Description of the Related Art Various airtight containers have been proposed that are provided with fitting recesses and are intended for accommodating objects such as vegetables or fruits.
As an example of these, for example, Utility Model No. 60-92959
There is something disclosed in the specification of No. The container represented by this invention has a fitting protrusion on the container body side and a fitting groove on the lid side, and a sealing protrusion on the side of the fitting protrusion. By forming a sealing groove that fits into the sealing groove provided on the side of the fitting groove on the facing side of the fitting groove, the fitting groove and the fitting groove can be fitted and locked to each other. In addition, the sealing protrusions and the sealing grooves are fitted into each other to provide an engaged relationship and a sealed state between the two members.

[The problem that the idea aims to solve]

However, the fitting of the fitting protrusion and the fitting concave line in such a container is easy if the sealing convex line and the sealing concave line are formed with precise precision. Since these sealing protrusions and sealing grooves have been previously formed, errors in the formation of the sealing protrusions and sealing grooves may cause damage to the vegetables, fruits, etc. stored in the container body. If the convex and concave lines for both seals are not completely fitted when the lid is pressed and fitted to the container body due to the amount of Failure to do so may cause problems. Furthermore, when these parts are molded with foamed beads, problems tend to occur particularly in terms of accuracy, and a situation arises where it is not possible to completely maintain airtightness during use.

The container according to the present invention was devised in view of these conventional problems, and the purpose is to provide a strong engagement relationship and a perfect sealing state in a container consisting of a foamed synthetic resin container body and a lid. shall be.

[Means to solve the problem]

In order to achieve such an object, claim 1 of the present invention consists of a container body and a lid made of foamed synthetic resin, and a fitting protrusion is provided around the upper end of the side wall of the container body, and the outer periphery of the lid is A fitting concave line is provided around the lower surface to fit with a fitting convex line provided on the container body side,
Moreover, when the mating protrusion and the mating concave strip are fitted, the mating convex strip and the mating concave strip are provided in a positional or sized relationship such that a mating interval is formed between the facing sides of the two, A container was constructed in which a plurality of sealing protrusions having a height higher than the width of the fitting gaps were provided at different height positions on the side surface facing the fitting gaps of the strips.
In addition, claim 2 provides that the sealing protrusions are provided at different height positions on the side surfaces of both the fitting convex line and the fitting concave line facing the fitting gap; In each example, the sealing protrusions are provided at different height positions on the side surface facing the fitting gap of one of the protrusions and the fitting grooves. In claim 4, the container body and the lid body are separately made of foamed synthetic resin, and a fitting protrusion is provided around the inner side of the upper end of the side wall of the container body, and on the lower surface of the outer periphery of the lid body on the side of the container body. A fitting concave strip which is open downward and engages with a mating convex strip provided in When the concave grooves are fitted, the positions and sizes are such that a fitting gap is formed between the facing outer and inner surfaces of the two, and both sides of the concave fitting groove and the concave fitting groove are provided. A container was constructed in which a sealing protrusion having a total height greater than the total width of the fitting gap was provided on one of both sides of the container. Furthermore, in claim 5, one of the plurality of sealing protrusions is provided on the tip side of the side surface of the fitting protrusion or on the opening side of the side surface of the fitting groove.

[Effect]

In such a container, since a plurality of sealing protrusions are simply provided on the side surface facing the fitting gap between the fitting protrusions and the fitting grooves, the fitting protrusions and the fitting concave By fitting the strips into each other, the sealing convex strip concavely deforms the target surface in contact with it, resulting in a concave sealing strip, which enhances the sealing effect of both parts, and at the same time creates a gap between the two parts. Even if the position changes up and down each time it is used, the grooved grooves for sealing are recessed and recessed on the target surface to which the protruding sealing stripes come into contact, making it possible to provide a perfect sealing condition inside and outside.

〔Example〕

The details of the container according to the present invention will be further explained based on the attached drawings. In the figure, 1 is a container body made of a foamed synthetic resin such as foamed polystyrene, foamed polyethylene, foamed polyurethane, etc., for accommodating objects such as vegetables or fruits, and a fitting protrusion 3 is provided on the inner side of the upper end of the side wall 2. There are surrounding areas. The lid shown as 4 in the figure that closes the container body 1 has a fitting concave line 5 that is open downward and that fits with the fitting convex line 3 provided on the container body 1 side on the lower surface of the outer periphery. It is set up. As shown in FIGS. 2 and 3, this fitting groove 5 has a grooved outer wall 6 provided around the outside of the lower surface of the outer periphery of the lid body 4, and a grooved groove on the inside spaced apart from the grooved outer wall 6. By providing the inner side wall 7 around the strip, it is formed between the two as a result.

The fitting protrusion 3 and the fitting groove 5 are shown in FIG.
In the case shown in Fig. 3, when it is fitted,
That is, when the container body 1 is closed with the lid 4, there is a fitting gap between at least the outer surface on the left side in the drawing of the fitting protrusion 3 and the outer surface on the left side in the drawing of the fitting groove 5, which face each other. are provided in a positional or sized relationship such that In order to seal this fitting gap, the fitting protrusion 3 and the fitting concave line 5 are used.
This is achieved by protruding sealing protrusions 8 whose height is higher than the width of the plurality of fitting gaps at different height positions on the side surface facing the fitting gaps. First, as shown in FIG. 2, one sealing protrusion 8 is provided around the distal end side of the outer surface of the fitting protrusion 3 and on the opening side of the outer surface of the fitting groove 5, respectively. In this case, if the fitting protrusion 3 and the fitting groove 5 are fitted,
The sealing protrusion 8 is force-fitted while pressing the side surface that comes into contact with it, and as shown by the dashed line in the figure, the target surface that comes into contact with it becomes concave, and as a result, the sealing protrusion 8a is caved in.
In this way, the container main body 1 and the lid body 4 are not only engaged by the fitting relationship between the fitting protrusion 3 and the fitting groove 5, but also the side surface that is in contact with this sealing protrusion 8. A mutual engagement relationship and a perfect sealing state are provided by the frictional resistance between them and the engagement relationship between this and the seal groove 8a formed by concave deformation. In the case shown in FIG. 2, the fitting protrusions 3 and the fitting grooves 5 cannot be completely fitted unless each of the sealing protrusions 8 crosses over the other and is fitted. The respective sealing protrusions 8 mutually act as members that prevent the lid 4 from separating from the container body 1. Next, the third
In the figure, two sealing protrusions 8 are provided around the outer surface of the fitting protrusion 3 at different height positions, that is, at different positions on the distal end side and the proximal end side. In the structure shown in FIG. 3, the insertion operation is easier than in the structure shown in FIG. 2, and even if the sealing protrusion 8 is used repeatedly, it is less likely to be damaged, deformed, etc. and become lower.

4 and 5 show sealing protrusions 8 provided at different height positions on both sides of the fitting protrusion 3 and at the same height position, respectively. In this case, the fitting groove 3 and the fitting groove 5 are similar to the case where the sealing groove 8 is provided on both sides of the fitting groove 5, but when they are fitted, the two face each other. Between the outer surface of the fitting protrusion 3 on the left side in the drawing and the outer surface of the fitting groove 5, also on the left side in the figure, and between the right inner surface of the fitting protrusion 3 and the fitting groove 5 in the same figure. They are provided in a positional or sized relationship such that a fitting gap is formed between the inner surfaces of the middle right side. The total height of these sealing protrusions 8 is greater than the total width of the fitting gap. These Figure 4,
In the case shown in FIG. 5, since the sealing protrusions 8 are provided on both sides of the mating protrusion 3, the engagement relationship between the mating protrusion 3 and the mating concave strip 5 is strong, and the sealing portion against the container is are formed on the inside and outside to achieve a more complete seal.

Moreover, what is shown in FIG. 6 is a modification of the one shown in FIG. 3, in which two sealing protrusions 8 are provided around the outer surface of the mating concave strip 5 at positions shifted from the opening side to the bottom side. This is what I did.

Furthermore, what is shown in FIGS. 7 and 8 is the fourth
This is a modification of the one shown in FIG. 5, in which sealing protrusions 8 are provided at different height positions on both sides of the fitting groove 5 and at the same height position.

In such a container, when the lid 4 is applied to the container body 1 and pressed, the fitting protrusion 3 and the fitting groove 5 fit into each other, and the container is closed. Since the height or the total height of the sealing protrusion 8 is higher than the width or the total width of the fitting gap, the fitting protrusion 3 is pushed against the fitting groove 5 while receiving some resistance.
The sealing protrusion 8a concavely changes the target surface that comes into contact with it, and as a result, the sealing protrusion 8a
The container is recessed to form two sealed portions that are shifted in position to provide a sealed condition to these containers. At the same time, the insertion position of the fitting protrusion 3 into the fitting concave line 5 is adjusted depending on the amount of vegetables or fruits stored in the container body 1 during use, and the fitting depth at the time of fitting. Even if there are various changes due to
Since the seal grooves 8a are independently formed on the surfaces to which the seal protrusions 8 come into contact, the desired sealing condition can always be achieved. If one of the plurality of sealing protrusions 8 is provided on the tip side of the side surface of the fitting protrusion 3 or on the opening side of the side surface of the fitting concave line 5, the sealing protrusion 8 can be provided until just before the lid is completely closed during the lid closing operation. The sealing protrusion 8 comes into contact with the target surface to maintain a sealed state.

[Effect of idea]

In the container according to the present invention as described above, the insertion position of the fitting convex line with respect to the fitting concave line is determined depending on the amount of vegetables or fruits stored in the container body during use, and the fitting position at the time of fitting. Even if the depth varies, each sealing protrusion is formed independently on the target surface that the sealing protrusion comes into contact with, so it is always possible to maintain a strong engagement relationship and at least a good position between the container body and the lid. A complete seal is achieved by means of two offset sealing parts. Furthermore, during the lid closing operation, at least the sealing ridges simply contact and slide on the side facing the fitting gap between the fitting ridges and the fitting grooves, so there is no space between the container body and the lid. Although a strong engagement relationship and a perfect seal are achieved,
It's easy to do. Furthermore, from these reasons,
Although it can be expected to have the same or better effect than when the mating convex strip and the mating concave strip are in a tight mating relationship, there is less damage to the component parts.
Can be used for a long time.
