Description

The present invention relates to a pouch having a spout with a hinge cap that is used by being attached to a pouch such as various seasonings, and more specifically, a state in which a spout fixed to the pouch and having a dispensing tube is attached to the end of a container. Thus, the present invention relates to a pouch having a spout with a hinge cap that is filled with contents through the pouring tube and that can be fitted with a hinge cap from above the pouring tube.

  The spout with a hinge cap includes a spout that is fixed to a container such as a pouch and has a dispensing cylinder, and a hinge cap that is attached to the spout and a cap body and an upper lid are connected via a hinge portion. Spouts are often used to give reliable liquid content to containers that are flexible and easy to dispose of, such as pouches, but are difficult to pour out. On the other hand, hinge caps are easy to open in addition to their openability and increase convenience, and are often used for containers that contain liquid contents that are used frequently such as seasonings, that is, frequently opened and closed. Has been.

A spout with a hinge cap that combines the advantages of the two in this way, with the spout being integrally plugged or screwed into the spout, the spout portion is welded and fixed to the end of the pouch, and is liquid-tight. As described above, the cap body is provided with a pull ring for opening to achieve the above-mentioned easy opening, and can be opened and closed with the hinged upper lid. I have to.
As an example, one described in Patent Document 1 below is known.
JP 2003-81315 A

  The spout with a hinge cap described in Patent Document 1 is such that the spout and the cap body are integrally formed via a hinge, and the object is to be virgin regardless of the diameter of the spout. It is excellent and has a configuration in which dust or the like hardly adheres to the spout portion. As described above, spouts with hinge caps are widely used because they are easy to use, but in order to fill liquid contents into containers such as pouches equipped with spouts with hinge caps, a separate pouch is provided. It is necessary to fill the liquid content from the mouth and then close the filling mouth.

  Since the spout fitted with the hinge cap described in Patent Document 1 is filled with the liquid content from a filling port provided separately in the pouch and then closed, the liquid content is high temperature, for example. If there is, it takes time to seal the filling port, and high-speed filling of the liquid contents becomes difficult. As in the current situation, when a spout with a hinge cap is frequently used in a pouch, regardless of the state of the liquid content, high-speed filling is a technical requirement that cannot be avoided. Therefore, to fill the pouch with the liquid content, without filling from the dedicated filling port, the pouch is filled directly from the spout welded to the pouch, and then the hinge cap is fitted to the spout, for example, sealed with a stopper. Then, there is a possibility that high-speed filling of liquid contents can be performed.

  However, when the hinge cap is driven into the spout, it is necessary to consider sufficiently the consistency between the hinge position of the hinge cap, that is, the opening / closing direction of the upper lid and the directionality of the pouch welded to the spout. Furthermore, it is necessary to sufficiently consider the displacement of the hinge cap immediately after the hinge cap is plugged into the spout, for example, to prevent the rotation of the hinge cap, and a spout with a hinge cap that fully considers them is desired.

  Therefore, the object of the present invention is to fill the container with the liquid content from the spout and then attach a hinge cap to the spout, so that the sealing can be finally performed. An object of the present invention is to provide a spout with a hinge cap capable of preventing the displacement of the hinge cap and capable of filling the liquid contents at a high speed.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention, the end portion between the sheets constituting the pouch having the periphery welded to the welded portion of the spout having the welded portion and the spout tube formed above the welded portion is welded and fixed. A pouch having a spout, and after filling the pouch with a liquid content from the spout, a hinge cap is plugged into the spout tube of the spout, and the hinge cap has a top surface and the top surface. from the outer peripheral edge consists of a top cover which is connected via a hinge to the cap body and the cap body comprising a skirt extending downwardly, at a position spaced from the position or the noted output tube connected to the outer peripheral surface of the infusion out barrel the circumferential position opposite to the solution deposition the longitudinal direction of the rib extending upward are two upright, the skirt lower end of the hinge cap, the four grooves of the rib and fitting at stoppered Formed and said note The lower outer peripheral surface of the cylinder is formed a step portion extending radially inwardly, that the opening direction of the upper cover of the hinge cap, is to face in the longitudinal direction or longitudinal direction perpendicular to the direction of the weld portion A pouch having a hinged cap spout is provided.

The pouch having a spout with a hinge cap according to the present invention has a spout welded and fixed to the end of the pouch, filled with liquid content through the spout pipe, and then sealed with a hinge cap. At that time, the engaging portion of the hinge cap skirt is engaged with the rib of the pouring cylinder, and the stepped portion extending radially inward is formed on the lower outer peripheral surface of the pouring cylinder. Seal it with a stopper. Therefore, the liquid content can be filled from the spout into the pouch, and when the hinge cap is fitted to the spout, it can be finally sealed by receiving the capping pressure at the step portion , and at the same time, the opening and closing direction of the upper lid and the pouch The directionality can be matched and the hinge cap can be prevented from being displaced, so that the liquid content can be filled at high speed.

Further, the pouch having the spout with a hinge cap of the present invention can engage the groove portion of the skirt of the hinge cap with the rib of the dispensing cylinder when the hinge cap is plugged and sealed to the dispensing cylinder. The effect can be obtained more easily and reliably.

In addition, the pouch having the spout with a hinge cap of the present invention is capable of directing the opening direction of the outer lid at a right angle to the longitudinal direction or the longitudinal direction of the welded portion when the hinge cap is stoppered and sealed to the dispensing cylinder. Since the rib of the dispensing cylinder can be engaged with the engaging part of the skirt of the hinge cap, in addition to the above effects, the opening direction of the upper lid is directed to the longitudinal direction of the spout welded part or perpendicular to the longitudinal direction. There is an effect that can.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

In these drawings, a spout 1 with a hinge cap is welded and fixed to an end portion 2b between sheets constituting a pouch 2 to which a peripheral edge 2a is welded, and is formed above the welded portion 3 and the welded portion 3. A spout 5 having a pouring tube 4, a top surface 6, and extending downward from the outer peripheral edge of the top surface 6, and is connected to the cap body 8 composed of a skirt 7 and the cap body 8 via a hinge 9. The hinge cap 11 is composed of an upper lid 10. The hinge cap 11 is plugged and sealed to the pouring cylinder 4, and a rib 12 extending upward is provided at a position spaced from the outer peripheral surface of the pouring cylinder 4. 7 is formed with a groove 13 (engagement portion) that engages with the rib 12 when plugged.

  The pouch 2 to which the spout 1 with a hinge cap is attached is not particularly limited as long as the welded portion 3 of the spout 5 can be welded to the end 2b, and any type and material may be used. In this Example 1, polypropylene is used because it is a hinge cap that is used for frequent dispensing such as seasonings, and is relatively opened and closed by the upper lid 10, and polyethylene is used for the spout. Yes. The pouch is a pouch made from a multilayer sheet whose inner layer is a polyethylene layer in consideration of welding with the spout.

  The spout 5 has a welded portion 3 for welding and fixing to the end portion 2 b of the pouch 2, and a dispensing cylinder 4 formed above the welded portion 3. The welded portion 3 has a boat shape in plan view, and the pouch 2 is welded in parallel with the longitudinal direction of the welded portion 3. A fitting recess 20 is annularly provided at the upper part of the outer peripheral surface of the dispensing cylinder 4. When the cap body 8 of the hinge cap 11 is plugged into the dispensing cylinder 4, the inner surface of the skirt 7 of the cap body 8 is formed. The provided fitting convex portion 7 a is locked in the fitting concave portion, so that the cap body 8 cannot be removed from the dispensing tube 4. As shown in FIG. 3, two ribs 12 are provided at positions facing the circumferential direction in the longitudinal direction of the welded portion at a position spaced from the outer peripheral surface of the extraction tube 4 located below the fitting recess 20. It is installed.

The cap body 8 of the hinge cap 11 is provided with a spout 21 on the top surface 6 and an outer peripheral wall 22 on the outside thereof . An annular protrusion 22a is provided on the upper outer peripheral surface of the outer peripheral wall 22, and the upper cover 10 is locked with a recess 23 provided on the inner surface of the end of the cylindrical wall 14 of the upper cover 10 which will be described in detail later. It can be maintained. Further, an inner cylinder 24 is provided on the inner side of the skirt 7 and is engaged with the inner side of the pouring cylinder 4. That is, a stopper part 25 surrounded by the skirt 7 and the inner cylinder 4 is formed, and the outlet cylinder 4 is plugged into the stopper part 25 to seal the outlet cylinder 4. As shown in FIGS. 1, 6, 7, 8, and 9, a stepped portion 28 extending radially inward is formed on the lower outer peripheral surface of the dispensing cylinder.

As shown in FIGS. 4 and 5, a groove 13 that engages with the rib 12 of the above-described dispensing tube 4, that is, four grooves 13 a, 13 b, 13 c, and 13 d are provided at the lower end of the skirt 7. . These grooves 13a, 13b, 13c, and 13d correspond to the shape of the rib 12, the groove 13a is provided in the skirt 7 below the center in the longitudinal direction of the hinge 9, and the remaining grooves 13b and 13d are on the left and right of the groove 13a. The position 13c separated by 90 degrees may be provided on the skirt 7 on the opposite surface of the groove 13a. The reason why there are four ribs 12a, 13b, 13c, 13d in the hinge cap 11 at 90 degrees apart from two ribs 12 in the spout 5 is that the hinge cap 11 is plugged and sealed into the dispensing cylinder 4 of the spout 5. When wearing, the opening direction of the outer lid 10 can be oriented in the longitudinal direction of the welded portion 3 or perpendicular to the longitudinal direction so that the opening direction of the upper lid 10 and the directionality of the pouch 2 are aligned, and the hinge cap is placed thereon This is because the displacement of 11 can be prevented.

  Further, a portion surrounded by the weakening line 15 inside the spout 21 is an opening planned portion 16 that can be removed by breakage, and a pull ring 17 is provided on the planned opening portion 16 via a column 17b. By pulling and pulling, it is possible to break the weakening line 15 and to remove the opening planned portion 16, that is, to open the opening. In FIG. 1, reference numeral 17 a denotes a slip stopper when a finger is put on the pull ring 17. On the other hand, sealing after opening is performed by fitting an inner ring 18 of the upper lid 10 described later into the spout 21 of the cap body 8.

  As described above, the upper lid 10 is attached to the cap body 8 of the hinge cap 11 through the hinge 9 so as to be freely opened and closed, and includes the top plate 26 and the cylindrical wall 14 extending downward from the outer peripheral edge thereof. 26, an inner ring 18 is provided, and a flange 27 is provided on the outer surface of the end of the cylindrical wall 14 facing the hinge 9, so that the upper lid 10 can be easily opened. Further, a recess 23 is provided on the inner surface of the end of the cylindrical wall 14.

Next, the usage method of the spout 1 with a hinge cap which becomes the said structure is demonstrated based on drawing.
First, it is divided into a pouch 2 and a spout 5 and a hinge cap 11 adapted to the pouch 2, and as shown in FIG. 6, the welded portion 3 of the spout 5 is welded and fixed to the end 2b of the pouch 2 formed by welding the peripheral edge 2a. To do. Next, as shown in FIG. 7, the liquid content filling pipe 30 is inserted into the spout cylinder 4 of the spout 5, and the liquid content 31 is filled into the pouch 2 from the filling pipe 30. When the filling is completed, as shown in FIG. 8, the hinge cap 11 is applied to the spout cylinder 4 of the spout 5 and sealed with a stopper (state of FIG. 1).

  At this time, it is determined in advance whether the opening direction of the upper lid 10 is directed to the longitudinal direction of the welded portion 3 or perpendicular to the longitudinal direction. When the opening direction of the outer lid 10 is directed to the longitudinal direction of the welded portion 3, it is plugged and sealed so that the grooves 12 a and 13 c of the hinge cap 11 are engaged with the ribs 12 of the spout 5. When it is oriented perpendicularly to the longitudinal direction, it is sealed with a stopper so that the grooves 12b and 13d of the hinge cap 11 are engaged with the rib 12 of the spout 5. Then, since the rib 12 is engaged with the rib 12 in the two grooves 13 facing each other among the groove portions 13a, 13b, 13c, and 13d, the rib 12 serves as a detent and the hinge cap 11 rotates on the spout 5. There is no.

In using the product of the present invention, the upper lid 10 can be opened from the cap body 8 by placing a finger on the collar 27 of the upper lid 10 and pushing it up. Next, by pulling the pull ring 17 with a finger, the weakening line 15 can be broken to remove the planned opening portion 16 and open. Then, the liquid content 31 in the pouch 2 can be poured into the necessary portion from the spout 21 of the cap body 8 in a necessary amount. When the cap body 8 is covered with the upper lid 10 after pouring the liquid content 31, the inner ring 18 of the upper lid 10 is fitted into the spout 21 in the process, and the liquid content 31 in the pouch 2 leaks. Seal so that there is no .

As mentioned above, although Example 1 of this invention was demonstrated, a specific structure is not limited to this, For example, even if the inside of a container is a pressurization state, it is applicable, and a rib is below a extraction pipe | tube. It should be understood that modifications within a range not departing from the gist of the present invention can be made as appropriate, such as being provided in a form connected to the skirt, or a groove extending upward from the lower end surface of the skirt wall. .
