  By the way, care foods and medicines are required to be ingested based on the prescriptions of dietitians and doctors, so when filling a pouch container with a single intake of such care foods and medicines, etc. It is necessary to ingest all of one bag, but in a pouch container equipped with a two-piece type spout that opens and closes the spout with a screw cap, it can be re-sealed with a screw cap after it is opened. In some cases, the taken care food, medicine or the like is taken in several times, and it cannot be said that it is suitable as a container for filling a single intake of care food or medicine. In particular, in the case of contents that change quality immediately after opening, the problem appears remarkably.

  On the other hand, in a pouch container equipped with a one-piece type spout that is opened by tearing off the closing part, once opened, it cannot be resealed. However, in the case of a pouch container equipped with such a spout, the contents are removed from the spout like a pouch container equipped with a two-piece type spout that opens and closes the spout with a screw cap. Since it cannot be filled, bag filling is adopted in which a filling port is formed in a part of the pouch fitted with the spout, the contents are filled from the filling port, and then the filling port is closed. .

  However, when bag filling is employed, a space for inserting the filling nozzle into the pouch is required, which causes problems that the pouch itself becomes larger than necessary and the manufacturing cost of the pouch increases.

  Therefore, an object of the present invention is to provide a spout that cannot be resealed once opened and can be filled with contents.

In order to solve the above-mentioned problem, the invention according to claim 1 is a spout comprising a spout body fixed to a container body, and a lid body that closes a spout part of the spout body. A cap that closes the spout portion, and a tamper ring that is detachably connected to a lower end of the cap, and the cap is not held by the spout portion, and is an upper half of the spout portion. The spout portion is closed by fitting to the lower half of the spout portion, and an external thread is formed on the outer peripheral surface of the spout portion. are formed female screw screwed to the external thread on the circumferential surface, wherein the tamper ring is in a state of being retained upwardly while being prevented from rotating in a direction to loosen the screw, threaded into the lower half of the spout By combining It is intended to provide a spout which is characterized in being held.

As described above, the spout of the invention according to claim 1 is screwed into the lower half of the spout portion in the spout body in a state in which the screw is stopped in the direction of loosening and is prevented from coming off upward . The cap that is detachably connected to the held tamper ring is fitted to the upper half of the spout portion in a state where it is not held by the spout portion, thereby closing the spout portion. So, if you pick the cap and turn it in the direction to loosen the screw , the cap will be cut off from the tamper ring and opened, but the cap itself will not be held by the spout, so re-seal after opening It is suitable as a container that can be filled with a single intake of nursing food or medicine.

Moreover, the pouch container to which this spout is attached has a tamper ring with a cap connected thereto in the same manner as a conventional pouch container to which a two-piece type spout that opens and closes the spout portion with a screw cap is attached. Since the pouch can be filled with contents from the spout portion of the spout body before being held by being screwed onto the lower half of the spout portion of the spout body, the pouch itself becomes larger than necessary. And the manufacturing cost of the pouch can be minimized.

In addition, the conventional screw cap type spout is a tamper in which the screw cap is connected by screwing the screw cap into the upper half of the spout portion while the tamper ring is prevented from rotating in the direction of loosening the screw cap. Although will retain the ring in the lower half of a spout in the spout body, this spout, by screwing the stop has been tamper ring turn in the direction to loosen the screw in the lower half of a spout portion Because the tamper ring with the cap connected is attached to the lower half of the spout part, the tamper ring is connected to the spout part of the spout body of the conventional screw cap type spout. With the screw cap attachment device, place the tamper ring with the cap connected to the spout body. Note can be attached to the outlet portion.

It is a longitudinal cross-sectional view which shows the state after opening of a spout same as the above.

  Hereinafter, embodiments will be described with reference to the drawings. As shown in FIGS. 1 and 2, the spout 1 is employed in a pouch container that is filled with a single intake of nursing food, medicine, etc., and a spout body 10 that is heat sealed to the pouch, The lid 20 is attached to the spout body 10.

  As shown in FIGS. 1 to 3, the spout body 10 includes a boat-shaped mounting portion 11 that is heat-sealed by a pouch, and a gripping portion 12 and a cylindrical shape that are sequentially connected to the upper portion of the mounting portion 11. The spout port 13 and a lead-out assisting portion 14 formed by a cross-shaped cross-shaped rib connected to the lower portion of the mounting portion 11, and the lead-out assisting portion 14 is inserted into the pouch. Thus, the pair of front and back exterior sheets forming the pouch are in close contact with each other so as not to close the outlet holes (not shown) for the contents formed in the mounting portion 11.

  The grip portion 12 has a pair of upper and lower flanges 12a and 12b that are formed at a predetermined interval and have a substantially rectangular shape. By gripping between the flanges 12a and 12b, the spout 1 and The pouch container equipped with the spout 1 can be transported.

  As shown in FIGS. 3 (a) and 3 (b), the spout portion 13 has a lower half formed thick, and the outer peripheral surface of the thick portion is radially directed from above. A circumferential protrusion 13a projecting outward, a male screw 13b, and four ratchet teeth 13c arranged at equal intervals in the circumferential direction and projecting outward in the radial direction are sequentially formed. When the outlet 13 is viewed from below, the amount of protrusion on the counterclockwise direction of the watch is the largest, and the amount of protrusion gradually decreases in the direction of rotation of the watch.

  As shown in FIGS. 1, 2, and 4, the lid 20 includes a cap 21 that closes the spout by fitting into the upper half of the spout 13 of the spout body 10, and the cap 21. The tamper ring 22 is connected to the lower end through a thin connecting portion 23 so as to be separable. A circumferential groove 21 a into which the upper end portion of the spout portion 13 is fitted is formed on the inner upper surface of the cap 21. Is formed.

  On the upper end surface of the tamper ring 22, two pairs of substantially trapezoidal protrusions are formed such that when the tamper ring 22 is viewed from the lower side, the rotation direction side of the timepiece rises directly above and the counter rotation direction side of the timepiece is lowered and inclined. 22a and 22a are formed. On the lower end surface of the cap 21, recesses 21b and 21b having substantially the same shape that fit into the two pairs of protrusions 22a and 22a are formed.

  Further, on the inner peripheral surface of the tamper ring 22, a circumferential ridge 22 b that projects from the upper side to the lower surface of the ridge 13 a of the spout portion 13 and projects outward in the radial direction, and the spout portion 13. There are formed female screws 22c to be engaged with the male screws 13b and eight ratchet claws 22d which are arranged at equal intervals in the circumferential direction and project in the rotational direction of the watch as viewed from the lower side. When the ring 22 is screwed into the lower half of the spout portion 13, the ratchet pawl 22d is deformed and gets over the ratchet teeth 13c of the spout portion 13, but once the screwed tamper ring 22 is loosened Even so, the ratchet pawl 22d is locked to the ratchet teeth 13c and the tamper ring 22 is prevented from rotating, so that it cannot be loosened (see FIG. 6).

  When the lid 20 is fitted into the spout portion 13 and the female screw 22c of the tamper ring 22 is screwed into the male screw 13b of the spout portion 13, as shown in FIGS. The upper surface of the protrusion 22b is locked to the lower surface of the protrusion 13a of the spout portion 13, and the peripheral groove 21a of the cap 21 is fitted to the upper end portion of the spout portion 13, so that the spout is formed by the cap 21. It is supposed to be blocked.

  Note that when the female screw 22c of the tamper ring 22 is screwed into the male screw 13b of the spout portion 13, even if the lid body 20 is rotated with the cap 21, the end face rising directly above the protrusion 22a formed on the tamper ring 22 Is locked to the corresponding portion of the recess 21 b formed in the cap 21, so that the cap 21 does not rotate relative to the tamper ring 22 and the cap 21 is not separated from the tamper ring 22.

  As described above, the spout 1 in which the spout portion 13 in the spout body 10 is closed by the lid 20 has a direction in which the screw 21 is loosened with the cap 21 as shown by the arrow in FIG. When turned counterclockwise (when viewed from directly above), the ratchet pawl 22d of the tamper ring 22 is locked to the ratchet teeth 13c of the spout portion 13 as shown in FIG. However, since the portion of the recess 21b corresponding to the inclined surface of the protrusion 22a formed on the tamper ring 22 starts to rotate along the inclined surface of the protrusion 22a, the cap 21 starts rotating. As shown in FIGS. 5B and 7, the thin-walled connecting portion 23 connecting the ring 22 is broken and the cap 21 is the tamper ring 22. Detached, it can be opened.

  Thus, since the cap 21 separated from the tamper ring 22 cannot be held in the spout portion 13 in the spout body 10, once the spout 1 is opened, it cannot be resealed. Therefore, it can be said that this spout 1 is suitable as a spout for a pouch container that is filled with a single intake of nursing food, medicine or the like.

  Moreover, the pouch container to which the spout 1 is attached is a tamper ring to which the cap 21 is connected in the same manner as a pouch container to which a two-piece type spout that uses a screw cap to open and close the spout is used. 22 can be filled in the pouch from the spout port 13 of the spout body 10 before the pouch 22 is locked to the lower half of the spout port 13 in the spout body 10, so that the pouch itself is more than necessary. It does not become large, and the manufacturing cost of the pouch can be minimized.

  In particular, the spout 1 is configured such that the tamper ring 22, which is prevented from rotating in the direction of loosening the screw, is screwed into the lower half of the spout portion 13, so that the tamper ring 22 to which the cap 21 is connected is connected to the spout portion 13. Since the lower half is attached and held, when attaching the lid 20 to the spout 13 in the spout body 10, the tamper ring is attached to the spout of the main body of the conventional screw cap type spout. The device for attaching the connected screw cap can be used as it is, and the existing device can be used effectively.

  In the above-described embodiment, the tamper ring 22 of the lid 20 is screwed into the spout portion 13 of the spout body 10, and the ratchet including the ratchet claw 22 d of the tamper ring 22 and the ratchet teeth 13 c of the spout portion 13. By controlling the rotation of the tamper ring 22 in the direction in which the screw is loosened by the mechanism, the tamper ring 22, that is, the lid 20 is held in the spout portion 13, but is not limited thereto. Adopting a so-called “plugging type” spout in which the tamper ring is prevented from rotating in at least one direction, and once inserted into the spout portion, it cannot be easily removed upward. You can also.

  In addition, when the spout body 13 of the spout body 10 is closed with the lid 20, when the lid 20 is picked with a finger and the tamper ring 22 is screwed into the spout 13, not only the cap 21 but also the tamper. Since the finger is also applied to the ring 22, the non-slip irregularities, grooves or ribs are provided on the outer surface of the tamper ring 22 so that the finger does not slip on the tamper ring 22 portion and only the cap 21 is turned. It is desirable to form it.

  In the above-described embodiment, the spout 1 including the derivation assisting portion 14 formed by the cross-shaped cross-shaped rib has been described. However, the shape and the like of the derivation assisting portion are not limited, and the derivation assisting portion is It can be omitted.

  Once opened, it can be used as a spout attached to a pouch container that is preferably not re-sealable.
