Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a pouring stopper attached to a container for containing a liquid.

[Prior art]

Conventionally, a paper container such as a Gobel top type has been used for the purpose of reducing the manufacturing cost and weight of the liquid container. Then, there is a dispenser provided with a synthetic resin so that the liquid stored in these paper containers can be easily poured out. For example, Japanese Utility Model Publication No. 58-37828, Japanese Utility Model Publication No. 60-62027, etc. are internally equipped with a spout for attaching to a spout of a liquid container and an opening blade for the spout. There has been proposed a liquid container pouring plug including an opening means and a cap that hermetically seals a spout.

[Problems to be solved by the device]

However, as described above, the conventional liquid container pouring plug is composed of the three parts of the spout, the opening blade, and the cap, so that not only the manufacturing cost of the pouring plug increases but also the assembling Also, there is a problem that the manufacturing cost becomes high because the attachment process becomes complicated. Therefore, it has been desired to devise a pouring plug for a liquid container which can reduce the number of constituent parts and the manufacturing cost.

[Means for Solving the Problems]

The present invention has been made in order to solve the above-mentioned problems of the prior art, and includes a pouring plug body attached to a pouring hole of a liquid container sealed by a breakable sheet, and the pouring plug body. It consists of a cap that can be opened and closed, and the spout body has an opening cylinder wall with an inner plug extending from the flange of the attachment part.
The inner plug, which is provided with an opening blade at the lower edge and is connected to the opening cylinder wall so as to be separable, engages with the pouring plug main body at the upper part of the outer peripheral wall facing the notch provided on the flange side from the tip of the opening cylinder wall. The present invention provides a pouring stopper for a liquid container, which has a possible engaging means.

[Action]

Since the liquid container pouring stopper according to the present invention has the above-mentioned structure, when the stored liquid is poured out, the cap is removed and the inner plug inside the pouring stopper body is pressed with a finger or the like. The inner stopper is separated from the connecting portion with the opening cylinder wall and descends to the rupturable sheet side that seals the liquid container, and the opening blade provided at the lower edge of the inner stopper hits the sheet and breaks. It is opened. The inner stopper having the opening blade does not drop into the liquid container even if it is separated from the opening cylinder wall, because the engaging means provided on the upper portion of the outer peripheral wall is engaged with and supported by the pouring stopper main body. .

【Example】

Next, the present invention will be described in detail based on an embodiment shown in the drawings. The liquid container pouring plug according to the present invention is a synthetic resin pouring plug composed of a pouring plug main body 1 and a cap 2 for opening and closing the pouring plug main body 1, and is mainly made of paper. It is used by being attached to a pouring hole a provided on the upper slope or the like of a Goebelt type liquid container made of a laminated sheet. The spout body 1 has an opening cylinder wall 12 extending from a flange 11 for attaching to a spout hole a of a liquid container sealed by a rupturable sheet (for example, a polyethylene film) b. Is formed so as to surround the spout A, and the spout A is internally provided with the inner plug 3. The inner plug 3 has an upper end portion of a body portion which surrounds a liquid discharge passage 31 and an air hole 32 and is severably connected to an upper end portion of an opening cylinder wall 12 at three places. The lower edge is provided with a saw-tooth-shaped opening blade 33 capable of breaking and opening the sheet b, and is installed so as to be able to descend to the side of the sheet b when the connection at the three locations is cut. In addition, the pouring plug body 1 is provided on the outer peripheral wall facing the notch 12a provided from the tip of the opening cylindrical wall 12 to the flange 11.
The engaging means 34 capable of engaging with the flange 11 of the is formed in a flange shape, and 90 degrees, 180 degrees and 2 degrees with respect to the engaging means 34.
An engaging protrusion 34a is provided on the upper side of the outer peripheral portion at a position of 70 degrees, and an engaging protrusion 12b corresponding to the engaging protrusion 34a is provided on the lower side of the inner surface of the opening cylindrical wall 12. Therefore, when the inner stopper 3 is pressed from above in the drawing and the connection at the three locations is cut, it drops to the side of the sheet b, so that the sheet b is pierced and opened, but the engaging means 34 pours. Since it engages with the tap body 1 (flange 11) and the engaging projections 34a and 12b are engaged with each other, it does not fall inside the liquid container. Sign
Reference numeral 12c is a screw for screwing the cap 2 screwed on the outer peripheral surface of the opening cylindrical wall 12. The cap 2 is provided with a screw (not shown) that can be screwed into the screw 12c of the spout body 1 on the inner surface of the cylindrical body, so that the spout A of the spout body 1 can be opened and closed. Has been formed. The separable connection between the inner plug 3 and the opening cylindrical wall 12 may be a connection at an appropriate position, for example, the middle stage or the lower stage. Further, since the air hole 32 of the inner stopper 3 is for replenishing the inside of the container with air in accordance with the amount of the liquid to be poured out and for stabilizing the pouring of the liquid, it is not necessary to provide the engaging means 34 adjacently. Although it is not present, it is necessary to arrange the pouring stopper so that it is always on the upper side when attaching the pouring stopper to the liquid container.

[Effect of device]

As described above, the liquid container pouring plug according to the present invention is a pouring plug body attached to the pouring hole of a liquid container sealed by a rupturable sheet, and the pouring plug body can be freely opened and closed. Since the cap consists of two parts, not only the manufacturing cost of the spout cap itself is low, but also the assembly process of the spout cap and the attachment to the liquid container are simplified, resulting in a large manufacturing cost. Reduction is possible. Further, since the inner plug having the opening function is completely installed inside the wall of the opening cylinder, the height can be kept relatively low, which is advantageous in that it does not become bulky when stacked. Then, by simply pressing the inner plug, the pouring hole is broken and opened, and the pouring can be easily performed.
