Such a nozzle adapter includes a shoulder portion which has a hole into which a tapered nozzle of the caulking tube is inserted, a header portion which is protruded on the shoulder portion and configured to engage with an external nozzle which the user may select depending on a working environment; and a clutch plate which is provided under the shoulder portion and configured to engage with the tapered nozzle and fix the hole of the shoulder portion at the tapered nozzle. The header portion, the shoulder portion and the clutch plate forms an internal passageway through which the tapered nozzle is inserted and a caulking material flow from the tapered nozzle of the caulk tube to the external nozzle. Accordingly, the nozzle adapter is attached to a tapered nozzle of caulking tube or gun, and enables the user to select various taper dimensions or angles of external nozzles by engaging the external nozzle with the nozzle adapter which is attached to the caulking tube nozzle. ## Claims ### Claim 1 A nozzle adapter comprising: a shoulder portion having a hole into which a tapered nozzle is inserted; a header portion protruded on the shoulder portion, having an end hole and configured to engage with an external object; and a clutch plate provided under the shoulder portion and configured to engage with the tapered nozzle and fix the hole of the shoulder portion at the tapered nozzle, wherein the clutch plate is attached to the shoulder portion via a plurality of pins and a plurality of pin holes, wherein the header portion, the shoulder portion and the clutch plate form an internal passageway through which the tapered nozzle is inserted and a material flows from the tapered nozzle to the external object. ### Claim 2 (depends on 1) The nozzle adapter of claim 1, wherein the nozzle adapter further comprises a neck portion provided between the shoulder portion and the header portion. ### Claim 3 (depends on 1) The nozzle adapter of claim 1, wherein the clutch plate is detachable from the shoulder portion. ### Claim 4 (depends on 1) The nozzle adapter of claim 1, wherein the clutch plate is fixed at the tapered nozzle and detachable from the shoulder portion. ### Claim 5 (depends on 1) The nozzle adapter of claim 1, wherein the clutch plate has a plurality of equidistant slots to fix the hole of the shoulder portion at the tapered nozzle. ### Claim 6 (depends on 1) The nozzle adapter of claim 1, wherein the clutch plate has at least four equidistant slots to fix the hole of the shoulder portion at the tapered nozzle. ### Claim 7 (depends on 1) The nozzle adapter of claim 1, wherein the clutch plate has a plurality of equidistant slots that are made of polypropylene as membranes to fix the hole of the shoulder portion at the tapered nozzle. ### Claim 8 (depends on 1) The nozzle adapter of claim 1, wherein the header portion has a screw thread for the engagement with the external object. ### Claim 9 (depends on 1) The nozzle adapter of claim 1, wherein the header portion has a bayonet fit for the engagement with the external object. ### Claim 10 (depends on 1) The nozzle adapter of claim 1, wherein the header portion has a clip fit for the engagement with the external object. ### Claim 11 (depends on 1) The nozzle adapter of claim 1, wherein the internal passageway has at least one of a plurality of tapered sections which allows the tapered nozzle to be adjusted in the internal passageway without a gap. ### Claim 12 (depends on 1) The nozzle adapter of claim 1, wherein the tapered nozzle is a caulk tube nozzle. ### Claim 13 (depends on 1) The nozzle adapter of claim 1, wherein the external object is an external nozzle. ### Claim 14 A nozzle adapter comprising: a shoulder portion having a hole into which a tapered nozzle is inserted; a header portion protruded on the shoulder portion, having an end hole and configured to engage with an external object; and a clutch plate provided under the shoulder portion and configured to engage with the tapered nozzle and fix the hole of the shoulder portion at the tapered nozzle, wherein the clutch plate has a plurality of equidistant slots to fix the hole of the shoulder portion at the tapered nozzle, and wherein the header portion, the shoulder portion and the clutch plate form an internal passageway through which the tapered nozzle is inserted, and a material flows from the tapered nozzle to the external object. ### Claim 15 A nozzle adapter comprising: a shoulder portion having a hole into which a tapered nozzle is inserted; a header portion protruded on the shoulder portion, having an end hole and configured to engage with an external object; and a clutch plate provided under the shoulder portion and configured to engage with the tapered nozzle and fix the hole of the shoulder portion at the tapered nozzle, wherein the clutch plate has a plurality of equidistant slots that are made of polypropylene as membranes to fix the hole of the shoulder portion at the tapered nozzle, and wherein the header portion, the shoulder portion and the clutch plate form an internal passageway through which the tapered nozzle is inserted, and a material flows from the tapered nozzle to the external object.
