Description

  The present invention relates to a liquid cosmetic application container that contains liquid cosmetics such as lip gloss.

In a conventional liquid cosmetic application container, a fixed shaft integrated with a lid constituting the liquid cosmetic application container together with an application container main body for storing liquid cosmetic such as lip gloss, and the tip of the fixed shaft are fixed. Shigoki is housed in the opening so that the liquid cosmetic material excessively adhered to the surface of the coated body can be wiped off as appropriate. That is, the mushroom is formed with a substantially cylindrical mushroom body, and a mushroom piece having elasticity in an inverted frustoconical shape so that an insertion hole is disposed at the tip on the inner peripheral surface of the mushroom body, The inner diameter of the insertion hole of the mushroom piece is substantially smaller than the outer diameter of the fixed shaft.
Therefore, when taking out the application body fixed to the lid constituting the liquid cosmetic application container via the fixed shaft, the fixed body integrated with the cover body and the application body fixed to the tip of the fixed shaft Since the swordfish pieces, which are elastic bodies, are in close contact with the surface of the liquid, the liquid cosmetic material excessively adhered to the surface of the fixed shaft and the applied body fixed to the tip of the fixed shaft is appropriately wiped off, dripping, etc. Can be prevented.

By the way, when the application body that is fixed to the lid body via the fixed shaft is stored in the coating container body, the side surface of the fixed shaft and the surface of the application body that is fixed to the tip of the fixed shaft are squeezed. Shigoki pieces are in close contact.
Therefore, in the squeeze in the application container main body, the air is compressed by the volume of the inserted fixed shaft and the application body fixed to the tip of the fixed shaft.
As a result, a so-called pump-up phenomenon in which the lid body pops out due to the repulsion of compressed air in the mushroom or liquid cosmetics stored in the application container body may be ejected.
In addition, if the liquid cosmetic stored in the application container body is an oily liquid cosmetic such as lip gloss, the frictional force against the side surface of the holding shaft of the scabbard piece is reduced, and the pump-up phenomenon and the liquid cosmetic Ejection tends to occur remarkably.

  Therefore, in order to prevent a pump-up phenomenon that occurs when the application body is stored in the application container body and the ejection of liquid cosmetics, the squirrel is divided into a plurality of squirrel pieces, and the divided squirrel pieces are applied as a whole. In this case, each squirrel piece is arranged in a stepwise manner in the vertical direction (see Patent Documents 1 and 2). That is, in the squirrel, when the application shaft and the application brush of the applicator are stored in the storage container body, the air in the storage container body is discharged to the outside through the space formed by the divided stalk pieces. Will not occur. Therefore, it is possible to reliably prevent the pump-up phenomenon and the liquid cosmetic jet.

  However, in the case of dividing the mushroom into a plurality of mushroom pieces as described above, it is necessary to combine the upper and lower pins of the mold in steps according to the arrangement of the mushroom pieces to be molded. It becomes complicated. As a result, the mold cost is greatly increased.

  In addition, high pressure is applied to the upper and lower pins of the mold, and wear is severed by repeatedly opening and closing the mold and taking out the molded product. Therefore, the adhesiveness of the mold is lowered, and burrs and the like are easily generated in the molded product. Therefore, frequent maintenance is required, which increases the maintenance cost.

  The problem to be solved is that it is not possible to easily and inexpensively manufacture a mushroom that can reliably prevent the pump-up phenomenon and the liquid cosmetics from being ejected.

As the first feature,
The liquid cosmetic is stored, and a male screw part is screwed on the outer peripheral surface, and an application container body that forms an opening that houses elastic shigoke inside, and a female screw part is screwed in the opening. And a cap formed by holding the application body at the tip of the holding shaft to which the root portion is inserted,
The mushroom is a substantially cylindrical mushroom main body inserted and held in the opening of the application container main body, and the inner peripheral edge of the tip of the mushroom main body over the entire inner circumferential surface of the mushroom main body is substantially smaller than the outer diameter of the fixed shaft. It consists of a squirrel piece formed in an inverted frustoconical shape with an insertion hole having a small diameter,
The surface of the mushroom piece forms one or more steps from the inner periphery of the insertion hole toward the inner surface of the mushroom body.

For this reason, when the cap is inserted through the applicator container body to store the applicator that is held by the cap via the holding shaft, the surface of the shigoki piece is elastic against the side of the holding shaft that holds the applicator. Hold it tightly.
Since one or more steps are formed on the surface of the mushroom, a space is formed by the side surface of the holding shaft and the steps formed on the surface of the mushroom. Moreover, since the step formed on the surface of the swordfish is formed from the inner peripheral edge of the swordfish insertion hole toward the inner peripheral surface of the swordfish body, it is formed by the side surface of the holding shaft and the step on the surface of the swordfish. The space is an air flow passage that communicates the inside and outside of the inside of the coating container main body.
As a result, the air inside the mushroom can be discharged to the outside through the air flow passage according to the insertion of the application body. Therefore, even if the application body is stored in the application container body through the mushroom, compressed air is not generated and the cap The pump-up phenomenon and the liquid cosmetics can be prevented from being ejected.

  Here, in the mushroom built in the opening of the application container body, the mushroom piece having elasticity that is in close contact with the side surface of the holding shaft that holds the application body at the tip is integrally formed in the middle of the inner peripheral surface in the mushroom body. In addition to the one (see FIG. 3), it may be integrally formed in the opening in the bottom direction of the coating container main body in the cylindrical swordfish main body (see FIG. 6).

  Further, the length of the step formed on the surface of the mushroom corresponds to the length of the air flow passage that discharges the air in the mushroom in the coating container body to the outside. Therefore, the length of the step formed on the surface of the sword piece is the length from the inner peripheral edge of a part or more of the sword piece that elastically deforms and adheres to the side surface of the holding shaft when the application body is stored. Is required at a minimum.

  In addition, the squirrel embedded in the opening of the application container body is not configured to be divided into a plurality of parts, but is formed integrally with the inverted frustoconical shape on the inner peripheral surface of the squirrel body and has a simple shape. It can be easily manufactured.

As the second feature,
The liquid cosmetic is stored, and a male screw part is screwed on the outer peripheral surface, and an application container body that forms an opening that houses elastic shigoke inside, and a female screw part is screwed in the opening. And a cap formed by holding the application body at the tip of the holding shaft to which the root portion is inserted,
The mushroom is a substantially cylindrical mushroom main body inserted and held in the opening of the application container main body, and the inner peripheral edge of the tip of the mushroom main body over the entire inner circumferential surface of the mushroom main body is substantially smaller than the outer diameter of the fixed shaft. It consists of a squirrel piece formed in an inverted frustoconical shape with an insertion hole having a small diameter,
The surface of the squirrel piece is divided into a plurality of squeeze piece split parts, and from the inner peripheral edge of the insertion hole to the inner peripheral surface direction of the squirrel body at the boundary with the adjacent squeeze piece split part among the plurality of squirrel piece split parts. A plurality of steps are formed.

  Therefore, in the application container main body, the air in the squirrel is a plurality of steps formed at the boundary between the squeeze piece dividing portions adjacent to each other on the surface of the squirrel piece, and the side surface of the holding shaft that is inserted into the insertion hole of the squirrel piece. Can be discharged to the outside through a plurality of air flow passages formed by. As a result, even if the application body is stored in the application container body through the squeeze, compressed air is not generated, and the pump-up phenomenon and the ejection of the liquid cosmetic can be prevented.

As the third feature,
The liquid cosmetic is stored, and a male screw part is screwed on the outer peripheral surface, and an application container body that forms an opening that houses elastic shigoke inside, and a female screw part is screwed in the opening. And a cap formed by holding the application body at the tip of the holding shaft to which the root portion is inserted,
The mushroom is a substantially cylindrical mushroom main body inserted and held in the opening of the application container main body, and the inner peripheral edge of the tip of the mushroom main body over the entire inner circumferential surface of the mushroom main body is substantially smaller than the outer diameter of the fixed shaft. It has a small diameter and consists of a squirrel piece formed in an inverted truncated cone shape having an insertion hole having a small diameter part formed to protrude in the inner diameter direction in a part thereof,
The surface of the squirrel piece is formed by projecting a ridge portion connected to a small diameter portion formed at the inner periphery of the insertion hole of the squeeze piece from the inner peripheral edge of the insertion hole toward the inner peripheral surface of the squirrel body. A plurality of steps are formed along both sides of the protrusion.

  Therefore, in the coating container main body, the air in the squirrel is a plurality of steps formed from the inner peripheral edge of the insertion hole toward the inner peripheral surface of the squirrel main body along the ridge formed on the surface of the squirrel piece. And an air flow passage formed by a holding shaft inserted into the insertion hole of the squirrel piece can be discharged to the outside. As a result, even if the application body is stored in the application container body through the squeeze, compressed air is not generated, and the pump-up phenomenon of the cap and the ejection of the liquid cosmetic can be prevented.

  In addition, if the area and arrangement of the ridges formed on the surface of the sledge piece are changed, the air flow passage formed by the steps formed along both sides of the ridges and the side surfaces of the holding shaft can be changed. The arrangement will change. As a result, it is possible to more efficiently discharge the air in the mushroom to the outside so as to prevent the generation of compressed air that causes the pump-up phenomenon and the ejection of the liquid cosmetic.

As the fourth feature, based on the first to third features,
The base portion is inserted into the cap, the engaging portion is attached to the side surface of the holding shaft that holds the application body at the tip thereof, and the engaging portion of the side surface of the holding shaft is formed on the inner peripheral surface of the squirrel body constituting the squirrel. And an engaged portion that is tightly fitted to each other.

  Therefore, when the cap is screwed together with the opening of the application container main body in order to attach the cap to the application container main body, the engaging portion disposed on the side surface of the holding shaft of the cap It fits tightly to the fitted part arrange | positioned at the inner peripheral surface of the shigoki main body to comprise. As a result, the air flow passage formed by the side surface of the holding shaft and the level difference formed on the surface of the shigoki is closed, so that the liquid cosmetic can be prevented from leaking through the air flow passage.

  In addition, when the application body is stored in the application container main body as described above, the liquid cosmetic material stored in the application container main body from the air flow passage is prevented from leaking and is fitted on the side surface of the holding shaft. The mating portion and the fitted portion disposed on the inner peripheral surface of the shigoki body constituting the shigoki are tightly fitted to each other, but an elastic O-ring is provided on the side surface of the holding shaft, and the O-ring The air flow passage may be closed by deformation of the above.

  The squeeze of the liquid cosmetic application container according to the present invention is configured such that when the holding shaft and the application body held at the tip of the holding shaft are accommodated in the application container main body, the air in the squirrel is separated from the step between the surface of the squirrel piece and the holding shaft. It can be discharged reliably from the air flow passage formed by the side surface, so that pump-up phenomenon and liquid cosmetics can be prevented from being ejected, and the shape of the squirrel itself can be simplified and manufactured easily to improve work efficiency As a result, the manufacturing cost can be reduced.

  What is shown in FIG. 1 is a liquid cosmetic application container 1 that is Embodiment 1 of the present invention, and the liquid cosmetic application container 1 includes an application container main body 2 that stores a liquid cosmetic 3 such as lip gloss, The cap 10 is formed by holding the application body 12 at the tip thereof via the holding shaft 11.

First, the coating container main body 2 is formed by integrally forming an opening 4 formed by screwing a male screw portion 5 on the outer peripheral surface and internally having a squeak 6 having elasticity.
Here, the squirrel 6 includes a substantially cylindrical squirrel body 7 that is inserted and held in the opening 4 of the application container body 2, and an inner peripheral edge at the tip of the squirrel body 7 over the entire inner peripheral surface 7a. It is composed of a squirrel piece 8 formed in an inverted truncated cone shape having an insertion hole 9 in which the inner diameter of 9 a is substantially smaller than the outer diameter of the fixed shaft 11.
The surface of the squirrel piece 8 is formed by forming a step 8b from the inner peripheral edge 9a of the insertion hole 9 toward the inner peripheral surface 7a of the squirrel body 7 at the boundary between the two squeeze piece divided portions 8a. is there.
It should be noted that the surface of the squirrel piece 8 is not only divided into two squeeze piece split parts 8a as described above, but, for example, is divided into four parts as four squirrel piece split parts 8a 'to form four steps 8b'. May be formed at positions facing each other (see FIG. 4).
Further, the inner peripheral surface 7a of the shigoki body 7 is tightly fitted with a protruding peripheral edge 13b as a fitting part on the side surface of the main body part 13a of the seal body 13 which is externally mounted on the holding shaft 11 of the cap 10. A fitting groove 7b is formed as a joint portion.

On the other hand, the cap 10 has a female screw portion 10b screwed into the opening portion 10a, and the base portion 11a of the holding shaft 11 is inserted to hold the application body 12 at the tip of the holding shaft 11. It is.
In addition, in order to prevent the liquid cosmetic 3 stored in the application container main body 2 after storing the application body 12 from leaking to the outside through the air flow path 14 described later, the air flow path 14 needs to be reliably closed. There is. Therefore, a main body portion 13a formed in an inverted truncated cone shape so as to be in close contact with the surface of the squirrel piece 8, and a fitted portion provided in the side surface of the main body portion 13a as a groove in the inner peripheral surface 7a of the swordfish main body 7. A sealing body 13 including a projecting peripheral edge 13b as a fitting portion projecting in the radial direction on the side surface 11a of the holding shaft 11 tightly fitted to the fitting groove 7b is externally provided. Therefore, when the application body 12 is stored in the application container main body 2, the main body portion 13 a of the seal body 13 of the holding shaft 11 is in close contact with the squirrel piece 8, and the protruding peripheral edge 13 b provided on the side surface of the main body portion 13 a is the squirrel body 7. The air flow passage 14 formed by the side surface 11a of the holding shaft 11 and the step 8b formed on the surface of the squirrel piece 8 is closed by tightly fitting with the fitting groove 7b provided in the inner peripheral surface 7a. As a result, the liquid cosmetic 3 stored in the application container body 2 can be prevented from leaking outside through the air flow passage 14.

  As described above, since the liquid cosmetic application container 1 according to the first embodiment of the present invention is configured, the following is performed when the application body 12 is stored in the application container body 2.

That is, in order to store the application body 12 held at the tip of the cap 10 via the holding shaft 11 in the application container main body 2, the application body 12 is passed through the squeeze 6 built in the opening 4 of the application container main body 2. When inserted, the squirrel piece 8 of the scab 6 comes into close contact with the side surface 11a of the holding shaft 11 with elasticity.
The surface of the squirrel piece 8 of the sword 6 that is in close contact with the side surface 11a of the holding shaft 11 is formed at the boundary between the two squeeze piece divided portions 8a from the inner peripheral edge 9a of the insertion hole 9 to the inner peripheral surface of the squirrel body 7. A step 8b is formed in the 7a direction.
Therefore, an air flow passage 14 is formed in the coating container main body 2 by communicating the inside of the squirrel 6 with the outside by the side surface 11a of the holding shaft 11 and the step 8b formed on the surface of the squirrel piece 8. become.
Accordingly, when the application body 12 is inserted into the application body body 2 through the squirrel 6 even though the side surface 11a of the holding shaft 11 and the squealing piece 8 of the squeal 6 are in close contact with each other, the air in the squirrel 6 flows through the air. Compressed air is not generated by being discharged to the outside through the passage 14.
As a result, the pump-up phenomenon of the cap 10 and the ejection of the liquid cosmetic 3 can be reliably prevented.
Then, the cap 10 is formed by screwing the female screw portion 10b screwed into the opening portion 10a of the cap 10 and the male screw portion 5 screwed to the outer peripheral surface of the opening portion 4 of the coating container main body 2. When the application container main body 2 is integrated, the main body portion 13a of the sealing body 13 that is sheathed on the side surface 11a of the holding shaft 11 is in close contact with the squirrel piece 8 and at the same time protrudes from the side surface of the main body portion 13a of the sealing body 13. The protruding peripheral edge 13b is closely fitted with a fitting groove 7b formed in the inner peripheral surface of the shigoki body 7. Therefore, the liquid cosmetic 3 such as lip gloss stored in the application container body 2 does not leak to the outside through the air flow passage 14.

Reference numeral 1 ′ denotes a liquid cosmetic container that is Embodiment 2 of the present invention. The liquid cosmetic container 1 ′ that is Embodiment 2 of the present invention and the liquid cosmetic container 1 of Embodiment 1 are an application container main body. 2 and the cap 10 are generally the same.
However, the sword 6 ', particularly the sword 6' that forms the sword 6 'together with the squirrel body 7' is different.
That is, the squirrel 6 'has a substantially cylindrical squirrel body 7' fitted and held in the opening 4 of the application container body 2, and the tip of the squirrel body 6 'over the entire inner peripheral surface 7a' of the squirrel body 7 '. An inverted frustoconical shape in which the inner peripheral edge 9a 'is substantially smaller than the outer diameter of the fixed shaft 11, and an insertion hole 9' having a small diameter portion 15 formed so as to protrude in the inner diameter direction is provided in a part thereof. It consists of a scabbard piece 8 'formed in a shape.
Then, on the surface of the scabbard piece 8 ', the protrusion 16 connected to the small diameter part 15 formed so as to occupy 1/2 in the inner peripheral edge 9a' of the insertion hole 9 'of the swordfish piece 8' is inserted into the hole. It forms in the inner peripheral surface 7a 'direction of shigoki body 7' from the inner peripheral edge of 9 '. Accordingly, a step 8b ′ is formed along both sides of the protrusion 16.
Note that the protrusion 16 on the surface of the sword piece 8 ′ connected to the small diameter portion 15 formed at the inner peripheral edge 9a ′ of the insertion hole 9 ′ of the sword piece 8 ′ has a holding shaft 11 for holding the application body 12 at the tip. As shown in FIGS. 8 (a) to 8 (d), the position and area of the ridges 16 occupying the surface of the squirrel piece 8 ′ can be varied or the ridges 16 can be changed depending on the thickness of the liquid cosmetic 3 and the properties of the liquid cosmetic 3. Is appropriately selected.

As described above, the squirrel 6 ′ of the liquid cosmetic container 1 ′ that is the second embodiment of the present invention is configured, so that it is formed along both sides of the ridge 16 formed on the surface of the squirrel piece 8 ′. The air flow passage 14 is formed by the step 8 ′ and the side surface 11 a of the fixed shaft 11 to communicate the inside and the outside of the scab 6 ′ in the application body 2.
Therefore, even if the application body 12 is inserted into the application body main body 2 through the squeeze 6 ', the air in the squeeze 6' is smoothly discharged to the outside, so that compressed air is not generated.
As a result, the pump-up phenomenon of the cap 10 and the ejection of the liquid cosmetic 3 such as lip gloss can be reliably prevented.

  The squirrel that forms a stepped piece with a step on the surface can reliably prevent the pump-up phenomenon of the cap that occurs when the application body is stored in the application container body and the ejection of liquid cosmetics, so only lip gloss It can also be applied to a liquid cosmetic application container that stores all liquid cosmetics such as mascara.
