Description

FIELD

The technology described herein relates a flexible pouch for use in holding drink components that may be used in a drink-making machine in order to make a drink, like a cocktail.

BACKGROUND

A variety of pouches are known for holding liquids, such as drink pouches or alcohol pouches. Pouch types include flat pouches and standup pouches, among other pouches. Flat pouches may be formed by sealing together two layers of material around an outer edge of the pouch to form an internal compartment. Flat pouches may also be made from an extruded tube, or by other methods. Flat pouches typically do not stand up on their own. They are stored in a container, such as a cardboard box. Standup pouches include a front and back layer, as well as a bottom layer. Standup pouches typically will stand up on their own.

SUMMARY

An example flexible pouch is shown and described for holding a liquid component.

DETAILED DESCRIPTION

The technology described herein relates generally to a pouch 10 for use in storing a liquid, such as a concentrate, a non-concentrate, a flavor, an alcoholic beverage, another beverage component, or the like. The pouch 10 is designed for use in a drink machine (not shown) that incorporates a cutting blade (not shown) that slices the pouch longitudinally in order to open the pouch. The pouch 10 could alternatively be used without a drink machine and could be opened by hand by tearing or cutting through part of the pouch 10, as will be described in greater detail below.
An example pouch 10 is shown in FIGS. 1-5. The pouch 10 is a flexible pouch that has an inner compartment 12 and an outer, sealed edge that forms a rim 14. The pouch 10 is formed from a front layer 16 and a back layer 18. As discussed in greater detail below, the front and back layers 16, 18 may be formed from two separate sheets, or from a single sheet of material that is folded over or shaped as a tube. The front layer 16 has an inner and an outer surface and the back layer has an inner and an outer surface. A space is provided in the compartment 12 between the inner surfaces of the front and back layers. The compartment 12 forms a space for accommodating a liquid for storage therein. The perimeter of the pouch 10 is sealed entirely around the outer perimeter. The sealing process is known in the art and creates a seam or rim 14. The pouch 10 may be hermetically sealed.
The general shape of the pouch 10 is rectangular with a spout 20 at an upper end. The pouch 10 has a longitudinal axis Y-Y that extends along the long axis of the pouch 10. The pouch 10 also has a transverse axis X-X that is perpendicular to the longitudinal axis Y-Y. During use, the longitudinal axis Y-Y of the pouch 10 will be positioned substantially vertically. The pouch 10 has a front outer surface 22 and a rear outer surface 24. The shape of the front outer surface 22 matches the shape of the rear outer surface 24. The perimeter of the pouch 10 is cut simultaneously after the pouch 10 is sealed in order to form matching front and rear outer surfaces 22, 24.
The compartment 12 has a top end 26, a bottom edge 28, a left and right side edge 30, 32, which are substantially identical to one another, and a front and rear surface 22, 24, which are also substantially identical to one another in shape. A narrowed portion 34 is positioned at the top end 26 of the compartment 12, and the bottom edge of the compartment is flat 28. An upper edge 36 of the compartment 12 is substantially an inverted V-shape, with the upper edge 36 formed in two parts that extend from the left and right side edges 30, 32 to the narrowed portion 34 on either side of the pouch 10. The compartment 12 has a length L1 that is greater than a width W1 thereof, although the length could be less than the width, if desired.
The rim 14 of the pouch 10 is formed from the front and back layers 16, 18, which are joined together around the outer edge by heat sealing or otherwise. The rim 14 has a top end 38, a bottom edge 40, a left and a right side 42, 44, which are substantially identical to one another, and a front and a back surface 22, 24, which are substantially identical to one another in shape, but may have different graphics applied thereto. The top end 38 of the rim 14 includes a spout 46 into which the narrowed portion 34 of the compartment 12 extends. The spout 46 is approximately rectangular in profile, but could have other shapes. The bottom edge 40 of the rim 14 has an inwardly curved or concave surface. The spout has a top edge 38 and the top edge 38 of the spout 46 has a curved surface, which may have a convex shape. The bottom concave shape and the top convex shape may be complementary to one another, such they are substantially identical or created by the same cutting tool, such as a die punch. Other shapes could also be used for the top edge 38 of the spout 46. The side edges 42, 44 of the rim 14 are straight, but could be other shapes. The rim 14 also includes an upper edge 50 that is an inverted V-shape that mirrors the upper edge 36 of the compartment 12. The upper edge 50 of the rim 14 mates with the spout 46, which is centrally located. The side edges 42, 44 of the rim 14 join with the upper edges 50 of the pouch 10 at shoulders 52, which are rounded portions where the side edges 42, 44 meet the upper edges 50 of the rim 14.
The spout 46 includes two necked-in cut outs 54, one on each side of the pouch 10, that are positioned between the spout 46 and the adjacent upper edge 50 of the pouch 10. These necked-in cut outs 54 help to create a narrowed portion 34 of the spout 46 that can be used for tearing the spout 46 open by hand.
The pouch 10 also includes a notch 56 that extends downwardly and inwardly at the top edge 38 of the spout 46. This notch 56 is used to create a thinned portion 58 of the spout 46 to aid in cutting the pouch 10 with a blade (not shown) that is positioned inside a drink machine. It is contemplated that a cutting blade will enter the front or rear surfaces 22, 24 of the pouch 10 and slice downwardly longitudinally Y-Y. The notch 56 is designed to aid in the guiding of a blade through the spout 46 of the pouch 10 in order to release the contents of the pouch 10 therefrom. In practice, the top end 38 of the pouch 10 will be inserted into a receptacle in a drink machine such that the top end 38 faces downwardly and the bottom edge 40 faces upwardly. A blade will enter from the front or rear surfaces of the pouch 10 and slice the pouch 10 vertically through the front and/or rear surfaces 22, 24 of the pouch 10 and spout 46. The blade is directed towards the notch 56 in the pouch 10 since that area of the pouch 10 has a thinner rim 14. Thus, the notch 56 helps to promote cutting in a desired location of the pouch 10.
The pouch 10 dimensions are, in part, determined based upon the types of manufacturing machines presently readily available. As other manufacturing machines become available, the pouch 10 size and shape may vary. In addition, although the compartment 12 mimics the shape of the rim 14 of the pouch 10 (with the exception of the bottom edge 40), the compartment 12 could have a shape that is different from that of the rim 14.
The notch 56 on the top end 38 of the pouch 10 can be formed with an angle Al of about 90 degrees. The notch 56 could have other dimensions than shown and described. The necked in cut outs 54 that form the tear location in the spout 46 could be formed at an angle A2 of about 50 or 60 degrees. The cut outs 54 could have different dimensions than shown and described. The cut outs 54 of the spout 46 form a thinner area 58 of the rim 14, making it easier to remove the spout 46 from the remainder of the pouch 10 by tearing or cutting. The indented notch 56 on the top edge 38 of the pouch 10 also defines a thinned portion 58 at the top end of the pouch 10 for cutting, as previously discussed.
The compartment 12 has a thickness that can vary based upon how much contents are required in each pouch 10. One exemplary thickness is about 11 mm. A length L1 of the pouch 10 may be about 139 mm while a width W1 may be about 82 mm. The width W2 of the spout 46 may be about 35 mm and the width of the narrowed portion 34 of the compartment 12 may be about 20 mm. The width W3 of the narrowed portion 34 of the spout 46 may be about 25 mm. The concavity of the top edge 38 and convex surface 40 at the bottom end of the pouch 10 may be about R70. The angle of the top shoulders 52 of the pouch 10 relative to the transverse axis X-X may be around 15 degrees. The thickness of the rim 14 at the narrowest point at the bottom edge 40 may be about 5 mm. The shoulders 52 may have a radius of about R12.
FIG. 6 depicts an example of the layout used during manufacture of the pouches 10 according to the invention in the production line. As shown, the curved radius of the top end 38 and bottom edge 40 of the pouches 10 helps to provide greater efficiency for the manufacture of the pouches 10 since more pouches 10 can be made from a sheet of material. The concave top edge 38 of the pouch 10 is cut at the same time that the convex bottom edge 40 of the preceding pouch 10 is cut. Part of the spout 46 of each pouch 10 is formed within the bottom end of each preceding pouch 10. Because of the curved shape of the pouch 10 at the top and bottom ends, the number of pouches 10 made from a sheet of material is increased, saving cost and time. In particular, the repeating length RL of the cut is less than the length L2 of the actual pouch that is formed. In addition, the curved cut at the bottom edge 40 may be created by a curved compound blade 64, an example of which is shown in FIG. 7. The lifetime of a curved blade is longer than that of a straight blade. Thus, the curved blade will last longer and will need less maintenance than a straight blade. It also helps to provide a unique look to the pouch 10.
During production, the distance between the top 38 of each pouch 10 and the shoulder 52 of each pouch 10 is about 27 mm. The distance between the bottom 28 of the compartment 12 of each pouch 10 and the shoulder 52 of the following pouch 10 is about 32 mm. The repeating length RL of the pouch 10 is about 129 mm, which is smaller than the actual length L2 of the pouch 10, which is about 139 mm. The reason for this is because the top of each pouch 10 is recessed into the bottom of the preceding pouch 10. Thus, approximately 10 mm of material can be saved per pouch 10 by utilizing the curved bottom edge 40 and curved top edge 38. The cutting blade may be formed as a shaped (non-straight) blade that serves as a cookie cutter for cutting the bottom of one pouch 10 at the same time that it cuts the top of the next pouch 10. One type of cutting tool that can perform this type of cutting is a die punch set 62. An example shaped cutting blade 64 is shown in FIG. 7. Alternatively or in addition thereto, multiple cuts can be made to form the various shapes of the pouch 10, if desired.
The pouches 10 are cut apart using standard cutting machines and cutting units 62, such as shown in FIGS. 8-9. Types of blades that may be used include steel, high speed steel, die steel, tungsten carbide, Teflon coated materials, and other metal or plastic blades. The blades may be heat treated and hardened. The blades are long-lasting and provide razor-sharp cutting. Any type of cutting blade may be used in order to make the cuts necessary to create the pouch 10 shape.
The pouch 10 may be made of any known material for storing beverages. The material may be food grade or non-food grade, depending upon what is stored in the pouch 10. For example, motor oil would not need food grade materials while orange juice would need food grade materials.
One type of material that is contemplated is a multilayer material that includes a barrier. This multilayer material utilizes a combination of polyester (PET), foil, and polyethylene (PE). Multilayer materials will typically include an outer layer that can accept graphics, a barrier layer, and a sealant layer, among other layers. Types of outer layers that are contemplated either alone or in combination with other materials include polypropylene (PP), polyethylene (PE), polyester (PET), and nylon. Barrier layers may be foil, metalized poly, ethylene vinyl alcohol (EVOH), or silicon oxide, among other materials and combinations thereof. Sealant layers may be PE or PP, among other know sealant layers. The combinations may be formed by lamination, or other means. One type of pouch 10 may be a laminated foil. Although not shown, the pouches 10 could alternatively be paper based or a combination of paper and plastic. The pouches 10 could be 3 or 4 layer laminates, such as 3 or 4 film layers like Paper/Poly/Foil/Poly. Alternatively, the pouches 10 could be similar to aseptic brick packages, or aseptic bags, but formed at least in part in the manner shown. The pouches 10 can be made from a heat-sealable, heat-weldable, or ultrasonic sealing flexible laminate, such as aluminum sheet covered with a plastic material, or from any other suitable material. It is contemplated that the front and back sheets of material are made of the same material, although it's possible that they could be made of different types of material. For example, if it's preferred that the front surface be transparent while the back surface is opaque, the materials may be different. The pouches 10 could be formed so that graphics are provided on only one of the sheets of material, on both a front and rear surface of the sheet, with the front sheet being transparent.
While the rim 14 is shown as being continuous in the figures, it could be discontinuous as long as the compartment 12 is sealable. The rim 14 can be formed by joining the front and back sheets of material using heat sealing, heat welding, ultrasonic sealing, or other known manufacturing methods. Alternatively, adhesives, crimping or other suitable methods can be used to bond the sheets together around the perimeter. Also, as discussed above, a single extruded tube can be used in place of two sheets. When a tube is used, only the ends of the pouch 10 need to be sealed since the sides of the tube are already sealed. However, in order to provide a uniform appearance, the entire outer edge of the pouch 10 may be sealed to form a rim 14.
In an alternative embodiment, a single sheet of material can be used that is folded over on itself, with the free ends being bonded together to define the sealed compartment 12. In this embodiment, the folded over side may remain unsealed, or the entire outer edge of the pouch 10 may be sealed to form a rim 14 in order to provide an overall uniform appearance to the pouch 10. The compartment 12 in each of these embodiments is sealed fluid tight.
The rim 14 that is created by heat sealing or otherwise can be a thin line or combination of lines, a patterned section, or a smooth wide rib-like section. The rib 14 may have a thickness that ranges from about 5 mm to 12 mm. A preferred range is 6 mm to 10 mm. An example thickness is about 6 mm.
When the pouch 10 is empty, the compartment 12 is substantially flat. When the compartment 12 is filled with a liquid, the compartment 12 bulges outwardly on both the front and rear sides 22, 24. The pouch 10, as shown, is symmetrical. It is envisioned that a pouch 10 could be non-symmetrical and still incorporate the novel features of the present invention. Moreover, pouches 10 of different shapes and sizes could incorporate features taught in the present disclosure.
The pouches 10 may be used to hold a fluid, a liquid, a beverage, pasty media, fine granular material, or other flowable material, including thicker materials. The pouches 10 may also be used to hold non-liquid materials, if desired. It is contemplated that the pouch 10 will be used as a beverage container.
According to one embodiment of the invention, a flexible pouch 10 for holding a fluid includes a front and a rear side 16, 18, a rim 14, and a spout 46. The front and rear sides 16, 18 together define a compartment 12 for holding a fluid. The compartment 12 has a longitudinal axis Y-Y that extends through the long axis of the compartment 12 and a transverse axis X-X that is perpendicular to the longitudinal axis Y-Y. The rim 14 is positioned around the compartment 12 and is formed by coupling the front and rear sides 16, 18 together. The spout 46 is positioned at the top end 38 of the pouch 10. The spout 46 has a notch 56 at the top end thereof. The spout 46 has a convex shape at a top cut edge 38 thereof. The rim 14 includes a bottom cut edge 40 that has a continuously concave shape from one side 42 of the pouch 10 to the other side 44 of the pouch 10.
