This invention retates to means for holding and extruding paste and liquid materials, and has for its main object to provide between a container for the material and a separate member having a self-closing extrusion aperture, a simple and uncostly connection which cannot easily be undone and discourages attempts to use the separate member on another container after disconnection from the first container. A further object is to provide a device for sealing the aperture until use of the means is commenced. A still further object is to provide a means of spreading the material as it is extruded.
According to my invention, means for holding and extruding paste and liquid materials and comprising a collapsible container in combination with a self closing extrusion aperture provided in a separate member, has the separate member permanently affixed to the exterior of the collapsible container by a device adapted to discourage or prevent ready detachment .of the said member from the container.
One device consists in clenching means provided externally on the collapsible container to clench the said member to the collapsible container.
The clenching means preferably consists of or comprises an annular flange or claws provided on the exterior of the collapsible container round a neck provided on the container.
The said member preferably is of rubber or the like resilient material and has a neck which is supported internally by an externally conical neck containing the outlet from the container.
The neck of the member may have an annular bead which assists in obstructing removal of the said member from the container.
I attain this object by the means illustrated in the accompanying drawings and hereinafter claimed.
In the accompanying drawings Figure 1 is a side view in vertical section of a member having a self-closing extrusion slit.
Figure 2 is a fragmentary side View, partly in section of the front end of a collapsible container.
Figure 3 is a side view in vertical section of the said member assembled on and secured to the said container.
Figure 4 is a plan view in section taken on a line corresponding with line 4-4 of Figure 3.
Figure 5 is a fragmentary side view, partly in section and illustrates another construction.
Figures 6 and 7 are fragmentary side views of the front ends of two containers and illustrate different modifications of details.
Figure 8 is a fragmentary side view in section of a part of a member having a self-closing extrusion slit and illustrates another construction.
Figure 9 is a fragmentary side elevation drawn at right angles to Figure 8.
Referring to the drawings, in the construction shown in Figures 1 to 4, I provide a collapsible tube I, Figure 2, of metal having at its front end, an integral annular shoulder 2 on which there is an integral neck 3 having an outlet hole 4 through it. The'neck 3 has an external surface 5 of marked conicity and having its largest external diameter where it joins the shoulder 2. Surrounding and concentric with the neck 3 there is an annular flange 6 formed integral with the shoulder and extending in axial direction, the flange 6 preferably being somewhat longer than the neck 3. The portion 1 of the inner surface of the flange 6 which is nearest the shoulder 2 is of marked conical form with the smallest diameter of the said portion nearest the shoulder 2. The remaining portion 8 of the said surface is cylindrical or slightly conica1 with the smallest diameter of the said remaining portion 8 nearest the portion 7. The external surface 9 of the flange 6 is also wholly or partly conical with the largest diameter nearest the shoulder 2.
I also provide a hollow nipple l8, Figures 1, 3 and 4 composed of rubber or the like resilient material and comprising a head and a neck Ill. The head has a domed front part ll springing from a conical part l2 which tapers inwards from the front part to join the neck in. The neck [0 projects rearwardly from the conical part l2.
. The domed part II has an extrusion cut l3 or slit in it. The interior surface M of the neck I0 is conical to fit on the exterior surface 5 of the tube neck 3. The neck I 0 has an annular external bead l5 or thickened portion at its rear end, the portion iii of the peripheral surface of the bead being conica1 to suit the conicity of the lower portion 1 of the inner surface of the flange 6. Measured from the front to the rear, the dimension of the bead l5 or thickened portion is less than the length of the flange. The remaining portion I! of the peripheral surface of the bead [5 or thickened portion is curved.
The nipple l8 and the tube I are assembled by pushing the nipple neck I0 into the annular space between the tube neck 3 and the flange 6, whereupon the relatively thin rim of the flange 6 is forced inwards or inwards and rear'wards, for example by spinning, to clench the nipple neck in against the tube neck 3 and the bead I5 tightly in the lower portion of the space I!) existing between the neck 3 and the flange 6. Figures 3 it is clenched. Preferably the length of the nipple neck it is substantially no greater than is necessary to allow the rim portion'of the flange 6 to be bent inwards into'its clenching position without damage to the nipple head.
The conical form of the surfaces 5, 7, l4 and I6 causes the rear portion of the nipple neck Into] be wedged on the tube neck 3 and between the neck 3 and the rear portion 1 of the flange by the rearward pressure exerted by the rim of the flange 6 when the said rim is bent into the clenching state.
The resulting connection between the nipple l8 and thetube i is liquid and paste tight and is neat. It discourages the idea of detaching the nipple l8 for use on some other collapsible tube. The internal shape of the nipple neck Hi unfits it for use on a tube not furnished with clenching means, because pressure exerted on the nipple by the contents of the collapsible tube when the tube is squeezed would be assisted by the conicity of the surface [4 to force the nipple off the neck of the tube.
When the collapsible tube is squeezed the consequent pressure on the paste or liquid, for example tooth paste, boot polish, adhesive and so forth, contained therein, is transferred by the paste or liquid to the interior of the nipple'head and acts outwardly thereon to force the sides or" the cut 13 or slit apart and permit a ribbon of liquid or paste to be extruded through it. When squeezing ceases, the elasticity of the material of which the said head is composed is sufficient to squeeze from between the sides of the cut I3 or slit, any remnant of the paste or liquid left in the cut or slit and press the sides sufficiently close together to prevent leakage of paste or liquid through the cut or slit.
Instead of the flange having a continuous annular rim portion, the flange may have a rim portion in the form of claws 28, see Figure 7, -to clench over on to the bead or thickened portion 7 of the nipple neck.
In the construction shown in Figure 5, the exterior of the rear portion of the annular flange employed to secure the nipple 2| to the collapsible collapsible container, a short externally tapered neck on the container containing an outlet orifice, a flange on the container having an internal annular surface opposed to the neck and tapering in opposite direction therefrom, a sepa rate member of resilient material having an extrusion slit, a neck on the said member, an internal conical surface in the neck of the separate member supported internally by the tapered neck, an external bead on the neck of the separate member, and an external conical surface on the bead complementary to and supported by the"tapering internal annular surface of the flange,rthe flange being bent over the bead and pressing it into tight contact with the tapered neck and the tapering internal annular surface 7 of the flange.
