Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a container spout for use in paper containers for milk, juice, etc., particularly Gebert-Tup seal paper containers.

(b) Prior Art As a device for installing a pouring spout in a Gebert-Tup Seal type paper container, one using a hinged lid as shown in Utility Model Application No. 61-77324 has been proposed.

(c) Problems that the invention aims to solve However, in this type, the spout is installed on the slanted roof, but the hinged lid gets in the way when pouring out the contents using the hinged lid. The lid is provided with a locking tool that also serves as a knob, and when the lid is opened, the locking tool is locked to the top of the Gebelt top seal portion.

In addition, the spout is generally made of plastic, and the locking device is also integrally formed, so it is not very strong and has the drawback of being difficult to lock or coming off during locking. In this case, the hinged lid must be held while pouring, and if the hinged lid closes during pouring, the liquid may be scattered outside the container such as a pot. Summer.

Also, since the hinged lid must be fully opened to lock the locking device, if you are not very careful when pouring out the contents, it will often overflow and the container, such as a pot, will be removed. This tendency becomes more pronounced as the content liquid increases. Therefore, the present applicant has proposed a spout in which the hinged lid flips up and locks in place without first providing a locking device, but because of the strong springing force, the hinged lid is usually closed. There is a risk that the hinged lid may pop up from its position.

(d) Means for solving the problem Therefore, in the present invention, when the hinged lid is opened, if the hinged lid is reversed, the hinged lid can stand on its own without requiring any other locking means. At the same time, when using a hinged lid, the hinged lid can be pushed into the raised edge of the opening, and when the lid is pressed, it can be maintained in the same position, ensuring that the hinged lid remains in the closed state. Then, the tip of the upright edge of the opening is tapered, a thick and strong base is formed on the opposite side, and the base is extended over the opening with the center part long and the ends short, and the hinge lid is inverted at the tip of the base. In the spout, the hinged lid periphery is tearably joined to the upper edge of the opening upright edge, and the central part of the inner end of the base protrudes inward, so that when the hinged lid is inverted, it can bend upward and become self-supporting. The present invention is characterized in that a hinge lid flip-up prevention mechanism is provided on the tip of the outer peripheral edge of the hinge lid and on the inner periphery of the tip of the upright edge of the opening, which includes a locking protrusion and an engaging portion, respectively.

(e) Example 1 is a hinged lid. 2 is a base 3 with an open upright edge, the tip of which is tapered, and the rear end of which is thick and strong.
Its inner end protrudes above the opening 4 into a triangular, trapezoidal, or semicircular cylinder with the center long and the ends short, and the hinge lid 1 extends from the outer edge. It is also convenient to make the base 3 slope toward the inner end. It is preferable to make the hinge lid 1 and the inner end of the base 3 have a difference in thickness, so that the hinge lid 1 is formed thin. However, it is preferable to form a groove or a wave-shaped bent part in the hinge part 1' at the boundary. You can also do that. Reference numeral 5 denotes an outer peripheral edge that hangs down from the hinge lid 1, and its outer lower end is joined 6 to the inner edge of the upper end of the opening standing edge 2. Further, it is preferable that the hinge lid 1 is formed into a medium-height shape, and the outer circumference is thick. Reference numeral 7 denotes a knob that protrudes above the tip of the hinge lid 1.
Reference numeral 8 denotes a locking protrusion provided at the tip of the outer circumferential edge 5, which is horizontally elongated, but the protrusion may be provided only at an appropriate portion. Reference numeral 9 denotes an engaging portion provided on the inner periphery of the tip of the opening upright edge 2, and the locking protrusion 8 and the engaging portion 9 constitute a mechanism for preventing the hinge lid 1 from springing up. Alternatively, the locking protrusion 8 can be attached to the inner periphery of the tip of the opening upright edge 2, and the engaging portion 9 can be attached to the tip of the outer periphery 5. Reference numeral 10 denotes a flange extending around the outer periphery of the lower end of the opening upright edge 2, which is an attachment part to the container.
11 is a projecting edge provided on the outer peripheral edge 5. 12 is a stopper provided at one end of the overhanging edge 11. In use, hold the knob 7 and pull it up to release the connecting part 6.
While separating, the hinge lid 1 separates from the opening upright edge 2 and rises. And the inclination direction of the base 3 and the hinge lid 1
The state in which the inclination direction of If you further pull up the knob 7, the hinge lid 1 will open via the hinge 1'.
is bent, and at the same time, its outer peripheral edge 5 rises upward beyond the inclined extension line of the base 3, and stops in the upward warped state due to the tension of the outer peripheral edge 5 or the thick portion (as shown in the fourth figure). Further, when the base 3 is extended horizontally, the hinge lid 1 must be in a state of being curved upward. In this case, if the hinge lid 1 is formed to have a medium height as in the embodiment shown in FIG. 1, the warp can be smoothly reversed like an umbrella. In either of these states, the opening 4 is open and liquid can be poured out. After use, simply by pressing the knob 7 or the hinge lid 1 from above, the outer peripheral edge 5 will fit into the opening upright edge 2, the overhanging edge 11 will hit the opening upright edge 2, and at the same time the locking protrusion 8 will be engaged. It is fitted over the mating portion 9 and is locked by the engaging portion 9, thereby closing the opening 4. (Fifth diagram) (e) Function and effect of the invention According to the invention as described above, the tip of the upright edge of the opening is tapered, a thick and strong base is formed on the opposite side, and a hinged lid is attached to the tip of the base. In the pouring spout, which is reversibly extended and the outer periphery of the hinged lid is tearably joined to the upper edge of the opening's upright edge, the center of the inner end of the base protrudes inward, and when the hinged lid is reversed, it bends upward and stands on its own. A mechanism for preventing the hinge lid from popping up is provided on the tip of the outer circumferential edge of the hinge lid and on the inner periphery of the tip of the upright edge of the opening, which consists of a locking protrusion and an engaging portion, respectively, so that it can be easily opened by pulling up the knob. The hinged lid stops in an upwardly curved state using the hinge at the base as a fulcrum, and can be locked and maintained in the open state without using any other locking means. Further, the hinge lid fits into the opening upright edge by simply pressing, and at the same time, the locking protrusion locks into the engaging portion to prevent it from springing up. Therefore, the spout can be opened and closed without touching the spout, making it hygienic. Moreover, there is no need for a mechanism to lock the hinge lid when opening the lid, and the structure can be simplified, resulting in an extremely easy-to-use pouring spout, simple structure, easy manufacture, and low cost, which has great practical effects. It is.
