  In the pouring cap described in the above-mentioned conventional document, the pouring hole is opened and closed by operating a protrusion provided on the outer peripheral surface of the movable lid with fingers. However, if container contents such as detergent adhere to the protrusion, fingers are likely to slip on the protrusion, and the cap operation becomes complicated, and a large force is required for the operation of the protrusion.

  This invention is made in view of the said situation, Comprising: It aims at providing the pouring cap which can open a pouring hole smoothly.

In order to solve the above-mentioned problems, the present invention provides a cap body having an assembly cylinder part attached to the mouth cylinder part of the container body and an insertion cylinder part arranged coaxially with the axis thereof, and an extraction hole is formed. A slide nozzle including a nozzle portion and a slide cylinder portion connected to the nozzle portion and slidably attached to the insertion cylinder portion of the cap body in the axial direction; and the insertion cylinder portion and the slide A cylindrical operation tube portion surrounding the moving tube portion, and a first inclined surface is formed on the outer peripheral wall surface of the fitting tube portion to slide the opening end portion on the cap body side of the operation tube portion. A second inclined surface is formed on the outer peripheral wall surface of the sliding tube portion to slide the opening end portion of the operation tube portion on the slide nozzle side, and the first inclined surface and the second inclined surface are formed. The inclination angle of the inclined surface with respect to the axis is substantially the same.
According to this configuration, by pushing the operation tube portion, the open end of the operation tube portion is slid on the inclined surface, and thereby the slide nozzle can be moved. Therefore, there is no need to pull up the slide nozzle with fingers when opening the dispensing hole, so fingers do not slip even if the contents of the container body adhere to the slide nozzle or the operation tube. Can be operated smoothly. And since the inclination angle with respect to the axis line L of the first inclined surface and the inclination angle with respect to the axis line of the second inclined surface are substantially the same, the force for pushing the operating tube portion 12 is applied to the first inclined surface.

Thus, by forming the first inclined surface and the second inclined surface as ribs that are plate-like members, the thickness of the portion where the first inclined surface or the second inclined surface is formed is different from the thickness of the portion. It can be prevented from becoming thicker than the part. Thereby, the defect at the time of injection molding can be made hard to produce, and it becomes the extraction cap which can be manufactured with a high yield.

It is preferable that at least three or more ribs are arranged at equal intervals in the circumferential direction of the axis.
By setting it as such a structure, even if it presses any position of the circumferential direction of an operation cylinder part, it becomes the extraction cap which can be operated to open an extraction hole smoothly. If at least two ribs are formed, it can be operated without any problem. When there are two ribs, it is preferable to arrange the ribs at symmetrical positions around the axis.

As shown in FIG. 3, a guide mark 15, which is an identification mark for guiding a position pressed by a finger during operation, is provided on the outer peripheral surface of the operation tube portion 12. The guide mark 15 is, for example, a pattern or a seal formed by printing or the like, and may be formed by selectively providing an uneven shape at the time of molding.

  The pouring cap 10 of the present embodiment having the above-described configuration moves the slide nozzle 13 upward by pressing the operation cylinder portion 12 from the outside in the “closed” state shown in FIG. It is designed to open. This operation will be described in detail below.

First, in the pouring cap 10 in the “closed” state shown in FIG. 1, the slide nozzle 13 attached to the cap body 11 is in the lower position. That is, the front end (open end) of the fitting cylinder part 11b of the cap body 11 abuts against the groove bottom wall 13g between the sliding cylinder part 13c and the inner cylinder part 13e of the slide nozzle 13 and is restrained. The tip of the valve body 14 provided inside the fitting cylinder portion 11b closes the extraction hole 13a of the nozzle portion 13b.
At this time, the opening end portions 12a and 12b on both sides of the operation tube portion 12 are disposed on the outer end sides of the first inclined surface 11s and the second inclined surface 13s, respectively. A space is formed between the portion 13c.

When the operation tube portion 12 of the pouring cap 10 in the “closed” state is pressed from the outside, the operation tube portion 12 made of a deformable material is elastically deformed into an elliptical shape, and the pressed portion is pushed inward. Then, since the 1st inclined surface 11s and the 2nd inclined surface 13s are formed in the outer peripheral wall surface of the cap main body 11 and the slide nozzle 13, respectively, the opening edge parts 12a and 12b of the operation cylinder part 12 are respectively 1st. The first inclined surface 11s and the second inclined surface 13s are in contact with each other, and move inward while sliding on these inclined surfaces.
Thereby, the operating force that presses the operating cylinder portion 12 is converted into a force that separates the cap body 11 and the slide nozzle 13 in the direction of the axis L by the first inclined surface 11s and the second inclined surface 13s. And since the operation cylinder part 12 has a certain amount of rigidity, the slide nozzle 13 is pushed up by the operation cylinder part 12 pushed inward.

  Here, in the extraction cap 10 of the present embodiment, the inclination angle α of the first inclined surface 11s with respect to the axis L and the inclination angle β of the second inclined surface 13s with respect to the axis L are substantially the same. . Therefore, the force for pushing the operation cylinder portion 12 is uniformly converted into the axial force on each of the first inclined surface 11s and the second inclined surface 13s. Thereby, the pressing force with respect to the operation cylinder part 12 can be efficiently used for the movement of the slide nozzle 13, and the slide nozzle 13 can be moved smoothly. When the angle of the inclination angle α with respect to the axis L of the first inclined surface 11s and the angle of inclination β with respect to the axis L of the second inclined surface 13s is set to about 30 ° to 60 °, particularly about 45 °, the operation tube portion Therefore, the distance (stroke) to push in 12 and the force to press the operation tube portion 12 are balanced, and the slide nozzle 13 can be moved more efficiently.

  In the present embodiment, as shown in FIG. 3, the guide marker 15 is formed at the central portion in the axis L direction of the outer peripheral surface of the operation cylinder portion 12, so that the user positions the guide marker 15 during the opening operation. It can be guided to operate by pressing with a finger. Then, by pressing the position of the guide mark 15, the distance from the pressing position of the operation tube portion 12 to the opening end portions 12a and 12b becomes equal, so that the first inclined surface 11s and the second inclined surface 13s Accordingly, the pressing force acting on the slide nozzle 13 becomes even, and the slide nozzle 13 can be pushed up more smoothly.

  The slide nozzle 13 pushed up by a predetermined distance by the operation tube portion 12 includes a projection portion 13f formed on the inner peripheral surface of the slide tube portion 13c, and a locking portion 11f formed on the outer peripheral surface of the fitting tube portion 11b. It is restrained in the upper position by the restraining mechanism consisting of This state is the “open” state shown in FIG. 2, and the contents of the container body 20 can be poured out from the opened dispensing hole 13a.

As shown in FIG. 2, in the pouring cap 10 in the “open” state, when the slide nozzle 13 moves, the valve body 14 is pulled out from the pouring hole 13 a and the pouring hole 13 a is opened. Further, since the fitting cylinder part 11b of the cap body 11 is sandwiched between the sliding cylinder part 13c and the inner cylinder part 13e of the slide nozzle 13, even if the finger is released from the operation cylinder part 12, FIG. The “open” state shown in FIG.
In order to return from the “open” state shown in FIG. 2 to the “closed” state shown in FIG. 1, the slide nozzle 13 may be pushed into the cap body 11. Thereby, the valve body 14 of the cap body 11 closes the pouring hole 13a, and the pouring cap 10 is in the “closed” state.

Therefore, unlike the conventional push-pull cap, the operation of pulling up the slide nozzle 13 with fingers is unnecessary, and even if the contents of the container body 20 are attached to the slide nozzle 13 or the operation tube portion 12, the fingers slide. Operation is not hindered.
Since the inclination angle α of the first inclined surface 11s and the inclination angle β of the second inclined surface 13s are substantially the same, the force that pushes the operation cylinder portion 12 is used for the movement of the slide nozzle 13 efficiently. The slide nozzle 13 can be pushed up. Therefore, according to the pouring cap 10 of this embodiment, the opening operation of the pouring hole 13a can be performed smoothly.

In the present embodiment, the first inclined surface 11s and the second inclined surface 13s are constituted by ribs 11d and 13d that are plate-like members. By setting it as such a structure, the 1st inclined surface 11s and the 2nd inclined surface 13s can be formed, without enlarging the thickness of the cap main body 11 and the slide nozzle 13 partially.
Therefore, there is no thick portion that tends to cause defects in the injection molding, so that the dispensing cap can be manufactured with high yield.

The rib 11d is formed over the top surface of the top wall 11c and the outer peripheral surface of the fitting cylinder portion 11b, and the rib 13d is formed over the back surface (lower surface) of the nozzle portion 13b and the outer peripheral surface of the sliding cylinder portion 13c. Yes. With this configuration, the ribs 11d and 13d support the cap body 11 and the slide nozzle 13 as a whole to increase the rigidity, so that they are high-strength and highly reliable dispensing caps.
In addition, the member which comprises the 1st inclined surface 11s and the 2nd inclined surface 13s is not restricted to a rib. For example, an annular tapered surface may be formed so as to surround the fitting cylinder portion 11b of the cap body 11 or the sliding cylinder portion 13c of the slide nozzle 13.

In the pouring cap 10 of the present embodiment, it is sufficient that two or more ribs 11d and 13d are provided, but when there are two ribs 11d or two ribs 13d, the two ribs 11d (13d) are It is preferable to arrange them at symmetrical positions with respect to the axis. Moreover, it is preferable to arrange | position the cap main body 11 and the slide nozzle 13 so that the rib 11d and the rib 13d may oppose in the axis line L direction.
With such a configuration, even if there are two ribs 11d and 13d each, the opening operation can be smoothly performed by sandwiching the operation tube portion 12 with two fingers.

Furthermore, in the extraction cap 10, it is preferable that three or more ribs 11d and 13d are provided, and the plurality of ribs 11d (13d) are preferably arranged at equal intervals in the circumferential direction of the axis L.
By adopting such a configuration, the opening end portions 12a and 12b of the operation tube portion 12 can be slid on the ribs 11d and 13d regardless of the position in the circumferential direction of the operation tube portion 12. The slide nozzle 13 can be pushed up reliably.
