Definitions

• the invention relates to disposable fluid containers including leak-proof bags made from flexible film, beverage container boxes lined with leak proof film, containers made with metalized films and other containers for edible fluids.
• Containers for edible fluids include containers for drinks, edible pastes, condiments, sauces, toppings and the like. These disposable containers also include single serving size items which may be consumed as single drink servings. Other disposable containers may be sized to provide multiple servings. In some instances, the containers may be resealed by the user for later use.
• the pre-wrapped drinking tubes often become separated from their corresponding containers and the user is left without a straw.
• the user must either find a replacement straw (which may be particularly inconvenient) or the user may be forced to tear open the container to drink directly from the container.
• straws or other drinking tubes are provided so that the user may drink from the container while maintaining the container in a generally vertical orientation.
• the user must be careful to avoid misalignment of the interior portion of the drinking tube from the liquid contents of the container. If the interior portion of the drinking tube is moved, or inserted to an insufficient depth, the user may not be able to extract the remaining fluid contents of the container.
• a drinking tube which has been used to pierce the seal of the container may experience some leakage of the fluid between the pierced seal and the drinking tube, when the container is tipped away from the desired vertical orientation.
• a disposable container for an edible fluid defines a top edge and a bottom edge.
• the container includes a side wall which extends between the top edge and the bottom edge.
• the container also includes a chamber for storing the fluid up to a defined level. The defined level is positioned between the top edge and the bottom edge of the container.
• the container also includes a channel for fluid communication between the bottom edge and an opening adjacent to top edge.
• the channel is defined by a layer of a flexible film which extends vertically. The channel is positioned adjacent the side wall.
• the exterior of the container may be rigid or flexible.
• rigid box type containers are typically lined with leak proof flexible liners.
• the container may be made from a combination of flexible and rigid materials.
• the channel may be positioned adjacent any side wall of the container. The channel extends vertically adjacent that side wall so that the channel will enable fluid communication between the bottom of the container and the location adjacent to the top edge of the container.
• a seal may be provided to close the opening.
• the seal may be removable or destructible.
• an optional cover may be provided to protect an area surrounding the opening so that the user contact surface may be kept clean during shipping and handling.
• the layer of flexible film forming the channel may be secured to the side wall.
• the layer of flexible film may be made from a sheet which itself defines the side wall.
• the channel defined by the layer of flexible film may be located either inside or outside of the chamber.
• the opening may be located at or near the top edge.
• an optional spout is provided for selective fluid communication with the contents of the container.
• the spout may operate between a first position and a second position. In the first position, the spout is unused and closed against fluid communication with the chamber. In the second position, the spout is open for fluid communication with the chamber. In the second position, the user may drink or dispense fluid from the interior of the container.
• the spout may also be designed to operate between the first position, the second position and an optional third position. In the third position, the spout is closed against fluid communication with the chamber. However, when the spout is in the third position, the user is alerted that the container has been opened. In some embodiments, it may be desirable to prevent the spout from returning to the first position.
• the invention in another embodiment, includes a spout for use in a disposable container designed for use with edible fluids.
• the container defines a chamber to contain the edible fluid.
• the spout operates from a first position in which the spout is unused and closed against fluid communication with the chamber.
• the spout moves from the first position toward the second position in which the spout is open for fluid communication with the chamber.
• the spout is also capable of moving to a third position in which the spout is closed against fluid communication with the chamber.
• the user is warned that the spout has been opened and moved from the first position. In some embodiments, it will be desirable to prevent the spout from returning to the first position after initial use.
• the spout may be designed to destroy a seal which prevents fluid communication between the chamber and the exterior of the container.
• the seal may be destroyed by the spout when the spout moves from the first position to the second position.
• the spout may contain a movable projection which pierces the seal when the spout is moved from the first position to the second position. If desired, the spout may be biased for one way movement from the first position to the second position.
• the spout defines a dispensing tip.
• the dispensing tip defines a mouthpiece. The mouthpiece may be used as a drinking tube which allows the user to drink fluid from within the container.
• the container may be adapted so that it is reusable.
• the container may be resealable.
• the container may be adapted so that it may be refilled with the same edible fluid or another edible fluid, as desired by the user.

• This embodiment provides one example of the many different types and configurations of mouthpieces which may be used to achieve similar results.
• FIGs 13, 14 and 15 illustrate the container 10 as shown in Figure 10, in which the mouthpiece is shown in the first position A.
• First position A corresponds to a position in which the mouthpiece is closed and also indicating that the mouthpiece has not been previously opened.
• mouthpiece 12 comprises two major components, a dispensing tip 38 which connects with and rotates relative to a base member 28. In position A, dispensing tip 38 is spaced apart from base rim 29, forming a gap G.
• Base 28 is securely affixed to first wall 22 of the container 10.
• Mouthpiece 12 is positioned between bottom edge 20 and top edge 18. More specifically, in this example, mouthpiece 12 is positioned adjacent upper edge 18.
• Base 28 is securely attached to first wall 22 of the container 10.

• dispensing tip 38 When mouthpiece 12 is in position A, dispensing tip 38 is pointed inwardly toward the body of the container. In that position, cutter 40 is positioned outwardly from the thin film defining first wall 22. Seal 24 remains intact over opening 23 to prevent outward flow through channel 26. Fluid within the chamber 2 of the container 10 is in fluid communication with the channel 26 via fluid entrance 30. However, when the mouthpiece 12 is in position A, opening 13 is sealed and there is no fluid communication between the chamber of the container 10 and the exterior of mouthpiece 12.
• base 28 has a hollow core 32 which is capable of fluid communication with a first conduit segment 34. However, in position A, first conduit segment 34 is not aligned with second conduit segment 36. Consequently, fluid communication is not possible between the base and dispensing tip.
• FIGs 16, 17 and 18 illustrate mouthpiece 12 when it is open for fluid communication in position B.
• Dispensing tip 38 points outwardly to position B.
• dispensing tip 38 extends above upper edge 18 of the container for convenience.

• the hollow core 32 of base 28 is in fluid communication with first conduit segment 34.
• First conduit segment 34 is aligned for fluid communication with second conduit segment 36, thereby providing for fluid communication between the contents of the container, the mouthpiece, and the exterior thereof.
• an internal threaded arrangement may be provided between base 28 and dispensing tip 38. By rotating dispensing tip 38 from position A to position B, dispensing tip 38 advances toward base 28 and into destructive contact with seal 24.

• dispensing tip 38 is shown in position C such that mouthpiece 12 does not provide fluid communication between the contents of the container and the exterior thereof. Specifically, in this position, first conduit segment 34 is no longer aligned with section conduit segment 36. Accordingly, in position C, mouthpiece 12 is sealed against fluid communication between the contents of the container and the outside thereof.
• Figures 22 to 27 illustrate the disassembled components of one example of the mouthpiece described herein.

• the connective bridge at surface 96 will break away during movement from the first position toward the second position, and the cutter 90 will be free to move outwardly.
• the drinking tube 61 is shown in a drinking position corresponding to the second position of the spout.
• the lugs 67 are detached to the edge 62 of the mouthpiece 60.
• the lugs 67 were broken when the mouthpiece 60 was rotated clockwise from the first position to the second position.
• FIG 29b the cutter is shown inside the inner race, in their original molded position.
• the cutter 90 is shown as it is attached to the inner race 75 after molding.
• Arcuate ramp 92 defines a ramp that works with the leg 103 provided within the mouthpiece 60.
• the emboss 105 (shown in Figure 30a) on the mouthpiece 60 is provided to travel in groove 84 defined along the top of the inner race 75.
• the stopper 85 is part of the inner race 75 and is provided to limit the range of travel of the mouthpiece 60 from its start position to a maximum of 270 degrees.
• Figure 30a shows a bottom view, in perspective, of the mouthpiece 60.
• the sectional views in Figures 33a and 34a show the interior features of the assembled spout.
• main post 107 serves to guide the cutter 90 and provide a structure supporting the legs 103 which will be contacting and exerting pressure against the ramp 92 of the inner race 75.
• Groove 108 defined along the interior surface of the mouthpiece 60, is snap-fit over the ring 79 of the inner race 75. Opening 106 defines a fluid entrance for the fluid to flow into the drinking tube 61.
• the inside diameter of the mouthpiece 60 is slide-fit against the outside surface of wall 76 of the inner race 75.
• the interior configuration of the mouthpiece 60 prevents the liquid from flowing out from the container unless the mouthpiece 60 is moved into the second position (i.e., the open position) in which the two openings 106 defined by the mouthpiece 60 and opening 80 defined by the inner race 75 are properly aligned to allow such flow.
• Emboss 105 is situated within the mouthpiece 60, at the top of the interior surface of the housing 64. Emboss 105 engages and travels within groove 84 of the inner race 75. Emboss 105 also acts as a stopper or travel limiter against the edge of the stopper 85 of the inner race 75. Bottom surface 101 of the tamper proof ring 65 is flush with bottom surface 102 of the mouthpiece 60. In a preferred embodiment, both of the surfaces 101 and 102 may be welded, glued, or otherwise secured to the exterior surface of the container. For example, suitable materials may be selected to permit the parts and container to be ultrasonically welded or bonded. Similarly, suitable adhesives may be chosen to bond parts made of appropriate materials, which in many instances will be plastics.
• the adhesives should be of sufficient strength and exhibit minimal elasticity, so that when force is exerted against the cutter, there will be no de-lamination of the adhesive and no consequent loss in the cutting/piercing force to be exerted by the cutter against the wall of the container.
• Figure 30b shows a top view of the inner race 75 in which lug 93 is attached at the bottom of the inner race 75, in recess 81.
• Figures 31a and 31b show top and bottom views of the cutter 90 in perspective.
• the outer surface of the cutter 90 is flush with the outer surface of a first tooth 97 located at one end of a row of teeth, whereas teeth 91 are recessed away from the outside surface of the cutter 90.
• Recess 98 is not provided with any teeth.
• the first tooth 97 is configured such that its front surface (leading edge) is rounded.
• the row of teeth is configured in this manner so that when the cutter 90 pierces linearly through the wall of the container, the row of teeth will initially make an indent in the wall of the container.
• a flap 125 corresponding to a portion of the wall of the container is severed in the area of the recessed teeth 91.
• tooth 97 defines a greater cutting radius relative to the teeth 91.
• tooth 97 will plow and push open the flap of film, leaving a partially uncut segment attached to the wall of the container, thus forming the flap 125.
• This partial uncut segment will hold the flap 125 and prevent the cutout portion of the wall (i.e., the flap) from entering the mouthpiece 60 or clogging opening 106 of the mouthpiece.
• the ramp 92 there is a surface 94 against which the legs 103 of the mouthpiece 60 engage to exert a force against the cutter 90, to rotate the cutter.
• the surface 95 of the cutter 90 is engaged against surface 86 of the stopper 82 positioned on the interior surface of the inner race 75 (shown in Figure 32a).
• the cutter 90 is prevented from rotating until the top of lug 93 has linearly passed under the edge 87. After the top of lug 93 clears edge 87, the cutter is rotated.
• FIG. 33a is a sectional view of the spout shown in Figure 33b, showing the interior of assembled spout.
• the lugs 67 after they are broken from the mouthpiece, exert a force against the outside of edge 62, which in turn maintains a force to prevent removal of the mouthpiece 60 from the inner race 75.
• Figure 33b is a top view of the assembled spout.
• Stopper 66 and 66' are positioned adjacent stoppers 63 and 63' of the mouthpiece 60.
• the mouthpiece 60 is shown in the first position.
• the lugs 67 are broken when the mouthpiece is turned clockwise toward the second position, to open the sealed container.
• the stoppers 63 and 63' 180 degrees, the stoppers 63, 63' will slide over stoppers 66, 66', pushing the tamper proof ring 65 outwardly and allowing the stoppers 63, 63' and 66, 66' to pass.
• the stoppers pass as shown in Fig 34b, the mouthpiece has rotated 180 degrees, and the spout is now in the drinking position.
• the acute inner angles of stopper 63, 63' now face the adjacent stoppers 66', 66, the acute angles of the stoppers 63, 63' prevent the counterclockwise rotation of the mouthpiece 60 from the second position toward the first position.
• Figure 34a shows a sectional view of the assembled spout of Figure 34b in the open, drinking position (the second position) after the cutter has traveled linearly toward the container and pierced the wall of the container.
• Ramp 92 is engaged with leg 103 of the mouthpiece and the centre post 107 guides the travel of the cutter 90.
• Figure 34a also shows groove 84 which defines a path for travel of emboss 105 (shown in Figure 30a).
• Figures 35a and 35b show side and bottom views of the mouthpiece when the container is sealed and unopened, and the spout is in the first position.
• the surfaces 88 and 69 of the inner race 75 and the tamper proof ring 65 are secured to the wall 120 of the container.
• the cutter is positioned within the inner race 75, and in turn, within the housing 64 of the mouthpiece 60.
• Figures 36a and 36b show side and bottom views respectively of the mouthpiece 60 after the mouthpiece has been rotated 180 degrees in a clockwise direction, from the first position to the second position.
• Area 98 of the cutter is shown, where there are no teeth, which also corresponds to the area 130 where the wall of the container will not be cut by the first tooth 97, but merely indented and stretched.
• Opening 106 in drinking tube 61 is in fluid communication with the opening 80 of the inner race 75.
• the cutter 90 has traveled linearly toward the container, piercing the wall 120 of the container leaving a flare 122 in the wall 120 of the container.
• Figures 37a and 37b show side and bottom views of the mouthpiece rotated to 270 degrees bringing the mouthpiece to a third position where the spout is closed against fluid flow.
• the cutter 90 has traveled by rotation and has made a cutout in an arc along the wall (equal to about three-quarters of a circle) leaving the area 130 uncut.
• the tooth 97 is shown at the extent of its travel, to one end of the segment 130.
• the area without teeth 98 is positioned to the right of the assembled spout, whereas in Fig 36b this area 98 without teeth, is positioned at the lower edge of the assembled spout.
• the area 130 corresponds to the uncut zone where the flap 125 remains connected to the wall 120 of the container.
• the first tooth 97 and a recessed tooth of the cutter 90 are shown when the spout is in the third position.
