June 18, 1935. H. A. THORNTON COMBINED CLOSING AND OUTLET CAP FOR COLLAPSIBLE TUBES Filed June 4, 1934 F/il.
l As no 0 w 3 W1) ova "0'! Harry J. Thom ion Patented June 18, 1935 UNITED STATES PATENT OFFICE COMBINED CLOSING AND OUTLET CAP FOR COLLAPSIBLE TUBES 19 Claims.
This invention relates to a combined closing and outlet cap for the discharge end of collapsible tubes of that type whereby the contents thereof are discharged in ribbon-like-form, but it is to be understood that the cap in accordance with this invention may be employed in any connection for which it is found applicable, and the invention has for its object to provide an article of the class referred to, in a manner as hereinafter set forth to automatically permit of the contents of the tube to be discharged when pressure is applied to the latter and to automatically cut-oil the expelled part of the tube contents and to automatically close the discharge end of the tube when pressure is relieved upon the latter.
Further objects of the invention are to provide, in a. manner as hereinafter set forth a combined tube closing and outlet cap for the purpose referred to which is simple in its construction, strong, durable, compact. readily installed with respect to the discharge end of the tube, automatic in its action to permit of discharge from and for closing the discharge end of the tube, thoroughly efficient in its use, and inexpensive to manufacture.
To the above ends essentially and to others which may hereinafter appear, the invention consists of such parts and such combination of parts as fall Within the scope of the invention as claimed.
In the drawing:--
Figure 1 is a side elevation of a collapsible tube having the discharge end thereof provided with a combined closing and outlet cap in accordance with this invention.
Figure 2 is a vertical sectional view of the cap,
Figure 3 is an inverted plan of the cap,
Figure 4 is a vertical sectional view of the cap and tube, the cap being attached to the neck of the tube and in position for closing the opening for the discharge of the contents of the tube,
Figure 5 is a view similar to Figure 4 with the cap in position to constitute an outlet for the contents of the tube,
Figure 6 is a disassembled View of the cap body and sealing disc, and
Figure 7 is a vertical sectional view of the cap taken at right angles to Figure 2.
The drawing illustrates a collapsible tube 6, formed of a body I, closed at one end, as at 8, and having its other end constituting a breast 9, which terminates in a peripherally threaded annular neck Ill. The latter at its outer end has its inner face formed integral with a fiat disc I I, provided with a diametrically disposed slot I2 constituting a passage for the contents of the tube 6 when pressure is applied to the latter. The slot I2 provides for the contents of the tube 6 to be discharged therefrom in ribbon-like-form. The threads on neck ID are designated I3. 5
As is generally well known, a collapsible tube of the type referred to includes a removable cap, not shown, which engages with the neck III for closing the slot I2. When the contents of the tube are to be used, the cap is removed and pres- 10 sure is applied to the tube for the purpose of expelling a part of the contents of the latter through slot I2. After the expelled part has been utilized, the cap is restored to its position on neck ID to close slot I2. Now with respect to the cap, in ac- 5 cordance with this invention, it forms a permanent part of the tube, and when it is desired to expel a part of the contents of the tube, it is not necessary to remove the cap, as the latter automatically functions to provide a closure for the discharge end of thetube and an automatically opening and closing outlet for the contents of the tube.
The cap in accordance with this invention may be an original part of the tube, or the latter may be set up with the ordinary form of cap which is to be removed by the user of the contents of the tube and the cap in accordance with this invention substituted. Preferably the cap as herein set forth will form an original and permanent part of the tube and be formed with a removable or severable sealing agent to be referred to for temporarily closing the outlet provided by the cap.
The cap, in accordance with this invention, and generally indicated at I4, includes a resil-fi ient body I5 of a rubber formed of a hollow coupling portion I6 of uniform outer diameter, a hollow tapered portion I1 and a flat outer end portion l8 of disc-like form integral with the inner face and flush with the end edge of portion H8. The portion I'I provides a receiver or chamber which is normally closed at its outer end by the portion I 8. The inner face of .portion I6 is threaded throughout. The body I5 is formed with a pair of spaced parallel oppositely disposed segmental parts I9, 20 lengthwise thereof extending from the inner end of portion I6 to the outer end of portion II. The inner faces of parts I9, 20 are straight or perpendicular with respect to the axis of the cap. That portion of each of the parts I9, 20 fonned by the portion I'I gradually decreases in width from the portion I6 to the portion I8. The body I5 is also formed with a pair of spaced oppositely 5 disposed segmental parts 2|, 22 extending from the inner end of portion IE to the outer end of portion I'I, having oppositely curved inner faces. That portion of each of parts 2|, 22 formed by the portion slopes inwardly from the portion' Hi to the portion I8. The parts 2|, 22 are ofless thickness than that of and are alternately disposed with respect to the parts I9, 20. The setting up of the parts I9, 20, 2| and 22 in the manner as referred to provides the interior of body l of substantially oval contour. The portion l8 at its center is formed with a normally closed slot 23 disposed diametrically thereof. The portion I8 is of less thickness than the portions l6 and I1. Arranged within the body I5 is a pair of oppositely disposed ribs 24, 25 which are arranged in endwise opposed alignment and gradually decrease in width towards each other, The ribs are arranged at right angles to the slot 23, are integral with the lower face of portion l8 and have their larger ends integral with the inner faces of the parts 2|, 22. The ribs have their smaller ends arranged substantially at the sides of slot 23. The ribs are disposed at a diametric center of portion i8.
The chamber provided by portions l1 and I8 'is designated 26' and when the body part 1 of tube 6 is collapsed the contents of the tube will be forced into said chamber.
The manner of setting up the parts I9, 20 and ribs 24 relative to the parts 2|, 22 and portion l8, provide, when the portion I6 is secured to the neck In, for the side walls of slot 23 to abut throughout for the purpose of closing the latter and whereby body I5 will appear as is shown in Figure 4. When pressure is applied to tube 6 for the purpose of expelling the contents thereof, the latter acting against portion l8 will distend it in the manner as shown in Figure 5 whereby the side Walls'of the slot are spread apart to form an outlet for the material from the tube. When pressure is relieved upon the tube, the side walls of slot 23 will move to abutting relation thereby cutting off the expelled material which is outwardly of portion l8. Due to the resiliency of body I5 and the inner contour of portion l6 when the latter is applied to neck II] for permanent connection thereto, a pull will be exerted on parts I9, 20 when portion I6 is made to snugly encompass throughout said neck I0, and this action causes the side walls of the slot 23 to be held in abutting relation until pressure is applied against the inner face of portion H3.
The cap has a part thereof provided with a removal seal 26 in the form of a thin disc 21, which is molded to the outer face of portion I8 whereby the slot 23 in the latter is sealed. When it is desired by the user to have access to the contents of the tube, the seal 26 is removed permanently from portion Hi.
