Abstract
Abstract A vacuum packaged flotation device is provided comprising the combination of an inflatable flotation device, equipment for inflating the flotation device which comprises a valve, a container for holding an inflating medium and the inflating medium, and a sealed vacuum package containing the inflatable flotation device and the equipment for inflating same, which is provided with at least one device for automatically or manually, actuating the inflation of the flotation device; wherein the inflation of the flotation device is triggered by a pull force which acts either automatically or manually on one or more connecting lanyards which are attached at one end to the actuation device, which lanyards extend through the vacuum package in such a manner as to preserve the integrity of the vacuum seal, while at the same time allowing the manual triggering of the actuation device with the exertion of a pull force of no more than about 7-15 Kg from any of a plurality of angles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A vacuum packed inflatable flotation assembly comprising: an inflatable flotation device; means for inflating said inflatable flotation device including a container holding an inflating medium; actuation means for triggering inflation of said inflatable flotation device with said inflating medium; a sealed, flexible vacuum bag containing said inflatable flotation device, said container, and said actuation means, said bag including a neck portion extending therefrom; a pull handle positioned within said neck portion, said pull handle including a hand hole extending therethrough; a weld within said neck portion forming a closed loop within said hand hole; an opening within said weld and extending through said neck portion; and connecting means connecting said pull handle to said actuation means.
Claim 2
Dependent Claim
116 words
A vacuum packed inflatable flotation assembly comprising: an inflatable flotation device; means for inflating said inflatable flotation device including a container holding an inflating medium; actuation means for triggering inflation of said inflatable flotation device with said inflating medium; a sealed, flexible vacuum bag containing said inflatable flotation device, said container, and said actuation means, said bag including a neck portion extending therefrom; a pull handle positioned within said neck portion, said pull handle including a hand hole extending therethrough; a weld within said neck portion forming a closed loop within said hand hole; an opening within said weld and extending through said neck portion; and connecting means connecting said pull handle to said actuation means.
Claim 3
Dependent Claim
54 words
A vacuum packaged inflatable flotation assembly according to claim 1 including two lanyards, said actuation means including a dual actuation head affixed to the container holding the inflating medium, one of said lanyards connecting said pull handle with said actuation means, the other of said lanyards connecting said connector loop with said actuation means.
Claim 4
Dependent Claim
21 words
An assembly as defined in claim 1 wherein said neck portion forms a pair of acute angles with said vacuum bag.
Claim 5
Dependent Claim
21 words
An assembly as defined in claim 1 including a line of weakness formed within said bag and across said neck portion.
Claim 6
Dependent Claim
44 words
A vacuum packaged inflatable flotation assembly according to claim 4, wherein said neck portion is a "T" shaped neck and said acute angles extend at about 15° to about 45° with relation to the axis of the line of weakness across said neck portion.
Claim 7
Dependent Claim
31 words
A vacuum packaged inflatable flotation assembly according to claim 5 wherein said acute angles are about 38° with relation to the axis of the line of weakness across said neck portion.
Claim 8
Dependent Claim
32 words
An assembly as defined in claim 1 wherein said actuation means triggers inflation of said inflatable flotation device in concert with the rupturing of said vacuum bag upon pulling said pull handle.
Claim 9
Dependent Claim
40 words
An assembly as defined in claim 7 wherein a pull force of between 7-15 kg is required to rupture said vacuum bag upon pulling said pull handle from any of a plurality of angles with respect to said vacuum bag.
Claim 10
Dependent Claim
68 words
An assembly as defined in claim 1 including a second neck portion extending from said vacuum bag, a connector loop positioned within said neck portion, a weld within said neck portion forming a closed loop within said connector loop, an opening within said weld with said second neck portion and extending through said second neck portion, and second connecting means connecting said connector loop and said actuation means.
