Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an egg tray that is stacked and stored in an incubator or a refrigerated warehouse.
[0002]
[Prior art]
In general, when eggs such as chicken eggs are artificially hatched with an incubator, the fertilized eggs are stored in a predetermined egg tray and then stored together with the egg tray in the incubator. In order to effectively use many fertile eggs to hatch, multiple trays of eggs are stacked in the incubator. However, in this case as well, it is necessary for all the sperm eggs contained therein to enjoy good hatching conditions of a certain range of temperature, humidity and ventilation.
[0003]
Therefore, the conventional egg tray in the case of stacking a plurality of egg trays containing sperm eggs and storing them in an incubator has the following configuration. That is, in order to enjoy a good atmosphere (incubation conditions) of a certain range of temperature, humidity and ventilation to a sperm egg, in these egg trays, a support part for individually supporting each sperm egg to be accommodated The contact surface between the egg and the fertile egg is made small, and the lower part of the egg storage part of the egg tray is opened.
[0004]
In addition, even in a state where the egg trays are stacked in a plurality of stages, in order to make it possible to enjoy favorable hatching conditions for the sperm eggs of each stage, the eggs are formed so that an appropriate space is formed between the sperm eggs of each stage. The tray has a column (stacking leg). That is, a column portion (stacking leg) that protrudes upward on the upper surface side of the egg storage portion of the egg tray, and a column portion (stacking portion) that protrudes downward on the lower surface side of the egg storage portion of the egg tray. Legs) are formed. When stacking multiple egg trays, the column on the upper surface side of the egg storage part of the egg tray located immediately below is fitted to the column part on the lower surface side of the egg storage part of an egg tray, and integrated as a unit By forming a suitable space between both trays, all fertile eggs can be equally enjoyed with good hatching conditions such as a certain range of temperature, humidity and ventilation. Each egg tray includes a plurality of column portions on the upper surface side and a plurality of column portions on the lower surface side of the egg storage unit.
[0005]
In a conventional egg tray for an incubator, there is no column portion protruding downward on the lower surface side of the egg storage portion of the egg tray, and a receiving portion that simply receives the long protruding column portion of the egg tray located in the lower stage Some exist only. However, even in such an egg tray, there is a pillar portion that protrudes long upward on the upper surface side of the egg storage portion.
[0006]
[Problems to be solved by the invention]
Thus, if there is a column part that protrudes long upward on the upper surface side of the egg tray, it becomes an obstacle to accommodating the egg in the egg tray. In other words, the eggs are stored in the egg tray manually or by machine. In the case of manual operations, if there is a long protruding column on the upper surface of the egg tray, the egg to be stored is stored in the egg tray. It is necessary to work carefully so as not to hit the pillar, and as a result, it is difficult to perform the work quickly.
[0007]
In addition, even when the work is performed by a machine, if there is a pillar portion that protrudes upward on the upper surface side of the egg tray, it is necessary to consider the presence of the pillar portion in mechanization, which ultimately complicates the apparatus. As a result, the cost increases.
[0008]
The present invention enables a safe and quick storing operation when the above-described operation is performed manually when accommodating a fertilized egg in an egg tray. Moreover, even when the above operation is performed by a machine, the simple structure is inexpensive. An object of the present invention is to provide an egg tray that can be filled with an appropriate filling device.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the egg tray according to claim 1 is an egg for stacking and heating or cooling the eggs after stacking them in an orderly plane with their long axes held substantially vertically. The tray is provided with a rectangular storage portion in which a storage seat for storing eggs in an orderly manner is formed, and a pillar portion is provided at each corner of the four side edges of the rectangular storage portion, The lower part of the pillar part protrudes long on the lower surface side of the accommodating part, and the upper end of the pillar part is formed to be lower than the top of the egg when the egg is accommodated in the accommodating seat. When stacked, the lower end of the column part of the upper egg tray is configured to be fitted to the upper end of the column part of the lower egg tray, and the height of the uppermost part of each egg tray member is the egg accommodating state. And the egg tray containing the eggs is stacked in N stages. Wherein the total height is greater than the length of the long axis × N eggs.
[0010]
According to this structure, there is no thing like the pillar part protruded long on the upper surface side of the accommodating part. Therefore, when eggs are stored in an egg tray, safe and quick storage operations are possible when manually performed, and filling with an inexpensive filling device with a simple structure is possible even when the operations are performed by a machine. Become. Further, when a plurality of egg trays are stacked in a plurality of stages, an appropriate space is formed between the egg trays, so that the heating effect or the cooling effect can be enhanced. It is also possible to avoid the load on the upper egg tray from being applied to the lower egg.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The present invention is not limited to these examples.
[0014]
The egg tray A shown in FIGS. 1 to 3 is provided with an accommodating portion 1 formed of synthetic resin. On the upper surface of the housing portion 1, a plurality of approximate truncated cones 3 a are integrally raised in a state of being aligned at equal intervals. The height of the approximate truncated cone 3 a is formed so as to be lower than the top of the sperm egg E accommodated when the egg is accommodated in the accommodation seat 2. The accommodating seat 2 is formed so as to be surrounded by four approximate truncated cones 3a, and a predetermined number (5 × 6) of accommodating seats 2 are formed in an orderly arrangement in one accommodating portion 1. Yes. Each accommodating seat 2 is provided with a recessed portion 6 in order to stably hold the sperm egg E. And the bottom part of the recessed part 6 is opening.
[0015]
Each of the approximate truncated cones 3a is provided with an elliptical excision hole for holding the sperm egg E on the side surfaces facing each other. The upper surface of the approximate truncated cone 3a is opened.
[0016]
On the long side edge of the accommodating portion 1, five half-circular truncated cones 3b are raised as a unit. In addition, four half-conical truncated cones 3b that are also halved are integrally raised on the short side edge of the accommodating portion 1. On the four corners of the accommodating portion 1, a quarter-split approximate truncated cone 3 c is raised as a unit.
[0017]
Reference numeral 4 denotes a frame member, which is fixed to the four side edges of the accommodating portion 1.
[0018]
Reference numeral 5 denotes four column portions that are erected at each corner of the accommodating portion 1, and are fixed to the frame member 4. Even when the egg trays A are stacked in a plurality of stages, the column part 5 receives the load of the upper egg tray A, so that no burden is imposed on the sperm egg E. The height of the column portion 5 fixed to the frame member 4 is formed such that the upper end of the column portion 5 is lower than the top of the sperm egg E when the egg is accommodated in the accommodating seat 2. The height of the column part 5 on the upper surface side of the tray A, the approximate truncated cone 3a, etc. is approximately one-half to one-third of the major axis length of the sperm egg E accommodated in the accommodating seat 2. Preferably, it is formed lower than the top of the sperm egg E. Further, the column portion 5 protrudes long on the lower surface side of the housing portion 1. When a plurality of egg trays A are stacked, the lower end of the column part 5 of the upper egg tray A is formed so as to be fitted to the upper end of the column part 5 of the lower egg tray A.
[0019]
In the egg tray A configured as described above, the heights of the upper ends of the approximate truncated cone 3a, the half-shaped approximate truncated cone 3b, the quarter-divided approximate truncated cone 3c, and the column portion 5 are all contained in the storage seat 2. Is formed so as to be lower than the height of the top of the sperm egg when the sperm egg is accommodated in the egg tray A. Will not get in the way. Therefore, when the accommodating operation into the accommodating portion 1 is performed manually, a safe and quick accommodating operation is possible, and also when the operation is performed by a machine, filling with an inexpensive filling device having a simple structure is possible. Become.
[0020]
Even when the egg trays A are stacked in a plurality of stages, the upper stage load is received by the lower stage column part 5, so that no burden is imposed on the eggs stored in the lower stage egg tray A. Moreover, since the lower end of the column part 5 of the upper egg tray A is formed so as to be fitted to the upper end of the column part 5 of the lower egg tray A, the egg tray A can be stably stacked. Furthermore, since an appropriate space is formed between the egg trays A at each stage due to the presence of the column portion 5, the hatching conditions sufficient for all the sperm eggs E accommodated in the egg tray A at each stage are enjoyed. The hatching rate can be improved.
[0021]
In addition, unlike the said Example, you may provide the column part 5 in the corner inner side or its vicinity instead of providing in each corner | corner of the accommodating part 1. FIG. Moreover, the accommodating part 1, the frame material 4, and the pillar part 5 may be shape | molded integrally, and the accommodating part 1 and the frame material 4 are good also as attachment or detachment.
[0022]
So far, as an example of use of the egg tray A, the case of artificially hatching a fertilized egg with an incubator has been described, but as another example, edible eggs are accommodated in the egg tray A and stored in a refrigerator. There is a case. Today, refrigerated storage of edible eggs in the distribution stage is gradually spreading as consumers become more concerned about food hygiene, but many egg trays A containing edible eggs are stacked in a refrigerated warehouse. When stored, all the edible eggs stored can be sufficiently chilled by an appropriate space formed between the stacked egg trays A. Thereby, a sufficient cooling effect can be achieved while being stored at a high density. Also in the case of this usage example, there is no obstacle such as a pillar protruding long in the upper direction on the upper surface side of the accommodating portion 1 of the egg tray A. Therefore, the edible egg is accommodated in the egg accommodating portion 1. Can be done easily. Therefore, when this operation is performed manually, a safe and quick accommodation operation is possible, and even when the operation is performed by a machine, filling with an inexpensive filling device having a simple structure is possible. Further, the presence of the fitting portion enables stable stacking.
