along their entire peripheries. In accordance with an other preferred embodiment, one portion of the peripheral edge of a folded single sheet of wall material is fin-sealed to the remaining portion of the peripheral edge of that single sheet.
A self-standing pouch in accordance with the preferred embodiments of the invention is gusseted at its bottom to enable the pouch to stand in an upright position when filled with liq uid. -:
Peripheral portions of the wall material are contoured and then heat-sealed or adhered to form a closed pouring spout at a corner of the pouch. The configuration of the spout is defined by the contour of the heat sealing or adhesion in the vicinity of that pouch corner. The pouring spout is opened by cutting the pouch corner at an angle.
In accordance with the preferred embodiments of the in-vention, the juncture has a generally rectangular contour, except for an inwardly curved portion which defines at least a portion of a recess in the pouch wall. This recess in turn defines a part of the spout configuration. The recess has a maximum height which is greater than the maximum depth measured in a direction transverse to the direction along which the height is measured.
In accordance with one preferred embodiment, the recess may begin at the top of the pouch. In accordance with another preferred embodiment, the recess may begin at a point along the side which is spaced from the top.
In accordance with the preferred-embodiments of the in-vention, a juncture portion along the top of the pouch and a juncture portion along the rim of the recess define the con-figuration of the open pouring spout, which open spout is in-tended to be inserted in the open neck of a container to be filled.
In accordance with one preferred embodiment of the^-lnven-tion, a second recess is formed on the opposite side of the pouch, thereby defining a second closed pouring spout.

FIG. 5 is a partial side. view of the flexible pouch of FIG. 4 with the spout open and a partial sectional view of the neck of a container to be filled in which the open spout has been inserted. --FIG. 6 is a perspective view of the flexible pouch ofFIG. 4 with the spout open.
~ r r DETAITED DESCRIPTION OF THE PREFERRED EMBODI~:NTS
In accordanc~ with the first preferred embodiment of the invention depicted in FIGS. 1-3, pouch 10 is constructed from two sheets 12 of flexible wall material which are sealed together along their peripheral edges to form a closed inner chamber for holding liquid. The wall material is preferably transparent or translucent plastic of a type which will not react with the in-gredients in the liquid to be stored in the pouch chamber.
During manufacture, two sheets 12 of wall material having the same shape are arranged against each other with their peripheries mutually overlapping. The corresponding peripheral edyes 14, 16, 18 and 20 are bonded by heat sealing, sonic weld~
ing, adhesive or like means to form a closed inner chamber of the pouch. The bottom edge 20 is gusseted along contour 22 to enable the pouch to stand upright when filled with liquid.
Alternatively the chamber could be formed from a single sheet of wall material by folding the wall material and then bonding the overlapping portions of the periphery of the single sheet.
After the first bonding operation, a recess 24 is fo~ned in the respective sheets of wall material by cuttiny alony side peripheral edge 16. This recess has a maximum height which- is greater than the maximum depth measured in a direction transverse to the direction alon~ which the height is measured. Further, in 3,~
accordance with the first preferred embodiment of the invPntion, the recess begins at the top of the pouch. After recess 24 is formed, the respective sheets of wall material are bonded along the rim of the recess to again close off the pouch chamber.
In accordance with the first preferred embodiment of the invention, the bonded edge of the recess has a generally inwardly curved portion 28 with generally straight portions 30 and 32 ex-tending kherefrom.
Recess 24 defines a closed pouring spout 34. As can be seen in FIG. l, the closed spout 34 can be rounded to improve the strength and appearance of the spout.
The contour depicted in FIG. 1 maximizes the storage ca-pacity of the pouch, enhances the structural strength at the pouring spout and permits refilling of containers having necks of different diameters.
FIG. 2 depicts the refilling of a container 40 by insert-ing the open spout of pouch 10 in open neck 42. Spout 34 is opened by cutting along line A--A (see FIG. 1). Cut A--A should be made at an angle of 30 to 60 degrees with respect to the top peripheral edge 18, preferably 45 degrees. A 45-degree cut permits the liquid contents of the pouch to be readily drained through spout opening 44 and into neck 42 of container 40.-In accordance with the first preferred embodiment,generally straight portions 30 and 32 lie at an angle of between 25 and 30 degrees relative to the side peripheral edge 16. How-~ver, portions 30 and 32 can lie at an angle of less than 25 de~
grees relative to the side peripheral ed~e 16. However, as the angle of portion 30 relative to edge 16 is decreased, the angle between portion 30 and top edge 18 is correspondingly increased.
In turn, a wider angle between portion 30 and top edge 18 means that spout opening 44 can be inserted into neck 42 of container 40 to a corresponding lesser depth. Since spout 34 is flexible, the greater the depth of insertion of spout opening 44 into neck 42, the lesser the risk that spout opening 44 will fall out of neck 42 in the event that pouch 10 is jostled during refilling of container 40. Thus a smaller angle between portion 30 and edge 1~ will reduce the risk of spillage for a given neck diameter of the container being refilled.
In accordance with the second preferred embodiment of the invention depicted in FIGS. 4-6, pouch 110 is constructed from two sheets 112 of flexible wall material which are bonded togeth-er along their peripheral edges to form a closed inner chamber for holding liquid. The wall material is preferably transparent or translucent plastic of a type which will not react with the ingredients in the liquid to be stored in the pouch chamber.
During manufacture, two sheets 112 of wall materiai-hav-ing the same shape are arranged against each other with their peripheries mutually overlapping. The corresponding peripheral ) IR 4684 edges 114, 116, 118 and 120 are bonded by heat sealing, sonic welding, adhesivP or like means to form a closed inner chamber of the pouch. The bottom edge 120 is gusseted along contour 122 to enable the pouch to stand upright when filled with liquid.
Alternatively-the chamber could be formed from a single sheet of wall material by folding the wall material and then bonding the overlapping portions o~ the periphery of the single sheet.
After the first bonding operation, recesses 124 and 125 are formed in the respective sheets of wall material by cutting along side peripheral edges 112 and 116 respectively. Each recess has a maximum height which is greater than the maximum depth measured in a direction transverse to the direction along which the height is measur~d. Further, in accordance wi~h the second preferred embodiment of the invention, each recess begins at a point spaced from the top peripheral edge 118 of the pouch.
After recesses 124 and 125 are formed, the respective sheets of wall material are bonded along the edges 126 and 127 respectively of the recesses to again clos2 of f the pouch chamber.
In accordance with the second preferred embodiment of the invention, the bonded edges 126, 127 of the rPcesses 124, 125 have a generally semicircular shape. Recesses 124 and 12S -respectively define closed pouring spouts 134 and 135.
FIG. 5 depicts tha refilling of a container 140 by in-serting the open spout of pouch llO in open neck 142. Spout 135.
is opened by cutting along line B--B (see FIG. 4). Cut B--B
should be made at an angle of 30 to 60 degrees with respect to the top peripheral edge 118, preferably 45 degrees, and should be placed so that top peripheral edge 118 and the rim 127 of recess 125 are both cut. A 45-degree cut permits the liquid contents of the pouch to be readily drained through spout opening 144 and into neck 142 of container 140.
In accordance with the second preferred embodiment, recess 125 is spaced relative to top peripheral edge 118 such that spout opening 144 has the desired dimension when cut ~--B is made. This also applies to the spacing of recess 124 from top peripheral edge 118.
The provision of a second recess 124 is advantageous, but is not essential to the invention. However, because of the col-lapsible nature of a pouch made of fl~xible sheets of wall material, folds in the pouch can entrap some fluid so that the trapped fluid will not drain out open spout 1~40 In that event, spout 134 can be opened by cutting to provide an alternate path for dxainage of the previously trapped fluid from pouch 110 into the container to be refilled.
The second recess can be formed simultaneously with formation of the first recess in the pouch. Moreover, if-t-he pouches are formed in succession by bonding sheet material un-rolled from continuous webs, the recesses in different pouches can be advantageously formed simultaneously.
~ 3 IR 4684 Numerous modifications are possible in light of the above disclosure. For example, the preferred pouch 10 includes sheet walls 12 which are bonded together at their peripheral edges 14-20 to define an inner chamber. A bottom edge 20 is gusseted along contour 30 to provide a self-standing feature.
Alternatively, the pouch could be formed from a single folded sheet bonded at its overlapping edges, and a contoured gusseted insert. Similarly, although the spout 34 is preferably opened by cut A--A at a 45-degree angle relative to the peripheral edge 18, this angular relation is not critical.

For example, the preferred pouch 10 includes sheet walls 12 which are bonded together at their peripheral edges 14-20 to define an inner chamber. A bottom edge 20 is gusseted along contour 30 to provide a self-standing feature.
Alternatively, the pouch could be formed from a single folded sheet bonded at its overlapping edges, and a contoured gusseted insert. Similarly, although the spout 34 is preferably opened by cut A--A at a 45-degree angle relative to the peripheral edge 18, this angular relation is not critical.
