Here, order when assembling and disassembling relative to writing appliance main body 1 to the replacement box 2 and a tail 3 of present embodiment And the effect of each several part is described.

When box 2 and a tail 3 will to be replaced by screw thread feed motion be installed on writing appliance main body 1, first, replacing In the state of the part of the base end side of box 2 has inserted 3 inside of a tail, the driving for driving recess 32 and replacement box 2 of a tail 3 is made 212 concavo-convex engaging of projection.Then, in order that the negative thread 44 in the penholder portion 4 of the pin thread 31 and writing appliance main body 1 of a tail 3 Screw togather and apply to screw togather operating physical force by screw thread feed motion.At this moment, projection 212 is driven to be located at entering for the driving recess 32 In front of line direction, so these drive the touching of recess 32 to drive projection 212 and screw togather operating physical force from a tail 3 to the replacement transmission of box 2, The pin thread 213 for replacing box 2 is screwed togather with the negative thread 74 of the supply pipe 7 of writing appliance main body 1.So, a tail 3 is screwed together in Penholder portion 4, replaces box 2 and is screwed together in supply pipe 7.

But, in the installation of above-mentioned replacement box 2, with above-mentioned effect concurrently, replace box 2 and rotate relatively It is close in the rib 75 of uncapping of supply pipe 7, thus lid 22 is carried out from sealing posture (P) to the action for erecting posture (Q).Will at this moment The a series of action of uncap rib 75 and lid 22 be shown in Fig. 7 and describe in detail.

It is first begin to carry out the screw thread feed motion of a tail 3, quickly as Fig. 4 and Fig. 7 left ends are showed schematically, lid 22 It is close to, realizes the pressing starting position of the front end face 78 of shrouding 76 and the part contact near any edge part of lid 22.And And, former state propulsion screw thread feed motion when, as the figure left end rise the second component shown in, lid 22 start with imaginary axis be The spinning movement at center, the axis link relative 2 of phase place and the 90 ° of angles of partial transposition near any edge part Individual point.When screw thread feed motion is pushed further into, as the figure left end is risen shown in the 3rd component, the position of front end face 78 is to described Imaginary axis is moved closer to, thus the end 76a and the end 77a of location-plate 77 of the 76 of the touching of lid 22 Kaifeng plate While increase inclined degree, is pushed further into rotation.And, after from the pressing starting position, screw thread feeds 90 ° or so Action terminal, as shown in the figure right-hand member, the plate 76 that breaks a seal reaches 2 points on the imaginary axis or exceedes the imagination Axis, thus, be not only end 77a, location-plate 77 is connect with 22 face of lid in the state of lid 22 becomes and erects posture (Q) Touch.According to circumstances, the lid 22 is erected and be pressed against location-plate 77 under posture (Q) at this, is thus pressed in the case where posture (Q) is erected It is pressed on the inner face 21a of replacement box main body 21 and maintains the pressing.So lid 22 is realized erecting posture (Q), and thus lid 22 is not Barrier can be become, and stably pen core 6 can be reached from outer cylinder body 72 via supply pipe main body 71 as the ink of content.

In addition, in the present embodiment, in order to improve the performance for replacing 2 closed content of box, replace box main body 21 and There is any one party of lid 22 non-slip contact to be close to face X, in order to seal as content in the manufacturing process for replacing box 2 The ink of thing and the lid 22 is inserted insertion when, non-slip contact be close to face X not with respect to replace box main body 21 and The opposing party's sliding contact in lid 22 but be close to described the opposing party.Hereinafter, with reference to Fig. 8～Figure 12, while to pre- First it is arranged at and replaces the non-slip contact of box main body 21 and lid 22 and be close to face X and be described in detail.

As shown in FIG. 8 and 9, lid 22 is provided with the first ridge 221 and the second ridge 222, and in conduct The box main body 21 of replacing of container body is provided with the locking rib 214 of lid as sealing ridge, the first ridge 221 and the second ridge 111 are sealed with the state of the locking rib of clamp cover 214.Thus, between lid 22 and replacement box main body 21, from nib 5 Opposition side rise between interior lateral incline 215 and rear side inclined plane 224, between outer lateral incline 216 and front side inclined plane 225, And between the inner face 21a of top surface 226 and adjacent with outer lateral incline 216 replacement box main body 21 this 3 positions, throughout whole Continuously it is close on all ground.In other words, 3 resealings are carried out at 3 positions.Wherein, interior lateral incline 215, rear side is inclined Face 224 and front side inclined plane 225 become non-slip contact and are close to face X, in order to using the ink inclosure replacement box 2 as content Lid 22 is set in the operation for seal posture (P), the non-slip contact is close to face X and is not contacted with the opposing party's Slideslip, close It is close to the opposing party under envelope posture (P).

Next, while with reference to Figure 10～Figure 12, in order to the ink as content is enclosed replace box 2 and will lid The action of each several part that body 22 is set in the step of sealing posture (P) is illustrated.As shown in Figure 10, if making the first of lid 22 To the close direction movement for covering locking rib 214, then the projecting height of the second ridge 222 is bigger than the first ridge 221 for ridge 221 0.1mm, so mainly only top surface 226 and the inner face 21a sliding contacts for replacing box main body 21, in first ridge of time point 221 not with replace 21 side contacts of box main body.And, as shown in figure 11, when the first ridge 221 crosses the locking rib 214 of lid, Gai Ka Determine the 223 transient ground sliding contact of front side inclined plane of the outer lateral incline 216 and the first ridge 221 of rib 214.But, at this The front side inclined plane 225 of time point, the rear side inclined plane 224 of the first ridge 221 and the second ridge 222 also not with replace box master Any part contact of body 21.And, the moment on the summit for covering locking rib 214 is crossed in the first ridge 221, lid 22 becomes figure Sealing posture (P) shown in 12.At this moment, cover the rear side inclined plane of the interior lateral incline 215 and the first ridge 221 of locking rib 214 224 start to be close to mutually.Meanwhile, the front side inclined plane 225 of the second ridge 222 starts relative to the outer inclination for covering locking rib 214 It is close on inclined-plane 216.Thus, with cover the interior lateral incline 215 of locking rib 214, the rear side inclined plane 224 of the first ridge 221 and The front side inclined plane 225 of the second ridge 222 becomes the state that face X is close in non-slip contact, realizes sealing posture (P).

In addition, now top surface 226 is close to the inner face 21a for replacing box main body 21, but the second ridge 222 formed must be than first Ridge 221 is high, so the inner face 21a for covering the replacement box main body 21 of 5 side of nib of locking rib 214 is not contacted with lid 22. Thus, falling within non-slip and contacting with the position of the contact of top surface 226 on inner face 21a is close to face X.

By being set to structure as the above, according to present embodiment, posture (Q) is erected by lid 22 is positioned at, So that from sealing posture (P) lid 22 that relieves hinder will from replace the ink that box main body 21 be displaced outwardly movement this not Good situation disappears, and realizes the stable utilization of ink.

In order to more reliably be set to erect posture (Q) by lid 22, in the present embodiment, following structures are suitable for： The Kaifeng plate 76 is from contacting with lid 22 and the pressing starting position of face contact begins through screw thread feed motion and revolves It is changed into action terminal in the state of having turned more than 90 °.That is, the engaging for being pressed against the position of Kaifeng plate on lid 22 is released from When, lid 22 is entered from the axis of imaginaries at 2 positions of 90 ° of angles of position dislocation with phase place around the position for linking the pressing Row spinning movement.That is, if the plate that breaks a seal rotates against more than 90 ° and by gland body, the axis one is close to successively While being pressed till the axis.As a result, 22 action of lid can reliably be made until erecting posture (Q).

In the present embodiment, particularly, in order to will by Kaifeng pressing of the plate 76 to lid 22 be rapidly transitted into The posture changing of lid 22, and using it is described Kaifeng plate 76 and supply pipe 7 outer cylinder body 72 between be dimensioned so as to it is described as The thickness of the side wall of the replacement box main body 21 of container body is roughly equal.Thus, can suppress to replace box during screw thread feed motion The deformation of 21 side of main body, is thus pressed against the site boundary of Kaifeng plate 76 in lid 22, reliably releases 22 side of lid and lid The engaging of locking rib 214, the smooth spinning movement of the lid 22 after promotion.

And, in order to further improve the intensity of Kaifeng plate 76 and further smoothly carry out the posture changing of lid 22, at this In embodiment, the Kaifeng plate 76 is integrally constituted with the location-plate 77, by further improving the strong of Kaifeng plate 76 Spend and promptly the sealing posture (P) of lid 22 is released so as to press starting position, the smooth lid after thereby assisting in 22 action.

The smooth posture changing of the lid 22 when breaking a seal is guaranteed by realization structure as described above, meanwhile, it is another Aspect is set to following in the present embodiment in order to be reliably prevented spilling for the ink as content sealed under posture (P) Structure：There is any one party for replacing box main body 21 and lid 22 non-slip contact to be close to face X, in order to seal content Thing and during the insertion by any one party insertion for replacing box main body 21 and lid 22, face X phases are close in non-slip contact Face X is close in the non-slip contact for the opposing party's not sliding contact being close to described the opposing party.

That is, in the conventional replacement box as shown in structure as above-mentioned patent document 1, by being pressed against at that The fine scar that produces due to sliding over each other contact when lid is inserted container body and/or concavo-convex position is produced, so as to will Content is sealed.Therefore, content is spilt from the fine scar and/or concavo-convex position, or strong in order to avoid spilling Be about to lid diameter be set to it is larger.However, because having the fine scar and/or concavo-convex, though lid relative to Container is close to also produce capillarity etc. again by force, therefore can not avoid the leakage of content completely.And, if by force The diameter of increase lid and occurring more than need will lid pressing state to the container, then not only the fine scar and/or It is concavo-convex to be formed more notable, and stably lid can not be opened when using replacement box, when using the replacement box, lid Interfere the movement of content, this is also to become the reason for normally can not utilizing content.Therefore, in the present embodiment by head Face X is close in the above-mentioned non-slip contact of setting of first considering, and eliminates the unfavorable condition.
