COLLAPSIBLE TUBE.
Specification of Letters Patent.
Patented Feb. l5, 1921.
Application filed May 10, 19.18. Serial No. 233,609.
To all whom 'it-,may conc-era Be it known that I, CHARLES WEBER, a citizen of the United States, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Collapsible Tubes, of which the following is a specification.
My invention relates to improvements in collapsible tubes adapted to contain liquid, paste, powder or the like, and my invention pertains particularly to improved means for permanently and securely closing the usual charging end of the tube, that is to say, the end opposite the outlet or nozzle through which the contents are to be discharged.
In carrying out my invention I fold the end portion of the tube to be closed to provide a hook-like projection, and l provide a clip having a main body or back portion and two longitudinal folds that provide an inner member and an outer member, the inner member being spaced from said back portion and said outer member being spaced from the inner member. lVhen the clip is on the tube the folded hook-like projection A of the tube will be received between said back portion and4 said inner member ofthe clip, and the side portion of the tube end will be received between the two members of the clip in such position that the edge of the inner member enters the bight of the hooklike folded projection of the tube. When' the parts are thus assembled, the clip may be compressed to squeeze and grip the adjacent portion of the tube with the result that the clip and tube will remain securely attached together and pulling of the clip from the tube will be prevented. The clip may be made of suitable stiff metal so as to retainv its folded compressed form on the tube.
The clip is so organized that it may be slid in the direction of its length upon the folded end portion of the tube so that the hookdike projection of the tube may slide between the fold and the back of the clip for properly positioning the clip on the tube, and then said parts may be pressed together as stated.
Reference is to be had to the accompanying drawings forming part hereof, wherein,
Figure 1f isa perspective view of a collapsible tube ready to receive my improved clip; Fig. 2 is a perspective view of said cllp; Fig. 3 is an enlarged fragmentary detail of a portion of Fig. l, showing assemblage of the tube land clip; Fig. is an enlarged side view illustrating a portion of the tube and clip attached thereto; Fig. 5 isan enlarged edgeview of the clip and Fig. 6 is an enlarged section on the line 6, 6, in Fig. el. v
Similar numerals of reference indicate corresponding parts in the several views.
In the accompanying drawings the numeral l indicates a collapsible tube of any suitable or well known construction, which is adapted to contain liquid, powder, paste and the like in an ordinary manner. The material of the tube includes pyroxylin or similar material and it is capable of being rolled or folded but its'surface is so smooth 'that an ordinary metal clip such as used on metal tubes can not secure a sufhciently' firm grip to be held in place by frictional engagement where pressure is applied tending to move it. The tube may be provided with any suitable outlet neck 2 and 'a removable cap 3. The opposite end of the tube may be open as customary for charging,.and after the tube is charged its opposite walls at the open en d are to be brought together, and said end portion is then folded at least once to form the'hook-like projection 4 eX- tending transversely along the main end portion 5 and spaced therefrom a slight distance, and extending in the direction of the tube. My improved clip is indicated generally at 6 and comprises a suitable piece of,
sheet metal, (preferably of relatively stiff metal) folded twice upon itself on one side providing the main or back portion 7, the
.inner member-8 spaced therefrom and eX- j ytending from one edge of the back and the folded member 8 of the clip is adapted to fit in the bight 4* of the folded end of the folded end of the tube in such a manner that the portion 4 of the tube will enter space l0 and the portion 5 of the tube will enter the space 11 of the clip, and then when the clip has-been brought to desired position relatively to the width of the tube the clip may be squeezed or compressed firmly against the material of the tube, so that the hooklike projection 4L will be compressed between vthe member 8 and back 7 of the clip and the part 5 of the tube will be compressed between members 8, 9, of the clip. By the means described an air-tight and leak-proof closure is made at the end of the tube, and the clip will not be pulled off the tube in use because of the interlocking of the member 8 of the clip in the bight la of the tube, and the squeezing or compressing together of the parts, since the clip will not unroll because of its flatwise compressed condition along the folded edges thereof.
While my improved clip may be used upon collapsible tubes made of metal, of any well known variety in common use for such purpose, my invent-ion is particularly applicable to tubes made of or comprising non-ductile material, such as pyroxylin, of suflicient thinness to be folded and rolled, which tube when folded and provided with a bight, as at ta, tends to remain in a set and folded condition, the material of the tube having a certain amount of stiffness as compared to the ductility of collapsible tubes of lead or alloy metal.
My improvedform of clip is cheap to manufacture, since the clips can be made readily by machinery and the assemblage of the clips and tubes together is inexpensive. My improved form of clip is particularly adapted to tubes charged with liquid, since the folded end of the tube has the advantage of serving to prevent the escape of the liquid while the clip is being applied to the tube, as distinguished from the known man* nerV of applying a flat strip to the open end of a tube and then rolling the end of the tube and strip together while the liquid is in the tube.
j Having now described my invention what l claim is:
l. A collapsible tube having a fold at its end providing a projection extending transversely 'and back along the tube, and a clip upon the tube having a flat back and a flat inner and a flat outer member extending from the back, the projection of the tube being between the back of the clip and its inner member, and the adjacent body portion of the tube being between the said members of the clip, the edge of the inner member of the clipjopposing the bight of the fold of the tube being smooth, said clip being compressed upon the adjacent portions ofthe tube.
2. A collapsible tube comprising nonductile flexible material having a flat transverse fold at it-s end providing a projection extending back parallel to the flat portion of the tube and spaced therefrom, and a clip upon the tube having a flat back provided With members forming integral continuations thereof at opposite ends spaced therefrom and from each other in parallel relation on one side of the back and extending in opposite directions, said projection from the tube being located between the back and one of said members and the edge of said member atl the bight of the fold being smooth and the adjacent body portion of the tube being between said members, said clip being compressed upon the adjacent portions of the tube to form a liquid tight 'oint.
Signed at New York city, in the county of New York and State of New York, this 3rd day of May, A. D. 1918.
CHARLES WEBER.
