Description

[Detailed description of the invention] This invention has a lid engagement structure using a permanent magnet, in particular, a permanent magnet that engages all or part of the curved corner of the rising peripheral wall of the container body. The present invention relates to a container structure in which bulging of a magnet mounting portion toward the inside of the container is avoided as much as possible.

Conventional container lid engagement structures using this type of permanent magnet generally consist of a structure in which a permanent magnet is attached approximately to the center of the front rising wall of the container, and this front rising wall There are many difficulties in attaching permanent magnets due to the relatively thin structure and the fact that when a permanent magnet is assembled within this rising wall, the rising wall becomes extremely fragile. This is what I did.

From this point of view, in conventional cases, when attaching a permanent magnet to a rising wall at the front of a container, a part of the wall surface is generally made thick, and in particular, the wall surface is expanded inward, and this expanded thick part is thickened. A permanent magnet and a yoke are embedded in the magnet.

However, in this method, a bulge corresponding to the size of the permanent magnet attached must be formed on the inside of the container, which is a major drawback in the use of the container. This inconvenience is especially noticeable when storing pencils, rulers, and other long items in the container.When the container is used as a pencil case, the voids on the sides of the raised portions are often It was left as an unused part.

In addition, containers such as pencil cases, which have traditionally been resin molded products, have fragile rising corners, which often causes tearing, distortion, or damage from the rising corners of the container during use. be.

The present invention was devised especially in view of the inconveniences in the conventional precedent, and the permanent magnet used for engagement is provided particularly on the rising wall of the corner portion of the container body, and the permanent magnet is provided on the rising wall of the corner portion of the container body, and By using this permanent magnet, it is possible to sufficiently reinforce this part, which is considered to be relatively weak, and also to eliminate the problem of inner expansion bulges on the rising wall,
This allows the entire inner surface of the container to be used completely.

In addition, the method of attaching the permanent magnet used is to make the front part of the container the same thickness as the wall surface constituting the container, to eliminate the bulge of the engaging member in the conventional example, and to make the front part of the container completely flat. In addition to having a nice appearance, it is possible to use magnets with a suitable large capacity, and it is possible to easily attach the necessary engaging magnetic force magnets.

Furthermore, the edge of the container lid which is intended to abut against the corner portion of the container body is generally made into the corner portion of the lid plate in correspondence with the body, and by attaching and fastening a ferromagnetic plate to this portion, tearing, breakage, distortion, etc. at the corner edge of the lid plate is almost completely avoided.

In order to realize various desired effects of these characteristics, the present invention particularly focuses on a container body with an open top, and a cover connected to the container body and over the opening of the container body. In a container consisting of a container lid made of a synthetic resin or other material, all or part of the corner of the rising peripheral wall of the container body is cut out, and a flat L-shaped or arc-shaped permanent magnet is arranged in the cut-out rising corner. In addition, a ferromagnetic plate attached to the container lid that abuts the upper surface of the rising peripheral wall is placed at a point where it can be detachably attached to the permanent magnet.

Further, the present invention is based on the gist of the above-mentioned configuration, and includes the following specific embodiments and considerable design changes associated with these embodiments.

The details of the present invention are shown in the drawings below. A typical embodiment of the invention will be described with reference to the most basic pencil case. 1 is a dish-shaped container body provided by vacuum molding or other methods. , which has an external shape, dimensions, and internal materials that suit the purpose.

Next, 2a is a lid plate for closing the upper opening of the container body 1, and is designed to have an appropriate shape and size to match the closing part of the container body 1. A back plate 2c is configured to fix the container body 1 to one end surface 2b of the base plate 2, which is continuous through the edges 2', 2', and corresponds to the rising dimension of the rising peripheral wall 1a of the container body 1. The lid plate 2a can be freely folded over the opening from the upper edge of one side of the rising peripheral wall 1a of the container body 1 through the opening.

The relationship between the lid plate 2a and the main body 1 is not limited to the above-mentioned embodiments, and as long as the lid is closed over the opening of the main body 1, the attached structure as such a folding piece is possible. Of course, if the lid is to be used as a lid, a lid body or the like is intended to be used as a separate piece from the main body 1 for closing.

In addition, the shape of the container body 1 is not limited to such a rectangular dish shape, but an elliptical dish shape and other polygonal dish shapes are planned. It is.

Furthermore, as already mentioned in the above, it goes without saying that the container to be implemented is not limited to a pencil case, but is expected to be widely used for general jewelry boxes and other small container containers. It is something.

Permanent magnets 3 having a planar L-shape are disposed at both front corner portions of the rising peripheral wall 1a of the container body 1, and a specific example of their installation is shown in Fig. 2. In addition, as is clearly seen in FIG. 3, the inner and outer end surfaces of the permanent magnet 3, which is approximately L-shaped, are used as magnetic poles, and a rising peripheral wall 1a is formed.
It is arranged so that it is integrated with the

Ferromagnetic plates 4,
4 is attached and attached for engagement with the magnets 3, 3.

The embodiments described above are based on the existence of a foldable lid plate 2a, but in the case where a removable lid plate is used and the container body 1 is in the shape of a pentagonal or larger plate. The number of corner parts where the magnets 3 should be arranged is further increased, and it is planned to arrange the magnets 3 at all corner parts as necessary.

In addition, instead of the embodiment described above, the magnets 3 in the container body 1 having an oval dish shape are provided with magnets 3 having a planar arc shape that matches the curved edges on both sides, and similarly, magnets 3 are arranged in the curved portions on both sides of the rising peripheral wall 1a. It was designed so that the

The present invention is intended to achieve specific effects of the above-mentioned characteristics through the characteristic configuration described above. First, the thick part for attaching the magnet 3 is expanded inwardly of the container body 1. This eliminates the need for any unused parts on the inner surface of the container main body 1, and eliminates any structure that may hinder the use of the inner surface of the container body 1.

In addition, the engaging member is provided at a corner portion that is usually located on the side, and the front surface of the device is designed to have a clear appearance, thereby avoiding the bulging of the engaging member in the conventional example and increasing the capacity of the container. The engagement force is increased by magnetically attaching the material to the material. In particular, the magnetic adhesion on both sides of the lid plate 2a or the lid plate 2a
This is more effective in cases where the lid plate 2a is weak, and can prevent the contents stored inside from being unexpectedly lost due to the lid plate 2a sagging.

Furthermore, such magnetic adhesion on both sides of the lid plate 2a
This effectively avoids the application of a lever-like external force from the side, and reliably prevents the magnetically attached surface from detaching, which is a relatively difficult problem.

Furthermore, by attaching the magnets 3 to such corner portions, the magnets used can be of any size, making it possible to selectively use permanent magnets 3 having the desired magnetic capacity. It is.

Furthermore, the greatest advantage of providing the magnets 3 at such corner portions is that the strength of the corner portions of the upright peripheral wall 1a, which are particularly vulnerable in the container body 1, can be increased, and other vessels It was able to function as a bone at the corner portion where external forces such as collision, pressure, abrasion, and tension are likely to occur.

From this point of view, tear damage, distortion, etc. that often occur at corner portions can be reliably avoided, the shape of the corner portion can be reliably maintained, and external force applied to the rising peripheral wall 1a surrounded by the corner can be reliably avoided. This is a relaxed version of the addition.

Also, by intervening the ferromagnetic plate 4, the lid plate 2a is
The edges are protected.
