The outer cover is rotatably attached to the main body with the depending cylindrical wall of the outer cover adjacent to the outer peripheral surface of the protruding cylindrical wall of the main body, and the outer cover has a radially outward direction from the discharge hole. A discharge nozzle is formed that extends to.

<Preferred Embodiments of the Invention> Hereinafter, preferred embodiments of the container lid for large volume and small volume discharge constructed according to the present invention will be described in detail with reference to the accompanying drawings.

(2) Bottom Referring to FIG. 1, the container lid, generally designated by the number 2, consists of a main body 4 and an outer M6. Both the body 4 and the outer M6 may be formed from any suitable synthetic resin such as polyethylene or polypropylene.

The main body 4 will be described with reference to FIG. 2 together with FIG. 1. The main body 4 includes a circular top wall 8, a cylindrical side wall 10 extending downward from the periphery of the top wall 8, and an upper intermediate portion of the top wall 8. and a protruding cylindrical wall 12 extending upwardly from the top. A discharge opening 14 is formed in a central portion of the top wall 8 that is located radially inward of the protruding cylindrical wall 12 . As clearly shown in FIG. 2, the discharge opening 14 preferably has a substantially elliptical shape that extends in a predetermined direction (the left-right direction in FIGS. 1 and 2). If desired, instead of pre-forming the discharge opening 14 in the top wall 8, a line of thin wall weakening, which is known per se, corresponding to the contour of the discharge opening 14 can be formed and the user can break such a weakened line. It is also possible to actually form the discharge opening 14 by doing so. An annular protrusion 16 that protrudes upward is formed on the upper peripheral edge of the top wall 8, and a locking bulge 18 that protrudes radially outward is formed on the outer peripheral surface of the upper end of the annular protrusion 16. is formed. On the other hand, in the middle part of the lower surface of the top wall 8,
Two concentric annular protrusions projecting downward, namely an inner annular protrusion 20 and an outer annular protrusion 22, are formed. The amount of downward protrusion of the inner annular protrusion 20 is relatively large, and the amount of downward protrusion of the outer annular protrusion 22 is relatively small. A female thread 24 is formed at the lower part of the inner circumferential surface of the side wall 10 of the main body 4, and an annular locking protrusion 26 that projects radially inward is formed at the lower end of the inner circumferential surface of the side wall 10. There is.

The protruding cylindrical wall 12 of the main body 4 is provided with a large volume discharge port 2, a small volume discharge port 30, and a ventilation port 32. In the specific example shown, as can be understood by referring to FIG. Defined by an extending notch. The lower ends 34, 36 and 38 of such cutouts are preferably sloped downwardly and radially inwardly. As can be understood by referring to FIG.
The circumferential width of the notch defining the day is relatively large, and the circumferential width of the notch defining the small volume discharge port 30 and the ventilation port 32 is relatively small. The large volume discharge port 28 and the small volume discharge port 30 are arranged at an angular interval of approximately 90 degrees in the circumferential direction, and the large volume discharge port 28 and the ventilation port 32 are arranged at an angular interval of approximately 180 degrees in the circumferential direction. It is preferable that they be arranged separately. The direction in which the large volume discharge port 28 and the ventilation port 32 are connected coincides with the long axis direction of the substantially elliptical discharge opening 14 described above.
Preferably, it extends in a long and narrow direction in the direction connecting the air vent 32 and the air vent 32. An intermediate portion in the vertical direction of the outer peripheral surface of the protruding cylindrical wall 12;
More specifically, an annular sealing ridge 40 is formed slightly below the lower ends 34, 36 and 38 of the notch and projects radially outward. At the lower end of the outer circumferential surface of the protruding cylindrical wall 12, predetermined positions are provided in the circumferential direction corresponding to the large quantity discharge port 28, the intermediate part between the large quantity discharge port 28 and the small quantity discharge port 30, and the angular position of the small quantity discharge port 30, respectively. Pairs of locking protrusions 42, 44 and 46 are formed for the device, which are composed of pairs of protrusions formed at intervals. Furthermore, in the illustrated example, the protruding cylindrical wall 1 on the upper surface of the top wall 8
2 and the annular protrusion 16 are formed with stop protrusions 48 and 50 that protrude upward, corresponding to the angular positions of the large volume discharge port 28 and the small volume discharge port 30, respectively. ing.

The outer cover 6 will be described with reference to FIGS. 3 and 4 as well as FIG. 1. The outer cover 6 includes an upper wall 52, a hanging cylindrical wall 54 extending downward from the middle part of the lower surface of the upper wall 52, Further, although not necessarily required, an outer wall 56 is provided that hangs down from the periphery of the upper wall 52. The upper wall 52
is circular except for one radially outwardly projecting projection 58. On the upper half of the outer peripheral surface of the outer wall 56, an uneven shape 59 for preventing slipping is formed, except for the portion corresponding to the protrusion 58 (FIG. 3). A discharge hole 60 and a ventilation hole 62 are formed in the upper part of the hanging cylindrical wall 54 . The discharge hole 60 and the ventilation hole 62 are approximately 18 mm apart in the circumferential direction.
Preferably, they are arranged at an angular spacing of 0 degrees.

In the illustrated example, the exhaust hole 60 has a rectangular cross-sectional shape and the vent hole 62 has a circular cross-sectional shape. The circumferential width of the discharge hole 60 is the same as that of the large volume discharge port 2 in the main body 4.
The diameter of the vent hole 62 may be substantially the same as the circumferential width of the vent hole 32 in the main body 4 . The above-mentioned discharge hole 60 is provided on the inner peripheral surface of the hanging cylindrical wall 54.
Preferably, a rectangular seal protrusion 64 extending along the outer periphery of the vent hole 62 and an annular seal protrusion 66 extending along the outer periphery of the vent hole 62 are formed. The vertical middle part of the outer circumferential surface of the hanging cylindrical wall 54, more specifically, the discharge hole 60
An annular seal protrusion 68 is formed slightly below the sealing member 68 and protrudes radially inward. The lower end of the hanging cylindrical wall 54 is made somewhat thinner by increasing the inner diameter, and the discharge hole 60 is formed on the inner peripheral surface of the lower end.
A locking protrusion 70 is formed to be positioned corresponding to the angular position. The circumferential width of the locking protrusion 70 corresponds to the circumferential spacing between each of the locking protrusion pairs 42, 44, and 46 on the main body 4.

Also formed in the outer wall 56 of the outer M6 are an outer exhaust hole 72' and an outer ventilation hole 74 that match the angular position and shape of the exhaust hole 60 and ventilation hole 62 formed in the hanging cylindrical wall 54. has been done.

Between the depending cylindrical wall 54 and the outer wall 56 is a channel-shaped wall 78 that cooperates with the lower surface of the upper wall 52 to define a discharge passage 76 extending from the discharge hole 60 to the outer discharge hole 72. A channel-shaped wall 82 is formed in cooperation with the lower surface of the upper wall 52 to define a ventilation path 80 extending from the ventilation hole 62 to the outer ventilation hole 74. Advantageously, the cross-sectional shape of the discharge passage 76 is rectangular, matching the discharge hole 60, and the cross-sectional shape of the ventilation passage 80 is circular, matching the ventilation hole 62.

The discharge passage 76 and the outer discharge hole 72 constitute a discharge nozzle 84 for discharging seasonings and the like, as will become clear from the description below. A stop piece 86 extending downward is formed on the lower surface of the channel-shaped wall 78 defining the discharge passage 76 . This stop piece 86 cooperates with the stop projections 48 and 50 on the body 4, as will be explained in more detail below. An annular locking protrusion 88 is formed at the lower end of the inner peripheral surface of the outer wall 56 and projects radially inward.

The outer M6 as described above is rotatably mounted above the main body 4 as shown in FIG. When the outer cover 6 is attached to the main body 4 as required, the outer wall 5 of the outer M6
The annular locking protrusion 88 formed on the inner circumferential surface of the main body 4 elastically overcomes the locking expansion part 18 formed on the upper outer circumferential surface of the annular protrusion 16 of the main body 4 and is locked below. This prevents the outer cover 6 from separating upward from the main body 4. Furthermore, the annular seal protrusion 68 formed on the inner peripheral surface of the hanging cylindrical wall 54 of the outer M6 elastically pushes the annular seal protrusion 40 formed on the outer peripheral surface of the protruding cylindrical wall 12 of the main body 4. It is made to cross over and make seal contact below it.

In the closed state where the contents of the container such as seasonings are not discharged,
The outer lid 6 for the main body 4 has a locking protrusion 70 formed at the lower end of the inner peripheral surface of the hanging cylindrical wall 54 of the outer M6, and a locking protrusion 70 formed at the lower end of the outer peripheral surface of the protruding cylindrical wall 12 of the main body 4. The locking protrusion 7 is positioned in the closed position between the pair of locking protrusions 44.
0 and the pair of locking protrusions 44 to releasably elastically hold the closed position. When the outer M4 is positioned in the closed position, all of the large volume discharge port 28, small volume discharge port 30, and ventilation port 32 formed in the protruding cylindrical wall 12 of the main body 4 are connected to the hanging cylindrical wall 54 of the outer cover 6. They do not overlap with the formed discharge hole 60 and ventilation hole 62, and the large volume discharge port 28, small volume discharge port 30, and ventilation port 32 are all closed by the hanging cylindrical wall 54 of the outer cover 6, and the discharge hole 60 and the vent hole 62 are both located in the protruding cylindrical wall 1 of the main body 4.
Closed by 2.

When discharging a large amount of container contents such as seasonings, the outer lid 6 is rotated approximately 45 degrees clockwise relative to the main body 4 from the closed position as viewed from above in FIG. 1 to discharge a large amount. position (in FIG. 1, the outer cover 6 is positioned in this mass ejection position), thus the outer M6
A locking protrusion 70 formed at the lower end of the inner circumferential surface of the hanging cylindrical wall 54 is positioned between a pair of locking protrusions 42 formed at the lower end of the outer circumferential surface of the protruding cylindrical wall 12 of the main body 4, The locking protrusion 70 and the pair of locking protrusions 42 cooperate to releasably elastically hold the large quantity discharge position.

In addition, the stop piece 86 formed on the outer M6 comes into contact with or comes close to the stop protrusion 48 formed on the main body 4, so that the outer cover 6 moves beyond the above-mentioned large quantity discharge position and further from above in FIG. Rotation in a clockwise direction is reliably prevented. When the outer M6 is positioned at the large volume discharge position, the discharge hole 60 and the ventilation hole 62 formed in the hanging cylindrical wall 54 of the outer cover 6 are connected to the protruding cylindrical wall 1 of the main body 4, respectively.
2 is aligned with the bulk outlet 28 and the vent 32 formed in 2. . On the other hand, the small amount discharge port 30 formed in the protruding cylindrical wall 12 of the main body 4 is connected to the outside M6 of the hanging cylindrical wall 5.
Closed by 4. In such a situation,
As will be further described later, the shape of the discharge opening 14 formed in the main body 4, the relatively large circumferential width of the bulk discharge port 28, and the presence of ventilation through the vent hole 32 and the vent hole 62. Due to this, the contents of the container such as seasonings are discharged in large quantities from the discharge opening 14, the bulk discharge port 28, and the discharge hole 60 through the discharge nozzle 84.

When discharging a small amount of container contents such as seasonings, use the main body 4.
In contrast, the outer M6 is rotated approximately 45 degrees counterclockwise from the closed position as viewed from above in FIG. In this way, the hanging cylindrical wall 5 of the outer lid 6
A locking protrusion 70 formed at the lower end of the inner circumferential surface of the main body 4 is positioned between a pair of locking protrusions 46 formed at the lower end of the outer circumferential surface of the protruding cylindrical wall 12 of the main body 4. 70 and the pair of locking protrusions 46 cooperate to releasably and elastically hold the small amount discharge position. In addition, the stop piece 86 formed on the outer M6 comes into contact with or comes close to the stop protrusion 50 formed on the main body 4, so that the outer lid 6 moves beyond the small amount ejection position and further from above in FIG. Rotation counterclockwise when viewed is reliably prevented. When the outer lid 6 is positioned at the small volume discharge position, the discharge hole 60 formed in the depending cylindrical wall 54 of the outer lid 6 is aligned with the small volume discharge port 30 formed in the protruding cylindrical wall 12 of the main body 4. . On the other hand, the ventilation hole 62 formed in the hanging cylindrical wall 54 of the outer cover 6 can be inserted into the outside without overlapping with both the large volume discharge port 2 and the ventilation hole 32 formed in the protruding cylindrical wall 12 of the main body 4. The M6 vent hole 62 is closed by the protruding cylindrical wall 12 of the body 4, and the mass outlet 28 and the vent hole 32 of the body 4 are closed.
are closed by a depending cylindrical wall 54 of the outer lid 6.

In such a state, as will be further described later, the shape of the discharge opening 14 formed in the main body 4, the small amount discharge port 3
Due to the relatively small circumferential width of the outlet opening 14 and the fact that the vents 32 and 62 are closed and the ventilation is blocked, in particular the ventilation openings 14, a small amount The contents of the container such as seasonings that are discharged from the discharge port 30 and the discharge hole 60 are extremely small, and if the contents of the container are liquid, they are not discharged continuously but as small droplets.

How to use Next, the container lid 2 consists of a combination of the main body 4 and the outer M6.
We will explain the typical usage of .

Referring to FIG. 5, in a typical mode of use, the container lid 2 is used with a container 90, which may be made of glass or a suitable synthetic resin. The illustrated container 90 has a generally cylindrical neck portion 92 with an open upper end. An annular bead 94 that bulges outward in the radial direction is formed at the upper end of the outer peripheral surface of the mouth portion 92 . A male thread 96 is formed in the vertically intermediate portion of the outer peripheral surface of the mouth and neck portion 92 . Furthermore, an annular locking protrusion 98 is formed at the lower end of the outer circumferential surface of the mouth and neck portion 92 and protrudes radially outward. A so-called metal crown cover 100, which itself may have a well-known form, is attached to the upper end of the mouth and neck part 92, and the crown M10
0, the mouth and neck portion 92 are reliably sealed. The crown M100 has a circular top wall 102 and a pleated skirt wall 104 that hangs down from the periphery of the top wall 102, and the lower part of the skirt wall 104 is displaced radially inward and locked to the annular bead 94. It is being

A liner 106, which may be made of a suitable synthetic resin or cork, is disposed on the inner surface of the top wall 102 and is brought into close contact with the upper end surface of the mouth and neck portion 92.

The container lid 2 is additionally attached to the mouth and neck part 92 sealed by the crown lid 100 and supplied to the user. Attaching the container M2 to the mouth and neck region 92 is accomplished as follows. The container lid 2 is fitted onto the neck portion 92 and rotated clockwise when viewed from above in FIG. In this way, the female thread 24 formed at the lower part of the inner peripheral surface of the side wall 10 of the main body 4 of the container M2 is gradually screwed into the male thread 96 of the mouth portion 92, and thus the container lid 2 is lowered with rotation. Container lid 2
is lowered to the position shown in FIG.
: The lower end of the protrusion 20 contacts the upper surface of the top wall 102 of the crown lid 100 attached to the mouth and neck part 92, thus preventing the container lid 2 from further descending. In this state, the annular locking protrusion 26 formed at the lower end of the inner circumferential surface of the side wall 10 of the main body 4 of the container lid 2 engages the neck portion 9.
The annular locking protrusion 26 and the annular locking protrusion 98 do not cooperate with each other.

As shown in FIG. 5, a user who has purchased a product in which a container lid 2 is additionally attached to a mouth-and-neck part 92 sealed by a crown 1100 may purchase contents such as seasonings contained in a container 90. When using, perform the following preparatory operations. First, the container lid 2 is rotated counterclockwise when viewed from above in FIG. In this way, the threaded engagement between the female thread 24 formed at the lower part of the inner circumferential surface of the side wall 10 of the main body 4 of the container lid 2 and the male thread 96 of the neck part 92 is gradually released, and the container lid 2 is therefore rotated. The container lid 2 is thus removed from the mouth portion 92. Next, the crown M100 is removed from the mouth and neck part 92 using a suitable bottle opener, and the mouth and neck part 92 is unsealed. Thereafter, as shown in FIG. 6, the container lid 2 is fitted onto the neck portion 92 again and rotated clockwise when viewed from above in FIG. The female thread 24 formed at the lower part of the inner peripheral surface of the side wall 10 is connected to the male thread 96 of the neck part 92.
The container M2 is gradually screwed into the container M2, and thus the container M2 descends as it rotates. In this case, since the crown M100 has already been removed from the mouth and neck portion 92, the container M2 is lowered beyond the position shown in FIG. 5 to the position shown in FIG. In the state shown in FIG. 6, the main body 4 of the container M2
Inner annular projection 2 formed on the lower surface of the top wall 8 in
The lower end of the outer circumferential surface of 0 comes into contact with or approaches the upper end of the inner circumferential surface of the mouth and neck part 92, and the lower end of the outer annular projection 22 formed on the lower surface of the top wall 8 comes into close contact with the top surface of the mouth and neck part 92. . Furthermore, the annular locking protrusion 26 formed at the lower end of the inner circumferential surface of the side wall 10 of the main body 4 of the container M2 elastically overcomes the annular locking protrusion 98 of the neck portion 92 and extends below the annular locking protrusion 98. to lock. In this way, the rise of the main body 4 of the container lid 2 is restrained, and therefore, the rotation of the main body 4 in the clockwise direction when viewed from above in FIG. 6 as well as the counterclockwise rotation when viewed from above in FIG. 6 is also restrained. be done. If desired, the sixth locking ridge of the main body 4 can be secured by the cooperation of the annular locking ridge 26 and the annular locking ridge 98.
Instead of restricting rotation in the counterclockwise direction when viewed from above in the figure, for example, a so-called ratchet may be formed at the lower end of the outer peripheral surface of the mouth and neck portion 92 and at the lower end of the inner peripheral surface of the side wall 10 of the main body 4. It is also possible to form a so-called ratchet pawl, and by the cooperation between the ratchet and the ratchet pawl, rotation of the main body 4 in the counterclockwise direction when viewed from above in FIG. 6 can be restrained.

The preparation operation for use is completed as described above.

When the contents stored in the container 90 are not actually discharged, the outer lid 6 of the container M2 is positioned at the above-mentioned closed position with respect to the main body 4. In such a state, as described above (the large volume discharge port 28, the small volume discharge port 30, and the ventilation port 32 formed in the protruding cylindrical wall 12 of the main body 4 are all formed in the hanging cylindrical wall 54 of the outer M6). They do not overlap with the discharge hole 60 and the ventilation hole 62, and the large volume evacuation outlet 28, the small volume discharge port 30, and the ventilation port 32 are all closed by the hanging cylindrical wall 54 of outer M6,
Both the exhaust hole 60 and the ventilation hole 62 are closed by the protruding cylindrical wall 12 of the body 4. Therefore, the contents contained in the container 90 will not be discharged.

When discharging a large amount of the contents contained in the container 90, the outer lid 6 of the container lid 2 is moved approximately 45 degrees clockwise from the closed position to the main body 4 when viewed from above in FIG.
It is rotated once and positioned at the above-mentioned large-volume discharge position (in FIG. 6, the outer M6 is positioned at the large-volume discharge position). Thus, as described above, the discharge hole 60 and the ventilation hole 62 formed in the hanging cylindrical wall 54 of the outer M6 are connected to the mass discharge port 28 and the ventilation hole 32 formed in the protruding cylindrical wall 12 of the main body 4, respectively. It is made to be consistent with. on the other hand,
A small amount outlet 3 formed in the protruding cylindrical wall 12 of the main body 4
0 is closed by a depending cylindrical wall 54 of the outer lid 6. In such a state, hold the container 90 and close the container lid 2.
When the discharge nozzle 84 is tilted downward,
The discharge opening 14 formed in the main body 4 has a shape elongated in the direction in which the outer M6 discharge nozzle 84 positioned at the large volume discharge position extends, and the width of the large volume discharge port 28 in the circumferential direction is relatively large. In addition, due to the venting facilitated by the venting achieved through vents 32 and 62, the contents within container 90 are transferred to drain openings 14, bulk vents 28, and vents 60. From discharge nozzle 84
is discharged in sufficient quantity through the

When discharging a small amount of the contents contained in the container 90, the outer M6 of the container lid 2 is moved approximately 45 degrees counterclockwise from the closed position to the main body 4 when viewed from above in FIG.
Rotate it once and position it at the small amount discharge position mentioned above. Thus, as described above, the discharge hole 60 formed in the depending cylindrical wall 54 of the outer lid 6 is aligned with the small volume discharge port 30 formed in the protruding cylindrical wall 12 of the main body 4. On the other hand, a ventilation hole 62 formed in the hanging cylindrical wall 54 of the outer lid 6
The outer M is not superimposed on both the mass discharge port 28 and the ventilation port 32 formed in the protruding cylindrical wall 12 of the main body 4.
6 are closed by the protruding cylindrical wall 12 of the body 4, and both the bulk outlet 28 and the vent 32 of the body 4 are closed by the depending cylindrical wall 54 of the outer lid 6. In such a state, if the container 90 is gripped and tilted in a direction in which the discharge nozzle 84 of the container lid 2 is directed downward, and if necessary, the container 90 is also vibrated, the contents of the container 90 will flow through the discharge opening 14. , a small amount discharge port 30, and a discharge hole 60 through a discharge nozzle 84. The discharge of the contents is carried out by ensuring that the discharge opening 14 formed in the main body 4 has a short shape in the extending direction of the discharge nozzle 84 of the outer lid 6 positioned at the small quantity discharge position, and that the small quantity discharge port 30 In addition to the relatively small width in the circumferential direction of In the case of liquids, it is not ejected continuously but as small droplets.

<Effects of the Invention> As described above, according to the container M2 configured according to the present invention, it is possible to sufficiently increase the difference in the amount of discharge between a large quantity discharge and a small quantity discharge, and in the case of a small quantity discharge,
For example, in the case of a liquid, it can be ejected in small droplets rather than continuously. In addition, the method of use is straightforward, and even if the user is unfamiliar with the method, he or she can use it properly without making mistakes.
