Description

  The present invention relates to a post-meal container and an uneaten separation method for instant food packaging containers used for pouring hot water into a container body and eating instant food (instant noodles, etc.) in an edible state. Immediate food packaging containers that make it easy to separate combustible and non-combustible waste by separating the food contents left in the container body after meals into solid and liquid by a simple method. The present invention relates to an after-meal container and a method for separating leftovers.

  Instant foods have various advantages such as excellent storage, portability, and convenience. Cup noodles, one of the representative instant foods, are edible by pouring hot water into the container body. However, when leftovers after meals (solid materials such as noodles and utensils, and liquid materials such as soup) are produced, the separation process may be problematic. When eating at home, it can be poured into a draining basket or draining net in a kitchen sink to separate and separate these solids and liquids, but this is not possible especially when eating outdoors. For this reason, there arises a situation where the sorting process is troubled.

  Among the instant food packaging containers, there is known a lid structure that allows separation of solid and liquid food left in the container body after eating (Patent Document 1).

  This has a structure in which the lid is composed of a double structure of an outer lid and an inner lid, and the inner lid is divided into two parts, a part with a small hole and a part with no small hole. When it is opened widely, the inner lid portion without the small hole sticks to the outer lid and peels off at the same time, and only the inner lid portion with the small hole sticks to the container body side. After eating, the container is tilted, and leftover food is collected on the side of the inner lid that remains attached to the container body, and the liquid is filtered to separate it from the solid.

  However, although the above structure can separate the solid matter, in order to separate the combustible waste and the non-combustible waste, it is necessary to separate the solid matter separated on the container body side from the container body (the container body is Usually made of synthetic resin such as polystyrene and treated as non-combustible waste.)

  Moreover, although the structure which provides the hole for hot water cutting in the peripheral part of a lid | cover is known (patent document 2), even if this hole can be utilized for isolation | separation of the food content which remains in a container main body, after isolation | separation This is the same as the conventional structure described above in that it is necessary to further separate the solid matter remaining on the container body side from the container body.

JP 2002-145352 A

  The present invention is capable of separating the food content remaining in the container body that is leftover after eating into a solid and liquid by a simple method, and the subsequent container body and leftover solid It is an object of the present invention to provide an after-meal container and an uneaten separation method for instant food packaging containers that can facilitate the separation process.

In order to solve the above-described problems, a plastic container main body that stores instant foods that are edible by pouring hot water and a paper lid that covers the top opening of the container main body are provided. A method for separating after-meal containers and leftovers of instant food packaging containers, comprising a plurality of small hole groups on the back of the lid for separating leftovers after meals into solid and liquid foods A semicircular paper filter portion occupying half of the area of the lid is provided, and the periphery of the circular arc portion of the filter portion and the periphery of the lid are attached, and after eating, the food becomes edible. Open the lid and the filter part separated from the container for eating instant food by folding the lid and the filter part so that a dent is formed between the lid and the filter part. Pour the food contents remaining in the container body from above, Separated, and the thereafter separated solid product as they combustible waste wrapped in the lid and the filter unit, also as to fractionating the plastic container body as incombustible refuse.
The uneaten liquid material separated from the solid material is stored in a dedicated container or the like and processed separately from the solid material.

  The container body is made of a single material or a combination of composite materials such as polystyrene (PS) resin, polyethylene (PE) resin, polypropylene (PP) resin, and polyvinyl chloride resin. A plastic container body made of such a material is classified as non-burnable waste.

  The material of the lid is mainly paper, and the types of paper include single-sided art paper and double-sided art paper, as well as coated paper and high-quality paper. Aluminum foil (gas barrier layer), polyethylene film (sealant layer), or the like may be laminated on the front and back surfaces of the paper as auxiliary materials. A paper lid made of such a material is separated as combustible waste.

  The diameter of each hole of the small hole group of the filter part is preferably 1.0 mm to 7.0 mm. Separation takes time when the diameter is less than 1.0 mm. If it exceeds 7.0 mm, solid materials such as noodles, utensils, and fragrance may leak from the small holes in the filter section. These small hole groups may be composed of a large number of small holes having the same diameter, but it is desirable to mix a large number of small holes having different diameters (large, medium, and small). According to the latter, further improvement in separation efficiency can be expected.

  The number of small holes in the filter part is preferably 25 or more and 150 or less. If it is less than 25, it takes time to separate. If it exceeds 150, the cost will increase and the efficiency of separation will not change much. In addition, these small hole groups may be arranged regularly, but may be arranged irregularly.

  According to the instant food packaging container of the present invention and the after-meal separation processing method, the left-eaten after-meal meal is made using the lid body separated from the container body and the filter unit attached to the lid body. The food content remaining in the container body can be separated into solid and liquid, and in the subsequent separation process of the container body and uneaten solid matter, Since the solid matter remaining in the dent can be securely wrapped by the lid and the filter part, this uneaten solid matter together with the paper lid and filter part is separated and disposed of as combustible waste. Can be separated as incombustible waste, and the process from separation of uneaten solid matter and liquid matter to separation treatment of combustible waste and incombustible waste is extremely simple, and can be performed easily and smoothly.

  Hereinafter, embodiments of the post-meal container and the uneaten separation processing method of the instant food packaging container of the present invention will be described with reference to FIGS.

FIG. 1 shows the appearance of an instant food packaging container 1 used in the method for separating after-meal and leftover food of the instant food packaging container of the present invention.
The instant food packaging container 1 includes a plastic container body 2 made of plastic (foamed polystyrene resin) in which instant noodles (not shown) are accommodated, and a paper lid body 3 that covers the upper surface opening of the container body 2. On the back surface of the lid 3 is a semicircular paper filter unit 10 composed of a large number of small holes 11 for separating leftovers after meals into solids and liquids. The lid 3 is adhered along the peripheral edge of the lid, and the lid 3 is bonded to the upper peripheral edge 2a of the container body 2, and a pull tab 4 for opening is provided on a part of the outer peripheral edge of the lid 3. Yes.

  By attaching the filter unit 10 to the back surface of the lid 3, the filter unit 10 is hidden from the front side of the instant food packaging container 1, so that the appearance of the package state is not impaired, and the filter unit 10 can be easily attached to the lid 3. Can be added.

  Next, the post-meal container and the uneaten separation processing method of the instant food packaging container 1 will be described.

  As shown in FIG. 2, after separating the lid 3 formed by attaching the filter unit 10 on the back surface from the container body 2, a recess is formed between the lid 3 and the filter unit 10 as shown in FIG. 3. The container body 2 that is a leftover after eating after the upper body of the lid body 3 is gripped in a state where the lid body 3 and the filter section 10 are folded and the gap between the lid body 3 and the filter section 10 is opened. Pour the food contents that remain inside. Then, a liquid thing is discharged | emitted from each small hole 11 of the filter part 10 among food contents, and solid things, such as a noodle, a tool, and a fragrance, remain in the dent between the cover body 3 and the filter part 10. FIG.

  After that, the solid material is wrapped by the lid 3 and the filter unit 10, and these are combined together as combustible waste, and the plastic container body 1 may be separated as non-combustible waste. Moreover, what is necessary is just to accommodate the liquid thing discharged | emitted from each small hole 11 of the filter part 10 in a special container.

  Instead of the paper filter unit 10, a draining net that can be treated as combustible waste (a large number of small hole groups are formed in a mesh shape) can be attached to the back surface of the lid 3. It is. Further, the paper filter unit 10 and the draining net are stored in the container body 2 together with other soup storage bags when the instant food packaging container 1 is in a package state, and taken out when used. You may set it as the structure attached to the back surface or surface of the cover body 3. FIG. As an attachment means, an adhesive portion may be provided on either the lid 3 or the paper filter portion 10.
