  By the way, in the cap described in Patent Document 1, when the container body is tilted largely (for example, 90 ° or more) with respect to the vertical direction, the contents are surely brought into contact with the partition wall and the contents are evenly dispersed. There was a demand for further improvement in what to do.

  The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a cap that can evenly disperse contents even if the container body is largely tilted with respect to the vertical direction.

In order to solve the above problems, the present invention proposes the following means.
A cap according to the present invention includes a cap body attached to a mouth portion of a container body, and a capped cylindrical lid body, the cap body includes a top wall portion that covers the mouth portion of the container body, A surrounding wall portion extending upward from an outer peripheral edge portion of the ceiling wall portion; and an outlet opening through which a content is discharged, and an opening peripheral portion of the outlet opening, in the ceiling wall portion of the cap body. A lower partition wall extending toward the outer side in the radial direction of the cap is formed, and the lower partition wall is formed in a plurality in a circumferential direction along the periphery of the opening peripheral portion of the outflow opening in a top view, An outlet path is formed between the lower partition walls adjacent to each other, and at least one of the surrounding wall portion and the peripheral wall portion of the lid body is connected to a plurality of the outlet passages. A discharge hole is formed and the other opens and closes the discharge hole. A first engaging portion formed on one of the surrounding wall portion and the peripheral wall portion of the lid body, and a first engaging portion formed on the other side of the surrounding wall portion of the cap body and the lid body according to relative displacement in the vertical direction. It is characterized in that a second engaging portion for changing the opening height of the discharge hole is formed by combining them.

According to the cap of the present invention, the second engaging portion engages with the first engaging portion as the cap body and the lid body are displaced in the vertical direction. Therefore, in the process of changing the opening height of the discharge hole with relative displacement of the cap body and the lid in the vertical direction, the lower end of the peripheral wall portion of the lid body is above the upper end of the surrounding wall portion, and the lid body and the surrounding wall portion. It is possible to prevent the first engagement portion and the second engagement portion from engaging with each other by providing a gap with the wall portion separately from the discharge hole. As a result, the contents that have come into contact with the lower partition wall and passed through the outflow passage can be reliably discharged through the discharge holes, and the contents can be kept even if the container body is tilted largely with respect to the vertical direction. Can be sprayed.
Further, the opening height of the discharge hole is changed by the second engaging portion engaging with the first engaging portion. This makes it possible to adjust the discharge amount of the contents discharged from the discharge hole, and improve the convenience of the cap.

  A topped tubular guide member that guides the contents from the outflow opening to the outflow passage is erected on the opening peripheral portion of the outflow opening in the ceiling wall portion, and a plurality of the guide members are provided on the peripheral wall portion of the guide member. A plurality of communication holes that individually open toward the outflow passage may be formed at intervals in the circumferential direction.

  In this case, a plurality of communication holes are formed in the peripheral wall portion of the guide member at intervals in the circumferential direction. Therefore, when the container main body is largely tilted with respect to the vertical direction, the contents passing through the outflow opening can be guided from the top wall portion of the guiding member toward the peripheral wall portion to guide the communication hole. Thereby, for example, the content can be smoothly guided to the outflow passage as compared with a configuration in which the content that has passed through the outflow opening flows to the top wall portion of the lid body without the guide member. As a result, while ensuring the flowability of the contents, for example, it is possible to raise the lid or the surrounding wall portion in the vertical direction to form the discharge hole in a large size in the vertical direction, and to increase the opening height of the discharge hole. The range of changes can be expanded.

  The guide member is connected to an opening peripheral portion of the outflow opening in the ceiling wall portion via a flange portion protruding from a lower end of the guide member to a radial outside of the outflow opening, and the communication hole is the guide hole. It may be formed continuously with the member and the collar portion.

  In this case, the communication hole is formed continuously with the guide member and the collar portion. Therefore, for example, a large opening area of the communication hole can be secured, and the contents can be smoothly circulated in the outflow passage.

  An inner wall located between the peripheral wall portion of the guide member and the plurality of lower partition walls may be disposed on the top wall portion of the lid body.

  In this case, the middle wall is arranged on the top wall of the lid. Therefore, when the content passes through the outflow passage through the communication hole, the inner wall can suppress the excessive movement of the content toward the top wall of the lid. As a result, the contents can be smoothly distributed in the outflow passage.

  The discharge hole includes an outer discharge hole formed in a peripheral wall portion of the lid body and opened and closed by the surrounding wall portion, and the outer discharge hole is a top wall portion of the lid body in the peripheral wall portion of the lid body. It may be formed in a portion including a connecting portion with.

  In this case, the outer discharge holes are formed in the peripheral wall portion of the lid body at a portion including a connecting portion with the top wall portion of the lid body. Therefore, it is possible to prevent the contents passing through the outer discharge holes from being caught by the corners formed between the peripheral wall portion and the top wall portion in the lid, for example. Not leak can be suppressed. That is, if the contents are caught at the corners, the contents caught at the corners may unintentionally leak out when the tilted container body is erected.

  The second engagement portion includes an upper end engagement portion that restricts further upward movement of the lid body, and a peripheral wall portion of the lid body is formed with a recessed portion that is recessed downward. The engagement portion may be the bottom surface of the recess.

  In this case, since the upper end engaging portion is the bottom surface of the recess, it is possible to simplify the structure of the cap.

  The second engagement portion may include an intermediate engagement portion provided on a side surface of the recess.

  In this case, since the intermediate engaging portion is provided on the side surface of the recess, it is possible to further simplify the structure of the cap.

  According to the present invention, it is possible to provide a cap capable of suppressing the occurrence of unevenness in the amount of scattered contents when the container body is largely tilted with respect to the vertical direction.

The communication hole 36 is not covered by the inner wall 14 from the outside in the radial direction of the cap, and the communication hole 36 is fully opened. Further, the lower end portion of the front partition wall 16 is continuously sliding on the sliding surface 26d of the rear partition wall 26, and the lower end portion of the front partition wall 16 and the upper end portion of the rear partition wall 26 are However, they are close to or in contact with each other in the front-back direction.
As shown in FIG. 15, when the container main body 2 is tilted in a state where the first engaging portion 61 and the upper end engaging portion 62 a are in contact with each other, the contents pass through the communication hole 36 and the outflow passage 25 and the outer discharge hole 51. Is discharged from. At this time, the discharge amount of the content is larger than that in the state where the first engaging portion 61 and the intermediate engaging portion 62b are in contact with each other.

As described above, according to the cap 1 of the present embodiment, the second engaging portion 62 engages with the first engaging portion 61 as the cap body 20 and the lid body 10 are vertically displaced. Therefore, in the process of changing the opening height of the discharge hole 50 with relative displacement of the cap body 20 and the lid body 10 in the up-down direction, the lower end of the peripheral wall portion 12 of the lid body 10 moves upward from the upper end of the surrounding wall portion 29. The first engaging portion 61 and the second engaging portion 62 are engaged with each other to prevent a gap from being provided between the lid body 10 and the surrounding wall portion 29 separately from the discharge hole 50. be able to. As a result, the contents that have come into contact with the lower partition wall 24 and have passed through the outflow passage 25 can be reliably discharged through the discharge hole 50, and the contents can be retained even if the container body 2 is largely tilted with respect to the vertical direction. You can evenly spread things.
Further, the opening height of the discharge hole 50 is changed by the plurality of second engaging portions 62 engaging with the first engaging portion 61 separately. This makes it possible to adjust the discharge amount of the contents discharged from the discharge hole 50, and improve the convenience of the cap 1.

  Further, a plurality of communication holes 36 are formed in the peripheral wall portion 31b of the guide member 31 at intervals in the circumferential direction. Therefore, when the container body 2 is largely tilted with respect to the vertical direction, the contents that have passed through the outflow opening 23 are guided from the top wall portion 31a of the guide member 31 toward the peripheral wall portion 31b, and the communication hole 36 is guided. be able to. Thereby, for example, the content is smoothly guided to the outflow passage 25 as compared with a configuration in which the content that has passed through the outflow opening 23 flows to the top wall portion 11 of the lid body 10 without the guide member 31. can do. As a result, while ensuring the flowability of the contents, for example, the lid 10 or the surrounding wall portion 29 can be raised in the vertical direction to form the discharge hole 50 large in the vertical direction. The range of changing the opening height can be expanded.

Further, the communication hole 36 is formed continuously with the guide member 31 and the collar portion 35. Therefore, for example, a large opening area of the communication hole 36 can be secured, and the contents can be smoothly circulated in the outflow passage 25.
An inner wall 14 is arranged on the top wall 11 of the lid 10. Therefore, when the content passes through the outflow passage 25 through the communication hole 36, the inner wall 14 can suppress the excessive movement of the content toward the top wall portion 11 of the lid 10. Thereby, the contents can be smoothly circulated in the outflow passage 25.

  Further, the outer discharge holes 51 are formed in the peripheral wall portion 12 of the lid body 10 in a portion including a connecting portion with the top wall portion 11 of the lid body 10. Therefore, it is possible to prevent the content passing through the outer discharge hole 51 from being caught in a corner portion formed between the peripheral wall portion 12 and the top wall portion 11 in the lid 10, for example. Unintentional leakage of contents can be suppressed. That is, if the contents are caught in the corners, the contents caught in the corners may unintentionally leak out when the tilted container body 2 is made upright.

Further, since the upper end engaging portion 62a is the bottom surface 64a of the recess 64, the structure of the cap 1 can be simplified.
Further, since the intermediate engaging portion 62b is provided on the side surface 64b of the recess 64, the structure of the cap 1 can be further simplified.

  Further, when viewed from the front, the first engaging portion 61 and the second engaging portion 62 are disposed on both the left and right sides, so that the operating portion 18 is operated to move the lid body 10 upward with respect to the cap body 20. When the lid body 10 is rotated, for example, the lid body 10 is rotated upward with respect to the cap body 20 by more than a predetermined amount. Suppress it together. This stabilizes the posture of the lid body 10 when the lid body 10 is rotated upward with respect to the cap body 20, and the positional relationship between the lower partition wall 24 and the peripheral wall portion 12 of the lid body 10 in the vertical direction. Is stable, it is possible to more reliably prevent the content discharged from the outflow opening 23 from flowing out without contacting the lower partition wall 24.

  Further, in a state in which the first engaging portion 61 and the second engaging portion 62 are engaged with each other and the upward rotation of the lid 10 is suppressed, the lower end portion of the front partition wall 16 and the rear partition wall 26. Since the upper end portion is close to or abuts in the front-rear direction, it is possible to prevent the content discharged from the outflow opening 23 from entering the space on the rear side of the rear partition wall 26.
