Description

[Technical Field]

[0001] The present invention relates to a discharge cap for discharging, for example, a highly viscous paste-like content. [Background technology]

[0002] Conventionally, a container has been proposed that includes a container body that contains a highly viscous paste and a cap that is removably attached to the mouth of the container body to close the mouth of the container body (see, for example, Patent Document 1). In such containers, the container body is a compressible tube container or squeeze container, and the contents are discharged from the discharge hole of the container body by squeezing the container body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-081053 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional discharge caps, even when the container body is released from compression to dispense the desired amount of contents, the contents being dispensed in a rod-like form from the flow hole remain connected to the contents inside the container body, making it difficult to cut the contents at the desired location. Therefore, it may be difficult to easily dispense the desired amount of contents. Furthermore, if an attempt is made to cut the connected contents by rubbing the opening of the container body against another container, such as a plate, while the contents are being dispensed from the discharge hole, substances other than the contents may unintentionally adhere to the opening of the container body.

[0005] The present invention has been made in view of the above-mentioned problems, and has an object to provide a discharge cap that makes it easy to dispense a desired amount of content. [Means for solving the problem]

[0006] The present invention employs the following means to solve the above-mentioned problems. That is, the present invention provides a topped, cylindrical discharge cap that is attached to the mouth of a container body that contains contents, comprising: a cylindrical attachment body that is attached to the mouth and has a top wall portion formed with a discharge hole through which the contents in the container body are discharged; and a movable body that is disposed inside the cylindrical attachment body and has a circulation hole formed therein that allows the contents in the container body to flow toward the discharge hole, wherein the cylindrical attachment body is provided with an operating part that moves the movable body between a close position where an opening edge of the circulation hole in the movable body is located close to the opening edge of the discharge hole in the cylindrical attachment body, and a far position where the opening edge of the circulation hole is located farther away from the opening edge of the discharge hole than the close position.

[0007] In this invention, when a predetermined amount of contents is being discharged from the discharge hole, the operating unit is operated to move the movable body from the close position to the separated position. As the movable body moves, the portions of the contents located at the discharge hole and the flow hole are stretched, and the stretched portions become thinner. This narrowed portion then serves as the starting point for shearing the contents. Even if the stretched portion does not tear, the contents can be easily sheared from the narrowed portion. This makes it possible to remove the desired amount of contents from the container body. After the predetermined amount of contents has been discharged, the movable body can return from the separated position to the close position due to the restoring deformation of the operating unit or due to the pressure of the contents moving toward the discharge hole through the flow hole during the next discharge.

[0008] Furthermore, in the present invention, the top wall portion of the mounting cylinder may be provided with a discharge cylinder portion having the discharge hole formed at its tip, and the movable body may have a movable cylinder portion arranged inside the discharge cylinder portion so as to be movable between the close position and the separated position relative to the discharge cylinder portion, and having the flow hole formed at its tip. In this invention, when the container body is squeezed, the contents are guided into the movable cylindrical portion and discharged through the flow hole of the movable cylindrical portion and the discharge hole of the discharge cylindrical portion, thereby enabling stable discharge of the contents through the flow hole and the discharge hole. Furthermore, since the contact area of ​​the contents with the movable body increases as the contents pass through the movable cylindrical portion, when the movable body is moved from the close position to the separated position, the contents inside the movable cylindrical portion move together with the movable cylindrical portion, and the portion of the contents located at the discharge hole and the flow hole can be stretched more effectively.

[0009] In the present invention, an annular flange portion that protrudes inward and defines the flow hole may be formed at the tip of the movable cylindrical portion. In this invention, when the movable body, and therefore the movable cylindrical portion, moves to the separated position, the contents inside the movable cylindrical portion are caught on the flange portion and pulled, making it easier to stretch the contents located in the discharge hole and the flow hole.

[0010] In addition, in the present invention, the top wall portion of the mounting cylinder is provided with an elastic operating portion to which the movable body is fixed and which moves the movable body between the close position and the separated position, and the movable body may have a fixing portion fixed to the elastic operating portion of the mounting cylinder. In this invention, the movable body can be moved from the close position to the separated position by pressing the elastic operating part. Also, when the pressing of the elastic operating part is released, the movable body can be returned from the separated position to the close position by the restoring deformation. Therefore, the operability of the discharge cap is improved.

[0011] In the present invention, the elastic operating portion may be formed on the top wall portion and bulge out in a dome shape. In this invention, since the elastic operating portion is dome-shaped, the elastic operating portion can be stably restored to its original shape after the pressing force is released.

[0012] In the present invention, a protrusion that protrudes inward may be formed on at least one of the inner circumferential surface of the discharge hole and the inner circumferential surface of the flow hole. In this invention, the protrusion makes it easier to cut the contents starting from the protrusion, improving the operability of the discharge cap. In particular, if the movable body has a protrusion formed on the opening edge of the flow hole, this protrusion can catch on the contents located in the flow hole, and when the movable body is moved to the separated position, the contents can be pulled together with the movable body, making it easier to stretch the contents located at the discharge hole and the flow hole. [Effects of the Invention]

[0013] With the discharge cap according to the present invention, when the contents are discharged from the discharge hole, the operating part is operated to move the movable body to the separated position, and the portion of the contents located at the discharge hole and the flow hole is stretched by the movable body, making it easier to cut the contents from this stretched portion, thereby making it easy to take out a predetermined amount of contents.

[Figure 4] FIG. 2 is an axial cross-sectional view illustrating how to use the discharge cap of FIG. 1, illustrating how the discharged contents are cut off. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of a discharge cap according to the present invention will be described with reference to the drawings. As shown in Fig. 1, the discharge cap 1 according to this embodiment is attached to a cylindrical opening 3 of a compressible elastic container body 2. The discharge cap 1 is screwed onto the cylindrical opening 3 of the container body 2 and includes a topped cylindrical mounting cylinder 11 having a discharge hole 11A for discharging the contents, a topped cylindrical lid body 12 connected to the mounting cylinder 11 via a hinge (not shown), and a movable body 13. 1, the central axis of the discharge cap 1 will be referred to as the cap axis O, and the direction from the mounting cylinder 11 toward the lid 12 along this cap axis O will be referred to as the upward direction, and the opposite direction will be referred to as the downward direction. Furthermore, the direction intersecting the cap axis O in a plan view seen from the cap axis O will be referred to as the radial direction, and the direction going around the cap axis O will be referred to as the circumferential direction. Furthermore, in the radial direction, the position of the discharge hole 11A relative to the cap axis O in the mounting cylinder 11, which is circular in a plan view seen from the cap axis O, will be referred to as the front, and the opposite direction will be referred to as the rear, and the direction perpendicular to the front-rear direction and the cap axis O will be referred to as the left-right direction.

[0016] The mounting cylinder 11 has a cylindrical mounting cylinder portion 21 and a disk-shaped top wall portion 22 connected to the upper edge of the mounting cylinder portion 21. A female screw portion 21A is formed on the inner peripheral surface of the mounting cylinder portion 21 to screw into a male screw portion 3A formed on the outer peripheral surface of the mouth portion 3 of the container body 2. A discharge hole 11A that is circular in plan view is formed in the top wall portion 22, and a cylindrical discharge tube portion 23 that protrudes upward extends from the opening edge of the discharge hole 11A in the top wall portion 22. The center of the discharge hole 11A, i.e., the central axis O1 of the discharge tube portion 23, is located forward of the cap axis O. The inner and outer diameters of the upper end of the discharge tube portion 23 are inclined so as to gradually decrease upward, and a ring-shaped first flange portion 23A that protrudes toward the central axis of the discharge tube portion 23 is formed on the opening edge of the upper end of the discharge tube portion 23. The discharge hole 11A is defined by the opening edge of this first flange portion 23A.

[0017] The top wall 22 is also formed with a bulging portion (operating portion, elastic operating portion) 24 that bulges upward and has a circular shape in a plan view. The bulging portion 24 is dome-shaped, and the central axis of the bulging portion 24 is located rearward of the cap axis O. The central axis O2 of the bulging portion 24, the cap axis O, and the central axis O1 of the discharge tube portion 23 are arranged in this order in the front-to-rear direction in a plan view. The bulging portion 24 is thinner than the portions of the top wall 22 other than the bulging portion 24, which makes it more susceptible to elastic deformation. A cylindrical fixed tube portion 25, to which the movable body 13 is fixed, protrudes downward from the underside of the central portion of the bulging portion 24. The central axis of the fixed tube portion 25 is coaxial with the central axis O2 of the bulging portion 24. Furthermore, the outer peripheral edge of the top wall portion 22 is located radially inward from the outer peripheral surface of the mounting tube portion 21, and a first locking protrusion 22A is formed around the entire outer peripheral edge of the top wall portion 22, protruding radially outward and with which the lid body 12 snaps into engagement.

[0018] The lid body 12 has a cylindrical peripheral portion 31 and a disk-shaped top plate portion 32 connected to the upper edge of the peripheral portion 31. The outer diameter of the circumferential cylinder portion 31 is equal to the outer diameter of the mounting cylinder portion 21. The inner circumferential surface of the lower end of the circumferential cylinder portion 31 is recessed radially outward along the entire circumference, and a second locking projection 31A is formed around the entire circumference in this recessed portion of the inner circumferential surface of the circumferential cylinder portion 31, protruding radially inward and locking from below with the first locking projection 22A of the top wall portion 22. The lower end surface of the circumferential cylinder portion 31 abuts or is close to the upper end surface of the mounting cylinder portion 21 that is exposed from the top wall portion 22, and the upper end surface of the circumferential cylinder portion 31 that defines the recessed portion abuts or is close to the upper surface of the top wall portion 22.

[0019] The right end of the lower end of the circumferential cylinder portion 31 is connected by the hinge to the right end of the upper end of the mounting cylinder portion 21. Furthermore, a knob portion (not shown) protrudes radially outward from the left end of the lower end of the circumferential cylinder portion 31 and is used when rotating the lid body 12 around the hinge relative to the mounting cylinder 11. In this way, the front-to-rear direction, which is the arrangement direction of the discharge cylinder portion 23, the cap shaft O, and the bulge portion 24, and the left-to-right direction, which is the arrangement direction of the hinge, the cap shaft O, and the knob portion, are perpendicular in plan view.

[0020] A cylindrical first seal tube 32A and a cylindrical second seal tube 32B extend downward from the underside of the top plate 32. The central axes of the first seal tube 32A and the second seal tube 32B are coaxial with the central axis O1 of the discharge tube 23. The first seal tube 32A is arranged to surround the discharge tube 23 in a plan view, and the inner circumferential surface of the lower end of the first seal tube 32A abuts or is close to the outer circumferential surface of the discharge tube 23. The second seal tube 32B is arranged inside the first seal tube 32A and the discharge tube 23 in a plan view, and the lower end of the second seal tube 32B abuts or is close to the opening edge of the first flange 23A of the discharge tube 23. This more reliably prevents the contents from leaking through the discharge hole 11A of the discharge tube 23 when the lid 12 is closed.

[0021] As shown in Figures 1, 2(a) and 2(b), the movable body 13 has a plate-shaped fixed portion 41 and a cylindrical tubular portion (movable tubular portion) 42 connected to the front end edge of the fixed portion 41. The fixed portion 41 extends in the front-rear direction, and a cylindrical fixed pillar portion 43 protrudes upward from the upper surface of the rear end portion of the fixed portion 41. The central axis of the fixed pillar portion 43 is coaxial with the central axis O2 of the bulging portion 24, and the fixed pillar portion 43 is inserted into the fixed cylinder portion 25 formed in the bulging portion 24 and fitted into the fixed cylinder portion 25.

[0022] The lower edge of the rear end of the cylindrical portion 42 is connected to the front edge of the fixed portion 41. The central axis of the cylindrical portion 42 is coaxial with the central axis O1 of the discharge cylindrical portion 23, and the outer diameter of the cylindrical portion 42 is equal to the inner diameter of the discharge cylindrical portion 23. This allows the cylindrical portion 42 to move up and down inside the discharge cylindrical portion 23. The lower edge of the cylindrical portion 42 is inclined upward from the rear to the front, and the inner and outer diameters of the upper end of the cylindrical portion 42 are inclined so as to gradually decrease upward. In addition, an annular second flange portion (flange portion) 42A is formed on the upper edge of the cylindrical portion 42 and protrudes toward the central axis of the cylindrical portion 42. A flow hole 42B is defined by the opening edge of this second flange portion 42A. The opening diameter of the flow holes 42B defined by the second flange portion 42A is slightly larger than the opening diameter of the discharge hole 11A defined by the first flange portion 23A. This allows the first flange portion 23A to provide higher resistance to the contents passing through the discharge hole 11A. The opening diameter of the flow holes 42B defined by the second flange portion 42A may be equal to the opening diameter of the discharge hole 11A defined by the first flange portion 23A. The upper surface of the second flange portion 42A abuts or is close to the lower surface of the first flange portion 23A. Furthermore, the inner peripheral edge of the second flange portion 42A is wavy in a direction circumferentially around the central axis of the tubular portion 42. This forms a protrusion 42C on the flange portion 42A.

[0023] The container body 2 is a squeezable container such as a tube container or a squeeze container. The contents contained in the container body 2 are paste-like contents with a relatively high viscosity, such as wasabi paste, seasoning paste, facial cleanser, or cosmetics.

[0024] Next, we will explain how to use the discharge cap 1 configured as described above. First, the knob is operated to rotate the lid body 12 around the hinge relative to the mounting tube 11, exposing the discharge hole 11A. Then, the container body 2 is squeezed, and the contents within the container body 2 are moved toward the discharge hole 11A along arrow A1, as shown in FIG. 3. At this time, the movable body 13 is in a proximity position where the upper surface of the second flange portion 42A abuts or is close to the lower surface of the first flange portion 23A, and the contents P within the container body 2 are discharged to the outside through the flow hole 42B of the movable body 13 and the discharge hole 11A of the discharge tube portion 23, as shown by arrow A2. Note that the contents are discharged in a soft, rod-like shape due to their viscosity.

[0025] After a desired amount of contents P is discharged from the discharge hole 11A, the bulging portion 24 is pushed downward in the direction of arrow A3, as shown in FIG. 4, causing elastic deformation. As the bulging portion 24 is pushed downward, the movable body 13 also moves downward, as shown in FIG. 4. As the tubular portion 42 moves downward relative to the discharge tube portion 23, the second flange portion 42A of the movable body 13 moves downward away from the first flange portion 23A of the discharge tube portion 23, and the movable body 13 reaches the separated position. This widens the gap between the discharge hole 11A and the flow hole 42B, and the contents P located at the discharge hole 11A and the flow hole 42B are pulled in the vertical direction. The stretched portion of the contents is stretched thinly due to its viscosity, and this thinned portion of the contents is more likely to tear or will tear than other portions of the contents. As a result, the contents are cut at the thinned portion, allowing the desired amount of contents to be taken out (see contents P indicated by the two-dot chain line in FIG. 4).

[0026] Here, the inner diameter of the upper end of the tubular portion 42 tapers upward, and the second flange portion 42A is formed on the upper edge of the tubular portion 42. Therefore, when the movable body 13, i.e., the tubular portion 42, moves downward relative to the discharge tubular portion 23, the contents filling the inside of the upper end of the tubular portion 42 are easily pulled downward by the tapered inner circumferential surface at the upper end of the tubular portion 42 and the lower surface of the second flange portion 42A. This makes it easy to thin the pulled portion of the contents. Furthermore, because the inner circumferential edge of the second flange portion 42A is corrugated in a direction circumferentially around the central axis of the tubular portion 42, the thinned contents can be easily cut using the protruding portions 42C that form the convex portions of the corrugation as starting points. Furthermore, the front-to-back direction, which is the arrangement direction of the discharge tube portion 23, cap axis O, and bulge portion 24, and the left-to-right direction, which is the arrangement direction of the hinge, cap axis O, and knob portion, are perpendicular in a plan view, so when the lid body 12 is rotated around the hinge relative to the mounting tube body 11 and the bulge portion 24 is pushed in, the lid body 12 in the open state is unlikely to hinder the pushing action of the bulge portion 24.

[0027] After the desired amount of contents has been discharged, the pushing of the bulging portion 24 is released. The bulging portion 24 undergoes restoration deformation when the pushing is released, and the movable body 13 returns from the separated position to the approaching position. Note that even if the bulging portion 24 does not restore its original deformation when the pushing of the bulging portion 24 is released, the next time the container body 2 is compressed to discharge the contents, the contents of the container body 2 will flow toward the flow hole 42B and the discharge hole 11A, causing the bulging portion 24 to restore its original displacement and the movable body 13 to return from the separated position to the approaching position. Thereafter, the lid 12 is rotated around the hinge to close the discharge hole 11A. In this manner, the discharge cap 1 is used.

[0028] As described above, with the discharge cap 1 according to this embodiment, when the contents are discharged from the discharge hole 11A, the bulging portion 24 is pressed to move the movable body 13 to the separated position, and the portion of the contents located at the discharge hole 11A and the flow hole 42B is stretched, making it easier to cut the contents from this stretched portion, thereby making it easier to take out the desired amount of contents.

[0029] Here, when the contents are discharged, they are guided into the tubular portion 42 and discharged through the flow hole 42B of the tubular portion 42 and the discharge hole 11A of the discharge tubular portion 23, resulting in a stable discharge of the contents. Furthermore, by increasing the contact area between the contents and the tubular portion 42 when the contents are discharged, the movable body 13 is moved from the close position to the separated position, and together with the tubular portion 42, the contents inside the tubular portion 42 are pulled toward the separated position, thereby more effectively stretching the portions of the contents located at the discharge hole 11A and the flow hole 42B. Furthermore, by providing the tubular portion 42 with a second flange portion 42A, the second flange portion 42A can pull the contents inside the tubular portion 42 downward when the movable body 13 is moved toward the separated position, thereby more effectively stretching the portions of the contents located at the discharge hole 11A and the flow hole 42B.

[0030] By pressing the elastic bulging portion 24, the cylindrical portion 42 can be moved from the close position to the separate position. Furthermore, when the pressing of the bulging portion 24 is released, the movable body 13 can be returned from the separate position to the close position by the restoration of its original shape. This improves the operability of the discharge cap 1. In particular, because the bulging portion 24 is dome-shaped, the restoration of the bulging portion 24 after the pressing is released is stable.

[0031] Furthermore, the opening edge of the second flange portion 42A of the movable body 13 has a wavy shape, and the contents can be easily cut starting from the protrusion 42C, further improving the operability of the discharge cap 1. Furthermore, when the movable body 13 moves to the separated position, the wavy protrusion 42C catches on the contents located in the circulation hole 42B, and the contents can be pulled downward together with the tubular portion 42, making it easier to stretch the contents located in the discharge hole 11A and the circulation hole 42B.

[0032] 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. For example, the mounting cylinder and the lid are connected via a hinge to form an integrated member, but as long as the lid can be attached to the mounting cylinder in a detachable manner, the mounting cylinder and the lid do not have to be formed as an integrated unit, and the attachment of the lid to the mounting cylinder is not limited to snap engagement but may be other attachment methods such as screwing. Also, the discharge cap does not necessarily have to include a lid. The discharge hole is formed forward of the cap shaft, but may be formed so that its central axis is coaxial with the cap shaft. Although the discharge tube is provided on the top wall of the mounting tube and the movable tube is provided on the movable body, the movable body does not need to have a movable tube as long as it is movable within the discharge tube and has a portion where a flow hole is formed. Even in this case, the contents are guided to the discharge hole by the discharge tube, so that stable discharge of the contents is possible. Also, the discharge tube does not need to be provided on the top wall of the mounting tube. For example, the top wall of the mounting tube may be tapered, sloping upward from the outer periphery toward the center, so that the contents are guided to the discharge hole defined in the center. The operating unit is configured as a dome-shaped bulge formed on the top wall, but may have any other shape or configuration as long as it can move the movable body between the close position and the separated position. Although the opening edge portion of the second flange portion that defines the flow hole is corrugated, the opening edge portion of the first flange portion that defines the discharge hole may also be corrugated, and is not limited to a corrugated shape as long as a protrusion is formed. Furthermore, in addition to corrugating the opening edge portion of at least one of the first and second flange portions, both may have a non-corrugated shape. Furthermore, the protrusion may be formed in a shape other than a corrugated shape. The second flange portion does not necessarily have to be provided on the cylindrical portion of the movable body. The container body is a squeezable container such as a tube container or a squeeze container, but may be other containers. The discharge cap is screwed onto the opening of the container body, but may be attached to the opening of the container body in other ways, such as by fitting. Here, the discharge cap may be permanently attached to the opening of the container body.
