Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a plastic-free paper packaging bag for the outer packaging of diapers. Background Technique

[0002] Diaper packaging bags are used to seal diapers and play a good protective role during the transportation and sale of diapers. Currently, several diapers are usually packaged in the same diaper packaging bag. Once the packaging bag is unsealed, the remaining diapers will be exposed to the air, and moisture, dust, bacteria, etc. in the air can cause the diapers to be contaminated. To solve this defect, manufacturers usually set up a reusable seal press-type sealing strip or other structures in the packaging bag, or each diaper is provided with a separate packaging. However, it is difficult to avoid the contamination of other diapers when taking the diapers in the packaging bag with the press-type sealing strip, and setting a separate packaging for each diaper will increase the use of packaging materials, thereby increasing the production cost of diapers.

[0003] The publication number CN220282192U discloses a moisture-proof packaging bag, which includes a bag body. A tear strip for opening the bag body is provided on the bag body. A storage cavity and a moisture-proof cavity are arranged inside the bag body. A sealing component for sealing the bag body and a moisture-proof component for moisture-proof inside the bag body are arranged in the bag body. The moisture-proof component includes a lifting plate, an elastic cord, a one-way air valve and a positioning plate. The positioning plate is placed at the opening of the bag body, the lifting plate is placed at one end of the bag body far from the opening, the positioning plate and the lifting plate are connected by an elastic cord, and the one-way air valve is arranged on the bag body to communicate the storage cavity with the outside of the bag body. The above packaging bag keeps the inside of the bag body sealed through the sealing component, and discharges and absorbs moisture from the gas inside the bag body through the moisture-proof component, which can effectively avoid the situation of diapers getting damp. However, after taking the diapers multiple times, pollutants such as bacteria and dust carried by the human hand will continuously accumulate in the packaging bag, and the remaining diapers in the packaging bag may be contaminated after the pollutants accumulate for a long time. Therefore, there is still room for improvement in this packaging bag. Content of the Utility Model

[0004] In view of the technical defects existing in the background technique, the utility model provides a plastic-free paper packaging bag for the outer packaging of diapers, which solves the above technical problems and meets the actual needs. The specific technical solutions are as follows:

[0005] A plastic-free paper packaging bag for the outer packaging of disposable diapers, comprising a packaging bag body, a first-generation plastic-free paper, and a second-generation plastic-free paper. The packaging bag body is successively provided with a top layer, a plurality of partition layers, and a bottom layer from top to bottom. Side layers are provided between the top layer and the adjacent partition layer, between adjacent partition layers, and between the bottom layer and the adjacent partition layer. The inside of the side layer is hollow to form a plurality of packaging cavities in the packaging bag body. The bottom edge of the top layer, the edge of the partition layer, and the top edge of the bottom layer are respectively adhesively fixed to the adjacent side layers;

[0006] The top layer, the bottom layer, and the side layer are all made of the first-generation plastic-free paper. The first-generation plastic-free paper is successively composed of a heat-sealing layer, a base paper layer, and a barrier layer along the thickness direction. The side of the first-generation plastic-free paper close to the heat-sealing layer is located inside the packaging cavity; the partition layer is made of the second-generation plastic-free paper. The second-generation plastic-free paper is successively composed of a heat-sealing layer, a base paper layer, and a heat-sealing layer along the thickness direction.

[0007] As a further technical solution of the present utility model, a tearing strip is provided on one side of the side layer.

[0008] As a further technical solution of the present utility model, the side layer is formed by folding and adhesively connecting the head and tail of the first-generation plastic-free paper. The position where the head and tail of the first-generation plastic-free paper are adhesively connected forms a side sealing edge on one side of the packaging bag body.

[0009] As a further technical solution of the present utility model, an arc-shaped carrying handle is provided on one side of the packaging bag body. Both ends of the carrying handle are fixedly connected to the side sealing edge.

[0010] As a further technical solution of the present utility model, the carrying handle is made of a third-generation plastic-free paper.

Detailed Embodiments

[0021] The following describes the embodiments of the present utility model in conjunction with the accompanying drawings and related embodiments. The embodiments of the present utility model are not limited to the following embodiments, and the relevant necessary components involved in the present utility model should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0022] Such as Figures 1-4As shown in the figure, a plastic-free paper packaging bag for the outer packaging of diapers includes a packaging bag body 1, a first-generation plastic-free paper 2a, and a second-generation plastic-free paper 2b. The packaging bag body 1 is successively provided with a top layer 11, a plurality of partition layers 12, and a bottom layer 13 from top to bottom. Side layers 14 are provided between the top layer 11 and the adjacent partition layer 12, between adjacent partition layers 12, and between the bottom layer 13 and the adjacent partition layer 12. The inside of the side layer 14 is hollow, so that a plurality of packaging cavities 15 are formed inside the packaging bag body 1. The bottom edge of the top layer 11, the edges of the partition layers 12, and the top edge of the bottom layer 13 are adhesively fixed to the adjacent side layers 14 respectively; the top layer 11, the bottom layer 13, and the side layers 14 are all made of the first-generation plastic-free paper 2a. The first-generation plastic-free paper 2a is successively composed of a heat-sealing layer 21, a base paper layer 22, and a barrier layer 23 along the thickness direction. The side of the first-generation plastic-free paper 2a close to the heat-sealing layer 21 is located inside the packaging cavity 15; the partition layer 12 is made of the second-generation plastic-free paper 2b. The second-generation plastic-free paper 2b is successively composed of a heat-sealing layer 21, a base paper layer 22, and a heat-sealing layer 21 along the thickness direction.

[0023] The utility model is mainly used for packaging diapers. The top layer 11, a plurality of side layers 14, and the bottom layer 13 form a cuboid structure with a hollow interior as the basic structure of the packaging bag body 1. The internal space of the packaging bag body 1 is divided into a plurality of independent packaging cavities 15 by a plurality of partition layers 12. The diapers are packaged in the plurality of packaging cavities 15. Each packaging cavity 15 can package at least one diaper. The number of diapers packaged in each packaging cavity 15 is preferably close to the number of diapers that a baby needs to change in a day. When the diaper is needed, any packaging cavity 15 can be torn open. After all the diapers in the packaging cavity 15 are used up, another packaging cavity 15 is torn open. After such an operation, the diapers in the same packaging cavity 15 will usually be used up within two days, which can shorten the time from the diaper being unpacked to being officially used, and avoid the pollutants from accumulating inside the packaging due to the long time of the diaper packaging being opened, thus contaminating the remaining diapers, and making the diapers in a relatively clean state when being used.

[0024] It should be noted that the inner packaging of a common diaper packaging bag contains 30 - 100 diapers. Usually, an infant needs to change 3 - 10 diapers per day. As the infant grows older, the number of diapers to be changed per day decreases and the size of the diapers increases. Then, each packaging cavity 15 can be designed to package 3 - 10 diapers. The larger the size of the diapers, the fewer the number of diapers packaged in the same packaging cavity 15, so that the number of diapers an infant needs to change per day matches the capacity of the packaging cavity 15, and thus the diapers packaged in each packaging cavity 15 can be used up within two days. In addition, each packaging cavity 15 can contain only one diaper, making the packaging cavity 15 an independent package for the diaper. Each time a diaper is needed, just tear open one packaging cavity 15, which can store the diapers independently and prevent the diapers from being contaminated by pollution sources before use. In the diaper packaging method of the present utility model, the number of diapers in the same package is reduced. Currently, common similar packaging methods are usually achieved through small packaging bags with low capacity. Although reducing the capacity of the small packaging bag can shorten the time from opening the package to the formal use of the diapers inside, packaging the same number of diapers will require more packaging bag raw materials, thus increasing the packaging cost. In the packaging bag body 1 of the present utility model, each packaging cavity 15 can be regarded as a small packaging bag for packaging diapers, and an adjacent packaging cavity 15 shares a separation layer 12, which can reduce the usage amount of raw materials and the packaging cost.

[0025] After adopting the above structure, in the first-generation plastic paper 2a and the second-generation plastic paper 2b of the present utility model, the base paper layer 22 can be preferably selected from common wood pulp paper and kraft paper. The top surface layer 11, the bottom surface layer 13, and the side surface layer 14 are all the outer surface structures of the packaging bag body 1. Therefore, the base paper layer 22 in the first-generation plastic paper 2a is preferably made of paper with a grammage greater than 60 gsm to ensure the protection strength of the packaging bag body 1. And the separation layer 12, as a structure for separating the diapers in adjacent packaging cavities 15, does not need to have high strength and is usually made of paper with a grammage less than 60 gsm. In addition, the heat-sealing layer 21 is formed by curing after coating one of starch-based heat-sealing materials and cellulose-based heat-sealing materials on the surface of the base paper layer 22. The heat-sealing layer 21 makes the top surface layer 11, the separation layer 12, and the bottom surface layer 13 be adhesively fixed to the adjacent side surface layer 14 through heat-sealing to form the packaging bag body 1. And the barrier layer 23 is formed by curing after coating one of starch-based barrier materials and cellulose-based barrier materials on the surface of the base paper layer 22. The barrier layer 23 can prevent air, liquid, etc. from penetrating the first-generation plastic paper 2a, thereby improving the sealing performance, waterproof performance, etc. of the packaging bag body 1. Moreover, the base paper layer 22, the heat-sealing layer 21, and the barrier layer 23 are all made of degradable materials, so that the packaging bag body 1 can be completely naturally degraded in the natural environment, thus replacing the currently common packaging materials made of difficult-to-degrade plastic materials and improving environmental protection.

[0026] It should be noted that the process of the packaging bag body 1 packaging the diapers is as follows: The bottom layer 13 and several partition layers 12 are respectively heat-sealed and fixed to several side layers 14 to form several packaging cavities 15. Then, one packaging cavity 15 is placed on the operating table, and a set amount of diapers are neatly loaded into the packaging cavity 15. Then, another packaging cavity 15 is stacked on top of the packaging cavity 15 and heat-sealed and fixed to each other. Then, a set amount of diapers are loaded into the top packaging cavity 15, and so on. Finally, the top layer 11 is covered on the top of the uppermost packaging cavity 15 and heat-sealed and fixed, so as to obtain the packaging bag body with the diapers packaged inside.

[0027] In summary, in the present utility model, the top layer 11, the partition layer 12, and the bottom layer 13 are respectively adhesively fixed to the adjacent side layers 14 to form the packaging bag body 1 with several mutually independent packaging cavities 15. A partition layer 12 is shared between adjacent packaging cavities 15, which can reduce the usage amount of raw materials. Packaging the diapers through the packaging cavities 15 can shorten the time experienced by the diapers from being unpacked to being used, and avoid the enrichment of pollutants inside the packaging due to the long time of the packaging of the diapers being unpacked, thus polluting the remaining diapers, and enabling the diapers to be in a relatively clean state when being used.

[0028] As Figure 1 、 2 shown, as one of the preferred embodiments of the present utility model, a tear strip 16 is provided on one side of the side layer 14; the tear strip 16 is formed by processing the first-generation plastic paper 2a on the side close to the heat-sealing layer 21 through a die-cutting machine. During the processing, the cutting piece intermittently cuts the surface of the first-generation plastic paper 2a to form a dotted tear line. The cutting depth does not penetrate the barrier layer 23, so that the thickness of the position of the first-generation plastic paper 2a provided with the tear line is reduced and an easily tearable tear strip 16 is formed. By tearing the tear strip 16, an opening can be formed on the side of the packaging cavity 15. This opening facilitates the user to take out the diapers in the packaging cavity 15 and enables the packaging bag body 1 to maintain a high integrity.

[0029] As Figure 1 、 2 shown, as one of the preferred embodiments of the present utility model, the side layer 14 is formed by folding the first-generation plastic paper 2a and adhesively connecting the head and tail. The position where the head and tail of the first-generation plastic paper 2a are adhesively connected forms a side seal edge 17 on one side of the packaging bag body 1; the first-generation plastic paper 2a forms a rectangular ring-shaped side layer 14 after folding and heat-sealing and adhesively connecting the head and tail. After the flat first-generation plastic paper 2a forms the side seal edge 17 through heat-sealing and adhesively connecting, a three-dimensional side layer 14 is obtained, so that the side layer 14 can cooperate with the top layer 11, the partition layer 12, and the bottom layer 13 to form a packaging cavity 15 for packaging diapers.

[0030] As Figure 1 、2 As shown in the figure, as one of the preferred embodiments of the present utility model, an arc-shaped carrying handle 3 is provided on one side of the packaging bag body 1, and both ends of the carrying handle 3 are fixedly connected to the side sealing edge 17; when the top layer 11, the separating layer 12, and the bottom layer 13 are respectively adhered and fixed to the side layer 14 to form the packaging bag body 1, both ends of the carrying handle 3 are respectively fixed to the side sealing edges 17 of two of the side layers 14, so that a carrying handle 3 is formed on one side of the packaging bag body 1. The carrying handle 3 can enable consumers to more conveniently pick up the packaging bag body 1 containing diapers.

[0031] As Figure 5 shown, as one of the preferred embodiments of the present utility model, the carrying handle 3 is made of the third-generation plastic paper 2c. The third-generation plastic paper 2c is sequentially composed of a barrier layer 23, a base paper layer 22, a toughening layer 24, and a barrier layer 23 along the thickness direction; in the third-generation plastic paper 2c, the toughening layer 24 can use materials with high toughness and degradability such as polylactic acid fibers as raw materials. The polylactic acid fibers are twisted and woven to form a net structure as the toughening layer 24, which can increase the toughness of the third-generation plastic paper 2c. The barrier layer 23 can prevent external liquids from penetrating into the third-generation plastic paper 2c, so that the carrying handle 3 has good toughness, and the carrying handle 3 can be prevented from breaking when picking up the packaging bag body 1 containing diapers.

[0032] As Figure 1 、 2 shown, as one of the preferred embodiments of the present utility model, the bottom edge of the top layer 11, the edge of the separating layer 12, and the top edge of the bottom layer 13 are respectively adhered to the adjacent side layer 14 to form a plurality of separating sealing edges 18; the separating sealing edges 18 are heat-sealing and adhering structures for respectively fixing the top layer 11, the separating layer 12, and the bottom layer 13 to the adjacent side layer 14, which improves the structural stability of the packaging bag body 1.

[0033] As one of the preferred embodiments of the present utility model, in the first-generation plastic paper 2a and the second-generation plastic paper 2b, the heat-sealing layer 21 is arranged around the edge of the base paper layer 22; in the packaging bag body 1, the top layer 11, the separating layer 12, and the bottom layer 13 are respectively heat-sealed and adhered to the edges of the adjacent side layer 14 at the edges. Therefore, the heat-sealing layer 21 only needs to be arranged around the edge of the base paper layer 22, which can reduce the usage amount of the heat-sealing material and reduce the manufacturing cost of the packaging bag body 1.

[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
