Abstract

A device for applying adhesive and/or sealant having a housing for receiving a container, said housing having the following: a receiving chamber for receiving the container; a closable application tip which is connected to the receiving chamber and through which the adhesive and/or sealant can be discharged; a stable casing for the receiving chamber; at least one region of the housing which is in the form of a deformable pressure region and which allows pressure to be exerted from the outside onto the container which can be placed in the receiving chamber.

First claim

The invention claimed is:

1. A device for applying adhesive and/or sealant, comprising:
a rigid housing for receiving a tapered container, wherein the housing has an application end, a longitudinally opposing extended grip region having an end and a medial portion positioned approximately midway between the application end and the extended grip region end, and the housing comprises:
a tapered receiving space defined within the rigid housing for receiving the tapered container so that a closed end of the container defines the medial portion position, wherein the receiving space is narrower adjacent the medial portion and wider adjacent the application end;
a closable application tip adjacent the application end which is connected to the receiving space and through which the adhesive and/or sealant can be discharged;
at least one region of the housing between the medial portion and the application end being a deformable pressure region having an outside surface, an opposing inside surface that can directly contact the container and at least one movable region which is connected adjacent the application end of the rigid housing by a zone having increased deformability, wherein the zone having increased deformability is formed by the material of the pressure region in said zone being depressed such that it is inverted when the movable region is pushed in and allows the movable region to move against the remainder of the housing that surrounds the movable region and pressure exerted on the outside surface forces the inside surface into contact with the container in the receiving space.

2. The device according to claim 1 , wherein the pressure region comprises a deformable material connecting a periphery of the pressure region to the rigid housing.

3. The device according to claim 1 , wherein the zone having increased deformability is an elastomeric material.

4. The device according to claim 1 , wherein the zone having increased deformability comprises a material that can be more easily deformed.

5. The device according to claim 1 , wherein the at least one pressure region comprises an upper face and a lower face, wherein the upper face is exposed on the surface of the housing and the lower face faces a stable movable structure which defines the receiving space below the at least one pressure region.

6. The device according to claim 1 , wherein the tapered receiving space does not extend into the extended grip region.

7. The device according to claim 6 , wherein the extended grip region is made of the same material as the rigid housing.

8. The device according to claim 6 , wherein a second container is received in the extended grip region.

9. A device for a user to apply adhesive and/or sealant to a surface, including:
a rigid housing having
an application end,
an extended grip end longitudinally opposing the application end,
a first side defining a pressure region near the application end, a grip region near the extended grip end, and a medial portion between the application end and the extended grip end, the pressure region having an exterior surface, an opposing interior surface and an elastomeric connection to the rigid housing, the pressure region being displaceable inwardly by the user from a neutral position toward a dispensing position, the grip region not being displaceable by the user,
a second side opposing the first side,
a third side connecting the first and second sides and
a fourth side opposing the third side, the fourth side connecting the first and second sides,
the housing sides defining a tapered internal cavity, the internal cavity having a receiving space adjacent the pressure region to hold a deformable container of adhesive and/or sealant having opposing tapered sides in direct contact with the interior surface of the pressure region, wherein a tapered side of the container is in direct contact with the interior surface of the pressure region, the receiving space having a connector for fluidly receiving adhesive and/or sealant from the deformable container,

an applicator at the application end having an application tip and defining an internal conduit fluidly connecting the connector to the application tip;
wherein user movement of the pressure region inwardly from the neutral position toward the dispensing position presses the interior surface against the container of adhesive and/or sealant to displace adhesive and/or sealant through the connector and conduit to the application tip.

10. The device of claim 9 wherein the container is positionable in the receiving space by a user.

11. The device of claim 9 wherein the second side further comprises a pressure region near the application end and a grip region near the extended grip end, the pressure region having an exterior surface and an opposing interior surface and being deformable to allow the user to move the pressure region inward from a neutral position to a dispensing position where the interior surface is in direct contact with the container.

12. The device of claim 9 comprising a cap over the application tip and removably secured to the housing at the application end.

13. The device of claim 9 further comprising a second container disposed within the inner cavity adjacent the grip region, the second container fluidly connected to an application tip adjacent the grip end.

14. The device of claim 9 wherein the first side pressure region comprises an elastomeric material connecting a periphery of the pressure region to the rigid housing.

15. The device according to claim 1 , wherein the tapered receiving space is formed by two transversely opposing arms, wherein the arms are spaced closer adjacent the medial portion and wider adjacent the application end and the arms do not contact each other.

16. The device of claim 9 wherein the tapered internal cavity region does not extend into the extended grip region and the tapered internal cavity is formed by two transversely opposing arms within the pressure region, wherein the arms are spaced closer adjacent the grip region and wider adjacent the application end and the arms do not contact each other.

17. The device of claim 9 wherein the elastomeric connection has an externally facing U shape in the neutral position.

18. The device of claim 9 wherein the elastomeric connection has an externally facing U shape in the neutral position and is inverted out of the U shape in the dispensing position.
