(2) According to the valve structure according to the present invention, a commercially available product can be removed from the container by improving the fluidity of the filled liquid due to the minus pressure due to temperature fluctuations or the temperature of the warehouse being too high. Leakage can be prevented.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 to FIG. 3 will be referred to. The valve structure according to the present invention includes a bush 10, a piston rod 20, a nozzle 30, a sleeve 40, and a brush 50.

The bush 10 is provided with an accommodation space 11 opened at one end in the axial direction at one end, and a stepped contact surface 111 is formed on the inner surface thereof, and an outlet is provided at an appropriate place on the outer surface of the other end. 12 is open and a film 121 is provided at an appropriate location of the outlet 12.

The piston rod 20 is provided with an annular projection 21 at an appropriate location on the outer surface, and the annular projection 21 is formed at one end with a rod portion 22 that fits the bottom end of the inner surface of the receiving space 11. An engaging portion 23 is formed on the outer surface of the other end, and a communication hole 24 through which the nozzle 30 is inserted is provided in the middle of the piston rod 20 in the axial direction.

The nozzle 30 is hollow, and is provided at one end with a communication portion 31 that fits into the bottom end of the inner surface of the communication hole 24 of the piston rod 20, and at a suitable location on the outer surface of the nozzle 30. 32 is recessed to form an outflow nozzle 33, and the outflow nozzle 33 is provided with a plurality of outflow holes 311. In this embodiment, four outflow holes 311 are provided.

The sleeve 40 is hollow, and at one end is provided with a fitting portion 41 that fits on the outer surface of the engaging portion 23 and abuts against the annular protrusion 21, and a fitting opening 42 opens in the axial direction at the other end. An annular groove 43 that fits to the outer surface of the bush 10 is formed at an appropriate location on the outer surface of the sleeve 40, and the fitting portion 41 has an annular groove 43 and a contact surface 111. An elastic element 44 that is in contact with the elastic member 44 is fitted.

One end of the brush 50 is provided with a bundling sleeve hole 51 that is inserted into the fitting opening 42, is in contact with the joining edge 32, communicates with the outflow nozzle 33, and is located in the communication hole 24. It can be a lipstick head or a brush with different dimensions.

The use state of the present invention will be described in detail with reference to FIG. When the sleeve 40 receives an external force, the annular groove 43 of the sleeve 40 pushes the elastic element 44 against the contact surface 111, the fitting portion 41 of the sleeve 40 pushes the annular protrusion 21, and the rod portion 22 of the piston rod 20 is accommodated. The outlet 12 is pushed to the bottom end of the space 11 to close the outlet 12. At this time, the outlet 12 is in a closed state, so that the liquid in the container cannot flow out, and the sleeve 40 is elastic when receiving no external force. The element 44 moves the sleeve 40 in the axial direction, and the rod portion 22 of the piston rod 20 moves away from the outlet 12. At this time, the outlet 12 is opened, and the outlet 12 and the bundled sleeve hole 51 are formed. As a result, the liquid can flow out of the brush 50 uniformly, and the convenience of use is extremely high, and the film 121 is installed at an appropriate location of the outlet 12. Therefore, when the liquid container 13 is used, the pressure of the liquid opens the film 121, and when the liquid container 13 is not used, the film 121 automatically returns to the closed state, and the sealing performance is extremely good. According to the valve structure according to the present invention, a commercially available product leaks from the container due to the fluidity of the filled liquid being improved due to the minus pressure due to temperature fluctuations or the temperature of the warehouse being too high. Can be prevented.

  However, the valve structure can be attached together with the nozzle 30 to the liquid container 13 having a larger size or the brush 50 having a larger size, so that the liquid can flow out uniformly.

Therefore, the valve structure of the second embodiment according to the present invention may be attached to a brush 92 having a smaller size and a smaller size as shown in FIGS. The valve structure according to the second embodiment of the present invention includes a bush 60, a piston rod 70, a sleeve 80, and a pen tube 90.

The bush 60 is provided with an accommodation space 61 opened at one end in the axial direction at one end, and a stepped contact surface 62 is formed on the inner surface of the accommodation space 61. Then, the outflow port 63 is provided open, and is provided by being fitted to the end edge of the liquid container 64 at the contact portion 65 at the end edge of the accommodating space 61 of the bush 60.

The piston rod 70 is hollow, and a convex portion 71 is provided at a predetermined position inside, and an annular protrusion 72 is provided at one end at an appropriate position on the outer surface in a diametrical direction, and is engaged. A rod 74 having a smaller diameter extends at the other end, and the rod 74 is fitted in the elastic element 75 and installed in the accommodating space 61 so that one end of the elastic element 75 is a bush. 60 abuts against the abutment surface 62 of

The sleeve 80 is hollow and is provided with a fitting portion 81 at one end. A contact surface 82 for fitting the engaging portion 73 on the piston rod 70 is formed on the inner surface of the fitting portion 81. A conical body 83 is formed at the other end of the sleeve 80.

The pen tube 90 is provided with an annular groove 91 on the outer surface of one end thereof. The annular groove 91 of the pen tube 90 fitted with the sleeve 80 is engaged with the convex portion 71 of the piston rod 70, and the other end is provided with the other end. A brush 92 is fitted.

With the above configuration, when the annular protrusion 72 of the piston rod 70 receives an external force, the rod 74 of the piston rod 70 compresses the elastic element 75, and the bottom end of the rod 74 abuts against the bottom surface of the accommodation space 61. When the rod 74 blocks the outlet 63, the outlet 63 is closed, so that the liquid in the container cannot flow out, and when the annular protrusion 72 of the piston rod 70 is not subjected to external force, The elastic element 75 moves the piston rod 70 in the axial direction, and the rod 74 is separated from the outlet 63. At this time, the outlet 63 is opened, and the outlet 63 and the brush 92 are in communication. The operation of the piston rod 70 and the elastic element 75 allows the liquid to flow out of the brush 92 uniformly.

Therefore, since the valve structure according to the present embodiment can be attached to the liquid containers 13 having different dimensions or the brushes having different dimensions, the convenience of use is extremely high.
