[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cosmetic container using a straight tube as a main body for accommodating cosmetics, and is particularly intended to improve the feeling of dispensing.

[0002]

[Prior art]

 A so-called throttling tube in which a flat plate is narrowed to form a cylindrical body has a drawback that the number of steps is large. If the number of steps is large, it is very difficult to make the cylinder a perfect circle. Therefore, it is conceivable to use a drawn straight tube for the main body 101 in order to reduce the number of steps and thereby improve the dimensional accuracy, the dimensional stability, and the feeding / feeding performance. A conventional cosmetic container using a straight tube as a main body has a structure as shown in FIG. 14, for example.

That is, first, there was the hakama cylinder 100, and the main body 101 was coaxially arranged on the inner peripheral side of the hakama cylinder 100 with a gap. A filling 103 was attached between the center of the main body 101 and the hakama barrel 100. An outer cylindrical body 105 having a spiral groove 107 provided in a spiral shape on the inner peripheral surface was arranged between the hakama cylinder 100 and the main body 101. The inner plate 109 was arranged on the inner peripheral side of the main body 101. The inner plate body 109 is such that the projections 111, 111 provided at the lower end portion are screwed into the spiral groove 107 through the slide holes 113, 113 provided at the lower portion of the main body 101. Reference numeral 115 is a sliding portion. Cosmetics are accommodated and held in the inner dish 109, and the hakama barrel 100 is rotated so as to be dispensed and dispensed. In this case, the outer cylindrical body 105 was fitted in the main body 101, and the inner tool 103 was fitted in the outer cylindrical body 105 and the main body 101, respectively. Therefore, if there are variations in the cylinder diameters of the main body, the outer cylinder, and the filling, there are the following drawbacks.

[0004]

[Problems to be solved by the device]

 That is, when the diameter of the filling 103 is smaller than the appropriate size, the sliding resistance between the main body 101 and the outer cylindrical body 105 in the sliding portion 115 becomes too large. For this reason, there is a drawback in that the feeding and feeding becomes heavy and it cannot be carried out smoothly.

Further, if the diameter of the filling 103 is larger than the appropriate size, the sliding resistance between the main body 101 and the outer cylindrical body 105 in the sliding portion 115 becomes too small. For this reason, there are drawbacks such that there is rattling during feeding and feeding, and the feeding and feeding becomes too light and the feeding feeling becomes poor.

[0006] When a straight tube is used for the main body as described above, smooth feeding / pulling-in and a good feeding feeling can be obtained unless the dimensional accuracy of the constituent members such as the main body, the outer cylindrical body, and the filling is accurate. There was a drawback that you couldn't. By the way, in the past, by injecting silicone oil, etc., we have aimed to prevent rattling and improve feeding and feeding. However, silicone oil and the ingredients of cosmetics are chemically incompatible, and the use of silicone oil was not desirable.

The present invention has been made in view of such a background. That is, an object of the present invention is to achieve good feeding / placing in a cosmetic container using a straight tube as a main body.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a straight main body having an open upper and lower body and a sliding hole provided in the lower portion along the longitudinal direction, and a body having an open upper and lower body and the main body is slidably fitted inside. And has a rotatable outer cylindrical body having a spiral groove on the inner peripheral surface, and a protrusion formed of a cylindrical body and slidably engaged with the spiral groove through the sliding hole. In a cosmetic container comprising an inner plate body for accommodating and holding cosmetics, and an inner ingredient attached to the outside of the main body, an action part is formed on the upper part of the outer cylinder body, and the action part is Provided is a cosmetic container characterized in that it is arranged with a gap between the tool and the main body, and the action part is rockably contacted with the inner tool so as to be able to swing when sliding. At this time, it is conceivable that a rib is provided on the outer peripheral surface of the action portion along the circumferential direction, and the rib is slidably abutted on the inner peripheral surface of the inner tool in the circumferential direction. Further, it is conceivable to provide the ribs in a dot shape. Further, it is conceivable to provide the ribs endlessly. Further, it is conceivable that the upper end portion of the action portion is expanded to the filling side. Further, it is conceivable that a projection is provided on the inner peripheral surface of the upper end of the lower part of the inner tool along the circumferential direction so as to slidably contact the outer peripheral surface of the acting portion in the circumferential direction. Further, it is conceivable to provide the protrusions in a dot shape. In addition, it is conceivable to provide the protrusions endlessly.

[0009]

[Action]

 The relationship between the sliding resistance and the feeding / feeding in the sliding portion of the cosmetic container according to the present invention is as follows.

First, the variation in size between the sliding portion of the main body and the upper portion (action portion) of the outer cylinder and the lower portion of the inner tool is absorbed by the spring effect of the action portion. That is, the working portion is appropriately deformed in the gap surrounding the sliding portion, so that variations in the dimensions of the sliding portion of the main body and the lower portion of the working portion and the inner part are absorbed. Regarding the sliding resistance and the feeling of extension, this is due to the spring effect of the action part, and the working part is always in contact with the sliding part with an appropriate elastic force. Receive the movement smoothly. For this reason, it is possible to perform feeding and feeding with an appropriate weight (friction force) by the set optimum resistance.

A pair of protrusions 15 and 15 are provided at symmetrical positions at the lower end of the inner plate body 13, and the pair of protrusions 15 and 15 are screwed into the spiral groove 11 through the sliding hole 4 described above. It is supposed to do. The cosmetic material 37 is accommodated and held in the inner plate body 13. Reference numeral 16 is a ridge provided to prevent the cosmetic material 37 contained and held from falling off.

The fitting relationship between the main body 3, the inner component 7, and the outer tubular body 9 will be described in more detail with reference to FIG. The upper part of the outer cylindrical body 9 is formed as an action part 17 with a part surrounding the sliding part 5 from the upper end. The acting portion 17 is swingably arranged between the lower portion 8 of the inner tool 7 and the main body 3. That is, a sliding groove 20 is provided in the acting portion 17, the sliding portion 5 is surrounded by the sliding groove 20, and an endless rib 19 is provided on the outer peripheral surface of the upper portion so as to project in the circumferential direction. The rib 19 is slidably contacted with the inner peripheral surface of the lower part 8 of the inner tool in the circumferential direction. G is a gap provided between the action part 17 and the sliding part 5 and the lower part 8 of the inner tool. The hakama cylinder 1 and the filling 7 are ultrasonically welded to each other at the top of the hakama cylinder 1. The portion ultrasonically welded is shown at 47. In addition, a slit 24 is appropriately provided on the upper portion of the outer cylinder body 9 for assembling and fitting with the main body 3, as shown in FIG. 1A. It should be noted that a slit 24 is appropriately provided on the upper portion of the outer cylindrical body 9 for assembly and fitting with the main body 3, as shown in FIG. 1A.

The upper portion 6 of the filling 7 is detachably fitted between the inner cap 29 fixed to the cap 27 and the main body 3 so as to be airtight. That is, a protrusion 31 that is curved in an annular shape is provided on the outer peripheral surface of the upper portion of the inner component 7, and the protrusion 31 is fitted into the corresponding recess 33 of the inner cap 29 to form the fitting portion 35. There is. The lower end 30 of the inner cap 29 is widened so that the inner component 7 can be easily attached and detached.

The cosmetic material 37 is stored in the cosmetic container having the above-described structure by filling the molten cosmetic material through the holes 2. In the case of the bottom filling type, after filling the cosmetic, a sticker is attached to the hole 2 on the bottom surface of the hakama barrel 1. After the cosmetic is solidified, the molding tool is removed and the cap 27 is fitted.

Reference numeral 39 in the figure denotes an outer protrusion provided at the center of the inner tool 7.

With respect to the materials of the respective constituent members, in the case of the above-mentioned embodiment, the hull cylinder 1, the inner component 7, and the cap 27 are made of, for example, acrylonitrile-styrene copolymer resin (AS resin), and the main body 3 is made of, for example, aluminum. Each of them is composed of such metals. The outer cylinder 9 is made of, for example, polyacetal (POM), the inner plate 13 is made of, for example, polybutylene terephthalate (PBT), and the inner cap 29 is made of a thermoplastic resin such as linear low-density polyethylene (LLDPE). Each is composed.

Based on the above configuration, its operation and effect will be described with reference to FIGS. 3 to 5. FIG. 3 shows a case in which the sliding portion 5 of the main body 3 tries to rattle in the radial direction shown by the arrow when the hakama cylinder 1 is rotated and the outer cylinder 9 is slid for feeding and feeding. Show. In such a case, the acting portion 17 is bent and deformed in the gap G surrounding the sliding portion 5, the rib 19 is elastically contacted with the lower part 8 of the inner tool, and the sliding groove 20 is formed in the sliding portion 5. Is covered and is slidably contacted with this. FIG. 4 shows a case where the sliding portion 5 of the main body 3 tries to rattle in the upward direction indicated by the arrow. In such a case, the action part 17 is bent and deformed in the gap G surrounding the sliding part 5, the rib 19 is slidably abutted on the lower part 8 of the inner tool, and the upper part of the sliding groove 20 is formed. The inner wall is in sliding contact with the upper portion of the sliding portion 5. FIG. 5 shows a case where the sliding portion 5 of the main body 3 tries to rattle in the downward direction shown by the arrow. In such a case, the acting portion 17 is bent and deformed in the gap G surrounding the sliding portion 5, the rib 19 is slidably abutted on the lower part 8 of the inner tool, and the lower portion of the sliding groove 20 is formed. The inner wall is brought into sliding contact with the lower portion of the sliding portion 5.

As described above, the acting portion 17 acts just like a spring, and swings between the main body 3 and the lower portion 8 of the inner implement while appropriately deforming according to the size of the sliding portion 5 and whether the sliding portion 5 is wide or narrow. Therefore, the variation in the dimensions of the sliding portion 5 and the vertical movement of the sliding portion 5 during sliding are completed in the movement associated with the elastic contact of the action portion 17. For this reason, the sliding resistance between the main body 3 and the lower part 8 of the inside of the sliding portion 5 does not increase or decrease. Therefore, the container can be delivered and dispensed without rattling, and can be performed smoothly under a set optimum condition and with a good delivery feeling.

Further, the cap 27 is provided with the inner cap 29, and the protrusion 31 of the upper part of the filling 7 is pressed against the recess 33 side of the inner cap 29, so that the adhesion of the fitting portion 35 is further strengthened. To be done. As a result, the airtightness of the entire container is further increased.

As described above, according to this embodiment, it is possible to improve the feeding and feeding. Further, since the airtightness can be improved, even when it is used as a container for cosmetics containing a large amount of volatile components, a good usability state is maintained for a relatively long period of time. (Phenomenon that comes off from the middle dish as a result of shrinkage), "Wake up" (Phenomenon that cannot effectively respond to feeding / placing cosmetics), "Fold" (Easy breakage of cosmetics as a result of shrinkage) It is possible to prevent the phenomenon of breaking.

Further, even if the accuracy of the diameter of each cylinder such as the outer cylinder, the filling and the main body varies to some extent, it is absorbed by the working portion 17, which affects the smooth feeding / feeding and the feeling of feeding. There is no such thing.

The cosmetic container according to the present invention is not limited to the above embodiment. For example, the rib 19 may be provided in an endless shape or in a dot shape.

Further, when fitting the inner tool 7 and the outer tubular body 9, as shown in FIG. 6, the upper end 10 of the acting portion 17 is expanded to the inner tool 7 side instead of the rib 19, Even if it comes into contact with the inner peripheral surface of the tool 7, the same action and effect as those of the first embodiment are obtained.

Similarly, instead of the rib 19, a protrusion 22 may be provided along the circumferential direction on the inner peripheral surface of the upper end portion of the lower part 8 of the inner implement so as to contact the outer peripheral surface of the action portion 17 (FIG. 7). ), And the same operation and effect as the first embodiment. The protrusion 22 may be provided in a dot shape or an endless shape. Further, as shown in FIG. 8, the wall thickness of the wall surface of the inner tool 7 may be partially formed to be large (indicated by reference numeral 23) to replace the protrusion 22.

The shape and form of the outer shape of the inner plate body 13 is arbitrary. For example, the external shape is elliptical in cross section (Fig. 9), the protrusions 13a, 13a are provided at symmetrical positions on the outer circumferential surface in the longitudinal direction from the upper end to the lower end (Fig. 10), It is conceivable that the protrusions 13b and 13b are provided at symmetrical positions from near the protrusion 15 to the lower end (FIG. 11), and the protrusion 13c is provided on the outer wall of the bottom of the tray 14 (FIG. 12). 10 to 12, A is a partially cutaway vertical sectional view, and B is a plan view.

Next, the body 3 may be formed with a curved structure of the sliding portion by a so-called drawing process in which a flat plate like a conventional type is drawn to form a cylindrical body. However, it is desirable to construct the main body 3 from a straight tube that has been subjected to a drawing process as shown in the figure. This is because there is no need to perform drawing work, so the stability of the work is great, and there is no risk of catching the projection of the middle plate body on the part that has been drawn when inserting the middle plate body and damaging it. This is because the overrunning is difficult and the feeding and feeding is further improved. Therefore, the effect of the present invention is remarkable especially when the straight tube is used for the main body 3.

As shown in FIG. 13, the filling 7 and the hakama cylinder 1 may be integrated by forced fitting instead of welding. That is, an annular rib 45 is provided on the outer peripheral surface of the lower part 8 of the inner tool, and the lower part 8 of the inner tool is forcibly fitted to the upper part of the hakama 1 by the annular rib 45. The present invention has a similar effect in such a case, and includes such a case.

Note that FIG. 13 also shows a case where the inner plate body 13 is of a plug-in type, and the upper part is a plate part 14 for containing and holding cosmetics. Reference numeral 14a is a protrusion provided on the dish portion 14 in the vertical direction, and 14b is a small hole provided on the bottom.

Further, regarding fitting of the respective constituent members, an appropriate rotation stopping structure can be provided between the respective members. For example, it is conceivable that each member is engraved in a knurled shape, has a polygonal cross section, is fixed with ribs and slits, or an adhesive.

The cosmetic material contained in the container is optional. In addition to the lipstick as described in the above embodiment, a foundation or the like can be considered. In the case of the foundation, for example, a semi-kneaded product, a powdered product in a solid form, a gelled product, and the like are considered.

The method of accommodating the cosmetics does not matter. It may be a filling type as in the embodiment of FIG. 1 or a plug-in type as shown in FIG. In the former case, even if the cosmetic is filled from the upper opening (a direct filling type), as shown in Fig. 1, a hole is provided at the bottom of the hakama and the cosmetic is filled through the hole ( Bottom filling type) or both.

The diameters of the main body 3, the filling 7, the outer tubular body 9, the inner tray body 13 and other tubular bodies are not limited. The present invention can be applied to either the thick diameter or the small diameter described in the above embodiment.

The material of each component is arbitrary. The members constituting the outside of the container, that is, the hakama 1, the filling 7, and the cap 27 are made of metal, and the inner cap 29 is provided inside the cap 27 in order to maintain the airtightness of the cap portion. If the inner component 7 is fitted to the inner cap 29 as described above, a highly airtight container can be obtained. Further, as described in the embodiment of FIG. 1, the cap 27 is provided with the inner cap 29, but the members constituting the outside of the container, that is, the hull cylinder 1, the inner component 7, and the cap 27 are made of resin. If this is done, the container will have a low airtightness. In this case, as described above, it is also possible to ultrasonically weld the hakama cylinder 1 and the filling 7 to be integrated. Further, the inner cap 29 is omitted, and the filling 7 is directly fitted to the cap 27, and the member constituting the outside of the container, that is, the hakama 1, the filling 7, and the cap 27 are made of resin. For example, in terms of airtightness, it will be an extremely low airtight container that is not much different from ordinary containers. It is also possible that the main body 3 is made of resin. The presence / absence / size of the airtightness of such a container is based on the material of each component, and not on the configuration itself of the present invention.

When used as an airtight container, a protrusion is provided on the inner peripheral surface side of the inner cap 29 when the inner tool 7 and the inner cap 29 are fitted, and the protrusion is provided on the upper outer peripheral surface of the inner tool 7. It is also possible to provide a concave portion corresponding to. However, in the example shown in FIG. 1 described above, the fitting between the inner tool 7 and the inner cap 29 is better.

The position of the welding point between the hakama 1 and the filling 7 is arbitrary.

Furthermore, the various embodiments described above can be combined as appropriate.

Further, as the metal or resin forming each member, an appropriate one can be used other than those described in the above embodiments. For example, as for the inner plate body 13, polypropylene (PP) is often used in the case of the direct filling type and the insertion type, and polybutylene terephthalate (PBT) is used in the case of the bottom filling type.
