FIG. 9 is an enlarged perspective view showing a state in which the flap portion 30 is opened. As shown in FIGS. 4 and 5, the lid body 2 includes a plate-like main body portion 20 for covering the opening S <b> 1 of the container main body 1, a flap portion 30 disposed on the upper surface side of the main body portion 20, and vice versa. And a seal portion 40 disposed on the lower surface side of the main body portion 20 on the side. Hereinafter, these parts will be described in detail.

  The main body portion 20 includes a flat plate member 21 having arcuate corners and a rectangular shape as a whole, and an annular outer peripheral portion 22 that is continuous with the outer peripheral edge of the flat plate member 21. The outer peripheral portion 22 bulges upward from the flat plate member 21 over its entire circumference. More specifically, as shown in FIGS. 6 and 7, the outer peripheral portion 22 includes an annular inner wall portion 22a that protrudes upward and outward from the flat plate member 21, and an annular inner wall portion 22a that extends in the horizontal direction outward from the upper end of the inner wall portion 22a. It has a top surface portion 22b and an annular outer wall portion 22c extending downward from the outer peripheral edge of the top surface portion 22b. Accordingly, an annular groove S2 is formed on the lower surface side of the outer peripheral portion 22 facing the internal space of the container body 1, and an annular seal portion 40 is disposed in the annular groove S2.

  The seal part 40 is a member that functions as a so-called packing, and is in close contact with the peripheral edge 1 a of the container body 1 so as to seal the opening S <b> 1 of the container body 1 when the lid 2 is attached to the container body 1. Therefore, the main body 20 in the present embodiment is integrally formed of a hard resin material such as polypropylene or saturated polyester, but the seal portion 40 is integrally formed of a softer elastic material such as rubber or elastomer. Molded. That is, the main body portion 20 and the seal portion 40 are made of different materials, but as will be described in detail below, the seal portion 40 is integrated with the lower surface of the outer peripheral portion 22 of the main body portion 20. Therefore, there is no gap for water or dirt to enter between the seal portion 40 and the main body portion 20. In addition, the main body 20 and the seal 40 in the present embodiment have heat resistance and cold resistance, similar to the container main body 1. However, in other embodiments, the material constituting the main body portion 20 and the seal portion 40 is not limited to those described above. For example, if the use of a microwave oven is disabled, the material does not have heat resistance. Alternatively, the main body 20 may be made of metal.

  As shown in FIGS. 6 and 7, an annular groove S <b> 3 for receiving the peripheral edge portion 1 a at the upper end of the container body 1 is formed on the lower surface of the seal portion 40. More specifically, the seal part 40 has an inverted U-shaped inner part 40a and a U-shaped outer part 40b continuous to the outside of the inner part 40a in a longitudinal sectional view. And the groove | channel formed along the circumferential direction by the inner side part 40a of the above shapes turns into the annular groove S3. The inner part 40a is integrated with the top surface part 22b and the outer wall part 22c of the main body part 20 without a gap. Further, an outer wall portion 22c of the main body portion 20 is disposed in a groove formed along the circumferential direction by the outer portion 40b, and both the members 40b and 22c are integrated with no gap in the groove. Moreover, as shown in FIGS. 6-8, the outermost surface of the outer side part 40b of the seal | sticker part 40 and the outermost surface of the outer wall part 22c of the main-body part 20 are formed so that it may become substantially flush. Therefore, the lid body 2 has less unevenness in appearance and is excellent in design in this respect.

  A slit S4 (see FIG. 8) extending in the width direction is formed on the top surface portion 22b of the outer peripheral portion 22 of the main body portion 20 in the vicinity of the center of the portion corresponding to one side extending in the width direction of the outer peripheral portion 22. And the flap part 30 protrudes from the inner side part 40a of the seal | sticker part 40 to the upper surface side of the main-body part 20 through this slit S4. The flap part 30 is integrally formed of the same material as the seal part 40. In addition, the flap part 30 is integrated without a gap with respect to the surface that defines the slit S4 in the top surface part 22b of the main body part 20.

  As shown in FIGS. 8 and 9, the flap portion 30 is a plate-like member having a substantially uniform thickness, but the width of the flap portion 30 at a position immediately after extending from the seal portion 40 and exiting the slit S <b> 4. It is formed thin in the entire direction. Accordingly, when a force in an appropriate direction is applied by the user, the flap portion 30 can be bent by the elastic hinge with respect to the outer peripheral portion 22 at the base with the thin portion as a rotation axis. In FIG. 8, the flap part 30 in a bent state is shown by a solid line, and the flap part 30 in a state extending in a straight line in the vertical direction is shown by a two-dot chain line.

  The flat plate member 21 surrounded by the outer peripheral portion 22 is recessed below the top surface portion 22 b of the outer peripheral portion 22, but in the vicinity of the flap portion 30, it bulges upward from the flat plate member 21 instead of the flat plate member 21. A horizontal plane portion 23 exists. The horizontal surface portion 23 is a part of the main body portion 20, and the flat plate member 21 and the horizontal surface portion 23 are continuous. The horizontal surface portion 23 is configured to closely contact the flap portion 30 on the surface when the flap portion 30 rotates around the thin portion at the base and falls horizontally. At this time, the upper surface of the flap part 30 and the upper surface of the top surface part 22b of the outer peripheral part 22 are formed to be substantially flush with each other. Therefore, the lid body 2 has less unevenness in appearance and is excellent in design in this respect.

  The height of the leg portion 15 provided on the bottom surface portion 11 of the container body 1 is configured to be equal to or greater than the sum of the height difference between the horizontal surface portion 23 and the planar member 21 and the thickness of the flap portion 30. Has been. This is because when the plurality of containers 100 are stacked one above the other, the upper container body 1 is lifted by the presence of the horizontal surface portion 23 and the flap portion 30 and does not fall off from the lid 2 of the lower container 100. Moreover, the tall outer peripheral part 22 surrounding the flat plate member 21 also prevents the upper container 100 from falling off.

  The horizontal plane portion 23 is formed with a vent S5 for communicating the inside and outside of the container body 1. On the other hand, the flap portion 30 is formed with a plug body 30a having substantially the same shape as the vent hole S5. The plug body 30a passes through when the flap portion 30 falls horizontally toward the horizontal plane portion 23. It is arranged at a position such that it is inserted into the pore S5. The plug 30a in the present embodiment is formed of the same soft elastic material such as rubber or elastomer integrally with the flap portion 30. Accordingly, the plug body 30a is elastically deformed when inserted into the vent hole S5, whereby the vent hole S5 is firmly and airtightly closed. In addition, when the air hole S5 is in an open state in which the plug body 30a of the flap portion 30 is not inserted, the steam inside the container 100 is appropriately released to the outside during heating in the microwave, or conversely, the refrigerator This is useful for eliminating the negative pressure in the container 100 that is generated when the container is cooled. On the other hand, in the closed state in which the plug 30a is inserted into the vent hole S5, the food can be airtightly confined in the container 100, and the freshness of the food can be protected or the food can be prevented from leaking to the outside. .

  In addition, the lid body 2 has plate-like fixing portions 50 respectively connected to the four sides of the outer peripheral portion 22 of the main body portion 20. The fixing portion 50 is a member for fixing the lid body 2 to the side wall portion 12 of the container body 1 in order to improve the adhesion between the lid body 2 and the container body 1. The fixing part 50 is integrally formed of the same material as that of the main body part 20. As shown in FIGS. 4 and 5, the fixed portion 50 has a certain length along the outer peripheral portion 22, but is divided into two portions at both ends in the length direction, and the outer wall portion 22 c of the outer peripheral portion 22. It is connected to. The fixing portion 50 has a substantially uniform thickness, but is formed thin in the vicinity of the two connecting portions 51 and 52 with the outer wall portion 22c over the entire length direction of the connecting portions 51 and 52. Therefore, when a force in an appropriate direction is applied by the user, the fixing portion 50 can be bent by an elastic hinge with respect to the outer wall portion 22c at the root, with this thin portion as a rotation axis. 6-8, the fixed part 50 in the bent state is indicated by a solid line, and the fixed part 50 in a state extending in a straight line in the horizontal direction is indicated by a two-dot chain line.

  A space S <b> 6 is formed between the two connection portions 51 and 52 of each fixing portion 50. Of the four fixed portions 50, two fixed portions 50 (hereinafter referred to as reference numerals 50 a) connected to the sides extending in the width direction of the outer peripheral portion 22 attach the lid 2 to the container body 1. In this state, the space S6 and the grip portion 14 of the container body 1 are arranged so as to be aligned. That is, the gripping part 14 is accommodated in the space S6 when the fixing part 50a rotates around the thin part at the base and stands up and down. Therefore, the presence of the gripping portion 14 does not hinder the rotation of the fixed portion 50.

  In addition, the fixing portion 50 is formed with a hook portion 53 that extends by substantially the same width as the connection portions 51 and 52 with a certain interval in a direction away from the connection portions 51 and 52. The hook portion 53 has an L-shape in a longitudinal sectional view, and more specifically, extends inward from the plate-shaped main body of the fixing portion 50 in the state indicated by the solid line in FIGS. 6 and 7. After that, the main body 20 extends upward. The hook portion 53 is hooked on the protrusion 13a of the flange portion 13 located on the side wall portion 12 of the container body 1 when the fixing portion 50a rotates around the thin portion at the base and stands up and down. . Accordingly, when the fixing portion 50 stands up and down, the hook portion 53 and the flange portion 13 (including the protrusion 13a) of the container body 1 are elastically deformed, and the hook portion 53 is locked to the protrusion 13a. Conversely, when the lock is released, the hook portion 53 and the flange portion 13 (including the protrusion 13a) are elastically deformed, and the hook portion 53 is detached from the protrusion 13a of the container body 1.

  Moreover, the main-body part 20 and the fixing | fixed part 50 in this embodiment are formed transparently or semi-transparently, and the flap part 30 and the seal | sticker part 40 are formed opaque. Therefore, when the lid 2 is viewed from the outside, the seal portion 40 made of a different material can be visually recognized through the outer peripheral portion 22 of the main body portion 20, and the design is excellent. Further, the fact that the flap portion 30 is formed in the same color as the seal portion 40 seen through the outer peripheral portion 22 of the main body portion 20 also improves the design.

<3. Forming method of lid>
Hereinafter, a method for forming the lid 2 will be described. First, the 1st metal mold | die which has the cavity of the shape which connected the main-body part 20 and the fixing | fixed part 50 is prepared, and the raw materials of resin, such as a melted polypropylene, are poured into this and it cools and hardens | cures. Thereafter, the molded main body 20 and the fixed portion 50 are taken out from the first mold.

  Subsequently, the molded main body 20 is covered with a second mold. This mold includes a part having a cavity having the same shape as the outer shape of the flap part 30 including the plug 30a (hereinafter referred to as a first part) and a part having a cavity having the same shape as the outer shape of the seal part 40 (hereinafter referred to as the first part). 2). The first part is opened along the outer edge of the slit S4 formed in the outer peripheral part 22 of the main body part 20, and the second part is opened so as to include the outer edge of the slit S4 inside. Then, a raw material such as molten rubber or elastomer is poured into a second mold having the first part and the second part. At this time, since the upper surface side and the lower surface side of the main body portion 20 communicate with each other through the slit S4, the raw material flows from one side to the other side. Thereafter, this raw material is cooled and cured. As a result, the seal portion 40 integrated with the lower surface of the outer peripheral portion 22 of the main body portion 20 is molded, and at the same time, the seal portion 40 is integrated with the upper surface of the seal portion 40 and the inner wall of the slit S4. The protruding flap portion 30 is formed. Thereafter, the second mold is removed.

<4. How to use the container>
Then, the usage method of this container 100 is demonstrated. First, food is accommodated in the container body 1 and the lid 2 is attached. At this time, the lid body 2 is attached so that the peripheral edge portion 1a at the upper end of the container body 1 is inserted into the annular groove S3 on the lower surface of the seal portion 40 of the lid body 2. Thereby, the peripheral part 1a of the container main body 1 is tightly pinched | interposed into the reverse U-shaped inner side part 40a from both inner side and outer side in the longitudinal cross-sectional view of the seal | sticker part 40, and closely_contact | adheres to this. Moreover, if force is further applied by hand from here and the lid 2 is pushed into the container body 1 against the elastic force of the seal part 40, the seal part 40 is pressed against the peripheral part 1a of the container body 1, and both The degree of adhesion will increase. As a result, the leakage of food from the container body 1 can be reliably prevented.

  And after pushing in the cover body 2 to some extent, each fixing | fixed part 50 is bent downward. That is, the two fixing portions 50a are bent so that the grip portion 14 is inserted into the space S6, and the hook portion 53 is hooked on the protrusion 13a of the flange portion 13 of the container body 1 and fixed. Further, the remaining two fixing portions 50 are bent in the same manner. When the hand is released from the lid body 2 in this state, a force acts in a direction in which the lid body 2 and the container body 1 are separated by the elastic force of the seal portion 40. As a result, a force is exerted between the hook portion 53 and the protrusion 13a of the flange portion 13 so as to press each other up and down. Thus, each fixing portion 50 is firmly fixed to the container body 1.

  In this state, when the food is stored in a sealed state, the vent hole S5 formed on the upper surface of the main body 20 may be closed. As described above, when the flap portion 30 is bent horizontally and further pressed downward, the flap portion 30 is elastically deformed, and the plug 30a is firmly fitted in the vent hole S5. On the other hand, when heating the stored food with a microwave oven, the flap part 30 is pulled up, and the plug 30a is detached from the vent hole S5. If the container 100 is accommodated in the microwave oven and heated in this state, the steam in the container 100 is appropriately released, and the food can be heated while protecting the food from being too steamed or dried. In addition, in the state which removed the cover body 2 after heating with the microwave oven, the container main body 1 can be moved by holding the holding part 14 by hand. That is, since the container main body 1 after heating has the high temperature of the side wall part 12 and the bottom face part 11, it can reduce heat by having the holding part 14. FIG.

  In addition, after the container 100 is used, the container body 1 and the lid body 2 are cleaned. At this time, since all the parts of the container main body 1 are integrally formed of the same material, there is no fine gap and cleaning is easy. Moreover, although the main body part 20 and the fixing | fixed part 50, and the seal | sticker part 40 and the flap part 30 are formed with the different material, as above-mentioned, these parts are integrated in the important part in the lid body 2 without a gap. Has been. Accordingly, the lid body 2 is also free from fine gaps and easy to clean.

<5. Features>
In the above-described embodiment, the seal portion 40 serving as a packing is integrated with the lower surface of the main body portion 20 of the lid body 2, although it is formed of a material different from that of the main body portion 20 of the lid body 2. And there is no gap for water or dirt to enter between them.
