The following embodiment shows one aspect of the present invention and does not limit the present invention, and can be arbitrarily changed within the scope of the technical idea of the present invention. Moreover, in the following drawings, in order to make each configuration easy to understand, the actual structure is different from the scale and number of each structure.

(First embodiment)
FIG. 1 is a vertical cross-sectional view of a top portion of an upright state of a container 1 to which a cap (hereinafter referred to as a nozzle cap) 6 according to the first embodiment is attached. The container 1 includes a container main body 2 that stores contents, a measuring cap 4 that is detachably attached to the outer side of the mouth part 3 located at the top of the container main body 2, and a middle plug that fits inside the mouth part 3. A nozzle cap 6 is provided.

The container body 2 is integrally formed by blow molding using, for example, an olefin synthetic resin such as polyethylene. The container body 2 is a container for storing, for example, liquid substances such as liquid detergents, liquid bleaches, liquid softeners, solvents, and granular materials such as granular detergents, granular bleaches, and granular seasonings. It has a space 2a. The mouth 3 of the container body 2 is formed in a cylindrical shape centering on an axis C extending in the vertical direction. The mouth 3 opens the storage space 2a upward. A male screw portion 3 a is formed around the axis C on the outer periphery of the mouth portion 3.

In the following description, a direction along the axis C is appropriately referred to as an axial direction, a direction perpendicular to the axis C is referred to as a radial direction, and a direction around the axis about the axis C is appropriately referred to as a circumferential direction. Moreover, the opening side of the mouth part 3 in the axial direction is appropriately referred to as the upper side (upper side), and the inner side of the bottle of the mouth part 3 is appropriately referred to as the lower side (lower side). In addition, the axial direction is set as the Z direction, the right and left direction in FIG. 1 is set as the X direction, and the Z direction and the direction orthogonal to the X direction (the direction orthogonal to the paper surface in FIG. 1) are appropriately described as the Y direction.

The nozzle cap 6 is formed by injection molding using an olefin synthetic resin such as polypropylene, for example. The nozzle cap 6 has an inner cylinder part 31, a flange part 32, a bottom wall part 33, a nozzle 34 and a guide wall part 55. The inner cylinder portion 31 extends around the axis C and is inserted inside the mouth portion 3.

FIG. 2 is a plan view of the nozzle cap 6 viewed from above, and FIG. 3 is a right side view. FIG. 4 is a bottom view of the nozzle cap 6 as viewed from below. FIG. 5 is a perspective view of the nozzle cap 6 as viewed from the lower left side (−X side and −Z side). The inner cylinder part 31 is located on the upper side and is fitted into the inner peripheral surface of the mouth part 3 in a press-fitted state, and is formed in a tapered shape that is located below the fitting part 31a and is tapered. Thus, it has a mouth part 3 and a separating part 31b that is spaced apart with a gap. A through hole 51 that penetrates the inner cylinder portion 31 is formed in the separation portion 31b at a position that intersects the X axis at + X in the circumferential direction and in the vicinity of the bottom wall portion 33 in the Z direction. The flange portion 32 engages with the upper end of the mouth portion 3 from above when the inner cylinder portion 31 is inserted into the mouth portion 3.

As shown in FIG. 1, the bottom wall 33 is located between the axis C and the through hole 51 in the X-axis direction and has a region extending in the Y-axis direction as a lowermost portion, and from the end in the X-axis direction to the lowermost portion. It has the inclination part 52 which inclines gradually as it goes to. The bottom wall 33 has a hole 36. The hole 36 penetrates the bottom wall 33 and opens in a space surrounded by the nozzles 34 on the upper side, as shown in FIG. The hole 36 is formed in a substantially rectangular shape in plan view, and a part thereof extends to the + X side and reaches the lowermost portion of the inclined portion 52.

The nozzle 34 protrudes upward from the inclined portion 52 in the bottom wall portion 33 and extends in a bowl shape with a U-shaped cross section opening to the + X side. Inside the nozzle 34, a guide surface 53 for guiding the dispensing of the contents (content liquid) stored in the storage space 2a is formed. The guide surface 53 is formed so as to surround the hole 36. A bulging portion 35 that bulges toward the −X side is formed at the circumferential center of the nozzle 34 (intersection with the X axis). At the center in the circumferential direction of the guide surface 53 (intersection with the X-axis), a bulging portion 35 is formed with a groove whose cross section is curved in a concave shape.

The guide wall portion 55 is formed so as to protrude downward from the bottom wall portion 33. The guide wall 55 protrudes along the outer shape of the hole 36 and in a rib shape surrounding the entire periphery of the hole 36. The lower end portion of the guide wall portion 55 is formed in parallel with a plane orthogonal to the axis C. Therefore, when the guide wall 55 is placed on the lower side and placed on a horizontal plane, the axis C is parallel to the vertical direction.

Of the inner peripheral surface of the guide wall 55, the surface located on the −X side, that is, the surface facing upward when the nozzle 34 is tilted with the −X side facing down, is the content stored in the storage space 2a. It is the 2nd guide surface 56 for guiding extraction of a thing (content liquid). The second guide surface 56 is formed flush with the guide surface 53 of the nozzle 34. In other words, the second guide surface 56 is formed in a shape in which a part of the guide surface 53 is extended downward.

The measuring cap 4 is formed by injection molding using an olefin synthetic resin such as polypropylene. The measuring cap 4 is provided with a covered cylindrical measuring portion 41 that enters the inner cylinder portion 31 so as to accommodate the nozzle 34 from above, and a cylinder that is provided on the radially outer side of the intermediate portion in the axial direction of the measuring portion 41. And a flange portion 43 that extends radially inward from the upper end portion of the outer cylinder portion 42 and is connected to the outer peripheral surface of the measuring portion 41.

The measuring cap 4 includes contents such as detergent injected with the opening of the measuring unit 41 facing upward, and a measuring scale marked by marking or printing on the outer peripheral surface or inner peripheral surface of the measuring unit 41 (see FIG. (Not shown) can be visually recognized.

The operation | movement which pours out the content is demonstrated using the container 1 with which the nozzle cap 6 of the said structure was mounted | worn.
As shown in FIG. 6, the container 1 with the measuring cap 4 detached from the mouth 3 is tilted so that the tip of the nozzle 34 faces downward with the bulging portion 35 positioned on the lower side in the circumferential direction. As a result, the content S stored in the storage space 2 a of the container body 2 moves to the vicinity of the nozzle cap 6. When the liquid level of the content S becomes higher than the lowest position on the distal end surface of the guide wall 55, the content S gets over the guide wall 55 and flows into the second guide surface 56.

Even when the measuring cap 4 is detached from the mouth part 3, the fitting part 31a of the inner cylinder part 31 is press-fitted into the inner peripheral surface of the mouth part 3, so that the nozzle cap can be used even when the container 1 is tilted. 6 is prevented from leaving the mouth 3.

The contents S that have flowed into the second guide surface 56 are sequentially guided to the second guide surface 56 and the guide surface 53 that are inclined downward, flow through the hole 36, and are rectified from the tip of the nozzle 34. For example, it is poured into the measuring cap 4. The contents S flowing on the second guide surface 56 and the guide surface 53 are smoothly guided and poured out without disturbing the rectification state because the second guide surface 56 and the guide surface 53 are flush with each other.

When the dispensing of the contents S is completed and the container 1 is erected, a part of the contents S remaining in the nozzle 34 and a part of the contents S remaining in the measuring cap 4 are bottoms. It flows to the lowermost part along the inclined part 52 of the wall part 33 and is collected in the storage space 2a through the hole part 36.

As described above, in the nozzle cap 6 according to the present embodiment, the content S in the storage space 2 a is projected from the bottom wall 33 toward the storage space 2 a of the container body 2 in addition to the guide surface 53 of the nozzle 34. Since the second guide surface 56 of the portion 55 is guided and rectified, the contents S can be stably poured out in a sufficiently rectified state without lengthening the nozzle 34. Therefore, by using the nozzle cap 6 of the present embodiment, it is possible to measure the contents S with high accuracy while preventing the overall height of the container 1 from increasing. In addition, in the nozzle cap 6 of the present embodiment, for example, when the content S is introduced from the nozzle 34 into the storage space 2a for refilling, the content S is in contact with the second guide surface 56 from the guide surface 53. Since it falls, compared with the case where the 2nd guide surface 56 is not formed, the refilling time of the content S can be shortened by the guidance effect.

Further, in the nozzle cap 6 of the present embodiment, since the tip end portion of the guide wall portion 55 is parallel to the plane orthogonal to the axis C, the nozzle cap 6 is along the horizontal plane with the tip end portion of the guide wall portion 55 facing down. The axis C can be made parallel to the vertical direction. Therefore, for example, when the inner cylinder part 31 of the nozzle cap 6 is gripped using a pair of robot arms that are separated and approached in the horizontal direction in the manufacturing process of the container 1, the outer peripheral surface of the inner cylinder part 31 is in the vertical direction. Since it extends along, the outer peripheral surface can be easily grasped.

Further, in the nozzle cap 6 of the present embodiment, the guide wall portion 55 is formed so as to be spaced inward from the outer periphery of the inner cylinder portion 31, and is formed so as to surround the entire periphery of the hole portion 36. Therefore, even when the nozzle cap 6 is dropped, it is difficult to directly contact the floor or the like, and damage to the guide wall portion 55 can be suppressed.

Furthermore, if the hole 36 is closed by the contents S when the container 1 is tilted, the storage space 2a becomes negative pressure as the contents S is poured out, and the dispensing speed may be reduced. However, in the nozzle cap 6 of the present embodiment, since the through-hole 51 is formed at a position on the upper side when the separation portion 31b of the inner cylinder portion 31 is poured, air between the storage space 2a and the outside is formed. A flow path can be secured. Therefore, in the nozzle cap 6 of the present embodiment, it is possible to avoid a decrease in the extraction speed caused by the negative pressure in the storage space 2a.

(Second Embodiment)
Next, a second embodiment of the nozzle cap 6 will be described with reference to FIGS. In these drawings, the same components as those of the first embodiment shown in FIGS. 1 to 6 are denoted by the same reference numerals, and the description thereof is omitted.

FIG. 7 is a perspective view of the nozzle cap 6 as viewed from the lower left side (−X side and −Z side).
As shown in FIG. 7, the nozzle cap 6 of the present embodiment is provided with a notch 57 locally at a position on the extraction side of the content S in the circumferential direction of the guide wall 55. Other configurations are the same as those of the first embodiment.

When the contents are poured out using the container 1 to which the nozzle cap 6 of this embodiment is attached, the liquid level of the contents S is tilted when the container 1 is tilted as shown by a two-dot chain line in FIG. When the liquid level of the content S becomes higher than the lowest position on the front end surface of the guide wall 55 after the content reaches the notch 57 and the content S flows into the second guide surface 56 from the notch 57, the content S gets over the guide wall portion 55 and flows into the second guide surface 56 with a time difference. Since the notch 57 is provided locally, the amount of the content S flowing into the second guide surface 56 from the notch 57 exceeds the guide wall 55 and flows into the second guide surface 56. Less than the amount. As a result, after a small amount of the content S is first poured out from the tip of the nozzle 34, a large amount of the content S is poured out with a time lag.

When the user tilts the container 1 and the time until the contents S are visually recognized is long, the tilt angle is increased and a large amount of the contents S may be poured out at once. When the container 1 with the nozzle cap 6 of the form is used, when the container 1 is tilted, a small amount of the content S is first poured out and can be visually recognized. Can be made larger than necessary. Therefore, in the nozzle cap 6 of this embodiment, it can avoid that the content S more than necessary is poured out and a measurement precision falls.

(Third embodiment)
Next, a third embodiment of the nozzle cap 6 will be described with reference to FIGS. 9 and 10. In these drawings, the same components as those of the first embodiment shown in FIGS. 1 to 6 are denoted by the same reference numerals, and the description thereof is omitted.

FIG. 9 is a plan view of the nozzle cap 6 according to the third embodiment viewed from above. FIG. 10 is a perspective view of the nozzle cap 6 according to the third embodiment as viewed from the lower left side (−X side and −Z side). The hole 36 in the nozzle cap 6 of the present embodiment is formed in a range surrounded by the outer shape of the guide surface 53 of the nozzle 34 and a straight line connecting one end in the circumferential direction and the other end in the circumferential direction of the guide surface 53. .

Further, the guide wall portion 55 projects in a rib shape that surrounds the outer shape of the hole portion 36 and surrounds the entire circumference of the hole portion 36. That is, in the nozzle cap 6 in the present embodiment, the planar view shape of the guide wall portion 55 includes the planar view shape of the nozzle 34.

For example, in the manufacturing process of the container 1, if a plurality of nozzle caps 6 having the guide wall portion 55 having an outer shape smaller than the outer shape of the nozzle 34 are stocked in a mixed state, the guide wall portion 55 enters the nozzle 34. Stacking can occur. In the nozzle cap 6 having the above configuration, since the planar view shape of the guide wall portion 55 includes the planar view shape of the nozzle 34, even when a plurality of nozzle caps 6 are mixed and stocked, stacking occurs. It becomes possible to suppress.

In addition to the above-described configuration shown in FIGS. 9 and 10, as a countermeasure against stacking of the nozzle cap 6, as shown in FIGS. 11 and 12, the guide surface 53 and the second guide surface 56 are provided with the nozzle 34. It is also possible to adopt a configuration in which a ridge 58 extending from the tip to the tip of the guide wall portion 55 is formed. By forming the ridges 58 on the guide surface 53 and the second guide surface 56, it is possible to more reliably prevent stacking from occurring when one of the nozzle 34 and the guide wall portion 55 enters the other.

As the protrusion 58, a structure formed on both sides of the center of the nozzle 34 in the width direction is preferable. By adopting this configuration, the contents S can be flowed and guided into the space between the ridges 58. Therefore, it can be expected that the rectification property for the contents S is further improved.

As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such examples. Various shapes, combinations, and the like of the constituent members shown in the above-described examples are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

For example, in the above-described embodiment, the configuration in which the nozzle 34 and the guide surface 53 have a U-shaped cross section is illustrated, but the present invention is not limited to this, and the V-shaped cross section or the U-shaped cross section (concave shape). There may be.

The present invention can be applied to a cap.
