COLLAPSIBLE TUBE CLOSURE AND METHOD FOR MAKING THE SAME Filed Jan. 19, 1957 Patented Sept. 13, 1938 PATENT OFFIQE COLLAPSIBLE TUBE CLOSURE AND METHOD FOR MAKING THE SAME James Hansen, Flushing, N. Y., assignor of onehalf to Gustav Drews, Brooklyn, N. Y.
Application January 19, 1937, Serial No. 121,255
18 Claims.
' This invention relates to discharge control valves, particularly to collapsible tube closures and to the method of making the same.
Among the objects of the present invention, it is aimed to provide an improved collapsible tube closure and a method for making the same, which closure has a spiral valve seat and thread corresponding in pitch to one another as shown in my copending application, Serial No. 68,855 filed March 14, 1936 and which closure comprises a neck having an internal thread forming flange and an inclined spiral seat on the edge of the neck, and a cap having an external thread to cooperate with said internal thread and a spiral face to ride on said spiral seat.
The method of forming this closure consists essentially in providing an'internal thread forming flange on the neck ofthe tube and a valve seat on the edge of the neck, and a spiral face on the cap with an internal axially extending flange to clear the thread forming flange of the neck when assembling and moldable'to be bent around the thread forming flange of said neck by an expanding tool or the like preferably introduced through the inside of the tube.
These and other features, capabilities and advantages of the present invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which Figure 1 is an elevation of the upper part of a tube equipped with the present improved closure in closed position;
Fig. 2 is an elevation of the tube equipped with the present improved closure in dispensing position;
Fig. 3 is an enlarged fragmental section detached of the closure parts before initial assembling;
Fig. 4 is an enlarged fragmental section of the closure parts after final assembling;
, Fig. 5 is an enlarged section on the line 5-5 of Fig.4;
i Fig. 6 is an enlarged fragmental section on the line 6-6 of Fig. 2; v
Fig. '7 is an enlarged section on the line 1-1 of Fig. 6;
Fig. 8 is an enlarged perspective of the cap before initial assembling;
Fig. 9 is an enlarged perspective of the washer or yieldable seat detached; and
Fig. 10 is an enlarged fragmental perspective of the tube before assembling.
In the embodiment shown, there is illustrated a tube body I having a diminished neck 2 at one end and a clinched plate 3 closing the other or lower end of the body I. The neck], see particularly Figs. 3, 6 and 7, has a spiral seat 4 slightly inclined downwardly toward the center of the body I and extending inwardly'to form a shoulder 5 beyond the inner periphery 6 of the neck 2.
This extended seat portion also extends from the highest point of the spiral seat to the lowest point, see the extendedportion I which performs an important function in anchoring the cap to the neck. The spiral seat 4 preferably consists of a single convolution in which the ends of the convolution are connected by the aforesaid extended portion 1.
The cap 9 has a cylindrical outer contour and a finger engaging flange ortab Ill preferably extending diametrically across the outer upper face. The cap 8 when initially mounted or shaped, see Figs. 3 and 8, preferably has a spiral face II and preferably formed in a single convolution with the ends thereof connected by the inclined face I2. The faces II and I2 preferably have a continuous outer flange I3 of uniform height throughout and an inner flange I4 substantially equal in height to the height of the flange I3 at the portion I5 extending from the uppermost point of the spiral face I I for a distance of about one-fourth of the length of the face II and the remaining portion I6 of the flange I4 being at least twice the height of the portion I5 for the purposes hereinafter to be described.
Shaped to conform to the faces II and I2, there is provided the washer I1 constituting a seal between the cap 9 and neck 2. This washer Il may be composed of any suitable yieldable material suchas cork, a cork compound or the like.
It will here be noted that when the seal I'I is squeezed into place, it will be anchored between the flanges I3 and I4 and extend, along the inclined face I2 to the extreme inner edge of the cap wall where the inner flange is interrupted. After the sea] I! has been secured in place then the cap 9 with its flange portion I6 still extending axially is passed into the neck 2, before the tube is filled and while the lower end is still open. It will then only be necessary, preferably after the cap 9 has been turned to the closed position shown in Fig. 1, to bend the flange portion I6- outwardly against the shoulder 5 when a thread will be formed parallel to the spiral seat 4. The bending of the flange portion I6 may be effected by any suitable tool, such as an expansion tool or the like inserted through the lower open end of the body I.
' When the portion I6 is so bent outwardly, see particularly Fig. 6, the outwardly bent edge of the portion I6 will cooperate with the extended portion 1 to form a limiting stop for the rotation of the cap into open position, that shown in Fig. 2 and in turn to serve as an anchoring means permanently to anchor the cap 9 to the neck 2. Thereupon, after making sure that the cap 9 has been turned into closed position, the body I while inverted may be filled and then a substantially smooth cylindrical surface will be presented with the cap and neck portions, in the interest of the appearance of the'article and in,
the interest of facilitating the cleaning of the neck and cap after use.
It is obvious that various changes and modiflcations may be made to the details of construction and in the steps of the method without departing from the general spirit of the invention as set forth in the appended claims.
