Description

The present invention relates to a pouring cap.

Conventionally, as a spout cap mounted on the mouth of a container body filled with a highly viscous content liquid such as a liquid detergent or a liquid softener, there is a spout cap provided with a liquid recovery space between a spout cylinder and a peripheral wall. ..

When using this conventional pour cap to pour the content liquid of the container body, the outer peripheral surface of the pour tube of the pour cap is placed on the edge of the opening of the mating container and brought into contact therewith. Then, tilt the container body and pour the content liquid into the mating container from the spout of the spout cylinder. At this time, unless the contact position of the dispensing cylinder with respect to the counterpart container is stabilized, the content liquid cannot be smoothly dispensed. If the spout comes off the mating container, the liquid content will spill out of the mating container and stain the surrounding area.

Therefore, in the spout cap described in Patent Document 1, the outer peripheral surface of the spout barrel is positioned above the upper end of the peripheral wall portion of the spout barrel, and below the upper end of the spout barrel. A rib-shaped engaging portion is formed to protrude radially outward from a front center portion of the outer peripheral surface facing the liquid pouring direction. Thus, the rib-shaped engaging portion on the outer peripheral surface of the dispensing cylinder is locked to the edge portion of the opening of the mating container to stabilize the contact position of the dispensing cylinder with respect to the mating container. is there.

The pouring cap 100 of the present invention is attached to the mouth portion 2 of the container body 1. The dispensing cap 100 is covered with an upper lid so that it can be sealed in an external space. In this embodiment, the measuring cap 200 is applied as the upper lid.

In the present embodiment, the mouth portion 2 of the container body 1, the pouring cap 100, and the measuring cap 200 are assembled with their central axes arranged on the common axis O. Hereinafter, in a state in which the container body 1 is upright, the direction along the common axis O is the vertical direction, the side of the measuring cap 200 along the common axis O is the upper side, and the side of the container body 1 is the lower side. Further, when the container body 1 is tilted, the direction of pouring the liquid poured out from the pouring tube 10 of the pouring cap 100 is the front side, and the opposite direction is the rear side. That is, the left side of FIG. 3B is the front side and the right side is the rear side. Further, the direction along the common axis O is referred to as an axial direction, and the same applies when simply referred to as the axial direction in this specification.

As shown in FIGS. 1 to 4, the spout cap 100 is made of a synthetic resin molded body such as polypropylene, and has a beak-shaped spout barrel 10 capable of pouring a liquid. The pouring cap 100 is provided with a liquid recovery space 20 between the pouring cylinder 10 and the pouring cylinder 10 to surround the pouring cylinder 10, and a peripheral wall portion 40 connected to the pouring cylinder 10 via a bottom wall portion 30. In addition to having the outer cylindrical portion 50, the outer cylindrical portion 50 is connected to the axially intermediate portion of the peripheral wall portion 40 and surrounds the peripheral wall portion 40. The peripheral wall portion 40 is formed by connecting the upper tubular portion 41 and the lower tubular portion 42 at an axially intermediate portion, and the diameter of the lower tubular portion 42 is gradually reduced with respect to the upper tubular portion 41. The spout cap 100 has an outer tubular portion 50 that is coupled to the outer peripheral portion on the lower end side of the upper tubular portion 41 and surrounds the lower tubular portion 42. The bottom wall portion 30 is coupled to the lower end portion of the lower tubular portion 42. There is. The dispensing cap 100 fastens the inner peripheral fastening portion 51 of the outer tubular portion 50 to the outer circumferential fastening portion (not shown) provided in the mouth portion 2 of the container body 1 and measures the outer peripheral threaded portion 43 of the upper tubular portion 41. The inner peripheral threaded portion 211 provided on the outer tubular portion 210 of the cap 200 can be screwed.

In the dispensing cap 100, the dispensing cylinder 10 is erected from the bottom wall portion 30. The spout cylinder 10 is arranged such that its central axis substantially coincides with the common axis O, and the inside of the upper end portion thereof serves as a spout 11. Further, on the rear side of the pouring cylinder 10, a slit 12 is formed which penetrates the entire length in the vertical direction in the radial direction. The bottom wall portion 30 is gradually inclined downward from the front side toward the rear side. A communication port 31</b>A that opens in the surface of the bottom wall portion 30 is formed inside the lower end portion where the spout 10 is joined to the bottom wall portion 30. On the rear side of the communication port 31A in the bottom wall portion 30 and in the surface facing the liquid recovery space 20, a substantially rectangular shape connected to the communication port 31A and to the lower end of the slit 12 formed in the pouring tube 10 is formed. The liquid recovery port 31B is opened. The communication port 31A and the liquid recovery port 31B form an opening region 31 opened in the surface of the bottom wall portion 30.

The measuring cap 200 is made of a synthetic resin molding such as polypropylene (preferably a transparent body or a translucent body), and is a pouring cap provided at the mouth 2 of the container body 1 as shown in FIGS. 1 and 2. An outer cylindrical portion 210 having an inner peripheral threaded portion 211 that is screwed into the outer peripheral threaded portion 43 of the peripheral wall portion 40 in 100, and a bottomed cylinder having a cylindrical wall 221 and a bottom wall 222 inside the outer cylindrical portion 210. The inner cylindrical portion 220. The inner tubular portion 220 projects axially above and below the outer tubular portion 210. The inside of the inner tubular portion 220 serves as a liquid measuring space. The outer tubular portion 210 and the tubular wall 221 of the inner tubular portion 220 have their central axes coaxially arranged, and the inner tubular portion 220 has one end in the axial direction of the tubular wall 221 as an opening portion 221A, and the tubular wall 221 of the tubular wall 221 A bottom wall 222 is provided at the other end in the axial direction, and the other end is closed.

The measuring cap 200 has an annular wall 223 that closes between an end portion of the outer tubular portion 210 near the bottom wall 222 along the axial direction and an intermediate portion of the tubular wall 221 of the inner tubular portion 220 along the axial direction.

In the measuring cap 200, the bottom wall 222 of the inner tubular portion 220 is arranged on the upper side with respect to the outer peripheral threaded portion 43 of the peripheral wall portion 40 of the pouring cap 100 fitted in the mouth portion 2 of the container body 1 which is upright. In this state, the inner peripheral threaded portion 211 of the outer tubular portion 210 is attached and detached for use.

Therefore, when the liquid content of the container body 1 is poured out, the cylindrical wall 221 of the outer cylinder part 210 or the inner cylinder part 220 of the measuring cap 200 is gripped, and the measuring cap 200 is rotated in the circumferential direction, and the pouring cap 100 is discharged. At the same time as the removal, the spout barrel 10 of the spout cap 100 is exposed.

Next, the step is formed by arranging the central axis of the measuring cap 200 and the central axis of the pouring cap 100 so as to intersect with each other, and forming a protrusion 13 described later provided on the outer peripheral surface of the pouring tube 10 in the pouring cap 100. The portion 14 is locked to the edge of the opening 221A in the inner tubular portion 220 of the measuring cap 200. As a result, as shown in FIG. 7, in the state where the outer peripheral surface located above the projecting portion 13 of the dispensing cylinder 10 is brought into contact with the edge portion of the opening 221A of the measuring cap 200 so as to be in contact with the container body, as shown in FIG. 1 is tilted, and the content liquid is injected from the spout 11 of the spout barrel 10 into the inner cylinder portion 220 of the measuring cap 200 while being metered. Then, after that, the whole amount of the measured content liquid is poured out from the inner cylinder portion 220 of the measuring cap 200 to, for example, a washing machine, a washbasin, clothes and the like. When the pouring of the content liquid is completed, the container body 1 is raised and the measuring cap 200 is attached to the pouring cap 100 in the reverse order of the above.

When the container body 1 is raised after pouring out the content liquid, the liquid adhering to the inner surface of the pouring tube 10 at the time of pouring drips down the inner surface of the pouring tube 10 and the communication port 31A in the plane of the bottom wall portion 30. The liquid that returns from the inside of the container body 1 and drips along the outer periphery of the pouring cylinder 10 at the time of pouring drops in the liquid collecting space 20 and collects the liquid in the plane of the bottom wall portion 30 located at the deepest part thereof. Return from the mouth 31B to the inside of the container body 1.

In the pouring cap 100, if the lower end of the slit 12 formed in the pouring cylinder 10 reaches the bottom wall portion 30, it is not necessary to open the liquid recovery port 31B in the surface of the bottom wall portion 30, and after pouring out. The liquid accumulated in the liquid recovery space 2 can be recovered into the container body 1 from the slit 12 and the communication port 31A.

However, in the spout cap 100, as shown in FIGS. 2 to 4, the outer peripheral surface of the spout barrel 10 is located above the upper end of the peripheral wall portion 40 (upper tubular portion 41) of the spout barrel 10, and Below the upper end of the dispensing cylinder 10, there is a protrusion 13 having a step portion 14 extending in the circumferential direction on the outer peripheral surface of the dispensing cylinder 10. The outer peripheral surface 14A of the projecting portion 13 extends from the step portion 14 below the dispensing cylinder 10, and bulges forward from the outer peripheral surface 14B extending from the step portion 14 above the dispensing cylinder 10, The step portion 14 is formed at the boundary between the surface 14A and the outer peripheral surface 14B. The stepped portion 14 formed by the projecting portion 13 is stably engaged with the edge portion of the opening 221A in the inner tubular portion 220 of the measuring cap 200 into which the content liquid in the container body 1 is dispensed through the dispensing barrel 10. Can be stopped. In the present embodiment, the protruding portion 13 is provided in the central portion on the front side in the circumferential direction of the outer peripheral surface of the pouring tube 10, which faces the liquid pouring direction from the pouring tube 10. However, the protrusion 13 may be provided over the entire circumference of the outer peripheral surface of the spout barrel 10.

Therefore, when the content liquid in the container body 1 is poured into the measuring cap 200, as shown in FIG. 7, the step portion 14 formed in the protrusion 13 of the outer peripheral surface of the pouring cylinder 10 and extending in the circumferential direction is measured. Even if the container body 1 and the pouring cap 100 rotate to some extent around their central axes in a state of being locked to the edge of the opening 221A of the cap 200, a step extending in the circumferential direction of the projecting portion 13 The portion 14 does not slide down from the edge of the opening 221A of the measuring cap 200 to release the locked state. Therefore, the contact position of the dispensing cylinder 10 with respect to the measuring cap 200 can be reliably stabilized, and the dispensing work can be performed in a stable posture.

In the dispensing cap 100, at least a part of the inner peripheral surface of the peripheral wall portion 40, in the present embodiment, the inner peripheral surface 44 of the lower tubular portion 42 extends along a substantially vertical direction with respect to an inclination of the dispensing cap 100 in the axial direction. Let At the same time, the projecting portion 13 provided on the pouring tube 10 extends from the step portion 14 to the lower side of the pouring tube 10, and the projecting portion 13 is located at the central portion of the front side facing the liquid pouring direction from the pouring tube 10. Since the outer peripheral surface 14A of the projecting portion 13 is inclined in the axial direction of the spout cap 100, the inner peripheral surface 15 of the spout barrel 10 is formed in the axial direction of the spout cap 100. The inclination of the outer peripheral surface 14A is made closer to the vertical direction than the inclination made to. As a result, the outer peripheral surface 14A of the projecting portion 13 and the inner peripheral surface 44 of the peripheral wall portion 40 of the spout cylinder 10 are both oriented substantially in the vertical direction and are parallel to each other.

Therefore, the inner cylinder portion 220 of the measuring cap 200 is inserted into the liquid recovery space 20 between the peripheral wall portion 40 of the discharge cap 100 and the discharging cylinder 10 from the opening 221A side, and the measuring cap 200 is discharged. When screwed onto 100, the measuring cap 200 is substantially parallel between the inner peripheral surface 15 of the peripheral wall portion 40 of the spout cap 100 along the substantially vertical direction and the outer peripheral surface 14A of the spout barrel 10 along the substantially vertical direction. The inner cylindrical portion 220 is screwed while being guided within the interval. This makes it possible to easily obtain a correct screwed state without screwing the measuring cap 200 onto the dispensing cap 100 at an angle.

Further, as shown in FIGS. 3(C) and 4(B), the outer peripheral surface 14</b>B of the dispensing cylinder 10 located above the protruding portion 13 has a cross-section V that is orthogonal to the axial direction of the dispensing cap 100. It is bent in a letter cross section. When the V-shaped portion of the V-shaped cross section of the pouring cylinder 10 is provided in the central portion of the front side facing the liquid pouring direction from the pouring cylinder 10 in the circumferential direction of the pouring cylinder 10, this V-shaped part is poured out. Since the spout 11 formed inside the upper end of the cylinder 10 has a beak shape that faces the liquid pouring direction, the directivity of the pouring port 11 in the liquid pouring direction is improved.

However, when the content liquid of the container main body 1 is poured out by the measuring cap 200, the pouring cylinder 10 has the outer peripheral surface 14B of the V-shaped portion of the V-shaped cross section located above the protruding portion 13 of the measuring cap 200. It is easy to make contact with the edge of the opening 221A and to roll in the circumferential direction, and to make the contacting posture of the pouring cylinder 10 unstable. However, in the present invention, the protrusion 13 on the outer peripheral surface of the dispensing cylinder 10 forms a step 14 extending in the circumferential direction, and the step 14 of the protrusion 13 extends in the circumferential direction to a certain extent over a wide range. Since the cap 200 is locked to the edge of the opening 221A of the cap 200, the contact position of the dispensing cylinder 10 with respect to the measuring cap 200 can be reliably stabilized.

Therefore, even when the outer peripheral surface 14B of the V-shaped portion above the protruding portion 13 of the dispensing cylinder 10 comes into contact with the edge of the opening 221A of the measuring cap 200 and the dispensing cylinder 10 rolls easily, It is possible to stabilize the contact posture of the pouring tube 10 with respect to 200.

In addition, the outer peripheral surface 14A of the protruding portion 13 of the pouring tube 10 located near the step portion 14 is larger than that of the protruding portion 13 of the pouring tube 10 as shown in FIGS. 3(C) and 4(B). Also, the radius of curvature R (FIG. 4(B)) in the cross section orthogonal to the axial direction of the pouring cap 100 is set to be larger than that of the outer peripheral surface 14B located above.

As a result, the outer peripheral surface 14A of the projecting portion 13 forming the contour of the stepped portion 14 projects to the outside of the outer peripheral surface of the dispensing cylinder 10 with a greater roundness, and as a result, the outer periphery of the dispensing cylinder 10 The stepped portion 14 extends in a wider range in the circumferential direction of the surface. Therefore, in a state where the outer peripheral surface 14B above the protruding portion 13 of the pouring tube 10 is placed and abutted on the edge of the opening 221A of the measuring cap 200, which is the pouring destination, in contact with the container body 1 and the pouring cap. Even if 100 is rotated about its central axis to some extent, the stepped portion 14 extending in a wider range in the circumferential direction of the protruding portion 13 can be stably locked by the edge of the opening 221A of the measuring cap 200. The contact posture of the dispensing cylinder 10 with respect to the measuring cap 200 can be further stabilized.

The protruding portion 13 provided on the pouring tube 10 is further stepped outward from the step portion 14 below the pouring tube 10 a plurality of times in a staircase pattern so as to extend in the circumferential direction of the outer peripheral surface 14A of the pouring tube 10. You may form the several step part extended to. In addition, the projecting portion 13 reduces the amount of projection after projecting from the stepped portion 14 below the pouring tube 10, and also has a shape in which the projection is repeated, and unevenness is repeated in a so-called jagged or wavy shape. A plurality of stepped portions that extend in the circumferential direction of the outer peripheral surface 14A of the spout barrel 10 may be formed. As described above, by providing a plurality of step portions on the outer peripheral surface 14A below the step portion 14 of the dispensing cylinder 10, the user sets the outer peripheral surface of the dispensing cylinder 10 at the edge of the opening of the mating container. It becomes possible to adjust the mounting position.

As shown in FIG. 5, the spout cap 100 is a central portion on the front side of the outer peripheral surface of the spout barrel 10 facing the liquid spouting direction, and is an outer edge (upper end side) along the spout 11 at the upper end of the spout barrel 10. At the uppermost portion of the outer peripheral surface 14B), a liquid draining lip 11L that is inclined from the spout 11 to the outside in a curl shape is formed. Therefore, it is possible to prevent the liquid poured out from the pouring tube 10 from wrapping around to the outer surface of the pouring tube 10.

Further, during the pouring operation as shown in FIG. 7 in which the liquid content of the container body 1 is poured into the measuring cap 200, a step formed in the protruding portion 13 of the outer peripheral surface of the pouring cylinder 10 extending in the circumferential direction. When the container body 1 and the pouring cap 100 are pulled toward the user from the state where the portion 14 is locked to the edge of the opening 221A of the measuring cap 200, the outer edge of the upper end portion of the pouring cylinder 10 is The formed liquid draining lip 11L is locked to the inner side surface of the edge of the opening 221A of the measuring cap 200, so that the pouring barrel 10 is unlikely to drop from the edge of the opening 221A of the measuring cap 200. ..

Further, in the spout cap 100, as shown in FIG. 5 and FIG. 6, it extends in the circumferential direction of the peripheral wall portion 40 at each of a plurality of positions vertically separated from each other on the inner peripheral surface of the peripheral wall portion 40. A liquid drip prevention unit 70 is provided.

In addition, each of the first liquid drip prevention portion 71 and the second first liquid drip prevention portion 72 extends in a range of about a half circumference of the inner peripheral surface of the upper tubular portion 41 in the peripheral wall portion 40. Each of the liquid dripping prevention portions 71, 72 is located in the circumferential direction of the upper tubular portion 41 from the front center position C facing the pouring barrel 10 in the liquid pouring direction from the pouring barrel 10 and to the left and right of the central position C. It extends on both sides (S1, S2) by the same length on the left and right (FIG. 3(A), FIG. 5). The extension length of the first liquid drip prevention portion 71 on the lower side close to the bottom wall portion 30 is larger than the extension length of the second liquid drip prevention portion 72 on the upper side far from the bottom wall portion 30, as shown in FIG. The length is set to be short (the extension lengths of the protrusions a, c, and e are set to be long in that order).

Further, in the spout cap 100, as shown in FIG. 6, the inner peripheral surface of the peripheral wall portion 40 is closer to the bottom wall portion 30 than the liquid dripping prevention portions 70 (71, 72), and With respect to the first liquid dripping prevention unit 71 at the lowermost position, a distance G1 (distance G1 between the center lines of both liquid dripping prevention units 71 and 72) at which the liquid dripping prevention units 71 and 72 are separated from each other. A liquid dripping trap portion 60 extending in the circumferential direction of the peripheral wall portion 40 is provided at a position with a large gap G0 (a gap G0 between the center line of the first liquid dripping prevention portion 71 and the center line of the liquid dripping trap portion 60). It is provided.

In the present embodiment, the liquid dripping trap portion 60 is provided at one lower end portion of the inner peripheral surface of the upper cylinder portion 41 of the peripheral wall portion 40, and is formed by the liquid trap groove 60A extending in the circumferential direction of the upper cylinder portion 41. It The liquid catching groove 60A has a groove width and a groove depth larger than those of the liquid pooling grooves 71A and 72A of the liquid dripping preventing portions 71 and 72 described above.

Further, the liquid dripping catching portion 60 is located at the center from the above-mentioned front center position C facing the pouring cylinder 10 in the liquid pouring direction from the pouring cylinder 10 in the circumferential direction of the upper cylinder part 41 in the peripheral wall portion 40. It extends on both the left and right sides (S1, S2) of the position C (FIG. 3(A)), and its extension length is set longer than the extension length of each liquid dripping prevention portion 70 (71, 72). The liquid drip trapping portion 60 of the present embodiment extends over the entire circumference of the inner peripheral surface of the upper tubular portion 41 of the peripheral wall portion 40.

Therefore, in the spout cap 100, the following operational effects due to the provision of the liquid dripping capturing portion 60 and the liquid dripping prevention portion 70 are also exhibited.

(a) In the spout cap 100, liquid drip grooves 71A, 72A extending in the circumferential direction of the peripheral wall portion 40 are provided at each of a plurality of vertically spaced positions on the inner peripheral surface of the peripheral wall portion 40 to prevent liquid dripping. The section 70 (71, 72) is provided. Therefore, the liquid is continuously poured from the pouring cap 100, or when the liquid has a high viscosity, by raising the container body 1 after the liquid is poured, the liquid drops to the lower end side of the liquid recovery space 20 and collects. When the liquid that has been flowing out drips from the lower end side of the peripheral wall portion 40 along the inner peripheral surface of the peripheral wall portion 40 toward the upper end side of the peripheral wall portion 40 at the time of the next pouring, the liquid drops into a plurality of liquid drip prevention portions 70 (71). , 72) are sequentially taken into the liquid pool grooves 71A, 72A and their flow is stopped, and liquid dripping is prevented. This reduces the outflow amount of the liquid to the upper end side of the peripheral wall portion 40, and prevents the liquid from passing through the upper end of the peripheral wall portion 40 and wrapping around the outer peripheral surface thereof and adhering to the outer peripheral surface thereof.

When pouring the liquid from the pouring cap 100, the liquid that has passed over the liquid pool groove 71A of the first liquid dripping prevention unit 71 is prevented from dripping in the second liquid dripping prevention unit 72 or the like. The liquid is prevented from being dripped into the liquid collecting groove 72A of the portion 72 (the liquid drip preventing portion 72 on the upper side far from the bottom wall portion 30) and is reliably prevented from reaching the upper end of the peripheral wall portion 40.

At this time, the liquid pool grooves 71A and 72A of the liquid dripping prevention portion 70 (71, 72) provided on the inner peripheral surface of the peripheral wall portion 40 have uneven portions, concave portions, or concave and convex portions extending in the circumferential direction of the inner peripheral surface. It can be formed by a convex portion or the like, and is easily formed by a die that is punched out when forming the pouring cap 100. Therefore, with a simple structure, it is possible to prevent the content liquid from adhering to the outer peripheral surface of the peripheral wall portion 40.

(b) The extension length from the front center position C of the peripheral wall portion 40 in the lower first liquid dripping prevention portion 71 near the bottom wall portion 30 to both sides in the circumferential direction is the second upper portion far from the bottom wall portion 30. It is shorter than the circumferential length of the liquid dripping prevention portion 72. Therefore, after the liquid is prevented from dripping by the liquid dripping prevention portions 71 and 72 at the time of pouring the liquid from the pouring cap 100, the container body 1 is raised and the liquid accumulation grooves of the liquid dripping prevention portions 70 (71 and 72) are When the liquid taken in by 71A and 72A is hung down to the lower end side of the liquid recovery space 20 and is about to be returned to the container body 1, the liquid in the liquid sag prevention unit 72 on the upper side such as the second liquid sag prevention unit 72 The liquid dripping from the extended ends on both sides of the pool groove 72A passes through the sides of the extended ends on both sides of the liquid pool groove 71A of the lower liquid dripping prevention unit 71 such as the first liquid dripping prevention unit 71, and passes through them. The liquid dripping prevention portion 71 on the lower side hits and is not stopped and smoothly drips.

(c) The inner peripheral surface of the peripheral wall portion 40 is closer to the bottom wall portion 30 than the respective liquid spill prevention portions 70 (71, 72 ), and with respect to the first liquid spill prevention portion 71 at the lowest position. The liquid dripping catching portion 60 in which the liquid catching groove 60A extends in the circumferential direction of the peripheral wall portion 40 is provided at a position with a gap G0 larger than the gap G1 at which the liquid dripping preventing portions 71 and 72 are separated from each other. It is provided. Further, the liquid catching groove 60A of the liquid drooping catching portion 60 extends from the central position C of the peripheral wall portion 40 to both sides of the central position C, and the extension length thereof is each of the liquid drooping preventing portions 70 (71, 72). It is set longer than the extension length of the liquid pool grooves 71A and 72A.

Therefore, as described above, the liquid accumulated at the lower end side of the liquid recovery space 20 travels from the lower end side of the peripheral wall portion 40 along the inner peripheral surface thereof toward the upper end side of the peripheral wall portion 40 at the time of the next pouring. When dripping down, before the flow of the liquid reaches the plurality of liquid dripping prevention units 71 and 72, the liquid capturing groove 60A of the liquid dripping capturing unit 60 receives a part of the liquid and captures the liquid dripping. To do. As a result, the amount of liquid that flows out to the downstream side beyond the liquid dripping trap portion 60 and is taken in by the liquid pool grooves 71A and 72A of the liquid dripping prevention portions 71 and 72 located on the downstream side is reduced. Therefore, the liquid dripping prevention action of each liquid dripping prevention portion 71, 72 can be ensured.

The extension length from the front center position C of the peripheral wall portion 40 in the liquid dripping capturing portion 60 to both sides along the circumferential direction is longer than the extension length of each of the liquid dripping prevention portions 71 and 72 over the entire circumference in the circumferential direction, for example. .. Therefore, it is possible to surely reduce the amount of the liquid dripping trapped by the liquid dripping trap 60 over a long range along the circumferential direction of the peripheral wall 40 and to flow out to the downstream side of the liquid dripping trap 60.

Since the gap G0 between the liquid dripping prevention unit 60 and the first liquid dripping prevention unit 71 is larger than the gap G1 between the liquid dripping prevention units 71 and 72, the lower end of the liquid recovery space 20 at the time of the next pouring described above. The distance (the liquid arrival time) for the liquid accumulated on the side to get over the liquid dripping capturing unit 60 and reach the first liquid dripping prevention unit 71 increases. Therefore, the flow of the liquid, which has passed over the liquid dripping catching portion 60 and goes toward the first liquid dripping prevention portion 71 along the inner peripheral surface of the peripheral wall portion 40, is directed to the front side in the circumferential direction of the inner peripheral surface of the peripheral wall portion 40. It can be collected at the central position C. Thereby, even when each of the liquid dripping prevention portions 70 (71, 72) extends from the front center position C of the peripheral wall portion 40 to both sides along the circumferential direction, the liquid dripping capturing portion 60 is prevented. It is possible to collect a large amount of the liquid that has passed over toward the liquid dripping prevention region by the liquid dripping prevention units 71 and 72, and reliably stop the liquid by the liquid pool grooves 71A and 72A of the liquid dripping prevention units 71 and 72. Therefore, the effect of preventing liquid dripping by the liquid dripping prevention portions 71 and 72 can be ensured.

Further, in the spout cap 100, as described above, the spout 11 of the spout barrel 10 and the liquid recovery space 20 around the spout barrel 10 are opened in the plane of the bottom wall portion 30 in the opening region 31. It communicates with the inside of the container body 1 via (the communication port 31A and the liquid recovery port 31B). At this time, in the present embodiment, the opening region 31 occupies 40% or more of the total area of the bottom wall portion 30 including the opening region 31.

Therefore, at the time of refilling, the liquid supplied from the refill container can be efficiently stored inside the container body 1. Further, the liquid remaining in the spout cylinder 10 and the liquid recovery space 20 after the liquid is spouted can be efficiently recovered in the container body 1 through such a large opening region 31. As a result, the remaining amount of the liquid accumulated in the liquid recovery space 20 after the liquid is poured out is reduced, and the liquid is collected from the lower end side of the liquid recovery space 20 through the inner peripheral surface of the peripheral wall 40 at the upper end of the peripheral wall 40 at the time of the next pouring. It is possible to reduce the outflow amount of the liquid dripping toward

According to the present invention, the outer peripheral surface of the pouring tube in the pouring cap can be placed on the edge of the opening of the mating container and stably abutted thereon, and the pouring operation can be performed in a stable posture.
