Description

  The present invention relates to a cosmetic filling container in which a paste cosmetic is wet-filled.

  Conventionally, as a method of filling cosmetics into a cosmetic filling container such as an inner dish accommodated in a compact container or the like, a product powder of cosmetics such as foundation or red is dissolved in a solvent such as alcohol to form a slurry. There is known a wet filling method (also referred to as a wet direct filling method) in which after a medium dish is filled, the solvent is removed and solidified. In addition, among these wet filling methods, in recent years, the back injection method is often performed. In this back injection method, the upper surface opening of the inner plate is closed with filter paper, and suction means is provided on the filter paper, and in this state, the slurry-like cosmetic is filled with the cosmetic material drilled on the bottom wall of the inner plate. This is a system in which the solvent in the slurry-like cosmetic is sucked and removed by suction means through a filter paper at the same time as being poured into the inner dish at a predetermined pressure from the holes.

As a cosmetic filling container that is wet-filled by such a back injection method, a cosmetic filling container as shown in FIG. 25 has been proposed. In this filling container, the filling container main body 31 is partitioned into a plurality of compartments by partition walls (not shown), and a lower nozzle insertion recess 32 is provided at a substantially central portion of the bottom wall 31a of each of the compartments. And a cosmetic filling hole portion 34 formed of an upper cosmetic injection hole 33 formed with a smaller diameter than the nozzle insertion recess 32 is formed. Then, when filling cosmetic into each compartment, the opening surface of each compartment is closed with the closing plate 35, the tip of the cosmetic injection nozzle 36 is inserted into the nozzle insertion recess 32, and in this state The cosmetic is injected from the cosmetic injection nozzle 36 through the cosmetic filling hole 34 into each compartment (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 1-92911

  However, in the above-mentioned filling container, the cosmetic filling hole 34 is formed upward in the substantially central portion of each section container, and therefore, the cosmetic injected under pressure from the cosmetic injection nozzle 36 into each section container. Flows out directly from the cosmetic injection hole 33 of the cosmetic filling hole 34, collides with the closing plate 35, and then splits to form a plurality of string-like flows on the bottom wall 31a of each section container. Each flowing separately. Therefore, the flow velocity of each string-like flow varies, and due to this difference in flow velocity, the density of the cosmetic ingredients in each string-like flow can be different, and the uneven color and flow pattern of the solidified cosmetic due to this density difference. Arise. Moreover, since the cosmetic flows upward from the cosmetic injection hole 33 at the time of the pressure injection, the cosmetic is strongly compressed between the bottom wall 31a and the closing plate 35 in the upper portion of the cosmetic injection hole 33. In addition, the portion of the closing plate 35 located above the cosmetic injection hole 33 is strongly pressed upward with the cosmetic. As a result, in the upper portion of the cosmetic injection hole 33, the density of the cosmetic component is increased, and unevenness of color occurs in the upper portion of the cosmetic injection hole 33 of the solidified cosmetic, and the surface of the upper portion May adhere to the blocking plate 35 and peel off when the blocking plate 35 is removed.

  The present invention has been made in view of such circumstances, and a cosmetic filling container in which the occurrence of uneven color and flow pattern is alleviated and there is no fear that the surface of the solidified cosmetic is peeled off when the filter paper is removed. The purpose is to provide

In order to achieve the above object, the cosmetic filling container of the present invention has a cosmetic filling recess formed on the upper surface, and a slurry cosmetic filling port is perforated in the bottom wall of the cosmetic filling recess. A cosmetic filling container, wherein the filling port is formed in the vicinity of the peripheral side wall of the cosmetic filling recess, and the slurry flows into at least a part of the inner peripheral surface of the filling port from the inlet of the filling port. The cosmetic is discharged from the outlet of the filling port and directed toward the peripheral side wall adjacent to the charging port, and the slurry-like cosmetic is applied to the peripheral side wall and turned to the opposite side to change the direction. The structure is such that a flow guide is formed.

  That is, in the cosmetic filling container according to the present invention, the slurry-like cosmetic is allowed to flow in from the inlet of the filling port formed in the vicinity of the peripheral side wall of the cosmetic filling recess, and is passed through the filling port. The flow is directed toward the portion of the peripheral side wall close to the filling port by a guide portion provided at the mouth. For this reason, all the slurry-like cosmetic material that has flowed into the filling port immediately flows out from the outlet of the filling port toward the peripheral side wall portion and then hits the peripheral side wall portion, and then changes the direction of the flow. , Flowing in a laminar flow (flow wider in width than the string-like flow) toward the opposite side of the peripheral side wall portion (ie, away from the peripheral side wall portion), Go around the whole. Thus, in the cosmetic filling container according to the present invention, the slurry-like cosmetic that has flowed out from the outlet of the filling port can be applied to the peripheral side wall portion to form a layered flow. Therefore, the variation in the flow rate of the slurry-like cosmetic that flows out from the outlet of the filling port is alleviated, and the occurrence of uneven color and flow patterns due to the difference in density of the cosmetic components is alleviated. In addition, as described above, the slurry-like cosmetic that has flowed out of the outlet of the filling port hits the portion of the peripheral side wall and flows to the opposite side of the portion of the peripheral side wall. The portion of the filter paper corresponding to the outlet of the filling port is not strongly compressed or pressed upward. Therefore, the occurrence of uneven color at the upper part of the outlet of the filling port is alleviated, and there is no possibility that the surface of the solidified cosmetic is peeled off when removing the filter paper. In the present invention, the term “cosmetic filling container” refers not only to a cosmetic dish such as an intermediate dish housed in a cosmetic container recess of a cosmetic container such as a compact container, but also directly into the cosmetic container recess. In the case of wet-filling the material, it refers to the cosmetic container itself.

  Further, in the present invention, when the filling port is formed close to the corner of the peripheral side wall of the cosmetic filling recess, the angle of the corner (two adjacent portions constituting the corner) Therefore, when the slurry-like cosmetic material that flows out from the outlet of the filling port is applied to the corner portion, the slurry-like cosmetic material tends to flow in a laminar flow. In addition, even when the filling port is drilled close to the straight portion of the peripheral side wall of the cosmetic filling recess, when the slurry-like cosmetic that has flowed out from the outlet of the filling port is applied to the straight portion, Here, it is rebounded and flows in a laminar flow on the opposite side of the straight portion or on the side along the straight portion, and spreads over the entire cosmetic filling recess.

  Further, the guide portion is formed of a tapered surface formed on the inner peripheral surface of the filling port from the inlet to the outlet, and the tapered surface is formed on the peripheral side wall of the inlet of the filling port adjacent to the filling port. In the case where it is inclined upwardly from the opposite portion toward the peripheral side wall, the direction of the flow of the slurry-like cosmetic material that has flowed into the filling port from the inlet of the filling port is determined by the taper surface, so that the filling port Can be smoothly directed to the portion of the peripheral side wall adjacent to the surface.

  Further, the guide portion is a stepped portion projecting toward the side of the peripheral side wall in the vicinity of the outlet of the inner peripheral surface of the filling port and on the opposite side of the peripheral side wall close to the filling port. In this case, the shape of the step portion can be appropriately changed, and the degree of freedom in designing the inner peripheral surface shape of the filling port is increased.

  Next, the best mode for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

  1 to 3 show an embodiment of a cosmetic filling container according to the present invention. In this embodiment, an inner dish accommodated in a cosmetic container such as a compact is used as the cosmetic filling container. In these drawings, reference numeral 1 denotes a synthetic resin or metal inner dish in which a slurry-like cosmetic 2 (see FIGS. 10 and 11) is wet-filled. The inner plate 1 includes a bottom wall 11 formed in a substantially rectangular flat plate body and a peripheral side wall 12 of a substantially rectangular frame body standing from the outer peripheral edge of the bottom wall 11. A cosmetic filling recess 13 is formed in a space surrounded by 11 and the peripheral side wall 12. In the figure, reference numeral 12a denotes a portion (one side wall) of the peripheral side wall 12 corresponding to each side of the bottom wall 11.

  In the bottom wall 11, a filling port 14 for filling the slurry-like cosmetic 2 in a state of being close to one of the four corners 11 a is formed in a penetrating manner. . As shown in FIGS. 4 to 7, the filling port 14 rises to a portion on the opposite side of the one corner portion 11 a of the peripheral side surface (inner peripheral surface) of the round hole formed in a circular shape in plan view. An inclined inclined surface 17 is formed.

  More specifically, the filling port 14 has a lower surface opening 15 (a portion opening on the lower surface of the bottom wall 11 serving as an inlet of the slurry-like cosmetic 2) formed in a circular shape, and an upper surface opening 16 ( Of the circular shape formed concentrically and with the same diameter as the lower surface opening 15, the portion that opens to the upper surface of the bottom wall 11 is the opposite of the one corner 11 a. It is formed in a semicircular shape with the half on the side closed. Further, on the peripheral side surface of the filling port 14, a predetermined one point 15a of the lower surface opening 15 [the one corner portion 11a opposite to the one corner portion 11a is opposed to the one corner portion 11a]. Inclined upwardly from the virtual diagonal line 11b (see FIG. 1, FIG. 4 and FIG. 6) connecting to the corner 11a toward the full width of the (semicircular) straight portion 16a of the upper surface opening 16 A tapered surface (guide portion) 17 is formed. The upper surface opening 16 of the filling port 14 is in contact with the outer peripheral edge 11c of the bottom wall 11 at two opposite points 16b (see FIGS. 4 and 6).

  In the above configuration, when the slurry-like cosmetic 2 is wet-filled in the inner dish 1, first, the upper surface opening of the inner dish 1 is closed with the filter paper 4 (see FIG. 8), and suction means (see FIG. In this state, the injection nozzle 5 of the pressurizing injection device (not shown) is positioned at the lower surface opening 15 of the filling port 14 of the inner tray 1, and then the slurry-like cosmetic 2 is placed. It is made to flow upward from the injection nozzle 5 at a predetermined pressure (that is, into the filling port 14) and pressurize and inject into the cosmetic filling recess 13. As a result, the slurry-like cosmetic 2 that has flowed upward from the injection nozzle 5 flows from the lower surface opening 15 of the filling port 14 toward the upper surface opening 16 and is guided by the tapered surface 17 of the filling port 14 during that time. The direction changes diagonally upward (that is, the direction toward the one corner 11a). For this reason, all the slurry-like cosmetics 2 that have passed through the filling port 14 flow out from the upper surface opening 16 of the filling port 14 toward the one corner portion 11a, and are immediately bounced back against this (see FIG. 8). As shown in the arrow), it flows in a laminar flow toward the opposite side of the one corner 11a (that is, the side away from the one corner 11a) (see the arrow in FIG. 9), and the cosmetic filling recess 13 (see FIG. 10 and FIG. 11).

  Thus, in the above-described embodiment, the slurry-like cosmetic 2 that has flowed out of the upper surface opening 16 of the filling port 14 is once applied to the one corner 11a to form a laminar flow. Variations in the flow velocity of the slurry-like cosmetic 2 flowing out from the openings 16 are alleviated, and the occurrence of uneven color and flow patterns due to the density difference of the cosmetic components is alleviated. Moreover, as described above, the slurry-like cosmetic 2 that has flowed out from the upper surface opening 16 of the filling port 14 hits the one corner 11a and flows to the opposite side of the one corner 11a. The upper portion of the upper surface opening 16 of the mouth 14 is filled in a state where it is strongly compressed between the bottom wall 11 of the intermediate dish 1 and the filter paper 4, or the upper side of the upper surface opening 16 of the filling port 14 of the filter paper 4. The portion is not strongly pressed upward. Therefore, the occurrence of color unevenness is mitigated at the upper portion of the upper surface opening 16 of the filling port 14, and there is no possibility that the surface of the solidified cosmetic 2 is peeled off when the filter paper 4 is removed from the upper surface opening of the inner tray 1. Further, the filling port 14 is formed close to the one corner 11a, and the angle of the corner 11a is as narrow as about 90 °, so that the slurry flowed out from the upper surface opening 16 of the filling port 14. When the cosmetic 2 hits the corner 11a, a laminar flow tends to occur. In addition, the slurry-like cosmetic 2 can be smoothly directed toward the corner portion 11a by the tapered surface 17.

  FIG. 12 shows another embodiment of the cosmetic filling container of the present invention. In this embodiment, as shown in FIG. 13, in the above embodiment, one corner portion 11a of the bottom wall 11 is formed in the step portion 21, and the stepped surface 21a of the step portion 21 is inward. It is formed in the inclined surface which inclines in the downward inclination shape. Other parts are the same as those in the above embodiment, and the same reference numerals are given to the same parts. This embodiment also has the same operations and effects as the above embodiment. In addition, in this embodiment, the one corner 11a is formed in the stepped portion 21, and the stepped surface 21a is formed in an inclined surface that goes down toward the inside. Therefore, the one corner 11a rebounds. When the slurry-like cosmetic material 2 flows down from the step portion 21 through the stepped surface 21a onto the bottom wall 11 of the middle plate 1, it flows down vigorously. The fluid flows while spreading in the horizontal direction, and it becomes easy to form a laminar flow.

  14 and 15 show still another embodiment of the cosmetic filling container of the present invention. In this embodiment, in the embodiment shown in FIGS. 1 to 11, the filling port 14 has the one corner portion on the portion on the opposite side of the one corner portion 11 a at the upper part of the peripheral side surface. A stepped portion (guide portion) 22 that protrudes toward the 11a side is formed. More specifically, as shown in FIGS. 16 to 18, the filling port 14 includes a lower hole 23 having a circular shape in plan view that opens on the lower surface of the bottom wall 11, and an upper surface and a lower side of the bottom wall 11. The upper hole 24 having a substantially ¼ arc shape in plan view that opens on the upper surface of the hole 23 (the one corner 11a or a portion outside the one corner 11a is the center of the upper hole 24) A portion of the bottom wall 11 that closes the upper surface opening of the lower hole 23 is formed in the step portion 22. The other parts are the same as those of the embodiment shown in FIGS. 1 to 11, and the same reference numerals are given to the same parts. Also in this embodiment, the same operation and effect as the embodiment shown in FIGS. Moreover, in this embodiment, the shape of the step portion 22 can be changed as appropriate, and the degree of freedom in designing the inner peripheral surface shape of the filling port 14 is increased.

  FIG. 19 shows a main part of still another embodiment of the cosmetic filling container of the present invention. In this embodiment, in the embodiment shown in FIGS. 14 to 18, the filling port 14 includes a lower hole 23 having a circular shape in a plan view that opens on the lower surface of the bottom wall 11, and an upper surface of the bottom wall 11. And an upper hole 24 having a semicircular shape in plan view (see FIG. 20). The upper hole 24 is a circular hole formed concentrically and with the same diameter as the lower hole 23, and is formed as a semicircular hole that closes the opposite half of the one corner 11a. A stepped portion 22 is constituted by the portion thus formed. The other parts are the same as those of the embodiment shown in FIGS. 14 to 18, and the same reference numerals are given to the same parts. Also in this embodiment, the same operation and effect as the embodiment shown in FIGS.

  FIG. 21 shows an essential part of still another embodiment of the cosmetic filling container of the present invention. In this embodiment, in the embodiment shown in FIGS. 14 to 18, the filling port 14 includes a lower hole 23 having a circular shape in a plan view that opens on the lower surface of the bottom wall 11, and an upper surface of the bottom wall 11. And two upper holes 25 each having a circular shape in plan view that open on the upper surface of the lower hole 23 (see FIG. 22), and the portion of the bottom wall 11 that closes the lower hole 23 (that is, the above-mentioned The step portion 22 is constituted by a portion of the bottom wall 11 corresponding to the lower hole 23 excluding the upper holes 25).

  In this embodiment, the slurry-like cosmetic 2 that has flowed into the filling port 14 from the lower surface opening of the lower hole 23 is guided by the step portion 22 and introduced into the upper holes 25, and the upper surfaces of the upper holes 25. Immediately after flowing out from the opening toward the straight portion of the portion 12a (side wall in this embodiment) of the peripheral side wall 12 adjacent to each upper hole 25, it hits each straight portion and forms a laminar flow. It flows toward the opposite side of the portion and the side along each straight portion (see the arrow in FIG. 22), and reaches the entire cosmetic filling recess 13. The other parts are the same as those of the embodiment shown in FIGS. 14 to 18, and the same reference numerals are given to the same parts. Also in this embodiment, the same operation and effect as the embodiment shown in FIGS.

  23 and 24 show still another embodiment of the cosmetic filling container of the present invention. In this embodiment, the bottom wall 11 of the inner tray 1 is brought close to a straight portion of a portion 12a (in this embodiment, one of the four side walls) constituting the peripheral side wall 12. In this state, the filling port 14 is drilled through. The filling port 14 is formed in the same structure as the filling port 14 (see FIGS. 4 to 7) in the embodiment shown in FIGS. The other parts are the same as those of the embodiment shown in FIGS. 1 to 11, and the same reference numerals are given to the same parts. This embodiment also has the same effects as the embodiment shown in FIGS.

  In the above configuration, when the slurry-like cosmetic material 2 is wet-filled in the inner dish 1, the upper opening of the inner dish 1 is formed on the filter paper 4 (see FIG. 8) as in the embodiment shown in FIGS. The injection nozzle 5 of the pressurizing injection device (not shown) is positioned in the lower surface opening 15 of the filling port 14 of the intermediate dish 1 with the suction means (not shown) disposed thereon. After that, the slurry-like cosmetic 2 is discharged from the injection nozzle 5 at a predetermined pressure upward (that is, into the filling port 14) and is injected under pressure into the cosmetic filling recess 13. As a result, the slurry-like cosmetic 2 that has flowed upward from the injection nozzle 5 flows from the lower surface opening 15 of the filling port 14 toward the upper surface opening 16 and is guided by the tapered surface 17 of the filling port 14 during that time. The direction changes diagonally upward (that is, the direction toward the straight line portion). For this reason, all the slurry-like cosmetics 2 that have passed through the filling port 14 flow out from the upper surface opening 16 of the filling port 14 toward the straight line portion, and immediately hit and rebound to form a laminar flow. It flows toward the opposite side of the straight part and the side along the straight part, and reaches the entire cosmetic filling recess 13.

  In the embodiment shown in FIGS. 1 to 11, the tapered surface 17 formed on the peripheral side surface of the filling port 14 is formed from the lower surface opening 15 to the upper surface opening 16. However, the present invention is not limited to this. Instead, it may be formed only on a part of the peripheral side surface of the filling port 14.

  In each of the above embodiments, a part of the filling port 14 is in contact with the outer peripheral edge of the bottom wall 11 of the middle dish 1 (that is, the lower edge of the peripheral side wall 12 of the middle dish 1). 14 may be separated from the outer peripheral edge of the bottom wall 11. In this case, the separation distance between the outer peripheral edge of the bottom wall 11 of the inner tray 1 and the filling port 14 (the portion closest to the outer peripheral edge of the bottom wall 11) is set within a range of 0 to 5 mm.

  Moreover, in the embodiment shown in FIGS. 1 to 11 and FIGS. 23 and 24, the thickness of the bottom wall 11 of the intermediate dish 1 is set within a range of 0.5 to 2.5 mm, and the tapered surface 17 Is set in a range of 10 to 85 °.

  Moreover, in each said embodiment, although the cosmetic filling recessed part 13 of the inner tray 1 is formed in square shape, you may form in triangle shape. In this case, when the filling port 14 is formed in one of the three corners 11 of the bottom wall 11 of the cosmetic filling recess 13, the one corner 11 a is formed from the upper surface opening 16 of the filling port 14. The slurry-like cosmetic 2 that has flowed out toward the surface and then bounced back is easily spread over the entire cosmetic filling recess 13 in a layered flow. Further, the cosmetic filling recess 13 of the inner dish 1 may be formed in an elongated shape so as to be bent in a straight line or a wave shape. Also in this case, the filling port 14 is formed in the corner 11a of the bottom wall 11 of the cosmetic filling recess 13 (for example, one end of the cosmetic filling recess 13), thereby forming a laminar flow. The effect that it becomes easy to spread over the whole material filling recessed part 13 is produced.
