Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container with a lid used as a food storage container or a lunch box for storing and preserving food.

[Prior art and its problems] Conventionally, in the case of containers of this kind, especially where the container body and the lid are made of synthetic resin molded products, a packing is used to maintain the sealing property when the lid is attached, and the lid is In many cases, a clasp is used to fasten the two bodies to the container body.

However, the stoppers in the conventional containers described above are only made by bending and forming metal wires such as steel wires, and as a result, there is a high risk of rusting during long-term use, which is a sanitary issue. Not only is this undesirable, but bent molding does not provide a fastener with high dimensional accuracy, and it is relatively easy to deform, leading to problems such as a weakening of the clamping force and a decrease in sealing performance.

Therefore, the present inventor proposed a container as shown in Utility Model Publication No. 59-43233. However, in this container, a protruding edge is provided on the peripheral edge of the lid body, holes are formed on both sides of the protruding edge, and the end of a locking tool formed in the shape of a synthetic resin is rotatably fitted into the protruding edge. It is a combination of Therefore, during this fitting, it is necessary to use the elasticity of the locking tool to forcefully fit it into the hole in the lid body, which may cause the locking tool to be damaged. Fitting is troublesome, workability is poor, and costs are high. Furthermore, since a protruding edge is provided on the peripheral edge of the lid and the locking tool is fitted into the protruding edge, there is a problem in that this part protrudes and the overall appearance of the container becomes unsightly.

The purpose of this invention is to improve the fastening and sealing performance between the lid and the container body when the lid is attached, to be hygienic and have a good appearance, and to be able to be easily installed without damaging the locking device, which has the drawbacks mentioned above. The purpose of the present invention is to provide a container that can solve this problem.

[Means for Solving the Problems] In order to solve the above problems, the present invention consists of a container body made of synthetic resin and a lid body made of synthetic resin, and the container body has an upper end portion of its peripheral wall. A flange that protrudes outward is provided slightly below the lid, and the lid body is
A main plate having a recess at a position corresponding to the upper end of the peripheral wall of the container body, an outer frame formed separately from the main plate and covering the upper surface periphery of the main plate, and a main plate and the outer frame provided at opposing positions of the lid body. It consists of a locking tool which is rotatably held by the main plate, and a gasket made of an elastic material is attached to the recessed part of the main plate, so that the locking tool can be freely locked to the flange of the container body.

[Function] In the container according to the present invention, the concave portion of the main plate of the lid body with the gasket attached is aligned and placed on the upper end of the peripheral wall of the container body, and the locking tool is rotated downward to lock the container body. By bringing the top surface of the protrusion into contact with the bottom surface of the flange and locking it, the packing in the recess is resiliently and strongly pressed against the top end of the container peripheral wall, and the inside of the container is completely sealed. can be held.
Then, by rotating the locked locking tool upward, the lid can be easily removed from the container body.

[Example] An example of the present invention will be described below based on the drawings.

10 is a container consisting of a container body 12 and a lid 14.

The container body 12 is made of AS resin and has a cylindrical shape with a bottom, and the upper end 18 of the peripheral wall 16
An annular flange 20 projecting outward is provided slightly below the flange 20 .

The lid 14 includes a transparent main plate 24 having a recess 22 at a position corresponding to the upper end 18 of the peripheral wall 16 of the main body 12, an outer frame 26 that covers the upper peripheral edge of the main plate 24, and the main plate 24 and the outer frame 26. The locking member 28 is rotatably held by the locking member 28.

A packing 30 made of an elastic material is attached to the recess 22 of the main plate 24 of the lid 14, and the packing 30 is made of silicone rubber formed into an annular shape. In addition, Patsukin 3
As the material of 0, an elastic material such as soft resin or rubber may be used. Further, the shape of the packing 30 is not limited to the rectangular cross-section as shown in the figure, but a hollow packing 30 having a hollow cross-section may also be used. In the case of materials, it is economical as it requires less material, and by making the inside hollow, the packing 3
This improves the elasticity of the main plate 24 and makes it easier to fit the main plate 24 into the recess 22.

The main plate 24 is made of transparent AS resin, and as shown in FIG. 2, an outer wall 34 is suspended from the periphery of the circular upper plate 32, and a protruding edge 36 is formed at the lower end of the outer wall 34, which protrudes outward. An inner wall 38 is vertically provided at a required distance from the inner surface of the outer wall 34 to form the annular recess 22 . The outer periphery of this protruding edge 36 is a rectangular shape with each side curved outward.
A notch 40 is provided at both ends of the short side. A rod-shaped locking portion 52 of the locking tool 28 in the lid attached state, which will be described later, is located in this notch 40. Note that since the main plate 24 is transparent, the contents of the container 10 can be identified at a glance.

The outer frame 26 is made of AS resin and covers the periphery of the upper surface of the main plate 24, and has an outer periphery formed in approximately the same shape as the main plate 24, and a periphery of an annular plate 42 having a circular opening in the center. It is bent to form a hanging wall 44, and has a substantially L-shaped cross section. A locking recess 46 is provided at a position corresponding to the notch 40 in the protruding edge 36 of the main plate 24. It is wide and approximately L-shaped in plan. At this time, the protruding edge 36
The width of the notch 40 and the width of the opening 48 are formed to be substantially the same.

The locking device 28 is made of ABS resin, and rod-shaped locking portions 52 are protruded from the upper ends of both sides of a slightly curved plate-shaped operating portion 50, and the end portions 54 of the locking portions 52 are bent inward. The end portion 54 of this locking portion 52 is accommodated in the locking recess 46 of the outer frame 26. As shown in FIG. 2, the upper end of this operation part 50 is formed with a protrusion 56 that protrudes toward the container body 12 along the upper end. are formed so that the upper surfaces of the two come into contact with each other. Further, as shown in FIG. 4, the tip of this protrusion 56 is curved along the outer surface of the main body peripheral wall 16, so that the locking tool 28 can be properly locked when the container 10 is sealed. .

In addition, the container body 12, the main plate 24, and the outer frame 26
are made of AS resin, and the locking tool 28 is made of ABS resin to increase its mechanical strength, but these are not limited to the synthetic resins mentioned above, and may include polyvinyl chloride resin, acrylic resin, polycarbonate resin, etc. It can be implemented using hard synthetic resin.

When assembling this lid body 14, the locking part 52 end 5 of the locking tool 28 is inserted into the locking recess 46 of the outer frame 26.
4 is housed, and the notch 40 provided on the protruding edge 36 of the main plate 24 is aligned with the opening 48 of the locking recess 46, thereby fixing the main plate 24 and the outer frame 26. At this time, the locking tool 28 cannot be removed from the locking recess 46 of the outer frame 26 in a state where it is held between the main plate 24 and the outer frame 26, and the locking tool 28 cannot be removed from the locking recess 46 of the outer frame 26, and is tilted downward by about 90 degrees from the horizontal position on the top surface of the lid body 14. It can be rotated. Then, the packing 30 is attached to the recess 22 of the main plate 24.

Next, the usage state of this container 10 will be explained with reference to FIG. 2. When the lid 14 is attached to the container body 12 to seal the inside, the lid 14 is attached to the upper end 18 of the peripheral wall 16 of the container body 12. Align and place the recess 22 on the main plate 24 with the gasket 30 installed, rotate the locking tool 28 to the state shown by the solid line in the figure, and place the locking tool 28 on the lower surface of the flange 20 of the container body 12.
The upper surface of the protrusion 56 is brought into contact and locked. At this time, the packing 30 in the recess 22 is resiliently and strongly pressed against the upper end 18 of the container peripheral wall 16, and the inside of the container is kept completely sealed. Conversely, due to the elastic force of the packing 30, the locking state of the locking member 28 to the flange 20 of the container body 12 is strong and secure, so that the container body 12 and the lid 14 do not easily separate. Well, the inner wall 3 formed on the main plate 24 of the lid body 14
Since the container 8 is extended downwardly from the outer wall 34, the recess 22 of the lid 14 and the upper end 18 of the container peripheral wall 16 can be aligned very easily.

Conversely, when removing the lid body 14, the locking tool 2
By rotating the lid 8 upward from the solid line in FIG. 2 to the position shown by the two-dot chain line, the lid 14 can be removed from the container body 12 very easily.

In the above embodiment, since the container body 12 is formed into a cylindrical shape, the lid 14 can be attached in any direction. however,
The container 10 of the present invention is not limited to such a shape, but may be a rectangular container 10 as shown in FIG.
It can also be applied to In this case, as shown in the drawings, the flange 20 of the container body 12 is provided with a notch 60, in which the rod-shaped locking portion 52 of the locking tool 28 is positioned when the lid is attached. . Further, if a partition plate 58 is arranged inside the container main body 12, it is suitable as a lunch box.

In each of the above embodiments, two locking devices 28 are attached to the lid 14, but depending on the size and shape of the container 10, the number of locking devices 28 may be increased as appropriate.

[Effects of the invention] As is clear from the above description, in the present invention, since the locking tool is rotatably held between the main plate and the outer frame, the elasticity of the locking tool can be reduced unlike the conventional one. There is no need to forcefully fit the lid into the hole of the lid, the lid can be easily attached without damaging the locking tool, and the lid can be manufactured at low cost with good workability. In addition, there is no protruding part on the periphery of the lid, and the locking tool in the lid-attached state is located below the periphery of the lid, so this part does not protrude and the overall appearance of the container is good. It is not bulky and can be easily stored in a bag.

In addition, since the locking tool is made of synthetic resin, it will not rust even after long-term use, which is good for hygiene, and it can be easily manufactured with high dimensional accuracy by molding. Moreover, it is difficult to deform, and there is no possibility that the tightening force will weaken and the degree of sealing will deteriorate.

Therefore, it is possible to provide a container that has good fastening and sealing properties between the lid and the container body when the lid is attached, is hygienic and has a good appearance, and can be easily attached without damaging the locking tool.
