Description

Rotary Rod Dispensing Mechanism

The present invention relates to a rotary rod dispensing mechanism for dispensing rod-like cosmetics, rod erasers, colored pencils, etc., which are applied to a lip balm, an eye pencil, an eyeliner, and the like by a rotating operation.

In the conventional rotary rod dispensing mechanism, for example, the rod-shaped dispensing mechanism shown in Fig. 16 has been proposed, and the writing instrument is a spiral wire 13 attached to the front end of the rotary manipulator 12 and the wire. The mechanism which consists of the holder 14 attached in (13) is comprised by the structure which rotated and fitted in the outer cylinder 1 freely. In addition, the code | symbol 15 in a figure is a front cover screwed to the spiral groove 11a formed in the inner peripheral surface of the front end part of the outer cylinder 11. As shown in FIG.

In the conventional rod-shaped article dispensing mechanism, when the rotary operation unit 12 is rotated in one direction, the spiral wire 13 also rotates together to stop the rotation of the holder 14 fitted to the spiral wire 13. Since the projection 14a is coupled to the guide groove 11b formed in the axial direction on the inner wall of the outer cylinder 11, the holder 14 is prevented from rotating.

On the other hand, since the holder 14 has three joiners 14b and is fitted to the spiral wire 13 by these, the holder 14 moves axially along the spiral wire 13, and as a result, The rod-shaped object attached to the front end of the holder 14 is gradually drawn out from the opening of the front end of the front cover 15 of the outer cylinder 11. In addition, when the rotary operation part 12 is rotated in the opposite direction to the above, the rod-shaped object moves in the retraction direction.

However, the conventional rotary rod dispensing mechanism as described above is structurally unreliable in drawing up the rod, and cannot be exchanged with a new one unless a finger tip is directly applied to the rod after consumption of the rod. The fingertips are soiled by these rods, and when the rods are cosmetics such as lip balms, the fingertips touch and bacteria adhere to the rods.

In addition, the conventional example has a large number of parts and a large amount of shaking due to the clearance between the parts, so that the rod-shaped object stored in case of accidental drop is broken, and beyond the rotation operation necessary for the slider moving range. If the operation is continued, parts may be damaged due to excessive rotation operation.

The present invention is to solve the conventional problems as described above, the rod-shaped material holding portion as a cassette-type structure, when replacing the rod-like objects such as cosmetics can be exchanged without touching the rod directly. Accordingly, when the finger tip is contaminated and the rod-like object such as cosmetics does not adhere to the microscopic microorganisms on the cosmetics by the finger-tip, it is an object of the present invention to provide a rotating rod-feeding mechanism that is good for hygiene.

In addition, although the present invention has such a cassette-type function, the number of parts is reduced, the assembly is facilitated, and the coupling tolerance between parts is reduced, thereby eliminating damage to the rods by falling, and exceeding the operating limit. It is an object of the present invention to provide a rotary rod-shaped article dispensing mechanism having good feeding operation in which parts are not damaged even by excessive rotational operation.

In addition, the present invention forms a cassette-shaped linear shaft shorter than the rear shaft to improve operability, and at the same time, does not protrude the central shaft as much as possible from the rear end of the linear shaft. It is an object of the present invention to provide a rod-shaped article dispensing mechanism which is prevented from feeding the rod-shaped article.

In order to achieve the above object, the present invention is a linear shaft with a spiral groove formed on the inner circumference, and a rear shaft formed to be detachable and rotatable at the same time as the rear portion of the shaft is located inside, and detachable at the same time and the rear shaft A slider formed at a rear end thereof with a coupling means for preventing rotation by mutual coupling with a coupling means formed therein, and a slider formed to be movable in the longitudinal direction in accordance with the rotation of the linear shaft while retaining the rod-shaped object in the middle axis; It consists of a rotary rod-shaped object dispensing mechanism which is composed of (slider).

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

Fig. 1 shows a rotary rod-feeding mechanism for feeding rod-like cosmetics such as ibrosim, and has a linear shaft 1 having an opening 1a through which the rod-shaped article is fed out, and a rotation about the shaft 1 It consists of the rear shaft 2 provided so that it may be formed in the shape of a pencil as a whole.

As shown in FIG. 2, the front part of the linear shaft 1 is formed gradually decreasing in diameter toward the opening 1a, and the stopper part 1b inclined inwardly spaced apart from the opening 1a is formed. Further, an annular projection 1d is formed on the inner circumference of the rear end of the linear shaft 1 as a fitting means, and the spiral groove 1c of a line, which is spaced apart from the annular projection 1d and serves as a guide spiral means, faces forward. On the other hand, the spiral grooves 1c may be formed beyond the double line as necessary.

The ridge portion 1f is formed at a front position spaced apart from the annular projection 1d of the linear shaft 1, and the ridge portion 1f has an annular groove 1e in which an O-ring 5 to be described later is mounted. On the other hand, a fitting recess 1g is formed on the inner circumference of the rear linear shaft 1 spaced apart from the annular projection 1d on the other side as a fitting means.

In addition, the rear shaft 2, the rear portion of the linear shaft 1 is fitted, as shown in Figure 3, the front portion of the rear shaft 2 is formed in a small diameter portion (2a) of thin thickness, the inner circumferential projection ( An annular recess 2b is formed as a fitting means fitted with 1d). In addition, six coupling ribs 2c are formed inside the front part of the rear shaft 2 toward the front, and the front ends of the coupling ribs 2c are formed with projections 2cc, as shown in Fig. 9. The six coupling ribs 2c are formed at equal intervals, and it is better to be as thin as possible from the technical point of view that will be described later if the strength is acceptable.

In addition, the rear end of the rotatable middle shaft 3 together with the rear shaft 2 is formed to be coupled to the inside of the front portion of the rear shaft (2). That is, the middle shaft 3 has a pair of guide slits 3a (slit) facing each other in the longitudinal direction in the front of the middle shaft 3, as shown in FIG. 4, and one side of the guide slits 3a. A width-expansion portion 3aa is formed in the front part in consideration of the assembly work, and a step portion 3b is formed at the rear of the slit 3a, and the surface treatment is carried out at the middle shaft head portion 3d forming the step portion 3b. As the fitted fitting means, a plurality of fitting protrusions 3c are formed.

Further, the annular projection 3e having the largest diameter is spaced apart from the fitting projection 3c and is formed on the outer circumference, and is connected to the annular projection 3e, and four coupling ribs 3f are integrally formed in the longitudinal direction. At the rear end thereof, protrusions 3ff are formed to guide the coupling ribs 2c of the rear shaft 2 toward the rear, respectively, and as shown in FIG. 9, the coupling ribs 3ff are equally spaced at four intervals. If a bone is formed and is acceptable in terms of strength, it is better to be as thin as possible from a technical point of view.

That is, since the proper angle of the guiding protrusion 3ff is almost constant, the width of the coupling rib 3f becomes long as it is wide. Therefore, when the intermediate shaft 3 is installed in the linear shaft 1, the protrusion 3ff of the coupling rib 3f will protrude to a wide extent from the rear end of the linear shaft, and the user excessively rotates this portion to form a rod-like object. The configuration of the above form is necessary so that there is no Buddha-like accident that helps to dissipate.

Moreover, in the said intermediate shaft 3, the slider 4 of the form shown to FIG. 6 thru | or 8 is provided so that the inside of the slit 3a may slide. In detail, the front of the slider 4 has a pair of divided grooves 4a formed therebetween, and a thin skin-like rod-shaped material holding portion 4b is provided between the divided grooves 4a. Inside the front end of this rod-shaped holding portion 4b, a small projection is formed so that the rod-shaped article is easy to be mounted and its holding force is sufficiently obtained.

In addition, the engaging portion 4c for the guide is formed at the rear of the rod-shaped object holding portion 4b, and in one engaging portion 4c, the spiral groove 1c of the middle shaft 3 is higher than this. The engaging projection 4cc formed by engaging with the inclination is formed integrally, where the slider 4 is installed on the middle shaft 3, and the engaging portion 4c is engaged in the slit 3a of the middle shaft 3, The slider 4 is operated up and down. In addition, the engaging projection 4cc is engaged with the spiral groove 1c formed on the inner circumference of the linear shaft 1 to guide the slider 4.

In addition, the relationship between the rear shaft 2 and the middle shaft 3 will be described. In the inner side of the rear shaft 2, the coupling rib 2c formed in the longitudinal direction and the outer end of the rear end of the middle shaft 3 in the longitudinal direction. By engagement with the formed coupling ribs 3f, the middle shaft 3 is configured to be incapable of rotational movement with respect to the rear shaft 2. That is, the coupling ribs 2c and 3f are formed to face the projection protrusions 2cc and 3ff, respectively.

Therefore, when assembling, each of the coupling ribs 2c and 3f is positioned on the same line, and both are guided to the protrusions 2cc and 3ff so that they are assembled in consideration of the orientation. In addition, through the above description, it is preferable that the projection 3ff of the middle shaft 3 protrudes from the rear end of the linear shaft as much as possible, and the coupling rib 3f is thinned in a range where strength is allowed.

In the drawing, reference numeral 5 is an O-ring made of an elastic material such as rubber, and is provided in the annular groove 1e of the linear shaft 1, so that the linear shaft 1 and the rear shaft 2 can be easily assembled. In addition to smoothing the mutual rotation.

As understood by the configuration of the rotary rod-shaped article dispensing mechanism according to the embodiment, the assembly sequence is as follows. That is, first, the slider 4 is inserted into the middle shaft 3 to the slit 3a. After the coupling, the installed intermediate shaft 3 and the slider 4 are rotated and fitted into the linear shaft 1, and the slider 4 is fitted into the spiral groove 1c inside the linear shaft 1 so that the intermediate shaft 3 is fitted. It is completely press-fitted and engaged by the coupling structure to be rotated together.

Further, the O-ring 5 is assembled to the linear shaft 1, covered with the intermediate shaft 3, and inserted into the linear shaft 1, the rear shaft 2 is supported to rotate the linear shaft 1, and the slider ( Move 4) up and down. When feeding the slider 4 to the uppermost part, the rod-shaped object is press-fitted and installed by the opening 1a of the linear shaft 1, and it pulls to the center and completes assembly. In this case, when the rod-shaped object is press-fitted in this way, there is no hygiene problem because the user does not perform the assembly work in the factory, and the assembly procedure is performed in a state in which the slider 4 is installed on the intermediate shaft 3 by a method other than the above. It is a good idea to press-fit the rod into the slider.

Hereinafter, the operation of the rotary rod-shaped article dispensing mechanism in the form of the above embodiment of the present invention, when the first rod is used in the state in which the rod-shaped object is accommodated in the shaft (1) while supporting the rear shaft (2) When rotating, since the intermediate shaft 3 is prevented from rotating by engagement of the coupling ribs 2c and 3f with respect to the rear shaft 2, the intermediate shaft 3 rotates together, and the engaging projection 4cc of the slider 4 is the linear shaft 1. In addition to being guided to the spiral groove (1c) of the), the engaging portion (4c) of the slider (4) is coupled to the slit (3a) formed in the longitudinal direction of the middle shaft (3), it is regulated by this slit (3a) to advance As a result, the rod-shaped object held by the slider 4 can protrude from the opening 1a of the front end of the linear shaft 1, and can be used.

In addition, since the slider 4 is restricted to the slit 3a of the middle shaft 3, it can only move to the front end thereof, so that the rod-shaped object is worn out excessively or excessively the linear shaft 1 with respect to the rear shaft 2 is exerted. Even if it passes through, the slider 4 will not advance further than necessary. Moreover, after use, the linear shaft 1 is rotated in the opposite direction to the above, and the rod-shaped object held by the slider 4 is easily accommodated in the linear shaft 12.

In addition, when the rod-shaped object worn out by use becomes impossible to use, the linear shaft 1, the intermediate shaft 3, and the slider 4 in which the remaining rod-shaped object was mounted are all unified, and this whole shaft is replaced by the rear shaft 2 The cassette of the new rod-like object may be removed from the front and inserted into the rear axle 2 from the front.

That is, the annular projection 1d and the annular recessed part which support the linear shaft 1 and the rear shaft 2 with different hands, pull them in different directions, and constitute the fitting means of the linear shaft 1 and the rear shaft 2 ( The fit of 2b) is lost. In addition, since the front end edge of the annular projection 3e of the middle shaft 3 is hung on the rear end surface of the linear shaft 1, the pulling shaft prevents the linear shaft 1 from coming off the central shaft 3, and as a result, In addition, the rod-shaped object holding mechanism other than the rear shaft 2, that is, the linear shaft 1, the middle shaft 3, and the slider 4 can be pulled out integrally as a cassette together with the rod-shaped object. Therefore, in this case, in particular, there is an advantage that the exchange with a new one is made without touching the rod directly, such as cosmetics.

FIG. 11 is a modified embodiment of FIG. 9, in which case the coupling ribs 2c of the rear shaft 2 are four and the coupling ribs of the middle shaft 3 are six, but the rotation prevention is the same as in the embodiment of FIG. 9. Function is achieved. That is, the coupling ribs 2c and 3f face each other and at the same time the side edges of one direction are in contact with each other and rotation is restricted.

FIG. 12 shows a form of another embodiment of the present invention, in which the slider 4 is idling at the top and the bottom while reducing the engagement tolerance between the parts. That is, in the form of the said embodiment, since there exists a considerable engagement tolerance around the rod-shaped object, in the case of especially a flexible eyeliner etc., it was easy to be broken by the impact by a fall.

According to the present embodiment, the slider 4 shown in Figs. 13 to 15 is used, and a retaining portion 4b having a rod-shaped object mounted on the front end thereof is formed to face the other end. The engaging portion 4c is formed. In addition, as shown in Fig. 14, the engaging portion 4c is provided with the engaging projection 4cc corresponding to the inclination of the spiral groove 1c formed in the inner circumferential portion of the linear shaft 1.

Accordingly, the engaging projection 4cc is coupled to the spiral groove 1c of the linear shaft 1 and the engaging portion 4c of the slider 4 is fitted into the slit 3a of the intermediate shaft 3. Accordingly, the rod-shaped object attached to the slider 4 and the slit 3a of the middle shaft 3 are removed, so that there is almost no coupling tolerance between the parts between the inner wall and the slider 4 and the linear shaft 1. Similarly, the coupling tolerance between the parts is reduced, and the shaking is reduced, so that there is a possibility that the rod-shaped object is broken and broken even in the impact of falling.

And, as shown in Figure 13, the rear portion of the slider (4) is formed in the longitudinal direction to face the divided grooves 4d, and thus, to rise or fall at the upper or lower limit of the moving range of the slider (4) When the rotation operation is performed, the projection 4cc of the slider 4 is forced inward in the radial direction by the inner wall of the linear shaft 1, but since the division groove 4d is present, the rotation operation in the direction of narrowing the division groove 4d is performed. Since the force is lost by doing so, the slider 4 is idling so that the parts are not broken.

As described above, since the structure of the present invention becomes the above-described process, the rod-shaped floating support portion is constituted by the cassette type, and the rod-like material can be exchanged without directly touching the rod-like object such as cosmetics. The number of parts is reduced to facilitate assembly and at the same time an effect such as good feeding operation can be obtained.

In particular, the cassette-shaped linear axis is shorter than the rear axis to improve operability, and at the same time, the user does not protrude the linear axis from the rear end of the linear axis as much as possible, and the user excessively protrudes from the linear axis to turn the rear end of the middle axis to extract the rod-shaped object. There is no effect.

In addition, since the assembling is easy and the coupling tolerance between parts is small, the rod-shaped object is not broken and broken by falling, and at the same time, even if an excessive rotation operation is performed beyond the limit, the slider is idle, thereby preventing the parts from being broken.
