Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a packaging container with a spout.

(Prior Art) Conventionally, as shown in, for example, a packaging container B with a spout shown in FIG. 6, an upper portion of a container body 30 is closed with a canopy 31;
It is known that an opening 32 is formed in the canopy 31, a spout 33 made of synthetic resin is provided in the opening 32, and the contents are poured out from the spout 33.

When the contents are poured out, the opening 33 is
Slide 32 to protrude. As is well known, the packaging container B is provided with a bush 34 made of a synthetic resin on the periphery of the opening 32, while the lower end of the spout 33 has a width corresponding to the width of the portion in contact with the bush 34. A pair of upper and lower annular convex portions 35 and 36 are provided at intervals. The bush 34
Has a substantially U-shaped cross section, and is provided by engaging the inside of the groove on the outer periphery with the periphery of the opening 32. Further, a flat surface that contacts the spout body 33 is formed on the inner peripheral side of the bush.

When the spout body 33 is pulled up, first, the lower end of the bush 34 and the protrusion 35 above the spout body 33 abut each other, and when the spout body 33 is further pulled up, the protrusion 35 is pressed and deformed. While the bush 34 is also slightly deformed,
The spout body 33 slides smoothly. And the spout body
33 projects over the bush 34. Then, the lower convex portion 36 locks the lower end of the bush 34 and also locks the bush 34 by the two convex portions 35, 36 so as to sandwich the bush 34. Then, while keeping the container B and the spouting body 33 in the protruding state, the cap 37 is fitted to the tip of the spouting body 33 and closed and stored.

However, in such a packaging container B, the bush 34
After molding, the bush 34 is attached to the opening 32 formed in the canopy 31, so that the number of manufacturing steps is large, and there is a disadvantage that the manufacturing is troublesome.

In addition, the container B is configured such that the spout body 33
Since the sliding member 34 slides over the upper convex portion 35, the upper convex portion 35 in the projecting state of the spout 33 is easily released from the engagement with the bush 34 while the spout 33 is protruding.
For this reason, the holding force when the cap 37 is made to protrude from the spout body 33 is reduced, and there is a disadvantage that the cap 37 is pushed back inward again.

(Problem to be solved by the invention) By solving such inconvenience, the present invention makes it easy for the spout body to be pulled out from the opening and made to protrude, and moreover, to reliably maintain the protruding state of the drawn spout body. It is an object of the present invention to provide a packaging container with a spout that can be manufactured easily.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a container body and an opening formed therein. A canopy that is provided with a cylindrical synthetic resin spout having a cap detachably provided at an upper end thereof, wherein the top cover is provided with A second turn-up portion formed vertically along the top edge of the canopy from the first turn-up portion formed along the inner periphery of the opening continuously and perpendicularly to the canopy.
A cylindrical insertion portion in which the spout body is slidably inserted with a curl portion curling outward from the folded portion is integrally formed with the canopy, and the spout body includes A first convex portion that locks the lower end of the insertion portion around the lower end portion thereof to regulate the projecting dimension of the spout body, and a lower end of the insertion portion is locked to the first convex portion. A second convex portion which is locked to an upper end of the insertion portion and maintains the spout body in a protruding state; and the second convex portion is provided with a spout body facing the first convex portion. An upright surface that stands perpendicular to the outer surface and an inclined surface that gradually decreases in diameter and inclines upward from the distal end side of the upright surface are provided.

(Operation) By such means, when the contents of the container of the present invention are to be poured out, first, the spout body is slid onto the insertion portion to protrude. In the middle of the protrusion, the second convex portion of the spout comes into contact with the lower end of the insertion portion.

Then, the spout slides while the inclined surface provided on the second convex portion is in close contact with the insertion portion.
At this time, the insertion portion is moved by the curl portion to the second position.
It slides smoothly along the slope of the projection. Further, when the insertion portion gets over the second convex portion, the upright surface of the second convex portion locks the upper end of the insertion portion, and the spout body re-enters the container. To prevent. At the same time, the first convex portion of the spout is locked by the lower end of the insertion portion, and further projection is restricted.

Then, when storing the contents of the container, a cap is mounted on an upper end of the spout while keeping the spout protruding above the canopy. When wearing the cap,
Even if a pressing force is applied to the spout body from above, the upright surface of the second convex portion locks the upper end of the insertion portion as described above, so that the projecting state of the spout body Is securely held.

As described above, since the insertion portion 6 is formed continuously from the opening portion 4, it is not necessary to provide a bush as in the related art, and the number of manufacturing steps is reduced, and manufacturing is facilitated.

As shown in FIG. 2, the spout 3 comprises a cylindrical body 9 and a cap 10 which can be detachably mounted on the upper part of the body 9. Are connected by a flexible connecting portion 11.

As shown in FIG. 2, the trunk portion 9 of the spout body 3 has a communication portion 12 formed inside thereof and a communication portion 12 communicating with the inside of the container body 1, and a spout portion 13 is provided at an upper end of the communication portion 12. Have been.
At the boundary between the spout 13 and the communication portion 12, the communication portion 12
Is provided with an inner stopper 14 for closing the inner space. As will be described later, the inner plug 14 is broken through a breaking groove 15b by pulling up a knob 15a connected to the inner plug 14, and the communication portion 12
Becomes a communication state.

On the outer surface of the body 9 of the spout 3, a first convex portion formed in an annular shape integrally with the body 9 around the lower end of the body 9.
16 are provided. As shown in FIG. 2, the first convex portion
16 is formed with an inclined surface 17 whose diameter gradually decreases toward the lower end thereof.
When inserting the spout 3, the spout 3 can be smoothly mounted. Further, on the upper end side of the first convex portion 16 is formed an upright surface 18 which stands vertically with respect to the outer surface of the body portion 9.

Above the first convex portion 16 and above the second convex portion 16, a second convex portion 19 formed in an annular shape integrally with the body portion 9 is provided. As shown in FIG. 2, the second convex portion 19 is formed with an upright surface 20 which is opposed to the first convex portion 16 and rises vertically to the outer surface of the body portion 9. An inclined surface 21 is formed by gradually decreasing the diameter and inclining upward from the front end side of the surface 20.

In addition, when the packaging container A is in the closed state, as shown in FIGS. 1 and 2, the body 9 of the spout 3 is immersed inside the container main body 1 and the cap 10 is mounted thereon. Only the spout 13 is exposed on the canopy 2. At this time, the second bent part 7 formed at the lower end of the insertion part 6 is locked by the third convex part 22 provided on the upper part of the body part 9 of the spout body 3.

A method of using the packaging container A according to the present embodiment having the above configuration will be described.

First, as shown in FIG. 1, the cap 10 of the packaging container A filled with the contents and sealed is opened, and the cap 10 is gripped and the spout 3 is pulled up. At this time,
The second folded portion 7 of the insertion portion 6 of the opening 4 gets over the third convex portion 22 of the spout 3, and the body 9 of the spout 3 slides through the insertion portion 6.

Then, the spout 3 protrudes, and the insertion portion 6 gets over the second convex portion 19 of the spout 3. At this time, since the insertion portion 6 is slidably guided by the inclined surface 21 of the second convex portion 19, the work of pulling out the spout 3 can be performed smoothly.

The second folded portion 7 of the insertion portion 6 having passed over the second convex portion 19 is locked to the upright surface 18 of the first convex portion 16.
Thereby, the projection size of the spout body 3 is reliably regulated. At the same time, the upright surface 20 of the second convex portion 19 is locked to the first folded portion 5 of the opening.

Then, by pulling the knob 15a of the spout 3 upward, the inner plug 14 is removed via the breaking groove 15b.

As described above, as shown in FIG. 3, the spout 3 protrudes above the canopy 2, and the contents in the container A can be poured out.

Then, as shown in FIG. 4, the cap 10 is attached to the spout 13 so that the contents are stored. At this time, since the outer surface of the first folded portion 5 locks the upright surface 20 of the second convex portion 19 of the spout body 3, the spout body 3 is prevented from being pushed back, and the pouring body 3 is prevented from being pushed back. The projecting state of the outlet body 3 can be reliably maintained.

Further, in the present embodiment, the upper end of the insertion portion 6 is different from the prior art in which the bush 34 provided on the canopy 31 locks the lower convex portion 36 as in the conventional example shown in FIG. Since the first folded portion 5 is engaged with the second convex portion 19, a more secure engagement state is achieved. Therefore, even if a pressing force is applied to the spout body 3 downward when the cap 10 is put on, the projecting state of the spout body 3 can be reliably maintained.

As another embodiment of the present invention, as shown in FIG. 5, a cylindrical insertion vertically extending from the periphery of the canopy 23 to the upper portion of the canopy 23 via the first folded portion 25 is inserted into the opening 24 of the canopy 23. The attachment portion 26 may be formed. A second folded portion 27 is provided at the upper edge of the insertion portion 26.
The upper end of the insertion portion 26 is curled outward by the second folded portion 27. That is, the insertion portion 26 is provided so as to protrude above the canopy 23 with its upper end as the second folded portion 27 and its lower end as the first folded portion 25.

Since the spout body 3 to be inserted into the insertion portion 26 is the same as that of the above-described embodiment, the same reference numerals are used in the drawings. And the same.

As a result, when the spout 3 is projected, the insertion portion 26 gets over the second convex portion 19 of the spout 3.
At this time, the inclined portion 21 of the second convex portion 19 causes the insertion portion
Since the slide guide 26 is provided, the work of pulling out the spout body 3 can be performed smoothly.

The first folded portion 25 of the insertion portion 26 that has passed over the second convex portion 19 is locked to the upright surface 18 of the first convex portion 16.
Thereby, the projection size of the spout body 3 is reliably regulated. At the same time, the upright surface 20 of the second convex portion 19 is
Locked to 27.

Then, with the spout body 3 protruding, the spout portion
The cap 10 is put on the cap 13, and the contents are stored. At this time, since the second folded portion 27 locks the upright surface 20 of the second convex portion 19 of the spout body 3, the spout body 3
Can be reliably maintained in a protruding state without being pushed back.

(Effect of the Invention) As is clear from the above, since the insertion portion is formed integrally with the canopy, the canopy can be manufactured without attaching a bush or the like to the periphery of the opening of the canopy, and the number of manufacturing steps can be reduced. Can be.

In addition, the spout body can be easily pulled out from the opening by the inclined surface provided on the second convex portion of the spout body.

At this time, since the insertion portion has a curl portion formed along the peripheral edge of the distal end, sliding along the inclined surface of the second convex portion is performed smoothly, and the second convex portion is securely inserted. You can get over it.

Furthermore, since the insertion portion is sandwiched between the first convex portion and the second convex portion of the spout body, the projected state of the spout body can be reliably maintained. Since the upright surface of the second convex portion is locked to the upper end of the insertion portion, the holding force of the spout body in the protruding state is large, and the cap is mounted on the spout body in the protruding state. Even so, the protruding state can be reliably maintained.

Therefore, according to the present invention, it is easy to pull out the spout body from the opening and make it protrude.Moreover, it is ensured that the protruded state of the drawn spout body is maintained, and that the cap is capped in this protruding state. A packaging container with a spout can be provided which can be easily manufactured.
