Description

  The present invention relates to a break-up spout formed by connecting a sealing cap integrally formed via a thin-walled portion that can be broken off to a spout tip of a spout tube portion that is bonded and fixed to a mouth portion of a bag-like container. .

2. Description of the Related Art Conventionally, containers formed in a bag shape with a flexible material such as a plastic film or aluminum foil are widely applied to various food containers, medical containers containing chemicals, and the like.
Such a bag-like container is provided with a spout called a spout, which is made of a plastic cylindrical body having both ends open. As such a spout, for example, Patent Document 1 shows in FIG. Thus, the spout closing body 73 (the knob portion 14a) is connected to the tip of the pouring cylinder 71 (spout cylinder portion 12) via the horizontal score 72 (thin wall portion 13). The horizontal score 72 is integrally connected to the outer surface of the lower end portion of the leg tube 74 and the inner surface of the upper end portion of the dispensing tube 71 so as to close the upper end of the horizontal score. A break-out spout 70 is described in which the sealing is maintained until 72 is separated from the dispensing cylinder 71.

Japanese Patent Laid-Open No. 2004-210321

In the conventional spout 70, at the time of opening, the closing body 73 is grasped with fingers and twisted in a pushing manner to break the horizontal score 72 and form a spout at the upper end of the spout cylinder 71. At this time, the peripheral edge of the leg cylinder 74 of the cut-off closure 73 may be in a state of being caught in the formed spout.
In this way, once the peripheral edge of the separated leg tube 74 is inserted into the spout and bites into the spout, there is a problem that it is difficult for an infant or an elderly person with weak power to remove the leg tube 74. It was.
Moreover, since the extraction tube 71 and the leg tube 74 are connected only by the annular horizontal score 72,
There is also a problem that the durability when the external force is applied is poor and the annular horizontal score 72 is easily broken.

  The present invention has been made to solve the above-described conventional problems. The sealing cap separated at the time of opening eliminates the fact that the sealing cap that has been formed by breaking into the spout formed in a fractured manner does not bite into the sealing cap and the spout tube. It aims at providing the tear-off spout excellent in durability which increased the connection strength with a part.

FIG. 3 is a partial front half sectional view, and FIG. 4 is a side half sectional view thereof. FIG. 5 is a partial front half sectional view after opening, and FIG. 6 is a side half sectional view thereof.

As shown in the drawing, the break-out spout 10 according to the embodiment has a joint 11 that can be fixed to a pour-out opening such as a pouch container by an adhesive, heat welding, screwing, or the like. And a spout tube portion 12 extending upward from the joint portion 11 and a sealing cap 14 integrally formed via a thin wall portion 13 that can be broken off at the tip of the spout 12 a of the spout tube portion 12.
The sealing cap 14 is provided with a knob portion 14a that is extended outward so that the user can easily hold it with fingers when opening, and the inner surface of the knob portion 14a and the spout tube portion. 12 is connected to the outer peripheral surface via a breakable bridge 14b to provide durability that the thin-walled portion 13 is not easily broken due to careless handling of the break-out spout or impact during transportation. Yes.

  The sealing cap 14 projects outwardly from both outer sides of the coupling portion 14c formed integrally with the spout tube portion 12 via the annular thin portion 13, the top surface portion 14d covering the upper surface of the coupling portion 14c, and the top surface portion 14d. Further, a knob portion 14a extending further downward is provided so that an operation can be easily performed when the sealing cap 14 is gripped with fingers and folded and rotated in the circumferential direction.

Further, a bridge 14 b is disposed between the inner surface of the knob portion 14 a and the outer peripheral surface of the spout tube portion 11. In other words, before opening the break-up spout 10, the knob portion 14a and the spout tube portion 12 are locally connected via the weakening portion 15 via the bridge 14b.
Accordingly, the thinned portion 13 is prevented from being unintentionally opened by preventing the knob portion 14a of the break-up spout 10 before opening from being bent laterally with respect to the axial direction of the spout tube portion 11. So as to give strength.

The bridge 14b extends to both sides of a knob portion 14a provided to be extended to the outside of the sealing cap 14, and locally connects the inner side of the portion extending downward to the outer peripheral surface of the spout tube portion 12. At the time of opening, the weakening portion 15 which is a weakened portion connected to the outer peripheral surface of the spout tube portion 12 of the bridge 14b is broken by holding the knob 14a and rotating the sealing cap 14 in the circumferential direction. Thus, the bridge 14b is cut off from the outer peripheral surface of the spout tube portion 12, and the bridge 14b protruding toward the outer peripheral surface of the spout tube portion 12 is left on the inner surface of the knob portion 14a. That is, the bridge 14b is gradually thinned from the knob portion 14a side toward the spout tube portion 12 side.
The weakened portion 15 of the bridge 14b is connected to the outer peripheral surface of the spout tube portion 12 immediately above the portion corresponding to the lowest position of the inclined guide portion 12b before opening.

  An inclined guide portion 12b is provided close to both bridges 14b on the outer peripheral surface of the spout tube portion 12 where the bridge 14b is disposed via the weakening portion 15. The inclined guide portion 12b is a guide portion such as a groove for abutting the tips of both bridges 14b that remain on the inner surface of the knob portion 14a to rotate and guide the bridges 14b upward, and is sealed by the user. When the cap 14 is opened, the knob 14a is gripped with fingers and rotated in the circumferential direction to break the foldable thin portion 13 and the bridge 14b, and the broken bridge 14b along the inclined guide portion 12b. Guide upward.

Further, the inclined guide portion 12b is formed to be inclined on the outer peripheral surface of the spout tube portion 12 so as to rise in two circumferential directions, starting from a portion close to the lower portion of the connection position before the bridge 14b is cut off. Even when the knob portion 14a is rotated in any direction in the circumferential direction at the time of opening, the tip of the broken bridge 14b is guided upward along the inclined guide portion 12b, and the sealing cap 14 is spouted. It is made to isolate | separate from the spout 12a front-end | tip of the cylinder part 12. As shown in FIG.
Further, the bridge 14b guided upward can be retained above the inclined guide portion 12b, and the sealing cap 14 can be prevented from entering again into the spout 12a formed by breaking the thin portion 13.
In addition, although not shown in figure, the inclination guide part 12b may be provided in the vicinity of the bridge of one side so that only one bridge 14b may be guided.

Further, in the break-up spout 10 of the present embodiment, the inclined guide portion 12b has an inclined surface that extends upward from a position below the bridge 14b and from a position in the circumferential direction, in addition to the guide groove described above. Also good. In the case of the inclined surface, the shape is a slope with a width in the radial direction, and when the knob portion 14a is rotated in the circumferential direction, the lower part of the bridge 14b is guided in contact with the inclined surface.
By making the inclined guide portion 12b an inclined surface that restrains only the lower portion of the bridge 14b rather than a groove that sandwiches the bridge 14b, it becomes easier to separate the knob portion 14a from the spout tube portion 12.

Furthermore, the break-out spout 10 has a spout tube portion 12 with a spout 12a tip connected to a sealing cap 14 via an annular thin portion 13 and an outer peripheral surface of the spout tube portion 12 connected via a bridge 14b. Therefore, compared to the conventionally known cap-integrated pouring tool in which the cap and the spout are connected only by the annular thin wall portion, when an external force is inadvertently applied, etc. The durability of the sealing cap is excellent.
The thin-walled portion 13 is a weakened portion that connects the spout tube portion 12 and the sealing cap 14, maintains the sealed state between the spout tube portion 12 and the sealing cap 14, and is sealed to the spout tube portion 12. The cap 14 is fixed, the gripping portion 14a of the sealing cap 14 is grasped with fingers, and it is easily broken by performing a rotating opening operation. The sealing cap 14 is broken, and the spout 12a is formed in the spout tube portion. Can be formed.

The joint portion 11 has a boat-shaped cylindrical shape, and includes an upper flange 11b at a position further spaced from the lower flange 11a on the upper surface thereof, and is fixed after being inserted into an opening portion of a bag-like pouch container or the like. Examples of the fixing means include heat welding and use of an adhesive.
In the figure, upper, middle, and lower three-stage linear protrusions 11c are arranged on the mounting surface of the joint portion 11, thereby facilitating the joining of the joint portion 11 to the pouch container.

  A spout tube portion 12 is extended above the upper flange 11b of the joint portion 11, and the spout tube portion 12 is a drink that a user directly attaches after opening the sealing cap 14 from the broken spout 10. It becomes the attachment part of the mouth and the tube for extraction.

  Note that a plurality of step-shaped mounting portions 12 c that are tapered from the flange 11 b side toward the thin-walled portion 13 on the distal end side and have a step can be provided on the outer periphery of the spout tube portion 12. By providing such a step-shaped mounting portion 12c, it is possible to effectively prevent the tube mounted on the spout tube portion 12 in a state where the thin-walled portion 13 is broken and the sealing cap 14 is broken off from the container. The contents such as chemicals can be transferred without leaking outside.

Furthermore, the break-out spout 10 of the present embodiment may be provided with a screwing portion 12d for screwing a connector with a tube attached to the spout tube portion 12 with the sealing cap removed on the outer periphery of the spout tube portion 12. it can.
Thus, the tube can be securely attached to the spout tube portion 12 via the connector with a tube, and the contents can be prevented from leaking and used safely and hygienically.
