Description

[Detailed Description of the Invention] This invention relates to a mascara container in which the amount of application can be adjusted.

Conventionally, with this type of mascara container, the application liquid adhering to the applicator rod is scraped off at the edge of the mouth of the container to adjust the appropriate amount. This was extremely difficult to use as there was a risk that the liquid would spill out and stain the entire container. As an alternative to this, it is known that a coating amount adjustment mechanism is attached to the mouth of the container to squeeze the coating liquid adhering to the applicator stick and adjust the amount to an appropriate amount. Since the opening is located at the opening, there is a risk that the application liquid adhering to the opening may stain the hands and fingers during adjustment operations. Furthermore, a container disclosed in Japanese Patent Application Laid-Open No. 54-88445 has another adjustment mechanism, in which the bottle can be adjusted by twisting the end of the bottle that protrudes at the tail end with respect to the bottle cover. Rotate up and down,
The diameter of the wiper orifice is adjusted by increasing or decreasing the force with which the wiper at the tip comes into contact with the overhang provided on the bottle cover, but since this container rotates and moves the bottle up and down, the length of the operating grip is limited. The wiper can't be operated smoothly as it changes length and short, and the wiper at the tip comes into rotational pressure contact with the protruding part due to the rotating motion of the bottle, so it is not durable.Furthermore, the airtightness between the bottle and the bottle cover is not considered at all. However, there are problems such as the coating liquid evaporates and cannot withstand long-term use.

Therefore, this invention was devised in view of the above-mentioned drawbacks and problems. An inner case that is airtightly fitted to the case, stores a coating liquid therein, and has an elastic ironing member at its tip; and an adjusting means that presses against the overhanging member to change the hole diameter of the ironing member. A feeding mechanism is installed between the outer case, the tail plug, and the inner case to allow the inner case to slide up and down in a straight line, and an applicator rod that is inserted through the ironing member and immersed in the coating solution is attached to the opening of the outer case. By using a cap that can be airtightly attached to and removed from the cap, it is possible to quickly and accurately adjust the amount of coating liquid to the desired amount. The purpose of this invention is to provide a mascara container that can be used for a long period of time by reliably preventing evaporation of the mascara.

An embodiment of the configuration of this invention shown in the drawings will be described in detail below.

is press-fitted into the gap between the small diameter portion 16 of the stopper 13 and the inner surface of the tip end of the inner case 9, and the second airtight rib 26 is pressed against the inner wall surface of the inner case 9, whereby the stopper 13 and the inner case 9 are separated. Block the ventilation path from the mating part. Further, when the inner case 9 is fitted into the outer case 1, the first airtight rib 25 comes into pressure contact with the inner wall surface of the outer case 1, and blocks the ventilation path at the fitting portion between the stopper 13 and the outer case 1. On the other hand, the rear part of the inner case 9 is formed to have a small diameter, and the outer peripheral surface is provided with 11/4 pitch screw grooves 27 as shown in FIG. Engagement recess 2
form 8. Reference numeral 29 is a tail plug, which consists of a grip part 30 that is a short cylinder with a bottom, and four operation pieces 31 extending at equal intervals at the tip thereof. A fitting protrusion 32 is provided to rotatably fit into the screw groove 27, and an engaging protrusion 33 is provided on the inner surface to fit into the screw groove 27, as shown in FIG. Further, a mark 34 is provided on the tail plug 29 and a scale 35 is provided on the rear end of the outer case 1, and the rotation angle is adjusted by suitably matching these marks.

form.

With this structure, the inner case 9 is fitted into the outer case 1, the tail plug 29 is rotatably fitted into the outer case 1, and the tail plug 29 is screwed into the inner case 9.
Further, the cap 36 is screwed into the opening 4 of the outer case 1, and the coating rod 38 is passed through the squeezing member 19, and the brush 41 at the tip thereof is dipped in the coating liquid in the inner case 9 and stored. When using this,
By rotating the tail plug 29, this tail plug 29
The threaded groove 27 of the inner case 9 that is threadedly engaged with the engagement protrusion 33 of the operating piece 31 is actuated, and the guide groove 7 of the outer case 1 is activated.
The engaging protrusion 10 is moved along the inner case 9 to move the inner case 9 forward linearly in the longitudinal direction within the outer case 1. As the inner case 9 moves forward, the adjustment plate 21 of the squeezing member 19 fixed at the tip of the outer case 1 is moved by the protruding member 6 of the outer case 1.
Since the iron is pressed against the iron, its elasticity enlarges the central ironing hole 20. When the cap 36 is removed and the coating rod 40 is pulled out in this state, the coating liquid adhering to the brush 43 at the tip is squeezed slightly by the expansion of the threading hole 20, and the coating rod 40 containing a large amount of coating liquid is taken out. be able to. Also, to take out a small amount of coating liquid, rotate the tail plug 29 in the opposite direction.
Contrary to the above, the inner case 9 moves backward, and the pressing force of the overhanging member 6 on the adjustment plate 21 of the ironing member 19 at its tip decreases, so the central ironing hole 20 contracts due to its elasticity, causing the coating to be applied. When the rod 40 is pulled out, the coating liquid on the brush 43 at the tip is strongly squeezed, and a small amount of the coating liquid can be taken out into the coating rod 40. In adjusting the amount of application, the engagement protrusion 32 provided on the operation piece 31 of the tail plug 29 fits into the recess 28 provided in the threaded groove 27 of the inner case 9 as the tail plug 29 rotates, and is further rotated. As a result, it moves into the screw groove 27 and rotates intermittently with a light resistance so as to fit into the next recess 28. In the case of the embodiment, since it engages intermittently at three positions, the diameter of the straining hole 20 of the straining member 19 can be changed in three stages, and the amount of adjustment can be easily set. However, when adjusting not only to these three adjustment positions but also to an intermediate position, it is sufficient to align the mark 34 with the scale 35.

Next, FIGS. 5 to 7 show a second embodiment, in which the feeding mechanism provided between the outer case, the tail plug, and the inner case in the first embodiment is further improved, and the ironing hole of the ironing member is opened. The variable range can be set arbitrarily, and specifically, the outer case 5
1 has a protruding member 54 at the inner end of a mouth portion 53 having a screw 52 carved therein, a guide groove 55 on the inner wall surface of the central part, and a ring-shaped groove 56 near the bottom, as in the first embodiment.
form. The inner case 57 has a hole 58 at the tip.
It has an ironing member 59 with a perforation, and an engaging protrusion 60 is formed on the outer circumferential surface of the central part, but a 3-pitch thread 61, which is longer than the first embodiment, is formed on the rear part.
A part of the rear end outer circumferential surface 62 is removed 63, and an arc-shaped slide recess 65 is provided with stoppers 64a and 64b formed at both ends. 66 is installed protrudingly. The adjuster star 67 has an operating piece 68 protruding from its annular base, a fitting protrusion 69 that rotatably fits into the groove 56 of the outer case 51 on the outer wall surface of the operating piece 68, and a fitting protrusion 69 on the inner surface. Case 5
An engaging protrusion 70 that engages with the thread 61 of No. 7 is provided in a protruding manner. Furthermore, a ring-shaped protrusion 71 is provided on the base, and a knurling 72 is carved on the outer peripheral surface. The tail plug 73 is formed in the shape of a short cylinder with a bottom, and has a ring-shaped fitting groove 74 that fits into the protrusion 71 of the adjuster star 67 and a knurl 75 that engages with the knurl 72 on the inner circumferential surface. An arcuate engagement protrusion 76 is provided on the bottom surface with a space between it and the inner circumferential surface. The rest of the structure is similar to that of the first embodiment.

With this configuration, the outer case 51
The inner case 57 is fitted inside, and the fitting protrusion 69 of the operating piece 68 of the adjuster star 67 is rotatably fitted into the groove 56 of the outer case 51, and the engaging protrusion 70
is engaged with the thread 61 of the inner case 57. Then, the adjuster star 67 is rotated to move the inner case 57 back and forth, and the tip of the straining hole 58 is pressed against the overhanging member 54 of the outer case 51 to set the opening diameter to a desired hole diameter. Next, fit the knurl 72 of the tail plug 73 into the knurl 72 of the adjuster star 67,
The protrusion 71 is fitted into the fitting groove 74 to fix them together, and the engagement protrusion 76 of the tail plug 73 is engaged with the slide recess 65 to assemble. When using this, the tail plug 73 is rotated to rotate the adjuster star 67 which is integrally connected to the tail plug 73.
1, the inner case 57 moves back and forth. At the same time, the engagement protrusion 76 erected on the tail plug 73 is connected to the stopper 6 at the left end of the slide recess 65.
The inner case 57, which abuts on the right end stopper 64b, rotates from the position where the circular case 4a is moved backward, to the position where the inner case 57 abuts the right end stopper 64b. For example, the hole diameter of the ladder hole 58 can be set to 2.8 mm in the retracted position and 3.3 mm in the forward position, and can be applied to materials with relatively low viscosity after coating. can. In addition, since the engaging protrusion 76 rotates over the rib 66, the amount of feeding can be easily set without intermittently generating a light resistance force. Furthermore, if the viscosity of the coating liquid is high or the brush of the coating rod is large, during assembly, rotate the adjuster star 67 from the above position to advance the inner case 57 and press the squeezing member 5.
9, insert the straining hole 58 into the overhanging member 54 of the outer case 51.
The tail plug 73 is attached to the adjuster star 67 in a state in which the diameter of the ironing hole 58 is expanded by pressing the tail plug 73 more firmly against the
Fit and secure. When assembled in this way, when the tail plug 73 is rotated, the engagement protrusion 76 rotates between the left and right stoppers 64a, 64b, and the position where the inner case 57 moves back and forth is from the set position described above. Move back and forth in the fully advanced position, for example, set the diameter of the ironing hole 58 to 3.0 mm in the retracted position,
It can also be set to be variable to 3.5mm in the forward position.

As described above in detail in each embodiment, this invention allows for easy adjustment because the tail plug at the rear end of the outer case rotates without changing its length in the vertical direction.
In addition, since the diameter of the ironing hole can be freely changed and adjusted by operating the tail plug, it is possible to adjust and use the ironing hole cleanly without touching the opening that is contaminated with the application liquid, and the Since the member and the overhanging member are pressed back and forth without being twisted, the ironing member does not wear out and can be used for a long period of time. Furthermore, since the inner case is prevented from rotating relative to the outer case and is allowed to slide up and down, the first airtight rib provided between the inner case and the outer case acts reliably to ensure that the coating liquid evaporates. It can be prevented. Furthermore, the hole diameter of the ironing hole can be freely set to a predetermined hole diameter for various different viscosity and properties of the coating liquid, shape and material of the applicator, etc., so it can be manufactured at low cost without the need to prepare various parts. This has the effect of making it possible to obtain a mascara container that is easy to use.
