Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a nib attached to the front end of a barrel for powdering powder for cosmetics, writing instruments, etc., having an appropriate particle size, which is housed in the barrel. The present invention relates to a powder supply tool capable of supplying an appropriate amount.

(Prior Art) Liquids of various viscous types are stored in a barrel, and liquids can be directly supplied to a pen tip attached to the front end of the barrel by roughly classifying a liquid supply tool. It is divided into a pressure type that pressurizes with air or air and forcibly supplies it to the pen point, and a natural derivation type that draws liquid to the pen point using a capillary action via a so-called bellows or relay core. The former pressurization formula is effective when the viscosity of the liquid is high, and the latter naturally derived formula is effective when the viscosity of the liquid is low.

(Problems to be Solved by the Invention) However, it is difficult to supply an appropriate amount of powder having any particle diameter to the pen tip with the above-mentioned pressure type or naturally derived type. Therefore, even if the powder can be supplied, it is limited to the case where the powder used has physical properties similar to those of a liquid.

Therefore, the present invention aims to provide a powder supply tool that can reliably supply powder for cosmetics, writing, etc., having an appropriate particle size, to the nib and that the supply operation is simple.

(Means for Solving the Problem) According to the present invention, a pen tip attached to a front end portion of a shaft cylinder faces a front end opening portion of a storage pipe for storing powder, and a continuous inclined surface is formed in the storage pipe. Insert a spiral body that has a spiral shape,
Here, the front end portion of the spiral body is rotatably fitted and inserted into the front end opening portion of the storage tube, and the rear portion of the spiral body is rotatably fitted to the rear portion of the storage tube. The portion is fixed to a rotor having a rear portion, and when the rotor is rotated in this way, the spiral body is also rotated.Furthermore, by a biasing operation by a spring to push the knob projected from the rear end of the barrel, A rotor that slides while rotating at a predetermined angle in conjunction with the sliding of a slider that is connected to a knob allows the slidability of the rotor with respect to the rotor in the engaging portion of the rotor. However, the rotating body is rotated by an operation of pressing a knob protruding from the rear end of the barrel, which is engaged with the rotating body and the rotor so as to rotate integrally, against the backward biasing force of the spring. And the powder is supplied to the pen tip by rotating the spiral in conjunction with the rotation of the rotor. And gist Unishi was powder supply device.

(Examples) Hereinafter, the present invention will be described in detail based on Examples.

In FIGS. 1 and 2, reference numeral 1 is a pen tip whose base portion 1a is attached to a front end portion 2a of a barrel 2 and which is capable of containing and applying powder. Although a brush-like object in which synthetic fibers are bundled is shown, a porous elastic body such as a sponge or a synthetic rubber appropriately cut may be used. Reference numeral 3 is a storage tube for storing powders for cosmetics, writing, etc. having an appropriate particle size. The storage tube 3 is fixedly arranged in the barrel 1 and the front end opening 3a thereof is provided in the pen tip 1
It is located at the insertion position in the base portion 1a. Reference numeral 4 denotes a rotor that is rotatably fitted to the rear portion of the storage tube 3, and the rotor 4 has an engaging portion 4a having a non-circular cross section at the rear portion. Reference numeral 5 denotes a spiral body formed by spirally forming a continuous inclined surface 5a by twisting a thin metal plate a plurality of times, and the spiral body 5 inserted into the storage tube 3 has a front end portion at the front end of the storage tube 3. It is rotatably fitted in the opening 3a, and the rear end is fitted and fixed in the recess 4b of the rotor 4, so that the rotor 4 can be rotated to rotate in the storage tube 4. On the other hand, the knob 6 protruding from the rear end of the barrel 2
A plurality of projections 7b each having a sloped surface 7a inclined in one direction at the front end are provided on the outer peripheral surface as many as longitudinal grooves 8 to be described later, and the projections 7b are formed on the inner surface of the rear portion of the barrel 2 at equal intervals. A slider 7 that can be slidably fitted in is continuously provided. Reference numeral 9 denotes a rotating body which is rotatably arranged in front of the slider 7.
Is a projection 9b having a slope 9a inclined in the same direction as the slope 7a.
And a spring 10 stretched between the shaft tube 2 and
Is urged rearward by pressing the projection 9b into a recess 8c composed of a sloped surface 8a and a vertical surface 8b inclined in the same direction as the sloped surface 9a formed at the same pitch as the vertical groove 8 at the front end of the vertical groove 8. positioned. Further, the rotating body 9 has an inner diameter that is slidably and non-rotatably engaged with the engaging portion 4a of the rotor 4.
For example, as shown in FIG. 3, when the engaging portion 4b of the rotor 4 has a rectangular cross section, the inner diameter may be the same as the engaging portion 4b and slightly larger. Reference numeral 11 denotes a sealing member made of an elastic material such as a sponge fitted in the rear portion of the storage tube 3 in order to prevent the powder contained in the storage tube 3 from leaking out.

Next, the operation of the above-described embodiment will be described.

When the knob 6 projecting from the rear end of the shaft cylinder 2 is pressed forward with a fingertip, the protrusion 7b of the slider 7 advances along the vertical groove 8, and the slope 7a at the front end is changed to the slope of the protrusion 9b of the rotating body 9. After contacting 9a,
In this state, the protrusion 9b is pressed forward to move the rotating body 9 forward. Since the rotating body 9 is biased rearward by the spring 10 and is pressed against the slope 9a by the slope 7a of the protrusion 7b, the protrusion 9b slightly rotates past the front end of the vertical surface 8b of the recess 8c and is adjacent to the protrusion 9b. It goes into the slope 8a of the recess 8c. Then, when the pressing of the knob 6 is released, the protrusion 9b slides while rotating along the inclined surface 8a and comes into contact with the vertical surface 8b and stops. In this way, by pressing the knob 6, the rotating body 9 can be rotated by an angle according to the pitch of the concave portions 8c.
The rotor 4 engaged with the rotor 4 also rotates by the same amount, so that the inclined surface 5a of the spiral body 5 that rotates integrally with the rotor 4 guides the powder stored in the storage pipe 3 to the front in order. 3 can be supplied into the nib 1 through the front end opening 3a. In this powder supply operation, if the pen tip 1 is tilted slightly downward, the powder stored in the storage tube 3 can be moved forward by its own weight. Can be fed into the destination 1.

The spiral body 5 described above is not limited to the one shown in the figure, and a spiral blade attached to the peripheral surface of the core rod may be adopted.
The spiral inclined surface 5a does not need to be formed so as to extend over the entire storage tube 3, but it is useful as long as it is formed corresponding to at least the front end opening 3a of the storage tube 3. Alternatively, the powder can be supplied into the pen tip 1 even if the front end opening 3a of the storage tube 3 is opposed to the pen tip 1 without being inserted into the base portion 1a of the pen tip 1. In addition, various modifications can be made without departing from the scope of the present invention.

(Effects of the Invention) As described above, according to the present invention, by pressing the knob projecting from the rear end of the barrel, the spiral body is rotated by a predetermined angle with respect to the storage tube in which the powder is stored, and the rotation is performed. A suitable amount of powder can be guided forward by the spiral inclined surface of the spiral body and supplied to the pen tip, so the desired amount of powder can be reliably delivered to the pen tip by a simple operation of pressing the knob. Can be supplied.
