Description

Oozing free caulking and glueing gun based on vacuum
The present invention relates to a caulking gun for holding a canister with substance 5 therein, to a canister for use in a caulking gun and to a kit comprising the caulking gun and the canister.
As is well-know to both professional construction people and home handyman, so called caulking guns of the type presently available in the marketplace suffer from the problem of over-ejection, colloquially known as oozing, from the nozzle of the caulking canister after 10 pressure on the canister has been removed. Because of such over-ejection of substance, such as for example kit or glue, from the caulking canister, and additional and often time-consuming step is typically added to the caulking process.
Particularly substances having a viscosity between 2 and 10A5 mPa-s suffer from this problem. The known method of creating a vacuum in the canister by pulling back the ejection 15 member is not enough for these kinds of substances. Due to the relatively low viscosity large amounts of substance come out of the nozzle after the pressure has been released.
It is an object of the present invention to overcome the above mentioned problems with the traditional caulking guns and canister.
A first aspect of the present invention relates to a caulking gun for applying substances 20 having a viscosity between 2 and 10A5 mPa s, which caulking/glueing gun comprises a body for holding a canister, an ejection member passing through the body and spring means, wherein the ejection member is positioned adjacent to a first clamping plate for pushing the ejection member forwards through the body and wherein the ejection member is positioned adjacent to a second clamping plate for pulling the ejection member backwards trough the 25 body and wherein the spring means are positioned in between the clamping plates.
Preferably, the spring means are positioned around the ejection member. It is further preferred to provide the clamping plates with handles for operating them. The use of handles, which are connected with the clamping plates, make it easier for the operator to operate the caulking/glueing gun.
30 In a further embodiment of the invention the ejection member comprises a push plate, which push plate is provided with securing means for securing the push plate with a moveable plunger of a canister. A push plate is particularly useful because it divides the pressure asserted on the moveable plunger of the container. One also avoid that the ejection member is 1 0 38 8 67 2 misaligned and is pushed through the wall of the canister. A preferred way of attaching the push plate to the plunger of the canister is by way of magnets.
For holding the canister the body of the caulking/glueing gun is preferably provided with clamping means. Specially preferred clamping means are so called umbrella clamping 5 means.
A second aspect of the present invention relates to a canister for use in a caulking/glueing gun comprising an inlet and an outlet, wherein in the inlet a moveable plunger is provided for pushing out of the canister a substance having a viscosity between 2 and 10A5, and wherein the outlet is provided with a nozzle, which nozzle is provided with a 10 closure membrane which comprises a closure head wherein at least one head plate ring is formed on the closure head, preferably around its border which extend essentially perpendicular with respect to the plane of the closure head. Because of the ability of the membrane to have two stable positions which are created by the caulking/glueing and the pulling back, the outward flow is not limited and the over-ejection is stopped when the 15 plunger of the canister is released/pulled back.
Preferably, the head plate ring is formed on the outer surface of the closure head, preferably in the form of an annular projection unitary with the closure head. It is particularly preferred when the head plate ring is dimensioned in such a way to produce specific restoring forces when the closure head with the head plate ring is deformed. This results in reduction of 20 over-ejection and reduces dehydration of the contents of the canister.
In a preferred embodiment the moveable plunger of the canister is provided with securing means for securing the moveable plunger with a push plate of a caulking/glueing gun. This way the moveable plunger of the canister will move in the same direction as the ejection member and the push plate connected thereto. This way it is possible to create a 25 vacuum in the canister after the ejection member is pulled back by the second clamping plate.
In the same embodiment the push-rod of the caulking/glueing gun will actively be pulled back by a device such as a spring, elastic body or fluid or gas reservoir when the caulking/glueing force is stopped and the handles are released.
In another embodiment the nozzle is integrated in the canister. This will make the 30 canister easier to use and less expensive to produce.
A third aspect of the present invention relates to a kit comprising a caulking/glueing gun as described above and a canister as described above. It is particularly preferred that the securing means of the push plate of the caulking/glueing gun are compatible with securing means of the moveable plunger of the canister. This way the plunger and the push plate will, 3 in operation and after having been attached with each other, move in the same direction. The securing means used preferably comprise magnets, threading, umbrella clamping, diaphragm, vacuum and bayonet joint.
In operation the canister is attached to the body of the caulking/glueing gun. By 5 operating the first clamping means the ejection member will be pushed forwards into the inlet of the canister. At a certain point the ejection member will reach the moveable plunger of the canister. If the first clamping plate is operated further the ejection member will push the plunger of the canister further into the canister and consequently substance such as glue will be forced out of the canister. When enough substance has left the canister the operator will no 10 longer use the first clamping plate to push the ejection member further. Instead, he will start to operate the second clamping means. Because the moveable plunger is secured to the ejection member, for example by magnets, both the ejection member and the plunger of the canister are pulled back and a partial vacuum is created in the canister. Due to this vacuum the dripping of substance from the outlet of the canister will stop or become less.
15 However, as indicated above, if a substance, such as wood-glue, is used with a relatively low viscosity the substance will still drip out of the canister. In order to avoid this the nozzle of the canister is provided with a closure membrane which comprises a closure head wherein at least one head plate ring is formed on the closure head, preferably around its border which extend essentially perpendicular with respect to the plane of the closure head.
20 Only after a vacuum has been created in the canister the membrane closes. It is thus of importance that in operation the moveable plunger of the canister is pulled back such that this vacuum is created. In a preferred embodiment the head plate ring is formed on the outer surface of the closure head, preferably in the form of an annular projection unitary with the closure head. It is further preferred that the head plate ring is dimensioned in such a way to 25 produce specific restoring forces when the closure head with the head plate ring is deformed.
The invention will be further elucidated by the following non limiting examples: 1. Canister 5. Push-clampingplate 10. Spring 2. Caulking/glueing gun 6. Push-handle 11. Content 26 body 7. Turning-knob 12. Pull-vacuum and cartridge 3. Push-rod 8. Push-plate release handle 4. Pull-clampingplate 9. Plunger 13. Closing membrane 14. Nozzle 4
Figure 1 to 4 show a caulking/glueing gun provided with a canister (2) according to the invention. The caulking/glueing gun comprises a body (3) and an ejection member (4). In this embodiment the ejection member is formed by a rod which extends through the body (3) of the caulking/glueing gun. Within the body (3) of the caulking/glueing gun clamping plates 5 (5) and (6) are provided. The clamping plate (6) is for pushing the ejection member through the body (3) of the caulking/glueing gun. The clamping plate (6) is connected to a handle (7) which makes it easier to move the clamping plate (6) over the ejection member (4). At the back end of the extension member a stop (8) is provided. At the other end of the ejection member a push plate (9) is provided. The push plate (9) is provided with means for securing it 10 with a plunger (10) of the canister. Such seeming means could for example be magnets. When in operation the clamping plate (6) pushes the ejection member further and further through the body (3) of the caulking/glueing gun the push plate (9) will be connected to the plunger (10) of the canister. If the ejection member is further pushed forward substance (12), such as wood glue, will be pushed out of the canister. When the operator decides to stop with the operation 15 clamping plate (5) is operated by means of the handle (13). The clamping plate (5) pulls the ejection member back. Because the push plate (9) is connected to the plunger (10) of the canister (2) a vacuum will be created in the canister (2). This vacuum closes the membrane (14) in the nozzle (15) of the canister. This way even substances, such as liquids, with a relatively low viscosity can be applied on a substrate by means of a caulking/glueing gun.
20
Figure 5 shows in detail the nozzle (15) of the canister (2). At the tip of the nozzle a closure membrane (14) is provided for closing the outlet of the nozzle. If the pressure in the canister (2) is higher than outside the canister (2), the membrane (14) will deform and substance will flow from the canister (2) through the nozzle (15) and the membrane (14) on 25 the substrate (not shown). However, when the plunger is pulled back a vacuum is created and the membrane (14) close the opening in the nozzle and thereby blocking the flow of substance (12) from the canister (2).
The push-rod (4) can move freely. When attached to the plunger (10), the resistance of 30 the plunger (10) in the canister (2) prevents total retraction of the push-rod (4) when the push-handle (7) is released. An automatic vacuum is created by the stored energy in the spring (11) that clamps the push-clampingplate (6) on the push-rod (4) and pushes the push-rod (4) attached to the plunger (10) back. If necessary the pull-handle (13) is used to create an extra vacuum, for example to prevent over-ejection and to suck-out the nozzle (15).
