Description

  The present invention relates to a container with a cap using magnetic force.

  As an engagement structure between the container and the cap, it has been known to use a magnetic force to prevent the cap from being accidentally detached or to easily attach and detach the cap with a lighter force.

  For example, in Patent Literature 1, magnets are arranged so that different magnetic poles are opposed to each other around the entire contact portion between the cap and the container body when the lid is completely covered, and the magnets are magnetically attached to each other. (Patent Document 1).

  However, in the configuration of Patent Literature 1, since the cap is engaged only by magnetic force due to magnetic force, the cap may be easily detached by an external force such as carrying, shaking, or dropping.

  Therefore, Patent Document 2 discloses a configuration in which a cap is hardly removed by providing a step in addition to the configuration by magnetic adhesion.

  Hereinafter, embodiments for implementing the present invention will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and duplicate description may be omitted.

  The present invention relates to a container with a cap using magnetic force. The container with a cap of the present invention includes, for example, cosmetics (basic cosmetics, base makeup cosmetics, point makeup cosmetics), cosmetics such as facial cleansers, hair styling, perfumes, and various liquids such as seasonings. The powder is stored. In addition, since sealing with a cap is possible, a substance (liquid or powder) containing a volatile component can be stored.

<First embodiment>
First, an outline of an engagement structure between the container body 1 and the cap 3 in the container 5 with a cap according to the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a top perspective view showing a state where the cap 3 and the container body 1 of the first embodiment of the present invention are separated. FIG. 2 is a bottom perspective view showing a state where the cap 3 and the container body 1 of the first embodiment are separated. FIG. 3 is a cross-sectional perspective view of the cap 3 and the mouth of the container body 1 according to the first embodiment.

  A container with a cap (a container with a lid) 5 according to the embodiment of the present invention includes a container body 1 and a cap (a lid) 3.

  The container main body 1 is a container capable of storing liquid or powder. The container body 1 is provided with a mouth 11 projecting upward from a shoulder 19. 1 to 3 show the mouth portion 11 and the shoulder portion 19, which are the upper side of the container main body 1, and the housing portion 10 as the trunk extends below the shoulder portion 19. (See FIG. 5). The mouth portion 11 has a cylindrical shape having an upper surface, and has an upper wall 12 and a peripheral wall 13 as a side surface.

  At the center of the upper wall 12 of the mouth 11, a hole 14 penetrating vertically is formed. Around the hole 14, an abutting projection 15 is formed, which is recessed in a mortar shape (funnel shape) toward the hole 14 and protrudes upward in an annular shape on the upper wall 12.

  A ring-shaped magnet support band 16 is provided on the inner peripheral side of the peripheral end of the upper wall 12. The magnet support band 16 is thicker than other parts of the upper wall 12. The magnet support band 16 has a plurality of magnet insertion holes 17 opened downward. An annular rib 18 is further provided on the lower surface of the upper wall 12.

  The cap 3 is detachably attached to the mouth 11 of the container body 1 so as to be able to be hermetically fitted. The outer surface of the cap 3 is constituted by a ceiling wall 31 and an outer wall 37. The cap 3 is provided with a hanging cylindrical wall 32 that hangs downward from the lower surface of the ceiling wall 31 in an annular shape. The cap 3 has a double side wall structure. The outer side is an outer side wall 37 and the inner side is a hanging cylindrical wall 32.

  In the cap 3, a projecting plug (also referred to as a boss, a sealing projection, or a sealing portion) 33 is provided at the center of the hanging cylindrical wall 32 so as to project downward from the lower surface of the ceiling wall 31. The plug 33 can be inserted into the hole 14 which is a fitting hole of the mouth 11. The plug portion 33 has a large diameter portion 331 located at the distal end portion and a shaft portion 332 which is a small diameter portion. The large diameter portion 331 has a larger diameter than the shaft portion 332 and is inserted into the hole portion 14. It becomes a large diameter part when it is done. Due to the shape of the plug portion 33, when the plug portion 33 is inserted into the hole portion 14, the plug portion 33 has a plugging structure, and the cap 3 hermetically seals the container body 1.

  As shown in FIGS. 1 and 3, a ring-shaped magnet support band 34 is provided on the inner peripheral side of the hanging cylindrical wall 32 of the cap 3. The magnet support band 34 is thicker than other portions of the ceiling wall 31. A plurality of magnet insertion holes 35 opening upward on the upper surface of the ceiling wall 31 are formed in the magnet support band 34. FIG. 3 shows a state in which the magnet is removed from the mouth 11 and the cap 3.

  In the ceiling wall 31, a lower surface sandwiched between the plug portion 33 and the magnet support band 34 is an abutting surface 36 that abuts against the abutting projection 15.

  FIG. 4 is a view showing the magnetic poles of the magnet provided on the cap 3 and the mouth 11 of the container body 1 of the present invention.

  In the engagement structure of the present invention, each of the mouth 11 and the cap 3 is provided with a magnet that generates a magnetic force between the mouth 11 and the cap 3.

  Specifically, as described above, an annular magnet support band 16 is provided on the inner periphery of the peripheral end of the upper wall 12 of the mouth 11 of the container body 1. An annular magnet support band 34 is provided on the inner peripheral side of the hanging cylindrical wall 32 of the cap 3 so as to face the magnet support band 16 of the mouth 11.

  The magnets of the mouth portion 11 and the cap 3 are formed on the annular magnet support bands 16 and 34 by a plurality of homopolar portions (21, 41) arranged at equal intervals in a circumferential shape and a plurality of homopolar portions. It is formed by a plurality of other pole portions (22, 42) provided therebetween.

  Specifically, as shown in FIG. 4, N-pole magnets 21 and S-pole magnets 22 are alternately arranged in the mouth portion 11, and N-pole magnets 41 and S-pole magnets 42 are alternately arranged in the cap 3. Then, in a state in which the cap 3 is closed with respect to the mouth portion 11, as shown in FIG.

  In the example shown in FIG. 4, the magnets are provided at every 45 degrees. Therefore, when the magnets are rotated by 45 degrees from the magnetized state, the magnets of the same polarity facing each other, that is, the N pole magnets 21 and 41 and the S pole A repulsive force acts between the magnets 22 and 42.

  As described above, it is necessary to dispose two types of magnets having different polarities for exerting an attractive force and the same polarity for exerting a repulsive force on the same surface. Therefore, at least two magnets are provided in each of the mouth portion 11 and the cap 3. .

  Further, in the rotation operation for releasing the close contact state, from the position where the different poles where the attractive force acts opposes, to the position where the same pole where the repulsive force acts opposes, so as to reduce the amount of rotation at that time, Preferably, more magnets are arranged. FIG. 4 shows an example in which eight magnets are arranged at every 45 degrees in the mouth portion 11 and the cap 3, but the number of magnets is not limited to eight. In addition, in order to make an attraction and a repulsion work alternately in each of the mouth 11 and the cap 3, the number of magnets on one surface is an even number so that magnets of different polarity are adjacent to each other.

  FIG. 5 is a top perspective view showing a state where the cap 3 and the container body 1 are closed in the container 5 with a cap according to the first embodiment.

  The container body 1 shown in FIGS. 1 to 3 has a shoulder portion 19 and a mouth portion 11 on the upper side of the container body 1, and a liquid is stored below the shoulder portion 19 as shown in FIG. The storage unit 10 is a bottomed square tubular body (bottle). In the present embodiment, since the outer shape of the shoulder portion 19 of the container body 1 and the outer shape of the ceiling wall 31 of the cap 3 are substantially equal, when the cap is closed, the side surface of the cap 3 and the side surface of the container body 1 They overlap on the same plane.

  Here, as shown in FIG. 5, in each of the cap 3 and the mouth 11 of the container body 1, the magnets are arranged in an annular shape at intervals of 45 degrees, so that the attractive force is exerted due to the outer shape. It is preferable that the state in which the repulsive force is working can be distinguished from the state in which the repulsive force is working. Therefore, it is preferable that the ceiling wall 31 of the cap 3 is not a perfect circle in a top view, but a shape that can be determined to be rotated by 45 degrees, for example, a rectangle including a rectangle, a square, a diamond, or an ellipse. In addition, in the square, the corner may be rounded.

  FIG. 5 shows an example in which the ceiling wall 31 connected to the outer wall 37 in the cap 3 is substantially rectangular in a top view. In this example, the outer shape of the container body 1 when viewed from above is also substantially rectangular, but the outer shape of the shoulder portion 19 of the container body 1 may have a shape or size different from the shape of the cap. Good. However, in order to make the position of the cap 3 with respect to the mouth 11 easy to understand when the cap 3 is closed, the shape of the center of the shoulder 19 in top view should be the same as the center of the ceiling wall 31 of the cap 3. It is suitable.

  FIG. 5 shows an example in which the housing portion 10 has a substantially rectangular parallelepiped shape. However, in the container body 1, the mouth portion 11 has a shape capable of engaging with the cap 3, and the housing portion 10 may have a bottom. Any shape may be used. For example, the bottom (lower surface) of the housing 10 may be gradually widened or narrowed with respect to the shoulder 19 (upper surface), or the side of the housing 10 may be twisted, or the center of the trunk may be bent. It may have various shapes such as bulging or concave.

  Next, a cross section and a function will be described with reference to FIGS. FIG. 6 is a vertical cross-sectional view of the cross section A of FIG. 5 of the cap 3 and the mouth 11 of the container body 1 of the first embodiment.

  As described above, the hole 14 is formed in the upper wall 12 of the mouth 11 of the container body 1, and the abutting projection 15, the annular rib 18, and the magnet support band 16 are provided.

  In addition, in the section of section A in FIG. 5 shown in FIG. 6, the hanging cylindrical wall 32 is a vertical section that is closest to the outermost square wall 37. The outside of the hanging cylindrical wall 32 and the inside of the outside wall 37 are integrated.

  On the inner peripheral side of the hanging cylindrical wall 32 of the cap 3, a stopper 33, a magnet support band 34, and an abutting surface 36 are provided.

  As shown in FIG. 6, the distal end of the plug portion 33 of the cap 3 is a large-diameter portion 331 having a larger diameter than the other portion, the shaft portion 332. The diameter of the inner wall 14I of the hole 14 of the mouth 11 is wider than the shaft 332 of the plug 33 and narrower than the large diameter 331.

  FIG. 6 shows an example in which the large-diameter portion 331 is provided at the tip (lower end) of the plug portion 33, but the large-diameter portion 331 extends from the upper end of the plug portion 33 to the thickness of the hole portion 14. It may be provided in an intermediate part other than the part. For example, in the diagram of FIG. 6, the shaft portion 332 may further extend below the large diameter portion 331. Alternatively, in the vertical direction of the plug portion 33, all the portions may be large-diameter portions 331 having a diameter larger than the inner wall 14I of the hole portion 14.

  The inner wall 14I of the hole 14 is made of a material that is elastically deformed. Therefore, at the time of insertion or withdrawal, the inner wall 14I is elastically deformed, so that the large-diameter portion 331, which is the tip of the plug 33, pushes through the hole 14.

  Although FIG. 6 shows an example in which the inner wall 14I of the mouth portion 11 is elastically deformed, the outer shape of the large diameter portion 331 of the plug portion 33 may be elastically deformed instead of the inner wall 14I. . Alternatively, both the inner wall 141 and the large diameter portion 331 may be elastically deformed.

  Therefore, the outer circumference of the large diameter portion 331 is larger in diameter than the inner wall 141 of the hole portion 14 in a state in which the large diameter portion 331 is not elastically deformed. Since the sealed state between the cap 3 and the mouth 11 is not released, the contents do not leak even if the cap 3 is tilted, turned upside down, or shaken. Moreover, since the hanging cylindrical wall 32 is engaged so as to surround the outer periphery of the peripheral wall 13 of the mouth portion 11, it is unlikely to shift in the lateral direction.

  The upper surface of the magnet support band 16 of the mouth 11 and the upper surface of the upper wall 12 are substantially flush with each other, and the lower surface side of the upper wall is formed thick.

  In the present embodiment, the magnets 21 and 22 of the mouth 11 are inserted from below into a plurality of magnet insertion holes 17 opened downward on the lower surface of the magnet support band 16. Therefore, as shown in FIG. 6, a resin film is formed on the magnet 22 (21) on the upper surface of the upper wall 12 in the magnet support band 16 of the mouth portion 11 of the container body 1, that is, Since the resin remains in the upper portion without communicating vertically in the magnet insertion hole 17 of the magnet support band 16, the upper surface of the magnet 22 (21) is covered with the resin.

  The upper surface of the magnet support band 34 of the cap 3 is substantially flush with the upper surface of the ceiling wall 31, and is formed thicker on the lower surface side of the ceiling wall 31.

  In the present embodiment, the magnets 41 and 42 of the cap 3 are inserted from above into a plurality of magnet insertion holes 35 opened upward. Therefore, a resin film is formed under the magnet 41 (42). That is, the magnet insertion hole 35 of the magnet support band 34 does not communicate vertically and the resin remains at the lower part. On the lower surface of the magnet support band 34, the lower surface of the magnet 41 (42) is covered with resin.

  As described above, in the present embodiment, the magnets (22 (21) and 41 (42)) are covered by the resin in the portions that can be seen by the user in the state where the cap 3 is opened in both the mouth 11 and the cap 3. Therefore, the beauty of the mouth portion 11 and the back surface of the cap 3 during use can be maintained.

  In FIG. 6, the lower part of the magnet insertion hole 17 of the magnet support band 16 on the container body 1 side is open and the upper part of the magnet insertion hole 35 of the magnet support band 34 on the cap 3 side is open. After the insertion, it is more preferable to seal the magnet insertion holes 17 and 35 with a resin, a seal, or the like.

  Specifically, since the lower surface of the magnet support band 16 of the mouth portion 11 of the container body 1 is open, there is a possibility that the inserted magnets 21 and 22 and the liquid in the container may come into contact with each other. For this reason, the magnets 21 and 22 may be degraded by the liquid of the contents, or conversely, the components of the magnet, for example, alnico, ferrite, neodymium, samarium cobalt, etc. may flow out into the liquid, It is more preferable to cover the magnets 21 and 22 from below from the viewpoint of maintaining the quality of the liquid and safety.

  On the other hand, in the magnet support band 34 of the cap 3, after inserting the magnets 41 and 42 into the magnet insertion holes 35 whose upper surfaces are opened, the magnets are sealed with resin, so that the magnets are hidden from the user on the front and back surfaces of the cap 3. From the viewpoint of enhancing aesthetic appearance, it is more preferable to cover the magnets 41 and 42 with resin, a seal, or the like from above.

  The annular rib 18 stands on the lower surface of the upper wall 12 of the mouth portion 11, outside the hole portion 14, and on the inner peripheral side of the magnet support band 16, downward. The annular rib 18 projects below the magnet support band 16.

  Therefore, for example, when a strong force is likely to be applied to the lower surface of the shoulder portion 19 or the lower surface of the upper wall 12 from the liquid contained therein by shaking, dropping, or falling down the container 5 with a cap, On the inner peripheral side of the peripheral wall 13 of the portion 11, first, a force is applied to the annular rib 18. For this reason, the force from the liquid applied to the hole 14 and the magnet support band 16 is reduced. For example, even when a strong force is applied in the upward direction, unless the cap 3 is rotated, the opposed force is applied as a magnetic force. Since the attractive force acts between the magnets having different polarities, the fitted state of the plug portion 33 and the hole portion 14 is not released, and the plug portion 33 does not come off. Further, since the force on the magnet support band 16 is also weakened, the magnet is not broken. It is preferable that the annular rib 18 be formed of an elastic member in consideration of the application of a force.

  In the example shown in FIG. 6, the portion other than the magnet 21 of the cap 3, the portion other than the magnet 42 of the magnet support band 16 of the container body 1, the peripheral wall 13 of the mouth 11, the shoulder 19, and the housing portion 10 are made of resin. Although the example shown is shown, it may be composed of another material. For example, these portions may be made of tempered glass or the like.

  FIG. 7 is an explanatory view showing a state of fitting of the plug 33 in the cap 3 and the mouth 11 according to the first embodiment of the present invention. In FIG. 7, (a) is a state before the cap 3 and the container body 1 are in contact with each other, (b) is a state in which the hanging cylindrical wall 32 of the cap 3 has started to contact the peripheral wall 13 of the mouth 11, and (c) is a state. The large diameter part 331 of the plug part 33 of the cap 3 pushes the inner wall 141 of the hole part 14 and enters, and (d) shows a state in which the cap 3 and the mouth part 11 are tightly fitted.

  When the cap 3 is engaged with the container body 1, first, the outer shape of the ceiling wall 31 of the cap 3 and the outer shape of the shoulder portion 19 of the container body 1 are approached so as to overlap (FIG. 7A → FIG. 7). (B)). At this time, in the present configuration, the ceiling wall 31 of the cap 3 is rectangular and the shoulder 19 of the container body 1 is also rectangular and substantially the same size in a top view, and the ceiling wall 31 and the shoulder Since the centers of the caps 19 are substantially equal in the top view, the position of the cap 3 with respect to the mouth 11 can be set almost correctly without checking the back surface of the cap 3.

  7A to 7D, the orientation of the cap 3 using the outer shape of the cap 3 and the shoulder 19 in FIG. After correctly setting the cap 3, it is not necessary to rotate the cap 3 with respect to the container body 1.

  Then, as the first contact, the hanging cylindrical wall 32 of the cap 3 starts to contact the peripheral wall 13 of the mouth 11 (FIG. 7B). When the inner peripheral surface 32I of the hanging cylindrical wall 32 and the outer peripheral surface 130 of the peripheral wall 13 start to contact, the trajectory when the cap 3 approaches is roughly determined.

  In this state, the magnetic force acts so that the magnet 41 of the cap 3 is attracted to the magnet 22 of the fixed mouth portion 11 of the container body 1, thereby promoting the approach movement of the cap 3 to the mouth portion 11. When the cap 3 further approaches the container body 1, the plug 33 of the cap 3 enters the hole 14 of the mouth 11 (FIG. 7 (b) → FIG. 7 (c)). At this time, the abutting projection 15 is concaved in a mortar shape (funnel shape) toward the hole portion 14 and protrudes from the upper surface of the upper wall 12 of the mouth portion 11A and is formed in a funnel shape. Even when 3 is inclined, the plug 33 slides along the inclined portion above the abutting projection 15, and the plug 33 is guided to the hole 14.

  In the present example, an example in which the periphery of the hole 14 protrudes from the upper surface of the upper wall 12 of the mouth 11 as the abutting projection 15 has been described. Inside the thickness of the upper wall 12, a funnel-shaped concave portion is formed from the upper surface to the lower portion, and the hole penetrates below the concave portion, and has no protrusion. You may. Also in this shape, the plug 33 can be guided to the hole 14 which is the lower hole by the inclination of the funnel-shaped concave portion (upper hole).

  In the state shown in FIG. 7C, the large diameter portion 331, which is the tip end portion and has a large diameter, advances by pushing down the inner wall of the hole portion 14 in the state of FIG. 14I is elastically deformed so as to be crushed to the outer peripheral side.

  Thereafter, when the cap 3 is further approached to the mouth portion 11, a sealing fit state is established (FIG. 7C ⇒ FIG. 7D). When the cap 3 is engaged, the large diameter portion 331 at the tip of the plug portion 33 in the state of FIG. 7C is inserted over the narrow inner wall 141 of the hole portion 14 of the mouth portion 11 and then inserted into the plug portion 33. The airtightness is achieved in the state shown in FIG. 7D by bringing the shaft portion 332 into close contact with the inner wall 14I. In FIG. 7D, as shown in FIG. 4, magnets having different polarities are magnetically attached to the cap 3 and the mouth 11.

  When the cap 3 and the container body 1 are brought closer to the position shown in FIG. 7B, an attractive force of the magnet acts. Therefore, by the action of this magnetic force, FIG. 7B → FIG. 7C → FIG. ) Is assisted. Accordingly, in the transition from the state of FIG. 7B to the state of FIG. 7C to the state of FIG. 7D, the force of the user to make the sealed state is greatly reduced, and the mounting of the cap 3 is completed. it can.

  Conversely, when the cap 3 is detached, the action of the attractive force applied in the direction of bringing the cap 3 into close contact with the mouth 11 is released, and the repulsive force applied in the direction of separating the cap 3 from the mouth 11 is exerted. Then, the cap 3 is rotated with respect to the container body 1.

  FIG. 8 is a top perspective view showing a state where the cap 3 according to the first embodiment of the present invention is rotated with respect to the mouth portion 11. FIG. 9 is an exploded cross-sectional view of the state of FIG.

  As shown in FIGS. 8 and 9, by rotating the cap 3 by 45 degrees from the closed state, the same poles of the magnets 41 and 42 of the cap 3 and the magnets 21 and 22 of the mouth 11 face each other.

  Thus, a repulsive force acts between the magnet of the mouth portion 11 and the magnet of the cap 3, and the repulsive force cancels the airtight state by the shaft portion 332 of the plug portion 33 and the inner wall 14 </ b> I of the hole portion 14. The force for the 331 to climb over the hole 14 can be greatly reduced.

<Modification of plug section>
In the above example, the plug portion 33 has a configuration including the large diameter portion 331 and the shaft portion 332, but the plug portion 33 may have a different shape.

  FIG. 10 is a side sectional view of the cap 3α having the plug 33α of the first modification and the mouth 11 of the container body 1. As shown in FIG. 10, in the cap-equipped container 5α of the present modification, the stopper 33α is configured by a column 333.

  Also in this modification, at least one of the plug portion 33α and the inner wall 141 of the hole portion 14 is made of a material that is elastically deformed. Therefore, when fitting, the cylinder 333 having a uniform thickness enters in a state of being in close contact with the inner wall 14I and stops in a state of being in close contact, so that airtightness in the fitted state is achieved.

  In FIG. 10, an example in which the plug portion 33α is formed by the column 333 having a uniform thickness is shown, but the plug portion 33α contacts the inner wall 14I of the hole portion 14 in the fitted state, for example, in the cylindrical plug portion. One or more portions (flange portion, ring portion) having a slightly larger diameter may be provided in the portion. By providing the flange portion, the other outer peripheral portion of the columnar portion does not come into close contact with the inner wall 14I of the hole portion 14, but comes into close contact only with the flange portion. Thereby, at the time of plugging of the plug into the hole 14, the response to the contact with the inner wall 14I at the flange portion changes, and the fitted state can be easily understood.

  FIG. 11 is a side cross-sectional view of the cap 3β having the plug 33β of the second modification and the mouth of the container body 1. As shown in FIG. 11, in the cap-equipped container 5β of the present modification, the stopper 33β is configured by a downward cone 334.

  The diameter of the plug 33β, which is the downward cone 334, gradually increases from the lower end toward the top. Therefore, in the fitting operation, the lower portion having a small diameter enters the inside of the hole portion 14 without making much contact with the inner wall 14I of the hole portion 14, and when the penetration of the plug portion 33β reaches an appropriate fitting height, the lower portion is turned downward. The thickened portion of the cone 334 and the inner wall 14I of the hole 14 come into contact with each other to be in a fitted state.

  In this modification, at least one of a portion (at least a part) of the plug portion 33β that comes into contact with the inner wall 141I of the hole 14 in the fitted state and at least one of the inner wall 141 of the hole is made of an elastically deformable material. Be composed. Therefore, at the time of fitting, the downward cone 334 and the inner wall 141 come into contact with each other to stop the approach, so that airtightness in the fitted state is achieved.

  Although FIG. 11 shows an example of a downward conical shape, the leading end (lower end) may have a flat downward truncated conical shape or a lower conical shape with a rounded lower end.

FIG. 13 is a bottom perspective view showing a state where the cap 3A and the container body 1A of the second embodiment are separated. FIG. 14 is a cross-sectional perspective view of the cap 3A and the mouth 11A of the container body 1 according to the second embodiment.

  In the present embodiment, the arrangement position of the magnet in the magnet support band is different from that of the first embodiment. In the first embodiment, a plurality of magnet insertion holes 17 opened downward are formed in the magnet support band 16 of the mouth portion 11, and a plurality of magnet insertion holes opened upward are formed in the magnet support band 34 of the cap 3. A hole 35 was formed.

  On the other hand, in the present embodiment, a plurality of magnet insertion holes 17A that are open upward are formed in the magnet support band 16A of the mouth 11A on the container body 1 side, and are formed in the magnet support band 34A of the cap 3A. Has a plurality of magnet insertion holes 35A opened downward.

  Therefore, as shown in FIG. 12, the upper surfaces of the magnets 23 and 24 are exposed from the opening of the magnet insertion hole 17A on the upper surface of the upper wall 12A in the magnet support band 16A of the mouth 11A of the container body 1A. Then, as shown in FIG. 13, in the magnet support band 34A of the cap 3A, the lower surfaces of the magnets 43 and 44 are exposed on the lower surface (back surface) from the opening of the magnet insertion hole 35A.

  FIG. 15 is a top perspective view of the entire container with the cap 3A closed in the container 5A with a cap according to the second embodiment. FIG. 16 is a side sectional view of the cap 3A and the mouth 11A of the container body 1A according to the second embodiment.

  In the present embodiment, as shown in FIGS. 13 and 14, magnets 23, 24, 43, and 44 are provided on the upper surface of upper wall 12A of mouth 11A of container body 1A and the lower surface of magnet support band 34A of cap 3A. Is exposed, the magnets (24, 43) and (23, 44) come into direct contact with each other as shown in FIG. Therefore, it is possible to exert a greater magnetic force than in the first embodiment. Therefore, the size of the magnets (23, 24, 43, 44) can be reduced as compared with the magnets 21, 22, 41, 42 provided in the configuration of FIG.

  In the present embodiment, the magnets 23 and 24 at the mouth 11A are exposed on the upper surface side of the upper wall 12A and the lower surface of the magnet support band 16A is covered with resin. In addition, a cover from the lower surface for sealing the openings of the magnets 23 and 24 becomes unnecessary.

  Further, in the present embodiment, since the magnets 43 and 44 are exposed on the lower surface side of the magnet support band 34A in the cap 3A and the upper surface of the ceiling wall 31A is covered with resin, the cap 3A is closed as shown in FIG. When it is, the magnet is not visible from the external appearance of the cap 3A. Therefore, a cover from the upper surface for sealing the openings of the magnets 43 and 44 to improve the appearance when the cap is closed is not required.

  In the present embodiment as well, the shape of the plug portion 33 provided on the cap 3A may be a shape as in the modified example shown in FIGS.

  Drawing 17 is an explanatory view showing signs of fitting in each state of cap 3A and container body 1A of a 2nd embodiment. In FIG. 17, (a) shows the state before the cap 3A and the mouth 11A come into contact with each other, (b) shows the state in which the hanging cylindrical wall 32 of the cap 3A has started to contact the peripheral wall 13 of the mouth 11, and (c) shows the cap. In the state where the large diameter portion 331 of the plug portion 33 of 3A pushes and spreads the inner wall 141 of the hole portion 14 of the mouth portion 11A, (d) shows that the cap 3A and the mouth portion 11A are tightly fitted. Indicates the status.

  When the cap 3A is engaged with the container main body 1A, first, the outer shape of the ceiling wall 31A of the cap 3A and the outer shape of the shoulder portion 19 of the container main body 1A are brought closer so as to match (FIG. 17 (a) → FIG. 17). (B)). Thus, the inner peripheral surface 32I of the hanging cylindrical wall 32 of the cap 3A starts to contact the outer peripheral surface 130 of the peripheral wall 13 of the mouth 11A (FIG. 17B). At this time, the magnetic force acts so that the magnet 43 of the cap 3A is attracted to the magnet 24 of the mouth 11A of the fixed container body 1A, thereby promoting the approach movement of the cap 3A to the mouth 11A.

  When the cap 3A further approaches the container body 1A, the plug 33 of the cap 3A enters the hole 14 of the mouth 11A. The stopper 33 is guided to the hole 14 by the funnel-shaped abutting projection 15. In the state shown in FIG. 17C, the inner wall 14I of the hole 14 is elastically deformed by the large-diameter portion 331 of the plug 33 so as to be crushed to the outer peripheral side.

  Thereafter, when the cap 3A further approaches the mouth portion 11A, the cap 3A is in a sealed fitting state (FIG. 17C → FIG. 17D). When the cap 3A is engaged, the large-diameter portion 331 at the tip of the plug portion 33 in the state of FIG. 17C is inserted over the narrow inner wall 141 of the hole portion 14 of the mouth portion 11A, and is thus inserted. In the state of (d), the shaft 332 of the plug 33 is brought into close contact with the inner wall 14I by tapping, whereby airtightness is achieved.

  Also in this embodiment, when the magnet is brought close to the position shown in FIG. 17B, the closing action shown in FIG. 17B → FIG. 17C → FIG. 17D is assisted by the action of the magnetic force. . Therefore, FIG. 17 (b) → FIG. 17 (c)) → FIG. 17 (d) shows that the user's force for sealing is greatly reduced, and the cap 3A is not rotated without rotating the cap 3A. Can be completed.

  Conversely, when detaching the cap 3A, the cap 3A is rotated in order to release the action of the attractive force by the magnet and to exert a repulsive force.

  FIG. 16 is an exploded cross-sectional view illustrating a state where the cap 3A according to the second embodiment of the present invention is rotated with respect to the mouth 11A.

  As shown in FIG. 16, by rotating the cap 3A by 45 degrees from the closed state, the same poles of the magnets 43 and 44 of the cap 3A and the magnets 23 and 24 of the mouth 11A face each other.

  As a result, a repulsive force acts between the magnets 23 and 23 of the mouth 11A and the magnets 43 and 44 of the cap 3A, and the airtight state by the shaft 332 of the plug 33 and the inner wall 14I of the hole 14 is released. The force for the large diameter portion 331 to climb over the hole portion 14 can be greatly reduced.
