an upper flange having an upper flange region; and a lid attached to the upper flange with at least a first region with a first bond strength to survive a drop test, and a second region with a second bond strength for easy opening. ## Claims ### Claim 1 A container comprising: a lower wall portion to contain a liquid, gas or viscous material therein; an upper flange having an upper flange region; and a lid attached to the upper flange with at least a first region with a first bond strength to survive a drop test, and a second region with a second bond strength for easy opening. ### Claim 2 (depends on 1) The container of claim 1 wherein: the upper flange region contains a second region with a weak bond strength located outside the first region to easily open the container when pulling on a tab. ### Claim 3 (depends on 1) The container of claim 1 wherein: the lid comprises a second centrally located lid attached thereon and openable by pulling on a tab connected to a second lid, and wherein the second centrally located lid has coverage to survive the drop test. ### Claim 4 (depends on 3) The container of claim 3 wherein: the first lid has a pre-opening aperture lying directly below the second lid. ### Claim 5 (depends on 1) The container of claim 1 wherein: the lid includes a tab outside the first region with the first bond strength, wherein the tab includes at least one pre-weakened point to initiate a tear across the lid. ### Claim 6 (depends on 1) The container of claim 1 further comprising: a second outer rigid container having a durable cap with a self-opening system that punctures or severs a portion of the lid. ### Claim 7 (depends on 1) The container of claim 1 further comprising: a second outer rigid container with a durable cap including at least one of the following: a pump system or a spray system. ### Claim 8 (depends on 1) The container of claim 1 wherein: the upper flange contains one or more handling ears. ### Claim 9 (depends on 1) The container of claim 1 wherein: differences in bonding strength are formed with differential adhesives, differential sealing properties, or treatment processes. ### Claim 10 (depends on 1) The container of claim 1 wherein: the lid's film quality and orientation propagate a straight line tear. ### Claim 11 (depends on 6) The container of claim 6 wherein: the container operates with a stemless pump or spray. ### Claim 12 A dispensing system comprising: a first container comprising a lower wall portion to contain a liquid, gas or viscous material therein; and an upper flange seated atop a second outer rigid container with a cap that contains a self-piercing system to pierce an underlying lid membrane. ### Claim 13 (depends on 12) The dispenser of claim 12 wherein: the self-piercing system is actuated by pushing downwardly into a lid membrane. ### Claim 14 (depends on 12) The dispenser of claim 12 wherein: the self-piercing system is actuated by screwing a cap onto the second rigid container and piercing a lid membrane as a cap is secured on the first container. ### Claim 15 (depends on 12) The dispenser of claim 12 wherein: the self-piercing system is an integral part of a spray head unit, or a pump unit. ### Claim 16 (depends on 12) The dispenser of claim 12 wherein: the self-piercing system is an integral part of a nozzle. ### Claim 17 A method of dispensing a material comprising: providing a first sealed container containing a liquid, gas or viscous material therein; sealing the container with a lidding membrane; providing a second outer rigid container comprising a cap with a self-piercing device; placing the first sealed container into the second outer rigid container; securely fastening the cap to the outer rigid container and; actuating the self-piercing device to dispense the material. ### Claim 18 (depends on 17) The method of claim 17 further comprising: actuating the self-piercing device as the cap is secured to the outer rigid container. ### Claim 19 (depends on 17) The method of claim 17 wherein: the cap comprises a pump or spray head. ### Claim 20 (depends on 17) The method of claim 17 wherein: the outer container is sufficiently flexible to squeeze a liquid, gas or viscous material out of an exit port.
