Description

  The present invention relates to a fruit packaging container for packaging mainly fruits such as strawberries, strawberries, and flowerless fruits one by one.

  Conventionally, as a packaging container for relatively large-sized strawberries used for fruits such as strawberries, especially for progress, etc., the surface of the strawberries is relatively soft, and it is easy to cause damage from the part that is in contact with other things. A first container for buffer molded from a flexible foamed resin sheet having elasticity, and a second container for support molded from a synthetic resin sheet having shape retention so that the container can be supported There is known a fruit wrapping container that combines the above.

  For example, in Patent Document 1 (Japanese Utility Model Publication No. 61-144070) and Patent Document 2 (Japanese Utility Model Publication No. 62-3465), a plurality of storage recesses that can store fruits such as persimmons in an individual packaging state are formed. Shock absorbing combination of a shock-absorbing container made of a flexible foamed resin sheet and a supporting container made of a non-foamed synthetic resin sheet in which a holding recess for fitting and supporting the storage recess is formed Sex containers have been proposed. In the case of Patent Document 2, a supporting body made of a non-foamed synthetic resin sheet is integrally provided with a lid that covers the top of the fruit.

  In any of the proposed containers, the storage recess of the buffer container made of a flexible foamed resin sheet is fitted to the holding recess of the support container and supported in a suspended state. The supporting container is made of a relatively hard non-foamed synthetic resin sheet, and a buffering effect can hardly be expected. Therefore, the storage recess of the buffering container is fitted into the holding recess. When the peripheral side surfaces are in contact with each other, the elasticity of the flexible foamed resin sheet will be suppressed, and depending on the type of fruit such as straw stored in the storage recess, the buffering effect may be impaired. is there. In addition, the elastic recesses and bulge deformation of the storage recesses of the flexible foam sheet are regulated by fitting the storage recesses of the buffer containers and the holding recesses of the support containers over the entire circumference. Therefore, it may not be possible to cope with variations in the shape and size of the fruit to be stored.

Further, since the supporting container is configured to fit and support each storage recess in the buffer container with a corresponding holding recess, the buffer container and the support container are If the number of assorted fruits changes, it is necessary to prepare both the first container and the second container according to the number, and this kind of packaging This contributes to the high cost of the container.
Japanese Utility Model Publication No. 61-144070 Japanese Utility Model Publication No. 62-3465

  Accordingly, the present inventors have devised the structure of the support container in a fruit packaging container composed of a combination of a buffer container that can individually package fruits one by one and a support container that receives the fruit, and a storage recess of the buffer container. Protruding support portions that receive the portions of the non-recessed portions between the rows are partially provided so that they are received and supported without restraining the elastic bulging deformation and elasticity of the storage concave portions of the buffer containers. However, in this case, by providing the protruding support part partially, in a state where both the containers are combined and the buffer container is received and supported by the protruding support part of the support container, the upper buffer container is It is easy to move in the direction along the storage recess row, and in particular, the shallower the storage recess is, the easier it is to move, and the misalignment occurs and the support state becomes unstable, which may impair the protective effect of the stored fruits.

  The present invention also solves the above-described problems, and for a fruit packaging having a structure capable of maintaining a stable support state without fear of displacement movement in the direction of the storage concave portion of the buffer container combined on the support container In addition to providing a container, it is possible to selectively use at least two types of buffer containers having different numbers of storage recesses with respect to one type of support container while securing the above support structure. Thus, a fruit packaging container that can contribute to a reduction in fruit packaging cost is provided.

The present invention for solving the above-mentioned problems is a buffer container formed from a flexible foamed resin sheet having elasticity, and formed with a plurality of rows of storage recesses capable of storing fruits one by one, and the buffer container A fruit packaging container formed from a synthetic resin sheet having shape retention as compared to a tray-shaped support container for receiving and supporting the buffer container, wherein the support container is a peripheral edge of the buffer container. And a protruding support portion for supporting a portion between the storage recess rows at an inner portion corresponding to the space between the storage recess rows of the buffer container. Are formed at a plurality of locations at intervals in the direction along the storage recess row, and a top portion for receiving a non-recessed portion between the storage recess rows or a part of the vicinity thereof is formed. At least one summit There are horizontally formed with respect to a direction along the housing concave portion rows, and characterized by being provided so as to be restricted to movement along the housing concave portion rows of the buffering container in the support state by said top To do.

  According to this fruit packaging container, in use, a buffer container made of a flexible foamed resin sheet that accommodates fruits in an individual packaging state is supported by a support container made of a synthetic resin sheet having shape retention. That is, the buffer container has a peripheral edge supported by the side wall of the support container, and a protrusion provided in the support container at a non-recessed portion other than the storage recess in the inward portion or at a plurality of locations in the vicinity thereof. Supported by a plurality of tops of the support.

  In such a support state, the protruding support portion only contacts the outer surface of the storage recess between the storage recess rows of the buffer container, and the protrusion support portion suppresses the elasticity of the storage recess. Further, there is no restriction on swelling and displacement utilizing the elasticity of the material, particularly elastic displacement in the direction along the storage recess rows, and a good buffering effect against vibration and impact during transportation can be exhibited. Moreover, it can respond to the variation in the magnitude | size and shape of the fruit accommodated by the flexible elasticity of an accommodation recessed part.

In addition, since at least one top of the plurality of tops of the projecting support part of the support container is formed horizontally long in the direction along the storage recess row , this horizontally long top is the non-shock of the buffer container. In a state where it is in contact with and supported at a part of the recessed part, it is locked in a direction along the storage recessed part row with respect to a part other than the non-recessed part, along the storage recessed part row of the buffer container. The movement in the direction can be restricted, and the buffer container can be stably held at a predetermined position.

  In the fruit packaging container, the protruding support portion of the support container is continuously formed in a direction along the storage recess row corresponding to a portion between the storage recess rows of the buffer container, and the protruding support portion A top portion for receiving a non-recessed portion between the storage recess rows or a portion in the vicinity thereof may be formed at a plurality of locations at intervals in the longitudinal direction. Thereby, the movement of the buffer container in the direction intersecting with the protruding support portion can be restricted by the protruding support portion, and the buffer container can be supported more stably.

  The buffer container has a plurality of storage recesses arranged in three vertical rows, and has a non-recessed portion between the storage recess rows, and a part of the non-recessed portion corresponds to the top of the protruding support portion. It is a container in which each storage recess is arranged and formed so as to be positioned, and at least two kinds of containers having different numbers of storage recesses can be selectively combined with the support container. You can also. In this case, since one kind of the support container can be used in common for different numbers of fruit assortments, the number of types of support container molding can be reduced, the molding cost of the support container can be reduced, and buffering It can contribute to the cost reduction of the fruit packaging container by the container and the support container.

In addition, the present invention provides a buffer container formed of a flexible foamed resin sheet having elasticity, and formed with a plurality of rows of storage recesses that can store fruits one by one, as compared with the buffer container. A fruit packaging container formed from a synthetic resin sheet having a shape and comprising a tray-shaped support container for receiving and supporting the buffer container, wherein the support container is a side wall that receives a peripheral portion of the buffer container. together with a part, said projecting support portion for supporting the portion between the housing recess column at a location of the inner portion corresponding to between the housing concave portion rows of the buffering container is formed becomes, the said projecting support portion, said housing at a plurality of positions at intervals in a direction along the concave portion rows, the housing concave portion rows top portion for receiving a portion location of the non-recessed portion or the vicinity thereof is formed between Rutotomoni, the said top arcuate rounded attached It is characterized by being That. Thereby, it can be received and received without a problem in the position which the said top part shifted | deviated with respect to the said non-recessed part .

FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3 and FIG. 5 is a cross-sectional view taken along line V-V in FIG. 3. 6 is a cross-sectional view taken along the line VI-VI of FIG. 3, FIG. 7 is a perspective view of 15 buffer containers, and FIG. 8 is a part of the buffer container stacked on a support container. FIG. 9 is a sectional view taken along the line IX-IX in FIG.

  The fruit packaging container A of the present invention is formed from a flexible foamed resin sheet having elasticity by molding means such as vacuum molding, and a plurality of storage recesses 11 that can store fruits B to be packaged one by one in a packaged state. Is formed by a molding means such as vacuum molding from a buffer resin container 10 formed in a plurality of rows and a synthetic resin sheet having a shape-retaining property as compared with the buffer container 10, and the buffer container 10 has an outer shape. It comprises a tray-shaped support container 20 that receives and supports them together. The illustrated embodiment shows a case where the fruit B to be packaged is a relatively large bud.

  Each storage recess 11 of the buffer container 10 is formed in an arbitrary shape, size, and depth corresponding to the fruit B to be stored. For example, when the fruit B is a cocoon, the flat surface has a deformed ellipse shape corresponding to the shape of the cocoon, and the bottom part is recessed so as to form a rounded recess.

  In the embodiment of FIGS. 1 to 6, the buffer container 10 is a 12-packed container 10 </ b> A in which the storage recesses 11 having a shape corresponding to the basket of the fruit B to be stored are formed in four vertical rows of four. As shown in the figure, the deformed elliptical storage recesses 11 in each row are recessed in parallel in an oblique direction with respect to the vertical direction, and the storage recess rows a, a on both sides and the central storage recesses A non-recessed portion 12 having a certain area is left between the rows b. In the case of the figure, six non-recessed portions 12 surrounded by a total of four storage recesses 11 in each row are formed at intervals in the vertical and horizontal directions. The non-recessed portion 12 may be continuously formed in the vertical direction depending on the interval between the storage recess rows a and b.

  The support container 20 has an outer shape corresponding to the buffer container 10, has a side wall portion 23 for receiving the peripheral edge portion 13 of the buffer container 10, and storage recess rows a and b of the buffer container 10. A protruding support portion 22 that supports a portion between the storage recess rows a and b is formed to protrude upward from the bottom surface 21 at an inward portion corresponding to the gap. The protrusion support portion 22 includes a part of the non-recessed portion 12 between the storage recess rows a and b or a part in the vicinity thereof at a plurality of positions spaced in the direction (vertical direction) along the storage recess row. A top 22a is formed to receive the location. Accordingly, the buffer container 10 can be supported at a plurality of locations in the inner part (FIG. 3), and the storage recess 11 can be supported by being floated from the bottom surface 21 of the support container 20 in this support state. The elastic displacement in the vertical direction of the recess 11 can be allowed (FIGS. 4 to 6).

  Furthermore, at least one top portion 22a-1 of the plurality of top portions 22a in the projecting support portion 22 is formed in a horizontally long shape, and in the support state of the buffer container 10, the top portion 22a-1 is the storage recess 11. It is provided so that the movement of the buffer container 10 in the vertical direction along the storage recess row can be restricted by being locked with respect to the side portion (FIGS. 4 to 6). The other long portion 22a is formed in a vertically long shape so that it can be easily fitted between the storage recess rows a and b.

Each top portion 22a of the projecting support portion 22 is rounded, and the buffer container 10 may be made of a flexible foamed resin sheet, so that the top portion 22a is formed on the non- recessed portion 12. It can be received and received without any problem at a position shifted from the position.

  In the case of the figure, in the state where the buffer container 10 is combined with the support container 20 according to the arrangement of the three non-recessed portions 12 between the storage recess rows a and b in the buffer container 10, the three The top portions 22a of the protruding support portions 22 are provided at three positions corresponding to the partial portions of the non-recessed portions 12, so that the top portions 22a receive the partial portions of the non-recessed portions 12 respectively. Is formed.

  The protrusion support portion 22 differs depending on the number of storage recesses 11 and the number of rows of the buffer container 10, but is not necessarily provided between the storage recess rows as shown, and the top portions 22 a and 22 a 1 are not necessarily provided. However, it is not always necessary to provide the corresponding portions of the non-recessed portion 12 between the storage recess rows as shown in the figure, and if it can support the inner portion of the buffer container 10, one location, Preferably, the top 22a is provided at two or more protruding support portions 22, and at least one of the top portions 22a is formed in a horizontally long shape as shown in the drawing.

  Further, as the protruding support part 22, it is possible to form it independently for each top part 22a, but in order to give the protruding support part 22 a rib-like reinforcing effect, as shown in the figure, It is preferable to form it continuously in at least one vertical and horizontal direction (the vertical direction in the figure). In particular, the rib-like reinforcement effect is increased by being formed continuously with the opposing side wall portions 23.

  The fruit wrapping container A of the present invention uses the protruding support part 22 and the top part 22a of the support container 20, and the same support container 20 as described above even when the buffer container 10 is a 15-packed container 10B. It is provided so that it can be used in combination.

  For example, the buffer container 10 in FIGS. 7 to 9 has five storage recesses 11 each having the same outer shape as the 12-pack container 10A and slightly smaller than the storage recess 11 of the 12-pack container 10A. 15 rows of containers 10B formed so as to be parallel to each other in three vertical rows with the plane shape being inclined with respect to the vertical direction, and each of the storage recess rows a, a on both sides and the central storage recess row b Four non-recessed portions 12 are formed at intervals between the rows. The spacing between the storage recess rows a and b is the same as that of the 12-packed container 10A. By using the same support container 20 as that of the 12-packed container 10A, the buffer The storage recess rows a and b of the container 10 can be supported by the protruding support portion 22, and the non-recessed portion 12 or a part of the vicinity thereof can be received by the top portion 22 a of the protruding support portion 22. Is formed.

  In particular, the 12-packed container 10A and the 15-packed container 10B are formed by shifting the position of the non-recessed portion 12 due to the difference in the number and size of the storage recesses 11. For example, even if the non-recessed portion 12 close to both ends in the longitudinal direction is partially overlapped, the position of the non-recessed portion 12 at the inner position is shifted. The top portion 22a of the portion 22 is rounded at the end, or the height of the top portion 22a other than the horizontally long top portion 22a-1 is slightly lowered so that it can be received at a location near the non-recessed portion 12 as well. To form.

  Thereby, also in the 15-packed container 10B, the non-recessed portion 12 or a portion near the ancestor can be supported by the top portion 22a of the protruding support portion 22 (FIGS. 8 and 9). In other words, the support container 20 can be used for the two kinds of containers 10A and 10B, which are the 12-pack and the 15-pack. In other words, the 12 kinds and 15 pieces of the two containers 10A and 10B can be selectively combined with the support container 20 having the same shape.

  Note that, similarly to the above, the buffer containers different in the number of the storage recesses 11 other than the two types of containers 10A and 10B packed in 12 pieces and 15 pieces are formed between a plurality of storage recess rows. As long as at least a part of the non-recessed portion or its vicinity can be received by the top portion 22a of the protruding support portion 22 of the support container 20, it can be used in combination with the same support container 20 as described above.

  As the flexible foamed resin sheet used for the buffer container 10 described above, a foamed sheet of a polyolefin-based resin such as a polyethylene-based resin, a polypropylene-based resin, and an olefin-based copolymer or other soft synthetic resin is used. It is done. Among them, a polyethylene resin foam sheet having flexibility and toughness is preferably used. In the case of a foam sheet of a polyethylene resin, a foamed sheet having a foaming ratio of 15 to 50 times and a thickness of 0.5 to 5 mm is usually used, although it varies depending on the type of fruit to be packaged and the number of stored fruits.

  Examples of the synthetic resin sheet having good shape retention used for the support container 20 include polystyrene resins such as copolymers mainly composed of polystyrene and styrene, polyester resins such as polyvinyl chloride resin and polyethylene terephthalate, and the like. A hard synthetic resin sheet or a foamed sheet of the resin that is moderately elastic and can be expected to have a buffering property is used. Among them, a polystyrene resin foam sheet having good moldability and good shape retention is preferably used. In the case of a foamed sheet of polystyrene-based resin, those having an expansion ratio of 5 to 25 times and a thickness of 0.5 to 5 mm are usually used.

  According to the fruit packaging container A of the above-described embodiment, it is used for packaging a fruit B such as a relatively large grain, and in this use, a buffer made of a flexible foamed resin sheet having a storage recess 11 is used. The container 10 is, for example, a support container made of a synthetic resin sheet having a shape-retaining property by selecting one of the 12-packed container 10A and the 15-packed container 10B according to the number of fruits B to be packed. 20 is used in combination.

  In this use, the buffer container 10 is supported by the side wall portion 23 of the support container 20 in both cases of the 12-packed container 10A and the 15-packed container 10B. The portion between the storage recess rows a and b in the inward portion is supported by the protruding support portion 22. That is, the non-recessed portion 12 other than the storage recess 11 is supported by a plurality of top portions 22 a of the projecting support portion 22 included in the support container 20 at a plurality of locations in the vicinity of the non-recessed portion 12. It is held in a floating state (FIGS. 3 to 6 and FIGS. 8 and 9).

  In this support state, the protruding support portion 22 only contacts the outer surface of the storage recess 11 between the storage recess rows a and b of the buffer container 10, and the protrusion support portion 22 is flexible. The elasticity of the storage recess 11 of the container 10 is not suppressed, and the swelling and displacement of the storage recess 11 using the elasticity of the material are not restricted. Therefore, it is possible to exhibit a good buffering effect against vibration and impact during transportation. Moreover, it can respond easily to variations in the size and shape of the fruit to be stored.

  In addition, since at least one of the top portions 22a-1 of the plurality of top portions 22a of the protruding support portion 22 of the support container 20 is formed in a horizontally long shape, the horizontally long top portion 22a-1 is not in the above-described support state. It is in a state of being locked in a direction along the storage recess rows a and b with respect to a portion other than the recessed portion 12, and moves in a direction along the storage recess row of the buffer container 10 due to vibration during transportation. The buffer container 10 can be positioned at a predetermined position and can be stably held.

  That is, the protruding support portions 22 in the support container 20 are formed continuously in the vertical direction as shown in the figure, and the top portions formed at intervals in the longitudinal direction of the protruding support portions 22 are normal vertically long ones. The buffer container 10 supported thereby may move in the vertical direction due to vibration during transportation, etc. In the present invention, at least one top portion 22a-1 of the projecting support portion 22 is horizontally long as described above. Thus, by adopting a structure in which it is locked at a place other than the non-recessed portion 12, it can be held stably without fear of shifting as described above.

  In addition, as a buffer container 10 for one kind of support container 20, one kind of two or more kinds of containers such as a container 10A filled with 12 pieces and a container 10B filled with 15 pieces can be selectively used. Since the support containers 20 can be used in common for different numbers of assortments, it is not necessary to prepare support containers molded for each assortment number, and the types of support containers can be reduced. There are fewer types of molding dies, and molding costs can be reduced.

  The fruit packaging container of the present invention can be suitably used as a fruit packaging container for packaging fruit such as strawberries, persimmons, and non-flowered fruits one by one.
