Description

本発明は、茸類や青菜等の生鮮食品を収納するのに適した上部開口の箱型の紙製容器に関するものであり、特に、1枚の紙を折り曲げて、接着剤を貼着する事無く、簡単に組立てることが出来る紙製トレー状容器に係わるものである。 The present invention relates to a box-shaped paper container having an upper opening suitable for storing fresh foods such as potatoes and green vegetables, and in particular, a sheet of paper is folded and an adhesive is applied. It relates to a paper tray-like container that can be easily assembled.

従来、しめじ、えりんぎ等の茸類や青菜等の生鮮食品の包装用容器として、上部開口箱型のプラスチック製や発泡スチロール製のトレー容器が広く使用されている。 2. Description of the Related Art Conventionally, plastic containers such as top-opened box type or styrene foam tray containers have been widely used as packaging containers for fresh foods such as shimeji mushrooms and garlic, and green vegetables.

しかし、プラスチック製トレー容器の廃棄に際して、焼却したときに有毒ガスを発生し環境汚染の原因となる問題点等が指摘されるようになり、廃棄に問題が少なく、環境にやさしい紙を使用した紙製トレー状容器が脚光を浴びるようになっている。
上記の紙製トレー状容器は、一枚乃至、複数枚の紙材を折り曲げ、重合部に接着剤を貼着し、組立てるものが主流である。 However, when plastic tray containers are discarded, toxic gas is generated when incinerated, causing problems such as environmental pollution. Paper that uses environmentally friendly paper with few problems in disposal A tray-shaped container made in the spotlight.
The above-mentioned paper tray-like containers are mainly assembled by folding one or a plurality of paper materials and attaching an adhesive to the overlapping portion.

特開平９−１２４０２８号公報（第5頁、図１，３）特開平１０−１９４２６４号公報（第４頁、図１，２）JP-A-9-1224028 (5th page, FIGS. 1 and 3) JP-A-10-194264 (4th page, FIGS. 1 and 2)

従来のプラスチック製や発泡スチロール製のトレー容器において、容器として使用後の廃棄に問題があるため、現状、使用後、これらのトレー容器は、回収し再利用を図るか、又は燃焼処理するか、等の処理がなされているが、いずれも満足し得る状態でなく、特に、ゴミとして焼却した際に、有毒ガスを発生し環境汚染の原因にもなっており、その使用量の削減等が求められている。
又、プラスチック製のトレー容器を使用した密閉包装内に閉じ込められた生鮮食品から発する水分が、トレー容器の底面に溜まり、水滴化し底面に溜まった水により茸類や青菜等の生鮮食品を品質低下させることがある。 In conventional tray containers made of plastic or polystyrene foam, there is a problem in disposal after use as containers, so at present, after use, these tray containers should be collected and reused or burned, etc. However, none of them are in a satisfactory state, and especially when incinerated as trash, toxic gas is generated and it causes environmental pollution. ing.
In addition, moisture from fresh food confined in sealed packaging using plastic tray containers accumulates on the bottom surface of the tray container and drops into water drops, and the quality of fresh foods such as potatoes and green vegetables deteriorates due to the water remaining on the bottom surface. There are things to do.

紙製トレー容器において、従来のプラスチック製や発泡スチロール製のトレー容器に代わる回収利用、及び、廃棄処理の容易な、環境にやさしい紙製トレー状容器が提案、採用されて来ている。しかし、１枚乃至、複数の紙材を折り曲げ、重合部に接着剤を貼着し、組立てる構造の為、プラスチック製の様に大量に、安価に製作できないため、この紙製トレー容器を、接着剤を貼着する事無く、簡易折り曲げ、組立することにより、材料、製造工程を簡便化することにある。 Paper tray containers have been proposed and adopted as environmentally friendly paper tray containers that are easy to recover and use instead of conventional plastic or polystyrene tray containers. However, it is not possible to produce a large amount of paper like a plastic because of the structure of folding one or more paper materials, attaching an adhesive to the overlapping part, and assembling it. It is to simplify the material and the manufacturing process by simply folding and assembling without sticking the agent.

上記課題を解決するため、この発明は、１枚のみの紙材から折り曲げ、組立てる紙製トレー状容器にあって、底面１の八角形縁に連設した側壁面２、３を起立させ、これら側壁面２に連接する補助側壁片４、端受片５を内側へ折り曲げ、端受片５の端に形成する突起片５Ａ、５Ｂ、５Ｃ、５Ｄを側壁面３上の切込み３Ａ、３Ｂ、３Ｃ、３Ｄに差込み、係合連結させ、貼着等を行うことなく、1枚の紙から手組みで簡単に組立てられるようにしたものである。
In order to solve the above-mentioned problems, the present invention is a paper tray-like container that is folded and assembled from only one sheet of paper, and the side wall surfaces 2 and 3 connected to the octagonal edge of the bottom surface 1 are erected. auxiliary side wall piece 4 which connects the side wall surface 2, bending the edge receiving member 5 inwardly projecting pieces 5A forming the end of the end receiving piece 5, 5B, 5C, 5D and the side wall surface 3 of the notch 3A, 3B, 3C It is designed to be easily assembled by hand from a single piece of paper without being inserted into 3D, engaged and connected, and attached.

本発明は次のような効果がある。
１．この発明の紙製容器は、一枚の紙材のみを使用し、工程の少ない一連の折り曲げ作業で、接着剤を貼着すること無く、簡単に、確実に、紙製トレー状容器を組立てる事ができ材料費、組立費のコストを低減される。 The present invention has the following effects.
1. The paper container according to the present invention uses only one sheet of material, and can assemble a paper tray-like container simply and reliably without sticking adhesive by a series of folding operations with few steps. The cost of materials and assembly can be reduced.

２．この発明の紙製容器は、１枚の紙材のみで構成される容器である事から、容器としての使用後、そのまま燃焼ゴミとして廃却する事ができ、環境汚染等の原因にならないものである。又、省資源省エネルギーのために廃棄物を回収し紙資源として再利用できる点でも効果が高いものである。 2. Since the paper container of the present invention is a container composed of only one sheet of paper, it can be discarded as combustion waste after use as a container and does not cause environmental pollution. is there. In addition, it is highly effective in that waste can be collected and reused as paper resources for resource saving and energy saving.

３．本発明の紙製容器は、紙製の容器である事から、密閉包装容器で茸類や青菜等の生鮮食品から蒸発する水分が水滴化して容器の底面に付着し、底面に落ちて水滴化した水分を紙で吸収し、紙容器の側面や底面に水が溜まる事がないため、生鮮食品の品質低下を防ぐことができ、生鮮食品の包装用紙製容器として、使用範囲を広げることができる。 3. Since the paper container of the present invention is a paper container, the moisture evaporating from fresh foods such as potatoes and greens in the sealed packaging container drops into water droplets and adheres to the bottom surface of the container and falls to the bottom surface to form water droplets. Since the absorbed moisture is absorbed by the paper and water does not accumulate on the side or bottom of the paper container, it can prevent the quality of fresh food from deteriorating and can be used as a packaging container for fresh food. .
