[0008] In one embodiment, the circumferential angle of the external thread segment around the cup body is no greater than 120 degrees.

[0009] In one embodiment, a plurality of hollow openings are provided on the annular flange, and the hollow openings are arranged above the corresponding sub-thread segments.

[0010] In one embodiment, the lower surface of the inner circle of the hollow opening is an inclined surface, and the inclined surface is flush with the upper surface of the sub-thread segment.

[0011] In one embodiment, the length of the inclined surface of the hollow opening is not less than the length of the upper surface of the sub-thread segment.

[0012] In one embodiment, a filter screen is provided on the inner wall of the cup cover, and the filter screen covers the inner pipe opening of the connecting pipe.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] like Figure 1-Figure 5 As shown, the present application provides a spray container, including a cup body 1 and a cup cover 2.

[0026] The outer wall of the cup body 1 is provided with a plurality of external thread segments 101, which are sequentially arranged along the outer peripheral wall of the cup body; an insertion opening is formed between adjacent ends of two adjacent external thread segments 101; and the plurality of external thread segments 101 form the first locking portion 110;

[0027] The cup cover 2 is provided with a connecting tube 21. The edge of the cup cover 2 is provided with an annular flange 201. The inner wall of the annular flange 201 is provided with multiple internal thread segments 202. The multiple internal thread segments 202 are arranged in sequence along the inner circumferential wall of the annular flange 201. The multiple internal thread segments 202 form the second locking portion 20.

[0028] The internal thread segment 202 is connected to the corresponding external thread segment 101 , and the cup cover seals the cup opening of the cup body.

[0029] In addition, the internal thread segment 202 includes a plurality of sub-thread segments 2021 , and the plurality of sub-thread segments 2021 of the same internal thread segment 202 are sequentially arranged at intervals along the corresponding external thread segment 101 .

[0030] Specifically, the edge of the cup lid 2 is formed into an annular flange 201, and a plurality of internal thread segments 202 are formed on the inner wall of the annular flange 201. Correspondingly, a plurality of external thread segments 101 are provided on the outer wall of the cup body near the cup opening. When the cup lid 2 is assembled onto the cup body 11, the internal thread segments 202 at corresponding positions are inserted under the corresponding external thread segments 101 through the insertion openings formed between the adjacent ends of the external thread segments 101. After the cup lid 2 is tightened, the cup lid 2 is fastened to the cup body 11 and seals the cup opening of the cup body 11.

[0031] To facilitate the processing of the cup lid 2 and improve the connection reliability between the internal thread segment 202 and the external thread segment 101, the internal thread segment 202 is composed of multiple sub-thread segments 2021. Moreover, the multiple sub-thread segments 2021 within the same internal thread segment 202 are distributed along the extension curve of the corresponding external thread segment 101. In this way, during connection, the multiple sub-thread segments 2021 within the same internal thread segment 202 can be more closely attached to the surface of the corresponding external thread segment 101, thereby improving the connection reliability.

[0032] Since the same internal thread segment 202 is designed in sections, multiple shorter sub-thread segments 2021 can be machined on the inner surface of the annular flange 201, effectively reducing machining difficulty and facilitating mold removal, thereby avoiding the difficulty of molding mold removal caused by machining longer thread segments on the inner surface of the annular flange 201. At the same time, the same external thread segment 101 cooperates with multiple sub-thread segments 2021 to ensure a reliable connection between the cup lid 2 and the cup body 11, thereby improving the reliability of the connection.

[0033] The circumferential angle of the external thread segment 101 around the cup body 1 is no more than 120 degrees, so as to shorten the overall length of the external thread segment 101 of the cup body 1 .

[0034] Furthermore, a plurality of hollow openings 203 are provided on the annular flange 201 , and the hollow openings 203 are arranged above the corresponding sub-thread segments 2021 .

[0035] Specifically, by providing a hollow opening 203 on the annular flange 201, the hollow opening 203 matches the corresponding sub-thread segment 2021. In this way, when demolding, the part where the sub-thread segment 2021 is formed in the mold can be separated from the cup cover 2 through the hollow opening 203 to reduce the difficulty of demolding.

[0036] The lower surface of the inner circle of the hollow opening 203 is an inclined surface 2031 , and the inclined surface 2031 is flush with the upper surface of the sub-thread segment 2021 .

[0037] Specifically, in order to improve the processing accuracy of the sub-thread segment 2021, the lower surface of the hollow opening 203 can be designed as an inclined surface 2031. The inclined surface 2031 is used to meet the requirement of the inclined extension arrangement of the sub-thread segment 2021. The length of the inclined surface 2031 of the hollow opening 203 is not less than the length of the upper surface of the sub-thread segment 2021.

[0038] In another embodiment, a ventilation hole 102 is provided at the bottom of the cup body.

[0039] Specifically, for a spray container without an inner liner, the cup body 11 is directly filled with paint. During use, in order to ensure air pressure balance, an air vent 102 may be provided on the cup body 11. The air vent 102 may be blocked with a plug during the paint filling process to prevent leakage; during the painting process, the plug is opened to open the air vent 102 to allow air to enter.

[0040] Furthermore, an elastic member 103 is provided on the outer cup, and the elastic member 103 spans over the vent hole 102 . A blocking member 104 is also provided on the elastic member 103 , and the blocking member 104 is configured to be selectively inserted into the vent hole 102 .

[0041] Since the bottom of the outer cup 11 is integrally formed with the elastic member 103, the elastic member 103 spans the vent hole 102, and the elasticity of the elastic member 103 is used to press the blocking member 104 against the vent hole 102. At the same time, after the vent hole 102 is opened, the blocking member 104 on the elastic member 103 will not fall off, making it convenient to use.

[0042] Furthermore, in order to filter impurities in the paint, a filter screen (not shown) can be provided on the inner wall of the pot cover, and the filter screen covers the inner pipe opening of the connecting pipe.

[0043] Specifically, the filter screen can filter the paint flowing toward the connecting pipe to remove impurities in the paint. To facilitate the installation of the filter screen, a mesh frame is provided on the outer periphery of the filter screen. The inner wall of the lid is provided with a plurality of raised claws 204 around the connecting pipe, and the mesh frame of the filter screen is clamped between the plurality of these claws.

[0044] In another embodiment of the present application, at least one connecting portion is provided on the outer tube wall of the connecting tube 21. The connecting portion includes two ribs 211 arranged side by side. A slot 223 is formed between the two ribs 211. The slot 223 extends along the outer circumference of the connecting tube 21.

[0045] The cup cover 2 is arranged on the cup body 1, and the slot is configured to form an insertion space.

[0046] Specifically, a corresponding connecting portion of an integrated structure is formed on the connecting tube 21 on the cup cover 2 , and the connecting portion is composed of two ribs 211 , and a slot is formed between the two ribs 211 to meet installation requirements.

[0047] During use, a corresponding plug-in portion (spiral wedge-shaped element) is formed on the external component for fixing the cup cover 2, so that the plug-in portion is inserted between the two ribs, and the plug-in portion is clamped between the two ribs 211 to complete the assembly.

[0048] Since the plug-in part is clamped between the two ribs 211, during use, the shaking of the plug-in part will alternately apply external force to the two ribs 211. The two ribs 211 are used to withstand the impact force generated by the plug-in part during use, reducing damage to the ribs 211 and improving reliability.

[0049] The connecting tube 21 may be configured with only two ribs 211 to withstand the impact force generated by the plug-in portion during use. The width of the slot 223 formed between the two ribs 211 may be a gradual structure. That is, as the spiral wedge-shaped element is inserted into the slot 223, the width of the slot 223 gradually decreases, thereby firmly locking the spiral wedge element in place and preventing it from rotating excessively and falling out of the slot 223.
