Abstract
The invention relates to a cartridge for receiving pasty dental material, comprising a substantially cylindrical container whose front end is delimited by a front part having an outlet for the pasty dental material and whose second front end is open and wherein a piston that is movable in longitudinal direction is arranged. In order to enable effective filling of said cartridges with the pasty dental material while preventing contamination of the filling installation and minimizing losses of dental material during the filling process, the front part has at least two outlets embodied as tubular projections.
Description
The present invention relates to a kind ofly have one and be essentially tube for feed cylindrical vessel, that be used for adorning the paste dental material, one end of container is defined by a front portion that has the outlet of paste dental material, second end of container then is open, and arranges a piston that can longitudinally move therein.
For example from the known this tube for feed of German patent DE 3322343A1.This tube for feed has a sizable volume, and is used for adorning the vessel of for example making artificial tooth.For this reason, the discharge gate of tube for feed is attached on these vessel, and the artificial tooth material is clamp-oned in the vessel by means of a worm screw that acts on the piston.This tube for feed is applicable to be extruded its content with one form.
In dentist's office, use so-called syringe more and more, this syringe is the small-sized tube for feed of 1 cubic centimetre of volume, the dental synthetic material can directly be put into the position that requires in patient oral cavity from tube.The suitable complex apparatus fill in enormous quantities that this syringe is formed with bulk container.This bulk container needs quite high cleaning cost, forms one because this bulk container is fixing and corresponding filling machine, and in this equipment, Once you begin pouring process just must proceed to till the magazine emptying, as far as possible in order to avoid material unaccounted-for (MUF).
The objective of the invention is to, propose a kind of tube for feed and adorn the so-called syringe of paste dental material effectively, avoid filling apparatus to pollute and make in the pouring process dental material unaccounted-for (MUF) minimum simultaneously.
According to this tube for feed of the present invention, this purpose is achieved in that the front portion has at least two discharge openings, and this discharge opening is made pipe joint.Can be with this tube for feed at least with two this so-called syringes of fashionable dress.For this reason, tube for feed is connected on the jumper bar, and this jumper bar is clamp-oned dental material in the syringe by means of piston.The quantity of the syringe of fill simultaneously can realize by arrange a plurality of tube for feed simultaneously at a plurality of discharging openings of equipment on the tube for feed or on by the extruding device of being furnished with corresponding jumper bar number at one.The advantage of this tube for feed is, dental material can directly be packed in the tube for feed after making and be preserved in tube for feed, and is not subjected to the restriction of device for casting capacity, and device for casting is not contaminated.Even it is not contaminated in the pouring process of fill syringe itself yet.Tube for feed can be made and use as non-returnable container with inexpensive plastics.After use, tube for feed is recyclable or carry out industrial clean, so tube for feed is suitable for recycling.
Pipe joint preferably is symmetrical in the Cylindorical rod of container and arranges.Particularly, pipe joint can be made cylindrical shape, and at it on an end of container, the outer surface of pipe joint is along the tapered expansion of container direction.A kind of favourable structural shape of this conical expansion is made up of two parts conical expansion that front and back are provided with.This conical expansion makes pipe joint increase rigidity and tube for feed is accurately centered on filling apparatus, thereby the function of guaranteeing tube for feed is intact.This conical expansion also has certain protective action to the mechanicals efforts in the transportation for example.
Be preferably in and arrange an annular seal lip on the circumference of tube for feed piston, the sealing lockjaw is attached on the container inner wall and from piston extends along forward direction.Like this, when piston pushed in the container, dental material blew off from barrel, so dental material is fully utilized.In addition, piston preferably has a cavity.Secondly, this piston preferably has such circumferential surface, and promptly this circumferential surface can be close on the container inner wall and be arranged between second opening end of sealing lip and container, so just can guarantee the high stability of container inner carrier.In addition, in order to seal container contents and to avoid for example accidental movement of piston, it also is very necessary that a removable lid is set on second opening end of container.In addition, forwardly go up the preferably additional over cap that is provided with.
Describe one embodiment of the present of invention in detail below in conjunction with accompanying drawing.
Accompanying drawing is represented:
The vertical section of the tube for feed of the present invention of Fig. 1 band cover;
The vertical view of Fig. 1 a tube for feed;
The sectional drawing of Fig. 2 piston;
The vertical view of Fig. 2 a piston.
Tube for feed has the cylindrical vessel 1 of a band cylindrical shape transverse section.One end of this container is by 2 sealings of a front portion, and two discharge gates are symmetrical in Cylindorical rod and are arranged on this front portion.Discharge gate is made and is similarly columnar pipe joint 3.This pipe joint is connected anterior 2 external peripheral surface towards the tapered expansion in this front portion.This cone 4 has been guaranteed tube for feed centering accurately and the enough rigidity during the tube for feed carrying on filling apparatus, in order to avoid pipe joint 3 damages or fractures.This conical expansion is made up of two parts expansion that front and back are provided with.Anterior 2 outwards arch upward a little.
The rear end of container 1 can 5 cover with a lid, after the tube for feed fill until before using, this lid all is worn on the container 1 and shields.Piston 6 is arranged on the inside of container 1, can vertically move along it.Piston 6 has a front side 7, and its shape matches with anterior 2 inboard, so that extrude the material in the container 1 as far as possible fully.On the circumference of piston 6, be provided with a sealing lip 8 on every side along it, the sealing lockjaw is attached on the container inner wall.Sealing lip 8 promptly extends and the effect of scraper when piston 6 pushes container 1 to the direction of the front portion 2 of tube for feed forward from the circumferential surface 11 of piston 6, so adherent surplus material is all wiped off on the wall of container 1.Because this structure of sealing lip and form a cannelure 9 between the circumferential surface 11 of piston 6 and sealing lip 8 can be provided with a through hole on this bottom land, so the vessel of formation is communicated with between the cavity of piston 6 and piston 6 and anterior 2.Look from the front side 7 of piston 6, this piston has a circumferential surface 12 that is arranged in sealing lip 8 back, and this circumferential surface is close on the container inner wall, so stablized the position of the piston 6 in the container 1.
Tube for feed is equipped with a kind of paste dental material and can preserves till the use.Forwardly an over cap 10 is set on 2.This over cap 10 is sealed pipe joint 3, in order to avoid the material in the tube for feed flows out or use follow-up afterflow to lose.In addition, this over cap shields in transportation to pipe joint 3 and pipe joint 3 is played the light blocking effect with interior material (for example a kind of synthetic material cream of photo-hardening).When using tube for feed, its face is connected on the pressurizing unit of filling apparatus from an end of anterior 2, will its jumper bar insert in the cavity of piston 6 and the direction of piston 6 towards anterior 2 promoted.Before this, on each pipe joint, adorn a syringe to be filled, so that dental material is clamp-oned in the pipe.Syringe can be arranged on the anchor clamps and with certain beat by pipeline system and pass through pipe joint 3, so just becomes the many syringes of mechanical fill.
