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.

  • user contact surface 16 generally corresponds to the portion of the mouthpiece 12 which the user may take into his/her mouth when drinking from the container.
  • mouthpiece 12 is shown in position A which corresponds to a closed and unused position. That is, position A indicates to a potential user that the container has not been previously opened. Furthermore, the mouthpiece is closed to prevent access to the fluid contents of the container. In position B, the mouthpiece is open for fluid communication with the contents of the container. Movement from position A to position B may also correspond to destruction of an interior seal (see for example FIG. 18 ) to allow access to the fluid contents. In some instances, the mouthpiece 12 may be provided with features to prevent mouthpiece 12 from returning to position A. Mouthpiece 12 may be further displaced from position B to position C to re-close the container, to prevent access to the fluid contents. In position C, the position of the mouthpiece 12 indicates to the user that the container has been previously opened.
