Abstract

PURPOSE: To present a structure for a cap for which a lid is connected in an openable and shuttable state to a cap main body so that a liquid stuck to the reverse side of the lid can be prevented from dropping and staining the cap main body when the liquid is poured out after being stirred up with the container shaken. CONSTITUTION: The structure is so constructed that a device in a special structure for preventing liquid from dropping is provided at the reverse side of the top plate 16 of a lid. The device 4 for preventing the liquid from dropping is constructed of a fitting drum 21 pressed liquid-tightly at its inwardly warped lower edge against a trumpet-shaped front 7a of a spouting cylinder 7 erected on a cap main body 2 and a plurality of circular-arc-like walls 22, each provided in dangling at the inside of the fitting drum in a shape protruding in a warped circular-arc-shape toward the rear and warping at its lower edge toward the diametrally contracting direction.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to liquid dispensing caps.

[0002]

2. Description of the Related Art As a liquid pouring cap, for example, a top wall is extended from the upper edge of a peripheral wall fitted to the outer periphery of the neck of a container body, and a pouring cylinder is erected from the center of the top wall. From a cap body provided with a pulling lid with a pull ring on the top wall in the outlet cylinder so as to be able to be cut, and a lid body in which a rear lower end is rotatably connected to a rear upper end of the main body so that the upper face of the main body can be opened and closed. Is known. In general, the upper end of the spouting tube of these caps expands like a trumpet tip, and the lower end edge of an annular projection extending from the back surface of the lid is pressed against the inner surface of the expanding part to provide sealing performance. I am letting you.

In use, the pull ring is pulled up to cut and remove the lid, and the liquid is poured out from the pouring port opened therethrough through the pouring tube.

[0004]

As a liquid to be stored in a container equipped with this kind of cap, it is preferable to shake the container sufficiently to stir it immediately before use. As such a liquid, for example, a liquid that separates the components when left to stand like a dressing applied to a salad is mentioned.

When the stored liquid is poured out after stirring, the liquid adheres to the back surface of the top wall of the lid inside the annular ridge, and the liquid gets over the annular ridge as the lid rotates when the lid is opened. The liquid is transferred to the back surface of the outer lid top wall, and the liquid is collected in the lower portion (rear portion) inside the peripheral wall. This tendency is particularly remarkable when the lid body is placed in an opened state and the lid body stops in a tilted state. Then, when the lid is closed, the liquid that has accumulated flows down onto the cap body on the outer side of the dispensing cylinder, which causes a problem that the cap body is contaminated with the liquid. There is room for eliminating such inconveniences if the protruding width of the annular projection is made quite large, but this time the entire cap becomes large, which is not preferable in appearance, and the amount of resin used during formation is large. There is also a problem in terms of cost. Even if this is not the case, in this type of cap, since the pouring tube is erected, the height of the lid is relatively high.

Under these circumstances, as a container for storing this kind of liquid, a container equipped with a pouring cap constructed so that a lid is detachably screwed is generally used. For example, a cap main body having a similar structure to the cap main body attached to the container body, a top wall extending from the upper end edge of the peripheral wall having a lower portion screwed to the upper peripheral wall of the main body, and a ring extending vertically from the back surface of the top wall. There is used a lid formed by liquid-tightly pressing the lower end edge of the protrusion against the upper end edge of the spouting cylinder. With such a container, the removed lid can be placed upside down on a desk, etc., so that the adhered liquid does not deviate to one side, and it is extremely unlikely to leak to the outside when reattached. Complete.

On the other hand, the screwing and unthreading operation of the lid is more troublesome than that of simply rotating the lid to open and close it.
The place where the removed lid is placed must be taken into consideration, and there is a risk that the removed lid will be lost.

In view of the above points, the present invention is a cap in which a lid is openably and closably connected to a cap body, and is attached to the back surface of the lid when the container is shaken to stir the stored liquid and then poured out. It is possible to prevent the liquid from dripping and polluting the cap body as much as possible, and there is no need to enlarge the entire cap.
It also proposes an excellent spout cap that does not cause inconveniences such as loss of the lid and storage location.

[0014]

[Function] When the container is shaken and the stored liquid is stirred and mixed and then poured out, the liquid adhered to the lid body 3 due to the presence of the liquid dripping prevention mechanism 4 (4A, 4B, 4C, 4D) is covered with the lid body 3 and the cap. It is prevented that the connecting portion with the main body 2 or its periphery is drooped.

In the embodiment shown in FIGS. 1 to 4, half of the fitting cylinder 21 and each of the arcuate walls 22 face downward and the lower end edge thereof has a reduced diameter when the lid is opened and closed. Because it is curved in the direction, the fitting cylinder 21 and each arcuate wall 22
Prevents it from hanging downwards.

Similarly in the embodiment shown in FIGS. 5 and 6, the latter half of the fitting cylinder 21 and the latter half of the spiral wall 23 prevent the liquid from dripping.

In the embodiment shown in FIGS. 7 to 10, since the liquid adhering to the back surface of the lid top wall 16 is separated into a large number of small chambers 24, the amount of liquid in each small chamber 24 becomes small and the lid is opened and closed. Even if there is an inclination at some time, it cannot drop out of the fitting cylinder 21a.

In the embodiment shown in FIGS. 11 and 12, each arcuate wall 27 separates a small amount of the liquid adhering to the back surface of the lid top wall to prevent the liquid from leaking to the outside of the fitting cylinder 21a and to close it. When the lid is closed, the liquid flows down through the rod-shaped projections 28 into the container body.

In the embodiment shown in FIGS. 13 to 15, the liquid adhering to the back surface of the lid top wall 16 is dispersed in the small chambers defined by the ribs 29, and the liquid in each small chamber is closed when the lid is closed. Collect in the center and flow down into the container body from the central apex of each rib 29.

[0034]

As described above, since the liquid pouring cap of the present invention is provided with the liquid dripping prevention mechanism on the back surface of the top wall of the lid, the liquid on the back surface of the lid top wall adhered by stirring the stored liquid does not cover the lid. It is possible to prevent the inconvenience such as dripping on the connecting portion with the cap body and the cap body around the body when the body is opened and closed.

Moreover, it also has an advantage that such an effect can be exhibited without increasing the size of the entire cap.

Further, since the lid body is integrally connected to the cap body, there is no inconvenience such as the location of the removed lid body or the loss of the lid body.
