Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spout for bag and a bag provided with the spout, which is used for a bag containing a sauce, soy sauce, seasoning such as mirin, or powder and liquid such as detergent, lotion and the like. It is a thing.

[0002]

[Prior art]

 As this type of pouring tool, the one shown in FIG. 6 has been conventionally used. In the figure, 41 is a flange, to which a spouting cylinder 43 having a thread 42 is integrally provided. Reference numeral 44 denotes the spout member thus formed.

An opening 45 is formed at the center of the flange 41. Reference numeral 46 denotes a lid, which has a top wall 47 and a tubular portion 48, and the top wall 47 is provided with a tubular holding portion 50 for holding an opening member 49. Reference numeral 51 indicates a connecting portion of the opening member 49. The tip end of the above-mentioned opening member 49 has an opening 52 formed in a bifurcated cone shape.

In the case of manufacturing this spout, the spout member 44, the lid 46 and the opening member 49 are manufactured separately, and the opening member 49 is first pushed into the holding portion 50 of the lid 46 and then The lid 46 is screwed into the spout member 44, and the screwing is stopped at a position where the opening 52 of the opening member 49 does not penetrate the opening 45 of the flange 41.

The pour-out tool thus formed is used by being adhered to the bag body 53 containing the liquid or powder. The bag body 53 is made of a synthetic resin sheet. The user rotates the lid body 46 during use to screw the lid body 46 downward.

Then, the opening member 49 passes through the opening 45, and the sharp opening 52 is pressed while rotating with respect to the bag body 53 therebelow, so that the bag body 53 is torn apart. A passageway is formed there. Next, the user unscrews the lid body 46, tilts and presses the bag body 53, and the contents thereof are poured out from the pouring tube 43. Use in this way.

[0007]

[Problems to be solved by the device]

 However, the above-mentioned conventional spouting device has the following problems. As described above, the lid 46 is manually screwed in the middle of the length of the pouring tube 43 before being attached to the bag 53, as described above. The depth of the combination varies and is not constant.

Therefore, the screwing length at the time of opening is not constant, which is inconvenient for the user. In addition, the opening member 49 may have fallen off the holding portion 50 before use. Further, in the distribution stage, the lid 46 may be accidentally touched and screwed, and the lid 53 may be damaged.

The present invention was made in order to solve such various problems, and the purpose thereof is to make the gap between the opening 52 of the opening 49 and the bag body 53 constant, and therefore the user Can be opened by advancing a substantially constant screwing depth at the time of use, and even when the lid 46 is accidentally touched during the distribution stage, the bag 53 is not attached to the bag 53 as described in the conventional example. It is an object of the present invention to provide a spout for a bag body that can eliminate the risk of damage and a bag body provided with the spout.

[0010]

[Means for Solving the Problems]

 This invention for achieving the above-mentioned object will be described. It is made of a synthetic resin and has a flange 2 having an opening 1 and attached to a bag body; an external thread 3 integrally provided on the flange 2; A pipe 7 having a top wall 5 and a tube portion 6 which are screwed into the pipe 4 and are longer than the length of the tube portion 6 integrally provided on the lower surface of the top wall 5. An opening member 9 which is formed and has an opening 8 at its tip; disposed between the tubular portion 6 and the flange 2 and provided on either one of the tubular portion 6 and the flange 2 via a weakening portion 10. A spouting device for a bag, which is characterized by comprising a band 11; Next, the pouch provided with the pour tool is a pouch provided with the pour tool, which comprises the pouch provided with the pour tool configured as described above.

[0011]

[Action]

 The pouring tool is configured as described above, and the band 11 is provided between the lid 7 and the flange 2, so that the top wall 5 of the lid 7 when the lid 7 is screwed in the direction of the flange 2 The distance between the opening 8 of the opening member 9 which is integrally provided on the inner surface and the lower end of the opening 1 of the flange 2 can always be kept constant, so that the user must always remove the band 11 after that. The bag can be opened by a certain length of screwing. That is, the action can be stabilized.

Further, as described in the conventional example, it is possible to prevent the opening member 9 from dropping off from the lid 7 before use, and the depth of pushing the opening member 9 into the holding portion 50 can be eliminated. There was also a problem of disagreement, but that can be solved.

Further, in the distribution stage of the product, as in the conventional case, the lid 7 is erroneously touched, and the lid 7 is screwed forward, thereby breaking the bag body provided with the pouring tool. You can also prevent it.

[0014]

【Example】

 In FIG. 2, reference numeral 2 denotes a flange to be attached to the bag body, which is made of synthetic resin, and the above-mentioned attachment is usually performed by an adhesive. For that purpose, an adhesive is applied to the lower surface of the flange 2 in advance, and release paper is attached to the lower surface. When using, the release paper is peeled off to expose the adhesive and the synthetic resin sheet. It is attached to the bag made of plastic.

An opening 1 is formed at the center of the flange 2. Reference numeral 4 denotes a spouting cylinder, which is provided integrally with the flange 2 and has a thread 3 formed on the outside. 4a represents the spout member formed in this way. Next, in FIG. 1, reference numeral 7 denotes a lid, which is made of synthetic resin and includes a top wall 5 and a tubular portion 6, and an opening member 9 is integrally provided on the lower surface of the top wall 5, The length of the opening member 9 is longer than that of the cylindrical portion 6.

The opening 8 at the lower end is bifurcated and sharply formed. Next, reference numeral 11 is a band, and the band 11 is provided on either the tubular portion 6 or the flange 2 via a weak lower portion 10. What is shown in FIG. 1 is the case where it is provided on the cylindrical portion 6, and what is shown in FIG. 4 is the case where it is provided on the flange 2.

The band 11 has an opening 13 and a knob 14 as shown in FIG. The thus-formed pour-out tool is attached to the bag body 15 formed of a synthetic resin sheet as described above and containing the contents, as shown in FIG. 4 as an example. This attachment may be adhesion or fusion.

It should be noted that in FIG. 1, reference numeral 16 denotes a stopper, which abuts on the upper portion of the pouring tube 4 and stops further screwing. The user holds the knob 14 of the band 11 and pulls it in the circumferential direction, and tears and removes it from the thin weakened portion 10. Then, the lid body 7 is screwed, the opening 9 is rotated, the opening 15 opens the bag body 15, and then the lid body 7 is unscrewed, and the lid body 7 is screwed into the bag body. Push out the contents of the item.

[0019]

[Effect of device]

 Since the present invention is configured as described above, the user can stably open the bag body 15 by screwing the lid body 7 by a certain length when opening the bag body 15. It should be noted that this also solves the inconsistency in the screwing length due to the inconsistency in the pushing depth of the opening part agent 44 of the conventional pour tool into the holding part 50, and the stable opening can be performed as described above. It is.

Further, as described in the conventional example, it is possible to prevent an accident in which the opening member 49 has already fallen off before use. In addition, even if the lid 7 is accidentally touched at the distribution stage, it is possible to prevent the lid provided with the spout from being damaged.
