DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, the configuration of the container of the present invention will be described. 1 shown in FIG.
This is a container body formed into a bag-like shape capable of sealing an object such as a beverage therein by heat-sealing the side edges and upper and lower edges of a, 1b.

The material of the sheet body of the container body 1 is as follows.
A heat-sealing resin such as polyethylene or polypropylene is formed on the inner surface of a film in which a polyester film such as polyethylene terephthalate, a polyamide film, etc. and a gas barrier film such as an aluminum foil, an ethylene vinyl alcohol copolymer film, or a film on which an inorganic substance is deposited are laminated. Although a laminated film having a layer formed thereon can be used, the present invention is not limited to this. The inner surface side is made of any material such as other synthetic resin film and can be heat-sealed, and the object to be stored, such as a beverage, is contained therein. Anything that can be stored may be used.

Reference numeral 2 denotes a mouth member formed of a synthetic resin of a material that can be heat-sealed with the sheet body of the container body 1;
The mouth member 2 is sandwiched between the front and rear sheet pieces 1a and 1b at the upper edge of the container body 1, and the front and rear sheet pieces 1a and 1b are held therebetween.
A mounting portion 4 which is heat-sealed with the inner surface of the container, a pouring portion 3 having a spout portion 3a formed at the center of the mounting portion 4 and capable of taking out an object to be stored from the inside of the container body 1; Department
4 has a rod-like portion 5 extending downward, and the upper portion of the pouring portion 3 has a structure in which a screw-type lid 7 is detachable (not shown). You.

As shown in FIG. 3A, the mounting portion 4 is formed such that the width d in the thickness direction of the container body 1 is smaller than the outer diameter d 'of the upper part of the pouring portion 3, and as shown in FIG. It is formed in a flat shape.

The pouring opening 3a of the pouring section 3 is open in a perfect circular shape at the upper part of the pouring section 3, but becomes thinner in the thickness direction as it goes down, like the outer shape of the pouring section 3. On the other hand,
As shown in FIG. 3 (b), the opening is formed in a flat opening shape extending in the width direction. For this reason, the opening 4a and the spout 3a of the mounting portion 4 are formed so that the areas of the arbitrary horizontal cut surfaces are substantially equal.

The lower end of the spout 3a of the pouring section 3 and the upper end of the opening 4a of the mounting section 4 communicate with each other.
Can be taken out through the opening 4a of the mounting portion 4 and the spout 3a. The upper end of the opening 4a of the mounting portion 4 is formed so as to match the shape and size of the lower end of the spout 3a.

The rod-shaped portion 5 is formed in an N-shape in cross section, and its upper end is integrally formed so as to connect the inside of the opening 4a of the mounting portion 4 in the thickness direction. As shown, it is formed as a reinforcement 6.

Next, a case where the container 10 having the above-described configuration is manufactured will be described. First, a pair of sheet bodies
The side and bottom edges of 1a and 1b are heat sealed to form a bag with an open top edge.

Then, the mouth member 2 is inserted into the upper edge of the container body 1, and the side peripheral surface of the mounting portion 4 and the inside of the front and rear sheet members 1a and 1b of the container body 1 are heat-sealed. At the same time as sealing the upper edge of the main body 1, the mouth member 2 is attached to the container main body 1. If the mounting portion 4 of the mouth member 2 is heated in advance during the heat sealing, the heat sealing can be performed more efficiently.

At the time of this heat sealing, the upper end edge of the container body 1 is sealed while being pressed from the outside by a heating and pressing means such as a heat bar. As described above, the mounting portion 4 is formed in a thin flat shape and has a peripheral shape. Since the curve of the surface is gentle, it is easy to press, and at the same time, the pressing force can be applied substantially uniformly over the entire surface.

Since the upper end of the rod 5 is attached as a reinforcing member 6 in the opening 4a of the attachment 4,
Even when strongly pressed by a heat seal bar or the like, since the mounting portion 4 is supported from the inside of the opening 4a by the reinforcing member 6, there is no possibility that the mounting portion 4 is deformed or damaged when pressed, and a strong pressing force is applied. It can be reliably sealed.

In particular, since the mounting portion 4 is formed flat as described above, the thickness of the side wall is reduced, and the side wall is easily deformed and damaged by the pressing force at the time of heat sealing. However, the reinforcing member 6 is provided in the opening 4a. This eliminates the possibility of such deformation and damage.

After the container body 1 is filled with the objects to be stored, the lid 7 is mounted on the upper part of the spout 3, but the upper part of the spout 3 is different from the lower part in the shape of a perfect circle. Since it is formed in a shape, it is easy to insert a filling nozzle for filling an object to be stored, and a screw-type lid can be attached.

In order to take out the contents to be stored, for example, a beverage, from the container 10, the lid 7 is removed and the product is poured from the spout 3 a or the mouth is directly placed on the upper part of the pouring section 3. Even if the attachment portion 4 has a flat shape, the opening 4a has the same area as the spout 3a, so that it is not difficult to take out the stored object. Further, since the opening 4a of the mounting portion 4 has a shape that expands in the width direction of the flat container body 1, the container body
The stored items are easy to take out from both side corners of 1 and the stored items are unlikely to remain.

Further, since the rod-shaped body 5 is provided below the mouth member 2 so as to extend in the up-down direction of the container body 1, it is possible to reduce the number of items to be stored such as beverages in the container body 1 when the remaining amount becomes small. It is possible to prevent the inner surfaces of both sheet bodies 1a and 1b of the container body 1 from coming into close contact with each other due to suction from the outlet 3a, thereby making it difficult to remove an object to be stored. Can be taken out reliably.

In the above-described embodiment, the outer shape of the pouring portion 3 is formed in a perfect circular shape at the upper portion, and becomes thinner in the thickness direction of the container body 1 and expands in the width direction as it goes down to the mounting portion 4 side. However, it is not a condition that the pouring portion 3 is formed in such a shape.

For example, as shown in FIGS. 5A to 5D, the outer shape of the pouring portion 3 is formed in a cylindrical shape having the same diameter in the upper and lower directions, and the pouring port is formed.
An elliptical opening having the same shape as the shape of 3a in the vertical direction may be formed. In this case, since the opening 4a of the mounting portion 4 is also an elliptical shape having the same shape, the opening 4a of the mounting portion 4 is
An opening having the same shape is continuously formed up to 4a.

Further, in the above-described embodiment, the section N
FIG. 5 shows that the bar-shaped body 5 is extended below the mounting portion 4.
As shown in (a), a rod-shaped body 5 composed of two plate-like bodies,
It can be formed in a rod-like body of any shape such as a columnar one. In short, any rod-shaped member may be used as long as it extends vertically in the container body 1 so that the sheets 1a and 1b of the container body 1 do not come into close contact with each other when the items to be stored in the container body 1 are low.

As shown in FIGS. 6A to 6D, the rod 5 is formed in a pipe shape having an opening 5a communicating with the opening 4a of the mounting portion 4. It may be used as a straw for sucking up beverages and the like inside the container body 1 from the outlet 3a.

In this case, FIG.
It is preferable to attach a separate or integrally formed reinforcing member 6 as shown in (c) from the viewpoint of preventing deformation and breakage of the attachment portion during heat sealing.

Further, in the above-described embodiment, a preferred example in which the horizontal cross-sectional area of the spout 3a and the opening 4a at an arbitrary position are substantially equal has been described, but the spout 3a and the opening 4a are not limited to this. It is not something to be done. Furthermore, although illustration and the like are omitted, a groove or the like for a screw cap is formed on the outer surface of the pouring section 3, and one or several flanges or the like may be formed.

Further, the specific shape of the container body 1 may be a self-standing bag shape having gussets formed on both sides or a bottom portion, or may be formed from a tubular film. Not something.

[0035]

As described above, according to the present invention, in a simple container made of a sheet member, the attachment to the mouth member is strengthened,
In addition, the occurrence of sealing failure can be reliably prevented, and the detachable lid can be easily attached to the mouth member. Further, when the reinforcing member is provided in the opening, the opening member is not deformed or damaged even if a strong pressure is applied at the time of heat sealing, so that the operation of securely attaching the opening member can be easily performed. In the case where there is a rod-like body extending downward, even if the remaining amount of the object to be stored in the container is small, it can be easily taken out, and the amount of the object to be stored can be reduced.
