When the whipped cream package of Patent Document 1 is used, it is necessary to cut the vicinity of the mouth portion along the cutting line using scissors or the like, and it is necessary to separately prepare a cutting tool such as scissors. In addition, since the opening of the package is cut off with scissors, it is not possible to reseal and store the remaining whipped cream after use, so you have to either use it up or discard the remaining whipped cream. , it was necessary to store it in a separate packaging container.

Therefore, as a non-open type spout with a cap, a non-open spout with a throttle cap has been proposed as disclosed in Patent Document 2. To use it, apply force to the lid, which is integrally molded with the cylinder, to break the groove and expose the opening, then push up the base of the spout and fit the protrusion into the base of the spout. The spout is used with the opening of the cap protruding from the opening of the spout. Also, if you want to interrupt the decorating process midway through, push the tip of the spout into the spout and retract it. If you want to resume decorating, you will need to remove the lid and push up the base of the spout again. It takes time and effort to put in and take out the money. Furthermore, if the cap is pushed in too much, a problem may occur in which the cap falls out into the package containing the contents. In addition, if the contents adhere to the outer surface of the cap, or if contents such as whipped cream get into the gap between the cylinder and the cap, unnecessary contents protruding from the gap may be squeezed out, making it difficult to use as a decoration instead of the original one. The cream that has been squeezed out and squeezed out may adhere to the area around the trace of the cream that has been squeezed out, resulting in a state where the trace of the squeezed cream is not clean.

Furthermore, the pouch container of Patent Document 3 can be used as a piping bag by attaching the cap to the mouth of the spout, so when in use, a cap consisting of a separate part that can be attached to the spout is prepared. In addition to the need to keep the cap in place, it takes time and effort to attach the cap to the mouth, and if cream or other contents remain after use, the cap must be removed before use. There are many issues, such as the need to clean and store the caps in a separate location, which can be time consuming and lost due to storage.

An object of the present invention is to solve the above-mentioned problems, and to use a conventional spout cap as it is, without the need to replace the mouth of the spout with a base, and without the need to manufacture a new dedicated cap.

Further, FIG. 4 is a cross-sectional view cut in the BB direction shown in FIG. 2. As shown in FIGS. 1, 3, and 4, in the vicinity of the inner wall surface of the cylindrical body 1a below the mouth 1c, there is a pre-diaphragm that extends diagonally upward toward the central axis of the cylindrical body 1a. At the same time, a cylindrical protruding aperture opening 1e is formed. A doughnut-shaped connecting portion 1d is formed between the inner wall surface of the cylindrical body 1a and the lower end of the aperture opening 1e, which forms a horizontal surface along the circumference of the inner wall surface of the cylindrical body 1a. . The inner wall surface of the cylindrical body 1a and the lower end of the aperture opening 1e are connected to each other by the connecting portion 1d.

As shown in FIG. 3, the protruding inclination angle a of the aperture opening 1e is greater than or equal to 15 degrees and less than or equal to 75 degrees with respect to the horizontal plane of the connecting portion 1d. Furthermore, the vicinity of the tip of the aperture opening 1e is a notch opening 1f as shown in FIG. 2, and the peripheral wall surface of the notch opening 1f is shaped like a column cut out. It has a cylindrical surface. That is, the inner diameter of the cut opening 1f on the upper end 1fa side and the inner diameter of the lower end 1fb of the cut opening 1f are formed to be the same shape. As a result, when squeezing out the contents such as whipped cream contained in the pouch container and discharging it to the outside, it is possible to discharge the contents in a columnar shape while keeping the shape of the cut opening 1f, and the cream to be squeezed out. The traces can be squeezed out in a clean state.

Furthermore, when squeezing is finished, the mouth part 1c is turned straight down and swung up, thereby allowing the cream to taper straight and make a squeezed peak. The inclination angle a was explained to be 15 degrees or more and 75 degrees or less with respect to the horizontal plane of the connecting part 1d, but the inclination angle a that can make a more stable and beautiful aperture horn is 35 degrees. It is better to set the angle to 55 degrees or less.

As a result, by preparing and using a plurality of pouch containers 3, 31 each having a spout 1 with a squeezing opening according to the present invention having a different shape of the cut opening 1f, variations in the squeezing pattern of the contents such as whipped cream can be achieved. You can increase the number of decorations and implement various decorations.

FIG. 5 shows a state before the cap 2 is attached to the spout 1 with a throttle opening according to the present invention, and FIGS. 6 to 8 show a state in which the cap 2 is attached to the spout 1 with a throttle opening according to the present invention. There is. 7 is a top view of the state shown in FIG. 6, and FIG. 8 is a cross-sectional view taken along the line CC in FIG. As shown in FIG. 5 or 8, the spout 1 with a throttle opening according to the present invention is formed so that the tip of the throttle opening 1e does not protrude outward from the opening 1c. That is, when the spout 1 with a throttle opening of the present invention is sealed with the cap 2, the throttle opening 1e is connected to the cylindrical portion so that the tip of the throttle opening 1e does not come into contact with the back surface of the top plate 2a of the cap 2. It is formed to be housed inside the main body 1a. As a result, there is no need to construct a mold for a special cap to cover the spout 1 with a drawing opening, and a conventional spout cap can be used as is, reducing mold production costs. be able to.

Now, a method of filling the contents, such as whipped cream, using the pouch containers 3 and 31 to which the spout 1 with a squeeze opening of the present invention is attached will be explained. First, when the spout 1 with a constrictor opening is attached to the diagonal pouch container 3 by heat welding as shown in FIG. 9, a part of the film sheet on the upper end side of the diagonal pouch container 3 is not welded. The cage is open. Therefore, the opening portion becomes the filling port 3a, and filling of the contents can be carried out by inserting a filling nozzle of a filling machine into the filling port 3a.

The pouch container 31 shown in FIG. 10 has a different shape from the diagonal pouch container 3 shown in FIG. The pouch container 31 shown in FIG. 10 is of a type in which a filling port is not provided on the side of the pouch container 31, and the filling port is performed from the mouth portion 1c of the spout. As shown in FIGS. 1 and 2, the spout 1 with a throttle opening of the present invention allows filling even from the mouth of the spout, as shown in FIGS. 1 and 2. It has an opening diameter that is large enough to insert and fill.

However, if the insertion position of the filling nozzle is slightly misaligned due to the shape of the cut opening 1f or the insertion method of the filling nozzle, a part of the tip of the aperture opening 1e and a part of the filling nozzle may It is also assumed that there will be a collision and a part of the tip of the aperture opening 1e will be crushed. Therefore, our company can provide a nozzle auxiliary jig for filling from the cut opening 1f for the throttle spout 1 of the present invention. The nozzle auxiliary jig 4 shown in FIGS. 11 to 13 can be attached to the tip of a filling nozzle of a filling machine, as shown in FIG. 14.

The nozzle auxiliary jig 4 will now be explained. As shown in FIGS. 11 to 13, the nozzle auxiliary jig 4 includes a jig main body 4a having a substantially hemispherical side wall surface, and a center axis of the jig main body 4a with the tip of the filling nozzle 5a. A cylindrical nozzle insertion port 4b is formed that allows insertion and setting. 12 is a top view of the nozzle auxiliary jig 4 of FIG. 11, and FIG. 13 is a cross-sectional view of the nozzle auxiliary jig 4 of FIG. 12 cut in the direction D from D. Moreover, FIG. 14 is an image cross-sectional view of the nozzle auxiliary jig 4 attached to the filling nozzle 5a.

When the filling nozzle 5a with the nozzle auxiliary jig 4 attached thereto is lowered from the state shown in FIG. A portion of the side wall surface of the tool 4 that protrudes most outwardly comes into contact with a portion of the inner wall surface of the mouth portion 1c, thereby adjusting the position of the insertion site.

Furthermore, as shown in FIG. 17, when the filling nozzle 5a is lowered, the bottom surface of the jig leg portion 4c formed at the lower end of the nozzle auxiliary jig 4 is placed on the connecting portion 1d. The filling nozzle 5a is now held at the center of the mouth 1c. Thereby, the tip of the filling nozzle 5a does not interfere with the tip of the throttle opening 1e, and the contents can be filled from the cut opening 1f. The nozzle auxiliary jig 4 is preferably made of a soft elastic resin material such as rubber or elastomer. Note that the shape of the nozzle auxiliary jig 4 introduced this time is merely an example, and another form of nozzle auxiliary jig may be used.

In this way, it is possible to provide pouch containers 3, 31 of various variations to which the spout 1 with a constrictor according to the present invention is welded so that the user can freely select the shape and size of the cut opening 1f. I can do it. In addition, if the pouch container 3 or 31 is equipped with the spout 1 of the present invention, there is no need to use up the contents, and if the contents remain, seal them with the cap 2 and store them in the refrigerator. It becomes possible to use it repeatedly.

Next, the mold structure will be explained. A mold structure 61 in FIG. 19 is an image diagram of a mold in which the connecting portion 1d is not provided and an aperture opening is formed from the inner wall surface of the cylindrical body 1a. As shown in FIG. 19, if the end portion 61a of the mold has a thinned portion, as injection molding is repeated, the end portion 61a will not be able to withstand the mold clamping force and will be easily damaged. However, although a mold structure 6 having the shape of the throttle spout 1 of the present invention is shown in FIG. 18, if the shape of the throttle spout of the present invention is used as shown in FIG. The end portion 6a of the mold can be made so that there is no need to make the mold thinner or to make a part of the mold thinner. As a result, it is possible to obtain the mold structure 6 with good durability, and as a result, it is possible to provide a product that can reduce product cost.

Note that the spout 1 with a throttle opening according to the present invention may be provided with a flange portion 1j and a sandwich plate 1k as shown in FIG. The flange 1j is a plate-shaped flange that protrudes outward from the outer peripheral wall surface of the cylindrical body 1a further below the protrusion 1i. Further, the sandwiching plates 1k are formed near the back surface of the flange portion 1j, and are configured to sandwich the side surfaces of the cylindrical body 1a in a pair at positions parallel to the left and right.

The role of the brim portion 1j and the sandwiching plate 1k is that when filling the contents using the equipment 5 shown in FIG. By inserting the sandwich plate 1k along the U-shaped holder 5b, the collar portion 1j is caught in the U-shaped holder 5b, and the pouch container 31 is placed in a hanging state. From this state, the contents can be filled by inserting the filling nozzle 5a into the cut opening 1f.
