DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette bag used in a soft ice cream manufacturing device (discharge device). The present invention also relates to a package in which the cassette bag is filled with a soft ice cream mix.

[0002]

2. Description of the Related Art <Ice creams> Ice creams are generally classified into four types: ice cream, ice milk, lacto ice, and ice confections (however, ice confections may not be included in ice creams). In the production of ice creams, after preparing an ice cream mix in which various ingredients such as fat, non-fat milk solids, sugar, stabilizer, emulsifier, and moisture are mixed and dissolved, filtration, homogenization, sterilization,
Aging is performed, followed by freezing in a freezer. In the freezer, the sterilized mix rapidly cools and freezes, during which time air is blown, and vigorous stirring forms fine and uniform air bubbles and ice crystals in the mix. As a result, the volume of the mix increases and the viscosity increases, and the mixture becomes a semi-fluid.
When the product is completely freeze-cured, it becomes product ice creams. For example, see pages 121-131 of "Commodity Knowledge Series, Actual Knowledge of Milk and Dairy Products, 4th Edition, Published by Toyo Keizai Shimpo, June 10, 1993".

<Soft Ice Cream> Among the above-mentioned processes, the one in the semi-liquid state is soft ice cream, and a sterilized mix is supplied to a freezer of a soft ice cream manufacturing apparatus at a storefront, and the soft Normally, one piece is discharged to an edible cone by lever operation and provided to the customer.

<Cassette Container for Soft Ice Cream> Recently, a cassette type container in which one soft ice cream mix is previously filled in a three-dimensional container comprising a lower cup and an upper cup manufactured by vacuum forming or deep drawing. Packaging has been proposed. The lower cup has a discharge port,
The outlet is closed with a label. The label covering the discharge port is peeled off and removed from the cassette-type package, supplied to the store equipment, and pressure is applied so that the container is crushed, so that the contents are discharged from the discharge port. It can be picked up in a cone and provided to customers.

[0005]

The above-mentioned cassette-type package using a three-dimensional container made of upper and lower cups,
Since one piece of soft ice cream can be made by simply applying pressure from above, there is an advantage that it is sufficient to stock only the required number of pieces, the discharge amount is constant, and the operation is simple.

[0006] However, this package requires a special device to join the upper and lower cups in the step of placing the upper cup after filling the contents, and a pressure is applied to the upper cup side of the three-dimensional container composed of the upper and lower cups. Is pressed toward the lower cup to discharge the contents from the discharge port provided in the lower cup, so that the upper cup is inverted from the upward convex shape to the downward convex shape. As a result, the deformation is remarkable, and in the course of the deformation, a problem may occur that the contents leak from the joint between the upper cup and the lower cup.
Furthermore, the three-dimensional container consisting of the upper and lower cups complicates the process of setting the label to close the discharge port, and the three-dimensional container before filling the contents is bulky. The bulk of the waste cup becomes large.

Under such a background, the present invention is easy to handle in storage and distribution processes, simplifies and downsizes various devices, does not cause any trouble at the time of discharging operation of contents, and has no waste. To provide a cassette bag for soft ice cream in the form of a flat bag made of film, and more specifically, to provide a soft ice cream mix filled in the cassette bag. It is intended to provide the body.

Here, examples of the base film include a biaxially stretched or unstretched nylon film, a biaxially stretched or unstretched polypropylene film, and a biaxially stretched polyester film. The base film may be a film coated with a gas barrier resin such as polyvinylidene chloride, ethylene-vinyl alcohol copolymer, or a laminate of these gas barrier resin layers. Therefore, it is often unnecessary to provide a gas barrier resin layer. The thickness of the substrate film is not particularly limited, but is often about 8 to 30 μm.

As the sealant layer, ethylene homopolymers and copolymers (polyethylene, ethylene-vinyl acetate copolymer, ethylene-acrylate copolymer, ionomer, ethylene-propylene copolymer, etc.), propylene homopolymer and Examples include layers of various resins having heat sealing properties, such as polyolefins such as copolymers, polyesters, and acrylic copolymers. Among these, low density polyethylene (L
DPE), linear low density polyethylene (LLDPE),
Propylene-based polymers (CPP) are particularly preferred. Although the thickness of the sealant layer is not particularly limited, it is 20 to 10
It is often about 0 μm.

The lamination of the sealant layer to the base film can be achieved by a method such as dry lamination, extrusion coating, coextrusion, or coating.

The first film (2A) and the second film (2B) may be the same or different. If a different one is used, the opening (3) described later
If the rigidity of the first film (2A) on the side where the and the plastics plate (4) are provided is smaller than the rigidity of the second film (2B), the discharge operation of the contents becomes smoother. it can.
