Jan. 16, 1962 J. J. KLINGLER DEODORANT INSERT FOR TOILET TISSUE Filed Dec. 27, 1960 United States Patent O 3,017,117 DEODORANT INSERT FOR TOILET TISSUE Josef F. Klingler, Wilmette, Ill., assgnor tn Frank J. Curran Co., a corporation of Illinois Filed Dec. 27, 1960, Ser. No. 78,570 6 Claims. (Cl. Z39- 52) This invention relates to a deodorant insert for mounting within the open center of a conventional roll of toilet tissue and more particularly is concerned with an insert arrangement of tubular form adapted to receive the usual support roller or support axles provided in the conventional toilet tissue holders in general use today.
The principal object of the present invention is the provision of a deodorant insert of inexpensive construction for mounting in a roll of toilet tissue.
Another object is the provision of a deodorant insert arrangement of the above type that is convenient to install and replace and that is substantially universally adaptable to the various present day holders for toilet tissue.
Still another object of the invention is the provision of a deodorant insert arrangement which, when installed within a mounted roll of toilet tissue, presents a deodorant configuration of large exposed surface areas and which affords adequate circulation paths for encouraging volatilization of the deodorant from the exposed areas thereof.
Briefly, the invention provides a deodorant insert in the form of a tubular mounting cage having inner and outer tubular walls of open mesh configuration to define therebetween an open-sided elongated annular mounting chamber with a tubular deodorant sleeve being confined within the mounting chamber.
The tubular cage fits within the open center of a roll of tissue paper and has a central passage capable of receiving the usual mounting roller or support axles of the tissue roll holders.
Other objects and advantages of this invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same;
FIG. l is an exploded lengthwise sectional view of the elements of the deodorant insert;
FIG. 2 is a lengthwise sectional view illustrating the insert installed within a mounted roll of toilet tissue, with parts of the assembly broken away for convenience of disclosure;
FIG. 3 is an end view of the insert and is taken on the line 3-3 of FIG. 2; and
FIG. 4 is a cross-sectional view taken on the line 4'-4 of FIG. 2.
A preferred form of deodorant insert is shown herein, for purposes of illustrative disclosure, as comprising inner and outer tubular members and 11 respectively, of open mesh configuration arranged for assembly into telescoped configuration to provide a tubular support and mounting cage that has an elongated annular mounting chamber for receiving a deodorant sleeve 12.
In FIG. 2 the insert is shown in its mounted location wherein it extends through the center of a roll 13 of toilet tissue which is shown provided with the usual cardboard mounting tube 13T. The toilet tissue roll 13 with its insert unit positioned within its center bore is conveniently mounted in any of the conventional wall mounted toilet tissue holders. The toilet tissue holder illustrated for purposes of disclosure has a roller 14 that extends through the insert sleeve and has its opposite ends journalled in sockets provided in the holders spaced apart mounting arms 15. It will be apparent that holders of the type wherein the mounting arms are provided with stub axles for projection part way into the end of the ice roll are equally suitable for the insert sleeve cage of this invention.
The deodorant sleeve 12' can be tubular cakes of scented aradichlorobenzene, naphthalene, pressed wood, or the like, o-r it may comprise a tube made of plastic material, such as cellulose acetate coated with a scented solution of plastic. Alternatively, the deodorant sleeve may be a tubular piece of fiber board material, such as is used for blotters. The fiber board is treated by dipping it in a scented solution and after drying it gives ofi a fragrance to the surrounding atmosphere.
The tubular members 10 and 11 -are preferably of molded plastic material, such as polyethylene and have an open mesh configuration to encourage suiiicient circulation for inducing volatilization of the deodorant sleeve that is contained between these members.l 'I'he inner member 10 is slightly longer than the outer member and has ring shaped frames 16 and 17 of different diameter at its opposite ends for interengagement with corresponding ring shaped frames 1S and 19 on the opposite ends of the outer member for maintaining the inner member properly centered and fixed against accidental displacement.
The end frame 19 of the outer member has a series of retaining lugs 19L spaced Iabout its inner periphery and projecting inwardly to provide force fit engagement with the smaller end frame 17 at the leading end of the inner member. By way of example, the O.D. of the smaller end frame 14 may be 1.060 while the I.D. of the end frame 16 on which the lugs are formed is 1.075" and the I.D. defined by the lugs is 1.030.
The larger end frame 16 of the inner member has an annular shoulder 16S about its outer periphery for axial abutment with the end frame 18 at the entrance end of the outer member and has an exterior cylindrical surface 16C for radial engagement within the end frame 18 to maintain the desired centered relationship therebetween. In addition, axially offset abutment lugs 16L are provided to engage the deodorant sleeve.
The larger end frame 16 of the inner member has axial vent passages 16P in the form of slots or grooves spaced about the inner periphery of this frame. Correspondingly, the larger end frame 19 of the outer member has axial vent passages 19P in the form of circularly spaced openings.
The assembly of the insert unit is apparent from the exploded view of FIG. l. 'Ilie deodorant sleeve 12 is first inserted into the outer tubular member 11 and thereafter the inner member is inserted until its end frame 17 moves through and beyond the retaining lugs 19L which then prevent accidental shifting between these members.
The open mesh configuration of the cage in conjunction with the axial vent passages 16P and 19P affords adequate circulation paths within the roll of toilet tissue and the sleeve configuration of the deodorant body affords a maximum of exposed surface area for enhancing the rate of volatilization of the deodorant. These features permit the device of the present invention to function effectively even in the relatively close confines of its mounting location. In addition, the cage configuration protects the deodorant body Iagainst mechanical damage from the roller and it is easily rotatable on the roller or other supporting axle with which it is associated.
It may also be noted that while the cage may fit loosely within the roll, it will undergo sufiicient rotation with the roll of toilet tissue to develop a fanning action within the central passage of the roll for momentarily accelerating the volatilization of the deodorant body. If desired, however, the cage may fit snug to rotate as a unit with the roll.
Where the cage members are formed by injection molding it is contemplated that the polyethylene resin may be blended with pellets of pure polyethylene to which has been added a highly concentrated aroma. With vthis technique, the final molded cage members will themselves have a characteristic fragrant aroma.
It should be understood that the description of the preferred form of the invention is for the purpose of complying with section 112, title 35 of the United States Code, and 'that the appended claims should be construed as broadly as the prior art will permit.
