Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for semi-solid ice confectionery such as ice cream and shaved ice, and a method for manufacturing the same, and more particularly to a container for tube-shaped (toothpaste tube-shaped) ice confectionery and a method for manufacturing the same.

Containers made from quefers, such as wafers, are well known as containers for iced confectionery, but recently, plastic cup-shaped containers have been used instead of wafers. However, cup-shaped containers always require a spoon, which is inconvenient for both manufacturers and consumers. In particular, the unsanitary nature of this situation has been pointed out in the media, as both hands are needed to hold the spoon and the other hand to hold the spoon, and children's hands can get dirty from their hands into the container through the spoon. There have been times when this has become a problem.

Recently, extruded tube-shaped containers that can be eaten with one hand and without a spoon have been created and used. This eliminated the need for a spoon, eliminating the inconvenience caused by spoons, but since the container was tube-shaped, it naturally became elongated, and a thick glass sheet had to be used to strengthen the back. Increasing the wall thickness is also necessary to maintain the frozen state of the contents for as long as possible.In other words, the hand holding the container is shielded from the cold air, and the hand that is holding the container is constantly changing hands, wrapping around the container, etc. There is no need to wrap it with etc.

However, in practice, in order to fully achieve these effects, it is necessary to select a fairly thick plastic sheet to be used, which poses problems in terms of manufacturing and cost.

This invention was made from this point of view, and can be summarized as follows: A relatively thin plastic sheet is formed into a double-walled structure with a small gap without using a spacer, and the air in the gap is It provides a heat insulating effect, strengthens the wall with double walls, and eliminates the need for curling the edges of the opening (the process of creating a cohesive appearance with curls). A detailed description will be given below based on the drawings.

In FIG. 1, the reference numeral 1 indicates a spindle-shaped plastic container prototype integrally formed into a hollow shape by glow molding. The center □ band 2 forms a toe around the entire circumference and is hereinafter referred to as the hinge section. This prototype 1 is easily formed by a conventionally known method. The prototype 1 has an inner wall section 11 at the top and an outer wall section 1 at the bottom.
is formed and the entire inner wall is forcibly pushed into the outer wall (1 tatami mat) to the state shown in Fig. 2. Hinge part 2
is bent into a round shape to form the opening edge of the container 5. In the conventional method, the main body of the container 5 was formed and the opening edge was formed by cutting, which required a separate curling operation. This curling process is performed on the container 5' drawn with imaginary lines as shown in Figure 3.
The upright opening edge 2I is heat-treated to curl into a rounded edge 2°', and a large number of containers (120,000 to 130,000 pieces produced in 8 productions at the peak of demand for ice sweets) are individually curled. Performing this work is very time-consuming and naturally increases the cost.

However, according to the method of the present invention, the hinge portion 2 is naturally curled just by the previous pushing operation, and the conventional curling operation as a separate process is completely unnecessary.

The inner wall part 1□ becomes the inner wall part of the container 5 with a gap 4 formed from the outer wall part 1. Air exists within the void 4 and serves as a heat insulator. That is, the cold air inside the container 5 is blocked from going outside, and the temperature of the outside air is also blocked to protect the contents from the outside air temperature. The pipe is double-walled, so the container 5
The wall will be reinforced accordingly.

The opening of the container 5 is appropriately covered with a lid 6. The lid 6 can be of various types, such as a cap-shaped one or a sheet-shaped one (as shown), depending on the taste of the ice candy maker.

In this way, the container of this invention has a double structure with voids interposed without using any spacers, so it has a heat insulation effect due to the voids, a reinforcing effect due to the double wall, and a curling effect on the opening edge. It can be played all at once, and combined with the reduction in manufacturing costs, its practical value is extremely high.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; FIG. 1 is a vertical cross-sectional view of a container prototype, FIG. 2 is a vertical cross-sectional view of a completed container, and FIG. 3 is a conventional curled state of the opening edge of the container. This is an explanatory diagram showing for comparison.

The inner wall of the spindle-shaped container prototype formed by integral molding of plastic is replaced with the outer wall! 1. A method for producing an ice confectionery container with a bent part 2 formed as an opening edge by pushing the container into the container.
