Description

Technical Field

[0001] The utility model discloses an automatically closed paper bag, belonging to the field of paper bags. Background Art

[0002] Paper bags are bags made of a material that contains some paper.

[0003] Nowadays, most paper bags have an open opening design and no lid design, which makes the items in the bag easy to get lost or contaminated by dust, making the safety and hygiene of the items in the bag not guaranteed.

[0004] A paper bag with an automatic closing lid is now proposed to solve the problem that the paper bag has no lid and cannot ensure the safety and hygiene of the items in the bag. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a paper bag with an automatic closing lid.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: an automatically closing paper bag, comprising a bag body, a lifting portion and a storage cavity, wherein bendable lids that can completely cover the bag opening are slidably provided on both sides of the storage cavity, a support plate is fixedly connected to the bottom of the lid, the support plate is fixedly connected to a pull rod that can drive the lid to slide, and the pull rod slides out of the storage cavity to form a lifting portion.

[0007] The utility model is further configured as follows: the storage cavity is provided with a convex block 1 at the opening thereof which can change the bending direction of the cover, and the convex block 1 is in an arc shape.

[0008] The utility model is further configured as follows: the storage cavity is provided with two protrusions on both sides where no cover is provided, the two protrusions can change the bending direction of the cover and can support both sides of the cover, and the cover is in contact with the two protrusions.

[0009] The utility model is further configured as follows: an inner wall of the storage cavity is provided with a butt plate, the cover does not butt against the butt plate, the support plate can butt against the butt plate, the butt plate is formed with a hole, and the pull rod slides out of the hole.

[0010] The utility model is further configured as follows: the second protrusion is configured lower than the first protrusion along the depth direction of the paper bag.

[0011] The utility model is further configured as follows: the cover is in an arc shape.

[0012] In summary, the utility model has the following beneficial effects: when the product is in use, the lifting part can be pulled to lift the bag body, and the pulling force of the lifting part will drive the support plate and the lid to slide toward the opening. Since the protrusion 1 makes the lid bend horizontally, when the support plate abuts against the baffle, the lid also completely covers the opening of the paper bag, which largely solves the problem that the paper bag is not designed with a lid and cannot ensure the safety and hygiene of the items in the bag.

[0017] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 and Figure 2 As shown, an automatic closing paper bag of the present embodiment comprises a bag body 1, a lifting portion 2 and a storage cavity 3, a bendable lid 4 which can completely cover the bag opening is slidably provided on both sides of the storage cavity 3, a support plate 5 is fixedly connected to the bottom of the lid 4, the support plate 5 is fixedly connected to a pull rod 6 which can drive the lid 4 to slide, the pull rod 6 slides out of the storage cavity 3 to form the lifting portion 2, and a protrusion 7 which can change the bending direction of the lid 4 is provided at the opening of the storage cavity 3, and the protrusion 7 is in an arc shape.

[0019] When the product is in use, the articles can be placed in the storage cavity 3 first, and then the lifting portion 2 is pulled upwards. Since the lid 4 slides in the storage cavity 3, the bottom of the lid 4 is fixedly connected to the support plate 5, and the pull rod 6 is fixedly connected to the support plate 5. The pull rod 6 extends out of the paper bag to form the lifting portion 2. Therefore, pulling the lifting portion 2 will cause the pulling force to be transmitted from the pull rod 6 to the support plate 5, causing the lid 4 fixedly connected to the support plate 5 to also be subjected to an upward pulling force, so the lid 4 slides upward. When the lid 4 abuts against the protrusion 7, since the protrusion 7 is in an arc shape, the lid 4 will slide along the arc-shaped surface of the protrusion 7 after the abutment, and the lid 4 will change from a vertical state to a horizontal state, forming a cover surface that can completely cover the bag opening, which largely solves the problem that the paper bag has no cover and cannot ensure the safety and hygiene of the articles in the bag.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the storage cavity 3 is formed with protrusions 8 on both sides where the lid 4 is not provided. The protrusions 8 can change the bending direction of the lid 4 and can support both sides of the lid 4. The lid 4 abuts against the protrusions 8. An abutment plate 9 is provided on the inner wall of the storage cavity 3. The lid 4 does not abut against the abutment plate 9. The support plate 5 can abut against the abutment plate 9. The abutment plate 9 is formed with a hole 10. The pull rod 6 slides out of the hole 10. The protrusions 8 are arranged lower than the protrusions 1 7 along the depth direction of the paper bag, and the lid 4 is in an arc shape.

[0021] When the product is in use, the articles can be placed in the storage cavity 3 first, and then the lifting part 2 can be pulled to make the lid 4 slide toward the bag opening. When the lid 4 is changed in bending direction by the protrusion 1 7 and completely covers the bag opening, the support plate 5 fixedly connected to the lid 4 abuts against the abutment plate 9. At this time, the pulling force of the lifting part 2 will be transmitted to the bag body 1 along the abutment plate 9, so that the paper bag can be completely lifted. Because the protrusion 2 8 is set lower than the protrusion 1 7, when the lid 4 is in a horizontal state, due to the influence of its own gravity, the lid 4 bends toward the inside of the paper bag. The protrusion 2 8 can support both sides of the lid 4, so that the lid 4 will not bend to extend into the storage cavity 3 and touch the articles in the bag, thereby ensuring that the integrity of the articles in the bag will not be affected when the product is used, thereby greatly improving the practicality of the product.

[0022] After using the product, the paper bag can be placed on the table, and the lifting part 2 can be pushed downward, so that the thrust is transmitted to the support plate 5 along the pull rod 6, driving the lid 4 to slide downward. Since the lid 4 is in a horizontal state at this time, when the lid 4 abuts against the arc-shaped protrusion 28, the lid 4 slides along the arc-shaped protrusion 28 and gradually changes from a horizontal state to a vertical state. When the support plate 5 abuts against the bottom of the bag, the lid 4 is fully opened, and the lid 4 abuts against the protrusion 28, so that the lid 4 will not bend in the storage cavity 3, and the lid 4 is in an arc shape, which greatly ensures that the items placed in the storage cavity 3 will not be affected by the lid 4. Because the abutment plate 9 is formed with a hole 10, the pull rod 6 slides out in the hole 10, so when the lifting part 2 is pulled or pushed to transmit the force to the pull rod 6, the support plate 5 fixedly connected to the pull rod 6 will not be misaligned, resulting in failure to put down or lift normally, which greatly increases the practicality of the product.
