Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The drawings show a schematic structure of the container lid according to each embodiment. Hereinafter, a bottle container such as a PET bottle will be described as an example of a container to which a container cap is attached.

[ first embodiment ]

Fig. 1 is a diagram showing an example of a container lid 1 of a first embodiment, in which fig. 1(a) shows a top surface, fig. 1(B) shows a front surface, fig. 1(C) shows a bottom surface, and fig. 1(D) shows a side surface. Fig. 2 is a sectional view showing one example of the internal structure of the container lid 1, in which fig. 2(a) shows a state in which the discharge port 24 is closed, and fig. 2(B) shows a state in which the discharge port 24 is opened. Fig. 3 is a sectional perspective view showing one example of the internal structure of the container lid 1, in which fig. 3(a) shows a state in which the discharge port 24 is closed, and fig. 3(B) shows a state in which the discharge port 24 is opened. Fig. 2 and 3 show a cross section a-a of fig. 1 (a).

The container lid 1 includes a body 10, a storage 20, and a pair of levers 30. As a material of the container lid 1, for example, a resin such as polyethylene or polypropylene having flexibility or elasticity can be used.

The body 10 is formed in a cylindrical shape with its top surface closed. An internal thread 15 is formed on the inner side surface of the body portion 10, and the internal thread 15 is screwed with an external thread formed on the outer periphery of the mouth portion (not shown) of the container.

The housing 20 is formed in a cylindrical shape and is provided in the center of the upper wall 11 so as to penetrate the upper wall 11 of the body 10. That is, the upper portion of the housing 20 protrudes from the top surface of the main body 10, and the lower portion of the housing 20 is disposed inside the main body 10. The top surface of the storage section 20 can be opened and closed by a detachable cover 21. The top surface of the storage unit 20 may be closed so as not to be openable and closable. The interior of the housing 20 is divided into two symmetrical chambers 23 by a partition wall 22. A pair of discharge ports 24 communicating with the chambers 23 are formed in the bottom of the housing portion 20.

The pair of operation levers 30 are formed in a rod shape, and are provided on the upper side wall 11 of the main body 10 so as to penetrate the upper side wall 11 and outside the housing section 20. The left and right levers 30 are in line symmetry with respect to the main body 10.

The upper end of the operating lever 30 extends above the main body 10 and can be pressed by a user's finger from the outside of the main body 10.

The center portion of the operating lever 30 is supported on the upper side wall 11 of the main body 10. The center portion of the operating lever 30 is connected to the upper side wall 11 so that the operating lever 30 can rotate about the axis P in the depth direction shown in fig. 2. The connecting method of the central portion of the operating lever 30 and the upper side wall 11 is not limited, and for example, the connecting method may be a method of connecting the central portion of the operating lever 30 and the upper side wall 11 by a bearing and a rotating shaft, or a method of connecting the central portion of the operating lever 30 and the upper side wall 11 by forming a connecting portion thinner than the periphery thereof. With this structure, the operation lever 30 can be operated so that the lower end portion thereof approaches or separates from the bottom portion of the housing portion 20.

The lower end of the operating lever 30 extends into the main body 10 and extends to the vicinity of the discharge port 24. The lower end portion of the operation lever 30 is disposed such that the inner side surface thereof and the discharge port 24 face each other. A projection 31 inserted into the discharge port 24 for fitting is formed on the inner side surface thereof.

Further, an abutment portion 32 protruding in the outward direction is formed on the outer side of the lower end portion of the operating lever 30. As will be described in detail below, the abutment 32 has the function of: the lower end of the operating lever 30 is restricted from moving in the outward direction by abutting against the inner surface of the mouth of the container.

Here, the operation lever 30 is supported by the upper side wall 11 so as to be biased in the closing direction with the closed state (the state in which the convex portion 31 is fitted to the discharge port 24) as the initial posture by, for example, integral molding of resin.

A cylindrical inner peripheral wall 18 is vertically provided on the bottom surface of the upper side wall 11 so as to surround the housing portion 20 and the pair of operation levers 30. The outer diameter of the inner peripheral wall 18 is configured to be equal to or slightly smaller than the inner diameter of the mouth portion of the container. The inner peripheral wall 18 is inserted into the mouth portion of the container in a state where the container lid 1 is fastened to the mouth portion of the container. This prevents the additive (liquid, etc.) in the container B from leaking out. Further, the abutting portion 32 is located below the inner circumferential wall 18.

In the state of fig. 2(a) and 3(a), projection 31 is fitted to discharge port 24. In this state, the user pinches the upper end portions of the pair of operation levers 30 from the outside and presses them in the inward direction. Thus, as shown in fig. 3(a) and 3(B), the lower end portion of each operating lever 30 is moved in the outward direction by being rotated about the axis P. This releases the fitting of projection 31 to discharge port 24, and discharge port 24 is opened.

Next, the operation of the container lid 1 will be described in chronological order in the process of removing the container lid 1 from the container.

Fig. 4 is a sectional view illustrating an example of the operation of the container cover 1, in which fig. 4(a) shows a state in which the container cover 1 is fastened and the discharge port 24 is closed, fig. 4(B) shows a state in which the container cover 1 is loosened, and fig. 4(C) shows a state in which the container cover 1 is further loosened and the discharge port 24 is opened. Fig. 4 shows a cross section of fig. 1(a) taken along a-a. Further, fig. 4 shows a cross section of the mouth portion of the container B (hatching is omitted).

Fig. 4 (a): first, the container lid 1 is fastened to the mouth of the container B. In the present embodiment, the dimension between the outer ends of the pair of contact portions 32 is configured to match the inner diameter of the mouth portion of the container B in a state where the corresponding discharge port 24 is closed by the pair of levers 30. Therefore, in the state of fig. 4(a), the outer end portions of the pair of abutting portions 32 abut against the inner side surface of the mouth portion of the container B, and even if the user pinches the upper end portions of the pair of operation levers 30 from the outside and presses them in the inward direction, the operation levers 30 cannot be moved. In this state, the discharge port 24 is closed, and thus the additive (e.g., a liquid, a dot-hatched portion in the figure) is prevented from being discharged from the housing portion 20.

Fig. 4 (B): next, when the user pinches the body portion 10 to rotate it leftward and starts to loosen it, the abutting portion 32 is also raised along with the rise of the container lid 1 (hollow arrow in the figure). Until the outer end of the abutting portion 32 exceeds the upper end surface of the mouth portion of the container B, the outer end surface of the abutting portion 32 abuts against the inner peripheral surface of the mouth portion, and the abutting portion 32 is held in abutment against the inner peripheral surface of the mouth portion.

Fig. 4 (C): thereafter, the container lid 1 is further raised, and the outer end of the abutting portion 32 is moved beyond the upper end surface of the mouth portion of the container B, thereby releasing the abutting. In this state, when the user pinches the upper end portions of the pair of operation levers 30 from the outside and presses them in the inward direction, the front end portions of the operation levers 30 move in the outward direction and the discharge port 24 is opened. When the discharge port 24 is opened, the additive is discharged from the chamber 23 of the container 20 into the container B through the discharge port 24. When the user releases the operating lever 30 with his or her finger, the operating lever 30 returns to the above-described initial posture by its restoring force, and the discharge port 24 is closed. Alternatively, the user may press only one of the operation levers 30. In this case, the additive is discharged from one chamber 23.

The first embodiment of the present invention has been described above. According to the container lid 1 of the present embodiment, a user can select whether or not an additive is added to the container. Furthermore, the user may also choose to add an additive to only one 23 of the two compartments 23. Further, the user may close the discharge port and stop the addition of the additive by releasing the lever.

[ second embodiment ]

The container lid 1A of the second embodiment is different from the first embodiment in the internal structure of the body portion 10. Hereinafter, the same components as those of the first embodiment among the components of the second embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

Fig. 5 is a diagram showing an example of a container lid 1A of the second embodiment, in which fig. 5(a) shows a top surface, fig. 5(B) shows a front surface, fig. 5(C) shows a bottom surface, and fig. 5(D) shows a side surface. Fig. 6 is a sectional view showing one example of the internal structure of the container lid 1A, in which fig. 6(a) shows a state where the door portion 25A is closed, and fig. 6(B) shows a state where the door portion 25A is opened. Fig. 7 is a sectional perspective view showing one example of the internal structure of the container lid 1A, in which fig. 7(a) shows a state in which the door portion 25A is closed, and fig. 7(B) shows a state in which the door portion 25A is opened. Fig. 6 and 7 show a cross section taken along B-B of fig. 5 (a).

The container cover 1A has a storage portion 20A and an operation lever 30A which are partially different from the storage portion 20 and the operation lever 30 of the first embodiment.

A pair of gate portions 25A corresponding to the pair of discharge ports 24A communicating with the chambers 23 are provided at the bottom of the housing portion 20A. The door 25A is pivotally supported at the center of the bottom so as to be capable of opening and closing the discharge port 24A.

The lower end of the operating lever 30A has an engaging portion 33A formed on the inner side surface thereof to be engaged with the bottom surface of the door portion 25A.

Here, the door portion 25A is formed in an initial posture in an open state (for example, a state in which the front end portion of the door portion 25A is vertically oriented downward) by, for example, integral molding of resin, and in a closed state, the shaft thereof is deflected and biased in the opening direction. Therefore, in the closed state, the bottom surface of the door portion 25A is locked by the locking portion 33A and cannot move in the opening direction.

In the state of fig. 6(a) and 7(a), the locking portion 33A locks the door portion 25A. In this state, the user pinches the upper end portions of the pair of operation levers 30A from the outside and presses them in the inward direction. As shown in fig. 6(B) and 7(B), the lower end of each operating lever 30A is moved in the outward direction by rotating about the axis P. Thus, the locking of the door 25A by the locking portion 33A is released, the door 25A is opened, and the discharge port 24A is opened.

Next, the operation of the container lid 1A will be described in chronological order in the process of removing the container lid 1A from the container.

Fig. 8 is a sectional view illustrating an example of the operation of the container cover 1A, in which fig. 8(a) shows a state in which the container cover 1A is fastened and the door portion 25A is closed, fig. 8(B) shows a state in which the container cover 1A is loosened, and fig. 8(C) shows a state in which the container cover 1A is further loosened and the door portion 25A is opened. Fig. 8 shows a cross section taken along a-a of fig. 5 (a). Further, fig. 8 shows a cross section of the mouth of the container B.

Fig. 8 (a): first, the container lid 1A is fastened to the mouth of the container B. In the present embodiment, in a state where the corresponding gate portion 25A is locked by the pair of levers 30A (a state where the discharge port 24A is closed), the dimension between the outer end portions of the pair of abutment portions 32 is configured to match the inner diameter of the mouth portion of the container. Therefore, in the state of fig. 8(a), the outer end portions of the pair of abutting portions 32 abut against the inner side surface of the mouth portion of the container B, and even if the user pinches the upper end portions of the pair of operation levers 30A from the outside and presses them in the inward direction, the operation levers 30A cannot be moved. In this state, the discharge port 24 is closed, and thus the additive (e.g., liquid) is prevented from being discharged from the storage portion 20A.

Fig. 8 (B): next, when the user pinches the body portion 10 and turns it leftward to start loosening, the abutting portion 32 rises along with the rise of the container lid 1A (hollow arrow in the figure). Before the outer end of the abutting portion 32 exceeds the upper end surface of the mouth portion of the container, the outer end surface of the abutting portion 32 abuts against the inner peripheral surface of the mouth portion, and the abutting portion 32 is held in abutment against the inner peripheral surface of the mouth portion.

Fig. 8 (C): thereafter, the container lid 1A is further raised, and the outer end of the abutting portion 32 is moved beyond the upper end surface of the mouth portion of the container, thereby releasing the abutting. In this state, when the user pinches the upper ends of the pair of operation levers 30A from the outside and presses them in the inward direction, the front ends of the operation levers 30A move in the outward direction and release the locking of the door 25A, the door 25A opens, and the discharge port 24A opens. When the discharge port 24A is opened, the additive is discharged from the chamber 23 of the container 20A. Alternatively, the user may press only one of the operation levers 30A. In this case, the additive is discharged from one chamber 23.

The second embodiment of the present invention has been described above. According to the container lid 1A of the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, even if the user releases the lever, the discharge port is not closed and the addition of the additive is not stopped.

[ third embodiment ]

The container lid 1B of the third embodiment is used in a set with the auxiliary lid 4 as an accessory member. Hereinafter, the same components as those of the first embodiment among the components of the third embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

Fig. 9 is a diagram showing an example of a container lid 1B of the third embodiment. Fig. 9 shows the front surface of the container cover 1B.

A male screw 12B is formed on the outer peripheral surface of the body portion 10 of the container lid 1B, and the male screw 12B is screwed to a female screw 41 formed on the inner peripheral surface of an auxiliary lid 4 described later. The other portions are the same as those of the first embodiment.

Fig. 10 is a diagram showing one embodiment of the auxiliary lid 4, in which fig. 10(a) shows a top surface, fig. 10(B) shows a front surface, fig. 10(C) shows a bottom surface, and fig. 10(D) shows a cross section taken along C-C of fig. 10 (a).

The main body portion 40 of the auxiliary lid 4 is formed in a cylindrical shape. A female screw 41 is formed on the lower side of the inner surface of the body 40, and the female screw 41 is screwed to the male screw 12B of the container lid 1B. A pair of projections 42 are formed on the upper side of the inner surface of the body 40. In the example of fig. 10, the convex portion 42 is formed in a curved surface shape gradually bulging from the inner peripheral surface.

In the present embodiment, the pair of protrusions 42 are disposed on the inner peripheral surface of the body portion 40 so as to face the outer side surfaces of the upper end portions of the pair of operation levers 30 in a state where the auxiliary lid 4 is fastened to the container lid 1B. That is, in a state where the auxiliary lid 4 is loosened, the pair of protrusions 42 do not face the outer side surfaces of the upper end portions of the pair of operation levers 30.

Next, the operations of the auxiliary lid 4 and the container lid 1B will be described in chronological order from the mounting of the auxiliary lid 4 to the container lid 1B to the removal of the container lid 1B from the container.

Fig. 11 is a view for explaining an example of the operation of the container cover 1B and the auxiliary lid 4, in which fig. 11(a) shows a state where the auxiliary lid 4 is relaxed, and fig. 11(B) shows a state where the auxiliary lid 4 is fastened to the bottom. Fig. 11 shows the top surfaces of the container lid 1B and the auxiliary lid 4. In addition, it is assumed that the container lid 1B is fastened to the mouth of the container B.

Fig. 11 (a): the auxiliary lid 4 is not fastened to the container lid 1B, but covers only the container lid 1B. In this state, the positions of the convex portion 42 and the upper end portion of the operation lever 30 do not coincide, and the upper end portion of the operation lever 30 is not pressed in the inward direction. When the user pinches the auxiliary lid 4 and rotates it to the right, the projection 42 is also lowered as the auxiliary lid 4 is lowered.

Fig. 11 (B): when the user fastens the auxiliary lid 4 to the container lid 1B to the bottom, the positions of the projection 42 and the upper end portion of the operation lever 30 coincide. In this state, the upper end portion of the operation lever 30 is pressed inward. Here, since the outer end of the abutment portion 32 abuts against the inner surface of the mouth portion of the container B, the portion of the operating lever 30 from the central portion to the upper end portion is bent and curved in the inward direction. A moment in the outboard direction is applied to the abutment 32.

Thereafter, when the user grips the container lid 1B together with the auxiliary lid 4 and turns it leftward to start loosening, the abutting portion 32 also rises with the rise of the container lid 1B. Until the outer end of the abutting portion 32 exceeds the upper end surface of the mouth portion of the container B, the outer end surface of the abutting portion 32 presses and abuts against the inner peripheral surface of the mouth portion, and the abutting of the abutting portion 32 against the inner peripheral surface of the mouth portion is maintained.

The container lid 1B is further raised, and the outer end of the abutting portion 32 is moved beyond the upper end surface of the mouth portion of the container B, thereby releasing the abutting. At this time, since a moment in the outside direction is applied to the lower end portions of the pair of operation levers 30 in fig. 11(B) described above, the distal end portions of the operation levers 30 move in the outside direction and the discharge port 24 is opened. When the discharge port 24 is opened, the additive is discharged from the chamber 23 of the receiving portion 20.

The third embodiment of the present invention has been described above. According to the container lid 1B and the auxiliary lid 4 of the present embodiment, the user can discharge the additive by simply rotating the lids.

In the third embodiment, the direction of the loosening auxiliary lid 4 and the direction of the loosening container lid 1B are aligned (both are turned left). However, the direction of loosening the auxiliary lid 4 may be opposite to the direction of loosening the container lid 1B. For example, the auxiliary lid 4 is configured to be fastened to the container lid 1B by turning left. In this way, the user can loosen the container lid 1B by fastening the auxiliary lid 4 to the container lid 1B by turning left and continuing to turn left the auxiliary lid 4.

Fig. 12 is a diagram illustrating a modification of the container lid 1B and the auxiliary lid 4 according to the third embodiment, in which fig. 12(a) shows a state in which the auxiliary lid 4 is loosened, and fig. 12(B) shows a state in which the auxiliary lid 4 is fastened to the bottom.

A first engaging portion 45 having a concave shape such as a groove or a hole is formed at the distal end of the convex portion 42. A second engagement portion 35 having a convex shape such as a projection is formed on the outer surface of the upper end portion of the operating lever 30. The first engaging portion 45 and the second engaging portion 35 are engaged with each other at a position where the convex portion 42 and the operation lever 30 face each other. Thus, the user can recognize the position where the operation lever 30 can be maximally pressed by visual or tactile senses, thereby stopping the rotation of the auxiliary lid 4. Of course, the first engaging portion 45 may be formed in a convex shape, and the second engaging portion 35 may be formed in a concave shape.

Fig. 13 is a diagram illustrating another modification of the container lid 1B and the auxiliary lid 4 according to the third embodiment, in which fig. 13(a) shows a cross section of the auxiliary lid 4C of the present modification, and fig. 13(B) shows a front surface of the container lid 1C of the present modification.

The container lid 1C has an annular projection 13 on the outer peripheral surface of the body 10 instead of the male screw 12B. The auxiliary lid 4C has an annular groove portion 43 on the inner peripheral surface of the body portion 40 instead of the female screw 41. The container lid 1C and the auxiliary lid 4C are attached to each other by the engagement structure of the convex portion 13 and the groove portion 43 so as to be rotatable with each other, instead of being screwed by a screw structure as in the third embodiment. In the case of this configuration, even if the auxiliary lid 4C is rotated, the lid does not move up and down with respect to the container lid 1C. Of course, a groove portion may be formed in the container lid 1C and a protrusion may be formed in the auxiliary lid 4C.

In the present modification, the auxiliary lid 4C may have one convex portion 42. Thus, the user can select either one of the two operation levers 30 to press.

Fig. 14 is a diagram illustrating a modification of the container lid 1C and the auxiliary lid 4C.

The auxiliary lid 4C has a first locking member 44 on its inner peripheral surface. The first locking member 44 is disposed above the groove portion 43 and at a position facing the convex portion 42. The first locking member 44 is configured such that the radial dimension of the auxiliary lid 4C is shorter than the projection 42 and does not contact the operation lever 30.

The container lid 1C has a pair of second locking members 14 on the top surface of the upper side wall 11. The pair of second locking members 14 are disposed near the respective operation levers 30 at the same height as the first locking members 44 of the auxiliary lid 4C attached to the container lid 1C. The container lid 1C is configured to: when the auxiliary lid 4C is rotated in one direction, one second locking member 14 and the first locking member 44 are brought into contact with each other, and when the auxiliary lid 4C is rotated in the opposite direction, the other second locking member 14 and the first locking member 44 are brought into contact with each other.

Fig. 15 is a diagram illustrating an example of the operation of the container cover 1C and the auxiliary cover 4C.

Fig. 15(a) shows a neutral state in which the convex portion 42 does not press any of the operation levers 30. In this state, the first locking member 44 is positioned between the pair of second locking members 14 within the range of the rotation angle.

Fig. 15(B) shows a state where the auxiliary lid 4C is turned by about 90 degrees to the left from the state of fig. 15 (a). When the auxiliary lid 4C is turned leftward, the first locking member 44 approaches the right second locking member 14, and the convex portion 42 approaches the left operating lever 30. Thereafter, the first locking member 44 abuts against the right second locking member 14, and the left rotation of the auxiliary lid 4C is restricted and stopped. At this time, the convex portion 42 is in a state of pressing the left operation lever 30.

When the right operation lever 30 is pressed from the state of fig. 15(B), the auxiliary lid 4C may be rotated rightward by about 180 degrees. The first locking member 44 abuts against the left second locking member 14, and restricts and stops the rightward rotation of the auxiliary lid 4C. At this time, the convex portion 42 is in a state of pressing the right operation lever 30.

The arrangement, shape, and number of the first locking member 44 and the second locking member 14 are not limited to the above configuration example, as long as the rotation of the auxiliary lid 4C can be restricted.

The features of the third embodiment and its modifications are not limited to those of the first embodiment, and can be applied to the second embodiment as well.

[ fourth embodiment ]

Fig. 16 is a diagram showing an example of the container lid 5 of the fourth embodiment, in which fig. 16(a) shows a top surface, fig. 16(B) shows a front surface, fig. 16(C) shows a bottom surface, and fig. 16(D) shows a side surface. Fig. 17 is a sectional view showing an example of the internal structure of the container lid 5, in which fig. 17(a) shows a state where the door portion 75 is closed, and fig. 17(B) shows a state where the door portion 75 is opened.

Fig. 18 is a sectional perspective view showing one example of the internal structure of the container lid 5, fig. 18(a) shows a state where the door portion 75 is closed, and fig. 18(B) shows a state where the door portion 75 is opened. Fig. 17 and 18 show a cross section taken along D-D of fig. 16 (a).

The container lid 5 has a main body portion 50 and a pair of operation levers 60.

The body portion 50 is formed in a cylindrical shape with a closed top surface. As will be described in detail later, a receiving portion 70 is formed at an inner upper portion of the outer peripheral wall 51 of the body portion 50, and an internal thread 55 is formed at an inner lower portion, the internal thread 55 being screw-coupled with an external thread formed on the outer periphery of the mouth portion of the container B.

The top surface of the main body portion 50 is constituted by a rising wall 52 and a connecting wall 53 (these may also be referred to as an upper side wall). The rising and falling wall 52 is disposed at the center of the top surface of the main body 50. The connecting wall 53 is formed in a ring shape to connect the rising and falling wall 52 to the inner peripheral surface of the outer peripheral wall 51. Here, the connecting wall 53 is formed thinner than the elevating wall 52, and supports the elevating wall 52 so as to be capable of elevating by its flexibility or elasticity.

A pair of operating levers 60 are provided on the top surface of the main body 50. The left and right levers 60 are in line-symmetric relation with the main body 50 as a center.

The operating lever 60 is composed of a plate-shaped first member 61 and a second member 62. The first member 61 is disposed outside the second member 62. The lower end portion of the first member 61 is connected to the top surface of the peripheral wall 51. On the other hand, the lower end portion of the second member 62 is connected to the top surface of the rising wall 52. Then, the upper end portion of the first member 61 and the upper end portion of the second member 62 are connected to each other in such a manner as to form a triangle above the main body portion 50. The operation lever 60 looks like a cat ear, for example, and the main body portion 50 looks like a cat face in the front view.

According to the configuration of the operating lever 60, when the upper end portion of the first member 61 moves toward the center of the body 50, the upper end portions of the first member 61 and the second member 62 can be pivoted about the lower end portion of the first member 61, and the lower end portion of the second member 62 can press down the rising wall 52 downward.

Here, the operation lever 60 is formed by, for example, integral molding of resin, and a state after moving to the inside (a state where the rising and lowering wall 52 is lowered, fig. 17(B)) is set as an initial posture. In the state of being opened outward (the state of the rising and lowering wall 52 rising, fig. 17(a)), the force is applied in the direction of moving inward.

The interior of the housing 70 is a single chamber. The bottom portion 71 of the housing portion 70 is formed of an annular flange portion 72 and a cylindrical tube portion 73 inside the flange portion 72.

The flange portion 72 extends obliquely downward from the inner surface of the outer peripheral wall 51 toward the center. The cylindrical portion 73 is connected to the inner end surface of the flange portion 72 and extends vertically downward. The outer diameter of the cylindrical portion 73 is configured to be equal to or slightly smaller than the inner diameter of the mouth portion of the container B. The cylindrical portion 73 is inserted into the mouth portion of the container B in a state where the container lid 5 is fastened to the mouth portion. This prevents the additive in the container B from leaking out.

A gate portion 75 (also referred to as a movable portion) corresponding to a discharge port communicating with the chamber of the housing portion 70 is provided at the bottom of the cylindrical portion 73. The door portion 75 is not connected to the bottom of the cylinder portion 73, but is connected to the elevating wall 52 (i.e., suspended from the elevating wall 52) by a rod portion 74 extending in the up-down direction.

Further, a pair of engaging portions 76 is provided on the top surface of the door portion 75. The engagement portion 76 is formed in a rod shape extending in the vertical direction, and a tip end portion thereof protrudes to the outside and is engaged with the top surface of the flange portion 72. As will be described in detail later, the click portion 76 has a function of restricting the lowering of the door portion 75.

According to the configuration of the housing portion 70 described above, when the elevating wall 52 moves downward, the door portion 75 also moves downward in association therewith.

Here, the connecting wall 53 is formed by, for example, integral molding, and the state in which the elevating wall 52 is lowered (the state in which the gate 75 is lowered and the discharge port is opened) is set as the initial posture. In the state where the rising and falling wall 52 is rising, the rising and falling wall 52 is biased in the direction of falling. In a state where the door portion 75 is closed, the engagement portion 76 is engaged with the top surface of the flange portion 72, and cannot be easily opened.

In the above description, both the operation lever 60 and the connection wall 53 have the restoring force to lower the rising and lowering wall 52, but only either one may have the restoring force.

In the present embodiment, the container B to which the container cover 5 is attached has a feature different from that of a general PET bottle.

Fig. 19 is a view showing a configuration example of the mouth portion of the container B, in which an upper view of fig. 19 a to 19C shows a top surface of the mouth portion of the container B (male screws and flanges formed on the outer periphery of the mouth portion are omitted), and a lower view of fig. 19 a to 19C shows a cross section of the mouth portion of the container B (hatching is omitted).

In the example of fig. 19(a), a flange portion 80 protruding inward is formed along the inner peripheral surface of the mouth portion of the container B. The top surface of the flange portion 80 abuts against the peripheral edge portion of the bottom surface of the door portion 75 in a state where the container lid 5 is fastened to the mouth portion of the container B and reaches the bottom. The flange 80 may be provided integrally with the container B, for example.

Of course, the shape of the flange portion 80 is not limited to fig. 19 (a). In the example of fig. 19(B), a part of the flange portion 80 is removed to form four flange portions 81. In the example of fig. 19(C), a part of the flange portion 80 is removed, and eight flange portions 82 are formed. By dividing the flange portion into a plurality of portions, a gap is formed between the respective flange portions. Thus, the additive discharged from the chamber of the container 70 is easily moved downward.

Next, the operation of the container lid 5 will be described in chronological order in the process of removing the container lid 5 from the container.

Fig. 20 is a sectional view showing an example of the operation of the container cover 5, in which fig. 20(a) shows a state where the container cover 5 is fastened and the door portion 75 is closed, fig. 20(B) shows a state where the container cover 5 is loosened, fig. 20(C) shows a state where the container cover 5 is further loosened and the door portion 75 is opened, and fig. 20(D) shows a state where the container cover 5 is further loosened and the door portion 75 is further opened. Fig. 20 shows a section taken along D-D of fig. 16 (a). Further, fig. 20 shows a cross section of the mouth of the container B. In fig. 20, the container B has a flange portion 80 shown in fig. 19 (a).

Fig. 20 (a): first, the container lid 5 with the door portion 75 closed is fastened to the mouth portion of the container B. In this state, the door portion 75 is locked to the flange portion 72 by the locking portion 76. Further, the bottom surface of the door portion 75 abuts the flange portion 80. Therefore, even if the user pinches the upper end portions of the pair of operation levers 60 from the outside and presses them in the inward direction, the lowering of the door portion 75 is restricted, and the operation levers 60 cannot be moved. Further, since the door portion 75 is closed, the additive is prevented from being discharged from the container 70.

Fig. 20 (B): next, when the user pinches the body 50 to rotate it leftward and starts to loosen it, the bottom surface of the door 75 rises along with the rise of the container lid 5 (hollow arrow in the figure), and the contact with the flange 80 is released. In this state, the door portion 75 is locked to the flange portion 72 by the locking portion 76, and the lowering of the door portion 75 is restricted.

Fig. 20 (C): when the user pinches the upper ends of the pair of operation levers 60 from the outside and presses them in the inward direction, the door portion 75 starts to descend together with the ascending/descending wall 52, and the locking portion 76 bends inward and bends to enter the inside of the flange portion 72, thereby releasing the locking. Since the force is applied to the elevating wall 52 in a descending manner, the user can open the door portion 75 by pinching the operation lever 60 with a small force. When the discharge port is opened, the additive is discharged from the chamber of the receiving portion 70. Further, even if the user releases the operating lever 60, the door portion 75 is not closed by the urging force of the operating lever 60 and the connecting wall 53.

Fig. 20 (D): thereafter, when the user further loosens the container lid 1 and further firmly pinches the upper end portion of the operation lever 60, the door portion 75 is further lowered and the discharge port is largely opened.

The fourth embodiment of the present invention has been described above. According to the container lid 5 of the present embodiment, a user can select whether or not an additive is added to the container.

Fig. 21 is a sectional view illustrating a modification of the top surface of the body 50. The rising and falling wall 52 and the connecting wall 53 may be connected by a connecting member 54. The connecting member 54 is formed in a ring shape and bent downward. The coupling member 54 functions as a leaf spring such that the coupling member 54 bends more as the ascending/descending wall 52 descends, and is biased more strongly in the direction of ascending/descending wall 52. Alternatively, the coupling member 54 functions as a leaf spring such that the coupling member 54 bends more as the ascending/descending wall 52 ascends, and is biased more strongly in the direction of descending the ascending/descending wall 52.

Fig. 22 is a sectional view illustrating a modification of the bottom portion of the cylinder portion 73. In a state where the door portion 75 is closed with respect to the cylindrical portion 73, these contact portions (arrows in the drawing) are formed to extend in the vertical direction and then to be bent inward. When the bottom of the cylindrical portion 73 is viewed from below, the contact portion appears as a circular line. By bending the contact portion in this manner, the additive in the container B can be prevented from entering the tube portion 73. Further, the circular contact portion may be sealed with a circular or annular sealing material 90 (e.g., tape). This prevents liquid and gas in the container from entering the cylindrical portion 73.

The locking structure of the door portion 75 is not limited to the locking structure that is locked to the top surface of the flange portion 72 as shown in fig. 17. Fig. 23 is a diagram illustrating a modification of the locking portion. A pair of locking portions 76A are provided on the top surface of the door portion 75 instead of the pair of locking portions 76 shown in fig. 17. The locking portion 76A is formed in a rod shape or a block shape shorter than the locking portion 76, and has a groove. On the other hand, projecting engaging portions 77A are provided on the inner surface of the tube portion 73 at positions corresponding to the pair of engaging portions 76A. The groove of the locking portion 76A and the protrusion of the locking portion 77A are formed to face each other and to be fitted.

As shown in fig. 23(a), in a state where the door portion 75 is closed, the door portion 75 is locked to the tube portion 73 as the locking portion 76A is fitted to the locking portion 77A. As shown in fig. 23(B), when the user pinches the pair of operation levers 60 and presses them in the inward direction, the locking portion 76A bends and curves inward to get over the locking portion 77A, and the locking is released.

In the fourth embodiment, the operation lever 60 and the connection wall 53 have restoring forces to lower the rising and lowering wall 52, but may be configured to have restoring forces to raise the rising and lowering wall 52. Thus, when the user's hand releases the lever 60, the discharge port is automatically closed.

In the fourth embodiment, an attachment member (e.g., an auxiliary cover) having at least one of a member for pressing the operation lever 60 inward and a member for pressing the rising and falling wall 52 downward may be prepared. When the container lid 5 is rotated leftward and starts to be loosened in a state where the attachment member is attached to the container lid 5, at least one of the operation lever 60 and the lifting wall 52 is pressed by a pressing force generated by the attachment member, and the door portion 75 is lowered. Thus, the discharge port is automatically opened.

As still another modification, in the first embodiment, the interior of the housing 20 is divided into two chambers, but may be divided into one chamber or three or more chambers. The components such as the operation lever and the discharge port may be provided corresponding to the respective chambers. The same applies to the second to third embodiments.

The present invention is not limited to the above-described embodiments (and modifications), and various modifications can be made within the scope of the gist of the present invention, and these aspects are included. It is also possible to add or replace a part of the constituent elements of some embodiments with another embodiment. Some of the constituent elements of some embodiments may be omitted.

The configuration of the arrangement, size, shape, and the like of the respective constituent elements of the container lid is not limited to the above description or the illustrated example, as long as the object of the present invention can be achieved. Further, for example, although terms such as "vertical" or the like are used to indicate the relationship and the shape of the constituent elements, they are not limited to the precise meaning of the terms, and may include a case substantially identical to the meaning thereof (that is, a case where the effect of the present invention can be exerted).

The present invention is not limited to the so-called PET bottle, and can be applied to containers of various materials and shapes. The content of the container is not limited to beverages, but may be seasoning, food, medicine, liquid, granular material, or solid material. The additive is not limited to a beverage, but may be a seasoning, a food, a pharmaceutical, a solid or a liquid, or a granular material.
