Description

  The present invention relates to a pouring cap and a liquid pouring tool including the same.

  Conventionally, a small liquid pouring tool containing various detergents, cosmetics, foods, etc. has been directly attached with a pouring cap in a container prestored with various detergents, cosmetics, foods, etc. The liquid contents contained in the container are poured out.

  Therefore, various measures are taken for the pouring cap in order to prevent the liquid content from flowing out with irregular fluctuations. For example, Patent Document 1 discloses a pouring spigot in which a plurality of outflow holes are provided at equal intervals so that air replacement can be easily performed when liquid content is poured out. Patent Document 2 discloses an inner plug member that reduces the momentum of the contents by causing the contents to collide with the inner surface of the top surface portion of the projecting cylindrical portion.

Japanese Patent Laid-Open No. 10-175658 JP 2010-6396 A

  On the other hand, the liquid content contained in the container generally contains various components. However, depending on the viscosity of the liquid content, it may be difficult to take out the liquid content, or a large amount of liquid content at a time. The contents may appear. Thus, in the liquid contents accommodated in the container, it may be difficult to stably pour out a certain amount.

  On the other hand, for example, in the spouting stopper described in the above-mentioned Patent Document 1, it is possible to prevent outflow accompanied by irregular fluctuations of the liquid contents at the time of pouring by performing air replacement. It is not easy to dispense the amount stably. In addition, in the inner plug member described in Patent Document 2, it is possible to reduce the momentum of the liquid content at the time of pouring by providing the projecting cylinder portion, but the projecting cylinder portion is more than the cap shaft than the spout portion. Therefore, the liquid content flowing out from the opening provided in the projecting cylinder part immediately reaches the spout part and is poured out. That is, even in the inner plug member described in Patent Document 2, it is not easy to stably pour out a certain amount of liquid contents.

  Accordingly, an object of the present invention is to provide a pouring cap and a liquid pouring tool that can eliminate the disadvantages of the above-described conventional technology.

  The present invention is a pouring cap that is used by being attached to the mouth portion of a container, and has a bottomed tubular spout portion, a bottom portion of the spout portion, and a tubular portion of the spout portion. And a plurality of outflow holes provided on the outer periphery of the protrusion or outside the outer periphery in plan view, and for allowing the liquid contents in the container to flow out into the groove. The distance d1 from the central axis of the protruding portion to the outer peripheral portion of the protruding portion and the distance d2 from the central axis to the inner peripheral surface of the cylindrical portion are expressed by the relation d1> d2. An extraction cap satisfying / 2 is provided.

  This invention provides the liquid extraction tool provided with the said extraction cap and the container in which the liquid content was accommodated.

  According to the pouring cap and the liquid pouring tool of the present invention, it is easy to visually recognize the pouring state by regulating the outflow path of the liquid content in the container, and the liquid content can be poured stably and easily. be able to.

  As shown in FIGS. 2 to 4, the pouring cap 1 protrudes from the bottomed tubular spout portion 10 and the bottom portion 16 of the spout portion 10, and is connected to the tubular portion 15 of the spout portion 10. A protrusion 11 that forms an annular groove 19 therebetween, and a plurality of outflow holes 12 a to 12 d that are provided on the outer peripheral portion 18 of the protrusion 11 and allow the lotion in the container 2 to flow into the groove 19. . The pouring cap 1 includes a mounting portion 13 that is provided at the lower portion of the spout portion 10 and is attached to the container 2, and a seal portion 14 that is provided inside the mounting portion 13 and seals the container 2.

The spout portion 10 includes a cylindrical portion 15 formed in a cylindrical shape and a bottom portion 16 provided inside the cylindrical portion 15.
As shown in FIGS. 2 and 3, the cylindrical portion 15 has a distance (radius) from the central axis (hereinafter, also simply referred to as “central axis”) X of the dispensing cap 1 in a plan view from the root portion. It is formed in a spreading shape that gradually increases toward the tip. Moreover, the cylindrical part 15 is formed so that thickness may become thin gradually toward a front-end | tip part from a root part. In the present embodiment, on the distal end side of the cylindrical portion 15, by making the curvature of the inner peripheral surface 15a larger than the curvature of the outer peripheral surface 15b, the cylindrical portion 15 is expanded toward the distal end portion, The thickness on the tip side is gradually reduced.
By forming the tubular portion 15 in a widening shape that spreads outwardly from the root portion toward the distal end portion, the makeup at the distal end of the tubular portion 15 is completed when the lotion is poured out. The water flow can be cut off. Further, by reducing the thickness toward the distal end, the distal end side is easily elastically deformed, and the distal end of the cylindrical portion 15 is easily sealed with the overcap 3 described later.

  The cylindrical portion 15 is preferably formed such that the height H1 in the central axis X direction is higher than the height H2 of the protruding portion 11 in the central axis X direction. The cylindrical portion 15 is preferably formed such that the height H1 in the central axis X direction is higher than the height H2 in the central axis X direction of the protruding portion 11 over the entire circumference. By making the height H1 of the cylindrical portion 15 in the central axis X direction higher than the height H2 of the protruding portion 11 in the central axis X direction, the cylindrical portion is slowly moved while visually recognizing the lotion flowing out from the outflow holes 12a to 12d. The tip 15 can be moved to the tip. In addition, the lotion easily joins from the plurality of outflow holes 12a to 12d.

  In the present embodiment, the cylindrical portion 15 has a height H1 in the central axis X direction that is longer than a distance d1 from the central axis X to the outer peripheral portion 18 of the protruding portion 11 (hereinafter also simply referred to as “distance d1”). It is formed as follows. The distance d1 is a distance from the central axis X to a base end on the outer peripheral surface 18a side of the outer peripheral portion 18 to be described later of the protrusion 11 in a direction orthogonal to the central axis X. The cylindrical portion 15 is formed such that the height H1 in the central axis X direction is longer than the distance d1 over the entire circumference. Furthermore, the cylindrical part 15 is formed in the same height H1 over the perimeter. By making the height H1 of the cylindrical portion 15 in the central axis X direction longer than the distance d1, it flows out from the outflow holes 12a to 12d as compared with the case where the height H2 of the protruding portion 11 in the central axis X direction is made higher. This makes it easy to visually recognize the lotion and adjust the outflow state of the above-described lotion. In addition, the lotion easily joins from the plurality of outflow holes 12a to 12d. Furthermore, by making the height H1 of the cylindrical portion 15 in the central axis X direction the same height over the entire circumference, the cylindrical shape regardless of the inclination direction of the liquid pouring tool 100 when the lotion is poured out. The lotion can be poured out from any part of the part 15 in the same manner.

  In the present embodiment, the height H1 of the cylindrical portion 15 in the central axis X direction is higher than the distance d1 over the entire circumference in the circumferential direction, but at least part of the height H1 is higher than the distance d1. May be. In the present embodiment, the height H1 of the cylindrical portion 15 in the central axis X direction is set to the same height over the entire circumference in the circumferential direction, but the height of the cylindrical portion 15 in the central axis X direction in the circumferential direction. H1 may have different heights. Moreover, although the cylindrical part 15 was formed in the spreading | diffusion shape which spreads outward from the root part toward the front-end | tip part, it spreads linearly toward outward from the root part toward the front-end | tip part. You may form in a shape and may form in the cylinder of the same diameter. Furthermore, the cylindrical part 15 is good also as an elliptical shape or a polygonal-pillar cylindrical shape in planar view.

  The bottom portion 16 is provided at the proximal end of the spout portion 10 and is disposed between the attachment portion 13 and the bottom portion 16. The bottom portion 16 is provided so as to be substantially orthogonal to the central axis X.

As shown in FIG. 2, the protruding portion 11 is connected to the bottom portion 16, and is formed to protrude upward from the upper surface 16 a of the bottom portion 16 in the central axis X direction. Further, in the protruding portion 11, the distance d1 and the distance d2 from the central axis X to the inner peripheral surface 15a of the cylindrical portion 15 satisfy the relational expression d1> d2 / 2. The distance d2 is a distance (hereinafter also simply referred to as “distance d2”) from the central axis X to the base end of the inner peripheral surface 15a of the cylindrical portion 15 in a direction orthogonal to the central axis X. When the distance d1 and the distance d2 satisfy the relational expression d1> d2 / 2, the protruding portion 11 has an annular groove portion 19 having a suitable width at a suitable position between the tubular portion 15 of the spout portion 10. Can be formed. Specifically, when the distance d1 and the distance d2 satisfy the relational expression d1> d2 / 2, the groove portion 19 can be suitably curved along the cylindrical portion 15, for example, When the liquid pouring tool 100 is tilted to pour out the lotion, the lotion flows in a curved manner toward the pouring position along the groove portion 19, and takes longer than when flowing straight. The position can be reached. Therefore, it becomes easy to visually recognize the pouring state of the lotion, and the pouring of the lotion can be performed stably and easily.
Further, it can be expected that the user feels that the lotion has a viscosity and improves the expectation of the effect of the lotion.

  The distance d1 is preferably 60% or more, and more preferably 70% or more, from the viewpoint that the ratio (d1 / d2) to the distance d2 causes the skin lotion to bend and flow out appropriately. Further, from the same viewpoint, it is preferably less than 100%, more preferably 90% or less. Specifically, it is preferably 60% or more and less than 100%, and more preferably 70% or more and 90% or less.

  Note that, in the dispensing cap 1 of the present invention, the distance d1 and the distance d2 may satisfy the relation d1> d2 / 2 only in a part of the cylindrical portion 15 in the circumferential direction. However, from the viewpoint of ensuring the effect of the present invention more reliably, an angle range in which the distance d1 and the distance d2 satisfy the relational expression d1> d2 / 2 is set to the entire circumference of the cylindrical portion 15. When the angle range when satisfying the above is 360 °, it is preferably 120 ° or more and 360 ° or less, more preferably 180 ° or more and 360 ° or less, and further preferably 240 ° or more and 360 ° or less.
