Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food storage container for storing polygonal foods such as a rectangular parallelepiped free cut cake, terrine, roll cake and the like.
[0002]
[Prior art]
In recent years, frozen cakes that do not require cooking have been provided in restaurants such as hotel buffets and pubs. This frozen cake is roughly divided into a so-called torte-shaped individual meal cake and a free-cut cake that has a size of at least two meals and cuts it into an arbitrary size. The
[0003]
6 and 7 show a rectangular free-cut cake and a food storage container for storing the rectangular free-cut cake. The food storage container 1 is covered with a container main body 3 for storing the free-cut cake 2 and the container main body 3. It consists of a lid 4 to be worn.
[0004]
In general, the free cut cake 2 is made by laminating a plurality of biscuits, sponges, creams, mousses, etc., and applying or spraying jelly, creams, mousses, cocoa powders, etc., or topping with powdered sugar, arazan, mimosa, etc. Thus, the decoration layer 2a is formed.
[0005]
The container body 3 is formed to have a bottom with a rectangular bottom plate 3a provided with a pair of long side plates 3b, 3b and a pair of short side plates 3c (one not shown) orthogonal thereto. 4, the top plate 4a, the pair of long side plates 4b, 4b, and the pair of short side plates (not shown) are formed slightly larger than the container body 3 so as to cover the entire container body 3. .
[0006]
[Problems to be solved by the invention]
However, in the food storage container 1 described above, the bottom plate 3a of the container body 3 and the top plate 4a of the lid body 4 are formed with substantially the same dimensions as the free cut cake 2, whereas the long side plate of the container body 3 is used. 3b and the short side plate 3c are formed several millimeters to several centimeters higher than the free cut cake 2 and have a margin between the decoration layer 2a. 2a adheres to the top plate 4a of the lid 4 and impairs the merchantability. In particular, when a highly soluble material such as a jelly with a high sugar content or a cream with a high air content is used for the decoration layer 2a, the decoration layer 2a is a top plate even if the free cut cake 2 is a frozen product. Contact with 4a may cause damage.
[0007]
As a countermeasure, it is conceivable to attach a protective sheet 5 in which a film, a nonwoven fabric, paper or the like is cut in the same shape on the surface of the decoration layer 2a. In this case, the number of parts increases and the cost increases. Or, since it is difficult to mechanically align and put the protective sheet 5 of the same shape on the soft decoration layer 2a, the protective sheet 5 is currently placed manually, which significantly increases productivity. It was detrimental. Further, depending on the type of the protective sheet 5, there are some that are difficult to peel off, and even if the peeling is easy, a part of the decoration layer 2 a adheres to the peeled protective sheet 5 and the surface of the decoration layer 2 a is removed. It has the disadvantage of giving it a messy appearance because of its roughing.
[0008]
The present invention has been made in the background of such circumstances, and the object of the present invention is to provide a food container that can protect food as much as possible from vibration and impact during transportation without using a protective sheet. It is to provide at low cost.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a food container comprising a container body in which a side plate is erected on each outer edge of a polygonal bottom plate, and a lid that is attached to the container body. The upper edge is inclined toward the upper part of the center of the container body, and when the food stored in the container body moves upward, a flap that is in line contact with the upper edge of the food is provided continuously. .
[0010]
Moreover, the bottom plate of the container body may be rectangular or square, and the flaps may be provided on a pair of side pieces facing each other. In this case, chamfers for supporting the flaps can be provided at the upper corners of the other pair of side plates.
[0011]
Furthermore, the folding line parallel to the upper edge of the side plate which this flap continues can also be engraved on the flap. Furthermore, the container body may be made of paper, and the inner surface of the flap may be coated with a water-resistant sheet.
[0012]
The above-described invention can be applied to a container body and a lid body having a triangular shape or more. The container body and the lid body do not necessarily have to be regular polygons, and may have a shape such as a rhombus. The flaps may be provided on all the side plates, but may be provided on a predetermined number of side plates at a ratio of one or two.
[0013]
The flap that is continuous with the side plate is slanted toward the upper center of the container body while being straight or curved, and when the food contained in the container body moves up and down due to vibration or impact during transportation, etc. Receives the upper edge of food and suppresses unwanted movement. In this case, since the flap and the food are in line contact, the damage to the food is suppressed to the minimum only at the upper edge.
[0014]
When the bottom plate of the container body is rectangular or square and the flaps are provided on a pair of opposing side pieces, chamfering the upper corners of the other pair of side plates orthogonal to the pair of side pieces results in a chamfered portion. By placing the flap, the inclination of the flap can be well maintained. As a result, it is possible to more reliably suppress food damage.
[0015]
The number of fold lines engraved on the flap can be arbitrarily determined as required, such as the material and shape of the container body and the flap. Thus, by providing a folding line on the flap, the flap can be kept in a desired inclined state well.
[0016]
Also, if the container body is made of paper and the inner surface of the flap is coated with a water-resistant sheet, the paper-made flap absorbs moisture in the food, freezer or refrigerator and stretches against the inner water-resistant sheet. The entire flap bulges outward and deforms. As a result, the bulge shape of the flap is well maintained, and the food damage is effectively suppressed.
[0017]
Furthermore, the present invention includes a container main body in which a side plate is erected on each outer edge of a polygonal bottom plate, a lid attached to the container main body, and an inner lid that covers the container main body inside the lid. a food container moving, said inner lid has a side plate of a pair of opposed, connect the upper edge of the side plate, and protruding into the central portion above the container body, the food stored in the container body upward When it does, it has the cover part which carries out a line contact with the upper edge of foodstuff, It is characterized by the above-mentioned.
[0018]
The cover part of the inner lid is formed of a curved surface or a flat surface, or both, and is formed in an arbitrary shape such as a circular arc shape, an inverted V shape, or a trapezoidal shape. When moving upward due to vibration or impact, the flap receives the upper edge of the food and suppresses unnecessary movement.
[0019]
