  However, the storage part of the container for viscous cosmetics of Patent Documents 1 and 2 has a coating wall formed separately from the storage part as described above, and is assembled to the filling port of the viscous cosmetics. Unevenness occurred at the boundary between the part and the coating wall, and the appearance was poor. In addition, in such a container for viscous cosmetics, since the viscous cosmetics cannot be filled up to the application wall and a space is created near the application wall, when the storage part and the application wall are formed of a transparent material, The appearance when the inside of the storage portion is seen through is also poor. Moreover, since it is necessary to manufacture a storage part and an application | coating wall separately, manufacture became complicated, such as the number of parts increasing and the effort which attaches parts.

Therefore, it is considered that the storage portion and the application wall are integrally formed without forming the storage portion and the application wall separately, but in that case, the opening portion side opposite to the application wall side of the storage portion is considered. Therefore, the container is filled with the viscous cosmetic material, and then the inside dish is inserted. However, insertion of inner plate in close contact with the inner periphery of the housing part in the housing section, to become shall inevitably intervening air between the viscous cosmetic material and inner tray, in which close contact with the inner periphery of the housing part When the dish is inserted into the storage part, the storage part is hermetically sealed by the intermediate dish, and the viscous cosmetic is pressed through the air interposed between the viscous cosmetic and the intermediate dish.

  For this reason, when the intermediate dish is inserted into the storage unit, the internal pressure rises and the viscous cosmetic material may be discharged from the distribution port of the application wall. In addition, when the viscous cosmetic is stored and stored with air interposed and kept airtight as described above, the volume of air interposed in the storage portion expands due to a change in the outside air temperature, and the internal pressure in the storage portion is increased. As a result, the viscous cosmetic material in the storage unit may leak to the outside through the distribution port.

Therefore, the present invention is intended to solve the above-described problems, and the storage portion and the application portion are integrally formed so that the surface is smooth without unevenness, and the storage portion is easily manufactured. However, it is intended to make the viscous cosmetic material fillable without creating a space to the application wall. In addition, in the storage unit, after the start of use, the viscous cosmetic and the inner plate are brought into close contact with each other without air, so that the viscous cosmetic can be smoothly pressed and discharged from the distribution port by the movement of the inner plate. It is something to try.

  One end is an opening and the other end is an application wall provided with a distribution port for viscous cosmetics. The distribution port of the application wall is closed with a seal member so that it can be opened, and the inner peripheral surface on the opening side is for air venting. In the cylindrical storage part provided with a concave groove, the filling process of filling the viscous cosmetic from the opening within the range not reaching the concave groove, and the inner part of the storage part are in close contact with the storage part that has been filled And the step of inserting the intermediate dish from the opening while removing the air interposed between the intermediate dish and the viscous cosmetic from the groove.

  In addition, one end is an opening and the other end is an application wall provided with a distribution port for viscous cosmetics, and the distribution port of the application wall is closed with a seal member so as to be openable, and on the inner peripheral surface on the opening side. Stored in a cylindrical storage section provided with a concave groove for venting air, a viscous cosmetic filling from the opening within the storage section to the extent that the concave groove is not reached, and a storage section that has been filled with the viscous cosmetic. It consists of an inner dish that is in close contact with the inner periphery of the section and is inserted from the opening while excluding air intervening with the viscous cosmetic material from the groove.

Further, the storage unit may be partially or entirely made of a translucent or transparent material so that the viscous cosmetic material stored in the storage unit can be seen through.

  Further, the inner tray may have a tip shape corresponding to the shape of the inner surface of the tip wall of the storage unit.

  Further, the inner dish may be one in which a sealing member is provided on the base opposite to the side in contact with the viscous cosmetic.

  In addition, in the storage part formed by inclining the application wall in the axial direction, an inner dish having an inclined extrusion surface on the viscous cosmetic side corresponding to the application wall is mounted so as to be rotatable in the circumferential direction. A tapered engaging step portion is provided on the outer peripheral surface of the plate, and a step receiving portion that can be engaged with the tapered engaging step portion of the inner plate is provided on the inner peripheral surface of the storage portion. When the inner surface is in contact with the extrusion surface of the intermediate tray, the engagement step portion of the intermediate tray and the step receiving portion of the storage portion may be in surface contact.

In the present invention, an opening is formed at one end of the storage portion, an application wall provided with a viscous cosmetic dispensing port is formed at the other end, and this application wall is formed integrally with the storage portion. with the production parts can be made easy, even for bets to Rukoto smooth without irregularities to the surface of the housing part it is possible.

  In addition, the distribution port of the application wall of the storage part is closed so that it can be opened, and the viscous cosmetic is filled from the opening side opposite to the application wall to the extent that it does not reach the concave groove of the storage part. It becomes possible to fill the viscous cosmetic without generating a space. In addition, after filling the viscous cosmetic in this manner, when the inner tray that is in close contact with the inner periphery of the storage portion is mounted in the storage portion and the intermediate tray is moved toward the coating wall, It is possible to exclude the air intervening between and the outside through a concave groove formed in the inner peripheral surface of the storage portion.

  Accordingly, the inner dish can be adhered to the viscous cosmetic material without interposing an air layer, and after the adhesion, the communication between the concave groove and the viscous cosmetic material is blocked by the inner dish, and the airtightness in the storage portion is maintained. It is possible to press the viscous cosmetic material in the direction of the coating wall and discharge the viscous cosmetic material to the outside from the distribution port. Therefore, after the start of use, the viscous cosmetics are brought into close contact with the inner dish without any air in the storage unit, and the viscous cosmetics can be smoothly pressed and discharged from the dispensing port by the movement of the inner dish. It is supposed to be.

  The first embodiment of the present invention will be described with reference to FIGS. 1 to 5. (1) is a storage portion, an opening (2) is formed at the base end, and an elliptical flat shape is formed at the tip. The coating wall (3) formed in is provided. The application wall (3) is inclined so as to intersect the axial direction of the storage portion (1). Therefore, by supporting the viscous cosmetic container with the application wall (3) side facing upward, the entire surface of the application wall (3) can be easily brought into contact with the application surface such as lips for application purposes. Is possible.

  In addition, a plurality of distribution ports (4) having a diameter of 1 mm are formed in the application wall (3) in the axial direction of the storage part (1), and the viscous cosmetic (5) stored in the storage part (1) is provided. By pressing with the inner tray (6), it can be discharged outward from the distribution port (4). Moreover, as shown in FIG.1 and FIG.2, the inner peripheral surface (12) by the side of the opening part (2) of a storage part (1) is provided with the groove | channel (7) for air venting, and an opening part (2) at one end. One end is formed in the axial direction so as to reach the opening edge (8), and the other end of the concave groove (7) is made up to the planned filling surface of the viscous cosmetic (5).

  The storage part (1) is made of an opaque material so that the viscous cosmetic material (5) stored in the storage part (1) is not affected by external light. For this reason, it is possible to prevent deterioration in quality such as alteration and deterioration of the viscous cosmetic material (5) due to external light.

  Further, as shown in FIG. 1, the seal member (10) is detachably secured to the surface of the application wall (3) of the storage part (1), and a distribution port (4) provided in the application wall (3) is provided. Closed. By fixing the sealing member (10) in this way, the viscous cosmetic (5) leaks out from the distribution port (4) when the cosmetic (5) is filled into the storage part (1). To prevent it. Then, as shown in FIG. 4, when the seal member (10) is removed from the application wall (3) at the start of use, the viscous cosmetic material (5) in the storage portion (1) is transferred from the distribution port (4) to the outside. It becomes possible to discharge.

  Further, as shown in FIG. 1, an inner dish (6) for pressing the viscous cosmetic (5) in the direction of the application wall (3) is disposed in the storage part (1). The inner plate (6) is formed in a columnar shape, and the outer peripheral surface (11) of the storage portion (1) is kept airtight in the storage portion (1) when mounted on the storage portion (1). It is configured to be slidable in the axial direction within the storage portion (1) while being in close contact with the inner peripheral surface (12). Moreover, the inner tray (6) is connected to a cylindrical feeding rod (13) having an outer peripheral thread groove formed on the side opposite to the viscous cosmetic (5) so as to be rotatable. Moreover, this feeding rod (13) has an insertion hole (14) opened in the axial direction at one end opposite to the side of the inner tray (6) to the vicinity of the inner tray (6). A key groove (15) is provided in the axial direction on the inner periphery of the insertion hole (14).

  Further, as shown in FIG. 3, a cylindrical holding portion (16) having an H-shaped cross section for holding by hand during use is connected and fixed to the outer peripheral surface on the opening (2) side of the storage portion (1). ing. The holding portion (16) is divided into upper and lower portions by providing a partition wall (17) in the center, and the partition wall (17) has a bottom surface (18) on the storage portion (1) side that has an opening edge of the storage portion (1) ( 8) is fixedly arranged at a position where it abuts. A through hole (19) having an inner circumferential groove is provided in the center of the partition wall (17), and a feed bar (13) is threaded through the through hole (19) to feed the feed bar (13). 13) is assembled to the holding part (16).

Further, as shown in FIG. 1, a cylindrical rotating body (20) is rotatably connected to the side of the holding portion (16) opposite to the storage portion (1) side. The rotating body (20) has an inner diameter that is substantially the same as the inner diameter of the holding section (16), opens one end on the holding section (16) side, and is provided with a bottom wall (21) at the other end. Further, an engaging protrusion (22) is provided in the circumferential direction on the outer periphery of the rotating body (20), and the engaging protrusion (22) is recessed in the inner peripheral surface of the holding part (16). The recess (23) is engaged.

  In addition, an engagement shaft (24) is formed to project in the axial direction at the center of the inner surface of the bottom wall (21) of the rotating body (20). The engagement shaft (24) has an engagement groove (25) formed on the outer periphery, and the engagement groove (25) is provided in a key groove (14) provided in the insertion hole (14) of the feeding bar (13). 15) The engaging rod (13) cannot be rotated in the circumferential direction with respect to the engaging shaft (24) by inserting the engaging shaft (24) into the insertion hole (14) while being engaged with the engaging shaft (15). However, it is slidably assembled in the axial direction. Therefore, by assembling as described above, the rotating body (20) can be rotatably connected to the holding portion (16) via the feeding bar (13).

  In the configuration as described above, as shown in FIG. 5, the distribution port (4) provided in the application wall (3) of the storage portion (1) is closed by the seal member (10), and the application wall (3) side is closed. The viscous cosmetic material (5) is filled from the opening (2) with the face down. In this embodiment, as shown in FIG. 1, the filling amount of the viscous cosmetic material (5) is the concave groove provided on the inner peripheral surface (12) of the storage portion (1) by the upper surface (26) of the viscous cosmetic material (5). The amount coincides with the lower end (27) of (7). The upper surface of the viscous cosmetic material (5) filled in the storage part (1) does not coincide with the lower end (27) of the concave groove (7) due to an error during manufacture, and the lower end (27 of the concave groove (7) ) Slightly closer to the coating wall (3) side, there is no problem even if some air enters the storage portion (1). In this embodiment, lip gloss is used as the viscous cosmetic (5).

  Then, the feeding bar (13) is threaded through the partition wall (17) of the holding part (16), so that the feeding bar (13) connected to the inner tray (6) is assembled to the holding part (16), and the viscous makeup is applied. The inner pan (6) is inserted into the opening (2) side in the storage portion (1) filled with the material (5), and the bottom surface (17) of the partition wall (17) is inserted into the opening edge (8) of the storage portion (1). 18), the inner peripheral surface of the holding portion (16) is fixed to the outer peripheral surface of the storage portion (1). Finally, the engaging shaft (24) of the rotating body (20) is inserted into the insertion hole (14) of the feeding bar (13), and the rotating body (20) is assembled to the holding portion (16).

  In the assembly as described above, by rotating the rotating body (20) in one direction, the engaging shaft (24) formed to protrude from the rotating body (20) rotates in the same direction. Accordingly, since the feeding bar (13) engaged with the engaging shaft (24) rotates, the feeding bar (13) is moved by the inner peripheral thread groove of the through hole (19) of the holding portion (16). It is sent out in the direction of the coating wall (3).

  At this time, since the engaging protrusion (22) of the rotating body (20) is engaged with the engaging recess (23) of the holding part (16), the rotating body (20) rotates in the circumferential direction. It is impossible to move in the direction of the coating wall (3). On the other hand, the feeding rod (13) engaged with the engaging shaft (24) of the rotating body (20) is slidable in the axial direction with respect to the engaging shaft (24). Independent of (20), it is smoothly fed out in the direction of the coating wall (3). And with this movement of the feeding bar (13), the inner tray (6) connected to the feeding bar (13) brings the outer peripheral surface (11) into close contact with the inner peripheral surface (12) of the storage part (1). While moving in the direction of the coating wall (3).

  Here, when the inner tray (6) is mounted in the storage section (1), air is present between the extrusion surface (28) of the inner tray (6) and the upper surface (26) of the viscous cosmetic (5). Although the layer is interposed, by moving the inner tray (6) in the direction of the coating wall (3), as shown in FIG. 3, this air layer is formed in the storage portion (1) located on the side surface of the inner tray (6). It passes through the concave groove (7) and is removed to the holding part (16) side than the inner dish (6). In this way, while removing the air layer interposed between the intermediate dish (6) and the viscous cosmetic (5) on the holding part (16) side, the intermediate dish (6) is further directed toward the coating wall (3). By moving, as shown in FIG. 4, it becomes possible to make the extrusion surface (28) of the inner tray (6) adhere to the upper surface (26) of the viscous cosmetic (5) without interposing an air layer.

Then, as shown in FIG. 4, at the start of use, the application wall (3) is filled with the viscous cosmetic (5).
The sealing member (10) that has been fixed to the surface is removed, and the viscous cosmetic material (5) can be discharged from the distribution port (4) of the application wall (3) to the outside. Then, the inner plate (6) is further moved in a state where the extrusion surface (28) of the inner plate (6) and the upper surface (26) of the viscous cosmetic material (5) are brought into close contact with each other, thereby moving the inner portion (1) The viscous cosmetic material (5) can be discharged from the distribution port (4) to the outside.

  At this time, the viscous cosmetic (5) is arranged so that the lower end (27) of the concave groove (7) for air discharge and the upper surface (26) of the viscous cosmetic (5) are in the same position in the storage part (1). When the extrusion surface (28) of the inner plate (6) and the upper surface (26) of the viscous cosmetic material (5) are in close contact with each other, the outer peripheral surface (11) of the inner plate (6) is concave. It separates from the groove (7) and comes into close contact with the inner peripheral surface (12) of the storage part (1). Therefore, in such a state, since the viscous cosmetic (5) can be held in the storage portion (1) in an airtight state, the viscous cosmetic (5) is brought into contact with air after the start of use. It becomes possible to prevent deterioration of quality such as deterioration and alteration.

  A second embodiment of the present invention is shown in FIG. In the first embodiment, as shown in FIG. 1, the inner shape of the coating wall (3) is provided so as to be inclined with respect to the forming axis of the storage portion (1), and the inner tray mounted in the storage portion (1). (6) is formed in a circular shape so that the pushing surface (28) on the front end side of the inner tray (6) is perpendicular to the forming axis of the storage portion (1). Therefore, since the inner surface shape of the application wall (3) and the tip shape of the intermediate dish (6) are different, the entire extrusion surface (28) of the intermediate dish (6) contacts the inner surface (30) of the application wall (3). It becomes impossible to make it. Therefore, in 1st Example, the whole quantity of the viscous cosmetics (5) with which the storage part (1) was filled cannot be discharged outside from a distribution port (4), and a viscous cosmetic (5) is stored in a storage part ( 1) It remains in the inside and becomes uneconomical.

  Therefore, in the second embodiment of the present invention, as shown in FIG. 6, the tip shape of the inner tray (6) is made to correspond to the shape of the inner surface (30) of the application wall (3) of the storage portion (1). Thus, the entire extrusion surface (28) is formed at the tip by forming the extrusion surface (28) of the inner tray (6) at an inclination angle similar to the inclination angle of the inner surface (30) of the coating wall (3). It can be brought into contact with the inner surface (30) of the wall (3). In addition, a sealing member (31) made of soft polyethylene or hard polyethylene is provided at the base portion on the opposite side of the extrusion surface (28) of the inner tray (6) in order to improve airtightness.

  The sealing member (31) is formed so that the outer periphery (34) is in close contact with the inner peripheral surface (12) of the storage portion (1) when the inner tray (6) is mounted in the storage portion (1). Yes. Further, the inner tray (6) provided with the sealing member (31) in this manner is rotatably connected to the feeding bar (13) as in the first embodiment.

  As described above, since the tip shape of the inner tray (6) corresponds to the inner surface shape of the application wall (3), the entire extrusion surface (28) of the inner tray (6) is the inner surface of the application wall (3) ( It is necessary to perform positioning so as to make contact with 30) smoothly and reliably. Therefore, as shown in FIG. 6, a tapered engaging step portion (32) is formed on the outer peripheral surface (11) of the inner plate (6) so as to be engaged with the engaging step portion (32). A possible step receiving portion (33) is formed to protrude from the inner peripheral surface (12) of the storage portion (1).

  Then, when the extrusion surface (28) of the inner tray (6) and the inner surface (30) of the coating wall (3) are brought into contact with each other, the engagement step portion (32) and the step receiving portion (33) are in surface contact. The dimensions are possible. The inner tray (6) provided with the engagement step (32) has an outer diameter on the base side with respect to the engagement step (32), which is slightly smaller than the outer diameter of the sealing member (31). In addition to being formed in a cylindrical shape, the outer diameter on the tip side of the engaging step portion (32) is formed in a cylindrical shape having a slightly smaller diameter than the outer diameter on the base side.

  In the case where such alignment means is provided, when the inner tray (6) is mounted in the storage portion (1), the application wall (3) of the storage portion (1) and the inner tray (6) are misaligned. A mechanism for correcting the position of the inner dish (6) when the wake has occurred is described. First, when the rotating body (20) is rotated to move the middle dish (6) in the direction of the coating wall (3), the middle dish (6) is engaged in the final stage of use of the viscous cosmetic (5). The step portion (32) abuts against the step receiving portion (33) of the storage portion (1).

  Since the step receiving portion (33) and the engagement step portion (32) are formed in a tapered shape, the inner plate (6) is applied to the coating wall (3) by further rotation of the rotating body (20). And moves in the circumferential direction along the tapered surface of the step receiving portion (33). By this rotation, the position of the inner tray (6) is gradually corrected corresponding to the shape of the coating wall (3), and finally the engagement step portion (32) and the step receiving portion (33) are completely engaged. As a result, the extrusion surface (28) of the inner tray (6) and the inner surface (30) of the coating wall (3) can be brought into contact smoothly and reliably.

  Moreover, when the inner tray (6) provided with the sealing member (31) is mounted in the storage portion (1) filled with the viscous cosmetic (5), the sealing member (31) and the viscous cosmetic (5) An air layer is interposed between them. When the inner tray (6) is moved in the direction of the application wall (3), an air layer interposed between the sealing member (31) and the upper surface (26) of the viscous cosmetic (5) as shown in FIG. However, the sealing member (through the gap between the outer peripheral surface (11) of the inner tray (6) and the inner peripheral surface (12) of the storage portion (1) and the concave groove (7) positioned on the side surface of the sealing member (31). 31) is excluded to the holding part (16) side.

  Further, since the middle dish (6) of the present embodiment has an elongated shape in the axial direction, when the middle dish (6) is mounted in the storage portion (1), the tip of the middle dish (6) The side enters into the filling area of the viscous cosmetic (5). Therefore, the upper surface (26) of the viscous cosmetic material (5) in the storage part (1) moves to the storage part (1) as the inner tray (6) moves toward the application wall (3) in the storage part (1). It moves in the direction of the opening (2) of 1) and enters the gap between the inner peripheral surface (12) of the storage portion (1) and the outer peripheral surface (11) of the inner tray (6).

  Therefore, in this embodiment, unlike the first embodiment, the filling amount of the viscous cosmetic material (5) in the storage section (1) is set to the connecting surface (35) on the inner tray (6) side of the sealing member (31). ) Reaches the lower end (27) of the concave groove (7) and at the same time, the upper surface (26) of the viscous cosmetic (5) in the storage part (1) reaches the lower end (27) of the concave groove (7). It is adjusted. Therefore, after the sealing member (31) is moved to the lower end (27) of the groove (7), the connection surface (35) of the sealing member (31) is made viscous by further moving in the direction of the coating wall (3). In close contact with the upper surface (26) of the cosmetic (5), the outer periphery (34) of the sealing member (31) is separated from the concave groove (7), and is in close contact with the inner peripheral surface (12) of the storage portion (1). Therefore, it becomes possible to hold the viscous cosmetic material (5) in the storage portion (1) in an airtight state. In the present embodiment, as in the first embodiment, the upper surface of the viscous cosmetic material (5) filled in the storage portion (1) is formed at the lower end of the concave groove (7) due to an error during manufacture. 27), and it is located slightly closer to the application wall (3) than the lower end (27) of the concave groove (7), so there is no problem even if some air enters the storage part (1). .

  In the first embodiment, the storage portion (1) is made of an opaque material and is not affected by external light. In the second embodiment of the present invention, the storage portion (1) is provided. It is possible to make the inside of the storage part (1) transparent by forming it with a transparent material, and to easily check the remaining amount of the viscous cosmetic (5) in the storage part (1) after use. It is possible.

Therefore, since the user can check the remaining amount of the viscous cosmetic (5) in the storage unit (1), it is possible to prevent inconveniences such as sudden disappearance of the viscous cosmetic (5) during use. It becomes possible. Further, when the extruded surface (28) of the inner tray (6) comes into contact with the inner surface (30) of the application wall (3), the user can remove the viscous cosmetic (5) stored in the storage unit (1). It can be confirmed that the entire amount has been used up, and the satisfaction of completing the economical use can be obtained. Since forming housing portion (1) in transparent material in the present embodiment, when not in use accommodating portion an opaque lid capable of covering the housing portion (1) whole (1) and the like provided, it is preferable to reduce the influence of external light.

  In the present invention, since the coating wall (3) is formed integrally with the storage portion (1), not only the outer peripheral surface of the storage portion (1) but also the inner peripheral surface (12) are smooth and have no irregularities. It has become. Therefore, by forming the storage part (1) with a transparent material, the appearance when the inside of the storage part (1) is seen through is also beautiful.
