ATTOPNEV United States Patent G TOOTH-POWDER CAN CAP Ralph B. Potter, Boulder, Colo.

Application July 29, 1952, Serial No. 301,545

3 Claims. (Cl. 222-115) This invention pertains to improvements in closure caps and is particularly directed to an improved toothpowder can cap or the like.

In the dispensing and use of tooth-powder which is usually provided in a metal can with a closure cap, it is necessary to shake out the tooth-powder in the palm of the hand or on the lavatory surface then moisten the tooth-brush and place it in the palm of the hand or on the lavatory surface and then begin the brushing operation. Such procedure obviously is messy and unsanitary and time-consuming.

One of the objects of the present invention is to provide an improved tooth-powder can cap comprising a closure which has an upper powder receiving recess from which the powder may be applied to the tooth brush.

It is a further object of this invention to provide an improved tooth-powder can closure cap having a recess to receive the powder in which the tooth-brush may be readily dipped and then at the conclusion of the teeth cleaning operation, the cap may readily be rinsed under the hydrant to render it clean and sanitary whereupon it may again be applied to the tooth-powder can receptacle.

Still another object of this invention is to provide an improved tooth-powder can cap having a powder receiving portion in which the tooth-brush may be dipped and having a downwardly depending edge on its bottom surface for contacting the lavatory surface upon which it is placed while presenting the tooth-brush in the powder so that at no time does moisture get to the closure portion on the under side of the cap, said edge further serving to facilitate rinsing of the closure cap at the conclusion of the tooth cleaning operation without allowing any moisture to get on the under surface in closure portion of the cap.

Further features and advantages of this invention will appear from a detailed description of the drawings in which:

Fig. 1 is a plan view of the novel closure cap incorporating the features of this invention.

Fig. 2 is a section on the line 22 of Fig. 1 showing 'the closure cap applied to the receptacle to be closed.

Fig. 3 is a bottom view indicated by the line 3-3 of Fig. 2 of the novel closure cap.

Fig. 4 is a sectional diagrammatic view showing the device in use for applying tooth-powder to the toothbrush.

Fig. 5 is another diagrammatic view showing the closure cap being rinsed under the hydrant.

As exemplary of one embodiment of this invention there is shown the novel tooth-powder can closure cap comprising the main body portion which has an exterior surface 11 preferably conforming substantially to the shape of the outside of the tooth-powder can or other receptacle 12 with which it is to be used. The under side of the closure cap 10 is formed with a recessed surface 13 terminating in a downwardly depending lip 14 surrounding the outer edge of the surface 11 of the closure cap 10. The tapered bore 15 fits the pouring stem 16 of the receptacle 12 in the usual manner so that the closure cap 10 may be pressed on and secured in position on the stem 16.

The upper surface of the closure cap 10 is provided with a tooth-powder or material receiving depressed portion 17 which conforms substantially to the size and shape of an ordinary tooth-brush 18. To use the device the closure cap 10 is pulled off of the stem 16 of the can 12 and preferably placed on the surface 19, Fig. 4, of the lavatory 20 and the contents of the can 12 emptied in suitable quantity into the material receiving depression 17. The tooth-brush 18 is then moistened in the normal manner and placed into the tooth-powder P in the recessed portion 17 of the cap 10. At the conclusion of the tooth-brushing operation the closure cap may readily be rinsed under the hydrant 21, Fig. 5, so as to make it clean and sanitary for again returning it to stem 16 of the can 12. It is important to note that the recess 13 and the lip 14 prevent the water 22 from hydrant 21 from getting to the under surface 13 and into the bore 15 in the bottom of the cap 10. Further, the edge 14 also supports the cap when on the lavatory surface 19 With the portion 13 well above the surface 19 so that any moisture on the surface 19 will not get into the bore 15 and interfere with the clean and sanitary closing of the tooth-powder can 12.

Having thus fully described this invention and its numerous attendant advantages, it is obvious that many changes may be made in the form, construction and arrangement of the parts without departing from the spirit or scope of the invention or sacrificing its attendant advantages, the form herein describing a preferred embodiment for purposes of exemplifying this invention.

The invention is claimed as follows:

1. A receptacle closure cap for a receptacle having a discharge stem, a body member, a vertically disposed surface on the exterior of said body member conforming to the outside surface of said receptacle, a recess having a horizontal recessed surface terminating in a downwardly depending lip surrounding said recess and located around said exterior surface of said body member and including a closed stem engaging bore opening in said recessed surface adapted to engage over the stem of said receptacle to be closed, and a closed bottom tooth-powder receiving recess in the top portion of said closure cap conforming substantially to the configuration of the bristles of a tooth-brush adapted to receive powder from said receptacle.

2. A closure cap for a receptacle having a pouring stem, a closed tapered bore fitting over said pouring stern, a vertically disposed surface on said closure cap conforming to the outside surface of said receptacle, a recess on the bottom surface of said closure cap surrounding said bore, a downwardly depending lip around the outside of said recess on the lower edge of said vertically disposed surface on said closure cap, and a closed bottom tooth-powder receiving cavity in the top surface of said cap conforming in shape to the arrangement of the bristles on a tooth-brush.

3. A closure cap for a receptacle having a stern including, a cap body portion having a vertically disposed exterior surface symmetrical to the outside surface of said receptacle to be closed, means in the bottom surface of said closure cap comprising a closed tapered bore for mounting said closure cap on the stem of said receptacle, a recess in the bottom surface of said cap surrounding said closed tapered bore, a depending lip surrounding said recess located along the lower edge of said vertically disposed surface of said cap, and a depressed closed bottom material holding recess in the top surface of said closure cap adapted to receive a brush means for applying said material to the object to be treated.
