Description

001
[Industrial application fields]
The present invention relates to a decorative material container including a cartridge and a container main body that house a rod-shaped decorative material so that the stick-shaped decorative material can be drawn out. In particular, there is no need for a push rod in the container body, and a single container body replaces a cartridge that automatically returns using a spring that constantly biases the core chuck member backward, and a cartridge that does not use a spring. The present invention relates to a cosmetic container that can be shared.
[0002]
[Prior art]
A cosmetic container of a type in which stick-shaped cosmetic materials such as eyeliner, eyebrow, eyeshadow, lip liner and lipstick contained in the cartridge are fed out from the opening opening of the cartridge by relative rotation of the cartridge and the container body is, for example, a patent This is proposed in Japanese Patent No. 3050548 and Japanese Patent Laid-Open No. 2000-135116.
[0003]
First, a cartridge type bar-shaped cosmetic material feeding container in which a push rod is inserted into the container body, and a stick-shaped cosmetic material is fed out when a cartridge is mounted on the container body and rotated relative to each other has been known for a long time. When the cartridge is mounted while the position of the push bar in the container main body is extended, the bar-shaped decorative material in the cartridge is unintentionally extended and an accident such as breakage of the bar-shaped decorative material may occur.
Japanese Utility Model Publication No. 5-13307 is disclosed as a supplement to such drawbacks.
[0004]
The above publication not only biases the core chuck member in the cartridge backward with a spring, but also winds a spring that biases the push rod in the container body backward, and when the cartridge is detached from the container body, It is an invention in which not only the core chuck member in the cartridge but also the push rod in the container main body can always be set to the initial position, and when the new cartridge is mounted on the container main body, the push rod in the container main body is always in the initial position. Therefore, it is an excellent invention in which the stick-shaped decorative material in the cartridge does not suddenly protrude and bend. However, in the invention described in this publication, a push bar is built in the container body, and the push bar is a stick-shaped decorative material in the cartridge. I was paying out timber.
[0005]
On the other hand, as a known example that does not require a push rod in the container body, there is Japanese Patent No. 3050548. In this publication, since the moving member provided with the decorative material holding portion at the front end in the cartridge is always urged backward by the spring, the stick-shaped decorative material is always lowered when the cartridge is pulled out from the container body. It can be pulled back to the initial position (retreat limit).
[0006]
For this reason, it is not necessary to project the stick-shaped decorative material from the cartridge and then rotate the rod-shaped decorative material to draw the stick-shaped decorative material into the front tube, and the stick-shaped decorative material is always in the initial position simply by pulling out the cartridge from the container body. Since it is pulled back, you can prevent accidents such as breaking or damaging the stick-shaped decorative material that was fed out during replacement.
[0007]
As described above, Japanese Patent No. 3050548 discloses a cosmetic container in which neither a push bar nor a spring exists in the container body. However, when the stick-shaped decorative material in the cartridge is detached from the container body, the container automatically returns to the initial position, and again the container. Even if it is attached to the main body, there is no push rod, so the stick-shaped decorative material in the cartridge does not suddenly protrude. In addition, since the spring exists only on the cartridge side, the configuration of the container body can be simplified, and this is an excellent invention that can be provided as an economical cosmetic material container.
[0008]
On the other hand, when the thickness of the stick-shaped decorative material inserted into the cartridge is extremely small, the stick-shaped decorative material must be held with a very small size, so that an impact such as a sudden pull-in with a spring or the like is applied. In order to avoid this, a cartridge that does not have an auto-return without a spring in the cartridge is safer. This non-auto-return cartridge is disclosed in FIGS. 8 and 9 of Japanese Patent Laid-Open No. 2000-135116.
[0009]
In this known example, the outer diameter of the casing can be reduced to match the rod-shaped decorative material. For example, if the thickness of the rod-shaped decorative material core is 1 mm, the thickness is 1 mm, and the thickness is 1,5 mm. The casing set to 1,5 mm can be held and accommodated in the cartridge.
Further, since a spring is not required as compared with a cartridge that automatically returns, the manufacturing cost is excellent.
[0010]
Furthermore, the absence of a push rod in the container body is one of the reasons that it is possible to hold and accommodate an ultrafine core cosmetic material such as an eyeliner or eyebrow in the cartridge. This is because the push rod in the container body enters the cartridge and pushes the stick-shaped decorative material core, so that the push rod is always required to be thinner than the stick-shaped decorative material.
In other words, in the case of a container body with a push bar, a bar-shaped decorative material having a thickness less than that of the push bar cannot be used on the cartridge side.
[0011]
As described above, when storing rod-shaped decorative materials having different materials and thicknesses, it is necessary to employ cartridges corresponding to the materials and the like. In particular, a cartridge that automatically returns the bar-shaped decorative material according to the physical properties of the bar-shaped decorative material and a cartridge that does not require auto-return can be used in common, and it does not have a push bar and does not affect the thickness of the bar-shaped decorative material. The need for a cosmetic container comprising a body has arisen.
[0012]
In addition, when the container body produces luxury, a metal appearance is preferable. In this case, a leaf spring is most suitable as an internal structure for holding the cartridge in view of ease of attachment.
However, the configuration of the external appearance of the cartridge is different between Japanese Patent No. 3050548 and Japanese Patent Laid-Open No. 2000-135116 in the above-described known example, and means for synchronously rotating the cartridge and the container body when storing the cartridge can be easily obtained. It cannot be used in common with a container body having a leaf spring.
[0013]
[Problems to be solved by the invention]
In view of the above problems, the present invention replaces and uses both a cartridge that automatically returns using a spring in a single container body, and a cartridge that does not use a spring containing a thin rod-shaped decorative material. Provided is a decorative container made up of a container body and a cartridge that can insert a push bar.
[0014]
[Means for Solving the Problems]
  In order to solve the above problems, in the first invention, a front tube having an opening hole through which a rod-shaped decorative material advances and retreats at a front end, a base body rotatably connected to the front pipe, the front tube and the base body A cartridge having means for axially moving a core chuck member provided with a decorative material holding portion for holding a stick-shaped decorative material at a front end inserted therein when rotated relatively, and a container body to which the cartridge can be attached In the decorative material container provided, the first cylinder includes the tip tube, the base, the core chuck member, and a spring that constantly urges the core chuck member rearward to position the cartridge in the backward limit when the cartridge is a single unit. A second cartridge comprising: the cartridge; the tip cylinder; the base; the core chuck member; and a means capable of stopping the core chuck member during the stroke when the cartridge is a single unit. And cartridge, the appearance of the first cartridge and the second cartridge and a base appearance portion of the base and knob portion of the leading tube, is furnished in the container body, With a part of the tipThe base appearance partWhenThe base spring and the container body rotate synchronously by a leaf spring that applies pressure to the plate spring, and the pressure applied by the leaf spring causes the core chuck member to advance and retract by the rotation of the leading tube and the container body. And a container main body capable of replacing the first cartridge and the second cartridge.
[0015]
In the second aspect of the present invention, the first cartridge and the second cartridge are formed on the base portion appearance portion of the first cartridge and the leaf spring in the container body that is fitted to the engagement portion. And an engaging portion.
[0016]
In the third invention, the base appearance portions of the first cartridge and the second cartridge are held by the leaf springs of the container body, and rotate synchronously with the container body. 3. A device according to claim 1, further comprising means for informing at the same time that the base of the cartridge and the leaf spring rotate relatively with respect to a rotational load at any one of the descending limits. The cosmetic container described.
[0017]
In a fourth aspect of the present invention, the leading cylinder of the first cartridge having a spring that constantly biases the core chuck member backward has a rotating portion that is accommodated in the container body, and the base of the cartridge is The leaf spring in the container body is rotated by the pressure of the leaf spring in the container body in synchronism with the container body, and the turning portion of the front tube receives the pressure of the leaf spring in the container body. And relative rotation.
[0018]
[Action and effect]
The first cartridge according to the first aspect of the present invention includes a spring that constantly urges the core chuck member rearward so that the core chuck member is positioned in the retreat limit when it is a single unit. When the core is removed, the lead chuck is automatically pulled back and can be automatically returned.
Further, since the second cartridge includes the leading cylinder, the base, the core chuck member, and means capable of stopping the core chuck member in the middle of the stroke when the cartridge is a single unit, the impact generated at the time of auto return. It is suitable for soft stick-shaped decorative materials and small-sized stick-shaped decorative materials, and since there is no spring, the manufacturing cost can be relatively reduced.
[0019]
Furthermore, since the external appearance of the first cartridge and the second cartridge includes the knob portion and the base external appearance portion of the leading cylinder, the first cartridge and the second cartridge can be replaced, and The container body and the base can be rotated synchronously by the frictional resistance caused by the pressure applied by the leaf spring, and the stick-shaped decorative material can be fed out.
[0020]
In addition, when the cartridge is attached to the container body, the length of the base external part below the part where pressure is applied by the leaf spring can be freely set, so the degree of freedom in designing the external appearance of the cartridge It is possible to provide a highly flexible cosmetic container capable of setting a stroke length suitable for a rod-shaped decorative material core, so that a rod-shaped cosmetic material with various physical properties can be provided. It is possible to realize a cosmetic container that can meet the requirements with a single container body.
[0021]
In the second invention, the leaf spring disposed in the container body includes an engaging portion, and the engaging portion is formed on the base of the first and second cartridges. By fitting, the cartridge and the container main body can be used with a stable rotation in the axial direction during use.
[0022]
In the third invention, the first and second cartridges hold their bases by leaf springs, the bases rotate in synchronism with the container body, and the bases at the feeding limit (upward limit, downward limit). Is rotating idly with respect to the leaf spring to prevent damage to the cartridge.
[0023]
As a result, even if the cartridge reaches the upper limit or the lower limit, it is set so that a clutch sound is generated between the cartridge and the leaf spring when a rotating force is applied to further extend or retract. Therefore, the user can clearly know the extension limit by the clicking sound of the tick and does not apply extra pressure to the cartridge.
[0024]
Therefore, it is possible to prevent accidents caused by carelessness such as kinking of the casing or destruction of the cartridge even with a very thin stick-shaped decorative material.
[0025]
In the fourth invention, the cartridge having a spring that constantly biases the core chuck member rearward is constituted by the front tube and the base, and the base is in contact with the leaf spring in the container body. The rotating portion of the front tube is also accommodated in the container body and is in contact with the leaf spring.
[0026]
The base body, of course, rotates synchronously with the container body while receiving the pressure of the leaf spring, but the turning portion of the front tube rotates relative to the leaf spring while receiving the same pressure.
[0027]
Therefore, even if a force that reversely rotates the leading cylinder by the spring works in the cartridge, the core chuck member in the cartridge moves to the retracting limit without permission because the rotating part of the leading cylinder is pressurized by the leaf spring. Can be prevented.
[0028]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0029]
1 to 3 show an embodiment of a first cartridge according to the present invention, and FIG. 1 shows a cosmetic container 1 in which a cartridge 2 (first cartridge) is mounted on a container body 3. FIG. 3 is a partial longitudinal sectional view of the cartridge 2, and FIG. 3 is a partial longitudinal sectional view of the container main body 3 that accommodates the cartridge 2.
[0030]
The cartridge of FIG. 2 will be described in more detail. The cartridge 2 rotatably connects the front tube 10 and the base 20, and a core chuck member 30 is slidably inserted therein, and the core chuck member 30 is provided with means for biasing backward by the spring 4. It has been taken.
[0031]
Further, the entire appearance of the cartridge 2 is as follows. The knob portion 14 of the front tube 10 that can be manually rotated when mounted on the container body 3, the rotating portion 15 that rotates within the container body 3, and the appearance of the base body. Part 26.
[0032]
The tip tube 10 is provided with a tip opening hole 11 at the tip, a plurality of sliding grooves 12 are provided in the inner axial direction, and a claw piece 32 forming a cosmetic material holding portion 31 at the tip of the core chuck member 30 is provided at the tip. The rod-shaped decorative material A is held between the claw pieces 32 in the sliding groove 12 of the cylinder 10.
[0033]
At the lower part of the claw piece 32, an engaging portion 33 that is engaged with the sliding groove 12 to constitute a rotation stop mechanism is provided, and a male thread 35 is provided with a stroke length on the housing 34 that extends further downward. A stopper member 40 is attached to the rear end.
[0034]
The base body 20 is rotatably connected to the front tube 10, and a female screw portion 21 that engages with the male screw 35 of the core chuck member 30 is provided at the front portion, thereby constituting a screw engagement mechanism with the core chuck member 30. is doing.
[0035]
The spring 4 is a push spring, and is interposed between the female threaded portion lower end surface 24 of the female threaded portion 21 at the front of the base body 20 and the stopper member 40, and constantly biases the core chuck member 30 backward.
[0036]
As shown in FIG. 3, the container body 3 that accommodates the cartridge 2 has an outer cylinder 50 having a front end opening hole 51 that can accommodate the cartridge 2 at the front end, and a pressure applied to the base outer appearance portion 26 of the cartridge 2. And a leaf spring 5 for holding the cartridge 2.
[0037]
In FIG. 3, a spring separating rod 71 for separating the spring 4 in the cartridge 2 at the time of disposal is provided separately, and the rear end is covered with a tail plug 60.
[0038]
The leaf spring 5 in the container body 3 includes an engaging portion 5a that is engaged when the cartridge 2 is accommodated.
Further, the leaf spring 5 is held in the container body 3 between the R portion 53 and the spring separating member 70 so that the leaf spring 5 does not escape from the tip opening hole 51 by inserting and removing the cartridge 2.
[0039]
Next, with reference to FIG. 1, the operation of the rod-shaped decorative material A moving forward and backward when the cartridge 2 is attached to the container body 3 and the leading tube 10 and the container body 3 are rotated will be described.
[0040]
First, when the cartridge 2 is inserted from the tip opening hole 51 of the container body 3, the cartridge 2 is pushed in while receiving the pressure of the leaf spring 5, and the engaging portion 23 of the base body 20 of the cartridge 2 is engaged with the engaging portion 5 a of the leaf spring 5. Mating.
[0041]
In this state, when the knob portion 14 of the cartridge 2 and the container main body 3 are rotated relative to each other, the base 20 rotates synchronously with the container main body 3 due to the frictional resistance caused by the pressure of the leaf spring 5, so that the cartridge 2 is eventually obtained. The front tube 10 and the base 20 are rotated.
[0042]
The male screw 35 of the core chuck member 30 and the female screw portion 21 of the base body 20 constitute a screwing mechanism, and the engaging portion 33 of the core chuck member 30 is engaged with the sliding groove 12 of the front tube 10 on the front tube 10 side. When the leading cylinder 10 and the base body 20 are rotated relative to each other to form a rotation stopping mechanism, the core chuck member 30 moves in the axial direction while rotating synchronously with the leading cylinder 10, and the core chuck member 30. The rod-shaped decorative material A held by the front decorative material holding portion 31 advances from the front end opening hole 11 of the front tube 10.
[0043]
Moreover, the rod-shaped decorative material A moves backward by the mechanism by rotating the front tube 10 and the container body 3 in the opposite direction to the above.
[0044]
Since the cartridge 2 includes the spring 4 that constantly biases the core chuck member 30 backward, the cartridge 2 is a spring 4 when the cartridge 2 is pulled out from the container body 3 with the stick-shaped decorative material A protruding. The core chuck member 30 is positioned at the retreat limit while the base body 20 is rotated by the urging force.
[0045]
That is, the consumer does not have to perform the operation of pulling out the protruding stick-shaped decorative material, and it is a convenient function that the stick-shaped decorative material A is returned to the lower limit by simply pulling out the cartridge 2 from the container body 3.
[0046]
Further, when the cartridge 2 is accommodated in the container body 3 and rotated to move the core chuck member 30 in the axial direction, the urging force of the spring 4 becomes stronger as it moves (closer to the upper limit of feeding). And the base 20 are automatically rotated relative to each other (idle rotation) to automatically pull back the core chuck.
[0047]
Therefore, as shown in FIG. 1, the leaf spring 5 in the container body 3 imparts friction resistance to the base body 20 by the pressure of the leaf spring 5 and at the same time applies pressure to the rotating portion 15 of the front tube 10 to cause friction. Giving resistance.
More specifically, since the leaf spring 5 can apply pressure to the contact portion, the portion where the leaf spring 5 is in contact with both the rotating portion 15 and the base body appearance portion 26 of the cartridge 2 is provided. By applying pressure to both of the outer appearance portions 26 and applying frictional resistance, when the cartridge 2 is stored in the container body 3, the leading cylinder 10 and the base body 20 are idly rotated and the core chuck member 30 is freely retracted. It prevents that it moves to.
[0048]
Further, the leaf spring 5 is provided with an engaging portion 5a, and the cartridge 2 is provided with an engaging portion 23 to be engaged therewith, thereby giving resistance when the cartridge 2 is removed from the container body 3, and in normal use the cartridge 2 2 and the container body 3 have the advantage that they can be used stably in the axial direction, but are omitted if the pressure of the leaf spring 5 is sufficient to hold the cartridge 2. It doesn't matter.
[0049]
4 to 7 show an embodiment of the second cartridge of the present invention. The container body 3 of the cosmetic material container 101 of this embodiment is the same as the container body 3 shown in FIG. Is.
[0050]
The most different part between the second cartridge 102 of the present embodiment shown in FIG. 6 and the first cartridge of FIG. 1 is that there is no spring for urging the core chuck member 130 backward, The rod-shaped decorative material B used is a relatively thin core material.
[0051]
Also in the screwing mechanism, a group of protrusions 135 are scattered on the housing 134 of the core chuck member 130 so as to draw a spiral, and the front portion of the base 120 is a female screw portion 121 screwed into the spiral. Thus, a screwing mechanism is configured.
[0052]
Further, an O-ring 6 is wound around a concave groove provided on the outer periphery of the front portion of the base body 120, and friction resistance due to appropriate friction is given between the front tube 110 and the core chuck member is stopped during the stroke when the cartridge is a single unit. It is possible.
This is to prevent the rod-shaped decorative material B from protruding from the front end opening hole 111 due to vibration of the front tube 110 and the base body 120 due to vibration or the like during the sale of the cartridge alone or the accompanying transportation. .
[0053]
The operation of the decorative material container 101 in a state where the second cartridge 102 of the present embodiment is accommodated in the container body 3 will be described.
[0054]
In addition, about a container main body, it demonstrates with the number attached | subjected to the container main body 3 shown by FIG.
[0055]
The cartridge 102 is inserted from the distal end opening hole 51 of the container body 3, the base body appearance part 126 is inserted while receiving the pressure of the leaf spring 5, and the engagement part 123 is engaged with the engagement part 5 a of the container body 3. The dressing is completed.
[0056]
When the outer cylinder 50 and the knob portion 114 of the cartridge 102 are rotated relative to each other, the base 120 rotates synchronously with the container body 3 due to the frictional resistance caused by the pressure of the leaf spring 5, so that the front cylinder 110 and the base 120 of the cartridge 102 are eventually And the engaging portion 133 below the decorative material holding portion 131 of the core chuck member 130 engages with the sliding groove 112 in the leading tube 110 to form a rotation stopping mechanism. .
Further, on the base 120 side, a group of protrusions 135 are screwed into the female threaded portion 121 of the base 120 to form a screwing mechanism, so that the rotation prevention mechanism and the screwing mechanism are rotated by the rotation of the front tube 110 and the base 120. The core chuck member 130 moves in the axial direction while rotating synchronously with the front tube 110, and the bar-shaped decorative material B held between the claw pieces 132 of the core chuck member 130 is moved to the front tube 110. Projection starts from the front end opening hole 111 of the.
[0057]
If the protrusion 135 on the core chuck member 130 is configured to engage with the sliding groove 112 on the front tube 110 side when screwed into the female thread portion 121 of the base body 120, the thickness of the housing 134 is substantially a rod shape. Since it can be the thickness of the decorative material, it is more suitable for a thin rod-shaped decorative material.
[0058]
Note that the rod-shaped decorative material B to be inserted can safely hold a thinner or softer core material than the rod-shaped decorative material A of FIG.
[0059]
In the present embodiment, the relationship between the plate spring 5 in the container body 3 and the cartridge 102 is as shown in FIG. 5. The engaging portion 123 of the base body 120 of the cartridge 102 with the plate spring is formed as a polygonal portion 123a. .
[0060]
However, in the lower limit shown in FIG. 4, when the force to further rotate and draw out the rod-shaped decorative material B or the upper limit is applied, it is the upper limit or the lower limit. It is desirable to have a means of informing.
[0061]
Therefore, in the present embodiment, a polygonal portion 123a is formed on the cartridge 102 side at the portion where the leaf spring 5 in the container body 3 and the contact portion 5b of the cartridge 102 are in contact with each other. In this case, the cartridge 102 is rotated and clutched with respect to the leaf spring 5 in the container main body 3 when a lowering force is applied below the lower limit.
[0062]
At this time, the cartridge 102 is rotated with respect to the leaf spring 5 to make a tick and a clutch sound to notify the user of the extension limit.
[0063]
Of course, the engaging portion 23 of the first cartridge 2 shown in FIG. 1 may be formed into a polygonal shape as in the second embodiment, and this clutching method may be used.
[0064]
However, in the upper limit of the first cartridge shown in FIG. 1, the flat portion 36 of the housing 34 is located on the female screw portion 21 of the base body 20, and at this time, the rear end of the male screw is urged by the downward biasing force of the spring 4. Since 35a is clutched and dropped into the spiral groove of the female threaded portion 21 of the base 20, a tick is made every time it is rotated, so that the rising limit is notified. Therefore, the clutch provided in the cartridge 2 is effective for the rising limit. Therefore, the clutch mechanism is effective only at the lower limit.
[0065]
In FIG. 5 of the present embodiment, a polygonal shape 123a is used as a clutch mechanism on the base of the cartridge 102 with respect to the contact portion 5b of the leaf spring 5. However, as shown in FIG.5CAnd the spline 123b for engaging the cartridge side with the cartridge may be formed.
[0066]
In any case, when a rotational force greater than the frictional resistance due to the pressure of the leaf spring 5 is applied to the cartridge 102, the cartridge 102 rotates idly with respect to the leaf spring, and clutches to inform the user of the rod 102 The purpose is to protect the decorative material.
[0067]
Further, the clutch mechanism is not limited to the engaging portion 5a of the leaf spring 5, and a clutch mechanism may be provided in a portion other than the engaging portion 5a. For example, FIG. When the convex portion 73a that forms the portion 125 and is bent from the upper end surface 73 of the spring separating rod 70 of the container body 3 is brought into contact with the concave and convex portion 125, and the rotational force is applied beyond the lower limit of feeding of the cartridge 102, The base 120 rotates idly with respect to the leaf spring 5, and a convex piece 73 a formed on the upper end surface 73 of the spring separating rod 70 and deformable and bends forms an uneven portion 125 at the rear end of the base 120 of the cartridge 102. A method of clutching by bend and sliding to make a clicking sound continuously and informing the user of the extension limit may be used.
[0068]
Thus, the clutch mechanism having the function of the protection mechanism may be provided not only between the leaf spring and the cartridge but also between the container body and the cartridge.
[0069]
The cartridge 102 of FIG. 6 in this embodiment forms a protrusion 135 on the housing 134 of the core chuck member 130 to form a screwing mechanism, but of course it is not limited to this feeding mechanism, When the base 120 is rotatably connected and accommodated in the container main body 3, the base 120 of the cartridge and the container main body 3 rotate synchronously by the pressure applied by the leaf spring 5 to the external appearance of the base. Any mechanism may be used as long as the feeding mechanism in the cartridge 102 works to feed the stick-shaped decorative material, and the cosmetic material container comprising the cartridge and the container body of the present invention does not limit the structure in the cartridge.
[0070]
In the first cartridge 2 of the above embodiment, the leaf spring 5 is used as a means for preventing the leading cylinder 10 and the base body 20 from idling due to the repulsive force when the spring 4 is contracted. However, without being limited to this, friction means such as an O-ring may be separately provided between the front tube 10 and the container body 3 to prevent idling.
[0071]
In the present embodiment, the cartridge having the base appearance portion accommodated in the container body 3 is thick enough to allow the core chuck member inserted into the front tube and the base body to be maximally allowed from the cartridge in which the ultrafine core material is inserted. Up to the cartridge in which the core material can slide can be shared by the same container body, and the first cartridge automatically returns when the core is pulled out from the container body 3 by the spring. There are no springs inside the cartridges, which are suitable for thin cores, but these cartridges are replaceable container bodies 3 that can be used as leaf springs in the container bodies against loads at the ascending limit and descending limit. It is an excellent invention that can also employ a protection device for stick-shaped decorative material by means of idling and notifying the user of this.
