Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a handle-type packaging bag. Background Technology

[0002] In daily life and business activities, tote bags are widely used in shopping, food transportation, and item storage. The handles of existing tote bags are often simple in structure and do not fully consider the principles of ergonomics. Carrying them for a long time can cause hand discomfort or even damage. In addition, some tote bags have poor heat preservation effects and are not suitable for storing products that require insulation at low temperatures. Therefore, a new type of tote bag is proposed.

[0003] Chinese Utility Model Patent Publication No. CN 215754021 U discloses a handle-type packaging bag. This bag has an internal divider to separate wine bottles, preventing damage during handling and transportation. The divider is divided into horizontal and vertical sections, allowing for convenient horizontal or vertical placement of the bottles. When a wine bottle is placed horizontally, the wine inside soaks the cork at the bottle neck, preventing air leakage due to dryness and ensuring wine quality. However, the handle is narrow, which can be uncomfortable to hold, resulting in a poor user experience. The bag also has poor sealing, allowing dust to easily penetrate, and insufficient insulation; if refrigerated wines are handled, the wine may warm up, failing to achieve the desired refrigeration effect. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a hand-held packaging bag that can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a hand-held packaging bag, including a packaging bag body, with sealing strips pasted and connected to the front and rear ends of the inner wall of the packaging bag body, a first handle fixedly connected to the front end of the packaging bag body, and a second handle fixedly connected to the rear end of the packaging bag body;

[0006] The packaging bag body includes an outer layer, a heat insulation layer, a buffer layer, and an inner layer. The heat insulation layer is adhered to the inner wall of the outer layer, the buffer layer is adhered to the inner wall of the heat insulation layer, and the inner layer is adhered to the inner wall of the buffer layer.

[0007] Both the outer and inner layers are made of recycled paper. The insulation layer is a composite material made of polyethylene film laminated with aluminum foil. The buffer layer is made of either kraft paper with a honeycomb structure or thermoplastic polyurethane material filled with polyurethane foam to achieve a buffering effect.

[0008] Through the above technical solutions, the outer layer uses recycled paper, which has good tensile strength and toughness, and can withstand certain external forces such as stretching, bending, and friction. It is relatively durable, aesthetically pleasing, and highly decorative. The inner layer also uses recycled paper, which has a certain degree of stiffness. When the items inside the bag are irregularly shaped or have a certain weight, the inner layer can provide some support, and together with the cushioning layer, it can better fix the position of the items. The insulation layer is made of polyethylene film laminated with aluminum foil. The aluminum foil has excellent reflective properties and can reflect a large amount of heat radiation, reducing heat loss. The polyethylene film can prevent external moisture from entering the packaging bag, enhancing the moisture-proof capability of the packaging bag. When the cushioning layer is made of kraft paper with a honeycomb structure, it further absorbs external forces. The energy-absorbing material provides excellent cushioning. When the cushioning layer is made of thermoplastic polyurethane material filled with polyurethane foam, the thermoplastic polyurethane material air bladder will undergo elastic deformation when subjected to external impact, absorbing and dispersing the impact force. The air bladder can return to its original shape after the pressure is removed. At the same time, the filled polyurethane foam also has good elasticity and cushioning performance. When external force is applied, the foam can be compressed to further absorb energy. The combination of the two forms a cushioning layer that can provide efficient cushioning protection for the items inside the bag. The air inside the air bladder and the polyurethane foam enable the cushioning layer to play a certain role in heat preservation while cushioning. Together with the insulation layer, it enhances the heat preservation effect, allowing the packaging bag to hold items that need to be refrigerated and kept warm.

[0009] Preferably, the first magnetic stripe and the second magnetic stripe are magnetically connected, and the sealing strip is made of hot melt adhesive.

[0010] Through the above technical solution, magnetic strip one and magnetic strip two are magnetically connected. The magnetic connection method of the magnetic strips makes the sealing operation of the packaging bag simple and convenient, and can complete the sealing more quickly, improving the efficiency of use. The sealing strip made of hot melt adhesive has good flexibility and sealing performance, which can closely fit the opening of the packaging bag, effectively blocking external factors such as dust, moisture, and air from entering the bag and maintaining a relatively stable environment inside the bag.

[0011] Preferably, an upper handle can be fixedly connected to the upper end of the first handle, and a lower handle can be fixedly connected to the upper end of the second handle.

[0012] The upper handle includes an upper handle base, the upper handle base has grooves at its front and rear ends, a locking piece is provided inside the grooves, a locking block is provided at the lower end of the locking piece, a locking pin is fixedly connected to the lower end of the upper handle base, and upper fixing seats are fixedly connected to both sides of the upper handle base, with alignment grooves provided at the lower end of the upper fixing seats.

[0013] The lower handle includes a lower handle base, with locking grooves at the front and rear ends of the lower handle base, slots on the surface of the locking grooves, a round hole at the upper end of the lower handle base, and lower fixing seats fixedly connected to both sides of the lower handle base, with a plate at the upper end of the lower fixing seat.

[0014] Preferably, the upper handle seat and the lower handle seat are adapted to each other, the diameter of the locking pin is equal to the diameter of the slot, and the insert plate is adapted to the alignment slot.

[0015] Preferably, the lower end of the lower handle has an arc-shaped finger groove, the thickness of the locking piece is the same as the depth of the locking groove, the locking piece and the locking groove are rotatably connected, the locking block is adapted to the slot, and the lower end of the locking block has an inclined surface.

[0016] Through the above technical solution, the upper and lower handle seats cooperate to ensure the structural integrity and stability of the handle. This allows the force to be evenly distributed across the entire handle structure when the user lifts the packaging bag, improving the handle's load-bearing capacity. When the packaging bag needs to be lifted, the upper and lower handle seats are aligned, the locking pin is inserted into the slot, and the insert plate is inserted into the alignment slot to complete the alignment. This enhances the accuracy and firmness of the connection between the upper and lower handle seats. The lower handle seat has an arc-shaped finger groove that conforms to ergonomic principles. When the user carries the packaging bag, their fingers can be naturally and comfortably placed in the finger groove, reducing hand pressure. A locking piece is provided. After aligning the upper and lower handle seats from both sides, rotating the locking piece allows the locking block to be inserted into the slot, thereby locking the upper handle seat to the slot. The beveled design makes it easier to insert the locking block into the slot when assembling the handle.

[0017] Compared with the prior art, the present invention provides a handle-type packaging bag, which has the following beneficial effects:

[0018] 1. This tote bag features an outer layer made of recycled paper, which boasts excellent tensile strength and toughness, capable of withstanding certain stretching, bending, and friction forces. It is durable, aesthetically pleasing, and highly decorative. The inner layer, also made of recycled paper, possesses inherent stiffness, providing support when the contents are irregularly shaped or heavy. Combined with a cushioning layer, it effectively secures the items. Recycled paper is low-cost to manufacture and offers some water resistance, ensuring strength while maintaining waterproof functionality, making it more energy-efficient and environmentally friendly.

[0019] 2. This portable packaging bag features an insulation layer made of polyethylene film laminated with aluminum foil. The aluminum foil has excellent reflective properties, reflecting a large amount of heat radiation and reducing heat loss. The polyethylene film prevents external moisture from entering the bag, enhancing its moisture resistance. The cushioning layer is made of thermoplastic polyurethane material filled with polyurethane foam. When subjected to external impact, the thermoplastic polyurethane material air bladders undergo elastic deformation, absorbing and dispersing the impact force. The air bladders can return to their original shape after the pressure is released. At the same time, the filled polyurethane foam also has good elasticity and cushioning performance. When external force is applied, the foam can be compressed to further absorb energy. The combined effect of these two materials forms a cushioning layer that provides efficient cushioning protection for the items inside the bag. The air and polyurethane foam inside the air bladders allow the cushioning layer to also provide insulation while cushioning. Together with the insulation layer, this greatly enhances the insulation effect of the packaging bag, making it suitable for storing refrigerated and frozen items.

[0020] 3. The magnetic connection design of magnetic strips one and two in this hand-held packaging bag makes the sealing operation extremely simple and quick. Users only need to gently close the packaging bag opening, and the magnetic strips will automatically attract. The sealing strip made of hot melt adhesive fits tightly against the bag opening, enhancing the sealing effect and effectively blocking dust, moisture and air. At the same time, in conjunction with the multi-layer structure of the packaging bag body, it improves the heat preservation effect for items that need to be refrigerated and kept warm.

[0021] 4. This handle-style packaging bag features an upper handle and a lower handle. When the bag needs to be carried, align the upper and lower handles, insert the locking pin into the slot, and insert the plate into the alignment slot to complete the alignment. Rotate the locking piece to insert the locking block into the slot, thereby locking the upper handle and the slot. The lower handle has an arc-shaped finger groove that conforms to ergonomic principles. When the user carries the packaging bag, their fingers can be placed naturally and comfortably in the finger groove, reducing hand pressure. The stable handle structure can withstand greater weight and pulling force, providing users with a reliable way to carry the bag. Attached Figure Description
