Description

Technical Field

[0001] The utility model belongs to the technical field of packaging barrels, and in particular relates to a multifunctional gas end cover for an electronic-grade packaging barrel. Background Art

[0002] With the rapid development of China's microelectronics industry, the rise of the semiconductor industry, and the continuous improvement of the localization rate, the demand for wet electronic chemicals has shown a rapid growth trend. The rapid growth in the demand for wet electronic chemicals has led to the continuous expansion of the market demand for electronic-grade packaging barrels. Electronic-grade packaging barrels are made in the form of blow molding. During the cooling and shaping process and subsequent use, the gas-setting cover needs to be replaced. The opening of the gas-setting cover is often large. When replacing it, the opening often increases the risk of contamination, reduces the cleanliness of the barrel, seriously affects the use of electronic-grade packaging barrels, and causes economic losses. Therefore, improving the design of the gas-setting cover and reducing the frequency of replacement of the gas-setting cover during use can greatly reduce the risk of contamination. Summary of the invention

[0003] In view of the above technical problems, the utility model provides a multifunctional air end cap for an electronic-grade packaging barrel, which can effectively reduce the frequency of replacing the air-setting cap during the use of the electronic-grade packaging barrel, greatly reduce the risk of contamination, and improve the cleanliness of the packaging barrel.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a multifunctional gas end cover for an electronic-grade packaging barrel, wherein an inner plug is provided with an inner plug O-ring outside the inner plug, the inner plug O-ring seal is covered with a setting cover, and the setting cover is provided with a first O-ring, a second O-ring and a third O-ring outside the setting cover.

[0005] Preferably, the top of the inner plug is provided with an inner hexagonal countersunk hole, and the outside is provided with an inner plug external thread.

[0006] Further preferably, the inner plug is a breathable cover inner plug or a gas end cover inner plug.

[0007] More preferably, a breathable membrane is provided at the bottom of the inner plug of the breathable cover, and inner plug breathable holes are provided inside.

[0008] Preferably, the top of the shaping cover is provided with a shaping cover top fan-shaped groove, and the side is provided with a first O-ring groove, a second O-ring groove and a third O-ring groove in sequence; the inside is provided with a shaping cover internal thread, a shaping cover external thread and a shaping cover air vent.

[0009] Further preferably, the first O-ring groove cooperates with the first O-ring, the second O-ring groove cooperates with the second O-ring, and the third O-ring groove cooperates with the third O-ring.

[0010] Further preferably, a breathable membrane base is also provided inside the shaping cover.

[0011] Preferably, the shaping cover and the inner plug are made of HDPE, UMPE, PFA, or PVDF.

[0012] Preferably, the O-ring is made of LDPE, POE, EPDM, FKM, or FKKM.

[0013] Preferably, the breathable membrane is made of PTFE, PVDF, PP, or UPE.

[0014] The beneficial effects of the present invention are:

[0015] 1. A vent hole with a lateral opening is provided at the bottom of the shaping cover, which is beneficial to shaping the packaging barrel during production and ventilation during use. While ensuring the balance of internal and external air pressure during production, it reduces external environmental pollution from entering the interior and improves the cleanliness of the packaged product.

[0016] 2. There are three O-ring grooves on the external thread of the shaped cover, which are sealed with O-rings to seal the packaging barrel, ensuring that chemicals will not leak from the barrel mouth during transportation and storage, eliminating safety risks and reducing chemical pollution.

[0017] 3. Equipped with an inner plug, after the packaging barrel is cooled and shaped, there is no need to remove the gas-setting cover. The packaging barrel can be directly sealed by screwing in the inner plug to store electronic-grade chemicals, reducing the risk of pollution caused by replacing the gas-setting cover.

[0018] 4. There are two types of inner plugs. One is a breathable cap inner plug with inner plug ventilation holes and breathable membrane, which is suitable for storing electronic-grade chemicals that need to have ventilation function. The other is an inner plug without ventilation holes, which is stored as a blind cover and can be used as a gas-shaped cover for shipment. The choice of the two inner plugs constitutes a gas end cap with multiple optional functions. BRIEF DESCRIPTION OF THE DRAWINGS
