ATTORNEY March 31, 1970 R. P. SETERA I TUBE FOR TOOTHPASTE 0R SIMILAR MATERIAL Filed May 16, 1968 United States Patent O 3,503,544 TUBE FOR TOOTHPASTE R SIMILAR MATERIAL Roger Paul Setera, San Francisco, Calif. (2704 NE. 27th, Portland, Oreg. 97212) Filed May 16, 1968, Ser. No. 729,698 Int. Cl. B65d 47/00 US. Cl. 222--556 1 Claim ABSTRACT OF THE DISCLOSURE A toothpaste or other tube is formed with a head at the upper end provided with a flat groove into which fits a hinged cover having a plug which enters the neck of the tube when the cover is closed, the lid having a projecting free end whereby it may be flipped open with the thumb of the hand holding the tube, thus permitting the tube to be opened and used with one hand.
BACKGROUND OF THE INVENTION The invention relates to closures for tubes containing toothpaste, shaving cream, or any other material adapted to be extruded from the tube upon the exertion of pressure thereon. These tubes ordinarily are provided with screw caps which requires that the tube be held in one hand and the cap removed with the other, and replaced in the same manner. The caps are easily dropped on the floor or lost.
There have been developed various types of tubes of this character having covers, usually hinged, or connected to the edge of the tubes by flexible plastic elements so that the tubes may be opened with one hand. Such tubes, however, are usually relatively expensive to manufacture and very often awkward in use, it the user attempts to open the tube with one hand.
SUMMARY OF THE INVENTION With the present invention the tube is provided with a preferably integral head having a top surface which is flat and substantially perpendicular to the axis of the tube. This surface is provided with a straight relatively wide flat groove adapted to receive a flat cover hinged at one end to the head of the tube and having its free end projecting beyond the head to be readily accessible so that the user may hold the tube in one hand and flip the cover to open position with this thumb.
The cover is provided with a tapered plug adapted to enter the outlet opening of the tube when the cover is closed. The entire cover is made of plastic, having an appreciable degree of flexibility and this fact is utilized in forming the hinge means for the cover. The cover is provided with a transverse rib the ends of which have small projecting trunnions adapted to enter openings in .the head of the tube to hingedly connect the cover to the head. A recess is formed in the head of the tube at the hinge end of the cover to provide space for the hinge rib, and the recess is somewhat wider than the width of the cover to facilitate the entrance of the hinge trunnions into their openings.
The top surface of the cover is flat throughout its area so that when the cover is closed, the tube may be inverted and the surface of the cover placed on a flat surface whereby the tube will remain in standing position without support. To increase the stability of the tube when so standing, the top surface of the head is flat and lies in the plane of the top surface of the cover so that the tube will remain standing in inverted position with a substantial degree of stability.
3,503,544 Patented Mar. 31, 1970 BRIEF DESCRIPTION OF THE DRAWINGS DESCRIPTION OF THE PREFERRED EMBODIMENT A conventional tube 10 for toothpaste, shaving cream or other material, is formed in a conventional manner except that it is provided at the upper end with an integral head 12, one side 14 of which extends substantially to the extremity of the tube 10 while the other side 16 is offset inwardly from the adjacent side of the tube. The head 12 is provided with a flat upper surface 18 substantially perpendicular to the axis of the tube and provided with a relatively flat groove 20 having parallel side edges as shown in FIGURE 3.
A cover indicated as a whole by the numeral 22 is provided for the tube. This cover is formed flat throughout except as noted below and is of the same depth as the groove 20 to lie therein when the cover is closed as shown in FIGURES 1 and 4. Opposite edges 24 of the cover are parallel and lie adjacent to edges of the groove 20. It will be noted that top surfaces of the cover and the head 12 lie in a common plane as shown in FIGURE 4.
The cover 22 is formed of plastic, having an appreciable degree of flexibility for a reason which will become apparent, and the cover is provided on its underside with a tapered integral plug 26 adapted to lie within the opening 28 in the head 12 through which material in the tube is extruded when the cover is opened.
One end of the cover 22 is provided at its underside with an integral transverse rib 28, the main body of which terminates in the planes of the edges 24 of the cover. Each end of the rib 28 is provided with a small relatively short trunnion 30 adapted to form hinge pins for the cover. At such end of the cover 22, the head 12 is provided with a recess 32 to allow space for the rib 28. The side edges of the recess 32 are spaced from the edges of the cover as at 34 for a purpose to be described. The opposite end 36 of the cover projects substantially beyond the setback portion 16 of the head 12 as clearly shown in FIGURE 1.
OPERATION The trunnions 30 are sufliciently small in diameter as to render them somewhat flexible. In assembling the device, the cover 22 will be arranged in a vertical plane and tilted laterally of the head so that one of the trunnoins 30 may be inserted in the associated opening 38. The cover is then pushed in the direction of such opening until the edge of the cover engages the adjacent side edge 34 of the recess 32. The other trunnion 30 then may be pushed downwardly and will flex over the edge 34 to snap into the associated opening 38. The cover then may be slid slightly in the direction of the trunnion last inserted in its opening to center it relative to the recess 32.
The cover will hinge about the trunnions 30 to move to the closed position shown in FIGURES 1 and 4, the edges of the groove 20 maintain the cover properly centered. When it is desired to open the tube, the user may hold the tube in one hand and use his thumb against the projecting end 36 of the cover and flip the cover to the open position shown in FIGURE 2. Paste or cream then may be extruded through the opening 28, whereupon the cover will be closed as shown in FIGURE 4 with the plug 26 arranged in the opening 28. The tapering of the plug 26 permits the hinging of the cover about the common axis of the trunnions 30 with no dragging of the plug against the side of the opening 28.
As previously stated, the cover is of substantial area and with the cover closed, the tube may be inverted to stand on end, with the surface of the cover resting on a fiat supporting surface. To increase the stability of the tube when so standing on end, the top surface of the head 12 is flush with the top surface of the cover as shown in FIGURE 4. Thus the tube will have substantial stability when standing on end, as stated.
The tube and head are cast in the usual manner. The cover as a whole being formed of plastic may be very cheaply made and cheaply installed without the added expense of separate metallic hinge pins and without the use of flexible connecting flaps between the cover and tube, which are subject to breakage after repeated bending.
From the foregoing it will nOW be seen that there is herein provided an improved tube for toothpaste or similar material which accomplishes all of the objects of this invention and others, including many advantages of great practical utility and commercial importance.
1. A toothpaste tube or the like comprising a tubular body and a head, said head having an extrusion opening therein, said head being provided in the upper surface thereof with a wide shallow groove having substantially parallel sides, a fiat plastic cover approximately the width and depth of said groove and adapted to lis therewithin when the cover is closed, said cover being provided at the opposite edges of one end with oppositely projecting trunnions possessing an inherent degree of flexibility, the adjacent end of said head having a recess therein wider than said groove, the edges of said recess being provided with openings hingedly to receive said trunnions, the end of said cover opposite said trunnions projecting substantially beyond said head to form a finger piece for opening said cover, said cover being of substantial area and having a fiat upper surface perpendicular to the axis of the tube, and said head having a fiat upper surface flush with the surface of said cover to support the tube in vertical position when inverted and placed upon a flat supporting surface, said cover having an inverted frusto-conical hollow compressible plug on its under side adapted to enter the opening in said head and when said cover is closed, and to be held therein by friction when the tube is closed.
