Abstract

An inflatable pouch includes a bladder formed from an inflatable web and an outer skin formed from a film. The bladder includes a bladder pouch that includes a bottom portion at a folded edge of the inflatable web, front and back portions on either side of the folded edge, and sides where the front and back portions are sealed to each other. The outer skin includes an outer skin pouch that includes a bottom portion at a folded edge of the film, front and back portions on either side of the folded edge, and sides where the front and back portions are attached to each other. The bladder is attached to the outer skin at a tack area such that the sides of the bladder pouch and the outer skin pouch are not directly attached to the sides of the outer skin pouch.

Claims (31)

1. An inflatable pouch comprising:

a bladder formed from an inflatable web, wherein the bladder includes a bladder pouch, wherein the inflatable web is folded about a bottom portion of the bladder pouch with a front portion of the bladder pouch and a back portion of the bladder pouch on different sides of the bottom portion of the bladder pouch, and wherein sides of the front portion of the bladder pouch and sides of the back portion of the bladder pouch are sealed to each other to form sides of the bladder pouch; and

an outer skin formed from a film, wherein the outer skin includes an outer skin pouch, wherein the film is folded about or sealed at a bottom portion of the outer skin pouch with a front portion of the outer skin pouch and a back portion of the outer skin pouch on different sides of the bottom portion of the outer skin pouch, and wherein sides of the front portion of the outer skin pouch and sides of the back portion of the outer skin pouch are attached to each other to form sides of the outer skin pouch;

wherein the bladder is attached to the outer skin at a tack area, and wherein the tack area does not include any portion of at least one of the sides of the bladder pouch or any portion of the sides of the outer skin pouch such that the sides of the bladder pouch are not directly attached to the sides of the outer skin pouch;

wherein the inflatable web extends from the back portion of the bladder pouch to form a flap portion of the bladder and the film extends from the back of the outer skin pouch to form a flap portion of the outer skin; and

wherein the tack area that couples the bladder to the outer skin is located in the flap portion of the bladder and the flap portion of the outer skin.

2. The inflatable pouch of claim 1 , wherein the flap portion of the bladder includes a common channel.

3. The inflatable pouch of claim 2 , wherein the inflatable web includes a plurality of inflatable cells in communication with the common channel such that the plurality of inflatable cells are inflatable by directing a gas into the common channel.

4. The inflatable pouch of claim 1 , wherein the bladder pouch is not directly attached to the outer skin pouch.

5. The inflatable pouch of claim 1 , wherein the flap portion of the bladder and the flap portion of the outer skin together form a flap of the inflatable pouch.

6. The inflatable pouch of claim 5 , wherein the flap of the inflatable pouch includes at least one hole configured to receive at least one wicket configured to suspend the inflatable pouch.

7. The inflatable pouch of claim 6 , wherein the at least one hole passes through at least one of the flap portion of the bladder or the flap portion of the outer skin.

8. The inflatable pouch of claim 6 , wherein the at least one hole is located on at least one tear away section of the flap that is configured to remain on the at least one wicket after the inflatable pouch is torn away from the at least one wicket.

9. The inflatable pouch of claim 5 , wherein the film includes an attachment zone having a release tape segment configured to close the flap of the inflatable pouch.

10. The inflatable pouch of claim 9 , wherein the release tape segment is located on at least one of a portion of the flap portion of the outer skin that extends beyond the flap portion of the bladder or an exterior surface of the front portion of the outer skin pouch.

11. A method of forming an inflatable pouch, comprising:

forming a bladder from an inflatable web, wherein the bladder includes a bladder pouch, and wherein forming the bladder includes:

folding the inflatable web along a bottom portion of the bladder pouch with a front portion of the bladder pouch and a back portion of the bladder pouch on different sides of the bottom portion of the bladder pouch, and

sealing sides of the front portion of the bladder pouch to sides the back portion of the bladder pouch to form sides of the bladder pouch;

forming an outer skin from a film, wherein the outer skin includes an outer skin pouch, and wherein forming the outer skin includes:

folding the film around the bladder along or sealing the film at a bottom portion of the outer skin pouch with a front portion of the outer skin pouch and a back portion of the outer skin pouch on different sides of the bottom portion of the outer skin pouch, and

attaching sides of the front portion of the outer skin pouch to sides the back portion of the outer skin pouch to form sides of the outer skin pouch; and

attaching the bladder to the outer skin at a tack area, wherein the tack area does not include any portion of at least one of the sides of the bladder pouch or any portion of the sides of the outer skin pouch such that the sides of the bladder pouch are not directly attached to the sides of the outer skin pouch, wherein the inflatable web extends from the back portion of the bladder pouch to form a flap portion of the bladder and the film extends from the back of the outer skin pouch to form a flap portion of the outer skin, and wherein the tack area that couples the bladder to the outer skin is located in the flap portion of the bladder and the flap portion of the outer skin.

12. The method of claim 11 , wherein the inflatable web is formed from a continuous inflatable web sheet and the film is formed from a continuous film sheet.

13. The method of claim 12 , wherein the sealing includes cut sealing the inflatable web between consecutive bladders formed from the continuous inflatable web sheet, and wherein the attaching includes sealing the film between consecutive outer skins formed from the continuous film sheet.

14. The method of claim 12 , wherein folding the inflatable web includes J-folding the inflatable web such that the inflatable web extends from the back portion of the bladder pouch to form a flap portion of the bladder, and wherein folding the film includes J folding the film such that the film extends from the back portion of the outer skin pouch to form a flap portion of the outer skin.

15. The method of claim 12 , wherein:

attaching the sides of the front portion of the outer skin pouch to the sides of the back portion of the outer skin pouch to form the sides of the outer skin pouch includes forming seals along the sides of outer skin pouches of consecutive inflatable pouches in the continuous film sheet and along edges of flap portions of the consecutive inflatable pouches in the continuous inflatable web sheet and the continuous film sheet; and

the method further comprises forming weakened portions between seals in the sides of the outer skin pouches and the edges of the flap portions of consecutive inflatable pouches.

16. The method of claim 15 , wherein the weakened portions include one of perforated lines that permit the inflatable pouch to be removed from adjacent inflatable pouches formed from the continuous inflatable web sheet and the continuous film sheet or cuts that separate adjacent inflatable pouches formed from the continuous inflatable web sheet.

17. The method of claim 15 , wherein the weakened portions include a perforated line and a slit in an interior portion of the perforated line between the consecutive inflatable pouches, wherein the slit is configured to receive a tongue that is configured to initiate breaking of the perforated line.
