CONTAINER TUBE.

Application filed December '11, 1925. Serial No. 74,695.

Thisinvention relates to a novel and im '7 proved closure for use with collapsible container tubes of the type commonly employed to hold materials such as paints, tooth paste and the like. Such tubes are usually provided with rigid necks which are threaded to receive caps. The caps are easily lost and even when not lost are oftentimes not replaced when the tube is through being used. .The result is that the material in the tube is wasted, and, furthermore, the portion of the material exposed at the open neck becomes dried, and oftentimes the tube itself is ruptured before the material can be forced out through the neck. Various means have been devised to overcome'the above difficulties, but none of them has been entirely satisfactory.

It is the object of my invention to provlde a closure for a collapsible container tube which shall be very cheaply and easily made and applied to tubes of standard construction, and which sha l automatically close whenpressure on the tube is stopped, but which shall permit-the material in the tube to be readily forced out through the neck when pressure is applied. This means that it is possible to discard the usual cap, if desired. as it performs no useful function after the tube is once'opened for use. At

,the, same time the material in the tube is fully protected by the'closure so-as to be kept moist and so that it will consequently be in a condition to be readily forced out ofthe tube when desired- In the acbompanying drawing in which I have shown selected embodiments of my in-v vention:

Figure-1 is a view,- part1 in elevation and partly in section, of a tu e havingmy invention appliedthereto.

Figure 2 is an end view showing the top. of the tube of Figure 1. A

Figure 3 is a detailed transverse section through 'a closure, this figure being drawn on a greatly enlarged scale.

. Figure 4 is a top plan view of the structure shown in Figure 3.

Figures 5 and 6 are views similar to Figure 4 but showing modifications of my in' vention.

Referring now to the drawings the numeral 1 designates a collapsible container tube of .-well-known construction which needs no detailed description. This. tube terminates at one end in a breast 2 which is normally of. a frusto-conical shape ter- 'This tubular portion terminates in an annular flange 7 which engages the breast 2 of the tube adjacent the neck. The diaphragm 5 is provided with means to permit forcing of the material in the tube therethrough. This means is preferably in the form of one or more slits made in the diaphragm without removing any substantial portion of the material ofthe diaphragm. These slits may vary greatly in number and arrangement, and I do not desire to limit myself to any specific arrange ment thereof. For the purposes of illustration I have shown a few different arrangements which I have found to be satisfactory in actual use. In Figures 1 to 4 inclusive I have shown the two intersecting slits 8 and 9 extending diametrically across the diaphragm at right angles to each other.

In Figure 5 I "have shown the diaphragm 5 as provided with three slits 1O intersecting approximately at the center of. the diaphram, while in Figure 6 I have shown one easily as pressure is applied to the tube, and

therefore the material will pass more freely through. the neck. 'In all the forms shown it will be noted that the slits are radiating, that is, they lead outwardly from the point of intersection, and in the form shown in Figure 6 the singleslit may be considered as two slits radiating outwardly from the centre of the diaphram.

The closure may be formed of any material which is resilient enough to give, when pressure is applied to the tube, and thus to permit the contents thereof to come out and then return to normal position, after pressure on the tube is released. -At the same cemented or otherwise secured to the tube 'laid aside, the closure must adequately retain and protect the contents. Various materials lnay be used for the closure. For example, I have found that rubber is quite satisfactory, but the most satisfactory material which I have discovered is that known commercially as soft celluloid although I do not intend to limit myself to that particular kind of substance. it being obvious that other forms of cellulose material may be successfully used. This material. is as soft and resilient as rubber. but at the same time has more stiffness and strength, so that it may be made thinner than rubber, whereby it will bend more easily than a closure made of a thicker material. such as rubber.

By the use of a cellulose material such as soft celluloid it is possible to dispose the closure entirely within the bore of the neck and still have it function. That is, the ma terial may be made so thin that it will bend sufficiently without having to project beyond the edge of the neck. The advantage of this construction is obvious in that a shorter.

cap may be employed than where it is necessary to have the closure projecting from the neck. Moreover, the closure itself requires less material and is also better protected "by being completely received within the bore of the neck. In the drawing I have shown the diaphram 5 as being slightly rounded, so as to project a "very slight amount from the neck at the center of the diaphram. This form has certain advantages in'that it permits the material extruded from the tube to be wiped off, but this form is not deemed essential.

From the above .it will be apparent that I have devised a novel and improved closure which may be very cheaply and efiiciently made and applied to tubes of standard form. The closure is placed inthe bore of the neck before the material is irfserted in the tube and is retained in place by the pressure of the material against the flange 7, which pressure forces the flange into tight engage- 2 and thus prevents.

ment with the breast displacement of the closure. No other fastening means is necessary, although of course it is obvious that the closure may be and neck, if desired. In actual practice, however, I} have found that an effective seal is provided by the means which I have disclosed. When the tube is put into use,

the usual cap may. be thrown away and the tube used in the usual manner.

As-the material in the tube is extruded, the flaps formed between the slits will give sufliciently to permit the material to pass through the neck but will return-at once to the posithe breast of said tube to tion'shown in Figures 1 and 3 upon release of pressure on the tube.

I am aware that various changes in form and degree and in materials may be made in my invention without v departing from the spirit thereof. I, therefore, consider myself entitled to all modifications that may fairly fall within the scope of the appended claims.
