Description

Technical Field

[0001] This utility model mainly relates to the technical field of plastic bags, specifically a transparent plastic bag that is easy to separate. Background Technology

[0002] Plastic bags are commonly used as packaging materials for various items such as food, clothing, and stationery. They can protect items from dust, moisture, and damage, while also being convenient to carry and store. In supermarkets, shopping malls, and other shopping venues, plastic bags are often used as shopping bags to facilitate consumers carrying their purchased goods. They are widely used. However, when existing plastic bags are stored tightly or rolled up for a long time, due to their thinness and static electricity, they are difficult to unfold when taken out. Therefore, there is a need for a new type of easily separable transparent plastic bag.

[0003] According to application number 201821603681.0, the foldable plastic bag and plastic bag roll include an integrally formed bag body and a handle, wherein the bottom of the bag body and the top of the handle are wavy. Compared with the prior art, this utility model sets the connection between the plastic bags to be wavy, which is more effortless and provides a better and more comfortable experience when tearing off the plastic bag compared with the current method of connecting with buckles.

[0004] The aforementioned document makes it easy to tear off the plastic bag by adjusting the tear-off design at the joint, but it lacks a quick structural design for unfolding the plastic bag. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an easily separable transparent plastic bag to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A detachable transparent plastic bag includes a main bag body with an opening at the top and two handles at both ends of the opening connected to the main bag body. Two folding grooves extending to the handles are pressed together at both ends of the main bag body. A thick bottom is heat-bonded to the bottom of the main bag body. Two pull strips are symmetrically arranged on one side of the main bag body near the opening. A first pull strap is heat-bonded to one side of the main bag body in the middle of the two pull strips. A second pull strap is heat-bonded to the other side of the main bag body.

[0008] Preferably, the two ends of the bag opening extend to the two bag handles facing each other, and the inner circle of the bag opening is thermoformed with annular pleats.

[0009] Preferably, the connection between the bag handle and the bag opening is rounded, and the top of the bag handle is thermoformed with a first easy-tear strip.

[0010] Preferably, the inner wall of the folding groove has a first side pleat thermoformed on both sides, and the outer wall of the folding groove has a second side pleat thermoformed on the side near the second pull strap.

[0011] Preferably, the bottom of the thick bag is provided with two second easy-tear strips at both ends, which connect the two first easy-tear strips.

[0012] Preferably, one end of the pull strip is heat-bonded to one side of the main bag body, and the other end of the pull strip is folded and scattered outside one side of the main bag body, with a plastic ring heat-bonded to the scattered end of the pull strip.

[0013] Preferably, the top of the first pull strap is close to the bag opening, and the top of the second pull strap is slightly lower than the bag opening, forming a height misalignment between the second pull strap and the first pull strap.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention utilizes a pull tab design to easily open the plastic bag after folding it in half. The extended end of the pull tab and the heat-bonded plastic ring facilitate gripping and handling, preventing the pull tab from being too tightly pressed and difficult to remove. The staggered design of the first and second pull tabs prevents uneven winding caused by excessively thick pull tabs when the plastic bag is being rolled. After unfolding the folded plastic bag, users can easily open the bag opening using the first and second pull tabs, improving efficiency.

[0016] By designing a first and second easy-tear strap and setting an easy-tear line at the connection point, only a short distance needs to be torn when taking out a single plastic bag, reducing the chance of tearing the plastic strap. This design makes the separation process of plastic bags more convenient and improves the user experience. The optimized structural design, with rounded corners at the connection between the bag handle and the bag opening, effectively prevents tearing caused by right-angle connections. At the same time, the thermoplastic edge pleats on the inner ring of the bag opening and the inner wall of the folding groove prevent the bag opening from sticking together due to electrostatic adsorption and the folding groove from being difficult to unfold properly, making the plastic bags more convenient to use.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example

[0024] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 4, an easily separable transparent plastic bag includes a main bag body 10. The top of the main bag body 10 has a bag opening 11. Two bag handles 12 are connected to the main bag body 10 at both ends of the bag opening 11. Two folding grooves 13 extending to the bag handles 12 are pressed together at both ends of the main bag body 10. A thick bag bottom 14 is heat-bonded to the bottom of the main bag body 10. Two pull strips 15 are symmetrically arranged on one side of the main bag body 10 near the bag opening 11. A first pull strap 16 heat-bonded to one side of the main bag body 10 is located in the middle of the two pull strips 15. On the other side, a second pull strap 17 is heat-bonded; the two ends of the bag opening 11 extend to the two bag handles 12 facing end, and the inner circle of the bag opening 11 is heat-plasticized with annular side pleats 111; the connection between the bag handle 12 and the bag opening 11 is rounded, and the top of the bag handle 12 is heat-plasticized with a first easy-tear strip 121; the inner walls of the folding groove 13 are heat-plasticized with first side pleats 131 on both sides, and the outer wall of the folding groove 13 is heat-plasticized with a second side pleat 132 on the side near the second pull strap 17; the bottom of the thick bag bottom 14 is cut with two second easy-tear strips 141 connecting the two first easy-tear strips 121 at both ends.

[0025] As described above, each plastic bag is folded in half and rolled up end to end before use. The two first easy-tear straps 121 and two second easy-tear straps 141 are connected before use, with an easy-tear line at the connection point. The bags are connected via relatively short first and second easy-tear straps 121 and 141. When removing a single plastic bag, only a shorter distance needs to be torn. Compared to a plastic strap structure that requires tearing the entire connection point, this reduces the chance of tearing the plastic strap. Additionally, the two bag handles 12, when unfolded, facilitate easy lifting of the plastic straps. The bag handles 12 and the bag... The opening 11 has a rounded corner to prevent tearing due to uneven force when opening the bag due to a right-angle connection. The inner ring of the opening 11 has a thermoplastic annular pleat 111 to prevent the opening from sticking together due to static electricity, making it easy to open the bag. Similarly, the first pleat 131 on both sides of the inner wall of the folding groove 13 is thermoplastic, which makes it easy for the folding groove 13 to unfold normally. The second pleat 132 on the outer wall of the folding groove 13 near the second pull strap 17 will stick together when the plastic strip is folded, which also makes it easy to unfold when taking out the plastic strip.

[0026] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 3, one end of the pull strip 15 is heat-bonded to one side of the main bag body 10, and the other end of the pull strip 15 is folded and scattered outside one side of the main bag body 10. A plastic ring 151 is heat-bonded to the scattered end of the pull strip 15. The top of the first pull strap 16 is close to the bag opening 11, and the top of the second pull strap 17 is slightly lower than the bag opening 11. The second pull strap 17 and the first pull strap 16 are misaligned.

[0027] As described above, when unfolding the folded plastic bag, the two pull strips 15 can be used to pull the plastic bag apart. The loose pull strips 15 can be easily pulled, and the heat-bonded plastic ring 151 can make it easy for people to grab the loose ends of the pull strips 15, preventing the pull strips 15 from being pressed tightly and difficult to remove after winding. The second pull strip 17 and the first pull strip 16 are staggered in height, which can prevent the second pull strip 17 and the first pull strip 16 from being too thick when the plastic bag is wound, resulting in uneven winding. After unfolding the folded plastic bag, the bag opening 11 can be easily opened by the first pull strip 16 and the second pull strip 17.

[0028] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
