Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a container with a pouring hole in which a pouring hole is covered with a sealing member that also serves as a tab.

(Prior Art) A conventional paper container of this type is simply a sealing member that also serves as a tab is attached to the pouring hole, and no consideration is given to running out of the liquid when pouring out the content liquid. It wasn't even done.

(Problems to be solved by the invention) In using the above-described paper container, when using it, the sealing member that also serves as a tab that seals the pouring hole is peeled off, and the container body is tilted to remove the content liquid. When pouring out, the pouring content liquid is not well drained and easily propagates along the container body surface, and when pouring into the receiving container, the content liquid may be wasted and is not hygienic. It was

The present invention has been devised in view of such a point, and an object thereof is to attach a sealing member that also serves as a tab to a pouring hole formed in an inclined roof portion of a container body. At the pouring outlet, when the content liquid is poured out, the content liquid is well drained so as not to be transmitted along the container body surface.

(Means for Solving the Problem) In order to achieve the above object, in the present invention, the problem is solved by pressing the lower end of the lower end of the pouring hole to make a recess.

That is, in the present invention, in the case where the outer surface sealing portion groove also serving as the tab is attached to the pouring hole provided in the roof portion of the container body, the surface of the inclined roof portion and the surface of the body portion are By pressing the central portion of the ridgeline, a fold line in which the pressing portion is recessed so that the lower end portion of the pouring hole projects outward is provided across the inclined roof portion and the body portion.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In the present invention, when the blank plate (A ') before assembling the container body (A), the spout is formed with a spout hole, assembling as the container body, and forming a fold line for a recessed portion by pressing. And are doing.

The blank plate (A ') is made of polyethylene / paper / polyethylene and has a spout hole (2) at the center of the sloping roof part (1) at a position about 1/3 to 1/2 from the lower edge. ) Is drilled. The pouring hole (2) has an openable lid portion (4) having a fold line (3) at the upper edge. A small opening (6) is formed below the lower edge (5) of the lid portion (4).

The pouring hole (2) is an outer surface sealing member (a) which also serves as a tab and has an aluminum foil coated with polyethylene from the outer surface, and an inner surface sealing member (b) of a polyethylene film from the inner surface.
Are covered and adhered respectively. These sealing members (a) and (b) are lightly adhered to the blank plate (A '), but are strongly bonded to each other through the small opening (6) of the pouring hole (2). It is glued.

The lower end apex (7) of the pouring hole (2) forms an acute angle, and both ends (10) of the ridgeline (9) where the respective surfaces of the roof (1) and the trunk (8) intersect. ), (10), between the lower end apex (7) and the point (11) on the center line passing through it, and both ends (10), (10) of the ridge (9) A polygonal line (12) is formed.

Reference numeral (13) is a fold line for assembling the container body (A) from the blank plate (A ').

The blank plate (A ′) thus provided with the pouring hole (2) is applied to a series of filling and sealing devices in a state of being formed into a rectangular tube shape and pressed into a flat shape, and is assembled by folding from the fold line (13). The container body (A) is filled with the content liquid and sealed to form a product.

To pour out the content liquid from the product in which the content liquid is filled and sealed, pull the knob (14) of the outer surface sealing member (a) that also functions as a dove and pull it to seal the outer surface sealing member (a) and the inner surface. With the member (b), the lid (4) is sandwiched and the small openings (6) are strongly welded to each other, so that the member (b) is cut off from the lower end apex (7) of the pouring hole (2) without peeling. Begins and the cut proceeds along the hole edge to the fold line (3).

Here, the lid portion (4) is opened and the pouring hole (2) is fully opened.

Next, the container body (A) is tilted to pour out the content liquid. At the time of pouring, the ridgeline (9) of the roof part (1) and the trunk part (8) intersects each other. When the central part is pressed, it folds from the fold line (12), the inside of the rhombic fold line (12) is recessed, the lower end apex (7) of the pouring hole (2) projects, and the lower part thereof is a sloping roof ) Keeping the angle to the surface, the container body (A)
It does not flow down along the surface because it is well drained.

When the outer surface sealing member (a) that also serves as a tab is returned to its original position, the lid portion (A) maintains its position due to friction with the hole edge.

As the pouring hole, there is another pouring hole as shown in FIG. The pouring hole (2 ') shown in FIG. 5 is different from the pouring hole (2') shown in FIG. 2 at the lower end of the pouring hole (2 '). ′) Has been formed. This is because when the pressing portion by the broken line (13) below it is pressed during the pouring of the content liquid, the protruding portion (7 ') is projected outward, and the outflow of the content liquid is good.

Further, the pouring hole may be simply a hole without a lid.

(Effects of the Invention) The present invention has only a fold line that is recessed inward by pressing below the lower end of the pouring hole sealed by a sealing member that also serves as a tab. By pressing the central part of the ridgeline intersecting the surface of the body and the surface of the body, the lower part of the lower end of the pouring hole is recessed inward, and the surface of the roof part where the pouring hole is provided is pressed. Since the angle with respect to the container body is maintained, it is not transmitted along the container body surface, and it is not necessary to wipe the container body surface even after pouring, which is hygienic.
