' COLLAPSIBLE TUBE HOLDER Filed May 24, 1961 ALBERT S. BAKER AGENT United States Patent 3,101,869 COLLAPSIBLE TUBE HOLDER Albert S. Baker, 422 S. Oak St., Inglewood 1, Calif.
Filed May 24, 1961, Ser. No. 112,411
4 Claims. (tIl. 222-105) My invention relates to a dispenser for pastes and the like contained in collapsible tubes.
The collapsible tube, usually formed of easily deformable metal, that is employed to package various viscous materials, such as tooth paste, hair grooming preparations, shaving cream and the like, is well known. However, this convenient package often becomes messy in use and misplaced or punctured by storage in drawers or similar places in a bathroom.
I have been able to overcome these difficulties by providing an inexpensive, yet sturdy, telescoping dispenser which adjusts to small or to large tubes and which is attachable without tools to any surface having the same contour as the rear of my device. This allows the paste to always be available at a given place, such as the inside of the door of a medicine chest, upon the wall adjacent to the medicine chest, or elsewhere as may be convenient. The fixed positioning, furthermore, allows dispensing the paste by merely pressing upon any freely available part of the surface of the collapsible tube with one or more fingers of one hand, rather than to handle the whole tube in the hands as heretofore. This simple touch" mode of dispensing is possible because I retain the collapsible tube against the dispenser assembly instead of freely supporting it therein. Thus, the reactive force to the dispensing touch pressure is supplied by the dispenser assembly and the whole is kinernatically compatible. 7
Briefly, my device is comprised of a planar support in a preferred embodiment having plural aligned transverse sections spaced from the plane of the support and also having an end at right angles to the said plane into which the outlet orifice of the collapsible tube fits. The rear surface of the planar support is provided with a strongly adhesive pressure-sensitive material for causing the support of my device to adhere to a selected supporting surface, such as a wall.
Slidably disposed within the aligned transverse sections of the support is an elongated tongue having an enlarged angled top. The top is provided with one or more slits running in the transverse direction thereof and suited to hold the flatted end of the tube. After inserting the flatted end in the slot the end is bent over as convenient. The slots dispose the flat dimension of the collapsible tube parallel to the Wall, so that the corner thereof is not a bothersome projection and so that the appearance of the whole assembly is enhanced.
An object of my invention is to provide an adjustable holder to form a dispensing device for a collapsible tube.
Another object is to provide a holder-dispenser that can be attached to any planar surface without employing screws or similar fastenings.
Another object is to provide a holder for, a collapsible tube so that the contents thereof can be dispensed by the pressure exerted by one finger.
Another object is to provide an all-plastic holder for forming a collapsible tube dispenser.
Another object is to provide a simple, durable and inexpensive tube dispensing holder.
Other objects will become apparent upon reading the following detailed specification and upon examining the accompanying drawings, in which are set forth by way of illustration and example certain embodiments of my invention.
FIG. 1 shows a front elevation of my assembled device, with a collapsible tube in place,
3,101,869 Patented Aug. 27, 1963 FIG. 2 shows a side elevation of the same, and
.FIG. 3 shows an end elevation of the same looking upward from the bottom of FIG. 1.
In the figures, numeral 1 indicates the planar support; which is the major part of my device. This is prefer-ably injection molded of high impact styrene, which gives a strong and an attractive part. A lower end 2 extends outwardly at right angles to the main part of support 1 and is provided with a U-shaped aperture 3. This aperture is proportioned and spaced so as to hold the collapsible tube firmly in place in coaction with other parts of the device when outlet orifice 4 of the collapsible tube is inserted into the aperture.
A plurality of aligned transverse sections 5, 6 and 7 are provided in the upper part of support 1 in order that tongue 8 may be slidably joined to support 1. In addition to the elongated portion of tongue 8 there is a surmo-unting angled portion 9. This extends forwardly in alignment with the oppositely disposed end 2 of support 1. This arrangement allows collapsible tube 10 to be held in my dispenser-holder. The flatted end 11 of the collapsible tube is passed through a slot 12 in the lower area of angled portion 9 of the tongue and is preferably bent over slightly as shown in FIG. 2 so as to most completely secure the tube within the dispenser. In the process of the user inserting the collapsible tube the correct vertical position of tongue 8 within the aligned sections is automatically arranged. The dimensions determining the spacing of slot 12 and aperture 3 with respect to support 1 are such as to position collapsible tube 10 against the vertical portion of support 1, particularly at the lower end of the tube, and against transverse sections 5, 6 and 7 at the upper end of the tube. This configuration provides a secure mounting of the tube in the dispenser-holder. It provides a structure in which pressure upon the front of tube 10 at any point such as 14 is resisted and the contents of the tube is dispensed through outlet 4. The configuration also results in a neat appearance.
A second and longer slot is also provided in angled portion 9 of the tongue to accommodate large-sized collapsible tubes. Slot 15 is forward of slot 12 so that the same compact structure is obtained with the large-sized tube as Was previously described. The adjustability of tongue 8 within the transverse sections 5, 6 and 7 accommodates tubes of different lengths. Collapsible tube 10 may deform slightly around the transverse section, as at 7. Such deformation takes place automatically upon the user installing the tube in the holder. It adds to the rigidity of the composite structure.
Over the greater part of the rear surface of support 1 a pressure-sensitive adhesive 16 is applied. This may be of the generic type of which Scotch tape is an example. The adhesive is protected by a piece of peelable paper during manufacture that is removed just prior to installation. More specifically, Polyken Industrial Tape manufactured by the Kendall Company, Chicago, 111., is suitable. This is a double-faced adhesive having a cloth base. A peelable plastic liner is also provided to be removed by the user just prior to installation of the device. It will be recognized that the adhesive allows very easy installation upon a number of desired surfaces Where the use of prior known screws would be diflicult or impossible. One such surface is the rear of a metal medicine chest door which carries a mirror on the front.
While the transverse sections 5, 6 and 7 have been shown fully raised from the planar surface of support 1 it will be understood that these sections may be raised only partially therefrom and a shallow groove cast into the planar surface just wide enough to accommodate the elongated portion of tongue 8.
It will also be understood that although a flat configuration of support 1 and tongue 8 have been shown, these elements may be curved in part around tube 10 or curved away from the tube, so that the dispenser can be attached to a coved surface or to a cylindrical surface, respectively. New injection molds are required, of course, for either of these alternates.
By employing high impact styrene my device is strong, light-weight and easily manufactured. No metal parts are required; thus, corrosion, expense and possible injury to the user, as occasioned by accidentally striking the device, are avoided. Various colors can be combined with the styrene molding material and so various color schemes of the surroundings accommodated.
It is not necessary that the holder be positioned to provide a vertically downward discharge of the contents of the collapsible tube, although this is usual. The bolder can be mounted for horizontal discharge of the contents, or it can be mounted at any angle dictated by the circumstances of the surroundings or the needs of the user.
The usual threaded cap, shown dotted at 18 in FIG. 1, may be replaced upon collapsible tube 10 after each use of the dispenser if this is desired. However, I have found that this is not required with the great majority of pastes, etc., that are packaged in collapsible tubes.
It will also be understood that various kinds of viscous materials may be packaged in the collapsible tube em ployed with my holder, such as medicines, paints, pastes, etc., and that my holder may be employed in factories or elsewhere where such materials are needed. My holder may also be employed with collapsible tubes of plastic, since the friction between the support 1 and the tongue 8 holds these parts together once the tube has been installed and it is not required that the flat 11 be bent over.
Still other modifications may be made in the arrangement, size, proportions and shape of my holder-dispenser without departing from the scope of this invention.
Having thus fully described my invention and the manner in which it is to be practiced, I claim:
