Description

  For example, in various lunch boxes sold in stores such as convenience stores, supermarkets, etc., when making it possible to purchase any combination of cooked rice as a staple food and various side dishes as a side ingredient in a predetermined container, By covering each container with a common lid, it is easy to handle each display and sale in the store, and the containers that contain purchased rice and prepared dishes can be combined up and down after purchase. The present invention relates to a two-stage fitting type food container that can be easily carried when a combination of the upper and lower parts is purchased and carried by the reliable overlapping of the containers.

  In the past, especially so-called prepared food markets where lunches that combine cooked prepared dishes and cooked rice are sold at convenience stores, supermarkets, etc. have been attracting attention. Various food containers that take into account are provided. However, a bento box that contains a combination of cooked rice and various side dishes in one container not only narrows the range of choice by the purchaser, but also may not be able to accommodate each person's preference, the amount of cooked rice, and the like. In order to solve this problem, a rice container containing rice and a side dish container containing various side dishes are prepared separately and can be purchased in any combination thereof. It was not easy to fix when stacking, and it was cumbersome to carry together after purchase.

  For these reasons, as food containers and packaging containers using containers of this type, for example, conventionally, for example, a packaging container in Patent Document 1, a container with dish serving in Patent Document 2, and Patent Document 3 A lunch box, etc., has been proposed. In the packaging container of Patent Document 1, the upper container body is fitted and held on the peripheral flange portion of the lower container body, and the periphery of the lid that covers the upper container body is engaged with the periphery of the lower container body. Let's hold together. The dish serving container of Patent Document 2 is provided with a step portion for engaging the upper partition container inside the peripheral wall of the outer container, and the upper lower partition container is provided with a protrusion capable of supporting the upper partition container. In the lunch box of Patent Document 3, an upper container that is stacked up and down, a waterproof inner container that is fitted in each of the lower containers, and the waterproof inner container are stacked on each of the upper container and the lower container. Also, any combination is possible.

Japanese Patent Laid-Open No. 10-245054 JP 2005-111065 A Registered Utility Model No. 3028198

  However, according to the packaging container of Patent Document 1, the lid placed on the upper container body that is overlapped and fitted on the lower container body is engaged and held by the lower container body. It is difficult to use the container body alone by simply covering the container body with a lid. According to the dish-filled container of Patent Document 2, since the upper and lower partition containers stacked in the outer container are used while being covered with a lid, this is also the same as the packaging container of Patent Document 1. It is still difficult to use the container alone. In the lunch box of Patent Document 3, the waterproof inner container is arbitrarily combined with the upper container or the lower container and overlapped in the upper and lower directions, so that the use of each of them is not considered.

  That is, in the conventional containers as described above, even if they are scheduled to be overlapped from the beginning, each container to be combined is not used separately. Therefore, for example, in a convenience store, a supermarket, etc. It is not suitable to be used in the selective / combination sales method that purchases a combination and superimposes them up and down to make a bento.

Therefore, the present invention was devised in view of the above-described circumstances, and the purpose thereof is, for example, to store and sell the main foods such as cooked rice and various foods as side foods in separate containers. In this case, the opening of each of these containers can be covered with a common lid so that the purchase at the time of display sale can meet various needs by arbitrarily combining the purchase according to the purchaser's preference. In addition, even when various kinds of cooked rice are provided later in the container according to the order, or a combination of containers containing cooked rice and various side dishes is provided, these can be combined at the top and bottom. The object is to propose a two-stage food fitting container that is compact and easy to carry when taken home.

An object of the present invention is to provide a two-stage fitting type food container that can be easily carried by fitting in a stable state when different containers purchased by arbitrarily selecting and combining are stacked one above the other.

In order to solve the above-described problems, in the present invention, a description will be given with reference numerals in the form for carrying out the invention to be described later, and gradually expanded outward from the bottom wall 2 to the opening. A lower lid 1 having a lower lid flange 4 formed at the opening, and a support step 5 at the inner periphery of the opening, and an opening from the bottom wall 12. The side wall 13 is inclined so as to gradually expand outward, the upper lid flange 14 is formed in the opening, and the outer shape of the bottom wall 12 as the bottom is the opening of the lower container 1. The upper container 11 that is locked to the support step 5 and the lid 20 having the same structure that is commonly applied to the openings of the lower container 1 and the upper container 11. It is characterized by comprising.
The outer width of the lower lid flange 4 of the lower container 1 is formed to be the same width as the outer width of the upper lid flange 14 of the upper container 11, and the lid 20 is an opening of each of the lower container 1 and the upper container 11. The parts can be commonly fitted from the outside and covered so that they can be covered.
The width W1 of the lower lid flange 4 is configured by setting the width W2 of the upper lid flange 14 of the upper container 11 and the width difference W3 between the opening and the bottom of the inclined side wall 13 of the upper container 11 to a total width. can do.
The bottom outer peripheral edge of the upper container 11 and the inner peripheral edge of the opening of the lower container 1 are fitted to each other when the bottom part of the upper container 11 is engaged with the support step 5 of the lower container 1. It can be configured by providing the fitting means 10 by the male and female concave and convex portions 10a and 10b in the shape of small protrusions.
The inclination angles of the side wall 3 of the lower container 1 and the side wall 13 of the upper container 11 are the same, and when the upper container 11 is overlapped and fitted to the lower container 1, the side wall 13 of the upper container 11 and the lower container 1 are aligned. The side wall 3 of the upper container 11 is tapered in a straight line when viewed from the side. The width at the opening of the upper container 11, the outer width at the bottom of the upper container 11, and the inner method at the opening of the lower container 1. The width and the width at the bottom of the lower container 1 can be formed by sequentially forming a narrow width.

In the two-stage fitting type food container according to the present invention configured as described above, each of the lower container 1 and the upper container 11 stacked in the upper and lower stages accommodates, for example, cooked rice R, various prepared foods S, etc. By selling for display, these purchasers are allowed to increase the range of selection of the combinations, for example, to make it possible to meet various needs of purchasers as various types of lunch boxes. Moreover, even if it is the lower container 1 and the upper container 11 which can be overlap | superposed in a fitting type, these opening parts can be covered with the cover body 20 of a common shape and structure, and these three parts are used by a total of three types of members. Easy material management.
Since the outer width of each of the lower lid flange 4 of the lower container 1 and the upper lid flange 14 of the upper container 11 is the same, the lid is covered by being fitted to the lower lid flange 4 and the upper lid flange 14 from the outside. The body 20 can be used in common, and it is possible to select a usage pattern having a different pattern with a combination of a small number of members.
The support container 5 in the lower container 1 supports the upper container 11 that is fitted and overlapped with the lower container 1 by the opening of the lower container 1, and the upper container 11 is covered by a lid 20 that covers the opening of the lower container 1. It is placed and supported, and can be easily carried by stacking in a stable state on the top and bottom.
The fitting means 10 by the concavo-convex parts 10a and 10b of the small protrusions is engaged with the supporting step part 5 of the lower container 1 so that the upper container 11 is overlapped and placed in the opening of the lower container 1. Tightly coupled to further increase stability when mated.
Each of the inclined side wall 3 in the lower container 1 and the inclined side wall 13 in the upper container 11 is a straight taper that is continuous when viewed from the side at the time of overlapping, and the inclination angle is the same. The container 1 can be accommodated in the upper container 11 and is compactly packed when not in use.

  Since this device is configured as described above, for example, rice R as a staple food and various side dishes S as a side food can be separately stored and sold in the lower container 1 and the upper container 11 and purchased by the purchaser. When they are selected and appropriately combined to form separate containers that have a bento structure according to preference, the openings of the lower container 1 and the upper container 11 can be covered by a common lid 20. That is, the lower container 1 and the upper container 11 having different opening structures can be covered by one type of lid body 20 because they can be fitted and overlapped vertically. In addition, various kinds of cooked rice R and various side dishes S are accommodated and displayed in the lower container 1 and the upper container 11, respectively, thereby enabling the purchaser to make various selections and responding to various needs according to the purchaser's preference. it can. In addition, when various kinds of cooked rice R are accommodated in the lower container 1 according to an order and the upper container 11 containing various prepared foods S is provided in an overlapping manner, or the lower container containing the cooked rice R and various prepared foods S. 1. Even when a lunch box is provided in which the upper container 11 is combined, it is compact and easy to carry when taken home such as when combined in the upper and lower directions. Moreover, the upper container 11 can be directly overlapped with the lower container 1 with or without the lid 20 so that a lunch box container combined in two stages can be obtained. It is stable and can be easily carried around.

  That is, in the present invention, this is a lower container comprising a bottom wall 2, an inclined side wall 3 that expands outward, a lower lid flange 4 of the opening, and a support step 5 on the inner periphery of the opening. 1, an upper container 11 having a bottom wall 12, an inclined side wall 13 that expands outward, and an upper lid flange 14 of an opening, and the outer shape of the bottom is locked to the support step 5 of the lower container 1. This is because it includes a lid 20 having the same structure that is commonly applied to the openings of the lower container 1 and the upper container 11. As a result, the different opening structures in the lower container 1 and the upper container 11 can be covered with a single type of lid body 20 so that they can be overlapped with each other, and handling by combining the respective members is easy. Can be. In addition, the upper container 11 can be placed on or placed on the lower container 1 that is covered or not covered by the lid body 20, and can be stacked up and down, and the lower container 1 or the upper container 11 can be stacked. For example, it can be made into a two-stage lunch box with various combinations of rice R and various side dishes S.

  Further, even if the side wall 3 of the lower container 1 and the side wall 13 of the upper container 11 are inclined, the inner width of the opening of the lower container 1 is smaller than the inner width of the opening of the upper container 11, The width W1 of the lower lid flange 4 itself of the lower container 1 is the total width of the width W2 of the upper lid flange 14 of the upper container 11 and the width difference W3 between the opening and the bottom of the inclined side wall 13 of the upper container 11. Therefore, the outer width of the opening of the lower container 1 can be made substantially the same as the outer width of the opening of the upper container 11.

  As a result, the outer widths of the lower lid flange 4 of the lower container 1 and the upper lid flange 14 of the upper container 11 are formed to have the same width, so that the lid 20 is an opening of each of the lower container 1 and the upper container 11. It is possible to cover by covering from the outside in common, and it is not necessary to prepare different different lid members corresponding to the lower container 1 and the upper container 11 respectively.

  Moreover, since the fitting means 10 is provided by the male and female concave and convex portions 10a and 10b in the shape of small protrusions that are fitted together between the outer peripheral edge of the bottom of the upper container 11 and the inner peripheral edge of the opening of the lower container 1. When the bottom of the upper container 11 is fitted into the opening of the lower container 1, the upper container 11 is supported on the support container 5 of the lower container 1, and the upper container 11 The container 11 can be firmly fitted and supported. Furthermore, in the overlapped state, the fitted state does not come off due to external impact, the tilt when overlapped, etc. You can carry it with your heart.

  Further, the inclination angles of the side wall 3 of the lower container 1 and the side wall 13 of the upper container 11 are the same, and when they are stacked one above the other, they form a taper shape that is continuous in a straight line when viewed from the side, and at the opening of the upper container 11 The width, the outer width at the bottom of the upper container 11, the inner width at the opening of the lower container 1, and the width at the bottom of the lower container 1 are sequentially formed to be narrow, and the lower container 1 is not used when not in use. There is also an advantage that the upper container 11 can be accommodated and can be collected in a compact manner.

  In addition, the code | symbol attached | subjected in each of the means for solving said subject, and the item of the effect of an invention was attached | subjected in order to make easy reference with the part which shows each structure part described in drawing. The present invention is not limited to the structure and shape shown by these descriptions and reference numerals in the drawings.

It is a disassembled perspective view which shows one form for implementing this device. It is a front sectional view when similarly superposed. It is a front sectional view when similarly covering the lower container. It is a principal part plane sectional view explaining each of the fitting structure of the overlapping part, and the steam vent groove structure when they are similarly overlapped.

Similarly, it is a perspective view when overlapping and sealing with a binding tool.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment for carrying out the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the figure is a lower container positioned at the lower stage when stacked one on top of the other. For example, it is formed in, for example, a flat rectangular shape having a predetermined depth with a volume that can accommodate a predetermined amount of, for example, cooked rice R for one meal that is a staple food.

  The lower container 1 itself has a side wall 3 that is inclined so as to gradually expand outward from the bottom wall 2 to the opening, and a lower lid flange 4 that also serves as a reinforcement of the lower container 1 itself is formed in the opening. A support step portion 5 is provided on the inner periphery of the opening to support an upper container 11 to be described later by fitting in an inner fitting manner. The side wall 3 is appropriately provided with a plurality of reinforcing grooves having a groove shape along the vertical direction. In addition, the predetermined shallow bottom-shaped reinforcement part 9 which protruded below is formed in the periphery of the bottom wall 2 of the lower container 1 in illustration.

  In the figure, reference numeral 8 denotes a vapor vent groove formed in a narrow groove shape on the upper side of the support step 5 which is the inner peripheral edge of the opening of the lower container 1. As will be described later, when the upper container 11 is locked on the support step part 5 of the lower container 1 and is fitted and overlapped, a groove-like gap is formed between the upper container 11 and the bottom part. Thus, when the upper container 11 is fitted in the lower container 1 and heated by, for example, a microwave oven in a superposed state, the vapor filled in the lower container 1 is guided and released to the outside (see FIG. 4).

  An upper container 11 that can be superposed on the lower container 1 is provided separately, and the upper container 11 has a predetermined depth with a volume that can accommodate a predetermined amount of, for example, various kinds of prepared food S that are by-products. For example, it is formed in a flat rectangular shape having a thickness and is fitted to the lower container 1 in a state where it is placed and supported by being locked to the support step 5 formed in the opening of the upper container 1. It is supposed to be.

  Similar to the lower container 1, the upper container 11 itself has a side wall 13 that is inclined so as to gradually expand outward from the bottom wall 12 to the opening, and the opening is used to reinforce the upper container 11 itself. The upper lid flange 14 is also formed. A predetermined shallow bottom-shaped reinforcing portion 19 that protrudes downward is provided at the periphery of the bottom wall 12, and the side wall 13 has a plurality of reinforcing grooves that have a groove shape along the vertical direction. Are provided as appropriate.

  The outer shape of the bottom wall 12 that is the bottom of the upper container 11 corresponds to the inner shape of the opening of the lower container 1, and the bottom of the upper container 11 fits into the opening of the lower container 1. Also, as shown in FIG. 4, by the male and female uneven portions 10a and 10b fitted together between the bottom outer peripheral edge of the upper container 11 and the inner peripheral edge of the opening of the lower container 1 when fitted. A fitting means 10 is provided. In the figure, the projections are curved, and the concavo-convex portions 10a and 10b of the upper container 11 and the lower container 1 are both formed so as to travel outward. May be formed.

  Further, when the upper container 11 is overlapped and fitted on the lower container 1, the side wall 13 of the upper container 11 and the side wall 3 of the lower container 1 have the same inclination angle when viewed from the side as shown in FIG. As a result, it is as if the taper shape is continuous in a straight line. That is, the width at the opening of the upper container 11, the outer width at the bottom of the upper container 11, the inner width at the opening of the lower container 1, and the width at the bottom of the lower container 1 are successively narrowed. By doing so, the lower container 1 can be completely stored and accommodated in the upper container 11 and can be compactly packed when not used or not used, such as cooked rice R and various prepared foods S.

  As shown in FIG. 5, the outer width of the lower lid flange 4 formed in the opening in the lower container 1 is the same as the outer width of the upper lid flange 14 formed in the opening in the upper container 11. The width W1 of the lower lid flange 4 itself is formed wider than the width W2 of the upper lid flange 14 itself. That is, the width W1 of the lower lid flange 4 is set to the total width of the width W2 of the upper lid flange 14 of the upper container 11 and the width difference W3 between the opening and the bottom of the tapered side wall 13 of the upper container 11. By doing so, the outer width of each of the lower lid flange 4 and the upper lid flange 14 can be made the same.

  Each of the lower container 1 and the upper container 11 is covered with a common lid 20 having the same structure and shape. The lid 20 includes inner peripheral edges corresponding to the outer peripheral edges of the lower lid flange 4 and the upper lid flange 14 which are openings of the lower container 1 and the upper container 11, respectively. It is formed in the shape of a reverse shallow bottom dome that is fitted from the outside so as to cover the opening.

  As described above, the width of each of the outer shapes of the lower lid flange 4 of the lower container 1 and the outer shape of the upper lid flange 14 of the upper container 11 is the same as the width of the lower container 1. The container 11 can be used in common. Therefore, for example, the lower container 1 in which the cooked rice R is accommodated and the upper container 11 in which the various side dishes S are accommodated can be covered, and when the upper container 11 is fitted into the lower container 1 and stacked, It should be used so as to cover only the opening.

  On the upper wall of the lid 20, a bottom fitting portion 21 is formed so as to bulge out around the bottom portion so as to fit and surround the bottom portion of the upper container 11. By doing so, although not shown in the drawing, it is possible to prevent positional displacement when the upper container 11 is placed on the lid body 20 that is applied to the opening of the lower container 1, and to realize a stable overlapping state.

  Moreover, as shown in FIG. 6, the lower container 1 and the upper container 11 are overlapped, and, for example, a wide tape-like bundling made of a synthetic resin film is fixed in the vertical direction when the upper container 11 is covered with the lid 20. The lower container 1, the upper container 11, and the lid body 20 may be wound by the tool 25. A positioning insertion portion 22 is formed at a symmetrical position on the upper wall of the lid 20 so as to prevent such positional deviation of the binding tool 25 when being wound and fixed, and the positioning insertion portion 22 is formed on the lower container 1. The insertion portions formed in the shape of depressions in the reinforcing portions 9 and 19 at the bottom of the upper container 11 are configured so that their positions substantially coincide with each other in the vertical direction.

  When the upper container 11 is overlapped with the lower container 1, the upper container 11 is placed by covering the opening of the lower container 1 with the lid 20, but the lower container 1 is covered with the lid 20. Without overlapping, the upper container 11 may be directly superposed on the support step part 5 of the lower container 1 and may be superposed, both of which are optional.

  In addition, although the lower container 1, the upper container 11 and the like in the illustrated example are configured and described as having a rectangular shape in a plane, they are assumed to have a circular shape, a hexagonal shape, an octagonal shape, or other polygonal shapes in the plane. It is also possible to configure.

  Next, an example of use by the combination of the lower container 1, the upper container 11, and the lid 20 will be described. For example, various kinds of cooked rice R are mainly contained in the lower container 1, and various foods that are sub-foods in the upper container 11. When the side dishes S are accommodated, and are displayed and sold in, for example, convenience stores, supermarkets, etc. in a state where they are covered by the lid 20 having the same structure common to the lower container 1 and the upper container 11, For example, the purchase by arbitrary combinations is enabled. For example, cooked rice R with different types of rice cake, mixed rice, etc., as well as various types of prepared meals with different types of salad, Japanese and Western dishes, etc. The selection and combination will be expanded to meet various needs.

  In addition, various cooked rice R is stored in the lower container 1 according to the individual order of the customer to be purchased, and is provided as various one lunches that can be combined by overlapping the upper container 11 in which various prepared foods S are stored. Further, the lower container 1 containing the cooked rice R and the upper container 11 containing the various side dishes S may be provided and sold as various lunch boxes by combining them in advance in various ways.

  In addition, after purchase, the upper container 11 is fitted into the opening of the lower container 1 that is not covered and stacked, or the upper container 11 is placed and stacked on the lower container 1 covered by the lid 20. In a superposed state, it is stable without causing a positional shift in the vertical direction, so that even if it is housed and carried, for example, in a so-called shopping bag, it is less likely to fall down and can be easily carried. Of course, it can be made more stable by binding in the vertical direction by the binding tool 25.
