Description

  The present invention relates to a spout that is provided in a container filled with liquid or paste-like contents and constitutes a spout for the contents, and in particular, by attaching an adapter to the spout member, the spout path of the spout member is provided. It relates to a spout that is opened and the contents can be dispensed.

  A spout is known which is provided in a container filled with liquid or paste-like contents and constitutes a spout for the contents. For example, a spout provided in a bag-like container such as a pouch container is configured to include a spout member that is thermally welded or bonded to the bag-like container, and an adapter or cap that is attached to the spout member. Appropriate adapters and caps are selected according to the contents. For example, in a spout of a container filled with a paste-like content, a wide-mouthed straw-shaped adapter is widely used to ensure the fluidity of the content.

  Further, in such spouts, a sealing wall for sealing the pouring path of the spout member is provided, and the sealing wall is opened by attaching an adapter or a cap to the spout member. (For example, refer to Patent Documents 1 and 2). According to such a spout, it is possible not only to prevent deterioration of the contents, but also to have good openability.

However, in the spout shown in Patent Document 1, a conical protrusion is formed on the cap, and the protrusion breaks through the central portion of the sealing wall. Since it remains in the entire periphery, not only the effective cross-sectional area of the pouring path becomes small, but also the pouring of contents may be hindered.
In addition, this requires a cut line for hinge coupling formed on the peripheral edge of the sealing wall and a cut line for cutting formed on the inside thereof, so the shape is complicated by two types of cut lines. Therefore, there is a problem that the manufacturing cost increases.

On the other hand, the spout shown in Patent Document 2 has a cutting cylinder (built-in member) that is pushed into the pouring path as the adapter is attached, and breaks the sealing wall at the end of the cylinder. It is possible to open the sealing wall only by forming one type of cut line.
In this case, the pierced sealing wall remains on one side of the inner periphery of the pouring path, with the uncut portion of the cut line as a hinge, and the effective cross-sectional area of the pouring path becomes large, and the contents There is also an advantage that the pouring of is smooth.
Japanese Patent Laid-Open No. 11-1248 (page 4, FIG. 5) JP 2002-68268 A (3rd page, FIG. 3)

  However, in the spout shown in Patent Document 2, when the adapter is attached, the entire cylinder end of the cutting cylinder reaches the cutting line, so that the entire cutting line may be cut and the sealing wall may fall off. In such a case, the dropped sealing wall may block the pouring path, making it difficult to pour out the contents, or hindering stable pouring of the contents.

  The present invention has been considered in view of the above circumstances, and has a cutting cylinder that is pushed into the pouring path as the adapter is attached, and the sealing wall is cut by cutting the sealing wall at the end of the cylinder. It is possible to open the sealing wall only by forming one kind of cut line at the peripheral edge, and the unsealed sealing wall is used as a hinge at the non-cut portion of the cut line, and the inner peripheral part of the dispensing path is the same. By leaving it on the side, the effective cross-sectional area of the pouring path can be increased, the contents can be smoothly poured out, and the uncut portion of the incised line can be securely cut without cutting the entire incised line. It aims at providing the spout which prevents the omission of the sealing wall by leaving it and can avoid the pouring failure by the occluded sealing wall.

  In order to achieve the above object, the spout of the present invention is a spout for pouring out the contents of a container, and is provided in the container to form a pouring path for the contents, and this pouring path is provided at the peripheral portion. A spout member that is sealed with a sealing wall in which a cut line is formed, an adapter that is mounted on the spout member, and the cut line that is pushed into the discharge path along with the mounting of the adapter. The cylinder end of the cutting cylinder is inclined with one side as a tip, and a non-cutting action part that does not reach the incision line is provided on the other side.

If the spout is configured in this way, it has a cutting cylinder that is pushed into the pouring path as the adapter is attached, and by cutting the sealing wall at the end of the cylinder, one kind of material is provided at the peripheral edge of the sealing wall. The sealing wall can be opened only by forming the cut line.
In addition, since the unsealed sealing wall can be left on one side of the inner peripheral portion of the pouring path, the uncut portion of the cut line can be left as a hinge, so that the effective cross-sectional area of the pouring path becomes large and the contents are poured out. Can be done smoothly.
In addition, the tube end of the cutting cylinder has a non-cutting action portion that does not reach the cut line, so that the non-cut portion is surely left in the cut line. Outgoing obstacles can be avoided.

Further, in the spout of the present invention, the non-cutting action part is constituted by an inclined surface having the same angle as the one side part.
If the spout is configured in this manner, the cylindrical end shape of the cutting cylinder can be simplified, the complexity of the structure can be avoided, and the manufacturing cost can be suppressed.

In the spout of the present invention, the non-cutting action part is constituted by a notch formed at the cylinder end.
If the spout is configured in this way, the present invention can be implemented by a simple design change that forms a notch at the end of the cutting cylinder.

Moreover, the spout of this invention is set as the structure by which the said adapter and the said cutting cylinder are integrally molded.
If the spout is configured in this way, not only the number of spout parts can be reduced, but also the manufacturing cost can be reduced.

Moreover, the spout of this invention is set as the structure by which the said adapter is screw-fitted with respect to the said spout member.
If the spout is configured in this way, it is possible to reduce the pushing operation force of the cutting cylinder, and when the adapter and the cutting cylinder are integrally formed, the cutting cylinder can be pushed into the pouring path while being rotated. Can be cut easily.

In the spout of the present invention, the spout member includes an overrun restricting portion that engages with a screw portion of the adapter to restrict overrun of the adapter.
By configuring the spout in this way, it is possible to avoid the inconvenience that the tube end of the cutting tube cuts the non-cut portion of the cutting line due to overrun of the adapter, and the sealing wall can be prevented from falling off.

As described above, according to the present invention, there is a cutting cylinder that is pushed into the pouring path as the adapter is attached, and the sealing wall is cut at the end of the cylinder, so that the peripheral edge of the sealing wall is aligned. It is possible to open the sealing wall only by forming a kind of cut line.
Also, by leaving the unsealed sealing wall as a hinge on the uncut part of the cut line and leaving it on one side of the inner periphery of the pouring path, the effective cross-sectional area of the pouring path becomes large and the content can be poured smoothly. Can be done. Furthermore, by leaving the non-cut portion of the cut line without cutting all the cut lines, it is possible to prevent the sealing wall from falling off and to prevent the pouring trouble due to the dropped sealing wall.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Although there is no restriction | limiting in particular as a material which forms the spout 1, When the bag-like container 2 is formed with a resin film, it is preferable to form the spout 1 with a thermoplastic resin such as polypropylene or polyethylene. When the spout 1 is formed of such a material, the spout 1 is thermally welded to the bag-like container 2 simply by inserting the base of the spout 1 into the unsealed portion of the bag-like container 2 and heat-sealing from the front and back. It becomes possible.

  The spout is attached to the bag-like container at the center of the upper part of the container shown in FIG. 1, at the left or right of the upper part, or at the left or right corner of the upper part of the container. It can be attached at any position according to the purpose of use.

Fig.2 (a) is a front view of the spout which concerns on 1st embodiment, FIG.2 (b) is a longitudinal cross-sectional view of a spout.
The spout 1 is provided in the bag-like container 2, and includes a spout member 10 that forms a spout passage 11 for contents, an adapter 20 that is attached to the spout member 10, and a spout passage 11 that is attached to the adapter 20. And a cutting cylinder 30 to be pushed in.
In the spout 1 of the present embodiment, the adapter 20 and the cutting cylinder 30 are integrally formed, but each may be formed separately.

Fig.3 (a) is a front view which shows the spout outlet member of the spout which concerns on 1st embodiment, FIG.3 (b) is a top view which shows a spout member, FIG.3 (c) shows a spout member. FIG. 3D is a side view showing the spout member, and FIG. 3E is a longitudinal sectional view showing the spout member.
As shown in these drawings, the spout member 10 includes a mounting portion 12 attached to the bag-like container 2, a spout cylinder portion 13 that forms the spout passage 11, and a seal that seals an intermediate portion of the spout passage 11. A stop wall 14, a screw part 15 formed on the upper outer peripheral surface of the extraction cylinder part 13, and a flange part 16 formed below the screw part 15 are provided.

The attachment part 12 is formed so as to protrude from the lower part of the extraction cylinder part 13 to the left and right, and to be thinner toward the protruding end side. By making the attachment portion 12 in such a shape, heat sealing when attaching to the bag-like container 2 is facilitated, a sufficient welding area is secured, and the bag-like container 2 and the attachment portion 12 are firmly coupled. can do.
Note that the cut line 14a is not necessarily provided on the entire circumference, and may be formed only on a part of the peripheral edge. In particular, it is not necessary to form the cut line 14a for a portion remaining in an uncut state.

  The inner diameter of the extraction cylinder portion 13 is larger on the lower side than on the upper side with the formation position of the sealing wall 14 as a boundary. The upper inner diameter of the extraction cylinder portion 13 is set so that the cutting cylinder 30 can be fitted, and the upper inner diameter of the extraction cylinder portion 13 is the thickness of the sealing wall 14 to be pierced by the cutting cylinder 30. The dimensions are set to take this into account.

The sealing wall 14 is formed as a thin film as a whole, and a thinner cut line 14a is formed on the entire periphery of the sealing wall 14. Although this cut line 14a is cut by the cutting cylinder 30, a part thereof remains in an uncut state, and this is used as a hinge so that the sealing wall 14 remains on one side of the inner peripheral portion of the extraction path 11. Yes.
The screw portion 15 is formed on the upper outer peripheral surface of the dispensing tube portion 13, and the adapter 20 is screwed therein. The adapter 20 screwed to the upper outer peripheral surface of the extraction cylinder portion 13 is restricted from being further screwed by the lower end of the adapter 20 coming into contact with the flange portion 16.
In addition, the attachment means of the adapter 20 with respect to the spout member 10 is not limited to screw fitting, You may use another attachment means.

The screw thread formed in the screw part 15 is formed in a discontinuous manner for convenience in molding. Therefore, overrun of the adapter 20 may occur due to overcoming of the screw thread, but in this embodiment, the adapter 20 is formed by forming the two types of overrun restricting portions 17 and 18 in a portion where the screw thread is not formed. 20 overruns are prevented.
The 1st overrun control part 17 is a convex part formed over a wide range in the right-and-left both sides where the screw thread is not formed among the upper outer peripheral surfaces of the extraction cylinder part 13. The first overrun restricting portion 17 formed in this way abuts on the top of the screw thread formed on the adapter 20 side, and suppresses the play of the adapter 20 with respect to the dispensing tube portion 13, thereby preventing the screw thread. To prevent overcoming.
The second overrun restricting portion 18 is a hemispherical convex portion formed at an intermediate position of the screw thread discontinuous portion, and is formed on an extension line of the screw thread. The second overrun restricting portion 18 formed in this way is engaged with the side portion of the screw thread formed on the adapter 20 side, thereby preventing the screw thread from getting over.

4A is a front view showing the adapter of the spout according to the first embodiment, FIG. 4B is a plan view showing the adapter, FIG. 4C is a bottom view showing the adapter, and FIG. d) is a side view showing the adapter, and FIG. 4E is a longitudinal sectional view showing the adapter.
As shown in these drawings, the adapter 20 includes a fitting cylinder portion 21 that is screwed into the upper portion of the spout member 10, a dispensing nozzle 22 that extends upward from the fitting cylinder portion 21, and a fitting cylinder. The screw part 23 formed in the internal peripheral surface of the part 21 and the plate-shaped attachment / detachment operation part 24 extended from the fitting cylinder part 21 right and left are provided.

The fitting cylinder part 21 is screwed to the screw part 15 of the spout member 10 via the screw part 23 of the inner peripheral part. At this time, the screw fitting operation of the fitting cylinder part 21 with respect to the spout member 10 is facilitated by turning the attachment / detachment operation part 24 with a finger.
The dispensing nozzle 22 is continuously provided with a large-diameter portion 22a on the proximal end side and a small-diameter portion 22b on the distal end side. When the contents of the bag-like container 2 are liquid, it is possible to pour the contents from the small diameter portion 22b without any problem, but when the contents are pasty with poor fluidity The opening area of the pouring nozzle 22 can be expanded by cutting the pouring nozzle 22 at the large diameter portion 22a.

  The cutting cylinder 30 is pushed into the extraction channel 11 as the adapter 20 is attached, and cuts the cutting line 14 a at the cylinder end 31. The cutting cylinder 30 of the present embodiment is integrally formed with the adapter 20 and extends downward from the lower end of the pouring nozzle 22. The cylinder end 31 of the cutting cylinder 30 is cut obliquely so that one side becomes the tip, and a non-cutting action part 32 that does not reach the cut line 14a is formed on the other side. That is, the non-cutting action part 32 is a part formed so as to be positioned above the cut line 14a even if the cutting cylinder 30 is pushed into the pouring path 11 to the limit position. Thereby, it is possible to reliably leave an uncut portion in a part of the cut line 14a and prevent the sealing wall 14 from falling off. In addition, the non-cutting action part 32 of this embodiment is an inclined surface having the same angle as that of the one side part, and the cylinder end shape of the cutting cylinder 30 is not complicated.

  When the adapter 20 is mounted on the spout member 10, the cutting cylinder 30 formed as described above is fitted into the spout passage 11 of the spout member 10, and the adapter 20 is screwed into the spout member 10. Then, it is pushed into the extraction channel 11 while rotating. When the cylinder end 31 of the cutting cylinder 30 reaches the sealing wall 14, first, the tip of the cylinder end 31 breaks through the cut line 14a, and then the cylinder end 31 moves along the cut line 14a, and the cut line 14a gradually increases. However, at the corresponding portion of the non-cutting action part 32, the cut line 14a does not receive the cutting action and remains as a non-cutting part. When the uncut portion of the cut line 14a is reduced, the sealing wall 14 rotates using the non-cut portion of the cut line 14a as a hinge and remains on one side of the inner peripheral portion of the dispensing path 11.

According to the spout 1 of 1st embodiment comprised as mentioned above, it has the cutting cylinder 30 pushed into the extraction channel 11 with attachment of the adapter 20, and cut | disconnects the sealing wall 14 by the cylinder end 31 By doing so, the sealing wall 14 can be opened only by forming one kind of the cut line 14 a at the peripheral edge of the sealing wall 14.
Moreover, since the unsealed part of the cut line 14a can be used as a hinge and the sealing wall 14 that has been opened can be left on one side of the inner peripheral portion of the pouring path 11, the effective cross-sectional area of the pouring path 11 is increased. Goods can be poured out smoothly.
In addition, the cylinder end 31 of the cutting cylinder 30 has a non-cutting action portion 32 that does not reach the cut line 14a, and the cut wall 14a is reliably left with a non-cut portion, thereby preventing the sealing wall 14 from falling off. Thus, it is possible to avoid the dispensing failure caused by the sealed wall 14.

Moreover, in the spout 1 of this embodiment, since the non-cutting action part 32 is comprised by the inclined surface of the same angle as the one side part of the cylinder end 31, the cylinder end shape of the cutting cylinder 30 is simplified, and the structure of The complexity can be avoided and the manufacturing cost can be suppressed.
Moreover, in the spout 1 of this embodiment, since the adapter 20 and the cutting cylinder 30 are integrally formed, the number of parts of the spout 1 can be reduced.

  Moreover, in the spout 1 of this embodiment, since the adapter 20 is screwed with respect to the spout member 10, the pushing operation force of the cutting cylinder 30 can be reduced. In addition, in the present embodiment in which the adapter 20 and the cutting cylinder 30 are integrally formed, the cutting cylinder 30 can be pushed into the extraction passage 11 while rotating, so that the cutting line 14a can be easily cut. is there.

  Moreover, in the spout 1 of this embodiment, since the spout member 10 is formed with the overrun restricting portions 17 and 18 that engage with the screw portion 23 of the adapter 20 to restrict the overrun of the adapter 20, the adapter The overrun of 20 can avoid the inconvenience that the tube end 31 of the cutting tube 30 cuts the non-cut portion of the cutting line 14a, and the sealing wall 14 can be prevented from falling off.
