Description

Puffed snack box

technical field

The utility model relates to a fast food box, in particular to an environment-friendly fast food box which is easy to degrade and is mainly made of grain starch as a raw material, in particular to an expanded fast food box.

Background technique

As we all know, the field of fast food boxes in my country has been basically occupied by plastic (foam) lunch boxes for a long time. Plastic lunch boxes are difficult to degrade, have a long cycle, and are prone to carcinogens after heating or heating. It is a serious white pollution product and has a huge impact on the environment. The country has repeatedly reiterated that it should be eliminated. For this reason, since the late 1990s, some enterprises have tried paper lunch boxes and pulp boxes instead of plastic lunch boxes, but encountered new contradictions: the use of paper lunch boxes is not strong enough, and the raw material (pulp) of pulp boxes has brought new problems. Pollution, it needs to consume a lot of forest resources, and the cost is relatively high, all of which limit its popularization and application. In recent years, some people have proposed to use grain puffing technology to make lunch boxes. Although this solves the problem of raw materials, it also increases the outlet for some low-value-added crops. , easily soluble problem, has not been marketed.

Contents of the invention

The purpose of the utility model is to design a kind of puffed fast food box which is waterproof, good in strength and suitable for marketization, aiming at the problem that the current puffed fast food box is difficult to be popularized and applied due to fear of water and insufficient strength.

The technical scheme of the utility model is:

A puffed fast food box, which is composed of a box cover 1 and a box seat 2, the box cover 1 is either engaged on the upper opening of the box seat 2 or connected to one side of the upper opening of the box seat 2, and is characterized in that the box The seat 2 is composed of an expanded layer 3 , an inner wall waterproof layer 4 and an outer protective layer 5 , and the expanded layer 3 is sandwiched between the inner wall waterproof layer 4 and the outer protective layer 5 .

Described inner wall waterproof layer 4 is waterproof paper (preferably adopts edible waterproof paper) or waterproof adhesive layer.

Described outer protection layer 5 is starch glue layer, waterproof glue layer, PVC film or waterproof paper (preferably adopts edible waterproof paper).

The expanded layer 3 is grain starch expanded product.

Described lid 1 is also made up of puffed layer, inner wall protective layer and outer protective layer, and expanded layer is positioned between inner wall protective layer and outer protective layer, and inner wall protective layer is waterproof paper (preferably adopts edible waterproof paper) or waterproof glue layer, and the outer protective layer is starch glue layer, waterproof glue layer, PVC film or waterproof paper.

The beneficial effects of the utility model:

The utility model solves the long-term unsolved problems of fear of water and insufficient strength of the puffed fast food box, and lays a foundation for the marketization of this type of fast food box.

The utility model has the advantages of simple structure and convenient manufacture, and can be formed at one time through a mold while manufacturing the puffed layer.

The fast food box of the utility model also has the characteristics of light weight, anti-seepage, water temperature resistance, and easy transportation, and can fundamentally solve the white pollution caused by the use of the lunch box. Responding to the State Economic and Trade Commission's No. 6 order on April 22, 1999, it also expanded the use of crop waste.

The utility model also has a series of advantages such as low price and easy degradation.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Embodiment one

As shown in Figures 1 and 3.

A puffed fast food box, which is composed of a box cover 1 and a box base 2, the box cover 1 is engaged on the upper opening of the box base 2, as shown in Figure 1, and several partitions can be set inside the box base 2 according to the needs during specific implementation. In order to facilitate the packaging of dishes and staple foods by category. The box seat 2 is made up of an expanded layer 3, an inner wall waterproof layer 4 and an outer protective layer 5, and the expanded layer 3 is sandwiched between the inner wall waterproof layer 4 and the outer protective layer 5, as shown in FIG. 3 . Wherein the inner wall waterproof layer 4 or adopts waterproof paper (preferably adopts edible waterproof paper) to cover or spray waterproof glue (edible glue) to form a waterproof glue layer. Outer protective layer 5 can be starch adhesive layer, waterproof adhesive layer, PVC film or waterproof paper (preferably adopt edible waterproof paper) manufacture. The puffed layer 3 in the middle can adopt grain starch puffed thing.

During specific manufacturing, the lid can be made of other degradable materials, or the material of the same structure as the box base 2, that is to say, the lid 1 can also be made of the same expanded layer, inner wall protection layer and outer side as the box base 2. The protective layer is composed of a protective layer, the expansion layer is located between the inner wall protective layer and the outer protective layer, the inner wall protective layer is waterproof paper (preferably edible waterproof paper) or waterproof adhesive layer, and the outer protective layer is starch adhesive layer, waterproof adhesive layer, PVC film or waterproof paper.

During the specific manufacturing, a certain amount of grain starch (such as corn, generally a few corns can be used for a fast food box) can be sent into the lunch box mold together with the puffing agent and the toughening material. A layer of waterproof paper (edible) is pressurized on the inner wall of the lunch box (box seat and box cover) (it can also be replaced by spraying a layer of waterproof glue) to form the inner protective layer of the lunch box, which is automatically sprayed on the lunch box by the nozzle installed on the forming machine. Spray starch glue on the outer layer (you can also pressurize waterproof paper, spray waterproof glue, or even cover with PVC film) to form an outer protective layer. Finally, it is dried and sterilized on a conveyor dryer.

Embodiment two.

As shown in Figure 2 and 3.

The difference between this embodiment and Embodiment 1 is that the connection mode between the box cover 1 and the box seat 2 is different. Separation is a common one-piece structure so that the dishes and staple foods are divided into categories, while the lid and the box seat of Embodiment 1 are a split-type snap-in structure.

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art.
