Description

Cartridge mounting structure

The present invention relates to a cartridge mounting structure that is replaceable with respect to the main body.

Conventionally, by inserting a replaceable cartridge into the main body, the cartridge inside the container body is released from the sealed position in which the contents are sealed by the lid, and the cartridge can be used. Various structures have been proposed (see, for example, Patent Document 1).

However, depending on the operating position of the lid after inserting the cartridge, the lid itself may be an obstacle to the movement of the contents, and there may be a problem that the contents cannot be used suitably.

特許 Patent Document 1 applies the cartridge mounting structure to the structure related to the writing cartridge ink cartridge mounting. In the structure described in this document, writing can be performed without the ink being circulated to the outside because the lid body simply moves in parallel due to the pressing operation by the opening body that contacts the lid body at the time of insertion provided on the main body side. There is a concern about the inconvenience that it will disappear.

And the nib 5 and the supply pipe | tube 7 are each inserted in the inside of this batting 6 from the longitudinal direction both ends of this batting 6.

As shown in FIGS. 3 to 6, the supply pipe 7 is provided with a single supply pipe main body 71 whose pen tip 5 side is inserted into the batting 6 and an outer side of the supply pipe main body 71. An outer cylinder 72 for connecting the main body 71 and the ink cartridge 2 is provided. The supply pipe main body 71 has a protruding portion 71a for introducing ink into the inside of the filling 6 by being inserted into the filling 6 on the end surface of the pen nib 5 and one piece for circulating ink and air inside the inside.

Further, the supply pipe main body 71 has an elliptical cross-sectional shape. On the other hand, on the pen tip 5 side of the outer cylindrical body 72, there is provided an anti-rotation recess 72a for engaging with the long batting retaining rib 43 of the body portion 4 to prevent the supply pipe 7 from rotating. Yes.

In particular, as shown in FIG. 6, an inner wall 73 is provided on the inner side of the end of the outer cylinder 72 opposite to the pen tip 5, and the ink is interposed between the inner wall 73 and the outer cylinder 72. The leading end of the cartridge 2 is inserted. Further, on the inner surface of the end portion of the supply pipe 7 opposite to the nib 5, a female screw 74 for screwing the male screw 213 of the ink cartridge 2 and attaching the ink cartridge 2 to the supply pipe 7 is provided. In addition, a lid opening rib 75 is provided integrally with the inner wall 73 so as to hit the lid body 22 and press the lid body 22 to open. That is, a dimension between a lid opening rib 75 having an opening plate 76, which will be described later, and an outer cylinder 72, which is a side wall on the side of the writing instrument body 1, is set to be approximately equal to the thickness dimension of the side wall of the ink cartridge 2. . The end opposite to the nib 5 has a smaller diameter than the adjacent part, and the end of the supply pipe 7 is engaged with the protrusion provided on the body 4. I try to prevent it from coming off.

In this embodiment, as shown in FIG. 6, the lid opening rib 75 on the writing instrument body 1 side relatively presses the vicinity of the edge of the lid 22 by the screw feeding operation of the ink cartridge 2 and the cover 3. An opening plate 76 for operating the lid body 22 from the sealing posture (P), and an upright posture (1) provided integrally with the opening plate 76 and orthogonal to the sealing state (P) at the end of the screw feeding operation. And a positioning plate 77 which is a positioning body to be positioned in Q). As shown in FIG. 6, the unsealing plate 76 has a front end surface 78 formed so as to protrude from the surroundings so as to contact the lid body 22.

Here, the procedure when the ink cartridge 2 and the cover 3 of this embodiment are attached to and detached from the writing instrument body 1 and the operation of each part will be described.

When attaching the ink cartridge 2 and the cover 3 to the writing instrument main body 1 by screw feeding operation, first, with the base 3 side portion of the ink cartridge 2 inserted into the cover 3, The drive protrusion 212 of the ink cartridge 2 is engaged with the concave and convex portions. Then, a screwing operation force is applied by a screw feeding operation so that the male screw 31 of the cover 3 and the female screw 44 of the body 4 of the writing instrument body 1 are screwed together. At this time, since the driving projection 212 is positioned in front of the driving recess 32 in the advancing direction, the driving recess 32 and the driving projection 212 abut against each other, and the screwing operation force is transmitted from the cover 3 to the ink cartridge 2. The male screw 213 of the cartridge 2 and the female screw 74 of the supply pipe 7 of the writing instrument body 1 are screwed together. In this way, the cover 3 is screwed to the body 4 and the ink cartridge 2 is screwed to the supply pipe 7.

Accordingly, when the ink cartridge 2 is attached, the ink cartridge 2 rotates and approaches the lid opening rib 75 of the supply pipe 7 in parallel with the above-described action, so that the lid 22 is sealed. ) To the standing posture (Q). A series of operations of the lid opening rib 75 and the lid body 22 at this time will be described in detail with reference to FIG.

First, as shown schematically at the left end of FIGS. 4 and 7 for the first time as the screw feeding operation of the cover 3 is started, the lid body 22 comes close to the front end surface 78 of the opening plate 76 and a portion in the vicinity of an arbitrary edge of the lid body 22. Takes a pressing start posture in contact with. Then, when the screw feeding operation is advanced as it is, as shown second from the left end of the figure, the lid 22 is a virtual axis connecting two opposing points that are 90 ° different in phase from the portion in the vicinity of the arbitrary edge. Rotation around the center is started. When the screw feeding operation is further advanced, as shown in the third position from the left end of the figure, the position of the tip end surface 78 gradually approaches the virtual axis, whereby the lid 22 is positioned on the end 76a of the opening plate 76 and the positioning. The rotation is further advanced while increasing the inclination while hitting the end 77a of the plate 77. Then, as shown at the right end in the figure at the end of the operation, which is screwed about 90 ° from the pressing start posture, the unsealing plate 76 reaches the two virtual axis lines or exceeds the virtual axis line, thereby positioning plate 77. However, not only the end portion 77a but also the cover 22 is brought into surface contact with the standing posture (Q). In some cases, the lid 22 is maintained while being pressed against the inner surface 21a of the cartridge body 21 in the standing posture (Q) by being pressed against the positioning plate 77 in the standing posture (Q). Thus, when the lid 22 is in the standing posture (Q), the ink as the contents can be stably passed from the outer cylinder 72 through the supply pipe main body 71 without the lid 22 becoming an obstacle, and the batting. 6 can be reached.

In this embodiment, the cartridge body 21 is inserted when the lid 22 is inserted to seal the ink as the contents in the manufacturing process of the ink cartridge 2 so as to enhance the performance of the ink cartridge 2 for sealing the contents. The lid 22 has a non-sliding contact surface X that is in close contact with the other without sliding against the other and seals the ink. Hereinafter, the non-slidable contact surface X provided in advance on the cartridge body 21 and the lid body 22 will be described in detail with reference to FIGS.

As shown in FIGS. 8 and 9, a first protrusion 221 and a second protrusion 222 are provided on the lid body 22, and a lid locking rib 214 that is a sealing protrusion is provided on the cartridge body 21 that is a container body. The ridge 221 and the second ridge 111 are sealed in a state where the lid locking rib 214 is sandwiched. Thereby, between the lid body 22 and the cartridge main body 21, from the opposite side of the pen tip 5, between the inner inclined surface 215 and the rear inclined surface 224, between the outer inclined surface 216 and the front inclined surface 225, and The top surface 226 and the inner surface 21a of the cartridge body 21 adjacent to the outer inclined surface 216 are in close contact with each other over the entire circumference. In other words, the three places are triple sealed. Among them, the inner inclined surface 215, the rear inclined surface 224, and the front inclined surface 225 are in sliding contact with the other side in the process of setting the lid 22 in a sealing posture (P) so as to enclose the ink as the contents in the ink cartridge 2. In the sealing posture (P), the non-sliding contact surface X is in close contact with the other.

Next, with reference to FIGS. 10 to 12, the operation of each part in the process of setting the lid 22 in the sealing posture (P) so as to enclose the ink as the contents in the ink cartridge 2 will be described. As shown in FIG. 10, when the first protrusion 221 of the lid body 22 is moved in the direction of approaching the lid locking rib 214, the protrusion height of the second protrusion 222 is less than the first protrusion 221. Since it is 1 mm larger, only the top surface 226 mainly comes into sliding contact with the inner surface 21a of the cartridge body 21, and at this time, the first protrusion 221 does not touch the cartridge body 21 side. As shown in FIG. 11, when the first protrusion 221 gets over the lid locking rib 214, the outer inclined surface 216 of the lid locking rib 214 and the front inclined surface 223 of the first protrusion 221 gradually slide. Touch. However, even at this time, the rear inclined surface 224 of the first protrusion 221 and the front inclined surface 225 of the second protrusion 222 are not in contact with any part of the cartridge main body 21. Then, at the moment when the first protrusion 221 gets over the top of the lid locking rib 214, the sealing posture (P) shown in FIG. At this time, the inner inclined surface 215 of the lid locking rib 214 and the rear inclined surface 224 of the first protrusion 221 are in close contact with each other for the first time. At the same time, the front inclined surface 225 of the second protrusion 222 comes into close contact with the outer inclined surface 216 of the lid locking rib 214 for the first time. As a result, the inner inclined surface 215 of the lid locking rib 214, the rear inclined surface 224 of the first protrusion 221 and the front inclined surface 225 of the second protrusion 222 are in the non-sliding contact surface X. It becomes a sealing posture (P).

The top surface 226 is in close contact with the inner surface 21a of the cartridge main body 21 at this time, but the second protrusion 222 is formed higher than the first protrusion 221 and therefore is closer to the pen tip 5 than the lid locking rib 214. The inner surface 21 a of the cartridge body 21 does not touch the lid body 22 at all. Accordingly, the portion of the inner surface 21 a that contacts the top surface 226 also corresponds to the non-sliding contact surface X.

With this configuration, according to the present embodiment, the lid body 22 released from the sealing posture (P) by positioning the lid body 22 in the standing posture (Q) is moved out of the cartridge body 21. The problem of hindering the movement of the ink to be moved is solved, and the stable use of the ink is realized.

In the present embodiment, in order to make the lid body 22 more reliably in the standing posture (Q), the opening plate 76 is in contact with the lid body 22 by the screw feed operation and rotated by 90 ° or more from the pressing start posture. In this state, a configuration that is an operation termination is applied. That is, when the engagement of the location pressed on the opening plate in the lid 22 is released, the lid 22 rotates around a virtual axis that connects the pressed location and two locations that are 90 ° different in angle phase from the location. Perform the action. That is, if the unsealing plate presses the cover body while relatively rotating by 90 ° or more, the opening plate sequentially presses toward the axis to reach the axis. As a result, the lid 22 can be reliably moved to the standing posture (Q).

In particular, in this embodiment, in order that the pressing to the lid body 22 by the unsealing plate 76 can promptly lead to a change in the posture of the lid body 22, the space between the outer cylinder 72 of the supply pipe 7 with the unsealing plate 76. The dimension is set to be approximately equal to the thickness dimension of the side wall of the cartridge body 21 as the container body. As a result, the deformation of the cartridge body 21 side during the screw feeding operation is suppressed, so that the engagement between the lid body 22 side and the lid locking rib 214 around the location where the lid body 22 is pressed against the opening plate 76 is surely released. Then, the subsequent smooth rotation of the lid 22 is urged.

In this embodiment, the unsealing plate 76 and the positioning plate 77 are integrally formed so that the strength of the unsealing plate 76 is increased and the posture of the lid 22 can be changed more smoothly. By further increasing, the sealing posture (P) of the lid body 22 is quickly released from the pressing start posture, thereby contributing to the subsequent smooth operation of the lid body 22.

In order to ensure the smooth posture change of the lid 22 at the time of opening by realizing the configuration as described above, on the other hand, in order to surely prevent the leakage of ink as the contents in the sealed state (P). In the embodiment, any one of the cartridge main body 21 and the lid body 22 has a non-sliding contact surface X that is in close contact with the other without being in sliding contact with the other when inserted to seal the contents. It has a configuration.

That is, in the conventional cartridge as shown in the configuration of Patent Document 1 described above, when a lid is inserted into a container body, fine scratches, irregularities, and generated portions that are formed by sliding contact with each other are pressed as they are. I was trying to seal the contents. For this reason, in order to prevent the contents from leaking out from the position of the fine scratches or irregularities, or to prevent the leaking out, the diameter of the lid has been forcibly set large. However, as long as there are fine scratches and irregularities, leakage of contents cannot be completely avoided even if the lid is tightly attached to the container due to the occurrence of capillary action. Moreover, if the lid is forcibly increased in diameter and the lid is pressed against the container more than necessary, the fine scratches and irregularities are not only more prominently formed, but also the lid can be stabilized when the cartridge is used. This could cause the lid to interfere with the movement of the contents during use, and the contents could not be used normally. Therefore, in the present embodiment, the first problem of providing the non-sliding contact surface X has solved such a problem.

In addition, in the present embodiment, the lid body 22 has a plurality of first projections 221 and second projections 222 that are sealing ridges, and lid locking that is a lid stopping ridge provided at a predetermined position of the cartridge body 21. The rib 214 is sealed in a state of being sandwiched from inside and outside. Thereby, not only the radial direction of the cartridge main body 21 but also the working force for sealing is applied from the longitudinal direction, thereby contributing to more reliable sealing.

In order to realize more reliable sealing, in the present embodiment, the first inclined 221 has a rear inclined surface 224 formed on the rear side in the insertion direction and a front inclined surface 225 formed on the front side in the insertion direction of the second protrusion 222. Is defined as the non-sliding contact surface X that is in close contact with the lid locking rib 214 as the lid stopping ridge.

Further, in this embodiment, in order to realize reliable insertion at the time of insertion and reliable sealing in the sealing posture (P), the projecting dimension of the second projecting strip 222 is made larger than the projecting dimension of the first projecting strip 221. Largely set. Thus, the degree of sealing by forming the non-sliding contact surface X on the lid locking rib 214 and the first protrusion 221 while avoiding friction between the first protrusion 221 and the lid locking rib 214 during insertion. In addition to effectively increasing the pressing strength of the second protrusion 222 against the cartridge body 21 in the sealing posture (P), the degree of sealing by the second protrusion 222 and the lid locking rib 214 is also effectively increased. Yes.

The embodiments of the present invention have been described above, but the specific configuration of each part is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above embodiment, only the aspect in which the second protrusion on the lid is protruded larger than the first protrusion in the above embodiment has been disclosed, but of course, the aspect in which both protrusions have the same protrusion dimension, A mode in which the first protrusion is protruded larger may be applied. Further, in the above-described embodiment, the aspect in which the cartridge mounting structure is applied to the ink cartridge mounting structure in the writing instrument is disclosed, but of course, the present invention may be applied to various types in which the contents need to be sealed in the cartridge. .
