Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a pouring stopper that is attached to the mouth of a container containing various liquid seasonings and the like.

[Technical background of the invention and its problems]

Conventionally, this type of spout faucet has a top lid that is removable from the base lid, which has the disadvantage of the top lid rolling and falling onto the floor, or the top lid being lost. It was hot. In addition, in cases where the top lid and the base lid are connected and formed integrally, when pouring out the liquid in the container, the top lid will tilt toward the pouring hole due to its own weight, etc. However, there were problems such as interfering with pouring work. Furthermore, for example, the opening/closing mechanism of a container bottle described in Japanese Utility Model Publication No. 55-24278 and the cap opening/closing mechanism described in Japanese Utility Model Publication No. 53-28005 can maintain the lid closed state. It had drawbacks such as being unable to maintain the lid open and having an unsightly appearance.

[Purpose of invention]

Therefore, the present invention was devised in order to solve the problems that existed in the past as described above. The top lid can be tilted toward the top to ensure that the top lid remains open so as not to interfere with pouring, and the top lid can also be kept closed. The purpose of this invention is to provide a spout with a good appearance.

[Summary of the idea]

Therefore, in order to achieve the above-mentioned purpose, the present invention
A base lid made of synthetic resin is attached to the mouth of a container containing liquid etc. and is provided with a spout, and an upper lid made of synthetic resin is removably engaged with the upper part of the base lid. The base cover is connected to the side peripheral wall through two band-shaped flexible connecting pieces made of synthetic resin that are arranged in parallel at appropriate intervals on the side peripheral wall. A housing recess is formed by recessing the upper plate slightly to the rear, and a corner formed by the upper edge of the rear wall of the housing groove and the upper plate edge is formed to have a slight roundness, Similarly, the upper lid body is formed with a stop protrusion that is elastically bendable and has a slightly rounded tip, which is formed by extending a part of the side peripheral wall toward the accommodation groove of the base lid body. , when the top lid body is engaged with the base lid body and the spout tap is in the closed state, the stop protrusion is accommodated in the accommodation groove and its back surface is in close contact with the back wall of the groove, and the top lid body and When the base lid is released from the engaged state and the top lid is swung around the flexible connecting piece to open the spout, the stop protrusion slides upward along the inner wall of the groove. Then, the tip portion that passes over the corner formed by the upper edge of the inner wall of the groove and the edge of the upper plate comes into contact with the upper surface of the upper plate of the base cover, and prevents the upper cover from swinging toward the base cover. On the other hand, at the position opposite to where the flexible connecting piece is provided, there is a protrusion on the lower end of the inner peripheral surface of the side peripheral wall of the upper lid body. The gist of the present invention is that a locking body having a concave portion with which the protrusion is removably engaged is provided in a protruding manner on the upper surface of the upper plate of the base cover.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the figure, T indicates a spouting stopper according to the present invention, and this spouting stopper T is a container Y for storing liquid seasonings, etc.
The spout plug 21 is fitted to the mouth of the spout 21
A synthetic resin base body A with a synthetic resin base body A and a synthetic resin top body B that is removably engaged with the upper part of this base body A are connected to the side peripheral wall 2 of the base body A and the top body body at appropriate intervals. They are integrally connected via two synthetic resin elongated band-shaped flexible connecting pieces 20, 20 disposed so as to straddle the side peripheral wall 13 of B, and by bending the flexible connecting piece 20. The upper cover body B is configured to be able to swing relative to the base cover body A around the flexible connecting piece 20.

The base body A includes an upper plate 3 connected to the upper part of a substantially cylindrical side wall 2, and an outer cylinder 1 formed in a substantially cylindrical shape with an open bottom. A housing recess 4 formed by recessing the plate 3 slightly toward the back is formed between two flexible connecting pieces 20, 20. In addition, in the figure, 5 is the back wall of the trench, and 6 is the back wall of the trench 5.
This corner is formed by the upper edge and the edge of the upper plate 3, and the corner 6 here is slightly rounded. Also, 22
is a cut-off piece for opening that closes the spout 21;
The opening cutoff piece 22 is forcibly removed from the spout 21 during use.

The upper lid body B includes a stop protrusion 11 formed by extending downwardly a part of the side peripheral wall 13 of the crown body 10 formed in a substantially cylindrical shape with an open bottom, and two flexible connecting pieces. 20, 20, this stop protrusion 11 is formed to be elastically flexible, and the spout tap T is closed by engaging the top lid body B with the base lid body A. When in the lid state, the stop protrusion 11 is accommodated in the accommodation groove 4, and the back surface of the stop protrusion 11 is brought into close contact with the groove inner wall 5, and furthermore, the upper cover body B and the base cover body A are engaged. When the state is released and the upper lid body B is swung around the flexible connecting piece 20 to open the spout T, the stop protrusion 11 itself bends elastically and its tip When the part slides upward on the groove back wall 5 and overcomes the corner 6, the elastic force is released and the stop protrusion 11 itself returns to its original state, and its tip portion touches the upper surface of the upper plate 3 of the base body A. It is formed so as to be in contact with the top lid body B to prevent the top lid body B from swinging toward the base lid body A side, and to maintain the open state of the spout tap T.

The tip of the stop protrusion 11 is slightly rounded, so that when the stop protrusion 11 bends and climbs over the corner 6, it can do so smoothly.

Further, at a position opposite to where the flexible connecting piece 20 is provided in the spout T, a protrusion 12 is formed at the lower end portion of the inner circumferential surface of the side circumferential wall 13 of the upper lid body B, and this protrusion 1
A locking body 7 having a recess 8 into which the locking body 2 is removably engaged is provided in a protruding manner on the upper surface of the upper plate 3 of the base cover A.

The present invention is constructed as described above, and its use will now be explained.

When the upper lid body B is forcibly pushed up in a direction swinging away from the base lid body A around the flexible connecting piece 20, the flexible connecting piece 20 is elastically bent and the protrusion 1
2 and the recess 8 is released, and the stop protrusion 11 elastically bends while its tip portion slides upward on the inner groove wall 5. When the tip of the stop protrusion 11 gets over the corner 6, the elastic distortion of the stop protrusion 11 itself is released, and
The tip of the stop protrusion 11 comes into contact with the upper surface of the upper plate 3,
The upper lid body B remains open with respect to the base lid body A.

Then, in order to open the spout 21, the cap-opening cut-off piece 22 is pressed so as to be tilted from the side, and the break connecting the lower edge of the cap-opening cut-off piece 22 and the circumferential edge of the spout 21 is broken. The spout 21 is opened by forcibly breaking the membrane and removing the cut-off piece 22 for opening the cap.

Note that even if the entire container Y is tilted and the liquid in the container Y is poured out from the spout 21, the tip of the stop protrusion 11 comes into contact with the upper surface of the upper plate 3 and supports the entire upper lid body B. The stopper T remains open (see Figure 2).

Furthermore, after dispensing the liquid in the container Y, when the top cover B is forcibly swung toward the base cover A, the stop protrusion 11 is elastically bent and its tip portion forms a corner. 6 and slides downward on the groove back wall 5, and the back surface of the stop protrusion 11 comes into close contact with the groove back wall 5, causing elastic distortion of each of the flexible connecting piece 20 and the stop protrusion 11. is released and restored to its original state, and the protrusion 12 and the recess 8 are engaged to bring the spout T into a closed state (see FIG. 3).

[Effect of idea]

Therefore, there is a base cover A made of synthetic resin that is attached to the mouth of a container Y containing a liquid etc. and is provided with a spout 21, and a base cover A made of synthetic resin that is removably engaged with the upper part of the base cover A. The upper lid body B is connected to the respective side peripheral walls 2, 13.
Since the two flexible connecting pieces 20, 20 made of synthetic resin are arranged in parallel at appropriate intervals, the flexible connecting piece 20 serves as the center to connect the top cover B to the base cover A. It can be made swingable, and the spout T can be repeatedly moved from an open state to a closed state or from a closed state to an open state any number of times. Moreover, since the flexible connecting piece 20 is formed into a band shape and is disposed so as to straddle the respective side peripheral walls 2 and 13, the flexible connecting piece 20 does not protrude significantly outward, and the spout T can be formed smartly, and furthermore, the spout T can be formed integrally, making it easy to manufacture.

Further, between the two flexible connecting pieces 20, 20, a housing groove 4 is formed in the base cover A by recessing the side peripheral wall 2 and the top plate 3 slightly to the rear, Similarly, the upper lid body B is formed with an elastically bendable stop protrusion 11 formed by extending a part of the side peripheral wall 13 toward the accommodation groove 4 of the base lid body A. The accommodation groove 4 and the stop protrusion 11 are not noticeable and the appearance is good.

Further, when the top lid body B is engaged with the base lid body A and the spout T is in the closed lid state, the stop protrusion 11 is accommodated in the accommodation groove 4 and is attached to the inner surface of the groove inner wall 5. are in close contact with each other, the engagement state between the upper lid body B and the base lid body A is released, the upper lid body B is swung around the flexible connecting piece 20, and the spout tap T is in the open lid state. 11 is
The tip portion of the groove that slides upwardly over the corner 6 formed by the upper edge of the groove inner wall 5 and the edge of the upper plate 3 comes into contact with the upper surface of the upper plate 3 of the base cover A. The spout tap T
When the spout T is in the closed state, the stop protrusion 11 is properly accommodated in the storage groove 4 without protruding outward, which improves the appearance. In addition, since the inner surface of the stop protrusion 11 comes into close contact with the inner groove wall 5 of the storage groove 4, the closed state of the spout T can be maintained reliably, and it is protected against unexpected external forces. Therefore, there is no possibility that the pouring tap T will be easily opened.

In addition, when the spout T is in an open state, the protruding piece 11 prevents the upper lid body B from tilting toward the base lid body A side due to the weight of the upper lid body B, the elastic restoring force of the flexible connecting piece 20, etc.
Even if the entire container Y is tilted to pour out the liquid in the container Y, the upper lid body B will not get in the way of the pouring operation, making the pouring operation easier. It becomes something that can be done.

Further, since the protrusion 12 and the locking body 7 having the recess 8 with which the protrusion 12 can be engaged are formed on the opposite side of the flexible connecting piece 20, the spout T can be kept in the closed state. In this case, the upper lid body B can be more reliably engaged with the base lid body A, and together with the effect of the stop protrusion 11, the spout stopper T can be prevented from being damaged by an unexpected external force or the like.
It is possible to reliably prevent the lid from being easily opened.

In addition, the tip portion of the stop protrusion 11 and the accommodation groove 4
Since the upper corner 6 is rounded, the tip of the stop protrusion 11 can smoothly get over the corner 6.

As explained above, according to the present invention, if the top lid falls and falls on the floor, if the top lid is lost, or when the top lid is poured out from the container, the top lid will be damaged by its own weight etc. It tilts toward the spout and does not interfere with the pouring process, making it possible to reliably maintain the open state of the pouring stopper.It also has a good appearance, and is simple in structure and easy to manufacture. This results in extremely beneficial effects in practice, such as making it suitable for mass production.
