JP, 11-9489, A

  By the way, when pouring out the contents, it is sometimes desired to change the pouring pattern such as the pouring amount or the momentum at the time of pouring according to the use situation. In such a case, it is possible to change the dispensing pattern by adjusting the pressing force on the container, but it is necessary to adjust the pressing force in order to obtain the intended dispensing pattern. In particular, when locally pouring into a narrow space, delicate adjustment is required, which is difficult to use.

  An object of the present invention is to solve such a problem, and it is possible to easily switch the pouring pattern of the contents, and it is possible to locally pour the contents even in a narrow place. The purpose is to provide a pouring cap that can.

The present invention provides a cap main body having an opening that is attached to the mouth of a container and communicates with the inside of the mouth, and a slit formed in an elastically deformable partition provided in the opening to release the container. In a pouring cap having a slit valve for pouring out contents,
A nozzle cap that has a nozzle located above the slit valve and is detachably attached to the cap body,
The nozzle cap is a pouring cap having a protrusion that abuts the partition wall at least inside the end portion of the slit.

  It is preferable that the partition wall has a circular shape having a central axis line that is coaxial with the central axis line of the nozzle, and the protrusion is an annular protrusion that surrounds the central axis line of the nozzle.

  It is preferable to have a first hinge that connects the cap body and the nozzle cap.

  It is preferable to have a lid detachably attached to the nozzle cap.

  It is preferable to have a second hinge that connects the nozzle cap and the lid.

  In the pouring cap of the present invention, since it has a nozzle cap that is detachably attached to the cap body while having a nozzle located above the slit valve, if the nozzle cap is attached, The contents can be poured locally. Further, since the nozzle cap has a protrusion that abuts the partition wall at least inside the end of the slit, and the degree of release of the slit can be reduced by this protrusion, the amount of contents to be poured out and the time of pouring You can suppress the momentum. Therefore, it is possible to effectively prevent the problem that the content is vigorously ejected from the nozzle. On the other hand, when it is desired to directly pour out the contents from the slit valve as in the conventional case, it is only necessary to remove the nozzle cap, so that the pour-out pattern can be easily switched.

  When the partition wall has a circular shape having a central axis line that is coaxial with the central axis line of the nozzle, and the protrusion is an annular protrusion that circulates around the central axis line of the nozzle, the same contents are obtained even if the container is tilted in any direction. Can be poured out.

  When the first hinge that connects the cap body and the nozzle cap is provided, the cap body and the nozzle cap can be integrally formed, so that the number of parts is reduced as compared with the case where these are provided separately. be able to. Further, even if the nozzle cap is removed from the cap body, the nozzle cap is held by the cap body, so there is no risk of losing the nozzle cap.

  Further, it is preferable to provide a lid that is detachably attached to the nozzle cap, and this can prevent dust and the like from adhering to the nozzle cap. When the lid is provided, it is preferable to provide the second hinge that connects the nozzle cap and the lid, and thus the lid can be provided without increasing the number of parts.

  The holding member 4 is made of synthetic resin in the present embodiment, and includes a donut-shaped bottom portion 4a and an inner peripheral wall 4b integrally connected to an inner edge of the bottom portion 4a. The outer peripheral surface of the bottom portion 4a is formed so as to fit with the inner peripheral surface of the cap body annular wall 2d. As a result, the slit valve 3 is held by the holding member 4 such that the base portion 3a is sandwiched between the lower surface of the cap body top wall 2e and the upper surface of the bottom portion 4a. Further, since the cap body annular wall 2d is located radially outside the base portion 3a and the inner peripheral wall 4b is located radially inside, the movement of the slit valve 3 in the radial direction is also restricted.

  The nozzle cap 5 includes a nozzle cap peripheral wall 5a located above the cap body peripheral wall 2a, and a nozzle cap top wall 5b is integrally connected to the upper end of the nozzle cap peripheral wall 5a. Further, a lower end of the nozzle cap top wall 5b is connected to a nozzle cap annular wall 5c whose lower end is detachably fitted and held on the outer peripheral surface of the cap body annular wall 2d and an upper end of the nozzle cap annular wall 5c. A nozzle cap top wall 5d extending horizontally and a tubular nozzle 5e extending upward from the nozzle cap top wall 5d are provided. The nozzle 5e is provided at a position where its central axis is coaxial with the central axis of the partition 3b (in the present embodiment, the central axis of the nozzle 5e and the central axis of the partition 3b with respect to the central axis O of the container P). Are the same).

  The lower end of the nozzle 5e is provided with a protrusion 5f protruding toward the partition wall 3b. The protrusion 5f of the present embodiment is provided as an annular protrusion that circulates around the central axis O (hereinafter, the protrusion 5f is also referred to as an annular protrusion 5f). As shown in the enlarged view of FIG. 1, the annular projection 5f is in contact with the partition wall 3b inside the end portion 3c1 of the slit 3c by slightly pushing it down. Note that the annular protrusion 5f has only to come into contact with the partition wall 3b at least inside the end portion 3c1 of the slit 3c. The outer portion may contact the partition wall 3b outside the end portion 3c1. An outer annular protrusion 5g that comes into contact with the upper surface of the cap body top wall 2e is provided radially outside the annular protrusion 5f.

  The lid 6 includes a lid peripheral wall 6 a located above the nozzle cap 5. A lid top wall 6b is integrally connected to the upper end of the lid peripheral wall 6a. A bulging portion 6c that abuts the tip of the nozzle 5e is provided in the center of the lower surface of the lid top wall 6b. The bulging portion 6c can be attached to and detached from the outer peripheral surface of the nozzle cap annular wall 5c on the radially outer side. A lid annular wall 6d that is fitted and held in is provided. The outer peripheral surface of the lid peripheral wall 6a is provided with a finger grip portion 6e protruding outward in the radial direction.

  Further, the cap body 2 and the nozzle cap 5 of the present embodiment are swingably connected by the first hinge h1 located directly below the finger rest 6e, while being integrally connected to the cap body peripheral wall 2a and the nozzle cap peripheral wall 5a. Has been done. Similarly, the nozzle cap 5 and the lid 6 are swingable by the second hinge h2 that is integrally connected to the nozzle cap peripheral wall 5a and the lid peripheral wall 6a and that faces the first hinge h1 with the central axis O interposed therebetween. It is connected to the. The cap body 2, the nozzle cap 5, and the lid body 6 of the present embodiment are made of synthetic resin, and when these are molded with a mold, they are arranged in series as shown in FIG. .

  In the case of the pouring cap 1 having such a configuration, when it is desired to locally pour out the contents, the lid 6 is opened by using the finger hook 6e, while the nozzle cap 5 is kept closed. And Then, when the body portion (not shown) of the container P is pressed, the contents of the container P are pressurized, whereby the partition wall 3b of the slit valve 3 is elastically deformed and the slits 3c are released, so that the contents are removed from the slits 3c. It passes through and is discharged from the nozzle 5e. In the present embodiment, the annular projection 5f abuts the partition wall 3b inside the end 3c1 of the slit 3c, and thus the degree of release of the slit 3c can be reduced, so that the contents from the nozzle 5e are removed. It is possible to effectively prevent the problem of vigorous ejection. Further, since the partition wall 3b is constantly pushed down by the annular projection 5f and the slit 3c is always open with a minute gap, the contents are fixed at the slits 3c and the contents are discharged from the slit valve 3. It is possible to effectively prevent the failure not to be performed. In the present embodiment, the outer annular protrusion 5g is in contact with the upper surface of the cap main body top wall 2e, and the distance between the annular protrusion 5f and the partition wall 3b is kept constant. Even if pressed, the pouring state does not change. Further, since the partition wall 3b is not strongly pressed by the annular projection 5f, there is no possibility of inadvertently deforming the slit valve 3.

  On the other hand, if a relatively large amount of the content is to be poured out, the nozzle cap 5 may be opened with respect to the cap body 2 and the content may be directly poured out from the slit valve 3. In this way, by selecting whether to open the lid body 6 or the nozzle cap 5, it is possible to easily switch the pouring pattern of the contents.

  The pouring cap according to the present invention is not limited to the embodiments described above, and may be variously modified within the scope of the claims, or may have other configurations added. Good. For example, the annular protrusion 5f in the present embodiment is in contact with the partition wall 3b over the entire circumference, but it may be partially provided in the circumferential direction so as to locally contact. Further, the partition wall 3b, the nozzle 5e, and the annular projection 5f of the present embodiment all have the same central axis line, but the present invention also includes those having a deviated central axis line. Further, although the annular protrusion 5f of the present embodiment is provided directly below the nozzle 5e, it may be provided so as to be offset to the outside or inside in the radial direction of the nozzle 5e. Further, the nozzle 5e is not limited to the one extending upward, but may be inclined (or only the tip end) entirely or may extend laterally. The lid 6 may be attached to the nozzle cap 5 with screws or may be attached with an undercut, and similarly, the nozzle cap 5 may be attached to the cap body 2 with screws. It may be attached by undercut. The lid 6 may be provided so as to cover only the nozzle 5e. The partition wall 3b of the slit valve 3 has substantially the same thickness as the upper portion of the base portion 3a in the present embodiment, but may be thinner than the upper portion of the base portion 3a.
