It should be noted that there are many options for the connection between the upper sheet 21 and the lower sheet 22, the connection between the upper sheet 21 and the peripheral sheet, and the connection between the lower sheet 22 and the peripheral sheet, for example: stitching or adhesive, etc.
The manufacturing method of the inflatable product 2 provided by the embodiment comprises the following steps: the second adhesive layer is arranged on the upper piece 21 and the lower piece 22, the first adhesive layer is arranged on the first pulling strip piece 11 and the second pulling strip piece 12, then the first adhesive layer of the first pulling strip piece 11 is arranged corresponding to the second adhesive layer of the upper piece 21, the first adhesive layer of the second pulling strip piece 12 is arranged corresponding to the second adhesive layer of the lower piece 22, and then the upper piece 21 and the first pulling strip piece 11, the lower piece 22 and the second pulling strip piece 12 are connected together in a high-frequency or hot-melting mode.
As shown in fig. 3 to 8, the present embodiment provides an inflatable product 2 including: an upper sheet 21, a lower sheet 22 and a draw tape 1; the upper sheet 21 and the lower sheet 22 are provided with second adhesive layers at positions corresponding to the first adhesive layers; the upper piece 21 and the lower piece 22 are oppositely arranged, the first strap drawing piece 11 and the second strap drawing piece 12 are arranged between the upper piece 21 and the lower piece 22, and the upper piece 21 is connected with the first strap drawing piece 11, the lower piece 22 and the second strap drawing piece 12. Set up the second on the corresponding position of layer is pasted with first to upper sheet 21 and lower sheet 22, promptly, upper sheet 21 and lower sheet 22 are the part and set up the second and paste the layer, so, can reduce effectively the utility model provides an aerify product 2's weight and cost.
On the basis of the above embodiment, specifically, the number of the draw tapes 1 is plural, and the plural draw tapes 1 are arranged at intervals between the upper sheet 21 and the lower sheet 22.
Since the pull tapes 1 mainly serve to support and shape, in order to provide the inflatable product 2 of the present embodiment with a more stable shape and less deformation, a plurality of pull tapes 1 are provided at intervals between the upper sheet 21 and the lower sheet 22.
The first drawstring piece 11 and the second drawstring piece 12 of each drawstring 1 are respectively connected with the upper sheet 21 and the lower sheet 22, and the second adhesive layer is only arranged on the upper sheet 21 and the lower sheet 22 at the position connected with the first adhesive layer, and the second adhesive layer is not arranged at other positions, thereby further saving the cost and reducing the weight.
It should be noted that the length of the drawstring 1 may be equal to the length of the upper sheet 21, and certainly may be smaller than the length of the upper sheet 21; as shown in fig. 7, when the length of the pull tape 1 is smaller than the length of the upper sheet 21, the pull tapes 1 may be distributed in an array between the upper sheet 21 and the lower sheet 22, i.e., a plurality of pull tapes 1 are provided in both the length direction and the width direction of the upper sheet 21. Moreover, the pull straps are arranged in the manner shown in fig. 7, so that the production cost and the quality of the inflatable product can be further reduced.
On the basis of the above-described embodiment, specifically, the joining manner between the upper sheet 21 and the first drawstring sheet 11 is point joining, line joining, and/or surface joining; alternatively, the joining between the lower sheet 22 and the second tab 12 may be point, line and/or surface.
The following description will be given by taking as an example only the manner of joining the first drawstring piece 11 and the upper piece 21: as shown in fig. 3, 5, 6, 7, 8, the first tab 11 can be joined to the top panel 21 by only spot, line or surface joining, etc.; a combination of point bonding and wire bonding, a combination of point bonding and surface bonding, or a combination of wire bonding and surface bonding; of course, a combination of point, line, and surface joints is also possible.
It should be noted that, when the lines are selected to be joined, the routing of the first tab 11 and the upper tab 21, and the routing of the second tab 12 and the lower tab 22 may be straight lines, broken lines, or corrugated lines, etc.; the shape of the contact surface between the first tab 11 and the upper piece 21, the second tab 12 and the lower piece 22 when the surfaces are selectively engaged may be circular, oval, square or diamond, etc.
On the basis of the above embodiment, specifically, the upper sheet 21 is made of an elastic fabric.
The elastic fabric of the upper sheet 21 is a fabric having good stretch property and shrinkage property, wherein the elasticity of the fabric can be determined by the stretch property and shrinkage property. There are many options for elastic fabrics, for example: lycra plus material, polyester, nylon, modal or stretch cloth, etc. The upper sheet 21 of the inflatable product 2 provided in this embodiment may use stretch cloth.
When a user sits and lies on the inflatable product 2 provided in the embodiment, the upper sheet 21 usually deforms to some extent due to pressure, and if the upper sheet 21 has poor stretching performance, the upper sheet may break when subjected to a large pressure; if the shrinkage performance is poor, the original shape can not be recovered quickly or quickly after large deformation is generated; all of the above may shorten the life of the inflatable product 2; therefore, the upper sheet 21 is made of the fabric with good tensile property and shrinkage property, so that the upper sheet 21 can be quickly restored to the original shape when being subjected to large pressure, and meanwhile, the upper sheet is not broken.
In addition to the above embodiment, specifically, a fixing piece having elasticity smaller than that of the upper piece 21 is provided on a surface of the upper piece 21 disposed opposite to the lower piece 22.
The fixing piece is provided on an inner surface of the upper sheet 21, that is, a surface of the upper sheet 21 disposed opposite to the lower sheet 22. The fixing sheet is provided to prevent the upper sheet 21 from coming into direct contact with the lower sheet 22 when the pressure applied to the upper sheet 21 is large and the elasticity of the elastic fabric of which the upper sheet 21 is made is good, and therefore, it is required that the elasticity of the fixing sheet is smaller than that of the upper sheet 21, that is, the stretching and shrinking properties of the fixing sheet should be poor compared to the upper sheet 21; thus, the fixing piece with smaller elasticity can play a role of buffering and supporting the upper piece 21. The face fabric for the anchor sheet may be variously selected, for example: nylon, polyester, or scrim, etc.; as long as the elasticity of the fabric of the fixing piece is smaller than that of the upper piece 21.
Attachment of the anchor tab to the top panel 21 can be accomplished in a variety of ways, for example: bonding, sewing, etc.; glue or hot melt adhesive can be used during bonding; specifically, the attachment of the fixing piece to the upper piece 21 may also be spot bonding, line bonding, surface bonding, or the like.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
