DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figs. 1 to 3 show a rirst embodiment o~ the present invention.
In the drawings: the reference numeral 1 denotes a main body or an outer shaft Or a liquid appLicator in whlch is received an application-liquid, 2 a mouthpiece threadably connected to a front end Or the outer shart Or the liquid applicator; 3 an appl~cation-liquld conduit provided with a rlange li at its ~ront end, which flange 4 is integrally clamped between a front end of~the outer shaft 1 and the mouth-~ -5-:
Z4:2 1 piece 2; and 5 a sealing packing ring clamped between the rlange 4 and the mouthpiece 2.
A diameter Or an opening 7 Or the mouthpiece 2, which opening 7 is employed to hold the pen-core 6 therein, is smaller than an outer diame~er Or the pen-core 6. In an inner peripheral surface Or the opening 7 are circumferentially provided rour pieces Or rirst ridges 8 which are spaced apart from each other at equal circumf`erential intervals and contact.
their inscribed circle 9 at their radially innermost ends, which inscribed circle 9 is slightly smaller in diameter than the pen-core 6. The first ridges 8 axially extend over the substantially full length Or the pen-core holding opening 7 Or the mouthpiece 2.
Preferably, the first ridges 8 are elongated as long as possible.
In an inner peripheral surrace Or an appli-cation-liquid e~ecting opening 10 provided in a rront end portion Or an application-liquid conduit 3 communi-cated with the pen-core holding opening 7 of the mouth-piece 2, there are provided four pieces of second ridges 11 which are provided in positions corresponding to those Or the fLrst rldges 8 so as to be also spaced : apart rrom each other at equa;l circumrerential intervals whi~le axially extended. An inscribed circle 12 contacting 2 ~;~
1 the radially innermost ends Or the second ridges 11 is smaller in diameter than the inscribed circle 9 Or the first ridges 8, and, thererore, is considerably smaller in diameter than the pen-core 6.
The pen-core 6 is inserted into the pen-core holding opening 7 Or the mouthpiece 2 until the rear end Or the pen-core 6 abuts on the front ends Or the second ridges 11, 50 that the pen-core 6 is rixed and held by the first ridges 8 Or the mouthpiece 2. As a result, there is no rear that the pen-core 6 drops in the applicator even when the pen-core 6 is subjected to a pressure applied in the writing operation Or the applicator. In addition, slnce the first ridges 8 hold rirmly the pen-core 6 at top edge portions, the pen-core 6 can stay always in a very stable condition.
Further, as clearly shown in Fig. 2, the pen-core 6 is separated rrom the inner peripheral surface Or the pen-core holding opening 7 Or the mouthpiece 2 by means Or the rirst ridges 8 to form groove-like ~ rirst voids between the sames 8, which rirst voids .
are communicated wlth second voids defined in an appli-cation-liquid e~ecting hole 10 Or the~application-liquid conduit 3 at p~sitions between the second ridges 11 to make it possible t~at an appl:Lcation-liquid having 2S been received in the applicator is smoothly replaced : -7-, ~
`` ~29~2~
1 with an ex-ternal air to always facili~ate the reeding Or the application liquid Or the applicator in its writing operation, which second voids defined by the second ridges 11 are shown in Fig. 3.
As described above, the liquid appliator Or the present invention has a very simple construction which enales the pen-core 6 to be held always in a stable condition, and also enables the application liquid contained in the applicator to be smoothly replaced with the external air, and ~urther enables its assembling worlc to be easily conducted, and still rurther, ir necessary, enables the pen-core 6 to be easily replaced with a fresh one.
Figs. 4 to 7 show a second embodiment Or the present invention. In this second embodiment, another rirst ridges 8', which are similar to the rirst ridges 8 in construction, are provided in an inner peripheral surrace Or the application-liquid e~ecting hole 10 Or the application-liquid conduit 3, to make the pen-core 6 be held in a more stable condition. In this case, an inscribed clrcle Or the another first ridges 8' provided in the application-liquid ejecting opening 10 Or the application-liquid conduit 3 may have the same diameter as that Or the inscribed circle 9 Or the rirst ridges 8 provided in the pen-core holding -B-~29~2~Z
1 opening 7 of the mouthpiece 2, or may dirfer in diameter from the inscribed circle 9.
In this second embodiment, the another rirst ridges 8' provided in the application-liquid ejecting hole 10 Or the application-liquid conduit 3 are integrally rormed with the second ridges 11 in a continuous manner.
However, it is also possible to form them 8' and 11 separately so as to provide an axial gap therebetween.
Figs. 8 to 11 show a third embodiment Or the present invention. In this third embodiment, the pen-core 6 is covered with a sleeve member 13 made Or a material being non-permeable as to the applicatlon liquid. The sleeve member 13 is shorter in axial length than the pen-core 6 to make the pen-core 6 uncovered at its front and rear end portions.
The diameter of the inscribed circle 9 Or the rirst ridges 8 provided in the pen-core holding opening 7 Or the mouthpiece 2 is slightly smaller than an outer diameter of' the sleeve member 13, while the diameter o~ the inscribed circle Or the another rirst ridges 8' provided in the application-liquid e~ecting hole 10 Or the application-liquid aonduit 3 is slightly sma~ller than the outer diameter of the pen-core 6.
As a result, the inscribed circle 9 Or the f'irst ridges 8 is slightly larger in diameter than that Or the 9~Z~
1 another rirst ridges 8'.
In assembling, the rear end Or the pen-core 6 is abutted on the front ends Or ~he second ridges 11, while the rear end Or the sleeve member 13 is abutted on the front ends Or the another rirst ridges 8' provided in the application-liquid ejecting hole 10. Consequently, it is possible to hold the pen-core in a further more stable manner by the use Or the sleeve member 13 which may reinrorce the pen-core 6 and may eliminate a rear that the application liquid impregnated in the pen-core 6 aheres to the user's finger when the pen-core 6 is replaced with a fresh one.
Dirrerences in diameter between ~he inscribed circles and their corresponding outer diameters of 1$ the pen-core 6 and the sleeve member 13 are so deter-mined that the pen-core 6 or the sleeve member 13 is firmly held to a sufricient moderate degree. Excessive holding pressure i9 not prererable.
In these embodiments Or the present invention, each or~radially lnnermost end surfaces Or the first ~8 and the another first 8' ridges is shaped into an outwardly expanded arc~ e form a9 shown in Figs.
2, 5 and 9. On the other hand, each of radially innermost end surfaces Or the second ridges 11 is shaped ~into an inwardly retracted arc-like form as shown in , 34L2~;~
l Figs. 3, 6 and lO. However, it is also possible that each Or the radially innermost end surraces Or the ridges 8, 8' and ll is shaped into any other suitable form, for example, the radially innermost end surface of each Or the first 8 and the another first 8' ridges may be shaped into the same form as that Or the radially innermost end sur~ace Or each of the second ridges 11, or vice versa. In additlon, it is also possible to exchange the above-mentioned outwardly expanded arc-like form and the inwardly retracted arc-like rorm between the rirst ridges 8, 8' and the second ridges 11 .
Components o~ the liquld applicator of the present invention may be made Or conventionàl materials.
Since the present invention has the above con-struction, it is possible to prevent the pen-core 6 from dropping out Or the applicator through holding actions Or the first 8 and the another rirst 8' r-idges as to the pen-core 6. In addition, the pen-core 6 is stably held by these ridges 8, 8' while abutted on the rront ends Or the second ridges ll at its rear end to prevent itselr from dropping in the applicator when sub~ected to a pressure applied in the writing operation Or the appllcatorj so that the pen-core 6 is always held in a stable manner.
l Further, between the rirst ridges 8, the another rirst ridges 8' and the second ridges ll respectively, there are derined the groove-like voids which racilitate the replacement Or the application liquid with the external air to make the feeding of the application liquid smooth ln the writing operation of` the applicator.
As described above, the liquid applicator Or the present invention has a very simple construction with the use Or which are simultaneously accomplished a stable holding o~ the pen-core 6 and a smooth feeding Or the application liquid received in the applicator.
