Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging bags, in particular to a packaging bag with a safety buckle. Background Art
[0002] OOP bags, or oriented polypropylene bags, are plastic packaging bags made of polypropylene (PP) material. Polypropylene is a widely used plastic raw material with good physical and chemical properties, such as chemical resistance, heat resistance, impact resistance and easy processing. OOP bags have been widely used in many fields due to their unique properties and advantages.
[0003] The current OOP packaging bags are usually sealed at the opening with self-adhesive labels or sealing strips. The use of self-adhesive labels is limited. When using the sealing strips, the strips on both sides of the opening need to be aligned and then squeezed to seal. However, the sealing strips are often not compacted. The prior art provides a sliding lock on the sealing strip. The sliding lock can be pulled to compact the sealing strip as a whole, thereby closing the packaging bag. However, the sliding lock sliding back and forth multiple times can easily cause the opening of the packaging bag to crack and cause the sliding lock to slide out. In addition, the sliding lock can also be accidentally touched, causing the opening of the packaging bag to open. On the other hand, some packaged products require the inside of the packaging bag to be breathable, while other products require good sealing. The current packaging bags cannot take into account the packaging of different types of products. Therefore, a packaging bag with a safety buckle is proposed to solve the above problems.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0030] Reference Figure 1-Figure 3The utility model provides an embodiment of a packaging bag with a safety buckle, comprising a packaging bag 1 for containing packaging products, a sealing component is arranged on the inner side of the top opening of the packaging bag 1, and the sealing component is used to seal the opening of the packaging bag 1, and the sealing component comprises a sealing strip 2, and the sealing strip 2 is arranged in two groups, and the outer sides of the two groups of sealing strips 2 are respectively arranged on the inner side of the top opening of the packaging bag 1, and the two groups of sealing strips 2 are aligned and squeezed against each other, and they will be engaged with each other to ensure sealing, and the sealing strip 2 is slidably connected with a slide lock 3 inside, and the slide lock 3 slides to the right, and the pressure block inside the slide lock 3 will squeeze the sealing strips 2 on both sides inward to close the opening of the packaging bag 1, and the slide lock 3 slides to the left, and the internal block of the slide lock 3 will open the sealed sealing strip 2 to open the opening of the packaging bag 1, and the slide lock 3 is slidably connected to the top of the packaging bag 1, and the front and rear sides of the sealing component are both open. A card slot 4 is provided, and the card slot 4 is opened on the front and rear sides of the slide lock 3. A group of protective blocks 5 are fixedly connected to the left and right sides of the top of the packaging bag 1. The protective blocks 5 will block the force when the sliding slide lock 3 reaches the edge to prevent the slide lock 3 from causing damage to the two sides of the opening of the packaging bag 1. A limiting groove 6 is provided on the inner side of the protective block 5, and the outer periphery of the slide lock 3 contacts the inner side of the limiting groove 6. An elastic buckle 7 is fixedly connected to the inner side of the limiting groove 6. The elastic buckle 7 is only arranged on the inner side of the right side protective block 5, and the left side of the elastic buckle 7 is set as an inclined surface. When the elastic buckle 7 is subjected to force from the left side, the inclined surface on the left side of the elastic buckle 7 will convert part of the future force into an upward force, thereby causing the elastic buckle 7 to deform upward, and the bottom of the elastic buckle 7 is clamped in the inside of the card slot 4, so that the slide lock 3 cannot move to the left. A hook groove 8 is provided on the outer side of the elastic buckle 7, which is convenient for lifting the elastic buckle 7 to unlock the slide lock 3.
[0031] Reference Figure 2-Figure 4 The packaging bag 1 is provided with air holes 9, and there are four groups of air holes 9, which are symmetrically arranged on the left and right sides of the packaging bag 1, and the air holes 9 of the front and rear groups are opposite to each other. A group of fixed sleeves 10 are fixedly connected to the air holes 9 of the two groups on each side, and the outer periphery of the fixed sleeves 10 is fixedly connected to the inside of the protective block 5. The outer periphery of the fixed sleeves 10 is provided with air grooves 11, and the air grooves 11 are arranged in several groups, which are evenly distributed in the air grooves 11 in an annular shape. The front and rear ends of the fixed sleeves 10 are fixedly connected with sealing rings 12, and the inner side of the sealing rings 12 is fixedly connected to the outer side of the protective block 5, so as to improve the fixed sleeves 10 and the protective block 5. In order to improve the sealing performance, an extrusion ring 13 is in contact with the inner side of the fixed sleeve 10 through an interference fit, and a push buckle 14 is fixedly connected to the outer side of the extrusion ring 13. The push buckle 14 blocks the front and rear openings of the fixed sleeve 10 to prevent air from circulating. The diameter of the push buckle 14 is larger than the diameter of the sealing ring 12, so that there is a gap between the push buckle 14 and the sealing ring 12, which is convenient for pulling out the push buckle 14. The extrusion ring 13 can be removed by squeezing the push buckle 14 inwardly or pulling it outwardly. An annular groove 15 is provided on the inner side of the push buckle 14, and the outer peripheries of the two ends of the fixed sleeve 10 are slidably connected to the inside of the annular groove 15 to improve the sealing performance of the push buckle 14.
[0032] Working principle: when you want to close the opening of the packaging bag 1, slide the slide lock 3 to the right, and the slide lock 3 makes the sealing strip 2 close. When the slide lock 3 slides to the right side of the packaging bag 1, the slide lock 3 enters the limiting groove 6, pushing the left inclined surface of the elastic buckle 7, so that the left end of the elastic buckle 7 is tilted upward. When the elastic buckle 7 is inserted into the card slot 4, the slide lock 3 cannot open the sealing strip 2 to the left. Use the hook groove 8 to lift the elastic buckle 7 upwards, and then slide the slide lock 3 to the left. At the same time, the protective block 5 improves the durability of the two sides of the opening of the packaging bag 1, and the elastic buckle 7 slows down the speed of the slide lock 3 sliding to the right, thereby reducing the cracking of the two sides of the opening of the packaging bag 1. On the other hand, when the product inside the packaging bag 1 needs to be ventilated, the push buckle 14 is pulled outward, and the openings on both sides of the fixed sleeve 10 are opened, and air can enter the packaging bag 1 through the breathable groove 11 on the inner wall of the fixed sleeve 10. The push buckle 14 is pressed inward to make the extrusion ring 13 fit into the fixed sleeve 10, and the openings on both sides of the fixed sleeve 10 are closed, so that air cannot circulate.
[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
