Description

According to the present invention, when strawberries are mainly sold in stores and are stored and displayed in a predetermined strawberry container that is rectangular when viewed from a plane, the strawberry container that stores the strawberry may have a small size or a small size. A versatile lid member for strawberry containers that can protect the stored strawberries by making it possible to apply the lid in response to any of the differences even if the fitting form with the lid is different. Regarding.

When strawberries are traditionally sold at supermarkets and convenience stores, for example, when they are stored in a strawberry container molded from a thin-walled synthetic resin sheet, they are lined up in order to prevent surface scratches, or other strawberries. It is separated from and stored individually. In addition, a so-called regular pack, which is formed in a rectangular shape when viewed from a flat surface, is generally stored in a corrugated cardboard assembly storage container in which two of them are arranged side by side in the vertical and horizontal directions. As a result, 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 set to be contained within a substantially constant range of, for example, about 250 to 300 g, and the shape of the container is also a predetermined width in the covered form. It is formed in an almost rectangular parallelepiped shape having a length, height, and the like.

However, recently, there are many types of strawberries due to breeding in each production area, and the grain size, shape, etc. of the strawberries vary depending on the type. Since the number of strawberry containers to be stored, the weight of the strawberry containers, and the arrangement method when storing them in the container are different according to the variety and others, strawberry containers corresponding to each have been proposed so that the appearance at the time of storage looks best. As a result, the width, length, height of the strawberry container itself, the inclination angle of the side wall, the folded-shaped fitting flange at the opening for reinforcement, etc. are slightly different, and in response to these differences. In order for the lid member to have a fitting shape that fits tightly into the opening of the strawberry container, the actual situation is that the size and other shapes are completely different according to each.

Therefore, various strawberry containers and lid members corresponding thereto have been conventionally proposed, for example, a covering lid for a fruit and vegetable packaging container shown in Patent Document 1, a strawberry container shown in Patent Document 2, and a lid member shown in Patent Document 3. There are packaging containers, lids for strawberry containers shown in Patent Document 4, and the like. The covering lid of Patent Document 1 is formed by coating adhesive bands near both ends of a synthetic resin film covering the opening of a strawberry container. The strawberry container of Patent Document 2 is provided with a recess, a pillar, and a protrusion so as to individually partition the strawberry to be stored in the container body and the lid. The packaging container of Patent Document 3 is formed by providing a protrusion on the bottom surface of the container body to restrain the movement of strawberries, etc., by suppressing the movement of strawberries stored in the container body by the elasticity of the elastic film sheet opening on the lower surface of the cover. .. The lid of Patent Document 4 is formed by forming an air flow portion in a lid main body fitted to a storage container and forming an air flow gap at a fitting edge of the fitted storage container.

Japanese Unexamined Patent Publication No. 1-167059 Japanese Unexamined Patent Publication No. 8-133369 Japanese Unexamined Patent Publication No. 2010-168083 Registered Utility Model No. 3209462

However, since the covering lid of Patent Document 1 is simply a thin-walled synthetic resin film, it can be used even if the shape and size of the container body are different. On the other hand, for example, when a plurality of containers are purchased at a store, they are stacked in the lower container. Strawberries will be crushed and the commercial value will be impaired. Even if the container of Patent Document 2 can protect strawberries individually, if the shape and size are different, it is necessary to form dents, pillars and protrusions corresponding to each, so it is necessary to prepare a plurality of types of containers. is there. A similar problem exists in the container body of the packaging container of Patent Document 3. The lid of Patent Document 4 merely aims at air flow inside and outside the container, and does not have a versatile lid fitting form that can correspond to different container body shapes.

Therefore, the present invention was created in view of various existing circumstances as described above, and is formed in various ways depending on various differences in production area and variety, for example, in any of the strawberry containers called regular packs. Even if the opening shape of the strawberry container is slightly different in size, the fitting flange shape formed in a folded shape for reinforcement, etc. is different, it can be handled for each different strawberry container. It is not necessary to form and prepare various lid members separately, and it is an object of the present invention to provide a versatile lid member for a strawberry container that can be used for any strawberry container.

In order to solve the above-mentioned problems, in the present invention, it is a lid member for a strawberry container that covers the opening of the strawberry container P that has a substantially rectangular shape when viewed from a plane, and the lid body of the lid member for the strawberry container. 1 has a container fitting portion 10 that covers the fitting flange F formed in the opening of the strawberry container P, and the container fitting portion 10 has an opening on the lower surface of the lid body 1 so as to cover the fitting flange F. Inside the flange covering portion 11 so as to engage with the flange covering portion 11 that bulges outward along the peripheral edge and the lower edge of the fitting flange F covered by the flange covering portion 11. The engagement recess 12 is recessed in the flange, and the flange support portion 13 is partitioned in the flange covering portion 11 so as to support the fitting flange F on the engagement recess 12. It is characterized by.
The engaging recess 12 can be arranged and configured in the vicinity of the corner portion of the flange covering portion 11.
The flange covering portion 11 can be configured to have a covering width corresponding to the opening width W of the opening of the strawberry container P and a lower surface opening having a covering length corresponding to the maximum opening length L. ..
The engaging recess 12 includes a guide inclined edge 12A that is inclined inward so as to gradually dent inward of the lid main 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. The guide inclined edge 12A has a substantially "dogleg" shape from the engaging inclined edge 12B which is folded back and inclined outward as it goes upward, and the lid body 1 is attached to the fitting flange F. When covered, the outer surface of the outer portion of the fitting flange F slides while contacting the engaging recess 12, and the lower edge of the fitting flange F is engaged and supported on the engaging recess 12. can do.
The covering length of the flange covering portion 11 can be configured to be not smaller than the maximum opening length L of the opening in the strawberry container P.
The distance between the engaging recesses 12 along the width direction can be configured to be not smaller than the minimum opening width W of the opening in the strawberry container P.
The support height of the flange support portion 13 can be configured to be not smaller than the maximum flange height H of the fitting flange F of the strawberry container P.
The arc diameter at the corner of the flange covering portion 11 can be configured to be not larger than the minimum flange arc diameter R at the arc-shaped corner of the fitting flange F.

In the lid member for a strawberry container according to the present invention configured as described above, the engaging recess 12 provided in the side wall portion of the flange covering portion 11 in the container fitting portion 10 of the lid main body 1 is a flange. By covering the fitting flange F of the strawberry container P with the covering portion 11, the lower edge of the fitting flange F is engaged and supported, the strawberry container P is covered by the lid body 1, and the strawberry S stored in the strawberry container P is protected. Let me.
The engaging recess 12 arranged near the corner of the flange covering portion 11 engages and supports the corner of the fitting flange F of the strawberry container P, and engages and supports the lid body 1 due to the bending that may occur. Maintains the engagement support state without being affected by separation and dropping.
The covering length of the flange covering portion 11 is not smaller than the maximum opening length L of the opening of the strawberry container P, and the opening length L of the various strawberry containers P is different regardless of the length. , Cover and cover them with the lid body 1.
The engaging recess 12 of the flange covering portion 11 engages and supports the lower edge of the fitting flange F when the lid body 1 is placed on the strawberry container P, and has a maximum flange height H of the fitting flange F. The flange support portion 13 having a support height that is not relatively small causes the fitting flange F to be supported by the flange covering portion 11 regardless of the height of the flange height H in various strawberry containers P.
Since the distance between the engaging recesses 12 along the width direction is not smaller than the minimum opening width W in the strawberry container P, the fitting flange F is engaged and supported even if the widths in the strawberry container P are different. The strawberry container P is covered with the lid body 1.
The arc diameter of the flange covering portion 11 which is not larger than the minimum flange arc diameter R at the arc-shaped corners of the fitting flange F is the flange arc diameter of the arc-shaped corners of various strawberry containers P. Regardless of the size of R, the strawberry container P is covered with the corners of the strawberry container P without protruding.

Since the present invention is configured as described above, for example, a lid member is separately formed so as to be tightly fitted to the strawberry container P which is individually formed according to each strawberry variety. Without this, it is possible to obtain versatility that allows the lid member according to the present invention to fit snugly with the fitting flange F of the strawberry container P having different opening shapes.

That is, in the present invention, the container fitting portion 10 that covers the fitting flange F of the strawberry container P is the flange covering portion 11 that bulges outward along the lower surface opening edge of the lid body 1. An engaging recess 12 that engages with the lower edge of the fitting flange F, and a flange support portion 13 that is partitioned within the flange covering portion 11 so as to support the fitting flange F on the engaging recess 12. Because it is made up of. As a result, the openings of various strawberry containers P having different opening lengths L, flange heights H, etc. in the fitting flange F can be covered by the versatile lid body 1, and various different lid members are prepared for each. You don't have to.

Further, by arranging the engaging recess 12 near the corner of the flange covering portion 11, the strawberry container P itself and the opening of the lid body 1 itself are not affected by the inward and outward bending. The fitting flange F due to the engaging recess 12 is not disengaged or separated.

The covering length of the flange covering portion 11 is not smaller than the maximum opening length L of the fitting flange F of the strawberry container P, and the minimum opening width between the engaging recesses 12 along the width direction is the minimum. The support height of the flange covering portion 11 is not smaller than that of the maximum flange height H of the fitting flange F, and the arc diameter at the corner of the flange covering portion 11 is not small. The length of the opening length L in various strawberry containers P and the flange in the fitting flange F are not small compared to the minimum flange arc diameter R in the arcuate corner of the fitting flange F. Even if there is a difference in the height H and the flange arc diameter R at the corners, it can be applied to any strawberry container P and is excellent in versatility.

It should be noted that the reference numerals added in each of the means for solving the above-mentioned problems and the section of the effect of the invention are added in order to facilitate reference with the parts indicating the constituent parts described in the drawings. The present invention is not limited to the structure, shape, etc. indicated by these descriptions, reference numerals, etc. in the drawings.

It is a perspective view which shows one embodiment for carrying out this invention together with an example strawberry container to which a lid is applied. It is also a cross-sectional view in a used state with a strawberry container covered. It is also an enlarged cross-sectional view of a main part when used when the flange height of the opening flange in the strawberry container is different. Similarly, it is a plan view of a main part when used when the length of the opening length in the strawberry container is different. Similarly, it is an enlarged plan view of a main part when it is used when the corners of the opening flange in the strawberry container are different.

Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the drawings is referred to as a predetermined strawberry container P, a so-called regular bag having a rectangular shape when viewed from a plane as shown in the drawing. It is a lid body that closes the opening portion of the strawberry container P to be stored and protects the stored strawberry S.

The strawberry container P has a substantially rectangular shape having a predetermined depth, with corners having an arc shape when viewed from a plane by forming a folded fitting flange F on the peripheral edge of the opening. It is presented. The lid body 1 fitted to the opening of the strawberry container P has a covering width corresponding to each of the opening width W of the short side length and the opening length L of the long side length at the opening of the strawberry container P. A rectangular lower surface opening having a cover length.

Both the strawberry container P and the lid body 1 are formed by, for example, vacuum forming using a thin film sheet material made of synthetic resin as a material, and the strawberry container P itself is generally made up of two in each of the vertical and horizontal directions. It is formed according to the width and length suitable for being stored in the storage compartment partitioned in the corrugated cardboard assembly storage container (not shown). By the way, when the present inventor collected and examined various strawberry containers P conventionally provided, the opening width W was about 111 mm, and the range of difference on the side of the opening width W was 0.5 to 2 mm. It can be said that there is almost no difference in degree, and the opening length L is about 165 mm, and the range of difference in this opening length L is about 10 mm, which is used for reinforcement provided in the opening of the strawberry container P. It was found that the maximum width of the fitting flange F was about 10 mm, and the range of height difference was about 4 to 10 mm.

Then, the strawberry container P itself may be suitable for being stored in the storage compartment of the assembled storage container. For example, the number of strawberry containers P stored in the strawberry container P and the storage form are corresponding to different varieties of the strawberry S. The opening width W including the fitting flange F, the opening length L, and the like are appropriately adjusted within a range in which the weight is almost constant, for example, 250 to 300 g, and the weight is stored in each storage section so as to have a good appearance. The strawberry container P is formed by being changed to.

The lid main body 1 to be attached to the strawberry container P has a dome shape that bulges upward so as to protect the stored strawberry S, and is formed at the opening of the strawberry container P that has been changed and selected. It is formed so that it fits snugly, and in the present invention, it is configured to be versatile so as to correspond to variously different openings of the strawberry container P, which are appropriately modified and selected.

Therefore, the lower surface opening of the lid main body 1 is formed with a container fitting portion 10 that fits snugly with the opening so as to cover the opening of the strawberry container P. The container fitting portion 10 has a maximum opening width W on the short side side and a maximum opening width W on the long side, which are different from each other along the outer shape of the rectangular opening of the strawberry container P. It is a rectangular lower surface opening having a covering width and a covering length that are not smaller than the opening length L, respectively. By doing so, in the case where the opening of the generally provided strawberry container P is formed as having the minimum opening width W and the minimum opening length L, the covering width and the covering length The difference on the upper side becomes a gap, and the strawberry container P and the lid main body 1 are provided with a margin for sliding movement within the interval range of the gap difference to support engagement.

The container fitting portion 10 itself includes a flange covering portion 11 that bulges outward along the lower surface opening edge of the lid body 1 so as to cover the fitting flange F in the strawberry container P, and the flange covering portion. The engaging recess 12 recessed inward of the flange covering portion 11 so as to engage the lower edge of the fitting flange F covered by 11, and the fitting flange F on the engaging recess 12. A flange support portion 13 is provided which is set to a support height that is not smaller than the maximum flange height H of the fitting flange F so as to support and is partitioned within the flange covering portion 11.

In cross section, the flange covering portion 11 has a substantially "shaped shape" from the upper wall portion 11A along the upper edge surface of the fitting flange F and the 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 corner portion of the lower surface opening of the main body 1.

When the fitting flange F is covered by the flange covering portion 11, the engaging recess 12 engages with the lower end of the outer portion of the folded portion of the fitting flange F, and the flange covering portion 11 is fitted with the fitting flange. When it is put on the F, the engaging recess 12 is forced to engage with the lower end by overcoming the fitting flange F while contacting the outer portion of the fitting flange F.

The cross-sectional shape of the engaging recess 12 is a guide inclination that is gradually inclined inward so as to be gradually recessed inward of the lid main body 1 from the lower edge of the side wall portion 11B to the upper wall portion 11A side of the flange covering portion 11. The edge 12A and the engaging inclined edge 12B which is folded back and inclined outward from the upper part of the guide inclined edge 12A form a substantially "dogleg" shape. The engaging recess 12 itself is formed by, for example, an undercut process during vacuum forming.

The size of the engaging recess 12 itself is set to a height of about 2/5 of the height of the flange covering portion 11, and the height ratio between the guide inclined edge 12A and the engaging inclined edge 12B. Is about 4: 1 to 3: 1 and is folded back at a substantially right angle 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 at the continuous portion, a step portion slightly inclined downward is formed on the step portion. The lower end of the fitting flange F when it is put on the strawberry container P is engaged and supported.

The formation ratios of the guide inclined edge 12A and the engaged inclined edge 12B in the engaging recess 12 are not limited to the above ratios, and the depth of the recess inward of the lid body 1 is fitted. It suffices if the depth width is sufficient to engage the lower edge of the flange F.

The inside of the side wall portion 11B of the flange covering portion 11 from the top of the engaging recess 12 to the upper wall portion 11A of the flange covering portion 11 is the flange supporting portion 13. The support height of the flange support portion 13 itself, that is, the height interval from the upper surface of the corner portion in the engaging 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 H. By doing so, even the 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 engaged with the strawberry container P. Even if it slides up and down, the lid body 1 separates from the strawberry container P and does not come off (see FIG. 3).

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

The engaging recesses 12 are provided on the edges near the four corners, which are the corners of the lid body 1 which is rectangular in the drawing, and the ends of the short sides are the ends of the long sides. It is provided at a total of four places, but is not limited to this, and is provided at an appropriate position and number at substantially the center of each edge or at a position and number where the strawberry container P is surely engaged. By arranging the engaging recess 12 in the vicinity of the corner, the engagement state is disengaged due to the inward or outward displacement due to the bending generated in the opening of the strawberry container P itself or the lid body 1. Care should be taken to prevent separation.

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

Further, the distance between the upper ends of the engaging inclined edges 12B in the engaging recess 12 along the front-rear direction orthogonal to the left-right direction is not small compared to the maximum opening length L in the strawberry container P. I'm sorry. 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 in a state of being engaged by the engaging recesses 12 along the left-right direction. This is because the lid body 1 can be maintained in the lid state with respect to the strawberry container (P1) even if the slide movement is possible in the front-rear direction (see FIG. 4). However, even if the opening length L of the entire strawberry container P is slightly larger than the distance between the upper ends of the engaging inclined edges 12B, the difference is small, so it can be dealt with by forcibly fitting. , Not small length includes such cases.

Further, the four corners of the corners of the lid body 1 are formed in an arc shape when viewed from a plane, 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 also arcuate. It is designed so that it can be stored without sticking out. Therefore, the arc diameters at 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 arcuate corners of the strawberry container P. The arc diameter is set to be not large. By doing so, regardless of whether the strawberry container P has a large flange arc diameter R at the corner corner or the strawberry container (P1) has a small diameter R, any of the fitting flanges F and (F1) can be attached to the corner of the lid body 1. It can be covered with a corner (see FIG. 5).

In the figure, reference numeral 2 is an air flow portion formed in a recessed shape at the lower part of the side wall of the lid main body 1 in order to allow air flow inside and outside the container when the lid main body 1 is put on the strawberry container P. , A plurality of groove-shaped reinforcing portions that reinforce the side wall of the lid body 1.

Next, an example of the use of this may be described by covering the opening of a predetermined strawberry container P containing the strawberry S with the lid main 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 overcoming the fitting flange F while abutting. The fitting flange F is positioned in the flange covering portion 11, whereby the lid body 1 covers the strawberry container P.

When the flange height H of the fitting flange F is different, in the strawberry container (P2) having the maximum flange height H, the fitting flange (F2) is supported over the entire flange support portion 13, and the flange height H is low. In the strawberry container (P1), for example, even if the fitting flange (F1) moves up and down in the flange support portion 13 when lifted by the lid body 1, the upper part of the engaging recess 12 is the fitting flange. 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 in the strawberry container P is small, the lower end of the fitting flange F2 engages with the inner corner portion in the engaging recess 12 and the fitting flange F2 is positioned on the flange support portion 13. The lid body 1 covers the opening portion of the strawberry container P and does not come off from the strawberry container P (also see FIG. 3).

Further, 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 formed over the entire covering length of the flange covering portion 11 in the lid body 1. Supports the fitting flange F1 that is engaged and supported. In the strawberry container (P1) having a short opening length L, even if the strawberry container (P1) cannot be fitted tightly in the length direction and may slide and move due to so-called play / margin, it is supported by the engaging recess 12. As a result, the lid body 1 does not come off from the strawberry container (P1) (see FIG. 4).

If the arc-shaped portions of the corners of the strawberry container P have different flange arc diameters R, the strawberry container (P1) having the smallest flange arc diameter R is close to the inner edge of the corners of the lid body 1. However, the corners of the strawberry container (P1) do not travel to the outside of the lid body 1, and the corners of the strawberry container P having a large flange arc diameter R are 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).
