1. Field of Invention
The invention relates to cosmetic containers and more particularly to a cosmetic dispenser having a vibration device for massage.
2. Description of Related Art
A conventional cosmetic dispenser (e.g., deodorant or antiperspirant dispenser) is shown in
However, the well-known cosmetic dispenser suffers from several disadvantages. For example, it does not have a vibration device. Hence, no massage effect is produced. Moreover, it is not leak-proof. For example, preparation may spill out of the container 1 if it is held upside down or being squeezed due to inadvertence. Unfortunately, it is a tedious job to clean the leaked preparation. In addition, the volume of the dispensed preparation is not constant per application. It happens quite often that too much preparation is dispensed in a single application. This is a waste. Additionally, dirty liquid or the like may inadvertently flow into the container 1 to contaminate the preparation inside the container if preparation can be dispensed only by pressing the roller ball 4. Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a cosmetic dispenser comprising a cap, the cap comprises an internal space and an internally threaded section; a dispensing assembly disposed in the space of the cap and comprising a spring-biased plunger having a channel therethrough, and a dispensing seat releasably secured to the plunger; a case comprising an internal space with the dispensing assembly disposed therein, a communicating hole in communication with the space thereof, and an annular flange opposite the communicating hole; a container comprising an internal space for containing a quantity of preparation, and an externally threaded neck on a surface of a projecting open first end wherein the externally threaded neck is secured to the internally threaded section, and the flange is rested upon the externally threaded neck with the case being disposed in both the cap and the container; a battery barrel comprising an internal space and internal threads; a motor partially mounted in the space of the battery barrel; a switch comprising a push button exposed at one end of the battery barrel, the switch being mounted in the space of the battery barrel and being proximate to one end of the battery barrel; a conductor mounted in the space of the battery barrel and having both ends electrically connected to the switch and the motor respectively; a battery mounted in the space of the battery barrel between the switch and the motor, the battery mounted having positive and negative terminals electrically connected to the switch and the motor respectively; and a motor receptacle comprising an open first end releasably secured to the container, an open second end, and external threads on the second end, the external threads being threadedly engaged with the internal threads of the battery barrel to assemble the motor receptacle and the battery barrel together, and the motor being disposed in the motor receptacle; whereby in a preparation dispensing operation unfastening and removing the cap the plunger will axially move to clear the communicating hole so that the preparation flows from the space of the container to the dispensing seat through the communicating hole and the channel; whereby in a preparation stopping operation closing the cap onto the container and fastening same will cause the plunger to block the communicating hole; whereby in an on operation pressing the push button will electrically connect the battery, the motor, and the conductor together and activate the motor to cause vibration; and whereby in an off operation pressing the push button again will electrically disconnect the battery from the motor and deactivate the motor.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

The cap 10 has a closed upper end and an open lower end. The cap 10 comprises an internal space 11 and an internally threaded section 12 at its lower end. The dispensing assembly 20 comprises a hollow plunger 22 having a channel 21 therethrough, a dispensing seat 24 threadedly secured to the plunger 22, a plurality of (three) roller balls 26 rotatably retained at a plurality of (three) holes (not numbered) of the dispensing seat 24 respectively, and a helical spring 23 put on the plunger 22. The case 30 is cylindrical and has a closed lower end and an open upper end. The case 30 comprises an internal space 33, a communicating hole 31 at the lower end in communicating with the space 33 and the exterior, and an annular flange 32 at the upper end. The lower end of the plunger 22 is fastened at the bottom of the case 30 and the spring 23 is disposed and biased in a space defined between the case 30 and the plunger 22 when the plunger 22 is disposed in the case 30.
The container 40 comprises an internal space 41 for containing a quantity of preparation, an externally threaded neck 42 on a surface of a projecting open upper end, and an annular groove 431 on a surface of a projecting closed lower end. The externally threaded neck 42 is secured to the internally threaded section 12, and the flange 32 is rested upon the upper end of the externally threaded neck 42 with the dispensing assembly 20 and the case 30 being assembled in the space 11 and an upper portion of the container 40 when the cap 10 is closed onto the container 40.
For flowing the preparation from the space 41 to the channel 21 in a preparation dispensing operation, a user can unfasten and remove the cap 10. The compressed spring 23 thus automatically expands to push the plunger 22 upward. As such, the communicating hole 31 is not blocked by the plunger 22. The user then may rotate the roller balls 26. As a result, the preparation flows from the space 41 to the exterior through the communicating hole 31, the channel 21, and the surfaces of the rotating roller balls 26 (see
To the contrary, for stopping the flow of the preparation from the space 41 to the channel 21, the user can close the cap 10 onto the container 40 and fasten same by threading. The communicating hole 31 is thus blocked by the downwardly moved plunger 22 with the spring 23 being compressed (see
The battery barrel 50 is hollow and comprises an internal space 51, internal threads 52, and a hole (not numbered) at a lower end. The motor 60 is mounted in the space 51. The switch 70 is a conventional electronic push button switch and has a positive terminal and a negative terminal The switch 70 comprises a push button 71 projecting through the hole of the battery barrel 50 to be exposed. The switch 70 is also mounted in the space 51 and is proximate to the lower end of the battery barrel 50. The conductor 80 is also mounted in the space 51 and has both ends electrically connected to the switch 70 and the motor 60 respectively.
The battery 90 is also mounted in the space 51. The battery 90 is disposed between the switch 70 and the motor 60 and has both terminals (i.e., positive and negative terminals) electrically connected to the switch 70 and the motor 60 respectively. The motor receptacle 100 is a hollow cylinder and comprises an open upper end 101, an internal annular ridge 1011 proximate to the upper end 101, the ridge 1011 being matingly engaged with the groove 431 to assemble the motor receptacle 100 and the container 40 together, an open lower end 102, and external threads (not numbered) on the lower end 102, the external threads being threadedly engaged with the internal threads 52 to assemble the motor receptacle 100 and the battery barrel 50 together. The motor 60 is mounted in the motor receptacle 100 and comprises a driving shaft 62 and a cam member 61 mounted on an open end of the driving shaft 62, the cam member 61 being proximate to the bottom of the container 40.
The cosmetic dispenser operates as follows. A user can press the push button 71 one time (i.e., the switch 70 is in an on position) to electrically connect the battery 90, the motor 60, and the conductor 80 together. Hence, the motor 60 is activated to continuously rotate the cam member 61 via the driving shaft 62. As a result, a vibration (i.e., massage) effect is produced at a lower portion of the cosmetic dispenser (see

The invention has the following advantages. In addition to typical preparation dispensing function, it has vibration (i.e., massage) function. Thus, the cosmetic effect is more significant. Further, the volume of dispensed preparation is precisely controlled by a valve comprising the communicating hole 31 and the plunger 22. Furthermore, no preparation leakage is possible.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
