[0009] Hereinafter, the pouring member of the present invention will be described with reference to the drawings based on its preferred embodiments. FIG. 1 shows a container 1 provided with an embodiment of the pouring member of the present invention. The container 1 shown in FIG. 1 includes a container body 10 in which a liquid is stored, a pouring member 2 attached to the mouth portion 14 of the container body 10, and a lid cap 6 detachably attached to the pouring member 2. The container 1 of the present embodiment is a bottle container, and the container body 10 includes a body portion 13 having a bottom, and a mouth portion 14 having a through-hole (liquid flow path) communicating with the inside of the body portion 13. The body portion 13 of the present embodiment includes a gripping through-hole 12 penetrating the body portion 13 at a position away from the central axis of the mouth portion 14, and a gripping portion 11 forming the outer peripheral edge of the gripping through-hole 12.

[0010] The container body 10 of the present embodiment has a liquid storage space inside the body portion 13 including the gripping portion 11. The body portion 13 has a bottom, and by grounding the bottom on a horizontal plane, the container body 10 (container 1) can be made to stand independently. In the standing state, the height direction (central axis direction) of the container 1 coincides with the vertical direction, the mouth portion 14 is located above in the vertical direction, and is disposed opposite to the bottom of the body portion 13 in the same direction. In the standing state of the container 1 of the present embodiment, the central axis of the mouth portion 14 has an angle with respect to the vertical direction, but the central axis of the mouth portion 14 may be parallel to the vertical direction in the standing state of the container 1. In the former case, the central axis of the mouth portion 14 has an angle with respect to the central axis of the body portion 13, and in the latter case, the central axis of the mouth portion 14 coincides with the central axis of the body portion 13. Hereinafter, unless otherwise specified, the description of the container 1 of the embodiments shown after FIG. 1 shall be the description of the container 1 in the self-standing state. Also, the height direction (vertical direction) of the container 1 substantially coincides with the protruding direction of the nozzle portion 30 described later. The description of the pouring member 2 shall be the description in a state where the protruding direction of the nozzle portion 30 described later is made to coincide with the vertical direction. The protruding direction of this nozzle portion 30 is defined as the height direction Z of the pouring member 2.

[0011] The type of the liquid accommodated in the container 1 of the present embodiment is not particularly limited. Examples of the liquid include liquid hair care agents such as shampoo, hair conditioner, and hair rinse, liquid soaps such as body soap and hand soap, liquid detergents for clothes and tableware, softeners and bleaches, liquid detergents for bathroom and floor cleaning, liquid cosmetics, liquid beverages, foods, pharmaceuticals, engine oil, and the like. Also, a liquid with a high viscosity such as cream may be used. The liquid is accommodated in the accommodation space inside the container body 10.

[0012] The mouth neck portion 14 is a cylindrical portion having a liquid flow path inside, and is provided at the upper end portion of the container body 10. The flow path communicates with the inside of the body portion 13 of the container body 10. The mouth neck portion 14 has a container-side thread portion 14a formed on its outer peripheral surface (see FIG. 2). The container-side thread portion 14a and a lower thread portion 22a formed on the inner peripheral surface of the lower outer cylinder portion 22 described later are made to be threadable. Thereby, the pouring member 2 is detachably attached to the mouth neck portion 14.

[0013] A lid cap 6 is detachably attached to the pouring member 2 of the present embodiment (see FIGS. 1 and 2). The lid cap 6 of the present embodiment is a measuring cap for measuring a liquid. This lid cap 6 includes a bottomed cylindrical cap body 60 extending in the height direction Z in a state of being attached to the pouring member 2, and an annular flange portion 62 projecting outward in the radial direction of the cap body 60. A cap-side thread portion 63 is formed on the outer peripheral surface of an end portion of the cap body 60 on the side opposite to the bottom portion 61 in the height direction Z, that is, an end portion on the opening side of the bottomed cylinder. The cap-side thread portion 63 is engageable with an upper thread portion 21a formed on the inner peripheral surface of the upper outer cylinder portion 21, which will be described later. Thereby, the lid cap 6 is detachably attached to the pouring member 2. In the container 1 of the present embodiment, the liquid stored in the container body 10 can be injected into the lid cap 6 through a nozzle portion 30, which will be described later, and measured. The liquid after measurement is usually discharged to another place such as a washing machine.

[0014] The pouring member 2 of the present embodiment includes an outer cylinder portion 20 having an attachment portion for the neck portion 14, a nozzle portion 30 formed inside the outer cylinder portion 20 in the radial direction, an inner cylinder portion 23 located between the outer cylinder portion 20 and the nozzle portion 30, and a bottom wall portion 28 connecting the lower end edges of the inner cylinder portion 23 and the nozzle portion 30 (see FIGS. 1 to 9).

[0015] The outer cylinder portion 20 of the present embodiment forms the outer peripheral portion of the pouring member 2 and includes an upper outer cylinder portion 21 and a lower outer cylinder portion 22. Each of the upper outer cylinder portion 21 and the lower outer cylinder portion 22 has a substantially cylindrical shape, and the lower outer cylinder portion 22 is connected to the lower end of the upper outer cylinder portion 21. The upper edge portion of the upper outer cylinder part 21 forms an annular shape in plan view, and the outer diameter of the upper edge portion corresponds to the outer diameter of the annular flange portion 62 of the lid cap 6. On the inner peripheral surface of the upper outer cylinder part 21, an upper thread portion 21a that is screwed with the cap-side thread portion 63 is formed. The inner diameter of the upper outer cylinder part 21 corresponds to the outer diameter of the cap body 60. The pouring member 2 inserts the end portion on the opening side of the cap body 60 inside the upper outer cylinder part 21, and by screwing the cap-side thread portion 63 and the upper thread portion 21a together, the lid cap 6 is attached to the upper outer cylinder part 21.

[0016] In the lower outer cylinder part 22 of the present embodiment, the outer diameter and the inner diameter gradually increase as going downward in the height direction Z, and the lower part of the lower outer cylinder part 22 protrudes radially outward from the upper outer cylinder part 21 in plan view of the pouring member 2 (see FIG. 3). On the inner peripheral surface of the lower outer cylinder part 22, a lower thread portion 22a that is screwed with the container-side thread portion 14a is formed. The inner diameter of the lower outer cylinder part 22 corresponds to the outer diameter of the neck portion 14. The pouring member 2 inserts the neck portion 14 inside the lower outer cylinder part 22, and by screwing the container-side thread portion 14a and the lower thread portion 22a together, the neck portion 14 is attached to the lower outer cylinder part 22. That is, the lower thread portion 22a of the lower outer cylinder part 22 serves as an attachment portion for the neck portion 14.

[0017] The inner cylinder part 23 of the present embodiment has a substantially cylindrical shape with a lower end opening inclined obliquely with respect to the horizontal direction, and is located radially inside the outer cylinder part 20. The lower end of this inner cylinder part 23 has a height position on the side opposite to the notch portion 34 of the nozzle part 30 to be described later in the circumferential direction, which is higher than the height position on the side where the notch portion 34 is located (see FIG. 2). Also, the inner cylinder part 23 has a lower height in the circumferential direction at the portion opposite to the notch portion 34 of the nozzle part 30 than at the portion where the notch portion 34 is located (see FIG. 2). The inner cylinder part 23 protrudes downward from the lower outer cylinder part 22 on the side where the notch portion 34 is located in the circumferential direction (see FIG. 4).

[0018] The upper edge portion 24 of the inner cylinder portion 23 is connected to the outer cylinder portion 20 located radially outward of the inner cylinder portion 23. The inner diameter of the inner cylinder portion 23 corresponds to the outer diameter of the end portion on the opening side of the lid cap 6. In a state where the lid cap 6 is attached to the pouring member 2, the end portion of the lid cap 6 is inserted and disposed within the inner cylinder portion 23 (see FIG. 2). The outer diameter of the inner cylinder portion 23 corresponds to the inner diameter of the neck portion 14. In a mounted state where the pouring member 2 is attached to the neck portion 14, the neck portion 14 is disposed between the lower outer cylinder portion 22 of the outer cylinder portion 20 and the inner cylinder portion 23, and the inner cylinder portion 23 is inserted and disposed within the neck portion 14. In this mounted state, the outer peripheral surface of the inner cylinder portion 23 is brought into contact with the inner peripheral surface of the neck portion 14. In the pouring member 2 of the present embodiment, in the mounted state, the outer peripheral surface on the upper end side of the inner cylinder portion 23 is in close contact with the inner peripheral surface of the neck portion 14, thereby further improving the liquid sealing property.

[0019] The bottom wall portion 28 is located between the inner cylinder portion 23 and the nozzle portion 30 located radially inside the inner cylinder portion 23 (see FIGS. 3 and 5). The bottom wall portion 28 connects the lower end edges of the inner cylinder portion 23 and the nozzle portion 30, and defines the nozzle lower end opening 29 of the nozzle portion 30 (see FIG. 6). This bottom wall portion 28 has a substantially annular shape in a bottom view when viewed from below, and a liquid return opening 27 is formed at a portion where the notch portion 34 is located in the circumferential direction. The liquid return opening 27 is continuous with the notch portion 34 and the nozzle lower end opening 29.

[0020] The nozzle portion 30 is a cylindrical portion located radially inside the inner cylinder portion 23 and protruding upward from the bottom wall portion 28, and functions as a liquid flow path in the pouring member 2. That is, the nozzle portion 30 is used to pour liquid into the lid cap 6 which is a metering cap. The nozzle portion 30 of the present embodiment projects upward beyond the inner cylinder portion 23 and further from the upper outer cylinder portion 21. A nozzle lower end opening 29 is disposed at the lower end of the nozzle portion 30, and the space within the nozzle portion 30 communicates with the inside of the container body 10 (neck portion 14) through the nozzle lower end opening 29. The nozzle portion 30 is formed so as to surround the peripheral edge of the nozzle lower end opening 29.

[0021] The nozzle portion 30 has a nozzle lower end opening 29 at the lower end and a nozzle upper end opening at the upper end, and has a cylindrical shape in which both openings communicate with each other. The nozzle portion 30 of the present embodiment has a notch portion 34 formed along the height direction Z of the nozzle portion 30 in a part of the circumferential direction of the nozzle portion 30. In the present embodiment, the notch portion 34 and the nozzle upper end opening are continuous (see FIG. 5). Further, the notch portion 34 of the present embodiment reaches the lower end of the nozzle portion 30 and is continuous with the nozzle lower end opening 29.

[0022] The nozzle portion 30 of the present embodiment has a vertex P that is the highest in the height direction Z on the side opposite to the notch portion 34 in the circumferential direction (see FIG. 7). In a plan view of the pouring member 2, a vertical center line CLa that passes through the center of the pouring member 2 and bisects the width of the notch portion 34 passes through the vertex P of the nozzle portion 30 (see FIG. 3). The nozzle portion 30 has a nozzle back side portion 30b having the vertex P and a pair of side surface portions 33S, 33S that face each other with the back side portion 30b interposed therebetween. When the container 1 is tilted to pour out the liquid, the liquid flows along the inner surface of the nozzle back side portion 30b and toward the nozzle upper end opening. That is, the nozzle back side portion 30b serves as a main flow path through which the liquid flows in the pouring member 2. The nozzle back side portion 30b is within a range of 30° or less in an angular range centered on the vertical center line CLa passing through the vertex P. In the circumferential direction of the nozzle portion 30, the nozzle back side portion 30b is disposed opposite to the notch portion 34. Further, in the circumferential direction of the nozzle portion 30, the nozzle back side portion 30b and the pair of side surface portions 33S, 33S are connected in a U shape (see FIGS. 3 and 8). The side edge portions of the pair of side surface portions 33S, 33S define the notch portion 34 and the nozzle upper end opening.

[0023] The state when the pouring member 2 is viewed in cross-section along the vertical center line CLa in a plan view is also referred to as a "vertical center cross-sectional view" (see Fig. 7). That is, the vertical center cross-sectional view is a state where the pouring member 2 is viewed in cross-section along a plane along the vertical center line CLa and along the height direction Z. In the vertical center cross-sectional view, the outer cylinder portion 20 has a notch facing portion 20a facing the notch portion 34 and a notch non-facing portion 20b on the side opposite to the notch portion 34. In the outer cylinder portion 20, the notch facing portion 20a is the portion on the notch portion 34 side sandwiching the nozzle lower end opening 29 in the vertical center cross-sectional view. In the outer cylinder portion 20, the notch non-facing portion 20b is the portion on the nozzle back side portion 30b side sandwiching the nozzle lower end opening 29 in the vertical center cross-sectional view. The notch facing portion 20a and the notch non-facing portion 20b face each other in the circumferential direction of the outer cylinder portion 20.

[0024] When a virtual straight line VL1 passing through the lower end of the notch non-facing portion 20b and the lower end of the nozzle back side portion 30b is assumed in the vertical center cross-sectional view, the virtual straight line VL1 passes obliquely upward through the notch portion 34. In the pouring member 2 of the present embodiment, in the vertical center cross-sectional view, the virtual straight line VL1 passes above the upper end of the notch facing portion 20a (see Fig. 7).

[0025] In the pouring member 2 of the present embodiment, in the vertical center cross-sectional view, since the virtual straight line VL1 does not interfere with the upper end or the upper outer cylinder portion 21 in the notch facing portion 20a and passes above the upper end, the nozzle lower end opening 29 can be easily visually recognized through the notch portion 34, and the inside of the neck portion 14 to which the pouring member 2 is attached can also be easily visually recognized. More specifically, when looking downward at the pouring member 2 through the notch portion 34, it becomes a line of sight generally along the virtual straight line VL1. In this case, since the upper outer cylinder portion 21 of the notch facing portion 20a, the lower end of the nozzle back side portion 30b, and the bottom wall portion 28 do not block the line of sight (virtual straight line VL1), the inside of the neck portion 14 in the mounted state of the pouring member 2 can be visually recognized. Such an effect is also referred to as an internal visual recognition effect. As a result, when refilling the liquid, it becomes easier to grasp the amount of the liquid S in the container body 10 through the notch 34 (see FIGS. 8(a) and (b)). Consequently, it is possible to effectively suppress a situation where an excessive amount of liquid exceeding the capacity of the container body 10 is injected and the liquid overflows from the pouring member 2. Thus, the pouring member 2 of the present embodiment is excellent in the operability of the injection operation.

[0026] From the viewpoint of further improving the internal visual recognition effect, when a virtual straight line VL5 inside the outer cylinder passing through the lower end of the notch non-opposing portion 20b and the upper end of the notch opposing portion 20a is assumed in the vertical center cross-sectional view, it is preferable that the inclination angle θ1 of the virtual straight line VL1 with respect to the horizontal direction is larger than the inclination angle θ5 of the virtual straight line VL5 inside the outer cylinder with respect to the horizontal direction (θ1 > θ5, see FIG. 7). In this case, in the vertical center cross-sectional view, the difference between the inclination angle θ1 of the virtual straight line VL1 with respect to the horizontal direction and the inclination angle θ5 of the virtual straight line VL5 inside the outer cylinder with respect to the horizontal direction is preferably 5° or more, more preferably 10° or more, and preferably 20° or less, more preferably 15° or less. Considering such a point, in the vertical center cross-sectional view, the difference between the inclination angle θ1 of the virtual straight line VL1 with respect to the horizontal direction and the inclination angle θ5 of the virtual straight line VL5 inside the outer cylinder with respect to the horizontal direction is preferably 5° or more and 20° or less, more preferably 10° or more and 15° or less.

[0027] From the viewpoint of further improving the internal visual recognition effect, the inclination angle is preferably within the following range.

Considering such points, the inclination angle θ5 of the virtual straight line VL5 inside the outer cylinder part with respect to the horizontal direction in the longitudinal center cross-sectional view is preferably 12° or more and 37° or less, more preferably 16° or more and 28° or less.

[0028] From the viewpoint of further improving the internal visual recognition effect, the area of the lower end opening 29 of the nozzle is preferably within the following range. The area of the lower end opening 29 of the nozzle is preferably 30% or more, more preferably 45% or more, and preferably 80% or less, more preferably 70% or less of the area of the lower end opening of the lower outer cylinder part 22.

The area of the lower end opening 29 of the nozzle is preferably 400 mm 2 or more, more preferably 700 mm 2 or more, and preferably 950 mm 2 or less, more preferably 900 mm 2 or less. Considering such points, the area of the lower end opening 29 of the nozzle is preferably 400 mm 2 or more and 950 mm 2 or less, more preferably 700 mm 2 or more and 900 mm 2 or less. When the lower end opening 29 of the nozzle is inclined obliquely with respect to the horizontal direction, it is the area in the inclined state.

[0029] From the viewpoint of further improving the internal visual recognition effect, the bottom wall part 28 is preferably inclined obliquely with respect to the horizontal direction (see Figs. 6 and 7). From the same perspective as above, the inclination angle θ3 (see Fig. 7) of the bottom wall portion 28 with respect to the horizontal direction is preferably 20° or more, more preferably 30° or more, and preferably 45° or less, more preferably 40° or less.
