DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a spout in a synthetic resin film bag having a spout.

[0002]

[Technical Background] Containers filled with liquid, gel or similar substances, which are the main products for sale, are mainly solid, tangible containers molded of glass, synthetic resin or other substances. As part of the objectives of reducing waste and reducing the amount of raw materials used from the perspective of environmental protection and effective use of resources, some containers have been changing from solid to flexible bags. is there.

[0003]

2. Description of the Related Art In place of a conventional solid fixed container, a generalized flexible bag-shaped container having a rectangular upper portion has been proposed.
A pouring opening is formed obliquely inside one corner where the vertical side and the upper side are joined, and the pouring path is formed by cutting the corner where the pouring opening is formed when pouring out the filler. Some are configured so that they can be opened.

[0004]

Generally, such a container has a bottom-closed elliptical shape so that it can be placed upright when the contents are filled. In most cases, the upper end is formed in a rectangular shape with one end in a rectangular shape at the upper end.

[0005] In this type of bag, as a means for forming a spout provided in one upper corner, the corner is cut to open a pouring path. The opening end position is inward from the vertical side of the bag,
At the stage of pouring out the contents, the discharge route of the pouring flow is not determined, and the to-be-poured material is dropped on the palm grasping the bag or on the outer surface of the bag.

A person who has experienced such a situation gives due care to the next time, but in any case, it must be done with great care in pouring out to a desired place.

Further, there is no problem in pouring out all the contents at once immediately after opening and discarding the empty bag, but when pouring out the filling in the bag container and preserving the remaining amount, When residual liquid that cannot be completely drained adheres to the edge of the opening of the spout, causing dust or the like to adhere due to contact with the outside air, and causing inconvenience such as rot following the solidification or solidification due to drying. There is.

Accordingly, a first object of the present invention is to provide a synthetic resin film bag which is easy to use for pouring out contents.

A second object of the present invention is to provide the above bag in which a spout is formed so that the spout is well drained when the spout is cut.

[0010] A third object of the present invention is to provide the above bag in which a cutting line for forming a spout does not deviate from a predetermined position.

[0011]

According to the present invention, as a means for achieving the above-mentioned object, a first invention is to narrow a pouring path at one corner at an upper end, and
A synthetic resin bag that seals the tip of the pouring path, wherein a pouring path that is narrower and continuous from an upper corner of a filling main part to be filled with contents is outward from the filling part, and is oblique.
A bag material on the front and back is welded so as to be directed upward so as to form a pour-out part by welding so as to form a sealing at the tip and a path wall, and the pour-out part is at the upper end of the bag body and has a vertical side.
It is formed so as to protrude and beak-shaped.

[0012] The second invention is a bag, which protrudes from a vertical side.
A cutting instruction is provided at a position intersecting with the pouring path in the pouring section formed so as to protrude so as to form a beak, and a path having a small diameter that widens the lower side of the pouring path at the position intersecting with the cutting instruction is provided. It is recessed so as to cut into the wall.

[0013]

[0014]

According to the present invention, when the material to be filled is poured out of the sealed and sealed bag container, cutting is performed based on the cutting instruction displayed on the beak-shaped pouring portion of the bag container. The delivery path is opened. Since the path wall forming this pouring path protrudes beak-like from directly below the pouring section,
It can be inserted into the opening of the container to which the substance to be poured is transferred, avoiding the release in an unintended direction, and accurately releasing an arbitrary set amount.

In the pouring section, a small-diameter recess for enlarging the inner diameter of the path is formed in the lower side of the pouring path corresponding to the cutting instruction line so as to bite into the path wall. When the position is cut, the recess is enlarged stepwise so that at the end of the pouring, the pouring substance can be dropped without remaining in the pouring opening. That is, since the liquid drainage is improved, the dripping phenomenon of the residual substance over time after the pouring operation is completed is prevented.

Further, the display of the cutting instruction is provided such that the tip is sealed and an intermediate portion near the tip of the pouring path that is directed obliquely upward is intersected with the pouring path. It is provided in a state parallel to the vertical center line of the container, and since the display by printing or the cutting instruction position is in the middle of the beak shape, the path wall forming the pouring path according to the line drawing by the previous printing is formed. The upper side and the lower side are provided with cuts or V-shaped cuts that match the line drawing so that hand tearing can be opened.

In order to enable the opening operation by such a hand crack, the synthetic molecular film of the material constituting the bag main part of the bag container has its composition molecular arrangement already determined in the manufacturing process. Since this compositional molecular arrangement is produced in a close relationship with the production direction to make the synthetic resin film long, the compositional molecular arrangement matches the longitudinal direction of the bag container described above. Need to be produced. Further, in the case where the opening means of such a hand tear is not set and the opening means using a blade is employed, there is no need to consider the compositional molecular arrangement of the material.

As described above, the cutting instruction is printed by a line or a chain line on both the front and back sides of the bag container. In the case of cutting by hand tearing, both sides of the cutting instruction so that the cutting line does not deviate from a desired position. A raised ridge is provided to prevent derailing cutting.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
Is formed by folding or laminating a synthetic resin film of a material into two parts and welding the main filling part 1 including the pour-out part 4 to the periphery by welding 8.
However, since the entire circumference is sealed after the contents are filled, any one of the entire circumferences is left with a non-welded portion as the contents filling port during bag making. .

The bag A of the present invention has a main shape in the form of a vertically elongated two-sided rectangle except for the bottom portion, most of which is the filling main portion 1, and one of the upper corner portions is a pouring portion. 4.

[0021] Pour out portion 4 is formed by the path 2 poured branched from a portion has a filling main portion 1, path 2 poured the can path extending around the weld 8 points to form a filled main part 1 The tip is also closed by the wall 3 and diagonally upward
It is formed with a slant shape condition to direct.

The pouring portion 4 is formed in a beak-like shape 5 and has a plurality of embodiments.

One example is the case where the base of the beak 5 is located at one side of the bag A, that is, the upper end of one vertical side 9 as shown in FIG. 7, and the pouring portion 4 as shown in FIG. Is formed at the base of the lower side of the beak-shaped part 5 forming the base and the recessed part 11 having the base as the upper end in some cases.

The recessed part 11 is the pouring part 4 before cutting.
When the tip end is positioned at the same position as one side of the bag A, that is, one of the vertical sides 9, the pouring portion 4 is formed by partitioning the recessed portion 11.
Is a substantially inverted U-shape rather than an inverted V-shape. When the opening frontage is enlarged, the recessed portion 11 is used as the bag grip portion 10.

Further, as shown in FIGS. 9 and 10, a recessed portion 11 is also formed on the upper side of the bag body A at a position close to the pouring portion 4 to form a beak portion 5 which is clearly shaped. Sometimes.

In the pouring portion 4 protruding and formed in such a beak shape 5, a printing means is exposed on an outer surface of a portion crossing the oblique pouring path 2 whose tip is sealed by welding 8. A cutting instruction 6, such as a vertical line or a vertical line or a chain line that is approximately perpendicular, is provided.

As described above, the small-diameter concave portion 7 that cuts into the path wall 3 below the lower side 2a of the pouring path 2 that intersects the cutting instruction 6 with the display location is formed to form a liquid drainage improving portion. That is, when cutting is performed based on the cutting instruction 6 and the pouring path 2 is opened, the inner diameter of the pouring path 2 has a shape in which the lower edge is sharply enlarged near the opening and the opening edge is formed. In such a manner that no residual droplets are observed.

Further, in the above cutting instruction 6 at the pouring section 4, a cut or a V-shaped cut may be provided from the outer periphery of the welded portion 8 so as to be convenient for the hand crack opening means. The opening assisting means is a conventionally known means. However, in the present invention, since the above-described recess 7 is provided at a position corresponding to the position of the cutting instruction 6, the opening assisting means is used for hand crack opening work. Also, since seven recesses must be made to appear by the opening operation, it is necessary to match the hand-cutting direction with the compositional molecular arrangement of the synthetic resin film constituting the bag A.

Furthermore, in order to form a cutting opening in accordance with the cutting instruction 6 at the time of opening by the above-mentioned hand tear cutting operation, FIGS. It is desirable that the protruding protrusion 12 is provided along the projection so that the cutting line does not come off from the protruding protrusion 12.

[0030]

As described above, according to the present invention, since the pour-out portion for pouring out the contents is formed in a beak-like shape, it can be inserted into the opening of the empty container for transferring the contents and can be poured out. Can be prevented from leaking out of the injection container.

Further, even if the opposite part to be transferred is located at a remote position, since the pouring outlet has a beak shape having a pouring path, a release mark can be set, thereby preventing pouring and discharging in an unintended direction. can do.

Further, when it is desired to leave the contents filled in the bag A other than discharging the entire amount, when the discharging of the desired amount is completed,
This has the effect of improving the liquid drainage that does not leave residual droplets at the opening of the pouring port.

Furthermore, since the cutting instruction portion has raised protrusions protruding from both sides thereof, even if the opening operation is performed by hand tearing, the cutting path does not deviate from the cutting instruction and the desired cutting can be accurately performed. It can be cut out.
