Abstract

PROBLEM TO BE SOLVED: To provide a spout at a low cost, of which the intentional opening or opening by tampering can be determined at a glance. SOLUTION: This spout comprises a spout base 1 to be fixed to a bag 10 and a spout nape 2, both being integrally molded of a synthetic resin material with the aid of an annular thin-walled part 3. The spout nape 2 is provided with a lug 21, a stopper 22, a fitting part 23 whose outer shape is circular in a cross section, and a protrusion 24 in order named from the outer end side of the spout nape 2. Further, the stopper base 1 is provided with a cross- sectionally circular pouring path 12 which allows the fitting part 23 of the spout nape 2, which may be separated, to fit on the outer end side thereof while the pouring path 12 is provided with an insertion groove 13 through which the protrusion 24 of the stopper nape 2 can be axially put into and taken out, and a step 14 with which the protrusion 24 of the stopper nape 2 can be selectively engaged in a circumferential direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a spout of a bag for enclosing and distributing juice and other drinks, paste-like drinks, liquid detergents and the like.

[0002]

2. Description of the Related Art As a conventional spout, for example, Japanese Utility Model Publication No. 5
JP-A-3-15659 can be mentioned. In such a spout, a separate lid member is screwed or pivoted to the pouring neck so that the bag can be opened and closed during the use process.

[0003]

However, in the above-mentioned conventional spout with a lid, the spout neck and the lid member must be separately formed, which increases the cost and increases the cost in the distribution process. As a safety measure, there is an inconvenience in that the bag must be entirely covered with a transparent bag in order to eliminate the risk of foreign matter being mixed in through the spout.

The spout of the bag according to the present invention solves the above-mentioned problems, reduces the cost, and, when the spout is opened during the distribution process, allows the spout to be seen only by looking at it. It has been proposed as a purpose.

[0005]

In order to achieve the above object, a spout of a bag according to the present invention is obtained by synthesizing a spout base and a spout top fixed to the bag via an intermediate annular thin portion. The spout top shall be gripped in order from the outer end, a stopper, a fitting having a circular cross-sectional profile, and at least one protrusion protruding in the radial direction of the fitting. Being provided; the spout top is cut off at a thinner portion than the spout base when the contents of the bag are poured out; and the spout base is fitted at the outer end side of the spout top. A spout top having a circular cross section into which the spout top is fitted, and an insertion groove into which the protrusion of the spout top can be inserted and removed in the axial direction and a protrusion of the spout top in the circumferential direction are selectively provided. Stage to be engaged with It is provided with a; and spout Itadakitai is configured condition that is used as a stopper fitted to the spout base in the process using the contents of the bag.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings. 1 to 5,
Reference numeral 10 denotes a flexible bag made of a synthetic resin material or the like, in which contents (not shown) such as juice and other beverages, pasty foods, liquid detergents, and the like are sealed and provided for distribution.

The spout according to the present invention comprises a spout base 1 and a spout top 2 which are fixed to a bag body 10 by an adhesive means or a welding means. It is molded integrally with the material.

The spout top 2 is provided with a knob 21, a stopper 22 having a flange shape, a hollow or solid fitting portion 23 having a circular cross section, and a fitting portion 23 having a circular cross section. And at least one (two in the figure) projections 24 protruding in the radial direction.

Each of the projections 24 has a spout top 2 separated from the spout passage 12 for the spout base 1 as described later.
It is preferable to provide an inclined portion 24a in order to make the protrusion 24 more easily engage with the step portion 14 when sealing.

When the contents of the bag body 10 are poured out, the spout top 2 is cut off with a finger or the like at the thin portion 3 of the spout base 1 formed integrally with the spout top 2 with fingers. By doing so.

The spout base 1 has a finned mounting portion 11 fixed to the inner surface of the bag body 10 on the inner end side, and a fitting portion 23 of the separated spout top 2 on the outer end side. A circular cross-section spout 12 fitted with no gap
, Respectively.

When the bag 10 is not used, it goes without saying that the outer end of the spouting channel 12 communicated with the inside of the bag 10 is sealed by the integral spout top 2 via the thin portion 3.

As shown in FIGS. 4 and 5, the spout base 2 in the spout top 2 in a separated state is inserted in the spout passage 12 of the spout base 1 in the axial direction (the direction in which the contents are poured out). The protrusion 24 of the fitting portion 23 has an insertion groove 13 into which the protrusion 24 can be inserted and withdrawn, and the protrusion 24 of the fitting portion 23 of the spout top 2 which is separated in the circumferential direction in the pouring channel 12 is selectively provided. Is provided with a stepped portion 14 to be engaged with.

In FIG. 1 to FIG.
2 is a cylindrical portion constituting the outside, 16 is an upper surface plate portion of the mounting portion 11, and 17 is a mounting portion 11 for reducing the weight of the spout substrate 1.
It is a cavity provided in.

The spout of the bag according to the present invention is a bag 1
In the process of distribution, the spout top 2 is integrated with the spout base 1 via the thin portion 3, and the contents are sealed to the outside.

When the contents of the bag 10 are used at home or the like, as shown in FIGS. 5 and 6, the spout top 2 is separated from the spout base 1 by a finger or the like at the thin portion 3, and the spout base 1 is removed. The contents are squeezed out from the pouring path 12 and used.

When the contents remain in the bag 10,
The spout top 2 separated from the spout base 1 is used as a fitting plug.

When the spout top 2 is used as a stopper (see FIG. 6), the knob 21 is grasped with fingers and the projection 24 of the spout top 2 is inserted into the insertion groove 1 of the spout channel 12 in the spout base 1.
Then, the fitting portion 23 of the spout top 2 is sufficiently pushed into the spout channel 12 of the spout base 1.

The pushing depth of the spout top 2 is limited by the stopper 22 abutting on the mouth of the spout channel 12 in the stopper base 1.

Therefore, the stopper top 2 is attached to the spout base 1.
On the other hand, when the spout is rotated about 90 ° clockwise, as shown in FIG. 7, the projection 24 of the spout top 2 engages with the step 14 of the spout base 1, so that the internal pressure is applied to the spout top 2. Even if hooked, the spout top 2 is prevented from coming off.

The spout top 2 is detachably attached to the spout base 1 as a plug in a state where the spout top 2 does not easily come out even if it is pulled out. In addition,
To remove the spout top 2, the operation may be reversed.

[0022]

According to the spout of the bag of the present invention described above, the spout base and the spout top can be formed integrally with a synthetic resin material including a thin portion, so that the processing cost can be reduced. Can be measured.

Further, since the intentional or mischievous opening with respect to the spout can be determined at a glance, safety can be ensured without putting on a transparent safety bag.

Furthermore, since the spout top that has been separated can be used as a stopper as it is, it is easy to use.
And various other effects.
