UNITED STATE s PATENT osi-lcs yaovaszs COLLAPSIBLE TUBE CLOSURE Philip Heinsberg. Chicago., lll. Y

Application `December' 11, 1936. SerialNo. 115.296

11 Claims. r(Cl. 221-60) when screwed into connected relation with thel nipple to close or seal the latter and thus prevent extrusion of the paste within the tube; and (2) la continuous skirt which surrounds the cap part and serves not only as a finger grip whereby the cap part may be readily un- 15 screwed from. or applied to the discharge nipple of the tube but also as a pedestalv whereby the tube may be retained or supported in an invertedI upstanding position.

lOne object of the invention is to provide a collapsible tube closure of this type which is more practical and durable, and is less costly to produce than previously designed closures of the same general character by reason of the fact that the pedestal forming skirt is formed separately from the cap lpart and is in the form of a sheet metal stamping. s

Another object of the invention-is to provide `a collapsible tube closure of the last mentioned character in whichl the separately formed skirt embodies a depending inturned ange in the central portion thereof and the cap part is knurled onthe outer face thereof and is pressed t into interlocked or fixed relation wi/th the inrolled flange of the skirt. ln is to provide a closure of the type and c e racter under consideration in which the separately formed sheet metal skirt is oficonical design, that is, tapered from the lower end thereof to the upper 40 end and embodies a rib type formation around the central portion thereof whereby it is reinforced against -bending or distortion.

A still further object of the invention is to vprovide a collapsible tube closure which is gen- -erally of new and improved'construction and ciilciently serves its intended purpose. f

Other objects of the `invention and the various advantages and characteristics of the present collapsible tube closure will be. apparent from a consideration of the following detailed descripv.

tion.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conelusione hereof. v

' or close ythe latter.

In the drawing which accompanies and forms a part of this specification or disclosure and in whichlike numerals of reference denote corresponding parts throughout the severalviewsf Figure 1 is a side. .elevational view showing 5 a closure embodying the invention in connected relation with the discharge nipple of a paste dispensing collapsible tube:

Figure 2 is a vertical sectional view of the closure, illustratingthe construction and design 10 of the skirt and cap part and showing the man ner in which the cap part is fixed to the inturned flange of the skirt;

Figure 3 is an inverted plan view of the closure, parts being shown in horizontal section for purl5 poses of illustration:

t Figure 4 `is a vertical section of the skirt of the closure; and 1 e Figure 5 is a side; elevational view of the cap part 2o The closure which is shown in the drawing constitutes the preferred 'embodiment of the invention. It comprises a cap part 6 and a skirt 1. and is designed'to form a seal as well as a pedestal for a collapsible paste dispensing tube 25 T. The latter is shown in the drawing as being of conventional design or construction and consists of a. continuous side wall t and an end wall t1. The end wall embodies in the central portion thereof an externally threaded discharge 30 nipple t2 through which the paste within the tube may be discharged or' extruded when the side wall is squeezed or pressed together.

The cap part 6 of the closure is formed of tin or like'metal. It serves as a seal for the dis- 35 charge nipple of the tube and consists of a circular end (wall 8 and a cylindrical side wall 9. The side wall forms with the end wall 6 s. socket for the discharge nipple and embodies an internal screw thread IB for the external thread of the 40 nipple. The end wall 8 is formed integrally with the side wall il .and is adapted to extend across the end of the discharge nipple when the cap part 6 is in connected or sealed relation with the nipple. .A sealing disk ll of cork or like -elastic material is disposed in the socket within the cap part of the closure and abuts or is seated against the inner face of the end wall 8. When the cap part -6 is screwed tightly into connectedv 59 relation with the discharge nipple of the tube this disk is clamped by the end wall 8 against the outer end of the nipple and serves to seal The side wall of the 'cap part i is of uniform diameter from end to end and 55 has longitudinal knurls I2 on its outer face or periphery.

The skirt 'I of the closure surrounds the cap part 6 and serves as a handle or finger gripping medium for facilitating unscrewing and applica.- tion of the cap part and also as a pedestal whereby the tube T may be retained or held in an upstanding position. It is in the form of a sheet metal stamping and is conical. that is. tapered from the bottom thereof to its top. The upper or small end of the skirt embodies an integral inturned flange i3. This flange fits tightly around the upper end of the cylindrical side wall I of the cap part 6 and forms the attaching or connecting medium between the cap part and theskirt. In assembling the closure, the cap part is inserted into the flange and is then pressed inwards until the outer end of the side wall I is flush with the small or upper end-of the skirt l. During the pressing operation the knurls i2 on the outer face or periphery of the side wall of the cap part are jammed into lnteriitting relation with theinner A periphery of the flange and are distorted in such manner that the cap part becomes rigidly attached or fixed to the flange I3. As shown in Figure 2, the angegil is but slightly more than half as long as the side wall of the cappart. Be

cause of this and the fact that the outer and of the side wall of the cap part is flush with the small end ofthe skirt 'I the inner end of the side wall of the cap part is exposed and hence may be gripped for turning purposes when the fingers are' inserted within theskirt 1. The lower or large end of the skirt l projects beneath the cap part 6. as shown in Figure 2,'and the bottom extremity thereof is bent upwardly and then inwardly to form an annular bead Il. 'I'his bead serves to reinforce or strengthen the skirt and operates as a foot for the skirt when the closure is placed on a shelf or other supporting surface. The cen-- ly small. In addition eillcient interlock or rigid connection betweenthe side wall ofthe cap part 6 and the flange il is effected. The latter is directly attributable to the fact .that the knurls I2 which are formed on the outer periphery ofV the side wall of the rib part are softer than the ange and as a result grip the latter lwithout weakening it to any material extent.

When it is desired to apply the closure to the tube Tit is only necessary to insert the outer end of the extemally threaded discharge nipple tl in the socket in the cap part t of the closure and then screw the cap part on the nipple by rotating the skirt 1. When the closure is applied to the tube T the latter may, if desired. be placed in an upstanding position. When the tube is placed in such a position the skirt l serves as aand retains the tube in place. By reason ofthe factthattheskirtlisconicalascontradlstimguished from cylindrical the outenmarginal-portion of the end F1 wall of the'tube-T isexposed and hence any paste which accumulates thereon `maybereadilyrelnovedwhiletheclosureisin place.

The hereinl described collapsible tube closure due to its specific construction may be manufactuxedatalowandreasonableeost. Itiapraetical and durable and elciently fullls its intended purpose.

The invention is` not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims. without departing from the spirit and scope of the invention.
