Description
Technical Field
[0001] This utility model relates to the field of milk powder container technology, specifically to a milk powder can that is easy to fill. Background Technology
[0002] In recent years, with the continuous growth in market demand for infant formula and adult nutritional milk powder, filling efficiency and packaging convenience have become key issues in the production process. Traditional milk powder cans mostly adopt a cylindrical metal can structure, requiring manual or mechanical means to pour the milk powder into the can during filling. This process is prone to problems such as dust generation and insufficient filling accuracy, and some can designs are not conducive to high-speed filling on automated production lines. In addition, the opening size, internal wall structure, and sealing method of existing milk powder cans are often not optimized for the filling process, resulting in limited filling speed or high residual powder rate, affecting production efficiency and product quality.
[0003] To solve the above problems, there is an urgent need for a new type of milk powder can structure that optimizes the can geometry, filling interface and internal flow characteristics to achieve a fast, clean and high-precision filling process. Utility Model Content
[0004] This invention provides a milk powder can that is easy to fill. Because the can body adopts an elliptical cross section, its opening has a wider width than other cans of the same volume, which facilitates quick alignment and filling of the filling nozzle, reduces dust scattering, and improves production line speed.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a milk powder can that is easy to fill, comprising: a barrel body, wherein the barrel body has an elliptical cross-section, and a positioning seat is provided circumferentially near the top of the barrel body; a connecting seat is provided at one end of the positioning seat corresponding to the short axis of the barrel body cross-section, and a locking component is provided at the other end.
[0006] Preferably, the bottom ring of the positioning seat is provided with a groove in the circumference, and a plurality of first reinforcing plates are distributed at intervals inside the groove.
[0007] Preferably, the bottom of the barrel body is provided with an annular protrusion, and the outer wall of the barrel body is provided with a downwardly extending support edge, the bottom end of the support edge being flush with the bottom end of the annular protrusion; a second reinforcing plate is provided between the annular protrusion and the support edge.
[0008] Preferably, it also includes a top cover, which is adapted to the top of the barrel body, and the top cover is provided with a hinge connected to the positioning seat and a locking tongue that cooperates with the locking component.
[0009] Preferably, the bottom of the top cover is provided with a downwardly extending closed sleeve corresponding to the inner opening of the barrel body; the outer edge of the top of the barrel body and the outer edge of the bottom of the closed sleeve are respectively provided with rounded chamfers.
[0010] Preferably, the positioning seat is a slot structure, the bottom end of the hinge is connected to the positioning seat through a plug plate, and the bottom end of the plug plate is provided with a hook that cooperates with the inside of the positioning seat.
[0011] Preferably, the top cover, the hinge, and the insert plate are an integral plastic structure, and the hinge axis of the hinge is arc-shaped.
[0012] Preferably, the locking component is a hook structure, and the positioning seat is provided with an anti-theft lock plate on the outside of the locking component.
[0013] The beneficial effects of this utility model are as follows: The barrel body adopts an elliptical cross-section, and its opening has a wider width than other cans of the same volume, thus facilitating rapid alignment and filling of the filling nozzle, reducing dust dispersion, and increasing production line speed. On automated filling lines, this elliptical barrel body makes it easier to achieve precise positioning through directional arrangement, thereby reducing the risk of can jamming and making it more suitable for high-speed filling equipment. The connecting seat and locking components are used to install and fix the top cover during the later packaging of milk powder. The groove design of the positioning seat not only reduces the consumption of raw materials by the barrel body but also ensures the strength of the positioning seat. The annular protrusion at the bottom of the barrel body increases the strength of the barrel body and avoids the problem of bottom deformation when the barrel body is fully loaded, while the supporting edge improves the appearance of the barrel body, and the second reinforcing plate further improves the strength of the bottom of the barrel body. The top cover is connected to the barrel body by a hinge and locked with a locking tongue, thereby ensuring the reliability of the product packaging. The sealing sleeve can fit tightly with the top opening of the barrel body after the top cover is closed, thereby achieving a sealing effect, and the design of two sets of rounded corners ensures that the top cover opens and closes smoothly and freely. When the top cover is open or closed, the hinge yields and deforms due to the elasticity of its material, thus achieving a self-positioning effect. The anti-theft lock plate is connected to the positioning seat through a one-time connection structure to restrain the lock tongue, thereby ensuring the security of the finished product during the sales stage after filling and effectively preventing unauthorized disassembly.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a milk powder can that is easy to fill includes: a barrel body 1, the barrel body 1 having an elliptical cross-section, and a positioning seat 2 being provided circumferentially near the top of the barrel body 1; the positioning seat 2 having a connecting seat 3 at one end corresponding to the short axis of the cross-section of the barrel body 1, and a locking component 4 at the other end.
[0022] Through the above design, the barrel body 1 adopts an elliptical cross-section, which has a wider opening than other cans of the same volume. This facilitates quick alignment and filling of the filling nozzle, reduces dust scattering, and increases production line speed. On automated filling lines, this elliptical barrel body 1 is easier to position precisely through directional arrangement, thus reducing the risk of can jamming and making it more suitable for high-speed filling equipment. The connecting seat 3 and locking component 4 are used to attach and fix the top cover 9 during the later packaging of the milk powder.
[0023] The bottom ring of the positioning seat 2 is provided with a groove in the circumference, and multiple first reinforcing plates 5 are distributed at intervals inside the groove.

[0025] The bottom of the barrel body 1 is provided with an annular protrusion 6, and the outer wall of the barrel body 1 is provided with a downwardly extending support edge 7, the bottom end of the support edge 7 being flush with the bottom end of the annular protrusion 6; a second reinforcing plate 8 is provided between the annular protrusion 6 and the support edge 7.
[0026] With this design, the annular protrusion 6 at the bottom of the barrel 1 increases the strength of the barrel 1 and avoids the problem of bottom deformation when the barrel 1 is fully loaded, while the support edge 7 improves the appearance of the barrel 1, and the second reinforcing plate 8 further increases the strength of the bottom of the barrel 1.
[0027] It also includes an upper cover 9, which is adapted to the top of the barrel body 1, and the upper cover 9 is provided with a hinge 10 connected to the positioning seat 2, and a locking tongue 11 that cooperates with the locking component 4.
[0028] With this configuration, the top cover 9 is connected to the barrel body 1 via the hinge 10 and locked using the locking tongue 11, thereby ensuring the sturdiness of the product packaging.

[0033] The top cover 9, the hinge 10, and the insert plate 13 are an integral plastic structure, and the hinge axis of the hinge 10 is arc-shaped.
[0034] With this setting, when the top cover 9 is open or closed, the hinge 10 yields and deforms due to the elasticity of its own material, thereby achieving a self-positioning effect.
[0035] The locking component 4 is a lock hook structure, and the positioning seat 2 is provided with an anti-theft lock piece 14 on the outside of the locking component 4.
