Description

Technical Field

[0001] This application relates to the field of sealing structures for fluorinated barrels, and in particular to a highly airtight fluorinated barrel. Background Technology

[0002] Packaging containers, an indispensable part of modern industry and daily life, directly impact product quality and safety through their sealing performance. With the rapid development of the packaging industry, various types of packaging containers are widely used in food, chemical, and pharmaceutical fields. In these sectors, the sealing performance of containers not only affects product shelf life and transportation safety but also significantly impacts environmental protection and user experience. Especially in globalized logistics networks, packaging containers need to adapt to various complex transportation environments, placing higher demands on sealing technology.

[0003] Currently, most containers on the market are made of plastic, and their sealing performance is mainly achieved through the tight fit between the lid and the opening. However, these conventional designs often experience a decrease in the sealing strength of the container opening—the seal between the lid and the opening—when faced with low air pressure at high altitudes or extreme climatic conditions. Utility Model Content

[0004] To improve the sealing performance of packaging containers under extreme conditions, this application provides a high-sealing fluorinated drum.

[0005] The high-sealing fluorinated tank provided in this application adopts the following technical solution:

[0006] A high-sealing fluorinated drum includes a drum body and a drum lid. The top of the drum body has a drum opening ring that mates with the drum lid. The outer wall of the drum opening ring is provided with a threaded section, and the inner wall of the drum lid is provided with a threaded groove that mates with the threaded section. The thread width of the threaded section is 2.5 mm.

[0007] By adopting the above technical solution, the fit between the threaded section and the threaded groove can achieve a tight connection between the lid and the mouth ring. The 2.5mm thread width design ensures the strength and stability of the threaded connection, thereby improving the sealing performance of the fluorinated drum under normal conditions.

[0008] Preferably, the upper side of the threaded section includes an upper chamfer, and the lower side of the threaded section includes a lower chamfer. The angle of the lower chamfer is 10°, and the thread groove is formed in conjunction with the upper and lower chamfers of the threaded section.

[0009] By adopting the above technical solution, an upper chamfer is provided on the upper side of the threaded tooth, and a lower chamfer is provided on the lower side, with the lower chamfer angle being 10°. The thread groove is formed in conjunction with the upper and lower chamfers of the threaded tooth, which can effectively improve the tightness of the threaded connection. The angle of the lower chamfer of the threaded tooth enhances the sealing of the prepared container, reducing the probability of a decrease in sealing strength under conditions of low air pressure at high altitudes or extreme climates. This design reduces stress concentration during thread engagement, improves the stability of the threaded connection, and thus enhances the sealing performance between the lid and the mouth ring, maintaining good sealing strength even under extreme conditions.

[0010] Preferably, the inner wall of the bucket lid is provided with a snap-fit ​​strip, the snap-fit ​​strip is horizontally positioned, the snap-fit ​​strip is located at the tail end of the threaded groove near the bucket body, and the bucket lid is screwed onto the bucket mouth ring so that the snap-fit ​​strip abuts against the bucket mouth ring.

[0011] By adopting the above technical solution, the snap-fit ​​strip ensures that when the lid is screwed onto the barrel opening ring, the horizontally positioned snap-fit ​​strip abuts against the ring, thereby increasing the contact area and pressure between the lid and the barrel body, and improving the overall structural stability. This design effectively enhances the sealing performance at the connection between the lid and the barrel body, especially under extreme environmental conditions, reducing the risk of seal failure due to changes in external pressure.

[0012] Preferably, the snap-fit ​​strip is an arc-shaped strip, and the width at both ends of the snap-fit ​​strip along its length is smaller than the width at the middle of the snap-fit ​​strip.

[0013] By adopting the above technical solution, the arc-shaped strip design of the snap-fit ​​strip can better fit the top wall of the barrel, increasing the contact area and thus enhancing the sealing performance between the lid and the barrel body. Furthermore, the design where the width at both ends of the snap-fit ​​strip is smaller than the width in the middle reduces material usage and manufacturing costs while ensuring structural strength. It also facilitates the snap-fit ​​strip's easy positioning and contact with the top wall of the barrel during assembly, further improving the overall sealing effect and assembly efficiency.

[0014] Preferably, there is a distance between the end of the snap-fit ​​strip near the end of the threaded groove and the end of the threaded groove, that is, the vertical intersection line of the snap-fit ​​strip near the end of the threaded groove is parallel to the vertical intersection line between the end of the threaded groove and the end of the threaded groove.

[0015] By adopting the above technical solution, a distance is set between the snap-fit ​​strip and the end of the threaded groove, allowing for some adjustment space during the tightening process of the lid. This prevents the snap-fit ​​strip from prematurely contacting the end of the threaded groove due to manufacturing errors, thus avoiding affecting the smoothness of tightening. Simultaneously, this design ensures that when the lid is fully tightened, the snap-fit ​​strip accurately abuts against the top wall of the bucket, thereby improving the sealing performance and connection reliability between the lid and the bucket neck ring.

[0016] Preferably, a sealing gasket is provided on the bottom wall of the inner cavity of the bucket lid, and the sealing gasket can abut against the end of the bucket mouth ring near the bucket lid.

[0017] By adopting the above technical solution, the sealing gasket can effectively improve the sealing performance between the lid and the mouth ring. Specifically, the sealing gasket abuts against the end of the mouth ring closest to the lid, forming a preliminary sealing structure, reducing the possibility of gas or liquid leakage between the two, thereby improving the overall sealing effect of the container.

[0018] Preferably, a sealing ring is provided on the end wall of the sealing gasket near the barrel opening ring, the sealing ring protruding from the sealing gasket, and the sealing ring can abut against the side wall of the barrel opening ring away from the barrel body.

[0019] By adopting the above technical solution, a sealing ring is set on the end wall of the sealing gasket near the barrel opening ring, and the sealing ring protrudes from the sealing gasket, allowing the sealing ring to abut against the side wall of the barrel opening ring away from the barrel body. This creates a double-sealing structure when the barrel lid is tightened to the barrel body. This design significantly enhances the sealing performance of fluorinated barrels under extreme conditions, effectively prevents leakage of contents, and improves product reliability and safety.

[0020] Preferably, the end of the barrel opening ring near the barrel lid is provided with an arc-shaped contact surface, which simultaneously abuts against the sealing ring and the sealing gasket.

[0021] By adopting the above technical solution, the arc-shaped contact surface design can effectively increase the contact area between the sealing ring and gasket and the barrel mouth ring, thereby improving sealing performance. Under extreme conditions, the arc-shaped contact surface can better adapt to the deformation between the barrel mouth ring, sealing ring, and sealing gasket, ensuring a tight fit between the three and further reducing the risk of leakage. In addition, the arc-shaped contact surface simplifies the assembly process of the sealing structure and improves assembly efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The fit between the threaded section and the threaded groove enables a tight connection between the lid and the mouth ring. The 2.5mm thread width design ensures the strength and stability of the threaded connection, thereby improving the sealing performance of the fluorinated drum under normal conditions.

[0024] 2. The upper side of the threaded tooth is chamfered, and the lower side is chamfered, with a 10° angle. The thread groove is designed to align with the upper and lower chamfers of the threaded tooth, effectively improving the tightness of the threaded connection. The angle of the lower chamfer enhances the sealing of the container, reducing the likelihood of decreased sealing strength under conditions of low air pressure at high altitudes or extreme weather. This design reduces stress concentration during thread engagement, improving the stability of the threaded connection and thus enhancing the sealing performance between the lid and the mouth ring, maintaining good sealing strength even under extreme conditions.

[0025] 3. The snap-fit ​​strip design allows the lid to be screwed onto the barrel opening ring, where the horizontally positioned snap-fit ​​strip abuts against the top wall of the barrel, increasing the contact area and pressure between the lid and the barrel body, thus improving the overall structural stability. This design effectively enhances the sealing performance at the connection between the lid and the barrel body, especially under extreme environmental conditions, reducing the risk of seal failure due to changes in external pressure.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a highly airtight fluorinated tank. (Refer to...) Figure 1 and Figure 2A high-sealing fluorinated barrel includes a barrel body 1 and a barrel lid 2. The top of the barrel body 1 is integrally formed with a barrel mouth ring 11, which communicates with the internal cavity of the barrel body 1. The outer wall of the barrel mouth ring 11 is integrally formed with a threaded section 12 by a mold. The inner wall of the barrel lid 2 is provided with a threaded groove 21 corresponding to the threaded section 12, and the barrel lid 2 can be screwed onto the barrel mouth ring 11.

[0033] Reference Figure 2 and Figure 3 To enhance the sealing strength between the barrel opening ring 11 and the barrel lid 2, the thread width of the threaded section 12 is 2.5 mm. The upper side of the threaded section 12 includes an upper chamfer 121, and the lower side includes a lower chamfer 122 with an angle of 10°. The thread groove 21 is formed to mate with the upper chamfer 121 and the lower chamfer 122 of the threaded section. This effectively improves the tightness of the threaded connection. The angle of the lower chamfer 122 enhances the sealing strength of the prepared container, reducing the likelihood of a decrease in sealing strength under conditions of low air pressure at high altitudes or extreme climates.

[0034] Reference Figure 2 and Figure 4 The inner wall of the lid 2 is integrally formed with a snap-fit ​​strip 22. The snap-fit ​​strip 22 is an arc-shaped strip, and the width at both ends of the snap-fit ​​strip 22 is smaller than the width at the middle of the snap-fit ​​strip 22. The snap-fit ​​strip 22 is horizontally positioned at the tail end of the threaded groove 21 near the barrel body 1. There is a distance between the end of the snap-fit ​​strip 22 near the tail end of the threaded groove 21 and the tail end of the threaded groove 21. The vertical intersection line of the snap-fit ​​strip 22 near the tail end of the threaded groove 21 is parallel to the vertical intersection line between the tail ends of the threaded groove 21 and the tail end of the threaded groove 21. The lid 2 is screwed onto the barrel opening ring 11 so that the snap-fit ​​strip 22 abuts against the barrel opening ring 11.

[0035] Reference Figure 1 and Figure 4 A sealing gasket 23 is adhered to the bottom wall of the inner cavity of the bucket lid 2. The sealing gasket 23 is made of TPE material. A sealing ring 24 is integrally formed on the end wall of the sealing gasket 23 near the bucket mouth ring 11. The sealing ring 24 protrudes from the sealing gasket 23.

[0036] The barrel opening ring 11 has an arc-shaped contact surface 13 at one end near the barrel lid 2, which abuts against both the sealing ring 24 and the sealing gasket 23. Under extreme conditions, the arc-shaped contact surface 13 can better adapt to the deformation between the barrel opening ring 11, the sealing ring 24, and the sealing gasket 23, ensuring a tight fit between the three and further reducing the risk of leakage.

[0037] The implementation principle of a high-sealing fluorinated container according to an embodiment of this application is as follows: After liquid is injected into the container, the container cap 2 is screwed onto the bottle neck ring. When the arc contact surface 13 of the bottle neck ring 11 abuts against the sealing ring 24 and the sealing gasket 23, the threaded section 12 completely slides into the threaded groove 21. At this time, the retaining strip 22 abuts against the top wall of the container body 1. The widened threaded section 12 and the chamfered corner 122 of the threaded section 12 with an increased tilt angle improve the sealing performance of the packaging container under extreme conditions.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
