Description

Technical Field

[0001] The utility model relates to the technical field of paper bags, in particular to a waterproof and sealed packaging paper bag. Background Art

[0002] Due to the recyclability and easy degradability of paper bags, which are beneficial to environmental protection, paper bags are gradually replacing plastic bags. In daily life, people often use paper bags to hold items. The handbag is mostly of an integral structure. After the bottom is folded, it is fixed with glue to hold items. A layer of PP material can be coated on the paper to make the paper bag have a waterproof effect, and a sealing structure can be set at the mouth of the paper bag to achieve a sealing effect.

[0003] At present, a Chinese utility model patent application with a publication date of July 18, 2023 and a publication number of CN219361871U proposes a paper bag, which includes a front bag surface and a rear bag surface. The characteristics are as follows: the front bag surface and the rear bag surface are formed by folding a piece of paper, and the corresponding folding part forms the bottom of the integral bag body. The two side edges of the front bag surface and the rear bag surface are both set as M-shaped insertion edges. A sealing flap is provided at the upper end of the front bag surface, and an adhesive part is provided on the sealing flap, and the adhesive part is adhesively matched with the rear bag surface; the utility model effectively prevents the bottom of the bag body from being damaged, increases the capacity of the bag body, and is convenient for quickly sealing the bag body.

[0004] However, the sealing effect of the above paper bag is not good. If a paper bag with a sealing structure is used, after using the sealed paper bag to store or take out food, the sealing structure on the paper bag is easy to get stained with impurities and is not easy to remove. After the sealing structure is stained with impurities, when sealing again, the impurities are easy to be stuck in the sealing structure, causing the air inside and outside the sealed paper bag to circulate, affecting the sealing effect of the paper bag. Moreover, when the impurities are stuck in the sealing structure, it will cause damage to the sealing structure and affect its service life. Summary of the Invention

[0005] The utility model provides a waterproof and sealed packaging paper bag, which can solve the technical problem that impurities adhered to the sealing structure in the paper bag in the related technology are difficult to remove and affect its sealing effect.

[0031] A paper bag refers to any bag whose material contains a part of paper and can be collectively referred to as a paper bag; due to the recyclability and easy degradability of paper bags, which are beneficial to environmental protection, paper bags are gradually replacing plastic bags. In daily life, people often use paper bags to hold items. The shopping bag is mostly an integral structure. After the bottom is folded, it is fixed with glue to hold items. A layer of PP material can be laminated on the paper to make the paper bag waterproof, and a sealing structure can be set at the mouth of the paper bag to achieve a sealing effect.

[0032] However, if a paper bag with a sealing structure is used, after using the sealed paper bag to store or take out food, the sealing structure on the paper bag is likely to be contaminated with impurities and is not easy to remove. After the sealing structure is contaminated with impurities, when sealing again, the impurities are likely to be stuck inside the sealing structure, allowing air to circulate inside and outside the sealed paper bag, affecting the sealing effect of the paper bag. Moreover, when the impurities are stuck inside the sealing structure, it will cause damage to the sealing structure and affect its service life.

[0033] Based on this, to address the problem in the related art that the impurities stuck to the sealing structure in the paper bag are difficult to remove and affect the sealing effect of the paper bag, the embodiments of this application provide the following solutions.

[0034] An embodiment of the present application provides a waterproof and sealed packaging paper bag, which includes a paper bag body 10, a sealing component 20 and a scraping component 30. The paper bag body 10 includes a storage part 11 and a sealing part 12. The sealing part 12 includes a first sealing edge 121 and a second sealing edge 122. The sealing component 20 includes a sealing strip 21, a first connecting plate 22, a first sealing plate 23, a second sealing plate 24 and a second connecting plate 25. The sealing strip 21 is arranged on the first sealing edge 121 through the first connecting plate 22. The first sealing plate 23 and the second sealing plate 24 are both arranged on the second sealing edge 122 through the second connecting plate 25. A sealing cavity 26 for forming a seal with the sealing strip 21 is formed among the first sealing plate 23, the second sealing plate 24 and the second connecting plate 25. The scraping component 30 includes a scraping block 31. A groove 311 is formed on one side of the scraping block 31, and a convex block 312 is connected to the other side. The inner wall of the groove 311 is slidably attached to the side wall of the sealing strip 21, and the side wall of the convex block 312 is slidably attached to the inner wall of the sealing cavity 26.

[0035] As can be seen from the above, for the waterproof and sealed packaging paper bag provided by the embodiment of the present application, when impurities adhere to the sealing component 20, move the scraping block 31 so that the sealing strip 21 is placed in the groove 311, and the convex block 312 is placed in the sealing cavity 26. Then slide the scraping block 31 along the length directions of the sealing strip 21 and the sealing cavity 26. The inner wall of the groove 311 is slidably attached to the side wall of the sealing strip 21, and the side wall of the convex block 312 is slidably attached to the inner wall of the sealing cavity 26, so that the impurities on the sealing strip 21 and the sealing cavity 26 are scraped off or scraped to the edge of the sealing component 20. When there are impurities at the edge of the sealing component 20, the user only needs to clean the sealing strip 21 and the sealing cavity 26 at the edge of the sealing component 20 to achieve the effect of removing impurities, which improves the cleaning efficiency. Therefore, due to the arrangement of the scraping block 31, the groove 311 and the convex block 312, when impurities adhere to the sealing component 20, the user can move the scraping block 31, scrape the impurities on the sealing strip 21 through the groove 311, and scrape the impurities in the sealing cavity 26 through the convex block 312, so that the impurities are difficult to be stuck in the sealing structure, enhancing the sealing effect of the paper bag and increasing the service life of the sealing component 20.

[0036] In some embodiments, please also refer to Figures 3 to 6 , the scraping component 30 further includes a third connecting plate 32, a rotating shaft 33, a second slideway 34 and a connecting seat 35. One end of the third connecting plate 32 is connected to the scraping block 31, and the other end is connected to the rotating shaft 33. The rotating shaft 33 is slidably arranged in the second slideway 34, and the second slideway 34 is fixedly installed on the connecting seat 35.

[0037] With such a setting, when there are impurities on the sealing assembly 20, place the sealing strip 21 in the groove 311 and place the bump 312 in the sealing cavity 26. Move the connecting seat 35 along the length direction of the sealing part 12. The second slideway 34 moves, and drives the third connecting plate 32 and the scraping block 31 to move through the rotating shaft 33, so as to scrape the impurities on the sealing strip 21 and in the sealing cavity 26. After scraping, when the scraping block 31 needs to be stored, flip the scraping block 31 so that the scraping block 31 is placed above the connecting seat 35, and move the scraping block 31 in the direction close to the connecting seat 35. The rotating shaft 33 slides in the second slideway 34 until the whole scraping block 31 can be statically placed on the top of the connecting seat 35 through the third connecting plate 32. Release the scraping block 31 to complete the storage, and the operation is simple and convenient. Therefore, the setting of the third connecting plate 32, the rotating shaft 33, the second slideway 34 and the connecting seat 35 facilitates the user to move and store the scraping block 31.

[0038] Optionally, in some embodiments, please refer to Figures 2 to 4 , a chute 123 is provided on both the first sealing edge 121 and the second sealing edge 122, and the connecting seat 35 is slidably arranged on the chute 123.

[0039] With such a setting, when there are impurities on the sealing assembly 20, place the sealing strip 21 in the groove 311 and place the bump 312 in the sealing cavity 26. The user can move the connecting seat 35 along the length direction of the sealing part 12 without putting the hand into the inner side of the sealing part 12, and the operation is more convenient. Therefore, the setting of the chute 123 facilitates the user to move the connecting seat 35.

[0040] Optionally, please refer to Figures 2 to 3 , both ends of the connecting seat 35 are fixedly connected with sliders 37 through connecting blocks 36, and first slideways 124 are arranged on both sides of the first sealing edge 121 and the second sealing edge 122 away from each other, and the sliders 37 are slidably arranged on the first slideways 124.

[0041] With such a setting, when the connecting seat 35 is moved, the slider 37 slides on the first slideway 124 and is difficult to shake, so that the connecting seat 35 is also difficult to shake during the movement, which facilitates the user to control the scraping block 31 to scrape the impurities on the sealing assembly 20 through the connecting seat 35. Therefore, the setting of the slider 37 and the first slideway 124 makes the connecting seat 35 difficult to shake during the movement, and further facilitates the user to control the movement of the scraping block 31.

[0042] Optionally, please refer to Figures 5 to 6 , one side of the scraping block 31 close to the connecting seat 35 is in contact with the side wall of the connecting seat 35.

[0043] With such a setting, when the connecting seat 35 moves towards the side close to the scraping block 31, the scraping block 31 abuts against the side wall of the connecting seat 35. When the connecting seat 35 drives the scraping block 31 to move for scraping, it is difficult for the scraping block 31 to shake, which improves the cleaning efficiency of the scraping block 31 for cleaning the sealing assembly 20, and the operation is simple and convenient.

[0044] Optionally, in some embodiments, please refer to Figure 4 , the first sealing plate 23 and the second sealing plate 24 are both arc-shaped. A first guiding surface 231 is formed between the end surface of the first sealing plate 23 away from the connecting plate and the end surface close to the second sealing plate 24, and a second guiding surface 241 is formed between the end surface of the second sealing plate 24 away from the connecting plate and the end surface close to the first sealing plate 23.

[0045] With such a setting, the sealing cavity 26 formed by the first sealing plate 23, the second sealing plate 24 and the second connecting plate 25 is arc-shaped, which is convenient for fixing the sealing strip 21 in the sealing cavity 26. When the user seals the paper bag, the sealing strip 21 is aligned with the opening of the sealing cavity 26, and the sealing strip 21 is gently pressed. The side wall of the sealing strip 21 abuts against the first guiding surface 231 and the second guiding surface 241, and the ends of the first sealing plate 23 and the second sealing plate 24 away from the second connecting plate 25 are forced to move in a mutually separated direction until the sealing strip 21 is snapped into the sealing cavity 26. The first sealing plate 23 and the second sealing plate 24 clamp and fix the pen under the action of elastic force to form a seal. Therefore, the setting of the first guiding surface 231 and the second guiding surface 241 facilitates the user to snap the sealing strip 21 into the sealing cavity 26 to form a seal, and the operation is simple and convenient.

[0046] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
