It is worth mentioning that, in the utility model, represent the term in orientation, such as " left side "; " right side ", " top ", " bottom "; " top " and " bottom " and approximate term etc. thereof, just describe relativeness, be not limited to protection domain of the present utility model.
That is, the introducing of described folding unit 30, can change the bearing of trend of air chamber, thus provides multiple buffering effect.It is worth mentioning that, in conventional air packaging bag, if an air chamber damages and leaks gas, the air cushioning fruit of the sidewall at this air chamber place will be affected, but, in described spatial folding formula air-packing device of the present utility model, described sub-air chamber 111 when a certain side is damaged, such as, when a certain sub-air chamber 111 of described upper left sidewall 10c is damaged and produces gas leakage, at the left surface that it is same, still the described sub-air chamber 111 of described lower left sidewall 10d is had still to play air cushioning effect, thus the air cushioning performance of the left side sidewall of described spatial folding formula air-packing device is not subject to too large impact.
It is worth mentioning that, because the folding effect of described folding unit 30, and the folding part 31 overlapped each other is together with 32 involutions, thus make the described sub-air chamber 11 of these air chambers 11 in both sides because described folding unit 30 pull effect, also form respectively left side sidewall 10c and 10d, and right sidewall 10e and 10f.
In addition, the setting of described folding unit 30, also plays the effect preventing air from flowing on a large scale.Specifically, in conventional air packaging bag, because an air chamber only extends along a direction in whole conventional air packaging bag, such as extend in a longitudinal direction thus form longitudinal air chamber, when conventional air packaging bag is when being subject to clashing into, air in air chamber can flow along whole longitudinal direction, thus the charge air along air chamber bearing of trend local location can be caused not enough, thus affects the air cushioning effect of whole air chamber.
But, because described spatial folding formula air-packing device of the present utility model is provided with described folding unit 30, the such as described folding unit 30 in left side, so the upper and lower sides in left side form respectively the plenum chamber along horizontal and vertical extension, like this when being subject to impacting, the air of described upper left sidewall 10c because the iris action of described folding unit 30, and is not easy to flow into described lower left sidewall 10d.Similarly, the air of described lower left sidewall 10d is because the iris action of described folding unit 30 is also not easy to flow into described upper left sidewall 10c, thus described folding unit 30 and play the effect preventing air from distributing in different spaces, thus make described upper left sidewall 10c and described lower left sidewall 10d can ensure sufficient charge air, to play preferably air cushioning effect.
In this preferred embodiment of the present utility model, for the left side wall of described spatial folding formula air-packing device, described folding unit 30 can form with described upper left sidewall 10c and described lower left sidewall 10d, that is, can be formed through a series of folding and heat-sealing by same air chamber 11.Particularly, the multiple described air chamber 11 in the left side of described spatial folding formula air-packing device divide into three parts, the multiple described sub-air chamber 111 of downside forms described lower left sidewall 10d, middle multiple described air chamber 111 forms described folding unit 30, and the multiple described sub-air chamber 111 of upside forms described upper left sidewall 10c.The multiple described sub-air chamber 111 of described folding unit 30 has one or more choke seam 105 separately, to reduce the charge air of sub-air chamber 111 described in each, thus make described folding unit 30 be easy to folding relative to described upper left sidewall 10c and described lower left sidewall 10d, thus whole described spatial folding formula air-packing device can be made to produce the change of steric configuration.And in conventional air packaging bag, by arranging bending node, different sidewalls can only be formed, thus also limited around the kind of the shape of the spatial accommodation formed by different lateral.
It is worth mentioning that, the quantity of the choke seam 105 in sub-air chamber 111 described in each of described folding unit 30, shape, size and position are not restricted.Such as, can be along the length direction of air chamber 111 sub-described in each vertically arrange multiple apart from one another by described choke seam 105, but and not exclusively shut described sub-air chamber 111, thus described upper left sidewall 10c still can interconnect with described lower left sidewall 10d.In other variant embodiment, one or more choke seams 105 in sub-air chamber 111 described in each arrange along the direction parallel with the length direction of air chamber 111 sub-described in each apart from one another by ground, thus air chamber 111 sub-described in each is divided into multiple minor diameter plenum chamber further.That is, described folding unit 30 has minor diameter plenum chamber relative to described upper left sidewall 10c and described lower left sidewall 10d, and these minor diameter plenum chambers make described folding unit 30 be easy to folding, as shown in Figure 8 A.It will be appreciated by persons skilled in the art that described choke seam 105 also can have other arrangement and arrangements, only need to reach the charge air that reduces described air-filled foldable unit 30 thus reach and be easy to fold.
In this preferred embodiment of the present utility model, the described folding unit 30 in left side can be positioned at the inner side of described lower left sidewall 10d or described upper left sidewall 10c, namely the inner side of the spatial accommodation that described spatial folding formula air-packing device is formed is positioned at, also can be positioned at the outside of described lower left sidewall 10d or described upper left sidewall 10c, namely be positioned at the outside of described spatial folding formula air-packing device.But because at left direction, described lower left sidewall 10d and described upper left sidewall 10c has plenum chamber, thus does not affect the air cushioning performance of left direction.
The described folding unit 30 on right side and the structure of upper right sidewall 10e and bottom right sidewall 10f and the described folding unit 30 in left side, described upper left sidewall 10c is roughly the same with the structure of described lower left sidewall 10d.Thus make the described spatial folding formula air-packing device in this preferred embodiment of the present utility model form the spatial accommodation 100 of generally rectangular shape.It is worth mentioning that, described upper left sidewall 10c and described upper right sidewall 10e forms the structure comprising two straton air chambers 111 by bending.And unite by a seam respectively by superimposed seam 106 at it.
The spatial folding formula air-packing device of this preferred embodiment of the present utility model is suitable for packing the article described to be packaged with approximate right angle shape, such as in the example shown in figure 2, packet printing machine can be carried out by two described spatial folding formula air-packing devices.The two ends of described chopping machine are positioned in the described spatial accommodation 100 of two described spatial folding formula air-packing devices, and spatial folding formula air-packing device described in each can play the effect of buffer protection respectively to each side at the two ends of chopping machine.The spatial folding formula air-packing device of this preferred embodiment of the present utility model forms the described spatial accommodation 100 of approximate right angle shape, make spatial folding formula air-packing device described in each can fit tightly the two ends in described chopping machine respectively, thus provide preferably air cushioning effect for described chopping machine.And conventional air packaging bag is when packing, and between article to be packaged, form larger space, thus good buffering effect can not be provided.
It is worth mentioning that, after the spatial folding formula air-packing device of this preferred embodiment of the present utility model packages described chopping machine, can be positioned in packing chest or packing box, thus be convenient to transport and store.In addition, the utility model is equivalent to provide a kind of new manner of packing, the spatial folding formula air-packing device of the two ends of described chopping machine with this preferred embodiment of the present utility model is only needed to package, and do not need whole described chopping machine to be placed in an air rubber capsule pack, thus also greatly save packing, reduce packing cost.
In addition, chopping machine recited above just for citing, but does not limit the utility model, and spatial folding formula air-packing device of the present utility model can also be applied to the frangible damageable various described article to be packaged that packaging needs to provide buffering.
The spatial folding formula air-packing device of this preferred embodiment of the present utility model can be prepared in the following way.It can be formed by a series of folding and sealing by the two layers of air cells layer 101 and 102 that superposed arranges.Air chamber layer 101 and 102 described in each can be made up of flexible thin-film material.Its heat-sealing by positions such as local and boundaries forms inflation inlet 13 and filling channel 14, by the heat-sealing along multiple row partitioning slot 103, the inflatable chamber 12 that air chamber layer 101 and 102 is formed is divided into multiple air chamber 11, the heat-sealing of then separating 104 along multiple row forms multiple sidewalls of described spatial folding formula air-packing device, and each air chamber 11 is divided into the sub-air chamber 111 interconnected.Such as, in above preferred embodiment, by first row bending seam 1041, secondary series bending seam 1042, and the 3rd row bending seam 1043 forms described downside wall 10a, rear wall 10b, side wall 10g, and superimposed wall 10h.Described superimposed wall 10h by one or more superimposed seam 106 respectively with described rear wall 10b, upper left sidewall 10c together with described upper right sidewall 10e involution.
In the position of local, by multiple choke seam 105, multiple sub-air chamber 111 adjoined is reduced charge air, thus form folding unit 30, and remaining sub-air chamber 111 forms inflation buffer cell 10.Described folding unit 30 is after folding, then in that one end close to opening by least one location slit 107 involution, the part be namely connected with described inflation buffer cell 10 by described folding unit 30 is by described location slit 107 involution.On of the present utility model in preferred embodiment, form two described folding units 30, thus make described air chamber layer 101 and 102 form upper left sidewall 10c respectively in both sides, lower left sidewall 10d, upper right sidewall 10e and bottom right sidewall 10f.Thus the described inflation buffer cell 10 that described folding unit 30 makes remaining sub-air chamber 111 be formed after folding is produced various space multistory configuration.Also be provided with charge valve 20 in air chamber 11 described in each, it will disclose in the following description further.
As depicted in figure 6b, for the left side of described spatial folding formula air-packing device, after folding unit 30 described in each is folding along fold line 113, its outer side edges 311 and the outer side edges of described lower left sidewall 10d are passed through together with joint close 114 involution, then described folding part 31 and described lower left sidewall 10d pass through location slit 107 together with the involution of described folding part 32, thus maintain described folding unit 30 in collapsed shape, thus described spatial folding formula air-packing device of the present utility model is made to be kept firm spatial configuration.
Described fold line 113 can be that wright has been come by craft, makes it form described folding part 31 and described folding part 32, form described fold line 113 between described folding part 31 and 32 by described folding unit 30 by manual folding mode.
The outer side edges 311 of described folding part 31 together with the outer side edges involution of described lower left sidewall 10d, so just makes the air chamber bearing of trend of described upper left sidewall 10c and described lower left sidewall 10d there occurs change by described joint close 114.By the involution of described location slit 107, make collapsed shape firmly shaping further.Be understandable that, described location slit 107 also can by described lower left sidewall 10d with described folding part 31 together with described rear wall 10b and/or described upper left sidewall 10c involution.
Described upper left sidewall 10c is different with the bearing of trend of the air chamber of described lower left sidewall 10d, thus forms two-stage buffer structure in left side, enhances cushion characteristic.When described spatial folding formula air-packing device falls or is subject to impacting, space suffers oppression instantaneously, and flow at plenum interior and distribute, and because the reinforcement effect of described location slit 107, with the existence of described fold line 113, described upper left sidewall 10c and described lower left sidewall 10d is when being subject to impacting, described folding unit 30 stops the air between described upper left sidewall 10c and described lower left sidewall 10d to distribute, thus make described upper left sidewall 10c and described lower left sidewall 10d keep enough amount of airs respectively, thus the inflation cushion characteristic of described upper left sidewall 10c and described lower left sidewall 10d can not be had influence on.
It is worth mentioning that, size and the position of described folding unit 30 are also determined in the size of described joint close 114 and described location slit 107 and position, thus described upper left sidewall 10c and described lower left sidewall 10d size separately can be regulated as required, thus described upper left sidewall 10c and described lower left sidewall 10d charge air size and size are regulated, thus different buffer structures can be formed in upper left side and lower left side, to provide different multi-buffer effects as required.
In addition, also can arrange at predetermined position and intercept seam 116, form the sub-inflation unit 111 of unaerated at these predetermined positions.Such as, when the upper end of described superimposed wall 10h and described rear wall 10b is superimposed, the one or more described sub-inflation unit 111 of the both sides of the upper end lamination portion of itself and described rear wall 10b can arrange described obstruct seam 116, thus forms the sub-inflation unit 111 of not inflating.Also facilitate described superimposed wall 10h folding with described upper left sidewall 10c and described upper right sidewall 10d corresponding respectively.
