DETAILED DESCRIPTION OF THE DRAWINGS
[0005] Referring to the Figures 1 to 5 of the accompanying drawings there is shown a container that is particularly envisaged to be used for dispensing of a dental material, in which a front portion of a liquid receptacle is entirely detached from the liquid receptacle.
[0006] Referring to figure 1, there is shown a container 10 in an initial open or storage condition. The dental container 10 comprises a body 12 which has an internal surface 11 and is substantially cylindrical in cross section. Inside the body 12 is an open ended liquid receptacle 14, which is arranged to contain a liquid. The receptacle 14 is sealed by a plunger 18 such as by seal means located on an external surface of the plunger 18 or on an internal surface of the liquid receptacle 14.
[0007] The plunger 18 is initially located in an open end of the receptacle 14 as shown and has a front face 41. Further, as shown the front face 41 of the plunger 18 has extending therefrom a sharp forwardly projecting protrusion 42.
[0008] The body 12 contains a main chamber 17 which is arranged to house an amount of powder. The main chamber of the body 12 is sealed at a distal end 13 by a frangible membrane 22 which is connected to the body 12 such as at an annular inwardly extending flange 23 by any convenient means such as an adhesive. The distal end 13 of the body 12 is opposed to a proximal end 13a thereof. The membrane 22 may be less than 0.01 mm thick. It may also be formed of a single unitary sheet of a plastics material or a multilayer material such as an adhesive/foil membrane material.
[0009] The body 12 has attached thereto an end cap 24 which is connected to a nozzle 26 for dispensing material. The cap 24 is connected to the body 12 by means of a circumferential flange 28 which has an inwardly extending annular rib 30 at an end thereof remote from the nozzle 26. The rib 30 engages with a circumferential recess 32 in the body 12.
[0010] Further, the body 12 is provided with an outward facing circumferential groove 34 adjacent the plunger 18. The groove 34 is arranged to engage with a dispensing apparatus (not shown) in use.
[0011] Still further, the liquid receptacle 14 has a side wall 37 and an inner front portion 36 with a central weakened portion 38. The central weakened portion 38 is substantially thinner than the remainder of the front portion 36 of the liquid receptacle 14. For example the central weakened portion may be a membrane less than 0.01 mm thick. It may also be in the form of a single unitary sheet of plastics material.
[0012] Ajunction between the side wall 37 andthefront portion 36 is defined by an angle 45. The front portion 36 is, in the condition shown in figure 1, spaced from a front face 41 of the plunger 18. Further, the front face 41 of the plunger 18 is provided with the sharp forwardly extending protrusion 42.
[0013] Referring to figure 2, there is shown the container 10 in an activated condition. The activated position is achieved through the plunger 18 being depressed. This action causes the plunger 18 to be moved so that initially the sharp protrusion 42 engages with and then pierces the weakened section 38 of the front portion 36. The plungerthen moves forward until thefrontface41 thereof engages with the front portion 36 and displaces the liquid hydraulically. The liquid is thus forced through a small hole in the weakened section 38 around the protrusion 42 formed by the piercing action into the main chamber 17 of the body 12 by the front face 41. The membrane of the weakened portion 38 remains tightly sealed around the protrusion 42 but is sufficiently flexible to allow the liquid to pass through. This prevents liquid being shaken out of the chamber 17 during mixing. The container 10 may then be placed into a known vibrating mixing device. The liquid and the powder are admixed and thereby form a paste in the chamber 17.
[0014] Referring to figure 3, there is shown the container 10 after the plunger 18 has been depressed and the liquid and the powder have been mixed to form a paste. The main chamber 17 of the body 12 now contains the paste. The front portion 36 of the liquid receptacle 14 has broken away from the remainder of the liquid receptacle 14. This is caused by force being transferred from the front face 41 of the plunger 18 to the front portion 36 of the liquid receptacle 14 during dispensing of the paste with a dispensing apparatus. The sidewall 37 of the liquid receptacle 14 remains substantially intact. The remainder of the liquid receptacle 14 remains in place by virtue of an outwardly projecting annular step 40 on the liquid receptacle 14 engaging with an annular recess 42 in the inner surface 11 of the body 12.
[0015] There is preferably a sharp substantially right angle bend 45 between the front portion 36 and the side wall 37 of the receptacle 14. The bend 45 is preferably devoid of any radius and provides a stress concentration pointto facilitate breaking off of the front portion 36. Force placed on the plunger 18 tends to cause a transfer and concentration of energy at the bend 45 leading to separation of the inner portion 36 at the bend 45 as shown in figure 3.
[0016] As shown in figure 4, the plunger 18 forces the front portion 36 of the liquid receptacle 14 along the main chamber 17, where the front portion 36 of the liquid receptacle 14 acts as a seal and prevents paste from travelling rearwardly. Means such as slots located in the main body internal wall 11 may be provided to act as vent means for entrapped air to escape from the powder. The entrapped air will vent into a recess 44 created from the separation of the front portion 36 of the liquid receptacle 14. The slots may take the form of a plurality of elongated substantially parallel slots 46 which can be seen in figure 6 or other forms.
[0017] Referring to figure 5, there is shown the container 10 once substantially all of the paste has been dispensed. The front portion 36 of the liquid receptacle 14 has been displaced forwardly by the plunger 18 until it approaches the flange 23 of the body 12. As the plunger 18 is displaced forwardly hydraulic pressure on the paste bursts the membrane 22, allowing fluid communication between the main chamber 17 and the nozzle 26 and subsequent dispensing of the paste to a desired location.
[0018] Referring to Figure 7, there is shown a cross section of a preferred embodiment of thesharp protrusion 42 shown in figures 1 to 5.
[0019] It can be seen that the protrusion 42 comprises a head 70 for engagement with a rear face of the inner wall 36. A shaft 72 projects longitudinally from the head 70 and extends through the inner wall 36. The shaft 72 at A may be from 3 to 7 mm long preferably about 4 mm. The shaft 72 has a sharp point 74 remote from the head 70.
[0020] The shaft 72 may be from 0.3mm to 2 mm wide at A where it joins the head 70, preferably about 0.7 mm. The shaft may have zero taper but it can taper inwardly preferably in the range from 0.1 to 6 degrees. The shaft 72 preferably has a width from 0.2 mm to 1.6 mm adjacent the point 74 at B. The point 74 has an angled face 76 which has a side wall which terminates at an outer end of the point 74 at a sharp outer end 78 such that the angle C is preferably less than 90°, preferably from 60-70°. Thus, the point 74 may be conical or it may be an oblique cone. The base of the point 74 may be square or any other convenient shape.
[0021] In figure 8 there is shown a first alternative embodiment of sharp protrusion 42 from that shown in figure 7 and like reference numerals denote like parts.
[0022] In figure 8 the sharp protrusion 42 is embedded in the plunger 18 at the time the plunger 8 is produced. The sharp protrusion 42 may be a polymer coated metal pin having an outer taper to produce a sharp point 74 having a sharp outer end 78.
[0023] In figure 9 there is shown a second alternative embodiment of sharp protrusion 42 from that shown in figure 7 and like reference numerals denote like parts. In this embodiment the sharp point 74 is produced by forming a wedge 80 having a sharp outer end 82.
[0024] Preferably in the embodiments of figures 8 and 9, the metal pins described have diameters in the range from 0.1 to 0.5mm preferably about 0.3mm [0025] In use, a user holds the container 10 and places the plunger 18 onto a flat surface, such as a table, to transfer application of pressure to the plunger 18. Pressure applied to the plunger 18 causes the plunger 18 to move forward and the protrusion 42 to break through the weakened portion 38. The liquid 16 then enters the main chamber 17. The plunger 18 is then displaced forward again by the dispensing device. This brings the frontface 41 of the plunger 18 into close abutting contact with a rear of the front portion 36.
[0026] The main chamber 17 now contains the liquid and the powder. The user then places the container 10 in an appropriate mixing device such as a vibration mixer. The agitation caused by the mixing device causes the liquid and the powder to mix and combine to form a paste.
[0027] After mixing, further forward displacement of the plunger 18 places increasing pressure against the liquid receptacle 14. Once sufficient force is applied the front portion 36 of the liquid receptacle 14 breaks away as shown in figures 3 and 4. This leaves the side wall 37 of the liquid receptacle 14 substantially intact.
[0028] As the plunger 18 is displaced forward slots 46 in the interior surface 11 of the main chamber 17 may allow for any air trapped within the container 10 or mixed material to vent into the recess 44 created from the separation of the front portion 36 of the liquid receptacle 14 from the side wall 37. Further, it is possible that the mixing process does not fully mix all of the powder components and some residual powder is left behind in, for example, the area between the front portion 36 of the liquid receptacle 14 and the internal wall 11 of the body 12. This in practice may cause the dental material to become contaminated by a residual powder component. As the plunger 18 and the front portion 36 move forward the recess 44 is formed behind the front portion 36. Powder particles that have remained unmixed are able to enter the recess 44 hence reducing the risk of contamination or exposure of the user of these particles.
[0029] Further forward displacement of the plunger 18 will cause the plunger 18 to travel to the distal end of the body 12 as show in figure 5. This will lead to increased hydraulic pressure against the frangible membrane 22. Once the hydraulic pressure reaches a critical value the membrane 22 will burst. The paste 28 is thus placed in fluid communication with the nozzle 26. Still further, forward displacement of the plunger 18, as shown in figure 5, will cause the paste 28 to travel through the nozzle 26 before finally being dispensed.
[0030] In the accompanying drawings there is shown the container 10 has an internal surface 11 with an internal step 62 such that the proximal end 13a of the body 12 is of larger dimension than the distal end 13.
[0031] Further the sidewall 37 of the receptacle is provided with an open sided annular recess 64 adjacent the inner portion 36.
[0032] As can be seen the arrangement of the recess 64 and the step 62 enables the receptacle 14 to have a thin section 66 adjacent the inner portion 36. Thus, when force is applied to the plunger 18 as described hereinabove, the inner portion 36 breaks free of the receptacle 14 as shown in figure 3 at the thin section 66. This is because the section 66 is relatively weak compared to the inner portion36. Also, because the distal end 13 of the chamber 16 is smaller in internal diameter than the proximal end portion 13a, all of the force applied to the plunger 18 is concentrated at the step 62 and the thin section 66. Thus, the inner wall 36 breaks away as described above, in use.
[0033] It can also be sent that the main chamber has an optional compression zone 70 adjacent the distal end 13 thereof. The compression zone comprises a step 72. Preferably a proximal face of the step 72 is tapered to provide a smooth transition from the main part of the inner wall 11 and the compression zone 70. The compression zone 70 provides a degree of resistance to the movement of the front portion 36 during extrusion of the material.
[0034] Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention as defined in the appended claims.
