Self-Sealing Dosepack

Abstract

A dose pack includes a front panel and aback panel that define an internal volume therebetween. A portion of the front panel, the back panel, or both is configured to be torn, perforated, or cut to open the dose pack. A first guide may be positioned in the internal volume and extend toward a second, opposing edge of the dose pack. A second guide may be positioned within the internal volume and extend toward the first edge. A third guide may be positioned within the internal volume. The third guide is substantially perpendicular to the first and second guides. The first, second, and third guides define a tortuous path of fluid communication through which a fluid is configured to flow, after the dose pack has been opened, in response to the dose pack being exposed to a predetermined force.

1 . A dose pack, comprising:
 a front panel and a back panel that define an internal volume therebetween, wherein a portion of the front panel, the back panel, or both is configured to be torn, perforated, or cut to open the dose pack;   a first guide positioned in the internal volume, wherein the first guide is coupled to or integral with a first edge of the dose pack and extends toward a second, opposing edge of the dose pack;   a second guide positioned within the internal volume, wherein the second guide is coupled to or integral with the second edge and extends toward the first edge; and   a third guide positioned within the internal volume, wherein the third guide is coupled to or integral with a third edge of the dose pack, wherein the third guide is substantially perpendicular to the first and second guides, and wherein the first, second, and third guides define a tortuous path of fluid communication through which a fluid is configured to flow, after the dose pack has been opened, in response to the dose pack being exposed to a predetermined force.   
     
     
         2 . The dose pack of  claim 1 , wherein the fluid comprises a toothpaste, a mouthwash, a food condiment, a pet snack, a fabric conditioner, a fabric detergent, an all-purpose cleaner, a hand or dish liquid cleaner, a body wash, a body cream, a lotion, a liquid hand soap, or a concentrate. 
     
     
         3 . The dose pack of  claim 1 , wherein a viscosity of the fluid in the internal volume is from about 0 Pa*s to about 700 Pa*s. 
     
     
         4 . The dose pack of  claim 1 , wherein the path of fluid communication has a length from about 5 mm to about 3 times a length of the first edge or the second edge. 
     
     
         5 . The dose pack of any  claim 1 , wherein the path of fluid communication has a cross-sectional area from about 2 mm to about 80 mm throughout the length. 
     
     
         6 . The dose pack of  claim 1 , wherein the path of fluid communication comprises a bend that is about 90°. 
     
     
         7 . The dose pack of  claim 1 , wherein the path of fluid communication comprises a bend that is about 180°. 
     
     
         8 . The dose pack of  claim 1 , wherein the first guide is made of a same material as the front panel and the back panel. 
     
     
         9 . The dose pack of  claim 1 , wherein the first guide is formed using an adhesive, heat sealing, or sonic welding. 
     
     
         10 . The dose pack of  claim 1 , wherein the third guide separates the internal volume into two portions. 
     
     
         11 . The dose pack of  claim 1 , wherein a distance between an end of the third guide and the second guide is from about 0.5 mm to about 50 mm. 
     
     
         12 . A dose pack, comprising:
 a front panel and a back panel that define an internal volume therebetween, wherein a portion of the front panel, the back panel, or both is configured to be torn, perforated, or cut to form an opening in the dose pack; and   first and second guides positioned within the internal volume, wherein the first and second guides are offset with respect to one another, wherein the first and second guides define a tortuous path of fluid communication through which a fluid is configured to flow after the dose pack has been opened in response to the dose pack being exposed to a predetermined force, and wherein the path of fluid communication is not defined by one or more edges of the dose pack.   
     
     
         13 . The dose pack of  claim 12 , wherein the path of fluid communication comprises a curvi-linear bend. 
     
     
         14 . The dose pack of  claim 12 , wherein the opening is formed proximate to a corner of the dose pack, the corner being at an intersection of two edges of the dose pack, wherein one or both of the two sides comprises a recess, and wherein the first guide is shaped to conform to the recess. 
     
     
         15 . The dose pack of  claim 12 , wherein the path of fluid communication comprises a spiral-shaped bend. 
     
     
         16 . The dose pack of  claim 12 , wherein a width of the path of fluid communication varies proceeding along a central axis through the path of fluid communication. 
     
     
         17 . The dose pack of  claim 12 , wherein the first and second guides are configured to be inserted into the internal volume of the dose pack through the opening after the front panel, the back panel, or both is torn to form the opening. 
     
     
         18 . The dose pack of  claim 12 , wherein the first and second guides are not part of a straw that is used to suck the fluid out of the internal volume. 
     
     
         19 . A dose pack, comprising:
 a front panel and a back panel that define an internal volume therebetween, wherein:
 an opening is formed through an upper edge of the dose pack, 
 a width of the opening is from about 5% to about 50% of a width of a lower edge of the dose pack, and 
 a first side edge of the dose pack is substantially perpendicular to the upper edge. 
   
     
     
         20 . The dose pack of  claim 19 , wherein at least a portion of a second, opposing side edge of the dose pack is oriented at an angle from about 20° to about 90° with respect to the first side edge, and wherein the opening is sealed using a snap-lock feature or a sliding mechanism.
