Description

  The present invention relates to a roll-on container in which a roll-on applicator having an application ball is mounted on the mouth of a container body, and more particularly to a technique that enables a predetermined amount of content liquid to be applied.

  Conventionally, as described in Patent Document 1, for example, as a roll-on container, it has an application ball and an inner stopper that rotatably holds the application ball, and the application ball is placed on the application surface with the container turned upside down. It is known that the content liquid adhering to the application ball is transferred to the application surface and applied by rolling while being pressed.

  By the way, in the thing of patent document 1, since the content liquid in a container is discharged according to rolling of an application | coating ball | bowl, if the application | coating ball is rolled for a long time, much content liquid will be equivalent. If the viscosity of the content liquid is low, the content liquid may flow out more than necessary, and it is difficult to adjust the coating amount.

  On the other hand, in Patent Document 2, in a sphere holding plug having an insole provided with a liquid through-hole and having a sphere for application held in a sphere holding cylinder so as to enable adjustment of the coating amount, A valve body that opens and closes the liquid passage hole is provided between the sphere for use, and a water-containing substance is inserted between the valve body and the insole. There has been proposed a sphere holding stopper adapted to be applied via a sphere for use.

  However, the thing of the said patent document 2 has the problem that the liquid discharged is reduced as a result of the water content by a water-containing substance decreasing, for example, when a sag occurs in a water-containing substance with long-term use . In addition, there is a problem that the assembly work becomes complicated because the water-containing substance must be positioned and then inserted between the valve body and the insole.

  Therefore, an object of the present invention is to propose a roll-on container that can always apply a certain amount of content liquid and is easy to assemble.

  The present invention has been made to solve the above problems, and the roll-on container of the present invention is formed by mounting a roll-on type applicator on the mouth of the container body, and the applicator comprises: An application ball; a base member attached to the mouth portion of the container body; and a holding member that covers the base member and holds the application ball, and the holding member includes the application ball. And a holding wall that rolls and holds the application ball in a rollable manner, and a support portion that is held by the base member and supports the holding wall. The dome wall extends along the holding wall and forms a communication hole connected to the inside of the container body at the bottom, and the holding wall is disposed between the supporting portion and the holding wall. Energizing in a direction away from the dome wall, the holding wall and A bend wall that forms a metering chamber is integrally formed between the dome walls, and a pouring hole is formed in the holding wall for allowing the content liquid in the metering chamber to flow out to the surface of the coating ball. A valve body that is inserted into the communication hole by pushing the application ball against the urging force by the plug and closes the communication hole is provided integrally.

  In the roll-on container of the present invention, the valve body includes a base portion that forms a seal with the inner surface of the communication hole when the application ball is pushed in, and a gap from the base portion to the communication hole. It is preferable to comprise a guide portion that extends and is guided to guide the movement of the valve body.

  Moreover, in the roll-on container of this invention, it is preferable to provide the said extraction hole in two or more places in the position which mutually opposes.

  According to the present invention, since the metering chamber is formed between the holding member and the base member, it is possible to apply a certain amount of the content liquid, and this metering chamber has the urging force of the bend wall. It appears when the holding wall is separated from the dome wall, and since its urging force is always constant, the volume in the metering chamber is also constant, and a constant amount of content liquid can be always applied. Further, since the bend wall for moving the holding wall is formed integrally with the holding wall and the support portion, the positioning work required when assembling the water-containing substance of Patent Document 2 can be easily performed. Assembling can be performed and the number of parts can be reduced.

  Further, when the valve body is configured by a base portion that fits into the communication hole when the application ball is pushed in, and a guide portion that extends from the base portion with a gap to the communication hole to guide the movement of the valve body When the application ball is pressed against the application surface, the valve body can be surely inserted into the communication hole of the dome wall by the guide part, and a certain amount of content liquid is poured out and applied more reliably. It becomes possible to do.

  Furthermore, when two or more pouring holes are provided opposite to each other, the content liquid poured out from the quantitative chamber can be uniformly attached to the application ball, and the content liquid can be applied by the application ball. It becomes possible to carry out evenly.

Reference numeral 5 denotes a roll-on applicator that is attached to the mouth portion 3b of the container body 3. A cap 7 is attached to the mouth 3 b of the container body 3. Note that in the following description, descriptions relating to the vertical direction (for example, “upper”, “lower”, “bottom”) are all based on the state when the roll-on container is placed on a horizontal surface.

  The roll-on container 1 of the present embodiment is formed by mounting an applicator 5 on the mouth 3b of the container body 3, and as shown in FIGS. 1 and 2, the applicator 5 has a generally spherical application. A ball 9, a base member 11 attached to the mouth 3 b of the container body 3, and a holding member 13 that holds the base ball 11 and holds the application ball 9 are provided.

  The base member 11 includes a mounting cylinder 17 that is undercut engaged with a bulging ring 15 formed on the outer periphery of the protruding end of the mouth portion 3b of the container body 3, and an upper end of the mounting tube 17 along the protruding end of the mouth portion 3b. A ceiling wall 19 that extends inward, a seal ring 21 that hangs downward on the inside of the ceiling wall 19 and fits into the inner peripheral surface of the mouth portion 3b, and is connected to the inside of the ceiling wall 19 to be described later. The dome wall 25 extends along the holding wall 23. A communication hole 27 connected to the inside of the container main body 3 is formed at the bottom (center) of the dome wall 25, and an annular rib 25a for fitting and holding a fitting cylinder 29 described later is formed at the outer periphery of the upper end. ing.

  The holding member 13 extends along the application ball 9 and surrounds the outer periphery of the upper end portion of the dome wall 25 of the base member 11 and the holding wall 23 for holding the application ball 9 in a rollable manner. (Specifically, the annular rib 25a is fitted and held via the convex portion 29a, and the fitting cylinder 29 is connected to the inside of the fitting cylinder 29 and is annular toward the upper edge of the dome wall 25. And a support portion 33 formed of a support wall 31 on which the protrusion 31a is suspended.

  Then, between the support portion 33 and the holding wall 23, more specifically between the support wall 31 and the holding wall 23, the holding wall 23 together with the application ball 9 is disposed upward (dome wall 25) so as to be deformable. And a bend wall 35 that forms a fixed-quantity chamber R (see FIG. 2) capable of accommodating a fixed amount of content liquid between the holding wall 23 and the dome wall 25. Is provided. That is, when the application ball 9 is not pushed into the bend wall 35 (the state shown in FIG. 2), the holding wall 23 is separated from the dome wall 25 and the metering chamber R is formed between the holding wall 23 and the dome wall 25. On the other hand, in the state where the application ball 9 is pushed in (the state shown in FIG. 1), the holding wall 23 is displaced in the proximity direction with respect to the dome wall 25 by bending deformation.

  Furthermore, in this applicator 5, at least one (two in this case, formed at opposite positions) that causes the content liquid in the metering chamber R to flow out to the surface of the application ball 9 is poured into the holding wall 23. Holes 37 and 38 are formed. Note that the number of the pouring holes formed in the holding wall 23 may be three or more. In this case, the pouring holes are preferably arranged at equal intervals in the circumferential direction of the holding wall 23.

  Further, when the application ball 9 is pushed into the holding wall 23 against the urging force of the bend wall 35 (when the holding wall 23 is displaced in the proximity direction with respect to the dome wall 25), the communication hole 27 is provided. A cylindrical valve body 40 that is inserted into the inside and closes the communication hole 27 is integrally provided. In this example, the valve body 40 includes a base portion 40a that is in surface contact with the inner surface of the communication hole 27 when the application ball 9 is pushed in, and forms a seal between the inner surface and the base portion 40a toward the tip. It comprises a guide portion 40b that extends with a gap to the communication hole 27 and guides the movement of the valve body 40.

As shown in FIG. 1, the cap 7 has a top wall 42 and a side peripheral wall 44, and a pressing ring that presses the upper part of the application ball 9 when the cap 7 is tightened on the lower surface of the top wall 42. 42a are mounted on the inner periphery lower portion of the side wall 44, screw 44a to Rago in screws 3b ₁ formed on the outer periphery of the mouth portion 3b is formed.

  Next, the effect | action of the roll-on container 1 of this embodiment provided with the applicator 5 is demonstrated. In the container body 3, liquid or cream-like perfume, cosmetics, medicines, etc. are accommodated as an application, and is formed by attaching a holding member 13 fitted with an application ball 9 to the base member 11. The mounting cylinder 17 of the applicator 5 is aligned with the mouth portion 3b of the container body 3 and fitted with a stopper, and the cap 7 is attached to the mouth portion 3b of the container body 3 to hold the cap 7 The application ball 9 is pushed in by the ring 42 a and the communication hole 27 of the dome wall 25 is closed by the valve body 40 to form the roll-on container 1 in which the inside of the container body 3 is sealed.

  In use, as shown in FIG. 2, when the cap 7 is removed from the mouth 3 b of the container body 3, the holding wall 23 is pushed upward by the urging force of the bend wall 35, and the space between the holding wall 23 and the dome wall 25. Quantitative chamber R appears. In this state, as shown in FIG. 3 (a), when the roll-on container 1 is tilted or inverted, the container body passes through the gap between the communication hole 27 and the guide portion 40b of the valve body 40 in the fixed quantity chamber R. The content liquid in 3 flows in, and the fixed volume chamber R is filled with a certain amount of content liquid. At this time, since the space between the application ball 9 and the holding wall 23 is sealed at the tip position P of the holding wall 23, the content liquid in the fixed volume chamber R does not leak outside.

  From this state, as shown in FIG. 3 (b), when the application ball 9 is brought into contact with the application surface, the seal between the holding wall 23 and the application ball 9 is released, and as shown in FIG. 3 (c). When the application ball 9 is pressed against the application surface under a predetermined pressure, the base 40a of the valve body 40 is displaced as the holding wall 23 is displaced in the proximity of the dome wall 25 against the urging force of the bend wall 35. Is inserted into the communication hole 27 formed in the dome wall 25, the communication hole 27 is closed, and the application amount of the content liquid is determined. Then, when the roll-on container 1 is moved while pressing the application ball 9 against the application surface, the application ball 9 rotates, and the content liquid in the metering chamber R adheres to the surface of the application ball 9 through the extraction holes 37 and 38. The content liquid adhering to the surface of the application ball 9 is applied to the application surface.

  Therefore, according to the roll-on container 1 of the present embodiment, since the metering chamber R is formed between the holding member 13 and the base member 11, it is possible to apply a certain amount of content liquid, The fixed volume R appears by separating the holding wall 23 from the dome wall 25 with the urging force of the bend wall 35, and since the urging force is always constant, the capacity in the fixed volume R is also constant. Thus, it is possible to always apply a certain amount of the content liquid. Further, since the bend wall 35 for moving the holding wall 23 is formed integrally with the holding wall 23 and the support portion 33, the positioning work required when assembling the water-containing substance described in Patent Document 2 is performed. Assembling can be easily performed as unnecessary, and the number of parts can be reduced.

  In the present embodiment, the valve body 40 is formed with a base 40 a that forms a seal with the inner surface of the communication hole 27 when the application ball 9 is pushed in, and a gap is formed from the base 40 a to the communication hole 27. Since the guide portion 40b extends and guides the movement of the valve body 40, the guide portion 40b reliably inserts the valve body 40 into the communication hole 27 of the dome wall 25 when the application ball 9 is pushed. In other words, more than necessary content liquid can be prevented from flowing into the metering chamber R due to uncertain and unstable shut-off of the communication hole 27 by the valve body 40. A certain amount of content liquid can be reliably poured out and applied.

  Further, in the present embodiment, since the dispensing holes 37 and 38 are provided at two positions facing each other, the content liquid poured out from the metering chamber R can be uniformly attached to the application ball 9. Thus, the application of the content liquid by the application ball 9 can be performed without unevenness.

  Moreover, in the present embodiment, since the annular protrusion 31a that is pressed against the upper end edge of the dome wall 25 is provided on the lower surface of the support wall 31, the quantitative chamber R can be sealed by the annular protrusion 31a. When the application ball 9 is pressed against the application surface, the annular protrusion 31a is strongly pressed by the upper edge along with the bending deformation of the bend wall 35, so that the metering chamber R can be more securely sealed during application. Can do.

  Thus, according to the present invention, it is possible to propose a roll-on container that can always apply a certain amount of the content liquid and can be easily assembled.
