The shortcoming of compressing the outlet of one of them blow molding part is, the flow section of outlet dwindles and must just open and increase by the ejection composition.When lid screwed out back ejection beginning, the mixture ratio of composition may undesirably be changed.
Summary of the invention
The objective of the invention is a kind of multi-component cartridge of suggestion, it does not compress the outlet of composition when sealing.
For this reason, the present invention proposes a kind of multi-component cartridge, be used for preparing jointly multiple composition, they leave in the multi-component cartridge with being isolated from each other, comprise a pipe-type outlet, the inside outlet of a tubulose is in wherein, and comprise a seal section that can be spun in the outlet, can seal outlet by it, it is characterized by: seal section has an interception conveyor screw, when seal section is spun on outlet when going up, inner outlet rests on the interception conveyor screw inboard, and it feels relieved inner outlet in the interception conveyor screw when further screwing.
This shows the inside outlet of being in of the externally ported of a tubulose and a tubulose in externally ported arranged by multi-component cartridge of the present invention.The externally ported while also can be cartridge case outlet, and cartridge case also can be one of container simultaneously, thereby only needs one to insert the interior container of cartridge case with cartridge case separates.In order to seal, multi-component cartridge has the closed section that can be spun on externally ported, for example a screw top or a spiral cover.Seal section has an interception conveyor screw that is used for inner outlet.When seal section was spun on externally ported going up, inner outlet rested on the interception conveyor screw inboard, and it feels relieved inner outlet in the interception conveyor screw when closed section further screws.When screwing on closed section, the hurdle cuts conveyor screw makes inner outlet directed, thereby makes the a/s orientation of inner outlet rest on one of interception conveyor screw in-to-in for example on the sealing surface of closed section, and is sealed shut thus.Thereby can be sealed shut inner outlet, need not to compress this inner outlet.Externally ported for example by common mode by closely resting in the closed section or closed section back seal ground sealing.Advantage of the present invention is that it is the outside and the inner outlet of deadend multi-component cartridge airtightly, need not to compress one of them outlet.
Preferably design by the present invention, the interception conveyor screw has a pitch.That is to say that it relates to the combination of a spiral shell family and a screw thread.Inside exports thereby at first rests on the spirochetal major diameter of interception, and outlet still has axial distance from inside and tackle the less diameter of conveyor screw this moment.Improve inner outlet described " interception " thus.
By a design of the present invention, a plug is arranged at interception conveyor screw center.When seal section is spun on outlet when going up, the interception conveyor screw makes inner outlet be positioned at the plug center.Plug enters in the inner outlet and a mouth that exports by inside abuts in plug outside face back seal.Plug for example is a cone, and its outside face can be outwards arched, that is is spherical or also can is hollow circle.
Description of drawings
The embodiment that represents by accompanying drawing describes the present invention in detail below.Wherein:
Fig. 1 is by the part of multi-component cartridge forward region of the present invention; And
Multi-component cartridge enclosure portion inside perspective view among Fig. 2 Fig. 1.
The specific embodiment
Shown in Figure 1ly be designed to tubulose by multi-component cartridge 1 of the present invention.Its front end in the drawings has an orifice plate shape end wall 2 that has the pipe-type outlet 3 that is shaped on outside thread 4.This multi-component cartridge 1 constitutes external container 5, wherein inserts an internal container 6.Internal container 6 is blow molding parts.These two containers 5,6 contain a kind of composition in the bi-component material respectively, for example a kind of adhesive and a kind of hardener, and they leave in the cartridge case 1 with being isolated from each other.Therefore in the embodiment of diagram and explanation, multi-component cartridge 1 is an a kind of pair of composition cartridge case.In order to spray these compositions, in-to-in container 6 can axial compression.The piston that does not have expression among the figure by the spray gun that does not have expression among the figure can be with outlet 3 ejections of composition from cartridge case 1, and these compositions are mixing after cure.The cross-sectional plane of container 5,6 is vertically constant along two composition cartridge cases 1, the mixture ratio of composition when the ratio of container 5,6 cross-sectional planes has determined ejection.
Also follow the cartridge case 2 that filling constitutes external container 5 by inserting a good new internal container 6 of filling, can fill this multi-component cartridge 1 again.Internal container 6 has a tubulose (hereinafter claiming in-to-in) outlet 8, and it is in the outlet 3 of cartridge case 1 and reaches in the oral region of multi-component cartridge 1 outlet 3 always.
In order to seal this multi-component cartridge 1, will be spun on the screw thread 4 of outlet 3 for the closed section of capping 9 in form.Fig. 2 has represented capping 9 in detail.One of capping 9 section is spun in the outlet 3 dearly in Fig. 1.Capping 9 has the sealing cantilever 11 of an internal conical surface 10 and an annular, and when capping 9 screwed on fully, the mouth of multi-component cartridge 1 outlet 3 entered between them.Internal conical surface 10 and sealing cantilever 11 constitute sealing arrangement, and when capping 9 screwed on fully, the tight-lipped of outlet 3 thickly abutted between them, thereby seals multi-component cartridge 1 airtightly.
The capping 9 that constitutes closed section has an interception conveyor screw 12 at inside outlet 8.Interception conveyor screw 12 is helix strip components, and it parallels to the axis and stretches out more than whole circle of also helix ground extension from capping 9 inboards.Interception conveyor screw 12 has a pitch, that is to say, its end limit 13 is also shape of threads extension except helix.At interception conveyor screw 12 centers, capping 9 has a conical plug 14.
When the capping 9 that constitutes closed section was spun in the outlet 3 of multi-component cartridge 1, the outlet of the inside of internal container 6 rested on the inboard of interception conveyor screw 12 as seen from Figure 1.Even this situation occurs in as shown in Figure 1 under the situation that inner outlet 8 offsets prejudicially towards the side.When further screwing capping 9, interception conveyor screw 12 makes outlet 8 capping 9 central motions towards plug 14 positions based on its helix.When capping 9 continued to screw, plug 14 entered in the in-to-in outlet 8 and closely rests on its mouthful.Therefore, internal container 6 seals equally airtightly, protects two kinds of compositions in two containers 5,6 to prevent that them from becoming dry.By with plug 14 sealing, make inner outlet 8 when sealing not by compression, thereby when opening, that is after capping 9 was screwed out, two outlets 7,8 had their complete cross-sectional planes.When being spun on capping 9 on the multi-component cartridge 1, interception conveyor screw 12 makes inner outlet 8 with respect to plug 14 centering, that is to say, interception conveyor screw 12 guarantees that when screwing on capping 9 as prescribed enters in the mouth of inner outlet 8 and with it plug 14 and is sealed shut.Situation when this is equally applicable to inner outlet shown in Figure 18 and offsets towards the side.
