Abstract
Description
Technical Field
[0001] This invention belongs to the field of packaging products and relates to a sealed zipper bag. Background Technology
[0002] Child safety packaging bags are designed to protect children from accidental ingestion or contact with hazardous substances such as medicines and chemicals. In the past, accidents involving children accidentally ingesting medicines and coming into contact with hazardous chemicals were frequent, posing a threat to children's safety. Therefore, many countries have taken measures requiring the use of child safety packaging bags for medicines and chemicals. These bags employ special designs and opening mechanisms, such as child-proof zippers, twist-top lids, and double locks, making them difficult for children to open or unlock, thus reducing the risk of accidental ingestion or contact with hazardous substances. In addition, child safety packaging bags are usually equipped with clear warning labels to remind guardians to remain vigilant. While child safety packaging bags play a positive role in protecting children's safety, they also have some drawbacks. On the one hand, the complex design of these bags may make them difficult for the elderly or people with hand disabilities to open, causing inconvenience to certain groups; on the other hand, the cost of child safety packaging bags is relatively high, which may increase the price of products. Therefore, there is still room for improvement in the design and cost of child safety packaging bags.
[0003] To address the aforementioned issues, patent CN110194319B discloses a child-proof safety zipper bag. This bag is assembled by the interlocking teeth of two connecting strips, which restricts the movement between the two zipper straps and prevents the bag from opening due to slippage between the two zipper straps. However, this packaging bag is still highly likely to be opened by older children with independent movement and thinking abilities.
[0004] Therefore, there is an urgent need to develop a type of packaging bag that children will not easily open in order to protect them from harm by dangerous items. Summary of the Invention
[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide a sealed zipper bag.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0007] A sealed zipper bag includes a front panel and a back panel connected to form a bag-like structure, and also includes one or more zippers, one snap button, and two pistons;
[0008] The zipper is positioned horizontally between the front and back panels, and the snaps are located on the front side of the front panel.
[0009] Each zipper includes a front zipper and a rear zipper. The middle of the front zipper is fixedly connected to the snap fastener via a connector. The left and right ends of the front zipper and the snap fastener are slidably connected to the front panel. The sliding is synchronous and the sliding direction is up and down. The rear zipper is fixedly connected to the rear panel. The front panel has a strip hole through which the connector passes when it slides with the front zipper and the snap fastener.
[0010] Two pistons are inserted into the bag-shaped structure from the left and right sides respectively and are sealed to it; the two pistons are used to prevent the left and right ends of the front chain belt from sliding downward.
[0011] To open the sealed zipper bag of this invention, two steps are required: first, pull out the piston; second, slide the snaps downwards to separate the front and rear zipper straps. This double safety feature increases the difficulty for children to open the bag, preventing older children with independent action and thinking abilities from opening it.
[0012] As a preferred technical solution:
[0013] As described above, a sealed zipper bag has two zippers arranged alternately, which increases its sealing and security.
[0014] As described above, in the front panel of a sealed zipper bag, the area containing the front zipper strap and snap is transparent, while other areas are opaque. This ensures that the shape of the zipper is visible from the outside of the sealed zipper bag, while also providing some visual obstruction and protection for the contents. The front zipper straps of the two zippers are arranged in the shape of an animal (such as a fish or dolphin), with the snap positioned at the animal's eyes. This attracts children, causing them to skip the first step of opening the bag (i.e., pulling out the piston), thus reducing the risk of opening the bag.
[0015] As described above, in a sealed zipper bag, the left and right ends of the front zipper straps and the snaps are all slidably connected to the front panel. This means that the left ends of the front zipper straps of the two zippers are simultaneously fixedly connected to a slider a located between the front and back panels, and slider a is slidably connected to a slide rail a vertically arranged and fixed on the rear side of the front panel; the snaps are fixedly connected to a slider b located on the front side of the front panel, and slider b is slidably connected to a slide rail b vertically arranged and fixed on the front side of the front panel; the right ends of the front zipper straps of the two zippers are simultaneously fixedly connected to a slider c located between the front and back panels, and slider c is slidably connected to a slide rail c vertically arranged and fixed on the rear side of the front panel.
[0016] In the sealed zipper bag described above, one piston is located between the left ends of the front zipper straps of the two zippers, and another piston is located between the right ends of the front zipper straps of the two zippers.
[0017] The sealed zipper bag described above also includes two pull cords. One end of each pull cord is fixedly connected to the bag-shaped structure, and the other end is fixedly connected to two pistons respectively. This ensures that the pistons will not be lost when pulled out, but does not affect the pistons' ability to obstruct the slide rail. At the same time, if it is inconvenient to pull the pistons directly by hand, the pistons can be pulled out by pulling the pull cords. Since the pull cords are connected to the pistons, the force will be transmitted, so even if the hand directly applies force to the pull cords, the force will still be transmitted to the pistons.
[0018] As described above, a sealed zipper bag has suction nozzle-like structures on both the left and right sides of the bag-shaped structure. The two pistons are inserted into the bag-shaped structure from the left and right sides respectively and are sealed to it. This means that the two pistons are inserted into the two suction nozzle-like structures respectively and are sealed to them.
[0019] Beneficial effects:
[0020] This invention features a double-barrier design with zippers and pistons. Only by pulling out the pistons on both sides can the front and rear zipper straps be separated, making it difficult for children to open and ensuring higher safety. Attached Figure Description

[0027] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0028] A type of resealable zipper bag, such as Figures 1-3 As shown, it includes a front panel 1, a back panel 2, two zippers, a snap 5, two connectors, piston I 6, piston II 7, pull cord I 19, and pull cord II 20;
[0029] like Figure 2 As shown, the front piece 1 and the back piece 2 are connected to form a bag-like structure;
[0030] like Figure 2 , Figure 4 , Figure 5 As shown, two zippers are arranged horizontally between the front piece 1 and the back piece 2, with vertical spacing, and snap 5 is located on the front side of the front piece 1.
[0031] Both zippers include a front zipper strap 3 and a back zipper strap 4. The back zipper straps 4 of both zippers are fixedly connected to the back piece 2. The left and right ends of the front zipper straps 3 of both zippers and the snaps 5 are slidably connected to the front piece 1. The sliding is synchronous and the sliding direction is up and down. The specific implementation method is as follows:
[0032] like Figure 3 As shown, the left ends of the front chain straps 3 of the two zippers are simultaneously fixedly connected to a slider a located between the front piece 1 and the back piece 2. The slider a is slidably connected to a slide rail a 16 arranged vertically and fixed on the rear side of the front piece.
[0033] The snap 5 is fixedly connected to a slider b located on the front side of the front piece 1, and the slider b is slidably connected to a slide rail b 17 arranged vertically and fixed on the front side of the front piece 1.
[0034] The middle part of the front chain straps 3 of the two zippers is fixedly connected to the snaps 5 by two connectors respectively. The front piece 1 is provided with strip-shaped holes for the two connectors to pass through when the two connectors slide with the front chain straps 3 and the snaps 5.
[0035] The right ends of the front chain straps 3 of the two zippers are simultaneously fixedly connected to a slider c located between the front piece 1 and the back piece 2. The slider c is slidably connected to a slide rail c 18 that is vertically arranged and fixed on the rear side of the front piece 1.
[0036] In the front piece 1, the area containing the front chain strap 3 and snap 5 is transparent, while the other areas are not transparent;
[0037] The front zipper straps 3 are arranged in the shape of an animal, and the snaps 5 are located at the position of the animal's eyes;
[0038] The bag-shaped structure has suction nozzle-like structures on both the left and right sides. Piston I 6 and piston II 7 are respectively inserted into the two suction nozzle-like structures and sealed to them. Piston I 6 is located between the left ends of the front chain tapes 3 of the two zippers, and piston II 7 is located between the right ends of the front chain tapes 3 of the two zippers.
[0039] like Figure 3 As shown, one end of pull rope I 19 and pull rope II 20 are simultaneously fixedly connected to the bag-shaped structure, the other end of pull rope I is fixedly connected to piston I 6, and the other end of pull rope II 20 is fixedly connected to piston II 7.
[0040] To open the sealed zipper bag, first pull out the two pistons, then press down on the snap 5. Since the front chain straps 3 of the two zippers are fixedly connected to the snap 5, and the snap 5 and the front chain straps 3 of the two zippers are slidably connected to the front piece 1 through the slide rail a, the slider b and the slider c respectively, when you press down on the snap 5, the front chain straps 3 of the two zippers will slide down with the snap 5, causing the front chain straps 3 and the rear chain straps 4 of the two zippers to separate, thereby opening the sealed zipper bag.
