Description

  The present invention relates to a feeding container that accommodates a rod-shaped solid material as a content so as to be able to be fed and fed, and particularly in such a feeding container, by quickly discharging bubbles generated when filling the content. The present invention relates to a degassing mechanism for a feeding container for preventing voids due to bubbles from occurring in the content after cooling and solidification, and causing the content to become brittle.

  As a container for stick-shaped cosmetics (lipsticks, etc.), a container called a feeding container has been hitherto known that allows the stick-shaped cosmetics to be fed and unloaded by relatively rotating the container exterior and the stick-shaped cosmetic holder. Moreover, in such a feeding container, the bubbles generated when the contents are filled are quickly discharged, so that the voids (called “po”) are formed in the contents after cooling and solidification. In order to prevent the occurrence of such a problem, a structure has been conventionally known from Patent Document 1 below.

That is, in the following Patent Document 1, a linear cylindrical outer cylinder having an inner peripheral surface engraved with a thread groove, a storage cylinder portion whose upper half is a cosmetic mold surface, and a lower half which is a vertically long guide. An inner cylindrical body serving as a guide cylinder having a hole, and a holding projecting piece for holding cosmetics by projecting on the outer peripheral surface a threaded projecting piece that passes through the guide hole of the inner cylindrical body and is screwed into a thread groove of the outer cylindrical body The cylindrical body is provided with a linear cylindrical saucer body provided on the inner peripheral surface, and a cap-shaped cylindrical body that opens and closes the upper end opening of the storage cylinder portion of the inner cylinder body, and the outer cylinder body and the inner cylinder body include A bottom-filling type feeding container is described in which it is pivotably assembled so that it cannot be pulled out, and a tray body is assembled inside the inner cylinder so as to be movable up and down.
JP-A-8-238125

  By the way, in the conventionally known bottom-filling type feeding container as described above, when the cosmetic is filled and cooled and solidified, the tray body is positioned at the lower limit inside the inner cylinder, and the inner cylinder The upper end opening of the storage cylinder is sealed by fitting a dedicated mold cap to form a cosmetic molding space in the container body, and then the melted makeup in a state where the container body is in an inverted position. After injecting and filling the material into the molding space from the lower end side of the saucer body, the cosmetic body is cooled and solidified by cooling the entire container body, and the cosmetic material thus cooled and solidified is contained in the saucer body. It is held by holding protrusions formed on the peripheral surface.

  In such a feeding container, when the molten cosmetic is poured and filled into the molding space from the bottom side of the container body with the container body in an inverted position, voids due to bubbles are generated. A gap is formed at the lower edge of the saucer body so that the cosmetic material having a uniform density distribution can be solidified without causing the melted cosmetic material to be blocked between the storage cylinder part of the inner cylinder body and the saucer body. However, it forms a clearance to let air through.

  However, in such a feeding container as described above, the cooled and solidified cosmetic is held only by the holding protrusions formed on the inner peripheral surface of the tray body. In the case of use, there is a risk that the cosmetic may come off from the tray body and come out of the storage cylinder of the inner cylinder during use. During filling, air bubbles accumulate in the corners, which are the connection between the inner peripheral surface of the saucer and the holding projection, and voids are generated at the base of the stick-shaped cosmetic when the cosmetic is cooled and solidified. There is a risk that the cosmetic material may fall off from the root when the portion becomes brittle and breaks during use.

  An object of the present invention is to eliminate the above-described problems. Specifically, for a feeding container in which a molten content is filled from the bottom side of the container body, bubbles are contained in the solidified content. It is an object of the present invention to ensure that the solidified contents can be reliably held without generating voids due to.

In order to solve the above-described problems, the present invention has a pin projecting on the outer peripheral surface of a cylindrical receiving cylinder that holds a rod-shaped content, and the pin of the receiving cylinder passes through the outer side of the receiving cylinder. A guide tube having a guide hole formed at the bottom is provided, a screw tube having a screw groove formed on the inner peripheral surface for receiving a pin of the receiving tube is provided outside the lower portion of the guide tube, and an exterior body is provided outside the screw tube.

As a result, it is possible to prevent the generation of voids due to bubbles in the content after cooling and solidification. In addition, while the projection for fixing the contents is formed in the vicinity of the filling port of the pedestal portion, the vent hole for venting is connected between the circumferential center of the projection and the center of the pedestal portion. Since it is formed at a position shifted in the circumferential direction from the straight line, when holding the rod-shaped contents by the flat plate-like pedestal, the holding effect of the contents by the protrusion and the vent hole for venting gas Due to the holding effect of the content by solidifying the overflowing content, a sufficient holding force can be applied over the entire circumference of the pedestal portion, and the content can be reliably held.

For a feeding container that fills the melted contents from the bottom side of the container body, the object is to ensure that the solidified contents can be held without generating voids due to bubbles in the solidified contents. As specifically shown in the following embodiment as the best mode, a pin protrudes from the outer peripheral surface of a cylindrical receiving cylinder holding the rod-shaped contents, and the pin of the receiving cylinder is provided outside the receiving cylinder.

The upper cylindrical portion 41 and the intermediate cylindrical portion 42 have substantially the same inner diameter, but the inner diameter of the lower cylindrical portion 43 is larger than those, while the lower cylindrical portion 43 extends downward from the cylindrical portion 42. The outer cylindrical portion 42 and the lower cylindrical portion 43 have substantially the same outer diameter, but the upper cylindrical portion 41 has a smaller outer diameter than that, and the thickness of the intermediate cylindrical portion 42 is It is thicker than the thickness of the upper cylinder part 41 and the lower cylinder part 43.

  A circumferential protrusion 44 is formed on the guide cylinder 4 so as to protrude outward from the outer peripheral surface of the intermediate cylindrical portion 42, and a convex portion 44 a for a stopper is formed on the outer peripheral surface of the peripheral protrusion 44. As shown in FIG. 7 and FIG. 8, the convex portion 44a is inwardly formed at the portion of the circumferential ridge 44 located inward of the convex portion 44a. A gap 44b is formed to be elastically displaceable. In addition, the guide tube 4 has a lower tube portion in which a guide hole 45 for allowing the pin 33 of the receiving tube 3 to pass through is continuous from the lower end of the guide tube 4 to the vicinity of the lower portion of the circumferential protrusion 44. 43 is formed at two positions symmetrically.

  As shown in FIG. 6, the screw cylinder 5 provided outside the lower part of the guide cylinder 4 is formed with two thread grooves 51 for receiving the two pins 33 of the receiving cylinder 3 on the inner peripheral surface thereof. In addition, although not shown in the drawing on the outer peripheral surface thereof, the outer peripheral body 6 is engaged with the locking protrusion on the inner peripheral surface so as to be immovable in the circumferential direction. A number of knurled grooves extending in the vertical direction (the container axis direction) are formed.

On the inner peripheral surface of the body portion 61 of the exterior body 6, although not shown in the drawing, locking protrusions that engage with the knurled grooves on the outer peripheral surface of the screw cylinder 5 are formed at six locations. An opening 63 for filling the contents is opened at the center of the bottom 62 of the exterior body 6. The opening 63 is sealed with a sheet lid mainly composed of an aluminum foil after filling the contents.

  The sealing cylinder 7 provided at the upper end of the exterior body 6 is fixed to the upper end of the body 61 of the exterior body 6 by ultrasonic welding or the like, and as shown in FIG. Then, the upper cylinder part 71 is connected in a state of being displaced upward and inward from the upper end of the lower cylinder part 72, and the upper end surface of the exterior body 6 is projected outward from the outer peripheral surface of the lower cylinder part 72. An annular convex portion 73 welded to the upper cylindrical portion 71 is formed on the outer peripheral surface of the upper cylindrical portion 71, and a screw portion (male screw) 74 is formed on the outer peripheral surface of the lower cylindrical portion 72. An annular groove 75 is formed. The annular groove 75 locks a protrusion 84 formed below the threaded portion 83 of the cap 8 in order to prevent the cap 8 from loosening when the container is not used.

  Further, the sealing cylinder 7 is integrally provided with a sealing ring 76 having an inner peripheral surface protruding inward from the inner peripheral surface of the upper cylinder portion 71 so as to extend downward from the inner peripheral surface side of the upper cylinder portion 71. Is formed. The outer peripheral surface of the sealing ring 76 is separated from the inner peripheral surface of the lower cylinder portion 72, and is between the sealing ring 76 and the lower cylinder portion 72 (the portion of the sealing cylinder 7 located outside the sealing ring 76). A gap portion 77 is formed in the seal ring 76 so that the seal ring 76 can be easily elastically deformed outward in the radial direction of the container.

  The inner peripheral surface of the sealing ring 76 is formed so as to be in close contact with the substantially vertical cylindrical outer peripheral surface of the intermediate cylinder portion 42 of the guide cylinder 4 above the peripheral protrusion 44 of the guide cylinder 4. The intimate part of the guide cylinder 4 and the sealing ring 76 is located in the vicinity of the back side of the annular groove 75 of the sealing cylinder 7 through a gap 77 between the sealing ring 76 and the lower cylinder part 72. This close portion is located in a range where the sealing cylinder 7 and the cap 8 overlap each other when viewed in the container axial direction (vertical direction).

A large number of small intervals are formed in the direction, and a stopper convex portion 44 a formed on the outer peripheral surface of the peripheral protrusion 44 of the guide tube 4 is engaged with any one of the many concave portions 78 of the sealing tube. Thus, when the guide tube 44 is rotated relative to the sealing tube 7 (and the exterior body 6), the convex portion 44a of the guide tube 4 touches the concave portion 78 of the sealing tube 7 with a predetermined resistance (click). Feeling).

  That is, the concave portion 78 of the lower cylindrical portion 72 of the sealing cylinder 7 and the convex portion 44a of the circumferential protrusion 44 of the guide cylinder 4 relatively rotate the guide cylinder 4 and the exterior body 6 by applying a predetermined rotational torque. Each of the click mechanisms when used is a stopper. Since this click mechanism also functions as a stopper mechanism between the guide cylinder 4 and the sealing cylinder 7, the guide cylinder 4 is prevented from rotating carelessly with respect to the exterior body 6 to which the sealing cylinder 7 is fixed. It can be surely prevented.

  In the present embodiment, the engaging recess 78 extends in the vertical direction (in the container axis direction) from the upper part to the lower end of the inner peripheral surface of the lower cylinder part 72 of the sealing cylinder 7. Even if the guide cylinder 4 having the mating convex portion 44a is slightly displaced in the vertical direction (container axis direction), the engagement of the engaging convex portion 44a and the engaging concave portion 44b can be maintained.

  In the cap 8 engaged with the sealing cylinder 7 of the container body 2, as shown in FIG. 1, a skirt portion 82 is suspended from the peripheral edge portion of the disk-shaped top plate portion 81. A protrusion 85 for positioning the seal member 9 is formed on the outer peripheral portion of the inner surface (lower surface) at a position slightly away from the inner peripheral surface of the skirt portion 82. Further, as shown in FIG. 7, a screw portion (female screw) 83 that is screwed with a screw portion (male screw) 74 of the sealing cylinder 7 is formed on the inner peripheral surface of the lower portion of the skirt portion 82. Below 83, the latching protrusion 84 latched by the annular groove 75 of the sealing cylinder 7 is formed in four places at equal intervals in the circumferential direction.

  In the sealing member 9 attached to the cap 8, a cylindrical peripheral wall upper part 92 extends downward from the peripheral part of the disk part 91, and extends downward from the lower end of the peripheral wall upper part 92 isolated inward from the skirt part 82 of the cap 8. A tapered peripheral wall lower portion 93 extends outward, and an annular protrusion 94 is formed on the inner peripheral surface of the lower end portion of the cylindrical peripheral wall upper portion 92 so as to be in close contact with the outer peripheral surface near the upper end of the guide tube 4. The lower end of the tapered peripheral wall lower portion 93 is in contact with the inner peripheral surface of the skirt portion 82 of the cap 8. Note that the portion where the annular protrusion 94 of the seal member 9 is in close contact with the outer peripheral surface of the guide tube 4 is in a range 2 to 7 mm below the upper end of the guide tube 4.

  The cap 8 and the seal member 9 are fixed by a hot melt adhesive or the like. Specifically, a plurality of semicircular ribs are formed concentrically on the outer surface (upper surface) of the disc portion 91 of the seal member 9 in plan view, and the inner surface (lower surface) of the top plate portion 81 of the cap 8. ) Is applied to the vicinity of the center portion of the sealing member 9 and the disc portion 91 of the sealing member 9 is attached to the inner periphery of the positioning projection 85 so that the outer periphery of the disc portion 91 of the sealing member 9 is fitted into the cap 8. By pressing against the top plate portion 81, the hot melt adhesive flows through the gap between the semicircular ribs of the disc portion 91 of the seal member 9, and the cap 8 and the seal member 9 are firmly bonded. Become.

  The usage state of the feeding container composed of the above parts will be described. When using the contents, first, the cap 8 is rotated in the opening direction with respect to the container body 2, and the container body 2 and the cap 8 are then rotated. 2, after the cap is removed as shown in FIG. 2, the exterior body 6 is then rotated in the circumferential direction with respect to the guide cylinder 4, and the exterior body 6 and (knurls) are removed. The screw cylinder 5 fixed in the circumferential direction (by engagement with the groove) is rotated, and the pin 33 of the receiving cylinder 3 penetrating the guide hole 45 of the guide cylinder 4 is rotated into the screw groove 51 of the rotating screw cylinder 5. Is lifted up along the guide hole 45 of the guide cylinder 4 to raise the receiving cylinder 3 to raise the contents held on the pedestal 31 of the receiving cylinder 3, and the contents from the upper end of the guide cylinder 4 And the contents are ready for use To so that.

  In addition, after the contents are used, a procedure reverse to the above procedure is performed. That is, first, the exterior body 6 is rotated in the opposite direction with respect to the guide cylinder 4, and the protruding contents are guided to the guide cylinder 4. Then, the cap 8 is put on the container body 2, the cap 8 is rotated in the closing direction, the container body 2 and the cap 8 are screwed together, and the cap 8 is attached to the container body 2. As a result, the contents are brought into a state before being used.

  By the way, in the feeding container as described above, the receiving tube 3 for holding the rod-shaped contents has a flat plate-shaped (disk-shaped) pedestal portion for holding the rod-shaped contents as described above. 31 is formed in the cylinder, ribs 32 for fixing the contents are formed on the inner peripheral surface of the receiving cylinder 3, and the screw pins 33 projecting outward are symmetrical on the outer peripheral surface of the lower part of the receiving cylinder 3. A centering protrusion 34 that protrudes at a position and contacts the inner peripheral surface of the guide tube 4 is formed in an annular shape on the outer peripheral surface of the upper end portion of the receiving tube 3.

  In such a receiving cylinder 3, in this embodiment, as shown in FIGS. 3 and 4, the filling port 35 for filling the contents (molten contents) has a flat plate shape (disc shape). Opening at the center of the pedestal portion 31 and claw portions 36 for fixing the contents are formed at four locations at equal intervals in the circumferential direction of the peripheral portion of the filling port 35 so as to protrude outward and upward, respectively. In addition, vent holes 37 for venting gas having a smaller area than the filling port 35 are opened at four locations at equal intervals in the circumferential direction of the periphery of the pedestal portion 31.

  In the present embodiment, the vent hole 37 for venting gas is provided along the outer peripheral edge of the pedestal portion 31 when the receiving tube 3 is viewed from above (in plan view). The circumferential center position of the vent 37 is arranged to be shifted by 45 ° with respect to the straight line connecting the circumferential center position of the claw portion 36 and the center of the pedestal portion 31 formed in The central positions of the ribs 32 formed on the inner peripheral surface of the receiving cylinder 3 are arranged so as to be on the same radius.

  In the present embodiment, specifically, the inner diameter of the filling port 35 for filling the contents is 10.5 mm, the distance from the outer peripheral edge of the pedestal 31 to the filling port 35 is 5.25 mm, and the gas The length of the vent hole 37 for extraction in the container radial direction is set to 1.5 mm, and the length in the container circumferential direction is set to 5 mm. The shape of the vent hole 37 for gas venting is not limited to the circular arc shape as illustrated, but may be a circular shape or a polygonal shape. The number of vent holes 37 is in consideration of moldability and gas venting. The number is preferably about 2 to 8.

  When the contents are filled in the feeding container provided with the receiving cylinder 3 as described above, the receiving cylinder 3 is positioned at the lower limit in the guide cylinder 4 and the upper end opening of the guide cylinder 4 is exclusively used. After the mold cap (not shown) is sealed, the container body 2 is turned upside down after the receiving cylinder 3, the guide cylinder 4 and the mold cap define a molding space inside the container body 2. In the state of the posture, a filling nozzle is inserted from the opening 63 of the bottom 62 of the exterior body 6, and the molten content is filled into the molding space from the filling port 35 of the receiving cylinder 3.

  At this time, the molten content is filled until the content overflows from the filling port 35 and the vent 37 in consideration of shrinkage of the volume of the content after cooling and solidification and removal of aspiration generated during filling. After filling the melted contents, the contents are cooled and solidified by cooling the container body 2 as a whole.

  According to the feeding container of the present embodiment filled with the melted content as described above, only the rib 32 formed on the inner peripheral surface of the receiving tube 3 is used to hold the cooled and solidified rod-shaped content. In addition, since a flat pedestal portion 31 is provided in the cylinder of the receiving tube 3 and the claw portion 36 is formed on the pedestal portion 31, the pedestal portion 31 securely holds the rod-shaped contents.

  In addition, when filling the melted content, the content filling port 35 is opened at the center of the pedestal portion 31, and the vent hole 37 for venting gas is opened at the periphery thereof. Therefore, the aspiration generated at the time of filling the melted contents is quickly discharged from the vent hole 37 for venting formed separately from the filling port 35, and as a result, the content after cooling and solidification. It is possible to prevent the contents from being damaged by generating voids due to bubbles in the object and becoming brittle.

  In addition, when the contents are filled, the contents are cooled and solidified in a state where the contents are overflowed from the vent hole 37 for degassing, so that the contents are overflowed by the contents overflowing to the container bottom side of the pedestal 31. Since it can fix to the base part 31, it can prevent more reliably that the content falls from the receiving cylinder 3. FIG.

  In the present embodiment, the vent hole 37 for venting gas is opened along the outer peripheral edge of the pedestal portion 31, so that the inner peripheral surface of the receiving tube 3 and the pedestal portion are formed at the portion of the vent hole 37. The connection part 31 does not become a corner part where the aspiration generated during filling of the contents tends to accumulate, but becomes a relatively smooth surface and can be vented efficiently, and after cooling and solidification It is possible to reliably prevent the occurrence of voids due to bubbles in the contents of.

  Further, in the present embodiment, the vent 37 for venting the gas from the claw portion 36 formed in the pedestal portion 31 is from a straight line connecting the circumferential center position of the pedestal portion 31 and the center of the pedestal portion 31. Since it is arranged so as to be in a position shifted in the circumferential direction (shifted by 45 °), the effect of retaining the contents in the pedestal portion 31 by the claw portion 36 and overflowing from the vent hole 37 for degassing The holding effect of the contents in the pedestal portion 31 due to the solidification of the contents allows a sufficient holding force to be applied over a wide range on the entire circumference of the pedestal portion 31, thereby further removing the contents from the receiving tube 3. This can be prevented more reliably.
