Description

The present invention relates to a hinge cap in which an upper lid is provided on the main body via a hinge.

As a cap attached to the container, a hinge cap including a main body attached to the mouth of the container and an upper lid provided on the main body via a hinge is widely known. Further, a dispensing cylinder for guiding the contents when the contents in the container is dispensed is formed in the main body so as to extend upward in a tubular shape, and a partition wall having a planned opening portion is formed inside the dispensing cylinder. It is also widely known that the container is opened by breaking the planned opening portion and opening the container. The upper lid is formed with a seal portion such as an inner ring that is in close contact with the pouring cylinder of the main body.

As an example of the conventionally known configuration of the hinge cap injection cylinder, as shown in FIGS. 13 and 14, the hinge cap 60 (also referred to as the hinge cap 60 of the first conventional example) injection cylinder 64 However, it is formed at the same height in the circumferential direction so as to stand relatively large (high) above the partition wall 66 that closes the inside of the container. Such a hinge cap 60 of the first conventional example is disclosed in, for example, FIG. 3 of Patent Document 1. In the plan view shown in FIG. 14, hatching is provided so that the range in which the dispensing cylinder 64 (the tip end portion of the dispensing cylinder 64) is provided can be easily understood.

Further, as another example of the conventionally known hinge cap injection cylinder, as shown in FIGS. 15 and 16, the hinge cap 80 (also referred to as the hinge cap 80 of the second conventional example) is dispensed. In the cylinder 84, the portion 84b on the side away from the hinge 83 is formed so as to stand larger (higher) above the portion 84c on the side closer to the hinge 83. In the plan view shown in FIG. 16, hatching is provided so that the range in which the high portion 84b of the dispensing cylinder 84 (the tip of the dispensing cylinder 84) is provided is shown. There is. Such a hinge cap 80 of the second conventional example is disclosed in FIG. 11 of Patent Document 2, for example.

In the hinge cap 60 of the first conventional example shown in FIGS. 13 and 14, and the hinge cap 80 of the second conventional example shown in FIGS. 15 and 16, 61 and 81 are the main bodies, and 62 and 82 are The upper lids 63 and 83 are hinges, 65 and 85 are thin walls for breaking the planned opening, and 66 and 86 are partition walls. In these conventional hinge caps 60 and 80, in general, the vertical positions of the opening and closing portions of the upper lids 62 and 82 and the main bodies 61 and 81 are set to be substantially the same height in the circumferential direction, and the hinges 63 and 83 are provided. The height is the same for both the hinges 63 and 83.

In the hinge cap 60 of the first conventional example as shown in FIGS. 13 and 14, as shown in FIG. 17, the inner ring 68 and the outer portion 69 have relatively small dimensions from the lid plate 67 of the upper lid 62. It is formed to hang down (short). When the upper lid 62 is closed, the inner ring 68 of the upper lid 62 is in contact with the tip 64a of the pouring cylinder 64 in a point-like manner from the inside in the vertical direction (in a linear contact in the circumferential direction) to seal. To do. When the upper lid 62 is closed, the outer portion 69 of the upper lid 62 is in contact with the tip portion 64a of the pouring cylinder 64 in a point shape from the outside in the vertical direction (contact in a linear direction in the circumferential direction) to seal. To do.

On the other hand, in the hinge cap 80 of the second conventional example as shown in FIGS. 15 and 16, as shown in FIGS. 15 and 18, the inner ring 88 has a relatively large size (longer) from the top surface 87 of the upper lid 82. ) It is formed to hang down. Therefore, the inner ring 88 of the upper lid 82 seals the pouring cylinder 84 linearly from the inside in the vertical direction (contacts in a planar direction in the circumferential direction) when the upper lid 82 is closed.

In the hinge cap 60 of the first conventional example, the injection cylinder 64 of the main body 61 is formed at the same height in the circumferential direction so as to stand relatively large (high) above the partition wall 66. When the upper lid 62 is opened and the contents are taken out, the contents can be taken out satisfactorily regardless of the direction in which the container is tilted. Further, when opening the upper lid 62, the contents may adhere to a portion near the thin wall portion 65 or the inside of the base end portion (lower end portion) of the dispensing cylinder 64, but the hinge cap 60 has the upper lid. When the 62 is closed, the tip portions of the inner ring 68 and the outer portion 69 are separated from the thin wall portion 65 and the base end portion (lower end portion) of the dispensing cylinder 64, so that when the upper lid 62 is opened, the upper lid 62 is opened. The contents adhering to the vicinity of the thin wall portion 65 and the base end portion (lower end portion) of the dispensing cylinder 64 hardly adhere to the inner ring 68 and the tip end portion of the outer portion 69, and the contents adhere to the inner ring 68 and the inner ring 68. It hardly hangs down from the outer portion 69.

However, in the hinge cap 60 of the first conventional example shown in FIGS. 13 and 14, the pouring cylinder 64 of the main body 61 is erected relatively large (high) above the partition wall 66 with respect to the circumferential direction. Since they are formed at the same height, the inner ring 68 and the outer portion 69 of the upper lid 62 cannot be formed long with a large size, and must be shortened. That is, as shown in FIGS. 19 to 21, for example, when the inner ring 68'of the upper lid 62 is formed long, when the upper lid 62 is closed, the inner ring 68'of the upper lid 62 is attached to the dispenser cylinder 64 of the main body 61. It interferes and the upper lid 62 cannot be closed satisfactorily.

In the hinge cap 60 of the first conventional example shown in FIGS. 13 and 14, the inner ring 68 and the outer portion 69 of the upper lid 62 are formed short so as not to cause such a problem. However, for this reason, in the hinge cap 60 of the first conventional example, the sealing area of the upper lid 62 by the inner ring 68 and the outer portion 69 with respect to the dispensing cylinder 64 when the upper lid 62 is closed is small, and the sealing performance is not very high. Therefore, for example, the contents are easily separated vertically, and when the container is shaken before use (so-called shuffle) in order to homogenize the separated contents, the dispenser cylinder is used. The contents may leak to the outside of the pouring cylinder 64 by passing between the 64 and the inner ring 68 or the outer portion 69.

On the other hand, in the hinge cap 80 of the second conventional example shown in FIGS. 15 and 16, the size of the inner ring 88 of the upper lid 82 is relatively large (long), so that the inner ring 88 when the upper lid 82 is closed The sealing area between the and the pouring cylinder 84 is large, and the sealing performance is good. Therefore, for example, when the contents are easily separated into upper and lower parts, even when the container is shaken before use (so-called shuffle), the container passes between the dispenser tube 84 and the inner ring 88. There is an advantage that the contents hardly leak to the outside.

However, in the hinge cap 80 of the second conventional example, since the size of the injection cylinder 84 is small and short on the side close to the hinge 83, a large amount of contents suddenly appear when the content liquid is to be discharged from the side close to the hinge 83. There is a risk of appearing in. That is, in the hinge cap 80 having such a structure, the direction in which the contents are put out is restricted. Further, since the size of the inner ring 88 of the upper lid 82 is relatively large (long), as shown in FIG. 15, the contents remaining on the upper surface of the outer peripheral portion of the partition wall 86 near the thin wall for breaking are the base end of the inner ring 88. It also adheres to the portion (lower end portion), and as shown in FIGS. 22 and 23, when the upper lid 82 is opened, the adhered content X is closer to the hinge at the base end portion (lower end portion) of the dispensing cylinder 84. It may be pulled up along the inner wall surface portion of the above, and the portion near the hinge on the upper surface portion of the main body 81 such as the outside of the dispensing cylinder 84 may be soiled.

The present invention solves the above problems, and the contents can be satisfactorily taken out regardless of the direction in which the container equipped with the hinge cap is tilted, and when the container is shaken before use (so-called shuffle). ) However, the contents rarely leak to the outside through between the dispenser and the inner ring, and the contents are rarely pulled up along the dispenser when the top lid is opened. It is intended to provide a cap.

In order to solve the above problems, the present invention is provided with a main body attached to the mouth of the container and an upper lid provided on the main body via a hinge, and when the contents in the container are poured into the main body. A pouring cylinder for guiding the contents and a partition wall formed inside the pouring cylinder and having a planned opening are provided, and the upper lid is provided with a lid plate, an outer peripheral surface continuous with the lid plate, and an upper lid. A hinge cap provided with an inner ring that closely seals the dispenser cylinder from the inside when closed, so that the tip of the dispenser cylinder is at the same height in the circumferential direction. It is extended upward in a tubular shape, and the hinge is placed at a position higher than the region away from the hinge at the outer peripheral joint where the outer peripheral portions of the upper lid and the main body join each other, and the upper lid is closed. The feature is that the tip of the inner ring is extended downward so that it is closer to the middle part between the base end and the tip than the base end and the tip of the pouring cylinder. To do.

According to the above configuration, the pouring cylinder is extended upward in a tubular shape so that the tip portion thereof is at the same height with respect to the circumferential direction, so that the container with the hinge cap attached can be tilted in any direction. However, the contents can be put out well. Further, with the upper lid closed, the tip of the inner ring extends downward so as to be closer to the middle part between the base end and the tip than the base end and the tip of the dispensing cylinder. Since it is removed, the sealing area between the dispensing cylinder and the inner ring with the upper lid closed can be increased, and good sealing performance can be obtained. Therefore, for example, when the contents are easily separated into upper and lower parts, even when the container is shaken before use (so-called shuffle), it passes between the dispensing cylinder and the inner ring to the outside. It is possible to almost prevent the contents from leaking out. Further, since the hinge is arranged at a position higher than the portion of the outer peripheral joint where the outer peripheral portions of the upper lid and the main body are joined and separated from the hinge, the tip of the inner ring is placed with the upper lid closed. Even if the portion is extended downward so as to be closer to the middle portion between the base end portion and the tip portion than the base end portion and the tip portion of the dispensing cylinder, the inner portion of the upper lid is closed when the upper lid is closed. It is possible to prevent the ring from interfering with the pouring cylinder of the main body, and the upper lid can be satisfactorily closed with respect to the main body.

Further, the dispensing cylinder of the present invention is formed so that the tip portion thereof expands in the radial direction, and the portion of the hinge that serves as the center of rotation of the upper lid is arranged at a position lower than the tip portion of the dispensing cylinder. It is a feature.

With this configuration, the pouring cylinder is formed so that the tip portion expands in the radial direction, and the tip portion of the inner ring with the upper lid closed is closer to the base end portion than the base end portion and the tip end portion of the dispensing cylinder. Even if it is extended downward so that it is close to the middle part in the middle with the tip part, it is possible to prevent the inner ring of the upper lid from interfering with the dispensing cylinder of the main body when closing the upper lid, and it is possible to prevent the main body The top lid can be closed well.

That is, by forming the dispensing cylinder so that the tip portion slightly expands in the radial direction, the contents can be ejected while being well guided by the dispensing cylinder. On the other hand, if the hinge is arranged so that the center of rotation of the upper lid is higher than the tip (upper end edge) of the dispensing cylinder, the tip (lower end) of the inner ring is placed when the upper lid is closed. ) Will rotate while moving toward the hinge side, so the part near the hinge at the tip (lower end) of the inner ring may strongly press the pouring cylinder outward in the radial direction, or the inner ring When the upper lid is closed because the part of the tip (lower end) away from the hinge is separated from the injection cylinder, it becomes difficult to make the inner ring adhere to the injection cylinder well. According to the configuration, the inner ring can be satisfactorily adhered to the pouring cylinder when the upper lid is closed without such a situation.

Further, the present invention is characterized in that a curved surface is formed inside the base end portion of the inner ring of the upper lid, which is curved diagonally inward and recessed. With this configuration, even if the contents may adhere to the inside of the base end of the inner ring when the container is shaken before use (so-called shuffle), the contents are transmitted along the curved surface. , It becomes easy to return to the inside of the pouring cylinder or the container.

Further, in the present invention, as an outer peripheral joint portion where the outer peripheral portions of the upper lid and the main body are joined to each other, a front horizontal joint portion extending horizontally rearward from the front end portion far from the hinge in a state where the upper lid is closed and viewed from the side, A rear inclined joint extending diagonally rearward from the rear end of the front horizontal joint and a rear horizontal joint extending horizontally from the rear inclined joint toward the portion where the hinge is provided are provided. The upper lid is provided with a wall for preventing liquid splashing that extends downward from the outer peripheral surface in the front region far from the hinge, and the rear end of the wall can be fitted to the main body in a stepped shape at the rear end of the front horizontal joint. It is characterized by being said to be. With this configuration, when the upper lid is closed, it can be closed while being well fitted to the main body.

According to the present invention, the dispensing cylinder is extended upward in a tubular shape so that the tip portion thereof is at the same height with respect to the circumferential direction, and the tip of the inner ring is the base of the dispensing cylinder with the upper lid closed. By extending the container downward so that it is closer to the middle part between the base end part and the tip part than the end part and the tip part, the contents can be tilted in any direction when the container with the hinge cap is tilted. It is possible to take out well, and it is possible to increase the sealing area between the pouring cylinder and the inner ring with the top lid closed, and it is possible to obtain good sealing performance, and shake the container before use. Even when it is (so-called shuffled), it is possible to almost prevent the contents from leaking to the outside through the space between the dispenser and the inner ring. Further, by arranging the hinge at a position higher than the region away from the hinge at the outer peripheral joint where the outer peripheral portions of the upper lid and the main body are joined, the tip of the inner ring can be moved with the upper lid closed. Even if it is extended downward so that it is closer to the middle part between the base end and the tip than the base end and the tip of the dispensing cylinder, the inner ring of the top lid will be opened when the top lid is closed. , It is possible to prevent interference with the pouring cylinder of the main body, and the upper lid can be closed satisfactorily with respect to the main body.

Further, since the rotation center of the upper lid on the hinge is arranged at a position lower than the upper end edge of the dispensing cylinder, the dispensing cylinder is formed so that the tip portion expands in the radial direction, and the upper lid is closed. Even if the tip of the inner ring is extended downward so that it is closer to the middle part between the base end and the tip than the base end and the tip of the dispensing cylinder, the upper lid is closed. At that time, it is possible to prevent the inner ring of the upper lid from interfering with the pouring cylinder of the main body, and the upper lid can be closed satisfactorily with respect to the main body.

As a result, the hinge cap 1 is attached to the container 2 in a state where the mouth 3 of the container 2 is sandwiched and fitted between the outer cylinder 12 and the inner cylinder 13 of the main body 4.

The operation unit 20 includes a support column 20a that stands up from the planned opening portion 18, and a pull ring 20b that is formed at the tip end portion of the support column 20a and for hooking a finger. In the unused state (unopened state) of the hinge cap 1, the opening 17 is closed by the planned opening portion 18, and the inside of the container 2 is kept in a closed state, as shown in FIG. Then, when the container 2 is used, the pull ring 20b is pulled up by the fingers, so that the thin wall 16 for breaking is broken and the planned opening portion 18 is separated from the cap body 4, and as shown in FIG. An opening 17 for ejecting the contents is formed.

In this embodiment, the breaking thin wall 16 has a thin wall shape in which a recess is formed on the lower surface side of the partition wall 15 (a groove recessed upward is formed), but the present invention is not limited to this. The thin wall may be formed by forming a recess on the upper surface side of the partition wall 15, or the thin wall may be formed by forming a recess on both the upper surface side and the lower surface side of the partition wall 15. Further, in this embodiment, the planned opening portion 18 and the opening 17 have a large circular shape at the center in a plan view, but the portion near the hinge 5 and the portion opposite to the hinge 5 are narrowed to the circular portion. The groove-shaped portions are connected so that a small amount of contents can be discharged from the narrow groove-shaped portion and a large amount of contents can be discharged from the circular portion. However, the shapes of the planned opening portion 18 and the opening 17 are not limited to this.

As shown in FIGS. 1 to 8, the upper lid 6 is provided with a lid plate 22 and an outer peripheral surface 21 continuous with the lid plate 22. Specifically, when the upper lid 6 is closed, the lower edge of the outer cylinder 12 of the cap body 4 comes into contact with the upper edge of the outer peripheral portion of the upper lid 6, and the locking cylinder 19 of the cap body 4 is brought into close contact with the upper lid 6 from the inside. The outer peripheral surface (also referred to as a skirt) 21, the lid plate 22 gently connected to the upper end edge of the outer peripheral surface 21, and the inside of the pouring cylinder 14 when the upper lid 6 is closed by projecting downward from the lid plate 22 in an annular shape. The inner ring (inner peripheral ridge) 23, which is closely sealed from the lid, and the outer ring surface 21 are formed so as to project laterally (front side) from a portion opposite to the hinge 5, and a finger or the like is formed at this portion when opening. A collar (also called a finger hook) 25 or the like that opens the upper lid 6 by hooking the lid 6 is provided. A recess 29 is formed in the portion of the main body 4 below the collar 25 when the upper lid 6 is closed, so that a finger can be easily hooked on the collar 25 of the upper lid 6.

In this embodiment, as shown in FIGS. 1 to 4, a wall that is continuous with the lower end of the outer peripheral surface 21 of the upper lid 6 and is continuous with the collar 25 in the circumferential direction (as described later, the liquid is (Also referred to as a splash prevention part) 26 is formed. The wall 26 is flush with the outer peripheral surface 21 of the upper lid 6 in the circumferential direction, and is provided so as to project downward from the lower end surface of the outer peripheral surface 21 of the upper lid 6. Further, the outer cylinder 12 of the main body 4 is provided with a storage recess 27 for accommodating the wall 26 when the upper lid 6 is closed, and the storage recess 27 is continuous with the collar 25 and the outer cylinder of the cap main body 4. It is formed on the outer peripheral surface of the outer cylinder 12 so as to cut out 12. The wall 26 is formed so as to cover the outer peripheral surface of the main body 4 when the upper lid 6 is closed. After the contents are poured out, the contents may collect on the upper end surface of the outer cylinder 12 of the main body 4. However, when the upper lid 6 is closed by the wall 26 of the upper lid 6, the outer cylinder of the main body 4 is collected. Even if the content liquid that has accumulated the contents on the upper end surface of the 12 bounces, the wall 26 is configured to receive the content liquid.

Here, as shown in FIGS. 1 to 6, the dispensing cylinder 14 is extended upward in a tubular shape so that the tip portion 14a thereof has the same height in the circumferential direction. Further, the hinge 5 is arranged at a position higher than the portion S of the region away from the hinge 5 in the outer peripheral joint portion 30 (in the state where the upper lid 6 is closed) where the outer peripheral portions of the upper lid 6 and the main body 4 are joined to each other. ing. Then, as shown in FIGS. 6 and 12, the tip end portion of the inner ring 23 is located at the base end portion 14b and the tip end portion of the dispensing cylinder 14 rather than the base end portion 14b and the tip end portion 14a with the upper lid 6 closed. It is extended downward so as to be at a position (height) close to the intermediate portion 14c in the middle of the portion 14a.

Further, the dispensing cylinder 14 is formed so that the tip portion 14a thereof slightly expands in the radial direction. Then, as shown in FIGS. 6 and 12, the portion 5A at the center of rotation of the upper lid 6 on the hinge 5 is higher than the position of the intermediate portion 14c of the dispensing cylinder 14, and is higher than the tip portion 14a of the dispensing cylinder 14. Is also placed in a low position. Further, a curved surface 28 is formed inside the base end portion 23b of the inner ring 23 of the upper lid 6 so as to be curved and recessed diagonally inward.

Further, as shown in FIGS. 1 to 8, the outer peripheral joint portion 30 (the outer peripheral joint portion 30A of the main body 4 and the outer peripheral joint portion 30B of the upper lid 6) is formed by joining the outer peripheral portions of the upper lid 6 and the main body 4 to each other. With the upper lid 6 closed and viewed from the side, from the front horizontal joint 31 (31A, 31B) extending horizontally from the front end far from the hinge 5 and the rear end of the front horizontal joint 31 (31A, 31B). The rear inclined joint 32 (32A, 32B) extending diagonally rearward and the rear horizontal joint 33 (32A, 32B) extending horizontally from the rear inclined joint 32 (32A, 32B) toward the portion where the hinge 5 is provided. 33A, 33B) and are provided. Further, as described above, the upper lid 6 is provided with a wall 26 for preventing liquid splashing extending downward from the outer peripheral surface thereof in the front region far from the hinge 5. The rear end portion 34B of the wall 26 can be fitted to the main body 4 (fitting portion 34A of the main body 4) in a stepped shape at the rear end portion of the front horizontal joint portions 31 (31A, 31B).

According to the above configuration, the pouring cylinder 14 is extended upward in a tubular shape so that the tip portion 14a thereof is at the same height in the circumferential direction, so that the container 2 to which the hinge cap 1 is attached can be placed. The contents can be put out well no matter which direction is tilted. Further, with the upper lid 6 closed, the tip end portion of the inner ring 23 is closer to the intermediate portion 14c between the base end portion 14b and the tip end portion 14a than the base end portion 14b and the tip end portion 14a of the dispensing cylinder 14. Since it is extended downward so as to be in the position, as shown in FIG. 12, it is good that the sealing area between the dispensing cylinder 14 and the inner ring 23 with the upper lid 6 closed can be increased. It is possible to obtain excellent sealing performance. Therefore, for example, when the content X is easily separated vertically, even when the container 2 is shaken before use (so-called shuffle), the space between the dispenser cylinder 14 and the inner ring 23 is maintained. It is possible to almost prevent the contents X from leaking to the outside through the passage.

Further, the hinge 5 is arranged at a position higher than the portion S of the region S away from the hinge in the outer peripheral joint portion 30 where the outer peripheral portions of the upper lid 6 and the main body 4 are joined to each other. Further, the dispensing cylinder 14 is formed so that its tip portion 14a expands in the radial direction, and the portion 5A at the hinge 5 which is the center of rotation of the upper lid 6 is higher than the position of the intermediate portion 14c of the dispensing cylinder 14. It is arranged at a position lower than the tip portion 14a of the ejection cylinder 14.

With this configuration, even if the tip end portion of the inner ring 23 is extended downward so as to be closer to the intermediate portion 14c than the base end portion 14b and the tip end portion 14a of the dispensing cylinder 14 with the upper lid 6 closed. When closing the upper lid 6, as shown in FIGS. 9 to 12, it is possible to prevent the inner ring 23 of the upper lid 6 from interfering with the dispensing cylinder 14 of the main body 4, and the upper lid 6 is attached to the main body 4. Can be closed well.

That is, the dispensing cylinder 14 is formed so that the tip portion 14a slightly expands in the radial direction, so that the content X can be ejected while being well guided by the dispensing cylinder 14. On the other hand, if the hinge 5 is arranged so that the center of rotation of the upper lid 6 is higher than the tip (upper end edge) of the dispensing cylinder 14, the inner ring 23 will be closed when the upper lid 6 is closed. Since the tip (lower end) rotates while moving toward the hinge 5, the portion of the inner ring 23 near the hinge (lower end) moves the pouring cylinder 14 outward in the radial direction. When the upper lid 6 is closed due to strong pressing or when the portion of the tip (lower end) of the inner ring 23 away from the hinge 5 is separated from the injection cylinder 14, the inner ring is attached to the injection cylinder 14. Although it is difficult to bring the 23 into close contact with each other, according to this configuration, the inner ring 23 can be brought into good contact with the dispensing cylinder 14 when the upper lid 6 is closed.

Further, according to the above configuration, a curved surface 28 that is curved and recessed diagonally inward is formed inside the base end portion of the inner ring 23 in the upper lid 6. With this configuration, even if the content X may adhere to the inside of the base end portion of the inner ring 23 when the container 2 is shaken (so-called shuffled) before use, the content X can be used. It is easy to return to the inside of the pouring cylinder 14 and the inside of the container 2 along the curved surface 28, which makes it easy to use and hygienic.

Further, according to the above configuration, as the outer peripheral joining portions 30 (30A, 30B) where the outer peripheral portions of the upper lid 6 and the main body 4 are joined to each other, the front end portion far from the hinge 5 in the state where the upper lid 6 is closed and viewed from the side. The front horizontal joint 31 (31A, 31B) extending horizontally rearward from the rear, and the rear inclined joint 32 (32A, 32B) extending diagonally rearward from the rear end of the front horizontal joint 31 (31A, 31B). A rear horizontal joint 33 (33A, 33B) extending horizontally (horizontally toward the rear) from the rear inclined joint 32 (32A, 32B) toward the portion where the hinge 5 is provided is provided. There is. Further, the rear end portion 34B of the wall 26 can be fitted to the main body 4 (fitting portion 34A of the main body 4) in a stepped shape at the rear end portion of the front horizontal joint portions 31 (31A, 31B). With this configuration, when the upper lid 6 is closed, it can be closed while being well fitted to the main body 4, and the reliability of the hinge cap 1 can be improved.
