Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a liquid pouring stopper that is attached to the mouth of a rectangular cylindrical paper container that mainly holds liquids such as milk and juice. Utility Application No. 60-67254 (Utility Application No. 183820, 1983) already filed by the applicant
This is related to the improvement of

(Prior art) In other words, the liquid pouring tap of Utility Application No. 60-67254 is
A flange protrudes outward from the lower periphery of the spout body having a low approximately hexagonal trapezoidal shape, and a lid plate is formed on the top surface of the spout body so as to be able to be opened and closed in the front and rear directions. was.

(Problem to be solved by the invention) However, when fitting this liquid pouring stopper into the mouth of a container from the inside and heat welding the peripheral edge of the mouth and the flange, it is necessary to support it with something. In addition, the work of attaching it to the mouth of the container is extremely troublesome, and the attachment position tends to shift, making it impossible to accurately attach it to the mouth of the container.

Therefore, this idea was devised to solve the above-mentioned problems, and when heat-welding the periphery of the mouth of the container and the flange, the flange is temporarily fixed. Not only does it make it extremely easy to attach to the mouth of the container, it also allows for accurate attachment to the mouth of the container, and the front wall of the spout body, where the most force is applied when opening and closing the lid plate, is extremely robust. becomes, and furthermore,
To provide a liquid pouring tap that can significantly stabilize the closed state of a lid plate.

(Means for solving the problem) In order to achieve the above-mentioned purpose, this invention has a flange for heat welding the mouth of the container on the lower periphery of the spout body, such as a low approximately hexagonal truncated pyramid shape. With the pieces protruding outward,
Further, in a liquid spouting faucet in which a lid plate is connected to the top surface of the spouting faucet body so as to be openable and closable in the front and back direction, the liquid spouting faucet is temporarily fixed to the mouth of the container on the outer surface of the opposing circumferential wall of the spouting faucet body. Locking pieces are provided at appropriate intervals to protrude diagonally downward, reinforcing pieces are provided to protrude from the inner surface of the front wall of the spout body, and furthermore, a cover plate is provided on the lower surface of the front end of the cover plate when the cover is closed. It has a protruding lid stopper that locks onto the front wall of the tap body.

(Function) By using the technical means described above, when the flange is fitted into the mouth of the container from the inside and the peripheral edge of the mouth is heat-welded to the flange, the flange is poured onto the top surface of the mouth of the container. Each locking piece on the spout body can be locked and temporarily secured, and the pressure to the upper surface of the mouth of the container can be strengthened. Make it latched to the wall.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

As shown in FIGS. 1, 4, and 5, a rectangular cylindrical paper container A is attached to the lower periphery of the spout body 1, which has a low, substantially hexagonal truncated pyramid shape with both corners cut off on the front end side. A flange piece 2 that is fitted into the spout B from the inside and heat welded is provided to protrude outward, and a top plate 3 is continuously provided on the rear end side of the upper surface of the spout body 1, so that the spout body A lid plate 4 is attached to the front end side of the upper surface of the spout 1, and is connected to the spout body 1 through a thin cut portion 5 and between the top plate 3 and the top plate 3 through a thin groove 6. Installed in series so that they can be opened and closed in any direction. In this case, the cut portion 5 is provided so as to be slightly raised from the upper end surface of the spout main body 1, as shown in FIG. Further, an arrow-shaped fitting groove 7 is provided in the center of the upper surface of the top plate 3, and an arrow-shaped fitting groove 7 indicating the lid opening direction is provided in the center of the upper surface of the lid plate 4. 8 is provided in a protruding manner so as to be fitted into the fitting groove 7 when the lid is opened, and furthermore, a knob piece 9 is provided in a protruding manner on the upper surface of the front end of the lid plate 4 to be gripped when the lid is opened and closed.

In the liquid spouting stopper formed in this way, a pair of locking pieces 10 temporarily fixed to the mouth B of the container A are arranged at appropriate intervals on the outer surfaces of the opposing circumferential walls, for example, both side walls, of the spout main body 1. A pair of triangular reinforcing pieces 11 are provided on the inner surface of the front wall of the spout body 1 at appropriate intervals, and a closing plate is provided on the lower surface of the front end of the lid plate 4. A lid retaining piece 12 is provided in a protruding manner to lock the lid plate 4 to the front wall of the spout main body 1 when the lid is closed.

Although the locking pieces 10 are shown as being protruded in pairs from the outer surfaces of the opposite side walls of the spout body 1 at appropriate intervals, the present invention is not limited to this in any way. As shown in FIG. 2, a pair of locking pieces 10 on the left side wall of the spout main body 1 and a pair of locking pieces 10 on the right side wall may be provided so as to protrude so as to be continuous with each other. Further, the locking pieces 10 may be provided in pairs on the outer surfaces of the opposing front and rear walls of the spout main body 1 at appropriate intervals.

(Effect of the invention) As described above, in this invention, the locking pieces 10 are provided on the outer surfaces of the opposing circumferential walls of the pouring tap main body 1 at appropriate intervals to protrude obliquely downward. As shown in the figure, when fitting into the mouth B of the container A from the inside and thermally welding the peripheral edge of the mouth B and the flange piece 2,
Since each locking piece 10 of the spout main body 1 can be temporarily secured by locking the upper surface of the mouth B of the container A, the opening B of the container A can be fixed temporarily without having to be supported by something like in the past. The installation work is extremely easy, and since each of the locking pieces 10 projects diagonally downward, the pressure on the upper surface of the mouth B of the container A is strong, and the installation position of the container A does not shift. It can be accurately attached to the mouth part B.

In addition, a reinforcing piece 11 is provided on the inner surface of the front wall of the spout body 1.
By protrudingly providing the lid plate 4, the front wall portion of the spout main body 1 to which the force is applied most when opening and closing becomes significantly stronger.
By protruding, the lid plate 4 can be locked to the front wall of the spout main body 1 when the lid is closed, so that the closed state of the lid plate 4 can be significantly stabilized.

Furthermore, a lid plate 4 is provided on the front end side of the upper surface of the spout body 1.
are connected to the spout body 1 through a thin cut section 5 so as to be openable and closable in the front and rear directions, and when opening the lid, the knob piece 9 is pinched and pulled slightly backward. Since the lid plate 4 can be easily torn off from the tearing part 5, not only the opening operation of the lid plate 4 is extremely easy, but also the lid plate 4 can be neatly torn from the tearing part 5.

As explained above, according to the liquid dispensing stopper of this invention, the peripheral edge of the mouth of the container and the flange can be temporarily fixed when heat welding, making it extremely easy to attach to the mouth of the container. Not only can it be attached to the mouth of the container accurately, but the front wall of the spout body, where the force is most applied when opening and closing the lid plate, is extremely strong, and the closed state of the lid plate can be easily fixed. Various effects can be obtained, such as being able to significantly stabilize the
