Definitions

  • This invention relates to a sprayer, more particularly to an air-pressurized sprayer in which air in a container is pressurized in advance by a pump.
  • Aerosol-type sprayers are well-known sprayers which are advantaged in being capable of continuously spraying a full pressurized liquid and in the ease of handling or operation.
  • Containing high-pressure gas such as Freon gas
  • a liquid container used in one such sprayer need be a pressure-resisting container such as a metal can.
  • Freon gas which is generally used as the high-pressure gas to be jetted together with a liquid, may cause air pollution.
  • manual sprayers represented by trigger type or push-button type sprayers pressurize and spray a liquid by a pumping action caused by a swing of a trigger or a descent of a push button without the assistance of any high-pressure gas. Accordingly, these sprayers need no pressure-resisting container, and will never cause air pollution. With the conventional manual sprayers, however, the liquid is pressurized and sprayed with every pumping action. Further, the spraying condition is closely related to the pressurizing force, so that a great pressure need always be applied to obtain highly minute particles of liquid for spraying. For continuous spraying, moreover, the pumping action need be repeated.
  • air-pressurized sprayers in which high-pressure air is accumulated in advance in a container by sliding a piston.
  • a nozzle is lowered not for a pumping operation but only to open a valve for spraying.
  • a liquid in the container is pressed by highly pressurized air in the container, and is continuously sprayed in the form of minute particles through the spraying valve.
  • the piston is locked to a position where it is fully in during a spraying operation.
  • a prior art air-pressurized sprayer is provided with an air intake which is closed during the pumping operation and, on completion of the pumping operation, is connected with the atmosphere to discharge the residual high-pressure air within the cylinder into the atmosphere, thereby removing the resisting force against the locking action of the piston.
  • the air intake need be entirely blocked during the pumping operation, and also the closed state of the air intake must be maintained while applying large pushing force against the residual high-pressure air, thus complicating the pumping operation.
  • a cylinder is attached to the bottom portion of the container, and a piston is slidden inside the cylinder to pressurize air therein.
  • the pressurized air is supplied from the cylinder to the container through a value.
  • An air-pressurized sprayer 10 according to a preferred embodiment of the invention, as shown in Fig. 1, includes a valve housing 14 attached to the top portion of a container 12 made from plastic, and a cylinder 16 attached to the bottom portion of the container.
  • the number of components can be reduced to facilitate construction by integrally forming the valve housing 14 with the container 12, as shown in Fig. 1.
  • the valve housing 14 contains a one-way valve 18 for spraying which includes a plastic stem 20, a rubber gasket 22 capable of blocking a lateral hole 21 of the stem, and a compression coil spring 24.
  • the spraying valve 18 is received in the valve housing 14 with a fixing ring 26 screwed in an internally threaded portion of the valve housing.
  • the stem 20 of the spraying valve 18 is fitted in a passage 30 formed inside a push button 28 which is located within a recess 27 (see Fig. 2) at the top portion of the container 12.
  • the push button 28 is formed integrally with a nozzle 29.
  • the spraying valve 18 may be constructed by integrally forming the stem and compression spring. Such construction leads to a reduction in the number of components and hence to an improvement in the ease of assembling.
  • the container 12 is provided with an integral level bar 32 extending downward from the top portion thereof.
  • the level bar 32 functions as a standard for the level of the liquid which is supplied to the container 12 turned upside down, as mentioned later.
  • the cylinder 16 is screwed in the bottom portion of the container 12 to extend thereinto.
  • the cylinder 16 has integrally formed inner and outer walls 36 and 38, the inner wall 36 being screwed in the lower end portion of the container 12 so that the lower end portion of the container is held between the inner and outer walls 36 and 38.
  • An 0-ring 40 is interposed between the cylinder 16 and the container 12 to secure liquid-tightness between them. Since the lower end portion of the container 12 is thus held between the inner and outer walls 36 and 38 of the cylinder 16, the engagement between the cylinder and the container 12 may be secure enough to prevent leakage of the liquid even under high pressure. Also, the cylinder 16 may be removably attached to the bottom portion of the container 12 by any other means than screwing.
  • the cylinder 16 has a valve 42 for air pressurization at the inner end thereof.
  • the pressurization valve 42 is a one-way valve which allows only a current of air into the container 12, including a valve plug 48 coupled to a valve body 44 by three rocking strips 46 (see Fig. 5) and capable of moving along the axial direction.
  • a hollow piston 54 is contained in the cylinder 16 so as to be slide inside the cylinder.
  • the piston 54 includes a pair of pistons 60 and 61 respectively having one-way valves 58 and 59 for air suction which allow air to flow into a pressure chamber 56 defined between the cylinder 16 and the piston.
  • the piston 61 is smaller in diameter than the piston 60, and the former is slidably contained in the-latter.
  • these one-way valves 58 and 59 are each composed of a valve body and a valve plug coupled thereto by rocking strips.
  • the large-diameter piston 60 has a number of air intakes 64, and can be locked to the cylinder 16 by a locking means 66.
  • the locking means 66 need only be able to lock the piston body 54 to the cylinder 16 or the container 12 at the spraying operation of the sprayer 10, and may be of various constructions without being limited to the construction of Fig. 1 in which an engaging projection 70 formed on the outer wall 38 of the cylinder is caused to engage an engaging hole 68 formed in the large-diameter piston 60.
  • the air-pressurized sprayer 10 of the-above-mentioned construction is operated as folows.
  • the container 12 is turned upside down, and the cylinder 16 is rotated to be released from the engagement with the container 12 and then removed together with the piston 54 from the container 12. Entirely contained in the recess 27 at the top portion of the container 12, the push button 28 will never be pressed even though the container is inverted.
  • the liquid is supplied into the container 12 to, for example, the tip end of the level bar 32.
  • the valve housing 14 and the cylinder 16 are attached respectiveely to the top and bottom portions of the container 12 so that they are separated completely.
  • the supply of the liquid requires only that the cylinder 16 be removed from the container 12, and it is quite unnecessary to disassembly the valve housing 14.
  • the cylinder 16 is screwed again into the container 12.
  • the lock is released, and the piston 54 is slidden within the cylinder 16.
  • the large-diameter piston 60 of the piston 54 is reciprocated in one with the small-diameter piston 61 as the latter is kept contained in the former. Air is sucked in through the air intakes 64, and distorts a skirtlike seal of the piston 60 to flow into the pressure chamber 56.
  • the air flows into the pressure chamber 56 also through the air suction valves 58 and 59.
  • the air inside the pressure chamber 56 is pressurized by a pumping action caused by the reciprocation of the piston 54 or the large-diameter piston 60, and flows through the accumulation valve 42 into the container 12 to be accumulated therein.
  • the high-pressure air inside the container 12 acts as resistance force on the large-diameter piston 60 to prevent smooth reciprocation of the piston. Since having the smaller diameter than that of the large-diameter piston 60, the small-diameter piston 61 can slide without substantially suffering the resistance force of the high-pressure air.
  • the sprayer of the invention comprises an airtightness release means 74 formed in the inner wall of the cylinder 16 between a forced-in position 72 of the piston 54 for pumping operation as indicated by a one-dot chain line and the lock position as illustrated.
  • the airtightness release means 74 is formed of, for example, a groove 76 as shown in Fig. 6.
  • a seal 78 of the large-diameter piston 60 reciprocates within a range or region below the forced-in position 72, so that the airtightness of the piston 54 or the large-diameter piston 60 may be maintained effectively.
  • the piston 54 is pushed in beyond the forced-in position 72 to have its seal 78 fitted in the groove 76, so that a gap 80 (see Fig. 7A) is created between the seal 78 and the inner wall of the cylinder 16.
  • the airtightness release means 74 need only have a function to release the airtight relationship between the seal 78 and the inner wall of the cylinder 16.
  • the airtightness release means 74 is not limited to the configuration of the entirely circular groove, and may be provided with a number of, e.g. four, projections 82 as shown :'.n Fig. 7B.
  • the seal 78 preferably has a groove 84 is which a lubricant can stay.
  • the groove 84 is not limited to the entirely circular groove as shown in Fig. 8, and may alternatively be formed of a number of partial grooves or small recesses. Further, the skirtlike seal 78 may be replaced with an O-ring.
  • the small-diameter piston 61 is provided with another airtightness release means 174 including a groove 176 which is formed in the inner wall of the large-diameter piston 60 between a forced-in position 172 as indicated by a one-dot chain line and a lock position as illustrated.
  • a seal 178 of the small-diameter piston 61 also has a groove 184 for retaining the lubricant.
  • the airtightness release means 174 of the small-diameter piston 61 has the same function as the airtightness release means 74 of the large-diameter piston 60, thereby facilitating the thrusting of the small-diameter piston 61 into the lock position.
  • the air is fully pressurized by the small-diameter piston 61, and the small-diameter piston 61 is forced into its lock position.
  • the container 12 is restored to its right position and the push button 28 is lowered inside the recess 27, the blocking of the lateral hole 21 of the stem 20 by the gasket 22 is released, and the liquid pressed by the pressurized air accumulated in the container 12 rises in the pipe 31 and is continuously discharged from the nozzle into the outside through the lateral hole 21 and passage 30.
  • FIG. 9 shows another embodiment of the invention.
  • This air-pressurized sprayer 110 differs from the sprayer 10 in that a container 12 is formed integrally with a cylinder 16, and that a cover section 13 integrally formed with a valve housing 14 is welded to the container. Instead of welding, the cover section 13 may be screwed into the container 12.
  • a locking means 66 between a cylinder 16 integrally formed with the container 12 and a large-diameter piston 60 is so designed that an engaging projection 70 formed.at the lower end of the container 12 may be fitted in an engaging hole 68 formed in the large-diameter piston 60. Since the container 12 and the cylinder 16 are formed integrally, the sprayer 110 is improved in liquid-tightness.
  • the container used in this invention need not be a pressure-resisting container such as a conventional metal can used for an aerosol sprayer. It is to be understood, however, that pressure-resisting containers of such type can suitably be used.
  • Fig. 10 shows an embodiment using one such conventional pressure-resisting container.
  • This sprayer 210 includes a pressure-resisting metal container 212 which is characterized by its vertical symmetry and by having a steel cover 213 at the lower end, too.
  • a valve housing is fixed to a steel cover (not shown) at the upper end of the aprayer 210 by a clamping ring, while a cylinder 216 is fixed to the lower-end steel cover 213 by a clamping ring 217.
  • Numeral 219 designates a plug for liquid supply.
  • the sprayer 210 including the pressure-resisting metal container 212 thus formed in the vertically symmetrical configuration, the manufacturing cost of the die for the container is reduced, and the assembly is facilitated. With such construction, moreover, the sprayer may be high in pressure resistance, and the greater-part of the conventional pressure-resisting metal container may be utilized directly.
  • a piston 54 has on its outer surface projections 221 which press the clamping ring 217 toward the cylinder 216: Although four projections 221 are equiangularly arranged in this embodiment, at least one projection will suffice. Substantially U-shaped notches 223 surrounding the projections 221 are formed on the outside of the piston 54. In such construction, the projections 221 are pressed against the clamping ring 217 with sufficient elasticity due to the existence of the notches 223. Thus, the clamping ring 217 can securely hold the cylinder 216 between itself and the steel cover 213.
  • Fig. 12 shows another embodiment utilizing a pressure-resisting metal container.
  • a cylinder 316 is attached to a steel cover 313 by a plastic clamping member 317 which is outsert-formed on the steel cover 313.
  • the clamping member 317 is provided with an internal-thread portion 319 in which an external-thread portion 321 formed on the outside of the' cylinder 316 is screwed so that the cylinder is fixed to the steel cover 313.
  • the clamping member 317 has a downwardly projected seal 323 which abuts on an inner surface 325 of the cylinder 316 to secure liquid-tightness.
  • clamping member 317 and the cylinder 316 are removably connected by screwing in the embodiment of Fig. 12, they may be removably connected by any other suitable means.
  • the projected seal 323 may be replaced with any other seal member, such as a skirt-like seal.
  • Numerals 327 and 329 designate a plurality of reinforcing ribs formed on the cylinder 316 and a piston 354, respectively.
  • the sprayer 310 capable of easy assembly and easy liquid supply may be provided by outsert-forming on the steel cover 313 the clamping member 317 which includes the means removably connected to the cylinder 316 and the seal member for liquid-tightness. Further, the integral formation of the clamping member 317 and the steel cover 313 can completely prevent the loss of the clamping member 317 during the liquid supply.
  • a one-way valve 142 for air pressurization as shown in Figs. 13 and 14 may be used in the cylinder instead of using the one-way valve 42 as shown in Fig. 5A.
  • the rocking strips 46 of the valve 42 extend in a flat manner, whereas rocking strips 146 of the valve 142 extend axially or in three dimensions. Therefore, a valve plug 48 of the valve 142 can be enabled to produce sufficient axial biasing force by attaching a valve body 144 of the valve 142 to the tip end of the piston with the valve plug 48 pressing on the valve seat. Accordingly, the valve 142 can have enough resistance force against the air inside the pressure chamber 56, ensuring reliable valve action.
  • a child-proof mechanism 150 includes a stopper 154 which is formed integrally with the push button 28 through a hinge 152.
  • a rectangular recess 156 for containing the stopper 154 is formed in the peripheral surface of the container 12.
  • the recess 156 has a shoulder portion 158 against which e.g. the free end of the stopper 154 abuts.
  • a dent 160 in the shape of e.g.
  • a subsphere is formed in the surface of-the recess 156 so that a gap is created between the back side of the stopper 154 and the peripheral surface of the container 12 when the dent is partially covered with the free end portion of the stopper.
  • Numeral 162 designates a dent formed on the top of the push button 28 for smooth location of an operator's finger.
  • the push button 28 can be prevented from descending by the engagement between the shoulder portion 158 and the free end of the push button even if the push button is pressed.
  • unexpected depression of the push button 28 can be avoided even during storage as well as during packing and exhibition.
  • the engagement between the stopper 154 and the shoulder portion 158 of the recess 156 can easily be released by swinging the stopper 154 around the hinge 152, as indicated by a one-dot chain line in Fig. 16. By such release of the engagement, the push button 28 is allowed to descend, and the desired spraying operation can be performed with ease by depressing the push button 28 as required.
  • the existence of the dent 160 facilitates the swing of the stopper 154.
  • the shoulder portion 158 of the recess 156 need only have a function to prevent the push button 28 from descending, and is not limited to the arrangement of Figs. 15 and 16 in which it abuts against the free end of the push button 28.
  • an engaging projection 164 may be projected from the back of the stopper 154 so that the shoulder portion 158 can engage the projection 164.
  • the dent 160 may be formed greater, so that the stopper 154 can be swung more smoothly.
  • Figs. 19 to 22 show another child-proof mechanism 170 which includes a seesaw-type stopper 174 formed integrally with the push button 28 through a pair of connection pieces 172.
  • a recess 178 Formed in the peripheral surface of the container 12 is a recess 178 having a shoulder portion 176 against which e.g. the tip end portion of the stopper 174 abuts.
  • the push button 28 is prevented from descending by the engagement between the shoulder portion 176 of the recess 178 and the stopper 174 even if the push button 28 is pressed.
  • the engagement between the stopper 174 and the shoulder portion 176 can easily be released by swinging the stopper 174 in the counterclockwise direction around the connecting pieces 172, as indicated by a one-dot chain line in F ig. 22. By such release of the engagement, the push button 28 is allowed to descend, and the desired spraying operation can be performed with ease by depressing the push button 28 as required.
  • a pair of engaging projections 182 each having e.g. a sub- circular cross section are formed on the distal end portion of the stopper 174, and engaging holes 184 to engage the projections 182 are formed in the shoulder portion 176.
  • Such combination of the engaging projections 182 and the engaging holes 184 can ensure full engagement between the stopper 174 and the shoulder portion 176 during storage, thereby positively preventing unexpected depression of the push button 28.
  • a stopper extending along the direction to press the push button is formed integrally with the push button, and a recess containing the stopper and having a shoulder portion to engage the stopper is formed in the peripheral surface of the container.
  • the push button can be repeatedly brought to the undescendable or locked state to prevent accidents during storage. It is to be understood that the child-proof mechanism of this type can be applied not only to air-pressurized sprayers but also to aerosol-type sprayers.
  • a valve housing including a descendable nozzle, a spraying valve which opens in connection with a descending action of the nozzle, and pipe for leading a liquid in a container is attached to the top portion of the container.
  • a cylinder including a piston slidable inside the cylinder and an air pressurization valve which allows air pressurized by the slide of the piston to flow into the container is removably attached to the bottom portion of the container to extend inside the container.
  • the piston Since the cylinder, which is attached to the bottom portion of the container to extend therein, is naturally smaller than the container in diameter, resistance force applied to the piston inside the cylinder by the pressurized air in the container is not very great, and the piston can be reciprocated even after the air pressurization inside the container is advanced well enough. Accordingly, fully pressurized air can be accumulated in the container to ensure spraying of highly minute particles. If necessary, the piston may be made up of large and small pistons for higher pressure.
  • a means for releasing the airtightness between the seal of the piston and the inner wall of the cylinder is formed in the inner wall of the cylinder between the lock position of the piston and the forced-in position of the piston in sliding action.
  • the airtightness of the piston can be released by the airtightness release means when the piston is pressed toward the lock position beyond the forced-in position after the sliding action.
  • residual high-pressure air in a pressure chamber defined between a pair of one-way valves separately disposed at the distal ends of the cylinder and the piston escapes into the atmosphere, so that the piston can easily be moved to its lock position without receiving any resistance.
  • Such construction will ensure easy locking, as well as smooth sliding action, of the piston, unlike the prior art construction which requires blocking of an air intake during a pumping action.
