My invention relates to dispensing tubes for use in dispensin shaving cream,-tooth paste,'cosmeties and t e like.
A purpose of my invention is to use palr impregnated with a suitable waterproo g filler such as bakelite lacquer, rubber, paraflin or oil for the bod portion of a dispensing tube. Optionally l may use any other suit able fibrous material than paper, for example fabric.
A further urpose is to mold a dispensing terminal of bakelite or optionally of other suitable molding material around both the inside and the outside of the inwardly 16 crimped end of a paper dispensing tube, and to use the progressvely greater thickness of the paper toward the end of the paper due to crimping it inwardly to progressively smaller diameter for making an interlocking bond W between the crimped end of the paper and the enfolding molding material.
' Further purposes will appear in the specification and in the claims.
I have electedy to show one only of the different forms of my invention, 'selecting va form that vis practical and eflicient in operation and which well illustrates the principles i involved.
Figure 1 is a longitudinal elevation' of a '0 finished dispensing tube embodying my invention.
-Figure 2 is a longitudinal section of Figure 1 taken in the plane of the paper .and showing in dot-and-dash the tubeof Figure 1 supplied with a usual cap and a usual foldf ed crimped closure at the filling end. 4
Figure' 3 is-a longitudinal section of a paper tube for use in manufacturing the Vbody portion of my dispensing tube. u f
Figure 4; is a long'tudinal section generally, similar to Figure 3 but showing the dispensing end of the tube crimped inwardly preparatory to molding.
Figure 5 is a top plan-of Figure 4.
i Figures 6 and 7 are sectional elevations through a conventional molding machine and illustrate diflerent steps of the molding of a dispensing terminal on to the crimped 60 end of the tube shown in Figure 4.
vprises a tubular4 body .10 and a terminal 11 Like numerals refer to hke parts ln all figures.
D escribing in illustration and not in limitation and referring to the drawings:
In the ast it has been oustomary to manufacture s ensing tubes by extrusion molding, the bo y portion of the tube and its dispensing terminal 'being a single integral member molded 'under great pressure, during which the metal forming the body portion of the dispensing tube and usually tin, flows up around a moving die or mandrel that is forcing its way into the tin 'or other metal molding material within a stationary portion of the mold. f
One of the purposes of my invention is to use a less costly material for the manufacture of dispensing tubes that will be equally well adapted to meet the needs of service.
I have discovered that a body portion of paper impregnated with a waterproofing filler such as oil, bakelite lac'quer, paraflin or rubber meets well the conditions of servic andthat the end 'terminal of the dispensing tubemay be molded upon the inwardly bent end of a tubular paper .body 'so as to. give a dispensing tube that is at-once very satisfac; torv in use and inexpensive to manufacture.
The finished dispensing-tube proper comthat has hitherto been made integral -with the body.A j A capv 12,'1of any desired and suitable type, is 'shown in dot-and-dash Figure 2, and will usually be supplied with the dispensing tube but does -not have direct relevance to the present invention. i
A closure 13, also shown dot-and-dash in Figure 2, is made by thecustomer after the tube has been fiued and also has-no.. direct, relevance to the present inventiomj L I show in Figurean ordinary'fpaper tube' v 14 whichhas been suitablyimpregnated with' waterproofing Vmaterial as 'already described. The 'first step in manufacturing my new tube is to inwardly crimp-the dispensing end of the tube shown in Figure 3. This crimpingmay be eifected in any'suitable wayiand gives an end'portion 15 that converges inin Figure 4.
wardly toward the tube axis as illustrated the small inner circle igure 5 at 17 being exactly the same as that aroun portion of the tube at 16. I
I mount the tube 14 on a metal die nrember 18, Figure 6, and lace a suitable quantity of molding materia 19 in a stationary mold 20 below and properly alined with the movable die member.
The movable member is forced downunder high pressure into the molding material at a temperature appropriate to the material used. I thus cause the molding material to enfold the crimped end of the paper tube. The molding material and the crimped end portion of the'tube fill all of the s ace between the mating members of the mo d when the movable member has been forced down into its lower-most position. In normal opcration, using a lump of molding material in the bottom of the fixed die the material will flow about and thoroughly face or cover both sides of the crimped end. Bakelite is a very excellent material for myv purpose but any other material is suitable.
To avoid any material tendency for the extrusion molding to force the end portion of the tube outwardl ahead of the flowing molding material may mount a portion of the molding material in the form of an annulus 21 yplaced inside the crimped end of the tube and about post 22, the remainder lying between the crimped end and the stationary mold. I prefer to crimp the dispensing end of the tube at before placing it on the movthe outside able die but optionally may crimp and mold with the same stroke of the die.
The illustration of the molding members is intended to be a conventional one for any suitable molding mechanism. As illustrated,
the stationary member is provided with a' threaded portion at 23 to form the threaded end of the terminal. A base member 24 is -spring-pressed at 25 into position to receive the end of thedownwardly moving central post 22 of the die member. This supporting member is kept 'from moving upwardly by a suitable collar 26 and is slidably mounted in a plate 27 fastened rigidly to the bottom o the stationary mold. When the lower end 22 of 'the movable member engages-the upwardly pressing member 24 Ithe latter member yields downwardly sufficiently to permit the full down stroke of the moving die member. This yielding prevents evident, that the inward crimplportion impervious to t 4comprising a pa the pressure againstthe lower end of the movin'ikpember from becoming unduly high.
e die member on its u stroke moves out of the tube 14 which is left y imbedded in the molded terminal.
. -The lower and stationa molding-member may or may not be divide for more -easy reinoval of the threaded terminal from its molded seat. Usually this member will be m ade in one piece in which event 'the tube will be spun out of the thread at 23.
The upwardly directed and outwardly flaring portion 28; of the lower mold member will usually-be given a suitable lettering or other marking in accord with the desires of the customer. I
The dispensing tubes are rovided with suitable caps 12 of Figure 2 an sold with the charging end 13 o en.
The customer ls the tube at the open end and -subse uently crimps the o n end together -as i lustrated in dot-andash in Figure 2, in the usual way. This, however, forms no part of the present invention which is directed at a two-part dispensing tube having a body portion made up of paper' or other suitable 'fibrous material impregnated .with
suitable waterproofing material and a molded dispensing terminal enfoldin the inwardly crimped end lof the'tubular bo y rtion.
In view of my invention an disclosure Variations and modifications to meet individual whim or particular need will doubtless become evident to othersl skilled in'v the art,-to obtain all or part of the benefits of my invention without copying. the structure shown, and I, therefore, claim all such in so far as they fall within the reasonable spirit and scope of my invention.
Having thus described my invention, what I claim as new and desire to Patent-is:
1. A two-part collapsible dispensingf tube compaising alfibrous body portion and a dispensing terminal molded to one end thereof. 2. A two-part collapile dispensing tube comprising a fibrous y: portion, an impregnating filler within the interstices of the material of the body ortion to make said I lie tube contents, and a dispensing terminal molded toone end of the body portion. i
3. A two-part collapsible dispensing tube r body portion and a dispensing termina molded to one end thereof. 4. A two-part collasible dispensing tube comprising a pa r bo y portion, an impregnating filler wit in the interstices of thel material of the body portion to make said portion im rvious to the tube contents, and a diepensing terminal molded to one end of the bo y portion.
5. A collapsible dispens' tube oomprising va body ortion of rous material crimped inwa ly at one end, and a molded secure by Letters igo 'lll
