1,481,733 A. W. PAULL CONTAINER-i Filed Jan. 19. 1923 INVENTO Patented Jan. 22, 1924.

TATES PATENT OFFICE.

ARCHIBALD W. PA-UIJL, 0F WHEELING, WEST VIRGINIA, ASSIGNOB TO WHEELING STAMPING COMPANY, 015 WHEELING, VIRGINIA.

WEST VIRGINIA, A CORPORATION OF WEST CONTAINER.

Application filed January 19, 1923. Serial No. 613,641.

To all whom it may concern:

Be it known that I, ARCHIBALD W. PAULL, a citizen of the United States, residing at Wheeling, county of Ohio, and State of West Virginia, have invented a new and useful Improvement in Containers, of which the following is a full, clear, and exact description.

The present invention relates broadly to containers, and more particularly to containers of the type usually referred to as collapsible tubes.

It has heretofore been proposed in the art to which this invention belongs to provide a collapsible tube with foraminous means extending across its discharge orifice for spreading or distributing the contents of the tube. It has also been proposed to provide a slip cover for the discharge orifice and distributing means, such cover frictionally engaging the walls of the tube adjacent the neck thereof. It was found, however, with constructions of this character, that once the tube was put in use, a certain proportion of the contents thereof remained in the meshes of the distributing means, and that this material tended to rapidly dry out and become hard and caky, thereby preventin the further efficient functioning of the tu e. The slip cover did not provide an effective protection against the drying effect of the air. Moreover, the walls of the tube adjacent the discharge. end readily became deformed, so that the slip cover would not fit the "tube tightly enough to prevent the infiltration of air to the distributing means. i

The present invention aims to overcome the difficulties above referred to by the par ticular construction hereinafter described.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view in elevation of a complete tube constructed in accordance with one embodiment of my invention.

Figure 2 is a sectional view illustrating the construction of the mouth of the tube at one stage in the manufacture thereof and prior to the application thereto of the fothe distributing means has been applied and secured in position, and also illustrating in section the cooperating cap member.

Figure l is an end view of the construction illustrated in Figure 2. t

Figure 5 is an end view of the'tube shown in Figure 3.

Figure 6 is a plan'view of the distributing member.

Figures 7 and 8 are views similar to Figures 3 and 4 of a modified form of my invention. Referring to the construction illustrated in Figures 1 to 6 inclusive,my improved tube comprises a'body portion 1 provided at one end thereof with a relatively long screw threaded neck portion 2 of slightly reduced diameter having a relatively small discharge orifice 3 in the end wall a thereof. As shown in Figure 2, a flange 5 eX- tends vertically above the end wall 4.

The distributing means is shown in Figure 6 and consists of a piece of foraminous material 6, such as This distributing memher is placed on the end wall 4 and then the flange 5 is wiped or peened over upon the member so as to cause the peripheral edge of the latter to be firmly gripped and held between the flange 5 and end wall 4. It will be understood that the tube is made of soft metal or similar material, and in wiping or peening the flange 5 over upon the member 6, said flange is tapered to a thin edge, so that it merges smoothly with the surface of the foraminous distributing member.

A screw threaded cap 7 is provided for detachably engaging the neck portion 2 for covering and protecting the discharge orifice 3 and the distributing member 6. The threaded engagement of the cap 7 with the neck 2 tends to prevent the infiltration of air to the distributing member, so that the material that has been forced out of the tube through the orifice 3 and which is held in the meshes of the foraminous distributing member, and also the material which is held between the end wall a and the distributing member, is thus protected from the drying effect of the air. In order, however, to insure the retention of the moisture in this material, the cap 7 is provided with a lining member 8 of cork or similar material,

which, When the cap is screwed on to the neck, is brought into firm engagement with the foraminous distributing member 6 and flange 5- and etfectively. seals the said member 6. i

In the modified construction shown in Figures 7 and-8, the discharge orifice 3 is greatly enlarged-and the end wall 4 is in the form of a narrow flange corresponding to the flange 5. The advantage of this construction lies in the fact that in using the tube, none of the contents thereof will be forced out between the end wall and the distributing member, sothat there will not be. formed between the end wall and the distributing member a layer of material adapted tobecome hard and caky if left exposed to the drying effect of the air.

It will be noted that in both forms of construction, the walls of the neck-ofthe tube and of; the flange joining the neck to the body 1, are made. considerably thicker than thewalls of thebody l. The purpose of this construction is a to I avoid v the. possibility of the neck portioirof the tube and the end dportion thereof adjacent the neck from becoming deformed when the tube is in useyso that the cap will alwayshave a t ght engagement With the neck portion.

The advantages of the present invention arise from the provision of a sealing member in the detachable cap for cooperation with the foraminous distributingmeans, and in the provision of a threaded engagement between the cap and neck nortionof the tube for preventing the infiltration of air to the distributing means. I

Further advantages arise from the thicks. ened construction of the Walls of theneck portion of the tube, and from lar method of securing the means in position.

1 claim:

1. A collapsible tube having a discharge orifice in an end Wall thereot, foraminous distributing means engaging said end wall and-extending across said discharge orifice, and a flange integral with said tube the peripheral edge portion of said distributing meansbeing held between said flange and end wall, substantially as described.

2. The method or" making collapsible tube, comprising providing a tube, having an aperture in an end wall thereof andvanintegral upstanding flange surrounding said orifice, arranging a foraminous distributing member on said endwall to extend oversaid the particudistributing discharge orifice, and then vbending said flange over upon said distributing member to grip the peripheral edge portion of the latter between said end wall and flange, substantially as described 3. A collapsible tube having a discharge orifice, foraminous distributing means extending across said discharge orifice, a flange integral with said tube adjacent said orifice, the peripheral edge portion ofsaid distributing means being held between said flange and a Wall of the tube, a detachable cap for covering and protecting said distributing means, and means within said cap adapted to engage said flange and seal said distributing means, substantially as described.

In testimony whereof I have hereunto set my hand.
