Description

Technical Field

[0001] This application relates to the field of packaging bag technology, and in particular to a biodegradable packaging bag. Background Technology

[0002] "Degradable" refers to packaging bags that, under specific environmental conditions (such as natural environments, composting environments, industrial composting conditions, etc.), can gradually decompose into environmentally harmless substances (such as carbon dioxide, water, biomass, etc.) through microbial decomposition, photolysis, oxidation, or hydrolysis, ultimately achieving complete degradation of the material and avoiding long-term residue causing environmental pollution. "Packaging bags" refer to flexible containers used for product packaging, transportation, storage, or consumption. Degradable packaging bags can be applied to the following common types: shopping bags: degradable plastic bags used in retail scenarios such as supermarkets and shopping malls, replacing traditional PE plastic bags.

[0003] Garbage bags: Biodegradable garbage bags used in households or public places to reduce environmental pollution from landfill or incineration.

[0004] Food packaging bags: Biodegradable materials used for packaging food, such as starch-based composite films and PLA-coated paper bags, must meet food safety standards.

[0005] A search revealed Chinese Patent Publication No. CN221719298U, which discloses a biodegradable plastic packaging bag. The bag includes a main body with a storage groove in the center of its upper surface. Limiting blocks and snap-fit ​​blocks are fixedly connected to both sides of the front and rear outer walls of the main body. A carrying rope is fixedly connected to the center of the upper surface of each limiting block. In this invention, when the user needs to adjust the height of the carrying rope, they apply force to the limiting springs by pinching the sides of the semi-circular sponge block. This compression of the limiting springs simultaneously compresses the sliding sponge pad. The compression of the sponge pad causes the slider above its circular pad to slide within a groove, thus limiting the position of the limiting springs and preventing positional shift during compression. Pulling the carrying rope moves the plastic tube and the sliding sponge pad into the snap-fit ​​hole, thereby adjusting the length of the carrying rope.

[0006] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies in this patent:

[0007] While this patent allows users to easily switch between carrying the bag by hand or over their shoulder, the direct contact between the user's hands and shoulders with the carrying strap may cause marks on the user's arms due to the strap's action, making it inconvenient for users to carry the bag by hand or over their shoulder for extended periods.

[0008] Therefore, in response to the above problems, the applicant provides a biodegradable packaging bag. Utility Model Content

[0009] To address the problems mentioned in the background section, this application provides a biodegradable packaging bag.

[0010] This application provides a biodegradable packaging bag, which adopts the following technical solution:

[0011] A biodegradable packaging bag includes a bag body and a carrying strap. The carrying strap is provided with a carrying mechanism that has both hand-carrying and shoulder-carrying functions. The carrying mechanism includes two shoulder-carrying components and two rubber handles. Rubber magnetic strips are adhered to the outer circumference of the two shoulder-carrying components, which are close to each other, and the two rubber magnetic strips attract each other.

[0012] Both of the rubber grips are embedded with magnetic blocks, and the two magnetic blocks attract each other.

[0013] The packaging bag has grooves on both sides that are close to each other, and magnetic strips are embedded in each groove.

[0014] Optionally, it also includes a packaging bag body, wherein limit blocks and snap-fit ​​blocks are fixedly connected to both sides of the packaging bag body, and a lifting rope is provided on both the limit blocks and the snap-fit ​​blocks.

[0015] Optionally, a shoulder and back assembly is fitted onto both the limiting block and the snap-fit ​​block. The shoulder and back assembly consists of a sliding sleeve and a shoulder strap. The shoulder strap is a nylon shoulder strap, and the sliding sleeve is a polyester fiber sleeve.

[0016] Optionally, the shoulder strap has a support ring hole, a support ring is inserted into the support ring hole, and a positioning rod passes through the top of the support ring.

[0017] Optionally, the positioning rod is circumferentially wrapped with a rubber grip, and the rubber grip has multiple grip grooves.

[0018] Optionally, the load-bearing ring is an aluminum ring.

[0019] Optionally, the packaging bag body is a PLA bag body.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. This utility model, through the design of the carrying mechanism, allows users to switch between hand-carrying and shoulder-carrying as needed. The shoulder strap and rubber grip prevent wear and tear caused by direct contact between the user's hands or shoulders and the carrying rope, thus facilitating the user's long-term handling or shoulder-carrying of the packaging bag.

[0022] 2. This utility model, through the setting of the back-lifting mechanism, places two shoulder-carrying components on the shoulders. The mutual attraction of the rubber magnetic strips keeps the two shoulder-carrying components in close contact, thereby avoiding the trouble of a single shoulder-carrying component slipping off the shoulder from time to time, which would require the user to hold one shoulder-carrying component by hand.

[0023] 3. This utility model allows the magnetic strips on the packaging bag to automatically adhere together when they come into contact with each other, thus preventing insects, hair, or small particles from falling onto clothes through the opening of the packaging bag and causing them to get dirty. In addition, the space inside the packaging bag is relatively fixed after it is closed, reducing the compression and wrinkling of clothes. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a biodegradable packaging bag.

[0033] like Figure 1-6As shown, a biodegradable packaging bag includes a bag body 1 and a carrying strap 5. The carrying strap 5 is provided with a carrying mechanism that has hand-carrying and shoulder-carrying functions. The carrying mechanism includes two shoulder-carrying components 6 and two rubber handles 11. The outer walls of the two shoulder-carrying components 6 are close to each other and are each bonded with a rubber magnetic strip 7. The two rubber magnetic strips 7 attract each other and have a certain degree of flexibility so that they can bend with the shoulder-carrying components 6 without deformation.

[0034] Both of the rubber grips 11 are embedded with magnetic blocks 10, and the two magnetic blocks 10 attract each other.

[0035] The packaging bag body 1 has grooves 100 on both sides that are close to each other, and magnetic strips 2 are embedded in each groove 100.

[0036] Please see Figure 1 It also includes a packaging bag body 1, on which limit blocks 3 and snap-fit ​​blocks 4 are fixedly connected to both sides. A lifting rope 5 is provided on both the limit blocks 3 and the snap-fit ​​blocks 4. The structure of the limit blocks 3 and the snap-fit ​​blocks 4 is based on the structure of announcement number CN221719298U. The length of the lifting rope 5 can be adjusted through the structure set inside the snap-fit ​​blocks 4. The internal structure of the snap-fit ​​blocks 4 will not be described in detail here.

[0037] Please see Figure 1 Each of the limiting block 3 and the snap-fit ​​block 4 is fitted with a corresponding shoulder and back assembly 6. The shoulder and back assembly 6 consists of a sliding sleeve 60 and a shoulder strap 61. The shoulder strap 61 is a nylon shoulder strap, and the sliding sleeve 60 is a polyester fiber sleeve. The sliding sleeve 60 is provided with a lifting rope hole, and the sliding sleeve 60 can slide on the lifting rope 5. The shoulder strap 61 is convenient for the operator to carry on their shoulders and back, and avoids chafing the user's shoulders.

[0038] Please see Figure 2 The shoulder strap 61 has a load-bearing ring hole 610, and a load-bearing ring 8 is inserted into the load-bearing ring hole 610. The top end of the load-bearing ring 8 passes through the positioning rod 9. The load-bearing ring 8 serves to connect the shoulder and back assembly 6 and the positioning rod 9.

[0039] Please see Figure 4 The positioning rod 9 is surrounded by a rubber grip 11, which has multiple grip grooves 110. The grip grooves 110 make it easy for the operator to grip the handle, and the rubber grip 11 makes it easy for the user's hand to contact the handle to reduce wear.

[0040] Please see Figure 3 The load-bearing ring 8 is an aluminum ring. The load-bearing ring 8 made of aluminum material has a certain tensile strength, thereby serving to connect the magnetic block 10 and the shoulder and back assembly 6.

[0041] Please see Figure 1The packaging bag body 1 is a PLA bag body. PLA is made of polylactic acid, which is obtained by fermentation of corn starch. Its molecular chain contains ester bonds. Under composting conditions, it is hydrolyzed into lactic acid and CO2 by esterases secreted by microorganisms, thus achieving the purpose of biodegradation.

[0042] The implementation principle of a biodegradable packaging bag in this application embodiment is as follows:

[0043] After clothes are placed in the packaging bag 1, the two sides of the packaging bag 1 are sealed together from the bottom to the top to make contact between the two sides. This can expel the air inside the packaging bag 1. At the same time, when the user touches the two sides of the magnetic strip 2 on the packaging bag 1, they will automatically attract each other. This prevents insects, hair or small particles from falling onto the clothes through the opening of the packaging bag 1 and causing them to get dirty. After closing, the space inside the packaging bag 1 is relatively fixed, reducing the compression and wrinkling of the clothes.

[0044] The carrying mechanism has two modes: hand carrying and shoulder carrying. The usage process is as follows:

[0045] After clothes are placed in the packaging bag 1, the two sides of the packaging bag 1 are sealed together from the bottom to the top to expel air from the inside of the packaging bag 1. At the same time, when the user touches the two sides of the magnetic strip 2 on the packaging bag 1, they will automatically attract each other, thus preventing insects, hair or small particles from falling onto the clothes through the opening of the packaging bag 1 and causing them to get dirty. After closing, the space inside the packaging bag 1 is relatively fixed, reducing the compression and wrinkling of the clothes.

[0046] When shoulder carrying is required, after adjusting the carrying strap 5 to a suitable length, the operator connects the two shoulder carrying components 6 and the two rubber handles 11 together. The rubber magnetic strip 7 attracts the two shoulder carrying components 6, and the magnetic block 10 attracts the two rubber handles 11 together. The operator simply places the two shoulder carrying components 6 on their shoulders. The mutual attraction of the rubber magnetic strip 7 keeps the two shoulder carrying components 6 in close contact, thus avoiding the trouble of a single shoulder carrying component 6 slipping off the shoulder from time to time, which would require the user to hold one shoulder carrying component 6 in place. At the same time, the load-bearing ring 8 positions the rubber handles 11, and the two rubber handles 11 attract each other through the magnetic block 10, thus preventing them from drooping on the user's shoulders and causing inconvenience.

[0047] If the packaging bag body 1 needs to be carried by hand, the operator can shorten the length of the carrying rope 5 and carry it with the rubber handle 11. With the design of carrying by hand and carrying on the shoulder, the operator can flexibly choose the way to carry the magnetic strip 2 according to their own needs, thereby avoiding the wear and tear caused by the user's hands and shoulders directly contacting the carrying rope 5.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
