Description
Technical Field
[0001] The utility model relates to the technical field of heat preservation ice bags, in particular to a heat preservation container structure which is convenient for storage. Background Art
[0002] Thermal insulation containers are made of thermal insulation materials in the shape of bags and boxes, and are often used to carry and keep food and medicine warm when going out. However, general thermal insulation containers are relatively large in size, and even if the container is empty, it will take up a large space, which is inconvenient to store or carry out, and the transportation cost is relatively high for manufacturers. For this reason, manufacturers hope to design the container into a foldable structure for easy folding and storage, but the texture of the thermal insulation material is relatively hard and not easy to fold. At the sides and bottom of the container where folding is required, the thermal insulation material must be cut into multiple parts, and the folding line is formed by sewing, resulting in the thermal insulation material on one side being disconnected and discontinuous, which may sacrifice the thermal insulation performance of a part of the container.
[0003] A possible solution to the above problem is to use a container with two layers, inner and outer layers, to ensure the thermal insulation effect through a double structure. However, under the premise that the container is foldable, another problem that may arise is that the thermal insulation container is different from conventional plastic parts that can be designed with a snap-on structure. After the folding structure of the inner and outer containers is unfolded, the surfaces cannot be relatively fixed. Especially when the internal space is not filled, there may be a lack of supporting force between the inner and outer containers. Once subjected to force, the container may be deformed, which may not only damage the items contained therein but also provide a poor user experience. Utility Model Content

[0042] refer to Figures 1 to 10 As shown, the utility model discloses a heat preservation container structure that is easy to store, including an outer container 1 and an inner container 2;
[0043] The outer container 1 includes a first body 11 and a first cover body 12, and the first body 11 and the first cover body 12 are filled with insulation material; the inner container 2 includes a second body 21 and a second cover body 22; the first body 11 and the second body 21 are both compressible and foldable structures, and the folding directions of the two are perpendicular to each other; in the unfolded state, the first cover body 12 is used to close the opening 110 of the first body 11, and the second cover body 22 is used to close the opening 210 of the second body 21.
[0044] Through the above scheme, the utility model is composed of an outer container 1 and an inner container 2, that is, the container has an inner and outer double-layer structure, which can provide a double thermal insulation effect, and at least the outer container 1 is filled with thermal insulation material, which can make the container have good thermal insulation performance. At the same time, since the items are generally placed in the inner container 2, the inner container 2 can be taken out when not storing items, which is convenient for cleaning; the first body 11 of the outer container 1 and the second body 21 of the inner container 2 are both compressible and foldable structures, which can reduce the occupied space when not in use and facilitate storage. When the containers are unfolded, since the folding directions of the two are perpendicular to each other, the non-folding surfaces of the two are no longer in the same direction, providing support force in the folding direction for each other, thereby ensuring that the container has a stable structure after unfolding, is not easily deformed by force, and improves user experience.
[0045] Specific embodiments of the present utility model are shown below.
[0046] Regarding the folding direction of the first body 11 and the second body 21 (based on the container being placed flat on the ground or a platform), it can be a combination of front-to-back folding and left-to-right folding, front-to-back folding and up-to-down folding, left-to-right folding and up-to-down folding, left-to-right folding and front-to-back folding, up-to-down folding and front-to-back folding, up-to-down folding and left-to-right folding, etc., so that the folding directions of the first body 11 and the second body 21 are not in the same direction and are perpendicular to each other. In this embodiment, the above-mentioned container is designed as a rectangular box shape as a whole, and the first body 11 is designed to be front-to-back compression folding, and the second body 21 is designed to be up-to-down compression folding, wherein the first body 11 adopts front-to-back compression folding, and the folding surface can be designed on the left and right sides and bottom surface of the outer container, and the area of these surfaces is small, which is easier to fold.
[0047] Further, see Figure 3 and Figure 4 The left and right sides of the first body 11 are sewn to form a folding line 111, and the folding line 111 is arranged along the up and down direction, so that the thermal insulation material in the left and right sides of the first body 11 is disconnected at the folding line 111 and divided into at least two foldable parts.
[0048] Secondly, the first cover 12 is connected to the rear side of the opening 110 of the first body 11 through the connecting piece 13, so that the first cover 12 can be directly folded to fit the rear side of the first body 11 when folded (see Figure 4 The whole is flatter, easier to package and store, and the first cover 12 does not need to be stored separately from the first body 11, so it is not easy to lose. In this embodiment, the opening periphery of the first body 11 and the periphery of the first cover 12 are respectively provided with a first retaining edge 112 and a second retaining edge 121, and the upper and lower sides of the connecting piece 13 are respectively connected to the lower edge of the outer wall behind the first retaining edge 112 and the upper edge of the outer wall behind the second retaining edge 121, so that the first cover 12 can be completely turned outward relative to the first body 11. When the first cover 12 is covered on the first body 11, the first retaining edge 112 is engaged with the second retaining edge 121 to achieve the sealing of the position of the connecting piece 13 (see Fig.10 status).
[0049] Also, see Figures 5 to 9 The second body 21 includes a bottom wall 211, a plurality of annular walls 212 disposed above the bottom wall 211, and a soft connecting wall 213 connected between adjacent annular walls 212. The bottom annular wall 212 is connected to the edge of the bottom wall 211, and the size of each annular wall 212 gradually decreases from top to bottom. The annular walls 212 or soft connecting walls 213 here are connected end to end to form a circle, and are not necessarily in the shape of a circular ring. In this embodiment, the bottom wall 211, the two annular walls 212 at the top and bottom, and the second cover body 22 are all made of PP (polypropylene), and the remaining annular walls 212 and soft connecting walls 213 are all made of TPE (thermoplastic elastomer).
[0050] The materials of the first body 11 and the first cover 12 are composed of a waterproof cloth on the outer layer, and aluminum-plated film, non-woven fabric, PP (polypropylene) board, pearl cotton, non-woven fabric and PEVA (polyethylene-vinyl acetate) arranged layer by layer in the waterproof cloth, wherein the aluminum-plated film is located on the outer side and the PEVA is located on the inner side. The material composition of the first body 11 and the first cover 12 can provide good thermal insulation performance.
[0051] A zipper 14 is provided between the opening of the first body 11 and the first cover 12 to reinforce the first body 11 and the first cover 12 after closing, and prevent the inner container 2 from loosening and falling. At the same time, since the outer container 1 cooperates with the inner container 2 to achieve a double heat preservation effect, and the inner container 2 has a second cover 22 to prevent internal hot air / cold air from leaking, the zipper 14 here can be an ordinary zipper 14, and there is no need to use a sealed zipper, which greatly reduces the cost of the product. In this embodiment, the zipper 14 uses an elastic chain cloth. When the zipper 14 is in a closed state, the chain cloth is tightened, which can cause the first cover 12 to be pulled downward, thereby making the second cover 22 and the second body 21 fit more tightly and have better sealing performance.
[0052] The first body 11 is provided with shoulder straps 15 on both sides for convenient extraction and movement of the heat preservation container. The shoulder straps 15 can be matched with the first body 11 by hooks for convenient disassembly when not in use.
[0053] The second cover 22 is sewn to the lower surface of the first cover 12 by sewing, so that the second cover 22 and the first cover 12 form an integral structure that can be opened and closed at the same time, and the user's operation of opening and closing the cover is simpler and more convenient. In this embodiment, the upper surface periphery of the second cover 22 is formed with a connecting edge 221 for sewing in a manner that protrudes upward; the upward connecting edge 221 makes it possible for the second cover 22 and the first cover 12 to not occupy the lateral space after being sewn, and there is no need to set a space for making way in the first body 11, so that the inner container 2 and the outer container 1 can fit more closely and are not easy to shake.
[0054] The lower surface of the second cover 22 is provided with a sealing convex ring 222 which is tightly matched with the opening 210 of the second body 21, so as to prevent the hot / cold air or liquid in the inner container 2 from leaking out through the tightly matched sealing method.
[0055] Furthermore, a sealing ring 23 is fixedly connected to the circumference of the sealing convex ring 222 to improve the sealing performance. The sealing ring 23 can be fixedly connected to the circumference of the sealing convex ring 222 by gluing or other methods.
[0056] At the same time, the upper surface of the second cover 22 is concavely formed with a plurality of grooves 223 corresponding to the position of the sealing convex ring 222. The position of the grooves 223 is designed as a hollow portion, which can reduce the weight and production cost of the second cover 22. In this embodiment, a plurality of ribs 224 are connected between the left and right side walls of the groove 223 to ensure the strength of the sealing convex ring 222 and the groove 223 after being hollowed out.
[0057] Secondly, the upper surface of the second body 21 is provided with a first step 214 located at the periphery of the opening 210, and the lower surface of the second cover 22 is provided with a second step 225 located at the periphery of the sealing convex ring 222. The first step 214 is attached to the second step 225, and the two realize surface contact sealing, which can be combined with the sealing ring 23 to realize the sealing between the second body 21 and the second cover 22, thereby the contact area between the sealing ring 23 and the inner wall of the second body 21 can be designed to be relatively small (for example, Fig.10 The sealing flange 231 in the middle), the friction force when opening the second cover body 22 is also relatively small, making it easier to open the second cover body 22.
[0058] An adsorbent 3 is provided between the inner wall of the opening 110 of the first body 1 and the outer wall of the second body 21, for achieving relative fixation between the first body 1 and the second body 21, so that the second body 21 fits more firmly in the first body 11, and will not shake when the user takes or places items even if there are fewer items in the second body 21. The adsorbent may be a magnet, Velcro, etc.
[0059] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
