Definitions

  • the present invention relates to a container for discharging such liquid or fluidized substance as cosmetic milky lotion, cosmetic lotion, eau de Cologne, hair lotion, hand cream, foundation, shampoo, rinse, toothpaste, mayonnaise, ketchup, glue, tube colors, etc.
  • FIG. 39 One example of a conventional discharge container for discharging liquid contained in a liquid reservoir chamber through a discharge portion is shown in Fig. 39.
  • a pressure deformable soft container body 201 is served as a liquid reservoir chamber 202 in which liquid is stored. Formed on an upper part of the container body 201 is a discharge portion 203 on an outer periphery of which a screw portion 204 is formed. A cap 205 is removably threadingly engaged with the screw portion 204 in order to prevent drying and leakage of liquid at the time of non-use.
  • the cap 205 is removed from the container body 201, then the container body 201 is pressed by an appropriate amount, so that the liquid contained in the liquid container 202 is discharged through the discharge portion 203.
  • such toxic substance as bacteria- microbes, etc. is mixed into liquid, the liquid becomes an unsanitary liquid. Mold and color change occur in the worst case, resulting in extremely unsanitary liquid.
  • the liquid is cosmetic material or edible material, the situation can become very serious.
  • the container body 201 is formed of a pressure deformable soil material, there is a possibility that an equal amount of air to the amount of liquid used enters the inside of the container body 201 due to restoring function of the container body 201. This naturally enhances the speed of drying of, and the mixing density of bacteria- microbes into, the liquid.
  • a discharge container for discharging liquid contained in a liquid reservoir chamber through a discharge portion, comprising a liquid passageway for communicating the liquid reservoir chamber with the discharge portion; an elastic valve formed with a slit disposed on the discharge portion; and engagement means for preventing escape of the elastic valve from the discharge portion; the liquid reservoir chamber being variable in volume in accordance with consumption of the liquid.
  • a discharge container for discharging liquid contained in a liquid reservoir chamber through a discharge portion comprising a nozzle member, the discharge portion being formed in the nozzle portion, and an elastic valve disposed on the discharge portion and capable of movement under the effect of pressure of the liquid and projecting from a distal end of the nozzle member; the elastic valve being opened also by pressure of the liquid, the liquid reservoir chamber being variable in volume in accordance with consumption of the liquid.
  • a discharge container for discharging liquid contained in a liquid reservoir chamber through a discharge portion, comprising a liquid passageway for communicating the liquid reservoir chamber with the discharge portion; an elastic valve formed with a slit disposed on the discharge portion; the elastic valve being capable of movement forwardly and backwardly with respect to the discharge portion; a porous member arranged in the liquid passageway such that the porous member contacts the slit of the elastic valve when the elastic valve is moved backwardly.
  • a discharge container for discharging liquid contained in a liquid reservoir chamber through a discharge portion comprising a valve member formed of a porous member disposed on the discharge portion and having a valve hole at the discharge portion, said valve member being capable of movement backwardly under the effect of pressure of the liquid to open a valve hole of the discharge portion.
  • a discharge container for discharging liquid contained in a liquid reservoir chamber through a discharge portion, comprising a liquid passageway for communicating the liquid reservoir chamber with the discharge portion; an elastic valve formed with a slit disposed on the discharge portion; an air exchange passageway for communicating the liquid reservoir chamber with outside; a filter disposed on an intermediate portion of the air exchange passageway; and an air flow- in valve disposed between the filter and the liquid reservoir chamber and capable of dilating towards only the liquid reservoir chamber side.
  • the slit of the elastic valve is dilated under the pressure of the liquid in the liquid reservoir chamber to form the discharge portion.
  • the slit discharge portion
  • the slit discharge portion
  • an equal amount of volume of the liquid reservoir chamber to the amount of used liquid is reduced and/or air is invaded into the liquid reservoir chamber through the porous member and the filter.
  • a container body 1 receives therein a soft bag member 3 defining a liquid chamber (liquid reservoir chamber) 2.
  • This soil bag member 3 is an easy means for preventing mixing- in of an ambient air by being contracted in accordance with consumption of the liquid contained therein.
  • the soil bag member 3 is attached to a lower peripheral wall surface of a mouth member 4 by heat sealing, or the like, so that no leakage will occur.
  • the mouth member 4 includes a piston 5 inside thereof.
  • the piston 5 illustrated is attached with another piston element 6 in order to exhibit an appropriate degree of resiliency and ensure a large bore, but it may be an integrally molded product.
  • the piston 5 is attached with a valve 7 which can be opened upwardly in the illustration.
  • the valve 7 serves as an exit of liquid from a hollow interior 8 communicating with the liquid chamber 2.
  • a cylinder 10 biased upwardly in the illustration by a resilient member 9 is slidably attached to the piston 5 in a liquid tight fashion.
  • An elastic annular portion 11, only which is provided on an outer peripheral wall of the piston member 6, serves as a liquid tight slide contact portion with respect to an inner peripheral wall of a hollow interior 12 of the cylinder 10.
  • the cylinder 10 is provided with a valve 13 which can be opened, like the valve 7, upwardly in the illustration. The valve 13 serves as an exit for the liquid coming into the hollow interior 12 from the valve 7.
  • a nozzle member 14 Attached to an upper part of the cylinder 10 is a nozzle member 14, which in the illustrated embodiment includes a liquid passageway 15 for discharging the liquid coming from the valve 13 outside of the container 1 and a crest portion 16 integrally formed on a top portion of the nozzle member 4.
  • the liquid passageway 15 exhibits an L- shaped configuration within the nozzle member 14.
  • a nearby section to an end portion of the liquid passageway 15 which end portion is located on the other side of the valve 13 is in the form of a tube (tubular section 17). That is, a gap 18 is formed between the tubular section 17 of the liquid passageway 15 and the crest portion 16. This gap 18 is circumferentially formed within the nozzle member 14.
  • the elastic valve 19 is fitted onto the tubular section 17 of the liquid passageway 15.
  • the elastic valve 19 comprises a sleeve portion 20 and a bottom portion 21.
  • the sleeve portion 20 is formed on a rear end portion (the other side of the bottom portion 21) thereof with an engagement projection 20.
  • This engagement projection 20a is in abutment with an engagement member 22 which is press- fitted in the gap 18 of the nozzle member 14, or which is integrally formed on the nozzle member 14. Abutment between the engagement projection 20a and the engagement member 22 prevents a possible escape of the elastic valve 19 from the tubular section 17.
  • a slit 21a is formed in the bottom portion 21. This slit 21 is dilated by liquid pressure, so that liquid can be discharged therethrough. This slit 21a serves as a discharge portion of the present invention.
  • the slit 21 may be simply of a linear configuration. It may also be of a reticular or a Y- shaped configuration. A nearby area of a distal end portion of the tubular section 17 is terminated in a reduced- diameter portion 17a. Owing to the foregoing arrangement, the slit 21a can be prevented from being normally dilated by irregularity in the outside diameter dimension of the tubular section 17 and the inside diameter dimension of the elastic valve 19.
  • a gap 23 is formed between the sleeve- like engagement member 22 and the elastic valve 19. This arrangement is employed in order not to interfere the dilation of the slit 21a when liquid is discharged through the slit 21a. By virtue of the above arrangement, the slit 21a can easily be dilated and liquid can be discharged with a reduced force.
  • the elastic valve may include rubber- like elastic members such as a silicon rubber, a nitrile rubber, an acrylic rubber, a fluoro rubber, a natural rubber, a chloroprene rubber, a butyl rubber, a neoprene rubber, an SBR, an NBR, elastomer, and soft polyethylene, and a film- like soil member formed of a single- layer structure such as PET, polyethylene, polyvinyl chloride, or nylon.
  • the film- like soft material may take the form of a two- layer structure obtained by adhering polyethylene to a lower surface of PET, or by adhering polypropylene to a lower surface of PET.
  • the film- like soft material may be obtained by adhering polyethylene to a lower surface of PET coated with vinylidene chloride, polypropylene to a lower surface of PET coated with vinylidene chloride, polyethylene to a lower surface of PET coated with silicon oxide, polypropylene to a lower surface of PET coated with silicon oxide, or by coating a hot- melt resin to a lower surface of PET.
  • the material of the elastic valve can be appropriately selected depending on liquid to be used.
  • the cylinder 10 is caused to slide (return) upwardly in the illustration.
  • the valve 7 is opened to allow liquid to flow out of the hollow interior 8 of the piston 5 into the hollow interior of the cylinder 10 so as to be ready for next operation.
  • the elastic valve is covered with the nozzle member, the crest portion can be depressed without a need of touching the elastic valve. Therefore, the manner of operation is sanitary. In addition, no external force is exerted directly to the elastic valve by depressing operation. As a result, aging deterioration of the elastic valve can be prevented as much as possible.
  • the above is also applicable to the second embodiment to be described hereinafter.
  • FIG. 3 shows the second embodiment of the present invention. Description of the same construction as in the first embodiment is omitted.
  • a nozzle member 26 comprised of a linkage member 24 and a crest portion 25 is attached to an upper part of the cylinder 10.
  • an elastic valve 30 Located on a distal end of the tube member 29 is an elastic valve 30 which is fixed to the tube member 29 by a presser ring 31.
  • a slit 32 which can be dilated by liquid pressure, is formed in a central area of the elastic valve 30. When this sit 32 is dilated, a discharge portion is formed and liquid is allowed to be discharged therethrough.
  • a circular projection 33 is formed on the central portion of the elastic valve 30. Owing to a provision of the circular projection 33, the central portion of the elastic valve 30 is coplanar with a front end face 34a of an inner flange portion 34 of the presser ring 31.
  • the elastic valve 30 is fixedly sandwiched between a distal end face of the tube member 29 and a rear end face 24b of the inner flange portion 34 of the presser ring 31, thus serving as an engagement means of the present invention.
  • An outside diameter of a basal portion of the elastic valve 30 is smaller than an inside diameter of the presser ring 31, while an outside diameter of the projection 33 of the elastic valve 30 is smaller than an inside diameter of the inner flange portion 34. That is, an outer periphery of the elastic valve 30 is opened, so that no external force will be transmitted thereto.
  • the slit 32 can easily be dilated and liquid can be discharged with a reduced force as in the preceding embodiment.
  • the tube member may include metal material such as stainless steel, carbon steel, and copper alloy (phosphor bronze), and material obtained by coating resin such as polyamide, vinyl chloride, polyethylene, and polyurethane to the surface of those metal material, or a resin molded product such as POM, ABS, PP, PET and PE.
  • metal material such as stainless steel, carbon steel, and copper alloy (phosphor bronze)
  • resin such as polyamide, vinyl chloride, polyethylene, and polyurethane
  • resin molded product such as POM, ABS, PP, PET and PE.
  • the resilient member 9 is disposed outside the hollow interior 12 of the resilient member 9. By preventing the resilient member 9 from contacting the liquid, contamination of the liquid caused by rust is prevented.
  • Fig. 4 shows an example in which the presser ring 31 in the second embodiment is not used in order to achieve cost down.
  • the elastic valve 35 includes a sleeve portion 36 and a bottom portion 37 as in the first example.
  • an enlarged- diameter portion 36a is formed on an outer peripheral surface of the sleeve portion 36 and a circumferential rib 36b is formed on an inner peripheral surface portion.
  • An inner peripheral flange portion 37 subjected to be abutment with a front end face of the enlarged- diameter portion 36a of the sleeve portion 36 is formed on the rest portion 25. Owing to this arrangement, the elastic valve 29 is prevented from being escaped from the tube member 29 when an excessive liquid pressure occurs.
  • a front end face of the enlarged- diameter portion 36a is not in abutment with the inner peripheral flange portion 37. In doing so, opening and closing of the slit 38, through which liquid is discharged, is not disturbed. However, the elastic valve 35 and the tube member 29 are prevented from being escaped through engagement between the circumferential rib 36b and a circumferential recess 39 formed in an outer periphery of the tube member 29.
  • the nozzle member and the elastic valve of the first and second examples may be attached to the discharge portion of the previously mentioned conventional container.
  • a soft porous member 40 is disposed beneath the cylinder 10 (nozzle member 14) according to the first embodiment.
  • the resistive force of the porous member 40 is also added to the resistive force when the pressing operation is performed.
  • the resistance means is a porous member such as a sponge.
  • the beneath part of the resilient member may be of dense spiral structure. The pressing force becomes larger at an intermediate stage of the pressing operation rather than at the start of the depressing operation. Due to this function, the downward moving speed of the nozzle member is decreased. By utilizing this phenomenon, liquid is prevented from being abruptly discharged from the slit 21a of the elastic valve 19.
  • the resilient member 9 is disposed outside the hollow interior 12. Owing to this arrangement, contamination of the liquid caused by rust or the like when the resilient member 9 is made of metal is prevented.
  • a container body 41 receives therein a soft bag member 43 within which a liquid chamber (liquid reservoir chamber) 42 is defined.
  • This soil bag member 43 is attached to a lower peripheral wall surface of a mouth member 44 attached to an opening portion of the container body 41 by heat sealing, or the like, so that no leakage will occur.
  • the mouth member 44 is a sleeve- like member having a bottom portion 45. Formed in a central portion of the bottom portion 45 is a hollow interior 46 which is in communication with the liquid chamber 42.
  • a first valve 47 capable of opening upwardly in the illustration is attached to the hollow interior 6.
  • the first valve 47 comprises a fixed ring portion 47a to be fixed to the bottom portion 45 of the mouth member 44, a valve portion 47b, and three arcuate leg portions 47c for separatably/restorably interlinking the fixed ring portion 47a and the valve portion 47b, so that it can easily be actuated even by liquid having low viscosity (see Fig. 7).
  • the valve portion 47b of the first valve 47 serves as a substantial exist for the liquid from the liquid chamber 42.
  • the mouth member 44 is slidably attached with a nozzle member 48 with its lower part embedded in the mouth member 44 and with its upper part projected from the mouth member 44.
  • a liquid passageway 49 is formed, one end portion of which is served as a tubular discharge port 50 through which liquid is discharged.
  • the discharge port 50 is slidably attached with a second valve 52 (see Figs. 8 and 9) having a slit 51 formed in a lower part of its distal end and serving as a final discharge portion for liquid.
  • a presser ring 53 is disposed in front of the second valve 52 in such a way to cover the second valve 52.
  • the presser ring 53 is fixed to the nozzle member 48.
  • doglegged hinge portions 54 are formed on vertically corresponding locations (see Fig. 10).
  • the second valve 52 is biased backwardly by the hinge portions 54.
  • Reference numeral 55 denotes a flange portion formed on a rear end of the second valve 52. Rear ends of the hinge portions 54 are in abutment with the flange portion 55.
  • Examples of the material of the second valve 52 may include the same rubber- like elastic members as in the elastic valve of the preceding embodiment, such as a silicon rubber, a nitrile rubber, an acrylic rubber, a fluoro rubber, a natural rubber, a chloroprene rubber, a butyl rubber, a neoprene rubber, a SBR, an NBR, elastomer, and soft polyethylene.
  • a silicon rubber such as a silicon rubber, a nitrile rubber, an acrylic rubber, a fluoro rubber, a natural rubber, a chloroprene rubber, a butyl rubber, a neoprene rubber, a SBR, an NBR, elastomer, and soft polyethylene.
  • an expansible sleeve- like bellows member 56 is fixed to the other end side of the liquid passageway 49 of the nozzle member 48, while the other end of the bellows member 56 is fixed such that the first valve 47 is placed within the hollow interior 46 of the mouth member 44.
  • the bellows member 56 is expansible and has an elastic property.
  • the nozzle member 48 is biased upwardly by the bellows member 56. That is, when the nozzle member 48 is depressed downwardly, the bellows member 56 is contracted and when the depression is canceled, the bellows member 56 is stretched (returned to its initial position) by its own elastic force.
  • the bellows member 56 is fixed to the nozzle member 48 and the mouth member 44 through male- and- female engagement for the sake of easy assembly. Depending on viscosity of the liquid, however, they may be fixed by other fixing means such as bonding or welding, so that sealability and escape preventability can be enhanced.
  • Examples of the material of the bellows member may include rubber- like elastic members such as a silicon rubber, a nitrile rubber, an acrylic rubber, a fluoro rubber, a natural rubber, a chloroprene rubber, a butyl rubber, a neoprene rubber, a SBR, an NBR, elastomer, and soft polyethylene, and a soft member formed of a single- layer structure such as PET, polyethylene, polyvinyl chloride, or nylon.
  • the soft material may take the form of a two- layer structure obtained by adhering polyethylene to a lower surface of PET, or by adhering polypropylene to a lower surface of PET.
  • the soft material may be obtained by adhering polyethylene to a lower surface of PET coated with vinylidene chloride, polypropylene to a lower surface of PET coated with vinylidene chloride, polyethylene to a lower surface of PET coated with silicon oxide, polypropylene to a lower surface of PET coated with silicon oxide, or by coating a hot- melt resin to a lower surface of PET.
  • the bellows member 56 Upon depression of the nozzle member 48, the bellows member 56 is contracted downwardly in the illustration against its own elastic force. As a result, the liquid within the bellows member 56 and the liquid passageway 49 is pressurized. This causes the second valve 52 to proceed forwardly against the resilient force of the hinge portions 54 of the presser ring 53. As a result, the slit 51 of the second valve 52 is exposed. At that time, the slit 51 is slightly dilated by pressure of the liquid to allow the liquid to be discharged (see Fig. 11: in this illustration, the amount of dilation of the slit of the second valve is shown in a somewhat exaggerated manner).
  • the bellows member 56 When the depression to the nozzle member 48 is canceled here, the bellows member 56 is stretched by its own restoring force and the inside pressure of the bellows member 56 becomes negative. This, together with the elastic force of the hinge portions 54, causes the second valve 52 to be retracted and covered again with the presser ring 53. Further, since the pressure of the liquid is reduced, the slit 51 is also closed. The closing action of the slit 51 is sometimes performed immediately before retraction of the second valve 52. Occasionally, the slit 51 is slowly closed after the second valve 52 is retracted. This depends on viscosity of the liquid to be used, the resilient force of the bellows member 56, and some other factors of a similar nature.

Moreover, since no external force is applied to the second valve 52 which would otherwise be applied thereto by depressing operation, aging deterioration can be prevented as much as possible.
