Description

The present invention relates to a fractionation how processing method of leftovers and postprandial container of instant food packaging container that is used to eating in the instant food (instant noodles, etc.) in the edible state by pouring hot water into the container body, in particular food contents remaining in a vessel with leftovers postprandial, and separated into solids and liquids in a simple manner, together container and the combustible waste fractionation was easily the instant food packaging containers The present invention relates to a method for separating after-meal containers and 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 soups) occur, 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 part without the small hole sticks to the outer lid and peels off at the same time, and only the inner lid part with the small hole remains stuck 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 can separate the food contents remaining in the container body that is left over after eating into a solid and liquid by a simple method . an object of the present invention is to provide a separation processing method of leftovers and after a meal of the container of the packaging container for instant foods that can be used to facilitate the separation process with.

In order to solve the above-mentioned problem, in the separation processing method of the post-meal container and the uneaten of the instant food packaging container of the present invention, a plastic container body in which the instant food that is made edible by pouring hot water is stored in central region except lid made of paper and its periphery which covers the upper opening of a filter portion consisting postprandial leftovers from multiple small holes for separating solids and liquids, the lid And a sealing part attached to the surface side of the container, and after separating the lid from the container body, the sealing part is peeled off, and a conical shape is formed so that the center of the filter part of the lid is recessed. Next, the food content remaining in the container body is poured into the recess of the filter part from above to separate it into solid and liquid, and then the solid separated on the lid is wrapped in the lid. Both of them are combustible waste, and the plastic container body is nonflammable. So that the separation process as a body.

  According to the present invention, using the lid separated from the container body, the food content remaining in the container body, which is left over after eating, can be separated into a solid product and a liquid product. The lid can be prepared in the shape of a cone or pyramid, etc. so that the filter part is recessed, and if the food content in the container body is poured into it, it is extremely easy to spill out from the lid. In this way, after-meal leftovers can be separated into solid and liquid.

  Moreover, in the subsequent separation process, the solid matter remaining on the lid can be securely wrapped in the lid by closing the upper opening of the lid, and together with the paper lid, combustible waste Can be disposed of separately. That is, operations from separation of leftovers to separation processing are easy and smooth. On the other hand, the liquid material separated from the solid material is stored in a dedicated container or the like and can be 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 lid body, it is preferable to install a seal portion for covering the multiple small holes of the filter portion on the surface side of the lid. If Hegase seal portion, while it is possible to expose the filter portion consisting of several small holes on the upper surface of the lid, the package state before eating, the seal portion is concealed multiple small holes, packaging The appearance as a container is not impaired.

Furthermore, the cover body is composed of a lower layer portion having a filter portion in the central region and a surface layer portion laminated thereon, and a seal portion surrounded by a cutoff line is formed in the central region of the surface layer portion , It is desirable that the filter portion appears in the central region of the lid body by pulling up the seal portion and peeling it from the lid body.

  As a result, the seal part becomes inconspicuous in harmony with the surrounding surface layer part, and the appearance of the outer appearance of the packaging container is further improved.

The diameter of each hole of the multiple small holes of the filter portion is preferably a 1.0Mm～7.0Mm. Separation takes time when the diameter is less than 1.0 mm. Exceeds 7.0 mm, noodles, ingredients, solids such as gunpowder may leak from the pores of the filter unit. These multiple small holes may be composed of pores of the same diameter but different diameters (large, medium, small) it is preferred to mix the pores of. According to the latter, further improvement in separation efficiency can be expected.

Wherein it is desired number of multiple small holes in the filter portion is 150 or less 2 5 or more. 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. These multiple small holes, may be regularly arranged, may be irregularly arranged.

The lid has a filter unit made of paper consisting of multiple small holes may be mounted on the back side of the lid. Thus, without piercing the multiple small holes in the lid itself, by adding mounting the filter portion made of paper, it is possible to easily provide a filter unit in the lid.

The separation processing method of the present invention includes a plastic container main body that stores instant foods that are edible by pouring hot water, and a paper lid that covers the upper surface opening of the container main body. A method for separating after-meal and post-meal separation of instant food packaging containers, wherein the lid is separated into a solid and liquid after-meal in a central region excluding its peripheral portion. a filter portion consisting of several small holes, it and a seal portion formed by attaching to the surface side of the lid, after separation of the lid from the container body, and peeling the seal portion, the lid Prepare a conical shape so that the center of the filter part of the body is recessed, and then pour the food content remaining in the container body from above into the recess of this filter part to separate it into solid and liquid, and then the back cover Wrap the solid material separated on the body in a lid to make both combustible waste And it is obtained so as to fractionating the plastic container body as incombustible refuse.

According to fractionation method leftovers and postprandial container instant food packaging container of the present invention, the lid having a filter portion consisting of several small holes in the central region except the peripheral portion from the container body After the separation, the seal part covering the filter part is peeled off, and prepared in a conical shape so that the center of the filter part of the lid is recessed, and then the food remaining in the container body from above in the recess of the filter part Since the contents are poured, the solid and liquid can be separated by a very simple method, and the solid material separated on the top of the lid is combined with a paper lid to form combustible waste, which is a plastic container. There is an effect that the main body can be easily separated as incombustible waste.
