Description

Technology Field

[0001] The present invention relates to packaging technology for fruits and vegetables that are vulnerable to external impact and pressure, such as strawberries. More specifically, it relates to a packaging container for strawberries stacked vertically to reduce damage to the raw material caused by lateral pressure, collision between strawberries, and shaking during distribution that may occur in conventional packaging methods where strawberries are stacked in a horizontal position.

[0002] In addition, the present invention relates to a strawberry vertical loading packaging container that maintains a vertical loading state in which the stem or base of the strawberry faces downward and the tip of the strawberry faces upward, thereby transferring the load of the strawberry downward rather than to the side of the strawberry, and mitigating surface damage to the strawberry caused by vibration or impact occurring during distribution and delivery.

[0003] In addition, the present invention relates to a vertical stacking packaging container for strawberries that can accommodate strawberries individually standing upright, taking into account the natural shape and actual consumption pattern of the strawberries, and reduces the problem where damage to some strawberries during delivery leads to a deterioration in the quality of surrounding strawberries. Background Technology

[0005] Strawberries are a fruit and vegetable with soft flesh and delicate surface texture, and can be easily damaged by external impact or repeated shaking during packaging, storage, transportation, and display processes after harvest. In particular, because strawberries have a softer surface and higher moisture content compared to other fruits, if they come into contact with each other inside the packaging container or repeatedly bump against the inner wall of the container, surface denting, flesh damage, moisture leakage, and quality deterioration can progress rapidly.

[0006] Conventional strawberry packaging methods generally involve arranging multiple strawberries horizontally inside a packaging container. In this horizontal stacking method, the wide side of the strawberry comes into contact with the bottom of the packaging container or the side of an adjacent strawberry, and vibrations and shocks generated during the movement or delivery of the packaging container are easily transmitted to the side of the strawberry. Consequently, repeated pressure and friction may occur on the side of the strawberry, and damage to the raw material may occur as the surface tissue of the strawberry is crushed or burst.

[0007] In particular, a standard 500g strawberry packaging container typically holds around 15 strawberries, but damage to some strawberries occurs frequently during distribution and delivery. For instance, if some strawberries inside the container are damaged by pressure or impact during shipping, moisture may be released from the damaged strawberries. This released moisture can increase the humidity inside the container or come into contact with the surfaces of surrounding strawberries. In this case, the quality degradation of the initially damaged strawberries can spread to nearby healthy strawberries, potentially leading to mold growth or a chain reaction of spoilage.

[0008] Furthermore, the existing horizontal stacking method fails to adequately consider the natural shape of strawberries and their actual consumption patterns. Strawberries generally have a shape that is relatively wide at the stem or base and narrows toward the tip. Consumers often remove the stem or base after washing before consuming them, and in cake or dessert decorations, strawberries are frequently used with the stem or base positioned at the bottom and the tip facing upward. Considering these natural shapes and usage patterns, stacking strawberries in a horizontal position can transfer load in a way that unnecessarily compresses the sides of the strawberries.

[0009] While conventional packaging containers may be suitable for transporting strawberries within a confined space, they have limitations in stably maintaining the position of individual strawberries or reducing lateral pressure against vibrations and shocks during delivery. Furthermore, when strawberries are arranged in close contact with each other inside the packaging container, an impact applied to one strawberry can be directly transmitted to adjacent strawberries, and strawberries may repeatedly collide with each other within the limited space of the container.

[0010] Therefore, there is a need for new packaging technology that supports strawberries longitudinally so that the load is transferred downward rather than to the sides, stably accommodates each strawberry individually, and reduces damage caused by vibrations and shocks during distribution and delivery. Additionally, there is a need for packaging technology for stacking strawberries that prevents damage to some strawberries from spreading to the deterioration of surrounding quality, and maintains a stacking condition that considers the natural shape of the strawberries and their actual consumption patterns.

[0012] Korean Patent Publication No. 10-2026-0027444 (Eco-friendly strawberry packaging container) The problem to be solved

[0013] The present invention aims to provide a strawberry vertical loading packaging container capable of individually accommodating strawberries in a vertical direction, such that the lower part to which the stem is attached or the bottom part exposed after the stem is removed faces downward and the tip of the strawberry faces upward, without stacking the strawberries in a horizontal position.

[0014] The present invention aims to provide a strawberry vertical stacking packaging container that can reduce lateral pressure damage to strawberries caused by vibration and shock during distribution and delivery by stacking strawberries vertically, taking into account the natural shape and actual consumption pattern of strawberries, and ensuring that the load of the strawberries is transferred in the downward direction rather than to the sides of the strawberries.

[0015] The present invention aims to provide a strawberry vertical stacking packaging container that can accommodate and support each strawberry individually, thereby reducing direct collisions between strawberries or pressure caused by them being in close contact with each other inside the packaging container.

[0016] The present invention aims to provide a strawberry vertical stacking packaging container that allows the lower and middle outer edges of the strawberries to be accommodated by pocket cells to a depth greater than a certain level, thereby stably maintaining the vertical orientation of the strawberries and reducing tilting of the strawberries or displacement of their position within the packaging container due to shaking during transport.

[0017] The present invention aims to provide a strawberry vertical stacking packaging container that can mitigate vibrations or shocks being directly transmitted to the surface of the strawberry during distribution by causing the pocket cells to elastically deform or be displaced together with the strawberry in response to the movement of the strawberry.

[0018] The present invention aims to provide a vertical stacking packaging container for strawberries that reduces the spread of damage, moisture, or rot occurring in some strawberries to the deterioration of quality of surrounding strawberries, and can more stably maintain the freshness and marketability of the packaged strawberries.

[0019] The objectives of the present invention are not limited to those mentioned above, and may include objectives related to improving the vertical stacking stability of strawberries, alleviating lateral pressure, improving individual solubility, mitigating shock during delivery, and improving quality retention that can be derived from the configuration of the present invention. means of solving the problem

[0021] A strawberry vertical stacking packaging container according to one embodiment of the present invention comprises: a lower tray; a container body seated on the lower tray and having a plurality of receiving grooves formed therein; a plurality of pocket cells disposed in each of the plurality of receiving grooves; a sealing part disposed on the upper side of the container body and restricting the upward displacement of each of the plurality of pocket cells; and a sheet body seated on the upper side of the sealing part and having a plurality of holes formed therein corresponding to the plurality of receiving grooves. and a lid portion that covers the upper side of the sheet body and is coupled to the lower tray; wherein each of the plurality of pocket cells individually accommodates the strawberry in a vertical direction such that the lower portion to which the strawberry stem is attached or the bottom portion exposed after the stem is removed faces downward and the tip portion of the strawberry faces upward; each of the plurality of pocket cells has a concave cup shape that surrounds the lower outer and middle outer portions of the strawberry in a circumferential direction, and accommodates the strawberry such that at least 55% of the strawberry is located inside each of the plurality of pocket cells based on the total height-direction length from the lower portion to which the strawberry stem is attached or the bottom portion exposed after the stem is removed to the tip portion of the strawberry; each of the plurality of pocket cells supports the strawberry so that the load of the strawberry is transferred to the bottom of the strawberry rather than to the side of the strawberry; and each of the plurality of pocket cells mitigates the shock transmitted to the strawberry by being displaced together with the strawberry with the container body when vibration or shock occurs during distribution.

[0022] Each of the above plurality of pocket cells can be formed from any one of a silicone-based film, a soft synthetic resin film, or an elastic polymer film.

[0023] Each of the above plurality of pocket cells can be elastically deformed in response to the movement of the strawberry.

[0024] Each of the above plurality of pocket cells may include a seating ledge that protrudes outwardly from the upper circumference of each of the plurality of pocket cells.

[0025] In the above container body, a pocket cell seating portion may be formed along the outer circumference of each of the plurality of receiving grooves, on which the seating ledge is seated.

[0026] The above-mentioned mounting projection is mounted on the pocket cell mounting portion and can maintain a state in which each of the plurality of pocket cells is placed in each of the plurality of receiving grooves.

[0027] The sealing portion is positioned above the mounting ledge mounted on the pocket cell mounting portion, thereby restricting the mounting ledge from moving upward from the pocket cell mounting portion.

[0028] A body coupling groove facing the lower end of the sheet body may be formed on the upper side of the container body.

[0029] At the bottom of the above-mentioned sheet body, a sheet coupling projection that is inserted into the above-mentioned body coupling groove may be formed.

[0030] The above sheet body may be seated on the upper side of the sealing portion with the sheet coupling projection inserted into the body coupling groove, thereby restricting left and right movement relative to the container body.

[0031] A tray coupling groove may be formed on the outer perimeter of the lower tray.

[0032] A lid coupling projection that is inserted into the tray coupling groove may be formed on the lower outer perimeter of the lid portion.

[0033] The lid portion is coupled to the lower tray with the lid coupling projection inserted into the tray coupling groove, thereby restricting vertical deviation of the container body, the plurality of pocket cells, the sealing portion, and the sheet body.

[0034] The lid portion may include a lid upper surface portion covering the upper side of the sheet body and a plurality of sheet pressure protrusions protruding downward toward the sheet body from the inner surface of the lid upper surface portion.

[0035] The plurality of sheet pressure protrusions may be positioned in contact with or close to the upper surface of the sheet body to restrict the sheet body from being spaced upward from the container body.

[0036] The above sheet body can be maintained in a state where it is pressed against the upper side of the sealing portion by the plurality of sheet pressure protrusions, so that the sealing portion is maintained in a position that restricts the upper side detachment of each of the plurality of pocket cells. Effects of the invention

[0038] The strawberry vertical stacking packaging container according to the present invention can individually accommodate strawberries in a vertical direction such that the bottom part to which the stem of the strawberry is attached or the bottom part exposed after the stem is removed faces downward and the tip of the strawberry faces upward, thereby reducing the pressure applied to the sides of the strawberries compared to the conventional packaging method of stacking strawberries in a horizontal position.

[0039] In addition, the strawberry vertical stacking packaging container according to the present invention can support the strawberries so that the load of the strawberries is transferred to the lower direction of the strawberries rather than to the sides of the strawberries, thereby mitigating the side of the strawberries from being pressed or damaged by vibrations or shocks that occur during distribution and delivery.

[0040] In addition, since the strawberry vertical stacking packaging container according to the present invention allows each of the plurality of pocket cells to individually accommodate a strawberry, it is possible to reduce direct collisions between strawberries inside the packaging container or continuous compression of strawberries while they are in close contact with each other. Accordingly, it is possible to suppress the spread of damage to some strawberries to the deterioration of quality of surrounding strawberries.

[0041] In addition, the strawberry vertical stacking packaging container according to the present invention can accommodate strawberries such that at least 55% of the strawberries are located inside the pocket cells based on the total length of the strawberries in the height direction, thereby stably maintaining the vertical orientation of the strawberries compared to packaging methods that only support the bottom of the strawberries shallowly. Accordingly, the phenomenon of strawberries tilting or falling out of the pocket cells due to shaking during delivery can be reduced.

[0042] In addition, the strawberry vertical stacking packaging container according to the present invention can mitigate vibrations or shocks being directly transmitted to the surface of the strawberries during distribution, as the pocket cells are formed of a silicone-based film, a soft synthetic resin film, or an elastic polymer film and can be elastically deformed in response to the movement of the strawberries. Accordingly, surface compression, bruising, and damage to the flesh of the strawberries can be reduced.

[0043] In addition, the strawberry vertical stacking packaging container according to the present invention can stably maintain the stacked state of the lower tray, container body, pocket cell, sealing part, sheet body, and lid part, as the sealing part restricts the upward displacement of the pocket cell, the sheet body aligns the position of the strawberry, and the sheet pressure projection of the lid part restricts the sheet body from being separated upward from the container body.

[0044] In addition, the strawberry vertical stacking packaging container according to the present invention may have a lower tray and a lid portion formed of PET plastic, and the tray coupling groove of the lower tray and the lid coupling projection of the lid portion may be coupled in a snap-fit ​​manner at a corner portion or an outer coupling point, so the closed state of the packaging container can be stably maintained without separate fastening parts.

[0045] In addition, the strawberry vertical stacking packaging container according to the present invention can accommodate strawberries upright, taking into account the natural shape and actual consumption pattern of the strawberries, thereby improving both the stability of the raw material in the packaged state and the marketability visible to consumers.

[0046] In addition, the strawberry vertical stacking packaging container according to the present invention allows the strawberries to be maintained in an individually contained state even if some strawberries are damaged or moisture occurs, thereby reducing the phenomenon where moisture spreads to surrounding strawberries and leads to mold growth or a chain reaction of quality deterioration.

[0047] The effects of the present invention are not limited to those mentioned above and may include effects derived from the composition of the present invention, such as improved vertical stacking stability of strawberries, relief of lateral pressure, improved individual solubility, relief of shock during delivery, improved packaging closure stability, and improved strawberry quality retention.

[0071] Hereinafter, a strawberry vertical stacking packaging container according to one embodiment of the present invention will be described in detail.

[0073] Referring to FIGS. 1 to 7, the strawberry vertical stacking packaging container (10) according to one embodiment of the present invention is a packaging container for individually accommodating strawberries in a vertical direction such that the bottom part with the stem attached or the bottom part exposed after the stem is removed faces downward and the tip of the strawberry faces upward, without stacking the strawberries in the conventional horizontal state. The strawberry vertical stacking packaging container (10) according to one embodiment of the present invention can suppress damage to the sides of strawberries, moisture generation, and mold spread by reducing the phenomenon where the side of a strawberry is directly pressed against the side of another strawberry, the inner wall of the container, or the inner surface of the lid (600) when vibration or impact occurs during distribution, and by ensuring that the load of the strawberry is transferred to the bottom of the strawberry rather than the side of the strawberry.

[0074] A strawberry vertical stacking packaging container (10) according to one embodiment of the present invention may include a lower tray (100), a container body (200) seated on the lower tray (100) and having a plurality of receiving grooves (201) formed therein, a plurality of pocket cells (300) disposed in each of the plurality of receiving grooves (201), a sealing part (400) disposed on the upper side of the container body (200) and restricting the upper detachment of each of the plurality of pocket cells (300), a sheet body (500) seated on the upper side of the sealing part (400) and having a plurality of holes (501) formed therein corresponding to the plurality of receiving grooves (201), and a lid part (600) covering the upper side of the sheet body (500) and coupled to the lower tray (100). The lower tray (100), the container body (200), the plurality of pocket cells (300), the sealing part (400), the sheet body (500), and the lid part (600) can be arranged sequentially from the lower side to the upper side, and each component can be combined or stacked to mitigate shock during distribution while maintaining the vertical stacking state of the strawberries (S).

[0075] Meanwhile, the overall outer shape, corner shape, top surface shape, reinforcement shape, opening shape, arrangement shape of each receiving part, and detailed shape of the coupling structure of the lower tray (100), container body (200), plurality of pocket cells (300), sealing part (400), sheet body (500), and lid part (600) are not limited to the illustrated examples. The lower tray (100), container body (200), plurality of pocket cells (300), sealing part (400), sheet body (500), and lid part (600) may be formed in various planar shapes such as rectangular, rectangular, square, or equivalent shapes depending on the number, size, arrangement method, packaging specifications, transport conditions, product design, and manufacturing conditions of strawberries to be received, and the height, edge shape, rib shape, and arrangement structure of each component may also be varied during production. Therefore, the shape differences shown in FIGS. 1 and FIGS. 3 are merely examples to explain the technical features of the present invention, and the technical essence of the present invention lies in a strawberry vertical stacking packaging container that can stably accommodate strawberries upright and protect them from external impact.

[0076] Referring to Figure 1, if necessary, a band, label, or auxiliary cover for packaging for product indication may be additionally provided on the outer side of the strawberry vertical stacking packaging container (10).

[0077] The lower tray (100) is configured to form the lower outer edge of the strawberry vertical stacking packaging container (10). The lower tray (100) may include a tray bottom portion on which the container body (200) is seated, and a tray side wall portion extending upward from the outer perimeter of the tray bottom portion. The lower tray (100) may support the lower side of the container body (200) and provide a lower support standard to maintain a stable stacked state of the container body (200), a plurality of pocket cells (300), a sealing portion (400), and a sheet body (500) inside the packaging container.

[0078] The lower tray (100) may be formed from PET plastic. When the lower tray (100) is formed from PET plastic, the lower tray (100) can secure transparency, moldability, and a certain elastic recovery required for food packaging containers. The lower tray (100) is formed from transparent PET plastic so that the arrangement of the container body (200) and the strawberry (S) placed inside the lower tray (100) can be checked from the outside, and the connection part of the outer perimeter can be elastically deformed and restored during the connection process with the lid part (600). The lower tray (100) may be formed from transparent synthetic resin, translucent synthetic resin, or thermoformable resin permitted for food packaging in addition to PET plastic, but it may be preferable to form it from PET plastic considering the elastic fitting connection between the lower tray (100) and the lid part (600) and the verification of the packaging state.

[0079] The lower tray (100) may include a plurality of body support protrusions (110) that protrude upward toward the container body (200) from the upper surface of the bottom portion of the tray. The plurality of body support protrusions (110) may be arranged to support the bottom of the container body (200) or the outer lower side of the container body (200) when the container body (200) is seated on the lower tray (100). The plurality of body support protrusions (110) may reduce the container body (200) from sagging or tilting downward inside the lower tray (100) and allow the container body (200), a plurality of pocket cells (300), a sealing portion (400), and a sheet body (500) to be maintained at a constant height inside the lower tray (100).

[0080] Additionally, a plurality of main body support protrusions (110) may be spaced apart from each other and positioned facing the central area of ​​the bottom of the lower tray (100), the inner perimeter area of ​​the lower tray (100), or the outer lower side of the container body (200). When the plurality of main body support protrusions (110) are spaced apart from each other, the concentration of the load of the plurality of pocket cells (300) and strawberries (S) contained in the container body (200) at a specific location on the lower tray (100) can be reduced, and deformation of the bottom of the lower tray (100) can be suppressed.

[0081] The container body (200) is configured to be seated on the lower tray (100). The container body (200) may be positioned on the upper side of the tray bottom portion of the lower tray (100), and the outer edge of the container body (200) may be located on the inner side of the tray side wall portion of the lower tray (100). A plurality of receiving grooves (201) may be formed in the container body (200). Each of the plurality of receiving grooves (201) may provide a position where each of the plurality of pocket cells (300) is placed and may form a space where the lower portion of each of the plurality of pocket cells (300) is located. The plurality of receiving grooves (201) may be arranged spaced apart from each other along the length and width directions of the container body (200) so that strawberries (S) can be received independently in the vertical direction. Each of the plurality of receiving grooves (201) can be formed to support one pocket cell corresponding to one strawberry (S), and the spacing between the plurality of receiving grooves (201) can be set to a distance that reduces direct contact between the strawberries (S).

[0082] Each of the plurality of receiving grooves (201) may include a groove bottom portion facing the lower portion of the pocket cell and a groove side wall portion extending upward from the perimeter of the groove bottom portion. The groove bottom portion may be positioned to support the lower portion of the pocket cell, and the groove side wall portion may be positioned to limit the lateral movement range of the pocket cell. The groove side wall portion may be positioned at a predetermined distance from the outside of the pocket cell so that the pocket cell is not completely fixed inside the receiving groove, but can be slightly displaced together with the strawberry due to vibration or impact during distribution. Accordingly, the pocket cell can act as a cushioning component that absorbs the movement of the strawberry, and can reduce the phenomenon where the side of the strawberry is strongly pressed against the inner surface of the hole of the sheet body (500) or the inner surface of the lid portion (600).

[0083] Each of the plurality of pocket cells (300) is configured to be placed in each of the plurality of receiving grooves (201). Each of the plurality of pocket cells (300) can individually receive a strawberry in a vertical direction such that the lower part with the stem attached or the bottom part exposed after the stem has been removed faces downward and the tip of the strawberry faces upward. When the strawberry is packaged with the stem attached, the pocket cell can receive the lower part where the stem is located, and when the strawberry is packaged with the stem removed, the pocket cell can receive the lower part where the bottom part is located. Therefore, the pocket cell can be applied to both strawberries with the stem attached and strawberries with the stem removed, and can maintain the vertical stacking direction of the strawberry regardless of the pre-packaging processing state of the strawberry.

[0084] Each of the plurality of pocket cells (300) may have a concave cup shape that surrounds the lower outer and middle outer edges of the strawberry (S) in a circumferential direction. Each of the plurality of pocket cells (300) may include a lower receiving portion in which the lower part of the strawberry is received, and a lateral receiving portion that extends upward from the circumference of the lower receiving portion to support the lower outer and middle outer edges of the strawberry in a circumferential direction. The lower receiving portion may be formed as a curved surface or a gentle concave surface to support the lower part of the strawberry while reducing the concentrated compression of the lower part of the strawberry at a single point. The lateral receiving portion may surround the lower outer and middle outer edges of the strawberry in a circumferential direction to limit the strawberry from shaking excessively from side to side inside the receiving groove.

[0085] Each of the multiple pocket cells (300) can accommodate a strawberry such that at least 55% of the strawberry is located inside each pocket cell based on the total height-direction length from the bottom part where the stem of the strawberry (S) is attached or the bottom part where the stem is removed and exposed to the tip of the strawberry. The total height-direction length of the strawberry can be defined as the straight-line distance from the bottom point of the strawberry to the top point of the tip of the strawberry while the strawberry is accommodated vertically in the pocket cell. The fact that at least 55% of the strawberry is located inside the pocket cell means that the area from the bottom point of the strawberry to a position corresponding to at least 55% of the total height-direction length of the strawberry is surrounded by the internal accommodating space of the pocket cell or is located below the top of the pocket cell. Accordingly, unlike a structure that only shallowly supports the bottom of the strawberry, the pocket cell sufficiently surrounds the middle outer edge of the strawberry, thereby reducing the likelihood of the strawberry easily tilting or falling out of the pocket cell during distribution.

[0086] Each of the multiple pocket cells (300) can support the strawberry so that the load of the strawberry is transferred to the bottom of the strawberry rather than to the side of the strawberry (S). Specifically, when the strawberry is accommodated in the pocket cells in a vertical direction, the weight of the strawberry can be mainly transferred to the bottom where the stem is attached or the base is located, rather than to the side of the strawberry. Therefore, the phenomenon of the side of the strawberry being pressed by the inner side of the packaging container or the side of another strawberry can be reduced, and the occurrence of bruises, indentations, or moisture on the side surface of the strawberry can be reduced. In particular, since the side of the strawberry is a part where the flesh tissue is vulnerable to external impact, the support direction of the pocket cells that reduces pressure concentrated on the side of the strawberry can be advantageous for maintaining distribution quality.

[0087] Each of the plurality of pocket cells (300) can mitigate the shock transmitted to the strawberry by being displaced together with the strawberry relative to the container body (200) when vibration or shock occurs during distribution. The displacement may include vertical displacement, horizontal displacement, or tilting displacement occurring within the receiving groove of the container body (200). Since each of the plurality of pocket cells (300) can move together with the strawberry while holding the strawberry inside the pocket cell, the relative friction between the surface of the strawberry and the inner surface of the pocket cell can be reduced compared to the case where only the strawberry shakes independently inside the pocket cell. Additionally, as the pocket cells are displaced together with the strawberry, they can disperse external vibration energy into elastic deformation and positional displacement of the pocket cells.

[0088] Each of the plurality of pocket cells (300) may be formed from any one of a silicone-based film, a soft synthetic resin film, or an elastic polymer film. A silicone-based film may provide the characteristic of returning to its original shape even after repeated elastic deformation. A soft synthetic resin film may be formed from a resin material suitable for food packaging and may deform in response to the movement of the strawberry while maintaining the cup shape of the pocket cell. An elastic polymer film may gently wrap the lower outer and middle outer edges of the strawberry and disperse the contact pressure transmitted to the surface of the strawberry (S). Each of the plurality of pocket cells (300) may be elastically deformed in response to the movement of the strawberry, and through elastic deformation, the direct transmission of vibration or shock to the surface of the strawberry during distribution may be reduced.

[0089] Each of the plurality of pocket cells (300) may include a settling ridge (310) that protrudes outward from the upper circumference of each pocket cell. The settling ridge (310) may be formed continuously along the upper circumference of the pocket cell, or it may be formed in a divided manner along a portion of the upper circumference of the pocket cell. The settling ridge (310) may function as a locking configuration that restricts the pocket cell from descending excessively into the receiving groove and ensures that the pocket cell is positioned at a predetermined height relative to the container body (200). The settling ridge (310) may protrude outward from the upper side of the pocket cell and be placed on the pocket cell settling portion (210) of the container body (200).

[0090] In the container body (200), a pocket cell seating portion (210) may be formed along the outer circumference of each of the plurality of receiving grooves (201), on which a seating ledge (310) is seated. The pocket cell seating portion (210) may be provided as a stepped surface, a flat surface, an annular support surface, or a circumferential support surface formed on the upper circumference of the receiving groove. The seating ledge (310) may be seated on the pocket cell seating portion (210) to maintain the state in which the pocket cell is placed in the receiving groove. The pocket cell seating portion (210) supports the seating ledge (310) from below, and a sealing portion (400) may be positioned above the seating ledge (310) to restrict upward displacement of the seating ledge (310). Accordingly, the seating ledge (310) is positioned between the pocket cell seating portion (210) and the sealing portion (400), and the pocket cell can be elastically deformed in response to the movement of the strawberry (S) without falling upward inside the receiving groove.

[0091] Furthermore, each of the plurality of pocket cells (300) may include a seating ledge (310) that protrudes outward from the upper circumference of the pocket cell. A locking groove may be formed on the lower side of the seating ledge (310) into which the pocket cell seating portion (210) of the container body (200) is inserted. The pocket cell seating portion (210) is formed along the outer circumference of each of the plurality of receiving grooves (201), and the seating ledge (310) may be seated on the pocket cell seating portion (210). At this time, the locking groove is formed to accommodate at least a portion of the pocket cell seating portion (210) so as to restrict the pocket cell from easily detaching upward from the receiving groove.

[0092] Additionally, the locking groove may be provided not as a configuration to completely fix the pocket cell to the container body (200), but as a configuration that allows the pocket cell to elastically deform in response to the movement of the strawberry (S) while maintaining the state in which the pocket cell is seated in the pocket cell seating portion (210). Accordingly, when vibration or shock occurs during distribution, the pocket cell does not detach from the receiving groove, but moves together with the strawberry or elastically deforms to mitigate the shock transmitted to the strawberry.

[0093] The sealing portion (400) is configured to be positioned on the upper side of the container body (200). The sealing portion (400) can restrict the upward displacement of each of the plurality of pocket cells (300). The sealing portion (400) can be positioned on the upper side of the mounting ledge (310) mounted on the pocket cell mounting portion (210), and can restrict the mounting ledge (310) from moving upward from the pocket cell mounting portion (210). The sealing portion (400) can be located between the lower side of the sheet body (500) and the upper side of the container body (200), and can function as an intermediate fixing layer that presses the upper perimeter of the pocket cells mounted on the container body (200). The sealing portion (400) does not strongly fix the entire pocket cell, but rather restricts the upward displacement of the pocket cell while maintaining a state in which the pocket cell can elastically deform in response to the movement of the strawberry (S).

[0094] The sealing portion (400) may include a plurality of through openings or a plurality of incisions corresponding to the location of each of the plurality of pocket cells (300). The plurality of through openings or a plurality of incisions may be formed so that the upper part of the strawberry (S) is exposed upward or positioned toward the hole of the sheet body (500) while the strawberry is contained in the pocket cell. The sealing portion (400) may be formed by distinguishing between a portion covering the upper side of the seating ledge (310) of the pocket cell and a portion through which the strawberry passes or is exposed. Accordingly, the sealing portion (400) can restrict the upward displacement of the pocket cell without interfering with the vertical arrangement of the strawberry.

[0095] The sheet body (500) is configured to be seated on the upper side of the sealing portion (400). A plurality of holes (501) corresponding to a plurality of receiving grooves (201) may be formed in the sheet body (500). Each of the plurality of holes (501) may be formed at a position corresponding in the vertical direction to each of the plurality of receiving grooves (201) and each of the plurality of pocket cells (300). Each of the plurality of holes (501) may be formed to allow a part of the strawberry to pass through while the tip of the strawberry faces upward, or to restrict the outer position of the strawberry in the circumferential direction. The sheet body (500) can align the position of the strawberries when they are stacked in the vertical direction, reduce direct contact between adjacent strawberries, and maintain a constant arrangement of strawberries inside the packaging container.

[0096] Each of the plurality of holes (501) may be formed in a circular, elliptical, or gentle curved shape corresponding to the outer edge of the strawberry (S). The inner surface of each of the plurality of holes (501) may be formed to be larger than the maximum width of the strawberry or to be sized to limit the position of the outer edge of the middle part of the strawberry so as not to be excessively compressed against the outer surface of the strawberry. Each of the plurality of holes (501) may function not as a structure that permanently clamps the strawberry, but as a structure that provides a vertical arrangement standard for the strawberry and limits excessive lateral movement of the strawberry. Accordingly, the strawberry is supported at the bottom by the pocket cell, its position is aligned by the holes of the sheet body (500), and upward deviation is limited by the lid part (600).

[0097] On the upper side of the container body (200), a body coupling groove (220) facing the lower side of the sheet body (500) may be formed. On the lower side of the sheet body (500), a sheet coupling projection (510) that is inserted into the body coupling groove (220) may be formed. The sheet coupling projection (510) may protrude downward from the lower surface of the sheet body (500), and the body coupling groove (220) may be formed in a groove shape that can accommodate the sheet coupling projection (510) on the upper side of the container body (200). The sheet body (500) may be seated on the upper side of the sealing portion (400) with the sheet coupling projection (510) inserted into the body coupling groove (220), and the left and right movement of the sheet body (500) relative to the container body (200) may be restricted due to the coupling of the sheet coupling projection (510) and the body coupling groove (220). The coupling relationship between the main body coupling groove (220) and the sheet coupling projection (510) can reduce the misalignment of the plurality of holes (501) of the sheet main body (500) and the plurality of receiving grooves (201) of the container main body (200) in the vertical direction.

[0098] The lid portion (600) is configured to cover the upper side of the sheet body (500). The lid portion (600) can be coupled to the lower tray (100) and, together with the lower tray (100), can form an external closed state of the packaging container. The lid portion (600) can be formed of PET plastic. When the lid portion (600) is formed of PET plastic, the lid portion (600) protects the strawberry (S) from external impact while covering the upper side of the sheet body (500), and can provide shape retention so that a plurality of sheet pressure protrusions (630) formed on the inner surface of the lid portion (600) can press the sheet body (500) downward. The lid portion (600) can be formed of transparent PET plastic, and when formed of transparent PET plastic, the arrangement of strawberries inside the packaging container and the quality of the strawberries can be checked from the outside.

[0099] A tray coupling groove (101) may be formed on the outer perimeter of the lower tray (100). The tray coupling groove (101) is not limited to a groove formed continuously along the entire outer perimeter of the lower tray (100), but may be formed locally at each corner of the lower tray (100) or at a selected coupling location among the outer perimeter of the lower tray (100). That is, the tray coupling groove (101) may be a concave coupling portion formed at a corner of the outer perimeter of the lower tray (100) where locking coupling with the lid portion (600) is required. The tray coupling groove (101) may be provided as a groove into which a lid coupling projection (610) formed on the lower outer perimeter of the lid portion (600) can be elastically inserted.

[0100] A lid coupling projection (610) that is inserted into a tray coupling groove (101) may be formed on the lower outer circumference of the lid portion (600). The lid coupling projection (610) is not limited to a projection formed continuously along the entire lower outer circumference of the lid portion (600), but may be formed locally at a corner portion or an outer coupling point corresponding to the tray coupling groove (101) of the lower tray (100). The lid coupling projection (610) may be provided as a projection portion that protrudes toward the tray coupling groove (101) of the lower tray (100) from the lower outer circumference of the lid portion (600). The lid coupling projection (610) can be elastically inserted into the tray coupling groove (101) during the process in which the lid portion (600) covers the upper side of the lower tray (100), and after insertion, it is engaged with the inner surface of the tray coupling groove (101) to restrict the lid portion (600) from being easily separated from the lower tray (100).

[0101] The tray coupling groove (101) and the lid coupling projection (610) can form a snap-type coupling structure that interlocks with each other at the corner or outer coupling point of the lower tray (100) and the lid portion (600). Here, the snap-type coupling structure does not refer to a separate metal snap button or a separate fastening part, but rather to a structure in which parts of the lower tray (100) and the lid portion (600), formed of PET plastic, are elastically deformed to interlock with each other, and after interlocking, a locked state is maintained. When a user presses the lid portion (600) toward the lower tray (100), the lid coupling projection (610) can be inserted into the tray coupling groove (101) by the elastic deformation of the PET plastic, and after insertion, the lid coupling projection (610) catches on the inner surface of the tray coupling groove (101), thereby maintaining the state in which the lid portion (600) is coupled to the lower tray (100).

[0102] Since the tray coupling groove (101) and the lid coupling projection (610) can be positioned at the corners of the lower tray (100) and the lid portion (600), the closed state of the packaging container can be stably maintained without strongly compressing the entire outer perimeter of the lower tray (100) and the lid portion (600). Additionally, when the tray coupling groove (101) and the lid coupling projection (610) are positioned at multiple corners, the lid portion (600) may be restricted from shifting in the left-right direction relative to the lower tray (100), and the vertical displacement of the container body (200), multiple pocket cells (300), sealing portion (400), and sheet body (500) positioned between the lower tray (100) and the lid portion (600) may also be restricted. Therefore, the tray coupling groove (101) and the lid coupling projection (610) can simultaneously perform the external closing function of the packaging container and the function of preventing the internal stacking configuration from dislodging.

[0103] The lid portion (600) may include a lid upper surface portion (620) covering the upper side of the sheet body (500), and a plurality of sheet pressure protrusions (630) protruding downward toward the sheet body (500) from the inner surface of the lid upper surface portion (620). The plurality of sheet pressure protrusions (630) may protrude downward from the inner surface of the lid upper surface portion (620) to contact the upper surface of the sheet body (500) or be positioned in close proximity to the upper surface of the sheet body (500). The plurality of sheet pressure protrusions (630) may limit the sheet body (500) from being spaced upward from the container body (200). When the plurality of sheet pressure protrusions (630) contact the upper surface of the sheet body (500), the sheet body (500) may be maintained in a state of being directly pressured on the upper side of the sealing portion (400). When a plurality of sheet pressure protrusions (630) are positioned close to the upper surface of the sheet body (500), the displacement of the sheet body (500) rising upward due to vibration during circulation can be limited within a certain range.

[0104] The sheet body (500) can be maintained in a state where it is pressed against the upper side of the sealing part (400) by a plurality of sheet pressure protrusions (630). In this case, the sealing part (400) can be stably maintained in a position that restricts the upper detachment of each of the plurality of pocket cells (300). That is, the sheet pressure protrusions of the lid part (600) are not merely reinforcing protrusions that increase the rigidity of the lid part (600), but can function as a configuration that supports or presses the sheet body (500) downward to maintain the position of the sheet body (500) and the sealing part (400). Accordingly, the detachment of the pocket cell's seating ledge (310) between the pocket cell seating part (210) and the sealing part (400) is restricted, and the pocket cell can be deformed in response to the movement of the strawberry (S) without falling out upward while containing the strawberry.

[0105] A plurality of sheet pressure protrusions (630) may be positioned at a location corresponding to at least one of the area between the plurality of holes (501) of the sheet body (500), the outer area of ​​the sheet body (500), or the central area of ​​the sheet body (500). If the plurality of sheet pressure protrusions (630) are positioned so as not to directly interfere with the plurality of holes (501), direct contact between the sheet pressure protrusions and the strawberry can be reduced even when the tip of the strawberry (S) is positioned upward. The plurality of sheet pressure protrusions (630) may be positioned spaced apart from each other on the inner surface of the lid upper surface (620) so as to press the sheet body (500) uniformly over the entire surface. Accordingly, the phenomenon of only a part of the sheet body (500) lifting upward is reduced, and the pocket cell detachment restriction function by the sealing part (400) can be stably maintained.

[0106] In a strawberry vertical stacking packaging container (10) according to one embodiment of the present invention, during the process of accommodating strawberries (S) in pocket cells, the container body (200) is first placed on the lower tray (100), and a plurality of pocket cells (300) are arranged in each of the plurality of receiving grooves (201) of the container body (200), and then strawberries (S) can be inserted vertically into each of the plurality of pocket cells (300). The strawberries may be arranged such that the lower part with the stem attached or the bottom part exposed after the stem is removed faces the lower receiving part of the pocket cell, and the tip of the strawberry faces upward. Subsequently, a sealing part (400) is placed on the upper side of the container body (200) to cover the upper side of the seating ledge (310) of the pocket cell, and a sheet body (500) is placed on the upper side of the sealing part (400) to align the position of the strawberries through a plurality of holes (501). Finally, the lid portion (600) covers the upper side of the sheet body (500) and is coupled to the lower tray (100), thereby forming a closed state of the packaging container.

[0107] In the process of the lid portion (600) being coupled to the lower tray (100), the lid coupling projection (610) formed at the corner portion or outer coupling point of the lower outer circumference of the lid portion (600) can be inserted into the tray coupling groove (101) formed at the corresponding corner portion or outer coupling point of the outer circumference of the lower tray (100). The lid coupling projection (610) can enter the tray coupling groove (101) while being temporarily elastically deformed during the process of the lid portion (600) being pressed toward the lower tray (100), and after being inserted into the tray coupling groove (101), it can be caught on the inner surface of the tray coupling groove (101) by means of elastic restoring force. Accordingly, the lid portion (600) can be fastened to the lower tray (100) in a snap-fast manner, and the likelihood of the lid portion (600) easily separating from the lower tray (100) can be reduced even if the packaging container is shaken during distribution.

[0108] When vibration or impact is transmitted to the packaging container during distribution, the strawberry (S) may be shaken while being received vertically inside the pocket cell. At this time, the pocket cell can be elastically deformed in response to the movement of the strawberry while encircling the lower outer and middle outer edges of the strawberry, and can be slightly displaced relative to the container body (200) together with the strawberry inside the receiving groove. Accordingly, the phenomenon of the strawberry shaking independently and repeatedly colliding with the inner surface of the pocket cell, the inner surface of the hole of the sheet body (500), or the inner surface of the lid (600) can be reduced. Additionally, since the load of the strawberry is transmitted downward through the pocket cell, the phenomenon of the side of the strawberry being compressed and damaged can be reduced.

[0109] According to one embodiment of the present invention, the strawberry vertical stacking packaging container (10) accommodates strawberries (S) such that at least 55% of the total height length of the strawberries is located inside the pocket cell, thereby allowing the vertical orientation of the strawberries to be maintained more stably than when the pocket cell only shallowly supports the lower part of the strawberries. Additionally, the sealing portion (400) restricts the upward displacement of the pocket cell, the sheet body (500) aligns the position of the strawberries, and the sheet pressure projection of the lid portion (600) restricts the sheet body (500) from being separated upward from the container body (200). Furthermore, the lower tray (100) and the lid portion (600) may be formed of PET plastic, and the tray coupling groove (101) of the lower tray (100) and the lid coupling projection (610) of the lid portion (600) may be coupled in a snap-on manner at the corner portion or outer coupling point, thereby allowing the closed state and internal stacking state of the packaging container to be maintained stably. Therefore, the lower tray (100), container body (200), pocket cell, sealing part (400), sheet body (500), and lid part (600) interact to maintain the vertical stacking state of the strawberries and reduce damage to the strawberries caused by vibration and shock during distribution.

[0111] Meanwhile, in a strawberry vertical loading packaging container (10) according to another embodiment, a cushioning lip may be formed on the inner circumference of each of the plurality of holes (501) of the sheet body (500). The cushioning lip may be formed to protrude from the inner circumference of the hole of the sheet body (500) toward the center of the hole, and may be positioned in contact with or close to the middle outer edge of the strawberry. The cushioning lip may be provided as an elastic support configuration to reduce the direct collision or direct compression of the middle outer edge of the strawberry (S) against the inner circumference of the hole of the sheet body (500) while the strawberry is received vertically in the pocket cell.

[0112] The cushioning lip may be formed as a continuous annular protrusion along the inner circumference of each of the plurality of holes (501). Alternatively, the cushioning lip may be formed as a plurality of spaced-apart segmented lip along the inner circumference of each of the plurality of holes (501). When the cushioning lip is formed as a plurality of segmented lip, the plurality of segmented lip may be spaced apart from each other along the circumference direction with respect to the center of the hole and may partially support different locations among the middle outer edges of the strawberry (S). Accordingly, the contact pressure may be dispersed through the elastic deformation of the cushioning lip rather than the entire surface of the strawberry being widely compressed against the inner circumference of the hole of the sheet body (500).

[0113] The cushioning lip may be formed integrally with the sheet body (500). For example, if the sheet body (500) is formed of a soft synthetic resin or a thermoformed resin, the cushioning lip may be formed by molding a portion of the inner surface of the hole of the sheet body (500) so that it protrudes toward the center of the hole. Alternatively, the cushioning lip may be formed as a separate soft ring member from the sheet body (500) and then coupled to the inner surface of each of the plurality of holes (501). However, considering the simplification of the manufacturing process and the hygiene of the food packaging container, it may be preferable for the cushioning lip to be formed integrally with the sheet body (500).

[0114] The cushioning lip can be elastically deformed in response to the movement of the strawberry. When vibration or impact occurs during distribution, the strawberry (S) can be displaced relative to the container body (200) along with the pocket cell, and the middle outer edge of the strawberry can move toward the inner surface of the hole of the sheet body (500). At this time, the cushioning lip can first come into contact with the middle outer edge of the strawberry to prevent the middle outer edge of the strawberry from directly hitting the inner surface of the hole of the sheet body (500). Additionally, the cushioning lip is elastically deformed while being pressed by the middle outer edge of the strawberry, and can absorb or disperse impact energy transmitted to the surface of the strawberry through elastic deformation.

[0115] The cushioning lip may include an inclined support surface that protrudes toward the center of the hole as it moves from the upper side to the lower side with respect to the thickness direction of the sheet body (500). Alternatively, the cushioning lip may include an inclined support surface that protrudes toward the center of the hole as it moves from the lower side to the upper side with respect to the thickness direction of the sheet body (500). If the cushioning lip includes an inclined support surface, the outer edge of the strawberry may be reduced from being caught on the cushioning lip and excessively damaged during the process of inserting the strawberry into the pocket cell in the vertical direction, and after insertion of the strawberry, the cushioning lip can gently support the middle outer edge of the strawberry (S).

[0116] The cushioning lip may be provided in a configuration that does not strongly fix the maximum width portion of the strawberry, but rather mitigates the direct compression of the middle outer edge of the strawberry against the inner surface of the hole. Accordingly, the protrusion length of the cushioning lip may be set to a range that limits lateral shaking of the strawberry without interfering with the longitudinal receiving state of the strawberry (S). For example, the protrusion length of the cushioning lip may be formed in a range of 0.5 mm to 5 mm from the inner surface of the hole toward the center of the hole. This range may be adjusted considering the size variation of the strawberry and the molding error of the packaging container.

[0117] In this way, when a cushioning lip is formed on the inner surface of the hole of the sheet body (500), the lower part of the strawberry is supported by the pocket cell, and the middle outer part of the strawberry (S) can be elastically supported by the cushioning lip. Accordingly, since the lower and middle parts are each cushioned and supported while the strawberry is received in the vertical direction, the phenomenon of the side of the strawberry directly colliding with or being compressed against the inner surface of the hole of the sheet body (500) due to vibration or impact during distribution can be reduced.

[0119] In a strawberry vertical stacking packaging container (10) according to another embodiment, a moisture separation groove may be formed in the lower receiving portion of each of the plurality of pocket cells (300). The moisture separation groove may be provided as a groove to separate moisture generated or flowing between the lower portion of the strawberry (S) and the lower receiving portion of the pocket cell from the lower contact position of the strawberry. The moisture separation groove can reduce the direct contact of the lower portion of the strawberry with the stem attached or the exposed base portion with the stem removed with the stem removed from the lower receiving portion of the pocket cell for a long time, and can suppress moisture accumulating in the lower portion of the strawberry, thereby preventing the surface of the strawberry from easily becoming soft or developing mold.

[0120] A moisture separation groove may be formed in the central part of the lower receiving portion of the pocket cell. In this case, the moisture separation groove may be positioned facing the central contact location of the lower part of the strawberry, thereby reducing the accumulation of moisture generated from the lower part of the strawberry or residual moisture after washing thinly between the lower receiving portion of the pocket cell and the lower part of the strawberry. Alternatively, the moisture separation groove may be formed as a radial groove extending perimeterly from the central part of the lower receiving portion of the pocket cell. In this case, moisture may move from the central part of the lower part of the strawberry toward the outer side of the lower receiving portion of the pocket cell.

[0121] The moisture separation groove may include a single annular groove formed in the lower receiving portion of the pocket cell. The annular groove may be formed along the outer circumference of the position where the lower part of the strawberry rests in the lower receiving portion of the pocket cell, and may reduce the spreading of moisture across the entire contact surface between the lower part of the strawberry (S) and the lower receiving portion of the pocket cell. Additionally, the moisture separation groove may be formed as a plurality of intersecting straight grooves or curved grooves. The plurality of straight grooves or curved grooves may guide the moisture to be dispersed within the lower receiving portion of the pocket cell without concentrating at any one point.

[0122] The moisture separation groove may be formed as a non-penetrating groove that does not penetrate the lower receiving portion of the pocket cell. If the moisture separation groove is formed as a non-penetrating groove, moisture can be temporarily contained within the groove spaced apart from the lower contact position of the strawberry inside the pocket cell, thereby reducing the direct leakage of moisture to the lower side of the pocket cell. Alternatively, the moisture separation groove may be connected to a fine drainage hole that penetrates the lower receiving portion of the pocket cell. In this case, moisture inside the pocket cell can move toward the receiving groove of the container body (200) through the fine drainage hole.

[0123] A moisture collection groove may be formed at the bottom portion of each of the plurality of receiving grooves (201) of the container body (200). The moisture collection groove may be provided as a groove that collects moisture that has moved through a fine drainage hole formed in the lower receiving portion of the pocket cell or through the lower outer edge of the pocket cell at the bottom portion of the receiving groove. The moisture collection groove may be formed at a position facing the lower portion of the pocket cell, thereby reducing the direct contact between the lower portion of the pocket cell and the bottom portion of the receiving groove, while simultaneously collecting moisture that has moved to the lower portion of the pocket cell at a location away from the strawberry's lower contact position.

[0124] The moisture collection groove may be a concave groove formed in the center of the bottom portion of the receiving groove. Alternatively, the moisture collection groove may include a drainage guiding groove extending from the bottom portion of the receiving groove toward the side wall portion of the groove. The drainage guiding groove can guide moisture discharged from the lower side of the pocket cell toward the edge of the receiving groove and reduce the retention of moisture in the center of the lower side of the pocket cell where the load of the strawberry (S) is transmitted. Accordingly, prolonged contact between the lower part of the strawberry and moisture can be reduced.

[0125] The moisture separation groove and the moisture collection groove may be formed together. For example, a moisture separation groove and a fine drainage hole may be formed in the lower receiving portion of the pocket cell, and a moisture collection groove corresponding to the fine drainage hole in the vertical direction may be formed in the bottom portion of the receiving groove of the container body (200). In this case, moisture generated around the lower part of the strawberry may move along the moisture separation groove of the pocket cell and then move to the moisture collection groove of the receiving groove through the fine drainage hole. Therefore, the moisture may not remain for a long time between the lower contact position of the strawberry and the lower receiving portion of the pocket cell, but may be separated toward the bottom portion of the receiving groove.

[0126] The moisture separation groove can be formed so as not to interfere with the support function of the pocket cell that supports the lower part of the strawberry. That is, the moisture separation groove can be provided not as a groove that deeply cuts the entire lower receiving portion of the pocket cell, but as a shallow groove formed between the support surfaces while leaving a support surface that supports the load of the strawberry. Accordingly, the pocket cell can stably transmit the load of the strawberry (S) in the downward direction while reducing the accumulation of moisture at the lower contact location of the strawberry.

[0127] In addition, the moisture separation groove can work in conjunction with the elastic deformation function of the pocket cell. When vibration or shock occurs during distribution, the pocket cell can be displaced or elastically deformed along with the strawberry (S), and during this process, moisture remaining in the lower receiving portion of the pocket cell can move along the moisture separation groove. Therefore, the repeated deformation of the pocket cell can assist in the action of separating moisture from the lower contact position of the strawberry.

[0128] In this way, if a moisture separation groove is formed in the lower receiving portion of the pocket cell, or if a moisture collection groove is formed in the bottom portion of the receiving groove of the container body (200), the phenomenon of moisture accumulating between the lower portion of the strawberry (S) and the pocket cell can be reduced. Accordingly, the phenomenon of moisture generated from some strawberries during distribution coming into contact with the lower portion of the strawberry for a long time or spreading to surrounding strawberries can be suppressed, and the possibility of quality degradation and mold growth of the strawberries can be reduced.

[0130] The above description is merely an illustrative explanation of the technical concept of the present embodiment, and a person skilled in the art to which the present embodiment belongs would be able to make various modifications and variations within the scope of the essential characteristics of the present embodiment.
