Definitions

  • This invention relates to an container for an applicator for mascara, hairdye, eye shadow, eye liner, lip color, nail color, India ink, adhesive, etc., which accommodates an applying member having an applying portion inside a liquid reservoir chamber of a container main body in such a manner that the applying portion can retractably protrude outside the liquid reservoir chamber.
  • Applicator containers accommodating an applying member having an applying portion inside a liquid reservoir chamber of container main body in such a manner that the applying portion can retractably protrude outside the liquid reservoir chamber can be broadly classified into the following two kinds. One of them is an applicator container shown in Figs. 49 to 52, and the other is an applying container disclosed in Japanese Utility Model Laid-Open No. 63-11367/1988.
  • a shaft 101 of the container main body is shaped into a liquid reservoir chamber 102 for accommodating a liquid.
  • An opening member 104 having resilient function on the inner side is fixed to the inside of an open portion 103 of the shaft 101.
  • a screw 103a is threaded round the outer periphery of the open portion 103 and a cap 105 removably meshes with the screw 103a.
  • An elongated applying member 106 is fixed to the inside of the cap 105.
  • the applying member 106 fits to the opening member 104 and further fits freely to the liquid reservoir chamber 102. Needless to say, a liquid is charged into the liquid reservoir chamber 102, and the applying member 106, too, is immersed in the liquid.
  • Reference numeral 107 denotes an applying portion formed on or fixed to the front portion of the applying member 106, and brush-like member or a sponge-like member is integrally formed with, or fitted to, the applying portion.
  • a viscous liquid applicator container comprising a thinly elongated container portion for storing a viscous liquid, an open portion formed at the distal end of said container portion, and equipped with a wiping member, an applying member disposed inside said container portion, and capable of protruding through the open portion while wiping off the viscous liquid adhering in excess by the wiping member, a seal portion formed at the distal end of the applying member and sealing the container portion while in contact with the open portion, and a liquid holding member disposed at the distal end inside the container portion, holding the liquid adhering thereto, and capable of supplying the viscous liquid to the applying member even when the distal end of the container portion is directed upward.”
  • a feed member 27 feeds forth the viscous matter 12, the viscous matter 12 is then advanced to the liquid holding member 26, the viscous matter 12 so held by the liquid holding member 26 is then applied to the applying portion 16, and the applying portion 16 to which the viscous matter 12 is so applied is allowed to protrude from the open portion 13.
  • the liquid at the bottom 102a of the liquid reservoir chamber 102 cannot be supplied to the applying portion 107 in the course of use of the liquid, and the remaining liquid becomes wasteful.
  • the liquid adhering to the inner wall 102b of the liquid reservoir chamber 102 cannot be applied to the applying portion 107, either, and becomes extremely wasteful (see Fig. 52).
  • the gist of the present invention resides in that the liquid reservoir chamber is constituted by an easily deformable soft bladder.
  • the bladder gradually undergoes contraction as the liquid is used. Therefore, air or the like does not enter the bladder and the container keeps hygienic. Since the bladder gradually contracts as the liquid is used, the liquid can be consumed with minimum waste.

  • the hole 3 is bored in the opening member 4, the hole is not a complete hole in the meaning of the term, but is defined by a criss-cross notch 3a as shown in Fig. 3. Accordingly, when this applying container is not used, the applying member 7 expands the notch 3a, thereby forming the "hole” (see Fig. 1). When the container is used, on the other hand, the notch 3a restores and is closed (see Fig. 3). To always secure the seal property, the opening member is made of a material having high flexibility such as a synthetic rubber or soft polyethylene.
  • the material of the bag body 5 as the liquid reservoir chamber is a soft material such as polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, nylon, and so forth.
  • the material does not generate permeation and drying of the liquid.

  • Fig. 2 shows the state where engagement between the cap 6 and the open portion 2 of the shaft 1 is released and the coating member 7 is taken out from the bladder 5. At this time, the bladder 5 is contracted by the same volume as did the applying member 7. Accordingly, any space is not defined in the bladder 5 and air does not mix into the liquid. The bladder 5 undergoes contraction similarly when the quantity of the liquid drops in the course of use.

  • the inner hole portion of the shaft cylinder accommodating the applying member 12 can be utilized, as it is, as the liquid reservoir portion by paying attention to only liquid tightness at the boundary portion of each member, and can be easily utilized. According to this arrangement, however, the waste of the residual liquid becomes great, too, as already described. Therefore, the container shown in the drawings uses the soft bladder 14 made of polyethylene, polypropylene, polyvinyl chloride, nylon, etc. Preferably, this bladder does not cause permeation and drying of the liquid, and a three-layered structure formed by sequentially laminating polypropylene, polyvinyl chloride and low density polyethylene, for example, can be used.

  • a disc-like or spiral moving member 30 is integrally formed at the intermediate part of the applying member 18, but it is preferably shaped as a separate member. Easiness of assembly is one of the reasons, and another reason is that whereas the applying member 18 is desired to be molded from a relatively rigid material, the moving member 30 is desired to be made of a soft material.

As shown in Figs. 40, 41 and 42, sliding becomes smooth when a plurality of circumferential ribs 31b and longitudinal ribs 31c are formed at the fitting portion of the moving member 31b to the applying member 18. Even when sliding is thus made smooth, the press force for advancing the liquid is of course necessary.
  • a preferred example of the removable fixing method forms circular projections 16a, 32a round the inner wall of the shaft cylinder 16 and the outer periphery of the tail plug 32 as shown in Figs. 45 and 46 and meshes them, respectively, but the method is not particularly limited to this method but various other fixing methods can be employed.
  • the applying container may be the one in which a large diameter portion 18b having a somewhat greater diameter than that of the applying member 18 is formed at the applying member 18 or at the distal end of the applying portion as illustrated by the prior art technique or in Fig. 47.
  • a similar effect can be obtained by using the bladder according to the present invention.
  • the present invention can be applied to the applying container wherein the operation knob 16 is a mere tail plug portion (the bottom portion of the shaft cylinder 1), the applying member 18 is biased forward by a resilient member such as a coil spring and the applying member 4 protrudes upon removal of the cap B, and to the container wherein a slide piece 33 is fitted to the rear end of the applying member 18 and is moved in the longitudinal direction of the shaft cylinder 15 in place of the rotary mechanism, as shown in Fig. 48, and when the slide piece 33 is moved in the longitudinal direction of the shaft cylinder 15, the applying portion 18a is allowed to protrude from the opening member 19.
  • Reference numeral 15b represents a sliding groove in which the connecting portion between the slide piece 33 and the applying member 18 slides.
  • an applying member having an applying portion is stored in a liquid reservoir chamber of a container main body in such a manner that the applying portion can protrude outside the liquid reservoir chamber.
  • the applying container according to the present invention employs the construction wherein the liquid reservoir chamber is constituted by the bladder in the form of a bag which can sequentially contract with the consumption of the liquid. Therefore, air, etc., does not enter the bladder and, accordingly, the applying container of the invention is hygienic and can consume the liquid substantially to the last.
