JP7108581B2 - Lid member for strawberry container - Google Patents

Description

When the strawberries are stored and displayed in a predetermined rectangular strawberry container when viewed from the top when selling strawberries at a store, the present invention can be used even if the size of the container for storing the strawberries varies even slightly. To provide a general-purpose lid member for a strawberry container capable of protecting stored strawberries by enabling the lid to cover any of the differences even if the form of fitting with the lid or the like is different. Regarding.

Conventionally, when strawberries are sold at supermarkets and convenience stores, for example, when stored in a strawberry container molded with a thin sheet of synthetic resin, they are arranged in rows to prevent scratches on the surface, and other strawberries are sold. It is separated and stored separately. Strawberry containers called regular packs, which are formed in a rectangular shape when viewed from the top, are generally housed in an assembly storage container made of corrugated board in which two strawberries are arranged side by side vertically and horizontally, for example. Therefore, it is transported from the production area to the store.

In view of such distribution circumstances, the weight of strawberries stored in a strawberry container is kept within a substantially constant range of, for example, about 250 to 300 g. , length, height, and the like.

However, in recent years, there are many types of strawberries due to breed improvement in each production area, and the grain size, shape, etc. vary depending on the type. Strawberry containers corresponding to each type are proposed so that the appearance at the time of storage looks best by varying the number of stored strawberries corresponding to the variety, the weight according to the weight, and the arrangement method when storing in the container. As a result, the width, length, and height of the strawberry container itself, as well as the inclination angle of the side wall, the folded-back fitting flange at the opening for reinforcement, etc., will differ even slightly. The actual situation is that the shape of the lid member is completely different from each other in terms of size and the like, in order to have a fitting shape that is tightly fitted to the opening of the strawberry container.

Therefore, various strawberry containers and corresponding lid members have been proposed in the past. There are a packaging container for a strawberry container shown in Patent Document 4, and the like. The covering lid of Patent Document 1 is formed by applying an adhesive strip to the vicinity of both ends of a synthetic resin film that covers the opening of the strawberry container. The container for strawberries of Patent Document 2 is provided with depressions, pillars, and protrusions so as to individually partition the strawberries to be stored in the container body and the lid. The packaging container of Patent Literature 3 suppresses the movement of strawberries contained in the container body by the elasticity of the stretchable film sheet at the bottom opening of the cover, and the bottom surface of the container body is provided with protrusions that restrain the movement of the strawberries and the like. . The lid of Patent Document 4 is formed by forming an air circulating portion in a lid body fitted to a storage container, and forming a gap for air circulation in a fitting edge of the fitted storage container.

However, since the covering lid of Patent Document 1 is simply a thin synthetic resin film, it can be used even if the shape and size of the container body are different. strawberries will be crushed and lose their commercial value. Even if the container of Patent Document 2 can protect the strawberries individually, if the shape and size are different, it is necessary to form dents, pillars, and projections corresponding to each, so it is necessary to prepare a plurality of types of containers. be. The same problem exists in the container body of the packaging container of Patent Document 3 as well. The lid of Patent Document 4 merely aims at air circulation between the inside and outside of the container, and does not have a general-purpose fitting form of the lid that can correspond to different container body shapes.

Therefore, the present invention was created in view of the conventional circumstances as described above, and is suitable for strawberry containers called regular packs, which are variously formed according to various differences in production areas and varieties. Even if there are slight differences in the size of the opening of the strawberry container, the shape of the fitting flange formed in a folded shape for reinforcement, etc., etc., it can be handled for each different strawberry container. To provide a general purpose lid member for a strawberry container which eliminates the need to form and prepare various lid members separately for each strawberry container and which can be applied to any strawberry container.

It should be noted that the reference numerals added in the sections for the means for solving the above problems and the section for the effect of the invention are provided for easy reference to the parts showing the constituent parts described in the drawings. The present invention is not limited to the structures, shapes, etc. indicated by these descriptions, reference numerals, etc. in the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS It is a perspective view which shows one form for implementing this invention with the strawberry container of an example to which a lid|cover is applied. It is a cross-sectional view of the strawberry container in use with the lid on. Fig. 10 is an enlarged cross-sectional view of a main part of the same strawberry container used when the opening flanges have different flange heights; FIG. 11 is a plan view of the essential parts when used in a case where the strawberry container has different opening lengths. FIG. 10 is an enlarged plan view of a main part of the same strawberry container used in a case where the angular corners of the opening flange are different;

Hereinafter, one mode for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the drawings is a predetermined strawberry container P, which is a so-called regular bag having a rectangular shape when viewed from the top as shown in the drawing. It is a lid body that closes the opening of the strawberry container P to protect the stored strawberries S.

The strawberry container P has a folded-back reinforcing fitting flange F formed on the periphery of the opening, so that the corners of the strawberry container P are arc-shaped when viewed from the top, so that the strawberry container P has a substantially rectangular shape with a predetermined depth. presenting. The lid body 1 fitted to the opening of the strawberry container P has a covering width corresponding to the opening width W of the short side and the opening length L of the long side of the opening of the strawberry container P. , with a rectangular bottom opening having an enveloping length.

Both the strawberry container P and the lid body 1 are made of a thin synthetic resin sheet material and are formed by, for example, vacuum forming. It is formed to have a width and length suitable for storage in storage compartments partitioned in a corrugated cardboard assembly storage container (not shown) for storage. By the way, when the present inventor collected and examined various strawberry containers P that have been conventionally provided, the opening width W was approximately 111 mm, and the difference in the opening width W was in the range of 0.5 to 2 mm. The opening length L is about 165 mm, and the range of difference in the opening length L is about 10 mm. It was found that the maximum width of the fitting flange F was about 10 mm, and the difference in height was about 4 to 10 mm.

The strawberry container P itself should be suitable for being stored in the storage compartment in the assembled storage container. The opening width W including the fitting flange F, the opening length L, etc. are appropriately set within the range of being stored in each storage compartment so that the weight is approximately constant, for example, 250 to 300 g, and the appearance is good. , and the strawberry container P is formed.

The lid body 1 that covers the strawberry container P has a dome shape that bulges upward so as to protect the stored strawberries S. It is formed so as to be fitted snugly, and in the present invention, it is constructed as a general-purpose one so as to correspond to various openings of strawberry containers P which are appropriately changed and selected.

For this reason, a container fitting portion 10 is formed at the opening of the lower surface of the lid body 1 so as to cover the opening of the strawberry container P so as to fit snugly into the opening. The container fitting portion 10 has a maximum opening width W on the short side of the opening of the strawberry container P and a maximum opening width W on the long side of the opening of the strawberry container P along the outer shape of the rectangular opening of the strawberry container P. It has a rectangular bottom opening with a covering width and a covering length that are not small compared to the opening length L, respectively. By doing this, in the opening of the strawberry container P that is generally provided, if it is formed with the minimum opening width W and the minimum opening length L, the wrapping width and the wrapping length The difference in height becomes a gap, and the strawberry container P and the lid body 1 are engaged and supported by generating a margin for sliding movement within the gap range of the gap difference.

The container fitting portion 10 itself consists of a flange covering portion 11 that protrudes outward along the edge of the lower opening of the lid body 1 so as to cover the fitting flange F of the strawberry container P, and this flange covering portion. an engaging recess 12 recessed inwardly of the flange wrap 11 to engage the lower edge of the fitting flange F covered by 11; a flange support portion 13 defined within the flange wrap portion 11 to support a support height not smaller than the maximum flange height H of the mating flange F;

The flange covering portion 11 has a substantially "shape" in cross section from an upper wall portion 11A along the upper edge surface of the fitting flange F and a side wall portion 11B along the outer surface of the folded outer portion. It is formed over the entire area including the covering width area, the covering length area, and the corners of the bottom opening of the main body 1 .

The engaging recess 12 engages with the lower end of the outer portion of the folded portion of the fitting flange F when the fitting flange F is covered by the flange covering portion 11, and the flange covering portion 11 is fitted to the fitting flange. When it is put on the flange F, the engaging recess 12 abuts against the outer portion of the fitting flange F, overcoming it and forcibly engaging with the lower end.

The cross-sectional shape of this engagement recess 12 is a guide slope that is inclined inwardly so as to gradually become recessed inward of the lid body 1 from the lower edge of the side wall portion 11B of the flange covering portion 11 to the upper wall portion 11A side. An edge 12A and an engagement slanted edge 12B that is folded back and slanted outward from the upper part of the guide slanted edge 12A to the upper part form a substantially dogleg shape. The engagement recess 12 itself is formed by undercut processing during vacuum molding, for example.

The size of the engaging recess 12 itself is set to about 2/5 of the height of the flange covering portion 11, and the height ratio between the guide slanted edge 12A and the engaging slanted edge 12B is are approximately 4:1 to 3:1, and are folded at approximately right angles between them. By doing so, the upper portion of the engaging inclined edge 12B is continuous with the side wall portion 11B of the flange covering portion 11, and the continuous portion forms a slightly downwardly inclined stepped portion. The lower end of the fitting flange F when covered with the strawberry container P is engaged and supported.

The formation ratio of the guide slanted edge 12A and the engaging slanted edge 12B in the engaging recess 12 is not limited to the above ratio, and the depth of the recess inward of the lid body 1 is determined by the fitting. It is sufficient if the depth and width are sufficient to engage the lower edge of the flange F.

The inside of the side wall portion 11B of the flange covering portion 11 extending from the engagement recess 12 to the upper wall portion 11A of the flange covering portion 11 serves as the flange support portion 13 described above. The support height of the flange support portion 13 itself, that is, the height interval from the upper surface of the corner portion of the engagement recess 12 to the inner surface of the upper wall portion 11A is the maximum flange height of the fitting flange F of the strawberry container P. It is assumed that it is not smaller (lower) than the height H. By doing so, even a strawberry container (P1) having a low flange height H of the fitting flange F (F1) can be engaged with the engaging recess 12, and the lid body 1 can be attached to the strawberry container P. Even if the lid body 1 slides up and down, the lid body 1 is separated from the strawberry container P and does not come off (see FIG. 3).

In this flange support portion 13 , the lower end of the fitting flange F may be engaged in the engagement recess 12 depending on the difference in the opening width W of the entire strawberry container P including the fitting flange F or the flange height H. It may be located on the upper end of the beveled edge 12B or on the corner portion of the engagement recess 12, but in any case it is located anywhere on the beveled edge 12B.

The engagement recesses 12 are provided at the edges near the four corners of the lid body 1, which is rectangular in plan view in the drawing, and are provided at the ends of the short sides and the ends of the long sides. Although they are provided at a total of four locations, they are not limited to this, and are provided at approximately the central portion of each edge or at an appropriate number of locations where they are reliably engaged with the strawberry container P. By arranging the engaging recesses 12 near the corners, the opening of the strawberry container P itself or the lid body 1 itself is flexed so that the disengagement of the engaged state due to the positional deviation inward or outward; Consideration should be given to prevent separation.

The interval between the engaging recesses 12 along the left-right direction, that is, the interval between the upper ends of the engaging inclined edges 12B is the interval of the opening width W on the short side including the fitting flange F in the strawberry container P. (length) corresponds approximately to This is because, as described above, most of the strawberry containers P that can be covered by the lid member according to the present invention have almost the same width even if there is a slight difference. (See Figure 4). However, even if the opening width W of the entire strawberry container P is slightly larger than the interval between the upper ends of the engaging inclined edges 12B, the difference is so small that it can be forcibly fitted.

In addition, the interval between the upper ends of the engaging inclined edges 12B in the engaging recess 12 along the front-rear direction perpendicular to the left-right direction is not smaller than the maximum opening length L of the strawberry container P. It's on. By doing so, in the case of the strawberry container (P1) having an opening length L shorter than the strawberry container P having the maximum opening length L, the strawberry container (P1) is engaged with the engaging recess 12 along the left-right direction. This is because even if the slide movement is allowed in the front-rear direction, it is possible to maintain the cover state of the lid body 1 with respect to the strawberry container (P1) (see FIG. 4). However, even if the opening length L of the entire strawberry container P is slightly larger than the interval between the upper ends of the engaging inclined edges 12B, the difference is so small that it can be dealt with by forcibly fitting them together. , and the length that is not small includes such a case.

In addition, the four corners of the corners of the lid body 1 are formed in an arc shape when viewed from the top, and when the lid body 1 is put on the strawberry container P, the corners of the four corners of the strawberry container P are likewise arcuate. It is designed to be stored without sticking out. Therefore, the arc diameters of the four corners of the lid body 1 are formed smaller than the flange arc diameter R of the strawberry container P, and are smaller than the minimum flange arc diameter R of the arc-shaped corners of the strawberry container P. It is set to an arc diameter that is not large. By doing this, regardless of whether the strawberry container P or the strawberry container (P1) has a small flange arc diameter R at the corner, any of the fitting flanges F, (F1) can be attached to the corner of the lid body 1. The corners can be covered (see Figure 5).

In the drawing, reference numeral 2 denotes an air circulation portion formed in a recessed shape in the lower part of the side wall of the lid body 1 in order to facilitate air circulation inside and outside the container when the lid body 1 is put on the strawberry container P, and 3. , a plurality of groove-shaped reinforcing portions for reinforcing the side wall of the lid body 1;

Next, an example of the use of this will be described. The opening of a predetermined strawberry container P containing strawberries S may be covered with the lid body 1, and the flange covering portion 11 is outside the fitting flange F of the strawberry container P. The guide inclined edge 12A of the engaging recess 12 abuts on the outer surface of the portion, and the upper portion of the engaging recess 12 engages with the lower edge of the fitting flange F by riding over the fitting flange F while abutting. The fitting flange F is positioned within the flange enclosing portion 11 so that the lid body 1 covers the strawberry container P. As shown in FIG.

When the flange heights H of the fitting flanges F are different, the strawberry container (P2) having the maximum flange height H supports the fitting flange (F2) over the entire flange support portion 13, and the flange height H is low. In the case of the strawberry container (P1), for example, when the lid body 1 is lifted, even if the fitting flange (F1) moves up and down within the flange support portion 13, the upper part of the engaging recess 12 does not move the fitting flange (F1). By engaging with (F1), the lid body 1 does not come off from the strawberry container P (see FIG. 3).

When the opening width W of the strawberry container P is small, the lower end of the fitting flange F2 is engaged with the inner corner portion of the engagement recess 12, and the fitting flange F2 is positioned on the flange support portion 13. The lid body 1 covers the opening of the strawberry container P and does not come off from the strawberry container P (see also FIG. 3).

In addition, when the opening length L of the strawberry container P is different, in the strawberry container P having the maximum opening length L, the engaging recess 12 is in the entire covering length of the flange covering portion 11 in the lid body 1. It supports the mating flange F1 that is engaged and supported. In a strawberry container (P1) with a short opening length L, even if it is not tightly fitted in the longitudinal direction and there is a so-called play or margin and it slides, it is supported by the engaging recess 12. The lid body 1 does not come off from the strawberry container (P1) (see FIG. 4).

When the flange arc diameters R are different in the arc-shaped portions of the corners of the strawberry container P, the strawberry container (P1) having the smallest flange arc diameter R is close to the inner edge of the corner corners of the lid body 1. However, the corners of the strawberry container (P1) do not protrude outward from the lid body 1, and the corners of the strawberry container P having a large flange arc diameter R are projected from the inside of the corners of the lid body 1. The lid body 1 does not come off from the strawberry container P even if it is positioned slightly apart (see FIG. 5).
