Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to an insulated bag. Background Technology

[0002] An insulated bag is a type of outdoor bag used for outdoor picnics or daily life to hold various foods and maintain their temperature and freshness. It is designed to keep food warm or cold. The insulation layer uses extra-thick insulation cotton to provide excellent heat insulation.

[0003] However, existing insulated backpacks have a complex lid structure, consisting of multiple components: the lid body, the upper edge, and the lower edge. Decorative rings are also provided on the circumference of the upper and lower edge pieces, making it at least six parts. This results in two layers on the outer ring of the lid, increasing the seams and reducing its overall integrity, as shown in patent document CN218073854U. Furthermore, to ensure a good seal, the sealing ring is designed as a T-shape, and the upper surface of the upper edge is a large flat surface to increase the contact area. However, this greatly increases the material required to produce the sealing ring. Therefore, a corresponding T-shaped groove needs to be designed on the lower edge, resulting in high mold costs for the sealing ring and the lower edge piece. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an insulated bag.

[0005] This utility model is achieved by the following method: an insulated bag includes an insulated bag body with an opening at the top and a cover at the opening. The cover includes a cover body, a lower edge, and an upper edge. The upper edge is located at the opening. One side of the lower edge is hinged to one side of the upper edge. The lower surface of the lower edge has an upwardly protruding groove, and a sealing ring is provided in the groove. The upper surface of the upper edge has a protrusion opposite to the groove for pressing the sealing ring. The cover body covers the lower edge.

[0006] Preferably, a plurality of first magnetic elements are provided in the lower edge, and a second magnetic element is provided in the corresponding position in the upper edge, wherein the first magnetic elements and the second magnetic elements attract and cooperate with each other.

[0007] Preferably, the cover is connected to a strap with a male or female buckle, and the outer side of the insulated package away from the hinge of the upper and lower edges is provided with a corresponding female or male buckle.

[0008] Preferably, the upper surface of the upper edge piece is provided with a plurality of positioning blocks spaced around it, and the distance between the positioning blocks and the corresponding side of the upper edge piece is equal to the thickness of the side of the cover.

[0009] Preferably, the cover has a concave lower surface, and the distance between the sidewall of the concave area and the outer side of the cover is equal to the distance between the positioning block and the corresponding side of the upper edge piece.

[0010] Preferably, the sidewalls of the recessed area are provided with reinforcing ribs at intervals, and the reinforcing ribs avoid the positioning block.

[0011] Preferably, the distance between adjacent reinforcing ribs on both sides of the positioning block is equal to the width of the positioning block.

[0012] Preferably, the upper edge is annular; the upper surface of the lower edge is provided with a plurality of first mounting grooves at a position opposite to the upper edge and within the space surrounding the plurality of positioning blocks, wherein a first magnetic component is installed in the first mounting groove; and a plurality of second mounting grooves are provided inside the upper edge, wherein a second magnetic component is installed in the second mounting groove.

[0013] The beneficial effects of this utility model are as follows: This utility model provides an insulated bag, which, compared with the prior art, has at least the following technical effects: 1. The decorative rings on the outer periphery of the upper and lower edges are removed, reducing the number of parts and lowering production costs. At the same time, the seam between the cover and the decorative ring is eliminated, making the outer periphery of the bag cover more integrated and more aesthetically pleasing. Furthermore, the sealing ring is replaced with a common type of sealing ring, and the upper edge has a raised compression sealing ring that provides a good sealing effect. This eliminates the need for a separate mold for the sealing ring, and only a one-line groove is needed on the lower edge, making the mold structure simpler and also reducing production costs.

[0014] 2. The cover is secured to the top and bottom edges with magnetic attachment, pressing it firmly against the opening of the insulation package. Compared to the previous snap-on cover structure, this makes opening and closing easier for the user and provides a better user experience.

[0015] 3. The lid is connected with straps with male or female buckles, and the insulated bag is also equipped with corresponding female or male buckles, which can tighten the lid during transportation and prevent the lid from being opened during transportation.

[0016] 4. Multiple positioning blocks are arranged around the upper surface of the lower edge. The positioning blocks play a positioning role during the docking process between the cover and the lower edge, so that the outer peripheral surface of the cover is flush with the outer peripheral surface of the lower edge. This flushness of the outer peripheral surface of the cover reduces the abruptness of the seam and helps to enhance the overall appearance.

[0017] 5. Reinforcing ribs are provided on the concave sidewalls of the cover to increase the structural strength of the cover and prevent it from collapsing. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1 to 7 An insulated bag includes an insulated bag body 1 with an opening at the top. A cover is provided at the opening, and the cover includes a cover body 2, a lower edge 3, and an upper edge 4. The upper edge 4 is located at the opening. One side of the lower edge 3 is hinged to one side of the upper edge 4. The lower surface of the lower edge has an upwardly protruding groove 31, and a sealing ring 5 is provided in the groove 31. The upper surface of the upper edge 4 has a protrusion 41 opposite to the groove 31 for pressing the sealing ring 5. The cover body 2 covers the lower edge 3. The decorative rings around the upper edge 4 and lower edge 3 have been removed, reducing the number of parts and lowering production costs. At the same time, the seam between the cover body 2 and the decorative ring has been eliminated, resulting in a more integrated and aesthetically pleasing outer circumference of the cover. Furthermore, the sealing ring 5 has been replaced with a standard type of sealing ring 5. The upper edge has a protrusion 41 that compresses the sealing ring 5 to achieve a good sealing effect, eliminating the cost of making a separate mold for the sealing ring 5. The lower edge only needs to be provided with a straight groove, making the mold structure simpler and also reducing production costs.

[0028] Please see Figures 1 to 7 Preferably, the lower edge 3 is provided with a plurality of first magnetic elements 6, and the upper edge 4 is provided with second magnetic elements 7 at corresponding positions. The first magnetic elements 6 and the second magnetic elements 7 attract and cooperate with each other. The magnetic elements are used to hold the upper edge 4 and the lower edge 3 tightly together, that is, to press the cover 2 tightly against the opening of the insulation package 1. Compared with the previous cover-fastening structure, the user's opening and closing actions are simpler and the user experience is better.

[0029] Please see Figures 1 to 4 Preferably, the cover 2 is connected to a strap 8 with male or female buckles 9, and the outer side of the insulated bag 1 opposite to the hinge of the upper edge 4 and the lower edge 3 is provided with corresponding female or male buckles 9. The strap 8 with male or female buckles 9 connected to the cover 2, and the corresponding female or male buckles 9 on the insulated bag 1, can tighten the cover during transportation and prevent the cover from being opened during transportation.

[0030] Please see Figure 1 , Figures 3 to 5 Preferably, the upper surface of the upper edge piece is provided with a plurality of positioning blocks 32 spaced around it, and the distance between the positioning blocks 32 and the corresponding side of the upper edge piece is equal to the thickness of the side of the cover 2. The cover 2 has a concave lower surface, and the distance between the side wall of the concave part and the outer side of the cover 2 is equal to the distance between the positioning blocks 32 and the corresponding side of the upper edge piece. A plurality of positioning blocks 32 are provided around the upper surface of the lower edge 3. The positioning blocks 32 play a positioning role during the docking of the cover 2 and the lower edge 3, so that the outer peripheral surface of the cover 2 is flush with the outer peripheral surface of the lower edge 3 (avoiding slight indentation of the side of the cover 2 due to its own stress), so that the outer peripheral surface of the cover is flush, reducing the abruptness of the seam and helping to enhance the overall appearance.

[0031] Please see Figures 1 to 7 Preferably, the sidewalls of the recessed area are provided with reinforcing ribs 21 at intervals, and the reinforcing ribs 21 avoid the positioning block 32. The distance between adjacent reinforcing ribs 21 on both sides of the positioning block 32 is equal to the width of the positioning block 32. The reinforcing ribs 21 can increase the structural strength of the cover 2 and prevent the cover 2 from collapsing. At the same time, they can cooperate with the positioning block 32 to assist in the alignment and installation of the cover 2 and the lower edge 3.

[0032] Please see Figures 1 to 7Preferably, the upper edge 4 is annular; the upper surface of the lower edge 3 is provided with a plurality of first mounting grooves 33 at a position opposite to the upper edge 4 and within the space surrounding the plurality of positioning blocks 32, and a first magnetic element 6 is installed in the first mounting groove 33; a plurality of second mounting grooves 42 are provided inside the upper edge 4, and a second magnetic element 7 is installed in the second mounting groove 42. The annular shape of the upper edge 4 facilitates fixing the cover to the opening of the thermal insulation package 1, and forms an opening for taking out and putting in the thermal insulation package 1 in the upper edge 4 when the lower edge 3 and the cover 2 are opened around the hinge point.

[0033] Please see Figure 1 , Figures 3 to 7 A downwardly protruding positioning ring 43 is provided at the lower end of the inner circumferential surface of the upper edge 4. The outer circumferential dimension of the positioning ring 43 is equal to the inner circumferential dimension of the opening of the insulation package 1. This facilitates the accurate installation of the upper edge 4 at the opening of the insulation package 1.

[0034] Please see Figures 1 to 4 Preferably, the strap 8 is fixed to the upper surface of the cover 2 by rivets.

[0035] Please see Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 Preferably, the second mounting groove 31 of the lower edge 3 is opened upward from the lower surface of the upper edge 4, and the lower surface of the lower edge 3 abuts against the upper end surface of the opening of the thermal insulation package 1.

[0036] The working principle of this utility model is as follows:

[0037] During assembly, the second magnetic component 7 and the first magnetic component 6 are inserted into the upper edge 4 and the lower edge 3 respectively; then, the cover 2 and the lower edge 3 are aligned and pressed together (they can be glued together or ultrasonically welded together), and a common sealing ring 5 (which can be an O-shaped or rectangular sealing ring 5) is installed in the groove 31 of the lower edge 3. The upper edge 4 is installed at the opening of the insulation package 1 and fixed together by ultrasonic welding or other methods; then the lower edge 3 and the upper edge 4 are hinged together at the hinge joint.

[0038] When the cover 2 is closed, the entire cover 2 and the lower edge 3 are rotated around the hinge point, so that the entire lower edge 3 covers the upper edge 4. At this time, due to the presence of the first magnetic component 6 and the second magnetic component 7, the lower edge 3 will tightly cover the upper edge 4. The upper surface of the upper edge 4 is provided with a protrusion 41 opposite to the groove 31. The protrusion 41 presses the sealing ring 5 in the groove 31, which can achieve a good sealing effect. It is not necessary to design the sealing ring 5 as an inverted T-shape to increase the contact area with the upper edge 4. Furthermore, when transportation is required, the male and female buckles of the cover 2 and the thermal pack 1 can be connected together to lock the cover 2, preventing the cover 2 from being accidentally opened due to tipping over during the transportation of the thermal backpack. This, together with the magnetic components, provides a double insurance effect.
