Description

  The present invention relates to a food container used for a lunch box sold in a convenience store or a supermarket, for example.

  Various lunch boxes are sold at convenience stores and supermarkets (hereinafter referred to as "convenience stores"). These lunch boxes are generally sold in a plastic food container having a container body and an openable / closable lid member for closing the opening. The container body is generally divided into a plurality of compartments by a partition, and rice and a plurality of types of prepared food are stored in a state of being separated into the respective compartments (see, for example, Patent Document 1). A lunch box is handed over to the purchaser after it is manufactured, and a relatively long time (for example, several hours) elapses before the purchaser actually eats. Therefore, if food containing fluid roux and sauce such as curry and beef bowl (hereinafter referred to as “separately required food”) is placed on rice during manufacture, Curry roux and gyudon sauce are soaked in the rice and the texture and taste are lost.

  Therefore, in the case of curry and beef bowls, rice and curry are separately stored in a plurality of container bodies in the same manner as described above, and when the purchaser eats, curry or the like is placed on the rice. I try to put it on.

In addition, a technique is known in which a specific food containing liquid juice is separated by inserting a film-like sheet between other foods or by using a separate container to form two layers. Yes.
JP 2001-355199 A

  However, in the above, since the separated foods such as curry are stored separately from rice, it is necessary to increase the number of partitions by increasing the number of partitions in the container body, and accordingly, the area occupied by the container increases (the size is reduced). There was a problem of taking up space when displaying at convenience stores.

  Moreover, when a purchaser eats, the operation | movement which puts separation required foods, such as curry, on rice becomes complicated.

  Although it is possible to apply a technology that separates foods that require separation from other foods with a single film-like sheet, such as curry, in this case, when the purchaser eats the sheet, When the sheet is pulled out, one side of the sheet is exposed with the curry roux adhering to it, so that the roux may adhere to the purchaser's hands and clothes and become contaminated.

  Therefore, the present invention reduces the occupied area by reducing the partition of the container body, and when the purchaser eats, troublesome operations such as placing the food requiring separation on the rice are unnecessary, and the sheet An object of the present invention is to provide a food container that prevents contamination of hands and clothes by preventing a part of the separated food adhering to the sheet pulled out when using the bag from being exposed.

The invention according to claim 1 relates to a food container for storing food. The food container according to the present invention has an opening in the upper part, a container body in which the food is stored inside through the opening, an openable / closable lid member that closes the opening, and the container Among the foods stored in the main body, the separation required food is stored inside and separated from the other foods, and the container main body and the lid member are formed on the separation bag. A diaphragm structure that squeezes out, and the diaphragm structure is provided in the vicinity of the end of the container body and gradually increases in height toward the outside, and the lower diaphragm in the lid member an upper aperture portion of the inclined surface shape gap is narrowed between the lower stop portion toward the outside is provided as to face the upper parts, Te outer end smell of the lower diaphragm portion and the upper stop portion, before has a slit formed laterally Kifuta member, and further The diaphragm structure has an upper lip portion for reinforcing the lid along the slit at the upper edge of the slit, and has a lower lip portion arranged along the slit and extending outward at the lower edge of the slit. The separation bag has a gripping portion protruding outward from the slit, and is connected to the gripping portion and disposed in the container body to store the specific food, and at an end far from the gripping portion. A bag body provided with a squeezing port in the part, and the bag body passes through the slit between the lower throttle part and the upper throttle part when the gripping part is pulled out from the slit. In this case, the separated food in the bag body is pushed out from the squeeze port into the container body.

The invention according to claim 2 is the food container according to claim 1 , wherein the separation bag has a folded portion that is folded upward on the squeezing port side of the bag body, and from the gripping portion side of the bag body. The separation required food is stored up to the folded portion, and the folded portion is used as a temporary lid.

The invention according to claim 3 is the food container according to claim 1 or 2 , wherein the container main body and the lid member have a handle part for gripping with a hand on the opposite side to the throttle structure. It is said.

According to the invention of claim 1, when the gripping part of the separation bag is pulled by a person, the bag body containing the separated food required is squeezed between the upper squeeze part and the lower squeeze part and by the slit. Separated food is squeezed from the bag body into the container body. Here, as foods to be separated that should be separated from other foods, foods with fluid ingredients such as curry, beef bowl, Chinese rice bowl, mapo tofu, and soup are equivalent to this. For example, rice and noodles correspond to other foods. In this case, the curry or the like can be placed on the rice that has been separated so far by a simple operation of grasping the gripping portion of the separation bag and pulling the separation bag completely out of the food container. Furthermore, according to the invention of claim 1, by separating the separation bag by bending it at the upper lip and making a crease, it is possible to reliably squeeze out the separation-required food stored in the bag body.

According to the second aspect of the present invention, before the separation bag is pulled out, the folded portion serves as a lid, and it is possible to effectively prevent the separated food from leaking from the bag body. And this folding | returning part is pushed by the food required to be separated, and a folding | returning part is eliminated, when the food separation required of a bag main body is squeezed by a squeezing structure. Thereby, the separation required initial goods are squeezed out from the squeezing port.

According to the third aspect of the invention, when pulling out the separation bag with one hand, the grip portion can be grasped with the other hand, so that the separation bag can be pulled out smoothly.

Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings. In addition, in each drawing, the member etc. which attached | subjected the same code | symbol are the same structures, The duplication description about these shall be abbreviate | omitted suitably. Moreover, in each drawing, members and the like that are not necessary for the description are omitted as appropriate.

FIG. 3B is a cross-sectional view of the separation bag 30 cut along line BB in FIG. 3A and viewed from the front side. 4A to 4D are views for explaining the operation of pulling out the separation bag 30 from the food container 1.

As shown in FIG. 1, the food container 1 includes a container body 10, a lid member 20, and a separation bag 30, and the container body 10 and the lid member 20 described above have a squeezed structure. Yes.
The container body 1 is formed of thin plastic, and has a substantially rectangular bottom 11 and four sides rising obliquely from its four sides, that is, a front side 12, a left side 13, a right side 14, and a rear side. (Not shown). An opening 15 is formed in the upper part of the container body 1, and food such as rice and noodles (hereinafter referred to as “Rice etc. R”, see FIG. 2) is accommodated inside the opening 15. . On the four peripheral portions of the opening 15 (peripheral portions that are continuous with the upper ends of the four side portions described above), the engaging portions 16 that project outwardly in a flange shape and are bent downward (FIG. 2). Reference is omitted in FIG. 1). The engaging portion 16 is configured such that an engaging portion 26 of the lid member 20 to be described later is attached and detached by snap fitting so that the lid member 20 can be opened and closed. As shown in FIG. 1, a portion of the engaging portion 16 located on the side opposite to the diaphragm structure 40 described later (a portion positioned on the left side in FIG. 1) is on the lid member 20 side described later. A handle portion 27 is formed together with the joint portion 26.

  The lid member 20 is formed of a thin and transparent plastic, and has a substantially rectangular top portion 21 and four side portions obliquely suspended from four sides thereof, that is, a front side portion 22, a left side portion 23, and a right side portion 24. And a rear side (not shown). In the lower part of the lid member, an opening 25 that matches the opening 15 in the container body 10 is formed. Engaging portions 26 (see FIG. 2, not shown in FIG. 1) are formed on the four peripheral portions of the opening 25 (peripheral portions that are continuous with the lower ends of the four side portions described above). The engaging portion 26 has a folded-back portion 26a that protrudes outwardly in a flange shape, has a peripheral edge bent downward, and is further folded inwardly to be hooked on the lower end of the engaging portion 16 of the container body 10 described above. ing. The engaging part 26 is attached to and detached from the above-described engaging part 26 on the container body 10 side by snap fit. The lid member 20 does not easily disengage from the container body 10 in a state in which the engagement part 26 is engaged with the engagement part 16 on the container body 10 side, but the lid member 20 is actively opened. On the other hand, the engagement can be released relatively easily.

  As shown in FIG. 3, the separation bag 30 is formed of a transparent bag. The separation bag 30 has a bag body 31 at the center in the left-right direction (the center in the left-right direction in FIGS. 3A and 3B), and a gripping portion 33 is provided on the right end side thereof. On the side, a folded portion 32 is provided. The bag body 31 is formed by stacking two sheets, that is, an upper sheet 31a and a lower sheet 31b, and has a front end side and a rear end side closed, and a right end side closed connection portion. The holding part 33 is connected via 31c. A folded portion 32 is connected to the left end side of the bag body 31 through a fold line 31d. The folded portion is formed in a cylindrical shape, and in a state where the fold line 31d is extended, the squeezing port 32a opened to the leftmost end side is located on the leftmost side of the bag body 31 as it is. ing. In other words, it can be said that the folded portion 32 is formed by folding the opening side of the bag-shaped bag body 31 upward by the fold line 31d. Therefore, the folded portion 32 is integrally continuous with the left end side of the bag body 31 in a state where the fold line 31d is extended. The bag body 31 stores separated food G (a food containing fluid roux and sauce such as curry and beef bowl). Then, when the separated food G is stored in the bag body 31, when the folded portion 32 is formed by folding at the fold 31d, the folded food 32 is almost sealed by the fold 31d and the separated food G does not leak. As shown in FIG. 3, the separation bag 30 includes the bag body 31 and the folded portion 32 in a state where the separated food G is stored in the bag body 31 and folded at the fold line 31 d to form the folded portion 32. 2, as shown in FIG. 4, it is accommodated inside the container body 10 in a state of being closed by the lid member 20 and placed on the rice or the like R. At this time, the holding part 33 which continues through the connection part 31c on the right end side of the bag body 31 is in a state of being pulled out from a slit 44 described later. In addition, when the foodstuffs G to be separated do not have fluidity, the bag body 31 is not necessarily limited to a bag shape in which only one is opened. For example, in addition to the one opening, the front end side Further, the rear end side may also be opened, and the separated food G may be sandwiched between the upper sheet 31a and the lower sheet 31b that are open on the three sides.

  As shown in FIGS. 1 and 2, the throttle structure 40 is provided on the right side portions 14 and 24 of the container body 10 and the lid member 20. The diaphragm structure 40 includes a first upper diaphragm part (upper diaphragm part) 41a, a second upper diaphragm part (upper diaphragm part) 42a, an upper lip part 43a, a slit 44, and a lower lip part formed on the right side 24 of the lid member 20. 43b, and a first lower throttle part (lower throttle part) 41b and a second lower throttle part (lower throttle part) 42b formed on the right side part 14 of the container main body 10, both of which are container main bodies. 10 and the right side portions 14 and 24 of the lid member 20 are provided over almost the entire length.

  The first upper restricting portion 41a on the lid member 20 side is provided continuously to the right end edge of the top portion 21, and is formed on an inclined surface positioned downward on the outer side. The upper aperture portion 42a is continuous as a gently inclined surface. The upper lip portion 43a is formed thicker at the right end edge of the second upper restricting portion 42a than the other portions, and reinforces the right end edge. A curved lower lip portion 43b is formed in a step shape that is thicker than other portions so as to extend obliquely downward, slightly below the right side of the upper lip portion 43a, and between the upper lip portion 43a and the lower lip portion 43b. A slit 44 long in the front-rear direction is formed. From the slit 44, the gripping portion 33 of the separation bag 30 is projected outward. The first lower throttle part 41b on the container body 10 side is disposed opposite to the lower side of the first upper throttle part 41a on the lid member 20 side, and is provided continuously to the right edge of the bottom part 11. It is formed in the inclined surface located upwards, so that the outer side. On the right end side of the first upper aperture portion 41b, a second lower aperture portion 42b is arranged so as to face the lower side of the second upper aperture portion 42a on the lid member 20 side.

  As described above, in the diaphragm mechanism 40, the first upper diaphragm portion 41a and the first lower diaphragm portion 41b are arranged so as to face each other in the vertical direction, and the distance between the two is set to be narrower toward the outside. . In addition, the second upper diaphragm portion 42a that is continuous with the first upper diaphragm portion 41a and the second lower diaphragm portion 42b that is continuous with the first lower diaphragm portion 41b are arranged so as to face each other in the vertical direction. The gap is set to be narrower toward the outside. The gap of the slit 44 between the upper lip 43a and the lower lip 43b is set to be further narrowed. That is, the upper lip portion 43a and the lower lip portion 43b have a final aperture function. 2, the upper lip portion 43a and the lower lip portion 43b are formed in a step shape, and a slit 44 is provided at the boundary portion, for example, the lid member 20 is formed by injection molding. The shape of a mold (not shown) used in manufacturing can be simplified, and the strength of the portion corresponding to the slit 44 of the mold can be increased. Further, as shown in FIG. 2, a part of the throttle structure 40 is formed on a part of the engaging part 16 of the container body 10 and a part of the engaging part 26 of the lid member 20. May reduce the bonding force between the container body 10 and the lid member 20, but as described above, the lower lip portion 43b is formed into a curved surface, thereby increasing the strength and reducing the bonding force. I try to prevent it. Note that the upper lip portion 43a and the lower lip portion 43b do not need to be particularly thicker than the other portions constituting the lid member 20 if the necessary strength can be ensured by forming the upper lip portion 43a and the lower lip portion 43b.

  With reference to Fig.4 (a)-(d), operation | movement of the separation bag 30 in the food container 1 is demonstrated.

  As shown in (a), the purchaser holds the gripping portion 33 of the separation bag 30 protruding from the slit 44 with his hand, lifts it in the direction of the arrow K1, and holds it at the position indicated by the two-dot chain line. As a result, the separation bag 30 is bent at the tip of the upper lip portion 43a, so that a stronger squeezing can be performed. When the purchaser pulls the gripping part 33 in the direction of the arrow K2, as shown in (b), the separation required food G stored in the bag body 31 of the separation bag 30 is separated from the first upper squeezing part 41a and the first lower part. The gap is gradually narrowed and effectively narrowed by the slit 44 between the narrowed portion 41b and between the second upper narrowed portion 42a and the second lower narrowed portion 42b. Thereby, the folding | returning part 32 of the separation bag 30 is extended to the left, and the separation required food G is squeezed out from the opening part 32a, and is mounted on rice etc. R. Further, as shown in (c) and (d), when the grip portion 33 is pulled, the separated food G that is required to be squeezed out from the bag body 31 is placed over the entire upper surface of the rice or the like R.

As described above, according to the present embodiment, the bag body 31 that stores the separation-required food G such as curry is formed into the upper squeezing portion (first upper squeezed portion) by pulling the gripping portion 33 of the separation bag 30 by the person. Since it is squeezed between the portion 41a, the second upper squeezed portion 42a) and the lower squeezed portion (the first lower squeezed portion 41b, the second lower squeezed portion 42b), and by the slit 44, the separated food G required from the bag body 31 It is squeezed out on the rice or the like R in the container body 10. In other words, by holding the grip 33 of the separation bag 30 and pulling the separation bag 30 completely out of the food container, the separation-required food G such as curry is placed on the rice R that has been separated until then. Can be placed. For this reason, the space for providing separately the separated food G required is unnecessary, and the occupation area of the food container 1 can be made small. In addition, when the separated food G such as curry has been separated into different sections as in the prior art, it is necessary to place the separated food G on the rice or the like R in a separate operation, which is complicated. However, such complicated work can be omitted. Furthermore, since the part which the part (for example, curry roux) of the separation required food G adheres does not expose the separation bag 30 after drawing, there is no possibility of contaminating hands and clothes. Further, since the slit 44 is provided between the reinforced upper lip portion 43a and the lower lip portion 43b, when the separation bag 30 is pulled out, the separation bag 30 is bent at the tip of the upper lip portion 43a. Since the drawing can be performed, the drawing can be performed more strongly.
