TECHNICAL FIELD

[0001] The utility model relates to food packaging technical field, it is a kind of column cone composite food can. BACKGROUND

[0002] Food can is a kind of packaging container for being filled into food after certain treatment, generally tinplate can, after sealing sterilization, food in the can is isolated from outside, and microorganism is not polluted again, while most microorganisms (i.e. spoilage bacteria and pathogenic bacteria that can grow in the environment of can) are killed and enzyme is inactivated, so that the main reason causing food to deteriorate is eliminated, and it can be stored for a long time at room temperature.

[0003] The existing food can includes food can body, the inside of food can body is provided with placing cavity, the top of can body is provided with taking and placing opening, and the taking and placing opening is provided with can cover, and the top of can cover is fixedly connected with pull ring, when using, the can cover is taken off from the top of food can body by pull ring, and food in the placing cavity can be used.

[0004] But the filling of existing food and the manufacturing process of food can are separated, most food cans adopt metal three-piece can sealing form, the diameter of can body is equal (cylindrical), which leads to large floor area after the food can is made, increases the storage and management cost of food can, and the cylindrical can body also increases transportation cost when transporting to filling workshop. SUMMARY

[0005] The utility model provides a kind of column cone composite food can, overcome the above-mentioned prior art, it can effectively solve the problem that the existing food can exists large floor area and leads to the increase of storage cost and transportation cost.

[0006] The technical scheme of the utility model is realized by the following measures: a kind of column cone composite food can, including can body, can cover and can bottom, can body includes straight pipe section, first taper pipe section and second taper pipe section sequentially connected together from top to bottom, straight pipe section upper end and can cover outside seal fixed installation are installed together, second taper pipe section lower end and can bottom outside seal fixed installation are installed together, straight pipe section lower part is outwardly convex and then forms reinforcing rib, the taper of first taper pipe section is greater than the taper of second taper pipe section.

[0007] The following is further optimization or / and improvement to the above-mentioned utility model technical scheme:

[0008] The upper end of the above-mentioned straight pipe section can be outwardly extended to form a first outwardly turned edge, and the first outwardly turned edge and the outer side of the can cover are mutually engaged to form a first engagement structure.

[0009] The lower end of the aforementioned second conical tube section extends downward to form a second outward flange. The second outward flange interlocks with the outer side of the tank bottom to form a second interlocking structure. The outer diameter of the second interlocking structure is smaller than the outer diameter of the lower end of the second conical tube section.

[0010] The aforementioned second outward flange may include a conical segment, a cylindrical segment, an outward expansion segment, and a bent segment connected in sequence. The lower end of the second conical tube segment extends downward and contracts inward to form a conical segment that is larger at the top and smaller at the bottom. The lower end of the conical segment extends downward to form a cylindrical segment. The lower end of the cylindrical segment extends outward radially to form an outward expansion segment. The outer side of the outward expansion segment extends upward and contracts inward to form a conical bent segment that is smaller at the top and larger at the bottom. The outer diameter of the lower end of the bent segment is smaller than the outer diameter of the lower end of the second conical tube segment. The conical segment, cylindrical segment, outward expansion segment, and bent segment of the second outward flange, as well as the upper segment of the conical segment and the lower end of the second conical tube segment, all have smooth transitions.

[0011] The cross-section of the aforementioned reinforcing rib can be a trapezoid with a narrower outer edge and a wider inner edge, and both the upper and lower ends of the reinforcing rib are provided with rounded chamfers.

[0012] The can lid mentioned above can be an easy-open lid.

[0013] The diameter of the inner side of the upper end of the above straight pipe section is between 52.5mm and 155mm, and the distance between the upper end of the tank bottom and the lower end of the tank cover is between 39mm and 267mm.

[0014] This utility model has a reasonable and compact structure. During use, by setting the first conical tube section and the second conical tube section, multiple can bodies with can bottoms can be stacked together in sequence before food is filled, that is, before the can lid is fixedly installed with the can body. This saves the floor space occupied by the can bodies with can bottoms and reduces the company's inventory costs. At the same time, during transportation, for the same area, compared with cylindrical can bodies, multiple can bodies in this application can be stacked, increasing transportation capacity and reducing the transportation cost of transporting can bodies to the filling workshop.

Detailed Implementation

[0023] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0024] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0026] Example 1: As shown in the attached document Figures 1 to 7 As shown, the cylindrical-conical composite food can includes a can body, a can lid 1, and a can bottom 2. The can body includes a straight pipe section 3, a first conical pipe section 4, and a second conical pipe section 5 connected together from top to bottom. The upper end of the straight pipe section 3 is sealed and fixedly installed with the outside of the can lid 1, and the lower end of the second conical pipe section 5 is sealed and fixedly installed with the outside of the can bottom 2. The lower part of the straight pipe section 3 protrudes outward to form a reinforcing rib 6. The taper of the first conical pipe section 4 is greater than the taper of the second conical pipe section 5.

[0027] According to requirements, the cylindrical-conical composite food can, consisting of a can body, can lid 1, and can bottom 2, is a three-piece can structure. The can body, can lid 1, and can bottom 2 are made from tin-plated (or chrome-plated) thin steel sheets or aluminum alloy sheets through stamping. The can body is stamped into a rectangular sheet, and then the two ends are welded together using existing known techniques to form a cylindrical can body. The inner wall of the can body is expanded outward (expansion cone) to form the can body structure of this embodiment. The inner wall of the filling cavity formed by the can body, can lid 1, and can bottom 2 is coated with a known coating, which can ensure the quality of the product inside the filling cavity and improve the service life of the cylindrical-conical composite food can. The taper of the first conical tube section 4... The taper of the first tapered tube section 4 is greater than that of the second tapered tube section 5. The taper of the first tapered tube section 4 can be 8 to 12 degrees, and the taper of the second tapered tube section 5 can be 6 to 10 degrees. The taper of the first tapered tube section 4 is 2 degrees greater than that of the second tapered tube section 5. The height of the first tapered tube section 4 is greater than that of the second tapered tube section 5. The inner diameter of the upper end of the first tapered tube section 4 is the same as the inner diameter of the lower end of the straight tube section 3. The inner diameter of the lower end of the first tapered tube section 4 is the same as the inner diameter of the upper end of the second tapered tube section 5. Multiple bottom ribs 7 are pressed from the inside to the outside on the surface of the tank bottom 2. The cross-section of the bottom ribs 7 can be an arc shape with an upward opening, a V shape, or a trapezoid with a wider top and a narrower bottom. The surface of the bottom ribs 7 smoothly transitions to the surface of the tank bottom 2.

[0028] During use, by setting the first conical tube section 4 and the second conical tube section 5, multiple can bodies with can bottoms 2 can be stacked together before food is filled, i.e. before the can lid 1 is fixedly installed with the can body. This saves the floor space occupied by the can bodies with can bottoms 2 and reduces the company's inventory costs. At the same time, during transportation, for the same area, compared with cylindrical can bodies, multiple can bodies in this application can be stacked, increasing transportation capacity and reducing the transportation cost of transporting can bodies to the filling workshop.

[0029] The above-mentioned column-cone composite food can be further optimized and / or improved according to actual needs:

[0030] Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3 As shown in Figures 4, 6, and 7, the upper end of the straight pipe section 3 extends outward to form a first outward flange 8. The first outward flange 8 and the outer side of the can lid 1 interlock to form a first interlocking structure.

[0031] According to the requirements, the first outer flange 8 and the outer side of the can lid 1 interlock to form a first interlocking structure. The first interlocking structure is a known technology, such as a double-rolled edge structure or a triple-rolled edge structure, which facilitates the standardized production of column-cone composite food cans. Thus, after filling, the can lid 1 and the can body can be sealed and fixed together through the first interlocking structure.

[0032] Example 3: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2As shown, the lower end of the second tapered tube section 5 extends downward to form a second outward flange. The second outward flange interlocks with the outer side of the tank bottom 2 to form a second interlocking structure. The outer diameter of the second interlocking structure is smaller than the outer diameter of the lower end of the second tapered tube section 5.

[0033] According to the requirements, the second outer flange includes a conical segment 9, a cylindrical segment 10, an outward expansion segment 11, and a bent segment 12 connected in sequence. The lower end of the second conical tube segment 5 extends downward and contracts inward to form a conical segment 9 that is larger at the top and smaller at the bottom. The lower end of the conical segment 9 extends downward to form a cylindrical segment 10. The lower end of the cylindrical segment 10 extends outward radially to form an outward expansion segment 11. The outer side of the outward expansion segment 11 extends upward and contracts inward to form a conical bent segment 12 that is smaller at the top and larger at the bottom. The outer diameter of the lower end of the bent segment 12 is smaller than the outer diameter of the lower end of the second conical tube segment 5. The conical segment 9, the cylindrical segment 10, the outward expansion segment 11, and the bent segment 12 of the second outer flange, as well as the upper section of the conical segment 9 and the lower end of the second conical tube segment 5, all have smooth transitions. During use, the second outer flange and the outer side of the can bottom 2 interlock to form a second interlocking structure. The second interlocking structure is a known technology, such as a double or triple rolled edge structure. The outer diameter of the second interlocking structure is smaller than the outer diameter of the lower end of the second cone tube section 5. The can body and the can bottom 2 are sealed and fixed together through the second interlocking structure. In this way, multiple cylindrical cone composite food cans without can lids 1 can be stacked together in sequence, thereby reducing the floor space occupied by the cylindrical cone composite food can and also reducing transportation costs.

[0034] Example 4: As an optimization of the above examples, as shown in the appendix. Figure 1 , 4 As shown in Figures 6 and 7, the cross-section of reinforcing rib 6 is a trapezoid with a narrower outer edge and a wider inner edge. Both the upper and lower ends of reinforcing rib 6 are provided with rounded chamfers 13. During use, this design prevents excessive changes in the wall thickness of the straight pipe section 3 during the forming process, thus avoiding tearing. It also makes reinforcing rib 6 easier to form and facilitates the pouring of food, preventing food from accumulating at the corners of reinforcing rib 6 and reducing food waste. Furthermore, the design of reinforcing rib 6 makes it easier to grip the can body when pouring food, making operation more convenient.

[0035] Example 5: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3 As shown, can lid 1 is an easy-open lid. Depending on the requirements, can lid 1 can be a known easy-open lid, such as a pull-ring lid (PRT), a retaining easy-open lid (SOT), or a tear-off easy-open lid (FA). During use, the easy-open lid can be uniformly manufactured according to requirements, facilitating sealing after food is filled into the cone-shaped composite food can. The design of the easy-open lid also facilitates opening can lid 1, making it convenient to pour out the food from the cone-shaped composite food can.

[0036] Example 6: As an optimization of the above examples, as shown in the appendix. Figure 1As shown, the diameter of the inner side of the upper end of the straight pipe section 3 is between 52.5mm and 155mm, and the distance between the upper end of the tank bottom 2 and the lower end of the tank cover 1 is between 39mm and 267mm. This configuration allows for the fulfillment of various filling capacity requirements during use.

[0037] The above technical features constitute various embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
