[0001]
[Industrial applications]
The present invention relates to a container lid used for a container filled with various liquids, and particularly to a container lid capable of pouring out a content liquid.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a container lid for liquid pouring, a lid composed of a cap body attached to a container mouth and an upper lid hingedly connected to the cap body and provided rotatably has been widely used. In this type of container lid, the cap main body is composed of a cylindrical side wall and a ceiling wall formed at an upper end portion of the cylindrical side wall, and an upper end of the cap body extends outward on the upper surface of the ceiling wall. In the ceiling wall defined by the circumferential projections, a score capable of forming a liquid discharging opening and a score for tearing the score to form a liquid discharging opening are formed. A tear tab is provided, and the upper lid includes a top surface and a skirt wall hanging down from a periphery of the top surface, and is hinged to a peripheral edge of the ceiling wall at a lower end of the skirt wall, and the upper lid is closed. In this state, the lower end surface of the skirt wall is in contact with the upper surface of the peripheral edge of the ceiling wall.
[0003]
In this type of container lid, when the upper lid is opened and the liquid is poured out, when the upper lid is closed, the peripheral wall of the ceiling wall is dropped by the tip of the circumferential projection serving as a guide for liquid pour-out. There is a problem that the liquid adhering to the splatters scatters and stains the clothes and the like of the user. That is, when the upper lid is closed, the lower end of the skirt wall comes into close contact with the peripheral edge of the ceiling wall, so that the liquid adhering thereto is repelled.
[0004]
As a solution to such a problem, for example, Japanese Utility Model Laid-Open Publication No. 63-144457 discloses that, when the upper lid is closed, the peripheral projection (nozzle) serving as a guide for liquid pouring is positioned around the circumferential projection (nozzle). There has been proposed a container lid in which a suitable scattering prevention wall is provided on the inner surface of the top of the upper lid.
[0005]
There is also known a container lid in which the liquid is prevented from scattering by killing the turning speed of the upper lid when the lid is closed.
[0006]
[Problems to be solved by the invention]
However, in the container lid disclosed in Japanese Utility Model Laid-Open Publication No. 63-144457, the degree of scattering of the liquid can be suppressed to some extent, but the scattering of the liquid flowing out to the peripheral edge of the ceiling wall outside the scattering prevention wall is prevented. It could not be prevented and there is still room for improvement.
In addition, the container lid of the type in which the turning speed of the upper lid is killed has a problem that the commercial value is impaired because there is no feeling of closing the lid.
[0007]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a container lid in which scattering of liquid flowing out to a peripheral portion of a ceiling wall when an upper lid is closed is effectively prevented without impairing a feeling of closing.

[0009]
[Action]
In the present invention, the lower end surface of the skirt wall of the upper lid is in contact with the cap body over at least a half-peripheral portion including a portion (corresponding to a liquid pouring portion) opposite to the hinge connection portion with the upper lid at the periphery of the ceiling wall of the cap body. Is an important feature that is provided so as not to contact. That is, when the upper lid is closed, the closed state of the upper lid is maintained by the engagement of the engagement protrusion formed on the circumferential vertical surface of the circumferential concave portion provided on the inner surface of the skirt wall with the annular convex portion of the cap body. Further, the horizontal surface of the circumferential concave portion comes into contact with the upper end of the annular convex portion to give a lid-closing feeling, but since the lower end surface of the skirt wall is not in contact with the cap body, the peripheral portion serving as a guide for liquid pouring out is provided. Even if the upper lid is closed in a state where the liquid is dripping from the periphery of the projection, splashing of the liquid from the annular convex portion is blocked by the inner surface of the skirt wall, and adheres to the peripheral edge of the ceiling wall of the cap body. There is no splattering of the liquid.
[0010]
In addition, the contact between the horizontal surface of the circumferential concave portion and the upper end of the annular convex portion can be performed at a normal speed without reducing the closing speed of the upper lid, so that the container lid does not lose its closing feeling and can be closed. There is no loss of commercial value.
[0011]
In the present invention, the annular convex portion is formed of a horizontal surface formed toward the outer root portion of the circumferential protrusion serving as a guide for liquid pouring, and a substantially vertical surface connected to the horizontal surface. Is preferred. In this case, even if the discharged liquid drips to the outside of the circumferential projection, the discharged liquid does not accumulate, and even if the discharged liquid adheres, it can be easily wiped. Therefore, it is advantageous in terms of hygiene.
[0012]
Further, in the present invention, the annular projection may be a projection formed at a distance from the circumferential projection of the liquid discharging guide. In this case, the resin weight can be reduced, which is advantageous in cost.
[0013]

1 to 4, the container lid of the present invention comprises a cap main body 1 fixed to a mouth (not shown) of the container, and an upper lid 2 hingedly connected to the cap main body 1 (1a).
[0015]
The cap body 1 includes a cylindrical side wall 3 and a ceiling wall 4 formed at an upper end of the cylindrical side wall 3. On the inner surface of the ceiling wall 4, a cylindrical projection 5 is formed which extends downward at a distance from the cylindrical side wall 3. That is, the mouth of the container is inserted between the cylindrical side wall 3 and the cylindrical protrusion 5, and the cap body 1 is fixed to the jaw of the container mouth by the convex portion formed on the inner surface of the cylindrical side wall 3. Things. Of course, without forming such a convex part, it is also possible to provide a screw-like projection on the inner surface of the cylindrical side wall 3 and fix the cap body 1 to the container mouth by screw engagement with the outer surface of the mouth of the container. is there.
[0016]
A circumferential projection 6 is formed on the upper surface of the ceiling wall 4, and an upper end 6a of the circumferential projection 6 is in a state of expanding outward. A score 7 and a score tearing tab 8 that can form a liquid pouring opening are provided in the ceiling wall 4 defined by the circumferential projections 6. That is, when the tab 8 is pulled up, the score 7 is torn and an opening for liquid injection is formed. Therefore, the above-mentioned circumferential projection 6 serves as a guide for pouring when the liquid in the container is poured out. Due to the outward spread of the upper end 6a, the liquid drips from the upper end 6a. Is prevented as much as possible.
[0017]
The circumferential projection 6 serving as the liquid pouring guide has a high half-peripheral portion on the side opposite to the hinge connecting portion 1a and a short half-peripheral portion on the hinge connecting portion 1a side. This is to allow the inner ring 23 on the inner surface of the upper lid, which will be described later, to be smoothly inserted into the circumferential projection 6 when the upper lid is closed. In addition, the length of the inner ring 23 can be increased, and the liquid collected in the upper lid when the container is shaken can be quickly returned to the container. Further, since the liquid is poured out at a half-periphery portion opposite to the hinge connection portion 1a, there is no problem even if the half-periphery portion at the hinge connection portion 1a side is short.
[0018]
The peripheral portion 4a of the ceiling wall 4 is formed of a flat surface, and an annular convex portion 10 is formed between the peripheral portion 4a and the outer root portion of the peripheral protrusion 6. As is particularly apparent from FIG. 1, the annular convex portion 10 has a horizontal surface 10 a formed toward the outer root portion of the peripheral protrusion 6 and a vertical surface 10 b extending toward the peripheral edge portion 4 a. In the upper part of the vertical surface 10b, a circumferential locking projection 10c is formed. The function of the annular projection 10 will be described later.
[0019]
The upper lid 2 includes a top surface 20 and a skirt wall 21 hanging down from the periphery of the top surface 20. The skirt wall 21 is connected at its lower end to the peripheral edge 4a of the ceiling wall 4 of the cap body 1 by a hinge 1a, and is held so as to be pivotable. A knob piece 22 is provided on a portion of the skirt wall 21 located on the opposite side of the hinge connection portion 1a so that the closed upper lid 2 can be easily opened by hand.
[0020]
An inner ring 23 is provided on the inner surface of the top surface 20. As is understood from FIG. 1, the inner ring 23 is inserted into the circumferential projection 6 provided on the cap body when the upper lid 2 is closed, and closely adheres to the inner surface of the projection 6 to form a seal. Things.
[0021]
In the present invention, a circumferential concave portion 24 is formed on the inner surface of the skirt wall 21 of the upper lid 2, and the circumferential concave portion 24 comes into contact with and engages with the annular convex portion 10, thereby providing a feeling of closing the lid. Provided, and the upper lid 2 is kept closed. In this state, the lower end surface 21a of the skirt wall 21 is not in contact with the cap body 1.
[0022]
In FIG. 4 showing a main part of the container lid, the circumferential concave portion 24 is composed of a horizontal surface 24a and a vertical surface 24b connected thereto, and the vertical surface 24b is formed with a circumferential locking projection 24c. I have. That is, when the upper lid is closed, the projection 24c rides over the locking projection 10c formed on the annular projection 10 of the cap body 1, and the horizontal plane 24a contacts the horizontal plane 10a formed on the annular projection 10. The upper cover 2 is kept in a closed state. In this case, the upper lid 2 that has been turned at a constant speed is immediately locked by the face-to-face contact between the horizontal surface 24a and the horizontal surface 10a, so that a clear lid closing feeling is given to the user.
[0023]
Further, in the present invention, since the position of the upper lid 2 is fixed using the circumferential concave portion 24 provided on the inner surface of the skirt wall 21 as described above, the lower end surface 21a of the skirt wall 21 is That is, the peripheral wall 4a of the ceiling wall 4 is kept in a non-contact state. Therefore, even if the liquid hangs down from the upper end of the circumferential projection 6 serving as a liquid pouring guide and adheres to the peripheral edge portion 4a, there is no possibility that the liquid is scattered.
[0024]
The distance d between the lower end surface 21a of the skirt wall 21 and the peripheral edge 4a of the ceiling wall 4 is arbitrary as long as they are not in contact with each other. However, if they are too close, the liquid adhering to the peripheral edge 4a may be scattered. Sometimes. Therefore, it is usually set to about 0.4 mm or more. Further, in order to provide a sense of stability by making the gap between the upper lid 2 and the cap body 1 invisible from the outside, a hinge connection portion is provided on the lower end surface 21a of the skirt wall 21 so as to correspond to the outermost portion of the peripheral edge portion 4a. The cover projection 25 may be provided over substantially the entire periphery except for the projection. In this case, the interval between the cover projection 25 and the peripheral edge 4a may be set to about 0.1 mm.
[0025]
In the above-described container lid of the present invention, since a concave portion is not formed at all from the outer root portion of the peripheral projection 6 serving as a guide for liquid pouring to the peripheral portion 4a of the ceiling wall 4, There is an advantage that the liquid dripping from the upper end of the circumferential projection 6 does not accumulate, and the attached liquid can be easily removed by wiping.
[0026]
The present invention is not limited to the embodiments shown in FIGS. 1 to 4 described above, and various modifications are possible. The main part of such another embodiment of the container lid is shown in FIGS.
[0027]
For example, the container lid shown in FIG. 5 uses a circumferential projection formed at a distance from the root of the circumferential projection 6 as the above-mentioned annular projection 10. This embodiment differs from the container lids of FIGS. 1 to 4 in that a concave portion 30 is formed at the outer root portion of the circumferential projection 6. That is, the container lid of FIG. 5 has a structure in which the outer root portion of the circumferential projection 6 of the container lid of FIGS. 1 to 4 is hollowed out, so that the weight per unit area of the resin can be reduced, which is advantageous in terms of cost and the like. is there. In addition, the concave portion 30 can be narrow at a half-peripheral portion on the opposite side to the hinge connecting portion 1a, and can be widened toward the hinge connecting portion 1a. That is, since the liquid is not substantially poured out on the hinge connecting portion 1a side, even if the concave portion 30 is enlarged, there is no possibility that the liquid flows out from this portion, and the weight per unit area of the resin can be further reduced. You can.
[0028]
The container lid shown in FIG. 6 is provided with a cover projection 31 extending downward over substantially the entire circumference of the lower end surface 21a of the skirt wall 21 so as to be spaced from the cylindrical side wall 3 of the cap body 1. It is. That is, by providing such a cover projection 31, there is an advantage that the scattering of the liquid is more reliably prevented, and the gap between the upper lid 2 and the cap body 1 is not recognized from the outside.
Of course, such a cover projection 31 may be provided at least on a half-periphery portion on the opposite side to the hinge connection portion 1a, and need not necessarily be provided over the entire circumference.
[0029]
In the container lid shown in FIG. 7, a cutout portion 32 is formed from the peripheral edge portion 4 a of the ceiling wall 4 to the cylindrical side wall 3 over the entire periphery except the hinge connection portion 1 a. If such a notch 32 is formed, the liquid adhering to the cap body 1 falls through the notch 32, so that the discharged liquid can effectively adhere to the cap body 1 and remain. Therefore, splashing of the liquid when the lid is closed can be more reliably prevented.
[0030]
【The invention's effect】
According to the present invention, the contact and engagement between the skirt wall and the cap body in a state where the upper lid is closed are performed by the circumferential recess provided on the inner surface of the skirt wall, and at least half of the circumference opposite to the hinge connection portion. Since the lower end surface of the skirt wall of the upper lid is provided so as not to be in contact with the cap body over the portion, the upper lid is held in a state in which the liquid is dripping from around the circumferential protrusion serving as a guide for liquid pouring out. Even if it is closed, splashing of the liquid from the engaging portion is blocked by the inner surface of the skirt wall, and splashing of the liquid adhering to the periphery of the ceiling wall of the cap body does not occur.
