  • liquids there are considered writing liquids such as China ink, a paint, ink and etc., toilet lotions such as eye liners, lip colors, manicures and etc., liquid seasonings, machine oils and cleaning liquids.
  • the rear portion of the container is supported by an outer sheath having a contact wall for limiting the degree of recovery of the volume of the container and when the container is supported by the contact wall of the outer sheath, a small clearance is provided between the rear end of the valve rod and the inner wall of the rear end of the container.
  • an object of the present invention is to provide a liquid discharge instrument which can prevent the dripping of a liquid therefrom even when the instrument is kept pressed.
  • Another object of the present invention is to provide an inexpensive liquid discharge instrument capable of meeting the recent consumers' demand for inexpensive products in various fields of industry.
  • a liquid discharge instrument having the structure such that a liquid is received within a container capable of reducing and recovering its volume and having an opening at the distal end thereof, a valve comprising a valve seat and a valve rod with a first valve portion capable of repulsively contacting the valve seat is disposed within the opening of the container with the valve rod extending up to a rear portion of the interior of the container whereby when the rear end of the container is pressed, the valve rod is moved forward and the container deforms to open the valve thereby allowing the liquid to be discharged outside the container.
  • this liquid discharge instrument is characterized by the additional provision of a second valve portion at the intermediate portion of the valve rod so that when the valve rod is moved forward, the valve is closed by this second valve portion.
  • a liquid discharge instrument having the structure such that a liquid is received within a container capable of reducing and recovering its volume, a coating body is provided at the distal end of the container and a bellows portion capable of contraction and expansion in the longitudinal direction of the container is formed integral with the container with the thickness of the bellows portion being made smaller than that of the remaining portion of the container.
  • a liquid discharge instrument having the structure such that a drawing head in the form of a bundle of fibers is attached to the distal end of the above-mentioned container through a fixing tube which is vertically split into two halves in such a manner that these two halves are connected to the base portion of the fixing tube on one side while they are made flexible on the other side and further, a tubular portion to be inserted into the drawing head is formed integral with the base portion of the fixing tube.
  • Fig. 1 shows a first embodiment of the present invention which is a nail coloring instrument comprising a container 1 having a manicuring tool received therein.
  • the container 1 includes a self-elastic bellows portion 2 at the center thereof.
  • the self-elastic portion 2 is made of polyethylene, polypropylene, nylon, ethylene-vinyl alcohol, etc. by a blow molding and the like.
  • the container 1 has an opening at the distal end thereof and a valve seat member 3 is press-fitted into the opening.
  • the valve seat member 3 may be made integral with the container 1.
  • a valve rod 4 is constantly urged backward by a repulsive spring means 5 such as a coil spring stretched between it and the rear end of 00the valve seat member 3.
  • the repulsive spring means 5 may be disposed ahead of the valve rod 4 or may be formed integral with the valve rod 4 or the valve seat member 3.
  • the valve rod 4 extends through the interior of the container 1 so that a small clearance 6 is formed between the rear end thereof and the inner wall of the rear end of the container 1. Further, the rear end of the container 1 forms itself a knock body 7.
  • the valve seat member 3 has at substantially the intermediate portion thereof a small-diameter portion 3a which forms itself and serves as a valve seat portion designated at the same reference numeral 3a.
  • valve rod 4 comprises a first valve rod 8 and a second valve rod 9 such that the distal end of the first valve rod 8 forms a first valve portion 8a which abuts against a first end face of the valve seat portion 3a and closes a valve hole 3b.
  • the distal end of a second valve rod 9 forms a second valve portion 9a which abuts against a rear end face of the valve seat portion 3a and closes the valve hole 3b.
  • the second valve portion 9a is formed by making the diameter of the second valve rod 9 larger than that of the first valve rod 8 but both the first valve rod 8 and the second valve rod 9 are formed integral with each other and the first valve portion and the second valve portion may be formed as large-diameter portions, respectively.
  • a drawing head (or writing nib) 10 formed of a bundle of fibers and a drawing head fixing tube 12 having a porous member 11 serving as a temporary liquid reservoir (trap) for the drawing head 10 is attached to the distal end by suitable means such as press-fitting, screw-fitting, bonding or the like.
  • suitable means such as press-fitting, screw-fitting, bonding or the like.
  • the drawing head 10 and the porous member 11 are in communication with each other through a cylindrical body 13 thereby facilitating the circulation of a liquid through the drawing head 10 at the time of starting the use of the instrument.
  • Reference numeral 14 designates an air exchanging slit so formed in the valve seat member 3 that air selectively passes through comparatively large gaps having weak capillary attractions and enters into the container 1.
  • Reference numeral 15 designates an outer sheath so formed as to cover the container 1 in its entireties. Further, to the rear end of the outer sheath 15 there is attached, by press-fitting, a stopper ring 16 which leaves about one half of the knock body 7 of the container 1 exposed. The exposure of the knock body 7 is made possible by forming a recess 16a on the stopper ring 16. The reason why the degree of exposure of the knock body 7 is made to be about half the length of the knock body is that the knock body is prevented from being unnecessarily pressed due to an unexpected external force.
  • stopper ring 16 also prevents the slipping off of the container 1 from the outer sheath 15 by the formation of a projection on the inner peripheral surface thereof.
  • Reference numeral 17 designates a cap which is removably screw-fitted on the distal end of the container 1 or it may be attached to the latter by convex-concave fitting or it may be merely press-fitted to the latter.
  • the valve is opened and the liquid in the container is pressed, so that even when the liquid is of comparatively high viscosity, it can be discharged with ease.
  • FIG. 5 A second embodiment of the present invention is shown in Figs. 5 and 6.
  • This is a case in which the side surface of an outer sheath 18 corresponding to the outer sheath 15 of the first embodiment shown in Fig. 1 is pressed in the radial direction to open the valve and the interior of the container 1 is pressed.
  • At the front portion of the outer sheath 18 there are formed U-shaped slits 19 so that pressure pieces 20 are formed to lie opposite to each other.
  • each of the pressure pieces 20 is provided with a projection 21 which can abut against a front shoulder 22 of the container 1.
  • the rear end of the outer sheath 18 is sealed with a tail plug 23 so that the backward movement of the container 1 is inhibited.
  • the top end of the each of the projections 21 is tapered and the front shoulder portion 22 has an inclined surface so that the container 1 is moved backward with ease by the pressing operation of the pressure pieces 20.
  • a clearance 6 is provided between the rear end of the valve rod 4 and the inner surface of the rear end of the container 1 so as to prevent the valve form being opened due to an unexpected application of pressure on the container.
  • Reference numeral 24 designates a container body formed by blow-molding a material such as polyethylene, polypropylene, nylon, a copolymer of ethylene and vinyl alcohol and behind the container body 24 there is formed a bellows portion 25 capable of contraction and expansion in the longitudinal direction of the container body 24. Further, behind the bellows portion 25 there is provided a bottom 26 which forms itself a pressure portion 27. The central portion of the bottom 26 becomes depressed inwardly as at 28 with respect to the container body 1 and this depression 28 serves as a means for preventing a parting line generating at the time of molding from projecting from the surface of the bottom 26.
  • the thickness of the bellows portion 25 is made smaller than the thickness of the container body 24 and the pressure portion 27.
  • each of side portions 25a and each of outer ridges 25b of the bellows portion 25 are made thinner and each of inner ridges 25c of the bellows portion 25 is made thicker.
  • the outer ridge 25b deformable while the inner ridge 25c is made to have a suitable degree of rigidity the elasticity of the bellows portion 25 with respect to its contraction and expansion is improved. (see Fig. 8).
  • each of the side portions 25a, each of the outer ridges 25b and each of the inner ridges 25c may be made to have the same thickness as shown in Fig.
  • valve seat member 31 To the opening at the distal end of the container body 24 there is attached a valve seat member 31 into which a drawing head fixing tube 30 having a drawing head 29 is press-fitted but this valve seat member 31 may be made integral with the container body 24.
  • a valve seat portion 31a Inside the valve seat member 31 there is formed a valve seat portion 31a and with respect to this valve seat portion 31a (valve seat member 31) , a valve rod 32 is constantly urged backward by means of a repulsive member 33 such as a coil spring stretched between it and the valve seat portion 31a (valve seat member 31).
  • the repulsive member 33 may be arranged ahead of the valve rod 32 or may be made integral with the valve rod 32 or the valve seat member 31 as the case may be or it may be dispensed with only if the elasticity of the bellows portion 25 ( effect of elasticity) is sufficiently strong.
  • the valve rod 32 extends through the container body 24 and between the rear end thereof and the inner wall of the rear end of the container body 24 (inside the depression 28 of the pressure portion 27) there is provided a small clearance 34.
  • valve rod 32 comprises a first valve rod 35 and a second hollow valve rod 36.
  • the first valve rod 35 is provided at the distal end thereof with a first valve portion 35a capable of coming into contact with the front end face of the valve seat portion 31a and closing the valve hole 31b.
  • the second valve rod 36 is provided at the distal end thereof with a second valve portion 36a capable of coming into contact with the rear end face of the valve seat portion 31a and closing the valve hole 31b.
  • a stopper ring 37 for preventing the flexing of the valve rod 32.
  • the stopper ring 37 is provided with radially extending vertical grooves 38 for improving the circulation of a liquid (see Fig. 10).
  • reference numeral 39 designates a ball for agitating a toilet lotion within a container 24 but the ball 39 is not always necessary depending on the kind of liquid being used.
  • a porous member 40 serving as a temporary liquid reservoir leading to the drawing head 29.
  • the drawing head fixing tube 30 comprises a fixing tube halves 40 and 41 formed by vertically dividing the tube 30 in such a manner that each of the tube halves can flex on one side and connected to a base portion 42 of the tube on the other side. Further, at the center of the base portion 42 there is integrally erected a cylindrical pipe 43 to be inserted into the above-mentioned writing nib or drawing head 29.
  • the drawing head fixing tube and the cylindrical pipe 43 integral with each other, the parts manufacturing cost can be reduced and by dividing the fixing tube into two parts, the insertion of the drawing head into the fixing tube is facilitated. Further, as a matter of cause, the production cost can be reduced by facilitating the operation of assembling the parts.
  • each of the fixing tube halves 40 and 41 there are formed an air exchanging slit 44 and a groove 45 for stopping and fixing a welded portion 29a at the rear end of the drawing head 29. Further, on the side surface of the base end 42 there are formed air exchanging slits 46 in opposite relationship with each other.
  • reference numeral 48 designates a cap removably attached to the container 24 by screw-fitting means.
  • This cap 48 is of a double-cap structure comprising an outer cap 50 and an inner cap 51 connected through a plurality of ribs 9.
  • a circumferential groove 52 is formed inside the outer cap 50 for the purpose of allowing a head cap 53 to be inserted if so desired as shown in Fig. 14 because by so doing, the upper aperture of the cap 48 is closed to make the entire product good looking.
  • a screw-threaded portion 54 of the cap 48 is provided at the central portion thereof with a groove 55 along the helical portion thereof.
  • This is a means provided for preventing the occurrence, at the time of injection-molding the cap, of a sink (i.e. the formation of a dent on the surface of a molded product immediately after molding due to the contraction of the volume of the product taking place more frequently at a large thickness portion than at a small thickness portion of the product) or for preventing the loosening of the cap itself.
  • Fig. 16 shows an example in which there is provided inside a container body 56 a soft bag 57 which contracts in sequence according to the use of a liquid (a toilet lotion).
  • a liquid a toilet lotion
  • the bag 57 for storing the liquid contracts due to a decrease in the amount of the liquid so that not only air but also various kinds of bacteria contained in the air are not mixed in the liquid so that the container is quite sanitary and the drying of the liquid is also prevented.
  • Fig. 17 shows an example in which a comb-tooth shaped coating head 58 instead of the bundle of fibers in the example 1 is attached to the distal end of the container.
  • This coating head is mainly used for a hair coloring instrument.
  • various kinds of coating heads can be attached.
  • the liquid discharge instrument has the structure such that a liquid is received in a container whose volume can vary to decrease and recover, a valve comprising a valve seat portion and a valve rod having a valve portion capable of repulsively contacting the valve seat portion and extending up to the rear portion of the container is disposed in an opening of the distal end of the container and when the rear end of the container is pressed, the valve rod moves forward and the container deforms to open the valve portion to thereby discharge the liquid outside the container, and is characterized in that the valve rod is provided with a second valve portion at the intermediate portion thereof so that when the valve rod moves forward, the valve is closed.
  • the liquid discharge instrument has the structure such that a liquid is received in a container whose volume can vary to reduce and recover, a coating member is provided at the distal end of the container and a bellows portion capable of expansion and contraction is formed integral with a portion of the container with the thickness of the bellows portion being made smaller than that of the remaining portion.
  • the liquid discharge instrument has the structure such that a liquid is received in a container capable of reducing and recovering its volume and a coating head comprising a bundle of fibers is attached to the distal end of the container wherein the coating head is attached to the container through a fixing tube which are split into two halves connected to each other at the base thereof and capable of flexing at the free ends thereof and further, a tubular portion to be fitted in the coating head is formed integral with the base.
