Description

  The present invention relates to a storage tray for storing bags, loquats and the like and a packaging container having the storage tray.

For example, special packaging containers are used for packaging fruits such as strawberries. Conventionally, a packaging form in which a box-shaped container made of a synthetic resin sheet with an upper opening is used, and the baskets are accommodated in two layers inside the container, and a wrap film is applied to the upper opening side has long been used. .
However, in such a packaging form, due to vibration or the like generated when the container containing the jar is transported, the surface of the jar is pressed and scratched, or the surface rubs and the juice oozes out. There are things. In addition, there was a problem that it did not appear at the time of display and could not respond to the high-end market needs.

  For example, the fruit storage container disclosed in Patent Document 1 is such that a fruit storage film member for storing a fruit suspended in air has air permeability.

  Further, the packaging container disclosed in Patent Document 2 has a ventilation part that allows cold air from the lateral direction to pass through more efficiently than a ventilation hole opened in the wall part of the container. It allows for more direct and effective ventilation of the fruit that is present.

  The containers disclosed in Patent Documents 1 and 2 are configured so that each fruit can be individually accommodated, and the fruit is directly ventilated to contribute to maintaining freshness and maintaining quality. Here, when a container containing fruits is transported (transported by a vehicle, taken home after purchase, etc.), vibrations and the like are transmitted to the fruits. Under the influence of this vibration, the contained fruit may be moved in a vertical direction, a left-right direction, and a front-rear direction, or may be rotated, resulting in scratches on the fruit surface. It is necessary to minimize the occurrence of the “movement” of the fruit to maintain the quality and freshness of the fruit. However, in the containers disclosed in Patent Documents 1 and 2, there remains a problem that the movement of the fruit due to the vibration of the containers can be sufficiently suppressed and the quality deterioration cannot be suppressed.

  The main object of the present invention is to provide a fruit storage tray that can suppress the deterioration of the quality of an object to be stored (object to be stored) caused by vibration generated during container transportation. Moreover, the packaging container which has this is provided.

A packaging container will be described as an example. In addition, the number of fruits to be stored can be arbitrarily set to 2, 6, or 8, for example. In addition to the fruits such as strawberries and loquat, for example, the objects to be accommodated can be eggs, confectionery formed in a spherical shape, or the like.

[First Embodiment]
FIG. 1 is a perspective view illustrating an example of a packaging container having a storage tray according to the present embodiment.
A packaging container 10 shown in FIG. 1 is configured to include an outer box 101 formed in a bottomed rectangular tube shape, an inner space of the outer box 101, and a storage tray 102 for storing fruits. Note that the size and shape of the outer box 10 can be arbitrarily set according to the outer size, shape, and the like of the storage tray 102 formed in consideration of the number of fruits stored, the appearance when stored, and the like.

  The outer box 101 is formed using, for example, cardboard, a hard resin sheet, or the like. Note that the outer shapes of the outer box 101 and the storage tray 102 can be formed, for example, in a circular or elliptical shape in addition to a rectangle as shown in FIG.

The storage tray 102 is formed with a storage portion 103 for storing fruits and the like. The accommodating part 103 is formed in the site | part on the surface of the accommodating tray 102 so that adjacent fruit may not mutually contact according to the size etc. of a fruit, and each fruit may not contact the inner wall of the outer box 101. FIG. .
The storage tray 102 is formed to include a sheet formed by overlapping a sheet 102a, a sheet 102b, and a sheet 102c, which will be described later. Note that each of the sheets 102a, 102b, and 102c is a sheet formed using a flexible material. Details of the functional configurations of the storage tray 102 and the storage unit 103 will be described later.

  Further, the storage tray 102 provided in the internal space of the outer box 101 is provided at a position where the fruit and the bottom surface of the outer box 101 do not come into contact with each other when the fruit is stored in the storage unit 103. That is, the storage tray 102 is disposed in the internal space of the outer box 101 so that the distance between the bottom surface of the outer box 101 and the surface of the storage tray 102 facing the outer tray 101 is a distance that satisfies the above requirements.

  FIG. 2 is a top view of the packaging container 10. FIG. 3 is a diagram for explaining an example of the configuration of the accommodating portion 103. Fig.3 (a) is a schematic diagram of the AA cross section in FIG. 2, FIG.3 (b) is the elements on larger scale.

  As shown in FIG. 2, the accommodating portion 103 has a plurality of flexible flaps 104 formed by a plurality of cuts extending radially from the approximate center of a rectangular area set on the surface of the accommodating tray 102. It is formed. The flap 104 functions as a holding unit that holds the fruit stored in the storage unit 103. As shown in FIG. 3A, the flap 104 includes the flap 104a formed from the predetermined portion of the sheet 102a and the sheet 102b and the flap 104b formed from the predetermined portion of the sheet c. . Further, in the present embodiment, the description will be given by taking as an example a case where the eight flaps 104 are formed in equal divisions (every 45 [°] with reference to AA). The flap 104a may be referred to as a first flap and the flap 104b may be referred to as a second flap.

Here, the sheet 102a, the sheet 102b, and the sheet 102c constituting the storage tray 102 will be described.
The sheet 102a is a buffer sheet made of a porous material (for example, a flexible polyurethane foam) and formed of a foam material having open cells therein. The flexible polyurethane foam contains a relatively large number of open cells among the types of bubbles contained therein, has open cells, is extremely soft against compression, is lightweight, and has a restoring property. As a general flexible polyurethane foam, there is one having an expansion ratio of 10 to 60 times and an apparent density of 16 to 100 [kg / m ^ 3].

  In the packaging container 10 which concerns on this embodiment, since the sheet | seat 102a which comprises the flap 104a is comprised so that a fruit may be contacted, air permeability in a contact part can fully be ensured. In addition, the sheet 102a uses a standard product that is generally distributed such as a thickness of 2 [mm], 4 [mm], or the size of a fruit that is an object (for example, 2L, 3L, SE, Standard sizes such as DX) and thickness according to the weight can be adopted.

  The sheet 102b is a sheet material made of YUPO (registered trademark) paper, which is a kind of synthetic paper produced including, for example, polypropylene. The sheet 102b is formed using a material that has high water resistance and is less likely to cause a decrease in strength due to moisture, deformation, alteration, collapse, and the like, and is relatively strong in tensile elasticity, such as paper.

Further, as shown in FIG. 3B, the sheet 102b is bonded to the back surface (back surface) of the sheet 102a. That is, the flap 104a is formed by the sheet 102a and the sheet 102b arranged on the back side thereof. By bonding the sheet 102a and the sheet 102b together, the surface is soft and a repulsive force (force to push back the contained fruit) can be generated on the sheet 102a having no so-called “waist”. That is, the holding function of holding the fruit on the flap 104a can be exhibited. Thus, the sheet 102b functions as a reinforcing material that supplements (reinforces) the repulsive force of the sheet 102a. The bonded sheets 102a and 102b may be referred to as a first sheet.
In addition, when forming the said sheet | seat 102a with the raw material which produces a desired repulsive force, it can also comprise so that a reinforcing material like the sheet | seat 102b may not be used. In this case, the sheet 102a alone constitutes the first sheet.

The sheet 102c is a porous material (for example, rigid polyurethane foam), and is formed using a foamed sheet having closed cells inside. Rigid polyurethane foam contains a relatively large number of closed cells among the types of cells in its interior. Compared with flexible polyurethane foam, its compression strength is large, and when it is deformed, it is difficult to return even if stress is removed. This material has the characteristics of The sheet 102c may be referred to as a second sheet.
The flap 104b formed on the sheet 102c is a flexible flap formed in the same shape as the flap 104a at the projection position of the flap 104a on the sheet 102c.

  In addition, the sheet | seat 102a can select arbitrarily the raw material rich in flexibility, without impairing air permeability in the contact surface with a fruit. Further, the sheet 102c can be arbitrarily selected from a relatively harder material (for example, a resin sheet) when compared with the sheet 102a. Furthermore, the combination of the sheet | seat 102a and the sheet | seat 102c can be suitably combined according to the magnitude | size per one fruit which is a to-be-contained object, weight, etc., satisfy | filling the said conditions.

Thus, the flap 104b formed of the sheet 102c is configured to hold the fruit via the flap 104a. That is, in the storage tray 102, since the sheet 102c does not directly contact the fruit, even if the fruit in the stored state is in contact with the flap, the air permeability of the contact portion is maintained.
Further, the fruit stored in the storage tray 102 is held by the flaps 104a and 104b having different repulsive forces. Therefore, according to the magnitude | size of a motion of a fruit, for example, only the flap 104a follows quickly and curves, or the flaps 104a and b curve so that both may follow. Thus, since each flap follows the movement of a fruit independently or in cooperation, the hold property of the said fruit can be improved.

FIG. 4 is a diagram for explaining how fruits are accommodated in the packaging container 10.
FIG. 4A is a top view of the packaging container 10 containing the fruit F. FIG. FIG. 4B is a view for explaining the operation of the flaps 104 a and 104 b when the fruit F is accommodated in the packaging container 10.
As shown to Fig.4 (a), in this embodiment, two fruits F (for example, persimmon) are accommodated. In addition, FIG. 4A shows a state in which the fruit F is obliquely placed so as to be parallel to the diagonal line of the accommodation unit 103 as an example of the fruit direction (placement direction).

Moreover, as shown in FIG.4 (b), it pushes lightly downward so that the fruit F mounted in the accommodating part 103 may be hold | maintained with the force of about 200 [g] about by a flap.
When the fruit is pushed in, the tips of the flaps 104a and 104b move toward the lower outer side (the bottom side of the outer box 101) while spreading radially as shown in FIG. 4 (b). For example, as shown in FIG. 4B, each flap is in a state of being bent from the tip to the base. Then, the fruit F is pushed to a predetermined position, and the flaps 104a and 104b each hold the fruit F.

  In the state where the fruit F is held (accommodated state), only the flap 104a is in contact with the surface of the fruit F. FIG. 4B shows an example in which a space is formed between the back surface of the flap 104a and the front surface of the flap 104b. This is an example shown for the sake of explanation. For example, when storing the fruit F, the front surface of the flap 104a and the front surface of the flap 104b are kept in contact with each other (see FIG. 3A), and each tip is radiated. In some cases, it may move outward while spreading.

FIG. 5 is a diagram for explaining the movement of the fruit due to vibration during container transportation.
As shown in FIG. 5, forces in the vertical, horizontal, and longitudinal directions are applied to the fruit F by vibrations during container transportation. In the packaging container 10, the accommodation state of the fruit F is maintained by bending each flap in accordance with the movement of the fruit F. Moreover, according to the magnitude | size of the vibration at the time of carrying the packaging container 10, when the motion of a fruit is a relatively small motion (swing), it follows so that the flap 104a may absorb the shaking of the said fruit. Further, when the movement of the fruit is a relatively large movement (swing), the flap 104a and the flap 104b follow so as to absorb the shaking of the fruit.
As a result, the holdability of the fruit F is increased and the accommodation state is maintained, and for example, it is possible to efficiently prevent the fruit from sliding on the surface of the flap 104a and causing the surface of the fruit to be scratched (scratched). .

FIG. 6 is a view for explaining a verification result when vibration is applied to the packaging container 10 containing the fruit F. FIG.
In this verification, the packaging container 10 containing the fruit F (SE size) is subjected to vibration (simultaneous three-axis vibration of up / down / left / right / front / rear) using a transport packaging tester (for example, BF50UT manufactured by IDEX). In addition. The excitation conditions were 10 [Hz], 40 [Hz], and 10 [Hz] linearly varied in the left, right, front, back, and top and bottom, and one cycle 60 [second] was performed for 5 cycles. Under this condition, at 40 [Hz], the gravitational acceleration is 3 [G] in the vertical direction, 2.5 [G] in the left and right direction, and 0.6 [G] in the front and rear direction.

  Fig.6 (a) is a verification result at the time of putting a straw in the conventional common fruit tray and adding a vibration. In this case, it can be seen that the baskets accommodated in the recesses move greatly, such as jumping out of the recesses of the tray. In this case, many scratches and the like are generated on the heel surface.

FIG. 6B shows a state in which the bag is accommodated in the packaging container 10 and before the vibration is applied.
FIG.6 (c) has shown the accommodation state of the bag after applying a vibration in the state of FIG.6 (b). As shown in FIG. 6 (c), it can be seen that there is no significant change in the direction (mounting direction) of the heel before and after excitation. That is, it can be seen that the packaging container 10 according to the present embodiment exhibits a sufficient fruit holding performance.

FIG. 6D shows a state of the surface of the sheet 102a when the wrinkles are removed from the state of FIG. Only a few spots were generated in the area surrounded by the dotted line in the figure, and no other noticeable spots were found. That is, there are no noticeable scratches or the like on the heel surface.
From the verification result, the configuration like the packaging container 10 can effectively hold the object and restrict the movement of the object due to vibration or the like. Moreover, it becomes possible to sufficiently suppress the occurrence of scratches on the fruit surface.

FIG. 7 is a diagram illustrating another example of the configuration of the accommodating portion 103.
FIG. 7A shows a case where four flaps are formed by a cut extending diagonally from the approximate center of the rectangular region. FIG. 7B shows a case where 16 flaps are equally divided by cuts extending radially from substantially the center of the rectangular area.
In this way, the number of flaps formed in the accommodating portion 103 is, for example, the surface shape and size of the object to be accommodated, for example, if the “cherry” is smaller than the ridge, the flap surface area is formed. Can be set to fit the object.

  Thus, the packaging container 10 which concerns on this embodiment can improve the followability of the flap with respect to a motion of a fruit by hold | maintaining (hold | maintaining) a fruit with two flaps from which repulsive force differs. Thereby, the accommodation state of a fruit is maintained effectively and the quality fall of the fruit which makes a factor the vibration etc. which arise at the time of conveyance of a packaging container, etc. can be suppressed efficiently. In addition, even when eggs, spheres and other confectionery are contained, the same effect can be obtained, such as efficiently suppressing the occurrence of scratches (scratches) on the surface. Can do.

[Second Embodiment]
In the first embodiment, description will be made mainly on the point that the occurrence of “movement” of the fruit when the packaging container 10 is transported in a substantially horizontal state can be suppressed to the maximum to maintain the quality and freshness of the fruit. Advanced. For example, when the number of objects to be accommodated (contained objects) is increased from 2 to 8, the width of the packaging container inevitably increases. In addition, as the width of the packaging container increases, the number of cases that it may hit when being carried increases, so the safety during transportation may be impaired, and the quality of the contained items may be adversely affected. The nature will increase.
This embodiment demonstrates the structure for suppressing effectively the influence of the vibration which arises when carrying the packaging container which accommodated the fruit etc. in the substantially vertical state, ie, the state which stood the packaging container. In addition, about the functional structure already demonstrated in 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  FIG. 8 is a diagram illustrating an example of a packaging container having a storage tray according to the present embodiment. Fig.8 (a) is a top view of the packaging container 20 which concerns on this embodiment, FIG.8 (b) is a figure for demonstrating the structure for accommodating the fruit etc. in the packaging container 20. FIG. In the present embodiment, a packaging container formed in a so-called book-type box is described as an example, but the present invention is not limited to this shape. Moreover, the functional configuration of the storage tray 201 included in the packaging container 20 has the same functional configuration as the storage tray 102 already described in the first embodiment, and the number of objects to be stored is different.

  As shown in FIG. 8B, the packaging container 20 is formed in a storage tray 201 for storing fruits, a bottomed rectangular tube shape, a box 202 in which the storage tray 201 is disposed in an internal space thereof, and an opening of the box 202. It has a lid 201 that closes the part. The packaging container 20 also includes a holding sheet 210 (sometimes referred to as a third sheet) disposed so as to face the storage tray 201 when the lid 203 is closed. The holding sheet 210 can be configured to be detachable from the lid 203. Moreover, the fastener 20a shown to Fig.8 (a) is a member for making the said lid | cover 203 and the box 202 closely_contact | adhere when the lid | cover 203 is closed, and maintaining the state.

  In addition, in FIG.8 (b), the accommodation tray 201 in which the accommodating part (area | region enclosed with the broken line in the figure) for accommodating the fruit which is a to-be-contained object is formed is shown as an example. Depending on the size of the fruit, etc., this accommodating part is formed in an arbitrary number of portions on the surface of the accommodating tray 201 so that adjacent fruits do not contact each other and each fruit does not contact the inner wall of the box 202. can do.

  Further, a plurality of flaps 204 having the same configuration as that already described in the first embodiment is formed in the accommodating portion. The flap 204 is formed by a plurality of cuts extending radially from the approximate center of a rectangular area set on the surface of the storage tray 201, and has flexibility. The flap 204 is configured to include two flaps 204a and 204b (see FIG. 9) similarly to the flap 104 of the first embodiment, and the flap 204b is configured to hold the fruit via the flap 204a. The

  The holding sheet 210 has a plurality of substantially circular holding portions (recesses) formed on the sheet surface. The recesses formed in the holding sheet 210 are respectively formed at positions where the centers thereof substantially coincide with the centers of the accommodating portions that face each other when the lid 203 is closed. The recess holds the object to be stored at a position different from the storage tray 201 when the lid 203 is closed. Details of the configuration of the holding sheet 210 will be described later.

FIG. 9 is a diagram for explaining an example of the configuration of the holding sheet 210. FIG. 9A is a side view showing an example of a state in which the fruit F is stored in the storage tray 201 and before the lid 203 is closed, and FIG. 9B is a view in which the lid 203 is closed. It is a side view showing an example of a state. 9 (a) and 9 (b), the fruit F accommodated in one accommodating portion of the accommodating tray 201 is shown with the packaging container 20 placed horizontally.
The holding sheet 210 (see FIG. 8B) includes the cushioning sheets 210a and 210b and the bubble cushioning material 210c shown in FIG. The buffer sheets 210a and 210b are sheets made of a porous material (for example, flexible polyurethane foam) and formed of a foam material having open cells therein. The bubble cushioning material 210c functions as a cushioning material for filling the gap between the lid 203 and the cushioning sheet 210b. The thickness of the foam cushioning material 210c is adjusted according to, for example, the size of the fruit to be accommodated and the thickness of the cushioning sheets 210a and 210b. In this way, the entire thickness of the holding sheet 210 is adjusted.

As shown in FIG. 9A, the buffer sheet 210a is formed with a hole (for example, a round hole having a diameter of 20 [mm]) for forming the above-described recess. Further, as shown in FIG. 9B, the hole is formed at a position and size such that the inner edge of the concave portion of the holding sheet 210 contacts the surface of the fruit F when the lid 203 is closed.
The thickness of each of the buffer sheets 210a and 210b constituting the holding sheet 210 is determined according to the size of the fruit or the like stored in the storage tray 201 (for example, standard sizes such as 2L, 3L, SE, and DX). can do. In addition, the buffer sheets 210a and 210b constituting the holding sheet 210 can be formed as, for example, an integrally molded product in addition to being formed as independent sheets. Furthermore, it is possible to form the entire holding sheet 210 as an integrally molded product and form a recess on the surface thereof.

  Further, in order to enhance the holding property of the fruit F by the holding sheet 210 and the storage tray 201, the thickness is configured such that the fruit F is pushed toward the storage tray 201 by the holding sheet 210 when the lid 203 is closed, for example. Suppose that Even in such a case, as shown in FIG. 9 (b), the flaps 204a and 204b are flexed by following the movement of the fruit independently or in cooperation with each other. Maintenance and freshness can be maintained.

9 (a) and 9 (b), fruit F is shown as having a shape that has a gentle undulation even when viewed from the front of the figure, but in the actual fruit, the undulation is not equal to the left and right. There are many. For example, if the fruit F is a strawberry, there is a portion (the top of the undulation) where the undulation height is the highest in the direction relatively closer to the side than the tip side.
For example, the concave portion of the holding sheet 210 (the buffer sheet 210a) corresponds to a portion around the portion where the undulation height is highest (the top of the undulation) when the object is stored in the storage tray 201, that is, the portion surrounding the top of the undulation. It can also be formed so as to hold the object to be stored at a position different from that of the storage tray 201. In this case, the holdability of the fruit F can be further improved. In this case, the center of the concave portion formed in the holding sheet 210 does not coincide with the center of the accommodating portion facing when the lid 203 is closed, resulting in deviation.

FIG. 10 is a diagram for explaining that the influence of vibration generated when the packaging container 20 is carried in a substantially vertical state is effectively suppressed. FIG. 10 shows the fruit F accommodated in one accommodation portion of the accommodation tray 201 with the packaging container 20 standing vertically.
In the state where the packaging container 20 containing fruits and the like is stood up, as shown in FIG. 10, the load toward the arrow direction (vertically downward) of the fruit F is applied to the storage portion of the storage tray 201 (the lower flap as viewed from the front of the drawing). 204a, 204b) and the lower inner edge of the recess of the buffer sheet 210a. At this time, the lower flaps 204a and 204b as viewed from the front of the figure follow the movement of the fruit F by the flaps independently or in cooperation, and the upper flaps 204a and 204b also follow the movement of the fruit F. Move. Therefore, the holdability of the fruit F is not impaired by the action of the concave portions of the upper and lower flaps and the holding sheet 210 (buffer sheets 210a and 210b).
In this way, even when the packaging container 20 is stood and carried, occurrence of “movement” of an object (for example, fruit F) due to vibrations or the like occurring at that time is suppressed to the maximum. become.

FIG. 11 is a view for explaining an example of a handle for carrying the packaging container 20 in a substantially vertical state.
FIG. 11A is a view showing a state in which the handle M1 is attached to the upper bottom surface when the packaging container 20 is in a substantially vertical state.
11 (b) and 11 (c) wrap the three surfaces (front surface, lower bottom surface, and back surface) of the packaging container 20 in a standing state using a sheet member, and a grip portion formed of a long hole on the upper surface of the packaging container 20. It is a figure which shows the handle M2 which formed. The handle M2 can be attached and detached as necessary, for example, when the packaging container 20 is stood and carried. Further, as shown in FIGS. 11B and 11C, the handle M <b> 2 causes the sheet member in contact with the front surface / back surface of the packaging container 20 to be in close contact with the band member M <b> 2 a formed in a band shape. Thereby, it is possible to prevent the handle M2 from dropping from the packaging container 20 due to shaking during carrying.
The handles M1 and M2 for carrying the packaging container 20 in a substantially vertical state are merely examples, and components for carrying the packaging container 20 in a standing state are not limited thereto.

As described above, the packaging container 20 according to the present embodiment can effectively suppress the influence of vibration that occurs when the fruit is stored and carried in a substantially vertical state, that is, in a state where the packaging container is stood. As a result, the storage state of the fruit is effectively maintained, and it is possible to efficiently suppress deterioration in the quality of the fruit due to vibrations and the like that occur during transportation of the packaging container, etc., and safety and efficiency during transportation. It is possible to improve the performance.
