Description

The present invention relates to a paper packaging container.

For containers filled with viscous, semi-fluid or solidified foods such as semi-solid and solidified foods such as tofu and jelly, for example, a web-like packaging laminate material having a predetermined crease line is formed into a tube shape, Vertically sealed in the line direction, filled with liquid food in the tube-shaped packaging material, sealed with a transverse seal in the transverse direction at predetermined intervals, cut in the middle of the transverse seal zone to obtain a pillow-shaped preform, and the crease line The flaps and fins including the transverse seal zone formed by folding along the container are joined to the container top wall, container side wall and container bottom to obtain the final container, and the liquid food in the container is solidified and solidified to obtain the product. obtain.

FIG. 3 is a schematic perspective view showing an example of a packaging and filling apparatus. The web-shaped packaging laminate material 1 is loaded into a packaging and filling apparatus in a reel state. The packaging laminate material 1 includes a paper base material and a flexible laminate in which polyethylene resin is laminated on both sides of the paper base material, and an aluminum foil or gas barrier is provided between the paper base material and the film as necessary. A barrier layer made of an adhesive resin or the like is formed, and exterior printing is performed in advance on a portion corresponding to the surface of the packaging container 14.

The fed packaging laminate material 1 is continuously conveyed by the feeding device of the conveying means, is sent to the strip joining device 3 through a bending roller, a damper roller, and the like, and one edge portion of the packaging laminated material 1 is fed by the strip joining device. , The strip 2 is joined continuously, joining the next strip with a seam.

As for the packaging laminated material 1, the pull tab is joined by the pull tab joining apparatus as needed. The packaging laminated material 1 is sent to the sterilization tank 4 and sterilized with a sterilization liquid such as hydrogen peroxide in the sterilization tank 4. The packaging laminate material 1 is sent to an air knife 5, dried by the air knife 5, and then fed into a sterilization chamber 40 that guarantees filling the tube-shaped packaging material with liquid food in a sterile atmosphere. The packaging laminated material 1 is gradually deformed by the molding ring 6 and other molding rings to form a tube shape.
The tubular packaging laminate material 1 is preheated by hot air from the preheating means 8 of the vertical sealing device and sealed in the longitudinal direction, and fluid food is filled into the tubular packaging laminate material 1 from the lower end of the filling pipe 7. The

Next, the vertical seal element 8 forms the vertical seal portions 26 on both edges of the tube, and the tube 1 is sandwiched by the horizontal seal device 10 while being sent downward by a length corresponding to one packaging container, Two transverse seal zones 23 are formed by transverse sealing in the transverse direction, and simultaneously formed into a pillow-shaped preform 13 at the same time. Then, it is cut by a knife or the like and cut into individual pillow-shaped preforms 13, and the upper and lower flaps of the pillow-shaped preforms cut by the final molding device 15 are bent and molded into the final packaging filling container 14. .
The packaging and filling container 14 is continuously translated and conveyed by a conveying means such as a belt conveyor, and is packed by a certain quantity through a straw applicator or the like that sticks the straw to the container wall. The liquid food in the container is solidified and solidified in the container to obtain a product.

A mode in which the pillow-shaped preform 13 is folded by the final molding apparatus is shown in FIG. The pillow-shaped preform 13 is sealed with a vertical seal portion 26 and two upper and lower horizontal seal zones 23, and has a side wall 22 divided by a crease line. (See Fig. 4 (A))
As shown in FIG. 4 (B), the body portion of the pillow-shaped preform is formed in a rectangular parallelepiped shape along the crease line, and fins 23 and flaps 24 of the lateral seal band are provided at the edge of the ridge side. It is formed to stand upright from the wall. The fins 23 in the lateral seal zone stand upright from the bottom surface 20 and the top surface 21, and the flap 24 communicates integrally with the container wall via the edge 25.
Next, as shown in FIG. 4 (C), the fins 23 in the lateral seal zone are folded into the bottom surface 20 (shown upside down as a container in FIG. 4) and the top surface 21, and then the flap is centered on the edge. , The container top side flap 24 is folded into the side wall 22, and the container bottom side flap 24 is folded into the bottom surface 20.
FIG. 2 shows an external perspective view of a brick-type liquid food-filled paper container. The container has folded side seal zone fins 23, flaps 24, bottom and top walls and container sidewalls. The fins 23 are folded into the container top wall surface 22a side opposite to the vertical seal portion 26. Further, the flap 24 is folded into the side wall via the ridge.

Use a paper container filled with semi-solid or coagulated food such as tofu or jelly by cutting or tearing one end of the vessel wall with scissors etc. and taking out the tofu or jelly from the wide open opening Is done.

JP 2002-307575 A

When removing tofu or jelly from a paper container, one end of the container is cut with scissors or the like to form an opening, but since tofu and jelly are not fluid, there is no fluidity between the inner surface of the container and the contents. There is an inconvenience that air does not enter after opening and the contents cannot be easily taken out.
An object of this invention is to provide the packaging container which solves the problem of a packaging container and eliminates the said inconvenience.

The paper packaging container of the present invention that solves this problem forms a horizontal seal zone and a vertical seal zone by a vertical seal and a horizontal seal from a web-like packaging laminate material having a crease line, and folds along the crease line. A food-filled container that obtains a product by solidifying and coagulating liquid food in the container by joining flaps and fins including lateral seal zones formed by the above to the container top wall, container side wall, and container bottom to obtain a final rectangular container Because
This container has an opening for taking out filled food formed by cutting one end of the container, and has an easily breakable portion at the other end opposite to the opening, and the easily broken portion is broken when the filled food is taken out. This makes it easy to take out the filled food.

According to the present invention described above, the following functions are exhibited and advantageous effects are obtained.
The paper packaging container according to the present invention is formed by forming a horizontal sealing zone and a vertical sealing zone from a web-like packaging laminate material having a crease line by means of a vertical seal and a horizontal seal, and folding along the crease line. Filling because the flap and fin including the seal zone are joined to the container top wall, container side wall and container bottom to obtain a final rectangular container, and the liquid food in the container is solidified and solidified to obtain a product. Flap and fins are peeled off from the vessel wall at the time of food take-off, and the flap and / or fin can be easily formed by cutting the vicinity of the flap and / or fin with scissors, etc., at one end of the container. Can be.

The paper packaging container according to the present invention has an opening for taking out a filled food formed by cutting one end of the container, and an easily breakable portion at the other end opposite to the opening. When the easily broken portion is broken at the time of taking out the filled food, air enters from the broken portion, and this air also enters between the inner surface of the container and the contents. Tofu and jelly are not fluid, but the contents / filled food can be easily removed after opening because of the air between the inner surface of the container and the contents.
