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, an outer frame portion 60 disposed on the outer surface of the main body portion 20, And a seal portion 40 disposed on the inner surface on the opposite side. The “inner side surface” of the main body 20 means a surface facing the internal space of the container main body 1, and the “outer surface” of the main body 20 means the opposite surface. Further, the flap portion 30 is continuous with the outer frame portion 60. 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 8, 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, an annular outer wall portion 22c that extends downward from the outer peripheral edge of the top surface portion 22b, and an annular flange 22d that protrudes outward from the lower end of the outer wall portion 22c in the horizontal direction. 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 different materials, but as will be described in detail below, the seal portion 40 is integrated with the inner 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 FIG.6 and FIG.8, the seal | sticker part 40 is reverse U shape in the longitudinal cross sectional view. Therefore, an annular groove S3 for receiving the peripheral edge 1a at the upper end of the container body 1 is formed on the lower surface, that is, the inner surface of the seal portion 40. The seal portion 40 is integrated with the inner wall portion 22a, the top surface portion 22b, and the outer wall portion 22c of the main body portion 20 without a gap.

  On the other hand, an outer frame portion 60 is disposed on the opposite side of the seal portion 40 across the outer peripheral portion 22 of the main body portion 20. The outer frame part 60 extends over the entire circumference of the outer peripheral part 22 and is an annular member that defines the contour of the main body part 20 in plan view. The outer frame portion 60 covers the entire outer wall portion 22c of the outer peripheral portion 22 from the outside. When the lid body 2 is viewed from the outer peripheral surface side, the outer wall portion 22c is not visible at all, but the flange 22d of the outer peripheral portion 22 is visible. Is exposed. As shown in FIG. 1, the outer frame portion 60 and the flange 22 d are formed to be substantially flush with each other on the side peripheral surface of the lid body 2. Furthermore, the outer frame portion 60 and the top surface portion 22b are formed so as to be substantially flush with each other also on the upper surface side of the main body portion 20. Therefore, the lid body 2 has less unevenness in appearance and is excellent in design in this respect.

  A plurality of through holes S4 are formed in the top surface portion 22b and the outer wall portion 22c of the outer peripheral portion 22 of the main body portion 20 at predetermined intervals along the circumferential direction. In FIG. 4, the positions of the through holes S <b> 4 are indicated by dotted lines for reference. However, in actual plan view, these through holes S <b> 4 are hidden under the outer frame portion 60 and cannot be seen. And the outer frame part 60 and the seal | sticker part 40 are continuing through these through-holes S4. The outer frame part 60 is integrally formed of the same material as the seal part 40.

  The flap portion 30 is continuous with the outer frame portion 60 in the vicinity of the center of the portion corresponding to one side extending in the width direction of the outer peripheral portion 22. The flap part 30 is integrally formed of the same material as the outer frame part 60. As shown in FIGS. 10 and 11, the flap portion 30 is a plate-like member having a substantially uniform thickness. However, the flap portion 30 is thin over the entire width direction of the flap portion 30 in the vicinity of the connection portion with the outer frame portion 60. Is formed. 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 frame portion 60 at the base with the thin portion as a rotation axis. In FIG. 10, the flap portion 30 in a bent state is indicated by a solid line, and the flap portion 30 in a state extending in a straight line in the vertical direction is indicated by a two-dot chain line.

  As described above, 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 is above the flat plate member 21 instead of the flat plate member 21. The horizontal surface portion 23 bulging out is present. 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 portion 30 and the upper surface of the outer frame portion 60 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 to the flange 22 d of the outer peripheral portion 22. It is connected. 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 flange 22d 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 the elastic hinge with respect to the root flange 22d with the thin portion as a rotation axis. 6 to 10, the fixed portion 50 in a bent state is indicated by a solid line, and the fixed portion 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. 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 outer frame part 60, the flap part 30, and the seal | sticker part 40 are formed opaque. The main body portion 20 is disposed only inside the outer frame portion 60 in plan view. In other words, the main body portion 20 of the transparent or translucent lid is surrounded by the opaque outer frame portion 60 at the outermost edge. It is. Therefore, the lid 2 here gives a viewer a clear impression of outline and is excellent in 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 portion having a cavity with a shape connecting the outer frame portion 60 and the flap portion 30 (hereinafter referred to as a first portion) and a portion having a cavity with the same shape as the outer shape of the seal portion 40 (hereinafter referred to as a second portion). A region). 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 20 are communicated with each other through the through hole 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 inner surface of the outer peripheral portion 22 of the main body portion 20 is molded, and at the same time, the outer frame portion 60 integrated with the outer surface of the seal portion 40 and the outer frame portion 60 are continuous with this. The flap portion 30 is formed. At this time, the inside of the through hole S4 is also solid with the same material as the outer frame portion 60 and the seal portion 40. 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 seal part 40 from both inner and outer sides in a longitudinal sectional view, and comes into close contact therewith. 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 outer frame part 60, the seal | sticker part 40, and the flap part 30 are formed with the different material, as above-mentioned, these parts are the key parts. It is integrated without gaps. Accordingly, the lid body 2 is also free from fine gaps and easy to clean.

<5. Features>
In the said embodiment, although the seal part 40 which plays the role of packing is formed from the material different from the main-body part 20 of the cover body 2, the inner surface (the container main body of the container main body 20) of the cover body 2 is formed. Integrated on the inside surface). Therefore, there is no gap for water and dirt to enter between the main body 20 and the seal portion 40, and there is no increase in the number of parts due to the presence of the seal portion 40. On the other hand, an outer frame portion made of a different material from the main body portion 20 of the lid body 2 is also integrated with the outer surface of the main body portion 20 of the lid body 2 (the opposite surface to the inner side surface facing the inside of the container main body). Also, there is no gap for water or dirt to enter between them, and there is no increase in the number of parts due to the presence of the outer frame portion 60. Furthermore, although the outer frame portion 60 and the seal portion 40 are formed of a relatively soft material, they are integrated with the relatively hard main body portion 20, and therefore there is little risk of deformation even after repeated use. Furthermore, since the outer frame portion 60 and the flap portion 30 are integrally formed of the same material, there is no increase in the number of parts due to the presence of the flap portion 30. That is, here, the main body portion 20, the outer frame portion 60, the seal portion 40, and the flap portion 30 are made of one component, so that the number of components is small, which is advantageous for cleaning. In summary, here, the risk of deformation of the outer frame is reduced, and there is little risk of parts being lost, and cleaning is easy.

  Moreover, in the said embodiment, the outer frame part 60 and the flap part 30 following this, and the seal | sticker part 40 are the other side from the one side of the main-body part 20 through the through-hole S4 formed in the main-body part 20. It is integrally formed by pouring the same material on the side. Therefore, the molding process of the flap part 30, the outer frame part 60, and the seal part 40 is simplified.
