Description
April 7, 1936. J. P. BRUNETTI PASTE TUBE CAP Filed June 10, 1955 [no [or Patented Apr. 7, 1936 UNITED STATES PATENT OFFICE PASTE TUBE CAP Joseph P. Brunetti, Clarksburg, W. Va.
Application June 10, 1935, Serial No. 25,896
1 Claim. (Cl. 221-60) This invention relates to a paste tube cap, the general object of the invention being to provide a cap formed of rubber or the like having a slit cut in its top whereby pressure of the contents of the tube, when the tube is pressed upon, will force some of the contents through the slit and when the pressure is released the walls of the slit will go together to prevent the entrance of air and foreign matter into the tube.
This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-
Figure 1 is a fragmentary elevation showing one form of cap applied to a tube.
Figure 2 is a section on the line 2-2 of Figure 1.
Figure 3 is a section on the line 3-4 of Figure 2.
Figure 4 is a view showing the cap in section as being threaded to the tube.
Figure 5 is a section on the line I5 of Figure 3, the section taken through the cap alone.
In this drawing the numeral l indicates the cap which is formed of rubber or composition of rubber and this cap is preferably used with a tube 2 having a flange 3 at the top of its neck, the vflange fitting in an internal groove 4 in the cap as shown in Figure 2. However, if desired the cap can be formed with theinternal threads I and fitting the usual threads of the tube 2' as shown in Figures 4 and 5. The upper end of the cap is formed with a ridged tip I which is grooved as shown at i at its junction with the capandaslit Oisformedbyasharpknii'einthe top of the cap, the slit terminating upwardly slightly above the plane of the groove l.. Thus the tip I thoroughly seals the contents of the tube when the cap is placed thereon, and then when the customer wishes to use the contents it is simply necessary for him to take a sharp knife and cut the tip I at the groove 8 which will expose the slit 9. Then by squeezing the tube, pressure of the contents will force the walls of the slit apart so that the contents will pass through the same and as soon as pressure is released the walls of the slit will close and thus seal the contents of the tube against the air and foreign matter.
Figures 3, 4 and show the tip as having been cut oil.
If desired, the tip I can be omitted and the cap come without the slit so that the customer will make the slit himself or if desired the cap can be furnished with the slit and placed in the carton containing the tube with the regular cap and then the customer can remove the regular cap and substitute the rubber cap.
It is thought from the foregoing that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What is claimed is:--
A cap for a paste tube, comprising a body formed of rubber and of substantially domeshape and adapted to fit over the neck of a tube, said cap having a ridged tip at its upper end having its exterior wall separated from the exterior wall of the cap by an annular groove, the
top of the cap having an-elongated slit therein extending from the top wall of the interior of the cap to a point slightly above the plane of the groove, whereby by cutting the tip from the body on the line of the groove, the upper end of the slit will be exposed.
JOSEPH P. BRUNE'I'I'I.
