Description

Technical Field

[0001] This utility model relates to the field of easy-open sealing structures, and in particular to a zipper-type easy-open sealing structure for packaging bags. Background Technology

[0002] Fertilizer bags are bags used to package fertilizers. They have functions such as moisture protection, leak protection, and dust protection to ensure the quality and safety of fertilizers during transportation and storage. Common sizes include 5 kg, 10 kg, 25 kg, 40 kg, and 50 kg bags. 5 kg and 10 kg bags are suitable for home gardening or small-scale growers.

[0003] Existing small fertilizer bags are generally made of plastic, which has good weather resistance, moisture resistance, and water resistance, effectively protecting fertilizer from the influence of the external environment. The opening of existing plastic fertilizer bags is usually a notch on one side, allowing users to open the fertilizer bag through the notch. However, when opening the fertilizer bag through the notch, it is easy to tear the notch crookedly, preventing the fertilizer bag from being fully opened. After the notch is torn crookedly, it is also easy to tear the bag body, causing the fertilizer inside to leak out.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-4One embodiment of this utility model is a zipper-type easy-open sealing structure for a packaging bag, including a bag body 1, a pull plate 2 fixedly provided on the upper end face of the bag body 1, a tear strip 3 heat-sealed on the adjacent side of the outer surface of the bag body 1 and the pull plate 2, a reinforcing strip 4 fixedly provided in the middle of the inner side of the tear strip 3, two tear ears 6 fixedly provided on one side of the tear strip 3, a connecting surround 8 fixedly provided on the upper end of the inner surface of the bag body 1, and two press-type zippers 9 fixedly provided on the inner surface of the connecting surround 8.

[0018] Specifically, bag 1 is a commonly used small fertilizer bag. Since it is a mature and publicly available technology, its specific structure and working principle will not be elaborated upon here. Bag 1 is connected to a tear strip 3 and a lifting plate 2. The lifting plate 2 has a certain rigidity, facilitating user movement of the entire bag. The tear strip 3 is heat-sealed and connected to the outer surface of the bag 1 and the lifting plate 2. The tear strip 3 is made of flexible polyethylene plastic material, possessing certain tear resistance and ductility. A reinforcing strip 4 is fixed in the middle of the inner side of the bag 3 to enhance the mechanical properties of the overall structure and ensure that it is not easy to break during the tearing process. Two tear ears 6 are symmetrically arranged on one side of the tear strip 3. The tear ears 6 make it convenient for users to tear the tear strip 3. A connecting surround 8 is also fixedly arranged at the upper part of the inner surface of the bag body 1. Two press-type zippers 9 are fixedly arranged on the inner surface of the connecting surround 8. The press-type zippers 9 achieve engagement and disengagement by pressing, so that the bag body 1 can be resealed after the first opening, effectively maintaining the freshness and moisture-proof performance of the contents.

[0019] Reference Figure 1-4 The front end of the lifting plate 2 has handles 5 embedded and fixed on both sides. The handles 5 are made of rigid polystyrene plastic. The tear strip 3 is made of polyethylene plastic. The tear ear 6 has BOPP film embedded and fixed inside. The two tear ears 6 are each slidably provided with connecting posts 10. The front and rear ends of the connecting posts 10 are fixed with fixing blocks 7. The connecting surround 8 is made of polyethylene plastic. The press-type zipper 9 includes a convex rail and a concave rail.

[0020] Specifically, handles 5 are embedded and fixed on both sides of the front end face of the lifting plate 2. The handles 5 are made of rigid polystyrene plastic, which has excellent compressive strength and durability, and provides a good grip during use, making it convenient for users to move the entire structure through the handles 5. A layer of BOPP film is embedded inside the tear ear 6. BOPP has high tensile strength, impact strength, rigidity and toughness, which improves the strength and creep resistance of this part. The fixing block 7 and the connecting post 10 can form a restraining structure. The restraining structure passes through the two tear ears 6 during use, restraining the tear ears 6 and preventing the tear ears 6 from being torn during movement. When it is necessary to tear the tear strip 3, the staff needs to use scissors to cut the connecting post 10 and then use the tear ear 6 to tear the tear strip 3. The connecting surround 8 is made of polyethylene plastic, which has good flexibility and sealing properties, allowing the connecting surround 8 to be firmly set inside the bag body 1. The press-type zipper 9 includes a convex rail and a concave rail, which achieves engagement and disengagement by pressing.

[0021] Special note: This device is mainly used on small fertilizer bags, such as 5-jin bags and 10-jin bags. After fertilizing indoor plants, the bags can be sealed with a press-type zipper 9, allowing the fertilizer inside the bags to be stored for a longer period of time.

[0022] Working principle: The bag body 1 is connected to the lifting plate 2 via the tear strip 3. The tear strip 3 is connected to the outer surface of the bag body 1 and the lifting plate 2 through a heat sealing process. Two tear ears 6 are symmetrically arranged on one side of the tear strip 3. The tear ears 6 make it convenient for the user to tear the tear strip 3 during use. A reinforcing strip 4 is fixed in the middle of the inner side of the tear strip 3 to enhance the mechanical properties of the overall structure and ensure that it is not easy to break during the tearing process. When taking fertilizer, use scissors to cut the connecting post 10, and use the tearing ear 6 to tear the tear strip 3. After the tear strip 3 is torn, the lifting plate 2 can be removed from the top of the bag body 1, allowing the staff to open the press-type zipper 9 inside the bag.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
