Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a milk paper cup consisting of a combination container packaging.

[0002]

[Prior art]

 Conventionally, milk bottles and other dairy products have been packaged in glass bottles, polyethylene containers and polyethylene paper containers and packaging, and commercially available Goebeltop and brick pack types are polyethylene processed paper containers and packaging. And recently, it has been approved that a combination container and packaging of polyethylene and polyethylene-processed paper can be used as a packaging for dairy products.

[0003]

[Problems to be solved by the device]

 Among the conventional milk containers as described above, the commonly used brick pack type and gobel top type have the following problems. In other words, in the brick pack type, it was necessary to form the straw insertion port. The Gobel top type is difficult to open and cannot be opened with one hand. Therefore, the object of the present invention is to obtain a milk paper cup that is easy to open and easy to hold with one hand, without the need to form a straw insertion port.

[0004]

[Means for Solving the Problems]

 In order to achieve the above objectives, this plan provides the following milk paper cups. That is, the cup body with the flange formed on the top consists of a polyethylene paper layer formed on the inner and outer surfaces of the base paper, and at least the polyethylene layer on the inner surface side of the cup is formed of an additive-free polyethylene layer and is bonded to the flange. The lid material is a milk paper cup in which a base paper and aluminum foil are laminated via a polyethylene layer and at least an additive-free polyethylene layer is formed on the inner surface.

[0005]

[Function] Since the lid material is made by laminating the base paper and the aluminum foil via the polyethylene layer, the lid can be easily opened with a straw, and the container is cup-shaped and can be held with one hand.

[0006]

【Example】

 Embodiments shown in the drawings will be described below. Reference numeral 1 denotes a paper cup body composed of a body portion and a bottom portion, which has a cup-like conical shape, and a curled flange 2 is formed on the upper portion. The container shape may be, for example, a pyramidal shape, a taper-free cylindrical shape, or a rectangular tube shape. In addition to the curls, the flange 2 may be formed in a flat plate shape, a curled shape that is crushed into a flat shape, or the like. The material of the cup body 1 is one in which polyethylene layers 5 and 4 are formed on the inner and outer surfaces of the base paper 3, and the polyethylene layer on the inner surface is an additive-free polyethylene layer. This additive-free polyethylene is used to prevent additives such as antioxidants from being dissolved in milk when the container is used as a milk container. As the base paper, for example, acid-resistant paper is used, and the basis weight of the body is 300 g / m2 and the basis weight of the bottom is 240 g / m2. The thickness of the additive-free polyethylene layer on the inner surface is 40 μ at the body and 40 μ at the bottom, and the thickness of the polyethylene layer on the outer surface is 20 μ at the body and 15 μ at the bottom. Reference numeral 6 denotes a lid material that is adhered to the flange 2, and heat sealing, high frequency sealing, ultrasonic sealing or the like can be considered as the method of bonding. As the material of the lid member 6, a material in which an aluminum foil 9 is laminated on a base paper 7 with a polyethylene layer 8 interposed and a polyethylene layer 10 is arranged on the inner surface is used, and the polyethylene layer 10 is made of additive-free polyethylene like the cup body. To use. As the base paper 7, a material having good printability and concealing aluminum foil is used. For example, a base paper having a basis weight of 52.3 g / m @ 2, a polyethylene layer 8 having a thickness of 15 .mu.m and an aluminum foil 9 having a thickness of 20 .mu.m are used. The polyethylene layer 10 has a thickness of 30 .mu.m, and the relatively thick aluminum foil having a thickness of 20 .mu.m is used to form the curl prevention layer. A printing 11 is applied to the surface of the base paper 7, an OP layer (overprinting) 12 is formed on the surface of the base paper 7, and the surface of the base paper 7 is embossed to form a rough surface, which helps prevent blocking during stacking of the lid material. It has become.

The above paper cup is used as a hermetically sealed container for dairy products such as milk, skim milk, processed milk, and cream, which is a newly approved combination container and packaging of polyethylene and polyethylene processed paper. Since it is compatible and additive-free polyethylene is used on the inner surface of the container, additives such as antioxidants do not elute into dairy products. In any case, since the lid of this proposal uses a combination of base paper and aluminum foil, it is easy to open with a straw and the container is cup-shaped, so it is easy to hold and the material of the base paper is also used. Since the inner and outer surfaces are formed of polyethylene layers, a relatively strong cup body at the waist can be obtained.

[0008]

[Effect of device]

 The container of this proposal is cup-shaped and uses a base paper with a polyethylene layer formed on the inner and outer surfaces, so it is relatively strong and easy to hold with one hand, and the cover material uses base paper and aluminum foil. Since it is easy to open with a straw, it is not necessary to form a straw insertion port. Moreover, it is easier to manufacture than the brick pack type and gable top type, and since the main body is paper, a paper cup with a good appearance can be obtained. However, since the additive-free polyethylene is used for the surface of the inner surface of the cup that comes into contact with the dairy product, the additive does not elute into the milk and a suitable milk paper cup can be obtained.
