Description

  The present invention relates to a container with a cap that is closed in a state where a cap-side fitting foot is fitted to a take-out port arranged at an eccentric position on the container main body side. The present invention relates to a lid closing guide device for automatically guiding and positioning a leg portion to a position where it is fitted to a take-out port.

  Conventionally, as a container with a cap in which a take-out port is arranged at an eccentric position on the container main body side, a so-called quantitative take-out container or a shake-out container configured to take out an object to be contained every predetermined amount is known ( For example, see Patent Document 1). In this case, since the outlet is formed at an eccentric position, a cap for opening and closing only the outlet at the eccentric position is formed integrally with the container body side, or the entire upper end surface including the outlet is formed. A cap for opening and closing is also formed integrally with the container body side. Here, closing of the takeout port is realized by covering the upper surface of the takeout port with a cap, and a part of the cap is integrally molded with the container body side by synthetic resin molding, and the hinge is used as a fulcrum. The cap can be flipped up and opened.

  Further, there has been proposed one that not only simply covers the upper surface of the takeout port, but also allows the middle foot part to be fitted into the takeout port (see, for example, Patent Document 2). In this case, the middle foot part protrudes from the inner surface of the cap, and since the takeout port is in an eccentric position, the cap is formed integrally with the container body side as in the above-mentioned Patent Document 1, and can be opened and closed by pushing and flipping up. Thus, the positioning of the middle foot portion and the outlet is unnecessary.

  By the way, with the cap of the open lid type by flipping up as described above, even when the container is turned upside down and the contained object is taken out from the takeout port, the cap is attached to the periphery of the takeout port, although it is in the state of being flipped up. Therefore, there is a risk that the object to be taken out may be hindered due to the object to be put on or attached to the cap. For this reason, a completely separated type cap is formed separately from the container body side, that is, a normal type that can be opened and closed by a rotational screw-in type with respect to the container body and is completely separated from the container body side when the lid is opened. It is possible to do.

  However, since the takeout port is formed at the eccentric position, even if the middle foot part is formed on the completely separated type cap, the middle foot part is turned into the above-mentioned eccentric position takeout port while being screwed in rotation during the closing operation. It is virtually impossible to fit inside. Thereby, when a completely separated type cap is employed, means for securing airtightness by the middle foot portion cannot be employed. On the other hand, since the above-mentioned fixed quantity extraction containers and the like in which the extraction port is formed at an eccentric position are usually intended to be contained in a powdery or granular form as the contents to be taken out, When not in use, that is, when the lid is closed, it is necessary to ensure a certain degree of airtightness of the outlet.

  This invention is made | formed in view of such a situation, The place made into the objective is by fitting of the fitting leg part with respect to the taking-out port provided in the eccentric position using the cap of a complete separation type. Cap closing guide device in a cap-equipped container that can be automatically closed by a simple lid operation without requiring troublesome positioning operation to ensure airtightness. Is to provide.

In order to achieve the above object, in the present invention, a container main body disposed on an end face on one side in the central axis direction so that a takeout port opens at an eccentric position with respect to the central axis, and the center with respect to the takeout port In the closed state in which the fitting foot for fitting from the axial direction to maintain airtightness is provided on the inner surface and the end surface on one side in the central axial direction of the container body is covered, the fitting foot is located with respect to the take-out port. A cap closing guide device provided in a cap-equipped container provided with a cap that is in a fitted state, wherein the fitting foot portion serves as an outlet for the eccentric position when the cap is closed. The cap is guided and positioned so as to reach the fitted closed state. Specifically, the fitting legs, disposed on an arc of a certain arc the same diameter passing through the eccentric position where the outlet and about said center axis is located, in the above-described upper Symbol closed state Provided so as to protrude in the radial direction with respect to one of the inner peripheral surface of the cap and the outer peripheral surface of the container main body that are opposed to each other in the radial direction around the central axis. When the guided convex part comes into contact with the guided convex part from the central axis direction and is provided so as to protrude in the radial direction with respect to the other circumferential surface and opposite to the guided convex part Guiding means for moving and guiding the cap to position the cap so that the fitting foot fits into the take-out port by guiding and guiding the movement of the guided convex portion. The guiding means is a guiding path projecting stepwise in the radial direction, and receives the closing operation force on the cap from the central axis direction to guide and guide the guided convex portion by sliding in the circumferential direction. a mountain-shaped guide path for rotation guide cap the fitting foot section outlet to up if the rotational position fitted becomes opposite to Rukoto to the central axis direction to the central axis by, the mountain-shaped guide path The guided convex portion guided by the guide enters and guides the guided convex portion toward the other side in the central axis direction so that the fitting foot portion at the fitting rotational position is fitted into the take-out port. cormorants, and that a vertical guide path for moving guiding the caps of the fitting rotational position to the closed lid state toward the central axis direction other side (claim 1).

In the case of this invention, when the cap is brought closer to the end surface on the one side in the central axis direction of the container body from the central axis direction, the guided convex portion comes into contact with one of the mountain-shaped guide paths. Due to this contact, the movement direction is changed so that the guided convex portion slides in the circumferential direction, and the cap rotates around the central axis along with the sliding and is guided to the fitting rotation position. When the fitting rotation position is reached, the guided convex portion enters the vertical guiding path, and the guided convex portion is guided and guided toward the other side in the central axis direction by the vertical guiding path. Along with this, the cap is guided to move until its fitting foot is fitted to the take-out port. Thereby, a cap will be in a closed state in the state which the fitting leg part fitted with respect to the taking-out port arrange | positioned in an eccentric position. In order to such a closed state, without any special positioning operation, only a simple closing operation of only putting the cap on the container body, by the mountain-shaped guide path of the guiding hand stage movement of the central axis for the engagement of the rotation guide and, fitting the vertical guide path Goashi portion for rotational positioning of the circumferential direction of the caps to fit the rotational position by the guiding induction of the guiding projections Guidance is automatically performed and the lid can be closed, which is extremely convenient. And the airtightness in a closed state can be reliably maintained by the fitting with respect to the taking-out port of the fitting foot.

  As the mountain-shaped guideway in the present invention, a vertex on one side in the central axis direction and a pair of slopes composed of inclined surfaces extending toward both sides in the circumferential direction across the vertex and inclined toward the other side in the central axis direction. The longitudinal guiding path may be formed in a concave groove shape so as to bend from the end side of the ramp and restrict the moving direction of the guided convex portion in the direction of the central axis. ). By doing in this way, the structure of the mountain-shaped taxiway of the said invention can be actualized and the function can be implement | achieved reliably. In other words, after the guided convex portion abuts on an arbitrary circumferential position of the mountain-shaped guide path, the guided convex section is slid along the inclined path to rotationally guide the cap and rotationally guided to the end position. Then, it reaches the above-mentioned fitting rotation position, and after that, the guided convex part enters the concave groove-shaped vertical guiding path, so that the fitting foot part is fitted into the take-out port to the closed state. Travel guidance will be performed.

  Further, at least two mountain-shaped taxiways are provided as the guiding means in the invention, and the vertical taxiway is formed between the ends of both mountain-shaped taxiways adjacent in the circumferential direction. (Claim 3). By doing so, it is possible to guide and guide more smoothly than the case where the guided convex portion is rotationally guided in the circumferential direction by one mountain-shaped guide path if the distance is the same in the central axis direction. The larger the number of mold guide paths, the less the required amount of rotational movement of the cap in the circumferential direction from the position where the guided convex part first contacts to the fitting rotation position, and quicker and easier closure. The operation can be performed. In addition, it is possible to easily form a groove-shaped vertical guiding path between the mountain-shaped guiding paths adjacent in the circumferential direction. Thus, in the case of providing at least two mountain-shaped taxiways, the same number of the mountain-shaped taxiways are provided as the fitting feet, and the circumference around the central axis is the same as the number. The fitting feet are arranged at each circumferentially equally divided position, and the number of fitting feet is a specific arc passing through the eccentric position where the take-out port is arranged around the central axis. It can arrange | position on the circular arc of the same diameter as (Claim 4). By doing in this way, the effect | action by said Claim 3 can be obtained more reliably. In this case, the number of guided protrusions is the same as the number of the mountain-shaped guide paths, and the fitting feet are arranged at circumferential positions equally divided into the same number as the number around the center axis. You may make it arrange | position in the same circumferential direction each position. That is, at least one guided convex portion is sufficient, but by providing the same number as the mountain-shaped guide path and the above arrangement, each guided convex portion is in contact with the mountain-shaped guide path. As a result, the rotation stability at the time of rotation guidance can be improved.

  Furthermore, in the above invention, it is possible to form engagement protrusions that are engaged with each other during the closing operation on both the inner peripheral surface of the cap and the outer peripheral surface of the container body. . And as a both engagement convex part, a cap side engaging convex part engages with a container main body side engaging convex part in the state by which the said guided convex part was guided to the fitting rotation position by the mountain-shaped guide path. , Temporarily stopping the movement of the cap to the other side of the container body in the central axis direction, while the cap-side engagement convex part receives the pressing force to the other side of the central axis direction against the cap, the container-side engagement convex part The formation position and the shape are set so as to overcome the above and reach the closed state (Claim 5). In this way, when the guided convex portion comes into contact with the mountain-shaped guide path from an arbitrary rotational position and is guided to rotate to the fitting rotational position, the engagement convex portions described above engage with each other. The movement of the cap is temporarily stopped. Next, when the cap is pressed with a slight pressing force, the fitting foot fits into the take-out port and the lid is closed. Thus, at the conversion point (boundary) between the rotation guide in the circumferential direction and the movement guide toward the other side in the central axis direction, the moderation feeling due to the above engagement and the application of the pressing force for the progress of the closing operation Can be given to the user, and the user can complete the closing operation with certainty.

As described above, according to the cap closing guide device in the cap-equipped container according to any one of claims 1 to 5, the container main body side arranged at the eccentric position using the completely separated cap When the lid is in the closed state with the fitting foot fitted in the take-out port of the container, it is guided by simply closing the cap so that the cap is placed on the container body without performing any special positioning operation. a rotary guide for the circumferential direction of the rotational positioning of the caps to fit the rotational position by the guiding induction of the guiding projections by mountain-shaped guide path of the hand stage, fitting of Goashi portion fitted by vertical guide path The movement guide in the direction of the central axis for matching is automatically performed and the lid can be closed. As a result, it is possible to easily realize to reliably maintain and improve the airtightness at the take-out port in the closed state.

  According to the second aspect of the present invention, the above-described invention can be made more concrete and the effect can be realized with certainty by the mountain-shaped guideway provided with a pair of ramps and the concave guideway. .

  According to the third aspect of the present invention, it is possible to smoothly guide the rotation of the guided convex portion in the circumferential direction by the mountain-shaped guide path, and the more the number of the mountain-shaped guide paths, the more the fitting rotation. The amount of rotational movement of the cap in the circumferential direction required to reach the position can be reduced, and the lid closing operation can be performed more quickly and easily. In addition, it is possible to easily form a groove-shaped vertical guiding path between the mountain-shaped guiding paths adjacent in the circumferential direction. And according to Claim 4, such an effect can be acquired more reliably.

  Further, according to the fifth aspect of the present invention, the two engaging projections are connected to each other in the middle of the guide guidance process of the cap, that is, at the boundary between the rotation guide in the circumferential direction and the movement guide toward the other side in the central axis direction. It is possible to give the user a sense of moderation associated with the engagement and riding, and to complete the closing operation with certainty to the user.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 4 show a fixed quantity takeout container 1 as an example of a capped container according to an embodiment to which the cap closing guide device of the present invention is applied. 1 shows an appearance, FIG. 2 shows an enlarged state cut along the line AA in FIG. 1, FIG. 3 shows an exploded state viewed from diagonally above, and FIG. 4 shows an exploded state viewed from diagonally below. This fixed quantity take-out container 1 includes a container main body 2 and a cap 3 which is separated from the container main body 2 and is completely separated. The cap 3 has a peripheral wall 32 extending from the outer periphery of the top plate portion 31 and projecting middle foot portions 33, 33,... As fitting feet from the inner surface. The middle leg 33 on the cap 3 side is fitted into the take-out port 4 on the second side so that airtightness is maintained. This fixed quantity take-out container 1 has a cylindrical appearance whose central axis X extends in the vertical direction, and the container body 2 is composed of a storage container part 21, a weighing part 22, a container top 23, and a bottom cap 24. ing. Each component including the cap 3 is formed of a synthetic resin. Hereinafter, each component will be described in detail. In the following description, the central axis X direction (the direction in which the central axis X extends) is simply referred to as the vertical direction, or one side in the central axis X direction is referred to as the upper side and the other side is referred to as the lower side. There is also.

  The storage container portion 21 is a cylindrical container having a bottom surface opened and a top surface closed by a top wall 211, and the bottom surface opening 212 is closed by a screw-type bottom cap 24 so as to be opened and closed. The bottom cap 24 is opened to store and fill an object to be stored (for example, powder, granule, or granular medicine) in the storage container portion 21, and then closed and sealed. . A communication hole (not shown) is formed in the top wall 211 so as to penetrate through the communication hole, and an object to be stored is dropped into a measurement chamber (not shown) of the measuring unit 22 through which the fixed amount of object is measured. It has become. The measurement mechanism will be described later.

  The weighing part 22 is built in the container top 23, and the container top 23 is coupled to the receiving container part 21 so as to be rotatable around the central axis X in a state where the weighing part 22 is built. The container top 23 covers the top wall 211 and the weighing unit 22 and closes, and the container top 23 is hung from the outer periphery of the top plate 231 and arranged at the outer peripheral position of the weighing unit 22. The outer peripheral cover wall 232 and the peripheral wall 233 projecting upward from the outer peripheral side position of the top plate portion 231 are provided. The top surface of the top plate portion 231 constitutes an end surface on one side of the container body 2 in the central axis X direction.

  The top plate portion 231 is formed with a takeout port 4 that penetrates in the vertical direction and opens upward. The take-out port 4 is constituted by an internal space of a tip cylinder 41 protruding upward from the top plate portion 231, and the center position thereof is a specific centering on the central axis X like the later-described measuring rod of the measuring portion 22. It is arranged and set at an eccentric position with respect to the central axis X so as to be positioned on the arc R (see FIG. 5A). The outer peripheral cover wall 232 constitutes the outer peripheral surface of the container main body 2 together with the storage container portion 21, and the inner peripheral surface on the lower end side thereof is externally fitted to the outer peripheral surface of the storage container portion 21, and the central axis X as described above. It is coupled so that it can rotate around. As such coupling, although not shown in the figure, for example, an engagement means or the like by a combination of a concave circumferential groove and a ridge engaging with the circumferential groove is employed.

  Here, the measuring mechanism by the measuring unit 22 is roughly as follows. For example, as the simplest measuring mechanism, the communication hole of the top wall 211 is arranged on the specific arc, and a measuring rod communicating with the take-out port 4 is formed in the measuring unit 22 to measure the container top 23. Rotating around the central axis X together with the portion 22 allows the measuring rod to be in communication with the communication hole, or to be disconnected, and the lower surface of the measuring rod is closed by the top wall 211 to close the communication position. The rotational position can be switched to the position. The fixed quantity take-out container 1 closed with the cap 3 is turned upside down from the upright state (the state shown in FIGS. 1 and 2 with the cap 3 up) to the inverted state (the state with the cap 3 down). Then, when the container top 23 is rotated to the above communication position, the object to be stored falls into the measuring tub through the communication hole. Next, when the container top 23 is rotationally converted to the above-mentioned closed position, the container is partitioned from the container 21 in a state in which the container is filled with the object to be stored. The inside of the part 21 is separated. When the cap 3 is opened, the contents to be stored in the measuring bowl, that is, the fixed quantity to be stored are taken out from the outlet 4 communicating with the measuring bowl. As described above, in order to perform quantitative extraction, the extraction port 4 needs to be arranged at an eccentric position on a specific arc.

  The outer peripheral surface 234 of the peripheral wall 233 constitutes the upper end side outer peripheral surface of the container body 2, and the outer peripheral surface 234 of the peripheral wall 233 (hereinafter referred to as “container-side outer peripheral surface 234”) and the peripheral wall 32 of the cap 3. The closing guide device of the present invention is disposed on the inner peripheral surface 321 (hereinafter referred to as “cap-side inner peripheral surface 321”). That is, the lid guide device includes a guided convex portion 5 and guiding means 6 for guiding and guiding the guided convex portion 5, and the guided convex portion 5 is arranged on the container side outer peripheral surface 234 (on the container body 2 side). ) And the cap side inner peripheral surface 321 (cap 3 side), and the guiding means 6 is formed on the other. In order to make this lid-closing device in a closed state in which the middle foot portion 33 is fitted into the upper end opening 42 of the take-out port 4 provided in the eccentric position, without performing a special positioning operation, By simply covering the cap 3 from above the container top 23 from any rotational position with respect to the central axis X, the closed state as described above can be realized.

  In the present embodiment, the guided convex portion 5 is formed on the cap side inner peripheral surface 321, and the guiding means 6 is formed on the container side outer peripheral surface 234. Accordingly, the guided convex portion 5 is first guided by the guiding means 5 only by covering the lower surface (inner surface) of the top plate portion 31 of the cap 3 with the upper surface of the top plate portion 231 of the container top 23 facing each other in the vertical direction. 6 to guide and guide the cap 3 around the center axis X to the fitting rotation position where the middle foot 33 is opposed to the take-out port 4 in the vertical direction. Similarly, the guide convex portion 5 is guided and guided downward by the guide means 6, and the cap 3 is dropped to the container top 23 side so that the middle foot portion 33 is fitted into the takeout port 4. .

  More specifically, four middle legs 33, 33,... (See FIG. 5 (b)) are hung from the lower surface (inner lower surface) of the top plate portion 31 of the cap 3, and formed on the cap side. .. Are formed on the circumferential surface 321 as the guided convex portion 5. The four middle foot portions 33, 33,... Are each on a specific arc R centered on the central axis X, and the specific arc R is equally divided into four, like the measuring rod 22 and the outlet 4 of the measuring unit 22 described above. The vertical ridges 51, 51,... Are arranged at the outer peripheral side positions of the respective middle foot portions 33, that is, the same as the middle foot portions 33, 33,. It arrange | positions so that it may be located in each position of the circumferential direction. On the other hand, on the container-side outer peripheral surface 234 of the container top 23, four chevron-shaped guide step portions 61, 61,... (See FIGS. 3, 4 and 5A) are formed as the guiding means 6, and such guides are formed. The step portions 61, 61,... Guide and guide the vertical ridges 51.

  As shown in FIG. 6A, each of the guide step portions 61 has a highest vertex 611 formed at the central position, and extends on both sides in the circumferential direction across the vertex 611, and gradually decreases toward the lower side. 612 and 612 are formed, and the longitudinal guide path 62 in which the longitudinal ridge 51 is dropped downward between the two guide step portions 61 and 61 that are adjacent to each other in the circumferential direction is formed in a concave groove shape. Is formed. FIG. 6A shows one round (0 ° to 360 °) with the circumferential installation position (fitting position T) of the outlet 4 shown in FIG. 5A as 0 ° in the circumferential direction with respect to the central axis X. Is shown in an expanded state. Then, as shown in FIG. 5 (a), the vertical guiding path 62 is set at the outer peripheral side position of the outlet 4, and the other three vertical guiding paths 62, 62,... It is arranged and set at a position on the circumference every 90 ° of the inner angle.

  Further, an engaging convex portion 63 is formed on the outer peripheral surface of each guide step portion 61, while an engaging convex portion 322 is formed on the cap side inner peripheral surface 321. Each engaging convex portion 63 is at a predetermined level position in the vertical height (width in the central axis X direction) of the peripheral wall 233, and the lower end of each vertical convex strip 51 extends from each inclined path 612 to the vertical guiding path 62 as will be described later. The position is set at a position where it comes into contact with the engaging convex portion 322 of the cap side inner peripheral surface 321 and temporarily stops due to interference when the bent position is reached.

  Here, the inner diameter of the cap-side inner peripheral surface 321 is the bulging width of each guide step portion 61 to the outer peripheral side with respect to the outer diameter of the container-side outer peripheral surface 234 (the width projected to the outer peripheral side to form a step). ) Is approximately equivalent to the total dimension obtained by adding the dimension equivalent to twice, that is, a dimension obtained by adding a slight margin to the above total dimension. Further, the projecting dimension of each vertical ridge 51 is a dimension substantially corresponding to a half of the differential dimension obtained by subtracting the outer diameter of the container-side outer peripheral surface 234 from the inner diameter of the cap-side inner peripheral surface 321, that is, the dimension thereof. Is set to a dimension obtained by subtracting a slight dimension to avoid interference with the container-side outer peripheral surface 234. And the bulging width of each inclined path 612 which comprises each guide step part 61 is set to such an extent that each said vertical protruding item | line 51 contacts reliably and is guided and guided by sliding or sliding. This bulging width corresponds to the depth of the concave groove of the vertical guide path 62. If the vertical ridge 51 is fitted in the vertical guide path 62, the vertical ridge 51 is prevented from moving in the circumferential direction on the lower side ( The depth of the groove to be moved only to the outer peripheral cover wall 232 side in the central axis X direction is configured. The vertical height of the vertical guide path 62 (the dimension in the direction of the central axis X) is set so as to have at least a dimension corresponding to a fitting depth that fits into the take-out port 4 of the middle foot 33. Desirably, the middle foot 33 and the tip tube 41 do not interfere with each other with respect to the above-mentioned fitting depth at a position where two engaging projections 322 and 63 described later stop and temporarily stop. What is necessary is just to leave the dimension of the central axis X direction which added the allowance.

  Next, the lid closing guidance of the cap 3 by the above-mentioned vertical ridges 51, 51, ... and the guide step portions 61, 61, ... will be described with reference to FIG. When the user puts the cap 3 on the top of the container top 23 of the container body 2 as shown in the uppermost side of FIG. 7, the vertical ridges 51, 51,. It hits any part of the circumferential direction of the step portions 61, 61,... (See stage S1 to stage S2 in the figure). FIG. 7 corresponding to the second stage S2 from the top of FIG. 7 and FIG. 8 corresponding to this stage 2 illustrate the case where the lower ends of the vertical ridges 51 abut against the inclined path 612 of the guide step portion 61. When the lower end of each vertical ridge 51 abuts against and comes into contact with the inclined path 612, each vertical ridge 51 slides along the inclined path 612 by the action of gravity or the like and easily moves to the vertical guide path 62 side, Along with this, the cap 3 is rotationally displaced about the central axis X from the contacted position to the fitting rotational position T (rotational displacement in the direction indicated by the one-dot chain line arrow in FIG. 8). Therefore, it is desirable to mold the ramp 612 so as to have a smooth surface when molding the synthetic resin. Then, when the cap 3 is rotationally displaced to the fitting rotation position T where each vertical ridge 51 is positioned at the upper entrance of the vertical guide path 62, any one of the four middle legs 33 opens the upper end of the take-out port 4. It is located on the upper side of 42 and coaxial with the takeout port 4 (see FIG. 9A showing the state corresponding to the stage S3 and the stage 3). In this state after the rotational displacement, the cap 3 has the above-mentioned vertical ridges 51 as a result of the engagement convex portions 322 of the cap side inner peripheral surface 321 coming into contact with the engagement convex portions 63 of the container side outer peripheral surface 234. It is temporarily stopped in a state where it is located at the upper entrance of the vertical guiding path 62, that is, in a state where one middle leg 33 is located above the upper end opening 42 of the take-out port 4 and coaxial with the take-out port 4.

  Then, when the user pushes the cap 3 slightly from the top to the bottom from this state, the engaging convex portion 322 on the cap 3 side gets over the engaging convex portion 63 of the container-side outer peripheral surface 234, and each vertical convex portion Each of the vertical ridges 51 is guided to the vertical guide path 62 and falls until the strip 51 enters the vertical guide path 62 from the top to the bottom, and the lower end of the peripheral wall 32 of the cap 3 contacts the top plate portion 231 of the container top 23. It will be. As a result, the middle foot portion 33 enters from the upper end opening 42 of the takeout port 4 and fits into the takeout port 4, and the cap 3 covers the upper end surface of the container top 23 and is completely closed (stage S 4). And FIG. 9B showing a state corresponding to the stage 4). In this state, the engaging convex portion 322 of the cap-side inner peripheral surface 321 that has overcome the engaging convex portion 63 of the container-side outer peripheral surface 234 is locked by the engaging convex portion 63 that has been overcome, and thus the cap 3 Movement to the open side (upper side) is restricted, and the cap 3 is maintained in the closed state. As described above, when the cap 3 is closed, the cap 3 side middle foot 33 is automatically closed with respect to the eccentric outlet port 4 without performing any special positioning operation. be able to.

<Other embodiments>
In addition, this invention is not limited to the said embodiment, Various other embodiments are included. That is, in the above embodiment, the number of combinations of the middle leg portion 33 and the vertical protrusion 51 on the cap 3 side is four, and the number of combinations of the guide step portion 61 and the vertical guide path 62 is four corresponding to this. Is illustrated and described, and one of the vertical guide paths 62 is disposed on the outer peripheral side of the outlet 4. However, the present invention is not limited to this, and the number of combinations is at least one. In addition, the circumferential position setting of the vertical guide path 62 may be other than the above. In short, the circumferential positions relative to the central axis X may be related so that the middle foot portion 33 is fitted into the take-out port 4 when the vertical ridges 51 enter the vertical guide path 62. However, from the viewpoint of smooth rotation guidance of the vertical ridge 51 (or cap 3) by the guide step portion 61, it is preferable that the inclination of the inclined path 612 of the guide step portion 61 is strong. It is preferable to set two or three or more. For example, FIG. 6B shows an example in which three guide step portions 61 ′, 61 ′,... Are formed around the container-side outer peripheral surface 234. The height of the container-side outer peripheral surface 234 (the height of the peripheral wall 233) is shown. If the vertical dimension; the central axis X-direction dimension) are the same, the inclination of each of the ramps 612 'becomes gentler than in the case where the number of combinations in FIG. While there is a possibility of being inferior, the inclination becomes stronger than in the case where the number of combinations is two, and the smoothness is improved accordingly. Furthermore, contrary to the case of the above-described embodiment, the guided convex portion 5 such as the vertical ridge 51 is placed on the container side outer peripheral surface 234 side on the guide step portions 61, 61,..., 61 ′, 61 ′. ,... May be formed on the cap-side inner peripheral surface 321 side.

  In the above embodiment, the container top 23 containing the weighing unit 22 as the container main body 2 is coupled to the storage container unit 21 and the mouth 212 of the storage container unit 21 is closed with the bottom cap 24. The present invention is not limited to this, and the present invention can be applied to any one of an integral type and an assembled type as long as the outlet 4 is provided at an eccentric position with respect to the central axis X on one end face thereof.

  In the above embodiment, the leading end tube 41 is protruded from the top plate portion 231 and the takeout port 4 is configured by the inner space of the leading end tube 41. However, the present invention is not limited to this, and the leading end tube 41 is omitted. ), The through-hole 43 may constitute the outlet 4, and the middle foot 33 may be fitted into the through-hole 43 with the cap 3 closed. Further, as a combination of the take-out port and the fitting foot fitted to this, the take-out port 4 is constituted by the inner hole of the tip tube 41 as in the above embodiment, or the take-out port is constituted by the through hole 43. In such a case, the middle foot portion 33 as a fitting foot portion may be fitted into these take-out ports 4, or the take-out port 4 may be configured by the inner hole of the tip tube 41. In this case, an outer foot portion is formed as a fitting foot portion so as to protrude toward the cap 3, and the outer foot portion is externally fitted from above the distal end tube 41, so that the distal end tube 41 is removed from the upper end opening 42 of the outlet 4. You may make it cover over an outer peripheral surface. Thus, not only the case where the middle foot part is “internally fitted” to the take-out port 4, but also the airtightness can be ensured by “outside fitting” the outer foot part. The outer leg portion is formed by projecting an endless cylinder having an inner diameter corresponding to the outer diameter of the tip cylinder 41 from the inner surface of the cap. Further, as shown in FIG. 10 (b), the guiding means 6 may be formed on the outer peripheral surface below the top plate portion 231 'from which the tip tube 41' protrudes, or in FIG. 10 (c). As shown in the figure, the inclined wall 612a and the groove walls 613a and 613a of the longitudinal guide path 62 may be formed by ribs extending in the radial direction as the mountain-shaped guide path 61a.

  In the above embodiment, the center axis X is arranged in the vertical direction and the take-out port opens in the direction of the center axis X. However, the present invention is not limited to this, and the center axis X opens sideways and the take-out port opens sideways. The present invention is also applied when the cap is closed from the sideways direction. Moreover, in the said embodiment, the extraction port 4 was provided in the upper end surface of the container main body 2, and the cap 3 closed with respect to this upper end surface was shown, However, Not only this but the extraction port is provided in the side surface of the container main body. The present invention is applied not only when the cap is closed with respect to the side surface of the lever, but also when the take-out port, which is the object to be closed by the cap, is provided on the bottom surface. Nor.

  In the above-described embodiment, the mountain-shaped guide path (guide step portion) 61 is shown in which the inclined paths 612 and 612 extend symmetrically on both sides of the apex 611, but the present invention is not limited to this, and is illustrated in FIG. As described above, the slope 612b on one side may extend long across the vertex 611b, and the slope 612c on the other side may be slightly present. In the case of this example, the mountain-shaped guideways 61b having the same shape are arranged in the circumferential direction. For example, the mountain-shaped guideways on both sides in the circumferential direction are arranged symmetrically across the longitudinal guideway 62. Also good. Even if the apex is sharp and it seems that there is no ramp on the other side at first glance, if there is a ramp that can guide the guided convex portion when enlarged, the present invention Corresponds to a mountain taxiway. Further, the “apex” of the mountain-shaped guideway in the present invention does not need to be a sharp point like a cutting edge, or need not be a flat peak. In short, either the cap-side guided convex portion 5 that abuts against the central axis X in the opposite direction acts on the cap 3 when the cap 3 is closed or in addition to the circumferential direction of the mountain-shaped guideway based on gravity. What is necessary is just to perform the function as a so-called water divide so that it can be slid by being distributed to such an inclined road, and the exact shape as a “vertex” is not ask | required.

  In the above-described embodiment, the description has been made with reference to a container with a cap provided with only one as the outlet 4, but the present invention is not limited to this, and the present invention can be applied to a container with a cap provided with two or more outlets. it can. That is, two or more outlets on the end surface on one side in the central axis direction are eccentric positions with respect to the central axis, that is, circumferential positions separated from each other in the circumferential direction along a specific arc R centered on the central axis ( A container body arranged to open at an eccentric position) and a number of fitting feet (medium feet) corresponding to the two or more outlets, and the central axis with respect to the two or more outlets A fitting foot for fitting from the direction to maintain airtightness is provided at each position on the inner surface at each position in the circumferential direction corresponding to the outlet, and an end surface on one side in the central axis direction of the container body is provided. In the closed lid state, the fitting foot is provided in a cap-equipped container including a cap that is fitted to the corresponding outlet, and the fitting foot is provided when the cap is closed. Closed lid with the part fitted to the outlet of the eccentric position A closed guide device cap for positioning by guide induce the cap to reach the. For example, a plurality of outlets such as two, three, four, five, or six may be opened at equal intervals in the circumferential direction on the end surface (for example, the top plate portion 231) on one side in the central axis direction. The cap closing guide device according to the present invention may be applied to the powdered cheese container, various sprinkled containers, etc. Even in this case, the cap can be easily opened by pulling the cap in the central axis direction, while the lid closing operation can be performed simply by covering the central axis direction with rotation guidance and drop guidance in the central axis direction. By the guiding guidance, it is possible to make a closed state in which fitting feet are respectively fitted to a plurality of outlets. Thereby, even if a plurality of outlets are formed, airtightness can be secured by fitting (internal fitting) of the fitting foot (middle foot) with an easy operation.
