Description

[Detailed description of the invention] (Industrial application field) The invention relates to a packaging container with a spout.
The present invention relates to a packaging container with a spout body in which an opening of a canopy into which a spout body is inserted is improved.

(Prior Art) Conventionally, for example, as shown in a packaging container B with a spout body shown in FIG. 8, the upper part of a container body 30 is closed with a canopy 31 having an opening 32 formed therein. There is a known one having a cylindrical spout body 33 made of synthetic resin for pouring out contents.

When the contents are poured out, the opening 33 is
Slide 32 to project from canopy 31. The packaging container B is
A bush 34 made of synthetic resin is provided on the periphery of the opening 32. The cross section of the bush 34 is formed in a substantially U-shape.
Is provided by being locked to the peripheral edge of. Further, a flat inner wall which slides in a state of being in contact with the spout 33 is formed on the inner peripheral side of the bush.

On the other hand, at the lower end of the spout 33, the bush 34
A pair of upper and lower annular locking portions 35 and 36 are provided at intervals corresponding to the width of the portion in contact with the cantilever, and the amount of protrusion when the spout body 33 protrudes above the canopy 31 is provided. Regulating.

When the spout 33 is pulled upward, the spout 33
When the bush 34 is slid in a state where the bush 34 is in contact with the outer wall thereof and is further pulled upward, the locking portions 35 and 36 of the spout body 33 lock the bush 34 from above and below. I do. As a result, the spout body 33 maintains its protruding state.

However, when projecting the spout body 33, the bush 34 deforms together with the upper locking portion 35 to
Since the vehicle gets over 35, it is easy to lock both locking portions 35 and 36, but the locking is easily released. For this reason, for example, there is a disadvantage that the holding force when the cap 37 is closed to the spout body 33 is reduced, and the spout body 33 is pushed back into the container body 30.

In view of this, the present applicant has previously proposed a packaging container with a spout that solves the above-mentioned disadvantages.

As shown in FIG. 9, the packaging container C has a cylindrical insertion portion 42 extending vertically from the periphery of the opening 39 of the canopy 38 to the inside of the container body 41 via the folded portion 40. I have. The body 43a of the spout 43 is slidably inserted into the insertion portion. At the lower end of the insertion portion 42, a curled portion 44 curled outward is formed to smoothly slide the spout 43.

On the other hand, a pair of upper and lower annular first and second locking portions 45 and 46 are provided at the lower end of the spouting body 43 at intervals corresponding to the width of the portion contacting the insertion portion 42. The second locking portion 46 is provided, and an upright surface 47 that stands upright with respect to the outer wall of the spout body 43 and a taper that gradually decreases in diameter and inclines upward from the distal end side of the upright surface 47. And an inclined surface 48.

With the above configuration of the packaging container C, the curl portion 44 at the lower end of the insertion portion 42 smoothly slides on the inclined surface 48 of the second locking portion 46 when the spout body 43 is pulled upward. And the insertion portion 42 is connected to the first and second
When sandwiched between the locking portions 45, 46, the upright surface 47 of the second locking portion 46 is locked to the folded portion 40 at the upper end of the insertion portion 42. Therefore, the projecting state of the spout 43 is reliably maintained.
As a result, the inconvenience is eliminated.

However, in order to pour out the contents x from the container body 41, the spouting body 43 is connected to the opening 39 of the canopy 38 of the container body 41.
In order to pull out and project more, the outer peripheral portion of the opening portion 39 is slid and protruded from the peripheral edge of the opening portion 39 through the folded portion 40 to the cylindrical insertion portion 42 extending perpendicularly to the interior direction of the container body 41.
It is difficult in manufacturing to completely adhere the insertion portion 42 and the spout 43 inserted into the insertion portion 42.

Therefore, when the spouting body 43 is pulled out from the opening 39 and made to protrude, the contents x attached to the outer wall of the body 43a of the spouting body 43 are completely scraped by the insertion portion 42. I can't take it.

Therefore, the content x is still attached to the outer wall of the body 43a of the projecting spout 43, and dust adheres to the content x, or the content x hangs down. There is an inconvenience that the canopy 38 and the vicinity of the opening 39 are soiled, which is not preferable in terms of food hygiene or aesthetics.

Furthermore, as shown in FIG. 10, even if the contents x adhering to the outer wall of the body 43a of the spouting body 43 are scraped off by the curl portion 44, no coating is applied. When the content x adheres to the curled portion 44 of the metal canopy 38, which is difficult to apply, the tip 49 of the curled portion 44 is corroded by the content x, and as the corrosion proceeds, the content x is eluted with the eluted metal. And the spout 43
Cannot be maintained in a protruding state, and there is a serious inconvenience that the canopy 38 is perforated.

(Problem to be Solved by the Invention) The present invention solves such a disadvantage, and when the spout is pulled out from the opening of the canopy and projected, the contents do not adhere to the outer wall of the body of the spout. It is an object of the present invention to provide a packaging container with a spout so that the contents are not contaminated by corrosion of metal and the function of the container is not impaired.

(Means for Solving the Problems) In order to achieve this object, the present invention provides a spout having a canopy made of a synthetic resin spout that is slidably inserted into a canopy through an opening thereof. In the body-equipped packaging container, a cylindrical insertion portion provided with a second folded portion in which an inner peripheral edge of the opening is vertically extended downward and a peripheral edge of the first folded portion is outwardly folded, and an outer wall and Close contact consisting of an engaging portion for covering and engaging the second folded portion and an annular convex portion connected to the engaging portion and abutting on the entire outer wall of the spout body at a position below the second folded portion. A member is provided.

(Operation) The spout is inserted into the insertion portion provided with the second folded portion of the opening of the canopy, and is provided so as to be able to protrude from the opening of the canopy. Thus, when the spout body is projected from the opening of the canopy, the outer wall of the spout body is guided by the second folded portion and slides smoothly on the inner wall of the insertion portion. The contact member covers an outer wall and a second folded portion of the insertion portion from below the first folded portion by the engagement portion, and has a content between the outer wall of the inserted portion and the second folded portion. Prevent intrusion.

The convex portion of the close contact member abuts on the entire outer wall of the spout body at a position below the second folded portion, whereby when projecting the spout body from the opening of the canopy, the convex portion is It slides while contacting the outer wall of the spout body to scrape off the contents adhering to the outer wall and return it into the container.
