Definitions

  • the present invention relates to foam generating attachments attached for use to outer surfaces of discharge holes of common pump containers, aerosol containers and the like that contain various liquid contents
  • the present invention relates to a cylindrical member attached eternally, in a sense, and having a function of foaming the liquid contents flowing in from the discharge hole of the pump container or the like to which the cylindrical member is attached by making the liquid contents pass through a mesh and the like inside the cylinder and discharging the contents to outer space
  • the applicable liquid contents include, for example, soaps, sanitizers, cosmetics, milky lotions, shaving foams, hair styling mousses, detergents, hair dyes, shampoos, conditioners, insecticides and various others as will be described later
  • the word “container” is used herein to indicate not only a container body containing the liquid contents, but also a general arrangement from the container body to a nozzle. Also, the side of the discharge hole of the foam generating attachment (the left side in Fig 1 and other drawings) is referred to as “front”, and the side of the nozzle that is opposite thereto (the right side in Fig, 1 and other drawings) is referred to as “back”,
  • a discharging mechanism having a foam generating function of liquid contents contained in a pump container and the like is disclosed, for example, in the following Patent document 1.
  • a recess is provided at the tip (discharge hole) of a spraying nozzle for the container contents (nose drops), and a cylindrical nozzle tip for foam generation, together with a mesh member, is attached into the recess"
  • Patent document 1 Japanese Unexamined Patent Application Publication No 2008-132406
  • the recess is termed at the discharge hole at the tip of the nozzle itself, and the mesh member for foam generation and the cylindrical nozzle tip corresponding to its downstream member are incorporate in the recess, in a sense,
  • the cylindrical nozzle tip for foam generation is provided in an inner space area constituting a part of a nozzle tip portion as a discharging passage on the side of outputting the liquid contents
  • the present invention concerns the foam generating attachment for the container contents structured as above, and the pump product and the aerosol product including the foam generating attachment
  • the foam generating attachment formed by the cylindrical unit to be attached externally, in a sense, to the discharge hole for liquid contents is used as described above, which makes it possible to remove restrictions on the size of the foam generating member in manufacturing, and to further facilitate the attaching work itself of the foam generating member
  • a foam generating attachment of the present invention is applicable to both a pump container and an aerosol container, but a case of the pump container is illustrated in the drawings and explained in the following description only for the reason of simplifying explanation.
  • a component in the drawings has a reference numeral added with an alphabet (for example, an opening 1a), it basically means that the component is a part of a component having the same reference numeral (for example, a trigger lever 1).
  • reference numerals 6 to 6e are used only in Fig. 4 , a reference numeral 5' only in Fig. 7 , a reference numeral 5" only in Fig. 10 , and L1 to L5 only in Fig 1 , respectively
  • Fig 1 , Fig. 2 , Fig. 4 , Fig 7 and Fig. 10 illustrate:
  • the trigger lever 1, the piston 2, the nozzle 3, the nozzle tip 4, the foam generating attachments 5, 5', 5" and 6, the container body 7, the screw cap 8, the cover body 9, the member to prevent misoperation 10, the lattice mesh 11, the honeycomb mesh 12, the circular mesh 13 and the target mesh 14 are respectively made of plastic including polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate or the like
  • the components peculiar to the present invention are the attachments 5, 5', 5" and 6 only, and the contents discharging mechanism (pump container) itself, without the attachment, is for general purpose use.
  • a known pump mechanism (illustration omitted) that is provided inside the screw cap 8, the cover body 9 and the like operates to close its intake valve and open its discharge valve
  • the liquid contents contained in a storage space area between the intake valve and the discharge valve pass through "the passage for the contents 2a - the first space area 3a - the groove 4b - the second space area 4c - the hole 4a" to flow into the inner space area of the foam generating attachment 5 in mist.
  • the liquid contents flowed into the foam generating attachment 5 pass through the backside mesh 5e and also the front side mesh 5f to be discharged to outer space
  • Outside air is drawn in from the slits 5d and taken into the attachment corresponding to the amount of air used for generating the foamed contents, or corresponding to the flow of the liquid contents flowing into the foam generating attachment 5.
  • the lattice mesh 11, the honeycomb mesh 12, the circular mesh 13 and the target mesh 14 as shown in Figs 3 and the like are used as the backside mesh 5e and the front side mesh 5f incorporated in the foam generating attachment 5. This also applies to the respective meshes in the foam generating attachments 5', 5" and 6
  • the lattice mesh 11 is used in verification of contents discharging states as shown in Fig. 5, Fig. 6 , Fig. 8, Fig. 9 , Fig. 11 and Fig. 12
  • Fig 5 and Fig. 6 are photographed pictures of the contents discharging state when the foam generating attachment 5 that has both of the front side mesh 5f and the backside mesh 5e is attached to the pump product shown in Fig 1 (refer to Fig. 2 ).
  • Fig. 8 and Fig 9 are photographed pictures of the contents discharging state when the foam generating attachment 5' that has the backside mesh 5e only is attached to the pump product shown in Fig. 1 (refer to Fig. 7 )
  • Fig. 11 and Fig. 12 are photographed pictures of the contents discharging state when the foam generating attachment 5' that has the front side mesh 5f only is attached to the pump product shown in Fig. 1 (refer to Fig. 10 ).
  • the contents discharged from the foam generating attachment 5 are the most unified and creamy (refer to Fig. 5 and Fig. 6 ), followed by the contents discharged from the foam generating attachment 5" ( Fig. 11 and Fig. 12 ). However, the contents discharged from the foam generating attachment 5' are sufficiently unified (refer to Fig 8 and Fig. 9 ).
  • Fig 13 and Fig 14 are photographed pictures of the contents discharging state when an attachment that does not include a mesh is attached to the pump product shown in Fig. 1 ,
  • Basic characteristics of the foam generating attachment according to the present invention are that the cylindrical member attached to the outside of the discharge hole of the pump product and the aerosol product is provided, and the mesh and the like for foam generating operation is provided in the passage for the contents that is provided inside the cylindrical member
  • the foam generating attachment 6 shown in Fig. 4 consists of the two components only (the upstream molded member 6a and the downstream molded member 6d).
  • An inside diameter of the hole 6b for air intake formed in the upstream molded member 6a is 1 2 mm.
  • the values of the parts corresponding to the above-described lengths L2 to L4 are the same as those of the foam generating attachments 5, 5' and 5"
  • the piston 2 moves upward by the action of a coil spring (illustration omitted) of the known pump mechanism. Then, the trigger lever 1 rotates clockwise in the drawing by a camming action with the column 2b by the movement of the piston 2 to return to the rest mode as shown in Fig. 1 .
  • the present invention is not limited to the above-described embodiments, and, for example, projections and depressions, ribs and the like formed on the inner periphery of the foam generating attachment may be used as the component to allow the liquid contents to be stirred and foamed, other than the above-described mesh.
  • the number of the slits 5d for the air intake formed in the foam generating attachments 5, 5' and 5" and the number of the holes 6b for the air intake formed in the foam generating attachment 6 are arbitrary.
