Abstract
A dual-layer package for pasty substance is composed of internal layer, external layer and an air layer between internal and external layers. The air inlet of said air layer has a sealing ring. When external shell is pressed, the air inlet is sealed by said sealing ring and the air is compressed to sequence the internal layer, so extruding the pasty substance out. Its external shell is elastic, so it can not be deformed.
Description
Involved in the present invention is a kind of cream packing bags, particularly a kind of double-deck packaging bag of packing paste medicine, cosmetics, toothpaste and various pastes.
All have such sensation with toothpaste and various packed paste cosmetics, medicine every day, new relatively good making good use of extruded, difficult more with extruding more backward, packaging bag squeezed shapeless shape, paste can't be squeezed only, must with the hands come to squeeze unspent toothpaste, medicine, cosmetics etc. finally.
The purpose of this invention is to provide a kind ofly by O RunddichtringO leak free double-decker cream packing bags, transmit squeese pressure with the pressurized air between the ectonexine bag paste is extruded, its can solve the existing existing deficiency of cream packing bags by actv..
The object of the present invention is achieved like this, constitute a double-deck packaging bag with two packaging bags that are nested inside and outside small one and large one, the inner layer bag softness of packing paste does not have elasticity to be out of shape with the minimizing of paste, can resilience restore after the flexible extruding of outer bag, space between the ectonexine bag constitutes the leak free energy chamber, and energy chamber outwards is that the admission port by the ring shape that forms between the ectonexine bag sack that is nested communicates with atmosphere.Admission port constitutes the groove of an assembling O-ring seals between inherent two sacks.O-ring seals in groove with the formed axle of internal layer sack, be to float to cooperate between the formed hole of outer sack.When the extruding outer bag, the increased pressure air in the energy chamber is lived in gas port with the outside closedtop of O-ring seals, and the air in the energy chamber promptly is compressed, and the air of pressurized passes to inner layer bag with squeese pressure extrudes paste.Remove the squeese pressure outer bag and can resilience restore the interior pressure reduction of energy chamber simultaneously, the air of outside promptly inwardly backs down O-ring seals and enters energy chamber through admission port, replenish the volume that paste deducted that is extruded, repeated use uses up up to paste like this, and packaging bag remains full handy state.
The invention has the advantages that: 1, random push-through packs bag, to the extruding of any one point of outer bag, the transmission of compressed air all can form monolithic extruded to internal layer, so extruding of the distortion of inner layer bag and paste all is uniform.2, outer bag is indeformable, all the time as new.
Below in conjunction with accompanying drawing to operation further instruction of the present invention
Figure one is a structural representation of the present invention, wherein: 1. o-ring groove, 2. admission port, 3. in sack, 4. outer sack, 5.O shape seal ring, 6. outer bag, 7. energy chamber, 8. inner layer bag.
Packaging bag with reference to figure one is made up of inner layer bag 8 outer bags 6 and the O-ring seals 5 that are nested.The inner layer bag 8 of packing paste is soft not to have the elasticity can be with the minimizing distortion of paste, can resilience restore after the outer bag 6 flexible extruding, space between inner layer bag 8 and the outer bag 6 constitutes leak free energy chamber 7, and energy chamber 7 outwards is that the ring shape admission port 2 that forms after being nested by interior sack 3 outer sacks 4 communicates with atmosphere.Constituting the groove 1 of an assembling O-ring seals in admission port 2 inner faces between sack 3 and the outer sack 4, is to float to cooperate between the hole that sack 4 forms outside the axle that O-ring seals 5 forms with interior sack 3 in groove 1.Increased pressure when outer bag 6 is squeezed in the energy chamber 7, air is lived in gas port 2 with O-ring seals 5 outside closedtops, and the air in the energy chamber 7 promptly are compressed, and the air of pressurized passes to inner layer bag 8 with squeese pressure paste is extruded.Removing pressure outer bag 6 is that resilience is restored, and the pressure in the energy chamber 7 reduces simultaneously, and the air of outside inwardly backs down O-ring seals 5 and enters the energy chamber 7 additional volumes that paste deducted that are extruded through admission port 2.
Claims (3)
1, a kind of paste medicine of packing, cosmetics, the double casing bag of toothpaste and various pastes, the interior sack of inner layer bag (8) (3) by the packing paste constitutes, inner layer bag (8) outside that it is characterized in that packing paste is with outer bag (6), space between outer bag (6) and the inner layer bag (8) constitutes leak free energy chamber (7), energy chamber (7) is outwards by interior sack (3), the ring shape admission port (2) that forms after outer sack (4) is nested communicates with atmosphere, constitute O-ring seals groove (1) between sack (3) and the outer sack (4) in admission port (2) inner face, O-ring seals (5) groove (1) in interior sack (3) formation spool outside be unsteady the cooperation between the hole of sack (4) formation.
2, double-layer cream packing bags according to claim 1 is characterized in that inner layer bag (8) softness does not have elasticity to be out of shape with the minimizing of paste.
3, double-layer cream packing bags according to claim 1 is characterized in that resilience restoring after the flexible extruding of outer bag (6).
