Sealed delivery unit 10 (shown in exploded format in FIG. 1A) contains medication 10M, and is formed by a generally flat member 10F pressed into selective engagement with an opposed shaped member 10S. Pumping chamber 12P, enclosed between the members generates a rupturing pressure in response to an external force applied by the user (indicated by arrow F shown in FIG. 1B). Enclosed Medication chamber 12M contains the medication to be delivered. Tunnel conduit 14 provides fluid communication between the chambers for rupturing the medication chamber in response to the rupturing pressure. Perimeter seal 16 extends around the pumping chamber and the medication chamber and the tunnel conduit. The perimeter seal is secure enough to withstand the internal rupturing pressure generated during delivery. Delivery port 18 with pull-away closure 18C (see FIG. 1C) delivers the medication out of medication chamber 12M. Rupture site 18S is proximate the delivery port. Rupture flap 18F produced by the rupturing at the rupture site, is connected to the pull-away closure. The flap projects outward permitting the user to grasp the pull-away the closure and open the delivery port for delivery of the medication.

I claim: 1. A sealed unit for delivering a product in response to a rupturing pressure, comprising: a generally flat member; a shaped member opposed to the flat member, and pressed into selective engagement with the flat member; a pumping volume enclosed between the flat member and the opposed shaped member for generating the rupturing pressure in response to an externally applied force; a product volume enclosed between the flat member and the opposed shaped member for containing the product to be delivered; fluid communication between the pumping volume and the product volume permits the rupturing the product volume in response to the rupturing pressure from the pumping volume; a product contained in the product volume; a perimeter seal formed during the selective pressing engagement, and extending around the pumping volume and the product volume, which perimeter seal can withstand the rupturing pressure; a delivery port with a pull-away closure for delivering the product out of the product volume; a rupture site proximate the delivery port which ruptures outward under the rupturing pressure; and a rupture flap produced by the rupturing at the rupture site, and connected to the pull-away closure, permitting pulling away of the pull-away closure to open the delivery port for delivery of the product contained within the product volume. 2. The delivery unit of claim 1, wherein the sealed pumping volume is a pumping chamber, and the sealed product volume is a product chamber. 3. The delivery unit of claim 2, further comprising: a tunnel conduit within the perimeter seal, formed between the flat member and the opposed shaped member by the selective pressing engagement, having a pumping entrance opening from the pumping chamber and a product exit opening into the product chamber, and providing the fluid communication from the pumping chamber into the product chamber. 4. The delivery unit of claim 3, further comprising: an interior seal for sealing-off the tunnel conduit between the product chamber and the pumping chamber, which interior seal fails under the rupturing pressure. 5. The delivery unit of claim 1, further comprising a perimeter lip around the flat member; an opposed perimeter lip around the shaped member; which perimeter lips form the perimeter seal around the pumping volume and the product volume during the selective pressing engagement. 6. The delivery unit of claim 5, wherein the perimeter seal is hermetic. 7. The delivery unit of claim 5, wherein the flat member and the perimeter lips are coplanar. 8. The delivery unit of claim 1, wherein the flat member further comprises: a tough layer pressed against the shaped layer; and a hermetic foil layer pressed against the tough layer. 9. The delivery unit of claim 1, wherein the delivery port out of the sealed product volume is through the flat member, and the rupture site is a rift in the flat member. 10. The delivery unit of claim 9, wherein the rupture site rift is a score in the flat member. 11. The delivery unit of claim 9, further comprising: a rupture seal forming a weak section of the perimeter seal at the rupture site, which cannot withstand the rupturing pressure and causes the rupturing of the rupture flap. 12. The delivery unit of claim 9, wherein the rupture flap is a triangular piece of the flat member covering at the rupture site. 13. The delivery unit of claim 9, wherein the pull-away closure of the delivery port is defined by a tear-away border within the perimeter seal around the product volume. 14. The delivery unit of claim 13, wherein the tear-away border is a series of perforations in the flat member. 15. The delivery unit of claim 13, wherein the tear-away border is a score in the flat member. 16. A sealed system for delivering medications in response to a rupturing pressure, comprising: a flat member; a shaped member opposed to the flat member, and pressed into selective engagement with the flat member; a plurality of delivery units enclosed between the flat member and the opposed shaped member; a pumping chamber within each delivery unit for generating the rupturing pressure; a medication chamber within each delivery unit for containing the medication to be delivered; fluid communication between the pumping chamber and the medication chamber, for communicating the rupturing pressure from that pumping chamber to the medication chamber; a medication contained in each medication chamber; a perimeter seal formed during the selective pressing engagement to withstand the rupturing pressure, and extending around the delivery units for sealing the pumping chambers and the medication chambers; a delivery port with a pull-away closure out of each medication chamber for delivering the medications in the sealed medication chambers; a rupture site proximate each delivery port which ruptures outward under the rupturing pressure; and a rupture flap produced by the rupturing of the rupture site, and connected to the pull-away closure, permitting pulling away of the pull-away closure to open the delivery port for delivery of the medication contained in the medication chambers. 17. The sealed delivery system of claim 16, wherein each delivery unit is elongated with a pumping end for the pumping chamber and a medication end for the medication chamber; and the delivery units are arranged adjacently side-by-side with the pumping chamber of each delivery unit next to the medication chamber of the adjacent delivery unit in alternating sequence. 18. The sealed delivery system of claim 17, wherein: the pumping chambers are dome-shaped for easy compression under the rupturing pressure; and the medication chambers have rigid sidewalls for providing spaced barriers between alternate pumping chambers. 19. The sealed delivery system of claim 18, wherein the barrier spacing is wide enough to permit applying an external force to the pumping chamber for generating the rupturing pressure. 20. The sealed delivery system of claim 18, wherein the dome-shaped pumping chambers may be sufficiently resilient to regain the dome-shape after compression.
