In the pot type water purifier, the surface having the spout 43 is defined as the front surface, the surface having the handle 61 is defined as the back surface, and the stopper 13 side is defined as the top surface.

  The water purifying water storage part 14 which comprises the lower part of the main body container 11 is a substantially rectangular parallelepiped liquid storage container having a bottom and a side, and has a handle 61 on the back surface. When the pot type water purifier is tilted sideways, the pot is grounded. A pedestal 62 for assisting the stable placement of the water purifier is provided on the upper right side. Plastic containers are weaker and easier to break than containers made of other materials such as iron or wood, and if there are corners, there is a risk of stress concentrating and breaking easily. In order to increase rigidity, the side surface is often formed with a curved surface. Therefore, the pot-type water purifier is also easy to roll when it is placed on its side, and it is easy to roll and unstable storage. If the pedestal 62 is grounded as in the present embodiment, the pot-type water purifier can be stably stored even when it is placed on its side. A plurality of pedestals 62 may be provided, but the pot-type water purifier can be placed stably if at least three locations of the water purifying water storage unit 14, the handle 61, and the pedestal 62 are grounded. The pedestal is preferably located at one upper position.

  A cover fixing groove 94 for guiding the cover fixing protrusion 84 of the cover 73 to the cover fixing hole 99 is provided on the upper surface. The depth was about 1 [mm], and the width was such that the cover fixing hole 99 side was narrow and the back side was wide. The cover fixing hole 99 has a diameter of about 1 [cm] and a depth of about 3 [mm] on the locking portion 72, and has a shape for fixing the cover fixing projection 84 of the cover 73.

  A method for attaching the cover 73 to the grip portion 71 and the connecting portion 72 will be described. A cover fixing hole 83 on the lower surface of the cover 73 is hooked on the cover fixing protrusion 93 on the lower surface of the grip portion 71, and the cover fixing protrusion 84 on the back surface of the cover 73 is placed on the back side of the cover fixing groove 94 on the upper surface of the grip portion 71. The upper side of the cover 73 is pushed from the back side, and the cover fixing projection 84 is moved along the cover fixing groove 94 and fitted into the cover fixing hole 99 at the tip of the cover fixing groove 94. Since the width of the cover fixing groove 94 on the upper surface of the grip portion 71 is increased toward the back side, the cover fixing groove 84 is inserted into the cover fixing groove 94 even though the cover fixing protrusion 84 is arranged on the back side of the upper surface of the cover 73. It is easy to do and the cover 73 can be installed smoothly.

  The slider 74 is used by being mounted between the use start time display surface 91 of the grip portion 71 and the column 98. The shape was close to that of H steel and was formed of ABS resin. The dent is directed to the front side and the back side, and is used at a position where the plane is the right side and the left side. The recess on the front side is recessed in a U-shape, the recess on the back side is recessed in a semicircular shape, and the recess on the back side is fitted into the columnar shape of the column 98 of the grip portion 71. The slider 74 uses a partially expanded space provided at the upper end of the space provided in the gripping portion 71, applies a semicircular recess of the slider 74 to the semi-cylindrical portion of the column 98, and uses the column 98 as a fulcrum to support the right side surface of the slider 74. Rotate while pressing and insert.

  A positioning projection 101 that meshes with the slider positioning recess 95 of the grip portion 71 and fixes the position of the slider 74 is provided below the right side surface inside the U-shaped portion. The positioning projection 101 may be on the left side inside the U-shaped part, or may be provided on both the left and right sides inside the U-shaped part. However, since the user moves the slider 74, only the back of one side is engaged. Is preferable because it can be moved with a small force. The slider 74 is fitted by sliding it down after being fitted into the upper end of the space. The positioning protrusion 101 may be at the center or upper side inside the U-shaped part, but if it is at the lower side, the moving distance until it fits into the nearest slider positioning recess 95 is small, and the inserted slider 74 can be fixed immediately. preferable.

  The positioning projections 101 of the slider 74 and the projections and depressions of the slider positioning recess 95 of the gripper 71 may be engaged so that the position of the slider 74 can be fixed, and the positioning recess may be provided on the slider 74 and the slider positioning projection may be provided on the gripper 71.

  Although formed with an ABS resin that has good molding accuracy and is difficult to scrape even when the slider 74 is repeatedly moved, other resin molded products such as polypropylene may be used.

  On the right side of the outer side of the U-shaped portion of the slider 74, a use start arrow 102 is provided by resin irregularities. When exchanging the cartridge, the cover 73 is removed, the slider 74 is moved, and the use start arrow 102 is set to the corresponding number on the use start time calendar 96 on the grip 71. When the cover 73 is attached, the slider 74 can be seen from the window hole 81 of the cover 73 through the window 92 of the grip portion 71 as shown in FIG. With respect to the replacement time calendar 85 arranged on the right side of the window hole 81, the upper end of the slider 74 represents the cartridge use start time, and the lower end represents the cartridge replacement time.

  Since the slider 74 cannot be touched unless the cover 73 is removed, it is possible to prevent the user from moving the slider 74 by mistake when the user normally uses the pot type water purifier. In addition, since the range from the use start time of the cartridge to the replacement time is shown in the replacement time calendar 85, it is possible to inform the user how much the cartridge has been used for the life of the cartridge today. It is possible to give more information to the user than to display only the replacement time.

  The slider 74 is preferably a colored member that can be easily seen through the window 92 in order to clearly convey the effective period of the cartridge.

  The inner container receiving portion 15 will be described with reference to FIG. FIG. 16 is a longitudinal sectional view as seen from the right side of the inner container.

  The inner container receiving portion 15 constituting the upper part of the main body container 11 is provided with a female screw 41 that can be fastened to the outer peripheral screw 33 of the inner container 12 on the inner wall and a large packing attached to the outer periphery of the inner container 12 below the female screw 41. It was made into the shape which has the sealing surface 42 which presses 34, and the spout 43 which pours purified water into the upper end, and formed with polystyrene. Moreover, the welding groove | channel 44 for performing ultrasonic welding with the purified water storage part 14 was provided in the lower end over the perimeter.

  Since the purified water storage part 14 and the inner container receiving part 15 use the same raw material, the adhesiveness of ultrasonic welding is good. Since there are many members and screw structures such as the inner container receiving part 15 and the inner container 12 and the inner container 12 and the stopper 13 around the inner container receiving part 15, the state of being cluttered with the transparent raw material can be seen through. The portion 15 is preferably an opaque colored member.

  The colored raw material is melted by providing a welding convexity in the purified water reservoir 14 using the transparent raw material and a welding groove in the inner container receiving portion 15 using the colored raw material, and melting the transparent raw material during ultrasonic welding. Appearance defects due to erosion of the transparent member can be avoided.

  Purified water is poured from the gap between the sealing surface 42 of the inner container receiving portion 15 and the large packing 34 of the inner container 12. It flows through the inner wall surface where the clean water female screw 41 is formed. The female screw 41 may be on the inner wall of the inner container receiving portion 15 more than once, but since the screw thread near the spout 43 is deleted, the purified water passes through this portion and the shape of the purified water flowing out is easy to pour. Further, since the screw thread near the handle 61 is also deleted, there is an effect that the core portion of the molding die can be made by a slide instead of a screw.

  The purified water storage part 14 and the inner container receiving part 15 may be resin molded products such as polypropylene, polycarbonate, acrylic resin, polyethylene, ABS resin (acrylonitrile butadiene styrene resin), and are connected and bonded by fitting with sealing performance. You may fix by the adhesion | attachment by an agent. However, for pot-type water purifiers that may be stored sideways, there is concern about water leakage when mated, and there is concern about elution into purified water when bonding with adhesives. Bonding by sonic welding is preferable because water leakage can be reliably prevented and elution by an adhesive can be reliably prevented.

  The internal container receiving part 15 is arranged on the purified water storage part 14. The purified water storage part 14 is easily stored in the door pocket of the refrigerator by being formed in a substantially rectangular parallelepiped shape that spreads upward from the bottom surface having a long side of about 11 [cm] and a short side of about 8 [cm] at a draft of 2 °. About 1.5 [cm] above, the opening was suddenly widened from a substantially rectangular parallelepiped, and the shape was a curved surface connected to the inner container receiving portion 15. In this case, the lower part of the substantially rectangular parallelepiped excluding the curved surface connected to the inner container receiving part 15 above the purified water storage part 14 is referred to as a substantially rectangular parallelepiped part. The inner container receiving portion 15 was formed in a substantially cylindrical shape having a maximum diameter of about 15 [cm] while the upper end of the substantially rectangular parallelepiped portion had a long side of about 12 [cm] and a short side of about 10 [cm]. The inner container receiving portion 15 is formed larger than the outer shape of the substantially rectangular parallelepiped upper end without being limited by the dimension of the short side 10 [cm] at the upper end of the substantially rectangular parallelepiped portion of the purified water storage portion 14, so that the inner container mounted inside the inner container receiving portion 15. A maximum of about 10.5 [cm] was also secured for the inner diameter of 12. Since the maximum inner diameter is 10 [cm] or more, the user can easily put his hand inside the inner container 12 and can easily remove the cartridge 2. Moreover, since the capacity | capacitance which puts raw | natural water could be enlarged, the amount of purified water obtained by one filtration could be increased. By making the maximum diameter of the inner container receiving part 15 larger than the short side above the purified water storage part 14, it is easy to store in the door pocket of the refrigerator and two contradictory advantages that a large amount of purified water can be obtained at one time. Realized a pot-type water purifier with

  At this time, when the pot-type water purifier is placed on its side, the outer periphery of the water-purifying water storage unit 14 and the inner container receiving unit 15 are grounded, so the pot-type water purifier is easy to roll and becomes unstable storage. Since the handle 61 is grounded, there is an advantage that the pot-type water purifier can be prevented from rolling, and can be stably tilted and stored.

  The structure and usage of the inner container 12 and the stopper 13 will be described with reference to FIGS. 17 is a cross-sectional view of the inner container according to one embodiment of the present invention as viewed from the right side, FIG. 18 is a top view of the inner container according to one embodiment of the present invention, and FIG. 19 is according to one embodiment of the present invention. Sectional drawing seen from the right side of the stopper is shown, respectively.

  The inner container 12 was formed in a high-impact polystyrene having a bowl-like shape having an opening for the cartridge connection portion 32 on the bottom surface and a water supply port 31 for feeding raw water upward. Three cartridge fixing protrusions 105 are arranged at equal intervals on the inner wall of the cartridge connection portion 32. When repeatedly performing the operation of placing the pot type water purifier upright or tilting it sideways, the force of the moment is applied to the cartridge connection part 32 due to the weight of the cartridge 2 and the cartridge connection part 32 may come loose. is there. Three cartridge fixing protrusions 105 having a thickness of 0.9 [mm] are provided on the inner wall of the cartridge connecting portion 32 with respect to a gap of 0.6 [mm] with the cartridge 2. By strengthening the fitting with the cartridge 2, there is no room for the cartridge 2 to tilt, and it is possible to prevent the cartridge 2 from loosening. On the outer peripheral surface, an outer peripheral screw 33 is provided above, and a large packing groove 106 is provided below the outer peripheral screw 33, and a large packing 34 is attached. On the inner peripheral surface, an inner peripheral screw 35 is provided above, and a seal surface 36 is provided on the inner peripheral screw 35. A part of the upper end is formed as a surface 37 that covers the spout. The surface 37 covering the spout is provided with a notch 38 at a position near the tip of the spout 43, and a locking projection 39 having a height of about 3 [mm] is provided at substantially the center of the surface 37 covering the spout. It was.

  The outer peripheral screw 33 was formed as a square screw and was fastened to the female screw of the inner container receiving portion 15. The clean water is poured by loosening the space between the outer peripheral screw 33 of the inner container 12 and the female screw 41 of the inner container receiving portion 15. Because of the square screw, the inner container 12 can be moved upward with less rotation than the first screw, and a flow path for pouring purified water can be secured, making it easy to pour. After the water injection, the outer peripheral screw 33 is screwed in, and the large packing 34 is pressed against the sealing surface 42 of the inner wall of the inner container receiving portion 15 to compress it, thereby sealing the purified water accumulated in the purified water storage portion 14 from leaking out.

  The stopper 13 has a shape including a side surface having a thread on the outer periphery and a top surface, and is used by being screwed into an inner peripheral screw 35 of the inner container 12. A male screw 51 is provided on the outer periphery of the side surface with a first power screw, and a small packing 52 is attached to a small packing groove 58 on the male screw 51 for use. The male screw 51 is screwed into the inner peripheral screw 35 of the inner container 12, and the small packing 52 is pressed against the sealing surface 36 of the inner container 12 and compressed to seal the raw water remaining in the inner container 12 from leaking out. A circumferential rib 57 having a height of about 2 [mm] was provided on the back side of the top surface of the stopper 13. When a cartridge 200 different from the present embodiment is used, the side surface of the other cartridge 200 does not contact the cartridge fixing protrusion 105 provided on the inner wall of the cartridge connecting portion 32 of the inner container 12, and the cartridge fixing protrusion 105 is effective. Absent. By supporting another cartridge 200 with a circumferential rib 57 provided on the back side of the top surface of the stopper 13, it is possible to prevent looseness from the cartridge connection portion 32 due to the inclination of the other cartridge 200.

  A handle 53 having a length substantially the same as the outer diameter of the top surface is provided on the top surface. Since the stopper 13 can be turned by grasping the handle 53, the male screw 51 can be easily screwed. In addition, when storing on a refrigerator shelf, if the handle 53 is on the front and the water purifier 14 is stored on the shelf, the pot-type water purifier can be easily removed using the handle 53 on the front. be able to. Furthermore, even when a pot-type water purifier is stood and stored in a drawer at a low position in a refrigerator such as a vegetable room, it can be easily taken out by holding the handle 53 and pulling up the pot-type water purifier. .

  Above the handle 53 is a cantilever lever 54. The tip located on the spout 43 with all screws closed can be displaced up and down.

  Here, the usefulness of the lever 54 in this Embodiment is demonstrated using FIGS. 20 is a right side view of an assembled state of an inner container and a stopper according to an embodiment of the present invention, FIG. 21 is a front view of the state of FIG. 20, and FIG. 22 is an assembled product according to an embodiment of the present invention. FIG. 23 is a top view showing the positions of the inner container and the cover when the stopper is rotated 180 degrees according to an embodiment of the present invention.

  In this embodiment, the main body container 11 and the inner container 12, and the inner container 12 and the stopper 13 are sealed by screwing, respectively, to prevent water leakage of purified water and raw water. In this case, if the screw between the main body container 11 and the inner container 12 is loosened, the purified water stored in the purified water storage part 14 can be poured, and the screw between the inner container 12 and the stopper 13 does not need to be loosened. However, the inner container 12 does not have a grip portion, and the operation of rotating the inner container 12 while holding the side surface of the inner container 12 is very inconvenient. Further, if a portion that can be gripped by the inner container 12 is provided, the handle cannot be attached to the stopper 13, and the handle of the stopper 13 and the portion that the inner container 12 can be gripped interfere with each other. Further, when raw water is filtered through the water supply port 31 above the inner container 12, not only the plug 13 is removed from the inner container 12 but also the screw between the main body container 11 and the inner container 12 is loosened to loosen the inside of the main body container. Without securing the air outlet, the air in the main body container cannot be discharged without tightening the screw, so that the raw water cannot flow into the cartridge 2. Every time raw water is supplied and filtered, the two screws must be opened, which is also not easy to use.

  Therefore, by turning the stopper 13 by 10 to 180 ° from the state where all the screws are tightened, the screw between the main body container 11 and the inner container 12 can be loosened and the purified water can be poured. As a structure in which the screw between the inner container 12 and the stopper 13 can be loosened by rotating 180 ° or more to supply the raw water, a lever 54 is attached to the handle 53 of the stopper 13, and the hook protrusion 55 and the hook protrusion 55 are provided on the back side of the lever 54. Further, two protrusions, a semicircular climbing protrusion 56 having a thickness of about 2 [mm] and a height of about 3 [mm], which are located further outside are provided.

  First, the stopper 13 is opened by turning about 5 °. The hooking protrusion 55 comes into contact with the locking protrusion 39 provided on the surface 37 that covers the spout of the inner container 12. When the stopper 13 is further rotated and opened in the state as it is, the stopper 13 is rotated and opened while the hooking protrusion 55 is hooked on the stopper protrusion 39, so that the inner container 12 is interlocked with the stopper 13 and starts rotating together. In the present embodiment, the hooking protrusion 55 and the locking protrusion 39 correspond to the locking means. In the range in which the stopper 13 is turned by 10 to 180 °, the sealing of the large packing 34 of the inner container 12 and the sealing surface 42 of the inner container receiving portion 15 is released, and the purified water can be poured. When the stopper 13 is rotated by about 180 °, the overhanging protrusion 56 comes into contact with the upper end of the cover 73 of the handle 61. If the stopper 13 is further rotated and opened as it is, the climbing projection 56 rides over the upper end of the cover 73, so that the lever 54 is elastically deformed upward by about 3 [mm]. At this time, the notch 38 of the inner container 12 hits the inner container fixing wall 82 of the cover 73, and the inner container 12 stops at a position rotated by 180 °. In the present embodiment, the inner container fixing wall 82 corresponds to the stopping means. When the stopper 13 is further rotated and opened, the climbing projection 56 climbs over the upper end of the cover 73 while the inner container 12 is stopped, and the latching state of the latching projection 39 and the hooking projection 55 is released as shown in FIG. In the present embodiment, the cover 73 corresponds to the release means. If the stopper 13 is further rotated and opened in this state, the stopper 13 can be removed. When the stopper 13 is removed, the sealing of the packing size 34 of the inner container 12 and the sealing surface 42 of the inner container receiving part 15 is released, and when the raw water is put into the water supply port 31 above the inner container 12, the raw water is not dead. It passes through the cartridge 2 and is filtered. When the filtration is completed and the stopper 13 is attached and turned in the closing direction, the hooking protrusion 55 hits the engaging protrusion 39, the stopper 13 and the inner container 12 start rotating together, and when further turned, the inner container 12 and the inner container receiving part 15 The screw between the stopper 13 and the inner container 12 begins to fasten. When the screw is fastened, first, the large packing 34 of the inner container 12 and the sealing surface 42 of the inner container receiving portion 15 are in a sealed state, then the hooking protrusion 55 gets over the locking protrusion 39, and finally, the plug 13 The space between the small packing 52 and the sealing surface 36 of the inner container 12 is sealed. Since the left side of the locking projection 39 is inclined, the hooking projection 55 can easily get over the locking projection 39 after the screw is fastened.

  In the present embodiment, the internal container 12 is hermetically sealed by screwing the male screw 51 of the stopper 13 into the inner peripheral screw 35 of the internal container 12 and compressing the small packing 52 on the sealing surface 36 of the internal container 12 in the vertical direction. The main body container 11 is hermetically sealed by screwing the sealing means and the outer peripheral screw 33 of the inner container 12 into the female thread 41 of the inner container receiving part 15 and compressing the large packing 34 onto the sealing surface 42 of the inner container receiving part 15 in the vertical direction. The main body container sealing means is composed of different sealing means. Therefore, even if the pot-type water purifier is placed sideways with the purified water or raw water before filtration, the purified water and raw water will not leak out, and the purified water and raw water will not be mixed. Since the pot-type water purifier can be stored in a horizontal position, the storage location and orientation can be freely selected, such as laying it on a shelf in the refrigerator when it does not fit in the refrigerator door pocket.

  In the present embodiment, the plug 13 is rotated and opened while the hook protrusion 55 of the stopper 13 is hooked on the locking protrusion 39 of the inner container 12, and the inner container 12 rotates together with the stopper 13. Therefore, by turning the stopper 13 by 10 to 180 °, only the screw between the main body container 11 and the inner container 12 can be loosened and the purified water can be poured.

  Further, when the stopper 13 is rotated and opened by about 180 °, the overpass projection 56 of the stopper comes into contact with the upper end of the cover 73 of the handle 61, the overturning protrusion 56 gets over the upper end of the cover 73, and the locking protrusion 39 and the hooking protrusion 55 are locked. Therefore, it is possible to supply the raw water by loosening the screw between the inner container 12 and the stopper 13 only by rotating the stopper 13 by 180 ° or more.

  Further, when releasing the locking state of the locking protrusion 39 and the hooking protrusion 55, the notch 38 of the inner container 12 hits the inner container fixing wall 82 of the cover 73, and the inner container 12 stops at a position rotated 180 °. Since the stop means is provided, the locked state can be reliably released.

  Since the main body container sealing means is formed with a double thread screw and the inner container sealing means is formed with a single thread screw, when the two screws are fastened with the stopper 13, the single container screw inner container sealing means is easier to tighten. Therefore, there is an effect that the main body container sealing means can be easily opened first when opening with the stopper 13. Further, since the double thread screw can move the inner container 12 upward with less rotation than the first power screw, there is an effect that it is easy to ensure a flow path for pouring purified water and to pour easily.

  Compared to the shape of a conventional cold water bottle that can be stored side-by-side by forming a part of the side with a flat surface without the handle, this embodiment is easy to carry and pour by first attaching the handle 61 Attached. In addition, when the holding portion 71 of the attached handle 61 is placed sideways in a plastic container such as a conventional cold water cylinder that is easy to roll and unstable when stored sideways, the purified water storage portion 14 The shape of the pot-type water purifier that touches down at the same time as the bottom. It has the effect of preventing rolling when placed sideways and allowing stable storage. In addition, regardless of the angle of the handle 61, the pouring spout 43 is always positioned vertically below the grip 71 when pouring clean water. There is an effect that the spout 43 is positioned at a position where the user can easily pour it without adjustment.

  Furthermore, by making the outer diameter of the inner container receiving part 15 larger than the short side of the upper end of the substantially rectangular parallelepiped part of the purified water storage part 14, the pot can be easily stored in the door pocket of the refrigerator and can obtain a large amount of purified water at once. Realized the special advantages of the water purifier. Even when the shape is such that it is easy to roll when placed sideways, it can be stably stored because the lower portion of the clean water storage section 14 and the gripping section 71 are in contact with each other at the same time.

  The shape of the pot-type water purifier that can be easily stored in the door pocket of the refrigerator and can obtain a large amount of purified water at one time is such that the handle 61 has a short side or a long side of the substantially rectangular parallelepiped part of the purified water storage part 14 as shown in FIG. By inclining by 20 to 25 ° with respect to the side, it is possible to form a shape in which the spout 43 is easy to pour and is positioned vertically below the grip portion 71.

  In the present embodiment, the cartridge replacement time display means is conventionally provided in the handle 61 that has been a dead space that can be grasped by the user. Since it is not necessary to prepare a space for cartridge replacement timing means, the pot type water purifier itself can be made compact. In addition, a slider 74 is movably mounted as a cartridge replacement time display member 202 that indicates the effective period of the cartridge so that the gripping portion 71 is sandwiched, so that the slider 74 can be moved relative to the effective period calendar 85 to change the time of the year. Even when the use of the cartridge is started, the replacement time of the cartridge can be expressed.

  Since the gripper 71 is provided with a slider positioning recess 95 as a positioning recess, and the positioning projection 101 is provided inside the slider 74, the slider 74 can be fixed at a fixed position during the use period of the cartridge. When the user accidentally touches the slider 74 while using the pot-type water purifier, the effective period of the cartridge is prevented from easily changing.

  By moving the slider 74 in the longitudinal direction of the grip portion 71, the space of the handle 61 can be used most effectively. Since the moving range of the slider 74 can be made large, the range in which the characters of the effective time calendar 85 can be displayed can be made large, and an easy-to-see display in which each character is large can be performed.

  A cover 73 is attached to the grip portion 71 to which the slider 74 is attached, and the slider 74 cannot be touched unless the cover 73 is removed. The effect which prevents that a user moves the slider 74 accidentally while using a pot type water purifier can be heightened further. Since the window 73 is provided in the cover 73 and the slider 74 is structured so as to be visible from the outside of the cover 73, the valid period of the cartridge can be confirmed with the cover 73 attached. Since it is not necessary to remove the cover 73 during use, the frequency with which the slider 74 is touched and moved by mistake can be reduced.

  A use start time calendar 96 is arranged on the grip portion 71. In the use start time calendar 96, the use start arrow 102 of the slider 74 is aligned with the number corresponding to the cartridge use start time, and the cover 73 is placed over the cover 73 so that the slider 74 indicates the effective period of the cartridge. Calendar 85 letters were arranged. The effective period of the cartridge can be displayed without considering the user.

  In addition, the form can be modified as follows.

  The cantilever lever 54 may be a single support at the end of the lever 54, but a lever support 200 may be added near the center of the lever 54 as shown in FIG. Preventing the lever 54 from being easily lifted and damaged by the small force that a hand catches or a child plays by shortening the distance between the climbing projection 56, which is an action point, and the support, which is a fulcrum, by increasing the support. it can.

  There is also a technique for preventing the damage by attaching a stopper 201 to the lever 54 so that the lever can be lifted only to a certain height. As the stopper, there are a shape in which the lever 54 and the handle 53 are sandwiched in the width direction as shown in FIG. 31, and a shape in which a pin is formed so as to penetrate the lever 54 and the handle 53 so as not to come off.

  Further, the lever 54 may be constituted by another member that is detachably attached to the handle 53. In this case, if the lever 54 is attached using a hinge structure so that the lever 54 is moved up and down as shown in FIG. 33, the lever 54 comes off when the lever 54 is lifted more than necessary, so that the damage is not generated. . In the vicinity of the center of the hinge, if the lever 54 and the handle 53 are respectively fitted with a convex or concave shape separately from the shaft and the bearing as shown in FIG. It is preferable because the lever 54 can be prevented from easily coming off by the reaction force of the tangential force generated at 39.

  As described above, the locking means is not limited to the mechanism in which the locking projection 39 and the hooking projection 55 are in contact with each other on the side surface and hooks in the rotation direction of the stopper 13, but is locked on the surface 37 that covers the spout of the inner container 12. A mechanism may be provided in which a recess is provided, and the hooking protrusion 55 on the back side of the lever 54 of the stopper 13 is fitted in the locking recess to interlock the inner container 12 and the stopper 13 by fitting in the vertical direction. The hooking protrusion may be on the inner container 12 and the locking recess may be on the lever 54.

  The lever 54 and the handle 53 may have a shape as shown in FIG. 35, in which a claw is provided on the back of the lever 54 and the upper surface of the handle 53, and the lever 54 is pushed from above the handle 53 and is engaged with each other. it can. In this case, the lever can be moved up and down using the space provided for fitting the claws. If this vertical movement is utilized, it is not necessary for the lever 54 to be elastically deformed in the release means in which the climbing projection 56 provided on the back side of the lever 54 climbs over the upper end of the cover 73. The possibility that the lever 54 may be damaged due to repeated elastic deformation can be eliminated. In addition, by adjusting the amount of catches, it is possible to realize a shape in which the lever 54 is detached from the handle 53 when the lever 54 is lifted more than necessary, and the lever 54 can be prevented from being damaged due to misuse. .

  Instead of the lever 54, the handle 53 may be provided with a telescopic bar 106 that can expand and contract in the radial direction of the stopper 13. The telescopic bar 106 has an elastic member such as a spring, and has a rounded end. A hooking projection 55 is provided on the back side of the telescopic bar 106, and normally the stretched state is maintained. When the handle 53 is rotated in a state where the telescopic bar 106 is extended, the hooking protrusion 55 comes into contact with the locking protrusion 39 provided on the surface 37 covering the spout of the inner container 12.

  In either case, either the main body container sealing means or the inner container sealing means is in a hard and easy-to-tight state. By utilizing the difference in the fastening force, the inner container 12 can be interlocked with the stopper 13 even if the shape does not have the locking means.

  For the same reason, seal members that generate different frictional forces on the seal members of the main body container sealing means and the inner container sealing means may be selected. The effect can also be achieved by selecting flat packing with different hardness.

  A structure such as a turnbuckle that loosens both sides of the sandwiched member at the same time and rotates them simultaneously by rotating the member sandwiched between the right and left screws may be used. For example, when the stopper 13 and the main body container 11 are connected, the right and left screws are cut off on both sides of the inner container 12, and the stopper 13 and the main body container 11 are respectively attached, the inner container 12 is rotated, thereby sealing the inner container. An interlocking structure in which the means and the main body container sealing means can be simultaneously tightened or loosened can be realized.

  When a double thread is used for the main body container sealing means, there are two positional relationships when the main body container 11 and the inner container 12 are fastened. When the inner container 12 may be fastened to any position, the inner container 12 is designed to be 180 °, thereby giving an easy-to-use impression. Further, when the inner container 12 is to be fastened to the main body container 11 at a certain position, it is preferable to provide an obstructing shape that cannot be screwed into the other screwing start position so that the inner container 12 is always screwed from a certain position.

  Further, the inner container 12 may be interlocked with the stopper 13 using a magnet. Furthermore, an electromagnet may be used so that the inner container 12 is interlocked with the stopper 13. In this case, for example, the electromagnet can be switched on and off by bringing the handle 53 and the lever 54 into contact with each other or separating them. Good, easy to use and preferred.
