Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the dispensing cap described in Patent Document 1 has a problem in that it is necessary to provide a dispensing port and an arbitrary amount dispensing port, and to provide lid members for closing these ports respectively.

[0005] An object of the present invention is to create a dispensing cap that can switch between dispensing and arbitrary amount dispensing and discharge from one discharge port in order to solve the above problems in the prior art.

Means for Solving the Problems

[0006] Among the means for solving the above problems, the main means of the present invention is a dispensing cap configured to include a cap body attached and fixed to the mouth of a container body in which the content is stored, a lid member including a dispensing port for discharging the content and an opening / closing lid provided so as to be able to close the dispensing port, and a metering member for metering the content. The lid member and the metering member are assembled to be rotatable in the circumferential direction with respect to the cap body in an integrated state. By rotating the lid member in the forward or reverse direction, it is possible to switch to a fixed-dose dispensing state in which a fixed amount is discharged or an arbitrary dispensing state in which continuous discharge is possible, which is characterized by this. In the main means of the present invention, by rotating the lid member in one or the other direction in the circumferential direction, it is possible to switch to the fixed-dose dispensing state or the arbitrary dispensing state, so that the fixed-dose dispensing operation or the arbitrary dispensing operation can be easily performed.

[0007] As a more specific configuration, The cap body has an outer cylinder portion screwed to the mouth portion, an inner cylinder portion continuously provided inside the outer cylinder portion, a bottom wall portion of a predetermined shape continuously provided at the lower end of the inner cylinder portion to form a temporary storage chamber, and a metering region where the bottom wall portion is provided inside the inner cylinder portion and an opening region forming a region other than the metering region. The lid member has, on the inner surface of the top wall portion, a partition plate provided to hang down and a pair of partition ribs projecting in an L-shape in plan view and arranged with a predetermined interval in the radial direction. The metering member is formed having an inclined portion and a partition plate standing at an end of the inclined portion and having a notch hole at its upper end and extending to a position in contact with the inner surface of the top wall portion of the lid member. By arranging the partition plate inside the metering member, the inside of the metering member is partitioned into two spaces in the front and rear. Of the two spaces in the front and rear, one has a first metering chamber provided in one of the vertical directions for metering the content and a second metering chamber provided in the other of the vertical directions and following the first metering chamber, and is provided between the partition plate and the partition plate, and the other is a communication space provided between the partition plate and the temporary storage chamber. The temporary storage chamber is communicated through a gap formed at a portion where the lower end of the partition plate and the inclined portion face each other, and the opening region and the first metering chamber are communicated through the notch hole that restricts the movement of the content.

[0008] Another means of the present invention is adding to any of the above means the means that the first measurement chamber is defined by the short-side ribs of the pair of partition ribs, the partition plate, and the partition board. In the above means, in the quantitative dispensing operation, the discharged content can be set to a fixed amount.

[0009] Another means of the present invention is adding to any of the above means the means that the measuring member is provided with a pair of left and right clamping walls that clamp the partition board from the front and rear directions. In the above means, by clamping the partition board with the pair of left and right clamping walls, damage to the partition board during impact can be prevented.

Advantages of the Invention

[0010] In the present invention, since the number of the dispensing ports and the opening / closing lids can be minimized, the structure of the dispensing cap can be simplified.

[0014] As shown in FIG. 1, the dispensing cap 1 of the present invention includes a cap body 10 attached to the mouth portion 51 of the container body 50, a lid member 20 assembled to the upper portion of the cap body 10, and a measuring member 30 disposed within the cap body 10, all of which are formed of a predetermined synthetic resin material.

[0015] As shown in FIG. 2, the cap body 10 is a double-cylindrical member having a cylindrical outer cylinder portion 11 and an inner cylinder portion 12 concentric with the cap axis O, and is configured such that the mouth portion 51 can be inserted into the gap where the outer cylinder portion 11 and the inner cylinder portion 12 face each other in the radial direction. In addition, an internal thread 11a that engages with an external thread 52 (see FIG. 1) formed on the outer peripheral surface of the mouth portion 51 is formed on the inner peripheral surface of the outer cylinder portion 11, and an alignment mark 11b is engraved or formed by means such as printing on the outer peripheral surface of the outer cylinder portion 11 (see FIG. 2(c)).

[0016] A ring-shaped connecting portion 14 that connects the outer cylinder portion 11 and the inner cylinder portion 12 is formed at the upper portions of the outer cylinder portion 11 and the inner cylinder portion 12, and a short cylindrical discharge cylinder portion 15 stands upright on the upper surface of this ring-shaped connecting portion 14. An engaged portion 15a that protrudes in an undercut shape toward the outer side in the radial direction is provided around the tip of the discharge cylinder portion 15, and the outer peripheral surface of the discharge cylinder portion 15 is formed in a concave cross-section, and convex ribs 15b that protrude toward the outer side in the radial direction are formed at a plurality of locations (four in this embodiment) in the circumferential direction at predetermined central angles (for example, 90 degrees).

[0017] As shown in FIGS. 2(a) and 2(b), an arc-shaped bottom wall portion 16 formed over a semi-circular portion is continuously provided on the inner side in the radial direction at the lower end of the inner cylinder portion 12. An inner wall 18 stands upright along the circumferential direction at a position on the inner edge of the bottom wall portion 16 and excluding the central portion in the circumferential direction, and a pair of connecting walls 19 that connect between the inner cylinder portion 12 and the inner wall 18 stand upright along the left-right direction at the end portions at both circumferential ends of the bottom wall portion 16. And the space surrounded by the inner cylinder portion 12, the bottom wall portion 16, the inner wall 18, and the connecting wall 19 is defined as a temporary storage chamber Q. In addition, at the central portion in the circumferential direction of the inner wall 18, a cap-side communication port 18A formed by radially notching the inner wall 18 is formed. The region inside the inner cylinder portion 12 penetrates vertically except for the region where the arcuate bottom wall portion 16 is formed. And, in Fig. 2(a), the small semi-circular region on the left side inside the inner wall 18 is the measuring region 17A, and the large region with a large height dimension consisting of the semi-circular shape on the right side other than that is the opening region 17B.

[0018] As shown in Fig. 3, the lid member 20 is formed having a disk-shaped top wall portion 21, a short cylindrical outer wall portion 22 hanging down from the outer peripheral end of the top wall portion 21, and an opening / closing lid 23 having a substantially arcuate shape in plan view.

[0019] At a position in front of the top wall portion 21, a top wall thin-walled portion 24A having a substantially arcuate shape is formed, and at a position in front of the outer wall portion 22, a side wall thin-walled portion 24B continuous with the outer wall portion 22 is formed. Discharge holes 25a are formed at a plurality of positions of the top wall thin-walled portion 24A, and the plurality of discharge holes 25a constitute a dispensing port 25. And, the opening / closing lid 23 and the top wall thin-walled portion 24A are connected so as to be openable and closable via a thin-walled hinge portion 21A provided at the boundary portion between the top wall portion 21 and the top wall thin-walled portion 24A. On the lower surface of the opening / closing lid 23, a plurality of plug portions 23a corresponding to the discharge holes 25a project respectively. When the opening / closing lid 23 covers the top wall thin-walled portion 24A and the side wall thin-walled portion 24B and is in the closed state (refer to the broken lines in Fig. 1(a) and Fig. 3(b)), the dispensing port 25 is closed by inserting each into the respective discharge holes 25a. In the closed state, the upper surface of the opening / closing lid 23 and the top wall portion 21 are set to be substantially on the same plane. Incidentally, at a position in front on the outer peripheral surface of the opening / closing lid 23 and on the side opposite to the hinge portion 21A, a knob piece 23b for opening and closing the opening / closing lid 23 projects.

[0020] As shown in FIG. 3(b), on the inner surface of the top wall portion 21, there are an inner rib 26 for sealing provided along the outer wall portion 22, a partition plate 27 hanging down at a position substantially directly below the hinge portion 21A, a short-side rib 28a extending rearward from this partition plate 27, and a long-side rib 28b extending in the left-right direction, projecting in an L-shaped configuration in plan view, and a pair of partition ribs 28 are formed with the short-side ribs 28a arranged at a predetermined interval in the radial direction.

[0021] Also, at the position of the lower end of the inner peripheral surface of the outer wall portion 22, it is formed in an undercut shape toward the radially inner side, engages with the engaged portion 15a formed on the outer peripheral surface of the discharge cylinder portion 15 on the cap body 10 side to attach the lid member 20 to the discharge cylinder portion 15, and a plurality of engaging portions 22a are provided so as to be able to contact the plurality of convex ribs 15b formed on the outer peripheral surface of the discharge cylinder portion 15 formed in a concave cross-sectional shape from the circumferential direction, projecting at a predetermined interval in the circumferential direction. Furthermore, at the position on the outer peripheral surface of the side wall thin-wall portion 24B that is the front front side, a locked projection 24a is projected to maintain the closed state of the opening / closing lid 23 by locking the inner surface on the front side of the opening / closing lid 23 facing this.

[0022] The metering member 30 is formed in a semi-circular shape in plan view as shown in FIG. 4(a), and has an inclined portion 31 formed by an inclined surface as shown in a longitudinal cross-section in FIG. 4(b), a partition plate 32 integrally hanging down vertically along the upper end of the inclined portion 31, and a pair of inclined side walls 33 formed in an arc shape in plan view along the side surface of the inclined portion 31. Also, a metering portion side communication port 34 that breaks through in the radial direction is formed to open at the front portion where the ends of the pair of inclined side walls 33 face each other in the circumferential direction. Furthermore, at the lower side position of the inclined portion 31, a pair of clamping walls 35 projecting parallel from one inclined side wall 33 toward the other inclined side wall 33 are respectively formed.

[0023] Next, the assembly of the dispensing cap having the above configuration will be described. FIG. 5 shows a state where the metering member is arranged on the cap body, (a) is a longitudinal cross-sectional view, and (b) is a plan view. First, as shown in FIG. 5, first place the measuring member 30 in the measuring region 17A of the cap body 10. That is, by installing the measuring member 30 having a semicircular shape in plan view inside the measuring region 17A having a semicircular shape in plan view, the measuring member 30 is arranged inside the cap body 10. In this state, the measuring member 30 is rotatable in the circumferential direction with respect to the cap body 10.

[0024] Also in this state, the partition plate 32 on the measuring member 30 side is arranged in a state of forming the same plane between a pair of connecting walls 19 of the cap body 10 located on both the left and right sides. And, the arc-shaped lower end 31A of the inclined portion 31 on the measuring member 30 side and the arc-shaped bottom wall portion 16 of the cap body 10 are connected at the same height position (see FIG. 5(a)). At the same time, the cap-side communication port 18A and the measuring-section-side communication port 34 are opposed and overlap in the radial direction, so that the space (communication space T described later) inside the measuring member 30 and the temporary storage chamber Q on the cap body 10 side are set to be connected.

[0025] Next, attach the lid member 20 onto the cap body 10 in which the measuring member 30 is arranged. That is, as shown in FIG. 1(a), insert the discharge cylinder portion 15 on the cap body 10 side between the outer wall portion 22 and the inner rib 26 on the lid member 20 side, and engage the engaging portion 22a on the lid member 20 side with the engaged portion 15a on the cap body 10 side. By assembling the lid member 20 to the cap body 10, the assembly of the dispensing cap 1 can be completed.

[0026] In a state where the lid member 20 is assembled to the discharge cylinder portion 15 on the cap body 10 side, the engaging portion 22a is circumferentially rotatable along the outer peripheral surface of the discharge cylinder portion 15 formed in a concave cross-section. The lid member 20 and the measuring member 30 are in a state of being integrally rotatable in the circumferential direction about the cap axis O with respect to the cap body 10.

[0027] Also, as shown in FIGS. 1(a) and 1(b), at the positions on both sides in the left - right direction, between a pair of clamping walls 35 provided on the metering member 30, a partition plate 27 that hangs down from the top wall portion 21 of the lid member 20 is clamped. A gap 27a is provided between the lower end of the partition plate 27 and the inner surface of the inclined portion 31, and the inside of the metering member 30 is partitioned into two front - rear spaces via the partition plate 27 and the gap 27a.

[0028] Furthermore, the upper end portion of the partition plate 32 of the metering member 30 and the inner surface of the top wall portion 21 of the lid member 20 are in contact with each other via a notch hole S formed in the partition plate 32, and the upper end portion of the partition plate 32 is in contact with each long - side rib 28b that constitutes a pair of left - right partition ribs 28 formed on the inner surface of the top wall portion 21 from the rear.

[0029] Among the two front - rear spaces, the rear space is partitioned into a substantially square shape in plan view by a partition plate 27 provided on all four sides to the front, a partition plate 32 provided at the rear, and a pair of short - side ribs 28a provided on the left and right, and is provided with a first metering chamber M1 provided upward. And a second metering chamber M2 which is composed of a slightly larger space partitioned by a partition plate 27 provided on all four sides to the front, a partition plate 32 provided at the rear, and a pair of inclined side walls 33 provided on the left and right at a position below the first metering chamber M1.

[0030] Also, the front space is provided between a partition plate 27 arranged between a pair of inclined side walls 33 provided on the left and right and a metering - part side communication port 34, and forms a communication space T that is connected to a temporary storage chamber Q on the cap - body 10 side via the above - mentioned cap - side communication port 18A and the metering - part side communication port 34.

[0031] Then, as shown in FIG. 1(a), the assembled dispensing cap 1 is attached and fixed to the upper part of the container body 50 in which the content P is stored by screwing the cap body 10 onto the mouth portion 51 of the container body 50. In the dispensing cap 1 of the present invention, the discharged content P is preferably in powder or granular form.

[0032] (Fixed - quantity dispensing state and dispensing operation) As shown in Fig. 1(a), the feature of the quantitative dispensing state is that a dispensing port 25 composed of a plurality of discharge holes 25a and an opening / closing lid 23 are arranged to face each other at a position directly above the temporary holding chamber Q.

[0033] Fig. 6 is a cross-sectional view showing the quantitative dispensing operation. Fig. 6(a) shows the weighing stage in an inverted state, Fig. 6(b) shows the temporary holding stage after returning to the upright state, and Fig. 6(c) shows the quantitative dispensing stage in an inverted posture again. To perform the quantitative dispensing operation, change from the upright state shown in Fig. 1(a) to the inverted state shown in Fig. 6(a). Then, the content P moves from the container body 50 onto the inner surface of the top wall portion 21 of the lid member 20 through the opening region 17B. At this time, a part of the content P can be moved into the first weighing chamber M1 through the notch hole S formed at the upper end portion of the partition plate 32.

[0034] By forming the first weighing chamber M1 with a predetermined size, the amount of movement of the content P is restricted so that a large amount of the content P does not enter the first weighing chamber M1 at once. The amount of the content P that can be moved into the first weighing chamber M1 at a time is set in advance according to the opposing interval of the pair of short side ribs 28a, the opposing interval between the partition plate 27 and the partition plate 32, and the height dimension of the notch hole S. That is, in the present invention, by setting these dimensions in advance, the content P moving from the notch hole S into the first weighing chamber M1 is always a constant amount, enabling the weighing of the content P using the first weighing chamber M1 (weighing stage).

[0035] Subsequently, as shown in Fig. 6(b), when the container body 50 is returned to the upright state, the content P falls from the first weighing chamber M1 to the second weighing chamber M2 below it, slides down the inclined portion 31, passes through the gap 27a and between the pair of clamping walls 35 on the left side and the pair of clamping walls 35 on the right side, and moves into the communication space T, and further passes between the cap-side communication port 18A and the weighing unit-side communication port 34 and moves into the temporary holding chamber Q (temporary holding stage). At the same time, the content P remaining on the top wall portion 21 can be returned into the container body 50 through the opening region 17B.

[0036] Finally, as shown in Fig. 6(c), when the opening / closing lid 23 is set to the open state and the container body 50 is set from the upright state to the inverted state again, the content P can be shaken out to the outside through a plurality of discharge holes 25a that constitute the discharge port 25 from the temporary storage chamber Q (quantitative shaking-out stage). Here, what is shaken out is a fixed amount of the content P that was measured in the previous weighing stage. Also, at this time, similar to the above weighing stage, the content P moves through the notch hole S to the first weighing chamber M1 and is weighed, and will be shaken out in the subsequent shaking-out stages.

[0037] (Optional shaking-out state) Fig. 7(a) is a longitudinal sectional view showing the shaking-out cap and the container set in the optional shaking-out state, and Fig. 7(b) is a bottom view of the shaking-out cap. The shaking-out cap 1 can be shifted to the optional shaking-out state shown in Fig. 7(a) by rotating the lid member 20 by half a turn (180 degrees) in the positive direction from the state shown in Fig. 1(a). That is, while referring to the alignment mark 11b formed on the cap body 10, the lid member 20 is rotated in the positive direction. At this time, the engaging portion 22a that moves in the positive direction along the outer peripheral surface of the discharge cylinder portion 15 rides over the convex rib 15b formed at a predetermined central angle each time. Therefore, since the operator can recognize that the rotation has been made by half a turn from the number of times the convex rib 15b has been ridden over, it is possible to surely shift the shaking-out cap 1 to the optional shaking-out state.

[0038] At this time, the metering member 30 assembled in an integrated state with the lid member 20 rotates together, but the cap body 10 remains in its position without rotating. For this reason, as shown in FIGS. 7(a) and 7(b), when the dispensing cap 1 is set to an arbitrary dispensing state, the metering member 30 moves from the metering region 17A into the opening region 17B, and the lower end 31A of the inclined portion 31 on the metering member 30 side and the inner cylinder portion 12 face each other in the radial direction within the rear opening region 17B, and an opening 36 having a semi-ring shape in plan view is formed at this facing portion. At the same time, the dispensing port 25 composed of a plurality of discharge holes 25a provided in the lid member 20 moves into the rear opening region 17B and is set to face the opening 36 in the vertical direction. Note that in the arbitrary dispensing state, it is possible to return to the original fixed-dose dispensing state by rotating the lid member 20 in the reverse direction by half a turn. (Arbitrary dispensing operation) In the arbitrary dispensing state, as shown in FIG. 8, by opening the opening / closing lid 23 and setting the dispensing port 25 to an inverted inclined state or an inverted state in which the dispensing port 25 faces downward, the content P in the container body 50 can be continuously discharged through the dispensing port 25 composed of the opening 36 and the plurality of discharge holes 25a.

[0039] As described above, in the present invention, by rotating the lid member 20 in the forward or reverse direction by half a turn with respect to the cap body 10, it is possible to freely switch between the fixed-dose dispensing state and the arbitrary dispensing state. Then, by performing the necessary operations in each state, it is possible to perform fixed-dose discharge of the content P from the dispensing port 25 composed of a plurality of discharge holes 25a or continuous arbitrary dispensing.

[0040] As described above, in the present invention, since the number of the dispensing port 25 and the opening / closing lid 23 on the lid member 20 can be minimized to one, the configuration of the dispensing cap 1 can be simplified as compared with the prior art.

[0041] As described above, the configuration and the operation and effect of the present invention have been described along with the embodiments. However, the embodiments of the present invention are not limited to the above embodiments. For example, in the above embodiment, the case where both sides of the partition plate 27 are sandwiched between a pair of sandwiching walls 35 arranged on both sides has been described. However, a configuration without providing the pair of sandwiching walls 35 may also be possible, or depending on the amount of movement of the content P moving on the inclined portion 31, a configuration without providing the partition plate 27 itself may also be adopted.

Industrial Applicability

[0042] The present invention can further expand the application development in the field of dispensing caps to a wider area.
