Description

M259780 IV. Creation Instructions α) [Technical Field to which the New Type belongs] This creation relates to an improved structure of a thermal insulation barrel, in particular a thermal insulation of the inner and outer barrel walls, so that the internal insulation material is not easily leaked from the joint. Improved barrel structure. [Prior art] As shown in FIG. 8, it is a common insulation bucket, which mainly includes an inner bucket 81 with a closed bottom and an outer bucket 8 2 with a top and a bottom communicating with each other. The inner bucket 81 is placed in the Inside the outer bucket 8 2, a bottom cover 8 5 is closed at the bottom of the outer bucket 8 2, so that the outer bucket 8 1 and the inner bucket 8 2 and the bottom cover 8 5 form a containing space 8 that can be filled with a heat-insulating material. 3, and the accommodating space 8 3 is covered with a ring cover 8 4 at the openings on the tops of the inner and outer barrels 8 1 and 8 2 to seal the accommodating space 8 3 and fill the accommodating space. 8 The insulation material inside 3 will not leak out. In order to prevent the thermal insulation material in the accommodating space 8 3 from leaking out, the ring cover 8 4 and the bottom cover 8 5 are welded to the inner and outer barrels 8 1 and 8 2 to seal the accommodating space. Space 8 3. However, when the inner and outer barrels 8 1 and 8 2 are produced, they are rolled into a barrel shape with a long rectangular metal plate, and the two ends of the curl are overlapped to form an overlapping section A, as shown in FIG. 9. As shown in the figure, the overlapped section A is welded and fixed to form a round barrel. In this way, the inner and outer barrels 8 1 and 8 2 will form a height difference at the overlapped section A, resulting in the inner and outer sections. The barrel walls of the barrels 8 1 and 8 2 are not flat enough. As far as the appearance of the outer barrel 8 2 is concerned, the barrel body is not flat and beautiful, and the quality of the product is lowered. As for the interior of the inner barrel 8 1, it is easy to be in the overlapping section. Dirt and dirt are stored in A, and the problem of poor hygiene occurs, especially in the inner bucket 8 1

M259780 Fourth, the creation instructions (2) for food packaging, therefore, it is particularly important that the inner bucket 81 can be kept clean and hygienic. In addition, when the ring cover 8 4 and the bottom cover 85 are welded to the inner and outer buckets 8 1 and 82, unevenness will be generated at the overlapping section A of the inner and outer buckets 8 1 and 82, as in the first section. As shown in Fig. 0, it will not only affect the appearance of the appearance, but also cause poor adhesion during welding due to the difference in the overlapping section A, resulting in leakage of the insulation material in the accommodating space 83. The outer barrels 8 1 and 8 2 and the ring cover 8 4 and the bottom cover 85 are made of stainless steel metal material, but the iron steel is harder and has no shrinkage. Therefore, the ring cover 8 4 is welded with When the bottom cover is 85, it is not easy to weld tightly at the overlapping section A. If the quality control is not strict enough, it is very easy to cause the insulation material to be filled by the inner and outer barrels 8 1 and 8 2 when filling the insulation material. The joint between the section A and the bad cover 8 4 and the bottom cover 85 seeps out, which causes the filling of the thermal insulation material to be inaccurate, thereby reducing the thermal insulation effect of the thermal insulation barrel. Therefore, the lack of flatness of the barrel wall caused by the above-mentioned conventional thermal insulation barrel structure has always been necessary to improve the lack of aesthetics and the lack of hygienic and thermal insulation materials. [New content] The main purpose of this creation is to provide an improved structure of a thermal insulation barrel, which mainly includes an outer barrel, an inner barrel accommodated in the outer barrel, a combination of the outer barrel and the A ring cover at the top of the inner bucket and a cover coupled to the bottom of the outer bucket form a closed accommodation space between the outer bucket, the inner bucket, the ring cover and the lid, wherein the outer bucket is a long rectangular The metal sheet is curled into the top and the bottom is hollow

M259780 Fourth, the creative description (3) of the barrel shape, the opposite ends of the curl are butt jointed to form a flat joint section, and the top and bottom ends of the outer barrel respectively have a first flange extending outward And the second flange; the inner barrel is rolled into a barrel shape by a long rectangular metal material plate, and the two opposite ends of the curl are connected in a butt joint manner to form a flat joint section, and is closed at the bottom end of the inner barrel. Bottom; the ring cover has a through hole communicating with the inner barrel, and the peripheral edge of the through hole extends downwards, and the extension is fixed to the peripheral wall near the top of the inner barrel, and the outer edge of the ring cover corresponds to The first flange at the top of the outer barrel has a crimping portion. After the crimping portion is attached to the first flange of the outer barrel, the crimping portion is folded inward together with the first flange portion, and The outer edge of the ring cover is tightly fixed to the outer barrel; the second edge of the outer edge of the cover corresponding to the bottom end of the outer barrel has a curling portion, and the curling portion is connected to the second edge of the outer barrel After the flanges are attached, the curled portion is folded inwardly together with the second flange portion, and the outer edge of the cover is folded. It is fixed tightly with the outer barrel. Because the joint sections of the outer bucket and the inner bucket are connected in a butt joint manner, the wall of the outer bucket and the inner bucket are leveled, and there is no difference in height between the overlap of the walls of the conventional bucket. Thus, for the outer bucket, The appearance is relatively flat and beautiful, which can improve the overall quality, and the flat inner wall of the inner barrel is easy to clean, and it is not easy to hide dirt and dirt, which helps to improve sanitary quality. The second purpose of this creation is that when the ring cover and the outer edge of the cover are folded and fixed with the outer bucket, the joint section of the outer bucket is flat, and there will be no unevenness at the joint section. To make it fit tightly when rolled, and

M259780 Fourth, creation instructions (4) When the extension of the ring cover and the inside, make the welding tightly, and make the accommodation space; without the problem of leakage of insulation materials. The effect is better than the other purpose of this creation, which is that the outer barrel is joined, and the material used to overlap the barrel body can be saved: the cost of the barrel blessing material, and it is smoother to fold with a crimping machine, which is not easy [Embodiment] Abrasion of the jig when the hemming is rotated. Please refer to Figure 1 to Figure 6, the middle and the examples, this is for illustration purposes only. Three strikes The factory, the choice for this creative limitation. The patent application is not subject to this example. The creative department is a kind of improved insulation barrel structure, which is placed in the outer barrel 1; there is an outer barrel! The bottom of the ring cover 3 and the cover 4 to make it; between the cover 3 and the cover 4 of the outer barrel 1 to form a closed container S 丄, inner barrel 2, warm material, among which; ' For filling, the outer barrel 1 is formed by a long rectangular 厶 pole ku 〈metal 枓 plate rubbing point ^. The shape of a barrel is curled relative to A ^ A ....... two tops and bottom ends Penetration :: = roll = :: end system is connected by butt joint to form the joint section 1 i, as shown in Figure 2 A, in practice, the female is formed into a flat joint section 11 and the joint is equivalently joined by welding. In this example, the connection has an outwardly extending first flange i 2 and a first top and a bottom end for combining the ring cover 3 and the cover 4, respectively. The flange is rolled into a barrel shape with the inner bucket 2 also with a long rectangular metal

M259780 M259780 Fourth, creation instructions (6) ----______ The appearance of barrel 1 is relatively flat and beautiful, while the flat inner wall of barrel 2 is easy to clean, and Z improves the overall quality, and the interior quality is improved. It is easy to hide dirt and stains, which helps sanitary products. Moreover, the ring cover 3 and the cap timing, because the joint section 丄 1 ^ 2 edge of the outer bucket 1 and the outer bucket 1 are folded and fixed 1 produce unevenness. In the situation, such as = whole, but will not be in good contact at the joint section, and the extension section of the ring cover 3 ^ 7 shown in the figure, when it is rolled, because the joint section 2 of the inner barrel 2 1 flat ^ 1 1 when welding with the inner barrel 2, the sealing effect of the accommodating space 5 is good, and the welding tightness is good, and the problem of leakage is caused. Except that the outer barrel 1 and the inner barrel omits the materials used for overlapping joints of the conventional barrel body, and the crimping machine 3 is used to fold the ring cover 3 and the joint section 1 of the outer barrel 1 is flat. For the sake of smoothness, it is not easy to cause the disclosure of the above-mentioned embodiment of the crimping machine to restrict the creation, so any change in the numerical value belongs to the scope of the creation. The 2 is joined in a butt joint manner, but can relatively reduce the cost of materials. When the cover 4 and the outer barrel 1 are worn, the crimping machine is more abrasive than the jig when rotating the crimping. For the purpose of explaining this creation, it is not intended to replace or replace the equivalent components, but the above detailed description can indeed achieve the aforementioned purpose, and apply. To enable those skilled in the art to know that this creation has actually complied with the provisions of the Patent Law,
