FIELD OF THE INVENTION This invention generally relates to a portable packaging system for transporting fluid, and more specifically to a beverage pouch or box with an integrated drinking straw.
BACKGROUND OF THE INVENTION Beverage containers, such as drink pouches or boxes, package beverages in a convenient and portable fashion. Various permutations of such devices are revealed in the prior art including U.S. Pat. No. 5,052,614 to Xuan, U.S. Pat. No. 5,425,583 to Wild, U.S. Pat. No. 5,833,368 to Kaufman, and U.S. Pat. No. 6,116,782 to Arkins. In order to access the contents of the package, a straw must be inserted into the package through a small, pre-defined location. These straws which are often affixed to the exterior of the container may be detached and lost, become soiled, or otherwise damaged rendering them unusable. Moreover, the user must apply sufficient force with the straw and at the correct orientation and location to puncture the packaging. Young children, in particular, may not have the strength or dexterity to properly position the straw to access the fluid within the package. Since the straws are used to puncture the container, they must have sufficient rigidity and sharpness for this task. These straws may cause injury if misdirected or mishandled.
There is also the potential for leakage and spillage if the opening created by the straw is larger than the diameter of the straw. With the necessary pressure applied to the pouch for straw insertion, upon entry, fluid may be forcibly expelled resulting in wastage and mess. If the straw is removed before the fluid contents are fully consumed, fluid may also inadvertently exit the perforation site.
In an effort to eliminate an externally attached straw, other flexible pouches with tear-off tops or free-floating straws have been described in the art as exemplified by Yeager in U.S. Pat. No. 5,937,617; Stefandl in U.S. Pat. No. 6,652,144 B2; and Murray in U.S. Pat. No. 6,854,490 B2. These all require dexterity and strength to open these packages as well as locate and manipulate the straws before the contents can be consumed.
In activities such as running or jogging, the current fluid pouches are inconvenient as it is difficult to manipulate a pouch and separate straw while in active motion. Wearable water bladders described by Forsman in U.S. Pat. No. 6,675,998 B2 and Skillern in U.S. Pat. No. 6,722,533 B2 and water bottles in a holster are not optimal given the weight of the device in addition to the fluid transported. Moreover, the jostling of the fluid within partially-filled containers can be distracting to the runner and their constant movement may result in chafing and discomfort.
SUMMARY OF THE INVENTION Accordingly, to the present invention advantageously provides better access the contents of the fluid container, such as a drink pouch, providing a more convenient, self-contained portable fluid delivery system.
In one aspect of the present invention, a straw is integrated into the pouch construction in order to provide a means of fluid egress. A segment of the straw internal to the pouch provides access to fluid within the pouch. This is continuous with an external straw segment that communicates the fluid to the recipient. The integrated straw eliminates the need for a separately affixed straw and manipulation of the straw to access the contents of the pouch. Since the straw is continuous with the pouch wall, no seepage or spillage of fluid can occur at this location.
Another aspect of the present invention is a closure method via one or more folds in the straw as it exits the pouch. These folds are secured in place with adhesive tape, glue, or the like. To access the contents of the pouch, the straw is straightened permitting the lumen occluded at the fold to become open and thus permitting fluid to exit the pouch. This provides a simpler and more reliable method of accessing the fluid within the pouch.
In another aspect of the present invention, evacuation of air from within the pouch eliminates fluid movement and jostling. The collapsible nature of the pouch sidewalls also decreases the possibility that air will reflux into the package.
In yet another aspect of the present invention, the pouch can be designed and shaped in various configurations to be most convenient and advantageous to the activity in which it is being used. The construction material is lightweight allowing for a maximal fluid-carrying capacity and minimal packaging weight.
Further aspects and advantages of my invention will become apparent from a consideration of the drawings and ensuing description.

DETAILED DESCRIPTION OF THE PREFRRED EMBODIMENTFIGS. 1 and 2 describe the preferred embodiment of this invention. The preferred type of fluid container is abeverage pouch100 comprised of two sheets of fluid-resistant film or sheeting that can be heat sealed at the edges to create a watertight barrier. The front103 and back104 walls of thepouch100 may be imprinted or decorated with various insignia or signage identifying the contents of thepouch100. The top101 may be fashioned to be thicker for ease of handling. Thepouch100 can be fashioned in different geometries such as rectangular, triangular, or circular. In one embodiment, thepouch100 may havepleats102 on the bottom permitting it to remain upright when placed on a table or other similar surface.Pouch100 is constructed in the same manner as a standard drink pouch, the construction of which is known to those of ordinary skill in the art.
Thepouch100 is formed of material of sufficient strength to resist puncture or breakage with normal carrying and handling activity. The pouch material is also compliant so that as the fluid is withdrawn, the pouch walls collapse and no dead space develops within the pouch.
Upon filling of the pouch, air may be evacuated from the pouch to reduce the jostling and movement of fluid within the container.
Pouch100 includes a straw that is integrated into thepouch100. Thestraw120 is composed ofcontiguous segments121,123, and124.Segment121 of thestraw120 is internal to thepouch100 and is of sufficient length to reach the bottom of the pouch so that all the fluid can be withdrawn from the container when held in an upright position. Theopen end126 of thestraw120 is where the user will withdraw the fluid contents.
At or near the top of thepouch100, thestraw120 exits thepouch100. This can be accomplished through anopening105 in thepouch wall103 as shown inFIG. 3A. In the enlarged depiction of the exit site inFIG. 3B, the space between thepouch opening105 and theadjacent straw120 is suitably reinforced and sealed byseal122 to prevent leakage of fluid around the exterior of thestraw120.Seal122 is also of sufficient strength to prevent removal of thestraw120 from thepouch100. The seal can be accomplished with a ring of adhesive material surrounding thestraw120 at theexit site105 inpouch wall103. Alternatively, a molded plastic exit port can be affixed toside wall103 to which thestraw segments121 and123 are attached.
An alternate configuration ofpouch100 is depicted inFIGS. 4A and 4B.Straw120 exits athole115 formed at the apex of thepouch100 formed by the intersection of thetop edges113 and114 of thefront wall103 andback wall104, respectively, of thepouch100.Hole115 is sealed around thestraw120 byseal122, again preventing egress of fluid except through thestraw lumen128.
Thestraw120, when folded into the closed position as shown inFIG. 5A, has afold125 which occludes thestraw lumen128 preventing the movement of fluid or air into or out of the sealedpouch100.Straw segment123 is maintained in close proximity tostraw segment124 to createfold125.FIG. 5A has an arrow depicting the direction of movement ofstraw segment124 with respect tosegment123 resulting in the straightening of the straw in order to access the contents of thepouch100.Adhesive tape141 keepsstraw segments123 and124 in close proximity thus maintainingfold125. As thestraw segment124 is lifted away from thepouch wall103, theadhesive tape141 is disrupted andstraw segments123 and124 can move away from each other as depicted inFIG. 5B. Finally, in the open position shown inFIG. 5C, the occlusion of thestraw120 byfold125 is eliminated and fluid may pass through thelumen128 of thestraw120.
Thestraw120 is comprised of material of sufficient strength to withstand the folding without rupture or breakage of the sidewall or a permanent bend. The diameter and elasticity of thestraw120 can be modified to achieve sufficient occlusion when thestraw120 is folded and sufficient resilience so that when thestraw120 is extended as shown inFIG. 5C, fluid is permitted to flow out of the container.
Another alternate embodiment, shown inFIG. 6, utilizes additional folds instraw120. Two folds (135 and136) betweenstraw segments133,134, and137 provide additional security against the egress of fluid.
As depicted inFIG. 1, a piece ofadhesive tape141 may be placed across the folded straw segments at or near thefold125 for securing the straw to the package. Other methods can be utilized to maintain the folded state of the straw as shown inFIG. 7. As depicted inFIG. 7A, anadhesive substance142 can be positioned between the straw segments to maintain the folded state. Also, a paper or plastic sleeve143 (FIG. 7B) or rubber band144 (FIG. 7C) may encircle both straw segments adjacent to thefold125. Additionally, as shown inFIG. 7D, aplastic sheet145 may cover both the folded straw and the end of the straw protecting both items. Other mechanisms may also be employed to maintain proximity ofstraw segments123 and124.
Returning toFIG. 1, the location of thefold125 in the straw is immaterial so long as it prevents fluid movement into or out of the pouch. The preferred location is at or near theexit105 of the straw from thepouch100.
A protective plastic sleeve or covering151 can be included to protect the exposedexternal end126 of thestraw120 from soilage. A pocket or slot within the wall of thepouch100 may also be constructed to accomplish the same.
For ease of carrying and portability, thepouch100 may have external modifications examples of which are demonstrated inFIG. 8 that permit attachment of thepouch100 to different items of clothing or carrying systems. A spring-loaded clip or buckle161 on theback wall104 can facilitate the attachment to a belt or pants pocket. Also, strategically placed holes oropenings162 in thepouch100 may allow connection to carrying straps or loops. Alternatively shown inFIG. 9, handles orstraps163 can be attached to thepouch100, for example, allowing easier holding and manipulation by a child.
The straw configuration and closure methods can be similarly applied to other forms of packaging including drink boxes or the like. The key elements of the folded straw preventing fluid egress are similar to those outlined above with a drink pouch.
FIG. 10 illustrates the preferred embodiment of adrink box200 with anintegrated straw220 exiting from thefront face201 of thebox200. Construction of drink box type beverage containers is well known to the art. Typically, drink boxes are manufactured from laminated cardboard configured to hold beverages or other foodstuffs.Straw220 is integrated into thepackage200 to provide access to its contents.
Straw segment221 is internal to thebox200 and is of sufficient length to permit fluid to be withdrawn from the bottom of thebox200.Straw220 exits at anopening205 in thefront face201 and has afold225 which prevents movement of fluid into or out of thebox200.Adhesive tape241 maintains thefold225 in thestraw220. An optionalprotective sleeve251 reduces potential contamination of the exposed end of thestraw220.
When theadhesive tape241 is disrupted and the straw straightened as inFIG. 11, fluid flows through thestraw220.
FIG. 12 demonstrates another embodiment incorporating a plurality of straw folds and exit of thestraw320 from the top302 of thebox300. Onefold322 is formed at the straw'sexit322 from thebox300, and anotherfold325 is formed proximal to thedrinking end326.
Accordingly, the straw integrated in the beverage container, such as a pouch or box, provides convenient fluid storage and easy access to its contents. When the straw is folded, the straw lumen is occluded and the fluid contents are securely contained within the packaging. Any of a number of methods can assist in maintenance of the straw fold. When the straw is straightened, the fold is opened and fluid can flow freely out of the container. Furthermore, this packaging closure and access method permits closure of a number of container configurations from pouches to drink boxes; allows placement of the exit site of the straw in various locations; permits the straw fold to be located on various points along the exterior portion of the straw; and provides easy opening of the container without the need for a separately affixed straw, positioning of the straw, and puncturing of the container.
Fluids (i.e., non-solids) other than beverages may be stored inpouch100,box200 orbox300. Examples of other fluids include cooking oil, motor oil, paint, and shampoo. Additionally, the container can be configured with straws of different thicknesses, colors, or shapes. Furthermore, the fold can be secured to the front face, folded over the top edge of the package, or the like.
From the above description, it will be apparent that the invention disclosed herein provides a novel and advantageous fluid container with an integrated straw. The foregoing discussion discloses and describes merely exemplary methods and embodiments of the present invention. One skilled in the art will readily recognize from such discussion that various changes, modifications and variations may be made therein without departing from the spirit and scope of the invention. Accordingly, disclosure of the present invention is intended to be illustrative, but not limiting, of the scope of the invention, which is set forth in the following claims.
