Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when using the above-mentioned conventional pouring container, there may be a case where the content is desired to be poured to a desired place. However, for example, if the width of the entire pouring outlet is large due to factors such as a wide arrangement of a plurality of openings forming the pouring outlet, the content will be poured over a wide area, and it will be difficult to pour the content to a desired place. Further, when the opening provided in the top wall portion of the cap is used as the pouring outlet, it is difficult to visually recognize the pouring outlet when pouring, and it is difficult to pour the content to a desired place. For this reason, it is desired to be able to pour the content to a desired place. Further, even when a structure capable of pouring the content to a desired place is provided in the cap, it is desired that the cap is compact.

[0005] In view of such points, an object of the present invention is to provide a cap that can pour the content to a desired place and is compact.

Means for Solving the Problem

[0006] The cap is a cap comprising a cylindrical part attached to the mouth of a container body for storing contents, a top wall part covering the mouth opening on the upper surface of the mouth, and a lid part that opens and closes an opening provided in the top wall part, and includes a pouring nozzle protruding outward from the opening. The pouring nozzle is formed of an elastic material. When the lid part is closed, the pouring nozzle is stored below the lid part in a deformed state pressed by the lid part. When the lid part is open, the pouring nozzle is restored by elasticity and protrudes outward from the opening.

Advantages of the Invention

[0007] According to the present invention, the contents can be poured out to a desired place, and a compact cap can be provided.

On the lower surface of the bridge portion 15, a groove portion 15c (FIG. 1) extending along the first edge portion 15a is provided.

[0014] In a plan view, the top wall portion 14 is divided into a first region 16a and a second region 16b having an area smaller than that of the first region 16a with the bridge portion 15 as a boundary. Specifically, the first region 16a is a substantially semicircular portion outside the first edge portion 15a in a plan view. The second region 16b is a substantially semicircular portion outside the second edge portion 15b in a plan view.

[0015] In the first region 16a, a first opening 17 (opening) defined by a portion of the cylindrical portion 13 facing the first edge portion 15a and the first edge portion 15a is provided. The first opening 17 is an opening in a substantially semi-circular shape in plan view.

[0016] In the second region 16b, a partition wall portion 18 closing the space between a portion of the cylindrical portion 13 facing the second edge portion 15b and the second edge portion 15b, and a second opening 19 passing through the partition wall portion 18 are provided.

[0017] The top wall portion 14 includes a first lid portion 21 (lid portion) that covers the first opening 17 in an openable and closable manner, and a second lid portion 22 that covers the second opening 19 and the partition wall portion 18 in an openable and closable manner. In FIG. 4, the first lid portion 21 and the second lid portion 22 are shown in a state of being opened halfway.

[0018] The first lid portion 21 is formed in a substantially semi-circular shape in accordance with the shape of the first region 16a. The first lid portion 21 is opened and closed by rotating about a first hinge portion 21a (hinge portion) provided on the first edge portion 15a. The first hinge portion 21a is linear along the first edge portion 15a, and is formed by partially thinning the plate thickness of the base end portion of the first lid portion 21.

[0019] The first lid portion 21 includes a semi-circular first lid plate portion 21b that covers the first opening 17, a peripheral wall portion 21c that extends downward from the periphery of the first lid plate portion 21b, and a first lock portion 21d that protrudes from the inner surface of the peripheral wall portion 21c. The first lock portion 21d is provided at the tip end portion of the first lid portion 21 located on the side opposite to the first hinge portion 21a. The first lid portion 21 is locked in a closed state when the first lock portion 21d engages with an engaging portion 13c provided on the outer periphery of the upper end portion of the cylindrical portion 13. Further, the first lid portion 21 is provided with a pair of protrusions 21e (FIGS. 1 and 4) that extend downward from the lower surface of the first lid plate portion 21b at the base end portion of the first lid portion 21.

[0020] The second lid portion 22 is formed in a substantially semi-circular shape in accordance with the shape of the second region 16b. The second lid portion 22 is opened and closed by rotating about a second hinge portion 22a provided at the second edge portion 15b. The second hinge portion 22a is linear along the second edge portion 15b and is formed by partially thinning the plate thickness of the base end portion of the second lid portion 22.

[0021] The second lid portion 22 includes a semi-circular second lid plate portion 22b that covers the second opening 19 and the partition wall portion 18, a peripheral wall portion 22c that extends downward from the periphery of the second lid plate portion 22b, and a second locking portion 22d that protrudes from the inner surface of the peripheral wall portion 22c. The second lid portion 22 is locked in a closed state when the second locking portion 22d engages with an engaging portion 13d provided on the outer periphery of the upper end portion of the cylindrical portion 13.

[0022] FIG. 5A is a plan view of the middle lid 12 as viewed from above. FIG. 5B is a front view of the middle lid 12. Referring to FIGS. 1 to 5, the middle lid 12 includes a disk-shaped base portion 30 in plan view, an annular middle lid peripheral wall portion 31 that extends downward from the periphery of the base portion 30, a pouring nozzle 32 that protrudes upward from the base portion 30, a pair of convex portions 33 that protrude upward from the base portion 30 on the side of the pouring nozzle 32, a pedestal portion 34 that protrudes upward from the base portion 30, and a rib 35 that protrudes upward from the base portion 30 between the pedestal portion 34 and the pouring nozzle 32. The rib 35 extends linearly so as to partition between the pedestal portion 34 and the pouring nozzle 32.

[0023] In the middle lid 12, the base portion 30, the middle lid peripheral wall portion 31, the pouring nozzle 32, the convex portions 33, the pedestal portion 34, and the rib 35 are integrally formed of an elastic material and are relatively easily deformed by an external force. This elastic material is, for example, an elastomer. The middle lid 12 is formed of a softer material than the cap body 11. The cap body 11 is made of, for example, synthetic resin.

[0024] The middle lid 12 is mounted inside the cap body 11 by fitting the middle lid peripheral wall portion 31 into the middle lid storage portion 13b of the cylindrical portion 13. Further, the middle lid 12 is fixed in the vertical direction by being sandwiched between the lower surface of the top wall portion 14 and the upper end of the mouth portion 2a. Furthermore, the middle lid 12 is prevented from rotating about the axis 2d by engaging the rib 35 with the groove portion 15c on the lower surface of the bridge portion 15.

[0025] The pouring nozzle 32 and the convex portion 33 are arranged in the first region 16a and protrude upward from the first opening 17 of the top wall portion 14 when the first lid portion 21 is open. Specifically, the pouring nozzle 32 extends from the base portion 30 and obliquely protrudes forward and upward through the first opening 17. In the following description, the direction in which the pouring nozzle 32 protrudes in plan view is defined as the front direction F, the opposite direction is defined as the rear direction, and the left - right direction is defined based on this front - rear direction for explanation. The bridge portion 15 extends linearly in the left - right direction.

[0026] The pouring nozzle 32 is arranged at the left - right center portion of the cap body 11. The pouring nozzle 32 includes a rear wall portion 41 that extends obliquely forward and upward from a position slightly in front of the first hinge portion 21a, a front wall portion 42 that faces the rear wall portion 41, and a pair of left - right side wall portions 43 that connect the rear wall portion 41 and the front wall portion 42 front - to - back, and is formed in a cylindrical shape. The opening provided at the tip of the cylindrical pouring nozzle 32 is a pouring outlet 44 for pouring the content to the outside. The pouring outlet 44 opens forward and upward.

[0027] The lower end 42a of the front wall portion 42 is located on the upper surface of the front end portion of the base portion 30. The front wall portion 42 includes a lower side wall portion 42b that extends obliquely rearward and upward from the lower end 42a toward the rear wall portion 41, and an upper side wall portion 42c that extends from the upper end of the lower side wall portion 42b along the rear wall portion 41 to the front - upward pouring outlet 44. The front wall portion 42 is bent at the boundary portion 42d between the lower side wall portion 42b and the upper side wall portion 42c, and the upper side wall portion 42c is bent approximately 80° forward with respect to the lower side wall portion 42b. Note that the front wall portion 42 may be bent approximately 90°, or may be bent 90° or more. The inner diameter of the pouring nozzle 32 is formed in a tapered shape such that the lower part is large and becomes smaller as it goes upward due to the inclination of the rear wall portion 41 and the lower side wall portion 42b. The distance between the left and right side wall portions 43 becomes smaller as it goes upward. Also, the upper part of the rear wall portion 41 and the upper side wall portion 42c are substantially parallel.

[0028] FIG. 6 is a cross-sectional view taken along line B-B of FIG. 3, showing the state where the first lid portion 21 is opened. Referring to FIGS. 1 to 6, the convex portions 33 are respectively arranged on the left and right sides of the pouring nozzle 32. In the front-rear direction, the convex portions 33 are arranged between the pouring port 44 and the first hinge portion 21a. Also, the convex portions 33 are arranged behind the front wall portion 42. The convex portion 33 is arranged in front of the protrusion 21e such that the protrusion 21e contacts the convex portion 33 from the rear upper side when the first lid portion 21 is closed. A pair of left and right concave portions 36 that are recessed downward are provided in the base portion 30, and a part of the convex portion 33 stands upright upward from the concave portion 36. In plan view, the front-rear length of the concave portion 36 is larger than the front-rear length of the convex portion 33, and the left-right length of the concave portion 36 is larger than the left-right length of the convex portion 33.

[0029] Specifically, the front wall 33a of the convex portion 33 stands upright upward from the front edge of the upper surface portion of the concave portion 36, and the outer side walls 33b in the left-right direction of the convex portion 33 stand upright upward from the outer side edges in the left-right direction of the upper surface portion of the concave portion 36. Also, the rear wall 33c (side surface) of the convex portion 33 and the inner side walls 33d in the left-right direction of the convex portion 33 stand upright upward from the bottom surface 36a of the concave portion 36. The upper surface 33e of the convex portion 33 is located below the upper end of the pouring nozzle 32.

[0030] The base portion 34 of the middle lid 12 is fitted into the second opening 19 of the top wall portion 14 from below and protrudes upward from the second opening 19. A plurality of pouring openings 34a penetrating the base portion 34 are formed in the base portion 34. A second pouring port 45 for pouring the contents to the outside is formed by the collection of the plurality of pouring openings 34a. The second discharge port 45 is blocked from above by the second lid portion 22 when the second lid portion 22 is closed.

[0031] FIG. 7 is a cross-sectional view taken along line B-B of FIG. 3, showing the state where the first lid portion 21 is closed. FIG. 8 is a cross-sectional view taken along line A-A of FIG. 3, showing an intermediate state when the first lid portion 21 is being opened. In FIG. 8, the convex portion 33 is shown by a phantom line in a non-deformed state. Here, the operations of the discharge nozzle 32 and the convex portion 33 accompanying the opening and closing of the first lid portion 21 will be described.

[0032] As shown in FIG. 2, when the first lid portion 21 is closed, the discharge nozzle 32 is elastically deformed by being pressed by the first lid portion 21 and is stored below the first lid portion 21. Specifically, the rear wall portion 41 of the discharge nozzle 32 is pushed downward by the lower surface of the first lid plate portion 21b and is deformed so as to fall toward the side opposite to the first hinge portion 21a (front side). Also, the lower side wall portion 42b of the front wall portion 42 is deformed so as to fall toward the first hinge portion 21a side with the lower end 42a as a starting point. Further, the upper side wall portion 42c of the front wall portion 42 is deformed so as to fall toward the side opposite to the first hinge portion 21a with the boundary portion 42d as a starting point and is bent into a substantially U shape and abuts on the upper surface of the lower side wall portion 42b. In this state, the inner surface of the boundary portion 42d abuts on the inner surface of the rear wall portion 41, closing the passage inside the discharge nozzle 32. The first lid portion 21 is locked in the closed state by the first locking portion 21d engaging with the engaging portion 13c.

[0033] In this way, when the first lid portion 21 is closed, the discharge nozzle 32 is pushed by the first lid plate portion 21b, deformed, and stored, so that the cap 10 becomes compact. Also, when the first lid portion 21 is closed, the boundary portion 42d abuts on the rear wall portion 41 and the passage inside the discharge nozzle 32 is closed, so that the airtightness of the cap 10 can be improved.

[0034] As shown in FIG. 7, when the first lid portion 21 is in the closed state, the convex portion 33 of the middle lid 12 is stored below the first lid portion 21 while being elastically deformed by being pressed by the first lid portion 21. Specifically, the convex portion 33 is deformed so as to fall to the side opposite to the first hinge portion 21 (front side) by the lower portion of the rear wall 33c being pushed downward by the lower end portion of the protrusion 21e and the upper surface 33e being pushed downward by the lower surface of the first lid plate portion 21b. In this state, the lower portion of the protrusion 21e is located within the concave portion 36, and the front surface portion of the lower end portion of the protrusion 21e is in contact with the rear wall 33c.

[0035] When the user pushes up the tip of the first lid portion 21, the engagement between the first lock portion 21d and the engagement portion 13c is released, and the first lid portion 21 can be opened. When the engagement of the first lock portion 21d is released, the elastically deformed pouring nozzle 32 returns to its original shape as shown in FIGS. 8 and 1, and the first lid portion 21 is pushed upward by the returning pouring nozzle 32 and automatically opened.

[0036] Referring to FIGS. 7, 8, and 6, when the first lid portion 21 is opened about the first hinge portion 21a, the protrusion 21e rotates upward while in contact with the rear wall 33c of the convex portion 33 and moves while generating friction between the protrusion 21e and the rear wall 33c of the convex portion 33. Due to the resistance of this friction, the speed at which the first lid portion 21 opens is decelerated, so that the pouring nozzle 32 is prevented from restoring with excessive force.

[0037] The first lid portion 21 is automatically opened by the restoring force of the pouring nozzle 32 and the restoring force of the convex portion 33 up to, for example, the opening degree shown in FIG. 8. Thereafter, when the user pushes the first lid portion 21 to open it further as shown in FIG. 6, the upper surface 33e of the convex portion 33 comes into contact with the rear surface portion 21f of the protrusion 21e from below, and the convex portion 33 supports the first lid portion 21 so that the first lid portion 21 is in the fully opened state. As shown in FIG. 6, in the state where the first lid portion 21 is fully opened, the first lid portion 21 is opened by 90° or more with respect to the horizontal upper surface of the top wall portion 14.

[0038] When the user dispenses the contents from the dispensing nozzle 32, as shown in FIG. 1, the user holds the dispensing container 1 with the first lid portion 21 open, directs the dispensing nozzle 32 toward a desired location (e.g., a measuring spoon), and tilts the dispensing container 1 so that the discharge port 44 faces downward, and dispenses the contents from the discharge port 44 to the desired location. For example, when the dispensing container 1 is tilted so that the axis 2d is substantially horizontal, the discharge port 44 opens obliquely downward, so that the contents can be dispensed downward. In this case, since the first lid portion 21 opens by 90° or more with respect to the top wall portion 14, the first lid portion 21 does not interfere, and the dispensing nozzle 32 can be visually recognized from the lateral direction, and it is easy to direct the dispensing nozzle 32 to a desired location. In this way, by discharging the contents by the dispensing nozzle 32 protruding upward with respect to the top wall portion 14, it becomes easier to discharge the contents aiming at a desired location. Further, since the dispensing nozzle 32 extends obliquely forward and upward, the angle at which the dispensing container 1 is tilted when discharging can be reduced, and since the user can easily visually recognize the dispensing nozzle 32, the contents can be easily discharged to a desired location.

[0039] When storing the dispensing nozzle 32 and the convex portion 33, they can be stored by closing the first lid portion 21. Specifically, when closing the first lid portion 21 around the first hinge portion 21a, the first lid portion 21 abuts against the dispensing nozzle 32 inclined to the opposite side (front side) with respect to the first hinge portion 21a, and deforms downward so as to tilt the dispensing nozzle 32 forward. In this way, since the dispensing nozzle 32 inclined forward is tilted forward by the first lid portion 21, the dispensing nozzle 32 can be easily stored. Further, when closing the first lid portion 21 around the first hinge portion 21a, the protrusion 21e of the first lid portion 21 abuts against the convex portion 33 from the rear, and deforms downward so as to tilt the convex portion 33 forward.

[0040] Also, in a state where the second lid portion 22 is open (not shown), the contents can be discharged from the second discharge port 45. As shown in FIG. 3, the left - right width W1 of the discharge port 44 of the discharge nozzle 32 is smaller than the left - right width W2 of the second discharge port 45. Therefore, by using the discharge nozzle 32, the content can be discharged in a range narrower than the second discharge port 45, and it is easy to discharge the content to a desired location. On the other hand, by using the second discharge port 45, the content can be discharged over a wide range. Here, the width W2 of the second discharge port 45 is the maximum width in the left - right direction of the second discharge port 45, and is the width between the outer end of the right - most discharge opening 34a and the outer end of the left - most discharge opening 34a among the plurality of discharge openings 34a.

[0041] As described above, according to the embodiment to which the present invention is applied, the cap 10 includes a cylindrical portion 13 attached to the mouth portion 2a of the container body 2 for storing the content, a top wall portion 14 that closes the mouth opening 2e on the upper surface of the mouth portion 2a, and a first lid portion 21 that openably and closably covers the first opening 17 provided in the top wall portion 14. The cap 10 includes a discharge nozzle 32 that protrudes outward from the first opening 17. The discharge nozzle 32 is formed of an elastic material. In a state where the first lid portion 21 is closed, the discharge nozzle 32 is pushed by the first lid portion 21 and deformed, and is stored below the first lid portion 21. In a state where the first lid portion 21 is open, the discharge nozzle 32 is restored by elasticity and protrudes outward from the first opening 17. According to this configuration, in a state where the first lid portion 21 is open, the discharge nozzle 32 protrudes outward from the first opening 17 of the top wall portion 14 of the cap 10, and the content can be discharged from the discharge nozzle 32. Therefore, the content can be discharged aiming at a desired location by aiming the discharge nozzle 32 at the desired location. For this reason, the content can be discharged to a desired location. Also, in a state where the first lid portion 21 is closed, since the discharge nozzle 32 is deformed and stored below the first lid portion 21, the cap 10 can be made compact.

[0042] Further, the first lid portion 21 is openable and closable about a first hinge portion 21a provided on the top wall portion 14, and the discharge nozzle 32 extends obliquely upward from the first opening 17 upward and in a direction opposite to the first hinge portion 21a. According to this configuration, when closing the first lid portion 21 around the first hinge portion 21a, the pouring nozzle 32 in an inclined state on the side opposite to the first hinge portion 21a can be pushed by the first lid portion 21. Therefore, the pouring nozzle 32 can be easily deformed by the first lid portion 21, and the pouring nozzle 32 can be easily stored below the first lid portion 21. Further, since the pouring nozzle 32 extends obliquely upward on the side opposite to the first hinge portion 21a, the first lid portion 21 is less likely to interfere with the pouring nozzle 32, and it is easy to pour out from the pouring nozzle 32.

[0043] Also, a convex portion 33 protruding upward from the first opening 17 is provided. The convex portion 33 is formed of an elastic material. The first lid portion 21 includes a protrusion 21e protruding toward the first opening 17. In a state where the first lid portion 21 is closed, the protrusion 21e abuts against the convex portion 33 to deform the convex portion 33, and the first lid portion 21 is opened while generating friction between the protrusion 21e and the rear wall 33c of the convex portion 33. According to this configuration, since the first lid portion 21 is opened while generating friction between the protrusion 21e and the rear wall 33c of the convex portion 33, the first lid portion 21 can be slowly opened. Thereby, it is possible to suppress the pouring nozzle 32 from restoring with excessive momentum, and it is possible to suppress the scattering of the content from the pouring nozzle 32 when the pouring nozzle 32 is restored.

[0044] Furthermore, in a state where the first lid portion 21 is opened to the maximum, the convex portion 33 supports the protrusion 21e from below, so that the first lid portion 21 is opened by 90° or more with respect to the top wall portion 14. According to this configuration, the convex portion 33 can be used to maintain the first lid portion 21 in a largely opened state. When the first lid portion 21 is opened by 90° or more with respect to the top wall portion 14, the first lid portion 21 is less likely to interfere with the pouring nozzle 32, and it is easy to pour out the content from the pouring nozzle 32.

[0045] Also, an inner lid 12 that closes the first opening 17 is provided below the top wall portion 14. The inner lid 12 is formed of an elastic material, and the pouring nozzle 32 and the convex portion 33 are integrally provided on the inner lid 12. According to this configuration, the sealing performance of the cap 10 can be improved by the inner lid 12 made of an elastic material, and the pouring nozzle 32 and the convex portion 33 formed of the elastic material can be provided with a simple structure using the inner lid 12.

[0046] Further, the pouring nozzle 32 includes a rear wall portion 41 pressed by the first lid portion 21, a front wall portion 42 facing the rear wall portion 41, and a pair of side wall portions 43 connecting the rear wall portion 41 and the front wall portion 42, and is formed in a cylindrical shape. The tip of the pouring nozzle 32 is open, and the rear wall portion 41 extends obliquely upward above and on the side opposite to the first hinge portion 21a. The front wall portion 42 includes a lower side wall portion 42b extending obliquely upward from the lower end 42a of the front wall portion 42 toward the rear wall portion 41, and an upper side wall portion 42c extending from the upper end of the lower side wall portion 42b along the rear wall portion 41 to the tip. In a state where the pouring nozzle 32 is housed below the first lid portion 21, a boundary portion 42d between the lower side wall portion 42b and the upper side wall portion 42c is bent by the first lid portion 21. According to this configuration, in a state where the pouring nozzle 32 is housed below the first lid portion 21, since the boundary portion 42d between the lower side wall portion 42b and the upper side wall portion 42c of the pouring nozzle 32 is bent, in a state where the pouring nozzle 32 is housed, the front wall portion 42 and the rear wall portion 41 can be easily brought into contact with each other, and the sealing performance of the pouring nozzle 32 in a state where the pouring nozzle 32 is housed can be improved. Further, in the portion of the lower side wall portion 42b, the distance between the rear wall portion 41 and the front wall portion 42 becomes large, and since the inner diameter of the pouring nozzle 32 can be ensured to be large, the content can be smoothly poured out from the pouring nozzle 32.

[0047] Further, a second pouring port 45 opened and closed by the second lid portion 22 is provided, and the width W1 of the pouring port 44 of the pouring nozzle 32 is smaller than the width W2 of the second pouring port 45. According to this configuration, the content can be poured out over a wide range using the second pouring port 45, and the content can be poured out to a desired location with a relatively narrow width using the pouring nozzle 32.

[0048] Furthermore, a first locking portion 21d for locking the first lid portion 21 in a closed state is provided. When the locking by the first locking portion 21d is released, the first lid portion 21 is pushed open by the restoring pouring nozzle 32. According to this configuration, the first locking portion 21d can maintain the state in which the pouring nozzle 32 is stored. Further, by releasing the first locking portion 21d, the first lid portion 21 can be automatically opened by the restoring force of the pouring nozzle 32.

[0049] As described above, an embodiment of the present invention has been described. However, the present invention is not limited to such a specific embodiment, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims, unless otherwise particularly limited in the above description. For example, the configuration of the above-described embodiment can be appropriately added or deleted, and the configuration of one embodiment can also be provided in another embodiment. Further, the effects in the above embodiments are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above effects. In the above embodiment, after the first lid portion 21 is automatically opened by the restoring force of the pouring nozzle 32 and the restoring force of the convex portion 33, when the user presses the first lid portion 21 to further open the first lid portion 21, it has been described that the convex portion 33 abuts against the protrusion 21e and supports the first lid portion 21. However, the present invention is not limited to this. For example, the first lid portion 21 may be opened to a state where it is fully opened by the restoring force of the convex portion 33 and supported from below by the convex portion 33 in this state.
