Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing cap, and more particularly, to a dispensing cap which is attached to a container having a squeezable body to discharge a liquid content.

[0002]

[Prior art]

[Problem to be solved by the invention]
A cap body having a top wall extending from the upper edge of the peripheral wall fitted to the outer periphery of the mouth and neck of the container body, the top wall closing the upper opening of the mouth and neck, and having a pouring hole formed at the center of the top wall, 2. Description of the Related Art There is known a configuration in which a liquid in a container is discharged from the discharge hole by squeezing a body portion of the container.

[0003] However, in these caps, even when the pressing force of the body of the container is controlled, the stored liquid is always discharged only in a substantially rod shape.

According to the present invention, a rod-shaped dispensing form or a wide range can be dispensed by controlling the squeezing of the body of the container and changing the liquid pressure, instead of the conventional one-sided dispensing like a container of this kind. The present invention proposes an excellent dispensing cap capable of selecting a shower-like dispensing mode.

[0005]

In order to solve the above problems, the container according to the present invention integrally connects the outer surface of the outer cylinder portion 10 to the inner peripheral edge of the inward flange-like top wall 9 extending from the upper end edge of the peripheral wall 8, and A flange 11 extends inward from the lower edge of the outer cylinder 10, and an inner cylinder 12 having a lid is provided upright in a double cylindrical shape from the inner periphery of the flange 11, and an annular recess 13 is formed on the outer periphery thereof. And a base fitted to the outer periphery of the inner cylinder 12
A tapered valve plate 23 extending obliquely upward from 22 is extended, and the outer periphery of the valve plate 23 is brought into liquid-tight contact with the inner surface of the outer cylinder 10 to open the annular concave opening upward. And a discharge hole 15 formed in the top wall 14 of the inner cylinder portion 12 and a communication hole 16 formed in the flash 11.

[0006]

When the container body 6 is squeezed lightly, the liquid from the communication hole 16 through the annular recess 13 to the valve plate 23 is discharged because the spout is closed by the elastic force of the valve plate 23. Instead, only the liquid that passes through the inside of the inner cylindrical portion 12 and reaches the pouring hole 15 is poured out to form a rod-like liquid pouring form. On the other hand, when the squeezing of the body 6 is increased, the pressure of the liquid introduced into the annular concave portion 13 increases and the valve plate 23 is pushed out to be poured out, so that a wide shower-like liquid discharging form is obtained.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

[0008] The dispensing cap 1 of the present invention is used by being attached to the container 2, and comprises a cap body 3, a lid 4, and a valve 5.

The container body 2 is made of a synthetic resin in which the mouth and neck 7 is erected from the upper end of the body 6 which can be squeezed, and the mouth and neck 7 is inclined slightly forward with respect to the body 6 so that the liquid can be easily poured out. doing.

The cap body 3 and the lid 4 are formed as an integrally molded product of a synthetic resin. The cap body 3 has an inward flange shape from an upper edge of a peripheral wall 8 screwed to the outer periphery of the container body neck 7. A top wall 9 is extended, and an outer cylindrical portion 10 having an upper peripheral surface integrally connected to an inner peripheral edge of the top wall 9 and a lower end hanging down in the mouth and neck portion 7 is extended. The outer circumference is fitted to the upper end of the inner circumference of the mouth and neck 7 in a liquid-tight manner. Also, the outer cylinder 10
An inward flange 11 extends from the lower edge, and the flange 11
An inner cylindrical portion 12 having a lid is erected in a double cylindrical shape from an inner peripheral edge, and an annular concave portion 13 is formed on an outer periphery thereof. Further, a pouring hole 15 is formed in the center of the top wall 14 of the inner cylindrical portion 12, and a communicating hole 16 is formed in the flange 11 connecting the inner and outer cylindrical portions 12, 10 to communicate vertically.

The lid 4 is connected to the rear portion of the cap body 3 via a known three-point hinge mechanism so that the rear portion can be elastically inverted, and is fitted in an upwardly open step 17 provided on the outer periphery of the top wall 9 of the cap body so as to be openable and closable. A top wall 19 that closes the upper surface of the cap body extends from the upper edge of the peripheral wall 18 thus formed. Further, a fitting tube 20 which is detachably fitted to the outer peripheral upper end of the inner cylindrical portion 12 of the cap body 3 from the center of the back surface of the top wall 19 to close the pouring hole 15 in a liquid-tight manner,
Further, a tapered cylinder 21 whose outer surface forms a predetermined inclined surface on the outer peripheral portion thereof.
Are respectively erected.

The valve body 5 is made of a flexible and resilient material such as an elastomer.
It is housed and mounted in 13. Further, a tapered valve plate portion 23 extending obliquely upward from the upper end edge of the cylindrical base portion 22 fitted and fixed to the outer periphery lower portion of the inner cylinder portion 12 is extended, and the upper end edge portion of the outer surface of the valve plate portion 23 is fixed to the outer cylinder. Upwardly inclined stepped portion 24 provided in the upper part of the inner periphery of portion 10
By closing the opening of the annular recess 13 so as to be able to be opened upward by making a liquid-tight contact with the valve plate 23, a unidirectional flow of the liquid can be made upward from below the valve plate portion 23. Also, valve plate 23
The upper end of the inner surface of the lid 4 is pressed by the inclined surface of the tapered cylinder 21 of the lid 4 to prevent liquid leakage from around the valve plate 23 when the lid is closed.

The present invention is not limited to the embodiment described above.
The material, structure, shape and the like can be appropriately changed within the scope of changing the gist of the present invention.

[0014]

[Effects of the Invention] As described above, the container of the present invention has the above-described configuration, so that if the body of the mounted container body is squeezed weakly, it takes a rod-like liquid pouring form, and the body is strongly squeezed. If this is done, the liquid can be poured out from around the valve plate, and a shower-like liquid pouring form can be adopted, which is extremely convenient in use.

Further, since the structure is simple, there is an advantage that it can be manufactured at low cost.
