Description

  The present invention relates to a liquid application container.

  Conventionally, as a liquid application container for applying a liquid such as an antiperspirant, for example, a so-called roll-on type application container described in Patent Document 1 has been widely used. The roll-on-type application container described in Patent Document 1 contains a highly viscous drug in the container A, and includes a holding cylinder 10 that holds the ball C in the mouth 1 of the container A. A plug B is attached. As shown in FIG. 4 of Patent Document 1, the usage method of the application container configured in this way is as follows. First, the container A is turned upside down to move the ball C, and the contents in the container A are passed through the communication hole 16. Is allowed to flow into the liquid reservoir 17 from between the ball C and the protruding ring 12. Then, the ball C is pressed against the surface to be coated and rolled, and a gap is formed between the ball C and the upper end 13 of the holding cylinder 10. It is poured out from between C, adhered to the ball C, and applied to the surface to be coated.

Japanese Patent Laying-Open No. 2005-186997 (see FIG. 3, FIG. 4, paragraph “0023”)

  As described above, in the conventional application container described above, there is a gap between the ball C and the upper end 13 of the holding cylinder 10 in order to make it easy to discharge the internal liquid and to ensure smooth rotation of the ball C. Needed to be formed. However, in the application container in which a gap is formed between the ball C and the upper end 13 of the holding cylinder 10 as described above, when a low-viscosity liquid is accommodated in the container A and used, the application container is used upside down. When this occurs, there may arise a problem that the liquid in the container A drips from between the ball C and the upper end 13 of the holding cylinder 10. Then, this invention makes it a subject to provide the liquid application container which does not drips at the time of use even if it is a liquid with low viscosity.

  The liquid application container according to the present invention contains a liquid and has a container body having a mouth, a holding member having one end attached to the mouth and a recess formed on the other end, and the recess in the recess. A ball that is rotatably held by a holding member, and the holding member has a through hole that communicates the inside of the container body and the inside of the recess, and the upper end of the side wall surface of the recess extends over the entire circumference. An annular protrusion having a pointed tip that contacts the ball is formed so as to surround the through hole.

  According to the liquid application container of the present invention, the annular protrusion is in contact with the ball, and the upper end of the side wall surface of the recess is also in contact with the ball over the entire circumference. The ball is held without moving up and down. For this reason, the ball is in contact with the upper end of the side wall surface of the recess, and even if a liquid with low viscosity is accommodated in the container body, the liquid does not sag. Further, since the ball is in contact with the annular protrusion and the upper end portion of the recess side wall surface in this way, the liquid does not easily accumulate in the liquid reservoir portion defined by the ball, the recess side wall surface, and the annular protrusion. Therefore, even if the ball is retracted by strongly pressing the ball and a gap is generated between the ball and the upper end portion of the recess side wall surface, the liquid does not drip from the gap. Therefore, for example, when applying an external anti-inflammatory analgesic or the like to a stiff shoulder portion or muscle pain portion using this liquid application container, the user strongly presses the portion with a ball so as to loosen the stiff shoulder portion. It can also be applied and a pleasant feeling of use can be enjoyed. Further, in this liquid application container, both the upper end of the side wall surface of the recess and the annular protrusion are in contact with the ball, but the annular protrusion has a pointed tip which is a portion in contact with the ball, so that the friction resistance Becomes smaller and can ensure a smooth rotation of the ball. The holding member described above may be formed as a separate member from the container body and then attached to the mouth, or the holding member may be attached to the mouth by being integrally formed with the container body.

  The holding member includes a cylindrical side wall portion serving as a side wall of the concave portion, and an inward flange portion extending radially inward from a lower end portion of the side wall portion so as to serve as a bottom portion of the concave portion. The protrusion may be configured to be formed on the inward flange portion. In this case, the elastic modulus of the inward flange portion is preferably about 50 to 200 MPa. By being comprised in this way, a flange part can play the role of a cushion and can ensure the smooth rotation of a ball | bowl. In addition, the said cylindrical shape of a side wall part is a concept containing substantially cylindrical shape, square tube shape, etc.

  The material of the ball is not particularly limited, but may be made of plastic or metal, preferably made of metal, and more preferably made of stainless steel. When the liquid application container of the present invention is used for a stiff shoulder portion, the weight of the ball can be increased when the ball is made of metal, so that the affected area can be more effectively pressed. Metal is preferable because the ball is easy to rotate smoothly because of its low frictional resistance, and since it is difficult to deform, it is difficult to form a gap between the upper end portion of the recess side wall surface and the annular projection, so that liquid does not leak easily. A material that does not corrode due to liquid components may be used.

  Moreover, it is preferable that the viscosity of the liquid accommodated in the container body is about 10 to 1,000 cP.

  According to the liquid application container according to the present invention, it is possible to prevent a liquid having a low viscosity from dripping during use.

FIG. 1 is a front view showing an embodiment of a liquid application container according to the present invention. FIG. 2 is a view showing a state in which the lid of FIG. 1 is removed. FIG. 3 is a cross-sectional view showing an enlarged part of an embodiment of the liquid application container according to the present invention.

  Hereinafter, embodiments of a liquid application container according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the liquid application container 1 according to the present embodiment mainly includes a container body 2, a holding member 3, a ball 4, and a lid 5, and has a generally cylindrical shape as a whole. ing.

  The container body 2 is a container made of polyethylene, polypropylene, or the like, and includes a bottom portion 21, a cylindrical portion 22 that extends upward from the bottom portion 21, and a mouth portion 23 that extends upward from the upper end of the cylindrical portion 22 via a shoulder portion 24. have. The mouth portion 23 is formed with a male screw 231 on the outer peripheral surface thereof so as to be screwed with the lid 5. Further, the mouth portion 23 has a smaller diameter than the cylindrical portion 22, and a fitted portion 232 for fitting a fitting portion 33 of the holding member 3 described later is formed in an annular shape at the upper end ( (See FIG. 3).

  The container body 2 configured in this manner contains a liquid therein. Examples of the liquid include alcohols such as ethanol and isopropanol, polyhydric alcohols such as propylene glycol and dipropylene glycol, and purified water. Mention may be made of low-viscosity liquids. Various components can be appropriately blended in the liquid depending on the application. In the case of pharmaceuticals, anti-inflammatory analgesic components (eg, ferbinac, indomethacin, glycol salicylate, etc.), antihistamines (eg, diphenhydramine hydrochloride, chlorpheniramine maleate, etc.), blood circulation promoting components (eg, vanillyl nonanoate, etc.) ), A refreshing agent (for example, l-menthol, etc.), and other antiseptics, stabilizers, pH adjusters and the like, but are not limited thereto. In the case of cosmetics, antiperspirant components (for example, chlorohydroxyaluminum, zinc paraphenolsulfonate), bactericidal components (for example, benzalkonium chloride, benzethonium chloride, etc.), deodorant components (for example, Clara extract, etc.) ), And fragrances, but are not limited thereto. The viscosity of this liquid can be preferably about 10 to 1,000 cP. The viscosity of the liquid can be measured, for example, using a B-type viscometer (Brookfield DV-II) with a T-E1 rotor at a rotation speed of 6 rpm.

  As shown in FIGS. 2 and 3, the holding member 3 is a member that holds the ball 4 by the concave portion 30, and is attached to the container body 2 on the lower end side (one end side), and the upper end side (the other end). A recess 30 is formed on the side). The holding member 3 includes a side wall portion 31 serving as a side wall of the concave portion 30, an inward flange portion 32 serving as a bottom portion of the concave portion 30, and a fitting portion that fits into the fitted portion 232 of the mouth portion 23 of the container body 2. 33.

  The side wall portion 31 has a substantially cylindrical shape, and the upper end portion 311 is slightly curved inward to hold the ball 4, and the inner diameter of the upper end portion 311 is smaller than the outer diameter of the ball 4. ing. The upper end 311 of the side wall 31 is in contact with the ball 4 over the entire circumference.

  The inward flange 32 extends from the lower end portion of the side wall portion 31 so as to incline downward in the radial direction. The upper surface of the inward flange 32 is smoothly connected to the inner peripheral surface of the side wall portion 31, and the upper surface of the inward flange 32 and the inner peripheral surface of the side wall portion 31 form a substantially spherical concave portion 30 whose upper portion opens. Is defined. A through hole 34 is formed at the bottom center of the recess 30, that is, at the center of the inward flange 32. Since the through hole 34 communicates the recess 30 of the holding member 3 with the inside of the container body 2, the liquid in the container body 2 is supplied to the balls 4 through the through hole 34. It has become.

  An annular projection 35 is formed on the upper surface of the lower end portion of the inward flange 32 so as to surround the through hole 34. The annular protrusion 35 includes a base portion 351 having a trapezoidal cross section, and a pointed portion 352 having a triangular cross section formed on the upper surface of the base portion 351. Since the ball 4 is in contact with the pointed portion 352 of the annular protrusion 35, the frictional resistance with the annular protrusion 35 is reduced, and smooth rotation of the ball 4 can be ensured. Further, since the holding member 3 is in contact with the ball 4 by the upper end portion 311 of the side wall portion 31 and the pointed end portion 352 of the annular protrusion 35 and holds the ball 4 in the recess 30, the liquid application container 1 is moved up and down. The ball 4 does not move up and down even if it is turned upside down. Accordingly, no gap is formed between the ball 4 and the annular protrusion 35, so that it is difficult for the liquid to flow into the liquid reservoir 36 from the through hole 34. Even if the liquid is accumulated in the liquid reservoir 36 defined by the surface of the ball 4 and the inner wall surface of the recess 30, the ball 4 is in contact with the upper end 311 so that the liquid container 1 is turned upside down or Even if it is shaken, liquid does not leak.

  The fitting portion 33 extends from the lower end portion of the side wall portion 31 to the outside and then extends downward. The fitting portion 33 has a hook-like cross section and is formed at the upper end of the mouth portion 23 of the container body 2. It is formed so as to fit into the portion 232.

  The ball 4 is spherical and is accommodated in the concave portion 30 of the holding member 3, and is in contact with the upper end portion 311 of the side wall portion 31 in the upper portion thereof and in contact with the annular protrusion 35 in the lower portion thereof. , Held in the recess 30. The diameter of the ball 4 is preferably about 10 to 30 mm, and the material of the ball 4 can be various. For example, the ball 4 is preferably made of metal, particularly stainless steel. The hardness of the ball 4 is preferably about 100 to 200 HB, and the sphericity is preferably about 0 to 5 μm. The hardness of the ball 4 can be measured by Brinell hardness (HB: JIS Z 2243).

  The lid 5 has a substantially cylindrical shape, and a pressing projection 52 for pressing the ball 4 is formed in an annular shape on the inner surface of the top plate portion 51. Further, on the inner surface of the lower portion of the side wall surface of the lid 5, a female screw portion 53 that is screwed with the male screw 231 formed in the mouth portion 23 of the container body 2 described above is formed. The outer diameter of the lid 5 is substantially the same as the outer diameter of the cylindrical portion 22 of the container body 2.

  When the liquid application container 1 configured as described above is used, the lid 5 is first removed, and the ball 4 is pressed against the portion where the liquid is to be applied, and the ball 4 is rotated. Thereby, the liquid accommodated in the container main body 2 adheres to the surface of the ball 4 through the through hole 34 of the holding member 3, and the liquid attached to the surface of the ball 4 is moved to the desired location by rotating the ball 4. To be applied. At this time, even when the container main body 1 is turned upside down (so that the ball 4 faces downward), the ball 4 is supported by the annular protrusion 35 and the upper end portion 311 of the side wall portion 31. In this state, the annular protrusion 35 and the upper end 311 of the side wall 31 are in contact with each other without moving up and down. As a result, since no gap is formed between the ball 4 and the upper end portion 311, the liquid does not leak and even if the liquid has a low viscosity, it does not sag.

  Further, as described above, since the ball 4 is in contact with the annular protrusion 35 and the upper end portion 311, it is difficult for the liquid to accumulate in the liquid reservoir 36. For example, the ball 4 is strongly pressed until the ball 4 is retracted. Even when a gap is generated between the ball 4 and the upper end portion 311, the liquid does not drip. For this reason, for example, when it is desired to apply a liquid (for example, an external anti-inflammatory analgesic or the like) in the liquid application container 1 to the muscle pain portion, the muscle pain portion can be applied while strongly pressing with the ball 4. In this case, by setting the elastic modulus of the inward flange 32 to about 50 to 200 MPa, a comfortable pushing feeling can be experienced.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various change is possible unless it deviates from the meaning of this invention.

  For example, in the above-described embodiment, the annular protrusion 35 is configured by the base portion 351 and the pointed end portion 352, but is not particularly limited to this configuration as long as the tip is sharpened. Can have a triangular cross-section.

  Further, although the annular protrusion 35 is formed on the inward flange portion 32, the inward flange portion 32 can be omitted and the annular protrusion 35 can be directly formed on the side wall portion 31.

  Next, the Example using a pharmaceutical (anti-inflammatory analgesic) as a liquid used with the application | coating container of this invention is described. In each example, the liquid application container 1 having the same shape as the above embodiment was used.

  Example 1: 3 g of ferbinac, 12 mg of nonanoic acid vanillylamide, 6 g of l-menthol, 100 mg of chlorpheniramine maleate, 0.08 g of glycyrrhetinic acid, 10 g of propylene glycol, 2 g of diisopropanolamine, 0.04 g of BHT and 65 mL of ethanol were mixed. 50 mL of an anti-inflammatory analgesic obtained by mixing an appropriate amount of water so that the total amount becomes 100 mL (viscosity: 580 cP—viscosity when measured at 20 ° C. using the above-described B-type viscometer), container (made of polyethylene) And a holding member (elastic modulus: 150 MPa) holding a stainless steel ball having a diameter (19 mm), hardness (160 HB), and sphericity (1 μm).

  Example 2: Same as Example 1 except that 3 g of felbinac was replaced with 10 mg of indomethacin.

  Example 3 The same as Example 1, except that the stainless steel balls were replaced with PP balls having a diameter (19 mm), hardness (R80 to 110), and sphericity (10 μm).

  In any of the liquid application containers of Examples 1 to 3, the liquid (medicine) does not sag even when the application container is used upside down. When the part is strongly pressed with a ball so as to loosen the stiff shoulder, etc., Examples 1 and 2 using a stainless steel ball are pressed against the stiff shoulder compared to Example 3 using a PP ball. It was excellent in the property and the feeling of use was excellent.
