Description

  The present invention relates to a container with an opening / closing lid formed by detachably attaching an opening / closing lid to an opening of a container having an opening upward. In particular, it can be applied to containers made of glass, resin, or ceramic.

  Conventionally, containers with open / close lids made of synthetic resin have been widely used for hermetically storing foods such as prepared dishes cooked at home. When this closed type container with an open / close lid is stored in a refrigerator with side dishes etc. stored in it, the smell, moisture, juice, etc. of the side dishes leaks out and adheres to other foods, This is useful in that it can be prevented from moving.

  The container with an opening / closing lid has a container body, an opening / closing lid for closing the opening of the container body, and a locking member for closely holding the opening / closing lid on the opening of the container body. And in order to prevent the smell and moisture leak from the inside of a container main body, and in order to raise the sealing degree of the opening-and-closing lid with respect to the opening part of a container main body, various devices are made | formed by the said locking member. For example, in a rectangular (lunch box-shaped) container with an opening / closing lid, locking members are provided on the two opposite sides of the opening / closing lid so that the opening / closing lid is in close contact with the container body. By locking (locking) with the flange, there is a method in which the opening / closing lid is brought into close contact with the opening of the container body and the inside of the container body is sealed (see, for example, Patent Document 1). However, in the case where the locking members are formed on the two opposite sides, the sealing degree is not sufficient yet, and a locking member is provided on all four sides of the open / close lid to seal the inside of the container body. (For example, refer to Patent Document 2).

Japanese Patent Laid-Open No. 06-156519 JP 2004-307059 A

  However, in the conventional container with an opening / closing lid, since a locking member is attached to the four sides of the opening / closing lid in order to obtain a good hermetically sealed state, four locking members are provided each time the lid is opened and closed. Must be locked or unlocked at the locking edge of the container body. This unlocking operation is very troublesome for the user, and there is a concern about the situation in which all four locking members are used without being locked. Moreover, in the conventional container with an opening / closing lid, the locking edge and the locking mechanism are exposed to the outside so that the locking edge and the locking mechanism can be clearly understood, and the aesthetic appearance of the entire container is impaired.

  The present invention has been made by paying attention to such conventional problems, and the object of the present invention is to obtain a good degree of sealing even if the number of engagement points between the opening / closing lid and the container body is reduced, and An object of the present invention is to provide a container with an open / close lid excellent in design.

  In order to achieve the above-described object, a container with an opening / closing lid according to the present invention covers a container main body that opens upward and a locking edge projects from the outer periphery of the opening, and covers the opening of the container main body. An opening / closing lid having a top and a flange hanging from the periphery of the top so as to surround the periphery of the side wall of the container body including the locking edge, and attached to the lower surface of the top of the top of the flange A ring-shaped seal packing, a notch in a part of the flange, a locking member formed in the notch, and a lock provided on the locking member and lockable to the locking edge of the container body And a stop projection.

In addition, the container with an opening / closing lid according to the present invention opens upward, and a container body having a locking edge projecting on the outer periphery of the opening,
An opening / closing lid having a top part covering the opening part of the container body, and a flange hanging from the periphery of the top part so as to surround the periphery of the side wall of the container body including the locking edge;
A ring-shaped seal packing attached to a position corresponding to the opening end of the container body on the lower surface of the top portion inward from the flange;
A locking member that has a notch in at least one location of the flange, and is continuously provided so as to be rotatable so as to open outward of the flange formed in the notch;
A first locking projection provided inside the locking member and lockable to the locking edge of the container body;
A second locking projection that protrudes from an inner position of another flange facing the flange provided with the locking member and can be locked to a locking edge of the container body. To do.

Furthermore, the container with an opening / closing lid according to the present invention is:
A container body that opens upward and has a locking edge protruding from the outer periphery of the opening;
An opening / closing lid having a top part covering the opening part of the container body, and a flange hanging from the periphery of the top part so as to surround the periphery of the side wall of the container body including the locking edge;
A ring-shaped seal packing mounted at a position corresponding to the open end of the container body on the lower surface of the top portion inward from the flange;
A locking member that has a notch in at least one of the flanges facing or adjacent to each other among the flanges and is continuously connected so as to be able to rotate so as to open outward of the flange formed in the notch.
And a locking projection that protrudes from the locking member and can be locked to the locking edge of the container body.

  According to the present invention, since the flange is formed on the opening / closing lid so as to surround the periphery of the side wall of the container body including the locking edge, and the locking member is formed on the notch of the flange, the opening / closing lid is displaced at the time of locking. The opening / closing lid can be securely crimped to the container body. Moreover, since the periphery of the side wall of the container body is surrounded by the flange and the locking member so that at least the locking edge is covered, the opening / closing lid is not easily displaced even after the opening / closing lid is crimped, and the sealing is easily maintained. Further, since the flange and the locking member are formed so that the locking edge is covered around the side wall of the container body, the appearance of the entire container with the opening / closing lid is simplified, and the design is improved.

The present invention has been briefly described above. Further, modes for carrying out the invention described below will be described in detail with reference to the accompanying drawings.
First, a container with an opening / closing lid according to an embodiment of the present invention opens upward, a container body having a locking edge projecting on the outer periphery of the opening, and a top part covering the opening of the container body, An opening / closing lid having a flange hanging from the periphery of the top so as to surround the periphery of the side wall of the container main body including the locking edge, and a ring-shaped attached to the lower surface of the top inward from the flange A seal packing, a notch in a part of the flange, a locking member formed in the notch, a locking protrusion provided on the locking member and lockable to the locking edge of the container body; , With.
Example 1
In this embodiment, the container body and the opening / closing lid are rectangular having four sides, and two different types of locking members are arranged opposite to the opening / closing lid.

  Hereinafter, an embodiment of the container with an opening / closing lid will be specifically described with reference to FIGS. The container with an opening / closing lid of the present embodiment includes an opening / closing lid 11 and a container body 12 made of heat-resistant glass. Among these, the opening / closing lid 11 is a molded product made of synthetic resin, and is hard but has elasticity that is slightly deformable as a whole. Specifically, it is a polypropylene resin or a silicone resin.

 The open / close lid 11 integrally includes a top portion 13 that is substantially square or rectangular in plan view and a flange 14 that hangs downward from the four peripheral edges of the top portion 13. As shown in FIGS. 7 and 8, the top portion 13 includes an annular flat portion 13 a that is flat over a predetermined width of the peripheral portion, and an inclined portion that is inclined from the annular flat portion 13 a toward the center portion of the top portion 13. 13b and the inclined flat portion 13b are integrally provided with a rectangular flat portion 13c lower than the annular flat portion 13a.

 The flange 14 has a shape slightly curved downward and slightly outward from the periphery of the top portion 13, and a predetermined length portion near the connection portion with the top portion 13 is a thick portion 14a. The lower part of the lower part is a thin part 14b having substantially the same thickness as the top part 13, and the lower part is a thick change part 14c that gradually becomes thicker downward. The hanging length (width in the vertical direction) of the flange 14 reaches approximately 1/3 to 1/2 of the vertical width of the container body 12 and sufficiently covers a locking edge 25 of the container body 12 described later from the outside. Has a length of size.

 Further, a rectangular ring-shaped hanging piece 15 projects from the lower surface of the top portion 13, specifically, at a portion where the annular flat plate portion 13 a of the top portion 13 continues to the inclined portion 13 b. The outer periphery of the lower end portion of the hanging piece 15 is a tapered portion 15a that gradually becomes thinner downward. A rectangular ring groove 16 is formed between the hanging piece 15, the thick portion 14a of the flange 14, and the flat plate portion 13a. The ring groove 16 is opened downward, and a seal packing 24 described later is mounted inside.

 As shown in FIG. 3 and FIG. 7, a notch 17 that penetrates into and out of the flange 14 and opens downward is formed at the center of the left side surface of the flange 14. The opening width of the notch 17 is as wide as about ½ of the width of the opening / closing lid 11 (approximately the same length as the straight portion of the side wall of the main body container 12). The notch 17 can accommodate the first locking member 19 via an extremely thin thin portion 18 continuous with the upper surface of the annular flat plate portion 13a. This thin portion 18 is as shown in FIG. The width W2 of the first locking member 19 is as wide as about ½ of the width dimension W1 of the opening / closing lid 11. That is, the widths of the notch 17 and the first locking member 19 are substantially the same.

 Therefore, the first locking member 19 can be rotated around the thin portion 18, that is, with the thin portion 18 as a hinge portion, and can be accommodated and removed in the notch 17. 1 and 4 show a state in which the first locking member 19 is accommodated in the notch 17, and FIGS. 2, 3, 5, 6, and 7 show that the locking is released. The state which the 1st latching member 19 was flipped up to the side of the container main body 12 is shown.

  A first locking projection 20 projects from the inner side surface of the first locking member 19. The first locking protrusion 20 extends horizontally in the width direction in the middle of the first locking member 19 as much as the length W2 of the first locking member 19. Thus, by having made the length of the width direction of the 1st latching protrusion 20, it becomes the same length as the linear part of the side wall of the container main body 12, and it can lock the whole one side. As shown in FIG. 9, the first locking projection 20 has a locking claw portion 20a protruding from the upper edge of the distal end portion in the extending direction. The locking claw portion 20a can be locked to a locking edge 25 described later provided outside the container body 12. Here, the outer side surface of the first locking member 19 is formed so as to be flush with the outer side surface of the flange 14 when the locking claw portion 20a is locked to the locking edge 25. The (pick piece 19a) is formed to be longer than the lower end of the flange 14. Thereby, the user can distinguish the 1st locking member 19 easily. Moreover, since the distance with the latching edge 25 can be lengthened, the removal after latching can be performed easily. It is also possible to discriminate by curving only the lower end. In the above and FIG. 1, the lower end of the first locking member 19 is made longer than the lower end of the flange 14, but the lower end of the first locking member 19 and the lower end of the flange 14 are connected. The same length is a preferable shape from the viewpoint of design. As described above, the first locking protrusion 20 is formed in the middle of the hanging length of the first locking member 19, so that the first locking protrusion 20 is extended to the lower end of the first locking member 19. The distance becomes longer, and locking and unlocking can be performed very easily. That is, the relationship between “the length from the thin portion 18 to the first locking projection 20” and “the length from the first locking projection 20 to the lower end of the first locking member” is expressed as “the thin portion It is preferable to satisfy “the length from 18 to the first locking projection 20” ≦ “the length from the first locking projection 20 to the lower end of the first locking member 19”.

 On the other hand, as shown in FIG. 4, a notch 21 is formed in the center of the right side surface of the flange 14 so as to open sideways and downward. This notch 21 is formed so as to leave a thin portion 21 a in a part of the flange 14. The opening width W3 of the notch 21 is as wide as about ½ of the width dimension W1 of the opening / closing lid 11 (substantially the same length as the straight portion of the side wall of the main body container 12). A rectangular protrusion insertion hole 21b is provided at the center of the thin portion 21a.

 In the notch 21, a second locking member 22 with which the notch 21 is fitted is fitted as shown in FIG. The thickness and shape of the second locking member 22 is such that, when the second locking member 22 is fitted into the notch 21, the thickness of the portion including the second locking member 22 is that of the flange 14 where the notch 21 is not provided. It is equivalent to the thickness. And the 2nd latching protrusion 23 is protrudingly provided by the inner surface of this 2nd latching member 22 integrally. The second locking protrusion 23 protrudes from the inner surface of the flange 14 toward the center of the flange 14 through the protrusion insertion hole 21b.

 Further, a locking claw similar to that provided on the first locking projection 20 may be provided at the tip of the second locking projection 23. The reason why the second locking member 22 having the locking protrusion 23 is fitted into the notch 21 is that the locking protrusion protruding on the inner surface of the flange 14 of the opening / closing lid 11 is formed integrally. This is because it is difficult in the molding process.

 A seal packing 24 is fitted in the ring groove 16. The seal packing 24 can be attached to and detached from the ring groove 16 to facilitate cleaning of the ring groove 16 together with the seal packing 24. The seal packing 24 is made of an elastic member such as rubber or synthetic resin (particularly silicone resin), and here, a ring-shaped rubber tube is used. The seal packing 24 is locked to the ring groove 16 in a compressed state, and does not easily fall off the ring groove 16. Part (lower part) of the seal packing 24 protrudes out of the opening of the ring groove 16. The seal packing 24 is particularly preferably made of a hollow silicone resin having a rectangular cross section. In addition, in FIG. 10, the rod-shaped thing was shown in order to demonstrate clearly that the shape of the seal packing 24 is a cross-sectional rectangle. When it is actually inserted into the ring groove 16, it is used as an annular shape in which both ends of a rod-shaped member are bonded.

  On the other hand, the container body 12 can be made of glass, resin, or ceramic. For example, if it is made of heat-resistant glass, it can be used for heat treatment of food in a microwave oven or oven. The container body 12 has a substantially rectangular shape in plan view. The container body 12 has a locking edge 25 projecting from the outer surface (outer peripheral surface) near the opening edge. The bottom surface of the locking edge 25 is engageable with a locking claw 20a of the first locking projection 20 and a tip end portion of the second locking projection 23 or a locking claw portion (not shown). It has a notch shape.

 The opening / closing lid 11 having such a configuration is attached to the container body 12 as follows. First, the first locking member 19 of the opening / closing lid 11 is rotated around the thin portion 18 so as to be substantially horizontal as shown in FIGS. 2, 3, 5 to 7 and 9. Start it up. Subsequently, the opening / closing lid 11 as shown in FIG. 7 is opposed to the container body 12 as shown in FIG. 11, and the opening / closing lid 11 is further lowered in a direction covering the opening of the container body 12. At the beginning of the lowering operation of the opening / closing lid 11, the opening / closing lid 11 is held downward and the opening / closing lid 11 is operated so that the second locking protrusion 23 enters the lower surface of the locking edge 25 of the container body 12. To do. And the opening / closing lid | cover 11 is returned to a horizontal state, maintaining the engagement state of the 2nd latching protrusion 23 and the latching edge 25. FIG.

 In this state, the second locking projection 23 and the locking edge 25 are locked, and a part of the opening edge of the container body 12 is brought into contact with the seal packing 24 in the ring groove 16. Subsequently, the top surface of the top portion 13 is pushed down with a fingertip or the like. Then, the seal packing 24 in the ring groove 16 contacts the entire circumference of the opening edge of the container body 12. Therefore, the first locking member 19 is rotated downward about the thin portion 18, and the first locking member 19 is accommodated in the notch 17 formed on the side of the flange 14.

 This turning operation is performed with a slightly stronger force toward the outer surface of the container body 12. Therefore, the first locking projection 20 of the first locking member 19 enters the container body 12 corresponding to the first locking projection 20 so as to slide into the lower surface of the locking edge 25 at a predetermined portion. In this operation, the first locking projection 20 supports the locking edge 25 so as to lift upward, and the first locking projection 20 and the locking edge 25 are locked.

 Therefore, in such a locked state, the opening edge of the container body 12 is more strongly abutted against the seal packing 24 in the ring groove 16, and the opening edge of the container body 12 is also on the second locking projection 23 side. It is strongly abutted against the seal packing 24 in the groove 16. For this reason, the seal packing 24 is pushed and deformed by being pushed by the opening edge of the container body 12, and the opening / closing lid 11 is crimped to the opening of the container body 12 via the seal packing 24 as shown in FIG. . Thereby, the scent of the side dish, soup, etc. in the container main body 12 will not leak outside.

 On the other hand, in order to remove the opening / closing lid 11 from the container main body 12, the knob 19 a of the first locking member 19 is lifted with a fingertip, and is rotated so as to jump up around the thin portion 18. As a result, the first locking projection 20 of the first locking member 19 is removed from the lower surface of the locking edge 25 of the container body 12, and the repulsive force of the seal packing 24 is also applied. It floats slightly above the opening edge of the container body 12.

  As a result, the opening / closing lid 11 is tilted to the left with the second locking projection 23 and the locking portion of the locking edge 25 of the container body 12 as the center, and the engagement state of the locking portion is also loosened. Therefore, by pulling the opening / closing lid 11 away from the container main body 12 while rotating the opening / closing lid 11 in the direction to release the locked state, the locked state is canceled and the opening of the container main body 12 is opened. Accordingly, stored items such as side dishes in the container body 12 can be taken out. That is, the opening / closing lid 11 can open the opening of the container body 12 by a simple operation of lifting the first locking member 19 with a finger.

(Example 2)
In this embodiment, the container main body and the opening / closing lid are rectangular with four sides, and the same shape of the locking member is disposed opposite to the opening / closing lid.
In the first embodiment, the case where the first locking member 19 with the first locking protrusion 20 is attached to only one side (surface) of the opening / closing lid 11 is shown. In the second embodiment, as shown in FIGS. 12 to 14, the same engagement as that of the first locking member 19 shown in the first embodiment is provided at each of the two opposite sides (surfaces) of the opening / closing lid 11 </ b> A. The stop member 19A is attached.

 In this case, the notch 21, the thin portion 21a, the protrusion insertion hole 21b, and the second locking member 22 with the second locking protrusion 23 on the side surface of the flange 14 shown in FIG. 7 are omitted. In this opening / closing lid 11A, when mounting this on the container main body 12, each locking member 19A is flipped upward, the opening / closing lid 11A is placed in a substantially horizontal state, and is covered over the opening of the container main body 12. Lightly push down the top 13 with your finger. Then, when the seal packing 24 comes into contact with the opening edge of the container body 12, the two opposing locking members 19A are turned downward separately or simultaneously.

 As a result, the first locking protrusions (hereinafter simply referred to as locking protrusions) 20 of the locking members 19A slide into the lower surface of the locking edge 25 of the container body 12 and are locked thereto. For this reason, the opening / closing lid 11 </ b> A descends according to the operation amount of the locking member 19 </ b> A with respect to the container body 12, and the opening edge of the container body 12 is abutted against the seal packing 24 in the ring groove 16 with a strong pressure. For this reason, the space between the opening / closing lid 11 </ b> A and the opening of the container body 12 can be sealed in a watertight and airtight manner.

 Also in this embodiment, each locking member 19 </ b> A has a width that is about half the width of one side of the opening / closing lid 11 </ b> A, and the flange 14 substantially surrounds the side wall of the container body 12 including the locking edge 25. In a form that hangs downward in an L shape, it is thicker than other parts including the top plate. Thus, when the locking protrusion 20 of the locking member 19A is forcibly locked to the locking edge 25 of the container body 12, the locking member 19A is not easily bent and is attached to the opening / closing lid 11A. The opening edge of the container body 12 can be pressed against the seal packing 24 with a strong force.

For this reason, by the operation of the locking member 19A, a sufficient pressure-bonded state between the opening / closing lid 11A and the container main body 12 other than the portion corresponding to the locking member 19A is also obtained. And odors can be prevented from leaking into the refrigerator. Further, since the locking edge 25 of the container body 12 corresponding to the locking protrusion 20 is covered from the outside by the locking member 19A and the flange 14, these are not seen from the outside of the opening / closing lid 11 or the container body 12, Good appearance can be maintained.
There are no other protrusions on the outer periphery of the container main body 12 other than the locking edge 25, and the handling and cleaning of the container main body together with the opening / closing lid 11 can be simplified, and the cost can be kept low. In addition, since the shape from the opening end of the container body to the locking edge 25 is a curved slope, even if the container body itself with the opening / closing lid 11 removed is arranged on the table, it can be used without a sense of incompatibility.
In the above embodiment, two locking members are formed at the opposing position of the opening / closing lid. However, as long as the container is a rectangular container, the locking members may be formed on all four sides, or the flanges at the opposing position. You may form two or more locking members in each. If the container has a circular horizontal cross section, the locking member can be formed at an even number (2 or 4 locations) and an odd number (3 or 5 locations). 12 to 14, the lower end of the first locking member 19 is made longer than the lower end of the flange 14, but the lower end of the first locking member 19 and the lower end of the flange 14 Those having the same length are preferable shapes from the viewpoint of design. Note that the lower end of the locking member 19A may be shorter than the lower end of the flange 14 as long as the distance from the first locking protrusion 20 to the lower end of the locking member 19A can be secured by 10 mm or more.

(Example 3)
As shown in the conceptual diagram of FIG. 15, the container with an opening / closing lid of the third embodiment is such that the container body 12 and the opening / closing lid 11 </ b> B form a rectangle in plan view. Among these, the opening / closing lid 11B has flanges 14 on four sides, and has a notch 17 at the center of two flanges 14 adjacent to each other. These notches 17 penetrate the inside and outside of the flange 14 and open downward. The upper edges of these notches 17 extend to the peripheral edge of the top portion 13 of the opening / closing lid 11B. Each notch 17 can receive one locking member 19B through a thin portion 18 similar to that shown in FIG.

  Here, the width of the locking member 19 </ b> B is as wide as about ½ of the width dimension of the opening / closing lid 11, and is substantially the same width as the notch 17. Therefore, the locking member 19B can be rotated around the thin portion 18, that is, the thin portion 18 as a hinge portion, and can be accommodated and removed in the notch 17. FIG. 15 shows a state in which the locking member 19B is housed in the notch 17, and FIG. 16 shows a state in which the locking is released and the locking member 19B is flipped up to the side of the container 12.

  In the fitted state shown in FIG. 15, the outer surface of the locking member 19 </ b> B is flush with the outer surface of the flange 14. Similarly to the above, the locking projection 20 provided on the locking member 19B is provided with a locking claw portion 20a similar to that shown in FIG. 20 a can be locked to the locking edge 25 of the container body 12. Further, although omitted in FIGS. 15 and 16, a seal packing 24 is fitted in the ring groove 16 on the lower surface of the opening / closing lid 11B as shown in FIG. 8 in the same manner as described above.

  The locking protrusion 20 extends horizontally in the width direction in the middle of the locking member 19B by the same length as the locking member 19B. By using such a locking protrusion 20, the entire length of the locking claw 20 a can be reliably locked to the locking edge 25 of the container body 12. As a result, it is possible to increase the degree of adhesion and sealing of the open / close lid 11B with respect to the container body 12.

  On the other hand, the container main body 12 is made of heat-resistant glass, which can be used for heat treatment of food in a microwave oven or oven. The container body 12 has the above-described locking edge 25 protruding on the outer surface (outer peripheral surface) near the opening edge. The lower surface of the locking edge 25 has a shape that allows the locking claw portion 20a of the locking projection 20 to be locked.

  The opening / closing lid 11B having such a configuration is attached to the container body 12 as follows. First, the locking member 19B of the opening / closing lid 11B is rotated around the thin portion 18 and is raised obliquely upward as shown in FIG. Subsequently, the opening / closing lid 11 </ b> B is opposed to the container body 12 as shown in FIG. 11, and the opening / closing lid 11 </ b> B is lowered in a direction to cover the opening of the container body 12. At the beginning of the lowering operation of the opening / closing lid 11 </ b> B, the opening / closing lid 11 </ b> B is placed so that the lower surface of the top plate 13 of the opening / closing lid 11 </ b> B slightly touches the opening edge of the container body 12. Thereby, the upper surface of the opening edge of the container body 12 is lightly pressed against the seal packing 24 in the ring groove 16. Subsequently, the locking member 19 </ b> B is rotated around the thin portion 18 and fitted into the notch 17.

  This fitting (fitting) operation is performed with a slightly stronger force toward the outer surface of the container body 12. For this reason, the latching protrusion 20 in this latching member 19B enters so that it may slide into the lower surface of the latching edge 25 in the predetermined part of the container main body 12 which opposes this. In this operation, the locking projection 20 supports the locking edge 25 so as to lift upward, and the locking projection 20 and the locking edge 25 are in a sufficiently fitted state. In this state, the other flanges 14 not provided with the locking member 19B are pressed against and held by the locking edge 25 so that the inner side faces the outer surface of the opposing locking edge 25.

  Therefore, in the fitted state, the upper surface of the opening edge of the container body 12 is strongly abutted against the seal packing 24 in the ring groove 16. For this reason, the seal packing 24 is pushed and deformed by being pressed by the upper surface of the opening edge of the container main body 12, and the opening / closing lid 11 </ b> B seals the opening of the container main body 12 through the seal packing 24. Thereby, it can seal so that the side dish in the container main body 12, the smell of soup, etc. may not leak outside.

  On the other hand, in order to remove the opening / closing lid 11 from the container main body 12, the lower end portion of the locking member 19 </ b> B is lifted with a fingertip, and is rotated so as to be flipped upward around the thin portion 18. As a result, the locking projection 20 on the locking member 19B is detached from the lower surface of the locking edge 25 of the container body 12, and the repulsive force of the seal packing 24 is also applied. In this part, the opening / closing lid 11B is above the opening edge of the container body 12. Float up.

  Therefore, the opening of the container body 12 is opened by pulling the opening / closing lid 11B away from the container body 12. Thereby, stored items such as side dishes can be taken out from the container body 12. That is, the opening / closing lid 11B can easily open the opening of the container body 12 by lifting the locking member 19B with a finger. In this embodiment, a locking projection (not shown) similar to the second locking projection 23 shown in FIG. 7 is provided on the inner surface of the flange on the side where the locking member 19B is not provided. The opening of the container body 12 can be more reliably sealed by the opening / closing lid 11B.

Example 4
As shown in the conceptual diagram of FIG. 17, the container body 12 and the opening / closing lid 11C of the container with the opening / closing lid of Example 4 are substantially rectangular in a plan view. Among these, the opening / closing lid 11C has flanges 14 integrally on the four sides, and each of the four side flanges 14 has a notch (cut groove) 17A at the center. These notches 17A extend vertically from the lower edge of the flange 14 to the peripheral edge of the top 13 of the flange. A fold line (folding line) 31 is formed on a straight line connecting positions where the notches 17 </ b> A of two adjacent flanges 14 of the flanges 14 reach the peripheral edge of the top portion 13. As a result, the triangular open / close region 32 of the top portion 13 can be folded back (rotated) about the fold line 31 as shown in FIG.

  Each triangular open / close region 32 and the flange 14 continuous therewith constitute a locking member 19C, and in the figure, the remaining top 13 sandwiched between the two open / close regions 32 is rotated around the fold line 31. Is possible. By this rotation, the opening / closing region 32 opens and closes the opening in the vicinity of the two opposite corners of the container body 12. On the inner side surface of the flange 14 in the locking member 19C, a locking projection 20 having a locking claw portion 20a similar to that described above is provided over the entire length of the inner side surface. These locking projections 20 are fitted to the locking edge 25 on the outer side of the container body 12 by pushing down the top portion 13 on the side of the opening / closing region 32 in the state shown in FIG. 18 and turning the fold line 31 as a hinge portion. It becomes possible.

  On the other hand, as shown in FIG. 18, the opening at the corner of the container body 12 can be opened by flipping the top 13 on the open / close region 32 side around the crease. Here, since the locking member 19C is formed so that the material of the opening / closing lid 11C has a predetermined bending characteristic and expansion / contraction characteristic by the synthetic resin as described above, the engagement / fitting to the locking edge 25 is performed. The release operation can be performed smoothly.

  On the other hand, the container body 12 is made of, for example, heat-resistant glass, which can be used for heat treatment of food in a microwave oven or oven. The container body 12 is provided with a locking edge 25 as described above on the outer surface (outer peripheral surface) near the opening edge. The lower surface of the locking edge 25 has a shape that allows the locking claw portion 20a of the locking projection 20 to be locked.

  The opening / closing lid 11C having such a configuration is attached to the container body 12 as follows. First, the locking member 19C of the opening / closing lid 11C that is separated from the container main body 12 is rotated about the fold line 31 and lifted with the corners obliquely upward as shown in FIG. Subsequently, the opening / closing lid 11 </ b> C is opposed to the container main body 12, and is lowered so as to cover the opening of the container main body 12 while keeping it horizontal. Thus, the opening / closing lid 11C is placed on the opening so as to close it. Subsequently, the finger is placed on the area 32 of the top portion 13 and the locking member 19C is rotated with the crease 31 as the center. As a result, the locking projection 20 is fitted into the lower surface of the locking edge 25 of the container body 12 opposite to the locking projection 20 in the same manner as described above, and the state shown in FIG. 17 is obtained.

  Therefore, in such a fitting state, the opening edge of the container body 12 is strongly abutted against the seal packing 24 in the ring groove 16. Therefore, the seal packing 24 is pushed by the opening edge of the container main body 12 to bend and deform, and the opening / closing lid 11C seals the opening of the container main body 12 via the seal packing 24. Thereby, it can seal so that the water | moisture content, smell, etc. of the side dish and soup in the container main body 12 may not leak outside.

  Here, the seal packing 24 is provided in the ring groove 16 on the lower surface of the top portion 13 including the entire opening / closing lid 11C, that is, the opening / closing region 32 and the portion excluding the opening / closing region 32, as described above, and the locking member. When 19C opens and closes, it expands and contracts. Therefore, when the locking member 19C is closed as shown in FIG. 17, the seal packing 24 is compressed, and the juice and smell in the container body 12 do not leak outside. Further, the seal packing 24 does not hinder the opening operation of the locking member 19C.

  In order to remove the opening / closing lid 11 from the container main body 12, the lower edge of the locking member 19 </ b> C is lifted with a fingertip, and is rotated so as to be flipped up about the fold line 31. As a result, the locking projection 20 on the locking member 19C is detached from the lower surface of the locking edge 25 of the container main body 12, and the repulsive force of the seal packing 24 is also applied. At this part, the opening / closing region 32 of the locking member 1C becomes the container main body. Float above the 12 opening edges.

  Therefore, the opening / closing region 32 of the locking member 1 </ b> C is separated from the container body 12, and the top portion 13 adjacent to the opening / closing region 32 is simultaneously lifted from the container body 12. Thereby, the opening part of the container main body 12 whole is opened. Thereby, stored items such as side dishes in the container body 12 can be taken out. That is, the opening / closing lid 11C can easily open the opening of the container body 12 by an operation of lifting the locking member 19C with a finger.

(Example 5)
In the container with an opening / closing lid of the fifth embodiment, as shown in the conceptual diagram of FIG. 19, the container body 12 and the opening / closing lid 11D form a substantially rectangular shape in plan view. Among these, the opening / closing lid 11D has flanges 14 on the four sides, and the flanges 14 on the long sides opposed to these flanges 14 are positions obtained by dividing the length (the length in the horizontal direction) into three equal parts at a predetermined ratio. Two notches (cut grooves) 17B are formed in each. These notches 17B extend vertically from the lower edge of the flange 14 to the peripheral edge of the top portion 13 of the flange 14.

  In the two long-side flanges 14 facing each other, a fold line (folding line) 34 is formed on a line connecting positions where the notch 17B reaches the peripheral edge of the top portion 13. The fold line 34 enables the rectangular opening / closing area 33 to be folded upward on the top portion 13. These open / close regions 33 and the flanges 14 that are continuous with these and have a U-shape in plan view constitute a locking member 19 </ b> D, and fold lines 34 with respect to the top 13 of the remaining region between the open / close regions 33 and 33. It can be turned around. By this rotation, two regions (one open / close region) 33 at both ends in the length direction of the opening of the container body 12 are opened and closed.

  Further, the inner surface corresponding to the short side of the container main body of the flange (which is U-shaped in plan view) 14 in these locking members 19D is the same as that described above over the entire length of these inner surfaces. A locking projection 20 having a locking claw 20a is horizontally arranged. These locking projections 20 can be fitted to the locking edge 25 on the outer side of the container body 12 by rotating around the fold line 34 so as to push down the top portion 13 on the opening / closing region 33 side. Yes. On the other hand, when the top portion 13 on the open / close region 33 side is flipped up around the fold line 34, the vicinity of both ends of the opening of the container body 12 is opened. Here, the locking member 19D is formed so that the material of the opening / closing lid 11D has a predetermined bending characteristic and expansion / contraction characteristic by the synthetic resin as described above. The release operation can be easily performed.

  The container main body 12 is made of heat-resistant glass as described above, and can be used for heat treatment of food in a microwave oven or oven. The container body 12 is provided with a locking edge 25 as described above on the outer surface (outer peripheral surface) near the opening edge. The lower surface of the locking edge 25 has a shape that allows the locking claw portion 20a of the locking projection 20 to be locked.

  The opening / closing lid 11D having such a configuration is attached to the container body 12 as shown below. First, the open / close region 33 of the open / close lid 11D separated from the container body 12 is rotated about the fold line 34 and lifted obliquely upward as shown in FIG. Subsequently, the opening / closing lid 11D is opposed to the container main body 12 and is lowered so as to cover the opening of the container main body 12 while keeping it horizontal. Thus, the opening / closing lid 11D is placed on the opening so as to cover it. Subsequently, the opening / closing region 33 of the locking member 19 </ b> D is rotated so as to be pushed down centering on the fold line 34. Thereby, the latching protrusion 20 is fitted so as to slide on the lower surface of the latching edge 25 of the container body 12 facing the latching projection 20, and the state shown in FIG. 19 is obtained.

  Therefore, in such a fitting state, the seal packing 24 in the ring-shaped ring groove 16 on the lower surface of the opening / closing lid 11D is strongly abutted against the opening edge of the container body 12. For this reason, the seal packing 24 is pushed and bent by the opening edge of the container body 12, and the opening / closing lid 11 </ b> D seals the entire opening of the container body 12 through the seal packing 24. Thereby, it can seal so that the side dish in the container main body 12, the smell of soup, etc. may not leak outside.

  On the other hand, in order to remove the opening / closing lid 11 from the container main body 12, the lower edge of the flange 14 on the side of the locking member 19D is lifted with a fingertip, and is rotated so as to spring up around the crease 34. As a result, the locking projection 20 of the locking member 19D is detached from the lower surface of the locking edge 25 of the container body 12, and the repulsive force of the seal packing 24 is also applied. At this part, the opening / closing lid 11D is more than the opening edge of the container body 12. Float slightly above.

  Subsequently, by pulling the entire opening / closing lid 11 </ b> D away from the container main body 12, the mutual engagement state is canceled, and the entire opening of the container main body 12 is opened. Thereby, stored items such as side dishes in the container body 12 can be taken out. In other words, the opening / closing lid 11D can easily open the opening of the container body 12 by lifting the locking member 19D with a finger.

(Embodiment 6) As shown in the conceptual diagram of FIG. 21, the container with an opening / closing lid of the embodiment 6 is such that the container body 12 and the opening / closing lid 11E form a substantially rectangular shape in plan view. Among these, the opening / closing lid 11E is made of a synthetic resin and is made of a plate having a relatively large thickness. This open / close lid 11E has a top portion 13A and flanges 14 that are continuous on the four sides of the top portion 13A, and each of the top portion 13A and the flange 14 following the top portion 13A has a predetermined depth as shown in FIG. Guide notches 35a and 35b which are notches (smaller than the thickness of the plate material) are formed.

  A locking member 36 bent in a U-shape as shown in FIG. 22 can be attached to the guide cutouts 35a and 35b. The locking member 36 is formed in a U shape by a synthetic resin thinner than the thickness of the plate material of the opening / closing lid 11E, and has a thickness having predetermined elasticity and deflection characteristics as a whole. The locking member 36 includes a horizontal piece 36a and a locking piece 36b extending so as to hang from both ends of the horizontal piece 36a. A locking projection 20 having a locking claw portion 20a similar to that shown in FIG. 9 protrudes from the inner surface of each locking piece 36b. Further, the portion where the locking piece 36b continues to both ends of the horizontal piece 36a is a thin portion 18 similar to that shown in FIG. For this reason, each locking piece 36b can be rotated with the thin portion 18 as a hinge, and can be flipped outward as indicated by a chain line. A seal packing 24 is inserted into a ring groove 16 similar to that shown in FIGS. 7 and 8 formed on the lower surface of the opening / closing lid 11E.

  The opening / closing lid 11E having such a configuration has a size capable of closing the opening of the container main body 12, and is placed so as to cover the opening as shown in FIGS. Next, the locking member 36 is held over the opening / closing lid 11E and lowered in the direction of the arrow in FIG. 23, and the horizontal piece 36a is fitted into the guide cutout 35a. Then, the locking piece 36b is rotated downward while pressing the horizontal piece 36a. As a result, the horizontal piece 36a and the locking piece 36b of the locking member 36 are brought into close contact with the guide cutouts 35a and 35b, respectively, and the locking protrusion 20 inside the locking piece 36b is in contact with the engagement of the container main body 12 facing this. It slips into the lower surface of the stop edge 25.

  Therefore, in a state where the locking member 36 is fitted to the container main body 12 via the opening / closing lid 11E, the opening edge of the container main body 12 is further abutted against the seal packing 24 on the lower surface of the opening / closing lid 11E. Therefore, the seal packing 24 is pushed by the opening edge of the container main body 12 to bend and deform, and the opening / closing lid 11E seals the opening of the container main body 12 through the seal packing 24 as shown in FIGS. Close up. Thereby, it can seal so that the side dish in the container main body 12, the smell of soup, etc. may not leak outside.

  On the other hand, in order to remove the opening / closing lid 11E from the container body 12, the lower edge of the locking piece 36b of the locking member 36 is lifted with a fingertip. As a result, the locking projection 20 of the locking member 36 is forcibly removed from the lower surface of the locking edge 25 of the container body 12, and the locking piece 36b is flipped up outward. At this time, the repulsive force of the seal packing 24 is also applied, and the entire opening / closing lid 11E slightly floats above the opening edge of the container body 12 at this portion.

  Thus, by pulling the opening / closing lid 11 </ b> E upward from the container body 12, this engagement state is canceled and the opening of the container body 12 is opened. Therefore, stored items such as prepared foods in the container body 12 can be taken out. Similarly to the above, the opening / closing lid 11 opens the opening of the container body 12 by a simple operation of lifting the locking member 36 with a finger. Can do.
