Description
April 1965 J. B. ALLEGRAUD ETAL 3,179,299
COLLAPSIBLE CONTAINERS Original Filed Sept. 6, 1962 INVENTORS JEAN BAPTISTE ALLEGRAUD a BY VICTOR OLLIVRY M 41L M ATTORNEYS their United States Patent ()fifice 3,179,299 Patented Apr. 20, 1965 This application is a continuation of the application Serial No. 221,853, filed September 6, 1962.
The invention relates to collapsible containers, for example resilient collapsible tubes.
Resilient collapsible containers have the well-known disadvantage that when they tend to recover their original shape after a portion of their contents has been squeezed out, air is sucked in. When the contents of the container consist of a substance susceptible to desiccation or to oxidation, such air not only affects good conservation of the product but also hinders satisfactory dispensation from the container. Owing to the presence of air, the contents on exertion of pressure on the container do not emerge immediately and when they do a stream is formed which is not continuous but which is interrupted by air bubbles. Moreover, the air bubbles bursting are apt to spatter the contents in all directions.
It is an object of the invention to mitigate or obviate the above-mentioned disadvantages in the use of resilient collapsible containers.
According to one aspect of the invention a resilient collapsible container is provided comprising a body portion to contain a substance to be dispensed, a head portion defining a passage through which the substance can be disepnsed, and an apertured diaphragm across said passage at a position inward from the outer end of said passage, the arrangement being such that after some of said substance has been dispensed and the container starts to resile,
a quantity of said substance on the outside of the diasage ata position inward from the outlet, the arangemerit being such that any of said substance outside said diaphragm and in said passage will hinder the sucking back of air in said body portion.
According to yet another aspect of the invention a resilient collapsible tube is provided in which an apertured diaphragm is disposed across the passage through the nozzle of the tube at a position inward from the outer end of the nozzle to hinder the sucking back of air nto the tube after any of the tube contents have been dispensed.
Owing to the presence of a quantity of said substance covering the outer side of the diaphragm, at least initially such substance will tend to be sucked in rather than air, so that air will be prevented from being sucked back into the container at least for a time which should be sufficient to allow the user of the tube toreplace the cap. Thus this measure can ensure that little or no air is present in the body of the container which would have to be driven out before thecontentsof the container could be subsequently dispensed.
Preferably the diaphragm is at the inner end of said passage, however, this isnot always essential provided there is a sufficient cavity in the passage, outward of the aperture, to enable the invention to be achieved.
The diaphragm can be convex inwards or outward.
A larger area will then be available in which to arrange the aperturing.
If the diaphragm is convex towards the interior and the aperturing is in the form of several openings, this arrangement promotes coalescence of the streams which will emerge from each opening during dispensation, particularly if these openings are arranged near the periphery of said diaphragm.
The aperturing can be provided by one or more slots, which have considerably greater length than width. With this arrangement it is preferred that the diaphragm be convex outwards because then each slot can readily open out when the contents are dispensed.
An insert can be provided to promote coalescence of streams emerging from the aperturing of said diaphragm.
The outer end of said pasasge can have a reduced diameter. With this arrangement the or each stream which will emerge from the aperturing when dispensing will more nearly fill the cross-sectional area of the outer end of said passage. This will tend to drive out any air in said passage and allow the contents to be more evenly dispensed. If the aperturing is in the form of a plurality of openings, said reduced diameter can cause the streams which emerge from said openings to coalesce. The outer end of said passage can be provided with such a reduced diameter that the contents can be dispensed drop by drop.
The arrangement of the diaphragm and said passage can be such that any off-centre stream of substance which emerges from said apertured diaphragm during dispensing, will be deflected towards the axis of said passage, so
as to promote coalescence. For example, the passage can have an annular inward projection, of t which the side facing the diaphragm has an annular recess on which the streams can impinge.
Several embodiments of the invention will now be described, by way of example, with reference to the accompanying diagrammatic drawings, in which:
FIGURE 1 shows the discharge end of a collapsible tube in axial section;
FIGURE 2 is a similar View of a second embodiment;
FIGURE 3 is a similar view of a third embodiment;
FIGURE 4 is a similar view of a fourth embodiment;
FIGURE 5 is a similar view of a fifth embodiment;
FIGURE 6 shows a similar view of a sixth embodiment; and
FIGURE 7 shows a similar view of a seventh embodiment.
The collapsible tube shown in FIGURE 1 is made of thermoplastic material and comprises a body portion 1, shoulder 2 and a head portion 3 provided with an external screw thread 4 for a closure cap (not shown). The head portion 3 has a passage 5 through which contents of the tube can be dispensed and an apertured diaphragm 6 across said passage at a position inward from the outer end of said passage, in this case the inner end thereof.
The diaphragm 6 is apertured by provision of a number of small openings 7 arranged so that on squeezing the tube, the contents, as separate streams, pass from the interior of the body 1 through the openings 7 into the disof a quantity of these contents on the outer side of the diaphragm prevents any air being sucked back into the tubebody portion-1. Thus, on release of the pressure exerted on the tube, sucking of air into the body portion 1 is delayed for a sufiiciently long period of time to allow the user of the tube to replace the closure cap.
The embodiments shown in FIGURES 2' to are provided with diaphragms which are convex towards the interior of the body portion. In FIGURE 2 the diaphragm is cylindrical, in FIGURE 3 it has the shape of a truncated cone, in FIGURE 4 it is conical and in FIGURE 5 the diaphragm is spherical. The convex shape of the diaphragm makes a larger area available in which to arrange the small openings 7. Moreover, by arranging the majority ofthe openings near the periphery of the diaphragm 6, formation of a single solid stream from the separate thin streams which emerge through the openings is furthered. Formation of a singlestream is also furthered by provision of an insert 9 in the outer end of the discharge passage, as shown in FIGURE 6. This insert 9 has a central opening 10, the radial dimensions of which are smaller than those of the discharge passage of the tube. if the dimensions of the opening 10 are small enough the tube can be used for dispensing its contents drop by-drop.
In FIGURE 7 anotherf-orm of insert is shown. This insert 10 has an annular inward projection, of which the side facing the diaphragm 6 has an annular recess 1-2.v
The thin streams of material extruded through the narrow openings 16 arranged near the periphery of the diaphragm 14 impinge on the annular recess 12 and are deflected towards the axisro-fthe discharge passage, whereby the formation of a solid stream of substance and expulsion of air present in the chamber 15 is assured. The central opening 111 may be flared as shown in the drawing when it is desired that a thick stream of material is to be dispensed.
In an example of the invention toothpaste of viscosity 40,000 centipoises was contained in a tube having a conical diaphragm similar to that shown in FIGURE 4. The cone was directed inwards and had ten apertures of 1 mm. diameter, six. being situatedat the peripheral base of the cone and four further up the walls of the cone.
in a second example similar toothpaste was contained in a similar tube, however, only six apertures in the cone were provided this time, each being of -1 mm. diameter and on the walls of the cone.
In a third example liquid shampoo having a viscosity of 4,000 centipoises was contained in a tube having a cylindrical diaphragm directed inwards and similar to that shown in FIGURE 2, Two apertures, each of 0.5 mm. diameter, were providedin the curved surface of the diaphragm.
