Detailed description of the invention
Referring to figs. 1 to Fig. 5, demonstrate the container specifically imagined and distribute for dental material, wherein the front portion of fountain departs from from fountain.
With reference to figure 1, demonstrate the dentistry container 10 under initial opening or storing state.Dentistry container 10 comprises device body 12, and it has inside face 11 and cross-sectional plane is substantially cylindrical.Have the fountain 14 of one end open in device body 12 inside, it is in use for carrying liquid (not shown).Storage 14 is sealed by plunger 18 (sealing arrangement such as, on the outside face 19 being positioned at plunger 18 or on the inside face 15 of fountain 14).Plunger 18 is arranged in the open end of shown storage 14, and has forward 41.
Device body 12 is containing main chamber 17, and it is in use for placing appropriate pulvis (not shown).Device body 12 is sealed by frangible membrane will 22 at distal end portion 13 place, and this frangible membrane will 22 is connected on device body 12 (such as: be connected to annular by arbitrary convenient tool (as adhesion agent) and extend internally flange 23 place).The distal end portion 13 of device body 12 is relative with its proximal end 13a.Device body 12 is with the end cap 24 with the nozzle 26 be connected to for dispensing materials.By means of the circumferential flange 28 in its one end away from nozzle 26 with the circumferential rib 30 that extends internally, lid 24 is connected to device body 12.In device body 12, rib 30 engages with circumferential recess 32.
Preferably between storage 14 and plunger 18, provide liquid tight seal part (not shown).Described sealing member comprises circumferential rib, and it extends outwardly into plunger 18 from storage 14, and vice versa.
Further, body 12 has outwardly open circumferential groove 34 in plunger 18 vicinity.Groove 34 is for engaging with distributing equipment (not shown) in use.
Further, fountain 14 has sidewall 37 and the inwall 36 with center weakening part 38.Center weakening part 38 is thinner than the remainder of the inwall 36 of fountain 14 by and large.Under state shown in Fig. 1, inwall 36 separates with the front 41 of plunger 18.
With reference to figure 2, demonstrate the container 10 under active position.This active position is obtained by depressing plunger 18, and this racking causes plunger 18 to move its inner is contacted with inwall 36.This makes liquid move so that the weakening part 38 of inwall 36 damages its hydraulic pressure applied due to liquid.Then liquid is pushed in the main chamber 17 of device body 12 and contacts with the pulvis in room 17.Container 10 can be put into known vibration mixing device subsequently.Liquid and pulvis mixing is made also in room 17, to form paste thus.
With reference to figure 3, demonstrate the container 10 after plunger 18 has been pushed and liquid and pulvis mix and form paste.The main chamber 17 of device body 12 is now containing paste.The front portion comprising the fountain 14 of its inwall 36 departs from from the remainder of fountain 14.This is owing to causing utilizing distributing equipment to distribute the power being delivered to the front portion of fountain 14 from plunger 18 in the process of paste.The remainder of fountain 14 relies on outwardly ring ladder 40 on fountain 14 engage (see Fig. 3) with the annular concave seat 42 in the inside face 11 of device body 12 and remain on appropriate location.
As shown in Figure 4, plunger 18 promotes the front portion of fountain 14 along main chamber 17, and wherein the front portion of fountain 14 is played sealing and stoped paste to move backward.Being arranged in the devices such as the such as slit of main body inner wall 11 can through providing to serve as the eduction gear that entrapped air is overflowed from pulvis.Entrapped air can enter in the dimple formed due to the separation of the front portion of fountain 14.Slit can take form or other form of multiple elongated substantial parallel slit 46 (can find out in Fig. 6 or Fig. 7).
Can find out in Fig. 1 to Fig. 5, the inside face of the device body 12 of container 10 has inner step 62 and is greater than distal end portion 13 with the size of the proximal end 13a making device body 12.
Furthermore, the sidewall 37 of storage has the open annular concave seat 64 in side near inwall 36.Dimple 64 engages (as shown in fig. 1) from the beginning with ladder 62.
Can find out, the layout of dimple 64 and ladder 62 makes storage 14 can have thin section 66 near inwall 36.Therefore, when exerting a force to plunger 18 (as described above), inwall 36 departs from (as shown in Figure 3) from storage 14 at thin section 66 place.This is because section 66 is relatively weak compared with inwall 36.In addition, the internal diameter due to the distal end portion 13 of main chamber 17 is less than the internal diameter of proximal end part 13a, and therefore what therefore apply to plunger 18 concentrates on ladder 62 and thin section 66 place effectively, and in use inwall 36 departs from as mentioned above.
With reference to figure 5, demonstrate the container 10 when all pastes distribute substantially all.Move forward the front portion of fountain 14 until its flange 23 close to device body 12 by plunger 18.When moving forward plunger 18, the hydraulic pressure on paste makes film 22 burst, and this permission is carried out fluid transmission and subsequently paste is assigned to desired position between main chamber 17 and nozzle 26.
Can find out, inside face 11 has compression zone, and it comprises the stepped region 50 that cross sectional dimensions reduces, and wherein provides limited resistance to the movement of the front portion disengaging part of fountain 14.Result shows, specifically, by using low viscosity material, the limited resistance provided by ladder 50 reduces the uncontrolled risk extruded of low viscosity material.
Stepped region 50 makes the propelling of the front portion of fountain slow down, and the extruded velocity of described material is also corresponding slows down.The face, nearly portion of stepped region 50 is preferably tapered, to provide from the main portion of inside face 11 and seamlessly transitting of stepped region.
In use, container 10 is put into suitable distribution device (not shown) by arbitrary convenient tool 34 thus is allowed to apply pressure to plunger 18 by user.Make to raise relative to the hydraulic pressure of weakening part 38 to the movement of plunger 18 applied pressure via liquid 16.Once hydraulic pressure reaches transformation point, weakening part 38 just damages, and liquid 16 enters main chamber 17 subsequently.Then, plunger 18 is again moved forward by distribution device.This makes the front 41 of plunger 18 and the adjacent close contact in the back side of inwall 36.
Main chamber 17 is now containing liquid 16 and pulvis 20.Then suitable mixing device (as vibromixer) put into by dental dressings device by user.The stirring caused by mixing device makes liquid and pulvis mix and combine and forms paste.
After mixing, the moving forward further of plunger 18 makes to apply for fountain 14 pressure that increases progressively.Once apply sufficient power, the front portion of fountain 14 just departs from, as shown in Figure 3.This makes sidewall 37 zero damage substantially of fountain 14.
When plunger 18 moves forward, in the dimple that the slit 46 (see Fig. 6 with Fig. 7) in the inside face 11 of main chamber 17 can make container or any air of trapping of the composite material inside front portion entered due to fountain 14 be separated with sidewall 37 and be formed.Furthermore, mixed process may not make all pulvis components mix completely, but leaves some residual pulvis in the region between the front portion and the inwall 11 of device body 12 of (such as) fountain 14.Along with the region by dental material process is subject to the pollution of residual pulvis component, in fact this may throw into question.When plunger 18 and inwall 36 move forward, after inwall 36, form dimple.The powder with unmixed remainder can escape into around anterior and enter in dimple, because this reducing the pollution of these particles or making user be exposed to the risk of these particles.
The distal end portion making plunger 18 towards device body 12 moves by moving forward further of plunger 18, as shown in Figure 5.The hydraulic pressure caused relative to frangible membrane will 22 increases by this.Once hydraulic pressure reaches critical value, film 22 will burst.Therefore, paste 28 is fluidly communicated with nozzle 26 through being placed to.Further, moving forward of plunger 18 will make paste pass nozzle 26, and then finally distribute.But as mentioned above, the existence of ladder 50 provides compression zone, it provides resistance to a certain degree to the front portion of storage 14 from position shown in Fig. 4 to the further movement of position shown in Fig. 5.
The apparent modifications and variations of those skilled in the art are regarded as within the scope of the invention.
