Description

TECHNICAL FIELD The present invention relates to a cap attached to a container for holding a liquid such as mayonnaise.

Conventionally, this type of cap is attached to a container 102 containing mayonnaise 101, as shown in FIGS. 16 to 18, for example. The cap 103 includes a cap body 104 that can be attached to the mouth of the container 102, a convex portion 105 provided on the cap body 104, a plurality of pouring holes 106 formed in the convex portion 105, and a pouring hole 106. It has a lid 107 for opening and closing.

A lid 107 is provided on the cap body 104 via a hinge 108 so as to be openable and closable. The convex portion 105 is a cylindrical member and has a circular shape when viewed from the axial direction of the cap body 104 . A pouring chamber 109 communicating with the inside of the container 102 is formed inside the convex portion 105 . Also, the pouring holes 106 are communicated with the pouring chambers 109, and three of them are arranged in a straight line.

According to this, as shown in FIG. 18, the lid 107 is opened, the container 102 is held by hand, the cap 103 is directed downward, and the mayonnaise 101 in the container 102 is poured into the pouring chamber by gripping the container 102 and squeezing it. 109 and is poured out from each pouring hole 106 to the outside.

Incidentally, such a cap as described above is described in Patent Document 1 below, for example.

Utility Model Registration No. 3189876

However, in the conventional method described above, when the mayonnaise 101 is being poured out of the pouring hole 106, the hinge 108 is usually turned upward. At this time, the mayonnaise 101 in the pouring chamber 109 becomes difficult to flow in the space 111 on the hinge mounting side A and tends to stay in the space 111 on the hinge mounting side A of the pouring chamber 109 . This is because the projection 105 has a circular shape when viewed from the axial direction of the cap body 104 .

Further, as shown in FIG. 18, when the container 102 is gripped and the mayonnaise 101 is squeezed out from the pouring hole 106, the liquid pressure of the mayonnaise 101 fluctuates in the pouring chamber 109 inside the projection 105, causing the pouring hole 106 to move. There is a problem that the mayonnaise 101 that is squeezed out from the container does not form a straight line and tends to meander.

The present invention provides a cap capable of reducing the amount of liquid that stays in the space on the hinge attachment side of the pouring chamber in the pouring nozzle when pouring the liquid from the container through the pouring hole. intended to provide

The lid is provided on the cap body via a hinge,
The pouring nozzle has an upwardly protruding seat at the tip,
A pouring chamber communicating with the inside of the container is formed inside the pouring nozzle,
The pouring hole has a cross shape, is formed in the seat of the pouring nozzle and communicates with the pouring chamber,
When viewed from the axial direction of the cap body, the pouring nozzle has a semi-circular or C-shaped shape in which the hinge mounting side is omitted and the opposite side bulges in an arc shape ,
There are no recesses or steps on the upper end surface from the periphery of the seat to the pouring hole .

According to this method, the lid is opened, the container is held with the hand, the cap is directed downward, the container is gripped and squeezed, and the liquid in the container is discharged from each pouring hole through the pouring chamber in the pouring nozzle. It is poured out to the outside. At this time, the hinge is usually directed upward.

When viewed from the axial direction of the cap body, the pouring nozzle does not have a circular shape, but has a semicircular shape or a C shape in which the hinge mounting side is cut off and the opposite side bulges in an arc shape. For this reason, the space on the hinge mounting side of the pouring chamber in the pouring nozzle becomes smaller, and when the liquid in the container is poured out from the pouring hole with the hinge facing upward, the hinge-mounting side of the pouring chamber becomes smaller. The amount of liquid staying in the space is reduced.

Further, when the container is gripped to squeeze out the liquid in the container from the pouring hole, the liquid pressure of the liquid in the pouring chamber in the pouring nozzle is less likely to fluctuate, thereby squeezing from each pouring hole. The discharged liquid material is not easily meandered and is poured in a straight line.
In addition, since the spout hole is cross-shaped, squeeze the container with your hand and pour out the liquid inside the container through the spout hole. is cut near the base of the spout hole. As a result, it is possible to reduce the amount of liquid adhering to the periphery of the pouring hole.

Assuming the line L2, the intersection of the first center line L1 and the second center line L2 coincides with the axis 19 of the cap main body 11 .

The pouring nozzle 12 has a peripheral wall portion 20 rising upward and outward from the top plate portion 17, and an end plate portion 21 provided at the tip of the peripheral wall portion 20. As shown in FIG. When viewed from the axial direction, the hinge mounting side A is omitted and the opposite side B is formed in a semicircular shape.

The peripheral wall portion 20 has a flat side wall 20a facing the hinge mounting side A and perpendicular to the first center line L1, and a semicircular side wall 20b facing the opposite side B of the hinge mounting side A. . The end plate portion 21 has a plurality of circular seats 24a, 24b, and 24c projecting upward.

A pouring chamber 23 communicating with the inside of the container 1 is formed inside the pouring nozzle 12 . The pouring chamber 23 is a space surrounded by the peripheral wall portion 20 and the end plate portion 21 , and the cross-sectional area of the pouring chamber 23 (that is, the area of the cross section perpendicular to the axis 19 ) is the same as the mouth portion 3 of the container 1 . half or about half the cross-sectional area of the inner diameter of Further, as shown in FIG. 5 , an arcuate curved surface 22 is formed along the entire circumference at the corner portion between the peripheral wall portion 20 and the end plate portion 21 in the pouring chamber 23 .

The operation of the above configuration will be described below.

As shown in FIG. 8, the lid 14 is opened, the container 1 is held by hand, the cap 10 is turned obliquely downward, and the mayonnaise 2 in the container 1 is poured out through the pouring chamber 23 by squeezing the container 1. It is discharged to the outside through the discharge holes 13a, 13b and 13c. At this time, the hinge 15 is normally directed upward.

As shown in FIG. 3, the pouring nozzle 12 does not have a circular shape but a semicircular shape when viewed from the axial direction of the cap body 11 . As a result, the space 36 on the hinge mounting side A of the pouring chamber 23 becomes smaller, and as shown in FIG. The amount of the mayonnaise 2 remaining in the space 36 on the hinge mounting side A of the pouring chamber 23 is reduced.

Further, the mayonnaise 2 in the pouring chamber 23 is smoothly turned by the curved surface 22 (see FIG. 5) at the corner portion between the peripheral wall portion 20 and the end plate portion 21, and flows into the respective pouring holes 13a, 13b, and 13c. . As a result, the amount of mayonnaise 2 remaining in the extraction chamber 23 is further reduced.

Further, when the mayonnaise 2 is squeezed out from the pouring holes 13a, 13b, 13c by gripping the container 1, the liquid pressure of the mayonnaise 2 is less likely to fluctuate in the pouring chamber 23, and as a result, the pouring holes 13a, 13b , 13c is poured out in a straight line without meandering.

Although the reason why the mayonnaise 2 is squeezed out from the pouring holes 13a, 13b, 13c in a straight line is unknown, the space on the hinge mounting side A of the pouring chamber 23 is not clear. As the amount of mayonnaise 2 staying in 36 is reduced, the air mixed in mayonnaise 2 in container 1 is less likely to stay in space 36 on hinge mounting side A of pouring chamber 23, and the pouring chamber Since the amount of compressed air remaining in 23 is reduced, the fluid pressure of mayonnaise 2 is less likely to fluctuate in pouring chamber 23, thereby stabilizing the fluid pressure of mayonnaise 2 in pouring chamber 23. It is presumed that the mayonnaise 2 squeezed out from the pouring holes 13a, 13b, 13c is poured out in a straight line.

Moreover, since the pouring holes 13a, 13b, and 13c are cross-shaped holes, the mayonnaise 2 in the container 1 can be poured out from the pouring holes 13a, 13b, and 13c by squeezing the container 1 with force. After that, the mayonnaise 2 is cut near the roots of the pouring holes 13a, 13b, 13c when the hand is relaxed. As a result, the mayonnaise 2 can be drained well, and the amount of the mayonnaise 2 adhering around the pouring holes 13a, 13b, 13c can be reduced.
