Abstract
A duplex storage pouch capable of storing a segregated liquid and powder for extended periods. The two ingredients are separated by a frangible chevron-shaped seal. When pressure is applied to the pouch, one or more chevron points lying along the chevron-shaped seal rupture, allowing the two ingredients to mix. The pouch is flexible, so that the user can knead the two ingredients together for thorough mixing. Once the mixing is complete, a peelable cover is removed to expose a dispensing opening.
Description
- This invention relates to the field of disposable packaging. More specifically, the invention comprises a flexible pouch capable of separately storing two materials which must be mixed prior to use.
- 2. Description of the Related Art
- Many materials in use today must be stored as two separate components for extended periods prior to use. Good examples include two-part adhesives, chemiluminescent lighting devices, plaster compounds, and dental alginates. Packages for these categories have existed for many years. These packages must keep the components separate, yet allow for their convenient combination just prior to use.
- Some prior art packages contemplate mixing the two components outside the package (such as epoxy dispensers), whereas others contemplate mixing the two componens inside the package (such as chemiluminescent lighting tubes). In the case of dental alginates, it is often desirable to mix the ingredients inside an enclosed space. This avoids consistency variations owing to changing humidity. It also avoids creating a mess in a separate container. Thus, a packaging concept which allows the mixing of components inside an enclosed volume, as well as allowing the convenient dispensing of the components once they are mixed, is desirable.
- The present invention comprises a duplex storage pouch capable of storing a segregated liquid and powder for extended periods. The two ingredients are separated by a frangible chevron-shaped seal. When pressure is applied to the pouch, one or more chevron points lying along the chevron-shaped seal rupture, allowing the two ingredients to mix. The pouch is flexible, so that the user can knead the two ingredients together for thorough mixing. Once the mixing is complete, a peelable cover is removed to expose a dispensing opening.
- FIG. 1 is an isometric view, showing the present invention.
- FIG. 2 is an isometric, showing the components of the present invention prior to assembly.
- FIG. 3 is an isometric, showing a first alternate embodiment.
- FIG. 4 is an isometric view, showing a plurality of pouches joined together to form a dispenser strip.
- FIG. 5 is an isometric view, showing a second alternate embodiment.
REFERENCE NUMERALS IN THE DRAWINGS 10 duplex storage pouch 12 liquid chamber 14 powder chamber 16 permanent seal 18 frangible chevron seal 20 peelable cover 22 pull tab 24 chevron point 26 back panel 28 front panel 30 dispensing opening 32 printed cut line 34 dispenser strip 36 integral pull tab 38 tear-promoting notch 40 perforated joint - FIG. 1 shows
duplex storage pouch 10 in its assembled state. FIG. 2 shows the same components prior to assembly.Front panel 28 is laid overback panel 26. Both panels are preferably made of thin and flexible plastic—such as polypropylene. Returning now to FIG. 1, once the two panels are aligned,permanent seal 16 is formed around the perimeter, so as to create an enclosed internal volume.Permanent seal 16 may be formed by an adhesive, or by simply thermally fusing the plastic material together. - The internal volume is divided into
liquid chamber 12 andpowder chamber 14 by the addition offrangible chevron seal 18.Frangible chevron seal 18 is preferably formed by thermally or ultrasonically fusing the two panels together in the illustrated chevron pattern. The thickness of this seal is typically less thanpermanent seal 16. - In FIG. 2, the reader will observe that one corner of
front panel 28 is cut away to form dispensing opening 30. A portion of this opening lies outside the fused region ofpermanent seal 16, meaning that it allows fluid communication between the interior ofduplex storage pouch 10 and the surrounding environment. Returning now to FIG. 1,peelable cover 20 is adhesively affixed over dispensing opening 30.Peelable cover 20 includespull tab 22, which allows a user to grasp it and pull it free when the contents are ready for dispensing.Peelable cover 20 is preferably made from a thin metal foil with an adhesive backing, similar to the tabs used on metal juice containers and similar items. - Of course, the powder and liquid must be deposited within
duplex storage pouch 10 prior to the completion ofpermanent seal 16. Looking at FIG. 1, the top, right-hand, and bottom portions ofpermanent seal 16 are typically formed.Frangible chevron seal 18 is then added, along withpeelable cover 20.Duplex storage pouch 10 is then rotated 90 degrees in the clockwise direction, so that the remaining open side ofpermanent seal 16 is facing upward. The powder and liquid are then deposited in the two segregated chambers. The fourth side ofpermanent seal 16 is then formed. - When the user is ready to dispense the mixed material, he or she squeezes
duplex storage pouch 10. This results in pressure alongpermanent seal 16 andfrangible chevron seal 18.Permanent seal 16 is made stronger thanfrangible chevron seal 18. The shape offrangible chevron seal 18 also causes substantial stress concentration at thechevron points 24. The result is that chevron points 24 rupture, dispersing the liquid into the powder. Two ormore chevron points 24 are preferably used, since this construction will promote the rupture of the frangible seal at two or more locations (resulting in easier mixing). - The user then kneads the liquid and powder together within the flexible pouch. Once the mixing process is complete, the user pulls away
peelable cover 20. The pouch is then squeezed to extrude the mixture through dispensing opening 30. - FIG. 3 shows an alternate embodiment of the invention, in which dispensing opening30 and
peelable cover 20 are omitted. Instead, a printedcut line 32 is printed on the pouch to indicate to the user that a pair of scissors or a knife should be used to cut the pouch once its contents are ready for dispensing. Instructions may also be printed directly on the pouch. - Although
duplex storage pouch 10 has been illustrated in FIGS. 1 through 3 as a single unit, the use of an assembly line favors production as a plurality of connected units. FIG. 4show dispenser strip 34, which is comprised of a series of joinedduplex storage pouch 10. In this embodiment,back panel 26 andfront panel 28 are formed from long strips of plastic material instead of individual squares. Each individualduplex storage pouch 10 is separated from its neighbor by aperforated joint 40. When the user needs an individual pouch, he or she simply tears one free of thedispenser strip 34. It is then used in the manner described previously. The use of such strips allows manyduplex storage pouches 10 to be transported in a box or in roll form. It also allows the use of wall-mounted dispensers. - Those skilled in the art will realize that many variations are possible on the basic design presented. FIG. 5 shows a second alternate embodiment which eliminates the need for
peelable cover 20. In this embodiment, the perimeter of eachduplex storage pouch 10 is given a rounded shape to assist the user in squeezing and kneading the contents. The mixed material is dispensed from the lower portion of the pouch in the view as shown. Integral pull tab 36 is actually formed as a part of the front and back panels. Tear-promoting notch is formed just above it. When the mixed materials are ready for dispensing, the user grasps integral pull tab 36 and pulls it in the direction indicated by the arrow. The bottom of the pouch will then tear free, allowing the material to be dispensed. - Although the specific example of a liquid and a powder was disclosed in detail, the reader should keep in mind that the devices disclosed could be used to store two liquids as well. They could also store and segregate two powders, although mixing of two powders might be difficult. The preceding descriptions should not be construed, therefore, as limiting the scope of the invention but rather as providing illustrations of the preferred embodiments of the invention.
