Description

  The present invention relates to a dispensing cap.

Conventionally, provided with a cap body that is attached to the mouth portion of the container in which the contents are stored, and a cap-like cylindrical lid body that is rotatably connected to the cap body via a hinge part, The cap body has a pouring tube that extends in a direction intersecting the cap axis and has a spout formed at the tip thereof, and a cap that is removably fitted to the spout is provided in the lid. Out caps are known.
By the way, in this way, the cap body has a cap body that is rotatable around the hinge portion, and a cap body that has a spout cylinder that extends in a direction intersecting the cap axis and has a spout formed at the tip thereof. The plug body may be caught on the dispensing tube only by the rotation operation around the hinge portion of the lid body with respect to the cap body, and it is difficult to smoothly open and close the spout with the plug body with little resistance. There was a problem.
Therefore, as means for solving such a problem, for example, in Patent Document 1 below, notches extending in the cap axial direction are formed in the respective portions of the peripheral wall portion of the lid that are continuous with the hinge portion from both sides in the cap circumferential direction. A configuration is proposed in which the plug body is moved forward and backward along the opening direction with respect to the spout by sliding the lid body with respect to the cap body while expanding and reducing the width of each notch by separately forming it. ing.
Further, for example, in Patent Document 2 below, an engagement is provided that includes a small lid that is pivotally coupled to a dispensing cylinder via a coupling hinge portion and has the plug, and the small lid projects from the lid. As the lid rotates around the hinge by engaging with the projecting piece, a configuration is proposed in which the engagement projecting piece rotates the small lid around the connecting hinge to open and close the spout. ing.
Japanese Patent Publication No. 7-59428 JP 2008-74470 A

However, in the former pouring cap, since the notch is formed in the peripheral wall portion of the lid, the lid cannot be sealed, and foreign matter may enter the lid from the outside through this notch. In addition, since the width of the notch is expanded and contracted, there is a possibility that a crack is likely to be generated in the lid body based on the notch.
In the latter pouring cap, since the spout is opened and closed by engaging the engaging protrusion with the small lid, there is a problem that the engaging protrusion and the small lid are easily plastically deformed.

  The present invention has been made in consideration of such circumstances, and the spout can be smoothly opened and closed with less resistance by the plug without sacrificing the hermeticity in the lid, and is durable. It aims at providing the extraction cap which can prevent a fall.

  In order to solve the above-described problems and achieve such an object, the pouring cap of the present invention includes a cap body attached to the mouth of a container in which contents are stored, and a hinge portion on the cap body. And a cap-shaped cylindrical lid body rotatably connected to the cap body, and a cap cylinder extending in a direction intersecting the cap axis and having a spout formed at the tip thereof. The cap has a pouring cap, and gradually extends toward the inner side in the cap radial direction from the open end side of the peripheral wall portion toward the top side of the lid body, and elastically deforms in the cap radial direction. An elastic projecting piece formed in a projecting manner is projected, and a plug body detachably fitted to the spout is projectingly provided on the elastic projecting piece.

In this invention, when the lid body is rotated around the hinge portion with respect to the cap body so as to be separated from the spout, the plug body is poured while the elastic protrusion is elastically deformed outward in the cap radial direction. It slides over the opening edge of the spout in the outlet tube, and the stopper is removed from the spout and the spout opens. Thereafter, the spout is opened by further continuing the rotation of the lid as described above.
Next, when the lid is rotated around the hinge portion with respect to the cap body so as to approach the spout, and the stopper is made to reach the opening edge of the spout cylinder, the elastic projecting piece is moved in the cap radial direction. The plug body slides on the opening edge of the dispensing tube and reaches the spout while being elastically deformed toward the outside of the tube. At this time, the elastic protrusion is restored and deformed inward in the cap radial direction, and the stopper enters the spout and closes the spout.
As described above, the elastic protrusion is elastically deformed in the cap radial direction as described above, so that the spout is opened and closed by the plug, so that the spout is resisted by the plug without sacrificing the sealing performance in the lid. It can be opened and closed smoothly with less, and the durability can be prevented from being lowered.

Here, the plug body may be formed in a convex curved shape whose thickness gradually decreases from the central portion toward the outer peripheral edge, and the outer peripheral edge may be connected to the elastic protruding piece without a step.
In this case, since the plug body is formed in the convex curved shape and the outer peripheral edge thereof is connected to the elastic projection piece without any step, the plug body is poured out when the spout is opened and closed with the plug body as described above. It will slide on the opening edge of the tube smoothly with little catching. Therefore, the opening / closing operability of the pouring cap can be improved, and the durability can be reliably prevented from being lowered.

The elastic protruding piece is connected to the distal end side of a connecting piece extending from the open end of the lid toward the outer side in the cap radial direction, and the connecting piece is folded back toward the inner side in the cap radial direction. Thus, the lid body may be arranged to enter from the open end side.
In this case, since the elastic protruding piece is connected to the tip end side of the connecting piece, the cap body, the hinge part, the lid, the connecting piece, and the elastic protruding piece can be integrally formed. A cap can be formed easily.

Furthermore, the elastic projection piece may be disposed in the lid body by fitting a fitting cylinder continuously provided on the open end side into the peripheral wall portion of the lid body.
In this case, since the elastic projection piece is disposed in the lid body by fitting the fitting cylinder into the peripheral wall portion of the lid body, the elastic projection piece is likely to come off from the lid body or become unstable. This makes it possible to prevent the elastic protruding piece from being easily and reliably fixed in the lid.

Furthermore, the hinge part and the elastic protrusion may be arranged on the same straight line extending along the cap radial direction.
In this configuration, the connecting piece is also arranged on the same straight line extending along the cap radial direction together with the hinge portion and the elastic protruding piece, and the cap main body, the hinge portion, the lid, the connecting piece, and the elastic protruding piece are provided. When the cap is integrally formed, the cap is placed in the open position with respect to the cap body, and the elastic cap is positioned outside the cap, that is, the pour-out cap in the unfolded state is made of gold. The direction in which the elastic projection piece is rotated with respect to the lid body after being molded in the mold can be made the same as the direction in which the lid body is rotated with respect to the cap body. The assembly process of the output cap can be simplified.

  According to the pouring cap according to the present invention, it is possible to smoothly open and close the pouring port with less resistance and prevent deterioration in durability without sacrificing the hermeticity in the lid body. .

An elastic protrusion 31 that extends and is elastically deformable in the cap radial direction is provided. The elastic protruding piece 31 gradually increases in the radial direction of the cap as it goes upward from the central portion in the cap axis O direction of the portion corresponding to the arrangement position along the circumferential direction of the cap on the inner peripheral surface side of the peripheral wall portion 30a. It is a plate-like body extending toward the inside. Further, the hinge portion 20 that connects the lid body 30 and the cap body 10 is disposed on the opposite side of the elastic protruding piece 31 with the cap shaft O interposed therebetween. In the illustrated example, a gap is provided between the elastic protrusion 31 and the inner surface of the top 30 c and the inner peripheral surface of the peripheral wall 30 a in the lid 30.

  On the surface of the elastic protrusion 31 that faces the spout, a plug 32 that is detachably fitted to the spout is provided. The plan view shape of the plug body 32 is the same as the plan view shape of the spout, and the sizes thereof are also equal to each other. In the present embodiment, the plug body 32 is formed in a convex curved surface shape whose thickness gradually decreases from the central portion toward the outer peripheral edge, and the outer peripheral edge is connected to the surface of the elastic protruding piece 31 without a step. That is, the plug body 32 does not have a flat surface that rises along the opening direction from the surface of the elastic protrusion 31 toward the inside of the spout, and is configured only by a convex curved surface.

  Further, the elastic protruding piece 31 is connected to the distal end portion 33a side of the connecting piece 33 extending from the open end 30b of the lid body 30 toward the outer side in the cap radial direction, and the connecting piece 33 is shown in FIG. By being folded back toward the inner side in the cap radial direction, the lid 30 is disposed so as to enter from the open end 30b side. As shown in FIG. 1, the elastic protruding piece 31 is projected on the upper end opening edge of the fitting cylinder 34 fitted in the peripheral wall portion 30 a of the lid 30, and the connecting piece is interposed via the fitting cylinder 34. It is connected to the tip 33a of 33. The distal end portion 33 a of the connecting piece 33 is connected to the lower end portion of the portion corresponding to the arrangement position along the circumferential direction of the cap of the spout on the outer peripheral surface of the fitting cylinder 34.

  Further, on the inner peripheral surface of the fitting cylinder 34, a second end that engages with the first engaging convex portion 13 c of the cap body 10 is provided at the lower end portion of the portion corresponding to the arrangement position of the spout along the circumferential direction of the cap. An engaging convex portion 34a is projected. In addition, the size in the cap radial direction of the outer peripheral edge portion 13a in the top wall portion 13 of the cap body 10 is equivalent to the sum of the thickness of the peripheral wall portion 30a of the lid 30 and the thickness of the fitting cylinder 34. Yes.

  Here, in the open end 30b of the peripheral wall portion 30a of the lid body 30, a notch portion 30d is formed at a portion corresponding to the arrangement position along the circumferential direction of the cap of the spout, and the inside of the notch portion 30d is formed. Further, the tip portion 33a of the connecting piece 33 folded back as described above is accommodated. Thereby, the lower end opening edge of the fitting cylinder 34 and the open end 30b of the lid 30 are located on the same plane. The connecting piece 33 is formed such that the tip 33a is thicker than the others. Further, in the state where the connecting piece 33 is folded as described above, the portion excluding the distal end portion 33a protrudes outward from the peripheral wall portion 30a of the lid body 30 in the cap radial direction. On the other hand, it is an operation piece 33b which can be operated when rotating around the hinge portion 20.

  Furthermore, in this embodiment, the hinge part 20, the connection piece 33, and the elastic protrusion 31 are arrange | positioned on the same straight line extended along a cap radial direction. And the above cap main body 10, the hinge part 20, the cover body 30, the connection piece 33, the fitting cylinder 34, and the elastic protrusion 31 are formed integrally.

  As described above, according to the pouring cap 1 according to the present embodiment, when the lid body 30 is rotated around the hinge portion 20 with respect to the cap body 10 so as to be separated from the pouring port, the elastic protruding piece 31 is formed. While being deformed elastically toward the outer side in the cap radial direction, the plug body 32 slides over the opening edge of the spout in the spout cylinder 12, and the plug body 32 comes out of the spout and exits the spout 12. Opens. Thereafter, the lid 30 is further continuously rotated as described above to open the spout as shown in FIG.
