Description

本発明は板に複数の凹状の収容部を形成したトレイに関する。 The present invention relates to a tray in which a plurality of concave accommodating portions are formed on a plate.

従来より、複数の冷凍食品等を個別に収容すべく板に凹状の収容部を複数形成したトレイが知られている（例えば、特許文献１参照）。近年では、このようなトレイにおいて、各収容部を個々に切り離し可能とすべく、収容部同士を連結する連結部にミシン目が入れられる場合がある。そして、連結部にミシン目を入れると、連結部の強度が低下してトレイが連結部で折れ曲がりやすくなるため、連結部に対してミシン目に直交する方向に延びる断面凹状又は凸状のリブを設ける場合が多い。
特開平１０−１５７７２０号公報 2. Description of the Related Art Conventionally, there is known a tray in which a plurality of concave storage portions are formed on a plate so as to individually store a plurality of frozen foods and the like (for example, see Patent Document 1). In recent years, in such a tray, a perforation may be provided in a connecting portion that connects the receiving portions so that the receiving portions can be individually separated. When the perforation is made in the connecting portion, the strength of the connecting portion is reduced and the tray is easily bent at the connecting portion.Therefore, a concave or convex rib extending in the direction perpendicular to the perforation with respect to the connecting portion is provided. Often provided.
JP-A-10-157720

このようなトレイは、通常次のような工程により製造される。まず、樹脂板を加熱しながら型押しして複数の収容部を形成すると共に収容部間の連結部にリブを形成してトレイとする。続いて、ミシン目に対応する凹凸刃を有する長尺のミシン目形成用刃と、定盤とで、トレイの連結部及びリブを挟むことにより、連結部及びリブにミシン目を形成する。 Such a tray is usually manufactured by the following process. First, the resin plate is embossed while being heated to form a plurality of accommodating portions, and ribs are formed at connecting portions between the accommodating portions to form a tray. Subsequently, a perforation is formed in the connection portion and the rib by sandwiching the connection portion and the rib of the tray with a long perforation forming blade having an uneven blade corresponding to the perforation and a surface plate.

この場合、断面凹状又は断面凸状のリブはミシン目形成用刃と定盤との間でつぶされ、このようにしてつぶされた状態でリブやリブと連結部との接点部にミシン目が形成される。したがって、リブ内や、リブと連結部との接点部においてミシン目が精度良く形成できない場合があることが判明した。具体的には、このミシン目は、切断部及び非切断部が交互に配置されてなるが、非切断部の長さ等の精度が低下しやすい。そして、ミシン目の精度が低下した場合、ミシン目に沿って収容部を切り離しにくくなったり、意図せずに収容部が切り離されてしまったりする場合がある。 In this case, the rib having a concave cross section or a convex cross section is crushed between the perforation forming blade and the surface plate, and in such a crushed state, a perforation is formed at the contact portion between the rib or the rib and the connecting portion. It is formed. Therefore, it has been found that the perforation may not be formed with high accuracy in the rib or in the contact portion between the rib and the connecting portion. Specifically, the perforation is formed by alternately arranging cut portions and non-cut portions, but accuracy such as the length of the non-cut portions is likely to decrease. And when the precision of a perforation falls, it may become difficult to isolate | separate an accommodating part along a perforation, or an accommodating part may be disconnected unintentionally.

本発明は上記課題に鑑みてなされたものであり、ミシン目が精度良く形成されたトレイを提供することを目的とする。 The present invention has been made in view of the above problems, and an object thereof is to provide a tray having perforations formed with high accuracy.

本発明にかかるトレイは、板に凹状の収容部を複数形成した樹脂製のトレイであって、収容部同士を連結する連結部には、連結部に沿って、切断部及び非切断部を交互に配したミシン目が形成されており、連結部には、さらに、ミシン目に対して交差し、かつ、一方の収容部から他方の収容部まで延び、かつ、断面が凹状のリブが設けられ、リブ内、及び、リブと連結部との接点部にはミシン目の非切断部が設けられていない。 The tray according to the present invention is a resin-made tray in which a plurality of concave accommodating portions are formed on a plate, and the cutting portion and the non-cutting portion are alternately arranged along the connecting portion in the connecting portion connecting the receiving portions. The connecting portion is further provided with a rib that intersects the perforation and extends from one housing portion to the other housing portion and has a concave cross section. In the ribs, and at the contact portions between the ribs and the connecting portions, there are no perforated uncut portions.

本発明のトレイによれば、リブ内及びこのリブと連結部との接点部にはミシン目の非切断部がない。したがって、このトレイにおいて、ミシン目の非切断部は、リブ内及びリブと連結部との接点部以外の連結部に形成されている。そして、このリブ内及びリブと連結部との接点部以外の連結部は、ミシン目の形成時にミシン目形成用の刃によって大きく変形されず、よけいな応力がかからない。したがって、このようなトレイにおいては、ミシン目の非切断部の長さや形状の精度が高い。これにより、各収容部をこのミシン目に沿って好適に切り取ることが可能となる。 According to the tray of the present invention, there is no perforated uncut portion in the rib and in the contact portion between the rib and the connecting portion. Therefore, in this tray, the non-cut portion of the perforation is formed in the connecting portion other than the contact portion between the rib and the connecting portion. The connecting portions other than the contact portions between the ribs and the connecting portions of the ribs are not greatly deformed by the perforation forming blades when forming the perforations, and no excessive stress is applied. Therefore, in such a tray, the accuracy of the length and shape of the non-cut portion of the perforation is high. Thereby, it becomes possible to cut off each accommodating part suitably along this perforation.

また、本発明では、リブが断面凹状、すなわち、収容部と同じ向きに凸になるように形成されている。したがって、一方の収容部を支持し、他方の収容部を支持しない状態とし、他方の収容部がこの収容部内の収容物の重力により垂れ下がろうとする場合に、リブには、リブの伸びる方向に沿って圧縮力が働くこととなり、切断部の端面同士が押し合って連結部の折れ曲がりを抑制する効果を発揮する。 Further, in the present invention, the rib is formed to have a concave cross section, that is, to protrude in the same direction as the accommodating portion. Therefore, when the one accommodating portion is supported and the other accommodating portion is not supported, and the other accommodating portion tends to hang down due to the gravity of the contents in the accommodating portion, the rib has a direction in which the rib extends. A compressive force will work along, and the end surfaces of a cutting part will press against each other, and the effect which suppresses the bending of a connection part will be exhibited.

ここで、本発明のトレイにおいては、板に対して複数の収容部がｎ行ｍ列のマトリクス状（ｎ，ｍは２以上の整数）に並ぶように形成され、収容部同士を連結する連結部には、マトリクスの行方向及びマトリクスの列方向に沿ってそれぞれミシン目が形成され、連結部において４つの収容部を連結する交差部には、リブが一対形成され、これら一対のリブは互いに交差し、これら一対のリブのそれぞれが行方向に沿うミシン目及び列方向に沿うミシン目に交差することが好ましい。 Here, in the tray of the present invention, a plurality of receiving portions are formed so as to be arranged in a matrix of n rows and m columns (n and m are integers of 2 or more) with respect to the plate, and the connecting portions are connected to each other. In the section, perforations are formed along the row direction of the matrix and the column direction of the matrix, respectively, and a pair of ribs are formed at the intersections connecting the four accommodating portions in the connecting portion. It is preferable that each of the pair of ribs intersect each other at the perforation along the row direction and at the perforation along the column direction.

このように収容部がマトリクス状に配置されたトレイにおいては、各収容部を容易に分離すべく連結部の交差部に十字状に切断部を形成する必要がある。そこで、この交差部に、互いに交差する一対のリブを設けることにより、本発明の如きミシン目の非切断部を有さないリブを好適に設けることができる。 Thus, in the tray in which the accommodating portions are arranged in a matrix, it is necessary to form a cut portion in a cross shape at the intersection of the connecting portions in order to easily separate the accommodating portions. Therefore, by providing a pair of ribs that intersect each other at the intersecting portion, it is possible to suitably provide a rib that does not have a non-cut portion of the perforation as in the present invention.

本発明によれば、ミシン目が精度良く形成されたトレイが提供される。 According to the present invention, a tray in which perforations are formed with high accuracy is provided.

以下、図１及び図２を参照しながら、本発明の実施の形態に係るトレイについて説明する。図１はトレイの斜視図、図２は図１のトレイ１のＩＩ部分の拡大上面図である。本実施形態のトレイ１は、図１に示すように、板１に対して収容物を収容可能な複数個の収容部２をｎ個×ｍ個（ｎ、ｍは２以上の整数）マトリクス状に並べて形成したものである。本実施形態では、一例として、３個×２個のマトリクスである。 Hereinafter, a tray according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. 1 is a perspective view of the tray, and FIG. 2 is an enlarged top view of a portion II of the tray 1 in FIG. As shown in FIG. 1, the tray 1 of the present embodiment has a matrix shape of a plurality of accommodating portions 2 that can accommodate an object with respect to the plate 1 (n and m are integers of 2 or more). These are formed side by side. In the present embodiment, as an example, a matrix of 3 × 2 is used.

各収容部２は、所定の深さを有する凹状形状を呈している。また、各収容部２の縁同士は、連結部３によってそれぞれ連結されている。 Each accommodating portion 2 has a concave shape having a predetermined depth. Further, the edges of the accommodating portions 2 are connected to each other by a connecting portion 3.

具体的には、連結部３は、Ｘ方向に延びる横連結部３ａと、Ｙ方向に延びる縦連結部３ｂとを有している。横連結部３ａと縦連結部３ｂとは、互いに交差して交差部３ｃを形成している。交差部３ｃは、４つの収容部２を連結している。 Specifically, the connecting portion 3 includes a horizontal connecting portion 3a extending in the X direction and a vertical connecting portion 3b extending in the Y direction. The horizontal connecting portion 3a and the vertical connecting portion 3b intersect with each other to form an intersecting portion 3c. The intersecting portion 3 c connects the four accommodating portions 2.

横連結部３ａは、収容部２同士をＸ方向に連結し、縦連結部３ｂは収容部２同士をＹ方向に連結し、交差部３ｃはこの交差部３ｃを取り囲む４つの収容部２を連結している。 The horizontal connecting portion 3a connects the receiving portions 2 in the X direction, the vertical connecting portion 3b connects the receiving portions 2 in the Y direction, and the intersecting portion 3c connects the four receiving portions 2 surrounding the intersecting portion 3c. is doing.

横連結部３ａには各横連結部３ａに沿ってＸ方向に延びるミシン目１０が一端から他端まで形成され、縦連結部３ｂには縦連結部３ｂに沿ってＹ方向に延びるミシン目１１が一端から他端まで形成されている。 A perforation 10 extending in the X direction along each horizontal connection portion 3a is formed in the horizontal connection portion 3a from one end to the other end, and a perforation 11 extending in the Y direction along the vertical connection portion 3b is formed in the vertical connection portion 3b. Is formed from one end to the other end.

ミシン目１０は、図２に示すように、Ｘ方向に沿って所定長さに亘って切断された切断部１０ａと、Ｘ方向に沿って所定長さに亘って切断せずに連結している非切断部１０ｂと、が交互に配置されてなる。また、ミシン目１１は、Ｙ方向に沿って所定長さに亘って切断された切断部１１ａと、Ｙ方向に沿って所定長さに亘って切断せずに連結している非切断部１１ｂとが交互に配置されてなる。非切断部１０ｂがミシン目１０を挟んだ両側の連結部３ａ同士を結合し、非切断部１１ｂがミシン目１１を挟んだ両側の連結部３ｂ同士を結合している。ミシン目１０，１１は、連結部３の交差部３ｃで互いに直交している。 As shown in FIG. 2, the perforation 10 is connected to a cutting portion 10 a cut along a predetermined length along the X direction without cutting along a predetermined length along the X direction. The non-cut portions 10b are alternately arranged. The perforation 11 includes a cut portion 11a cut along a Y direction along a predetermined length, and a non-cut portion 11b connected without cutting along a Y length along a predetermined length. Are arranged alternately. The uncut portion 10b joins the connecting portions 3a on both sides sandwiching the perforation 10, and the uncut portion 11b joins the connecting portions 3b on both sides sandwiching the perforation 11. The perforations 10 and 11 are orthogonal to each other at the intersecting portion 3 c of the connecting portion 3.

そして、連結部３には、図１に示すように、十字リブ５と、折線リブ７ａ，７ｂが形成されている。具体的には、図１及び図２に示すように、十字リブ５は連結部３の交差部３ｃに形成され、互いに交差する直線リブ５ａ，直線リブ５ｂを有する。直線リブ５ａ，５ｂは互いにほぼ直交している。直線リブ５ａ，５ｂは、それぞれ斜向かいの位置にある収容部２同士を結ぶように、交差部３ｃの一端から他端までに亘って設けられている。さらに、直線リブ５ａ，５ｂは、それぞれ、ミシン目１０及びミシン目１１に対して約４５°の角度をなすように斜めに交差している。 As shown in FIG. 1, the connecting portion 3 is formed with a cross rib 5 and broken line ribs 7a and 7b. Specifically, as shown in FIGS. 1 and 2, the cross rib 5 is formed at an intersecting portion 3 c of the connecting portion 3, and includes a straight rib 5 a and a straight rib 5 b that intersect each other. The straight ribs 5a and 5b are substantially orthogonal to each other. The straight ribs 5a and 5b are provided from one end to the other end of the intersecting portion 3c so as to connect the accommodating portions 2 located obliquely opposite each other. Further, the straight ribs 5a and 5b cross each other obliquely so as to form an angle of about 45 ° with respect to the perforation 10 and the perforation 11, respectively.

これらの直線リブ５ａ，５ｂは、図１に示すように、断面が半円形状を呈し、収容部２と同じ向きの凹状、すなわち下向きに凸に形成されている。 As shown in FIG. 1, these linear ribs 5 a and 5 b have a semicircular cross section, and are formed in a concave shape in the same direction as the housing portion 2, that is, convex downward.

一方、図１に示すように、折線リブ７ａは、横連結部３ａの両端部に、折線リブ７ｂは、縦連結部３ｂの両端部にそれぞれ形成されている。 On the other hand, as shown in FIG. 1, the fold line rib 7a is formed at both ends of the horizontal connection portion 3a, and the fold line rib 7b is formed at both ends of the vertical connection portion 3b.

折線リブ７ａは、ミシン目１０に交差するように横連結部３ａを横切っている。より詳しくは、折線リブ７ａは、横連結部３ａを挟んで隣り合う一対の収容部２同士を結ぶように形成されている。 The broken line rib 7a crosses the horizontal connecting portion 3a so as to intersect the perforation 10. More specifically, the fold line rib 7a is formed so as to connect a pair of adjacent accommodating portions 2 with the lateral coupling portion 3a interposed therebetween.

折線リブ７ｂは、ミシン目１１を交差するように縦連結部３ｂを横切っている。より詳しくは、折線リブ７ｂは、縦連結部３ｂを挟んで隣り合う一対の収容部２同士を結ぶように形成されている。 The broken line rib 7b crosses the vertical connecting portion 3b so as to cross the perforation 11. More specifically, the fold line rib 7b is formed so as to connect a pair of adjacent accommodating portions 2 with the vertical coupling portion 3b interposed therebetween.

さらに詳しくは、折線リブ７ａ，７ｂは、トレイ１００を平面視、すなわち、トレイ１００に直交する方向から見た時に、折線リブ７ａ、７ｂの中心軸がミシン目１０、ミシン目１１で折れ曲がるように、より具体的には、トレイ１００の外側を向くように折れ曲がる山形形状とされている。 More specifically, the fold line ribs 7 a and 7 b are bent so that the central axes of the fold line ribs 7 a and 7 b are bent at the perforation 10 and the perforation 11 when the tray 100 is viewed in plan view, that is, from the direction orthogonal to the tray 100. More specifically, the shape is a mountain shape that is bent so as to face the outside of the tray 100.

また、折線リブ７ａ，７ｂの断面形状は、直線リブ５ａ、５ｂと同様に断面半円で凹状すなわち、下向き凸とされている。 Further, the cross-sectional shapes of the broken line ribs 7a and 7b are concave in a semicircular cross section, that is, downwardly convex like the straight ribs 5a and 5b.

そして、本実施形態に係るトレイ１００においては、例えば、図２に示すように、直線リブ５ａ，５ｂの内部、及び、直線リブ５ａ，５ｂと横連結部３ａや縦連結部３ｂとの接点部３ｄには、ミシン目１０、１１の非切断部１０ｂ，１１ｂが形成されていない。すなわち、直線リブ５ａ，５ｂの内部、及び、直線リブ５ａ，５ｂと横連結部３ａや縦連結部３ｂとの接点部３ｄには、ミシン目１０の切断部１０ａのみが形成されている。 In the tray 100 according to the present embodiment, for example, as shown in FIG. 2, the inside of the straight ribs 5a and 5b and the contact portion between the straight ribs 5a and 5b and the horizontal connecting portion 3a or the vertical connecting portion 3b. In 3d, the non-cut portions 10b and 11b of the perforations 10 and 11 are not formed. That is, only the cut part 10a of the perforation 10 is formed in the linear ribs 5a and 5b and in the contact part 3d between the linear ribs 5a and 5b and the horizontal connection part 3a and the vertical connection part 3b.

同様にして、折線リブ７ａの内部、及び、折線リブ７ａと横連結部３ａとの接点部３ｅ、並びに、折線リブ７ｂの内部、及び、折線リブ７ｂと縦連結部３ｂとの接点部（図示省略）においても、ミシン目の非切断部１０ｂ、１１ｂが形成されて折らず、ミシン目の切断部１０ａのみが形成されている。 Similarly, the inside of the broken line rib 7a, the contact part 3e between the broken line rib 7a and the lateral coupling part 3a, and the inside of the broken line rib 7b and the contact part between the folded line rib 7b and the vertical coupling part 3b (illustrated). Even in the case of omission), the perforated uncut portions 10b and 11b are formed and not broken, and only the perforated cut portion 10a is formed.

このようなトレイ１００は、次のようにして製造することができる。まず、樹脂等の板状部材を加熱しながら所定の型に挟んで、収容部２、連結部３、直線リブ５ａ，５ｂ、折線リブ７ａ，７ｂを形成してトレイとする。その後、横連結部３ａ及び縦連結部３ｂに沿って延びるミシン目形成用刃と定盤との間に、このトレイの直線リブ５ａ，５ａ及び折線リブ７ａ，７ａを含む横連結部３ａ及び縦連結部３ｂを挟み込み、直線リブ５ａ，５ｂ及び折線リブ７ａ，７ｂをつぶしつつ、横連結部３ａ及び縦連結部３ｂにミシン目１０，１１を形成すればよい。なお、本トレイ１００の素材としては、ＰＰ、ＰＥ、ＰＳ、Ａ−ＰＥＴ、ＯＰＳ、ＰＰ−Ｆ、ＰＣ等の樹脂を任意好適に使用できる。 Such a tray 100 can be manufactured as follows. First, a plate-shaped member such as resin is sandwiched between predetermined molds while being heated, and the accommodating portion 2, the connecting portion 3, the straight ribs 5a and 5b, and the broken line ribs 7a and 7b are formed into a tray. Thereafter, the horizontal connecting portion 3a including the straight ribs 5a, 5a and the folding line ribs 7a, 7a of the tray between the perforated blades extending along the horizontal connecting portion 3a and the vertical connecting portion 3b and the surface plate, and the vertical connecting portion 3a. The perforations 10 and 11 may be formed in the horizontal connecting portion 3a and the vertical connecting portion 3b while sandwiching the connecting portion 3b and crushing the straight ribs 5a and 5b and the broken line ribs 7a and 7b. In addition, as materials for the main tray 100, resins such as PP, PE, PS, A-PET, OPS, PP-F, and PC can be arbitrarily used.

続いて、本実施形態に係るトレイ１００の作用効果について説明する。 Then, the effect of the tray 100 which concerns on this embodiment is demonstrated.

本実施形態のトレイ１００では、直線リブ５ａ，５ｂ内、及び、折線リブ７ａ，７ｂ内、並びに、直線リブ５ａ，５ｂや折線リブ７ａ，７ｂと横連結部３ａや縦連結部３ｂとの接点部３ｄ，３ｅにはミシン目１０，１１の非切断部１０ｂが形成されてない。すなわち、ミシン目１０，１１の形成時に形状がつぶされてしまう直線リブ５ａ，５ｂ内、折線リブ７ａ，７ｂ内、さらにその近傍には、ミシン目の切断部１０ａ，１１ａのみが形成されている。 In the tray 100 of the present embodiment, the straight ribs 5a and 5b, the fold line ribs 7a and 7b, and the straight ribs 5a and 5b and the fold line ribs 7a and 7b and the contact points between the horizontal connection part 3a and the vertical connection part 3b. The non-cut portions 10b of the perforations 10 and 11 are not formed in the portions 3d and 3e. That is, only the perforated cut portions 10a and 11a are formed in the straight ribs 5a and 5b, the broken line ribs 7a and 7b, and the vicinity thereof, whose shapes are crushed when the perforations 10 and 11 are formed. .

したがって、このトレイ１００において、ミシン目１０の非切断部１０ｂ，１１ｂは、ミシン目１０，１１の形成時につぶされずによけいな応力がかからない部分にのみ形成されている。したがって、ミシン目１０，１１の非切断部１０ｂ，１１ｂの長さや形状の精度が高い。したがって、トレイ１００から各収容部２をこのミシン目１０，１１に沿って好適に切り取ることができる。また、意図せずに、各収容部２がトレイ１００から切り離されてしまうことが起きにくい。 Therefore, in this tray 100, the non-cut portions 10b and 11b of the perforation 10 are formed only in the portions that are not crushed when the perforations 10 and 11 are formed and do not receive any significant stress. Therefore, the accuracy of the length and shape of the uncut portions 10b and 11b of the perforations 10 and 11 is high. Therefore, each accommodating part 2 can be suitably cut out from the tray 100 along the perforations 10 and 11. In addition, it is difficult for the storage units 2 to be separated from the tray 100 unintentionally.

また、本実施形態のトレイ１００では、直線リブ５ａ，５ｂ及び折線リブ７ａ，７ｂが断面凹状、すなわち、収容部２と同様に下に凸になるように形成されている。したがって、連結された収容部２の何れかを支持した時に、保持されない収容部２が、収容部２内の内容物の重さにより垂れ下がろうとする場合に、この直線リブ５ａ，５ｂや折線リブ７ａ，７ｂには、リブが延びる方向に沿って圧縮力が働くこととなる。すなわち、直線リブ５ａ，５ｂや折線リブ７ａ，７ｂの切断部１０ａ，１１ａにおいて、端面同士が押し合うこととなる。 Further, in the tray 100 of the present embodiment, the straight ribs 5a and 5b and the folding line ribs 7a and 7b are formed to have a concave cross section, that is, to protrude downward similarly to the housing portion 2. Therefore, when the storage part 2 that is not held when supporting any of the connected storage parts 2 tends to hang down due to the weight of the contents in the storage part 2, the linear ribs 5a and 5b and the broken line A compressive force acts on the ribs 7a and 7b along the extending direction of the ribs. That is, the end surfaces are pressed against each other at the cut portions 10a and 11a of the straight ribs 5a and 5b and the broken line ribs 7a and 7b.

したがって、直線リブ５ａ，５ｂや折線リブ７ａ，７ｂ内、直線リブ５ａ，５ｂや折線リブ７ａ，７ｂと横連結部３ａや縦連結部３ｂとの接点部が完全に切断された状態でも、これらのリブは、横連結部３ａや縦連結部３ｂの強度を強めて折れ曲がりにくくする効果を十分に発揮する。 Therefore, even in the state where the contact portions between the straight ribs 5a and 5b and the broken line ribs 7a and 7b, the straight ribs 5a and 5b and the broken line ribs 7a and 7b, and the horizontal connecting part 3a and the vertical connecting part 3b are completely cut. This rib sufficiently exhibits the effect of increasing the strength of the horizontal connecting portion 3a and the vertical connecting portion 3b and making it difficult to bend.

さらに、本実施形態においては、直線リブ５ａ，５ｂが互いに交差しつつ、連結部３の交差部３ｃに形成されている。この交差部３ｃには、収容部２同士を切り離しやすくすべく、十字状に切断部１０ａ，１１ａを形成する必要があるので、この交差部３ｃは本実施形態の如き非切断部を有さないリブを形成する場所として好適である。 Furthermore, in the present embodiment, the linear ribs 5a and 5b are formed at the intersecting portion 3c of the connecting portion 3 while intersecting each other. Since it is necessary to form the cut portions 10a and 11a in a cross shape so that the accommodating portions 2 can be easily separated from each other in the intersecting portion 3c, the intersecting portion 3c does not have an uncut portion as in this embodiment. It is suitable as a place for forming a rib.

このようなトレイ１００は、唐揚げ等の冷凍食品、菓子等の固形状食品、ジャム等の流動性食品等の食品を個別に収容することができ、食品を収容したままトレーから収容部を個々に分離することができる。また、食品以外の物品を収容することも可能である。 Such a tray 100 can individually store food such as frozen food such as deep-fried food, solid food such as confectionery, and fluid food such as jam. Can be separated. It is also possible to accommodate articles other than food.

なお、本発明は上記実施形態に限定されず様々態様が可能である。 In addition, this invention is not limited to the said embodiment, A various aspect is possible.

例えば、上記実施形態では、直線リブ５ａ，５ｂ、折線リブ７ａ，７ｂの断面形状は、半円形に限らず、矩形、正方形、台形、楕円形、Ｖ字（三角）型、円形等限定されず、下向きに凸であれば任意である。 For example, in the above-described embodiment, the cross-sectional shapes of the straight ribs 5a and 5b and the broken line ribs 7a and 7b are not limited to a semicircular shape, but are not limited to a rectangular shape, a square shape, a trapezoidal shape, an elliptical shape, a V-shaped (triangular) shape, a circular shape, or the like. If it is convex downward, it is optional.

また、収容部２の形状も、箱形形状に限らず、半球状、三角柱状等が可能である。 Further, the shape of the accommodating portion 2 is not limited to the box shape, and may be a hemispherical shape, a triangular prism shape, or the like.

また、収容部のｎ×ｍ（ｎ行ｍ列）のマトリクスにおいて、ｎ、ｍは、それぞれ、２以上の整数であれば特に限定されない。 Further, in the n × m (n rows and m columns) matrix of the accommodating portion, n and m are not particularly limited as long as each is an integer of 2 or more.
