Description

Disposable lunch box

technical field

The utility model relates to the technical field of daily necessities, in particular to a paper disposable lunch box.

Background technique

In life, fast food lunch boxes generally refer to disposable lunch boxes. In the market, many lunch boxes are reused or deliberately opened on the way of delivery without the user's discovery. Such a lunch box structure loses the meaning of disposable use and safety, and there is a risk Problems such as food contamination and poisoning pose potential safety hazards. For example, the utility model with the application number: 201720127809.X discloses a lunch box, which includes a box body and a box cover. The box body and the box cover are both made of food-grade plastics. Buckle tongue, the edge of the box cover is provided with a buckle groove suitable for the buckle tongue, the buckle groove and the buckle tongue are an irreversible mother-in-law upside-down structure, and the box cover is provided with a concave pull groove. Between the button slot and the box cover, there is a circle of V-shaped gaps for easy opening. This is a patent for a one-time-use lunch box applied by our company. Its material is plastic, and it is very difficult to make a degradable paper-based fast food box that can only be used once. Another example is the application number: 201610848608.9, a paper cup lid and its processing technology. It is characterized in that: the paper cup cover has an integrated structure, and its processing steps include material taking, molding, bottom folding, knurling, and its structure includes a round top and a ring side around the bottom; the middle of the ring side is The segment is formed with a step, and the bottom of the side of the ring is provided with a flange that is turned inwards and clings to the inner wall of the side of the ring. This is the manufacturing process of the paper cup lid, which lacks a manufacturing process of the whole lunch box.

Contents of the invention

The utility model focuses on solving the difficulty in fastening the box body and the cover of the disposable paper lunch box in the prior art, and provides a paper disposable fast food box.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a disposable lunch box, including a paper box body and a cover body, characterized in that the upper part of the box body is a cylindrical structure, and the circular The lower end of the barrel structure is inner curling or hemming or straight edge, the lower part of the box body is barrel or cone barrel structure, and the port of the barrel or cone barrel structure is outer curling or inner curling or Flange or straight edge, the lower end of the cylindrical structure is pressed and connected with the port of the barrel body or the cone barrel structure, forming steps inside the box body, and the upper part of the cylindrical structure is provided with curling or folding The edge or protrusion, the curled edge or folded edge or protrusion and the step form a groove, the groove is embedded in the cover body, the cover body is composed of double-layer cardboard or three-layer cardboard, and the outer edge of the cover is provided with an outer Curling edge or side edge, the upper cardboard of the cover body is provided with an opening device.

The biggest feature of this kind of paper disposable fast food box is that the cover is plugged inside the upper part of the box body, and the steps on the inner side of the upper cylindrical structure of the box body and the grooves formed by curling or folding or protrusions are in line with the circle of the cover body. The crimping or folding on the outside of the cylinder cooperates with each other, and its purpose is to prevent the lid from being easily opened. Of course, since the interference of this snap-fit connection will not be too large, the cover can definitely be opened with a suction cup or other tools, but it is difficult to open it by hand without damaging the cover or box, or leave room for prying. There are no traces of opening, so it has anti-theft function. The lid is fastened inside the box, and there is no point of force. To open the lid, you can only use the opening device on the lid, and the lid can only be opened by destroying the lid. This ensures that the food in the lunch box is opened for the first time , because it is a paper lunch box, it can be degraded. The box body adopts the structure of crimping the upper and lower parts. The main purpose is to provide a step at the connection point to facilitate the positioning of the cover body; Squeeze out.

Preferably, the lower end of the cylindrical structure is press-fitted and connected with the outer crimp of the port of the barrel or the tapered barrel structure by an inner crimp. The lower end of the cylindrical structure has inner crimping on the bottom, and the outer crimping of the port of the barrel or cone barrel structure is on the top, and is connected by ultrasonic pressure bonding.

Preferably, the lower end of the cylindrical structure is crimped and connected with the port of the barrel or the tapered barrel structure by straight edges. The lower end of the cylindrical structure is curled inside, and the straight edge of the barrel or cone barrel structure is outside, and is connected by ultrasonic pressure bonding.

Preferably, the lower end of the cylindrical structure has a straight edge and is crimped and connected to the inner port of the barrel or the tapered barrel structure. The lower end of the cylindrical structure has a straight edge on the outside, and the inner crimping of the port of the barrel or cone barrel structure is on the inside, and is connected by ultrasonic pressure bonding.

Preferably, the lower end of the cylindrical structure is buckled and press-fitted with the flange of the barrel or the port of the cone barrel structure. The lower end of the cylindrical structure is an inner flanging, and the outer flanging of the port of the barrel body or the cone barrel structure is fastened to each other and connected by ultrasonic pressure bonding.

Due to the adoption of the above-mentioned technical scheme, the lunch box provided by the utility model has such beneficial effects: through the innovation of the structure and manufacturing process of the box body and the cover body, a kind of lunch box with simple structure, low cost, and convenient operation and use is provided. Disposable paper lunch boxes have the ability to prevent secondary use and ensure food safety. At the same time, the product can be degraded and meets modern environmental protection requirements.
