Description

CONTAINER TO SEE AND APPLY A CONSTANT AMOUNT OF A LIQUID TECHNICAL FIELD The present invention relates to a recipient for liquids, such as a medicinal tonic for hair growth, which is expensive and its amount poured and used in an operation is made constant, more particularly, to a container in the which a quantity of liquid poured in a pouring / application operation automatically measures up to a certain amount.

BACKGROUND OF THE INVENTION As a pouring and application sealant, use in this class of containers, which pour and apply a constant amount, the Applicant has already proposed an invention, according to the patent JP-U-6-35153. In this prior art, a combination of a change unit and an operation unit, which form a measuring chamber and has an open / close valve unit assembled in a pouring nozzle and which isolates the measuring chamber from a measuring unit. bottle by a firm contact of the exchange unit against an external flange d sealed, in an ascending limit, joins, vertically, firmly, in a displaceable way, to a fixing unit, which is attached, in a firm and immobile way, the bottle unit and is provided with a sealing unit, which has the external sealing flange and an upper sealing surface. In a usable state, only a quantity of the liquid, which has been measured, will be an adequate quantity that can be poured and the pouring of liquid which is wasted is prevented. The change unit is attached to the fixing unit in a vertically movable manner, by placing a threaded pipe inside the threaded coupling, with a tube attached, inseparably to the fixing unit, by the fact that an adjacent flange of the unit of change rests against a retaining flange of the fixing unit, from the lower side in the ascending limit. At the downward limit of the change unit, a lower surface of a valve seat of a valve unit is brought into contact with the upper sealing surface of the holding unit, and thus prevents the downward movement of the unit. d valve by the holding unit in the unused state of the container. Therefore, even when an abnormal pressure is exerted on the upper end of a valve head, which projects from the spout, this valve unit does not open, and the closed state of the bottle unit remains. In the prior art, described above, the opening / closing valve unit is structured as follows. The valve head is mounted in the pouring mouth of the operation unit, so that it can move vertically and be able to project from the mouth, it is provided with vertical grooves cut on the outer circumference surface. A valve seat, which can come into close contact with a lower periphery of the pouring spout of the operation unit, and provided at the lower end of the valve head. A plurality of helical elastic elements, which provide an ascending elastic force, are connected to the valve seat at their upper ends and to the change unit at their lower ends. - Therefore, the closing opening valve unit is assembled in such a way that approximately the portion of the lower half of each elastic element is located inside the measuring chamber, under the compressed condition, in order to supply an ascending elastic force , that is, under the condition that each elastic element is compressed vertically and deform elastically. Because part of the capacity of the measuring chamber is occupied by the plurality of elastic elements, the actual capacity of the measuring chamber is varied by a slight change in the shape of an elastic deformation of these elastic elements. Accordingly, there is the problem that it is difficult to correctly match a quantity of the liquid actually measured with a predetermined amount. When the change unit is assembled to the fixing unit, a stop flange, disposed around the lower end of the surface of the internal circumference of the change unit, must be forcibly passed over a helical flange and a retaining flange on a surface of the outer circumference of an attached pipe, which it is going to be threaded with the fixing unit. Therefore, there is a fear that the flanges, described above, may be deformed. Furthermore, there is a problem that, if the height of the stop flange becomes low, in order to prevent the occurrence of deformation, a function preventing the escape of the stop flange becomes possibly insufficient. There is another problem that it is impossible to increase the sensation of use by the provision, in a portion of the stop flange of the change unit, of a thin piece that produces a sound, which, in the ascending descending limits of the unit of change , it goes over a vertical rebord _ provided on the surface of the outer circumference of the fixing unit, to generate a "click" sound (light blow). This is because there is a great possibility that the piece producing the sound will be broken when it goes over the helical flange and the retaining flange at the junction of the change unit to the fixing unit. There is still another problem. If the threaded coupling of the shifting unit to the clamping unit s squeezes, turning the operating unit excessively, the valve seat of the valve unit, which goes down together with the shifting unit and the operating unit, s sandwich strongly between a lower edge of the pouring spout of the operating unit and the upper sealing surface of the sealing unit. In that case, there is fear that the valve seat may be deformed or some other damage, and may lose its sealing function. Also, it is not regulated so that a position of attachment of the application obturator with respect to the bottle unit in the circumferential direction becomes constant. Therefore, even if a display of the opening / closing position can be marked on the application shutter, for convenience of operation, it is almost impossible to place exactly the display co with respect to the bottle unit. Therefore, there is a problem that it is not possible to effectively place the pre-marked display of the opening / closing position on. That is, when a front / back relationship is given to a disposition of the bottle unit, displaying a merchandise name on one side and using addresses on the other side of the bottle unit, there is a need to adapt display positions on the shutter d application, such as the display of the opening / closing position d or a display of the action position, to the front / rear position relation of the bottle unit, for the convenience of handling and for the display function effective However, unless the positional relationship in the circumferential direction between the bottle unit and the application shutter is controlled, in order to take a fixed position, it is impossible to adapt the displays made in the application shutter to the ratio of front / rear position of the bottle unit. Thus, the invention was carried out to solve these problems encountered in the prior art, described above. A technical subject of the present invention is to overcome any change in the capacity of the measuring chamber, which could be caused by the change in the shape of the elastic deformation of the opening / closing valve unit, and so on. An object of the invention is to always make it possible for the liquid contained in the bottle unit to be measured and poured with precision. Another technical subject of the present invention is that the assembly of the change unit to the fixing unit is achieved naturally, safely and firmly, thus, an object of the present invention is easily obtained a stable assembly and signature and also Favorable detection for use. Still another technical matter of the present invention, is to fix the circumferential position of attachment of the application seal with respect to the bottle unit in a fixed position, and thus an object of the invention is to make effective use of the displays in the application shutter and obtain the correct handling and favorable, of the recipient.

EXHIBITION OF THE INVENTION The invention, according to claim 1, comprises: a bottle unit, having a boc tube in its upper part; an application shutter, which includes: a fixing unit, which is attached, firmly and immovably, to the mouth tube of the bottle unit is provided with a shutter unit, which has an external sealing flange in a open upper end d a central portion; a change unit, which is mounted, firmly and vertically, in a displaceable manner, on the fixing unit, is provided with an internal tube placed in the central portion, so that the external sealing flange fits closely into an opening of the upper end in an ascending limit for the unit of change; an operation unit of a cylindrical configuration, having an upper plate, which is mounted, narrowly and immovably, on the change unit, and is provided with a pouring spout at its upper end, this operating unit defines a chamber measuring a certain volume, together with the unit of change; and a valve unit, which is provided with a valve head mounted within the spout, such that its upper end portion can project from the spout, and a valve seat provided around the lower end of the spout. valve head and which comes in close contact with the opening portion of the lower end of the spout, this valve unit supplies an elastic force rising to an integrated member of the valve seat and the valve head; and a cap unit, which covers the applicator plug and removably mounted on an upper end of a barrel portion of the bottle unit, - in which the valve unit further comprises a plurality of plates fastening placed on the upper surface of a fixing ring and is attached, immobile, to the change unit, and a plurality of helical elastic elements, which interconnect the fixing plates and the valve seat, these fixing plates have a height substantially equal to the depth of the measuring chamber. In an unused state, that is, in the measurement state, in which a combination of the change unit and the valve unit and the operating unit are located at a downward limit, the spout of the unit Operation is closed by the valve unit. At the same time, the external sealing flange of the shutter unit of the fixing unit is placed above the inner tube of the change unit, and a gap is formed between the external sealing flange and the inner tube. Accordingly, the measuring chamber, formed between the change unit and the operating unit, is in communication with the interior of the bottle unit. To empty and apply a constant amount of liquid contained from this state, first, the bottle unit is turned with the upper side down, to allow the liquid to flow from the bottle unit to the measuring chamber, and then this unit of bottle is returned to the erect position, to allow a constant amount of liquid to remain in the measuring chamber. Next, the operation unit is operated to move the combination of the change unit, the valve unit and the operation unit upwards to the rising limit, relative to a combination of the fixing unit and the shutter unit. Due to this upward displacement, the external sealing flange of the obturator unit is firmly mounted in the upper opening of the internal tube of the change unit. As a result, the measuring chamber is disconnected from inside the bottle unit, and the container becomes in the usable state, which allows the application of the liquid.

Once the application shutter is in the application state, the bottle unit is turned with the upper side down, and the valve head, projected from the spout of the operation unit, is pressed down on a surface to be applied, such as the skin of the bottle. the human head When the valve head is pressed against the surface to be applied, it is pushed into the spout and this mouth opens. The constant amount of liquid in the measuring chamber is discharged and applied to the surface. During the application of the liquid to the surface, no liquid drains out of the bottle unit, because this bottle unit is in the closed state, since the external sealing flange is firmly mounted in the upper opening of the inner tube of the bottle. change unit. That is, only a constant amount of the liquid that has been measured inside the measuring chamber was applied on the surface. After the application of the liquid is complete, the bottle unit is detached from the surface, and restored to its upright position, and the combination of the change unit, the valve unit and the operation unit is brought back to the limit falling. With the separation of the container from the surface, the valve head returns to its original position by means of the elastic force from the elastic elements, so that the spout is closed. As the combination of the change unit, valve unit and operating unit goes back to the descending limit, the connection between the measuring chamber and the inside of the bottle unit is restored, and the vessel returns to the measurement state. The helical spring elements of the valve unit are fixed to the upper ends of the fixing plates set at a height substantially equal to the depth of the measuring chamber. Therefore, these elastic elements are not located in the measuring chamber, so there is little possibility that they affect the capacity of the measuring chamber. Thus, the precise specified quantity of the liquid can always be measured and applied.

In the process of assembling the container for the pouring and the application of a constant amount of liquid, according to the invention, the change unit is mounted smoothly on the fixing unit, without the convex portions adjoining the pieces reaching the contact with the retaining flange or helical flange of the fixing unit, because the plurality of parts preventing leakage on the lower periphery of the change unit, are connected in the extended state. Next, the operating unit is pushed, forcedly, on the change unit, so that each of the parts preventing the escape bend in the thin portions and are pushed into the interior by a lower end surface of the unit of operation. In that state, the change unit can be inhibited to move away from the fixing unit.

These pieces that prevent the escape and the piece that produces the sound, are folded inside, when the unit of operation mounts on the unit of change. The surmountable convex portion and the flange that produces the click are allowed to go over the vertical flanges on an outer circumference of the fixing unit, to result in a clicking sound and to provide the detection of the click just before the ascending limit and the limit descending of the unit of change. In the inventions, according to claims 3 and 4, the change unit is mounted smoothly on the fixing unit, without the plurality of parts preventing the escape and the pieces that produce sound coming into contact with the retaining flange or the helical flange of the fixing unit, because the plurality of parts preventing leakage and the sound producing part in the lower periphery of the change unit are connected in the extended state.

In a state in which the change unit has been mounted on the fixing unit, when the operating unit is mounted, forcedly, on the change unit, the parts that prevent the escape and the sound producing part folded into respective thin portions are pushed inside. In that state, the change unit can be inhibited from escaping from the fixing unit.

THE BEST WAY TO CARRY OUT THE INVENTION The embodiments of the invention will be described with reference to the drawings. Figure 1 shows a full vertical cross-sectional view, in which an application plug 1 is attached to the mouth tube 80 of a bottle unit 8. In Figure 1, the right half indicates an unused state and a measurement status of a container for pouring and applying a constant amount of liquid, and the left half indicates a state that can be used and an application status . The mouth tube 80 (see Figure 3) of the bottle unit 8, to which the application plug 1 is attached, is provided with a circumferential retention flange 81, provided on a central part of an external circumference surface of the mouth tube, a vertical retention flange 82, disposed in an upper area of the outer circumferential surface, a circumferential rim 86 arranged in parallel with the circumferential retention flange 81 and connected to the vertical retention flange 82 at one end and forming at the other end a vacant zone 87 together with the vertical retention flange 82, an outer flange 83 is provided in a lower portion of the outer circumferential surface, and a pair of projections 84 are formed in the opposite diametrical positions on an upper surface of the outer flange 83. A pair of coupling cavities 85 are formed on both sides of an upper portion of a barrel, whose section is substantially elliptical. A fixing unit 2 is provided with a flange tube, the diameter of which is enlarged at a lower end. A helical flange 23 (in the case of a mode shown in Figures 4, 5 and 6) or a guide groove 23b (in the case of a modality shown in Figures 7 and 8).

A fastening tube 20, which is mounted on the mouth tube 80 of the bottle unit 8, is provided with an inner flange 24 in an upper area of an inner circumferential surface. A sealing tube 26, having a straight cylindrical configuration, is placed on an upper surface of the inner flange 24. An erect tube 27, which is relatively tall and tapers upwards, is positioned from an internal periphery of the inner flange 24 , is provided with window openings 28. These window openings 28 are provided in three positions, equally spaced from each other in a circumferential direction, in order to stabilize the erect tube 27 structurally, to prevent this erect tube 27 from being deformed and deviated from an axially aligned position, due to aging and ensuring that air and liquid flow uniformly through the window openings 28, without being influenced by the turning direction of the bottle unit 8. On the inner circumferential surface of the fixing tube 20, below the inner flange 24, a vertical control flange 22 is provided, which abuts against the vertical retaining flange 82 of the bottle unit 8 in the circumferential direction and against the circumferential flange 86 from the upper side. "This vertical control flange 22 of the fastening unit is firmly mounted in the vacant zone 87 of the bottle unit 8. Under this vertical control flange 22, flange 21 is disposed retention, which goes over the circumferential retention flange 81 of the bottle unit 8 for joining the lower cutout A pair of cavities 20a is provided on a lower end face of the fixing tube 20, in opposite positions diametrically to each other These cavities 20a are coupled with the projections 84 of the bottle unit 8, to retain the fixation arrangement of the fixing unit 2 immobile, with respec to the bottle unit 8 to a position aligned with the bottle unit. In the case of the modality shown in the Figures 4 and 6, a retaining flange 29 is disposed in a circumferential direction on the outer circumferential surface of the fastening tube 20, below the helical flange 23. A vertical rib is disposed between the retaining flange 29 and a helical flange terminal. 23. The vertical rib constitutes a dead end passage 23a, against which a terminal surface of a helical flange 40a is disposed on an internal wall of a change unit 4 at the downward limit of this change unit 4. Two pairs of lower vertical flanges 29a are disposed in diametrically opposite positions to each other, under the retaining flange 29. In addition, a fixing tube 25 is disposed under the inner flange 224 and is mounted firmly in the opening of the mouth tube 80. In the case of the embodiments shown in Figures 7 and 8, a pair of guide grooves 23b are arranged in diametrically opposite positions with each other, with both the upper and lower ends, being flat and not having an inclination. A lower terminal end of the guide groove 23b defines a dead end passage 23a against which the projected guide pieces 40a of the shift unit 4 abut. At an upper terminal end, the guide annulus 23b is provided with a vertical insertion groove 23c with which a projecting guide part 40b of the change unit 4 engages and joins. In the case of the guide slots 23b, in the embodiment shown in Figures 7 and 8, even if the upward / downward displacement of the shift unit 4, relative to the relative rotational movement, is adjusted larger by increasing the angle of inclination, the position of the vertical displacement of the shift unit 4 can be held stably against the external force, as long as the guide grooves 23b have flat terminal ends.

The vertical control flange 22 of the fixing unit 2 is inserted into the vacant zone 87 and is engaged there to align this fixing unit 2 directionally with respect to the bottle unit 8. Next, the vertical control flange 22 is forcedly pushed against the bottle unit 8 to cause the retaining flange 21 to engage with the circumferential retention flange 81 for attachment of the lower trim. Additionally, the cavities 20a engage the projections 84 of the bottle unit 8, so that the fixing unit 2 is firmly attached to the mouth tube 80 of the bottle unit 8. The strong connection is obtained by inserting the fixing tube 25 strongly into the opening of the mouth tube 80 of the bottle unit. A shutter unit 3 (see Figures 2 and 9) comprises a mounting portion 30 of a thin cylindrical configuration, provided with a roof. The outer sealing flange 31, which is somewhat thick, is disposed in a circumferential direction at a medium ht position of the outer circumferential surface of the mounting portion 30. A projecting obturator piece 33 of an erect slender rod configuration is erected from the center of a flat upper sealing surface 34. In the cylindrical wall, just below the outer sealing flange 31 of the mounting portion 30, holes 32 are provided. of communication, which help the flow of the liquid from inside the bottle unit 8 to a measuring chamber A. A support portion 35 is arranged on the outer circumferential surface of the mounting portion 30, just below the communication holes 2, and is used to adjust the insertion and attachment boundary to the erect tube 27 of the fixing unit 2. The shutter unit 3 is securely attached to the fixing unit 2 by mounting the retaining flange 27a of the erect tube 27 in a circumferential retaining groove 30a, which is disposed in a circumferential direction in the mounting position 30, below the support portion 35, and mounts a plurality of vertical retention flanges 30b in the vertical retention grooves of the erect tube 27. The change unit 4 comprises a main tube 40 of cylindrical configuration. A helical flange 40a, which engages the helical flange 23 (see Figure 10), or projected guide pieces 40b, which are mounted in the guide slots 23b (see Figures 11 and 12), is disposed on a surface of internal circumference of the main tube 40. A ring 43 of upper plate of an internal flange configuration is connected to the upper end of the inner circumferential surface of the main tube 40. An inner tube 45, which is inserted, firmly and slidably, in the sealing tube 26 of the fixing unit 2 and in which the external sealing flange 31 of the sealing unit 3 is mounted firmly in an upper opening of the inner tube 45, is connected to an inner circumferential periphery of the ring 43 of the plate upper in a central position of the main tube 40. A plurality of parts 41 that prevent the escape, which are provided with adjoining convex portions, 41a, in the interior, and a plate 48 that produces sound, of thin plate, having a surmountable convex portion 48a therein, integrally connected to the lower periphery of main tube 40 through thin portions 41b and thin portion 48b, such that they can be bent and in an expanded state . This surmountable connected portion 48a projects more than adjacent abutting portions 41a- A projection 41c which produces a low click sound is provided on the projecting end face of the adjoining convex portion 41a of the part 41 preventing the escape, which is placed in a position diametrically opposite the piece 48 that produces sound. A circumferential sealing rim 46 is provided on the lower periphery of the outer circumferential surface of the inner tube 45 in order to secure and strengthen the firm contact of the inner tube 45 with the sealing tube 26 of the fixing unit 2. A pair of vertical coupling slots 42, and a circumferential coupling slot 47, are provided in the upper half area of the outer circumferential surface of the main tube 40. A cylindrical fixing portion 44 of a short cylindrical configuration, having a circumferential rim on its circumferential surface internal, is provided in a middle position in the upper plate ring 43. Thus, the main tube 40 is threadedly mounted on the fixing tube 20, so that this main tube 40 is moved up and down with a certain stroke, by the relative rotation between them. The change unit 4 is attached, in non-releasable form, to the fixing unit 2, because the adjacent convex portions 41a abut against the retaining flange 29 from the bottom side, as described below. The change unit 4 is firmly attached to the fixing unit 2 by the insertion of the inner tube 45 in the sealing tube 26. At the ascending limit, ie in the state of application of the liquid, the inner tube 45 is firmly mounted on the external sealing flange 31 of the shutter unit 3, whereby a side of the bottle unit 8 is sealed. The operation unit 5 (see Figure 13) comprises a cylindrical outer tube 50, which is mounted on the main tube 40 of the change unit 4, without a gap, and an upper tube 54, having a dome-shaped top wall, which is connected to an internal flange of narrow width, provided in an upper position of the outer tube 50. The upper tube 54 forms a measuring chamber A, which has a constant volume together with the ring of the upper plate and the inner tube 45 of the switching unit 4. A pouring tube is placed on an upper end, the central portion of the dome-shaped top wall. An inner diameter of an upper middle portion of the pouring tube, which serves as a pouring nozzle 55, expands to be an expanded opening 57.

Thus, an opening of the application side of the pouring mouth 55 becomes a large opening area through the expanded opening 57. With this structure, the application capacity is improved without increasing the area of the pouring passage. The expanded opening 57 forms a pool of liquid and, therefore, the application of the liquid is continued uniformly and favorably without interruption. An immobile fixation of the operation unit 5 to the change unit is achieved by providing, in the upper half of the inner circumference surface of the outer tube 50, a pair of vertical long and short flanges 51, which engage with the pair of vertical coupling slots 42 of the shift unit 4; and a circumferential flange 56, which engages with the circumferential coupling slot 47. A firm coupling of the operation unit 5 with the change unit 4 is achieved by supplying a short fit tube 53 of tight fit, which is mounted firmly on the fixing tube 44 at one end of the inner circumference of a lower surface of the internal flange 52. The vertical flanges 51 are different in length, that is, the height positions of the lower ends of the vertical flanges 51 are different. This is because the operation unit 5 is adjusted in the predetermined direction, when assembled by the automatic assembly machine. This makes it possible to direct a previously given mark on an outer circumferential surface of the operation unit 5, always in alignment with a previously given mark on an outer circumferential surface of the fixing unit 2. When the operation unit 5 is mounted on the shift unit 4, the parts 41 preventing leakage and the sound producing part 48 of the shift unit 4, which are in the extended state, are pushed by an end surface bottom of the outer tube 50 of the operation unit 5, and are folded inwardly into the thin portions 41b and 48b (see Figure 1). Due to the folding displacement of the parts 41 preventing the escape and the sound producing part 48, the adjoining convex portions 41a of the parts 41 preventing the escape, engage with the retaining flange 29 from the bottom side, such that they can not go over the retaining flange 29, so the rising limit for the change unit 4, with respect to the fixing unit 2, is adjusted. As the operation unit 5 is operated rotationally, the surmountable convex part 48a of the sound producing part 48 and the projection 41c which produces a click of the part 41 preventing the escape, respectively go over the vertical flanges 29a and make a sound of click and give a sense of this clicking sound, before the ascending limit and the descending limit for the change unit 4 in the rotation displacement, in relation to the fixing unit 2. A valve unit 6 (see Figures 14 and 15) comprises a short cylindrical valve head 61, with a height greater than the spout 55 and a thickness to fit closely in the spout 55. The valve head 61 is provided with several vertical grooves 63 (3 in the drawings) on the upper half of an outer circumferential surface and with a vertical hole 62 through the center. The valve unit 6 also comprises a valve seat 64, which is disposed under the valve head 61 and has an upper tapered surface, with a downward inclination extending towards its end. Various helical spring elements 65 (3 in the drawing) provide an elastic force and connect to the valve seat 64 at the upper ends. These several elastic elements 65 are respectively fixed to the upper internal surfaces of a plurality of fixing plates 66 of a rectangular configuration at their lower ends. The fixing plates 66 are placed on an inner edge of an upper surface of a fixing ring 60 having a coupling flange on an outer circumferential surface. The valve unit 6 is attached to the change unit 4 by adjusting the clamping ring 60 in the clamping tube 44 of the change unit 4 to effect the coupling of the cut-out. The fixing plates 66 of the valve unit 6 are formed to have a height substantially close to the height of the inner tube 45, so as to obtain a volume of the measuring chamber A, occupied by the elastic elements 65, when they deform as little as possible. The upper ends of the elastic elements 65 are connected to portions of the valve seat 64, which extend equi-angularly from the periphery of the valve feel, so that the portions connected with the upper ends of the elastic elements 65 do not affect the valve closing action of the seat 64 of valve. A bottom surface of the valve seat 64 is a flat surface, with which the upper sealing surface 34 of the shutter unit 3 can come into contact. The vertical bore 62 of the valve head 61 has a diameter in which the part 33 of the obturator projected from the shutter unit 3 can be mounted loosely (see Figure 1). A lid unit 7 (see Figures 1 and 16) is structured to be a duplicate structure, comprising an outer lid 70 and an inner lid 74. This outer lid 70 has a configuration of an elliptical tube, provided with an upper plate 72, and has a pair of convex coupling portions 71, in diametrically opposite positions to each other, and a lower end of an inner circumferential surface, the inner cover 74 has a dome-like configuration, which covers the operation unit 5 and it is fixed to the upper plate 72 of the external lid 70. This internal lid 74 is provided with a shutter tube 73, for sealing the spout 55.

The lid unit 7 is removably attached to the bottle unit 8 by contacting the convex portions 71 of coupling with the concave coupling portions 85 of the bottle unit 8. At that time, an inner surface of the dome-type inner lid 74 serves as a guide surface for an upper part of the pouring and application plug 1, and thus the lid unit 7 can be mounted easily and evenly. Figures 17 to 19 show a second structured mode to prevent the wrong opening / closing operation of the pouring and application shutter 1. A base tube, connected to a lower end of the fixing tube 20 of the fixing unit 2, by a connecting flange 24c, is structured to be a flange tube 24a, arranged directly under the operating unit 5 at its downward limit . Cutouts 24d are provided in portions of the flange tube 24a and the connection flange 24c positioned on the front and rear, so that the front and rear portions of the flange tube 24a are formed to be displaceable sections 24b, which can be displaced flexibly in the radial direction. Each of these movable sections 24b is provided with hooks 24e.

The shutters 58 are disposed at the lower end of an inner circumferential surface of the outer tube 50 of the operation unit 5. This outer tube 50 is inhibited from upward rotation by these shutters which engage the hooks 24b. In this second embodiment, the operation unit 5 will be rotated to ascend, due to the engagement of the shutters 58 with the hooks 24e, in the measurement state, that is, when the operation unit 5 is located at its downward limit and the 55 pouring mouth can not be opened. This engagement of the hooks 24e with the shutters 58 is released by holding both displaceable sections 24b with the fingers and pushing them from the front to the rear. At that time, the operation unit 5 obtains the state supplying the upward rotation and thus the discharge and application shutter 1 can be changed from the measurement state to the application state. Figures 12 to 23 show a third embodiment, in which a lid assembly / removal unit 9 is attached to an upper portion of the bottle unit 8, in order to prevent the assembled lid unit 7 from being removed in a manner wrong This lid assembly / removal unit 8 comprises a fixing tube 90, which is mounted on the bottle unit 8. A flange 98 preventing leakage, for coupling with an external flange 83 of the bottle unit 8, from the lower side, it is disposed in a circumferential direction on an internal surface of the fixing tube 90. A portion 91 of the support tube of a substantially elliptical configuration extends downwardly from the lower edge of the fixation tube 90. The portion 91 of the support tube is mounted on a small-diameter fastening portion 88 of the bottle unit 8, which is formed for the cover assembly / removal unit 9, to be attached and is a portion of the container. support of the bottle unit 8, reduced in diameter. The suspended wall sections 93, which are adapted for coupling with recessed sections 89, formed in the upper portion of both side portions of a barrel portion of the bottle unit 8, by means of abutting steps 92, which face upwards , are formed at the edges of the lower end of both side portions of the support tube 91. The tongue-like wall sections 94 are formed by slots 96 of cut-out in the form of a gate on portions extending from the wall sections 93 suspended to the portions 91 of the support tube. The tongue-like wall sections 93 are provided with latching flanges 95 on the upper part of an external surface, which is one end of the tumbling. When the lid unit 7 is placed in the bottle unit 8, to which the pouring and application plug 1 is attached, this lid unit 7 is assembled to the bottle unit 8 in a state that its lower end edge is in contact with the abutting steps 92 and the engagement ridges 95 are in contact with the coupling projections 71, so that the cap unit 7 can not be removed from the bottle unit 8. To remove the lid unit 7, the tongue-like wall sections 94, which are arranged directly under the lid unit 7, and are provided with a plurality of finger-engaging ridges 97 on their surface, are pushed to to be turned inside and to free the coupling of the engagement flanges 95 with the coupling projections 71. In this state, the lid unit 7 is pulled upward away from the bottle unit 8. All the components of the pouring and application plug 1 and the lid unit 7, which include the lid assembly / removal unit 9, are molded using synthetic resins, which are adapted to the functions required for the components. In the case of the pouring and application plug 1, for example, polypropylene is a material suitable for the fixing unit 2, due to its elastic deformability for the clipping coupling with the bottle unit 8, made of a hard material, seal maintenance after coupling, and high resistance to aging. The polypropylene is also suitable for the shutter unit 3, because this unit 3 is integrally combined with the fixing unit 2 to constitute a main part and because the external sealing flange 31 is firmly mounted on the inner tube 45 of unit 4 of change, in order to obtain a strong seal. Since the change unit 4 is softer than the fixing unit 2, the hard polyethylene is suitable for the molding material, because this material gives a high sealing property through the firm sliding contact and has a resistance of pretty low friction against polypropylene. The operation unit is suitably made of polypropylene, due, similarly to the fixing unit 2, that the operation unit 5 is required to have a firm fixing relationship with the binding unit 4 of change and also due to the demand, can in the demand, become necessary for the operation unit 5 to be able to have transparency. As the material for the valve unit 6, the polyethylene can be suitably used to give high elastic recovery and high sealing performance of the air-tight compartment. The lid unit 7 is suitably made of polypropylene for the easy deformation required in the coupling with the bottle unit 8 of a hard material. The polypropylene is also suitably used for the lid assembly / removal unit 9, in order to maintain the configuration of the lid in a stable way and to provide the elastic deformation.

ADVANTAGES OF THE INVENTION The present invention has the structure described above and, therefore, results in the following advantages. In the invention, according to claim 1, the lower ends of the helical elastic elements, which constitute the valve unit for opening and closing the pouring nozzle, are fixed to the upper portions of the fixing plates, which have a height substantially equal to the depth of the measuring chamber. Therefore, the valve unit rarely affects the change in the capacity of the measuring chamber, even if the elements are not constant in their way of elastic deformation. This invention thus makes it possible for a precise quantity of liquid to be measured and poured. Only by pressing the valve head down on the surface to be applied can the precise and adequate application of the contained liquid be achieved. Since the lower portions of the elastic elements of the valve unit, whose distance between the adjacent elements is maximum, are fixed to the hard fixing squares in the handling of the valve units, before they are installed to the containers for the pouring and application of a constant amount of liquid, it is prevented by the fixing plates that the valve heads and the like enter the lower end portions of the elastic elements of other valve units. Therefore, confusion between the valve units and the handling of the valve units themselves is thus improved. In this invention, according to claim 2, since a plurality of pieces that prevent the escape are arranged around the lower periphery of the change unit in the. extended state, the adjoining convex portions inside these parts that prevent the escape, do not come into contact with the helical flange and the retaining flange of the fixing unit, during the assembly of the change unit to the fixing unit , in the steps of the assembly of the containers to pour and apply a constant amount of liquid.- Therefore, it is easy and simple to join the change unit to the fixing unit, and there is no fear that part of the helical flange or other ridges are permanently deformed.

These pieces that prevent the escape are displaced and folded inside, when the operating unit is mounted on the fixing unit. Accordingly, the abutting convex portions abut against the retaining flange at the rising limit for the change unit.
