Description

Technical Field

[0001] This utility model relates to the field of packaging barrel technology, and in particular to a multifunctional packaging barrel sealing cap. Background Technology

[0002] In the storage and transfer of liquid media such as industrial lubricating oil and hydraulic oil, metal or plastic transfer containers are widely used. These transfer containers typically have a sealed end cap structure at the outlet to seal the liquid, and a corresponding sealing cap is attached to the sealed end cap. The main function of the sealing cap is to provide waterproofing, dustproofing, and leak prevention, and can also be printed with the company's logo. Before use, the sealing cap must be opened to facilitate the opening of the sealed end cap and the pouring of the liquid media.

[0003] To facilitate operation, the existing technology generally adopts the easy-tear sealing cap structure, but there are significant technical defects in its actual application, which are manifested in the following aspects: (1) There are defects in the mechanical design of the tearing structure. The existing easy-tear sealing caps mostly adopt the pre-indentation tear strip structure, which forms the fracture guide line by locally thinning the material. However, since the sealing cap of the transfer barrel needs to withstand the transportation vibration and stacking load, in order to ensure the sealing performance, the overall thickness of the cap is large, resulting in the actual breaking strength of the tear strip being too high, causing difficulty in opening the cap; or the cap is partially damaged during the opening process, which cannot achieve a good opening effect. (2) The existing tear strip ends are not provided with anti-slip texture or grip, and the fingers are easy to slip during operation, which leads to sudden force causing the hand to collide with the edge of the barrel; or the gloves or skin of the operator are easily torn during the handling of the packaging barrel. (3) In order to improve the sealing performance of the sealing cap, the existing technology generally adopts the extrusion process to combine the sealing cap and the sealing end cap of the barrel mouth into one piece. When tearing, a large bonding force needs to be overcome, which causes the tearing path to deviate and break. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figures 1-12 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] Example 1: As Figure 3 , Figures 5-7 As shown, this utility model discloses a multifunctional packaging barrel sealing cap. The packaging barrel 1 is provided with a barrel opening 2 and a sealing end cap 3 connected inside the barrel opening 2. A sealing cap 4 is pressed onto the sealing end cap 3. An easy-tear area 5 is formed on the sealing cap 4 through a fracture guide line. The easy-tear area 5 extends radially along the sealing cap 4 to both ends of the cap body. The traction member 7 includes two members that are respectively riveted, welded, or integrally formed with both ends of the easy-tear area 5. Figure 3 and Figures 6-7 As shown, the traction component 7 is either a pull tab or a movable ring, which is fixed by riveting the connecting end 6 connected to the tear-off area 5; as Figure 5 As shown, the traction component 7 and the easy-tear area 5 are integrally molded. During operation, the sealing cap 4 and the sealing end cap 3 can be quickly and efficiently separated by tearing with the traction component 7. Moreover, the traction component 7 has a non-sharp structure, which can effectively prevent the packaging barrel 1 from scratching gloves or skin during transportation.

[0020] Example 2: As Figure 2 As shown, the difference from Embodiment 1 is that the traction member 7 includes one that is riveted, welded, or integrally formed with one end of the easy-tear area 5. For example... Figure 3 and Figures 5-6 As shown, only one traction component 7 needs to be connected to one end of the easy-tear area 5 to meet the requirements.

[0021] Example 3: As Figure 4 , Figure 8 and Figure 10 As shown, the difference from Embodiment 1 and Embodiment 2 is that in this embodiment, the traction member 7 is not connected to one or both ends of the easy-tear area 5, but is connected to the top of the easy-tear area 5 by riveting or welding.

[0022] Example 4: Combination Figure 2 and Figure 11 As shown, the tear-off area 5 structure differs from that in Embodiment 1 in that the tear-off area 5 extends radially along the sealing cap 4 to one end of the cap body, and the other end of the tear-off area 5 extends to the circumference of the top surface of the cap body. In this embodiment, the traction member 7 includes one that is riveted, welded, or integrally formed with the easy-open end of the tear-off area 5. The specific arrangement of the traction member 7 is consistent with that in Embodiment 2, and will not be described again.

[0023] Example 5: Combination Figure 4 , Figure 8 and Figure 11 As shown, the difference from Embodiment 4 is that the traction member 7 in this embodiment is riveted or welded to the top of the tear-off area 5. The arrangement of the traction member 7 in this embodiment is the same as that in Embodiment 3, the difference lies in the arrangement of the tear-off area 5 in the two embodiments.

[0024] Example 6: As Figure 12 As shown, the difference from Embodiments 1 to 5 is that in this embodiment, the break guide line is a semi-circular structure arranged along the outer circumference of the sealing cap 4, with an opening extending to the edge of the sealing cap. A traction member 7 is correspondingly provided at the top of the easily tearable area 5 formed therefrom. It should be noted that the type of break guide line used in the easily tearable area 5 is not limited here, as long as it is laid out as required.

[0025] Example 7: As Figure 4 and Figure 8 As shown, the traction component 7 is connected to the top of the easy-tear area 5. The placement of the traction component 7 occupies a certain height, causing the clamps adapted to the sealing cap 4 to be unable to properly connect the sealing cap 4 to the sealing end cap 3. To meet the requirement of fixing the sealing cap 4, the depth of the original clamps needs to be adjusted to achieve the fixed installation of the sealing cap 4. In this embodiment 7, a recessed area 8 is provided at the top of the sealing cap 4, and the traction component 7 is connected to the recessed area 8. This recessed area 8 ensures that the top surface of the traction component 7 is equal to or less than the height of the top surface of the sealing cap 4, thus eliminating the need to adjust the original clamps to complete the fixed connection of the sealing cap 4. It should be noted that the recessed area 8 can be smaller than the coverage area of ​​the easy-tear area 5 (e.g., ...). Figure 9 (As shown), it can also be larger than the area covered by the tear-off zone 5, that is, the breakage guide line passes through the sinking zone 8.

[0026] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
