Description

[Detailed description of the invention] This invention relates to the improvement of a pouring stopper for a container that is attached to the mouth of a container into which liquid such as alcohol, milk, youth, vinegar, etc. is poured.

Normally, the mouth of this type of container is sealed with aluminum foil, paper, vinyl, etc. to completely seal off fragrance, taste, odor, etc. Therefore, conventionally, the top end was sealed inside the spout body. An inner stopper with a sharply pointed projection is inserted into the spout, and a lid is screwed onto the outside of the spout main body. Then, when opening the spout, remove the lid, grasp the inner stopper inside the spout body with your fingers, take it out, and insert the inner stopper repeatedly into the spout body with the sharp part facing downward. After that,
The lid was fastened to the outside of the spout body, and the seal at the mouth was opened using the sharp point of the inner plug. However, when opening the spout, not only is the opening operation troublesome, but the inner stopper must be grasped with fingers, which is extremely unsanitary.

Therefore, this invention was devised to solve the above-mentioned problems, and consists of a spout body and a lid that are mutually molded of plastic, and the spout body has a spout at the lower end. A male thread is provided on the outer circumferential surface of the cylindrical body that has a flange for mounting, and a substantially cylindrical inner plug is provided inside the cylindrical body with a sawtooth-shaped claw piece for pushing the seal at the mouth at the lower end of the cylindrical body. are arranged in a row so that they can be pushed down freely by a plurality of temporary fixing pieces, and a plurality of protrusions for pushing down are arranged at appropriate intervals on the inner circumferential surface of the cylindrical part of the inner stopper, and the cylinder from which the temporary fixing pieces are removed is A guide rail for guiding the inner plug to be pressed is provided on one opposing surface of the body and the cylindrical portion of the inner plug, and a guide piece for guiding the inner plug to be pressed is provided on the other opposing surface. On the other hand, the lid has an outer cylindrical part having a female thread on the inner circumferential surface of the lower part hanging from the periphery of the top plate, and a cut-out cylinder is attached to the lower end of the outer cylindrical part, and a knob is inserted through the cut-out groove. The outer cylinder part of the lid body is connected to the cylinder body of the pouring tap body, and the inner cylinder part is connected to the cylinder body of the spout body. By screwing together with male and female threads so that the lower end of the part comes into contact with the upper end of each protrusion of the inner stopper so that it can be pushed down freely, and the lower surface of the top plate comes into contact with the upper end of the cylindrical part of the inner stopper so that it can be pushed down, When opening the spout, the inner stopper can be pushed down reliably with an extremely easy operation to reliably open the seal of the mouth, and the inner stopper can be significantly hygienic without having to grasp and operate the inner stopper with your fingers as in the past. The present invention provides a spout stopper for a typical container.

An embodiment of the invention will now be described with reference to the drawings.

In the figure, A is a plastic spout body, and this spout body A has a flange 2 for attaching a mouth T to the bottom end of a cylindrical body 1 protruding outward. A male thread 3 is provided on the outer peripheral surface of the cylinder body 1.
On the inside thereof, a substantially cylindrical inner stopper 4 is formed so as to be pressable and continuous with four thin temporary fixing pieces 5. The inner stopper 4 has an upper end higher than the upper end of the cylindrical body 1, gradually expands outward as it goes upward from the same height as the upper end of the cylindrical body 1, and has a lower end higher than the lower end of the cylindrical body 1. A cylindrical portion 6 is provided at the same height as the cylindrical portion 6, and at the lower end of this cylindrical portion 6 there are claw pieces 7 for pushing out the seal S of the mouth portion T.

It is formed to be arranged. In addition, a pair of guide portions 10 for guiding the inner stopper 4 to be pressed are provided facing each other between the cylindrical body 1 and the cylindrical portion 6, excluding the temporary fixing pieces 5. 10 is provided with two guide rails 11 on the inner circumferential surface of one cylindrical body 1 (or on the outer circumferential surface of the cylindrical part 6), and on the outer circumferential surface of the other cylindrical part 6 (or on the inner circumferential surface of the cylindrical body 1). Two guide pieces 12 are provided, and each guide piece 12 is formed so as to be pushed down while being guided between each guide rail 11.

On the other hand, B is a lid body made of plastic, and this lid body B has an outer cylindrical portion 14 whose outer peripheral surface is knurled for non-slip purposes, which is vertically disposed around the periphery of a circular top plate 13. A female thread 15 corresponding to the male thread 3 is provided on the lower inner peripheral surface of the cylindrical portion 14, and the outer cylindrical portion 14
A cutout tube 16 having a diameter slightly larger than the diameter of the outer tube section 14 is connected to the lower end of the top plate 13 so that it can be freely cut off with a knob 18 via a cutout groove 17. An inner cylindrical portion 19 for pressing down the inner stopper 4 is formed vertically on the inside.

The outer cylindrical part 14 of the lid B is pressed against the cylindrical body 1 of the spout main body A, the lower end of the inner cylindrical part 19 is brought into contact with the upper end of each protrusion 9 of the inner stopper 4, and the top plate 13 It is screwed together with a male screw 3 and a female screw 15 so that the lower surface of the inner stopper 4 comes into contact with the upper end of the cylindrical portion 6 of the inner stopper 4 so as to be freely pushed down.

Since this device is configured as described above, when in use, the opening T of the container V is adjusted as shown in FIG.
The flange 2 of the spout main body A is attached to the peripheral edge, and when opening the spout T, the knob 18 of the lid body B is held between the fingertips and the cut-off tube 16 is forcibly cut off from the cut-off groove 17. After that, the inner cylinder part 19 is forcibly tightened downward by the screwing means of the female screw 15 of the outer cylinder part 14 and the male screw 3 of the cylinder body 1.
Since each protrusion 9 of the inner stopper 4 of the spout main body A is pushed down and the cylindrical portion 6 of the inner stopper 4 is pushed down by the top plate 13, each temporary stopper piece 5 is cut. By further tightening the lid body B downward, the seal S of the opening T is broken by each claw piece 7 at the lower end of the cylindrical portion 6 of the inner stopper 4, and the opening T is opened.

Therefore, when opening the mouth part T, the seal S of the mouth part T can be opened by an extremely easy operation of just cutting off the cut-off tube 16 and forcibly tightening the lid body B downward, so that the seal S of the mouth part T can be opened, unlike the conventional method. It is highly hygienic because the inner stopper 4 does not have to be grasped and operated with fingers.

Moreover, the inner stopper 4 is placed inside the cylindrical body 1 of the spout main body A.
are connected to each other so that they can be pressed down freely by a plurality of temporary fixing pieces 5, and a cut-off cylinder 16 is connected to the lower end of the outer cylinder part 14 of the lid body B so that it can be freely cut off via a cut-out groove 17. , screw the outer cylinder part 14 of the lid body B onto the cylinder body 1 of the spout body A with the male screw 3 and the female screw 15 so that the inner cylinder part 19 and the top plate 13 are pressed against the inner stopper 4 so that they can be pressed freely. By fitting them together, each temporary stopper piece 5 can be cut and the inner stopper 4 can be reliably pushed down when the mouth portion T is opened.
In addition, in this case, the cylindrical portion 6 of the inner stopper 4 of the spout main body A
The claw piece 7 provided in the shape of a sawtooth at the lower end allows the container V to be pressed down uniformly against the horizontal seal S of the container V, so that the seal S of the mouth T can be reliably opened.

Further, a guide rail 11 for guiding the inner stopper 4 to be pressed is provided on one opposing surface of the cylindrical body 1 of the spout main body A excluding the temporary fixing pieces 5 and the cylindrical part 6 of the inner stopper 4, and By providing a guide piece 12 for guiding the inner stopper 4 in pushing down on the other facing surface, the inner stopper 4 can be smoothly guided and pushed down when the mouth portion T is opened.

As explained above, according to this invention, when opening the spout, the inner stopper can be reliably opened by simply cutting off the cutoff tube and forcibly tightening the lid downward. Various effects such as being highly hygienic can be obtained without having to grasp and operate the inner stopper with your fingers.
