Description

TECHNICAL FIELD The present invention relates to a dispensing container that has a rotating part that can be rotated with respect to an exterior body, and that can dispense contents by rotating the rotating part, and in particular, dispenses an intended fixed amount. It relates to an easy dispensing container.

A delivery container is a container configured to push out the contents by means of a screw mechanism, and is conventionally used as a container for solids such as lipstick, solid paste or butter. Examples thereof are described in Patent Documents 1 to 3.

Patent Literature 1 describes the basic structure of a delivery container, and the delivery container includes an exterior body and a guide tube fitted therein so as to be rotatable and retained. , is inserted into the guide tube so as to rotate together with the guide tube and move axially with respect to the guide tube, and is engaged with a female threaded portion formed on the inner surface of the exterior body through the guide tube. and a receptacle. Further, the receptacle is provided with a pedestal on which the contents are placed.

Further, Patent Document 2 discloses a butter case configured to push out butter from the case by providing a rotary push-out knob at the bottom of a cylindrical case containing stick-shaped butter, and rotating the rotary push-out knob. There is another knob which is freely rotatable with respect to the case and which is graduated and is located above and adjacent to the push-out knob. When the start scale of the push-out rotary knob is aligned with the scale of the other knob and the push-out rotary knob is rotated from that position, the amount of rotation of the push-out rotary knob from the scale of the other knob is known, and the rotation of the push-out rotary knob is obtained. Since the amount corresponds to the amount of butter extruded, the amount of butter extruded can be seen from the above scales.

Further, in Patent Document 3, a female threaded member is attached to the lower end of a body cylinder that stores contents, and a threaded rod screwed into the female threaded member is fitted to the outside of the body tube at the bottom end of an operation cylinder. At the upper end of a threaded rod fixed in an upright position to the body tube and extending into the interior of the body tube, there is described a container provided with a receptacle for supporting the contents. By rotating the operation tube, the main tube extends from the operation tube or enters the inside of the main tube by the action of the threaded rod and the female thread member. The outer surface of the main tube is graduated, and the scale aligned with the upper edge of the control tube indicates the amount of content remaining inside the main tube.

Japanese Patent No. 5240837 Japanese Utility Model Laid-Open No. 3-123447 Japanese Utility Model Laid-Open No. 63-194179

In the container described in Patent Document 1, the pedestal portion moves up and down inside the guide tube by relatively rotating the exterior body and the guide tube. It is pushed out of the tube and pulled into the guide tube. However, the amount of extrusion can only be determined by the user's eyes and cannot be known accurately.

On the other hand, in the container described in Patent Document 2, the rotation angle or the amount of rotation of the extrusion knob can be known from the start scale and the scale of the other knobs. Can be quantified and extruded. However, in the configuration of Patent Document 2, first, the scale of the other knob is aligned with the start scale of the push-out knob, the push-out knob is rotated in that state to push out the butter, and the rotation angle or amount of rotation of the push-out knob in that case is adjusted. , is read by the amount of rotation of the scale of the pushing knob relative to the scale of the other knobs. Therefore, in the configuration described in Patent Document 2, it is necessary to first align the scale of the other knob with the start scale of the push-out knob, and it cannot be said that the operability is necessarily good. In addition, in the configuration of Patent Document 2, since the other knob is rotatable, the position of the scale of the other knob only indicates the rotation start position of the push-out knob or the amount of rotation from that position. It cannot be used to indicate the absolute amount or remaining amount of an item. Moreover, the other knobs are parts that are not directly related to containing or pushing out the butter as the content, and are parts that are added only for displaying the amount of pushing out. Therefore, in the configuration described in Patent Document 2, there is a problem that the number of parts increases.

Furthermore, the container described in Patent Document 3 supports the contents on a receptacle provided at the tip of a threaded rod integrated with the operation cylinder, and rotates the main body cylinder and the operation cylinder relative to each other. The container is constructed such that the cylinder is drawn into the operation cylinder, thereby causing the contents to protrude relatively toward the tip side of the main cylinder. That is, the amount of penetration of the main tube into the operation tube is the amount of protrusion (extension amount) of the contents. Since the scale attached to the outer surface of the main tube functions to display the amount of penetration of the main tube into the operation tube in this way, the pushing amount (extending amount) of the contents can be known. However, a container as described in Patent Document 1, that is, a container having a configuration in which the contents protrude from a guide tube and the guide tube does not move in the axial direction with respect to the exterior body, so that the total length does not change , the configuration for display described in Patent Document 3 cannot be applied. Furthermore, in the configuration described in Patent Document 3, all the scales from 0% to 100% appear on the outer surface of the container, so depending on the contents, there is a possibility of design restrictions or defects.

The present invention has been made by paying attention to the above technical problem, and is a container configured to push out the contents, which can control the amount of pushing out and the remaining amount without increasing the number of parts and design. To provide a feeding container which can be displayed without impairing the quality and is excellent in operability.

In order to achieve the above objects, the present invention provides a cylindrical body case having a spiral groove formed on its inner peripheral surface, and a cylindrical body case inserted into the body case so as to be rotatable and axially immovable. a guide sleeve having one end extending from the body case in the axial direction; and a guide portion formed along the axial direction of the peripheral wall portion of the guide sleeve, and a guide portion held inside the guide sleeve so as to move back and forth in the axial direction of the guide sleeve, A fixed-quantity dispensing container having a lifter sleeve that holds the contents at one end, that is, an upper end, and an engaging projection that protrudes from the lifter sleeve through the guide portion and engages with the spiral groove, Either the lifter sleeve or the guide sleeve is provided with an information display section for displaying the amount of movement of the lifter sleeve, which rotates relative to the body case together with the guide sleeve and moves in the axial direction, and the information The body case is provided with a display portion that exposes the marking portion to the outside of the body case so as to be visually recognizable. The body case has a center ring that fits the guide sleeve on the inner peripheral side and prevents the guide sleeve from slipping out from the body case. A downwardly open, cylindrical elastic inner peripheral skirt portion is integrally provided on the inner peripheral side of the center ring and at a location opposed to the first click tooth, On the inner peripheral surface of the peripheral skirt portion, a plurality of second click teeth having the same length in the axial direction as the inner peripheral skirt portion and elastically meshing with and disengaging from the first click teeth are formed on the inner peripheral skirt portion. It is characterized in that they are provided at regular intervals in the circumferential direction of the peripheral skirt portion .

In this invention, the information writing portion is provided on the outer peripheral surface of the lifter sleeve, and the display portion matches the information writing portion of the body case in the axial direction and in the radial direction perpendicular to the axial direction. A window hole provided at a position, and the guide sleeve may be provided with a translucent part at a position coinciding with the information writing part and the window hole in the axial direction and the radial direction.

In this invention, the information writing portion is spirally formed on the outer peripheral surface of the lifter sleeve so as to coincide with the window hole in the axial direction and the radial direction when the lifter sleeve rotates and moves in the axial direction. The translucent portion may be configured by either a penetrating portion or a transparent portion provided in the guide sleeve.

In the present invention, the click teeth are disengaged when the guide sleeve rotates forward relative to the body case so that the lifter sleeve moves toward the opening end of the guide sleeve, and The ratchet teeth may be provided so that the engagement is not disengaged in the negative rotation direction opposite to the positive rotation.

In this aspect of the invention, the lifter sleeve has a piston at the upper end thereof, the piston and the guide sleeve form a storage chamber for storing the contents, and the outer peripheral portion of the piston defines the storage chamber. A lip seal piece may be provided, the force of which is increased against the inner circumferential surface of the guide sleeve with increasing pressure.

The present invention further includes a cap that covers a portion of the guide sleeve extending from the body case, and the cap is fitted to the center ring to hide the window hole from the outside. It can be.
Further, in the present invention, the information notation portion may include a plurality of numbers arranged at the same intervals as the intervals between the first click teeth and the intervals between the second click teeth.

In the fixed-quantity delivery container according to the present invention, when the body case and the guide sleeve are rotated relatively, the lifter sleeve is attached to the body case together with the guide sleeve because the engaging protrusions are engaged with the guide portions of the guide sleeve. rotate against. In addition, since the engaging protrusion is engaged with the spiral groove provided on the inner peripheral surface of the body case, the lifter sleeve moves in the axial direction of the body case, and the lifter sleeve moves the contents to the tip of the guide sleeve. sent out from the department. The amount of delivery of the contents (the amount of movement of the lifter sleeve) is determined by the lead angle of the spiral groove and the rotation angle of the relative rotation. An information display for displaying the amount of movement is provided on either the guide sleeve or the lifter sleeve. It is exposed to the outside through a display section provided in the container, and the amount of delivery of the contents can be known from the information content. Therefore, according to the present invention, the delivery amount of the contents can be used without adding new members to the body case, the guide sleeve, and the lifter sleeve, which are basic components for accommodating and delivering the contents. It is possible to inform the operator or the user, simplify the configuration of the so-called quantitative dispensing container, and reduce the cost.

In addition, in the present invention, since the information content that can be known through the display section is the amount of movement of the lifter sleeve, it is possible not only to know the amount of the content to be fed out, but also to know the remaining amount of the content. can know.

Furthermore, according to the present invention, the body case can have a ring portion, and by providing a window hole in the ring portion, it is possible to reduce the influence or restriction on the design of the feeding container as a whole. In particular, a cap that covers the tip side portion of the guide sleeve can be fitted to the ring portion to close the window hole. .

On the other hand, in the present invention, each time the click teeth engage with each other, the operation of relatively rotating the guide sleeve and the body case is temporarily stopped, that is, a click feeling is obtained. You can easily pull things out.

In particular, if the click tooth is configured as a ratchet tooth that prevents reverse rotation, the remaining amount of the contents can be known through the display section.

In the present invention, by providing the piston, it is possible to form the storage chamber isolated from the outside, so that the storage chamber can store high-viscosity fluid contents. In that case, when the contents are fed out (extruded) by the lifter sleeve, the pressure in the storage chamber increases, and accordingly the lip seal piece is strongly pressed against the inner surface of the guide sleeve. It can be a delivery container that does not leak.

Specific examples of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of a metered delivery container (hereinafter sometimes simply referred to as container) 1 according to the present invention. A sleeve 3 and a lifter sleeve 4 are provided.

The body case 2 forms a so-called exterior body for the container 1 as a whole, and has a cylindrical shape with a bottom, and a spiral groove (screw groove) 5 is formed on the inner peripheral surface. The spiral groove 5 constitutes a part of a screw mechanism for moving the lifter sleeve 4 in its axial direction (vertical direction in FIG. 1), and it is common to rotate it clockwise when feeding out the contents. , are preferably right-handed threads. Moreover, it may be a multiple thread groove such as two threads.

An example of a guide sleeve 3 is shown in FIG. The guide sleeve 3 is a cylindrical member, the lower half of which is inserted into the body case 2 and is in close contact with the inner surface of the body case 2, and the upper half of which extends from the body case 2 upward ( upward in FIG. 1). In the following description, substantially the lower half portion of the guide sleeve 3 inserted into the body case 2 is referred to as an insertion portion 3A, and substantially the upper half portion extending out from the body case 2 is referred to as an extension portion 3B. Write down. A guide portion 6 is formed in the insertion portion 3A of the guide sleeve 3 . The guide portion 6 is a slit-shaped portion formed linearly upward from the lower end portion of the guide sleeve 3, and is formed so as to penetrate the peripheral wall portion of the guide sleeve 3 in the plate thickness direction. The guide portion 6 is for applying torque to the lifter sleeve 4 inserted therein. , is preferably formed linearly along the axial direction, but the present invention does not exclude a slight inclination with respect to the axial direction. Further, the guide portion 6 is formed in substantially the same range in the axial direction as the range in which the spiral groove 5 of the body case 2 is formed. Moreover, the guide portion 6 is not limited to being formed at one place in the circumferential direction of the guide sleeve 3, but is preferably formed at, for example, two places facing each other in the radial direction.

A convex portion 7 is formed on a portion of the outer peripheral surface of the guide sleeve 3 above the guide portion 6 , more specifically, on a portion corresponding to the upper edge of the body case 2 . The convex portion 7 is a portion for retaining the guide sleeve 3 from the body case 2 , and is a flange-like or bead-like portion projecting from the outer peripheral side of the guide sleeve 3 . A plurality of first click teeth 8 are formed on the upper side of the convex portion 7 at regular intervals in the circumferential direction. In the example shown in FIG. 2, these first click teeth 8 are recesses with arcuate cross-sections formed in the axial direction, as shown enlarged in FIG.

The lifter sleeve 4 is a cylindrical member that moves in the axial direction (vertical direction in FIG. 1) inside the guide sleeve 3 in close contact with the inner peripheral surface of the guide sleeve 3. ) is formed with an engaging projection 9 that penetrates the guide portion 6 and extends to the spiral groove 5 and engages with the spiral groove 5 . Therefore, when the guide sleeve 3 is rotated with respect to the body case 2, the engaging protrusions 9 are engaged with the guide portion 6 of the guide sleeve 3 in the rotational direction (circumferential direction). It rotates together with the guide sleeve 3. In this case, since the engaging protrusion 9 is engaged with the spiral groove 5 and moves along the spiral groove 5, the lifter sleeve 4 moves in the axial direction while rotating. That is, the engaging protrusion 9 and the spiral groove 5 constitute a screw mechanism.

The lifter sleeve 4 is a member for holding the content inside the container 1 and pushing it out from the container 1, and a piston 10 is provided at the other end (upper end). The piston 10 closes the upper end of the cylindrical lifter sleeve 4 and forms an accommodation chamber 11 together with the extension 3B of the guide sleeve 3 described above. As shown in FIG. 1, the piston 10 has a disk portion 10A at the upper end and a cylindrical skirt portion 10B integrally formed on the outer periphery thereof. The piston 10 is attached to the lifter sleeve 4 by inserting the portion 10B into the attachment groove 4A formed along the entire circumference of the upper end of the lifter sleeve 4 . As shown in FIG. 4, a ridge 12 is formed over the entire circumference of either the skirt portion 10B or the mounting groove 4A, and a concave groove 13 is formed in the other to which the ridge 12 is fitted. The ridges 12 and the grooves 13 integrate the piston 10 with the lifter sleeve 4 so that the piston 10 does not come off.

Furthermore, a lip seal piece portion 14 is provided on the outer peripheral portion of the piston 10 . This lip seal piece 14 is for ensuring the airtightness of the housing chamber 11, and as shown in FIG. be. The lip seal piece 14 is formed to be elastic and thin, and the tip is in close contact with the inner peripheral surface of the guide sleeve 3 . Since it is open obliquely upward, it is configured to be pressed against the inner peripheral surface of the guide sleeve 3 by the pressure inside the storage chamber 11 . Therefore, when the piston 10 moves upward in FIG. 1 so as to push out the contents, the pressure inside the storage chamber increases, so that the lip seal piece 14 moves toward the inner circumference of the storage chamber 11 according to the increase in pressure. It is strongly pressed against the surface, and as a result, the sealing property (hermeticity) of the housing chamber 11 is improved.

The body case 2 has a center ring 15 at its upper end. The center ring 15 has the original function of preventing the guide sleeve 3 from coming off from the body case 2, and also has other functions as described below. An example of a centering ring 15 is shown in FIGS. 5-8. The center ring 15 shown here is a cylindrical member having an outer diameter approximately equal to the inner diameter of the body case 2 and a short axial length. A protruding portion 15B having an outer diameter equal to the outer diameter of the body case 2 is formed over the entire circumference in a portion adjacent to the upper side of the fitting portion 15A. The center ring 15 is fitted to the body case 2 while the protruding portion 15B abuts against the upper end of the body case 2. As shown in FIG. The fitting portion 15A and the inner peripheral portion of the upper end of the body case 2 are provided with a fitting structure similar to the projection 12 and the groove 13 shown in FIG. 15 and the body case 2 are firmly integrated. In this state, the lower end of the fitting portion 15A abuts against the convex portion 7 of the guide sleeve 3 described above, and as a result, the guide sleeve 3 is retained from the body case 2. As shown in FIG.

An inner peripheral skirt portion having approximately the same length as the first click tooth 8 (length in the axial direction) is provided at a portion of the inner peripheral portion of the center ring 15 facing the first click tooth 8 of the guide sleeve 3 described above. 15C is integrally provided. The inner peripheral skirt portion 15C is a thin cylindrical portion that opens downward, and a plurality of second click teeth 16 are formed on the inner peripheral surface thereof. The second click tooth 16 is an engaging tooth that elastically meshes with the first click tooth 8 described above, and as shown in FIGS. . The interval (pitch) of each second click tooth 16 matches that of the first click tooth 8 . Also, the cross-sectional shape of the second click tooth 16 is a convex circular arc so as to correspond to the cross-sectional shape of the first click tooth 8 . Furthermore, a slit (cut) may be provided between each of the second click teeth 16 so that each of the second click teeth 16 can be elastically bent independently. Therefore, when the guide sleeve 3 is forcibly rotated with respect to the body case 2 (center ring 15), the first click tooth 8 and the second click tooth 16 are disengaged from each other, and the circumferences of both are disengaged. Since the positions in the directions are substantially the same, the elastic force of the inner peripheral skirt portion 15C or the elastic force of the click teeth 8 and 16 rapidly mesh with each other. That is, the sudden engagement causes a change in the torque for rotating the guide sleeve 3 with respect to the body case 2, and the change in torque is configured to give a click feeling (moderation feeling). The number of teeth and spacing (pitch) between the first click teeth 8 and the second click teeth 16 do not necessarily have to be the same. It is also possible to widen the interval (pitch) by making the number of teeth of one of the first click teeth 8 and the second click teeth 16 smaller than the number of teeth of the other. In this way, by reducing the number of teeth and widening the interval (pitch), the number of teeth that mesh during rotation is reduced, and the force required for rotation is reduced, so that rotation can be easily performed.

A window hole 17 is formed at a predetermined position in the circumferential direction of the upper end of the center ring 15 . The window hole 17 is a portion for making the inside of the center ring 15 visible from the outside, and corresponds to the display portion or the window hole in the present invention. In the example shown in FIGS. 5 to 7, the window hole 17 is a rectangular notch extending through the center ring 15 from inside to outside.

As described above, the lifter sleeve 4 for pushing out the contents moves in the axial direction while rotating. This is where we are. An information indicating portion 18 indicating the amount of movement of the lifter sleeve 4 or the amount of delivery of the contents is provided at such a spiral portion. An example is shown in FIG. The example shown in FIG. 9 is an example of numbers, and it is preferable that the intervals between the numbers match the pitches of the click teeth 8 and 16 described above. Among these numbers, the topmost number is attached to the outer peripheral surface of the lifter sleeve 4 so as to match the window hole 17 when the lifter sleeve 4 is in the lowest position. "1" means first. When such a number string is provided in the information display section 18, those numbers also represent the number of clicks (number of clicks) by the click teeth 8 and 16. It is possible to know the used amount or remaining amount of the battery.

Since the information display portion 18 is positioned on the inner peripheral side of the guide sleeve 3, the guide sleeve 3 has a A translucent portion (not shown) is provided. This translucent part is simply configured so that the information writing part 18 provided on the lifter sleeve 4 can be visually observed through the window hole 17 . For example, when the guide sleeve 3 and the lifter sleeve 4 are configured to rotate one turn (360°) or more to feed out the entire contents, a transparent portion covering the entire circumference at a position corresponding to the window hole 17 can be a light transmitting portion, or the entire guide sleeve 3 can be made of a transparent material and the whole can be a light transmitting portion. Further, a plurality of penetrating portions having the same shape as the window holes 17 and formed in the peripheral wall portion of the guide sleeve 3 at the same pitch as the numerals may be used as the translucent portions. Furthermore, in the case where the entire content can be drawn out without rotating the guide sleeve 3 once, the translucent portion is formed on the peripheral wall portion of the guide sleeve 3 along the circumferential direction. It may be a slit-shaped penetrating portion.

In FIG. 1, reference numeral 19 denotes a nozzle member. The nozzle member 19 is a member for molding the contents into a predetermined shape, such as a shaft shape or a linear shape, and extruding the shape, and is fitted to the outer peripheral side of the extension portion 3B of the guide sleeve 3 . The nozzle member 19 has a nozzle formed integrally with the top plate portion and a cylindrical portion formed on the outer peripheral portion of the top plate portion to extend in a direction opposite to the nozzle. It is attached to the guide sleeve 3 by fitting it to the projecting portion 3B. The structure for fixing the cylindrical portion to the extending portion 3B may be a fitting structure similar to the protrusion 12 and the groove 13 shown in FIG. 4 described above. Accordingly, the upper end portion of the storage chamber 11 is closed by the nozzle member 19, and the nozzle provided on the top plate portion of the nozzle member 19 serves as a discharge port.

Further, reference numeral 20 in FIG. 1 indicates a cap. The cap 20 is configured to cover the extending portion 3B of the guide sleeve 3 for protection against dust and protection, and is integrated with the top plate portion covering the upper side of the nozzle member 19 and the outer peripheral portion of the top plate portion. and a cylindrical portion that is fused. The cylindrical portion has a shape obtained by extending the body case 2 described above and has the same outer diameter as the body case 2 . The inner diameter of the opening end (lower end) side of the cylindrical portion is set to an inner diameter that is closely fitted to the outer diameter of the upper end portion of the center ring 15 described above. That is, the cap 20 is fitted to the center ring 15 and integrated with the body case 2 , and in this state covers the portion extending from the body case 2 such as the nozzle member 19 . Therefore, when the cap 20 is attached to the body case 2, the window hole 17 corresponding to the display section in the present invention is covered by the cap 20. As shown in FIG. Therefore, it is avoided that the window hole 17 and the information writing part 18 which can be seen from here become a hindrance factor or a restriction factor of the design of the container 1 .

In the above-described container 1 according to the present invention, when the body case 2 and the guide sleeve 3 extending from the body case 2 are gripped and rotated counterclockwise relative to each other, the lifter sleeve 4 moves into the spiral groove 5 and the spiral groove 5. It moves to the bottom side of the body case 2 by a screw mechanism consisting of the engaging projection 9 engaged with the body case 2 . Alternatively, the lifter sleeve 4 is retracted (lowered) to the bottom of the body case 2 and both are assembled. In this state, an appropriate high-viscosity content is put into the storage chamber 11 , and then the nozzle member 19 is fitted to the extension portion 3</b>B of the guide sleeve 3 . If the content is a solid substance such as lipstick or glue stick, the storage chamber 11 may only be filled with the content, and the nozzle member 19 may not be attached to the extension portion 3B of the guide sleeve 3. This state is the initial state or the state before shipment, and the initial value or initial display in the information display section 18 appears at the position corresponding to the window hole 17 . The window hole 17 and the information indicating portion 18 are hidden by the cap 20 by fitting the cap 20 over the extension portion 3B of the guide sleeve 3 and fitting it to the center ring 15 so that they do not appear outside the container 1 .

When the cap 20 is removed and the guide sleeve 3 and the body case 2 are rotated clockwise relative to each other, the lifter sleeve 4 is engaged with the guide sleeve 3 by the action of the screw mechanism consisting of the guide portion 6 and the engaging protrusions 9 . The inside is pushed upward in the axial direction. That is, the contents inside the storage chamber 11 are pushed by the piston 10 and pushed out from the discharge port of the nozzle member 19 . When the relative rotation angle between the guide sleeve 3 and the body case 2 reaches a rotation angle corresponding to one pitch (one tooth) of the click teeth 8 and 16 described above, the click teeth 8 and 16 mesh again by elastic force, and a click feeling is generated. occurs. In this way, one pitch of content is extruded. At the same time, since the lifter sleeve 4 rotates and rises to make a so-called helical motion, the second content of the information writing section 18 written in a helical shape appears in the window hole 17 and can be visually observed through the window hole 17. The available information content switches to content representing the amount for one pitch. It is also possible to rotate the guide sleeve 3 to push out a desired amount of content while viewing the information content visible through the window 17 . In any case, it is possible to push out (feed out) a fixed amount of contents intended by the consumer (user). In addition, since the information content corresponds to the position of the lifter sleeve 4 in the axial direction, it is possible to know the remaining amount of the content from the information content.

As described above, in the container 1 according to the present invention, the body case 2, the guide sleeve 3, and the lifter sleeve 4, which are basic constituent members for containing and feeding the contents, are partially processed. , the intended amount of contents can be delivered and the remaining amount can be known. Therefore, according to the container 1 of the present invention, there is no member added for quantifying the amount of extrusion, so that the overall structure can be simplified and the cost can be reduced.

If the guide sleeve 3 and the body case 2 are rotated only in the direction in which the contents can be delivered (positive rotation direction), the change in the information content visible through the window hole 17 will always cause the contents to be delivered. match the capacity. A ratchet mechanism for that purpose will be described. 10 to 12 show examples in which ratchet teeth 8A and 16A are formed on guide sleeve 3 and center ring 15. FIG. As shown in FIG. 10, the guide sleeve 3 is provided with a first ratchet tooth 8A instead of the first click tooth 8 described above, and the center ring 15 is provided with a second ratchet tooth 8A instead of the second click tooth 16 described above. Ratchet teeth 16A are provided. When the rotation direction in which the guide sleeve 3 and the body case 2 are rotated relative to each other so as to lift the lifter sleeve 4 is defined as the forward rotation direction, the first ratchet teeth 8A are arranged in the forward rotation direction of the guide sleeve 3 with respect to the body case 2. This is an engagement tooth in which the front side tooth flank is gently slanted with respect to the circumferential direction, and the opposite tooth flank is a steeply slanted tooth flank with respect to the circumferential direction. be. On the other hand, the second ratchet tooth 16A is an engagement tooth having a shape symmetrical to the first ratchet tooth 8A, and the tooth surface on the front side in the forward rotation direction with respect to the guide sleeve 3 of the body case 2 is circumferentially oriented. It is an engaging tooth that has a gently slanted tooth flank with respect to the circumferential direction and a steeply slanted tooth flank that rises with respect to the circumferential direction on the opposite side.

Therefore, when the body case 2 (center ring 15) and the guide sleeve 3 are relatively rotated in the forward rotation direction, the ratchet teeth 8A and 16A come into contact with each other on the gently sloping tooth surfaces as shown in FIG. At least one of the ratchet teeth 8A, 16A is elastically bent in the radial direction of the body case 2 or the guide sleeve 3, and these ratchet teeth 8A, 16A are disengaged. That is, the body case 2 (center ring 15) and the guide sleeve 3 can be rotated forward relative to each other to let out (extrude) the contents. When a torque is applied to rotate the body case 2 (center ring 15) and the guide sleeve 3 in the negative rotation direction opposite to the positive rotation direction, the steeply inclined tooth flanks of the ratchet teeth 8A and 16A move toward each other. Since they abut, the ratchet teeth 8A and 16A are not disengaged, and therefore the body case 2 (center ring 15) and the guide sleeve 3 cannot be rotated in the relative negative rotation direction. Since the rotation in the negative rotation direction is the rotation in the direction of lowering (pulling) the lifter sleeve 4 into the inside of the body case 2, if the above-described ratchet mechanism is provided, the contents can be fed out, but the guide It cannot be pulled back inside the sleeve 3.

When the ratchet mechanism is provided as described above, the lifter sleeve 4 or the piston 10 is not pulled back, and the storage chamber 11 is always filled with the contents without causing a space inside the storage chamber 11. will be fulfilled. Therefore, the information content visible through the window hole 17 matches the remaining amount of the content. Further, since the direction in which the guide sleeve 3 and the body case 2 can be rotated is limited to the forward rotation direction, if the guide sleeve 3 and the body case 2 are rotated relative to each other, the amount of content corresponding to the rotation angle can be changed. you can pull things out. In that case, the ratchet teeth 8A and 16A give a so-called click feeling (tightness), so that the content can be fed out by a fixed amount corresponding to one pitch.

After drawing out and consuming the necessary amount of contents, the cap 20 is put on the extension 3B of the guide sleeve 3 and fitted to the center ring 15. - 特許庁By doing so, the protruding opening of the nozzle member 19 is covered by the cap 20, and is protected from intrusion of dust and damage due to external force. In addition, since the window hole 17 is covered by the cap 20 , the window hole 17 does not hinder or restrict the design of the container 1 .

In the metered delivery container according to the present invention, as explained based on the above specific example, the guide sleeve 3 only rotates relative to the body case 2 and does not move in its axial direction. The relative rotation angle matches the delivery amount (extrusion amount) of the contents. Therefore, in the present invention, the information writing portion may be provided on the outer peripheral surface of the guide sleeve, and the reference mark as the display portion may be provided on the body case. Specifically, a reference mark is provided at a predetermined position on the upper edge of the center ring 15 described above, and an information marking portion is provided at a position on the circumference along the upper edge of the center ring 15 on the outer peripheral surface of the guide sleeve 3. It is also possible to provide a suitable scale as a reference mark so that the extension amount is indicated by the scale that coincides with the reference mark.

In addition, the information content of the information notation part in the present invention does not have to be numerical, and may be displayed in a manner similar to a bar graph representing the amount by length, in numbers such as dots or star marks, or in addition to these, with the addition of colors. Any display that can be visually grasped, such as a display that

Although the present invention has been described above with reference to specific examples, the present invention is not limited to the above-described specific examples, and may be appropriately modified within the scope of the matters described in the claims.
