Inflatable, reusable and leak-resistant carrier
View Patent ↗A protective carrier ( 10 ) for portable objects has an interior layer ( 30 ) and an exterior layer ( 20 ) welded together to form a compartment ( 2 ) that is surrounded by inflatable air chambers ( 3 ). The compartment ( 2 ) has an opening in one end ( 62 ) through which objects are inserted. The open end ( 62 ) may be closed with a fluid-resistant seal ( 65 ) that rolls and is secured by buckles ( 40, 70 ), making the compartment ( 2 ) leak-resistant. The air chambers ( 3 ) may be inflated and deflated through a valve ( 100 ).
1. A carrier, comprising:
an exterior layer and an interior layer, the edges of the exterior layer and the interior layer welded together to form first and second edge seams and at least two inflatable air chambers that at least partially surround a compartment, the air chambers capable of inflation and deflation by means of at least a first valve penetrating the exterior layer at a valve end of the compartment, the valve end comprising a fold in the exterior and interior layers, the compartment able to contain at least one object, the compartment having an insertion end disposed opposite the valve end, the insertion end capable of opening to allow insertion of an object into the compartment, the insertion end having a seal that may be rolled to form a leak-resistant closure that isolates an object within the compartment from the external environment, the seal comprising a first portion and a second portion of the interior layer welded together at at least a first edge and a second edge, the first and second edges disposed on opposite sides of the first and second portions of the interior layer to form an opening in the insertion end between the compartment and the external environment, the seal further comprising a stiffener, the carrier having a transverse distance between the first and second edge seams on a line perpendicular to the first and second edge seams at a distance midway between the valve end and the insertion end, the carrier further comprising first, second, third, and fourth vertical stability bar welds between the exterior layer and interior layer, each vertical stability bar weld substantially parallel to the first and second edge seams and substantially perpendicular to the valve end, the first vertical stability bar weld disposed one-third the transverse distance from the first edge seam and one-third the transverse distance from the second vertical stability bar weld, the third vertical stability bar weld disposed one-third the transverse distance from the first edge seam and one-third the transverse distance from the fourth vertical stability bar weld, the second vertical stability bar weld disposed one-third the transverse distance from the second edge seam and one-third the transverse distance from the first vertical stability bar weld, the fourth vertical stability bar weld disposed one-third the transverse distance from the second edge seam and one-third the transverse distance from the third vertical stability bar weld.
