Abstract

PURPOSE:To seal off an offensive odor from inside and also make a lid easily undetachable, by providing two magnetized bodies consisting of a belt-shaped rubber magnet, one on the opening end of a container and the other on the corresponding portion of a lid and producing an attracting force therebetween with their different poles facing each other. CONSTITUTION:Magnetized bodies 13a and 13b consist of belt-shaped rubber magnets which have a large amount of a highly magnetic metallic powder contained in the rubber and are magnetically stabilized by application of a high voltage and which are so arranged as to bring their north and south poles into contact. The magnetized bodies 13a and 13b are so arranged as to confront their north and south poles each other. These magnetized bodies are formed into a ring-shaped configurations with their diameters slightly larger than those across the side faces 111b and 121b of the recesses 111 and 121 of a container 11 and a lid 12 and bonded with an adhesive agent to the flat faces 111a and 121a of the recesses 111 and 121 in such manner that such magnetized bodies are pressed against the side faces 111b and 121b of the recesses 111 and 121. The interference fit thus created results in a film attachment and hence a high sealability between the container and lid.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a container with a lid used for various purposes such as for food and drinks, waste saving, and even for medicine. This invention relates to a container with a lid that has an extremely high degree of airtightness, and a method for manufacturing the same, in which N-S are placed adjacent to each other, and different polarities can be attracted to each other by strong suction.

(Prior art) Conventionally, commonly used containers with lids have a shape in which the opening of the container body and the attachment part of the lid are fitted with uneven parts provided therein, so that the lid does not close properly. It comes off easily, and
If something with a strong odor is stored inside the container, it will leak outside and become unpleasant, thus limiting the uses of containers with lids.

Therefore, the inventor of the present application previously created a closed structure of a container with a lid in Utility Application No. 58-173590, that is, the container body was formed of ceramics or the like, and the opening of the container was made of magnetic material as a donut plate-shaped magnetic rubber body. Alternatively, the main body of the container may be made of a magnetic material, the lid may be made of plastic, and a rubber magnet may be disposed on the abutting plane of the lid to allow attraction. Furthermore, the container body and the lid are made of ceramics, glass, etc., and powdered permanent magnets are mixed in the opening of the container body and the contact of the lid attached to the opening of the container to create a magnetized structure. was proposed to solve the above-mentioned conventional problems, but there was a limit to the magnetic force, so a strong sealing structure was used to block unpleasant odors from inside, and it was easy to handle the compost, but the lid was easy to remove. There is a strong desire for something that does not come off, can be applied to a variety of things, and is easy to manufacture.

(Problems to be Solved by the Invention) Therefore, the present invention has been made in order to eliminate the drawbacks of the prior art. It is made of any material to ensure strong sealing of these abutting parts, making it easy to handle and manufacture, and does not reduce the sealing function even if the lid is opened and closed repeatedly. The object of the present invention is to provide a container with a lid suitable for storing things, and a method for manufacturing the same.

(Means for Solving the Problems) That is, the first aspect of the present invention is to provide an opening end of a container body and a facing portion of a lid formed to match the opening end.

A container with a lid, in which a magnetized body consisting of a band-shaped rubber magnet with N and S poles arranged adjacent to each other is arranged so that different polarities can be attracted together, and a lid body is formed to be able to be opened and closed. providing step notches at the open end of the container body and the facing portion of the lid formed to match the open end, and then applying an adhesive to at least one flat surface of each step notch, Furthermore, in order to fit snugly into the step notch, the outer diameter of a magnetized body consisting of a band-shaped rubber magnet with N and S poles arranged adjacent to each other is shaped into a ring shape that is slightly larger than the outside diameter of the step notch. This is a method for manufacturing a container with a lid that is fitted and fixed.

(Function) Adhesive is applied to each of the flat parts of the open end of the container body and the recessed part of the lid formed to match the open end, and then the ferromagnetic metal is A large amount of powdered barium ferrite is blended into rubber, the magnetization is stabilized in a strong electric factory, and a magnetized body is made by arranging the N-S poles of a band-shaped rubber magnet adjacent to each other, with a diameter slightly larger than the outside diameter of the stepped part. By making it into a ring shape and fitting and fixing it into each of the step notches, a magnetized material is placed at the open end of the container body and a location opposite thereto, and by the attraction of the magnetized material, the container is closed. It is not possible to firmly attach the lid to the open end of the main body or open it, and N-5
Since the poles are arranged adjacent to each other, the adhesion is strong and the outside air is reliably isolated, so that the stored items are not affected by the outside air, and the odors of the stored items do not escape to the outside. moreover,
Since the magnetized material is firmly attached to the step notch, odor does not come out from this part, and it does not come off even if the lid is opened and closed frequently, making it possible to maintain a secure fit for a long period of time. It is.

(Example) In order to further clarify the gist of the container with a lid and the manufacturing method thereof of the present invention, an example will be described below using one drawing.

The lidded container 1 consists of a container body 11, a lid 12, and a magnetic material 13, and the container body 11 is made of ceramic, plastic, or glass, and can store food such as pickles, garbage, medicine, etc. and a stepped portion 11 formed at the upper opening end, which includes a flat portion 111a, a side surface portion 1itb, etc.
1 is recessed.

The lid body 12 is made of ceramics, plastics, glass, etc., like the container body 11, and has a flat part 121a and a side part 12i at a position matching and facing the step notch part 111.
A step notch 121 such as b is provided in a recessed manner, and a knob 122 is further protruded from the top.

The magnetized bodies 13a and 13b are band-shaped rubber magnets in which a large amount of ferromagnetic metal powder barium ferrite is blended with rubber, magnetization is stabilized under a strong electric factory, and N-S poles are arranged adjacently. The magnetically charged body 13a and the magnetically charged body 13b are N-
S's opposite comrades are arranged to face each other in a well-formed manner.

The magnetically charged bodies 13a and 13b formed in this way.

The side surface portions 111b and 121b of the stepped portions 111 and 121 of the container body 11 and the lid body 12 are formed into a ring shape with a hole slightly larger than the diameter, and then the flat portion 111 of the stepped portions 111 and 121 is formed into a ring shape.
a, 121a through any adhesive capable of adhering the magnetized bodies 13a, 13b, and the stepped portions 111, 1
The side portions 111b and 121b of 21 are fixed in a biased manner so as to be firmly disposed.
Since the south poles are adjacent to each other and face each other, the airtightness is much higher than that of simply arranging magnets.

In the present invention, the materials used for the container body and lid are ceramics, plastics, glass, etc.
The material used for the container body and lid of a container with a lid may be wood, paper, new ceramics, etc. Furthermore, the shape of the container body and lid, or the mounting means for fitting and removing the lid, etc. The magnetized structure may be arbitrarily determined within the range in which the above-mentioned objects and effects of the present invention are achieved, and the magnetized structure is not limited to the above-mentioned embodiments. , even after various changes,
It goes without saying that these changes do not change the gist of the present invention.

(Effects of the Invention) As described above in detail, the present invention provides a magnetic strip made of a rubber magnet or the like having magnetic pole action in two directions, with a hole slightly larger than the diameter of the stepped portion of the container body and lid. , and the magnetically charged body is inserted into the step notch, and the magnetically charged body is also inserted into the step notch of the container body, so each magnetic body has two directions of magnetic pole action, which is different from the conventional method. Compared to magnets and magnetic rubber bodies with magnetic field lines in only one direction, the outstanding magnetic force creates a strong attraction at each contact area, making it possible to ensure a reliable seal. Even when storing items with strong odors such as pickled vegetables and whose quality can easily change,
It does not dissipate odor outside the container and cause discomfort, prevents insects from entering from the outside due to lack of sealing, and does not cause spoilage or quality deterioration.
It is highly effective when used as a sealed container for various purposes, and
During manufacturing, the magnetized body is formed into a hole slightly larger than the diameter of the step notch in the container body and lid, so when the magnetized body is inserted into the step notch, the magnetized body tends to protrude outward. The stress acts on the magnetic material, which saves the trouble of pasting the magnetic material as in the past, and makes the gluing work easy.
Because it is easy to manufacture and can be firmly attached, there is no risk of it falling off even when the lid is opened and closed many times, making it extremely durable, and due to its outstanding magnetic effect. This provides suction power, etc.

As will become clear from the above description, the present invention can very simply and effectively improve the aforementioned problems that have arisen with conventional containers with lids, so the practical benefits brought about by the present invention are significant. I have to say it's big.
