Title: Tube/injector for adhesive glues
IPC: B65D/
Filed: 1989-11-17
Abstract: The principal object of the invention is to provide a tube/injector for adhesive glue which can be handled easily and then retained. A further aim of this invention is to provide a tube/ injector for adhesive glue which does not soil the hands and fingers with glue when in use or when it is retained after having been used. A further aim of this invention is to provide a tube/ injector for adhesive glue which can discharge the glue while the tube is held in its case. A yet further aim is to provide a tube/injector for adhesive glue, of the pipette type, which can discharge only the desirable amount of adhesive glue without the liquid being touched. Yet a further aim of this invention is to provide a tube/ injector whose adhesive glue can be discharged without the tube having to be touched, it being possible for this purpose to press only the protection springs existing to the left and to the right. A further object of the invention is to provide an adhesive tube/injector which allows the excess of adhesive glue discharged to be sucked back again into the tube, it being necessary for this purpose to release the protection claws on the left and on the right. In order to achieve the above objects, this device includes a tube/injector for adhesive glue A which comprises an elastified container 11 filled with an adhesive liquid, with claws for pressure located on the sides 13 14 linked to one another by a spring coupling 17 18 which keeps them separate 13 14 from one another, a case 12 for retaining the tube A as well as a cannula syringe 11d for the aforesaid tube A which projects from the upper part via the operation openings 12K 12m forming the peripheral wall, the claws for pressure 13 14 linked to one another and separated being placed so as to project and to retract to the respective openings 12K 12m, a removable sealed lid 15 placed in the final part of the case 12 in order to be able to hold the bottom of the aforesaid tube for adhesive liquid, a screw cap placed on the bottom of the case in order to secure the tube of adhesive liquid and a removable upper lid 16 placed on the case 12 for closing the syringe cannula 11d of the tube 11 and an upper part of said case. Provision may be made for the adhesive liquid to emerge drop by drop on the location to be glued without the location itself having to be touched. What is supplied is a tube/injector for adhesive glue A which comprises an elastified container 11 filled with an adhesive liquid, with claws for pressure located on the sides 13 14 linked to one another by a spring coupling 17 18 which keeps them separate 13 14 from one another, a case 12 for retaining the tube A as well as a cannula syringe 11d for the aforesaid tube A which projects from the upper part via the operation openings 12K 12m forming the peripheral wall, the claws for pressure 13 14 linked to one another and separated being placed so as to project and to retract to the respective openings 12K 12, a removable sealed lid 15 placed in the final part of the case 12 in order to be able to hold the bottom of the aforesaid tube for adhesive liquid, a screw cap placed on the bottom of the case in order to secure the tube of adhesive liquid and a removable upper lid 16 placed on the case 12 for closing the syringe cannula 11d of the tube 11 and an upper part of said case. Provision may be made for the adhesive liquid to emerge drop by drop on the location to be glued without the location itself having to be touched.
