Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a variable discharge direction container lid that can change the discharge direction of liquid, etc.

[Conventional technology]

As is well known to those skilled in the art, a container lid applied to the mouth and neck of a container containing cleaning liquid, etc. requires at least a portion of the container lid to be placed against the mouth and neck without completely removing the container lid from the mouth and neck. The cleaning liquid etc. can be discharged through the container lid as long as the container is moved in the correct direction. Recently, for the convenience of general users, it has become possible to change the discharge direction of the cleaning liquid etc. discharged through the container lid (for example, when the container is held upright, the direction of discharge can be changed upward or horizontally). There is an increasing desire to be able to make changes.

An example of a container lid that satisfies these requirements is:
For example, the container lid disclosed in Japanese Utility Model Publication No. 54-16782 can be mentioned. Such a container lid includes a lid main body and a spouting stopper, and the spouting stopper is rotatably attached to a cylindrical portion provided on the lid main body. Two holes are formed at intervals in the cylindrical part of the lid body,
Further, the spouting stopper is provided with a spouting tube in which a discharge path is formed. When the spout tap is positioned at a specific angle, the spout tube protrudes above the lid body, and the discharge path of the spout tube communicates with one of the holes in the tube, thus discharging the contents such as cleaning liquid into the lid body. can be discharged in the axial direction. Furthermore, when the spouting stopper is rotated substantially 180 degrees from the specific angular position, the spouting tube protrudes in the lateral direction of the lid body, and the discharge passage of the spouting tube communicates with the other hole of the cylindrical portion. The contents can thus be discharged in a direction substantially perpendicular to the axial direction of the lid body.

[Disadvantages of conventional technology]

However, the above-mentioned known container lid has the following drawbacks.

First, the lid body has a configuration in which a conical recess is formed at one edge of the upper end and a substantially conical cylindrical portion is provided in the center of the recess. Therefore, the shape of the lid body It is complicated, has poor moldability, and cannot be manufactured easily.

Secondly, the contact surface between the lid body and the spout tap (the sliding surface of both) is conical, and therefore it is difficult to manufacture these contact surfaces with high precision, and it is difficult to make the contact surfaces between the two contact surfaces sufficiently securely. Difficult to seal.

Thirdly, the spout is attached to one edge of the upper end of the lid body, and therefore the spout cannot be sufficiently photographed, resulting in poor operability.

[Technical issues of invention]

The present invention allows the inner lid attached to the mouth and neck of the container and the outer lid attached to the inner lid to be easily manufactured using a relatively simple mold, and also provides a seal between both contact surfaces. The technical problem is to create a structure that can ensure sufficient performance and provide even better operability.

[Means to solve the problem]

The solution of the present invention is to provide the inner lid with a discharge tube portion having a cylindrical large-diameter lower portion and a small-diameter upper portion that protrude upward, and a shoulder wall existing at the boundary between these portions; providing the outer lid with a fitting recess having a large-diameter lower part having an inner diameter corresponding to the diameter, a small-diameter upper part having an inner diameter corresponding to the outer diameter of the small-diameter upper part of the discharge cylinder part, and a shoulder surface existing at the boundary thereof; A first discharge passage whose outlet opens in the horizontal direction and a second discharge passage whose outlet opens upward are formed in the outer cover; The fitting recess is rotatably attached to the large-diameter lower part and the small-diameter upper part of the inner lid so as to be rotatable about an axis extending in the vertical direction.

[Effect]

In the container lid equipped with the above-mentioned means, the contact surface between the discharge cylinder part of the inner lid, especially the large diameter lower part, the small diameter upper part, and the shoulder wall and the fitted recess of the outer lid, especially the large diameter lower part, the small diameter upper part, and the shoulder surface. Since it is composed of a cylindrical curved surface and a flat surface, the inner lid and outer lid can be easily manufactured using a relatively simple mold. Further, since the discharge cylinder part of the inner lid and the fitting recess part of the outer lid are in contact with each other on the cylindrical curved surface and the flat surface, it is possible to seal the contact surfaces sufficiently reliably. In addition, since the outer cover is rotatably mounted around an axis extending in the vertical direction so as to cover at least the upper part of the ejection cylinder part of the inner cover, it is easy to grasp the part of the outer cover that covers at least the upper part of the ejection cylinder part. It is easy to use and has good operability.

〔Example〕

Hereinafter, a specific example of a container lid constructed in accordance with the present invention will be described in more detail with reference to the accompanying drawings.

Referring to FIG. 1, the container lid, generally designated by the number 2, includes an inner lid 4 and an outer lid 6. As shown in FIG. The inner lid 4 and the outer lid 6 can be separately molded from a suitable synthetic resin such as polypropylene or polyethylene by injection molding, compression molding, or the like.

Referring to FIG. 2 together with FIG. 1, the illustrated inner lid 4 has an annular top wall 8 and a skirt wall 10 depending from the outer peripheral edge of the top wall 8. As shown in FIG. A female thread 12 is formed on the inner circumferential surface of the skirt wall 10 at an intermediate portion in the vertical direction, and an annular locking protrusion 14 is formed on the lower inner circumferential surface of the skirt wall 10 . An annular protrusion 16 that protrudes upward is provided on the outer periphery of the upper surface of the top wall 8.
An annular locking protrusion 18 is formed on the outer peripheral surface of the upper end of the annular protrusion 16 . Two annular seal protrusions 20 and 22 located adjacent to each other are formed on the outer periphery of the lower surface of the top wall 8 .
Further, the annular seal protrusion 2 is provided on the lower surface of the top wall 8.
An annular protrusion 24 that hangs downward is also formed on the inner side of 0 and 22. A discharge tube portion 26 is provided at the inner peripheral edge of the top wall 8 and extends upward therefrom. The ejection barrel 26 in the illustrated embodiment is cylindrical and has a large diameter lower portion 28 having relatively large outer and inner diameters and a small diameter upper portion 30 having relatively small outer and inner diameters. Large diameter lower part 28
An annular shoulder wall 32 exists at the boundary between the small diameter upper part 30 and the small diameter upper part 30, and a top wall 34 exists on the top surface of the small diameter upper part 30. It is important that a discharge opening 36 is formed at a predetermined angular position A in the upper part of the discharge tube part 26. In the illustrated embodiment, the discharge opening 36 is located between the top wall 34 and the small-diameter upper portion 30 at a predetermined angular position A.
It is formed across the circumferential side wall of and the shoulder wall 32. In the illustrated example, a mark 38, which may be a protrusion, is further provided on the outer peripheral surface of the upper end of the skirt wall 10 in alignment with the predetermined angular position A where the discharge opening 36 is formed. . Further, on the outer circumferential surface of the large-diameter lower portion 28 of the discharge cylinder portion 26, there is a position aligned with the predetermined angular position A of the discharge opening 36, and two positions substantially spaced apart at angular intervals of 120 degrees on both sides in the circumferential direction from this position. and a substantially hemispherical locking recess 40 (only one of which is shown in FIG. 1).
is formed.

Next, the outer lid 6 will be explained with reference to FIGS. 1 and 2. The illustrated outer lid 6 has a main portion 42 having a substantially cylindrical shape. The upper part of this main portion 42 is formed into a substantially hemispherical shape. The outer lid 6 further includes a generally bell-shaped skirt wall 44 extending downward from the generally hemispherical upper portion of the main portion 42 and beyond the lower end of the main portion 42 . An annular locking protrusion 46 is provided on the inner peripheral surface of the lower end of the skirt wall 44.
is formed. The main portion 42 has a fitting recess 48 that is open on the lower surface thereof. The illustrated fitting recess 48 has a large diameter lower portion 50 having a relatively large inner diameter and a small diameter upper portion 52 having a relatively small inner diameter. The inner diameter of the large-diameter lower part 50 corresponds to the outer diameter of the large-diameter lower part 28 of the discharge cylinder part 26 in the inner lid 4, and the inner diameter of the small-diameter upper part 52 corresponds to the outer diameter of the large-diameter lower part 28 of the discharge cylinder part 26 in the inner lid 4.
This corresponds to the outer diameter of the small diameter upper portion 30 of the discharge cylinder portion 26 in . A shoulder surface 54 exists at the boundary between the large diameter lower part 50 and the small diameter upper part 52. As shown in FIGS. 1 and 3, on the substantially hemispherical upper surface of the main portion 42, a first
A protrusion 56 located at an angular position B, and a protrusion 58 located at a second angular position C are formed.
Advantageously, the first angular position B and the second angular position CC are located at an angular distance of substantially 120 degrees. Protrusion 56 has a substantially vertical end face 60 and protrusion 58 has a substantially horizontal end face 62. As shown in FIG. 4, at the first angular position B, a first discharge passage 64 is formed that passes through the main portion 42 and has an outlet opening laterally.
The first discharge passage 64 in the illustrated example extends substantially horizontally from an inlet opening on the side surface of the small-diameter upper portion 52 of the fitting recess 48 to an outlet opening on the end surface 60 of the protrusion 56 . As shown in Figure 5,
At the second angular position C, a second discharge path 66 is formed that passes through the main portion 42 and has an outlet opening upward. The second discharge path 66 in the illustrated example extends substantially vertically from an inlet opening in the shoulder surface 54 of the fitting recess 48 to an outlet opening in the end surface 62 of the protrusion 58 . In the specific example shown, as best shown in FIG. The first angular position B and the second angular position C
marks 68, which may be protrusions, each located at a third angular position D having an angular spacing of substantially 120 degrees relative to the
B, 68C and 68D are applied. Further, on the side surface of the large-diameter lower portion 50 of the fitting recess 48, substantially hemispherical engagements are located at the first angular position B, the second angular position C, and the second angular position D, respectively. A stop projection 70 is formed (see FIGS. 2, 4 and 5). As will become clear from the description that follows, the locking protrusion 70 cooperates with the locking recess 40 formed on the outer circumferential surface of the large-diameter lower portion 28 of the discharge tube portion 26 in the inner lid 4, and This constitutes a restraining means for restraining the rotation of the outer cover 6 relative to the outer cover 4. If desired, the inner cover 4 may be formed with a locking projection and the outer cover 6 may be formed with a locking recess, quite contrary to the illustrated embodiment. Moreover, it is not necessarily necessary to form three locking protrusions 70, and only one locking protrusion 70 may be used. In the specific example illustrated, the skirt wall 44 further includes at least one, preferably a plurality of, protruding laterally at predetermined angular intervals on the outer peripheral surface of the skirt wall 44 (in the illustrated case, at angular intervals of substantially 180 degrees). Leave 2
) rotating blades 72 are provided.

The container lid 2 comprising an inner lid 4 and an outer lid 6 as described above is applied to a container having a neck 74 of a form known per se as illustrated in FIG. A male thread 76 and an annular locking protrusion 78 located below the male thread 76 are formed on the outer peripheral surface of the mouth and neck portion 74 . The entire container including the neck and neck portion 74 can be formed from a suitable synthetic resin such as polyethylene by injection molding, blow molding, or the like. Such a container has a relatively flexible main portion and can be deformed by manual pressure by the user. Advantageously, it is in the form of what is commonly referred to as a squeeze bottle.

As shown in FIG. 2, the inner lid 4 is attached to the mouth and neck part 74. More specifically, the inner lid 4 has an inverted cup-shaped portion defined by the top wall 8 and the skirt wall 10 that fits over the neck portion 74, and the inner lid 4 is inserted into the neck portion 74 as shown in FIG. It is attached to the mouth and neck part 74 by rotating it clockwise when viewed from above. When the inner lid 4 is rotated in the above direction with respect to the neck part 74, the female thread 12 formed on the inner circumferential surface of the skirt wall 10 of the inner lid 4 is turned into the male thread formed on the outer circumferential surface of the neck part 74. It is screwed into the thread 76, so that the inner lid 4 is moved downward as it rotates. When the female thread 12 is fully screwed into the male thread 76, the annular locking protrusion 14 formed on the inner circumferential surface of the lower part of the skirt wall 10 engages with the annular locking protrusion 14 formed on the outer circumferential surface of the neck portion 74. It passes over the locking protrusion 78 and is locked below it. Thus, the mouth and neck region 74
The upward movement of the inner cover 4 relative to the inner cover 4, and therefore the counterclockwise rotation as viewed from above in FIG. 2, is sufficiently and reliably prevented. Furthermore, two annular seal protrusions 20 and 2 formed on the lower surface of the top wall 8 of the inner lid 4
2 is pressed against the top surface of the neck part 74, and the annular protrusion 24 hangs down from the lower surface of the top wall 8 of the inner lid 4.
The outer circumferential surface of the container is brought into close contact with the inner circumferential surface of the neck part 74, and thus leakage of the contents contained in the container through the gap between the neck part 74 and the inner lid 4 is sufficiently reliably prevented. .

The outer cover 6 is fitted into the discharge tube part 26 of the inner cover 4 and forced downward, so that the outer cover 6 is installed in the state shown in FIG. 2. In the state shown in FIG. 2, the upper end portion of the large diameter lower portion 28 of the discharge cylinder portion 26 of the inner lid 4 is received in the fitting recess 48 formed in the main portion 42 of the outer lid 6. is,
The main portion 42 covers the discharge cylinder portion 26. Further, the annular locking protrusion 46 formed on the inner peripheral surface of the lower end of the skirt wall 44 of the outer lid 6 engages the annular locking protrusion 18 formed on the upper end outer peripheral surface of the annular protrusion 16 of the inner lid 4. The outer cover 6 is moved over the inner cover 4 and is locked below it, thereby sufficiently reliably preventing upward movement of the outer cover 6 with respect to the inner cover 4. In this way, the outer cover 6 is attached to the inner cover 4 so as to be rotatable about the central axis extending in the vertical direction.

Therefore, in normal cases when the contents stored in the container are not consumed, the outer lid 6 is separated from the inner lid 4.
is positioned at a closed angular position where the third angular position D of the outer lid 6 is aligned with the predetermined angular position A of the inner lid 4 (that is, the angular position A where the discharge opening 36 is formed). When the outer cover 6 is positioned at the closed angle position with respect to the inner cover 4, the second
As shown in the figure, the discharge opening 36 formed in the upper part of the discharge cylinder part 26 of the inner lid 4 is closed by the main part 42 of the outer lid 6, so that the contents are not transferred to the container lid 2.
It is not discharged through. In the illustrated example, when the outer cover 6 is positioned at the above-mentioned closed angle position, the inner cover 4 as shown in FIG.
The mark 68D formed on the outer circumferential surface of the lower end of the skirt wall 44 of the outer lid 6 is aligned with the mark 38 formed on the outer circumferential surface of the upper end of the skirt wall 10 of It can be easily and reliably recognized that the outer lid 6 is positioned at the closed angle position. If desired, the indicia 68D can be labeled with a word such as "closed." Further, the above-mentioned locking recess 40 cooperates to constitute a restraining means.
and the locking protrusion 70 are engaged with each other, so that free rotation of the outer cover 6 with respect to the inner cover 4 is sufficiently and reliably prevented.

When it is desired to discharge the contents housed in the container, the locking recess 40 and the locking protrusion 70 engage with each other to resist the restraint effect caused by the cooperation of the locking recess 40 and the locking projection 70. The outer cover 6 is rotated relative to the inner cover 4, and the first angular position B of the outer cover 6 is aligned with the predetermined angular position A of the inner cover 4, or the inner cover 4 is moved to the above-mentioned position. The outer cover 6 may be selectively positioned at any of the second open angular positions where the second angular position C of the outer cover 6 is aligned with the predetermined angular position A. When rotating the outer lid 6, fingers can be placed on the rotating blades 72 provided on the outer circumferential surface of the skirt wall 44, and thus the cleaning liquid etc. discharged through the container lid 2 can be sufficiently easily rotated. The outer cover 6 can be rotated without fear of touching the protrusions 56 and 58 to which may be attached.

When the outer cover 6 is positioned at the first opening angle position, the entrance of the first discharge passage 64 formed in the main portion 42 of the outer cover 6 is connected to the inner cover 4 as shown in FIG. A discharge opening 36 formed in the cylindrical portion 26
communicate with. Through the discharge opening 36 and the first discharge channel 64, the contents contained in the container can thus be discharged laterally when viewed from the upright position of the container. In the illustrated example,
When the outer cover 6 is positioned at the first opening angle position, as shown in FIG. The marks 68B provided on the outer peripheral surface of the lower end of the skirt wall 44 are aligned and the user can easily and reliably recognize that the outer lid 6 is positioned at the first opening angle position. be able to. If desired, the indicia 68B can be labeled with a phrase such as "laterally open." Further, the locking recess 40 and the locking protrusion 70, which work together to constitute a restraining means, engage with each other again, and therefore the outer cover 6 can freely rotate with respect to the inner cover 4. is sufficiently prevented.

On the other hand, when the outer cover 6 is positioned at the second opening angle position, as shown in FIG.
The entrance of the second discharge passage 66 formed in 2 is
It communicates with a discharge opening 36 formed in the discharge tube portion 26 of the inner lid 4 . Therefore, the discharge opening 36 and the second
Through the discharge channel 66, the contents contained in the container can be discharged upwards when the container is in an upright position. In the illustrated example, when the outer cover 6 is positioned at the second opening angle position, a mark 38 formed on the outer peripheral surface of the upper end of the skirt wall 10 of the inner cover 4 as shown in FIG. The mark 68C provided on the outer peripheral surface of the lower end of the skirt wall 44 of the outer cover 6 is aligned with the outer circumferential surface of the skirt wall 44 of the outer cover 6, and therefore the user can confirm that the outer cover 6 is positioned at the second opening angle position. can be easily and reliably recognized. If desired, the indicia 68C can be labeled with a phrase such as "open on top." Further, the locking recess 40 and the locking protrusion 70, which work together to constitute a restraining means, engage with each other again, and therefore the outer cover 6 can freely rotate with respect to the inner cover 4. is prevented with sufficient certainty.

Although one specific example of a container lid constructed according to the present invention has been described above in detail with reference to FIGS. 1 to 5, the present invention is not limited to such a specific example; It goes without saying that various modifications and modifications can be made without departing from the scope of the invention.

For example, in the specific example described above, when the outer cover 6 is placed in the first open angle position shown in FIG. It forms a relatively large discharge opening 36 with which the inlet of the second discharge passage 66 can communicate when the outer lid 6 is placed in the second open angular position shown in FIG. However, if desired, instead of this, as shown in FIG.
When the outer lid 6 is placed in the first opening angle position shown in FIG. It is also possible to form a relatively small second discharge opening 36b with which the inlet of the second discharge passage 66 communicates when the second discharge opening 36b is in the second open angular position.

[Effect of idea]

According to the present invention, when the outer cover rotatably attached to the inner cover is positioned at the first opening angle position, the inlet of the first discharge path is communicated with the discharge opening, and the outer cover is rotated. When positioned at the second opening angle position, the inlet of the second discharge path is communicated with the discharge opening, so that by rotating the outer lid, the direction of discharge of the contents stored in the container can be changed.

In addition, the contact surface between the discharge cylinder part of the inner lid, especially the large diameter lower part, the small diameter upper part, and the shoulder wall and the outer lid's fitting recess, especially the large diameter lower part, the small diameter upper part, and the shoulder surface, is composed of a cylindrical curved surface and a flat surface. Therefore, the inner lid and the outer lid can be easily manufactured using relatively simple molds, and sufficient sealing performance between both contact surfaces can be obtained.

Further, since the outer cover is rotatably mounted around an axis extending in the vertical direction so as to cover at least the upper part of the ejection cylinder part of the inner cover, the part of the outer cover that covers at least the upper part of the ejection cylinder part can be easily grasped. It also has good operability when changing the discharge direction.
