• the needle 101 is exposed to conveniently apply to a patient. It will be obvious to those skilled in the art that the sequence of incremental steps presented between Figure 10c and 1Of can be performed as one continues action by merely folding the compression panel 17 over the backing 16. It will also be obvious to those skilled in the art that the needle 101 can be directly associated to the backing 16 to eliminate the needle hub.

• the proximal end of the needle 101 is fixed to the backing 16, the turning of the compression panel 17 forces the needle to bend and be destroyed such that the device 130 cannot be reused, or the remaining product in the package cannot be abused.
• the needle 101 tip is protected from causing needle sticks after the product has been discarded.
• the device 130 comprises a feature that latches the backing 16 and the compression panel 17 in the discarded position such that the flaps can not be separated and the needle cannot be accessed once the device 130 is folded to this position.
• the springs 141 bias into a first stable position in which the compression panel 17 lays flat with the backing 16 and a second stable position in which the compression panel 17 is folded over the backing 16 in the dispensing position.
• the first stable position is when the compression panel 17 is partly folded over the backing 16, such that when the device 140 is removed from the package and is released from the flat position, the compression panel 17 will snap to the semi-folded position.
• FIG 15 illustrates a further preferred embodiment.

• the proximal end of the fluid transport device 14 is in the form of a pouch insert fitment and is sealed between the two flexible walls 11' and 11".
• the distal end of the fluid transport device 14 is a hypodermic needle 101, which at the pre-use state is confined between the backing 16 and the compression panel 17 which serve as a needle protector.
• the fluid transport device 14 further comprises a laterally extending platform 162 to which the first flap 16 and the second flap 17 are joined via a living hinge 18, such that each of the backing 16 and the compression panel 17 can pivot in opposite directions about 180 degrees toward the package 9.
• Each of the backing 16 and compression panel 17 further comprises a cantilever spring section 163 which extends from the distal edge of the backing 16 and compression panel 17 toward their proximal end.
• Figure 16b illustrates an intermediate position during the turning of backing 16 and compression panel 17. The backing 16 and compression panel 17 are pivoted around their hinges 18 toward the package 9, thereby exposing the needle 101.
• Figure 16c illustrates the device 160 after the backing 16 and compression panel 17 have been completely folded back such that their distal ends are touching each other.
• the backing 16 is supporting the package 9 and the compression panel 17 is partly squeezing the package 9 against the compression panel 16 causing the product compartment 12 to merge with the second compartment 21 and the outlet seal 13 to separate and establish fluid communication with the fluid transport device 14.
• the arrangement is such that an only insignificant portion of the contents of the merged compartment 12' may expel at this position through the fluid transport device 14.
• the rotation of the backing 16 and compression panel 17 to this position does not separate the frangible seal and fluid communication is not being established between the merged compartment 12' and the fluid transport device.
• the rotation of the backing 16 and compression panel 17 to this position causes the outlet seal 13 to only partly separate such that fluid communication is not being established between the merged compartment 12' and the fluid transport device.
• the outlet seal 13 is made such that the seal force is gradually lowering toward the fluid transport device 14, and the frangible seal 13 is partly separated such that fluid communication is not being established between the merged compartment 12' and the fluid transport device, but the force for separating the remaining part of the outlet seal 13 is lower than the force that was required for separating the initial portion of the frangible seal 13.
• Figure 16d illustrates the device 160 at the dispensing stage.
• the fingers of the user are repositioned to press on the cantilevers 163 causing the cantilevers 163 to deflect and further squeeze the merged compartment 12' thereby causing the contents to expel until the backing 16 and compression panel 17 contact one another and the merged compartment is emptied.
• the cantilever springs 163 are connected in at least one additional location beside the joint 18, through a rupturable bridge which will : a) provide initial resistance to avoid unintentional squeezing of the merged compartment 12', and b) serve as evidence that the device 160 has not been tampered with.
• FIG 17 a further preferred embodiment 170 is illustrated which comprises a flow regulator in the dispensing passage to avoid a burst of the contents when the device 170 is activated.
• Figure 17a illustrates a general view of the first side of the device, showing a package 9 similar to embodiment 100 of Figure 10, here the arrangement of the package 11 is turned in the opposite direction such that the fluid passageway 13 is facing away from the fold line 18.
• the proximal end of the channel (right side in this figure) comprises an opening for accommodating the needle hub 102 such that flow entering the channel 171 will proceed through the channel 171 and into the needle 101.
• the purpose of the labyrinth 172 is to cause pressure dampening which increases with the increase in the flow rate.
• Figure 17d illustrates a broken section view along the flow channel 171 of the device 170 showing the device immediately after activation.
• the device 170 is already activated and a relatively high pressure is generated in the merged compartment 12'. This situation may occur at the instant after the device 170 was activated when the fingers of the user still exert relatively high force on the backing 16 and compression panel 17, which was required to rupture the frangible seal 13.
• the flow advances from the merged compartment 12' through receptacle 175 and into labyrinth 172 where it loses substantial pressure such that the flow received in the regulating stretch 173 is substantially lower than the pressure in the merged compartment 12'.
• the package is distorted such that the section of the additional wall 73 is stretching down into the regulating straight 173 and the cross section of the regulating straight 173 is reduced.
• the distortion of the package reduces the flow rate of the expelling fluid, thereby preventing bursting of the dispensable fluid through the fluid transport device 14.
• the device comprises a one way valve for avoiding refilling of the product compartment after completion of the intended first use.
• the device comprises a time indicator which indicates a period of time elapsed since activation.
• the device may further include child protection such that it will be challenging to operate the device by a child, thereby avoiding accidental dispensing or needle sticks.
• the backing 16 now has a second fold line 181 which is located directly under the product compartment 12, and defining a second compression panel 182 within the backing 16.
• the package 9 is supported by the backing 16 and said second compression panel 182.
• the arrangement is such that the flap 182 can only be manipulated to pivot toward the first compartment 12 (and not from the flat position away from the product compartment 12), thereby causing the first compartment 12 to pressurize.
• the folding of the second compression panel 182 serves to squeeze the first compartment 12, causing it to merge with the second compartment 21 and/or with additional compartments.
• the folding of the third flap 182 serves to squeeze the first compartment 12 and thereby rupture the frangible seal 13 and establish fluid communication with the fluid transport device 14.
• the first compression panel 17 is eliminated and the second compression panel 182 serves for dispensing the product.
• Figure 18a illustrates the device 180 at a pre-activation position. The shoulder 183 in the backing 19 and the flap 182 prevent the flap 182 from pivoting downwardly and away from the product compartment.
• Figure 18b illustrates the device 180 after the flap 182 is rotated and the first compartment 12 has merged with the second compartment 21.
