Abstract
An air bag packaging arrangement and a self-adhesive checking valve, the air bag packaging arrangement includes an air bag and an air valve which is the self-adhesive checking valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a strengthening film provided between the first valve film and the first cell film to strengthen a joint strength between the first valve film and the first cell film, so as to prevent the first valve film from being broken, so as to further avoid an air leakage.
Claims30
An air bag packaging arrangement, comprising:
- an inflatable body comprising a first cell film and a second cell film, wherein said first cell film and a second cell film overlap with each other, so as to form at least one inflatable unit, wherein each said inflatable unit has an inflatable air chamber;
- and
- an air valve comprising a first valve film, a second valve film and a strengthening film, wherein said first valve film, said second valve film and said strengthening film overlap with each other, wherein said first valve film, said second valve film, said strengthening film, said first cell film and said second cell film are heat-sealed to form at least one air entering channel between said first valve film and said second valve film, wherein said at least one air entering channel is used to inflate said inflatable air chamber, wherein when an inflating process is finished, said first valve film and said second valve film attach to said second cell film, so as to close said air entering channel, so as to realize a self-sealing effect, wherein said strengthening film is provided between said first valve film and said first cell film to strengthen a joint strength between said first valve film and said first cell film, so as to prevent said first valve film from being broken, so as to further avoid an air leakage.
An air valve, which is suitable to inflate an air bag packaging arrangement comprising an inflatable body, wherein the inflatable body comprises two cell films overlapping with each other to form at least one inflatable unit, wherein each the inflatable unit has an inflatable air chamber, wherein said air valve comprises two valve films overlapping with each other and a strengthening film, wherein said two valve films, said strengthening film and the two cell films are heat-sealed, so as to form at least one air entering channel between said two valve films, which is used to inflate the inflatable air chamber, wherein after an inflating process is finished, said first and second valve films attach to one of the two cell films, so as to close said at least one air entering channel, wherein said strengthening film is provided between the other cell film and one of said two valve films.
A manufacturing method of an air bag packaging arrangement, comprising the following steps:
- (a) overlapping five films together, wherein a first film and a fifth film respectively form a first cell film and a second cell film, wherein a third film and a fourth film respectively form a first valve film and a second valve film, wherein a second film forms a strengthening film, wherein a heat-resisting separating layer is provided between said first valve film and said second valve film;
- and
- (b) forming an inflatable body by said five films which has one or more inflatable units which are inflated and able to store gas via a heat-sealing step, wherein said first cell film, said strengthening film and a proximate end of said first valve film are heat-sealed together by a plurality of sealing seams, wherein said second cell film and a proximate end of said second valve film are heat-sealed together, so as to form at least one air entering channel between said first valve film and said second valve film, wherein when a pressure of an inflatable air chamber of said inflatable unit reaches to a predetermined value, said first valve film and said second valve film attach to said second valve film, so as to close said at least one air entering channel, wherein said strengthening film strengthens a connection strength between said first cell film and said first valve film, so as to prevent said first valve film from being broken.
