Description

[Detailed description of the invention] This invention relates to the structure of a pouring outlet in a liquid container such as a thermos.

Conventionally, in containers such as magic bottles, a shoulder body is placed on the upper end of the body, and a shoulder cover is placed on the shoulder body, and the shoulder body and shoulder cover form a cylindrical container on the side. An outlet was formed, and a flap was swingably supported at the tip of the spout to prevent dust and insects such as cockroaches from entering the spout. FIG. 8 shows the structure of this spout 1. The spout portion of the shoulder body 2 has a substantially U-shaped cross section, and a stopper 4 is provided protruding from the upper surface of the front end of the bottom surface 3, and a recessed portion 6 is formed on the inner surface of the upper edge of the front end of the side walls 5. has been done. Further, a projecting edge 8 is formed on the lower side surface of the shoulder cover 7, and a recessed portion 9 is also formed at the front end of the projecting edge 8. When the shoulder cover 7 is placed on the shoulder body 2, a cylindrical spout 1 is formed, and a box-shaped recess is formed on the upper inner surface of the front end side wall of the spout 1 by the recess 6 and the recess 9. 10 is formed.

The flap 11 has a flat plate shape that approximately matches the cross-sectional shape of the spout 1, and has protrusions projecting laterally at the upper ends of both side edges, and the protrusions fit into the recess 10 so as to be able to swing freely. are combined.

By the way, in this type of container, in order to attach the flap 11, as shown in FIG.
It was essential that the spout 1 be composed of two parts: a shoulder body 2 and a shoulder cover 7. If the shoulder body 2 and the shoulder cover 7 could be constructed as one piece, the structure would be very simple and the design would be neat and clean. Since it was necessary to hold the shoulder cover between the shoulder cover 7 and the shoulder cover 7, it was not possible to integrate the two. Furthermore, since the two are separate bodies, a gap is likely to be formed between them due to distortion during molding, and the flap 11 may sometimes fall off from this gap.

The present invention integrates a part corresponding to the conventional shoulder body 2 and a part corresponding to the shoulder cover 7 in this type of container, and also includes a flap 11 at the tip of the spout.
The purpose of this invention is to provide a structure for a spout of a container to which a spout can be attached.

FIG. 1 is a vertical cross-sectional view of the upper center of the magic bottle to which the present invention is applied. A middle bottle 13 is housed in the body 12, and a shoulder body 14 is placed on top of the middle bottle 13.
The shoulder body 14 corresponds to the above-mentioned conventional example in which the shoulder body 2 and the shoulder cover 7 are integrated, and a short cylindrical portion 16 with a female thread formed on the inner surface is provided at the center of the bottom surface 15 downward. The injection port is formed in a protruding manner. A short cylindrical portion 17 extending downward is provided on the outer peripheral edge of the bottom surface 15, and is fitted onto the upper end of the body 12. Further, a substantially truncated cone-shaped outer shell 18 is provided upwardly. A cylindrical spout 1 is provided in a part of the outer shell 18 to protrude laterally, and a flap 11 is provided at the tip of the spout 1.
is attached so that it can swing freely. Reference numeral 19 denotes a plug that is removably screwed onto the female thread.

2 to 4 show the structure of the tip portion of the spout 1. FIG. The spout 1 has a substantially U-shape from a bottom portion 20 to a side wall 21, and an upper plate 22 is integrally provided on the side wall, so that the spout 1 has a cylindrical shape as a whole. The upper plate 2 is attached to the tip of the upper plate 22.
An elongated hole 23 is formed over the entire width of the side wall 2, and a recess 24 continuous to the elongated hole 23 is formed at the upper end of both side walls 21. The recess 24 passes through the side wall 21 , and the lower part of the recess 24 extends slightly rearward than the elongated hole, and a step 25 is formed between it and the rear edge of the elongated hole 23 .

The flap 11 has a shape that approximately matches the cross-sectional shape of the inner surface of the spout 1, and a projection 26 that projects laterally is formed at the upper end of both side edges.

The flap 11 is inserted into the spout 1 through the elongated hole 23, and the protrusion 26 is fitted into the recess 24, so that it can swing freely around the protrusion 26. The flap 11 is attached so that its lower part is inclined slightly forward, and its lower edge is in contact with the inner surface of the bottom part 20, so that it can swing only in the forward direction.

FIGS. 5 to 7 show another embodiment in which the recess 24 does not penetrate the side wall 21 but is recessed into the upper end of the inner surface of the side wall 21. A stopper 27 is provided on the inner surface of the bottom surface 20 to prevent the flap 11 from swinging backward.

In the present invention, the flap 11 normally swings downward to prevent dust and insects from entering from the tip of the spout 1, and when the container is tilted to pour out the content, the flap 11 swings downward. As shown by the chain line in Figure 5, it swings forward to allow the liquid content to flow out. In the present invention, an elongated hole 23 is formed on the top surface of the distal end of the spout 1, the flap 11 is inserted through the elongated hole 23, and the flap 11 is inserted into the recess 24 formed in the side wall 21.
Since the spout 1 is supported, the flap 11 can be attached even if the spout 1 is integrally formed, and the structure of the container becomes simple, and it is easy to manufacture and can be provided at low cost. It is also possible to make it clear and excellent. Also, since the stepped portion 25 is formed in the recessed portion 24,
The flap 11 will not fall out of the elongated hole 23. That is, when a forward force is applied to the flap 11, the flap 11 swings forward so that it does not fall off, and when a rearward force is applied to the flap 11, the upper edge of the protrusion 26 moves into the recess. The protrusion 26 moves upward along the rear edge of the elongated hole 24, but at this time the protrusion 26 engages with the step 25 and the elongated hole 2
This prevents it from falling off from 3.

In the present invention, the recess 24 may pass through the side wall 21 as in the previous embodiment, or may not pass through the side wall 21 as in the later embodiment. If the recess is made to penetrate, the width of the recess is large and the flap 11 can be supported more stably.
The outer surface of the side wall is smooth and has an excellent design. Further, as a means for preventing rearward swinging of the flap 11, as shown in FIG.
0, or a stopper 27 may be provided as shown in FIG.
