1289458 墨26排出。 當使用完筆狀物之後，外蓋1 2再次旋入外部柄1 〇， 已在前文詳細描述之耦接效應，母螺紋元件4 8沿著公螺 元件50往後行進再次進入溝槽52。結果，在彈簧36的 響之下，控制推桿34再次朝抵接件62行進，在此處其 被支撐狀態。因此彈簧36不再藉由塞部30作用於油墨 上。在此情況下，並無任何普遍存在儲存機構24上增加 壓力，其從保護油墨26的觀點和關於避免滲漏的保護方 具有優點。此外彈簧36亦被保護。 當外蓋12被旋入外部柄10，塞部30從球珠20移開 直到母螺紋元件48通過進入溝槽52。使得在此情況下， 部30並不吸引油墨離開尖端18，塞部30係設置有螺旋 口 40，其結果爲拖曳塞部的形式。更具體地，在此情況 其可增加長度。 不使用螺紋20，亦可提供一插旋接頭用以將外蓋1 2 持在外部柄1 0上之。此例中，在某些情況下，可對藉由 接件先行限制增加的壓力，因爲當包含插旋接頭時，兩 件將被一起連接通過的角度在任何情況限制下可相對彼 旋轉。 爲了壓力限制之目的，可進一步提供當外蓋12旋入 部柄1 0時，排齒1 9僅在外蓋1 2軸向行程的一部份與環 2 1嚙合。 在圖面顯示的旋轉傳動裝置可補償儲存機構24中塡 程度的下降。更具體地，隨著塡充程度的減少，塞部30 漸移至儲存機構24，然而控制推桿34不會根據塡充程度 因 紋 影 爲 26 的 面 塞 切 下 固 抵 零 此 外 齒 充 逐 相 -11- -1289458 對於彈簧36改變其位置，且因此永遠可獲得相同的回復力 以產生增加的壓力。 尖端1 8相對於外部柄在軸向上的彈回描述於下。 第7圖顯示一操作狀態，其中外蓋1 2係未旋入，因此 筆狀物處在隨時可書寫狀態。特別是控制推桿34係親接至 塞部30,彈簧36受壓，且在儲存機構24獲得對應的壓力。 然而，仍然沒有軸向力作用在尖端18。 第8圖顯示一操作狀態，其不同於於第7圖，其中一微 ^ 小軸向力作用在尖端1 8。結果尖端1 8在軸向相對於外部柄 10被位移。當尖端18係在軸向耦接至殼部22，殻部22係 亦在軸向被相對於外部柄10位移。因殻部22藉由螺紋元 件48，50耦接至控制推桿34，控制推桿34亦被位移，更 具體地抵抗彈簧36的彈性回復力。因此彈性回復力係有效 抵抗尖端1 8相對於外部柄1 0的軸向位移。尖端1 8因此被 彈回。 第9圖顯示操作狀態，其中尖端1 8係在軸向被相對於 外部柄1 0以最大極限位移。當殼部22抵在抵接件66時， ^ 到達此狀態。抵接件66係設置在一抵接環68上，抵接環 68係軸向不可動地固持在外部軸10。與抵接件66呈對向 關係的抵接環68之側邊，可作爲控制推桿34之一抵接件， 以取代突部62。 在如圖示於圖式中之本發明更佳實施例，聚合物彈簧3 6 同時提供兩種目的，其一在儲存機構24製造增加的壓力， 其二在軸向彈回尖端1 8關於相對於外部柄1 0的位移。 揭示於前述說明、圖式以及申請專利範圍之發明特徵個 -12- 1289458 別上可爲必要的，且能以任何組合用於以各種不同實施例 實施本發明。 【圖式簡單說明】 本發明藉由參照附圖以較佳實施例更細節的敘述，其 中： 第1圖爲根據本發明較佳實施例之筆狀物之縱向剖面 圖； 第2圖顯示第1圖之筆狀物之塞部的部分剖面圖； | 第3圖顯示第1圖之筆狀物之控制推桿的部分剖面圖； 第4圖顯示第1圖之筆狀物之引導的或料匣的殼部； 第5圖與第6圖圖解地顯示第1圖之筆狀物之前部，和 筆狀物之外蓋之剖面圖；及 第7圖至第9圖分別表示第1圖筆狀物在不同操作狀態 之前部與後部。 【主要元件符號說明】 10 外部柄 12 外蓋 14 螺紋 16 密封部 18 尖端 19 排齒 20 球珠 21 環齒 22 殼部 24 儲存機構 -13- 1289458 26 油 Espi 28 密 閉 ±ct| 塊 30 塞 部 34 控 制 推 桿 36 彈 黃 38 關 閉 蓋 40 螺 旋 切 P 44, 46 突 部 48 母 螺 紋 元 件 50 公 螺 紋 元 件 52 溝 槽 54, 56，58，60 突 部 62 抵 接 件 64 抵 接 件 66 抵 接 件 68 抵 接 環 -14-1289458 IX. Description of the Invention: [Technical Field] The present invention relates to an applicator device comprising an outer casing and a coating mechanism. [Prior Art] Such various applicator devices are well known. They contain shapes such as a ballpoint pen. If such an applicator device is used in a substrate that is easily movable on the coating plane, conventional applicator devices are not suitable for coating thereon because of wrinkling, i.e., raised portions, which protrude from the plane of the substrate. . Uniform coating on such a substrate, e.g., coating a line of a certain line width, is as difficult as it is in the case of a substrate that is constructed to be visually perceptible. SUMMARY OF THE INVENTION It is an object of the present invention to improve such an applicator device as set forth in the opening paragraph of the specification, which is suitable for coating a substrate and a structural substrate which are movable. In accordance with the present invention, in such an applicator assembly as set forth at the outset of the specification, the object is achieved by the coating mechanism being movable relative to the outer casing to resist recombination. This is particularly an applicator device for a cosmetic product. When the applicator device of the present invention is applied to an easily movable substrate such as a skin or a surface such as a textile, the coating mechanism can resiliently spring back in the axial direction without the need to co-consider the user who is guiding the applicator device. Particularly when used on the skin, the advantage is that the male or female user only has to focus on the proper placement of the skin. In addition, the risk of injury is minimized when used near the eye area. If an attempt is made to produce a 1289458 line width line on a structural substrate, such as a textile or crepe paper, the applicator assembly in accordance with the present invention can be guided at a fixed interval that is less than the stroke of the set spring. By virtue of the elastic nature, the applicator device provides self-adjusting compensation relative to the coating plane housing spacing, as well as ensuring a line width. In addition, because the force in the coating direction is minimized by the application of the coating mechanism, the configuration of the spring force can reduce or completely eliminate the risk of folding or creping. In the case of coating the product on the skin, an effective self-adjusting mechanism provides the advantage that the pressure on the skin of the applicator device is substantially constant at any time within any range of spring effect adjustment, and It is independent of the spacing of the outer shell relative to the skin surface. The user can freely maintain the distance between the outer casing and the skin, and ensure that the required line width is evenly achieved. The self-adjusting mechanism can be adjusted over a relatively wide range by suitable adjustment of the maximum free stroke length and effective spring constant. This method makes it easy to provide a substrate that can accommodate structural features and/or can be easily moved, with regard to the length of the spring travel. Preferably, the coating device is movable relative to the outer casing between 0.05 mm and 10 mm, preferably 0.05 mm to 2 mm, more preferably 0.2 mm to 0.5 mm. 0. A preferred feature of the invention is that the restoring force is between Between 0.03 N and 50 N, preferably between 0·03 N and 10 N, more preferably between 0.03 N and 0.5 N. According to a further feature of the present invention, it is provided that the coating structure has a ball, and the quotient of the restoring force and the cross-sectional area of the ball is between 4 Pa and 6 GPa, preferably between 40 Pa and 1 GPa, more preferably It is between 1 kPa and 7 MPa. In accordance with an embodiment of the invention, particularly a simple preferred embodiment, one elastic element is provided to 1289458 to create a restoring force. A more preferred feature is that the resilient element is a spring. An embodiment is particularly simple, however, a more preferred embodiment of the invention is a coil spring element. According to a preferred embodiment of the invention, the elastic element comprises a polymeric material. It provides elastic elements that are particularly simple and inexpensive to manufacture. In addition, this material is very light. According to a further embodiment of the invention, the applicator device has a storage mechanism for the product to be coated, wherein the elastic element is further provided as an increased pressure generating device, Φ and adapted to be pressed against the boundary mechanism of the storage mechanism with its elastic restoring force for storage An increased pressure is created in the organization. In other words, an elastic means for both purposes is provided, i.e., the elastic bias of the coating mechanism resists axial displacement relative to the outer casing, and the other increases the pressure at the storage mechanism. This reduces the total number of individual parts and simplifies the coating mechanism as a whole. In accordance with a preferred feature of the invention, an increased pressure generating device is provided that is controllable in terms of pressure drop in the storage mechanism. This pressure drop involves reducing the load on the elastic means and thus provides the possibility of using polymeric materials for the elastic means, the advantages of which have been previously mentioned. In accordance with a preferred embodiment of the present invention, an increased pressure generating device is provided having a transmission having at least one female threaded member and at least one male threaded member, wherein the transmission can assume at least two operational states, i.e., a first operational state, wherein The two threaded members are intermeshing to create an increased pressure, and the first operational state 'where the two threaded members are not intermeshing to create an increase of 1289,458 plus pressure, thereby causing it to increase the pressure reduction. In other words, in accordance with this preferred embodiment of the present invention, the two threaded members are coupled together to create increased pressure and are separated to reduce the pressure at the storage mechanism. Therefore, it provides a solution from a simple form such as structure, low cost, and ease of operation. The user of the applicator device will forget to reduce the pressure on the storage device after the work is completed. In this case, the coated product may be damaged by the storage mechanism in some cases. In addition, it is not certain that the product will not leak out. According to a further preferred embodiment of the present invention, the applicator device is provided for exhibiting at least two operational states, i.e., a stopped state and a use state, and having means for reducing the pressure of the storage mechanism, the pressure reducing device being responsive to the applicator device Use state to stop state changes. In other words, the structure of the invention becomes a stop state as long as the applicator device is completed, and the pressure of the storage mechanism can be automatically lowered. In this regard, it is possible to provide an applicator device that changes from a use state to a stopped state by screwing in an outer cover. In addition to screwing into an outer cover, the outer cover can also be nested and secured by means of a bayonet connection. Therefore, its specific presentation is essentially an "automatic" organization. [Embodiment] Referring to Fig. 1, the pen has an outer shank 10 as a casing and an outer cover 12 which can be screwed. A thread is provided for this purpose, which is indicated by the symbol 14. The outer cover 12 has a sealing portion 16 which tightly surrounds the tip end 18 of the pen in the screwed-in state. A ball 20 is clamped to the free end of the tip 18. A row of teeth 19 on the outer cover 12 and a ring tooth 2 1 on the pen serve to rotationally couple the outer cover 12 to the tip when the screw is screwed into the tip 18 ° 1289458 away from the ball 20 At the end, the tip 18 is mounted to the guided or magazine housing portion 22. In this portion the tip end 18 has an annular inner contour and the shell portion 22 also has an annular outer contour, thus providing a slipping clutch 0. The inner space of the shell portion 22 forms a storage mechanism 24 for the ink 26. A closure mass is disposed in the storage mechanism 24 on the side away from the ball 20, which acts to block ambient air. The rear boundary of the storage mechanism 24 is formed by a plug portion 30. A control pusher 34 projects into the plug portion 30. φ A spring 36 pushes against the control push rod 34 and pushes against a closing cover 38. Spring 36 is a polymer spring. It can also be metal or other suitable material. As can be seen in Fig. 2, the spiral slit 40 is disposed on the plug portion 30, whereby the plug portion is variable with respect to its length. The result is a dragged plug. At its end remote from the tip end 18, the plug portion 30 has projections 44 and 46 which engage the corresponding recesses in the housing portion 22 for the purpose of rotational coupling. The plug 30 is thus rotatably coupled to the shell portion 22, but it is axially slidably retained therein. At its end remote from the tip end 18, the plug portion 30 is internally provided with two substantially hemispherical female threaded elements, one of which is designated by the reference numeral 48 and which is used to occasionally couple to the control push rod 34. The control pusher 34 is provided with a male threaded element that is complementary to the female threaded element 48 and one of which is designated, for example, by the symbol 50. The male threaded elements 50 correspond to the helical groove portions and each extend an angle slightly exceeding 300°. The spiral element 50 is interrupted by a longitudinal groove 52 extending at an angle of about 27°. At its end remote from the tip end 18, the control push rods 34 are provided with projections 5 4, 5 6, 58 and 60, for the purpose of rotational coupling, projections 54, 56, 58 and 60 -9 - 1289458 Engages with a corresponding recess in the outer shank 10. The control pusher 34 is axially slidable relative to the outer shank 1 between the closure cap 38 and the abutment 62 (see Figures 8 and 9). The function of the pen function is illustrated as follows: When the outer cover 12 is screwed into the outer handle 1 , the female thread member 48 is engaged in the groove 52. Therefore, in this operational state, there is no coupling between the control push rod 34 and the plug portion 3A. Therefore, the plug 30 does not apply any pressure to the airtight block 28 or the ink 26. It is important to have inks and/or close φ blocks that are not affected by permanent pressure. When the outer cover 12 is screwed into the outer shank 1 弹簧, the spring 36 releases the pressure. A polymeric spring can therefore be used. More specifically, when a polymeric spring is used, permanent stress can cause material fatigue. When the outer cover 12 is rotated relative to the outer shank for screwing out, the tip 18 is also rotated by the rotational coupling between the tooth 196 and the ring gear 2 1 . The plug 30 thus also rotates. In a further process of the rotational motion, the female thread member 48 exits the groove 52 and enters the male threaded member 50. The further rotational movement in this case provides that the female threaded member 48 is advanced along the male threaded member 50 so that the control pusher 34, which has been supported so far to resist the projection 62, is displaced against the spring 36. Currently only the spring 36 is under pressure. As a result, the elastic restoring force of the spring 36 is actuated by the control push rod 34 on the plug portion 30, whereby the pressure in the storage mechanism 24 is increased. At its end, the male threaded member 50 is restrained by the abutment member 64, and the female threaded member 48 abuts against the abutment member 64 in a further rotational movement. Although the rotational motion is continued, the sliding clip formed between the shell portion 22 and the tip end 18 causes the pressure in the storage mechanism 24 to not increase further. This is therefore advantageous for pressure sensitive inks. The increased pressure enhanced in the storage mechanism 24 can be used to vent the oil -10 - 1289458 ink 26. When the pen is used, the outer cover 12 is screwed into the outer shank 1 〇 again, and the coupling effect has been described in detail above, and the female thread member 48 travels back along the male screw member 50 to enter the groove 52 again. As a result, under the sound of the spring 36, the control pusher 34 again travels toward the abutment 62 where it is supported. Therefore, the spring 36 is no longer acted upon by the plug 30 on the ink. In this case, there is no ubiquitous increase in pressure on the storage mechanism 24, which has advantages from the viewpoint of protecting the ink 26 and the protection against leakage. In addition, the spring 36 is also protected. When the outer cover 12 is screwed into the outer shank 10, the plug portion 30 is removed from the ball 20 until the female threaded member 48 passes into the groove 52. In this case, the portion 30 does not attract the ink away from the tip 18, and the plug portion 30 is provided with a spiral opening 40, which results in the form of a drag plug. More specifically, in this case it can increase in length. Instead of using the thread 20, a plug connector can also be provided for holding the outer cover 12 on the outer handle 10. In this case, in some cases, the increased pressure can be limited by the adapter first, because when the plug connector is included, the angle at which the two pieces will be joined together can be rotated relative to each other under any circumstances. For the purpose of pressure limitation, it may be further provided that when the outer cover 12 is screwed into the handle 10, the teeth 19 are engaged with the ring 2 1 only in a portion of the axial travel of the outer cover 12. The rotary transmission shown on the drawing compensates for the reduction in the degree of enthalpy in the storage mechanism 24. More specifically, as the degree of replenishment is reduced, the plug portion 30 is gradually moved to the storage mechanism 24, however, the control push rod 34 is not cut and fixed according to the degree of replenishment due to the embossing of the facet of 26, and the teeth are charged. Phase-11--1289458 changes its position for spring 36, and thus the same restoring force is always available to produce increased pressure. The springback of the tip 18 relative to the outer shank is described below. Fig. 7 shows an operational state in which the outer cover 12 is not screwed in, so that the pen is ready to be written. In particular, the control pusher 34 is intimately coupled to the plug 30, the spring 36 is pressurized, and a corresponding pressure is obtained at the storage mechanism 24. However, there is still no axial force acting on the tip 18. Fig. 8 shows an operational state which is different from Fig. 7, in which a micro-miniature axial force acts on the tip 18. As a result, the tip end 18 is displaced in the axial direction relative to the outer shank 10. When the tip 18 is axially coupled to the shell portion 22, the shell portion 22 is also displaced axially relative to the outer shank 10. Since the shell portion 22 is coupled to the control push rod 34 by the threaded members 48, 50, the control push rod 34 is also displaced, more specifically against the elastic restoring force of the spring 36. Therefore, the elastic restoring force is effective against the axial displacement of the tip 18 relative to the outer shank 10. The tip 18 is thus bounced back. Fig. 9 shows an operational state in which the tip end 18 is axially displaced at the maximum limit with respect to the outer shank 10. When the shell portion 22 abuts against the abutment 66, ^ reaches this state. The abutment 66 is disposed on an abutment ring 68 that is axially immovably retained on the outer shaft 10. The side of the abutment ring 68 that is opposed to the abutment member 66 serves as an abutment member for the control pusher 34 to replace the projection 62. In a preferred embodiment of the invention as illustrated in the drawings, the polymer spring 36 provides both objectives, one of which creates an increased pressure in the storage mechanism 24 and the other in the axial direction of the tip 18 relative to The displacement of the outer handle 10 . The invention is disclosed in the foregoing description, the drawings and the scope of the claims. -12-1289458 may be necessary and may be used in any combination to practice the invention in various embodiments.
