Description

Anti-hot paper plastic container

The invention relates to an anti-scalding paper-plastic container, in particular to a body with good heat insulation and anti-scalding effect, high top edge strongness, no difficulty in softening of the body and the top edge, and a circulation space at the bottom, which helps to prevent heat from falling. Paper plastic container.

Press, hot foods are often exposed in daily life, especially hot foods with hot soup. Because they are hot, they must be packed in containers. When you are at home, you can still use the pots and pans in your home to hold them, but you have to rely on (using) the containers provided by the outside world. Nowadays, in an era of extremely developed industry and commerce, many people, especially office workers and foreign eateries, spend their daily lives outside and outside the country. Therefore, relying on (using) the outside world to provide containers is particularly deep, and may go to brand chain supermarkets or fast food in the morning. Shop to buy a cup of coffee to start a day of work, buy a Oden from the supermarket at noon (including soup) is a Chinese meal, and at night to go to the supermarket to buy a cup noodles (or bowl noodles) for dinner, this is a day. Among them, the coffee cups containing coffee, the soup bowls filled with soup Oden, and the cups filled with cup noodles (or bowl noodles) are containers provided by the outside world. It can be seen that containers that can hold hot food and modern people are used. Life can't be separated.

For convenience and hygiene, when buying a coffee from a brand chain supermarket or fast food restaurant, the store must use "outer paper cups" to hold coffee to customers; when buying soup with Guandong, the store is to give customers a "takeaway paper bowl". "Let customers choose soup Guandong to put in and add soup. As for the cup noodles (or bowl noodles), the noodles and additives are already packaged in a "takeaway paper bowl" for sale. Therefore, "outer paper cups" and "outer paper bowls" are all "convenient food containers", or "outer paper cups" and "outer paper bowls" are often referred to as "disposable paper containers", "once The name of the "hands-on container" or "discarded paper container"---etc.

At present, a paper container 1 which is conventionally known in the market, as shown in Figs. 1 and 2, is formed by using a paper sheet as a material, by bending, laminating, rolling, etc., to manufacture a body 11 and a combination thereof. The bottom film 12, the volume range defined by the body 11 and the film 12 is a storage space 13, please refer to the top of the paper sheet of the body 11 and the paper periphery of the film 12 as shown in FIGS. The bonding is achieved by means of lamination and rolling to cover a bottom space 14. The top of the sheet of the body 11 is formed by outward bending to produce a top edge 15, and thus at the top edge 15 There must be a gap 151 inside the interior.

The conventional paper container 1 may have the following defects in use:  1. The body 11 of the conventional paper container 1 is a paper sheet. Therefore, when the hot food soup is taken at the end, the finger between the end finger and the hot food soup is separated only by the body 11 of the paper sheet, and the body 11 is The thickness of the paper sheet is obviously insufficient in the heat insulation and anti-scaling effect, and sometimes the body 11 may be perceived to have a phenomenon of softening by heat, in other words, the heat insulation of the body 11 of the conventional paper container 1 is anti-scalding. not effectively.  2. The top edge 15 of the body 11 of the conventional paper container 1 is formed by bending only the paper sheet. In particular, the gap 151 is further present inside the top edge 15 so that the strength is insufficient, in other words, the conventional paper. The top edge 15 of the body 11 of the container 1 has a poor heat-resistance effect, and often there is a case where the hot-filled soup is placed, and the top edge portion 15 is softened, causing troubles in the use of the hot soup.  3. The bottom of the body 11 of the conventional paper container 1 is a wrap-around shape. Therefore, when the conventional paper container 1 is placed on a flat surface (for example, a table top), the hot air in the bottom space 14 cannot be externally penetrated. It does not help the cooling of hot food, that is, its cooling effect is not good.  

As can be seen from the above description, the conventional paper container 1 is made of a sheet-like paper sheet, so that the body 11 has a poor anti-scalding effect, and the top edge 15 has insufficient strength, poor heat resistance, and is easily softened by heat. The bottom space 14 does not contribute to the absence of use in cooling or the like.

The outer side of the side of the support leg forms a flow space for outward passage, and the inner edges of the support legs are connected to each other to form the negative film.

In the anti-scalding paper-plastic container described above, the anti-scalding flange is more prominent than the body of the body.

In the anti-scalding paper-plastic container described above, the anti-scalding flange is vertically aligned in an upright and upright shape.

In the above anti-scalding paper-plastic container, the backsheet is formed into an upwardly slightly concave configuration.

According to the above configuration, the present invention has the following excellent effects in use:  1. The anti-scalding paper-plastic container of the invention adopts the suction-slurry forming, and the thickness of the body can be formed relatively thick (compared with the above-mentioned conventional paper container), so the heat-insulating anti-scaling effect of the main body is remarkably improved.  2. The anti-scalding paper-plastic container of the invention adopts the suction-slurry forming, and at least two symmetrical faces of the external body sheet are formed with a plurality of anti-scalding flanges which are more prominent than the body of the body, and the hot food is taken at the end. When the soup is hot, the anti-scalding flange can keep the fingers of the end holder away from the heat source, so that the anti-scalding effect can be better.  3. The anti-scalding paper-plastic container of the invention adopts the suction-slurry forming, the top of the body and the anti-scalding flange are formed with the solid top edge, forming a strong supporting structure on the top of the anti-scalding paper-plastic container, and the overall heat resistance is improved. Sex.  4. The anti-scalding paper-plastic container of the present invention is formed by suction molding, and the bottom surface of the body is integrally formed with at least three support legs of a wide and thick body which are equally divided, and the negative film is connected and formed between the inner edges of each support leg.
