This invention relates'to a food It is aimed to providea novel structure primarily for table use. in dispensing condiments or other food, and for instance ketchup, mustard, etc.
A particular object is to provides construction having Apiston means to eject or discharge the desired quantity of material through successive depressions' and particularly a construction wherein the electing meansmay kbe disposed atr4 various elevations with respectfto .the operating ,v means or device therefor, in order that effective" discharge willresult, according to the quantity of the material within the device andthe diminution thereof. I
It is is also aimed to provide a construction which may be readily assembled and disassembled and maintained in a clean and sanitary manner.
Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying dralwing illustrating an operative embodiment.
In said drawing:
Figure l is a view of the device in elevation;
Figure 2 is an enlarged central vertical sectional view taken on the plane of line 2--2 of Figure l, and
Figure 3 is a horizontal sectional view taken on the plane of line 3-3 of lFigure 2.
Referring specifically to the drawing wherein like reference characters designate like or similar parts, we provide a jar or container as at Il, of any suitable material and for instance of glass. To the top of the glass jar III a cap I I is detachably connected as by means of screw threads at I2. Said cap may be of any desired material and for instanceis made of lucite Said cap is generally frusto-conical as shown. At the frustrum or top, the cap has' a central opening Il and spaced below the same is a wall or partition I4, for instance of Bakelite, which is secured tightly in any suitable manner against a shoulder I5 on the interior of the cap II. The wall I4 has a central opening as at I6 surrounded by an upwardly extending ange Il.
The glass jar III is adapted to contain any suitable material such as a fluid or nearly fluid condiment at I8, like ketchup or mustard, above which a follower or piston I9 is disposed. Such piston I9 is preferably vintegral with a discharge tube or nozzle 20 which extendsupwardly loosely through the opening I6 and slidably through the opening I3, the upper or discharge end of which nozzle is preferably curved'as at 2 I. From end to 65 end of the piston or tube, a discharge passage or bore 22 is provided. A gasket 23, of rubber or other suitable flexible material is carried by the piston I9 to wipe the interior wall of jar III and 5 such gasket isadapted vto be stretched so as to enter and occupy an annular groove 24 of the piston I9 as shown. An operating head for the piston and nozzle is. provided at 25 which is also substantially l0 frusta-conical and disposed within the cap II above the wall I4 and which headhas an outwardly extending lug 26, disposed in an opening A 2'IV in the cap, which is enlarged with respect to the cross section of the lug. ASaid lug is normally maintained in uppermost position through the expansive action of a coil spring 28 which engages the same and is seated on the wall Il in surrounding relation to the nozzle.
Said head 25 may be made of a somewhat re- '20 silient rubber composition in order that the wall 2'9 in its central opening, and through which opening the nozzle extends, will frictionally -and slidably engage the nozzle. The engagement of the wall 29 with the nozzle is such that 85 when the lug 28 is depressed, the tube 20 will be depressed to the extent permitted by lengagement of head with wall "thereby depressingV the piston I9 and forcing or electing the contents I8 through the passageway 22. The amount ejected 30 upon each depression is relatively small, so that a number of successive depressions are usually necessary to obtain the amount of material desired. At the same time, it is to be realized that the degree of friction between wall 2'9 and the nozzle 20 is such, that the nozzle 20 may be drawn upwardly or pushed downwardly through the head 25 in order to adjust the piston I9, according to the quantity of material I8 applied within the jar and according to the necessity for adjust- 40 ment of the piston as the quantity of material I8 diminishes.
It is to be understood, that while we have described the head 25 as made of somewhat resilient rubber, in order to afford the necessary friction t at the wall 29 with the nozzle, it is to be undererally in dispensing materials.
Various hanges may be resorted to provided they fall within:the spirit and scope of the invention.
We claim as our invention: 1. A dispenser having a container body, a pising the head, said head having friction contact with the nozzle of a degree to normally cause the nozzle to normally move unitarily with the head in both directions but to permit the nozzle to be adjusted relatively to the head, spring `means abutting and urging the head to uppermost position, a partition in the cap abutted by the spring means, said cap having an opening, and a lug extending from saidhead through said opening for engagement to depress the head. v n
2. Apparatus of the class :described including a container, means having a part slidable within the container to eject contents of the latter, a head within the container having a friction tit with said means of a degree to normally slide unitarily with said means in opposite direction through sliding of the head, saiddegree of friction being such as to premit adjustment of said means relatively to the head, the container being abutted by the head while the slidable part moves through the latter and is projected from the container.
3. A dispenser having a container body, a piston operable therein having a discharge nozzle extending slidably through one end of the body, a head through which the nozzle is slidable, said head having a portion propecting from the container body and which is depressible to depress the nozzle to eject the contents of the container body. said head being disposed within the body whereby it will abut and beheld by the body during projecting movement of the nozzle.
4. A dispenser having a container body, a piston operable therein having a discharge nozzle extending slidably through one end of the body, a head through which the nozzle is slidable, said head being depressible to depress the nozzle to eject the contents of the container body, means connected to the head and projecting from the body for manually depressing the head, said head being disposed within the body whereby it will abut and be held by the body during projecting movement of the nozzle, spring means within the container urging said head upwardly into contact with the container, and supporting means for the spring means within the container.
5. A dispenser having a container body, a piston operable therein having a discharge nozzle extending slidably through the body, a head through one end of which the nozzle is slidable, said head being depressible to depress the nozzle to eject the contents ot the' container body, said head being disposed within the body whereby it will abut and be held by the body` during projecting movement oi' the nozzle, spring means within the container urging said head upwardly into contact with the container, supporting means for the spring means within the container, said container having an opening in its wall. and a lug extending from said head through said opening for engagement to depress the head.
