Description

  The present invention relates to a means for attaching and detaching a cap and a lid of a cartridge tank for an oil stove.

  The cap provided at the fuel supply port of the cartridge tank for the oil stove is used with a lid with a small discharge valve. When the cartridge tank 2 is placed on the saucer in the oil stove, the shaft core 1 in the saucer shown in FIG. 1 (current example) pushes the valve opening of the small discharge valve, and fuel is supplied to the saucer to reach the required depth. Then it stops. Thereafter, supply and stop are repeated according to consumption. For the connection between the base and the lid, attachment / detachment means roughly classified into a screw type and a flange type are used.

  A screw type is often used as the attachment / detachment means, and a non-slip handle for easy attachment / detachment is attached to the outer periphery of the lid. [Patent Document 1] and [Patent Document 2] are prior applications of the applicant of the present application, and regarding the problems that occur when screws are used, the former discloses a technique for preventing oblique tightening of a screw thread and the latter for preventing excessive tightening. [Patent Document 3] discloses a technique in which one side of a flange fixed to a connection end of a base and a lid is connected with a hinge by a flange-type attaching / detaching means so as to be freely opened and closed, and a gasket is sandwiched between the two to fix the other side with a clasp. To do.

When attaching / detaching the lid to the base, the hand is easily soiled by the attached fuel, so that the hand is not soiled as much as possible, for example, when the tank is placed on the tray, the handle position of the screw-type lid and the flange of the flange-type lid The position is set so as not to be immersed in fuel.

  The requirements for the base and the lid are that proper tightening and reliable fuel leakage prevention can be obtained with simple operation, and hand dirt can be prevented. [Patent Literature 1] and [Patent Literature 2] are improved screw-type caps and lids, but the screw is also drawn without changing the operation of turning the lid and closing, so still pay close attention to the screwing operation. The problem that is necessary remains. The flange type of [Patent Document 1] is a technique with little hand dirt and excellent operability and ease of attachment / detachment, but there is a problem that the flange portion is structurally bulky and increases the labor for processing materials and parts. . An object of the present invention is to provide an attaching / detaching means that reliably prevents hand dirt by one touch without using a screw or a flange.

The present invention relates to a cap and a lid of a cartridge tank for an oil stove.
Protrusions are provided on the cylindrical surface forming the base,
The lid has a multi-layered cylindrical structure in which the upper lid member and the lower lid member are stacked in order, and when the upper lid member and the lower lid member are slidably stacked, the elastic force is applied to both members in the space formed by both members. Built-in elastic material,
In order to fix the lid to the base, at least two or two sets of locking materials energized by the elasticity of the elastic material are stored in the lid lower member.
When the lid is pushed into the base, the lower lid member moves while compressing the elastic material, and when the protrusion is exceeded, the base and the lid are locked by the locking material stored in the lower lid member. An oil stove base and lid are attached and detached with one touch to move the member in a direction in which the elasticity of the elastic material exceeds the protrusion and separate the base and the lid.

  The following effects were obtained using the base and lid of the present invention. Just by fitting the lid onto the base and pressing it down, the protrusion of the lever with elastic material automatically locks (locks) with the groove of the base, and the lid is fixed to the base. When the lock is released, the elasticity of the elastic material built in the upper and lower members of the lid works in the direction in which the lid lower member automatically gets over the projection of the cap, making it easy to remove the lid from the cap. Because this action can be attached and detached without reducing the certainty of leak prevention with a light force and one touch, the operability is improved.

  The structural features are that the one-touch base and lid do not have screws, which eliminates the problem of accuracy required for screw molding and contributes to the significant relaxation of the accuracy required for overall processing. Further, the problem of overtightening and slanting that are likely to occur at the time of screw-type screwing is solved, and since there is no flange compared to the flange type, there is no overhang, the bulk is low, and the number of parts required for the configuration is small.

  The locking material consisting of two levers or two sets of levers with a rotating plate housed in the annular groove of the lower lid member will not lock the base and lid unless the former activates all the spring-loaded projections at both ends of the lever. The structure is not released to increase safety, and the latter lever with a rotating plate is further improved in safety by adding to the former a structure that automatically locks (locks) to the other when only one is operated. As a result, it has become possible to provide and select a base and a lid that are easy to operate and have a secure and reliable attachment and removal.

  The present invention relates to a cap and a lid of a cartridge tank for an oil stove for attaching and detaching with one touch. When the lid is fitted and pushed down on the base formed with a projection on the cylindrical surface, the lower cover member with the handle moves along the upper cover member, the tip of the base contacts the gasket attached to the upper cover member, and the lower cover member When the protrusion of the base is exceeded, a locking function works between the locking material stored in the lid lower member and the groove on the back of the protrusion of the base, and the lid is connected to the base to reliably prevent fuel leakage. To release the locking function that separates the base and the lid, all the protrusions visible from the handle cut can be pushed.

  The base is bent inward to form a contact surface with the gasket, followed by a cylinder that fits into the upper cover member from the front end of the base, and a protrusion, groove, and cartridge tank in contact with the locking member on the lower cover side A cylinder for forming a fixed end is continuous. Since there is no need for a screw on the fitting surface between the lid upper member and the base, the outer diameter accuracy of each part forming the base may be such that smooth fitting with the lid upper and lower members is not hindered.

  The lid is formed of a multi-layered cylinder in which an upper lid member, a lower lid member, and a handle are sequentially stacked. The upper lid member closes the cylindrical tip, attaches a small discharge valve, attaches a gasket on the back, and bends the lower end of the cylinder outward. The lower lid member bends the upper and lower ends of the cylinder inward and outward, stores the locking material at the lower end, and stores the elastic material in the space where the upper and lower lid members overlap. The elastic force accumulated in the elastic material when the lid is attached to the base is urged to the contact surfaces of the gasket, the tip of the base, the locking material, and the groove on the back of the base projection.

  At least two locking members are incorporated in the lower lid member. The locking member is a lever having protrusions at both ends of the arcuate body, and one of the protrusions containing the elastic material is fitted in the hole of the bending surface of the lower lid member and held so as to move in the radial direction. The other protrusion is fitted in a hole on the lower surface of the cylinder of the lid lower member so as to be freely inserted and removed. When all the projections containing the elastic material are pressed, the locked state is released and the lid can be removed from the base. Using the lever's body as a balance with the protruding part of the handle's inner surface as a pivot point, the elasticity of the elastic material built in one protrusion passes through the body to the contact surface between the other protrusion and the outer peripheral surface of the base Energize.

  The locking member according to another aspect includes at least two sets of two connected members as a set. A set of shapes is provided with a bearing on the protrusion side containing the elastic material of the lever described in the section [0013], and a pivot having at least two contacts with a shaft core that is rotatably fitted to the bearing. It consists of a board. The rotating plate hits against the protrusion end surface that does not incorporate the elastic material of another set of levers having the same structure, and is arranged in the annular groove of the lower lid member so that all the locking members are connected in an annular shape.

  The elastic material in which the two sets of locking members arranged in a ring form an elastic force urges the contact surface between the projection on the other end sandwiching the body and the rotation plate connected to the projection and the lever on the other side. It is the posture of the rotating plate that determines the locking state between the protrusion of the locking member and the groove behind the protrusion of the base. When all the projections with elastic material are pressed, all the levers move in the same way to release the locked state, and when only one is pressed, the side pressed by the locking material that is not pressed to prevent the locked state from being released Since it works on the locking material, the base and the lid remain connected.

  Since the locking function disappears or becomes insufficient if the position of the locking material in the lid lower member is shifted, after the locking material is stored in the annular groove of the lid lower member, the folded surface and the opening surface of the groove are Enclose so that it is covered with the inner and bottom surfaces of the cylinder of the handle. Further, the outer cylindrical surface of the handle is overlapped so as to correspond to the hole or notch of the folded surface of the lower lid member, thereby providing a guide for assisting smooth movement in the radial direction of the protrusion containing the elastic material. The lid can rotate around the base regardless of whether or not it is locked.

  In order to connect the lid to the base, the lid is pushed down until the projection of the locking member stored in the lid lower member exceeds the projection of the base and fits into the groove behind the projection of the base. To remove the lid from the base, push the protrusion containing the elastic material and pull out the locking material from the groove of the base, and the elasticity of the elastic material built into the upper and lower members of the lid works on the lower member of the lid to make it exceed the protrusion of the base. The base and lid are separated and can be easily removed. The locking material also works as a slip lock for the handle. An oil-resistant synthetic resin material is used for the locking member and the handle, an oil-resistant elastic material is used for the gasket, and a metal material is used for the other members.

FIGS. 5A, 5B, and 5C are a plan view of the lower lid member and an arrow view and a perspective view of a cross section taken along the line ee of FIG. FIG. 6 is a perspective view of the lever. FIGS. 7A, 7B, and 7C are a plan view of the handle, and an arrow view and a bottom view of a cross section taken along line ff in FIG. FIG. 8 (A, B, C) shows the three states of operation of the locking members arranged opposite to each other in the cross-sectional view taken along the line gg of FIG.

  To connect the cap 3 and the lid 11 of FIG. 2 (A, B, C), the lid is pushed into the cap, the locking is completed with one touch, and the connection is made, and the protrusion containing the spring of the lever elastic material is pushed. With one touch, the locked state is released and the lid can be removed. The locking material built in the lid uses two levers with protrusions on both ends of the arc shape. Since no screws are used, there are no problems of overtightening and slanting. Moreover, it is not necessary to make a large connection surface unlike the flange type. In the following, description will be given based on each figure.

  As shown in FIGS. 3A and 3B, the base 3 fixed to the cartridge tank 2 has a multistage cylinder in which a plurality of bulges are formed concentrically on the surface. The folded end 5 is formed with the open end of the linear cylinder 4 facing inward, and the tip is used as a contact surface with the gasket 21 on the lid side. The cylindrical surface has no screws and is used as a fitting surface with the lid upper half 12. Following the cylinder, a projection 6 having a right-angled triangular cross section and a groove 7 are formed concentrically behind the projection, and a portion that also serves as a connection end to the cartridge tank is formed concentrically by a thick cylinder 8.

  As shown in FIGS. 4A and 4B, the upper lid member 12 closes the tip of the cylinder 17 to form an overhanging edge 15 and a blind lid 14 having a protrusion at the center, and a small discharge valve 16 is fixed at the center. . A turn 18 is formed in an annular shape outward from the rear end of the cylinder, and the inner surface of the cylinder is used as a fitting surface with the outer surface of the cylinder 8 of the base 3. A gasket 21 is inserted and fixed on the back side of the blind lid. When the lid is placed on the base, the lower end of the lid upper member is positioned in front of the slope of the annular projection 6 of the base.

As shown in FIGS. 5A, 5B, and 5C, the lid lower member 22 bends the upper and lower ends of the cylinder 23 inward and outward to form folds 24 and 25 in an annular shape. Two holes 26 and 27 are opened on each surface of the lower end of the cylinder and the lower end. The cylindrical inner surface is formed to such an extent that the outer peripheral surface of the turn 18 of the lid upper member 12 can slide smoothly. When the lid 11 is connected to the base 3, the coil spring 30 used as an elastic material urges the contact surface between the base 3 and the gasket 21 to prevent leakage.

  The lever 31 as a locking member in FIG. 6 has a resilient arcuate body 32 and has an outward projection 34 at one end and an inward projection 35 at the other. Both protrusions are fitted into a hole 26 at the lower end of the cylinder 23 of the lid lower member 22 and a hole 27 of the folded back 25 so as to freely enter and exit. A coiled spring 40 is built in the outward projection as an elastic material in a hole 33 formed from the inside. Since the outer surface of the arc-shaped body is brought into contact with the protruding portion 47 of the handle and the lever is moved like a balance, the movement of the outward projection is transmitted in the reverse direction to the inward projection. The two levers are the same shape, the same size, and asymmetrical.

  As shown in FIGS. 7A, 7B, and 7C, the handle 41 has the cylinders 42 and 43 concentrically overlapped with each other, the lower cylindrical outer peripheral surface 44 is attached with a slip stopper, and the lower end 25 of the lid lower member 22 has a hole in the folded 25 surface. A notch 48 communicating with 27 is made. When the inner circumferential surface 45 of the cylinder is press-fitted into the outer circumferential surface 28 of the lid lower member and is pushed in until the bottom surface 46 of the cylinder hits the upper end of the turnback 25, arc-shaped overhang portions 47 provided at two locations on the lower inner surface of the handle are formed. The folding of the lower lid member is pinched and fixed, and the inner surface and the bottom surface of the cylinder are used for bending the annular groove of the lower lid member. The bottom surface of the handle in this state restricts excessive movement of the two locking members stored in the annular groove, and helps smooth movement of the locking materials in the necessary direction.

  The assembly procedure of the lid 11 will be described with reference to the drawings. A spring 30 is placed on the turn 18 at the lower end of the upper lid member 12 and the lower lid member 22 is fitted. The inner diameter of the folding 24 at the upper end of the lower lid member is smaller than the outer diameter of the edge 15 of the blind lid 14 of the upper lid member, but it does not come back because it is press-fitted using the elasticity of folding. When the lid upper and lower members slide in the axial direction, the spring held in the space expands and contracts. When the outward projection 34 of the lever 31 with the spring 40 is fitted into the hole 27 on the folded 25 surface of the annular groove formed at the lower end of the lower lid member, the position of the lever is determined, and the inward projection 35 is fitted into the hole 26 for storage. The assembly is completed when the handle is press-fitted into the lid lower member so that the notch 48 of the handle 41 and the hole of the lid lower member coincide.

  The operation of attaching and detaching the lid 11 to the base 3 will be described. When the lid is fitted to the base, the cylinder 17 of the upper cover member 12 comes into contact with the base cylinder 4, and the inner tip of the inward projection 35 of the lever 31 built in the lower cover member 22 reaches the slope of the annular protrusion 6 of the base. Stop. When the lower lid member is pushed down, the gasket 21 comes into contact with the upper end of the folding back 5 of the base and compresses the spring 30 built in the upper and lower lid member. Furthermore, when the handle is pushed down, the tip of the inward projection of the lever is pushed by the slope of the base, the spring 40 built in the outward projection 34 is compressed and retracted into the annular groove, and when it exceeds the slope, it is inward by elasticity. The protrusion fits into the groove 7 behind the inclined surface and the locking is completed, and the lid is connected to the base. To remove, push the outward projections of all levers.

  8A, 8B, and 8C, the operation of the two levers 31 when the lid 11 is attached and detached will be described. In FIG. 8A, the outward projection 34 is pushed by the spring 40 and protrudes from the notch 48 at the lower end of the handle 41, and the inward projection 35 is fitted in the groove 7 of the base 3 and locked to the base. Is connected. In FIG. 8B, when all the outward projections are pushed, the inward projections are separated from the grooves and the locked state is released, and the lid lower member 12 is pushed by the spring 30 and the cap and the lid are separated beyond the annular projection 6. To do. FIG. 8C shows that the latching state is released by half only by pressing one outward projection. The projecting portion 47 of the handle 41 is in contact with the body 32 of the lever, thereby preventing unnecessary deformation of the body and serving as a pivot for the balance.

The force required for attaching and detaching the lid 11 is as light as that of the screw type, and the one-touch type has improved the operability because there is no problem of over-tightening and diagonal fastening of the screw type. In addition, the screw molding process is not required, which contributes to the simplification of the processing content during manufacturing. The outer surface of the outward protrusion 34 of the lever fits almost at the same level as the outer peripheral surface of the handle, and there is no fear that the lid will come off from the cartridge tank filled with fuel unless the outward protrusions of all the levers are pushed in consciously during the attaching / detaching operation. It is a highly safe structure.

  9A, 9B and 9C are a plan view of a base and a cover according to another embodiment, and a cross-sectional view taken along the lines hh and ii in FIG. 10A and 10B are a plan view of the base and an arrow view of a cross section taken along the line j-j in FIG. 11A and 11B are a plan view of the lid upper member and a cross-sectional view taken along the line kk in FIG. 12A, 12B, and 12C are a plan view of the lower lid member, and a cross-sectional arrow view and a perspective view taken along line ll in FIG. FIG. 13 is a perspective view of the lever, and FIGS. 14A and 14B are a plan view and a side view of the rotating plate. FIGS. 15A, 15B, and 15C are a plan view of the handle and an arrow view and a bottom view of a cross section taken along the line m-m in FIG. FIGS. 16A, 16B, and 16C show the three states of operation of the two sets of locking members in a cross-sectional view taken along line nn in FIG.

  To connect the base 3 and the lid 51 in FIGS. 9A, 9B, and 9C, the lid is pushed into the base in the same manner as in the first example, and the connection is made with one touch. It can be released and the lid can be removed. In the lid, two sets of locking materials, each having a shape similar to that of Reference Example 1 and having a lever attached to one of the protrusions and a rotating plate, are stored and used. The effect obtained from this example is equal to or higher than that of Cited Example 1. In the following, description will be given based on each figure.

  FIGS. 10A and 10B show the cap 3 fixed to the cartridge tank 2, but the same reference numerals are used because the role is almost the same as in FIG. 3A and FIG. The description of Example 1 is referred to. The open end of the linear cylinder 4 is used as a contact surface with the gasket 61 on the lid side.

  As shown in FIGS. 11A and 11B, the lid upper member 52 closes the tip of the cylinder 57 to form a protruding lid 55 and a blind lid 54 having a projecting portion at the center to fix the small discharge valve 16 at the center. To do. An overhang 58 is formed in an annular shape outward from the rear end of the cylinder to round the end, and the inner surface of the cylinder is used as a fitting surface with the outer surface of the cylinder 8 of the base 3. The gasket 61 is inserted and fixed on the back side of the blind lid. When the lid is fitted on the base, the lower end of the upper lid member is positioned in front of the slope of the annular projection 6 of the base.

  As shown in FIGS. 12A, 12B, and 12C, the lid lower member 62 folds the opening 64 with the upper end of the cylinder 63 narrowed down and the lower end outward to form an annular groove by folding 65 to store the locking material. To do. Two holes 66 and cuts 67 are made on each surface of the lower end of the cylinder and the lower end. The cylindrical inner surface is formed to such an extent that the outer peripheral surface of the overhang 58 provided on the lid upper member 52 can slide smoothly. When the cover 51 is fitted to the base 3, the elasticity of the coil spring 70 made of an elastic material is urged to the gasket 61 to prevent leakage.

  The lever 71 of FIG. 13 has an arcuate body 72 having elasticity and flexibility, and includes a bearing 90 at one end, an outward projection 74 with a large pressing surface, and an inward projection 75 at the other end. Both protrusions are fitted so that they can freely enter and exit into a hole 66 at the lower end of the cylinder 63 of the lid lower member 62 and a notch 67 on the folded-back 65 surface. A coiled spring 80 made of an elastic material is built in the hole 73 formed from the inside of the outward projection.

  As shown in FIGS. 14A and 14B, the rotating plate 91 has a shaft 92 that is rotatably mounted on the bearing 90 of the lever 71, and a claw having an inner contact 93 and an outer contact 94 on one side. The tip angle of is 45 °. The rotating plate has a role of determining the locking state when the lid 51 is attached to the base 3, and the claw is locked when the posture (contact position between the inner contact and the outer contact) with respect to the lever that is not connected is changed. Can be changed.

As shown in FIGS. 15A, 15B and 15C, the handle 81 has cylinders 82 and 83 concentrically overlapped to prevent the outer peripheral surface 84 of the outer cylinder from slipping, and a notch 67 on the folded 65 surface at the lower end of the lid lower member 62. A notch 88 that communicates in the opposite direction is provided. In addition, a locking claw 95 is provided on both sides of the upper end of the inner cylinder with cuts 85 to give elasticity, and serves as a retaining when fitted to the lid lower member 62. The cylindrical inner surface and the bottom surface of the handle are used for bending the annular groove of the lower lid member. The bottom surface 86 of the handle in this state restricts the upward movement of the two sets of locking members stored in the annular groove, and helps smooth movement of the locking materials in the necessary direction.

  The assembly procedure of the lid 51 will be described with reference to each drawing. A spring 70 is placed on the overhang 58 at the lower end of the upper lid member 52 and the lower lid member 62 is fitted. The inner diameter 64 of the upper end of the lid lower member is slightly smaller than the outer diameter of the edge 55 of the blind lid 54 of the upper lid member, but it is press-fitted using the elasticity of the folded portion. When the lid upper and lower members are slid in the axial direction, the spring 70 held in the gap expands and contracts. The outward projection 74 of the lever 71 with the spring 80 is fitted into a notch 67 on the surface 65 of the annular groove of the lower lid member to determine the position of the lever, and the inward projection 75 is fitted into the hole 66.

  A large pressing surface of the outward projection 74 of the lever 71 is used as an operation button biased by a built-in spring 80. The inward projection 75 is pressed against the outer surface of the cylinder 63, and a claw comprising an inner contact 93 and an outer contact 94 of the rotating plate 91 is inserted into a gap surrounded by the inner surface 65 and the lever outer surface. Two sets are used as one set of locking materials. The locking material is the same shape, the same size and asymmetrical.

  When the handle 81 is fitted into the outer surface of the cylinder 63 of the lower lid member 62 and the turn-up surface 65 of the annular groove formed at the lower end, the notch 88 on the outer cylinder 83 surface of the handle is aligned with the notch 66 of the lower lid member. When the upper end of the locking claw 95 provided on the inner cylinder 82 of the handle is press-fitted until the projection 89 formed on the outer surface of the cylinder of the lid lower member exceeds the assembly, the assembly is completed.

  An operation when the lid 51 is attached to the base 3 will be described. When the lid is placed on the base, the cylinder 57 of the upper cover member 51 comes into contact with the cylinder 4 of the base, and the inner tip of the inward projection 75 of the lever 71 built in the lower cover member 62 reaches the slope of the annular projection 6 of the base. Stop. When the handle is pushed down, the gasket 61 comes into contact with the upper end of the folding back 5 of the base and compresses the spring 70 built in the lid upper and lower members. Further, when the lever is pushed down, the inner tip of the inward projection of the lever is pushed by the slope of the base, and the spring 80 built in the outward projection 74 is compressed and retracted into the annular groove. Is fitted in the groove 7 behind the inclined surface and the locking is completed, and the lid is connected to the base. When removing, the operation button on the outward projection of the lever may be pushed.

  The operation of the two sets of locking members when the lid 51 is attached / detached will be described with reference to FIGS. 16 (A, B, C). The inner surface 63 and the turn-back 65 of the annular groove in which the locking member is stored in the drawing are drawn with a two-dot chain line. The two sets of locking members comprising the lever 71 and the rotating plate 91 housed in the annular groove of the lid lower member 62 can move independently for each set. The sets are arranged so that the first set of levers 71 and the second set of rotating plates 91 are in contact with each other as much as possible. As a result, when both locking materials are moved, the lid can be attached and detached without any problem, but when one locking material is moved, an interference function that stops the movement from the other locking material works and the lid is separated. Absent.

  FIG. 16A corresponds to the state of the lid 51 that has been fitted into the base 3 and has been connected. The outward projection 74 is pushed by the spring 80, and the push button protrudes from the notch 67 of the lower member 62. A claw composed of an inner contact 93 and an outer contact 94 of the rotating plate 91 enters between the inner surface 65 of the lower lid member and the outer surface of the inward protrusion, and the tip of the inward protrusion 75 is fitted into the groove 7 of the base to be locked. When completed, the base and lid are connected. The lid that is not fitted to the base also has the same shape as this figure.

FIG. 16B corresponds to a state in which the base 3 and the lid 51 are disconnected. When all the outward projections 74 are pushed against the spring 80, the connected rotating plate 91 rotates around the shaft core 92 and changes its posture. The positional relationship between the inward projection 75 and the inner and outer contacts 93 and 94 formed on the rotation plate is such that the outer angle of the inward projection is pushed to the surface between the inner and outer contacts from the state in which the inner and outer contacts are in contact with the original inward projection. Since the lever 71 rotates outward while deforming the body 72 with the outward projection as a base point, the lever t shifts to a state in which the outer contact thickness t portion is sandwiched between the inward projection and the turn-back 65 of the annular groove, The locked state is released and the base and the lid are separated.

  The change in the posture is that the force that rotates the inward projection 75 transmitted from the outward projection 74 outwardly slides the surface between the inner and outer contacts 93, 94 that are inclined by the rotation of the rotation plate 91. It is. When the bent portion at the front end of the rotating plate enters between the inner surface of the folded-back 65 of the lower lid member 62 and the outer surface of the inward projection, the movement of the locking member is completed. Further, the outer contact set to the thickness t is for pulling the protruding portion of the inward projection from the hole 66 on the inner cylinder 63 to the annular groove side by a length necessary for releasing the locked state, and as a complete pull-in preventing stopper. Also work. The angle α of the plane between the inner and outer contacts that changes with the movement of the contact position is about 45 °, but the numerical value is determined by the relationship between the lever, the rotating plate, and the annular groove, and is not a definite value.

  FIG. 16C shows that when only one outward projection 74 is pressed, the inner and outer portions 93 and 94 of the rotation plate 91 on the non-pressing side remain behind the inward projection 75 on the pressed side [FIG. See A)], and the lever 71 on the pushed side is restricted from rotating outward, and the inward projection cannot move the length necessary for releasing the locked state. The rotating plate on the pressed side rotates, but there is no force transmitted to the inward projection on the non-pressed side when pushing the outward projection, and the outer angle of the inward projection slides on the plane between the inner and outer contacts There is not enough force, and the displacement is just enough to contact the inside. As a result, the pressed side receives interference from the non-pressed side to prevent the locked state from being released, and the connection between the base and the lid is continued.

  The force required for attaching and detaching the lid 51 is as light as that of the screw type, and the one-touch type has improved the operability because there is no problem of over-tightening or oblique fastening of the screw type. Workability has been improved as long as there is no screw molding process, and the structure has two sets of locking materials consisting of a lever and a rotating plate, so that the cap and lid cannot be separated except for the push button operation of all locking materials. Therefore, safety could be further improved.

  Usually, the opening / closing means used for the entrance / exit of the portable container includes a lid type to be externally inserted into the base and a plug type to be internally inserted. Although the amount of protrusion from the container surface is large in the former and small in the latter, the former is overwhelmingly used. Although the present invention also belongs to the former, there is no problem with rotation because no screws are used, no need for flanges, hinges, and clasps, small size and simple structure, easy attachment and detachment, and reliable liquid leakage prevention Of course, it has many features that the safety is high because the lid cannot be removed unless all the locking members are moved. The base and lid of the present invention are not limited to oil stoves but can be widely applied to non-pressure liquid containers.
