A rials frequently contain acid ingredients which corrode the parts and prohibit their free movement which is necessary in discharging a uniform ow of material. Furthermore inthe use of such closures heretofore employed where the materials are ejected or dispensed from a side opening,` it has been difficult to distribute the material evenly on a brush or other receiving object, because of :the projecting end member or protuberances extending beyond the dispensing portion of the cap.

One of the features of the present invention is the provision of a c ap which shall be particularly adapted for dispensing fluent material longitudlnally from a collapsible tube container having a central passage anda tubular member slidably mounted in the passage. The tubular member is provided with a closed top and a side delivery opening directed obliquely to the longitudinal axis of the cap. It will thus be noted that the relative movements of the tubular member and the cap cause the fluent material to be ldischarged longitudinally ofthe cap and not side ways as heretofore experienced in the dispensing caps now in general use. Another feature of this construction is that the ribbon of fluent material may be caused to flow uniformly from the end of the closure member and this is of particular advantage in distributing a ribbon of material such as toothpaste on a brush, for example.

Referring more particularly to the drawings, there is shown in Figs. 1 and 2 a novel form of closure embodying my invention. In this illustrated embodiment, a collapsible tube Il) having a threaded nozzle II is closed by a cap I2 and a tubular member I3 slidably mounted in the central passage of the cap I2. It will be noted that the top wall closure for the tubular member has-the same general conguration as the top contour of theV cap I2. In other words, I prefer that the cap I2 shall be of dome shape so as to provide a neatly appearing closure which shall minimize any tendency for waste paste to collect around the end"'parts and dry or corrode in such a manner that frequently renders caps of this nature inoperable for the purpose intended. Near the top portion of a tubular plunger is a side oblique opening I4 forming one of the principal features of myA invention. It will be noted that this opening is at the top of the slidable plunger and slopes upwardly and outwardly at about y degrees from the axis of the closure cap. When pressure is applied to the uent material in the tube, it rises upwardly into the plunger I3, raising the same to cause the opening I4 to pass material obliquely and in ribbon form longitudinally of the closure. In order to limit the yupward travel of the plunger member, the lower portion thereof,

is provided with a flange or other suitable stop member I5.

To further provide:` for the slidable movement of the tubular member I3 in the passageway of the closure I2, an annular gasket I 6 is located y on the tubular member so that it shall engage the inner cavity of the cap. 'Ihis gasket serves to regulate the movement of the tubular member and thereby facilitate the operation of the tubular member to dispense a uniform flow of fluent material.

Referring to the modifications shown in Figs.

`3, 4, and 5, the cap I2 is provided with a tapered recess .I'I around the central passage. In this embodiment of my invention the tubular memlber I3 is provided with a tapered ange portion I8 at the top thereof which shall conform to the recess in the top of the closure so that when the tubular member is retracted, the contour of its top shall conform to that of the cap and thereby provide the same general neat yappearance as heretoforev described. In this embodiment of the invention the tapered flt between the cap end and the. tubular member is sealed by means of a 'gasket I9 provided in the fianged portion ofthe tubular member. 'I'his gasket forms an air `seal and thereby prevents any leakage of air to thematerial and thereby eliminates any cakng or corroding 'effects of the material.

yspring 20, the contents of the tube are effectively sealed against any ingression of air.

Another feature of the present` construction is .the provision of lmeans for twisting the tubular member I3 simultaneous with its longitudinal movement. This movement is accomplished by an incned slot 2| provided in the tubular member I3. Arranged to engage the slot is a pin 22 mounted in the lxed portion of the cap. It will thus be noted that as the cap moves upwardly it will be given a rotary movement and this movement is very desirable because it minimizes any sticking elTect caused by dry or caked materials. 'I'his rotary movement also causes the relative movement of the orifice surfaces and thereby permits a uniform flow of material from the cap ,outlet.

Inthe handling and shipping of collapsible containers of the character designatedit frequently happens that the tubes are accidentally squeezed and the material discharged and I overcome this diiculty by providing a. retainer which shall grip the cap and engage the top of the tubular member to prevent its outward movement. The retainer of this type comprises an upright member 2l and an angular member 25 at the top portion thereof. The lower portion is provided with an angularly disposed fork-shaped member 26 Which is adapted tov engage the neck of the tube and the cap and thereby positively hold these parts in position to prevent any accidental discharge of material.

While I have shown the retainer 26 in the form of a detachable metal clip which grips the cap and tube neck, it is obvious that the detachable retainer may readily be made in other forms to perform the same function. For example, a covering of cellophane or other similar material indicated by numeral 24', mayv be secured over the cap and thus prevent the accidental discharge of material as Well as keep the cap in a sanitary condition during shipment.

It will be further noted in the illustrated embodiment of the invention shown in Figs. 4 and 5, that the tubular closure member I3 automatically closes the opening I4 by the action of spring 20, when the pressure on the container is released. By providinga sealing gasket. of cork or other yieldable and non-corrosive material, any adhesion or sticking ofthe tubular plunger lI3 to the cap I2, is reducedv to a minimum because the material in the cap is sealed against any ingress of air andfurthermore the external metallic joint usually employed and exposed'to the air, is eliminated by this gasket seal. In other words, the gasket I9 is yieldably held in sealing relation with the top peripheral edge of the cap central passage, by means of the spring 20. The cap is thus automatically retainedin closed position, except when fluent material is actually being dispensed and any opportunity for material to collect and dry on the closure joints and cause the same to stick, is reduced to a minimum. If for any reason the cap closure should stick, the rotary or twisting movement imparted thereto by the pin 22 and angularly disposed slot 2|, immediately releases the same as soon as pressure is applied to the contents of the container.

Referring to the modication shown in Figs. '7 and 8, the movable parts are located entirely within the contour of closure capv I2 which is rigidly mounted on the neck or nozzle of the container I0 by a friction or.screw connection as heretofore described.

In this embodiment of the invention, the cap 2'I is provided with a. central passage 28 into which is slidably tted a tubular membery29, closed at the top and punched with an oblique side opening 30 near the top wall. Located in the cap 2'I and near the top thereof is an oblique opening 3I vwhich registers with. the opening 30 when the tubular memberlis moved into dispensing position by pressure applied to the container or collapsible tube tor which it may be attached.

'I'he tubular member is retained in a closed position byr a spring 32 anda stop- 33 formed on vthe inside' of the cap 21. `In order to facilitate it is twisted at right angles so that the flanged bottom of the tubular' member 29 shall rest on vthe stop and limit the inward 4movement caused by thespring 32.

` It willthus benoted that the wall discharge vopenings and 3 I are inclined obliquely at about 45, degrees andthus permit the discharge of material obliquely to the axis of the cap and near the vtop'sok that a uniform flow of material shall be dispensed from the end of the cap.`

The cap 29 'is fitted to the container nozzle or stop by a taper frictionf'joint 35 and secured in this positionby a bayonet joint connection indicated by pin 36`and angularslot 31.

Another-'feature of ythepresent invention is the provision of a massage device 38which shall be attached to the topA of `a tube or container of shaving cr'eam'orv other lotion as shown in Fig.I 9. In this embodiment of thev invention the closure is 'similar to `-that heretofore described and adapted to Adispense a ribbon of cream' or fluent material from the top of the closure.

The massage device38 comprises a plurality of angularly disposed soft rubber ribs positioned adjacent to the tube openingIII.V The device is supported by a suitable bracket support 39 secured to the neck of the container I0. The arrangement is suchthat as the proper amount of cream lis discharged on the rubber ribs, the supply is cut offgby the return movement of the tubular memberwhichacts as a-valve cutoff. A bail member 40 is xed to the cap so that the ysame Emay swing over the 'top o1' the tubular "member and retain the same in closed position when the massage device is being used. The bail is :detainedv in position by'a pair of knobs 4I-4I which permit the bail to snap into position and prevent any accidental discharge of material when the 'massage device is being used. These precautions are taken because in a device of this kind, the -tube container for the massage fluid or creamr is used asthe handle for the massage .device and any 'undue pressure would cause lthe material to actuate the tubular member and dispense material when it is not wanted and thereby be very wasteful of material aswell as'open to the'objection of having excess material present.

The Vbail 40 engaging the top of the tubular vmember also provides a valve shut-off for fluent lform manner. f

material which shall positivelycontrol the amount of material dispensed. y f

In the rmodification shown in Figs. 11 and 12 vthe massage device 331s mounted directly on the cap I2 in a dove-tail shaped slot 42. L'I `he member Sais reinforced bya rib member 43 which `may be of 'metalor other rigid material.

from the end of theclosure The closure members heretofore described are to al paper'collapsible container k43.

separable units which may be applied to the nozzle of any standard tooth paste or shaving cream collapsible tube container. Whichever form of closure is employed, the closurel parts may be made of-metal, or metal coated with paraffin, or the closure'parts I2 and I3 may be made of nonmetallic material such as hard rubber, bakelite or plastic material. I have found that bakelite material is very suitable for caps of this character as it eliminates any deleterious effects of corrosion and is most desirable from an artistic standpoint as closures made of bakelite may be made in many attractive color designs. 'I'he cap I2 may be made of black material and the tubular plunger I3 of a contrasting color, such as red, and appearing at the end of the cap as a red dot.

'I'hese color contrasts may be used to designate the nature of the material contained in the tube. For example, the red dot may indicate 'tooth paste, anda green dot may indicate shaving cream,'etc. If the cap is covered with cellophane or other transparent material for protection` or sanitary reasons as heretofore described, the contrasting colors are still visible to make a vmore attractive and suitable commercial package.

Referring to the modification shown in Figs. 13 and 14', there is shown a cap constructed in accordance. with the present invention and applied One of the important features of this novel construction is the manner in which thecap I2 is secured to the neck portion of the paper container 43.' Located at the upper portion of the paper tube is a neck ring or annular member M provided with external threads'45. The threads 45 are complementary to the threaded portion of the cap I2, and the paper material is positively secured between these threaded portions. In assembling the parts, the sides of the paper tube maybe crimped over the top of the neck ring 44 as shown at 46 and thus enable the parts to be readily assembled as well as provideV additional'holding material. The lower portion of the neck ring 44 is beveled as indicated at 41 toprovide a minimum resistance to the flow of material. The inner lower portion of the plunger I3 is beveled in a similar manner as indicated by numeralfl. f

One of the important features of the-present construction is that the paper sides are positively and neatly secured to the cap and neck members by mechanical connection and without the aid of any external clamping `members or the application of any adhesive material which may disintegrate and subsequently result in damage by the separation cf the paper from the cap parts.

Referring to the modification of the cap construction shown in Fig. 15, the dome-shaped cap I2 is designed and constructed to receive a yield- .able dome-shaped member 49 arranged to t within thecap and perform the dispensing operation when pressure is applied to the contents of the container and automatically close when the pressure is released. This member is preferably made of pure gum rubberand arranged with a. relatively thick, portion 50 at the top of the cap which is adjacent the tubular passage opening.

,The lower side walls of the dome are tapered or thin as indicated at 5I so that they may be clamped between the cap threads and the neck threads of the container. The lower rim of the rubber walls protruding beneath the lower rim of the cap I2 isprovided with a rim or thick portion 52 which prevents the rubber from accidentally becoming loosened or otherwise separated from Athe adjoining members.

Another feature of this particular construction is the provision of an annular space 53 between theupper thick portion 50 and the top portion of the cap I2. This space is necessary to provide for the proper action of the rubber to enable the cap to readily dispense fluid. I

One important feature of providing an internal dome-shaped dispensing member of a good quality rubber is that corrosion is eliminated and caking reduced to a minimum. Another important feature of this novel construction is that the contents are positively sealed and all damage or waste from accidental discharge in shipment or otherwise is eliminated as is frequently the case in mechanical caps now in use.

In operation, when it is desired to use the contents of the container, the central thick lportion of the dome is punctured by a sharp instrument 54 as indicated by the dotted line 55. One form of a convenient instrument which may be packed with the container is shown in Fig. 16, and indicated by numeral 56. In Fig. 17, the puncturing instrument 54 is shown provided with a yieldable clamp portion 5l which may be attached to the neck of the container I0 so that there is no danger of it becoming lost during shipment of the product.

The distributing or massage device shown in Fig. 18 is particularly desirable for applying massage and facial creams without handling the material with the hands. For example, in applying certain shaving creams it is necessary to use the fingers and this necessitates washing the hands before handling the razor for continuing the shaving operation. To obviate this inconvenience, I provide a brush distributor comprising a thick rubber base 58 and long rubber projections or bristles 59. This distributor is secured to the container cap at an angle of about 45 degrees by suitable bracket members 60 and 6| respectively.

An aperture 62 is provided at the central portion of the distributor for passing material to the rubber projections 59. In this particular construction, the cap l2 is provided with an annular upper rim portion 63 which shall fit the aperture 62 and prevent uid from leaking downward past the cap in an objectionable manner Another feature of this particular construction is that the plunger I3 normally projects through the base portion of the distributor. This construction aids the operation of the plunger and causes it to be positively forced inward when the distributor or applicator is applied to the person. Thus there is provided anautomatic applicator which only utilizes or dispenses fluid when actually needed or intentionally applied and cannot be accidentally wasted.

To further aid in distributing the material and permit ready cleaning of the applicator, the end portions of the base are sloped downward and outward as indicated by numerals 6l and 65 respectively.
