Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a pouring spout for use in paper containers for milk, juice, etc., especially Gebert-tup seal type paper containers.

(b) Prior Art As a device for leaving a pouring spout in a Gebert-Tup Seal type paper container, one using a hinged lid as shown in Utility Model Application Publication No. 11520/1983 has been proposed.

(c) Problems to be solved by the invention However, since the hinged lid gets in the way when pouring out the contents using the hinged lid, a locking device that also serves as a knob is provided on the hinged lid, and when the lid is opened, the hinged lid gets in the way. The locking tool is configured to lock onto the top of the Gebelt push seal portion.

However, this spout is generally made of plastic, and the locking tool is also integrally formed, so it is not very strong and may be difficult to lock or may come off during locking. There may be some drawbacks, in which case you have to hold down the hinged lid while pouring, and if the hinged lid closes at the spout, the poured liquid may be scattered outside the container such as a pot. It became.

In addition, since the hinged lid is fully opened to lock the locking device, if you are not careful when pouring out the liquid, it will often overflow and the container, such as a pot, will be removed. This tendency becomes more pronounced as the content liquid increases.

(d) Means for solving the problem Therefore, in the present invention, there is no need to lock the hinged lid even when the hinged lid is opened, but rather, the content liquid flows out while opening the hinged lid, and the amount of spillage is reduced. The hinged lid moves up and down according to the flow, and the hinged lid guides the outflow.
In addition, by making the opening according to the flow rate, it prevents overflow during outflow and allows for smooth dispensing, and also allows outflow without requiring any operations such as locking the hinged lid. The opening has a tapered tip and is equipped with a hinged lid that can be opened and closed freely.
Guide plates are hung from both ends of the back surface of the hinge lid, and the guide plates are narrowed in the direction of the tip corresponding to the tip of the hinge lid, and further, between the guide plates, the guide plates are inclined downward toward the tip. It is characterized by having a downward projecting portion.

(E) Embodiment 1 is a hinged lid, and its rear end is connected 3 to the opening periphery 2 so as to be openable and closable. It is convenient to form the opening peripheral edge 2 to an appropriate height. A flange 4 for attachment to the container is stretched around the outer periphery of the opening. The hinge lid 1 is formed into a pentagonal home base shape with a sharpened end that is the same shape as the opening 5, and its outer periphery 6 is made to hang down so as to fit with the opening periphery 2. A protruding band 7 is provided which engages with the opening periphery 2. Further, the outer peripheral edge 6 has an opening peripheral edge 2.
It is best to leave the stopper extended to prevent further invagination. 8, 8 is a guide plate and hinge lid 1
along the outer periphery 6 on the back side of the
Although the guide plates 8 and 8 are placed and suspended, the portions near the hinge lid 1 at the tips of the guide plates 8, 8 may be connected. The guide plates 8, 8 do not necessarily need to run along the outer circumferential edge 6, but may be provided linearly in a V-shape, or may be formed integrally with the outer circumferential edge 6.

It is preferable that the guide plates 8, 8 are made to hang lower toward the tip. Further, it is preferable that the rear end is spaced apart from the connecting part 3 or provided with a through hole or notch to ensure the air circulation part 12. 10
is a downward projecting portion, and the hinge lid 1 may be bulged downward or a separate tongue piece may be provided. The downward projecting portion 1
0 does not necessarily need to be provided over the entire area between the guide plates 8, 8, but it is preferable that it has an appropriate width. It is preferable that the tip portion thereof be installed near the tips of the guide plates 8, 8, but it is preferable to install it so as not to block the gap 9 between the guide plates 8, 8. In addition, it is recommended that the tip of the downward projecting portion 10 be formed with a stronger inclination and droop downward. Further, the hinge lid 1 is thinly connected to the opening peripheral portion 2, and is designed to be torn apart except for the connecting portion 3 when the hinge lid 1 is raised using a knob 11.

(f) Functions and Effects of the Invention The present invention provides a hinged lid that can be opened and closed freely over an opening with a tapered tip, has a guide plate hanging from both ends of the back surface of the hinged lid, and has a guide plate attached to the hinged lid. It is narrowed toward the tip in correspondence with the tip of the guide plate, and there is also a downwardly projecting part between the guide plates that slopes downward toward the tip, so it can be used by attaching it to a container, especially a Goebelt-tup-seal paper container. In this case, by tilting the container, the liquid content hits the lower protrusion of the hinged lid, is pushed up and guided by the guide plates, and is poured out from the gap between the guide plates and the opening periphery.

The amount by which the hinged lid is pushed up is determined by the amount of liquid poured out; when the amount of liquid poured out is small, the hinged lid is raised only a little, and when it is large, it is pushed up higher. Therefore, when pouring out the contents, the upper part is always in contact with the hinged lid, which prevents a large amount from accidentally overflowing.
In addition, the pouring operation is easy and there are no failures such as overflow.
There is no need to perform operations such as locking the hinge lid, and there is no need to worry about pressing the hinge lid or closing the hinge lid halfway. In addition, by installing information boards, garbage from outside,
The intrusion of insects etc. can be reliably prevented, and there is no need to touch the hinged lid, so it is extremely hygienic.

Furthermore, since it is integrally formed with the hinged lid and the spout consisting of the periphery of the opening, there is almost no increase in cost, which has great practical effects.
