Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an airtight container that can be used for lunch cases, vegetable containers, and other arbitrary purposes, and in particular, to airtight containers that can be used in combination with multiple container components. It concerns containers.

(Prior art) Airtight containers have a structure in which the main body and lid are tightly sealed with packing, and the lid is tightly tightened with a stopper to prevent juices from the contents from leaking out.
No. 43238, etc.).

(Technical issue) However, conventional airtight containers only consist of a container body and its lid, and in order to separate and store several types of items, it is necessary to use a combination of partition pieces and small containers that are placed inside the container body. There is the inconvenience of having to use multiple sealed containers at the same time. Furthermore, with conventional products, the content cannot be changed.

Therefore, the present invention constructs an airtight container from multiple containers, etc., and allows these components to be used as desired, making it possible to combine them according to the type and size of the items to be stored. To provide a combination airtight container that can be formed in plurality and whose contents can be varied.

(Technical Means) The object is to provide a lower container 3 which has a container shape and is open from the top and has locking edges 2, 2 on the outsides of its opposing side walls 1, 1; When stacked on the lower container 3, the opening edges 9a, 9a rest on the locking edges 2, 2 of the lower container 3 to close the opening 4, and a sealing member 6 is attached along the inner corner corresponding to the bottom of the container. It has a cover 9 that opens downward and has a size that can be interposed between the lower container 3 and the cover 9 to close their openings, and has an opening edge 4 of the lower container 3 on one side.
It has a sealing member 10 in contact with a, and has a protrusion 11 on the other side that engages with the inside of the opening edge 9a of the cover 9, and further has a protrusion 11 on the opposite side 12, 12 that is in contact with the locking edge 2, 2. Locking edge 1 provided corresponding to
3 and 13; an upper container 15 that is open from the top and has a container shape and whose opening edge 15a contacts the sealing member 6 of the cover 9 when placed on the inner lid 14; engaging portions 17, 1 which are rotatably supported on the outside of the opposing side walls 16, 16 and engage with the two locking edges 2, 2, 13, 13;
7, 18, and 18, the lower container 3 is sized to fit in the cover 9, and the upper container 15 is sized to fit in the lower container 3, respectively.

(Embodiment) The illustrated embodiment relates to a square sealed container having a rectangular planar shape, and the lower container 3, cover 9 and upper container 15 have sloped side walls, and the opening is larger than the bottom. The lower container 3 has a locking edge 2 projecting outward from the top in a band shape on the opposing side walls 1, 1, and a bulge 2a is provided at the tip of the locking edge 2. , used as the main container part.

The cover 9 covers the opening 4 of the lower container 3 at the largest among the constituent containers.
It has a larger opening, and its opening edge 9a can rest on the locking edges 2, 2 to close the lower container opening 4 (see Fig. 4), and a Packing made of foamed synthetic resin is fitted into the groove 5 between the protrusion 5a and the side wall as a sealing member 6, and an appropriate number of ventilation holes 8 are opened in the circumferential side 7, and the cover top is closed. A pore 21 is opened in a concave portion 20 provided in the plate portion, and a cross section of approximately I is formed therein.
A ventilation push button 22 is fitted in the shape of a square.

Reference numeral 23 denotes a pair of engagement pieces protruding from the outside of the opposite side walls 16, 16 of the cover 9, and 24 indicates a bearing groove formed in the engagement pieces 23, which rotatably pivot the shaft portion 25 of each stopper 19. support Reference numerals 26 and 26 indicate a pair of notches formed in the stopper 19 to provide the shaft portion 25, and 27 indicates an operating ridge provided at the end of the stopper 19. The stopper 19 is provided with two elongated holes parallel to each other as engaging portions 17 and 18, and the locking edge 2 of the lower container 3
can engage with any of the engaging portions 17 and 18. Inner lid 1
4 closes the opening 4 of the lower container 3 and is in contact with the opening edge 9a of the cover 9, and a sealing member 10 is provided on the bottom surface of the packing that is in contact with the opening edge 4a of the lower container 3.
It has a circumferential groove 30 partitioned by inner and outer circumferential walls 28 and 29 for fitting as a cover, and a cover opening edge 9a on the upper surface.
It has a protrusion 11 that allows the cover to loosen outwardly, and is further provided with a ventilation push button 22 similar to that provided on the cover 9. The mechanism of the push button 22 may be the same as described above. Further, on the sides 12, 12 of the inner lid 14, which correspond in position to the locking edges of the lower container 3, locking edges 13, 13 that protrude in a band shape are integrally provided. It can also engage with the engaging parts 17 and 18. 1
3a is a chamfered portion, which is formed slightly so as not to come into contact with the stopper 19 when engaged.

The upper container 15 is the smallest among the constituent containers, and when placed on the inner lid 14, the opening edge 15 is connected to the sealing member 6 of the case 9.
The opening edge 1 is kept in contact with the
5a fits inside the inner circumferential wall 28 of the inner lid 14 for stability (FIG. 3). Upper container 1
There are protrusions 31 in several places on the bottom of the bottom of 5.
A step 32 that engages with it is provided on the upper surface of the inner lid 14.

(Operation of the invention) Next, the operation of the invention will be explained with reference to combination examples. First, when using all the components, as shown in FIG. is engaged with the inner lid 14 and the lower container 3. At this time, the locking edge 2 of the lower container 3 is engaged with the outer engaging portion 17 of the stopper 19, the locking edge 13 of the inner lid 14 is engaged with the inner engaging portion 18, and the lower container 3 is engaged with the inner lid. 14 and the upper container 15 are sealed by the seal member 6 of the cover 9, so they are suitable for accommodating items that need to be separated, such as rice and greens. Since it is outside the airtight area, it does not affect the airtightness.

The example shown in FIG. 4 is a combination example in which only the lower container 3 and cover 9 are used.
Since the locking edge 2 can be engaged with the locking edge 2, the entire interior can be used, and since ventilation can be obtained through the ventilation hole 8, large items such as sandwiches and rice balls can be accommodated. In the example shown in FIG. 3, the lower container 3 is inverted and placed inside the cover 9, the upper container 15 is placed under it, the inner lid 14 is applied from below, and finally the locking edges 2, 13 are fitted. Because it is the smallest and most compact product that is integrated by engaging the stoppers,
It is convenient to keep all components together after use (after meals) or when not in use.

(Effect of the invention) Therefore, according to the invention, the cover 9, the lower container 3 that fits therein, and the upper container 15 that fits in the lower container 3.
, an inner lid 14 that can engage with the opening edge of the cover 9 and be interposed between the cover 9 and the lower container 3, and a stopper 19 that fixes them, and by combining these, two or more types of In addition to being able to separate and hermetically store items, it is also possible to store large items using only the cover 9 and the lower container 3, or to use all the components to minimize capacity and external size. , various combinations can be implemented depending on the application, and remarkable effects not seen in conventional closed containers can be obtained.
