Definitions

  • the present invention relates generally to a fluid container and more particularly, to a push-knob fluid container capable of ejecting a fluid substance contained in the container at fixed amount through an outlet pipe by the push with finger of the knob provided at the top of the container cap.
  • a good many containers are available at the market for containing therein fluid substances, such as shampoo, washing cream and others. Since these containers are not of a type for quantitative extraction of the content, it must rely upon the observation and the sensation of push by the user to carefully release the content for use. This is not only inconvenient in manipulation and the use of the container, but because of excessive amount being squeezed out it always results in wastage. Recently, there is known a kind of containers where the fluid content can be extracted quantitatively by the push of a knob, such as, the type of squeezable container for toothpaste. However, the complication in construction, the relative difficulty in the production and the higher cost are the drawbacks of this kind of containers.
  • the invention has thus for its aim to develop a push-knob fluid container in order to solve the above known drawbacks.
  • an object of the present invention is to provide a novel push knob fluid container equipped with a fixed delivery mechanism, capable of moving the pusher piston forward to thereby deliver the contained fluid substance quantitatively through a discharge hole by gentle push of the knob or the cover and through a unidirectionally driven motion change mechanism.
  • Another object of this invention is to provide a push-knob fluid container suitable for receiving and packaging hygienically in entirety all kinds of milk, cream or liquid fluid matter while being capable of delivering quantitatively the contained substance by simple manipulation.
  • Still a further object of the present invention is to provide a push-knob fluid container capable of regulating the delivery amount by the adjustment of the press stroke of a drive mechanism and also capable of squeezing out a large amount of the contained substance at one time by short stroke push manipulation.
  • Another object of the present invention is to provide a push-knob fluid container capable of discharge action during both the press stroke and the return stroke by the recovery of spring whereby a double discharge amount is obtained and energy is saved.
  • a further object of the present invention is to provide a push-knob fluid container capable of achieving the aforesaid efficacy with the most simplified assembly construction and at the lowest cost of production.
  • the fluid container of the invention comprises essentially: a usually cylindrical container body 1, a drive mechanism 2 disposed inside a drive chamber A at the upper end of the container body 1 and capable of converting linear motion into rotary movement, a driven mechanism 3 disposed likewise in the drive chamber A of the container body 1 and having a screw rod 32 extending into the bottom inside the container 1 and driven by the drive mechanism 2 to be unidirectionally rotatable, a discharge or delivery piston 4 provided at the lower end of the screw rod 32 of the driven mechanism 3 and capable of ascending along the screw rod 32 following the rotation of the latter to push the contained matter out, and a push knob 5 mounted on the upper part of the container body 1.
  • the container body 1 has openings 11, 12 at the upper and lower ends,the opening 11 at the upper end being covered with a cap 13, whereas at the lower end there being provided with a cylindrical body having a bugle-shaped bottom seat 14.
  • a circular plate-like support seat 16 On the inner wall at the upper end portion of the main body 1 there is located a circular plate-like support seat 16 having in the center a hole 15 and on the circumference formed with a plurality of through holes 15, whereas in between this supporting seat 16 and the upper cap 13 there is appropriately formed a drive chamber A.
  • the central hole 13 a formed on the cap 13 is provided with a projecting square positioning guide groove 13 b .
  • the drive mechanism 2 is located inside the drive chamber A and comprises a drive screw 21 of greater lead and a drive pawl wheel 22 disposed at the lower end of the screw 21 and having a multiplicity of elastic pawls 24.
  • This drive mechanism 2 is for converting the linear motion into rotary motion and drives the driven mechanism 3 to rotate.
  • the driven mechanism 3 includes an internal pawl type ratchet wheel 31 disposed inside the drive chamber A and driven by the above pawl wheel 22 to be unidirectionally rotatable, and a guide screw rod 32 connected to the lower center of the ratchet wheel 31 and passing through the central hole 15 a of the support seat 15 to extend into the lower end of the container body 1 for guiding the piston 4.
  • the inside wall of the ratchet wheel 31 is provided with a plurality of unidirectional internal pawls 33 to mesh with pawls 24 of the pawl wheel 22, whereas on the bottom plate thereof there is a plurality of penetration holes 34.
  • the delivery piston 4 is located in the interior of the container body 1 and which, when the container is filled with a contained fluid, is located at the lower part of the container body 1 and is screwed onto the lower end of the guide screw rod 32.
  • this piston comprises a cylindrical body 41 having the circumference closely touching the inside wall of the container body 1 and a metal nut member 44 embedded in the center of the upper or bottom wall of the piston body 41 and provided with a plurality of radially arranged internal pawls 42 and a plurality of external pawls 43.
  • the internal pawls 42 of the nut member 44 mesh with the guide screw rod 32 and possess the function of a nut.
  • the external pawls 43 are locked in engagement by the downwardly inclined angles and the elasticity at the ends of the pawls 43 with the inner circumferential wall of the container body 1 and are able to ascend readily along the said wall but not to descend. These external pawls 43 also will not rotate but to shift unidirectionally only. In other words, the plurality of external pawls 43 has the function of stopping the descent so as to allow the piston 4 to ascend by the positive rotation of the guide screw rod 32. The piston 4, however, will not fall down because of the weight of the contained substance it is subjected to, nor will it turn reversely because of the reverse rotation of the drive pawls 22. In the place of the foregoing nut member 44, simply a nut may however be used.
  • Push knob 5 comprises a head 51 having a L-shaped delivery pipe 52, a drive pipe 55 having the pipe orifice at the upper end connected to the delivery duct 52 of the head 51 and the lower end extending into the drive chamber A and in which the lower end is provided with a disc 54 having on the circumference a seal ring 53 and an axial guide ridge 58, a drive guide plate 56 mounted below the disc 54 of the drive pipe 55 and a knob-return spring 57 disposed in between the guide plate 56 and the drive pawl wheel 22.
  • the drive guide plate 56 is defined in the center with a somewhat eight-shaped drive hole 59 screwed onto the upper end of the screw 21 of greater lead and is provided on the circumference with a plurality of through holes 50 capable of communicating with the drive pipe 55. Also, the guide plate 56 is constantly endowed with an upward pressure forcing the upper side of the disc 54 to press against the upper part inner side of the cap 13 by the force of the return spring 57.
  • the drive pawl wheel 22 and the driven ratchet wheel 31 described above constitute appropriately a unidirectionally rotating ratchet mechanism M.
  • This is the unidirectional mechanism which, when the drive pawl wheel 22 rotates in the set direction, is capable of driving the driven ratchet wheel 31 and bringing the latter into rotation in the same direction by the pawls 24 and which, however, when the drive pawl wheel rotates in the reverse direction, will allow the pawls 24 to pass over the internal pawls 33 of the ratchet wheel 31 and not to drive the ratchet wheel 31.
  • the bottom face of the pawl wheel 22 preferably is provided at the center thereof with a small protuberance 25 to be engaged in a cavity 35 at the center of the ratchet wheel 31.
  • a protuberance 17 on the part of the central hole 15 a of the support seat 16 there may also be formed a protuberance 17 to reduce the frictional force on the bottom face of the ratchet wheel 31.
  • the screw rod 32 is provided at the upper part thereof with projections and the support seat 16 with an annular groove whereby the two can be engaged to each other so that in rotation the screw rod 32 will not separate and fall off from the support seat 16.
  • the frictional force produced in relation to the ratchet wheel 31 is set to be smaller than the frictional force needed to move the ratchet wheel 31 to rotate in the positive direction. For this reason, when the pawl wheel 22 rotates in the opposite direction, it will not bring the ratchet wheel 31 into rotation. At the same time, the engaging force between the external pawls 43 of the delivery piston 4 and the inner wall of the container will also make the ratchet wheel 31 not to rotate in the opposite direction. However, to further ensure that the ratchet wheel 31 will not rotate in the reverse direction, it may also be done, as in the second embodiment of the present invention shown in FIG.
  • the pawls 33 of the ratchet wheel 31 are still able to slide over the elastic pawls 19 a of the fixed pawl wheel 19.
  • this ratchet wheel 31 becomes pushed against by the pawls 19 a and will not rotate.
  • the fixed pawl wheel 19 is of the same construction as the drive pawl wheel 22.
  • Any elastic pawls, whether single pawls or double pawls, may be used in so far as the pawls have the same function and effect as the pawl wheel 19, that is, have the function to permit the ratchet wheel 31 to turn positively but prevent it from turning oppositely.
  • the upper cap 13 is such that it covers superficially. It will be also possible if a cap 13 a of greater depth is used and if the height of the support seat 16 to the mouth of the container is shortened as shown in FIG. 6.
  • the container body 1 and the upper cap 13 are of the same diameter.
  • FIG. 7 illustrates the third embodiment of the present invention, in which, in order to reduce the frictional resistance produced between the outer circumferential wall of the driven ratchet wheel 31 and the inner circumferential wall of the container body 1 during operation, there are formed one or several annular raised lines 36 on the outer circumferential wall of the ratchet wheel 31 of the ratchet wheel mechanism M. It is to be understood that such raised lines 36 may be appropriately applied in the embodiments above mentioned and in embodiments hereinbelow described.
  • FIG. 8 illustrates a fourth embodiment of the present invention, which shows no difference in the basic making from those of the foregoing embodiments except in that, in order that the push knob 5 is able to still use its energy effectively to continuously drive the ratchet wheel 31 to discharge substance after the push knob 5 has been pressed and as the knob 5 is returning to its original position by the return spring 57, two sets of ratchet wheel mechanisms are used here. Specifically speaking, here in the drive chamber A there are arranged two completely similar upper and lower opposite units of ratchet mechanisms M1, M2, each unit including a set of drive pawl wheels 22 a , 22 b and driven ratchet wheels 31 a , 31 b .
  • the two driven ratchet wheels 31 a , 31 b are connected together as a single body with a cylindrical wall 37 and the return spring 57 is disposed in between the two upper and lower ratchet wheels 31 a , 31 b .
  • the drive screw 21 a passes through the upper cap 13, the two pawl wheels 22 a , 22 b and the ratchet wheels 31 a ,31 b and is provided on the upper end thereof with a push knob 5 whereas the lower end thereof extends into the hole on the upper end portion of hollow guide screw rod 32.
  • the drive screw 21 a is also firmly provided half-way with a stepwise positioning guide plate 56 also functioning as a check plate to press against the lower side of the upper ratchet wheel 31 a by means of the spring 57.
  • the screw 21 a with this stepwise positioning check plate 56 as the mark is divided into an upper section S1forming the right screw and a lower section S2 forming the left screw, while at the same time, the guide screw rod 32 forms the right screw.
  • the upper ratchet wheel mechanism M1 is thus driven by the right screw S1 of the upper section to turn positively thereby bringing the guide screw rod 32 into rightward rotation to further force the piston 4 to ascend.
  • the screw 21 a ascends by the force of the spring 57 when the push knob 5 is let go and during this time the lower ratchet wheel mechanism M2 being driven by screw S2 of the lower section is rotating in the rightward direction while concurrently the upper ratchet wheel mechanism M1 driven by screw S1 of the upper section performs the race rotation.
  • the guide screw rod 32 under the drive of the lower ratchet wheel mechanism M2 continues to rotate in the rightward direction and the piston 4 is still able to ascend continuously and to press the contained substance until the stepwise positioning check plate 56 reaches and is in contact with the bottom face of the upper ratchet wheel 31 a .
  • the drive pawl wheels 22 a , 22 b are next defined in the center with eight-shaped holes so that they also function to drive the guide plate.
  • the upper portion of teh container body 1 is provided near the drive chamber A with a discharge hole 52 passing into the interior of the container 1. Therefore, when the piston 4 ascends, the contained substance can be ejected out through the said discharge hole 52.
  • the support seat 16 is formed in a closed body to avoid the contained substance from entering into the drive chamber A.
  • the moving mechanisms M1, M2 inside the drive chamber A are able to perform even smoother and swifter actions.
  • the construction of the container with side discharging can be also applied in the above described first to third embodiments, in which, it only requires that the container body 1 is provided on one side at the upper portion thereof with a discharge hole and the support seat 16 is made a closed body, and at the same time the push knob 5 is made a simple structure without the delivery pipe 52. In this way, it is possible to manufacture the drive mechanisms to be even more compact and handy so that the volume of which occupying the container is reduced.
  • FIG. 9A shows a fifth embodiment of the push-knob fluid container of the present invention, in which an unidirectional crown gear mechanism is used in place of the aforesaid ratchet wheel mechanism M.
  • the aforesaid drive pawl wheels 22, 22 a and the driven ratchet wheels 31, 31 a are essentially substituted by a drive gear 22 b capable of driving unidirectionally only and a driven gear 31 b , while other structures remaining unchanged.
  • the discharge hole 52 is for side devivery and hence a simple knob is used for the push knob 5 having no delivery pipe.
  • FIG. 9B illustrates the fifth embodiment of the invention, in another aspect of variation and the discharge hole 52 thereof is located in the push knob 5.
  • FIG. 10 shows a sixth embodiment of the present invention.
  • the piston 4 has been described as being lifted up along the guide screw rod 32 under the weight of the contained substance to squeeze out the contained substance
  • the piston 4 is mounted on the upper part of the guide screw rod 32.
  • the container body 1 is formed with a bottom 1 a and the guide screw rod 32 is made into a hollow pipe having on the upper end openings passing into the drive chamber A.
  • the support seat 16 is formed in a closed body and the threads on the guide screw rod 32 are formed to be opposite to the direction of rotation of the driven ratchet wheel 31. In this way, the piston 4 moves from up to downwardly to squeeze the contained substance during the rotation of the guide screw rod 32.
  • a seventh embodiment according to the present invention is another embodiment of the piston 4 pressing downwardly from the above.
  • the upper end of the guide screw rod 32 and the support seat 16 are closed, however, a hole 10 is defined on the bottom 1 a of the container body 1.
  • This hole 10 is connected with a L-shaped delivery pipe 52 to project outwardly after it has upwardly extended to the apex of the body along the bottom 1 a of the container body and the outer side wall so that during the descent of the piston 4 it enables the contained susbtance to be squeezed and ejected out from this delivery pipe 52.
  • the push knob 5 immediately drives the ratchet wheel mechanisms M, M1, M2 to rotate by the drive guide plate 56 working against the force of the spring 57.
  • the guide screw rod 32 is moved to rotate by the mechanisms M, M1, M2 and following the rotating guide screw rod 32 the piston 4 moves either from top to bottom, as illustrated in FIGS. 1 through 9, or from bottom to top, as depicted in FIGS. 10 and 11, to squeeze out the contained substance through the delivery pipe 52. Because of fixed pressing stroke of the push knob 5, the stroke of movement in the piston 4 is also fixed and there is thus a fixed amount discharged upon pressing of the knob each time.
  • the push knob 5 is provided at the lower part with a regulating nut 50 a screwed onto a threaded portion 50 b formed on the outer circumference of the pipe or rod projecting at the lower end thereof.
  • a regulating nut 50 a it is possible to alter the pressing stroke S to further change the amount delivered.
  • the amount delivered each time by the container is proportional to the length of the pressing stroke of the knob.
  • the container body 1 is not to be limited to the cylindrical body, it is also possible if polygon cylinders such as hexagon cylinders, octagon cylinders, or other cylindrical bodies of appropriate shape are used.
