Description

Technical Field

[0001] The present application relates to the field of aluminum foil composite bags, and in particular to a high-temperature resistant aluminum foil composite bag. Background Art

[0002] Composite aluminum foil bags are bags made by compounding and combining multiple plastic films and then passing through a bag making machine. They are used to package food, pharmaceutical industrial products, daily necessities, etc. Aluminum foil bags are also called pure aluminum bags. Composite aluminum foil bag packaging usually refers to aluminum-plastic composite vacuum packaging bags. This type of product is suitable for moisture-proof, light-proof, and vacuum packaging of large-scale precision machinery and equipment, chemical raw materials, and pharmaceutical intermediates. It mostly adopts a four-layer structure and has good water-proof and oxygen-proof functions. It is not restricted and can be customized to different specifications and styles of packaging bags. It can be made into flat bags, three-dimensional bags, accordion bags and other styles. Common aluminum foil bags generally have anti-gloss properties on their surface, which means that they do not absorb light, and are made of multiple layers. Therefore, aluminum foil has both good light-shielding properties and strong isolation properties, and because it contains aluminum, it also has good oil resistance and softness.

[0003] With reference to the Chinese patent application with publication number CN220843638U, an improved composite aluminum foil bag is disclosed, including a bag body, which is the outer shell of the composite aluminum foil bag, and protective strips are provided at the outer corners thereof, slots are provided on the sides of the protective strips, adhesive patches are attached to the inner walls of the slots, and adhesive patches are attached to the corner surfaces of the bag body. During the use of the aluminum foil bag, the contact wear between the corners and objects will be protected by the various protective strips, so that the service life of the aluminum foil bag is not easily reduced due to contact wear of the corners. The polyurethane coating can improve the tear resistance and wear resistance of the bag surface. At the same time, the polyester film can also improve the wear resistance of the aluminum foil bag, and can also resist tearing and puncture, so that the aluminum foil bag is not easily cut or worn directly when hit by sharp objects, avoiding contamination or damage to the items in the package.

DETAILED DESCRIPTION

[0022] Based on this, in order to improve the problem that the composite aluminum foil bag in the related art has poor heat resistance during use, if high-temperature items are placed inside, the composite aluminum foil bag may be damaged. At the same time, the composite aluminum foil bag decomposes due to heat, which may affect the quality of the internal items and even burn the user. The embodiment of the present application provides the following solution.

[0023] See also Figures 1 to 4 A high-temperature resistant aluminum foil composite bag includes a bag body 1, a composite structure 2, a lifting mechanism 3 and a supporting component 7. The composite structure 2 is used to improve the thermal insulation, heat resistance and tensile strength of the bag body 1. The lifting mechanism 3 is used to carry the bag body 1, and the supporting component 7 is used to maintain the stability of the bag body 1 when placed.

[0024] See also Figures 1 to 4 The composite structure 2 includes an aluminum foil layer 21, a polymer layer 22, a heat-insulating layer 23 and a high-temperature resistant coating 24. The aluminum foil layer 21 is bonded and fixed on the inner surface of the bag body 1, and the polymer layer 22 is bonded and fixed on the side of the aluminum foil layer 21 away from the inner surface of the bag body 1. The heat-insulating layer 23 is bonded and fixed on the polymer layer 22, and the high-temperature resistant coating 24 is fixedly bonded on the heat-insulating layer 23. The lifting mechanism 3 is used to lift the bag body 1. The bottom of the bag body 1 is fixedly connected to a support plate 6, and a support component 7 is provided on the support plate 6. The support component 7 includes a fixed shaft 71, a slider 72, and a connecting rod. The connecting rod 73 and the movable plate 74, the fixed shaft 71 is fixedly connected to the support plate 6, the connecting rod 73 is rotatably connected to the fixed shaft 71, the slider 72 is fixedly connected to the two ends of the connecting rod 73, and a slide groove 8 is provided on the movable plate 74, the slider 72 is slidably connected in the slide groove 8, and the movable plate 74 is fixedly connected to the two ends of the connecting rod 73 through the slider 72, and the movable plate 74 is also provided with anti-slip grooves 9, and the anti-slip grooves 9 are evenly opened on the lower surface of the movable plate 74, the polymer layer 22 is made of polyethylene material, and the thermal insulation layer 23 is made of polyurethane material.

[0025] With such arrangement, when putting items into the bag body 1, the user pulls the movable plate 74 toward the two sides of the bag body 1. At this time, the slider 72 located in the slide groove 8 of the movable plate 74 begins to move along the direction of the slide groove 8 toward the two ends of the slide groove 8, thereby driving the connecting rod 73 set between the movable plates 74 to rotate around the fixed axis 71. When the connecting rod 73 is perpendicular to the movable plate 74, stop pulling the movable block, clamp the connecting rods 73, and then place the bag body 1 to open the delivery port of the bag body 1, and place the items into the bag body 1.

[0026] The effect of such arrangement is that, by arranging the aluminum foil layer 21, the isolation and moisture-proof and anti-oxidation properties of the bag body 1 are improved; by arranging the polymer layer 22, the tensile strength and heat-sealing ability of the bag body 1 are improved; by arranging the heat insulation layer 23, the heat insulation ability of the bag body 1 is improved, thereby preventing the high temperature of the items inside the bag body 1 from scalding the user; by arranging the high-temperature resistant coating 24, the high-temperature resistance of the bag body 1 is enhanced, ensuring that the bag body 1 is not easily deformed or damaged in a high-temperature environment, thereby preventing the bag body 1 from being damaged due to high temperature, causing the items inside the bag body 1 to fall and cause damage to the items; by the mutual cooperation of the movable plate 74, the slider 72, the connecting rod 73 and the fixed shaft 71, the packaging paper bag is more stable when placed in different environments, thereby ensuring the quality of the items in the bag body 1; by providing the anti-slip groove 9 on the movable plate 74, the friction between the bottom of the bag body 1 and the desktop is increased.

[0027] See also Figures 1 to 4 The lifting mechanism 3 includes a shoulder strap 31, a buckle 32 and a clamping plate 33. The buckle 32 is fixedly connected to the side of the bag body 1, and the clamping plate 33 is rotatably connected to the buckle 32. One end of the shoulder strap 31 is fixedly connected to the side of the bag body 1 symmetrical to the buckle 32, and the other end of the shoulder strap 31 is clamped with the buckle 32. A plurality of clamping spikes 4 are evenly arranged on the end of the shoulder strap 31 close to the buckle 32. The shoulder strap 31 is clamped with the buckle 32 through the clamping spikes 4. A shoulder pad 5 is also provided on the shoulder strap 31.

[0028] When the shoulder strap 31 is adjusted, the user can hang the shoulder strap 31 on the shoulder to carry the bag 1.

[0029] The effect of such a setting is that, through the cooperation of the shoulder strap 31, the buckle 32, the card plate 33 and the thorn 4, when the arms become weak after carrying the packaging paper bag for a long time, the user can hang the shoulder strap 31 on the shoulder to carry the packaging paper bag, which saves the user's physical energy and increases the practicality of the packaging paper bag. In addition, users of different heights can adjust the length of the shoulder strap 31 by moving the position where the card plate 33 is connected to the thorn 4. At the same time, a shoulder pad 5 is set on the shoulder strap 31 to increase the contact area between the shoulder strap 31 and the shoulder, thereby reducing the squeezing feeling of the shoulder strap 31 on the user's shoulder.

[0030] From the above, we can see that the working principle of this application is as follows:

[0031] When putting items into the bag body 1, the user pulls the movable plate 74 toward both sides of the bag body 1. At this time, the sliders 72 located in the chute 8 of the movable plate 74 begin to move along the direction of the chute 8 toward the two ends of the chute 8, thereby driving the connecting rod 73 arranged between the movable plates 74 to rotate around the fixed axis 71. When the connecting rod 73 is perpendicular to the movable plate 74, the user stops pulling the movable block, and the connecting rods 73 are engaged. Then, the bag body 1 is placed in the opening of the bag body 1, and the items are placed into the bag body 1.

[0032] When the user's arms become weak while carrying the bag body 1, the user can adjust the length of the shoulder strap 31 set on the bag body 1 according to his or her height. During the adjustment process, the card plate 33 on the buckle 32 is first raised by the rotating shaft, and then the end of the shoulder strap 31 close to the buckle 32 is inserted into the gap between the buckle 32 and the card plate 33. At this time, the shoulder strap 31 placed in the gap between the buckle 32 and the card plate 33 is moved up or down. When the shoulder strap 31 is moved to the appropriate position, the card plate 33 is engaged with the buckle 32. Since a card thorn 4 is provided on the end of the shoulder strap 31 close to the buckle 32, the shoulder strap 31 placed between the buckle 32 and the card plate 33 will be fixed, thereby changing the length of the shoulder strap 31. When the shoulder strap 31 is adjusted, the user hangs the shoulder strap 31 on the shoulder to carry the bag body 1.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
