[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] A bag with an inflatable handle, combined Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a bag body 1 and an inflatable handle 2. The bag body 1 includes a first bag wall 11 and a second bag wall 12 that are arranged opposite to each other. The first bag wall 11 and the second bag wall 12 are provided with opposite handle holes 13. The inflatable handle 2 is an air column. The inflatable handle 2 is sandwiched between the first bag wall 11 and the second bag wall 12. Both ends of the inflatable handle 2 are heat-pressed with the first bag wall 11 and the second bag wall 12. Two handle holes 13 protrude from the middle of the inflatable handle 2. The inflatable handle 2 is sandwiched between the first bag wall 11 and the second bag wall 12. The two ends of the inflatable handle 2 are connected to the first bag wall 11 and the second bag wall 12 as a whole by heat-pressing, so that the two ends of the inflatable handle 2, the first bag wall 11 and the second bag wall 12 are attached together, and the inflatable handle 2 is reliably connected. After being squeezed, the gas in the inflatable handle 2 gathers toward the middle of the inflatable handle 2. Since the handle hole 13 does not restrict the inflatable handle 2, the gas in the inflatable handle 2 expands at the handle hole 13, so that two handle holes 13 protrude from the middle of the inflatable handle 2, thereby forming an inflatable bag. The inflatable bag is provided for the user to grasp to realize the function of preventing the hand from being strangled, and the inflatable bag does not need to be inflated by adding an inflating nozzle. Because the inflatable bag is formed after being squeezed, it is ensured that the shape of the inflatable bag matches the shape of the handle hole 13, and no thin strip structure is left to cause strangulation. The advantage of the inflatable handle 2 being an air column is that it is easy to manufacture by hot pressing, and the bag body 1 is easy to be hot pressed and formed by the first bag wall 11 and the second bag wall 12, so the bag is easy to be manufactured by automation. In addition, the connection between the inflatable handle 2 and the first bag wall 11 and the second bag wall 12, and the formation of the bag body 1 by the first bag wall 11 and the second bag wall 12 can be hot pressed and formed at one time, which can simplify the manufacturing process. In summary, the bag is suitable for mass production and can reduce the cost of the bag.
[0027] Specifically, O-shaped sealing rings are provided at the hot pressing points between the inflatable handle 2 and the first bag wall 11, and at the hot pressing points between the inflatable handle 2 and the second bag wall 12. The O-shaped sealing rings are formed by hot pressing. The O-shaped sealing rings prevent the gas in the inflatable bag from leaking easily and can reinforce the hot pressing points.
[0028] Preferably, the air column is made of a composite film that is folded in half and then heat-pressed. During the folding and heat-pressing process, air remains in the air column without the need for inflation. The amount of air in the air column ensures that the pressure in the inflatable bag meets the specified value requirement, thereby eliminating the inflation nozzle structure and simplifying the manufacturing process.
[0029] Specifically, three heat-pressing strips are arranged at intervals in the middle of the inflatable handle 2. The heat-pressing strips are arranged along the radial direction of the inflatable handle 2 and the length of the heat-pressing strips is less than or equal to the radius of the inflatable handle 2, that is, heat pressing is performed in the middle of the inflatable handle 2 along the radial direction of the inflatable handle 2. The three heat-pressing strips divide the inflatable bag into four interlinked sections. The four sections cooperate with the fingers to reduce the pressure on the fingers caused by the inflatable handle 2. The three heat-pressing strips can also strengthen the inflatable handle 2 and reduce the deformation of the inflatable bag; at the same time, they can reduce the channel area for gas circulation in the inflatable bag, weaken the flow of gas, and prevent the inflatable bag from having a thin strip structure due to a large amount of gas flowing to both sides after the inflatable bag is squeezed.
[0030] Preferably, the composite film used for the inflatable handle 2 is at least three layers to ensure the strength of the inflatable handle 2. The two outer layers are the handle heat-sealing layers 3, which facilitates the thermal compression of the composite film after folding and the thermal compression of the inflatable handle 2 with the first bag wall 11 and the second bag wall 12 after forming.
[0031] Specifically, the middle of the composite film of the inflatable handle 2 is blank or printed, and it can be selected whether to print according to needs.
[0032] Preferably, the two ends of the inflatable handle 2 are flush with the two sides of the first bag wall 11, that is, the length of the inflatable handle 2 is equal to the width of the first bag wall 11, so as to increase the connection area between the inflatable handle 2 and the first bag wall and the second bag wall, and improve the stability of the connection between the inflatable handle 2 and the first bag wall and the second bag wall.
[0033] Preferably, the handle hole 13 is a "U"-shaped notch, and the inflatable handle 2 is arranged along the opening edge of the "U"-shaped notch, that is, the inflatable handle 2 covers the opening part of the "U"-shaped notch; when the user lifts the bag, the hand passes through the "U"-shaped notch and grasps the inflatable bag.
[0034] Preferably, the first bag wall 11 and the second bag wall 12 both include a pressing area 14 , and the pressing area 14 of the first bag wall 11 and the second bag wall 12 are heat-pressed together, and the handle hole 13 is located in the pressing area 14 , and the handle hole 13 is reinforced around to further ensure the stability of the inflatable handle 2 .
[0035] Preferably, the pressing area 14 is "U"-shaped, so that the first bag wall 11 and the second bag wall 12 form a containing space for containing objects, and an opening is formed at one end away from the handle hole 13 to load the objects. After the objects are loaded, the opening is sealed by heat pressing to realize the packaging of the bag for the objects.
[0036] Preferably, the first bag wall 11 and the second bag wall 12 are both made of a composite film, and the composite film used in the first bag wall 11 and the second bag wall 12 is at least two layers to ensure the strength of the bag body 1. In addition, the bag wall heat-sealing layer 3 is provided on the opposite sides of the first bag wall 11 and the second bag wall 12, which is used for heat pressing between the first bag wall 11 and the second bag wall 12, between the first bag wall 11 and the inflatable handle 2, and between the second bag wall 12 and the inflatable handle 2.
[0037] Specifically, the outer layer of the composite film of the first bag wall 11 and the second bag wall 12 is a blank layer or a printed layer, and it can be selected whether to print according to demand.
[0038] The manufacturing process of a bag with an inflatable handle disclosed in the present application is as follows:
[0039] First, the composite film used to manufacture the bag body 1 is cut into the shapes of the first bag wall 11 and the second bag wall 12 , and the composite film used to manufacture the inflatable handle 2 is cut into strips.
[0040] Secondly, the strip-shaped composite film is folded in half and then heat-pressed to form a tubular structure, which is convenient for continuous processing of the inflatable handle 2.
[0041] Next, the two ends of the tubular structure of corresponding length are heat pressed together to form an air column according to the width of the first bag wall 11. The tubular structure can be inflated during pressing to ensure that the amount of air in the air column can make the air column after extrusion reach a specified air pressure range.
[0042] Then, the air column is placed between the first bag wall 11 and the second bag wall 12, and the first bag wall 11 and the second bag wall 12 are gradually heat-pressed from both sides to the middle, so that the air in the air column gradually gathers in the middle. The pressing area 14 is then heat-pressed into one, forming a storage space for containing objects.
[0043] Finally, after the objects are put into the bag, the bag opening is sealed by heat compression to complete the packaging of the objects.
[0044] The manufacturing process of the bag with the inflatable handle is mostly conventional cutting, folding and heat pressing, the manufacturing process is simple, and it is convenient for mass production, which can reduce the cost of the bag.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
