Description

  The present invention relates to a fluid member pouring device and a fluid member pouring method.

  2. Description of the Related Art In various fields such as medical uses and physics and chemistry experiments, a fluid member dispenser such as a syringe has been used for the purpose of dispensing a desired amount of a fluid member to a predetermined position. The main part of the fluid member dispenser includes a cylindrical member that can be filled with the fluid member, a fluid member outlet provided at one end of the cylindrical member, and the other member of the cylindrical member. And an opening provided for inserting an extruding member for extruding the fluid member filled in the tubular member toward the fluid member outlet port into the tubular member.

  On the other hand, in recent years, for the purpose of restoration of teeth, a two-pack paste curing dental filling and restorative material (for example, see Patent Document 1) has been widely used. When such a dental filling / restoring material is used in the mouth, a fluid member dispenser in which two cylindrical members are arranged adjacent to each other is used (for example, see Patent Document 2). FIG. 6 is a schematic diagram showing an example of a conventional fluidity member dispenser used when using a two-pack paste dental filling / restoration material or the like. The flowable member dispenser 200 shown in FIG. 6 includes two cylindrical members 210 and 212 that are arranged in parallel and adjacent to each other, and a flowable member discharge port of these two cylindrical members 210 and 212 ( A mixer 220 attached to the tip of the (not shown) side, a flange 230 attached to the tip of the two cylindrical members 210 and 212 (not shown), and the inside of the cylindrical members 210 and 212 The pistons 240 and 242 are movable in the axial direction. Here, the mixer 220 is attached so as to cover each of the fluid member outlets of the cylindrical members 210 and 212. In addition, the cylindrical members 210 and 212 have a circular cross-sectional shape on both the outer peripheral side and the inner peripheral side. Furthermore, the cross-sectional shape of the cross section having the maximum area of the pistons 240 and 242 is substantially the same shape and size as the cross-sectional shape on the inner peripheral side of the cylindrical members 210 and 212. In addition, as the pistons 240 and 242, a piston made of a columnar rubber material (rubber piston) or a piston in which a ring-shaped rubber packing is attached to the outer peripheral surface of a columnar resin member (a piston with a rubber packing) is used. Is done.

  When using the fluidity member dispenser 200, first, the first fluidity member is filled in the space between the fluidity member outlet side in the cylindrical member 210 and the piston 240, and the second fluidity member dispenser 200 is used. The fluid member is filled in a space between the fluid member outlet side in the tubular member 212 and the piston 242. In this state, a columnar pushing member (not shown) is inserted from the opening side of the cylindrical members 210 and 212, and the pushing member is pushed from the opening side to the fluid member outlet side. As a result, the first fluid member and the second fluid member filled in the cylindrical members 210 and 212 are poured into the mixer 220 through the fluid member outlet, and into the mixer 220. The first fluid member and the second fluid member are mixed. Furthermore, the mixed fluid member in which the first fluid member and the second fluid member are mixed is discharged to the outside from the mixed fluid member outlet 222 provided at the tip of the mixer 220. . In performing such a pouring operation, a push-type extruder (see, for example, Patent Document 2) or an extruder that includes a manual lever and uses the principle of a saddle (see, for example, Patent Document 3) is used. .

  FIG. 7 is a schematic diagram illustrating an example of a push-type extruder. The extruder 300 shown in FIG. 7 includes two columnar extrusion members 310 and 312 arranged in parallel and adjacent to each other, a pressing plate 320 attached to one end of the extrusion members 310 and 312, and a through hole. The push-out members 310 and 312 have a flange holder 330 that is slidable in the axial direction in the through-hole. The flange holder 330 is provided with an insertion hole 332 corresponding to the flange 230. And when using the fluidity member extraction device 200, the flange 230 is inserted into the insertion hole 332, and the fluidity material extraction device 200 and the extruder 300 are fixed to each other. Thereby, the extrusion members 310 and 312 can be smoothly inserted into the cylindrical members 210 and 212. In addition, a guide member 334 that guides the sliding of the extrusion members 310 and 312 in the axial direction is attached to the pressing plate 320 side of the flange holder 330.

  FIG. 8 is a schematic diagram showing an example of a manual lever type extruder, in which FIG. 8A shows a side view and FIG. 8B shows a top view. The extruder 400 shown in FIG. 8 has a main part integrated with the main body 410 on the lower side of the main body 410, a main body 410, an extrusion member 420 disposed so as to penetrate the main body 410. And a manual lever 440 that is attached to the lower side of the main body 410 and disposed at a position facing the grip 430. The manual lever 440 can be pushed into the grip 430 side (the direction opposite to the arrow P direction in the figure). The manual lever 440 pushed into the grip 430 is automatically moved away from the grip 430 (arrow P direction side in the figure) by a spring member (not shown) provided in the main body 410. , It is supposed to return to its original position. In addition, when the manual lever 440 is pushed into the grip 430, the pushing member 420 can be pushed in the axial direction (in the direction of arrow P in the figure) by a predetermined amount in the main body 410. A utilized extrusion member extrusion mechanism (not shown) is incorporated.

  The extruding member 420 has two columnar extruding portions 422 and 424 that are branched in two on the way from the end opposite to the arrow P direction to the end of the arrow P direction, and are parallel to each other. ing. An insertion hole 412 corresponding to the flange 230 is provided in a region on the left side surface of the main body 410 on the arrow P direction side. And when using the fluidity | liquidity pouring device 200, the flange 230 is inserted in the insertion hole 412, and the fluidity | liquidity material pouring device 200 and the extruder 400 are mutually fixed. Thereby, the extrusion parts 422 and 424 can be smoothly inserted into the cylindrical members 210 and 212.

WO2006 / 030645 (Claim 1 etc.) WO2007 / 095769 (FIG. 1 etc.) WO2006 / 15506 (Fig. 1 etc.)

  Among the extruders 300 and 400 shown in FIGS. 7 and 8, the push-type extruder 300 has a stronger force than the force applied to the manual lever 440 compared to the manual lever-type extruder 400. It cannot be poured out unless it is added. For this reason, the push-type extruder 300 is inferior to the manual lever-type extruder 400 in terms of precise control of the dispensing amount. Therefore, when precise control of the amount to be dispensed is required; for example, when the fluid member to be dispensed is expensive and it is necessary to minimize the wasteful waste of the fluid member, or the place to dispense On the other hand, when there is a great need to pour a fluid member by a predetermined amount without excess or deficiency, a manual lever type extruder 400 is preferably used as the extruder.

  On the other hand, in the fluid member dispenser of the type illustrated in FIG. 6 in which the piston is disposed in the cylindrical member, when a rubber piston is used as the piston, the fluid member outlet side of the cylindrical member and the piston The fluid member filled between the two tends to leak to the opening side by pressurization at the time of dispensing. Therefore, in order to prevent leakage of such a fluid member, it is preferable to use a piston with rubber packing as the piston.

  However, when the fluid member extraction device 200 using a piston with rubber packing as the pistons 240 and 242 and the manual lever type extruder 400 are used in combination, the cylindrical members 210 and 212 may be broken. there were. Such cracks are caused by, for example, a fluid member having viscosity (particularly a resin syringe filled with a fluid member having viscosity such as used in dental filler applications). This is particularly likely to occur when the paste) is used or the cylindrical members 210 and 212 are made of a resin member having a thickness of about 0.7 mm to 1.3 mm. This is because the manual lever type extruder 400 using the principle of scissors has a flow filled in the cylindrical members 210 and 212 via the pistons 240 and 242 as compared with the manual push type extruder 300. It is estimated that the pressure applied to the sex member is higher. In order to solve such a problem, it is preferable to use a rubber piston. However, in this case, leakage of the fluid member occurs.

  This invention is made | formed in view of the situation mentioned above, and the fluid member with which the cylindrical member of the fluid member extraction device was filled compared with the case where it pours out using a push-type extruder. Even when the pressure applied to the fluid member is higher, the fluid member dispenser and the fluid member member are prevented from being damaged while at the same time suppressing the leakage of the fluid member in the fluid member dispenser. It is an object to provide an exit method.

  In order to solve the above-mentioned problems, a fluid member dispenser according to the present invention includes a cylindrical member that can be filled with a fluid member therein, and a fluid member spout provided at one end of the tubular member. And an opening provided at the other end of the cylindrical member, and is arranged in the cylindrical member so as to be movable along the axial direction, and reversibly deformable with respect to the axial direction. The first member and the cylindrical member are arranged to be movable along the axial direction of the first member, and are composed of a main portion having a rigidity higher than that of the first member. A second member that is in close contact with the inner peripheral surface of the cylindrical member so as to prevent the inside of the cylindrical member from moving along the axial direction. To the outlet, the first member and the second member are arranged inside the cylindrical member in this order. In which was formed.

  In the fluidity member dispenser adopting such a configuration, the second member has an inner peripheral surface of the tubular member so as to prevent the fluidity member from moving in the tubular member along the axial direction. It is in close contact with. For this reason, even if a fluid member is filled between the fluid member outlet port side and the second member in the cylindrical member, the fluid member does not leak to the opening side. In addition to this, since the second member is composed of a main part having higher rigidity than the first member, it does not substantially deform even when a strong pressure is applied. For this reason, even when the fluid member filled between the fluid member outlet side in the cylindrical member and the second member is in a high pressure state, the second member is not deformed. Adhesion between the member and the inner peripheral surface of the cylindrical member can be maintained. Therefore, even in such a case, the fluid member does not leak to the opening side.

  The first member and the second member are disposed in this order in the cylindrical member from the opening to the fluid member outlet. For this reason, when inserting and extruding an extrusion member from the opening side in a state where the fluidity member is filled between the fluidity member outlet side and the second member in the cylindrical member, the extrusion member The pressing force by is transmitted to the second member via the first member, and further filled into the cylindrical member between the fluid member outlet side and the second member from the second member. It is transmitted to the fluid member. The first member can be reversibly deformed with respect to the axial direction. For this reason, the pressing force by the pushing member is not directly transmitted from the first member to the second member and the fluid member, and a part of the pressing force is deformed so that the first member contracts in the axial direction. As a result, it is temporarily absorbed and accumulated as deformation energy. Therefore, the pressure applied to the fluid member filled in the cylindrical member can be kept low compared to the case where the pressing force by the pushing member is directly transmitted to the fluid member. Therefore, the breakage of the fluid member dispenser can be suppressed. Further, the deformation energy stored by the first member deforming in the axial direction is at a position where the pushing member inserted into the cylindrical member is fixed in a stationary state in contact with the first member. In this case, the force is gradually released as a force for pressing the second member. Therefore, in this case, the loss of the pressing energy used for dispensing does not occur.

  Moreover, as for the one aspect | mode of the fluid member extraction device of this invention, it is preferable that said 1st member is comprised from a rubber material.

  In the fluid member dispenser adopting such a configuration, the first member is elastically deformed in the axial direction, so that a part of the pressing force by the pushing member is absorbed and accumulated as deformation energy in the first member. Is done. For this reason, the pressing force transmitted to the second member or the fluid member can be further reduced, and as a result, damage to the fluid member dispenser can be suppressed.

  Further, according to another aspect of the fluid member dispenser of the present invention, the second member has a columnar rigid member having a cross-sectional shape substantially the same as the cross-sectional shape of the inner peripheral side of the cylindrical member, It is preferable to be composed of a ring-shaped rubber packing disposed on the outer peripheral surface of the rigid member.

  In the fluidity member dispenser adopting such a configuration, since the rubber packing that is an elastic body is disposed between the rigid member and the inner wall of the cylindrical member, the rubber packing and the rigid member And the rubber packing and the inner wall of the cylindrical member are in close contact with each other without a gap. For this reason, the phenomenon (leakage of the fluid member) in which the fluid member passes between the outer peripheral surface of the second member and the inner wall surface of the cylindrical member and leaks to the opening side can be suppressed. In addition to this, since the second member comes into strong contact with the inner wall surface of the cylindrical member via the flexible rubber packing, the second member smoothly moves in the axial direction in the cylindrical member. Easy to move to.

  In another aspect of the fluidity member dispenser of the present invention, the first member and the second member are arranged in this order from the opening to the fluidity member outlet. The two cylindrical members are arranged, and the first cylindrical member and the second cylindrical member are arranged adjacent to each other so that their axial directions are parallel to each other, and in the axial direction. On the other hand, it is preferable that the fluid member outlet and the opening of the first tubular member and the second tubular member are arranged on the same side.

  Since the fluidity member dispenser adopting such a configuration can dispense two kinds of fluidity members on the same side, it is extremely easy to mix these two kinds of fluidity members simultaneously with the dispensing. . For this reason, in the case of using a material that exhibits utility value by mixing two kinds of fluid members (for example, a curable material that cures by a chemical reaction when two kinds of fluid members are mixed), 2 It is possible to simplify the pouring and mixing operation of the kinds of fluid members.

  The first fluid member extraction method of the present invention includes a columnar extrusion member having a cross-sectional shape that can be inserted into the hollow part of the tubular member of the fluid member extractor of the present invention, and a manual lever. An extruding device having an extruding member extruding mechanism that converts the movement of the manual lever into an operation of extruding the extruding member in the axial direction using the principle of scissors, and fluidity in the cylindrical member The fluid member dispenser of the present invention in which a fluid member is filled between the member outlet side and the second member, the axial direction of the extrusion member, and the tubular member of the fluid member dispenser After the distal ends of the extruding members are fixed to each other in a state of being inserted from the opening of the fluidity member dispenser so that the axial directions of the extruding members coincide with each other, the manual lever is operated to By extruding from the opening side of the cylindrical member to the fluid member outlet side, the fluidity is The wood from fluidity member spout is intended that dispense to the outside of the flowable member pouring device.

  In this fluid member pouring method, the movement of the manual lever is converted into the movement of the pushing member by using the principle of scissors, so that the pouring can be carried out without strongly operating the extruder. In addition to this, since the above-described fluidic member dispenser of the present invention is used as the fluidic member dispenser, damage to the fluidic member dispenser and leakage of the fluidic member can be suppressed.

  Further, the second fluid member pouring method of the present invention is a columnar extruding member having a cross-sectional shape that can be inserted into a hollow part of a cylindrical member constituting the fluid member pouring device, and attached to the tip of the extruding member. A distal end member that is reversibly deformable with respect to the axial direction of the push-out member, and a manual lever, and the movement of the manual lever is controlled by using the principle of scissors. An extruding device having an extruding member extruding mechanism for converting into an extruding operation, a cylindrical member capable of being filled with a fluidic member, and a fluidic member provided at one end of the cylindrical member. An outlet, an opening provided at the other end of the cylindrical member, and a main member which is disposed in the cylindrical member so as to be movable along the axial direction and has higher rigidity than the tip member. And the fluid member is formed along the axial direction. A columnar member that is in close contact with the inner peripheral surface of the cylindrical member so as to prevent the inside from moving, and the fluidic member between the fluidic member outlet port and the columnar member in the cylindrical member The fluidic member dispenser filled with the fluidizing member is placed on the tip of the extruding member so that the axial direction of the extruding member coincides with the axial direction of the cylindrical member of the fluidizing member dispenser. After fixing each other in the state of being inserted from the opening of the flexible member dispenser, the manual lever is operated to push the pushing member from the opening side of the cylindrical member to the fluid member pouring port side. Thus, the fluid member is poured out from the fluid member outlet through the fluid member outlet.

  In this flowable member pouring method, the function of the first member used in the above-described flowable member pouring device of the present invention is imparted not to the flowable member pouring device side but to the extruder side. That is, in the second fluid member pouring method of the present invention, the columnar member constituting the fluid member pouring device corresponds to the second member of the fluid member pouring device of the present invention, The tip member attached to the tip of the extrusion member of the extruder corresponds to the first member of the fluid member dispenser of the present invention. For this reason, at the time of pouring, like the fluidity member dispenser of the present invention, from the opening portion to the fluidity member pouring port, the tip member having substantially the same function as the first member, and the second member A columnar member having substantially the same function as the member is arranged in this order in the cylindrical member. Therefore, the second fluid member dispensing method can be dispensed without strongly operating the extruder by hand, similarly to the first fluid member dispensing method. It is possible to suppress breakage of the dispenser and leakage of the fluid member.

  As described above, according to the present invention, the pressure applied to the fluid member filled in the tubular member of the fluid member dispenser, compared to the case of dispensing using a hand-held extruder. The flowable member pouring device and the flowable member pouring method for suppressing breakage of the flowable member pouring device and suppressing leakage of the flowable member in the flowable member pouring device even when the flow rate becomes higher Can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional view showing an example of a fluid member dispenser of the present invention. The main part of the fluid member dispenser 100 shown in FIG. 1 includes a cylindrical member 110, and a first member 120 and a second member 130 arranged in the cylindrical member 110.

-Cylindrical member-
The cylindrical member 110 is a cylindrical member having a constant inner diameter with respect to the axial direction indicated by the alternate long and short dash line in the figure. The cross-sectional shape on the inner wall surface side of the cylindrical member 110 is not particularly limited, but is usually preferably a circular shape. A fluid member outlet 112 is provided at one end of the cylindrical member 110, and an opening 114 is provided at the other end. The fluid member outlet 112 has an opening diameter that is smaller than the inner diameter of the cylindrical member 110. The shape of the fluid member outlet 112 is not particularly limited, and the opening may be provided only on the surface intersecting the axial direction of the cylindrical member 110 (that is, the length is 0), as illustrated in FIG. Moreover, you may have the convex shape which has predetermined | prescribed height with respect to the surface which cross | intersects the axial direction of the cylindrical member 110. FIG. Moreover, you may attach various adapters, such as an elongate cylindrical extraction guide (not shown), to the fluid member pouring port 112 as needed. The opening 114 has substantially the same shape and size as the cross-sectional shape on the inner wall surface side of the cylindrical member 110. In order to facilitate the insertion of the extrusion member into the cylindrical member 110, the opening 114 has a shape and size slightly different from the same shape and size as the cross-sectional shape on the inner wall surface side of the cylindrical member 110. You may make it large. In addition, in order to facilitate attachment and fixing to an existing extruder as illustrated in FIGS. 7 and 8, the other end of the cylindrical member 110 (the end on the side where the opening 114 is provided) A flange 116 may be provided as illustrated in FIG.

  The material constituting the cylindrical member 110 is not particularly limited, and any known material can be used as long as an appropriate strength can be secured in order to stably hold the fluid member such as resin, metal, glass, and ceramic. Is available. Among these materials, a resin is most preferable from the viewpoint of the cost when forming the cylindrical member 110, molding processability, and the like. For example, polypropylene, polyethylene, acrylic resin, nylon resin, ABS resin, fluorine-based resin, or A mixture of these resins, a mixture of these resins with a filler, or the like can be used. Further, the material constituting the cylindrical member 110 may be transparent or translucent, but when the fluid member filled in the cylindrical member 110 is denatured or deteriorated by visible light or ultraviolet light, It is preferably opaque.

  Moreover, the capacity | capacitance of the cylindrical member 110 is not specifically limited, It can select suitably by a use. However, for example, medical applications such as using a dental filling composite resin in the mouth, and other times, about 0.05 cc to 1 cc or less (more preferably 0.1 cc to 0.7 cc or less in a single dispensing operation) (A) the capacity is preferably in the range of 1 cc to 50 cc, preferably in the range of 2 cc to 20 cc. More preferably. The term “capacity” as used herein means the maximum capacity of the fluid member that can be filled in the cylindrical member 110 without the first member 120 and the second member 130 being disposed in the cylindrical member 110. To do. In this case, from the viewpoint of ensuring an appropriate dispensing speed, the opening diameter (equivalent circle equivalent diameter) of the (B) fluid member outlet 112 is preferably 0.5 mm or more and 10 mm or less, preferably 1 mm or more. More preferably, it is 5 mm or less. Furthermore, the thickness of the cylindrical member 110 (the value obtained by subtracting the inner diameter from the outer diameter is not particularly limited and can be appropriately selected depending on the application. However, in the application of handling a relatively small amount of the fluid member as described above, From the viewpoint of achieving both mechanical strength and moldability of the cylindrical member 110, (C) the thickness is preferably in the range of 0.5 mm to 2.0 mm, and 0.7 mm to 1.3 mm. In addition to these, in applications where a relatively small amount of flowable member as described above is used, (D) the inner diameter of the flowable member dispenser 100 is the existing extruder. 3 mm or more and 30 mm or less is preferable, and 5 mm or more and 15 mm or less is more preferable.

-First member-
(1) The first member 120 is disposed so as to be movable along the axial direction in the cylindrical member 110 when the pushing member is inserted from the opening 114. Thereby, the first member 120 can receive the pressing force by the pushing member and transmit it to the second member 130. (2) Further, as the first member 120, a member that can be reversibly deformed in the axial direction is used. Thereby, when a strong pressing force is applied to the first member 120, the first member 120 is deformed so as to contract in the axial direction. As a result of this deformation, the pressing force transmitted from the first member 120 to the second member 130 is more than the pressing force transmitted from the pressing member (not shown in FIG. 1) to the first member 120. Can be smaller. For this reason, destruction of the cylindrical member 110 due to transmission of a strong pressing force from the second member 130 to the fluid member can be suppressed.

  As the first member 120, any member having the above-described two functions can be used without any particular limitation. However, the first member 120 is preferably made of a rubber material as illustrated in FIG. 1 from the practical point of view such as availability of members and cost. The hardness of such a rubber material is not particularly limited, but from the viewpoint of suppressing the operability when the fluid member is poured out and the breakage of the fluid member dispenser which is the object of the present invention. The hardness according to K 6301 is preferably 30 or more and 100 or less, and particularly preferably 50 or more and 80 or less. Specific examples of rubber materials include natural rubber, isoprene rubber, butadiene rubber, chloroprene rubber, nitrile rubber, butyl rubber, ethylene-propylene rubber, ethylene-vinyl acetate rubber, acrylic rubber, chlorosulfonated polyethylene, chlorinated polyethylene, Examples include epichlorohydrin rubber, urethane rubber, silicone rubber, and phosphazene-based fluororubber. Among these rubber materials, isoprene rubber, butadiene rubber, nitrile rubber, urethane rubber, and silicone rubber are preferable from the viewpoint of operability when the fluid member is poured out.

  The shape of the first member 120 is not particularly limited. However, the cross-sectional shape of the first member 120 is substantially the same as the cross-sectional shape on the inner surface side of the cylindrical member 110 in order to receive the pressing force applied by the pushing member and reliably transmit it to the second member 130. It is preferable that the cross-sectional area of the first member 120 is the same as the cross-sectional area on the inner surface side of the cylindrical member 110. In particular, it is preferable that a part slightly larger than the cross-sectional area on the inner surface side of the cylindrical member 110 is disposed in the cylindrical member 110 with a little compression. In this case, since the outer peripheral surface of the first member 120 is more uniformly and strongly adhered to the inner surface of the cylindrical member 110, leakage of the fluid member can be more reliably prevented. Further, the axial length of the first member 120 can be appropriately selected according to the pressing force applied by the pushing member. That is, when the pressing force applied by the pushing member is relatively strong, the axial length is made longer, and when the pushing force applied by the pushing member is relatively weak, the axial length is made shorter. can do.

  In addition, when the cylindrical member 110 satisfy | fills the conditions shown to (A)-(D) mentioned above, as axial direction length of the 1st member 120 comprised from a rubber material, it shall be 3 mm or more and 30 mm or less. It is preferably 5 mm or more and 15 mm or less. When the axial length is less than 1 mm, when the pressing force applied by the pushing member is strong, the pressing force is transmitted to the second member 130 without being sufficiently absorbed by the first member 120. For this reason, the cylindrical member 120 may be damaged. When the axial length exceeds 30 mm, the pressing force applied by the pushing member may be absorbed by the first member 120 and may not be sufficiently transmitted to the second member 130. As a result, the dispensing speed may be significantly reduced or the dispensing itself may be difficult. As the first member 120 made of a rubber material, a rubber piston used in the already commercially available fluid member dispenser illustrated in FIG. 6 may be used.

  On the other hand, the first member 120 includes, for example, two plates opposed to the extruded member side and the second member 130 side, in addition to the members formed of the rubber material illustrated in FIG. A member composed of a spring disposed between the plates can be used. In this case, the spring constant of the spring to be used can be appropriately selected according to the pressing force applied by the pushing member.

-Second member-
(1) The second member 130 can move along the axial direction in the cylindrical member 110 by transmitting the pressing force from the first member 120 pushed by the pushing member. Thereby, the fluidity which received the pressing force applied by the 1st member 120, and was filled in the cylindrical member 110 between the 2nd member 130 and the fluid member pouring port 112 side with this pressing force. Can be transmitted to the member. (2) The second member 130 is composed of a member whose main part has higher rigidity than the first member 120 (hereinafter, may be referred to as “rigid body”), and a fluid member. A member configured to be in close contact with the inner peripheral surface of the cylindrical member 110 is used so as to prevent the movement of the inside of the cylindrical member 110 along the axial direction. Thereby, even if the high pressure is added to the fluid member filled in the cylindrical member 110 between the second member 130 and the fluid member outlet 112 side, the second member 130 is the first member. Since it consists of a main part having higher rigidity than 120, there is no deformation. For this reason, there is no gap between the second member 130 and the inner wall surface of the cylindrical member 110, and as a result, leakage of the fluid member can be suppressed. In addition, the fluid member can be discharged from the fluid member outlet 112 to the outside of the fluid member dispenser 100.

  The second member 130 is composed of a main part having higher rigidity than that of the first member 120, and a cylinder so as to prevent the fluid member from moving in the cylindrical member 110 along the axial direction. If it is the member comprised so that it might closely_contact | adhere with the internal peripheral surface of the shaped member 110, it will not specifically limit. As such a member, for example, a member whose cross-sectional shape is the same as the cross-sectional shape on the inner peripheral side of the cylindrical member 110 and which is configured only from a rigid body such as metal, glass, ceramics, and resin can be cited. However, in a member composed only of a rigid body, the friction with the inner wall surface of the cylindrical member 110 becomes too large, and may not move smoothly in the axial direction. In addition, high dimensional accuracy is required for both the cylindrical member 110 and the second member 130 in order to ensure adhesion to the inner wall surface of the cylindrical member 110. Further, in order to reduce the friction between the second member 130 and the inner wall surface of the cylindrical member 110, a mirror finish may be required. Therefore, as a result, the manufacturing cost of the fluid member dispenser 100 may increase.

  In consideration of such circumstances, the second member 130 includes a columnar rigid member 132 having substantially the same cross-sectional shape as the inner peripheral side of the cylindrical member 110, as illustrated in FIG. The member preferably includes a ring-shaped rubber packing 134 disposed on the outer peripheral surface of the rigid member 132. Here, “substantially the same” means that the cross-sectional shape of the second member 130 is the same as or smaller than the cross-sectional shape of the cylindrical member 110 on the inner peripheral side. . By using the rubber packing 134, the rubber packing 134 and the rigid member 132 and the rubber packing 134 and the inner wall surface of the cylindrical member 110 can be in close contact with each other without any gap. For this reason, the leakage of the fluid member can be suppressed. In addition, since the second member 130 comes into strong contact with the inner wall surface of the cylindrical member 110 via the rubber packing 134 having flexibility, the second member 130 moves inside the cylindrical member. It is easy to move smoothly in the axial direction. Further, the main part of the second member 130 is composed of a rigid member 132. For this reason, when a strong pressure is applied to the second member 130, the second member 130 is deformed, and the fluid member leaks between the second member 130 and the inner wall surface of the cylindrical member 110. There is no gap that leads to

  As illustrated in FIG. 1, the rubber packing 134 may be provided on the outer peripheral surface of the rigid member 132 so as to be provided with a groove on the outer peripheral surface of the rigid member 132. Thereby, the rubber packing 134 can be stably fixed to the outer peripheral surface of the rigid member 132. The material constituting the columnar rigid member 132 can be selected from known rigid materials; that is, metals, glass, ceramics, resins, and composite materials thereof. However, when the second member 130 moves in the axial direction in the cylindrical member 130, the rigid member 132 and the inner wall surface of the cylindrical member 110 come into contact with each other, causing leakage of the fluid member to the inner wall surface. From the viewpoint of preventing the occurrence of scratches, the rigid member 132 is preferably a resin member or a composite member whose outer peripheral portion is made of resin. In addition, as the 2nd member 130 comprised from the resin-made rigid member 132 and rubber packing, piston with rubber packing currently utilized for the fluid member extraction device already marketed illustrated in FIG. May be used.

-Positional relationship between the first member and the second member-
If the first member 120 and the second member 130 are arranged in this order from the opening 114 side to the fluid member spout 112 side, the first member 120 and the second member 130 are arranged in this order. The positional relationship is not particularly limited. And usually, in order to increase the capacity of the fluid member filled between the fluid member outlet 112 side in the cylindrical member 110 and the second member 130 as much as possible, the first member 120, It is preferable that the second member 130 is disposed adjacent to and in contact with each other. In this case, the first member 120 and the second member 130 may be integrally configured by joining both with an adhesive. Further, the first member 120 and the second member 130 may be arranged away from each other with respect to the axial direction of the tubular member 110. However, in this case, a member that does not compressively deform (a member made of a fluid member or a rigid body) is disposed between the first member 120 and the second member 130. If a member that compresses and deforms, such as air, exists between the two members 120 and 130, the pressing force required to pour out the fluid member from the fluid member outlet 112 cannot be transmitted to the second member 130. is there.

-Fluidity member-
A fluid member used when the fluid member is dispensed by the fluid member dispenser 100 (in the example shown in FIG. 1, the tubular member 110 between the fluid member outlet 112 and the second member 130 is filled. As the fluid member, any known fluid member can be used regardless of whether a chemical and / or physical change occurs after dispensing. However, in the case of a fluid member that easily changes chemically and / or physically when exposed to the external environment, if the fluid member is filled in the fluid member dispenser 100, It is easy to suppress such changes. In consideration of this point, as a fluid member, (1) after being discharged to the outside of the fluid member dispenser 100, it is cured by being forcibly given a physical stimulus such as light irradiation or heat treatment. A fluid member, (2) a fluid member that spontaneously cures after being discharged out of the fluid member dispenser 100, such as an oxidation reaction or volatilization of a solvent component, and (3) two types of fluid members It is preferable to use a fluid member that cures by the chemical reaction of or a fluid member that cures using any two or more curing mechanisms of (4) (1) to (3). As an example of such a fluid member, for example, a fluid member of a type in which two fluid members used as a dental composite resin are mixed and cured is used, and as a particularly preferred one, an abutment construction application is used. And dental composite resin used in the above.

  The “fluid member” to be dispensed means a material having fluidity in a temperature environment using the fluid member dispenser 100, and a “pure liquid” consisting only of a solvent component. In addition, a “solution” in which a solid content is dissolved and / or dispersed in a solvent, a “paste”, and the like are also included. The viscosity of the fluid member is not particularly limited, and any fluid member can be used as long as it has fluidity in a temperature environment using the fluid member dispenser 100. However, compared with the case where the conventional fluid member extraction device is used, when the fluid member extraction device 100 is used, damage to the fluid member extraction device 100 is suppressed, and at the same time, the fluid member extraction device is used. In view of the fact that the effect of suppressing the leakage of the fluid member in 100 can be more effectively exhibited, the viscosity of the fluid member is 100 poises in a temperature environment using the fluid member dispenser 100. It is preferably within the range of 10,000 poise, and more preferably within the range of 500 poise to 4000 poise. In the case where the viscosity of the fluid member is less than 100 poise, it is possible to suppress the breakage of the fluid member dispenser 100 and at the same time suppress the leakage of the fluid member in the fluid member dispenser. The merit which uses the fluidity member extraction device 100 instead of the property member extraction device becomes small. On the other hand, when the viscosity of the fluid member exceeds 10,000 poise, the fluidity of the fluid member is too low, and it may be difficult to pour out or become clogged. In addition, in the point which can satisfy | fill the viscosity of the range of 100 poise -10000 poise mentioned above comparatively easily, it is preferable to use a solution rather than a pure liquid, and it is more preferable to use a paste rather than using a solution. Moreover, as a specific example of a paste-like fluid member, for example, a dental composite resin used for an abutment construction application can be given.

-Modification-
Next, a modification of the fluidity member dispenser of the present invention will be described. As illustrated in FIG. 1, the fluid member dispenser of the present invention may be a fluid member dispenser whose main part is composed of only one cylindrical member 110. The cylindrical member 110 described above may be integrally formed. Such a fluidity member dispenser is, for example, a fluidity member that has some utility value by mixing two kinds of fluidity members (for example, by mixing two kinds of fluidity members. It is suitable for use for the purpose of dispensing a fluid member that undergoes a curing reaction. As such a fluid member dispenser, practically, a cylindrical member in which a first member and a second member are arranged in this order from the opening to the fluid member outlet is provided. The first cylindrical member and the second cylindrical member are arranged adjacent to each other so that their axial directions are parallel to each other, and the first cylindrical member is It is particularly preferred that the fluid member outlet and the opening of the second tubular member are arranged on the same side (hereinafter, the fluid member dispenser of this aspect is referred to as “double Sometimes referred to as “pourable fluidity material dispenser”).

FIG. 2 is a schematic diagram showing another example of the fluidity member dispenser of the present invention. In the figure, members having the same functions and structures as those shown in FIG. It is. 2 has a structure in which the two fluid member extractors 100 shown in FIG. 1 are connected in parallel, and each has the same structure as the cylindrical member 110. -It is comprised from the 1st cylindrical member 110A with a function, and the 2nd cylindrical member 110B. And in these two cylindrical members 110A and 110B, the 1st member 120 and the 2nd member 130 are arrange | positioned similarly to the fluid member extraction device 100. FIG.
In addition, as shown in FIG. 2, the fluidity member outlet 112 provided in the first cylindrical members 110A and 110B may be provided at a position close to the joint portion between the two cylindrical members 110A and 110B. . Further, in the drawing, a flange (not shown) may be provided in the vertical direction of the drawing in FIG. 2 on the opening 114 side of the cylindrical members 110A and 110B, for example.

  In addition, in the double pouring type fluid member pouring device as illustrated in FIG. 2, it is preferable that the two pouring members can be poured onto the pouring target in a mixed state. For this reason, you may attach the mixer which covers two fluidity | fluid member pouring outlets to the fluidity | fluidity member pouring outlet side of a double pouring type fluidity member pouring device. As such a mixer, a known one can be used, for example, a mixer disclosed in JP-T-2008-504955 (for example, FIG. 8 etc.) can be used. Furthermore, in order to make the pouring work easier, a tube (so-called guide tip) bent obliquely with respect to the axial direction of the cylindrical member constituting the fluid member pouring device at the tip of the mixer May be attached. In addition, when such adapters are attached to the flowable member dispensers 100 and 102 of the present invention illustrated in FIGS. 1 and 2, the pressure loss from the flowable member discharge port to the opening of the adapter may increase. In the case of using a fluid member of the type that mixes and cures two kinds of fluid members in the fluid member dispenser 102 of the type illustrated in FIG. 2, the curing reaction occurs in the process of passing through the adapter. It will start and the viscosity will increase further. In such a case, with a conventional fluid member dispenser, a higher pressure is applied to the fluid member filled in the fluid member dispenser. The breaker is more likely to break. However, in the fluid member dispenser of the present invention, such a problem can be suppressed even when an adapter is attached to the fluid member dispenser.

-Fluidity material pouring method-
Next, the flowable member dispensing method of the present invention will be described. When dispensing with the fluid member dispenser of the present invention, the tubular member 110 is first filled with the fluid member. The method of filling the fluid member is not particularly limited. For example, the fluid member is moved through the fluid member outlet 112 by moving the second member 130 from the fluid member outlet 112 to the opening 114. In the method of sucking into the cylindrical member 110, the fluid member is filled from the inlet 112 while the second member 130 is pushed in the vicinity of the fluid member outlet 112, and the second member 130 is moved to the opening 114 side. A method of pushing up, a method of filling the fluid member in the cylindrical member 110, and pushing the second member 130 from the opening 114 side can be used.

  Next, the pushing member is inserted from the opening 114 side, and the first member 120 is pressed toward the fluid member spout 112 side. At this time, the first member 120 is deformed so as to contract in the axial direction, and at the same time presses the second member 130. Then, the second member 130 increases the pressure of the fluid member filled in the cylindrical member between the second member 130 and the fluid member outlet 112 side, and the fluid member becomes fluid. It is discharged from the member outlet 112 side.

  The flowable member pouring method described above can be carried out by directly extruding the extruding members 310 and 312 by hand using an extruder 300 as illustrated in FIG. Further, the extruding members 310 and 312 can be extruded by using mechanical force, or by extruding by using the principle of wrinkles even when using hands. As an extruder using the principle of cocoon, it has a columnar extrusion member having a cross-sectional shape that can be inserted into a hollow part of a tubular member of a fluidity member dispenser, and a manual lever. An extruder (for example, the extruder 400 illustrated in FIG. 8) having an extrusion member extrusion mechanism that converts the extrusion member into an operation of extruding the extrusion member in the axial direction by using the principle of scissors can be used.

  When using an extruder using such a manual lever, first, the fluid member in which the fluid member is filled between the extruder and the fluid member outlet side in the cylindrical member and the second member. The tip of the extruding member was inserted from the opening of the flowable member pouring device so that the axial direction of the extruding member and the axial direction of the tubular member of the flowable member pouring device coincided with each other. Fix each other in a state. The fixing method in this case is not particularly limited, but as illustrated in FIGS. 6 and 8, a flange is provided on the opening side of the fluidity member extractor, and an insertion hole corresponding to the flange is provided in the extruder. If a flange is provided, the fluidity member dispenser and the extruder can be fixed by inserting the flange into the insertion hole. Subsequently, by operating the manual lever and extruding the extruding member from the opening side of the cylindrical member toward the fluid member outlet port, the fluid member is discharged from the fluid member outlet into the fluid member dispenser. Can be poured out outside.

-Extrusion member extrusion mechanism-
The pushing member pushing mechanism for converting the movement of the manual lever into the pushing action of the pushing member in the axial direction by using the principle of scissors is not particularly limited. For example, the pusher shown in FIG. As an extruding member extruding mechanism used for 400, the one exemplified in FIG. 3 can be cited as an example. FIG. 3 is an enlarged schematic diagram of the inside of the main body 410 of the extruder 400 shown in FIG. A saw blade-like convex portion 422 is provided on the lower surface side of the pushing member 420 shown in FIG. The convex portion 422 includes a surface 422A perpendicular to the extrusion direction P of the extrusion member 420, and a surface 422B inclined obliquely from the top of the convex portion 422 to the extrusion direction P side. A transmission member 460 for transmitting the movement of the manual lever tip 442 when the manual lever 440 is gripped to the pushing member 420 is converted to a movement in the pushing direction P and transmitted. .

  The transmission member 460 is rotatably attached to the manual lever tip 442 by a support shaft 472. In addition, the transmission member tip 462 of the transmission member 460 (the tip of the transmission member 460 on the push direction P side with respect to the support shaft 472) is always moved by an unillustrated spring member to the arrow U in the figure. A force is acting in the direction (upward direction). For this reason, the transmission member front-end | tip part 462 is contacting so that the lower surface side of the extrusion member 420 may always be pushed up. When the manual lever 440 is not operated, the transmission member tip 462 is in contact with the vertical surface 422A of the convex portion 422. Further, the manual lever tip 442 is fixed to the main body 410 by a support shaft 470 provided below the support shaft 472 and is rotatable about the support shaft 470. The manual lever tip 442 is always applied with a force in the direction of arrow R (the direction opposite to the pushing direction P) in the drawing by a spring member (not shown). Therefore, when the manual lever 440 is gripped and then released, the manual lever 440 can automatically move away from the grip 430 and return to its original position.

  In the push-out member push-out mechanism shown in FIG. 3, first, the manual lever tip 442 moves in the push-out direction P by grasping the manual lever 440. Along with this, the transmission member 460 also moves in the extrusion direction P. At this time, the transmission member front end portion 462 pushes the vertical surface 422A of the convex portion 422 in the extrusion direction P, so that the extrusion member 420 moves in the extrusion direction P. When the manual lever 440 is released, the manual lever tip 422 automatically moves in the direction of arrow R, so that the transmission member 460 also moves in the direction of arrow R at the same time. At this time, the transmission member front end portion 462 moves to the right adjacent convex portion 422 (the convex portion on the opposite side to the extrusion direction P) while traveling on the inclined surface 422B of the convex portion 422, and again, the right adjacent convex portion The unit 422 stops in contact with the vertical surface 422A of the part 422.

-Other inventions-
In addition, the present inventors have a case where the pressure applied to the fluid member filled in the tubular member of the fluid member dispenser is higher than that in the case of using a push-type extruder. However, as a method for suppressing the breakage of the fluid member in the fluid member dispenser at the same time as suppressing the breakage of the fluid member dispenser, the fluid member dispenser illustrated in FIG. 1 is exemplified. . However, even when the first member is removed from the fluid member dispenser of the present invention as the fluid member dispenser, the same problem can be solved. In this case, as an extruder to be combined with the flowable member dispenser, it is sufficient that the extrusion member has a function capable of reversibly deforming in the axial direction. That is, the said subject can be solved also by providing the function of the 1st member in the fluid member extraction device of this invention to the extrusion member side of an extruder.

  As the extrusion member in this case, (a) a member (substantially the same as the first member) that can reversibly deform a part of the extrusion member in the axial direction with respect to the axial direction of the extrusion member such as a rubber member or a spring member. A member replaced with a member having an equivalent function, or (b) a tip member (substantially equivalent to the first member) that can be reversibly deformed with respect to the axial direction of the push member at the tip of the push member. A member having a function) can be used. In any of the above-described embodiments (a) and (b), at the time of dispensing, the first member is substantially the same as the fluid member dispenser of the present invention, from the opening to the fluid member outlet. A member having an equivalent function and a columnar member having a function substantially equivalent to that of the second member are arranged in this order on the axis of the cylindrical member. Therefore, in this case as well, it is possible to dispense without operating the extruder strongly by hand, and it is possible to suppress breakage of the fluid member dispenser and leakage of the fluid member. Moreover, in the aspect (b), the tip part member which has a function substantially equivalent to a 1st member is also arrange | positioned in a cylindrical member at the time of extraction | pouring. For this reason, even if the tip member is deformed by receiving a pressing force, the outer peripheral side of the tip member is surrounded by the inner wall surface of the tubular member, so that the deformation is limited in the axial direction of the tubular member. . Therefore, even if the pushing member is deformed in the axial direction when a pressing force is applied, the pushing member of the mode (b) is less likely to cause shaft wobbling compared to the pushing member of the mode (a), and the stable pouring operation is performed. Is possible.

  FIG. 4 is a top view showing an example of a manual lever type extruder used in another flowable member dispensing method of the present invention, and specifically includes the extrusion member of the above-described aspect (b). It is a figure which shows an example of the manual lever type extruder. FIG. 5 is a schematic diagram showing an example of a fluid member dispenser used in combination with the manual lever type extruder shown in FIG. Extruder 402 shown in FIG. 4 has the same configuration as that of extruder 400 shown in FIG. 8 except that a tip end member 426 is attached to the ends of extrusion portions 422 and 424. The tip end member 426 is formed of a member (for example, a columnar rubber member) having substantially the same function and configuration as the first member 120 shown in FIG. On the other hand, the flowable member dispenser 104 shown in FIG. 5 is configured such that a columnar member 130A is disposed in two cylindrical members 110A and 110B. From the flowable member dispenser 102 shown in FIG. Except for the removal of the first member 120, the fluidic member dispenser 102 has the same configuration. And this columnar member 130A has the same function and structure as the 2nd member 130 used for the fluid member extraction device 102.

  In the case of performing the dispensing by combining the extruder 402 and the fluid member dispenser 104 shown in FIGS. 4 and 5, first, the fluid members are filled into the cylindrical members 110 </ b> A and 110 </ b> B. Next, the extruding portions 422 and 424 of the extruding member 420 are inserted from the side of the opening 114 of the two cylindrical members 110A and 110B, and the columnar member 130A is pressed toward the fluid member spout 112 side. At this time, the two tip end members 426 are deformed so as to shrink in the axial direction in the cylindrical members 110A and 110B, and at the same time press the columnar member 130A. The columnar member 130A increases the pressure of the fluid member filled in the cylindrical member between the columnar member 130A and the fluid member outlet 112, and the fluid member becomes the fluid member outlet 112. It is discharged from the side.
