DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring in detail to the drawings and with particular reference to FIG. 1, a flexible pouch 10 is shown. This flexible pouch can be made from a heat-sealable, heat-weldable or ultrasonic sealing flexible laminate such as an aluminum sheet covered with a plastic material or from any other suitable material. The pouch 10 can be filled with liquids such as beverages, liquid, pasty media, fine granular material or any other suitable objects. It is contemplated that the flexible pouch will primarily be used as a beverage container.

As seen in FIGS. 1 and 2, this flexible pouch 10 generally has a figure eight shape. The flexible pouch is made from a first sheet 12 and a second sheet 14. In FIG. 1, the first sheet 12 is in front of the second sheet 14. The shape of the first sheet 12 matches the second sheet 14 except at the uppermost edge thereof as will be explained in detail below. The two sheets 12 and 14 are sealed together around their periphery to form a compartment 16. The compartment 16 is formed between the first and second sheets 12 and 14 and will hold the contents of the flexible pouch 10. For example, a beverage can be placed within the compartment 16.

A seam 18, alternatively referred to as a side seal, extends along the sides of the first and second sheets 12 and 14. While this seam is shown as being continuous in the figures, it should be appreciated that it could be discontinuous as long as a sealed compartment 16 was provided. This seam 18 can be formed by heat-sealing, heat-welding or ultrasonic sealing the two sheets 12 and 14 together. Otherwise, adhesives, crimping or any other suitable arrangement could be used in order to bond these sheets together. Also, a single extruded tube can be used in place of the two sheets. Alternatively, a single sheet can be folded over on itself and can have its free ends bonded together to thereby define a portion of the sealed compartment 16. It is merely necessary that an appropriate sealed compartment 12 be provided. It is contemplated that this compartment 16 will be fluid tightly sealed.

A first edge 20 of the first sheet 12 and a first edge 22 of the second sheet 14 are provided on the left-hand side of the pouch 10 as seen in FIG. 1. The seam 18 extends along these first edges 20, 22. In addition, a second edge 24 on the first sheet 12 and a second edge 26 on the second sheet 14 are provided along the right-hand side of the flexible pouch 10. The edges 22, 26 of the second sheet 14 are behind the first edges 20, 24, respectively, of the first sheet 12. The edges 20, 22 and the edges 24, 26 conform such that the shape of the first and second sheets 12, 14 along the sides of the pouch 10 are uniform. As previously noted, the first edges 20, 22 are sealed together and the second edges 24, 26 are sealed together.

At the top of flexible pouch 10, a frangible element or membrane 28 is provided. This element or membrane 28 is partially shown in FIG. 1 because a portion of the first sheet 12 has been removed. Referring to FIG. 4, the frangible element or membrane 28 is better shown. This FIG. 4 is a side view between the first and second sheets 12, 14 taken along line IV--IV of FIG. 3. As can be seen in FIG. 4, the frangible element or membrane 28 includes a flexible first gusset provided at the end of the pouch. When the pouch 10 is standing upright, this end will be the top of the pouch. This gusset generally has a V-shape. Two walls 30, 32 are provided on the one-piece gusset. These walls 30, 32 converge to form the V-shape in side sectional view.

In particular, it is contemplated that the flexible first gusset forming the frangible element or membrane 28 is a single sheet which has been folded to form a crease 34. This crease 34 is generally linear and extends to the outermost edges 36, 38 of the first and second sheets 12, 14 as indicated in FIG. 3. This crease length is achieved because the first gusset has the same length and shape as the sheets 12, 14 at the top of the flexible pouch 10. Of course, any other suitable configuration could be had for the gusset. In other words, the frangible element or membrane 28 could be formed from a flexible gusset which does not extend completely to the outermost edges 36, 38 of the sheets or which extends beyond these edges. While it is contemplated that the contour of the outer edges of the frangible element or membrane 28 will match the contour of the uppermost portion of the pouch 10, other designs for the frangible element or membrane 28 are possible. Also, instead of using a single gusset which is folded to form crease 34, two separate membranes could be welded or otherwise adhered to one another to form a crease along the joint between them.

Two seams 40, 42 are provided at the upper end of the pouch 10. The wall 30 of the frangible element or membrane 28 is heat-sealed or heat welded or otherwise sealed to the second sheet 14 at seam 40. This frangible element or membrane 28 is also adhered at its wall 32 to the first sheet 12 along seam 42. It should be noted that seam 40 is longer than seam 42. Therefore, the frangible element or membrane 28 is not completely symmetrical about the crease 30. Moreover, the rear or second sheet 14 is slightly longer than the first sheet 12. As seen in FIG. 3, this seam 40 provides an exposed area which a user can grip in order to hold the pouch. Such an arrangement can be useful when attempting to insert a straw 44 into the wide mouth pouch 10 as will be described below. Of course, the instant invention will work regardless of where it is held by the user. In other words, it is not necessary for the user to grasp this seam 40 in order to insert the straw 44 into the pouch 10. It is therefore possible for the lengths of the first sheet 12 and second sheet 14 to be the same. In such a modified arrangement, the uppermost edges of seams 40 and 42 would be aligned. In such a modified arrangement or in the arrangement shown in the drawings, it should be noted that the top of the pouch between the first and second edges 22, 26 of the second sheet 14 is generally flat. It is contemplated that when the pouch 10 is filled and standing upright, the upper edge 46 will be horizontal. As will be described below, the gusset of the frangible element or membrane 28 will define a pocket 52. At least when the pocket is closed, the upper edge 48 of the first sheet 12 will also be flat and generally horizontal when the pouch is standing upright.

The frangible element or membrane 28 is made from a readily rupturable material such as a flexible laminate. A straw 44 can be inserted into the access area formed between the walls 30, 32 of the frangible element or membrane 28. Then a small portion of the crease 34 will be pierced by the straw to form an opening 50 to the compartment 16. It should be noted that the diameter of the straw 44 is relatively small compared to the length of the crease 34. In other words, the length of the frangible element or membrane 28 is considerably greater than that of the diameter of the straw 44. Only a small drink opening 50 is punctured in the pouch 10. It is not contemplated that the entire seam or crease 34 will be ruptured. In other words, the opening 50 extends over a portion of the gusset but is out of contact with the first and second sides of the pouch 10 at seams 18. However, the entire length of the crease 34 could be ruptured if so desired.

Within the areas between the first and second sheets 12, 14 at the top of the pouch, the above-noted pocket 52 is formed. This pocket 52 has a wide mouth or opening which can easily accommodate insertion of the straw 44. A portion of the first and second sheets 12, 14 are movable toward and away from one another to define this pocket 52. The first and second edges 48, 46 of the sheets 12, 14 are sealed to the frangible element or membrane 28. The gusset of this frangible element or membrane 28 will be exposed when the first and second sheets 12, 14 are moved away from one another. It is not contemplated that the seams 18 at the sides of the sheets 12, 14 and gusset 28 will be ruptured. Rather, the sheets and gusset will be bowed in order to open the pocket 52. Of course, the seams 18 at the top of the pouch could be torn if the sheets 12, 14 were pulled sufficiently far apart. Because the frangible element or membrane 28 extends completely across the pouch to the outermost edges of the sheets 12, 14, such an opening of the sides of pocket 52 should not detrimentally effect the sealing of the pouch.

In other words, as seen in FIG. 3, the crease 34 of the frangible element or membrane 28 will extend completely between the outermost edges 36, 38 of the membrane. Therefore, closed sides of pocket 52 are formed by the edges of sheets 12, 14 and the edges of the membrane 28 all being welded or otherwise sealed along seam 18. As noted this seal between the side edges of the seams 40, 42 could be omitted. It is preferable, however, to extend these side seams 18 to the tops of the sheets 12 and 14 such that the pocket 52 is clearly defined.

Nonetheless, as noted above, it is contemplated that either and or both of the sheets 12, 14 will be bowed at their top portion in order to open the pocket 52 and insert the straw 44. Moreover, it should be noted that it is not necessary for the consumer to expressly open this pocket 52. Rather, insertion of the straw 44 will act to slightly wedge these sheets 12, 14 as well as the walls 30, 32 of the frangible element or membrane 28 apart in order to open the pocket. Accordingly, only a very slight opening of the pocket 52 can be carried out. On the other hand, the pocket 52 is sufficiently big such that a user could insert his or her fingers in order to more fully open the pocket before or during insertion of the straw 44.

As seen in FIG. 4, a majority of the frangible element or membrane 28 is contained between the first and second sheets 12, 14. A small portion of the rear wall 30 of the membrane 28 would extend above the top of the upper seam 42 of the first sheet 12. However, the uppermost edge of this wall 30 could terminate at or below the uppermost edge of the first sheet 12. In other words, it is now contemplated that the uppermost edges of the walls 30, 32 will extend to the uppermost edges of the seams 40, 42 to match the uppermost edges of the walls 12, 14. However, these uppermost edges of the walls 30, 32 of the membrane 28 could be terminated short of the uppermost edges of the walls 12, 14, if so desired.

When the frangible element or membrane 28 is unfolded, it will have a length which is shorter than that of the first and second sheets. For example, the rear wall could have a length of 1.19 inches whereas the overall length of the second wall 14 would be 6.50 inches. Likewise the length of the forward wall 32 could be 0.79 inches whereas the length of the first sheet 12 could be 6.1 inches. Therefore, there would be a total length of 1.98 inches for the frangible element or membrane 28 and this total length is considerable less than the 6.50 inch or 6.1 inch length of the second and first sheet 14, 12, respectively. These particular lengths are merely given as an example and it should be appreciated that the present pouch can be of any suitable size.

As previously noted, it is contemplated that the frangible element or membrane 28 will be a unitary one piece structure. Before the pocket 52 is opened or even when this pocket 52 is only slightly opened to accommodate a straw, the upper edges 46, 48 of the sheets 12, 14 will be generally parallel to the crease 34 formed by the folded frangible element or membrane 28.

As seen in FIG. 3, the innermost edges 54, 56 of the seams 18 terminate at the sides of the pocket 52. In other words, the edges of the first sheet 12, second sheet 14 and the frangible element or membrane 28 are all sealed such that the sides 52 of the pocket are closed. As previously noted, it is not contemplated that these sides will normally be ruptured during use of the pouch 10. Nonetheless, a wide mouth area is formed by pocket 52 for easy insertion of the straw 44. The distance between the edges 54, 56 at the upper side of the pouch 10 can be 1.88 inches, for example. Therefore, a relatively wide area is provided. This enables easy insertion of the straw. It is contemplated that the crease 34 will be pierced anywhere along its length between these edges 54, 56. It is not contemplated that the entire crease 34 would be ruptured although this is possible if so desired.

The sloping walls 30, 32 of the frangible element or membrane 28 will act to cam or guide an end 58 of the straw 44 towards the crease 34 as can be appreciated from FIG. 4. The opposed walls 30, 32 of the gusset forming the frangible element or membrane 28 act as a guide for the straw. As seen in FIG. 1, the end 58 of the straw 44 is tapered. This tapering can also aid in puncturing of the crease 34. However, a flat end similar to the upper end of the straw 44 could be used at end 58. Moreover, while a generally straight straw 44 is shown, it is contemplated that a flexible straw or any other known straw or other suitable opening device could be utilized with the pouch 10 of the present invention.

When using the present invention, the straw 44 will be inserted from the outside of the compartment 16. This straw 44 can be somehow bonded or otherwise attached to the exterior of the pouch 10 if so desired. Such a bonding should be easily rupturable so that the straw can be removed from the pouch 10 and inserted into the pocket 52 in order to pierce the frangible element or membrane 28. While it has been discussed that the straw will pierce a portion of the crease 34, any suitable portion of the frangible element or membrane 28 could be punctured. For example, it would be possible to form the frangible element or membrane 28 such that the crease would slope downwardly in a V-shape from sides 20, 22 to sides 24, 26, for example. Then, this arrangement would guide the straw to the central part of the pocket 52 relative to the two seams 18. Additionally, the frangible element or membrane 28 could be formed without a crease 34 such that any area of this membrane would be pierced by the straw 44. For example, a flat membrane could extend between the first and second sheets 12, 14. Any suitable portion of this membrane can be pierced.

However, due to the provision of the relatively large pocket 52, the straw is easily inserted into the pouch 10. It is unlikely that a user will pierce the front and back of the pouch 10 in the instant invention. Rather, it is likely that the frangible element or membrane 28 alone will be ruptured such that a suitable seal will be maintained for the pouch 10 except at this rupture area. This rupture or opening 50 will enable the contents of the pouch to be withdrawn. In other words, the beverage can be drunk from the pouch through straw 44. This limited opening arrangement will minimize or eliminate product spillage from the pouch 10. The pocket 52 will act as a reservoir which will contain any liquid which is expelled from the pouch from opening 50.

As indicated in FIG. 1, a second gusset 60 is provided at the bottom of pouch 10. This second gusset 60 is also a flexible element or membrane and can be made from the same material as the sheets 12, 14. A seam 62 will connect the second gusset 60 to the first and second sheets 12, 14. The first sheet 12, second sheet 14, first gusset of the frangible element or membrane 28 and second gusset 60 will define the compartment 16. When the pouch 10 is filled, it is contemplated that a majority of the second gusset 60 will generally be flat. In a folded unfilled state, the gusset will have a generally flat bottom portion 64. FIG. 3 indicates the connection of the fold line 68 for the second gusset 60 and its connection 64. When the pouch is filled, the second gusset 60 will unfold to have a flat bottom portion 64. Heat sinks 66 are provided at the second gusset 60. This sinks 66 are merely areas which are cut out of or omitted from the seal dies when forming pouch 10. Any suitable number or shape of heat sinks 66 can be used or they may be omitted altogether.

As seen in FIG. 4, the contents such as a beverage can be filled to level 70 within the compartment 16. If the pouch 10 is compressed, the level of the liquid 70 will rise above the crease 34. Alternatively, this content level 70 could always be above the crease 34 when the pouch 10 is initially filled. Either way, due to the provision of spaces 72, 74 within the compartment 16, a level of contents 70 can be above opening 50, if so desired.

Apart from the flexible pouch, a method for dispensing contents from a flexible pouch is disclosed by the present invention. In this method, the step of providing a compartment 16 within a flexible pouch 10 is provided. This compartment is initially sealed. Additionally, two sheets 12, 14 and a gusset of a frangible element or membrane 28 is provided. The two sheets 12, 14 and gusset 28 will form a portion of the compartment 16. The two sheets 12, 14 will have sealed edges 18 and the gusset of the frangible element or membrane 28 will be at a first end of the compartment 16. The method additionally includes the step of separating a portion of the first sheet 12 from a portion of the second sheet 14 adjacent the first end of the compartment 16 in order to expose the gusset 28. The compartment is maintained in a sealed state during the step of separating. The gusset of the frangible element or membrane 28 is then pierced by a straw 44. As previously noted, this step of inserting the straw 44 can actually cause the separation of the portions of the first and second sheets 12, 14. Then, the contents within the compartment 14 are removed through the opening 50 in the gusset.

Instead of using a straw 44, a suitable tool such as pin, funnel or nail, for example, could be used to pierce the frangible element or membrane 28. This tool would then be removed and the contents of the pouch 10 can be poured through the opening. However, it is contemplated that the pouch 10 will be normally be used as a beverage container and therefore a straw 44 will normally be used to discharge the contents.

When the opening 50 is formed, it is contemplated that this will be the only opening to the compartment 16. Of course, a plurality of openings could be provided in the frangible element.

With this pouch 10, a beverage or other contents from the compartment 16 can be easily dispensed. It is very easy to open the container and spillage of the product is minimized or eliminated. Inadvertent damage to the pouch 10 is avoided such as puncturing of both the front and rear walls when attempting to insert the straw. The flexible pouch can be easily manufactured and provides a secure arrangement for holding a product.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
