Preferably, the shell 4 is integrally formed with a bottom 10 of the cup body 1, and a support portion 11 is formed below the bottom 10.

The working principle is as follows:

when paint is stored, the reservoir is upright and the seal 3 is closed as shown in figure 1. As shown in fig. 6 and 7, the protrusion 41 blocks the connection between the second connecting groove 323 and the vent groove 324, and outside air cannot enter the inside of the cup body through the vent hole 325. At the same time, paint does not leak down through the vent 325. If a small amount of paint flows into the second coupling groove 323 from the gap between the protrusion 41 and the second coupling groove 323, the space between the second coupling groove 323 and the first coupling groove 322 functions as a buffer to store the leaked paint, and the paint does not flow out of the case 4. Since the second connecting groove 323 is lower than the first through hole 321 when the reservoir is upright, paint is not easily introduced into the first through hole 321 upward through the first connecting groove 322.

During painting, the reservoir is inverted, the seal 3 is open, i.e. fig. 1 is rotated, the liquid passage 21 is below, the cup bottom 10 is above, and the liquid passage 21 is connected to the spray gun. The flange 33 is held by hand to pull the sealing member 3 outwards, so that the protrusion 41 no longer blocks the connection between the second connecting groove 323 and the vent groove 324. At the moment, the cup body 1 is ventilated with the outside. When the spray gun continuously sprays the paint in the cup body 1 outwards, the outside air can enter the cup body 1 through the vent 325 to balance the air pressure difference, and the cup body 1 is prevented from being broken due to the air pressure difference. As shown in fig. 8 and 9, air enters the inside of the cup body 1 from the outside through the vent hole 325, the first through hole 321, the first connecting groove 322 (first passage), the second connecting groove 323 (second passage), and the vent groove 324 (third passage) in this order. It should be noted that fig. 8 and 9 are illustrated in an upright state, and an upside-down state is assumed in actual painting.

If the paint is not used, the reservoir is placed on a flat surface (e.g. a table top), flange portion 33 first contacts the flat surface, then cup 1 is forced downwardly by gravity or by hand, and housing 4 moves downwardly relative to flange portion 33 until support portion 11 contacts the flat surface, at which time seal 3 is closed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not necessarily depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
