Description

Container assembly material

The present invention relates to a container assembly material used as a baking mold (especially Celcle) when baking foods produced by baking dough, such as bread and baked confectionery.

Some breads and confectionery are manufactured by placing the dough in a baking mold of a predetermined shape and, if necessary, passing through a fermentation process in that state and then baking it. Conventionally, such baking molds have been mainly made of a metal such as aluminum, but recently, those made of a heat-resistant silicone resin or other heat-resistant resins have also been disclosed (patents). Reference 1).
In addition, among the baking molds, there is a paper-made one called “Celcle” that has only the outer frame and has no bottom (see Patent Document 2). These paper selcles are made of a long cylinder by wrapping a paper material such as cardboard around a metal bar, and after this is cut into an appropriate length, the surface is coated with silicone resin. Is formed. This cellul is placed on a top plate, and the dough is put inside and fired, and the mold is removed after the firing is completed.

Note that Patent Document 3 discloses that a cylindrical baking mold is formed by connecting both ends of a rectangular coated paper. Patent Document 4 discloses disposing a heat-resistant resin material on a sheet used for a baking mold for bread or pie. Further, Patent Document 5 discloses that a baking paper tray for bread and confectionery is formed of laminated paper laminated with a synthetic resin, and further a silicone film is formed on the inner surface thereof.

JP 2004-242591 A JP 2007-228886 A Registered Utility Model No. 3013085 JP 2001-204367 A Registered Utility Model No. 3140826

However, although the baking mold described in Patent Document 1 and the paper celkle described in Patent Document 2 are less expensive than metal products, they are bulky and are therefore inefficient when transported in large quantities and have a wide storage area. There was a problem of requiring space.
On the other hand, it is difficult to maintain a desired shape when trying to form a cylindrical shape having a straight part in all or part of a rectangular paper as described in Patent Document 3, such as a rectangular bottom surface. There is something to do.
In addition, when baking a plurality of breads, confectionery, etc. in a baking tray using the above-mentioned Celcle, it is necessary to leave an appropriate space between the individual Celcles in order to maintain a uniform baking temperature. There is. To that end, it is necessary to place the celkles in a firing tray shape with the operator consciously spaced from each other, but sometimes they may come into contact with each other, causing uneven burning. .

Therefore, in view of the above problems, the present invention is excellent in heat resistance and durability, has high transport efficiency, saves storage space, can easily maintain a desired shape, and is moderate. It is an object of the present invention to provide a container assembly material for forming a baking container that can easily secure an interval between containers.

In order to solve the above problems, the present invention is a container assembly material for forming a baking container used for baking production of food by bending or bending a thin plate substrate formed of a paper material, the thin plate base A heat-resistant release layer as a covering layer covering at least one side of the material, a substantially rectangular side surface forming portion surrounded by two long sides and two short sides, and both-end engagement provided near each short side Portion and each long side bent or curved to engage the both end engaging portions to form a hollow cylindrical firing container having both bottom surfaces open, from the opposite position of each long side to the opposite direction And a plurality of sets of reinforcing portions protruding to each other, wherein the reinforcing portions of each set can be engaged with each other in a state of being bent outward of the hollow cylindrical shape.

Here, the “baking container” is a container used as a baking mold when baking foods such as baked confectionery such as bread and cakes, cookies, etc., and in particular, a cylindrical container composed only of a frame. Say. If necessary, the fermentation process of the dough before baking can also be performed therein.
The “container assembly material” is a thin plate-like member that forms the firing container and is formed on the basis of a thin plate base material formed of paper. The thin plate base material using this paper material is preferably subjected to a dehumidification treatment before the coating layer is coated.
The “heat-resistant release layer” is a layer that covers at least one surface of a thin plate base material, and has heat resistance and release properties in order to improve the release property of food formed by baking in a baking container. Is a layer. As the heat-resistant release layer, for example, a silicone resin layer coated with a silicone resin can be used. The silicone resin layer is preferably a reaction-curing type which is rich in non-adhesiveness and excellent in heat resistance and has no problem in terms of food hygiene. The heat-resistant release layer only needs to cover at least one surface of the thin plate base material, and may cover both surfaces of the thin plate base material. At least, when the container assembly material is made into a baking container, the inner surface that comes into contact with food needs to be covered with a heat-resistant release layer.

In the present invention, the heat-resistant resin formed of a heat-resistant resin such as crystalline polyethylene terephthalate (C-PET) or polybutylene terephthalate (PBT) as a coating layer under the heat-resistant release layer. Additional layers can be provided. In other words, it is possible to coat the paper material with a heat-resistant resin layer made of C-PET or PBT, and further coat a heat-resistant release layer, preferably a silicone resin layer, as an upper layer. By providing such a heat-resistant resin layer, the heat resistance of the container assembly material is increased, and a restoring force is applied to the paper material, so that the engagement force between the two end engaging portions of the container assembly material formed in a cylindrical shape is increased. Strengthened. This strengthening of the engaging force is more effectively exhibited by providing the heat resistant resin layers on both surfaces of the thin plate base material.

The “long side” of the thin plate substrate is the side that is bent or bent when the container assembly material is bent or bent, and the “short side” is the long side that is bent or bent. By doing so, they are sides that can be combined with each other.
A substantially rectangular portion surrounded by the long side and the short side is a “side surface forming portion”, which is a portion that forms the side surface of a cylindrical baking container formed by bending or bending the long side.
The “both end engaging portions” are provided in the vicinity of the two short sides. This both-ends engaging part may be provided in the short side, and may be provided in the vicinity of the short side in a long side. Further, the shape of the engagement portions on both ends may be any shape as long as they can be engaged with each other and can be coupled by overlapping the short sides. For example, a notch as a both-end engaging portion is provided near one end on one long side, and a notch as a both-end engaging portion is provided near the other end on the other long side. The side surface forming portion can be formed in a cylindrical shape by engaging the notches with each other. Here, the side surface forming portion being “substantially rectangular” is not necessarily an exact rectangular shape, for example, it is a rounded corner, or the both end engaging portions are protruded or notched. It is meant to include those that are.

In addition, the “reinforcing portion” protrudes in the opposite direction from the position where each long side opposes in a state where the long side is bent or curved and the both end engaging portions are engaged to form the side surface forming portion in a cylindrical shape. It is a part formed. A plurality of sets of the reinforcing portions are provided, with two sets facing each other across two long sides. The reinforcing portions of each set have shapes that engage with each other in a state of being bent outward. Although there is no particular limitation on this shape, for example, an engagement hole is provided in one of the reinforcing portions of each set, and an engagement piece is provided in the other, and the engagement piece is inserted into the engagement hole. Thus, it is desirable that the reinforcing portions of each set can be engaged with each other. This engagement hole may be formed in a slit shape.

Furthermore, the engagement hole is formed in a trapezoid shape that decreases in width as it is away from the long side of the side surface forming portion, and the engagement piece is a trapezoidal shape that increases in width as it is away from the long side of the side surface forming portion. Of the reinforcing portions of each set, the side having the engagement piece is bent outward from the side surface, and the side having the engagement hole is also bent outward from the side surface in the same manner. It is also possible to form the engagement hole and the engagement piece so as to substantially coincide with each other. Here, “substantially coincide” means that the engagement pieces coincide with each other so that the engagement pieces can be passed through the engagement holes. If formed in this way, among the reinforcing portions of each set, the one having the engagement piece is bent outward from the side surface, and the one having the engagement hole is similarly bent outward and overlapped. , The narrow proximal portion of the engagement piece fits into the narrow distal portion of the engagement hole due to the restoring force of the paper. As a result, the reinforcing portions are engaged with each other and are not separated naturally. For this reason, a desired cylindrical shape can be maintained. Further, the presence of this reinforcing portion prevents adjacent firing containers from contacting each other's side surfaces.
In addition, the width of the engagement piece is formed wider than the width of the engagement hole, and a portion of the width of the engagement piece that protrudes from the width of the engagement hole is from the engagement hole. It may be formed as a retaining portion.

Moreover, if the reinforcement part is provided over the full length of each long side, the completed baking container will make a cylindrical shape of a bottom shape polygon. Further, assuming that a reinforcing portion is provided on a part of each long side, a portion where the reinforcing portion is provided on the bottom surface forms a straight line, and a portion where the reinforcing portion is not provided has a curved shape. Become.
In addition, it is desirable that one set of the plurality of sets of reinforcing portions is provided at a position including a portion where both end engaging portions are engaged. By doing so, it is possible to prevent the reinforcing portion from being disengaged by the both end engaging portions.
In the container assembly material according to the present invention, the side surface forming portion is bent or bent so that the surface on which the heat-resistant release layer is provided is on the inside, and the both end engaging portions at both ends are engaged with each other. A cylindrical firing container can be formed. In this state, the opposing reinforcing portions provided on the long sides are bent outward and engaged with each other, whereby the bottom shape of the baking container is held without being flattened. And, for example, this baking container is placed on a top plate, and dough such as bread or confectionery is poured into the cylindrical internal space, and after treatment such as fermentation as necessary, it is put in an oven or the like. It will be used for firing. After baking, since the heat-resistant release layer is provided on the inner surface of the baking container, bread, confectionery, etc. can be easily taken out from the baking container.

Since the container assembly material according to the present invention is configured as described above, the following effects can be obtained. In other words, because it has a heat-resistant release layer, it has excellent heat resistance and durability, and it has a thin plate shape before being assembled into a baking container, so it has high conveyance efficiency and can be easily decomposed into a thin plate shape after use. Therefore, the storage space before and after use can be saved. Furthermore, by providing the reinforcing portion, it is possible to form a fired container that can easily maintain a desired shape and can easily secure an appropriate interval between containers.

Embodiments of the present invention will be described below with reference to the drawings.
(1) 1st Embodiment FIG. 1: shows the container assembly raw material 10 which concerns on 1st Embodiment with an expanded view. The container assembly material 10 is a thin plate-like member for forming the firing container 1. Specifically, the container assembly material 10 includes a rectangular side surface forming portion 23 surrounded by two long sides 21 facing each other and two short sides 22 facing each other, and in an opposite direction from each long side 21. It comprises a plurality of sets (four sets in FIG. 1) of reinforcing portions 26 provided so as to protrude. Further, in the vicinity of the end portion of each long side 21, a part thereof is cut out so as to reduce the width in the short side 22 direction, and a both-end engaging portion 24 as a wedge-shaped cutout is further formed. The reinforcing portions 26 are arranged without gaps along the long side 21 except for portions where the both-end engaging portions 24 are provided.

A trapezoidal engagement hole 27 is provided at a position where the bottom side is in contact with the long side 21 on the one side of each reinforcing portion 26. In the engagement hole 27, the length of the base 27a on the proximal side with respect to the long side 21 is longer than the length of the base 27b on the distal side. In addition, an engagement piece 28 that protrudes in a trapezoidal shape is provided on the other side of each reinforcing portion 26. In this engagement piece 28, the length of the base side 28a on the proximal side with respect to the long side 21 is shorter than the length of the base side 28b on the distal side. The base 27a on the proximal side of the engagement hole 27 and the base 28b on the distal side of the engagement piece 28 have substantially the same length. The bottom side 27b on the distal side of the engagement hole 27 and the bottom side 28a on the proximal side of the engagement piece have substantially the same length. Furthermore, the height of the trapezoid that forms the engagement hole 27 and the height of the trapezoid that forms the engagement piece 28 are approximately the same length. That is, the engagement piece 28 is substantially the same size as the engagement hole 27 to the extent that it can pass through the engagement hole 27.

Next, the material configuration of the container assembly material 10 will be described.
An enlarged cross-sectional view of the container assembly material 10 is shown in FIG. As shown in FIG. 2A, the container assembly material 10 is obtained by coating both surfaces of the thin plate base material 20 with a coating layer. That is, the both sides of the paper material as the thin plate substrate 20 are coated with the heat-resistant resin layer 40, and the silicone resin as the heat-resistant release layer 30 with the low-temperature curing silicone resin so as to cover the upper layer of the heat-resistant resin layer 40 Layer 30 is coated.
Here, as the thin plate substrate 20, paper having a weight of 200 to 450 g / m ² , preferably 250 to 350 g / m ² is used. The thickness of the thin plate substrate 20 is 0.3 to 1.0 mm, preferably 0.4 to 0.7 mm. Further, since it is used for food, the thin plate base material 20 is preferably made of virgin pulp. Since the thin plate substrate 20 contains water of several weight percent, usually about 7 weight percent, it is preferable to perform a dehumidification treatment before coating with the heat resistant resin layer 40.

As the heat resistant resin layer 40, crystalline polyethylene terephthalate (C-PET) or polybutylene terephthalate (PBT) is used. When C-PET or PBT is used as the heat-resistant resin layer 40, a stronger restoring force can be imparted to the thin plate base material 20 made of paper, and the thin plate base material 20 bent or curved into a cylindrical shape can be provided. By the restoring force, the engaging force between the two end engaging portions 24 and the engaging force between the reinforcing portions 26 are strengthened.
The material of the silicone resin layer 30 is preferably a room temperature curable (RTV) silicone resin. As the room temperature curable silicone resin, for example, a one-component RTV rubber KE45 (Shin-Etsu Chemical Co., Ltd.) commercially available can be used. This silicone resin is obtained by blending silica with a polymer formed by siloxane bonds. This is diluted with a solvent such as toluene so that the resin content is 5 to 20% by weight, and is applied by spraying or the like. If this is left overnight at room temperature, the resin hardens and the silicone resin layer 30 is formed.

In addition, it is good also as using an addition reaction type thermosetting silicone resin instead of said room temperature curing type silicone resin. As such a resin, for example, those commercially available under the trade name KS-774 (Shin-Etsu Chemical Co., Ltd.) can be used. Such a thermosetting silicone resin is diluted as it is or appropriately so as to have a viscosity that is easy to use in a solvent such as toluene, and a metal salt such as platinum is added as a curing catalyst and stirred well, and the inner surface of the baking container Apply by spraying. Next, the silicone resin layer 30 can be similarly formed by subjecting it to a curing treatment of heating at around 150 ° C. to cure the thermosetting silicone resin.

As shown in FIG. 2B, the container assembly material 10 may have a configuration in which both surfaces of the thin plate base material 20 are coated only with the silicone resin layer 30 as the heat-resistant release layer 30.
Although not particularly shown, the silicone resin layer 30 may be coated only on one side of the thin plate base material 20. In this case, when the baking container 1 is formed of the container assembly material 10, the silicone resin layer 30 is arranged on the cylinder inner surface side (surface that comes into contact with food).
Next, the assembly from the container assembly material 10 to the firing container 1 will be described with reference to FIGS.
The side surface forming portion 23 is folded while being mountain-folded along a fold line 25 (see FIG. 1) parallel to the short side 22 (FIG. 3). Then, both side engaging portions 24 are engaged (FIG. 3) and engaged (FIG. 4) so that the side surface forming portion 23 is slightly twisted. At the same time, the reinforcing portions 26 are also folded along the long side 21 (FIG. 3) and bent outward (FIG. 4). Here, one set of the reinforcing portions 26 faces each other so as to sandwich the position where the both end engaging portions 24 engage with each other (FIG. 4).

First, the reinforcing part 26 having the engaging piece 28 is folded, and the reinforcing part 26 having the engaging hole 27 is folded so as to cover the reinforcing part 26 (FIG. 5). At this time, the engagement piece 28 and the engagement hole 27 substantially coincide with each other. When the finger is released from the reinforced portion 26 folded from this state, the reinforced portion 26 expands outward by the restoring force of the thin plate base material 20 as shown in FIG. At this time, the engagement piece 28 passes through the engagement hole 27, and the bottom side 28a portion on the proximal side of the engagement piece 28 is the bottom side 27b portion on the distal side of the engagement hole 27 having substantially the same length (see FIG. 4). ) And the reinforcing portions 26 are engaged with each other (FIG. 6). In this state, the engagement piece 28 does not come out of the engagement hole 27 unless an external force is applied. Since the engagement relationship between the engagement hole 27 and the engagement piece 28 is equally balanced in each of the four side surfaces, as a result, the shape of the baking container 1 can be held without applying any external force. It has become. In particular, the reinforcing portion 26 where the both-end engaging portions 24 are engaged contributes to maintaining the engagement.

The baking container 1 formed as described above is placed on the top plate, and bread or confectionery dough is placed inside the cylinder, and subjected to a fermentation process if necessary, and then baked in a conveyor oven. Manufacture bread and confectionery. At this time, as described above, since the silicone resin layer 30 is formed on the inner surface of the cylinder, the baked food can be easily released. Further, since the releasability is increased by the silicone resin layer 30, it is not necessary to apply a release oil, so that the heat resistant resin layer 40 of the baking container 1 does not deteriorate and can withstand repeated use. It has become.
As described above, according to the present embodiment, since the firing container 1 is formed by assembling the thin plate-shaped container assembly material 10, it is not bulky during transportation and stored as compared with the three-dimensional firing container 1. No space for time. Further, both end portions of the container assembly material 10 are coupled by engagement between both end engaging portions 24 provided on each side, and the shape is maintained by engagement of a plurality of sets of reinforcing portions 26. Therefore, assembly and disassembly operations are relatively easy and suitable for recycling.

In addition, since the thin plate substrate 20 is coated with the silicone resin layer 30, it has excellent releasability, and the heat resistance can be enhanced by coating the thin plate substrate 20 with C-PET or PBT as the heat resistant resin layer 40. it can. Furthermore, by using C-PET or PBT as the heat-resistant resin layer 40, the restoring force of the container assembly material 10 is increased, and when the container assembly material 10 is formed into a cylindrical shape, both ends engage with a force to return to the original shape. The engagement between the portions 24 is strengthened, and the engagement between the reinforcing portions 26 is also strengthened, so that the deformation of the shape can be prevented.
In addition, as shown in FIG. 6, the reinforcing portion 26 protrudes outward from the side surface of the cylindrical shape. Therefore, when a plurality of firing containers 1 are arranged on the top plate, the reinforcing portion 26 Appropriate spacing between the side surfaces can be secured between the protruding portions. As a result, the baking containers 1 do not come into contact with each other, and heat can pass evenly through the dough inside to prevent baking unevenness.

(2) Second Embodiment A container assembly material 10 according to a second embodiment of the present invention is provided with three sets of reinforcing portions 26 along the long side 21 as shown in FIG. It has been. The reinforcing portions 26 are separated by a gap.
In the present embodiment, it is assembled in the same manner as in the first embodiment. However, as shown in FIG. 7 (B), the portion where the reinforcing portion 26 is not provided is an arc shape that is approximately one third. Are formed so as to form an equilateral triangular bottom shape with the apex portion rounded in plan view.

(3) Third Embodiment As shown in FIG. 8A, the container assembly material 10 according to the third embodiment of the present invention is provided with two sets of reinforcing portions 26 along the long side 21. It has been. The reinforcing portions 26 are separated by a gap.
In the present embodiment, it is assembled in the same manner as in the first embodiment, but the portion where the reinforcing portion 26 is not provided is curved so as to form a substantially semicircular round as shown in FIG. In plan view, however, it has an oval bottom shape.
(4) Others In each of the above embodiments, the engagement hole 27 and the engagement piece 28 provided in the set of reinforcing portions 26 have substantially the same shape, but as in the modification shown in FIG. The width of the engagement piece 28 can also be formed larger than the width of the engagement hole 27. In this case, a portion of the engagement piece 28 that protrudes from the width of the engagement hole 27 (a retaining portion 29) is folded in advance, and then folded as shown in FIG. 5, and the reinforcing portion 26 is moved as shown in FIG. In the restored state, it is possible to prevent the engagement piece 28 from being detached from the engagement hole 27 by expanding the bent retaining portion 29 that has been bent.

The present invention can be used as a baking container for bread and baked goods.
