Description

[Detailed description of the invention] The present invention relates to the invention of a container, which forms a stable support relationship even on a support surface with a certain degree of unevenness, and is capable of forming a stable support relationship with other objects in containers that use a container body formed with a bottom. This ensures a stable support relationship even in dynamic conditions due to contact between the two.

In containers, forming the bottom surface of the container body into a slightly arcuate curved surface makes it easier to mold the container body, makes it possible to manufacture a container body with the desired performance using a relatively thin layer of material, and It has been traditionally used in various general containers and pots due to its advantages such as increasing the pressure resistance of the container body and also improving the convection effect when heating the liquid stored in the container. Various methods are being adopted. However, a container whose bottom surface is formed as a slightly arcuate curved surface lacks stability when placed on a base plate, and the stability when placed in such a manner is poor. The best way to obtain this is to arrange three legs equiangularly with respect to the center of the support surface, even on slightly uneven support surfaces (including cases where there are foreign objects on a flat support surface). It is generally known that a stable and favorable support relationship can be obtained. However, in a case where the legs are arranged in an equiangular relationship on the bottom surface which has a somewhat arcuate curved surface, even if a stable support relationship could theoretically be formed even on a support surface having a certain degree of unevenness, the container In practical use, it is unavoidable that the device is not only in a static state, but also receives dynamic forces from the side by the operator or others, and in such cases, the support relationship is never stable. I learned that it wasn't something I did. In other words, it is clear that it is advantageous to form the arcuate curved surface with a certain degree of curvature in order to secure the above-mentioned merits. It is also clear that it is preferable to have the legs as low as possible, so in order for the bottom surface, which is an arcuate curved surface, to be supported so that it does not come into contact with the support and placement surface, it is necessary to have three relatively low legs. To some extent, the container has no choice but to take a position where they are gathered together at the center of the bottom, and if the container is supported by the three legs that are gathered to some extent at the center of the bottom in this way, it will fall over due to external force. There is no choice but to say that it is highly possible.

The present invention was devised after repeated studies in view of the above-mentioned circumstances, and the embodiment thereof is explained as shown in the attached drawings.
The bottom surface is formed with an arcuate curved part 11,
This arc-shaped curved surface may have the same radius of curvature over the entire bottom surface, but generally the radius of curvature is slightly larger at the center of the bottom surface, and the radius of curvature is gradually decreased as it approaches the periphery. None side wall part 12
The smallest radius of curvature is used at the boundary between the However, in the present invention, two sets of three legs each are used as the legs disposed on the bottom surface of the container body 1, the first set being two groups of relatively high main legs, The second set includes three groups of auxiliary legs that are formed at a lower height than the second set, and these two sets of legs are in an equiangular relationship with the center of the bottom of the container body.
That is, they are arranged at intervals of approximately 120°, and the auxiliary legs 3 of the second set are arranged at an approximately intermediate angular position of the main legs 2 of the first set. As shown, the legs 2 and 3 forming each group are spaced approximately 60 degrees apart. As shown in the figure, the legs 2 and 3 may be integrally formed by bulge molding during molding of the container body 1, but in some cases, separately formed leg pieces may be attached. Furthermore, the distances between the legs 2 and 3 from the center of the bottom of the container are generally the same as shown in Figure 2, but in some cases the distance between one of the leg groups may be slightly larger. You can pick it up. However, regarding the auxiliary leg 3, it is necessary to select a position outside the straight line connecting the main legs 2, 2. In the case shown in the figure, a lid body 4 is attached to the container body 1 by a seaming part, and an outlet body 5 is attached to the lid body 4 with a fastening material 6. However, these structures may be provided with a removable lid, or in some cases, the container may have only a container body without a lid. Further, the arcuate curvature of the bottom surface is not limited to that shown in the drawings, and any degree of curvature can be applied.

It is clear that, when the present invention is used as described above, the main legs 2 can always form a stable supporting relationship even on a supporting surface having some unevenness, just like the conventional three-legged arrangement, in a stationary state. Moreover, the container body 1 is not easily displaced by any external force.
When a lateral force acts on the vehicle from any direction, the auxiliary legs 3 effectively prevent the vehicle from falling over.
That is, in a dynamic state where this lateral force is acting, the direction in which the container body tends to tip over is substantially specified as the midpoint between the positions of the main legs 2 (a considerably large force is required to tip the container body in the direction in which the main legs 2 are arranged, and this is impossible, but it can be easily toppled in the midpoint direction with a light force). Therefore, even if the auxiliary legs 3 provided in this direction are somewhat low, they will adequately prevent the container body from tipping over.
This makes it possible to form a stable supporting relationship both in a static state and in a dynamic state when subjected to an external force.

According to the present invention as explained above, the main landing gear 2 can always form a stable support relationship even on a supporting surface having a certain degree of unevenness in a stationary state, and also in any direction in a dynamic state where external forces are applied. A stable support relationship can be formed by the auxiliary legs 3, that is, the characteristics of the small number of three main legs 2 can be fully provided, and the disadvantages thereof can be effectively eliminated, and each leg 2,
3 can be concentrated to a certain extent in the center of the bottom of the container, and therefore does not need to be very high, so that it is possible to prevent containers from falling over with a simple and good-looking structure. Since it is possible to form a stable supporting relationship, this is a highly effective idea in practical terms.
