  Although the said application | coating container is the outstanding thing which can apply | coat a fixed quantity liquid easily, the procedure until application | coating is a little complicated. For example, in the application container, first, the cap body is removed from the housing, and the position of the operation body is confirmed and brought into a measurement state. Next, the container is turned upside down to confirm that the chemical solution is filled in the measurement chamber. Next, return the container to the top and wait for a few seconds, and check that the excess amount of the chemical solution returns to the housing and the water level of the chemical solution reaches the measuring line position. Then, the operating body is turned into a pouring state, and the container is turned upside down again to apply the spout with the spout of the operating body facing the scalp. After use, return the operating body to the weighing state so that it does not flow from the chemical solution or the operating body through the spout, and store with the cap closed.

  The present invention has been made in view of the above points, and proposes an application container that can apply a fixed amount of liquid by an extremely simple operation and has a simple structure.

  The application container of the present invention includes a container body and an application stopper, and as a form of the container body, a bottle-type container in which the mouth and neck part is erected from the cylindrical body part through the shoulder part can be preferably used. Not limited to this.

  The application plug is attached to the container body by being fitted to the mouth and neck, and is provided with a valve body at the distal end portion that allows the inside and outside to communicate with each other by being pushed in, and can be tilted and always biased upright when tilted. And a supported nozzle. As a means for fitting the coating plug to the mouth and neck, a mounting cylinder is used which is fitted on the outer circumference of the mouth and neck by means of screwing or mutual locking means. Further, as a means for supporting the nozzle as described above, an elastic elastic leg having a base end extending in a liquid-tight manner in the mounting cylinder is provided from the lower outer periphery of the nozzle, and the lower end of the nozzle is provided. Is supported in liquid-tight contact with the upper surface of the lid plate. A clearance that allows the nozzle to be tilted is provided on the outer periphery of the nozzle.

  When the nozzle is upright, the elastic annular leg and the nozzle base end block the through hole to block the inside of the container from the inside of the nozzle, and tilt the nozzle to separate the lower end surface of the nozzle from the upper surface of the lid plate. Thus, the through hole and the inside of the nozzle are communicated, and thus the inside of the nozzle in the container body is communicated.

  Further, when the nozzle is tilted, an operation projection is provided so that the gap between the nozzle lower end and the cover plate can be made larger and the liquid can flow in quickly. This operation protrusion has a sliding surface on the lower surface, and is configured to slide up the flange inner peripheral edge of the mounting cylinder on the tilt side. The operation protrusion may be provided annularly over the entire outer periphery of the nozzle, or may be a discontinuous protrusion shape. Although it is not necessary to specify the exact position of the projecting protrusion, even if there is a slight deviation to the extent that the upper part of the sliding surface is located at the upper edge of the inner peripheral edge of the flange of the mounting cylinder in order to exert the above effect good. The specific shape of the sliding surface a may be a tapered surface, a rounded surface, or any other surface that gradually increases in diameter as it rises.

  In the present invention, an elastic member such as a coil spring is interposed between the upper surface of the elastic annular leg and the lower surface of the flange so that the elastic annular leg is constantly biased downward to reinforce the elastic restoring force of the elastic annular leg. It is configured as shown. As a material for forming the coating plug, a synthetic resin is mainly used, and an elastomer or a metal is used in combination as necessary. For example, the elastomer may be applied to a portion requiring elasticity, and the metal may be applied to a coil spring.

As a first means for solving the above-mentioned problems, the container body A and the coating plug B fitted to the container body A are fitted, and the coating plug B is fitted to the outer periphery of the mouth neck portion 4 of the container body A. And a mounting cylinder 10 having a flange 15 projecting inward from the top, a lid 11 having a through hole 21 at an eccentric position, closing the mouth neck 4 of the container body A, and a lower outer periphery The lower end is in fluid-tight contact with the upper surface of the lid plate 11 inside the through-hole 21 so that the base end can be tilted by the elastic annular leg 23 connected to the mounting cylinder 10 outside the through-hole 21 by extending the base end. The nozzle 12 is supported, and the discharge port 22 of the nozzle 12 protrudes so as to be pushed in an upward biased state, and the valve body 13 communicates the inside and the outside by being pushed. Thus, the container body A and the nozzle 12 are configured to communicate with each other, and an operation protrusion 24 whose lower surface forms a sliding surface a is provided on the outer periphery of the nozzle 12 so as to protrude from the nozzle 12. The flange 15 of the inner peripheral edge portions of the inclined side as configuration the sliding surface rises slides during leaning interposed coil spring 31 between the elastic annular legs 23 top flange 15 bottom surface which projects from the hollow mounting 10 Thus, the elastic annular leg 23 was always urged downward.

As a second means, it comprises a container body A and a coating plug B fitted to the container body A. The coating plug B is fitted to the outer periphery of the mouth neck 4 of the container body A, and from the upper part. Mounting cylinder 10 having a flange 15 projecting in the direction, the mouth and neck portion 4 of the container body A, a lid plate 11 having a through hole 21 at an eccentric position, and a base end extending from the lower outer periphery A nozzle 12 whose part is tiltable by an elastic annular leg 23 connected to the mounting cylinder 10 outside the through-hole 21 and whose lower end is supported in liquid-tight contact with the upper surface of the lid plate 11 inside the through-hole 21; 12 is provided with a valve body 13 projecting so as to be able to be pushed into the discharge port 22 in an upward biased state and communicating with the inside and outside by being pushed, and the lower end surface of the nozzle 12 is separated from the top surface of the cover plate 11 by tilting and The nozzle 12 is configured so as to communicate with the inside of the nozzle 12, and a coil spring 31 is interposed between the lower surface of the flange 15 and the upper surface of the elastic annular leg 23 so as to be always elastic. 23 were forced downward.

As a third means, in the first means or the second means, a fitting protrusion 20 into which the lower end portion of the nozzle 12 is fitted inside the through hole 21 of the cover plate 11 is projected. Set up.

  The application container according to the present invention presses and tilts the nozzle 12 in a state where the container is inverted, and then the nozzle 12 automatically returns to the upright position when the container is upright by releasing the press. A predetermined amount of liquid is weighed. Then, if the valve body 13 at the tip of the nozzle 12 is pressed against the scalp as the application portion, a fixed amount of liquid can be applied. Therefore, the operation is very simple.

  In addition, in the case where the operation protrusion 24 whose lower surface forms a sliding surface on the outer periphery of the nozzle 12 is provided, the lower end surface of the nozzle 12 can be greatly separated from the upper surface of the cover plate 11 when the nozzle 12 is tilted. The flow path from the hole 21 into the nozzle 12 can be made larger, and a quick and more reliable weighing operation can be performed.

  In addition, when the coil spring 31 is interposed between the lower surface of the flange 15 and the upper surface of the elastic annular leg 23 and the elastic annular leg 23 is constantly urged downward, together with the elastic restoring force of the elastic annular leg 23, The nozzle 12 can be reliably returned to its original state after being tilted, and the sealing performance at the lower end of the nozzle 12 can be sufficiently maintained even in repeated use, and the durability is excellent.

  In addition, the application plug B has an advantage that the number of members, for example, the mounting cylinder 10, the cover plate 11, the nozzle 12, and the valve body 13 is extremely small, and the manufacture is easy and inexpensive.

  In addition, if the fitting protrusion 20 that fits the lower end of the nozzle 12 is provided inside the through hole 21 of the cover plate 11, the nozzle 12 always returns to the proper position, and as a result, the elastic annular leg 23 is restored to the original position. Thus, it is possible to reliably return to the shape and prevent the inconvenience such as deformation of the elastic annular leg 23 as much as possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The drawing shows an example of the coating container of the present invention, and the coating container 1 includes a container body A, a coating plug B, and a cap C.

  The container body A is formed of a synthetic resin, and the mouth and neck portion 4 is erected from the upper end of the cylindrical body portion 2 via the shoulder portion 3. An annular recess 5 for fitting the lower end edge of the cap C is provided in the periphery of the shoulder 3. In addition, a locking protrusion 6 for locking the application plug B is provided around the outer periphery of the mouth and neck portion 4.

  The coating plug B includes a mounting cylinder 10, a lid plate 11, a nozzle 12, and a valve body 13.

  The mounting cylinder 10 is for fitting the coating plug B to the container body A by fitting it to the outer periphery of the mouth and neck portion 4 of the container body A. The engaged ridge 14 is provided around to prevent it from coming out upward. A flange 15 extends inward from the upper edge of the mounting cylinder 10. Further, a downward step 16 is formed on the inner peripheral upper portion of the mounting cylinder 10, and a locking ridge 17 is provided around the predetermined position below it.

  The cover plate 11 is fitted with a peripheral edge at the upper part of the inner periphery of the mounting cylinder 10 at a distance from the flange 15, and the seal cylinder 18 suspended at a predetermined position on the lower peripheral part of the bottom surface is tightly attached to the inner periphery of the mouth neck 4. The liquid-tightness of this part is aimed at by making it fit. On the upper surface of the peripheral edge portion of the lid plate 11, a double cylindrical sandwiching portion 19 for tightly fixing an elastic annular leg to be described later is provided. Then, the outer peripheral edge of the mounting cylinder 10 is moved over the inner surface of the mounting cylinder 10 so as to overcome the locking protrusion 17 of the mounting cylinder 10, and the locking protrusion 17 prevents the drop off downward. The center part of the cover plate 11 bulges upward in a circular shape, and a fitting protrusion 20 is provided on the upper surface to which the lower end of the nozzle 12 is fitted. The outer peripheral surface of the fitting protrusion 20 is formed into a tapered surface. In addition, a through hole 21 is formed at an eccentric position of the lid plate 11 outside the fitting protrusion 20. A pair of left and right through holes 21 are formed.

  The nozzle 12 has a cylindrical shape in which the lower end of the inner periphery is fitted to the fitting protrusion 20 and the diameter-reduced portion of the upper end is formed in the discharge port 22, and can be tilted between the inner peripheral edge of the flange 15 and the outer surface of the cylindrical wall. Clear gaps are provided. Further, an elastic elastic leg 23 is extended from the lower end of the outer periphery of the nozzle 12. This elastic annular leg 23 has a bulging portion that extends horizontally outward and has an inverted U-shaped cross section at the peripheral edge, and further has an outer peripheral end that is bifurcated to provide a gap between the clamping portion 19 and the clamping portion. The base end portion is tightly fitted and fixed between the upper surface 19 and the downward stepped portion 16, and the lower end of the nozzle 12 is in liquid-tight contact with the lid plate 11. When the nozzle 12 is tilted, the bulging portion mainly extends so that the nozzle 12 can be easily tilted, and when the nozzle 12 is released from tilting, the nozzle 12 is returned to its original state by an elastic restoring force.

  An operation protrusion 24 is formed in an annular shape at the position of the flange 15 on the outer periphery of the nozzle 12 so as to form a sliding surface a having a tapered lower surface.

  The valve body 13 has a cylindrical shape with its lower end expanded in a flange shape, and closes the discharge port 22 by pressing the tapered portion of the upper surface of the flange portion against the inner surface of the nozzle 12 continuing to the discharge port 22. The lower end of the valve body 13 is integrally connected with the upper end of a spiral spring 25 made of a synthetic resin having a base end portion fitted and fixed to the inner peripheral vertical direction middle portion of the nozzle 12 to constantly bias the valve body 13 upward. I am letting. In addition, a concave groove 26 that is lowered from the upper end to a predetermined position is formed in the outer surface of the valve body 13, and when the valve body 13 is pushed into the discharge port 22 by pressing the protruding portion, the concave groove 26 is interposed. Thus, the inside and outside of the nozzle 12 are configured to communicate with each other.

  The cap C is attached by fitting the lower end portion of the peripheral wall 27 to the annular recess 5, and the downward stepped portion on the lower surface is fitted to the upper end of the nozzle 12 from the back surface of the top wall 28 extending from the upper end edge of the peripheral wall 27. The fitting cylinder 29 to be worn is suspended.

  When the coating container 1 configured as described above is used, the cap C is removed from the state shown in FIG. 1, and the container 12 is inverted and the nozzle 12 is pressed and tilted as shown in FIG. At this time, the lower end surface of the nozzle 12 is separated from the upper surface of the cover plate 11, and the liquid in the container body A flows into the nozzle 12 through the through hole 21. When the nozzle 12 is tilted, as shown in FIG. 4, the tilted sliding surface a slides up the inner peripheral edge of the flange 15 of the mounting cylinder 10, and the nozzle 12 has a larger separation distance from the cover plate 11. The bottom surface of the nozzle 12 is all separated from the top surface of the cover plate 11. Next, when the pressure of the nozzle 12 is released, the nozzle 12 returns to the original state by the elastic restoring force of the elastic annular leg 23, the container A and the nozzle 12 are shut off, and a predetermined amount is stored in the nozzle 12. The liquid is weighed. Next, as shown in FIG. 3, by pressing the valve body 13 against the surface to be coated of the head 30, the liquid in the nozzle 12 is discharged to the surface to be coated through the concave groove 26.

  5 to 7 show other examples. In this example, in the example of FIG. 1, the elastic annular leg 23 is formed by interposing a metal coil spring 31 between the flange 15 and the elastic annular leg 23. Always pressed downward. Other configurations are the same as those in the example of FIG.

  In this case, the cap C is removed from the state shown in FIG. 5, and the container is inverted and the nozzle 12 is pressed and tilted as shown in FIG. At this time, the lower end surface of the nozzle 12 is separated from the upper surface of the cover plate 11, and the liquid in the container body A flows into the nozzle 12 through the through hole 21. When the nozzle 12 is tilted, the sliding surface a on the tilting side slides and rises on the inner peripheral edge of the flange 15 of the mounting cylinder 10 to increase the separation distance of the nozzle 12 from the cover plate 11. Are all separated from the upper surface of the cover plate 11. Next, if the pressure of the nozzle 12 is released, the nozzle 12 returns to the original state by the elastic restoring force of the elastic annular leg 23 and the elastic restoring force of the coil spring 31, and the inside of the container body A and the inside of the nozzle 12 are shut off. A predetermined amount of liquid is measured in the nozzle 12. Next, as shown in FIG. 7, by pressing the valve body 13 against the surface to be coated of the head 30, the liquid in the nozzle 12 is discharged to the surface to be coated through the concave groove 26. In this case, the elastic annular leg 23 functions sufficiently by the coil spring 31 even if the lower end of the nozzle 12 is not necessarily in pressure contact with the cover plate 11.

  FIG. 8 shows another case, which is the same as the example of FIG. 5 except that the operation protrusion 24 is not provided, and the same reference numerals are given and description thereof is omitted. In this case, since there is no operation protrusion 24, when the nozzle 12 is tilted, the opening at the lower end of the nozzle is smaller than that with the operation protrusion 24, but the measurement and application of the content liquid are good.
