Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid pouring cap, and more particularly to a liquid pouring cap suitable for mounting on a container containing soy sauce for use.

[0002]

2. Description of the Related Art As disclosed in, for example, Japanese Utility Model Laid-Open No. 4-74649, a peripheral wall for fitting an outer surface of a container body mouth neck is hung from an outer peripheral portion of a lower surface of a top plate, and in the fitted state of the peripheral wall, a container body mouth neck portion is provided. The top plate portion above the mouth portion of the container body formed by the upper end is formed in the concave portion of the lower surface opening, and nozzle holes are bored from both front and rear portions of the upper end of the inner peripheral wall forming the concave portion to both front and rear portions of the outer peripheral wall surface of the top plate. Caps are commonly used.

[0003]

The conventional cap described above may have a disadvantage that liquid leaks from the nozzle hole after use and stains the outer surface of the peripheral wall of the cap and the outer surface of the container body. As a cause of this, it is considered that the nozzle holes are poorly drained, and a small amount of liquid remains in the nozzle holes.

In order to solve such a drawback, a groove having a narrow width is formed along the longitudinal direction on the upper surface of the lower wall of the nozzle so that the liquid remaining in the nozzle can be removed by utilizing the capillary phenomenon. Some have been configured to return to. Although the above-mentioned drawbacks are considerably eliminated by the formation of this groove, there are still some insufficient portions.

Therefore, as one of the objects of the present invention, there is provided a liquid pouring cap which can more effectively eliminate the stain on the outer surface of the cap and the outer surface of the container body due to the leakage of the liquid from the tip of the nozzle hole as compared with the conventional product. It is a proposal.

Further, the conventional cap of this kind has a disadvantage that the liquid is spouted in an unexpected direction when the liquid is poured out when the amount of the liquid contained in the container is reduced.

That is, when the remaining amount of the stored liquid becomes small, the flow velocity when the container is tilted for pouring increases, and as a result, the liquid spouts faster and it is difficult to pour the liquid to the target site. Become.

Therefore, one of the objects of the present invention is, in addition to the above objects, to propose an excellent liquid pouring cap in which liquid does not unexpectedly splash.

[0009]

In order to solve the above-mentioned problems, the cap according to the first aspect of the present invention provides a liquid on the upper surface of the mouth / neck 3 from the upper edge of the peripheral wall 4 fitted to the mouth / neck of the container body 3 via a packing. A flange 5 for closely contacting the lower surface is extended, a lower peripheral portion is integrally connected to an inner peripheral edge of the flange, and a top wall 7 is extended from an upper end of a pouring tube 6 that is erected upward. It is an integrally molded product made of synthetic resin in which a base end is opened in each of the front and rear parts and a pouring nozzle 8 is projected in the front and rear direction. 8a and an eaves portion 8b projecting from the upper part of the front surface, and each of them is formed so as to project outward and obliquely upward, and the residual liquid is spread over the upper surface of the lower wall portion of each of the short tubular portions 8a and the inner surface of the pouring cylinder. The liquid pouring cap is characterized by being formed with a narrow guide groove (10) for guiding.

In the cap according to the second aspect of the present invention, both side edges are integrally connected to the base end opening of each nozzle and the portion of the spouting cylinder 6 on both sides of each guide groove 10, and the upper end surface is on the lower surface of the top wall 7. The liquid pouring cap according to claim 1, further comprising a coating wall 11 which is integrally connected to cover the opening and the guide groove so that the liquid can be introduced from below.

[0011]

When the container is tilted from the state shown in FIG. 1, the liquid is poured out from the pouring nozzle 8. At this time, the liquid is first poured so as to fill the entire nozzle hole, but it reaches the tip of the nozzle eaves part.
Since it is poured along the lower surface of 8b, the cross section of the effluent becomes smaller.

When the container body is returned to the upright position after the liquid has been poured out, the liquid in the nozzle 8 is returned to the container body. At this time, as described above, since the poured liquid has a small vertical cross-sectional area, The amount of liquid existing in the nozzle portion at the time of pouring is smaller than that of a nozzle of the same length, and therefore the liquid in the nozzle is returned to the container body more quickly (that is, the liquid runs out better) and the nozzle Since the inner and lower surfaces are made shorter than the entire length of the nozzle, the amount of liquid remaining in the nozzle is reduced.

Further, even if there is residual liquid, it is guided into the guide groove 10 by a capillary phenomenon and drops into the container body by its own weight from the lower end opening of the groove 10.

Further, the covering wall 11 as in the container according to the second aspect of the invention.
In the case of the one provided with, even if the residual liquid remaining is reduced, the flow velocity of the pouring liquid is decelerated by this coating wall, and the careless liquid splash can be prevented.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show one embodiment of the present invention, in which 1 denotes a liquid pouring cap. The cap 1
Is an integrally molded product of synthetic resin, and is used by being attached to a container body 2 in which a liquid such as soy sauce is stored.

The container body 2 is made of glass, synthetic resin or the like (in particular, when the storage liquid is soy sauce, it is often made of glass). A cervical part 3 is erected and a thread is provided around the outer circumference of the mouth and neck part.

The cap 1 has a flange 5 extending inward from the upper edge of the peripheral wall 4, and a pouring tube 6 in which a lower outer peripheral portion is integrally connected to the inner peripheral edge of the flange 5 is erected upward, and further A top wall 7 extends from the upper edge of the cylinder 6. Also,
A base end is opened at each of the front and rear portions of the pouring tube 6, and a pouring nozzle 8 is provided so as to project in the front-back direction.

In the present embodiment, there is provided a cylindrical peripheral wall 4 having a thread on its inner surface, and the peripheral wall 4 is attached to the outer periphery of the container neck 3 so that the threads can be detachably mounted. ing. At this time, the packing 9 is sandwiched between the lower surface of the flange 5 and the upper surface of the neck 3 of the container body to prevent the liquid from leaking from this portion. It is configured to project with a small projecting width, and the outer surface of the portion of the spouting cylinder 6 below the flange 5 and the inner surface of the mouth / neck portion are positioned with a small gap therebetween.

Each of the nozzles 8 is composed of a short tubular portion 8a at the base end and an eaves portion 8b integrally provided on the front upper portion of the short tubular portion 8a. ing.

In the present embodiment, the outer periphery is rectangular in a front view, and the short cylindrical portion 8a is provided with a circular nozzle hole in the center in the central portion.
And the eaves portion 8b that is integrally projected from the front half of the front surface of the short tubular portion 8a, and the lower sides of the side wall portions that extend vertically from both sides of the top plate portion are inclined and raised as it goes forward, and each pouring nozzle 8 is configured. are doing.

A narrow guide groove 10 for guiding the residual liquid extends over the upper surface of the lower wall portion of the short cylinder portion 8a of each nozzle and the inner surface of the spout cylinder 6.
Has been drilled.

The guide groove 10 is formed by vertically cutting the center of the upper surface of the lower wall of the short cylinder 8a in the front-rear direction, and vertically cutting the inner surface of the pouring cylinder 6 below the center of the nozzle base end opening. In addition, the portion projecting downward of the flange 5 is formed in the shape of a cut groove that penetrates the inside and outside of the dispensing cylinder. Therefore, even if the liquid remains between the outer surface of the pouring cylinder 6 and the inner surface of the container mouth / neck portion 3 and the inner surface of the packing 9 after the liquid is poured out, the liquid is introduced into the guide groove 10 through a small gap, and then downward. It is configured so that it can be dropped.

FIGS. 3 and 4 show another embodiment of the present invention. In this embodiment, both side edges are integrally formed with the outlet tube 6 on both sides of each nozzle base end opening and each guide groove 10. And the upper end surface is integrally connected to the lower surface of the top wall 7 to provide a pair of coating walls 11 that cover the opening and the guide groove so that liquid can be introduced from below.

[0026]

As described above, according to the cap of the present invention, each nozzle is composed of the short tubular portion at the base end and the eave portion integrally projecting from the front upper portion of the short tubular portion, and each nozzle is slanted. Since it is formed so as to project upward, the amount of liquid existing in the nozzle portion at the time of pouring is smaller than that of a cylindrical nozzle of the same length. While being returned to the body (that is, liquid is well drained), the area of the lower surface inside the nozzle is small, and the amount of the remaining adhered inside the nozzle is smaller. In addition, even if there is liquid remaining in the nozzle, the liquid is sequentially guided into the container body because the nozzle is formed to project obliquely upward and the narrow guide groove exists. Therefore, it is possible to eliminate the inconvenience that the liquid adheres to the outer surface of the cap or the outer surface of the container body and becomes dirty.

In addition to the above effects, in the case where the cover plate is provided as in the second aspect of the present invention, in addition to the above effect, even when the stored liquid becomes small, the liquid may inadvertently spout from the nozzle hole. It's easy to use.
