However, in the above-mentioned container, when the container is poured, the container is tilted to allow the content liquid to flow out. However, since the pouring cylinder is formed on the top wall, Considering the inclination angle of the container, it was necessary to be careful in adjusting the outflow amount, and in particular, a large amount of the content liquid was allowed to flow out at the beginning of the pouring and scattered around. The liquid flowing out from the pouring hole sometimes flowed in an unexpected direction because there was no guide. In order to drain the remaining liquid, the container is inverted, but it was not easy to drain all the liquid. When the volume of the container is large and the content liquid is large, it is difficult to gradually incline the angle of the container, which causes a problem that the outflow amount cannot be made constant. Furthermore, the flow is blocked by the top wall, which promotes fluctuations in the flow rate, which makes it unsuitable for large containers.

The present invention has a technical object to solve the above-mentioned problems, and forms a spout cylinder extending upward in a manner continuous with the body peripheral wall on the upper part of the container body, and the upper wall of the spout cylinder. An object of the present invention is to provide a large-sized liquid container having a lid that can be opened and closed.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described.
This will be described with reference to the drawings. As shown in FIG. 1, the container body of the present invention comprises a container body 1, a top wall 2, a spout cylinder 3 and a reinforcing rib 4 provided on the upper part of the container body, and they are integrally made of synthetic resin. It is molded. The container body 1 is composed of a cylindrical lower peripheral wall 1a, a conical intermediate peripheral wall 1b, and a trumpet-shaped upper peripheral wall 1c that continuously extends upward from the peripheral wall, and its upper end is a top wall 2. Has become.

As shown in FIGS. 2 to 4, on the side of the upper peripheral wall 1c, there is an angular pour consisting of an arcuate peripheral wall 3a extending from the intermediate peripheral wall 1b and a side wall 3b extending outward from the upper peripheral wall 1c and facing each other. An outlet cylinder 3 is formed. The top wall 5 of the spouting cylinder is provided continuously with the top wall 2 and is inclined downward, and a thin hinge portion 6 is provided at the boundary with the top wall 2. On the upper surface of the upper wall 5, breaking grooves 7a, 7b are engraved in a substantially U shape along the upper side of the inner surface of the circular arc peripheral wall 3a and the side wall 3b, cut when the container is opened, and the lid 9 of the pouring hole 8 is cut. To form. At the end of the lid body 9 on the side of the circular arc peripheral wall 3a, a knob piece 10 is erected so that its upper end is located below the top wall 2.

As shown in FIG. 1, the reinforcing rib 4 is formed on the side of the upper peripheral wall 1c on the opposite side of the pouring cylinder, extends upward continuously from the intermediate peripheral wall 1b, and the upper end thereof is the top wall 2. Is flush with the top surface of. On the upper surface of the container top wall 2, the locking recess 1
1 is provided so that the tab 10 of the lid 9 that is opened when the container is used is locked.

A stacking rib 12 is provided at the upper end of the lower peripheral wall 1a so that the formed containers can be stacked and transported. A flange 13 is provided at the lower end of the container body, and a thin bottom plate 14 is joined to the lower surface of the flange 13. The bottom plate 14 is fused after filling with the content liquid,
It is designed to seal the content liquid.

Next, the function and effect of the above configuration will be described. As shown in FIG. 5, when the liquid filling container is opened, if the gripping piece 10 is grasped and pulled upward, the pouring cylinder upper wall 5
The fractured grooves 7 (a, b) of the
Is bent to form the lid 9, and the pouring hole 8 is formed. At the time of pouring, when the knob 10 is locked in the locking recess 11 of the top wall 2 and the container is inclined while holding the upper peripheral wall 1c together with the reinforcing rib 4, the circular arc peripheral wall 3a of the pouring cylinder becomes the body part. Since it is formed continuously on the intermediate wall 1b of
The content liquid flows and flows out smoothly according to the inclination, and the content liquid can be reliably poured out to the end.

When the pouring hole 8 is to be closed while the content liquid remains in the middle of use of the container, when the lid 9 is closed by holding the knob 10, the end of the container engages with the circular arc peripheral wall. Therefore, the pouring hole 8 is closed to prevent dust from entering.

[0012]

Since the present invention is configured as described above, it has the following effects. Since the circular arc peripheral wall of the pouring cylinder is continuous with the circumferential intermediate peripheral wall of the container body, the flow of the content liquid did not fluctuate and the outflow became smooth. Therefore, it becomes possible to easily incline the inclination angle of the container to make the outflow amount constant, and it is easy to increase the size of the container. In addition, the content liquid can be reliably poured out to the end without the container being inverted.

The lid is opened and closed centering on the hinge portion, and when pouring, the picking piece engages with the engaging concave portion of the top wall and does not get in the way, and the pouring hole can be closed during pouring. It is possible to prevent dust in the air from entering. Since the tab is formed inside the container body and its upper end is lower than the top wall, the container bodies can be stacked and transported,
Even during transportation of the liquid-filled container, the liquid-filled container does not come into contact with other containers to be deformed, and an accident due to cutting of the breakage portion can be prevented.
