Description

  The present invention relates to a food container in which a container composed of a container body and a lid is formed of a synthetic resin film material. More specifically, in addition to cherry tomatoes, strawberries such as blueberries, gooseberries, strawberry, and cherry The present invention relates to a disposable food container that can be used as a small-sized fruit and vegetables container and can be displayed and sold in a state in which the type and state of stored fruit can be confirmed from the outside.

  Conventionally, it is a container for fresh fruits formed of a synthetic resin film material, which is a disposable food container composed of a container body and a lid, and variously devised according to the type of food to be stored. Forms are offered on the market.

In addition, even with the same small fresh fruits, the packaging forms are diversified. For example, it is necessary to store and sell appropriate quantities that are easy for customers to purchase, such as for singles, couples, and households. Therefore, it is required that the size and shape of the container be made in accordance with the sales unit of food.
Japanese Patent No. 3364800

  Thus, when storing small quantities of small fresh fruits such as cherry tomatoes and blueberries, transporting them for sale, they are stored in multiple layers in cardboard containers, and sold in multiple layers for over-the-counter sales. It is common to be done.

  Accordingly, it is necessary to stably stack the required number of containers between the containers, and it is necessary to reliably protect the contained fruit without the bottom container being crushed.

  On the other hand, since this type of container is a disposable type container that is disposed of after the contents are taken out by the purchaser, it is generally necessary to make it as low-cost as possible. For example, a thin synthetic resin film having a thickness of 0.4 to 0.5 mm is used. Even with thick films, it is only about 0.7 to 0.8 mm.

  However, the present invention provides a more stable load bearing strength when a material film having the same thickness as those of these conventional containers is used, and a container having the same load bearing strength as a conventional container is obtained. For example, it is possible to use a thinner material film, and even if the required multi-stage containers are packed and displayed in a stacked state, they are suitable for the bottom container where the upper load is applied. However, an object of the present invention is to provide a food container that can withstand without being crushed.

A stepped wall 23, a rising wall 24 that rises upward from the stepped wall 23, and a flange 25 that extends from the upper end of the stepped wall 23 toward the outer periphery, and is formed into a shallow square dish shape. The four side walls 22 include a plurality of parallel reinforcing ribs 26 extending in series from the upper end to a part of the inner peripheral direction of the ceiling wall 21, and the ceiling wall 21 of the lid body 2 includes One or a plurality of air holes 4 are formed, and the depth of the container body 1 is about 2 to 3 times the depth of the lid 2.

  In addition, the second device described in claim 2 is a box-shaped container body 1 having an opening 10 in the upper part, a box-shaped lid body 2 covering the upper part of the container body 1, and these on one side. A food container made of a synthetic resin sheet integrally provided with a foldable hinge part 3 to be connected, the container body 1 having a substantially rectangular horizontal bottom wall 11 and each periphery of the bottom wall 11 Four side walls 12 rising from the top, an upper wall 13 extending from the upper end of the side wall 12 toward the outer periphery, a descending wall 14 descending downward from the upper wall 13, and an outer periphery from the lower end thereof. A plurality of parallel reinforcing ribs 16 are formed in a deep box shape with a flange 15 extending toward the top, and the four side walls 12 extend from the periphery of the opening 10 to the inner peripheral direction of the bottom wall 11. And the lid 2 has a substantially rectangular shape that forms a top surface when the lid 2 is in a closed posture. A well wall 21, a four-sided side wall 22 rising from each periphery of the ceiling wall 21 in a non-closed posture, a stepped wall 23 extending from the upper end of the side wall 22 toward the outer periphery, and the stepped wall 23 is formed in a shallow square dish shape having a rising wall 24 rising upward from 23 and a flange 25 extending from the upper end toward the outer peripheral direction, and the four-sided side wall 22 is formed at the upper end A plurality of parallel reinforcing ribs 26 extending in series from the inner wall to a part of the inner circumferential direction of the ceiling wall 21, and one or more air holes 4 are formed in the ceiling wall 21 of the lid 2. The depth of the container body 1 is about 2 to 3 times the depth of the lid 2.

  The structure according to claim 3 is a structure subordinate to the idea according to claim 1 or claim 2, and the container body 1 includes at least one corner of the flange 15. A tongue-shaped lower knob 17 formed in a lower part is formed in the upper part, and the tongue which is raised one step in the closed state at the corner of the lid 2 facing the lower knob 17 when the lid is closed. A piece-shaped upper knob 27 is formed.

  According to the first aspect of the present invention, the container body includes an upper wall extending from the upper end of each side wall in the outer circumferential direction, a descending wall descending downward from its outer end, and further from its lower end. Since the opening portion is provided with a flange extending toward the outer peripheral direction, the opening portion has high strength, and all the four side walls extend from the peripheral portion of the opening to the inner peripheral direction of the bottom wall. Since the parallel reinforcing ribs are provided, even a deep container body has extremely high resistance to the compressive load from above, and does not easily buckle. The body also includes a stepped wall extending from the upper end of the four side walls toward the outer periphery, a rising wall rising upward from the outer periphery, and a flange extending from the upper end toward the outer periphery. The deformation resistance toward the center is extremely high. In addition, the four side walls are provided with a large number of parallel reinforcing ribs extending in series from the upper end to a part of the inner peripheral direction of the ceiling wall, so that the ceiling wall is resistant to vertical compressive loads. Since the air hole is formed in the container, it has an effect that the freshness of the food in the container can be maintained for a long time.

  According to the second aspect of the present invention, the same effect as that of the food container according to the first aspect of the present invention can be obtained, and the container body and the lid covering the upper part thereof can be folded on one side. Since it is a single member integrally formed via the hinge portion, there is an advantage that it is easy to perform a lid closing operation by a machine and that there is no inconvenience that the numbers of the container main body and the lid body do not match.

  According to the third aspect of the present invention, the container body side is formed with a lower knob portion that is one step lower at the opposite corners of the flange between the container body and the lid body, and the lid body side is a single stage in the closed state. Since the raised upper knobs are formed, there is an advantage that these knobs can be easily held by the fingertips and can be easily opened.

  The configuration of the present invention will be described below with reference to the drawings. 1 to 5 show a container of a main embodiment of the present invention as a first embodiment. FIG. 1 is an overall perspective view, FIG. 2 is a plan view, FIG. 3 is a front view, and FIG. FIG. 5 is a left side view of FIG.

  The container shown in the first embodiment is a container mainly for use as a container for cherry tomatoes. The container is a single-piece container integrally formed by a container body 1, a lid body 2, and a hinge portion 3 that connects the container body 1 and the lid body 2 on one side.

  The overall size of the container in the left-right direction in FIG. 2 is about 200 mm, the container body 1 is a square shape of about 100 mm with arcs at the four corners, a depth of about 50 mm, and a depth of the lid 2 of about 20 mm. The synthetic resin material sheet was formed of an APET resin film material having a thickness of 0.25 mm. The ratio of the size (depth) of the container body 1 and the lid body 2 is 5 to 2.

  In forming the container of this embodiment, the container is generally bulged into a predetermined shape using a well-known blow mold, a vacuum mold, or a mold having both means. The synthetic resin sheet material is not particularly limited as long as it is a sheet material conventionally used for manufacturing this type of container. For example, resin materials such as PP and PE can be used. However, when the above-mentioned APET (amorphous polyethylene terephthalate) resin is used, it is easy to recycle the waste material, and the calorific value is small even when incinerated, reducing the life of the incinerator, and harmful substances such as dioxins. This has the advantage of not causing chlorine pollution problems even when buried underground.

  Thus, the container shown in the embodiment is one in which the lowermost container is not subjected to compression deformation due to the load of the upper container at the time of stacking accommodation or stacking display. A plurality of parallel side walls 12 rising from each periphery of the bottom wall 11 and a plurality of reinforcing ribs 16 extending in a series from the peripheral portion of the opening 10 to the inner peripheral direction of the bottom wall 11 are substantially parallel to the entire side wall 12. The load-bearing performance is increased by a large number of parallel ribs 16 erected over almost the entire side wall 12.

  Further, an upper wall 13 extending in the outer peripheral direction of the side wall 12, a descending wall 14 descending downward from the outer end thereof, and an outer direction from the lower end thereof are provided at the upper end portion of each side wall 12. And the flange 15 extending to extend the deformation strength of the opening.

  On the other hand, the lid 2 also has four side walls 22 rising from the periphery of the ceiling wall 21, a stepped wall 23 extending from the upper end of the side wall 22 toward the outer periphery, and an upper side from the stepped wall 23. And a flange 25 extending from the upper end thereof toward the outer peripheral direction. Further, the four side walls 22 are formed with a number of parallel reinforcing ribs 26 extending in series from the upper end thereof to a part of the inner peripheral direction of the ceiling wall 21. Accordingly, the lid 2 also exhibits excellent strength in compressive strength and deformation strength in the central direction.

  Moreover, as shown in FIG.1 and FIG.2, the four air holes 4 arrange | positioned near each corner | angular part are formed in the ceiling wall 21 of the cover body 2, and the freshness of accommodation fruit, here cherry tomato is here. Can be maintained for a long time.

  6 and 7 show the container of the second embodiment, in which FIG. 6 is an overall perspective view and FIG. 7 is a plan view thereof.

  In the container shown in the second embodiment, the structure of the container body 1 and the structure of the lid 2 are the same as the structure of the container body 1 and the structure of the lid 2 of the first embodiment. . However, the container shown in the second embodiment is composed of two members, with the container body 1 and the lid body 2 as separate bodies. As a molding material, a 0.3 mm thick PET (polyethylene terephthalate) resin is used. Other points are in accordance with the container of the first embodiment.

  In the above description of the embodiments, the container main body, and thus the lid body, is shown as having a substantially square shape in plan view. However, the length of the other pair of sides with respect to the pair of sides is set to be twice or less than twice. It may be implemented as a rectangular shape in plan view. As a result of the experiment, if the length of the long side exceeds twice the length of the short side, deformation in the longitudinal direction on the long side easily occurs, which is not preferable.

  In carrying out the present invention, the present invention can be appropriately implemented within the scope of the above-described constituent requirements, the achievement of the above object, and the above effect.

  Uses the thinnest possible sheet material and maximizes the necessary strength in the structure, so it is useful in that it can be offered to the market at least as much as the weight of the material sheet. It is.
