Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a spout to be attached to the mouth of a container filled with a liquid for use.

(Prior Art) As a conventional spout, since droplets flow down from its periphery to its outer peripheral wall after use, as shown in FIG.
In order to prevent this, an annular projecting wall 2'is provided on the outer circumference of the pouring inner cylinder 1'with a return groove 4 ', and an inclined edge 3' (baffle plate) is provided inside the upper part of the projecting wall 2 '. There is a protruding wall 2'provided with a return hole 5 '. In this pouring port, the droplets that have flowed down the outer wall surface of the pouring inner cylinder 1'are received in the return groove 4 ', and at the time of pouring out again, the outflow from the return groove 4'to the outside is inclined. 3'is to prevent it. (See Japanese Utility Model Publication No. 43-26078).

(Problems to be solved by the device) However, if the spout shown in FIG. 3 is capped with a cap 6'as shown by the chain line, the filling liquid is returned from the return hole 5'to the return groove 4 when the container is tilted. Since it flows out to the ′ ′, there is a possibility that the fastening screw portion may be wetted, and it is meaningless to provide the inclined edge 3 ′.

Therefore, in the present invention, by providing an annular baffle plate and improving the structure of the spout having a return hole in the pouring inner cylinder and the lid body to be combined with this, even if the container falls, it is obstructed by the content liquid. It is configured so that the area around the board does not get wet.

(Means for Solving the Problem) In order to achieve the above object, the present invention applies an inner peripheral surface to a ring-shaped outer wall that engages with a lid outer wall of a lid and a cylindrical rib inside the lid outer wall. A spout which is joined to the pouring inner cylinder to be contacted at a lower portion with an interval so that an annular return groove is formed, and a plurality of return ports are formed in a lower peripheral wall of the pouring inner cylinder. A plurality of barriers are provided inside the pouring inner cylinder so as to face the plurality of return ports, with a gap provided so that a rib of the lid body can be inserted therein.

Further, it is characterized in that the diameter of the upper portion of the pouring inner cylinder is expanded in a trumpet mouth shape.

(Operation) When the lid is attached to the spout, the lower part of the rib comes into contact with the lower peripheral wall of the pouring inner cylinder, and the peripheral surface of the rib closes the return port. Further, when the content liquid is poured with the lid removed, the content liquid flows along the barrier along the inner peripheral surface of the pouring inner cylinder, so the barrier prevents the content liquid from leaking to the outside from the return port. There is.

Further, since the upper portion of the pouring inner cylinder is shaped like a trumpet, it is easy to guide the content liquid.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing the synthetic resin spout 1 and the lid 20 of the present invention separated from each other. First, the structure of the spout will be described. The spout 1 has a substantially cylindrical shape and is made of a synthetic resin such as polypropylene or polyethylene. The spout 1 has an outlet 2 in its center. Outlet 2 is
In this embodiment, in order to provide a proof property, it is closed by a blocking plate 4 having a handle 3. Blocking plate (removal lid) 4
Is connected to the spout 1 through an annular groove 5, and by pulling up the handle 3, the blocking plate 4 is cut and removed from the portion of the groove 5, and the outlet 2 is opened. An annular outer wall 6 is projectingly provided on the upper portion of the spout 1, and a baffle plate 7 is provided inwardly around the entire upper edge of the annular outer wall 6, and the baffle plate 7 is appropriately spaced. A plurality of slits 8 extending in the radial direction from the edge of the baffle plate 7 to the outer wall 6 are provided.

An annular pouring inner cylinder 10 having a height protruding above the outer wall 6 is provided at intervals so as to form an annular groove 9 inside the outer wall 6. A plurality of liquid return ports 11 penetrating the pouring inner cylinder 10 and communicating with the return groove 9 and the inside of the pouring inner cylinder 10 are provided in the lower portion of the pouring inner cylinder 10.

Further, a plurality of arc-shaped barriers 12 are projected upward inside the pouring inner cylinder 10 and along the inner circumference of the outlet 2, and gaps 13 directed vertically are poured between the barriers 12. It is formed at a position that does not align with the return port 11 of the delivery tube 10.

Next, the lid 20 will be described. The lid 20 is also made of the same synthetic resin as the spout. The lid body 20 includes a top plate 24, a cylindrical rib 21 projecting from the lower surface thereof, and an outer peripheral wall 22 concentrically arranged on the outer periphery of the rib 21. The outer diameter a of the cylindrical rib 21 is substantially equal to the inner diameter of the minimum diameter portion of the pouring inner cylinder 10 of the spout 1, and the inner diameter of the outer peripheral wall 22 is substantially equal to the outer diameter of the outer wall 6 of the spout 1. It is configured. The skirt portion 23 of the lid body 20 is a portion provided as needed.

When the lid 20 is capped on the spout 1 configured as described above,
As shown in FIG. 2, the rib 21 of the lid 20 comes into contact with the inner peripheral surface of the pouring inner cylinder 10 of the spout 1 to close the opening of the return port 11 of the pouring inner cylinder, and the outer circumference. Since the wall 22 engages with the outer wall 6 of the spout 1 via the screw means, the blocking plate 4 is removed and the outflow port 2 is opened. Even if it falls, the liquid in the container does not flow out from the space surrounded by the rib 21 and the top plate 24. Next, when the lid is opened and the content liquid is used, when the container is tilted, the barrier 13 becomes in a state of covering the upper part of the return port 11, so that the return groove 9
It is possible to pour the content liquid only from the pouring inner cylinder without the content liquid wrapping around. In addition, since the return port 11 and the barrier 13 are provided in plural, the container can be poured out in any direction without tilting. After pouring, the container is raised and the residual liquid enters the return groove 9 and is collected inside through the return port 11. The residual liquid slightly left in the return groove 9 is prevented from spilling by the baffle plate 7 when pouring the content liquid next time.

(Advantages of the Invention) Since the present invention is configured as described above, even if the container is tilted with the lid covered with the spout, the return port is blocked by the ribs, so that the leakage of the content liquid When the lid is removed and the liquid content is poured, the liquid content does not flow to the return port due to the barrier, so that the liquid can be poured only from the pouring inner cylinder, and the surrounding area can be kept clean. In addition, the container can be tilted in any direction, and the content liquid can be poured out without scattering and without being contaminated. Moreover, when the container is raised after the pouring, the content liquid attached to the end of the pouring inner cylinder is recovered inside through the return groove. In this way, it is easy to use,
The area around the spout can be kept clean.
