Measuring cap and container with measuring cap

Abstract

We propose a quantitative cap and a container with a quantitative cap that can inform the user when the granular material has been dispensed. [Solution] The quantitative cap 2 of the present invention is equipped with a repelling portion 3k that extends along the central axis O and is repelled by the discharge cylinder portion 4d when the discharge cylinder portion 4d is moved toward the opening portion 1c. When the container 1 is inverted and the discharge cylinder portion 4d is pressed against the object T, the closing wall portion 3c is displaced from the initial position to the tilted position, and the granular material R in the internal space N passes through the first passage opening H1 and is stored in a predetermined quantity between the second passage opening H2 and the first passage opening H1. Furthermore, the repelling portion 3k is repelled in the circumferential direction of the central axis O by the discharge cylinder portion 4d, and when the discharge cylinder portion 4d is moved away from the object T, the closing wall portion 3c is displaced from the tilted position to the initial position, and the stored granular material R passes through the second passage opening H2 and is discharged from the discharge opening 4e.

Description

Technical Field

[0001] The present invention relates to a metering cap capable of taking out a stored granular material quantitatively and a container with the metering cap.

Background Art

[0002] A metering cap capable of taking out a predetermined quantity of granular materials from a container storing granular materials such as confectionery and medicine, and a container with the metering cap are known (see, for example, Patent Document 1). When the head of such a container with a metering cap is pressed against the palm or the like, the regulating piece is displaced radially outward by a slide cylinder that moves toward the inside of the container body. As a result, the granular material in the container, whose progress was blocked by the regulating piece, moves into the measuring space. When the head is removed from the object, the slide cylinder moves back to its original position and the regulating piece returns, blocking the progress of new granular materials into the measuring space. Therefore, only a predetermined number of granular materials that moved into the measuring space when the head was pressed against the object are discharged onto the palm.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when taking out the granular material, if the pressing condition is insufficient when pressing the head of the above-mentioned container with the metering cap against the palm or the like, the slide cylinder may not move to the intended position, and there is a risk that the granular material cannot move into the measuring space while being blocked by the regulating piece. For this reason, there is a concern that the user may feel that the granular material cannot be taken out even though the slide cylinder is being moved.

[0005] In view of these points, the present invention aims to provide a quantitative cap and a container with a quantitative cap that can inform the user that the granular material has been dispensed. [Means for solving the problem]

[0006] The present invention relates to a quantitative cap that is attached to the mouth of a container and discharges a predetermined quantity of granular material contained in the internal space of the container, A discharge cylinder section having a cylindrical shape and an outlet at its tip for discharging the granular material, An elastic part that is elastically deformable in a direction along the central axis of the discharge cylinder and biases the discharge cylinder away from the opening when the discharge cylinder is moved toward the opening, Multiple closing wall portions are arranged around the central axis, each having a tip portion located near the central axis and a base portion located far from the central axis. When the discharge cylinder portion is moved toward the opening, the closing wall portion is pushed in by the discharge cylinder portion, elastically deformed, and displaced into a tilted position inclined around the base portion, while when the discharge cylinder portion is moved away from the opening, the closing wall portion displaces back to its initial position. A first passage opening is located between the internal space and the discharge opening, partitioned by a plurality of intermediate portions in the plurality of the closing wall portions, and is smaller than the outer diameter of the granular material when the closing wall portion is displaced to the initial position, and larger than the outer diameter of the granular material when the closing wall portion is displaced to the tilted position, A second passage opening is partitioned by a plurality of the tip portions of the plurality of the closing wall portions, located between the first passage opening and the discharge opening, and is larger than the outer diameter of the granular material when the closing wall portion is displaced to the initial position, and smaller than the outer diameter of the granular material when the closing wall portion is displaced to the tilted position, A repelling portion that extends along the central axis and is repelled by the discharge cylinder when the discharge cylinder is moved toward the opening, Equipped with, When the container is inverted and the discharge cylinder is pressed against the object, the repelling portion is repelled by the discharge cylinder in the circumferential direction of the central axis, and the closing wall portion is displaced from the initial position to the tilted position, causing the granular material in the internal space to pass through the first passage opening and be stored in a predetermined quantity between the second passage opening and the first passage opening. This is a quantitative cap in which, when the discharge pipe is moved away from the object, the closing wall is displaced from the tilted position to the initial position, and the stored granular material passes through the second passage opening and is discharged from the discharge opening.

[0007] According to the quantitative cap of the present invention, when the discharge cylinder is pressed against an object, the granular material contained in the internal space of the container is stored in a predetermined quantity between the second and first passage openings, and when the discharge cylinder is moved away from the object, only the stored granular material is discharged from the discharge opening. Furthermore, when the discharge cylinder is pressed against an object, the flicking part is flicked by the discharge cylinder, generating sound and vibration, so the user can know that the operation has been performed to a state where the granular material can be dispensed by the sound and vibration generated.

[Modes for carrying out the invention]

[0009] Hereinafter, an embodiment of the quantitative cap and container with the quantitative cap according to the present invention will be described with reference to the drawings. In this specification, the vertical direction refers to the direction along the central axis O shown in the figure (the central axis of the discharge cylinder portion 4d described later), and the terms "up" and "down" are used based on the upright position of the container with the quantitative cap shown in Figure 1. The radial direction is the direction perpendicular to the central axis O in a plane perpendicular to the central axis O, and the circumferential direction is the direction that circles around the central axis O in this plane.

[0010] As shown in FIG. 1, the container 100 with a metering cap according to the present embodiment is composed of a container 1, a metering cap 2, and an overcap 5. The metering cap 2 is composed of an inner stopper 3 and a head 4. As shown in the drawing, all these members are formed in a shape centered on the central axis O.

[0011] The container 1 includes a disc-shaped bottom portion 1a, a cylindrical body portion 1b connected to the outer edge portion of the bottom portion 1a, and a cylindrical mouth portion 1c having a smaller diameter than the body portion 1b and connected to the upper end portion of the body portion 1b. On the outer peripheral surface of the mouth portion 1c, a male screw portion 1d and an outward claw portion 1e are provided. An internal space N is defined inside the container 1, and granular matter R (see FIG. 6B) is accommodated in the internal space N. The granular matter R of the present embodiment is formed in a circular shape in a front view, and is formed in an elliptical shape as shown in FIG. 6B in a side view, although the illustration is omitted.

[0012] As shown in FIGS. 2A to 3B, the inner stopper 3 includes an annular base portion 3a centered on the central axis O. The base portion 3a of the present embodiment includes an annular plate-shaped portion extending in the horizontal direction and a cylindrical portion extending upward from the inner edge portion of the annular plate-shaped portion. On the lower surface of the annular plate-shaped portion, a cylindrical seal wall 3b extending downward is provided. The seal wall 3b is a portion that contacts the inner peripheral surface of the mouth portion 1c when the inner stopper 3 is attached to the container 1.

[0013] A plurality of closing wall portions 3c are provided on the inner side in the radial direction of the base portion 3a. The closing wall portions 3c are formed in a fan shape in a plan view. The inner stopper 3 in the present embodiment includes a total of five closing wall portions 3c. The aggregate of the five closing wall portions 3c is arranged at equal intervals around the central axis O (in the present embodiment, at intervals where the angle centered on the central axis O is 60°). Among the five closing wall portions 3c, the end closing wall portions 3c are arranged at intervals where the angle centered on the central axis O is relatively large (in the present embodiment, at intervals of 120°), forming a gap. An elastic portion 3k described later is arranged in this gap.

[0014] Furthermore, the closed wall portion 3c is shaped to include an inner vertical plate wall 3d extending vertically inward in the radial direction, an inclined wall 3e that curves downward and slopes radially outward from the lower end of the inner vertical plate wall 3d, an outer vertical plate wall 3f extending upward from the outer edge of the inclined wall 3e, and a horizontal plate wall 3g extending radially outward from the upper end of the outer vertical plate wall 3f. A protrusion 3h projecting radially inward is provided at the point where the inner vertical plate wall 3d and the inclined wall 3e are connected, and a rib 3j connecting the inner vertical plate wall 3d, the inclined wall 3e, and the outer vertical plate wall 3f is provided on the upper surface of the inclined wall 3e. The part of the closed wall portion 3c where the inner vertical plate wall 3d is provided corresponds to the "tip portion" in this specification, the part where the horizontal plate wall 3g is provided corresponds to the "root portion" in this specification, and the part where the protrusion 3h is provided corresponds to the "intermediate portion" in this specification. The closing wall portion 3c is cantilevered to the base portion 3a by connecting the horizontal plate wall 3g to the cylindrical portion of the base portion 3a.

[0015] The closure wall 3c is normally in the initial position shown in Figures 3A and 3B. However, when the rib 3j is pressed, the part where the horizontal plate wall 3g connects to the base 3a undergoes elastic deformation, causing it to tilt and move around this connecting part, displacing it into a tilted position (see Figures 7A and 7B). Here, the opening that is partitioned by multiple protrusions 3h in the multiple closure wall 3c and forms a circular shape in plan view is called the first passage opening H1, and the opening that is partitioned by the tips of multiple inner vertical plate walls 3d in the multiple closure wall 3c and forms a circular shape in plan view is called the second passage opening H2. When the closure wall 3c is in the initial position, the diameter of the first passage opening H1 is smaller than the diameter of the granular material R (the circular diameter in plan view), and the diameter of the second passage opening H2 is larger than the diameter of the granular material R. Furthermore, when the occluding wall 3c is in a tilted position, the diameter of the first passage opening H1 is larger than the diameter of the granular material R, and the diameter of the second passage opening H2 is smaller than the diameter of the granular material R.

[0016] The inner plug 3 is also equipped with a retractable portion 3k. The retractable portion 3k extends along the central axis O. The retractable portion 3k extends from the lower end of the closing wall portion 3c toward the tip (i.e., the portion where the inner vertical plate wall 3d is provided), and as it approaches the tip, it extends inclined toward one of the adjacent closing wall portions 3c in the circumferential direction. In addition, as shown in Figures 2A and 3A, the retractable portion 3k has a contact surface 3m formed at its tip that is parallel to the central axis O. In this embodiment, one retractable portion 3k is provided and is positioned in the center of the gap between the closing wall portions 3c at the ends of the five closing wall portions 3c. That is, the retractable portion 3k and the closing wall portion 3c adjacent to the retractable portion 3k are positioned such that the angle with respect to the central axis O is 60°.

[0017] The retractable portion 3k is connected to the closing wall portion 3c at its base end and is elastically deformable in the circumferential direction starting from the connected portion. As shown in Figures 2A and 3B, the tip of the retractable portion 3k is provided with an extended portion 3n that protrudes so as to abut against the head 4 (a projection 4m provided on the discharge cylinder portion 4d, which will be described later) (see Figure 6B). In this embodiment, the extended portion 3n protrudes radially outward. The extended portion 3n is the part that abuts against the discharge cylinder portion 4d from the initial position of the closing wall portion 3c to the tilted position of the closing wall portion 3c (see Figures 6A to 8B).

[0018] As shown in Figures 4A to 5B, the head 4 comprises an annular cylindrical wall 4a centered on a central axis O, and an annular upper wall 4b extending radially inward from the upper end of the cylindrical wall 4a. The cylindrical wall 4a surrounds the upper part of the opening 1c. An inward-facing claw portion 4c is provided on the inner circumferential surface of the cylindrical wall 4a, and the head 4 can be attached to the opening 1c by engaging the inward-facing claw portion 4c with the outward-facing claw portion 1e. The cylindrical wall 4a, the upper wall 4b, and the inward-facing claw portion 4c correspond to the "attachment portion" in this specification. When the head 4 is attached to the opening 1c, the annular plate-shaped portion of the base 3a is sandwiched between the opening 1c and the upper wall 4b, so that the inner plug 3 can be held in the opening 1c.

[0019] The head 4 also includes a cylindrical discharge pipe section 4d located radially outward from the inner vertical plate wall 3d. As shown in Figures 4A to 5B, an outlet 4e for discharging granular material R is provided on the inner circumference of the upper part of the discharge pipe section 4d. A guide section 4f is formed on the inner circumference of the lower part of the discharge pipe section 4d at a position facing the ejection section 3k.

[0020] As shown in Figures 4B to 5B, the guide section 4f has a recess 4h formed on the inner circumferential surface of the discharge pipe section 4d. The recess 4h is rectangular in shape when viewed from the central axis O and has a pair of side walls 4j facing each other in the circumferential direction and a bottom wall 4k connecting the pair of side walls 4j. One side wall 4j is provided with a projection 4m that protrudes from the bottom wall 4k toward the other side wall 4j. The projection 4m is connected to one side wall 4j and the bottom wall 4k below the center in the vertical direction of the recess 4h. The outer edge of the projection 4m has a shape that tapers away from the discharge port 4e, and in this embodiment, it becomes rounded so as it moves away from the discharge port 4e it approaches one side wall 4j. Note that the tapering shape of the outer edge of the projection 4m is not limited to a rounded shape, and may be an inclined surface, etc.

[0021] Furthermore, the head 4 is equipped with an elastic part 4g that connects the radially inner end of the upper wall 4b to the vertically intermediate portion of the discharge cylinder portion 4d. The elastic part 4g in this embodiment is a curved plate that bulges out to form a dome shape, as shown in the figure, and is elastically deformable in a direction along the central axis O. Therefore, the discharge cylinder portion 4d connected to the elastic part 4g can move along the central axis O. Also, when the discharge cylinder portion 4d is moved toward the opening portion 1c (towards the cylindrical wall 4a), the discharge cylinder portion 4d is biased toward the opening portion 1c by the elastic part 4g.

[0022] As shown in Figure 1, the overcap 5 has a lidded cylindrical shape and includes a top wall 5a that extends radially outward from its lower end, and an outer peripheral wall 5b that extends downward from the outer edge of the lower end of the top wall 5a and surrounds the cylindrical wall 4a and the opening 1c. The inner circumferential surface of the outer peripheral wall 5b is provided with a female threaded portion 5c, and the overcap 5 is attached to the opening 1c by screwing the female threaded portion 5c onto the male threaded portion 1d. The overcap 5 also has a rod-shaped portion 5d that extends downward from the lower surface of the top wall 5a.

[0023] To discharge granular material R from the container 100 with a quantitative cap in this configuration, the overcap 5 shown in Figure 1 is removed from the opening 1c. Then, the container 1 is inverted, and the discharge cylinder 4d is brought into contact with the object T from which the granular material R is to be removed (for example, the palm of the hand), as shown in Figures 6A and 6B. Note that the blocking wall 3c shown in Figures 6A and 6B is in its initial position. That is, since the diameter of the first passage opening H1 is smaller than the diameter of the granular material R, the granular material R contained in the internal space N cannot pass through the first passage opening H1 due to the blocking wall 3c.

[0024] Then, as shown in Figures 7A and 7B, when the container 1 is pressed against the object T, the discharge pipe portion 4d moves toward the opening portion 1c due to the object T. At this time, the lower part of the discharge pipe portion 4d contacts and presses against the rib 3j, so the closing wall portion 3c, which was in the initial position, is displaced to a tilted position. When the closing wall portion 3c is displaced to a tilted position, the diameter of the first passage opening H1 becomes larger than the diameter of the granular material R, so the granular material R contained in the internal space N passes through the first passage opening H1. On the other hand, when the closing wall portion 3c is displaced to a tilted position, the diameter of the second passage opening H2 becomes smaller than the diameter of the granular material R, so a predetermined quantity (1 in this embodiment) of the granular material R is stored between the second passage opening H2 and the first passage opening H1. In this state, the elastic portion 4g is elastically deformed as shown in the figure.

[0025] As shown in Figure 6B, the expanded portion 3n of the aforementioned repulsion portion 3k is in contact with the lower part of the projection 4m of the guide portion 4f in the discharge cylinder portion 4d (the side opposite to the discharge port 4e) before the container 1 is pressed against the object T. When the container 1 is pressed against the object T and the discharge cylinder portion 4d moves toward the opening portion 1c, the projection 4m causes the repulsion portion 3k to bend circumferentially (towards the side wall 4j on the side where the projection 4m is not provided in Figure 6A) along the outer edge of the projection 4m. As the discharge cylinder portion 4d moves further, the expanded portion 3n goes over the projection 4m, and as shown in Figures 7A and 7B, the bent repulsion portion 3k returns to its original shape, and the contact surface 3m abuts against one of the side walls 4j at the upper part of the projection 4m (the side facing the discharge port 4e). In other words, when the discharge cylinder 4d moves toward the opening 1c and the closing wall 3c, which is in its initial position, is displaced to a tilted position, the repelling part 3k is repelled circumferentially by the guide part 4f so as to overcome the projection 4m, causing the contact surface 3m to come into contact with the side wall 4j, and sound and vibration are generated at that time. As a result, the user of the container with a quantitative cap 100 can know that the granular material R has been processed to a state where it can be dispensed by the sound and vibration generated. Furthermore, in this embodiment, the contact surface 3m abuts against the side wall 4j of the recess 4h formed on the inner circumferential surface of the discharge cylinder 4d, so that the sound and vibration transmitted to the user can be made even louder.

[0026] Subsequently, when the force pressing the container 1 toward the object T is released, the discharge cylinder portion 4d moves away from the opening portion 1c due to the restoring force of the elastic portion 4g, as shown in Figures 8A and 8B. As a result, the elastically deformed closing wall portion 3c is displaced from its tilted position back to its initial position, preventing the granular material R contained in the internal space N from passing through the first passage opening H1 again. Therefore, when the container 1 is lifted away from the object T, only the single granular material R that was stored between the second passage opening H2 and the first passage opening H1 is discharged from the discharge opening 4e.

[0027] By the way, when the discharge pipe section 4d moves away from the opening section 1c from the state shown in Figures 7A and 7B, the recoil section 3k is flexed in the circumferential direction so that the projection 4m returns along its outer edge. At this time, if the restoring force of the elastic section 4g is not very large, the projection 4m may get caught on the expanded section 3n of the recoil section 3k, causing the discharge pipe section 4d to stop midway. In this embodiment, the outer edge of the projection 4m has a shape that tapers away from the discharge opening 4e. As a result, when the discharge pipe section 4d moves away from the opening section 1c, the expanded section 3n slides along the outer edge of the projection 4m and returns to its original position, thus suppressing the occurrence of such problems.

[0028] Although one embodiment of the present invention has been described above, the present invention is not limited to such specific embodiments, and unless otherwise specifically limited in the above description, various modifications and changes are possible within the scope of the spirit of the present invention as described in the claims. For example, the configurations of the embodiments described above can be added or deleted as appropriate, and the configuration of one embodiment can be provided in other embodiments. Furthermore, the effects in the embodiments described above are merely illustrative of the effects that may arise from the present invention, and do not mean that the effects of the present invention are limited to the effects described above.

[0029] For example, the number of discharge pipes 4d and ejection sections 3k is just one example and is not limited to the embodiments described above.

[0030] Furthermore, the function of returning the discharge cylinder portion 4d to its initial position by the elastic portion 4g may be achieved by a separate component (for example, a metal coil spring) from the head 4. When a coil spring is used, a large elastic force can generally be obtained, so even if the number of spring portions 3k is increased further, the pushed-in discharge cylinder portion 4d can be reliably returned to its initial position.

[0031] Furthermore, the quantity of granular material R to be discharged is not limited to one; it can be set to two or more. To increase the quantity of granular material R, for example, the length of the inner vertical plate wall 3d in the closure wall section 3c can be extended, thereby increasing the distance between the second passage opening H2 and the first passage opening H1.

[0032] Furthermore, the retractable portion 3k is not limited to being inclined with respect to the central axis O, but may also extend parallel to the central axis O.

[0033] Furthermore, the configuration of the guide portion 4f is not limited to the example in which a recess 4h and a projection 4m are formed on the inner circumferential surface of the discharge pipe portion 4d, but may also be formed to protrude from the inner circumferential surface of the discharge pipe portion 4d.

[0034] (Note) This specification discloses the following technologies in one aspect. The reference numerals listed below correspond to those used in the accompanying drawings, but are provided as examples only and are not intended to limit the inventions of this application.

[0035] (Technology 1) A quantitative cap (2) is attached to the mouth (1c) of a container (1) and discharges a predetermined quantity of granular material (R) contained in the internal space (N) of the container (1), A discharge cylinder section (4d) which is cylindrical and has a discharge port (4e) at its tip for discharging the granular material (R), An elastic part (4g) is elastically deformable in a direction along the central axis (O) of the discharge cylinder portion (4d), and when the discharge cylinder portion (4d) is moved toward the opening portion (1c), the elastic part (4g) biases the discharge cylinder portion (4d) toward the opening portion (1c), Multiple closing wall portions (3c) are arranged around the central axis (O), and each portion has a tip located near the central axis (O) and a base located far from the central axis (O). When the discharge cylinder portion (4d) is moved toward the opening portion (1c), the closing wall portion (3c) is pushed in by the discharge cylinder portion (4d) and elastically deforms, displacing into a tilted position inclined around the base portion, while when the discharge cylinder portion (4d) moves away from the opening portion (1c), the closing wall portion (3c) displaces back to its initial position. A first passage opening (H1) is partitioned by multiple intermediate portions in the multiple closing wall portions (3c), located between the internal space (N) and the discharge port (4e), and is smaller than the outer diameter of the granular material (R) when the closing wall portion (3c) is displaced to the initial position, and larger than the outer diameter of the granular material (R) when the closing wall portion (3c) is displaced to the tilted position, A second passage opening (H2) is partitioned by a plurality of tip portions in a plurality of the closing wall portions (3c), located between the first passage opening (H1) and the discharge opening (4e), and is larger than the outer diameter of the granular material (R) when the closing wall portion (3c) is displaced to the initial position, and smaller than the outer diameter of the granular material (R) when the closing wall portion (3c) is displaced to the tilted position, A repelling portion (3k) extends along the central axis (O) and is repelled by the discharge cylinder portion (4d) when the discharge cylinder portion (4d) is moved toward the opening portion (1c), Equipped with, When the container (1) is inverted and the discharge cylinder portion (4d) is pressed against the object (T), the repelling portion (3k) is repelled by the discharge cylinder portion (4d) in the circumferential direction of the central axis (O), and the closing wall portion (3c) is displaced from the initial position to the tilted position, and the granular material (R) in the internal space (N) passes through the first passage opening (H1) and is stored in a predetermined quantity between the second passage opening (H2) and the first passage opening (H1). A quantitative cap (2) wherein when the discharge pipe portion (4d) is moved away from the object (T), the closing wall portion (3c) is displaced from the tilted position to the initial position, and the stored granular material (R) passes through the second passage opening (H2) and is discharged from the discharge opening (4e).

[0036] According to this technology, when the discharge cylinder (4d) is pressed against the object (T), a predetermined amount of granular material (R) contained in the internal space (N) of the container (1) is stored between the second passage opening (H2) and the first passage opening (H1). When the discharge cylinder (4d) is moved away from the object (T), only the stored granular material (R) is discharged from the discharge opening (4e). Furthermore, when the discharge cylinder (4d) is pressed against the object (T), the flicking part (3k) is flicked by the discharge cylinder (4d), generating sound and vibration, so the user can know that the granular material (R) has been processed to a state where it can be removed by the sound and vibration produced.

[0037] However, in a configuration where the flicking portion (3k) extends radially, if the flicking portion (3k) is to generate a sufficiently loud sound or vibration, the length of the flicking portion (3k) must be increased radially, which may necessitate changes to the radial size of other components or the entire cap. In contrast, with the quantitative cap (2) of the present invention, the flicking portion (3k) extending along the central axis (O) is flicked in the circumferential direction, so the length of the flicking portion (3k) can be increased regardless of the radial size of other components. Therefore, it is easier to realize a configuration that generates sufficient sound and vibration when flicked.

[0038] (Technology 2) The quantitative cap (2) is composed of an inner stopper (3), The inner plug (3) has a plurality of closing wall portions (3c), a first passage opening (H1), a second passage opening (H2), a retracting portion (3k), and an annular base portion (3a) centered on the central axis (O). The multiple closing wall portions (3c) are connected to the base portion (3a) at intervals around the central axis (O), The quantitative cap (2) according to Technical 1, wherein the repulsive portion (3k) is connected to the base portion (3a) between the circumferentially spaced closing wall portions (3c), and extends in an inclined direction from the lower end of the closing wall portion (3c) toward the tip portion, approaching one of the adjacent closing wall portions (3c).
