本考案はトレータイプの容器に関し、特に鋏等により容
易に開封し得るトレータイプの容器に関する。[Detailed Description of the Invention] The present invention relates to a tray-type container, and particularly to a tray-type container that can be easily opened with scissors or the like.
従来よりカレー、シチュー等の容器としてトレータイプ
のレトルト容器が知られ、かかる容器は使用時に当って
熱湯内に投入加熱するので、材質的にも丈夫な材料が用
いられ、又ヒートシール部の強度のあるヒートシールが
なされる。Tray-type retort containers have traditionally been known as containers for curry, stew, etc., and since such containers are heated by being placed in boiling water during use, durable materials are used, and the strength of the heat-sealed portion is high. A certain amount of heat sealing is done.
従ってその開封は鋏等により端部を切開して行なわれる
が、第３図に示すように従来のトレータイプのレトルト
容器は容器本体１０１は周縁のフランジ部１０２と、そ
の内側で下方に突出した内容物収納部分１０３とからな

されているため、開封部分１０８が内容物によりふくれ
ているので開封が困難であった。Therefore, the seal is opened by cutting the end with scissors or the like, but as shown in FIG. Since the lid material 110 is heat-sealed to the flange portion 102 of the container, the opening portion 108 is swollen by the contents, making it difficult to open the container.
本考案は上記点に鑑み、容器本体の形状を改良すること
により、開封部分の内容物をなくし若しくは極めて少な

トレータイプ容器である。The structure of the present invention is that the container body is formed into a tray shape, has a flat flange around its periphery, and has a side wall and a bottom wall extending inside the flange. A content storage portion is formed, and a portion of the inner side of the flange portion is connected to the side wall via a cut surface that is a flat surface convex toward the center of the content storage portion, and the flange portion of the container body is connected to the side wall. This is an easy-to-open tray-type container with a sealed flat lid.

されている。This content storage part 3 has a bottom wall 31 and a side wall 32 that is inclined toward the center, and the upper end of the side wall 32 is connected to the flange part 2, and a part of the side wall 32 is connected to the upper end of the side wall 32. 32' is not connected directly to the flange part 2', but is connected to the flange part 2' through a flat cut surface 4 provided so that the flange part 2' extends toward the center of the contents storage part 3. has been done.
本実施例においてはこの切開面４の平面形状がフランジ
部２′の角の点ｇ、ｈと頂点ｄを結ぶ円弧状である。In this embodiment, the planar shape of the cut surface 4 is an arc connecting the corner points g and h of the flange portion 2' and the apex d.

る。Next, the lid material 10 and the heat-sealed portion 11 of the container body 1 are the portions shown by the grid lines in FIG. However, the portion of the flange portion 2' connected to the cut surface 4 is heat-sealed 11' on the outside of the straight line f connecting points C and e, which are the extensions of the arcs of points g, d, and h, as described above. shall be taken as a thing.
ここで鋏等により切開されるべき線８は蓋材１０にその
旨の表示がされており、好ましくはフランジ部り′上の
未シール部に設けることとし、第２図においては点りと
Ｃの間に設けることとす。Here, the line 8 to be cut with scissors or the like is marked on the lid member 10, and is preferably provided on the unsealed part of the flange. It will be set up between.

記容器本体１とヒートシール可能な材料が選ばれる。The lid material 10 is made of, for example, polyethylene terephthalate (hereinafter P
ET)/A I /CPP, nylon (hereinafter abbreviated as nylon)/A I /CPP, etc., is a flat composite layer material having heat resistance and gas barrier properties, with PET on the front side, A design is applied to the film such as NY by back printing or the like, and a material such as CPP that can be heat-sealed to the container body 1 is selected for the film serving as the inner surface.
そして切開線８対応位置には図示していないが、かかる
切開線８に沿って切開すべき旨の表示がなされている。Although not shown at a position corresponding to the incision line 8, there is a display indicating that the incision should be made along the incision line 8.
本考案は以上の如き構成であって、その特色とするとこ
ろは容器本体１の切開線８を平坦なフランジ部２′にす
ると共に、そのフランジ部２から内容物収納部分３の中
心に向って凸な平面である切開面４が連設されているこ
とである。The present invention has the above-mentioned structure, and its characteristics are that the incision line 8 of the container body 1 is made into a flat flange part 2', and the incision line 8 of the container body 1 is made into a flat flange part 2', and the incision line 8 of the container body 1 is made into a flat flange part 2'. The cutting surfaces 4, which are convex planes, are arranged in a row.
即ち、前記切開面４を内容物収納部分３の中心に向って
凸に形成したことにより、平坦若しくは外側に凸な切開
面を設けたときには内圧によりその中心から下向きに変
形して、切開面４と蓋材１０の間に内容物が入りやすい
のに較べて、たとえ変形したとしても上側に向って変形
するので切開面４と蓋材１０との間はさらに密接するの
で、結果的に内容物が入りに＜＜、従って本トレータイ
プ容器は切開に当って切開し易く、内容物が外に出てし
まうことが少ないという利点がある。That is, by forming the incision surface 4 convexly toward the center of the content storage portion 3, when a flat or outwardly convex incision surface is provided, the incision surface 4 deforms downward from the center due to internal pressure. Although it is easy for the contents to enter between the incision surface 4 and the lid material 10, even if it is deformed, it will deform upwards, so the incision surface 4 and the lid material 10 will be in closer contact with each other, and as a result, the contents will not be able to enter. Therefore, this tray type container has the advantage that it is easy to cut open and the contents are less likely to come out.
