JP-A-11-255282 (page 2-4, FIG. 5)

  FIG. 4 is a plan view for explaining an embodiment of an egg container T described in Patent Document 1. As shown in FIG. As shown in FIG. 4, the egg storage container T (hereinafter referred to as the storage container T) is formed, for example, by injection molding synthetic resin, and is formed in a rectangular shape in plan view.

  At the corners of the four corners of the storage container substrate 1 in the storage container T, projections 2 each having a substantially right triangular pyramid shape protruding above the storage container substrate T are formed. Further, five semi-conical truncated projections 3 projecting upward from the storage container substrate 1 are formed at a pitch of, for example, about 55 mm on the edge on the long side except for the four corners of the storage container substrate 1. Similarly, four semi-conical frusto-conical projections 3 are formed at a pitch of about 55 mm on the short side edge of the container substrate 1.

  Furthermore, 20 (5 × 4) frustoconical protrusions 4 are formed on the upper surface of the container case 1 except for the corners of the four corners and the edges of the sides of the container case 1. The projections 3 are aligned in the same pitch as that of the projections 3. The storage container substrate 1 includes the frustoconical protrusion 4, the frustoconical protrusion 4 and the semicircular truncated protrusion 3, and the frustoconical protrusion 4 and the semiconical truncated protrusion 3. Egg projection recesses 5 formed so as to surround the four sides by the projections of the substantially right-angled triangular pyramid-shaped projections 2 are configured in 6 columns and 5 rows.

  In addition, the heights of the tops of the frustoconical protrusions 4, the semi-conical frustoconical protrusions 3, and the substantially right triangular pyramidal protrusions 2 are the same as those of the egg E in a state where the egg E is accommodated in the egg accommodating recess 5. It is formed lower than the top. In addition, a substantially elliptical cutout hole 6 is formed in the peripheral wall portion of each of the protrusions 4, 3, 2 for facilitating holding the side peripheral portion of the egg E accommodated in the egg accommodating recess 5. .

  As shown in the figure, the engagement protrusions 7 are fixed to the tops of the first, third and fifth frustoconical protrusions 4 in the first and fourth rows.

  With the above-described configuration, each of the storage containers T is stacked by rotating the orientation direction of each storage container T by 90 degrees so that the long and short sides of the storage container T do not overlap each other. An egg accommodating space is formed between the containers T, and a large amount of eggs E can be handled.

  When the storage container T is not used, the orientation direction of the storage container T is set to the same direction, and the protrusions 4, 3, 2 of the lower storage container T are the protrusions 4, 3, 2 of the upper storage container T. Stack so that it fits on the back of the. Thereby, it can be set as the state which each upper and lower container T closely_contact | adhered, and the bulkiness by stacking can be eliminated.

  By the way, the stacking operation of the empty storage containers T is performed by, for example, mechanical means or human means, and is stacked upward in order from the used storage containers T to form a stack of empty storage containers T. Will be.

  However, as shown in FIG. 5, in the process of newly stacking empty storage containers T on a stack of empty storage containers T that have already been stacked, the empty storage containers T lose their horizontal posture. (In essence, the balance is lost) and the projection 2f having a substantially right triangular pyramid shape in the lower storage container Tf collides with a part of the empty storage container T main body to be newly stacked, Deviation occurs in the laminated state.

  As a result, the substantially right triangular pyramidal projection 2f in the lower storage container Tf does not fit well on the back side of the one substantially right triangular pyramidal projection 2g in the upper storage container Tg, so There is often a phenomenon that the conical protrusion 2f protrudes to the outside.

  Without repeating the above phenomenon, when repeating the stacking of a large number of empty storage containers T on the storage container Tf, the storage container Tf has a substantially right triangular pyramidal projection 2f protruding outward. It will not be restored. Furthermore, in combination with the fact that the substantially right triangular pyramidal projection 2 has a lower strength than the other projections (the truncated cone-shaped projection 4 and the semi-conical truncated projection 3), in the worst case, the root of the projection 2f. There was a problem of breaking.

  Moreover, when the stacked body of the storage container T including the storage container Tf in which the above-described problem has occurred is set in a storage container supply device such as a sorting device, the storage container supply device stores the stack from the storage container T one by one. When the container T was peeled and supplied, there was a problem that a peeling error occurred.

  Accordingly, the present invention has been made to solve the above-mentioned problems, and the object of the present invention is to prevent deformation and breakage of the storage containers during stacking, and ensure that the upper and lower storage containers are securely connected. An object of the present invention is to provide an egg storage container that can be stacked in close contact with each other.

In the invention of the egg container according to claim 1, the egg container recess for accommodating the long axis of the egg in a substantially vertical manner in N columns and M rows (N ≠ M) is formed in a rectangular container container, Around each egg receiving recess, a plurality of protrusions protruding above the receiving container substrate are formed to support the eggs stored in the egg receiving recess, and the plurality of protrusions are corners of the four corners of the receiving container substrate. Are provided at the positions of the half-conical substantially frustum-shaped projections formed at the long side edge and the short side edge, the projections provided at the corners of the four corners, and other storage container substrates. In the egg storage container formed with a substantially frustum-shaped protrusion, the height of the top of each protrusion is lower than the top of the egg in a state in which the egg is stored in the egg receiving recess, at the corners of the four corners The top of the protrusion to be provided is either a substantially frustum-shaped protrusion or a half-shaped substantially frustum-shaped protrusion. Lower than, the long and short sides imaginary outer line connecting the outer edge of each projection having a substantially frustum-shaped halved portion formed on the edge of each side of constituting a corner of the container substrate It is characterized in that it is formed closer to the egg accommodating recess in plan view than the intersection .

In the invention of the egg container according to claim 2, in the invention of claim 1, ribs that connect the tip portions of the egg accommodating recesses to each other are formed in a lattice shape at the bottom of the container substrate. It is characterized by being .

In the invention of the egg container according to claim 3 , in the invention of claim 1 or 2 , the outer side of the projections at the corners of the four corners is subjected to R processing. Is.

As is apparent from the above description, according to the first invention, in particular, the tops of the protrusions provided at the corners of the four corners of the storage container substrate are substantially frustum-shaped protrusions and half-divided substantially frustum shapes. The outer edge of each half-shaped substantially truncated cone-shaped projection which is lower than any one of the tops of the projections and is formed at the edge of each of the long and short sides constituting the corner of the container substrate It is set as the structure formed near the egg accommodation recessed part by planar view rather than the intersection of the virtual outer edge line which tied No ..

  Therefore, when a new empty storage container is stacked on a stack of empty storage containers that have already been stacked, the empty storage container temporarily loses its horizontal position (in essence, loses balance) Even when stacked on the laminated body, as a result of avoiding collision between one protrusion at the corners of the four corners of the lower container and a part of the empty container body to be newly stacked, The container can be correctly stacked while preventing the occurrence of displacement. Thereby, there exists an effect that the deformation | transformation and damage of the storage container at the time of the stacking | stacking which were the subjects of the prior art can be eliminated.

Furthermore, according to the second invention, in a first shot Ming configuration, the bottom of the container substrate has a rib for connecting the tip of each egg receiving recess with each other to form a grid.

According to the third invention, in the configuration of the first invention or the second invention , the outer side of the projections at the corners of the four corners is subjected to R processing.

  Therefore, when stacking empty storage containers, there is no catch on the fitting portion between one projection at the corners of the four corners of the lower storage container and the back side of one projection at the four corners of the storage container. The upper and lower storage containers can be stacked in a state where they are in close contact. In addition, even when a stack of empty storage containers is set in a storage container supply device such as a sorting device, the above-mentioned mating parts are not caught, so the stack of empty storage containers is securely stored one by one. It becomes easy to peel the container, and it becomes possible to reduce the peeling error of the storage container in the storage container supply device.

  Next, as an embodiment of the present invention, an egg container will be described with reference to the accompanying drawings.

  FIG. 1 is a plan view of an egg container T according to an embodiment of the present invention, FIG. 2 is a side view of the egg container T, and FIG. FIG. 3B is a partial detailed view illustrating another modified example of the egg container T. FIG. In addition, the part shown with the same code | symbol as the container T of the prior art in the drawing has shown the same component.

  An egg storage container T (hereinafter referred to as a storage container T) according to the present invention is formed, for example, by injection molding a synthetic resin such as polyethylene containing an antibacterial agent as shown in FIG. As shown, it is formed in a rectangular shape in plan view.

  At the corners of the four corners of the storage container substrate 1 in the storage container T, protrusions 20 having a substantially right triangular pyramid shape projecting upward from the storage container substrate 1 are formed. Further, five semi-conical trapezoidal protrusions 3 projecting upward from the storage container substrate 1 are formed, for example, at a pitch of 55 mm on the edge of the storage container substrate 1 excluding the four corners. Similarly, four semi-conical protrusions 3 are formed at a 55 mm pitch at the edge on the short side.

  Furthermore, 20 (5 × 4) frustoconical protrusions 4 are formed on the upper surface of the container case 1 except for the corners of the four corners and the edges of the sides of the container case 1. The projections 3 are aligned in the same pitch as that of the projections 3.

  Therefore, the storage container substrate 1 includes the frustoconical protrusion 4, the frustoconical protrusion 4 and the semiconical frustoconical protrusion 3, and the frustoconical protrusion 4 and the semiconical frustoconical protrusion 3. The egg receiving recesses 5 formed so as to surround the four sides by the protrusions of the substantially right triangular pyramid-shaped protrusions 20 are configured in 6 columns and 5 rows, and the egg receiving recesses 5 are formed at a pitch of 55 mm. .

  Note that the distance between both edge portions of the container container 1 and the center of the egg storage recess 5 adjacent thereto is ½ of the pitch between the egg storage recesses 5, that is, 27.5 mm. Thereby, when the storage container T is continuously arranged, the interval between the eggs E positioned at the boundary of the storage container T can be made equal to the pitch between the egg storage recesses 5 (55 mm).

  The heights of the tops of the frustoconical protrusions 4, the semiconical frustoconical protrusions 3, and the substantially right triangular pyramidal protrusions 20 are higher than the tops of the eggs E when the eggs E are accommodated in the egg accommodating recesses 5. Is also formed low.

  As illustrated, an elliptical cutout hole 60 is formed in the peripheral wall portion of each of the protrusions 4, 3, 20. Thereby, while it becomes easy to hold | maintain the side peripheral part of the egg E accommodated in the egg accommodation recessed part 5, it can be freely made to come and go of atmosphere, such as a cooling medium, for example.

  As shown in FIG. 2, reinforcing ribs 30 that connect the tip portions of the egg storage recesses 5 to each other are formed in a lattice shape at the bottom of the storage container substrate 1. Thereby, when 30 eggs E are accommodated in the egg accommodating recess 5, it is possible to prevent the accommodating container T body from being bent by its weight.

  As shown in FIG. 1, the tops of the first, third, and fifth rows of the frustoconical protrusions 4 in the first and fourth rows are, for example, approximately 10 mm in diameter at the bottom and 8 mm in height. A frustoconical engagement protrusion 70 is formed. Thereby, when the orientation direction of each container T containing the egg E is rotated by 90 degrees and stacked in a plurality of stages, each container T stacked by the action of the engaging projection 70 is subjected to a force from the lateral direction. In contrast, it is possible to reliably prevent the displacement.

  Next, a characteristic configuration of the egg container T according to the present invention will be described. As shown in FIG. 2, when attention is paid to the substantially right triangular pyramid-shaped protrusions 20 formed at the corners of the four corners of the storage container substrate 1, the tops of the respective substantially right triangular pyramid-shaped protrusions 20 are adjacent to each other. The top of the truncated cone-shaped projection 4 or the top of the semi-conical-shaped projection 3 is formed to be about 3 mm to 4 mm lower.

  With the above-described configuration, the egg storage container T according to the present invention is tentatively provided when an empty storage container T is newly stacked on a stack of empty storage containers T that have already been stacked. Even if T collapses in a horizontal posture (in other words, loses balance) and is stacked on the laminate, one substantially right triangular pyramid-shaped protrusion 20 at the corners of the four corners of the lower container T As a result of avoiding a collision with a part of the empty container main body to be stacked, the container T can be correctly stacked while preventing the occurrence of deviation in the stacking process.

  Accordingly, it is possible to eliminate the phenomenon that one of the right-angled triangular pyramidal protrusions 20 of the storage container T protrudes to the outside, which is a problem of the prior art.

  As described in the present embodiment, the tops of the substantially right triangular pyramidal projections 20 formed at the corners of the four corners of the storage container substrate 1 are the tops of the adjacent truncated cone-shaped projections 4 at four locations. Alternatively, it is the most preferable form that the height is about 3 mm to 4 mm lower than the top of the semi-conical protrusion 3, but the present invention is not limited to this. For example, the tops of the three substantially right triangular pyramidal protrusions 20 are adjacent to each other. The top of the truncated cone-shaped projection 4 or the top of the semi-conical-shaped projection 3 may be formed to be about 3 mm to 4 mm lower, or, for example, two substantially right triangular pyramidal projections on the diagonal line Only the top of 20 may be formed to be lower by 3 mm to 4 mm than the top of the adjacent frustoconical protrusion 4 or the top of the semiconical protrusion 3.

  In the present embodiment, the protrusions formed at the corners of the four corners of the container substrate 1 have been described as the protrusions 20 having a substantially right triangular pyramid shape. May be. Further, the frustoconical protrusion 4 and the semi-conical frusto-shaped protrusion 3 may also be a truncated pyramid-shaped protrusion and a semi-pyramidal truncated protrusion instead.

  Fig.3 (a) is a partial detail drawing explaining the modification of the egg storage container T concerning this invention. As shown in FIG. 3 (a), the top portions 20 b of the substantially right triangular pyramidal projections 20 formed at the corners of the four corners of the storage container substrate 1 are the long sides constituting the corners of the storage container substrate 1. For example, about 3 mm to 5 mm closer to the egg accommodating recess 5 in a plan view than the intersection of the virtual outer edge lines connecting the outer edges of the semi-conical truncated projections 3 formed on the side edge and the short side edge. It is preferable to be formed.

  In this way, when stacking empty storage containers T, one substantially right triangular pyramidal projection 20 at the corners of the four corners of the lower storage container and one approximately at the corners of the four corners of the upper storage container. An appropriate gap is generated at the fitting portion between the right side triangular pyramid-shaped protrusion 20 and the back side. As a result, even when a stack of empty storage containers T is set in a storage container supply device such as a sorting device, an appropriate gap is formed in the above-described fitting portion. The container T can be easily peeled from the body one by one reliably, and it becomes possible to reduce the peeling error of the container T in the container supply apparatus.

  As described in the present modification, the top portions 20b of the substantially right triangular pyramid-shaped projections 20 formed at the corners of the four corners of the storage container substrate 1 are the long sides constituting the corners of the storage container substrate 1. From the intersection of the virtual outer edge lines connecting the outer edges of the semi-conical frusto-shaped projections 3 formed on the edge of each of the short sides and the edge of the short side, for example, about 3 mm to 5 mm closer to the egg containing recess 5 Although it is the most preferable form that it is formed, it is not limited to this, for example, the apex portion 20b of the three substantially right triangular pyramidal projections 20 may be formed closer to the egg accommodating recess 5, For example, only the apexes 20 b of the two substantially right triangular pyramidal projections 20 on the diagonal line may be formed closer to the egg accommodating recess 5.

  FIG. 3B is a partial detail view for explaining another modified example of the egg container T according to the present invention. As shown in FIG. 3B, the outer surface 20a of the substantially right triangular pyramidal projection 20 formed at the corners of the four corners of the storage container substrate 1 is subjected to R processing (curved surface processing). Preferably it is.

  In this way, when stacking the empty storage containers T, one substantially right triangular pyramidal projection 20 at the corners of the four corners of the lower storage container and the four corners of the upper storage container to be newly stacked. Since the engagement with the back side of the one substantially right triangular pyramidal projection 20 at the corner is not caught, the upper and lower storage containers T can be stacked in a state of being in close contact with each other. In addition, even when a stack of empty storage containers T is set in a storage container supply device such as a sorting device, there is no catch on the above-mentioned fitting portion, so that one by one from the stack of empty storage containers T is ensured. Therefore, the container T can be easily peeled off, and it is possible to reduce the peeling error of the container T in the container supply apparatus.

  Similarly, in this modified example, the outer surface 20a of the substantially right triangular pyramidal projections 20 formed at the corners of the four corners of the container substrate T is subjected to R processing (curved surface processing) at four locations. However, the present invention is not limited to this. For example, the outer surface 20a of the three substantially right-angled triangular pyramidal projections 20 may be R-processed. R processing (curved surface processing) may be applied to the outer surface 20a of the two substantially right triangular pyramid-shaped projections 20.

  The disclosed embodiments are merely examples and are not limited thereto. The present invention is defined by the terms of the claims, rather than the scope described above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

It is a top view explaining egg storage container T concerning the present invention. It is a side view explaining the container T for eggs concerning this invention. It is a partial detail drawing explaining the modification of the said container T of eggs, and another modification. It is a top view of the conventional container T for eggs. It is a side view explaining the malfunction which occurs when the conventional container T for eggs is laminated.
