Description

Technical Field

[0001] This utility model relates to the field of packaging containers, and more particularly to a packaging can. Background Technology

[0002] With the continuous increase in market demand, various types of outer packaging are also increasing. In the pharmaceutical, food and daily chemical product industries, packaging cans are often used for packaging and sealing. The lid and the can body are usually connected by threads to achieve the detachable installation of the lid, which can repeatedly open or close the packaging can to avoid leakage.

[0003] However, when using this type of packaging can with a separate can body and lid, the lid needs to be unscrewed to remove the material, which is inconvenient and the disassembled lid is easy to lose. Secondly, when screwing the lid back on, improper fit between the lid and the can body is common, resulting in poor sealing and leakage.

[0004] Some packaging cans, based on the original threaded connection of the lid, have an additional flip-top integrated at the top of the lid, giving it the function of being opened by flipping.

[0005] The above-mentioned technology solves the problem of inconvenient bottle cap opening. This utility model also provides a new technical solution to solve the above-mentioned problem. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses a packaging can, referring to... Figures 1-6 As shown, it mainly includes a tank body 1, a cover body 2, and a sealing element 3. The tank body 1 includes a tank opening 11. The sealing element 3 is nested and installed on the cover body 2. The cover body 2 is threaded to the outer periphery of the tank opening 11 and is sealed by the sealing element 3.

[0030] Reference Figure 1 and Figure 2As shown, an opening 22 is provided on the lid 2 relative to the mouth 11 of the can, and the opening 22 can connect to the interior of the can 1. A groove 23 is provided on the upper end face 27 of the lid 2. The groove 23 is arranged horizontally through the can, and the opening 22 is located at the center of the groove 23. An upper end cap 21 is integrally connected to one end of the groove 23. The upper end cap 21 can be folded and fitted into the groove 23 relative to the lid 2, so that the upper end face 215 of the upper end cap 21 is roughly flush with the upper end face 27 of the lid 2, improving the overall fit between the lid 2 and the upper end cap 21. The upper end cap 21 and the lid 2 are integrally connected by flexible plastic, which can be repeatedly folded to open the upper end cap 21 and fasten it into the groove 23 on the lid 2. The operation is simple and the material is easy to remove.

[0031] Reference Figure 3 and Figure 4 As shown, an annular boss 3 222 is integrally connected to the lower end of the opening 22 inside the cover 2. The inner circumference of the annular boss 3 222 is threaded to the outer circumference of the can mouth 11. An annular boss 221 is provided on the upper outer circumference of the cover 2 located at the opening 22. An annular boss 1 211 is provided on the upper cover 21 relative to the opening 22. The sealing member 3 is sleeved on the outside of the opening 22, that is, the sealing part 1 31 is embedded in the inner circumference of the cover 2 and tightly fits the lower end of the opening 22, and the sealing part 2 32 is sleeved on the annular boss. The outer side of the second 221 is integrally connected with the sealing part 31 to form a state that completely covers the opening 22; when the cover 2 is threaded to the outer periphery of the can opening 11, the sealing part 31 abuts between the cover 2 and the end of the can opening 11, realizing a sealed connection between the cover 2 and the can 1; the outer periphery of the annular boss 211 on the upper cover 21 can be embedded into the inner periphery of the opening 22 and abut against the sealing part 32 sleeved on the outer side of the opening 22, realizing a sealed connection between the upper cover 21 and the cover 2.

[0032] Reference Figure 4 As shown, since the packaging can is mainly opened and closed by opening and closing the upper end cover 21, in order to enhance the sealing effect and ensure the sealing performance between the upper end cover 21 and the cover body 2, firstly, conical surfaces 212 and 321 are respectively opened on the outer periphery of the annular boss 211 and the inner periphery of the sealing part 32 sleeved on the annular boss 221. The conical surfaces 212 and 321 can press against each other to enhance the sealing effect. Secondly, two annular protrusions 213 are opened on the outer periphery of the annular boss 211 of the upper end cover 21. When the upper end cover 21 is fully fastened to the cover body 2, the outer periphery of the annular boss 211 abuts against the inner periphery of the sealing part 32 on the opening 22, while the annular protrusions 213 can press against the upper end of the sealing part 32 to form a secondary seal on the opening 22, enhance the sealing effect, and improve the overall sealing performance of the packaging can.

[0033] Reference Figure 5and Figure 6 As shown, one end of the upper cover 21 is integrally connected to the cover body 2 via flexible plastic, and the inner side of the other end is provided with a second protrusion 214. On the cover body 2, a first protrusion 26 is provided at a position opposite to the second protrusion 214. The second protrusion 214 and the first protrusion 26 can form a snap-fit, so that the upper cover 21 can be folded and closed onto the cover body 2. A limiting groove 24 is provided on the outer periphery of the cover body 2 and below the first protrusion 26. The upper end of the limiting groove 24 is inclined toward the inside of the cover body 2, which can leave enough gap for opening the upper cover 21 for convenient operation.

[0034] Reference Figure 6 As shown, inside the limiting groove 24, a through hole 25 is provided below the protrusion 26 on the cover 2. A connecting part 33 is integrally connected to the outer circumference of the sealing part 32. The connecting part 33 can pass through the through hole 25 and be integrally connected to the fixing part 34. The outline of the fixing part 34 matches the inner circumference of the limiting groove 24 on the cover 2, and can be completely embedded in the limiting groove 24 and fit tightly. When the upper cover 21 is opened upward by hand, the fingers press against the outer surface of the fixing part 24, which can enhance the comfort. Since the fixing part 24 is embedded and integrally connected to the sealing part 32 through the connecting part 33, the installation stability of the sealing part 3 can be effectively improved.

[0035] The cover 2 is made of hard plastic, while the sealing part 31, sealing part 32, connecting part 33, and fixing part 34 are all made of soft silicone or rubber. The sealing part 31, sealing part 32, connecting part 33, and fixing part 34 are integrally formed. The sealing element 3 is embedded in the cover 2, and the sealing element 3 and the cover 2 are integrally formed. The connecting part 33 on the sealing element 3 passes through the through hole 25 on the cover 2, so that the sealing part 31 and sealing part 32 of the sealing element 3 and the fixing part 34 embedded in the peripheral limiting groove 24 of the cover 2 form an integral connection, which can enhance the connection strength and sealing performance between the sealing element 3 and the cover 2.
