Description

DETAILED DESCRIPTION OF THE INVENTION The present invention stores food in a synthetic resin thin film cylinder whose lower end is sealed by heat welding, and extends the upper thin film cylinder of the stored food into a flat cylindrical shape. The lower part of the flat cylindrical part is formed into an inverted triangular shape by squeezing the middle part between the part and the food storage part, and a string or tape is wound slightly below the lower end of the inverted triangular part to form the constricted part. The present invention relates to a food packaging method comprising the steps of forming a rectangular portion, and then laterally cutting the inverted triangular portion in the middle and welding and sealing the portion.

To explain the embodiment of the present invention shown in the drawings, the machine frame 1
A synthetic resin thin film cylinder 4 whose lower end is sealed by heat welding 3 is inserted in a bellows-like manner into the funnel 2 which hangs down (see Fig. 2).

The funnel 2 may be covered with a synthetic resin winding sheet, and the fixed heating piece 5 is in contact with the intermittent movable heating piece 6, so that the sheet is formed into a cylinder around the outer periphery of the funnel 2 (see FIG. 3). This thin film cylinder 4 is laterally extended into a flat cylinder shape 10 by extension springs 7 and T provided at the lower end opening of the funnel 2. When the food (boiled noodles) 8 is put into the funnel 2 and accommodated in the lower end of the thin film cylinder 4, the cylinder 4 descends due to the weight of the food 8 and is supported on the base plate 9 (first figure). In this state, the middle part of the flat cylindrical overhanging part 10 and the food storage part 11 is squeezed at two places on the upper and lower sides by the drawing rods 12 and 13 which are perpendicular to each other. An inverted triangular portion 15 having a lower end portion 14 is formed below the flat cylindrical portion 10 . Then, a string is wound around and tied to a slightly lower part of the lower end portion 14, or an adhesive tape 16 is wound around and secured to the constricted portion 17.
form. In this state, when the middle portion of the inverted triangular portion 15 is cut by fusing with a heating wire along the transverse fusing line a, the cut portion is sealed by heat welding 18 .
Heating bands for sealing are placed above and below the heating wire, and at the same time as the heating wire cuts the heating wire, heat welding sealing parts 3 are placed at the top and bottom of the fusing part;
19 (solid line in FIG. 2, imaginary line in FIG. 4, and phantom line in FIG. 7) may be formed. When the drawing rods 12 and 13 are opened after the fusing, the lower part of the inverted triangular portion 15 expands from the position shown by the solid line in FIG.
5', the fusing edge 18' is curved upward, and the plurality of vertical wrinkles 20 causes the upper part of the constricted portion 17 to stand upright in a chain shape (see FIG. 4). In the conventional food wrapping method, the upper part of the stored food is squeezed, the squeezed part is secured with string or tape, and the packaging process is finished with the upper end left open. However, food packaging is not suitable for long-term storage because it is easy for germs, dust, insects, or sewage to enter. Since the present invention is based on the above-mentioned method, the upper edge is welded and sealed 18, and there is no risk of entry of putrefactive bacteria, various bacteria, dust, insects, or sewage, and the present invention is not only suitable for long-term storage, but also is suitable for long-term storage.
The upper part of the fin-like part 21 is formed into a flat fin-like part 21, and the sealed 18-fused cut edge 18' is curved upward, and the upper ends of the plurality of longitudinal wrinkles 20 are welded and fixed to the sealed part 18, thereby forming the fin-like part 21. It can be held upright and the fin-shaped portion 21 can be easily grasped by hand, thereby significantly improving the packaging appearance and packaging effect.

Claims (1)

[Scope of Claims] 1. A food product 8 is housed in a synthetic resin thin film cylinder 4 whose lower end is sealed by heat welding 3, and the upper thin film cylinder 4 of the stored food product 8 is made to protrude into a flat cylinder shape. The lower part of the flat cylindrical part 10 is formed into an inverted triangular shape 15 by narrowing the middle part between the protruding part 10 and the food storage part 11, and the lower end 1 of the inverted triangular part 15 is formed.
A string or tape 16 is wound around the slightly lower part of 4 to create a constriction part 17
A method for fast food packaging comprising the steps of: forming a rectangular triangular portion 15; 2. The food kinchyaki packaging method according to claim 1, wherein the food 8 is boiled noodles.
