JP2001186840A - Mat and case for heating food - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a mat and case for heating easily producible and capable of giving throughly baking effect with hard palate feeling. SOLUTION: This mat is so designed that a plurality of through holes 3 are set on a sheet-like base material 2, and upward projections 4 and downward projections 5 set on the periphery of the through holes 3 respectively, to secure spaces between the base material 2 and a confectionery dough, and between the base material 2 and e.g. a pan on which the mat 1 is put, and make e.g. steam issued from the confectionery dough while baked easily escape, and thus attain a hard through baking. The other objective case is such one as to be furnished with through holes and projections, similar to those of the mat 1, on the bottom wall.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rug and a container used for heating and baking cakes and pizzas.

[0002]

2. Description of the Related Art For example, when a pasty confectionery material is filled in an aluminum foil molded container having a corrugated peripheral wall and baked,
A so-called cupcake is obtained. In order to heat the whole confectionery dough evenly and efficiently during this baking, it has been proposed to provide a through hole in the bottom of the container (No. 29608).
No. 77 patent publication). However, when the forming containers are arranged in a pan to be loaded into an oven or the like, the bottom of the forming container is in close contact with the bottom surface of the pan and almost no voids are present, and steam or moisture generated from the dough stays and some types of dough remain. Hard surface baked products required for foods such as pizza cannot be obtained.

[0003]

Therefore, for example, Japanese Patent No. 2984900 proposes forming a projection provided with a through hole on the upper surface of the bottom of a heating container. However, when such a container is also placed on the pan, the bottom surface adheres to the pan, and there is no escape for steam. It is also disclosed that legs are provided on the outer surface of the bottom, but a thin and easily foldable material such as aluminum foil or paper has little effect of letting the bottom float and letting out steam or the like.

In addition, it is difficult to form a conical or pyramidal projection, and it is very difficult to form a hole in the inclined surface.

Accordingly, an object of the present invention is to provide a heating rug and a container which can be easily manufactured by using a thin and flexible material and which can obtain a hard textured finish.

[0006]

In order to solve the above-mentioned problems, in the food heating rug of the present invention, a plurality of through holes are provided in a sheet-like heat-resistant base material, and an upward projection and a downward projection are formed on the periphery of these through holes. Either or both of the projections are provided to create a gap on both surfaces of the substrate.

[0007] In the food heating container of the present invention, a plurality of through holes are provided in the bottom wall, and either or both of the upward projection and the downward projection are provided on the periphery of the through hole, and a gap is provided on both surfaces of the bottom wall. It was made to happen.

It is preferable that the through hole is formed in a slit shape, and it is preferable to form an upward projection and a downward projection along a long side of the slit.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a rug 1 of the present invention has a sheet-like base material 2 provided with a large number of through holes 3, and a projection 4 rising from the periphery of the hole 3 and a projection 5 projecting downward. It is. These projections 4 and 5 are shown in FIG.
As shown in (a), it may be provided on the periphery of the same hole 3,
Alternatively, as shown in FIG. 1 (b), only one protrusion 3 may be provided in one hole 3 and only a protrusion 5 may be provided in another adjacent hole 3. Further, it is preferable that the projections 4 are formed at substantially the same height as a whole, and the projections 5 are formed at substantially the same height as a whole. The base material 2
May be a simple substance such as a metal foil such as aluminum, heat-resistant paper, a heat-resistant synthetic resin film or sheet, or a laminate thereof.

In order to form the holes 4 and 5, it is preferable to use cutters 10 and 20 as shown in FIG. As shown in the figure, cutting edges 11 and 21 having a substantially right-angled triangular cross section and a substantially trapezoidal front surface are provided at the tips of the cutters 10 and 20, and the sharp surfaces of the cutting edges 11 and 21 support the base material 2. When ascending and descending so as to be sheared, upper and lower protrusions 4 and 5 are simultaneously formed along the long side thereof together with the slit-shaped through hole 3. FIG.
In order to form the projections 4 and 5 as shown in (b), the cutting edges 11 and 2
2 are not opposed to each other as shown in FIG.
And 20 may be arranged.

The shape of the rug 1 can be arbitrarily selected. In addition to a circle, a square, and an ellipse as shown in FIG. 3, an irregular shape may be used. Further, the arrangement and distribution density of the through holes 3 are also arbitrary. 3 (a) and 3 (b) show an example in which upper and lower protrusions 4, 5 are formed along the long side of the slit-shaped through hole 3, and FIG. And the right square brackets indicate the slit-shaped through holes 3 having the downward projections 5.

The rug 1 need not be an integral sheet. For example, one or more windows may be provided only in a necessary portion of the rug 1, and a sheet provided with the through holes 3 and the projections 4 and 5 may be bonded to the window.

FIGS. 4 and 5 show an example of the container of the present invention. As shown in the drawing, the container 30 has a bottom wall 31 and a peripheral wall 32 rising from the peripheral edge thereof, and a flange 34 is provided on the outer periphery of the opening 33. The material of this container 30 is
As in the case of the rug 1, it may be a single or laminated body such as a metal foil such as aluminum, heat-resistant paper, a heat-resistant synthetic resin film or sheet.

The bottom wall 31 has a through hole 3a similar to the through hole 3 of the rug 1, and an upward projection 4a similar to the projections 4,5.
And a downward projection 5a. In the case of FIG. 4, the protrusions 4a and 5a are provided on the periphery of the through hole 3a.
As in FIG. 1B, only one protrusion 4a or 5a may be provided. The arrangement and distribution density of the through holes 3a can also be arbitrarily selected. Alternatively, one or more windows may be formed in the bottom wall 31, and a sheet having the through holes 3a and the protrusions 4a and 5a may be fixed to the windows.

The plane shape of the container 30 is arbitrary such as a circle, a polygon, and an ellipse. The flange 34 may or may not be provided.

[0016]

According to the present invention, as described above, a plurality of through-holes are provided in the bottom wall of a heating rug or a container, and one or both of an upward projection and a downward projection are provided around the periphery of the through-hole. Therefore, when a confectionery material or the like is placed and heated, a gap is formed between the confectionery material and the confectionery material, and at the same time, a gap is also generated between the confectionery material and the heating pan or the like. It is suitable for obtaining hard baking since moisture and the like easily escape.

Moreover, the through-holes and the upward and downward projections can be formed by cutting the sheet-like substrate with a cutter without the need for molding, so that there is no difficulty in manufacturing and the cost is advantageous. It is.
