Description

Technical Field

[0001] This utility model relates to the field of aluminum foil bag technology, and in particular to self-sealing aluminum foil bags. Background Technology

[0002] Aluminum foil bags, also known as pure aluminum bags, typically refer to aluminum-plastic composite vacuum packaging bags. These products are suitable for moisture-proof, light-proof, and vacuum packaging of large precision machinery, chemical raw materials, and pharmaceutical intermediates. They often employ a four-layer structure, providing excellent water and oxygen barrier properties. Applications include packaging for various circuit boards, electronic products, precision machinery parts, consumer goods, and industrial products; and food packaging such as milk, rice, meat products, dried fish, aquatic products, preserved meats, roast duck, and roast chicken.

[0003] Existing technologies, such as the utility model patent with publication number CN214550267U, disclose a self-sealing aluminum foil bag for pharmaceutical packaging. This patent uses an aluminum foil bag as a first body, and both the first and second bodies of the aluminum foil bag have sealing ends on their upper surfaces. The first body of the aluminum foil bag has a first observation window end, which is integrally formed with the first body of the aluminum foil bag. The second body of the aluminum foil bag has a second observation window end, which is integrally formed with the second body of the aluminum foil bag. This utility model device solves the problem that most existing aluminum foil bags used for pharmaceutical packaging cannot expel internal air according to the user's needs, resulting in a shortened shelf life of the tablets.

[0004] The inventors discovered in their daily work that users often find it difficult to quickly close the opening device when using the equipment, resulting in time-consuming and laborious use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where users find it difficult to quickly close the opening device, and to propose a self-sealing aluminum foil bag.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-sealing aluminum foil bag, comprising an aluminum bag and a sealing device, wherein a connecting strap is provided on the side of the aluminum bag, an opening device is provided on the surface of the connecting strap, and a bag opening is provided at one end of the connecting strap; the sealing device is installed on the surface of the opening device, and the sealing device includes a connecting block and a sliding plate; the connecting block is fixedly connected to the surface of the opening device, and the sliding plate is slidably connected to the surface of the opening device; a slot is provided on the upper surface of the connecting block, and a pull hole is provided on the inner wall of the sliding plate; a pull rod is slidably connected to the inner wall of the pull hole.

[0007] Furthermore, a stop block is fixedly connected to the surface of the pull rod, and one end of the pull rod is engaged with the inner wall of the slot. By setting the pull rod, the slide plate can be restricted, reducing the possibility that the slide plate will easily slide freely on the surface of the opening device during use.

[0008] Furthermore, a first spring is sleeved and connected to the surface of the pull rod. The two ends of the first spring are fixedly connected to the surface of the abutment block and the inside of the pull hole, respectively. The first spring is provided to facilitate the application of a restoring force to the pull rod.

[0009] Furthermore, a pull plate is fixedly connected to the end of the pull rod away from the slot, and the pull plate is provided to facilitate the movement of the pull rod.

[0010] Furthermore, one end of the connecting belt is provided with an exhaust device, which includes an exhaust pipe and an exhaust hole. The exhaust pipe is fixedly connected to the interior of the connecting belt, and the exhaust hole is provided with the interior of the exhaust pipe. A connecting frame is fixedly connected to the inner wall of the exhaust pipe, and a connecting plate is fixedly connected to one end of the exhaust pipe. A sliding rod is slidably connected to the inner wall of the connecting frame, and a retaining ball is fixedly connected to one end of the sliding rod. By setting the retaining ball, the exhaust hole can be blocked, reducing the possibility of air inside the aluminum bag exchanging freely with the outside air during use.

[0011] Furthermore, the ball abuts against the inner wall of the vent hole, and a slider is fixedly connected to the end of the slide rod away from the ball. The slide rod is provided to facilitate limiting the movement of the ball.

[0012] Furthermore, a second spring is fixedly connected to the end of the slider away from the slide rod, and the end of the second spring away from the slider is fixedly connected to the surface of the connecting plate. The second spring is provided to facilitate the application of a reset force to the slider.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when using the device, the user places the items to be packed into the aluminum bag and seals them. When using the device, the user pulls the pull plate, which moves the pull rod, which in turn moves the stop block. The stop block then causes the first spring to deform and generate elastic force, causing the pull rod to move out of the slot. The sliding plate then loses its restraint and moves to close the opening device. By setting up the sealing device, the opening device is effectively sealed, achieving the effect of quickly sealing the opening device. This reduces the difficulty for the user in quickly closing the opening device during use, thus reducing the time and effort required for the user and improving the practicality of the device.

[0015] 2. In this utility model, by setting up an exhaust device, when the user presses the aluminum bag, the air inside the aluminum bag moves the locking ball. When the locking ball moves, it drives the sliding rod to move, which in turn drives the slider to move. When the slider moves, it causes the second spring to deform and generate elastic force. Then, the locking ball disengages from one end of the exhaust hole, releasing the air inside the aluminum bag. By setting up an exhaust device, the air inside the aluminum bag is effectively discharged, reducing the possibility of contamination of the contents of the aluminum bag due to the difficulty in releasing air during use, thus improving the practicality of the equipment.

A connecting strap 1 is provided on the side of the aluminum bag 2, an opening device 3 is provided on the surface of the connecting strap 1, and a bag opening 4 is provided at one end of the connecting strap 1.

[0023] The specific settings and functions of the edge sealing device 5 and the exhaust device 6 will be explained in detail below.

[0024] In this embodiment: the edge sealing device 5 is installed on the surface of the opening device 3. The edge sealing device 5 includes a connecting block 51 and a sliding plate 52. The connecting block 51 is fixedly connected to the surface of the opening device 3, and the sliding plate 52 is slidably connected to the surface of the opening device 3. The upper surface of the connecting block 51 is provided with a slot 53, and the inner wall of the sliding plate 52 is provided with a pull hole 54. A pull rod 55 is slidably connected to the inner wall of the pull hole 54.

[0025] Specifically, a stop block 56 is fixedly connected to the surface of the pull rod 55, and one end of the pull rod 55 is engaged with the inner wall of the slot 53.

[0026] In this embodiment, by setting the pull rod 55, the slide plate 52 can be restricted, reducing the possibility that the slide plate 52 will easily slide freely on the surface of the opening device 3 during use.

[0027] Specifically, a first spring 57 is sleeved and connected to the surface of the pull rod 55. The two ends of the first spring 57 are fixedly connected to the surface of the abutment block 56 and the inside of the pull hole 54, respectively. The first spring 57 is provided to facilitate the application of a restoring force to the pull rod 55.

[0028] Specifically, a pull plate 58 is fixedly connected to the end of the pull rod 55 away from the slot 53. The pull plate 58 is provided to facilitate the movement of the pull rod 55.

[0029] In this embodiment: one end of the connecting belt 1 is provided with an exhaust device 6, which includes an exhaust pipe 61 and an exhaust hole 62. The exhaust pipe 61 is fixedly connected to the inside of the connecting belt 1. The exhaust hole 62 is opened to provide the interior of the exhaust pipe 61. A connecting frame 63 is fixedly connected to the inner wall of the exhaust pipe 61. A connecting plate 64 is fixedly connected to one end of the exhaust pipe 61. A sliding rod 66 is slidably connected to the inner wall of the connecting frame 63. A retaining ball 65 is fixedly connected to one end of the sliding rod 66.

[0030] In this embodiment, by setting the locking ball 65, the exhaust hole 62 can be blocked, reducing the occurrence of air inside the aluminum bag 2 being randomly exchanged with the outside air during use.

[0031] Specifically, the ball 65 abuts against the inner wall of the vent 62, and a slider 67 is fixedly connected to the end of the slide rod 66 away from the ball 65. The slide rod 66 is provided to facilitate limiting the movement of the ball 65.

[0032] Specifically, a second spring 68 is fixedly connected to the end of the slider 67 away from the slider 66. The end of the second spring 68 away from the slider 67 is fixedly connected to the surface of the connecting plate 64. The second spring 68 is provided to facilitate the application of a reset force to the slider 67.

[0033] Working principle: When using the equipment, the user places the items to be packed into the aluminum bag 2 and seals the items. When using the equipment, the user pulls the pull plate 58. When the pull plate 58 moves, it drives the pull rod 55 to move. When the pull rod 55 moves, it drives the stop block 56 to move. When the stop block 56 moves, it causes the first spring 57 to displace and deform, generating elastic force. Then the pull rod 55 moves and disengages from the inside of the slot 53. Then the sliding plate 52 is unrestrained and moves to close the opening device 3. By setting the sealing device 5, the opening device 3 is effectively closed, which plays a role in quickly sealing the opening device 3. This reduces the difficulty for the user to quickly close the opening device 3 during use, which causes time and effort for the user, and improves the practicality of the equipment.

[0034] When using the device, the user presses the aluminum bag 2, causing the air inside the aluminum bag 2 to move the locking ball 65. When the locking ball 65 moves, it drives the sliding rod 66 to move, which in turn drives the slider 67 to move. When the slider 67 moves, it causes the second spring 68 to deform and generate elastic force. Then, the locking ball 65 disengages from one end of the exhaust port 62, releasing the air inside the aluminum bag 2. By setting the exhaust device 6, the air inside the aluminum bag 2 is effectively discharged, reducing the possibility of air being difficult to expel and contaminating the items inside the aluminum bag 2 during use, thus improving the practicality of the device.
