Description

[Technical Field]

[0001] The present invention relates to a dispensing cap. [Background technology]

[0002] Conventionally, there has been known a dispensing cap that includes a cap body that is attached to the mouth of a container body that contains a liquid content, and a dispensing plug that has a single dispensing hole for the liquid content, as shown in Patent Document 1. This type of dispensing cap is attached to the mouth of a container body that has a body that can be deformed by squeezing, and may be used to dispense the liquid content, such as mouthwash, into the oral cavity through the dispensing hole when the body is squeezed and deformed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-119452 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with this dispensing cap, when the contents are dispensed into the oral cavity through a single dispensing hole, there is a risk that the contents may reach the vicinity of the entrance to the throat, making it difficult to dispense the contents into an appropriate position in the oral cavity where they are likely to remain.

[0005] An object of the present invention is to provide a pouring cap that can pour the content liquid into an appropriate position in the oral cavity where it is likely to remain. [Means for solving the problem]

[0006] A dispensing cap according to one aspect of the present invention comprises a cap body that is attached to the mouth of a bottomed, cylindrical container body that contains a liquid content and has a squeezable body, and a dispensing tap that has a dispensing hole for the liquid content, wherein the cap body has a closing wall that closes the upper end opening of the mouth, and the closing wall has a communication hole that communicates with the inside of the container body and a connecting tube that surrounds the communication hole and extends upward, the dispensing tap is formed in a topped cylindrical shape that has a top wall and an attachment tube that is attached to the connecting tube, and a nozzle protrusion that protrudes obliquely upward is formed on the dispensing tap, and the The spout opening is located on the top surface of the nozzle protrusion facing diagonally upward, and a connecting path that connects the communication hole and the spout opening is provided between the blocking wall of the cap body and the top wall of the spout plug. When viewed from above on the top surface of the nozzle protrusion, the two spout openings are arranged side by side in a horizontal direction that intersects the vertical direction, and each extends diagonally upward from the connecting path. The two spout openings extend laterally away from each other as they extend diagonally upward from the connecting path, and the angle formed by the central axes of the two spout openings when viewed from the vertical direction is between 35° and 60°.

[0007] The two spouting holes, which are arranged side by side, extend diagonally upward from the connecting passage so that they move away from each other in the horizontal direction, and the angle formed by the central axes of the two spouting holes when viewed from above and below is between 35° and 60°. Therefore, the content liquid enters the oral cavity from the two spouting holes while being separated from each other by an appropriate distance in the horizontal direction, making it difficult for the content liquid to reach the area near the entrance of the throat, and the content liquid can be spouted to an appropriate position in the oral cavity where it is likely to remain. Since the two outlet holes are connected to a single connecting path provided between the blocking wall of the cap body and the top wall of the outlet plug, it is possible to prevent differences in the flow rates of the liquid contents being poured out from the two outlet holes when the body is squeezed and deformed, and to prevent the liquid contents being poured out from the outlet hole with such strong force that it is more likely to reach the entrance of the throat.

[0008] The mounting tube of the dispensing tap is fitted into the connecting tube so as to be able to move up and down, and the dispensing tap is provided on the cap body so as to be able to move up and down between a closed position in which communication between the communication hole and the dispensing hole through the connection path is blocked, and an open position which is located above the closed position and in which the communication hole and the dispensing hole communicate through the connection path, a lid body that opens and closes the dispensing hole is connected to the cap body via a hinge part, and a first engaging part and a second engaging part that are separately formed on the lid body and the dispensing tap and are able to detachably engage with each other, and when the lid body is rotated up and down around the hinge part, the first engaging part and the second engaging part engage with each other, and the dispensing tap moves up and down between the closed position and the open position.

[0009] When the lid body is rotated upward around the hinge portion to open the dispensing hole, the first engaging portion and the second engaging portion engage with each other, causing the dispensing tap to move from the closed position to the open position, the communication hole and the dispensing hole communicate through the connection path, and the contents become available for dispensing; when the lid body is rotated downward around the hinge portion to close the dispensing hole, the first engaging portion and the second engaging portion engage with each other, causing the dispensing tap to move from the open position to the closed position, blocking communication between the communication hole and the dispensing hole through the connection path. As a result, by rotating the lid body vertically around the hinge portion, the spout tap can be moved vertically between the closed position and the open position, providing excellent operability. Since the dispensing tap can be positioned in the closed position, the liquid contents can be prevented from leaking from the dispensing hole even if an unexpected external force is applied to the body during storage when the liquid contents are not being dispensed. [Effects of the Invention]

[0010] According to this invention, the liquid content can be poured out to an appropriate position in the oral cavity where it is likely to remain. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is a view showing the state in which the spout tap is in the open position in FIG. 1. [Figure 3] FIG. 2 is a view of FIG. 1 as seen from the front. [Figure 4] FIG. 2 is a top view of the spout tap of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, one embodiment of the dispensing cap will be described with reference to the drawings. As shown in Fig. 1, the dispensing cap 1 includes a cap body 11 and a dispensing tap 12. The cap body 11 and the dispensing tap 12 are formed in a cylindrical shape with a top, and are arranged coaxially with a common axis O1.

[0013] Hereinafter, the side of top wall 13 of spout 12 along common axis O1 will be referred to as the upper side, the side of the open end of peripheral wall 14 of cap body 11 along common axis O1 will be referred to as the lower side, and the direction along common axis O1 will be referred to as the up-down direction. When viewed from the up-down direction, the direction intersecting common axis O1 will be referred to as the radial direction, and the direction going around common axis O1 when viewed from the up-down direction will be referred to as the circumferential direction.

[0014] The cap body 11 is attached to the mouth W1 of a cylindrical container body W having a bottom. Here, a liquid content such as mouthwash is contained within the container body W. The body of the container body W is formed to be deformable by squeezing. A locking projection is formed on the outer peripheral surface of the mouth portion W1 of the container body W, projecting radially outward and extending continuously over the entire circumferential length.

[0015] The cap body 11 is formed in a cylindrical shape with a top, and includes a blocking wall 15 that blocks the upper end opening of the mouth portion W1, and a peripheral wall 14 that extends downward from the outer peripheral edge of the blocking wall 15 and is attached to the outer periphery of the mouth portion W1.

[0016] The inner peripheral surface of the peripheral wall 14 is formed with a locking projection that projects radially inward, extends continuously over the entire circumferential length, and engages with the locking projection of the opening portion W1 via an undercut. The closing wall 15 is formed with a communication hole 16 that communicates with the inside of the container body W, and a connecting tube 17 that surrounds the communication hole 16 and extends upward. The communication hole 16 and the connecting tube 17 are arranged coaxially on a common axis O1. The connecting tube 17 is provided on the upper surface of the closing wall 15 around the opening edge of the communication hole 16. The upper end of a supply tube 33 is fitted into the communication hole 16. The lower end of the supply tube 33 is located within the bottom of the container body W.

[0017] A plug 18 extending in the vertical direction is provided within the connecting tube 17 . The plug 18 is formed in the shape of a solid rod. The plug 18 is disposed coaxially with the common axis O1. A radial gap is provided between the outer peripheral surface of the plug 18 and the inner peripheral surface of the connecting tube 17. A guide protrusion 18b protruding upward is provided on the upper end surface of the plug 18. The guide protrusion 18b is configured such that a plate whose front and back surfaces face in one radial direction and a plate whose front and back surfaces face in another direction perpendicular to the one radial direction intersect on the common axis O1, and thus presents a cross shape when viewed from above.

[0018] An annular protrusion is formed on the inner peripheral surface of the connecting cylinder 17, protruding radially inward and extending continuously over the entire circumferential length. The protrusion is located above the upper surface of the blocking wall 15. The upper opening edge of the supply tube 33 abuts against the lower surface of the protrusion. The inner peripheral surface of the protrusion and the outer peripheral surface of the plug 18 are connected via a plurality of connecting pieces 18a spaced apart in the circumferential direction. The connecting pieces 18a are connected to the outer peripheral surface of the lower end of the plug 18. The protrusion may also be formed on the inner peripheral surface of the communicating hole 16.

[0019] A lid body 22 that opens and closes a pouring hole 21 formed in the pouring tap 12 is connected to the cap body 11 via a hinge portion 23 .

[0020] The cover 22 is formed in a cylindrical shape with a top. A protrusion 24 that protrudes downward and an engagement cylinder 25 that protrudes downward are formed on the top wall of the cover 22. The protrusion 24 and the engagement cylinder 25 are arranged coaxially with a common axis O1. The engagement cylinder 25 surrounds the protrusion 24 from the outside in the radial direction. The lower end of the engagement cylinder 25 is located below the lower end of the protrusion 24. A first engagement portion 25a that protrudes radially inward is formed on the inner circumferential surface of the lower end of the engagement cylinder 25. The hinge portion 23 connects the lower end of the peripheral wall of the lid body 22 and the upper end of the peripheral wall 14 of the cap body 11 .

[0021] Hereinafter, the radial side where the hinge portion 23 is provided relative to the common axis O1 will be referred to as the rear side, and the radial side opposite the side where the hinge portion 23 is provided relative to the common axis O1 will be referred to as the front side.

[0022] An operation piece 22a protruding forward is formed on the outer peripheral surface of the front end of the peripheral wall of the cover body 22. As shown in Fig. 3, the operation piece 22a is formed as a protrusion extending in the circumferential direction. The operation piece 22a is formed on the lower end of the peripheral wall of the cover body 22.

[0023] A guide plate 26 that protrudes downward is provided on the outer peripheral surface of the front end of the peripheral wall of the cover body 22. The guide plate 26 protrudes downward from the underside of the operating piece 22a. The lower end of the guide plate 26 is located below the edge of the lower opening of the peripheral wall of the cover body 22. The guide plate 26 is formed in a plate shape with its front and back surfaces facing the front-to-rear direction. An opening 26a that runs through the guide plate 26 in the front-to-rear direction and opens downward is formed in the guide plate 26. The opening 26a has a rectangular shape when viewed from the front-to-rear direction, with two of its four sides extending in the up-down direction and the remaining two sides extending in the circumferential direction. The two upper corners of the opening 26a are formed in an R-shape. Here, a recess 14a is formed on the outer peripheral surface of the front end of the peripheral wall 14 of the cap body 11, which is recessed radially inward and opens upward, and a guide plate 26 is inserted into the recess 14a.

[0024] The dispensing tap 12 is formed in the shape of a cylinder with a top, and includes a top wall 13 and an attachment tube 27 attached to the connecting tube 17 of the cap body 11 .

[0025] The mounting tube 27 is fitted to the connecting tube 17 of the cap body 11 so as to be movable up and down. The mounting tube 27 is formed in a double-cylinder shape having an outer tube 27a and an inner tube 27b, and the connecting tube 17 is tightly inserted between the inner peripheral surface of the outer tube 27a and the outer peripheral surface of the inner tube 27b so as to be slidable up and down. The spout 12 is formed with a communication tube 28 that protrudes downward from the top wall 13 and is fitted to the stopper body 18 and the guide protrusion 18b so as to be able to slide up and down. The communication tube 28 is disposed coaxially with the common axis O1. The spout hole 21 opens on the inner peripheral surface of the communication tube 28.

[0026] A spout hole 21 is formed in the top wall 13 of the spout tap 12. The top wall 13 of the spout tap 12 is formed in a conical shape that extends upward as it moves radially inward. A nozzle protrusion 31 that protrudes diagonally upward is formed on the top wall 13.

[0027] A recessed portion 31b is formed in a portion of the nozzle protrusion 31 that faces upward and is located on the common axis O1. The protrusion 24 of the lid body 22 is inserted into the recessed portion 31b, and the lower end surface of the protrusion 24 abuts against the bottom surface of the recessed portion 31b. The lower end face of protrusion 24 abuts against the upper end face of guide protrusion 18b in the vertical direction via top wall 13 of dispensing tap 12. This restricts unintended upward movement of dispensing tap 12 relative to cap body 11, and prevents the content liquid in container body W from leaking from dispensing hole 21 and accumulating between cap body 11 and lid body 22.

[0028] Nozzle projection 31 projects obliquely upward and facing forward from top wall 13. Spout hole 21 opens in top surface 31a of nozzle projection 31 facing obliquely upward. 4, the two spouting holes 21 are arranged side by side in a horizontal direction intersecting the vertical direction in a plan view of the top surface 31a of the nozzle protrusion 31. In the illustrated example, the horizontal direction is the left-right direction, which is a radial direction perpendicular to the front-rear direction.

[0029] Here, a connection passage 32 that connects the pouring hole 21 and the communication hole 16 is provided between the top wall 13 and the closing wall 15 of the cap body 11. The connection passage 32 extends in the vertical direction. The connection passage 32 is formed by the insides of the communication tube 28, the inner tube 27b, and the connecting tube 17.

[0030] The two pouring holes 21 each extend obliquely upward and facing forward from the connecting passage 32. In a vertical cross-sectional view along the up-down direction, the direction in which the two pouring holes 21 extend from the connecting passage 32 coincides with the direction in which the nozzle protrusion 31 protrudes from the top wall 13. 4, the two pouring holes 21 extend diagonally upward from the connecting passage 32, moving away from each other in the left-right direction. When viewed from the top-bottom direction, the angle θ formed by the central axes O2 of the two pouring holes 21 is 35° or more and 60° or less, and preferably 40° or more and 55° or less. When viewed from the top-bottom direction, the intersection of the central axes O2 of the two pouring holes 21 is located on a common axis O1.

[0031] The dispensing tap 12 is provided on the cap body 11 so as to be movable up and down between a closed position in which communication between the communication hole 16 and the dispensing hole 21 through the connection path 32 is blocked, and an open position in which the communication hole 16 and the dispensing hole 21 are connected through the connection path 32. In the closed position, as shown in Figure 1, the communication tube 28 of the spout tap 12 is tightly fitted into the stopper body 18. In the open position, as shown in Figure 2, the spout tap 12 is positioned higher than in the closed position, and the communication tube 28 of the spout tap 12 moves upward away from the stopper body 18 while remaining fitted into the guide protrusion 18b.

[0032] The lid body 22 and the dispensing tap 12 are respectively formed with a first engaging portion 25a and a second engaging portion 12a that are detachably engaged with each other. As described above, the first engagement portion 25a is formed on the inner circumferential surface of the lower end of the engagement tube 25 of the lid body 22. The second engagement portion 12a protrudes radially outward from the outer circumferential edge of the top wall 13 of the spout faucet 12. The first engagement portion 25a and the second engagement portion 12a extend continuously over the entire circumferential length. The first engagement portion 25a and the second engagement portion 12a are formed with a curved surface that protrudes radially. In the closed position, the first engagement portion 25a is undercut-fitted into the second engagement portion 12a so as to be able to disengage upward.

[0033] When the lid body 22 is rotated up and down around the hinge portion 23, the first engagement portion 25a and the second engagement portion 12a engage with each other, and the spout 12 moves up and down between the closed position and the open position.

[0034] In the illustrated example, when operating piece 22a of lid body 22 is pulled up from the storage state shown in Fig. 1 and lid body 22 is rotated upward around hinge portion 23, first engagement portion 25a and second engagement portion 12a engage with each other, and spout tap 12, which is in the closed position, is pulled up by lid body 22 and moves toward the open position. As a result, as shown in Fig. 2, communication tube 28 of spout tap 12 moves upward away from stopper body 18, and spout hole 21 and the inside of supply tube 33 (communication hole 16) communicate with each other through connection path 32.

[0035] Then, by inserting the nose into the opening 26a of the guide plate 26 and with the outlet hole 21 facing the oral cavity, the body of the container body W is squeezed and deformed, so that the liquid contents are poured from the outlet hole 21 into the oral cavity through the supply tube 33 and the connecting path 32.

[0036] Thereafter, when the lid body 22 is rotated downward around the hinge portion 23, the first engaging portion 25a and the second engaging portion 12a engage with each other, and the dispensing tap 12, which is in the open position, is pushed down by the lid body 22 and moves toward the closed position. As a result, as shown in Figure 1, the stopper body 18 is tightly fitted into the communication tube 28 of the dispensing tap 12, and communication between the dispensing hole 21 and the inside of the supply tube 33 (communication hole 16) through the connection path 32 is blocked.

[0037] As described above, according to the dispensing cap 1 of this embodiment, the two dispensing holes 21 arranged side by side in the left-right direction (horizontal direction) extend in a direction that moves away from each other horizontally as they extend diagonally upward from the connecting passage 32, and when viewed from the top-bottom direction, the angle θ formed by the central axes O2 of the two dispensing holes 21 is greater than or equal to 35° and less than or equal to 60°. Therefore, the liquid contents enter the oral cavity from the two outlet holes 21 at an appropriate distance from each other in the left and right directions, making it difficult for the liquid contents to reach the vicinity of the entrance of the throat, and the liquid contents can be poured out at an appropriate position in the oral cavity where they are likely to remain.

[0038] Since the two dispensing holes 21 are connected to one connecting passage 32 provided between the blocking wall 15 of the cap body 11 and the top wall 13 of the dispensing tap 12, it is possible to prevent differences in the flow rates of the content liquid dispensed from the two dispensing holes 21 when the body is squeezed and deformed, and to prevent the content liquid from being dispensed from the dispensing hole 21 with such strong force that it easily reaches the vicinity of the entrance of the throat.

[0039] When the lid body 22 is rotated upward around the hinge portion 23 to open the dispensing hole 21, the first engagement portion 25a and the second engagement portion 12a engage with each other, causing the dispensing tap 12 to move from the closed position to the open position, connecting the inside of the supply tube 33 (communication hole 16) to the dispensing hole 21 through the connecting path 32 and enabling the contents to be dispensed, and when the lid body 22 is rotated downward around the hinge portion 23 to close the dispensing hole 21, the first engagement portion 25a and the second engagement portion 12a engage with each other, causing the dispensing tap 12 to move from the open position to the closed position, blocking communication between the inside of the supply tube 33 and the dispensing hole 21 through the connecting path 32. As a result, by rotating the lid body 22 vertically around the hinge portion 23, the spout tap 12 can be moved vertically between the closed position and the open position, providing excellent operability.

[0040] Since the dispensing plug 12 can be positioned at the closed position, even if an unexpected external force is applied to the body of the container body W during storage without dispensing the content liquid, the content liquid can be prevented from leaking from the dispensing hole 21.

[0041] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0042] For example, the lid body 22 does not need to be provided with the engaging cylinder 25 and the guide plate 26 . The dispensing tap 12 may be provided on the cap body 11 in a state where it is fixed in the open position. The dispensing hole 21 and the nozzle projection 31 may be formed on the mounting cylinder 27 of the dispensing tap 12 .

[0043] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate.
