Definitions

  • the present invention relates to a flow rate regulator unit or the like for aerosol containers from each of which a content therein is sprayed to an external space with the aid of the action of discharge gas (compressed gas, liquefied gas).
  • discharge gas compressed gas, liquefied gas
  • the present invention concerns a flow rate regulator unit mounted for use between a housing for a stem equipped with a content passing hole part, opened and closed in response to the operation of a user, and with a passageway part extending to a downstream side of the hole part and a suction pipe for the content in the container, for stabilizing a flow rate of the content sprayed from the aerosol container to the external space by making use of the action of discharge gas in the container.
  • the present invention also concerns a flow rate regulator mechanism for communicating a moving air compression region of a flow rate stabilizing member for changing a content passing space in the housing and an external space via an air passageway or the like formed in the stem.
  • the flow rate regulator unit and the flow rate regulator mechanism are to prevent an amount of a sprayed content per unit time to an external space from sharply varying even in any of cases where pressure of compressed gas in a container body at an early stage of the use for example is high or where the pressure in the container body is lowered owing to its use thereafter.
  • the pressure of liquefied gas is prevented from lowering in response to the degree of the use , but the pressure changes depending on the temperature of a use environment.
  • the present invention is to fulfill such.
  • the present invention is to further improve this property and to make the flow rate regulator a unit structure independent from other constituent elements (operation button, housing or the like) of an aerosol container, which is to be mounted on a inlet side of the suction pipe mounting part of a housing, i.e., on a rigid passageway region, which prevents content passageways being deformed and inflected (unlike the suction pipe).
  • the present invention is to simplify a regulator assembly work where a unit type flow rate regulator may be mounted between the housing and the suction pipe as well as to stable the spray of a content in a container by supplying the content controlled by the flow rate regulator up to the discharge hole through respective internal passageway regions of the housing, stem and operation button with no danger of deformation and inflection.
  • the present invention is to make compact the flow rate regulator mechanism itself by communicating the moving air compression region of the flow rate stabilizing member where the content passing space in the housing changes with the external space, and hereby surely avoid an air compression problem accompanying the movement of the flow rate stabilizing member.
  • the present invention solves the aforementioned problems in the following ways:
  • the flow rate regulator unit is constituted as a unit structure in such a way that it is fixedly mounted on a suction pipe mounting part of the aerosol container on a housing inlet side and mounted on the suction pipe, so that it is possible to simplify an assembly work of the flow rate regulator itself.
  • the suction pipe that might be deformed and inflected is incorporated or removed from the passageway part extending from the flow rate regulator to the discharge hole, so that it is possible to stably inject a container content.
  • the moving air compression region of the flow rate stabilizing member for changing the content passing space by the movement based on the gas pressure in the container and on predetermined elastic force communicates with the external space, so that it is possible to surely avoid an air compression problem accompanying the movement of the flow rate stabilizing member even if the air compression region has small capacity and make compact the flow rate regulator mechanism itself.
  • each constituent element with a reference number having any letter of the alphabet is a part of the constituent element with the reference number not having any letter of the alphabet (e.g., cylinder 11).
  • the first principal feature of the present invention is that a flow rate regulator is provided in a demountable unit style which can be equipped between the housing and the suction pipe of the aerosol container, entirely different from the conventional manner where a regulator is formed in any of the essential elements of the container, such as a discharge head (or operation button), a stem, a housing, or a suction pipe.
  • a flow rate regulator is provided in a demountable unit style which can be equipped between the housing and the suction pipe of the aerosol container, entirely different from the conventional manner where a regulator is formed in any of the essential elements of the container, such as a discharge head (or operation button), a stem, a housing, or a suction pipe.
  • the second principal feature (refer to FIGs.7, 8) of the present invention is as follows:
  • the moving air compression region of the flow rate stabilizing member for changing the content passing space by the movement of the member based on the gas pressure in the container and predetermined elastic force is made to communicate with an external space.
  • the constituent elements of the flow rate regulator units 10, 20, 30 and the flow rate regulator mechanism 50 are made of plastic such as polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, etc.
  • the coiled springs 15, 25, 35, 57, 62 are made of stainless or plastic.
  • Materials of the stem gasket 64 and the annular rubber 65 are acrylonitrile-butadiene rubber(NBR), Butyl-rubber(IIR), and other rubber-made sealing members.
  • Material of the mounting cap 66 is tin or an aluminum material.
  • coiled springs 15, 25, 35, 57, 62 there may be used arbitrary elastic members such as various types of springs and leaf springs.
  • the present invention employs both of compressed gas and liquefied gas as the content discharge gas as described above, in the following the compressed gas will be employed for brevity of the description.
  • An inner cylinder 12 of a flow rate regulator unit 10 illustrated in FIGs.1 and 2 has an elongation section 12c for fitting over a small diameter section 41a of an existing housing 41.
  • a cylinder 11 for forming a content passageway between it and the inner cylinder 12 has a cylindrical suspension part 11 a for mounting an existing suction pipe 42.
  • the inner cylinder 12 contains a piston 13 energized downward with a coiled spring 15 and a flow rate adjusting valve 14 fitted to and united with the piston 13.
  • an upper inlet part A in space regions for passageway to the housing 41 is set to a substantially closed state or a narrow state by the flow rate adjusting valve 14, in which the content flow route is designed to follow in the order of suction pipe 42, the space region formed by groove parts for passage of a content 16a, -a space region between inner annular surface of a cylinder 11 and an outer annular surface of an inner cylinder 12, a horizontal hole 12a, the upper inlet part A, groove part 12b, a space region between a flow rate adjusting valve 14 and a lower cover 16, passageway 13a of a piston 13.
  • a content passing hole part in a stem (not shown) following the passageway space region is closed with a well known stem gasket to bring pressure in the passageway space region to the same high pressure (compared with the atmospheric pressure) as in the interior of the container.
  • the high pressure acts on a wide lower surface part 14b of the flow rate adjusting valve 14 to push up the flow rate adjusting valve and the piton 13 against the energizing force of the coiled spring 15.
  • the content passing hole part of the stem changes from the so far closed state to an open state.
  • the stem hole part By opening of the stem hole part, the content existent in a downstream passageway space region lower than the upper inlet part A (nearly equal to a part of the passageway space region + housing 41) is discharged to the external space through the passageway part in the stem.
  • time of the transition from FIG. 1 to FIG. 2 (the total timing of the substantially closed state of the upper side inlet part A) is a so-called constant that is mainly determined by the energizing force of the coiled spring 15 and in contrast timing of the opposite transition from FIG. 2 to FIG. 1 (the total time of the open states of the upper side inlet part A) is a so-called variable based on gas pressure.
  • the flow rate adjusting valve 14 has larger driving force (the foregoing gas pressure) to push the valve position as shown in FIG.2 to that in FIG.1 so that the number of times of up and down movements of the flow rate adjusting valve per unit time is also larger (i.e., the total time of the substantially closed state of the upper side inlet part A is long; and when pressure of the compression gas becomes lower owing to the discharge operation of the content, the foregoing driving force is also reduced so that the number of times of the up and down movements of the flow rate adjusting valve 14 per unit time becomes small (i.e., the total time of the substantially closed states of the upper side inlet part A is short).
  • a substantially closed state time interval t1 (continuation time in FIG.1) of the upper side inlet part A per one time of the up and down movement is a substantially constant value based on the energizing force of the coiled spring 15, and in contrast an open state time interval t2 (continuation time in FIG.2) per one time is shorter as gas pressure in the container body becomes higher.
  • a time fraction that the inlet part A, which is a part of the content passageway, becomes the open state, is smaller as the pressure of the gas is higher like the compressed gas in an early time of use.
  • the open state time per unit time is shorter than in the low pressure gas state.
  • the substantially closed state time interval t1 made substantially constant irrespective of the gas pressure in the aforementioned description, when the upper side inlet part A of FIG.1 changes to a wide state of FIG.2, is qualitatively related to a time interval where pressure acting, till then, on the lower surface part 14b of the flow rate adjusting valve 14, lowers to a predetermined value corresponding to the energizing force of the coiled spring 15, so that it is more lengthened as the pressure (gas pressure in the container) is higher.
  • a flow rate regulator unit 20 illustrated in FIGs.3 and 4 includes a connection member 26 for integrating a cylinder 21 and a sheath-shaped part 22 or the like and fitting it over a small diameter part 41a of the housing 41.
  • the cylinder 21 includes a cylindrical suspension part 21a for mounting a suction pipe 42, and the sheath-shaped part 22 contains the piston 23 energized upward by the coiled spring 25 and the flow rate adjusting valve 24 fitted to the piston.
  • an inlet part B of the passageway space region leading to the housing 41 from the internal space of the container body (not shown) and the suction pipe 42 is set to a substantially closed state or a narrowed state by the flow rate adjusting valve 24 more specifically, in such as route as " between leaves 22c-a space region between the cylinder 21 and the sheath part 22-a horizontal hole 22a-the inlet part B-a groove part 22b-a space region between the connection member 26 and the upper surface side part 24b of the flow rate adjusting valve 24-a slit 26b of the connection member 26.
  • the reason is as follows:
  • the content passage hole part of the stem following the passage space region is closed with a well known stem gasket so that pressure in the passage space region is high (compared with the atmospheric pressure), similar to the inside of the container. More specifically, the high pressure acts on the upper surface 23a of the piston 23 or the like to press down the piston and the flow rate adjusting valve 24 against the energizing force of the coiled spring 25.
  • the content passing hole part of the stem changes from the closed state so far to the opened state.
  • the stem hole part By opening of the stem hole part the content existent in the passageway space region ( ⁇ a part of the foregoing passageway space region + housing 41) on a downstream side from the lower inlet part B before that, is discharged to an external space via the passageway of the stem.
  • the change of the inlet part B to the opened state causes the container inside and the external space to be communicated via the aforementioned passageway space region and the stem hole part, the container content being hereby discharged to the external space.
  • a time interval when the inlet part B in FIG.3 changes to a wide state in FIG.4 relates to a time interval when the pressure acting, till then, on the upper surface 23a of the piston 23 lowers to a predetermined value corresponding to the energizing force of the coiled spring 25 and is hence prolonged as the pressure is high.
  • a cylinder 31 of a flow rate regulator unit 30 illustrated in FIGs.5 and 6 includes a cylindrical elongation part 31a for fitting over the small diameter part 41a of the housing 41.
  • the cylinder 31 includes a joint 37 attached thereto for mounting the suction pipe 42 and contains therein a piston 33 energized downward by the coiled spring 35, a flow rate adjusting valve 34, and a bush 36 that forms an inlet part C between lower surface part 36 and the flow rate adjusting valve.
  • the joint 37 includes in its internal space a flow receiving part 37b for suppressing the force of a content flowing in from the suction pipe 42 upstream the flow rate adjusting valve 34.
  • the reason is as follows:
  • the content passing hole part of the stem (not shown) adjacent to the passageway space region is closed with a well known stem gasket to make the pressure in the passageway space region the same high pressure (compared with the atmospheric pressure) as in the container. More specifically, the high pressure acts on the lower surface part 33b of the piston 33 to push up the piston and the flow rate adjusting valve 34 against the coiled spring 35.
  • the content passing hole part of the stem changes its state from a so far closed state to an open state.
  • a flow rate of a content per unit time discharged to the external space is stabilized with respect to a change in the gas pressure by further reducing a ratio of time which the inlet part C is the open state per unit time (ratio of passable time of the content)in FIG.6 for the high gas pressure in the container than the case at the time of the low pressure.
  • an air upper space region 58 and an air lower space region 59 in the housing which change self volumes in response to the movement of "a piston 55 + a flow rate adjusting valve 56" for a flow rate regulator are communicated to the external space by an upstream side air passageway 61c of a stem 61 and a downstream side space region 60b of an operation button 60 respectively
  • the upstream side air passageway 61c may be formed to open toward a stem's outer peripheral surface located between a mounting cap 66 and an operation button 60 at its output side. In this case, the downstream side air passageway 60b of the operation button 60 is unnecessary Further, the upstream side air passageway is an air exclusive passageway, different from the content injecting passageway.
  • the flow rate regulator mechanism 50 substantially comprises:
  • Tip end parts of the reverse skirt-shaped part 55a of the piston 55 and of the lower skirt-shaped part 56a of the flow rate adjusting valve 56 make close contact with the internal peripheral surface of the lower receiving part 53 (other than the horizontal hole 53a for the flow rate regulator), and a tip end part of the upper skirt-shaped part 56b of the flow rate adjusting valve 56 makes contact with the internal peripheral surface of the upper reception part 54.
  • an air reservoir space in a kind, of the air upper space region 58, internal passageway 55b, and lower air space region 59 is communicated to the external space in an air exclusive passageway mode sealed from the content injection passageway (refer to FIG.8).
  • the content injection passageway extending from the suction pipe 42 to the external space substantially consists of "vertical hole 51a of the lower housing part 51-horizontal groove-shaped part of the rib 51b-horizontal hole 53a-inlet part D-space region between the flow rate adjusting valve 56 and the lower receiving part 53-horizontal hole 54a-space region between the upper receiving part 54 and the lower housing part 51-penetration part 52b-buffer space 63-horizontal hole 61a-annular passageway 61b-longitudinal passageway 60a".
  • the inlet part D in the content injection passageway is set to a substantially closed state or a narrow state by the flow rate adjusting valve 56.
  • the horizontal hole 61a of the stem 61 constituting the injection passageway is closed by the well known stem gasket 64, and so pressure in the injection passageway located downstream the horizontal hole is the same high pressure as that in the container. More specifically, the high pressure acts on the annular ceiling surface 56c of the flow rate adjusting valve 56 (and the piston 55) or the like to push up the flow rate adjusting valve against the energizing force of the coiled spring 57.
  • An upward movement range of the flow rate adjusting valve 56 is limited by a protruded part formed on a ceiling surface edge of the upper receiving part 54.
  • the operation button 60 When a user presses the operation button 60 to set the operation to the actuation mode (refer to FIG.8), the content passing horizontal hole 61 a of the stem 61 changes its state from the so far closed state to the open state.
  • the content in the injection passageway located so far on a just upstream side of the horizontal hole e.g., a passageway region from the horizontal hole 61a to the inlet part D
  • the content in the injection passageway located so far on a just upstream side of the horizontal hole e.g., a passageway region from the horizontal hole 61a to the inlet part D
  • the annular passageway 61b and the longitudinal content injection passageway 60a By opening of the stem's horizontal hole, the content in the injection passageway located so far on a just upstream side of the horizontal hole (e.g., a passageway region from the horizontal hole 61a to the inlet part D) is discharged to the external space via the annular passageway 61b and the longitudinal content injection passageway 60a.
