Description

TECHNICAL FIELD The present invention relates to the structure of a hermetically sealed portion of a storage container for liquids and the like.

(Prior Art) When storing liquid materials, most of them are put in a glass or synthetic resin bottle container, and a metallic sealing lid called a so-called crown is used to keep airtightness and seal the opening. .

(Problems of the prior art) Since this kind of sealing lid is deformed at the time of opening, it cannot be reused as a sealing stopper for storing contents, and another lid or sealing stopper is required. In this case, for containers that are used as standard daily, a matching lid or stopper is available on the market, but due to the difference in the shape of the container opening, the lid or stopper may not fit. Many. Also, in the case of a metal container, a sealing member that utilizes the elasticity of metal is used as the lid, so it is easier to obtain airtightness for storage even after opening the container, compared to a container made of glass or synthetic resin. It is easy to be damaged, but requires a special structure.

(Object of the invention) Therefore, the object of the present invention, in the storage container such as liquid, by utilizing the attractive force and repulsive force of the permanent magnet,
It is an object of the present invention to provide a magnetic stopper that can easily open and close a container.

(Summary of the Invention) In order to achieve the object of the present invention as described above, a ring-shaped hole 12a is formed in the center so as to pass through the upper and lower surfaces, and a first permanent magnet is embedded in the inside of the container. A receiving portion 12 made of a synthetic resin attached to the inside of the opening, and a second portion which is located above the receiving portion 12 and has a repulsive position and a repulsive position with respect to the first permanent magnet by a rotation operation. A permanent magnet is embedded inside, and a lid 13 made of synthetic resin that is rotatable and a tubular shape having a hole 19a in the center are formed, and the upper end is inseparably connected to the lower surface of the lid 13 and closed. Together with the side surface, the receiving portion 1 is provided at a position where the lid portion 13 is pushed
2, a synthetic resin connecting portion 19 having a hole 19b which is closed at the side wall of the inner hole of the lid portion 13 and which is not closed at the rising position of the lid portion 13, and the lower end of the connecting portion 19 is integrally and integrally fixed and fixed. Has a through hole 18a communicating with the hole 19a of the connecting portion 19, and when the lid portion 13 is in the suction position with the receiving portion 12 by the rotation of the lid portion 13, the lid portion 13 repels the first permanent magnet. Provided is a magnet stopper, which comprises a lower lid part 18 made of synthetic resin having a first permanent magnet and a third permanent magnet for attracting when the receiving part 12 is in a repulsive position. To be done.

(Example) Next, the Example of this invention is described in detail using drawing.

FIG. 1 is a vertical cross-sectional view showing an embodiment of a magnet stopper according to the present invention, in which a ring-shaped receiving portion 12 having a hole 12a at the center is inserted inside the opening of a container 11 and is attached to the 12a. The lid portion 13 and the connecting portion 19 for connecting the lower lid portion 18 having the through hole 18a in the center are fitted so as to be vertically movable. The lid portion 13, the lower lid portion 18, and the connecting portion 19 have a horizontal H-shaped longitudinal section, and a hole 19a communicating with the through hole 18a is provided at the center of the connecting portion 19 from below to reach the upper lid portion 13. It is hollow, and a hole is provided in the radial direction in the upper part of the hole 19a so as to serve as a spout 19b for the contents of the container 11. As shown in FIG. 1, the receiving portion 12 is a synthetic resin molded product in which a permanent magnet 15 is embedded inside, the lid portion 13 is fitted with the permanent magnet 14, and the lower lid portion 18 is fitted with the permanent magnet 16. is there.

Next, regarding the magnetization of these permanent magnets, the permanent magnet 14 and the permanent magnet 1 are arranged so as to be magnetized to have the magnetic polarities shown in FIG. 16 is a permanent magnet 14 provided on the lid 13 as shown in FIG.
It is magnetized and arranged with a polarity opposite to that of.

The operation of this embodiment will be described. When the relative positions of the permanent magnets of the lid portion 13 and the receiving portion 12 are in the positional relationship shown in FIG. 2, as shown in FIG. , Receiver 1
Since the polarities of the two facing surfaces of the magnet 15 are different from each other, the lid portion 13 is attracted downward by mutual attraction force, and the container 11 is sealed. In this case, since the magnet 16 of the lower lid portion 18 has the same polarity as the magnetic pole of the facing surface of the permanent magnet 15 of the receiving portion 12, the forces that repel each other to lower the lower lid portion 18 are exerted. To support the sealed condition of.

Next, when the lid portion 13 is rotated 90 ° about the vertical axis as a central axis, the mutual positions of the permanent magnets of the lid portion 13 and the receiving portion 12 become as shown in FIG. Since the polarities of the receiving portion 12 facing the magnet 16 and the permanent magnet 15 are different from each other, the attraction forces act on each other and the lower lid portion 18 is attracted upward, and the state shown in FIG. 3 is obtained. Therefore, the spout 19b provided in the connecting portion 19 becomes an opening, and the content of the container can be spouted to the outside. Since the permanent magnets 14 of the lid portion 13 have the same polarity as the opposing magnet surfaces of the receiving portion 12, mutual repulsive forces assist the lid portion 13 in ascending and save the opened state.

Further, as shown in FIG.
If a guide groove 19c is carved obliquely on the rotating surface that contacts with 2, and the projecting member 12a is projected on the receiving portion 12 corresponding to the guide groove 19c, the connecting portion 19 rotates smoothly, and the sealing plug and It is possible to easily perform the opening operation.

(Effects of the Invention) As described in detail above, the present invention provides a hermetic stopper for a storage container,
Since the operation of opening and opening the cap uses the magnetic force of a permanent magnet or the action of repulsion, it can be performed completely by a slight rotation of the lid, etc., and the magnetic force is semi-permanent when the magnetic material used is selected. Can be held at. Further, even if the cap is opened from the closed state and resealed, no deformation occurs and repeated use is possible. Since the lid portion, the receiving portion, and the like are covered with a synthetic resin, the change with time is small, the stability is chemically high, and it is sanitary even when the food is sealed. Further, it is possible to take measures to prevent powder loss of the lid portion, and various modifications other than the embodiment can be made. Further, according to the present invention, since the lid portion and the lower lid portion are connected to each other by the connecting portion and are in a complementary relationship with each other, the lid portion is more closely contacted with the receiving portion and the repulsion and separation force is stronger than the conventional one. To do. For this reason, the inconvenience that the lid part naturally opens during use and the opened lid part is closed by a small external force is eliminated.
