Description

Technical Field

[0001] The present invention relates to a storage container, in particular to a storage container for storing food and the like. Background Art

[0002] A typical refrigerator has a refrigerator, freezer, and vegetable compartment as storage compartments. In recent years, with the widespread use of frozen foods, freezer compartments have become increasingly larger, sometimes resulting in insufficient capacity for the vegetable compartment. One solution to this problem is to store food such as vegetables in storage containers and then store these containers in the refrigerator.

[0003] Patent Document 1 (Japanese Patent Application Laid-Open No. 8-170873) describes an example of a storage container. This storage container is roughly rectangular in shape, with a slit-shaped opening at the bottom to form a cold air vent. Cold air enters the storage container through the cold air vent, thereby cooling vegetables and other foods stored in the storage container to a predetermined refrigerated temperature range.

[0004] However, the storage containers of the above-mentioned background art have room for improvement from the viewpoint of freshness preservation of stored food.

[0005] Specifically, since the storage container of the background art has slits, moisture contained in the stored vegetables and the like is discharged to the outside of the container through the slits, which causes the freshness of the vegetables to decrease prematurely.

[0006] Furthermore, since the slits are formed on the bottom surface and the side surfaces of the container, there is also a problem that dust may intrude into the interior of the storage container through the slits.

[0007] The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a storage container capable of well maintaining the freshness of stored vegetables. Summary of the Invention

[0034] The interior of the storage compartment is divided into a refrigerator compartment 12, a freezer compartment 13, and a vegetable compartment 14. The refrigerator compartment 12, located at the top, and the freezer compartment 13, located below it, are separated by a partition wall 20. The freezer compartment 13 and the vegetable compartment 14, located below it, are separated by a partition wall 21. The partition walls 20 and 21 have the same insulating structure as the insulated cabinet 11. The vegetable compartment 14 can be cooled to a refrigerated temperature range suitable for storing vegetables, fruits, etc.

[0035] The front surface of the insulated housing 11 is open. Openable and closable insulated doors 15, 16, and 17 are located at the openings corresponding to the refrigerator compartment 12, freezer compartment 13, and vegetable compartment 14, respectively. These doors 15, 16, and 17 have substantially the same insulation structure as the insulated housing 11. The upper and lower sides of the insulated door 15 are rotatably supported on the insulated housing 11. The insulated doors 16 and 17 are supported on the insulated housing 11 so as to be freely withdrawable toward the front of the refrigerator 10.

[0036] An air supply duct 22 is provided on the rear side of the freezing chamber 13. The air supply duct 22 is connected to the freezing chamber 13 and is used to supply cold air. The air supply duct 22 is separated from the freezing chamber 13 by a partition made of synthetic resin.

[0037] A cooling chamber 18 is formed by a partition body made of synthetic resin at the rear of the air supply duct 22. Inside the cooling chamber 18, a cooler 19 for cooling the air circulating in the storage chamber is provided.

[0038] Cooler 19 is a fin-tube evaporator, etc. It is connected to compressor 25, a radiator (not shown), and capillary tubes (not shown) via refrigerant piping. This constitutes a vapor-compression refrigeration cycle. Furthermore, compressor 25, a portion of the radiator, and a cooling fan (not shown) that blows air to the radiator are housed in an equipment compartment located at the lower rear of refrigerator 10.

[0039] An air vent is formed in the upper portion of cooling chamber 18. This vent is an opening connected to air supply duct 22. A blower 24 is installed in this vent to circulate cold air. Blower 24, for example, an axial flow blower, directs air cooled by cooler 19 from cooling chamber 18 to the storage compartments. Furthermore, a return air vent is formed in the lower portion of cooling chamber 18. This vent returns air from freezer compartment 13 to cooling chamber 18.

[0040] An air supply duct 23 is formed behind the refrigerating chamber 12, which is partitioned by a partition made of synthetic resin and is used to supply cold air to the refrigerating chamber 12. The air supply duct 23 is connected to the air supply duct 22 and is connected to the refrigerating chamber 12 via an air outlet.

[0041] The refrigerator 10 includes an air supply duct (not shown) that connects the refrigerating chamber 12 and the vegetable chamber 14 and supplies cold air to the vegetable chamber 14, and a return duct (not shown) that connects the refrigerating chamber 12 or the vegetable chamber 14 and the cooling chamber 18 and returns cold air from the refrigerating chamber 12 or the vegetable chamber 14 to the cooling chamber 18. Furthermore, dampers (not shown) may be provided in the air supply duct 22 or the air supply duct 23 to control the flow rate of cold air supplied to the storage chamber and appropriately maintain the temperature inside the storage chamber.

[0042] By the refrigerator 10 having the above-described structure, the refrigerating chamber 12 and the vegetable chamber 14 are cooled to a predetermined refrigerating temperature range, and the freezing chamber 13 is cooled to a predetermined freezing temperature range.

[0043] Furthermore, a storage container 30 is provided in the refrigerator compartment 12. The storage container 30 is a synthetic resin container that stores food such as vegetables, fruit, and cut vegetables. By placing the storage container 30 in the refrigerator compartment 12, the air cooling the refrigerator compartment 12 can also cool the interior of the storage container 30 to a refrigerated temperature range, effectively maintaining the freshness of the vegetables and other items in the storage container 30.

[0044] Furthermore, by providing the storage container 30 provided in the refrigerator compartment 12 , even when the capacity of the vegetable compartment 14 is reduced due to the increase in the capacity of the freezer compartment 13 , vegetables and the like can be stored in the storage container 30 provided in the refrigerator compartment 12 .

[0045] Figure 2A This is a perspective view of the storage container 30 as viewed from above. Figure 2B It is a perspective view of the storage container 30 as viewed from below.

[0046] Reference Figure 2A and Figure 2B The storage container 30 mainly comprises a container portion 31 and a cover portion 36 for closing the upper opening of the container portion 31. The storage container 30 also comprises Figure 6 The filter portion 37 shown, Figure 5B The seal 38 and Figure 5C The connecting portion 39 is shown.

[0047] When storing vegetables and the like in the storage container 30, the user opens the container. Figure 1 The user opens the insulated door 15 shown and removes the storage container 30 from the refrigerator compartment 12. Furthermore, the user removes the lid 36 from the container 31, stores vegetables and the like in the container 31, and closes the upper opening of the container 31 with the lid 36. The user then returns the storage container 30 to the refrigerator compartment 12 and closes the insulated door 15.

[0048] When taking out vegetables and the like from the storage container 30, the user removes the lid 36 from the container portion 31, takes out the vegetables and the like from the interior of the container portion 31, and then closes the upper opening of the container portion 31 with the lid 36. The user then returns the storage container 30 to the refrigerator compartment 12 and closes the insulating door 15.

[0049] The container portion 31 is a substantially box-shaped member with an open upper end, and is integrally formed of, for example, a transparent synthetic resin. By forming the container portion 31 from a transparent resin, the user can visually check the vegetables and the like stored in the storage container 30 through the container portion 31 without removing the cover 36 from the container portion 31. For a detailed structure of the container portion 31, refer to Figure 3 etc. will be discussed later.

[0050] The lid 36 is a member made of a synthetic resin having a substantially plate-like shape that closes the opening of the container 31. Figure 4A The cover 36 is made of a synthetic resin having excellent flexibility so as to be easily bent by a user's operation.

[0051] Reference Figure 2B , four first alignment portions 40 are formed on the lower surface of the bottom portion 32 of the container portion 31. Figure 2A , four second alignment portions 41 are formed on the upper surface of the cover portion 36. Moreover, when viewed from above, the first alignment portion 40 of the container portion 31 and the second alignment portion 41 of the cover portion 36 are arranged in a manner that is substantially overlapped. Figure 2A As shown in FIG. 4 , the second alignment portion 41 is a portion where the upper surface of the cover portion 36 is partially concave. Figure 2B As shown, the first alignment portion 40 is a portion where the bottom surface of the container portion 31 is partially convex.

[0052] Therefore, in Figure 1When multiple storage containers 30 are stacked vertically in the refrigerator compartment 12, the first alignment portion 40 of the upper storage container 30 can be inserted into the second alignment portion 41 of the lower storage container 30. This allows the multiple storage containers 30 to be stacked in a well-balanced manner.

[0053] Figure 3 31 is a perspective view of the container portion 31 viewed from above. The container portion 31 has a bottom surface 32 and side surfaces 33, and a substantially rectangular opening is formed at the upper end. The container portion 31 is made of an integrally molded transparent synthetic resin.

[0054] The bottom surface 32 is a generally rectangular portion. The side surfaces 33 are portions extending upward from the four sides of the bottom surface 32. The storage space 34 is a generally rectangular parallelepiped space surrounded by the bottom surface 32 and the four side surfaces 33.

[0055] The handle portion 351 is a plate-shaped portion that protrudes forward from the upper end of the side surface 33 that forms the front surface. The handle portion 351 includes an upper handle portion 352 that extends approximately parallel to the front from the upper end of the side surface 33, and a lower handle portion 353 that extends downward from the front end of the upper handle portion 352. A downward-facing opening is formed in the handle portion 351, into which a user can insert a finger from below. Therefore, even if the storage container 30 is placed high inside the refrigerator compartment 12, the user can easily remove the storage container 30 by inserting a finger from below into the opening of the handle portion 351.

[0056] Figure 4A This is a perspective view of the cover portion 36 as viewed from above. Figure 4B This is a perspective view of the cover portion 36 as viewed from below.

[0057] Reference Figure 4A and Figure 4B The cover 36 has a cover body 361 and a wall 362. In addition, a Figure 5A The sealing support portion 363 shown in FIG.

[0058] Reference Figure 4A The cover body 361 is a substantially plate-shaped member that is substantially rectangular in shape. A peripheral wall portion 364 is erected upward from the peripheral edge of the cover body 361 .

[0059] A contact portion 366 and a notch portion 365 are formed on the peripheral edge of the cover body 361 .

[0060] The abutment portion 366 is formed at the four corners of the cover body 361. In addition, the abutment portion 366 is also formed in the middle of each side of the cover body 361. The abutment portion 366 is a portion where the peripheral portion of the cover body 361 becomes thicker, and its lower surface is flat. Figure 1 As shown, when the container portion 31 is closed by the lid portion 36 , the lower surface of the contact portion 366 of the lid portion 36 contacts the upper end portion of the container portion 31 .

[0061] Notches 365 are formed between the abutment portions 366 on the peripheral edge of the lid 36. The notches 365 are cut out from the side of the peripheral wall 364, forming a downwardly and inwardly inclined surface. When a user removes the lid 36 from the container 31, they can hook their fingers on the inclined surface of the notches 365 to pull the lid 36 away from the container 31.

[0062] Reference Figure 4B The wall portion 362 is a wall-shaped portion that stands upright from the peripheral portion of the cover body 361 toward the bottom. The wall portion 362 is continuously formed along the peripheral portion of the cover portion 36. A seal support portion 363 that supports the seal portion 38 is formed on the wall portion 362. The structure of the seal support portion 363 is shown in FIG. Figure 5B etc. will be discussed later.

[0063] The seal portion 38 is a substantially annular member that seals the gap between the container portion 31 and the lid portion 36. The seal portion 38 is made of a synthetic resin having excellent flexibility, such as rubber or silicone resin. The seal portion 38 is supported by the seal support portion 363. For details on the structure of the seal portion 38, refer to Figure 5B To be described later.

[0064] The filter unit 37 is provided on the lower surface of the lid 36 and is provided on the path that connects the storage space 34 of the storage container 30 to the outside. The filter unit 37 has a filter function that ensures ventilation and suppresses the flow of water to the outside. This can suppress the loss of water from the vegetables stored in the storage container 30. The structure of the filter unit 37 is described in detail in the following. Figure 6 etc. will be discussed later.

[0065] Figure 5A is a side cross-sectional view showing the cover portion 36, Figure 5B 3 is a side cross-sectional view showing the wall portion 362 and the like arranged on the left side, Figure 5C 1 is a side cross-sectional view showing the filter support portion 372, etc. These cross-sectional views correspond to Figure 4A AA cuts the upper thread.

[0066] Reference Figure 5AThe peripheral wall portion 364 extends upward from the upper surface of the left and right ends of the cover body 361. Furthermore, the wall portion 362 extends downward from the lower surface of the left and right ends of the cover body 361. The filter portion 37 is provided on the lower surface of the cover body 361 and is located on the right side.

[0067] Reference Figure 5B A wall portion 362 is erected downward from the left end portion of the cover body 361. The lower portion of the wall portion 362 protrudes outward, that is, to the left, to form a seal support portion 363. The two seal support portions 363 are spaced apart by a predetermined interval.

[0068] The cross-section of the sealing portion 38 is a substantially rectangular shape elongated in the left-right direction. The sealing portion 38 is inserted between the sealing support portions 363 from the outside, i.e., the left side. This structure allows the sealing portion 38 to be inserted into the sealing support portions 363 by utilizing the elasticity of the annular sealing portion 38 itself.

[0069] Reference Figure 5C The filter unit 37 is installed between the storage space 34 and the outside of the storage container 30. The filter unit 37 allows ventilation between the storage space 34 and the outside and suppresses the outflow of moisture from the storage space 34 to the outside.

[0070] The filter unit 37 includes a filter 371 , a filter support portion 372 , and a filter internal space 373 .

[0071] The filter 371 is, for example, a paper filter. The filter support portion 372 supports the filter 371 at a predetermined position. The filter internal space 373 is a substantially cylindrical space formed inside the filter support portion 372 and is separated from the storage space 34 by the filter 371. The structure of the filter 371 and the filter support portion 372 is shown in FIG. Figure 6 To be described later.

[0072] On the right end of the filter unit 37, a wall portion 362 is erected downward from the lower surface of the cover body 361. Two seal support portions 363 are erected rightward from the lower portion of the wall portion 362. The seal portion 38 is inserted between the seal support portions 363.

[0073] A through-hole 42 is formed above the wall 362. The through-hole 42 is a hole extending horizontally through the wall 362. The left end of the through-hole 42 communicates with the filter internal space 373. The right end of the through-hole 42 is open to the outside, that is, to the right.

[0074] The communication portion 39 is a path that connects the storage space 34 and the outside via the filter portion 37. Figure 5CIn FIG, a communication portion 39 is indicated by a dashed line. The communication portion 39 is a path from the storage space 34 to the filter 371, the filter internal space 373, the through portion 42, and the outside.

[0075] Thus, the communication portion 39 uses the through-portion 42 of the wall portion 362 as a portion of its path. Specifically, a portion of the communication portion 39 is formed between the seal support portion 363 and the wall portion 362 located above the seal support portion 363, i.e., on the side of the lid body 361. This ensures the airtightness of the interior of the storage space 34 by the seal portion 38, while allowing ventilation between the interior and exterior of the storage space 34 via the through-portion 42.

[0076] Figure 6 It is an exploded perspective view showing the filter support portion 372 .

[0077] Reference Figure 6 The filter support portion 372 includes a filter support cover portion 374 , a filter 371 , a filter support plate portion 375 , and a filter support cylinder portion 376 from the bottom side.

[0078] The filter support cover 374 is a flat cylindrical container with an upper opening. The right side of the filter support cover 374 is formed with a notch ( Figure 6 In addition, a plurality of ventilation holes for ventilation are formed on the lower surface of the filter support cover 374.

[0079] The filter 371 is a substantially paper-shaped filter that allows air to pass through while restricting the passage of moisture.

[0080] The filter support plate portion 375 is a plate-shaped member having a substantially circular plate shape and is formed with a plurality of ventilation holes for ventilation.

[0081] The filter supporting cylinder 376 is a portion provided upright downward from the lower surface of the cover body 361 in a substantially cylindrical or annular shape.

[0082] Filter 371 is sandwiched between the bottom surface of filter support cover 374 and filter support plate 375. Filter support portion 372 is formed by assembling filter support cover 374, which assembles filter support plate 375 and filter 371, from below into filter support cylinder 376. Furthermore, the holes formed in the bottom of filter support cover 374 and the holes formed in filter support plate 375 overlap, allowing for ventilation.

[0083] Figure 7 It is a cross-sectional perspective view specifically showing the communication portion 39 that connects the storage space 34 of the storage container 30 with the outside.

[0084] The upper opening of the container portion 31 is sealed by the lid portion 36. The gap between the upper opening of the container portion 31 and the lid portion 36 is sealed along its entire circumference by the sealing portion 38. Specifically, when the upper opening of the container portion 31 is sealed by the lid portion 36, the outer end of the sealing portion 38 bends upward and abuts against the inner surface of the side portion 33. As a result, the storage space 34 of the container portion 31 is substantially sealed.

[0085] Even in this state, ventilation is provided between the storage space 34 and the outside through the communication portion 39. Specifically, a small amount of air circulates between the storage space 34 of the storage container 30 and the outside via the communication portion 39. Specifically, the communication portion 39 allows ventilation between the storage space 34 and the outside via the holes in the filter support cover 374, the filter 371, the holes in the filter support plate 375, the filter internal space 373, and the through-portion 42.

[0086] Furthermore, a portion of the communication portion 39 is formed so as to extend laterally from between the upper end 35 of the side surface 33 of the container portion 31 and the lid portion 36. Specifically, a gap is formed between the upper end 35 of the side surface 33 of the container portion 31 and the notch 365 of the lid portion 36. The communication portion 39 extends laterally through this gap to the storage container 30. Therefore, air entering the storage space 34 through the communication portion 39 flows laterally, thereby preventing dust and the like from entering the storage space 34 through the communication portion 39.

[0087] According to this embodiment, the following main effects can be achieved.

[0088] Reference Figure 7 By forming a portion of the communication portion 39 between the container portion 31 and the cover portion 36, the communication portion 39 is formed for maintaining the freshness of the stored storage items, so there is no need to form an opening in the container itself.

[0089] Reference Figure 5C By forming a portion of the communicating portion 39 in the wall portion 362 closer to the cover body 361 than the seal support portion 363 , a certain degree of airtightness can be ensured by the sealing portion 38 , and ventilation of the communicating portion 39 can be utilized.
