Abstract
An inflation bag with protective base is provided. Two outer films and two inner films are stacked with each other, and the stacked structure is heat sealed and inflated to form the inflation bag. The inflation bag includes two side surface walls and a bottom surface wall between the side surface walls and connected to bottoms of the side surface walls. The bottom surface wall includes bottom columns. Each bottom column has a first bottom column portion, a protection column portion, and a second column portion. A first heat-seal node is provided for attaching the outer films with the inner films, and the first bottom column portion is connected to the second bottom column portion. One or more second heat-seal nodes are provided on the protection column portion for attaching the outer films with the inner films, and the protection column portions are folded to form a protective base.

DETAILED DESCRIPTION
(8) Please refer to
(9) In one embodiment, two outer films 1a and two inner films 1b in the outer films are firstly stacked with each other to form a stacked structure, and then the heat-sealing techniques and inflation are applied to the stacked structure to form the inflation bag with protective base. As shown in
(10) The side surface walls 11 are opposite to each other. Each of the side surface walls 11 comprises a plurality of sidewall columns 111. The bottom surface wall 12 is located between the side surface walls 11 and connected to bottoms of the side surface walls 11. The bottom surface wall 12 comprises a plurality of bottom columns 121. Each of the bottom columns 121 sequentially has a first bottom column portion 1211, a protection column portion 1212, and a second bottom column portion 1213. A first heat-seal node 122 is provided for attaching the outer films with the inner films, so that the first bottom column portion 1211 is connected to the second bottom column portion 1213. At least one second heat-seal node 123 is provided on the protection column portion 1212 for attaching the outer films with the inner films, so that the protection column portions 1212 of the bottom columns 121 are folded to form a protective case 13. As compared with a gas bag known to the inventor(s) in which the base is manufactured by attaching two inner films with each other having insufficient structural strength and difficult and time-consuming manufacturing processes, the inflation bag 1 according to one or some embodiments of the instant disclosure has a greater structural strength, proper supporting ability, and reduced manufacturing processes.
(11) In the embodiments shown in
(12) Please refer to
(13) As shown in
(14) As shown in
(15) In other words, in this embodiment, the flat portion 152 can be adapted to fit over the delivery object. Moreover, because the limiting columns 151 have bulkier sizes than the flat portion 152, the delivery object can be limited within the limiting space S2. Please refer to
(16) Please refer to
(17) According to one or some embodiments of the instant disclosure, during the transportation of the objects, if the objects falls off the ground unintentionally, the inflation bag provides at least two different ways for achieving cushioning and shockproof for the objects; that is, the cushioning and shockproof function provided by the protective base and the side surface walls. In some embodiments, the inflation bag further comprises the cushioning film or further comprises the limiting gas bag which is adjacent to the object to be delivered. Hence, another cushioning and shockproof function can be provided for the object; in other words, in these embodiment, the inflation bag provides at least three different ways for achieving cushioning and shockproof for the objects.
(18) Moreover, as compared with a gas bag known to the inventor(s) in which the base is manufactured by attaching two inner films with each other having insufficient structural strength and difficult and time-consuming manufacturing processes, the inflation bag according to one or some embodiments of the instant disclosure has a greater structural strength, proper supporting ability, and reduced manufacturing processes. Therefore, the aforementioned problem(s) can be improved.
