Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to the field of culinary implements, and more particularly to a novel set of chopsticks which incorporate an interchangeable handle and which provides for a variety of stick cross-sections suitable for grasping a variety of Asian foods. A kit is also included for transporting disassembled chopsticks in a sanitary manner so that the chopsticks and case can be sanitized and are personalized and ready for reuse.




2. Brief Description of the Prior Art




In the past, it has been the conventional practice to grasp a variety of Asian foods by the use of elongated chopsticks. The chopsticks are used in pairs and manipulated by the fingers of one hand to grasp the food and to carry the food from a dish to the mouth of the consumer. Each stick of the pair is elongated and is of a one-piece unitary construction, having a thickness at one end and a reduced thickness at the opposite end. The thickened end is held usually between the thumb and index finger of the user while the thinner elongated portion of the stick outwardly extends from the hand. In some Asian restaurants, a pair of chopsticks is provided at each place setting for the consumer to use. After the meal, the chopsticks are generally cleansed for reuse or in some instances, the chopsticks are destroyed or otherwise disposed of. Problems and difficulties have been encountered with such conventional practice in that sometimes the chopsticks are not thoroughly sanitized so that a danger resides in reuse. In other instances, the consumer may wish to use his own personalized chopsticks and to carry these sticks to a restaurant where he intends to order food. However, maintaining the sticks sanitary is difficult and because of the overall length of the sticks, carrying the sticks in a shirt pocket or coat pocket is not always convenient.




Therefore, a long-standing need has existed to provide a pair of chopsticks wherein each stick can be disassembled into separate parts and wherein the individual parts of the sticks can be carried in a case or kit for transport from one place to another in a sanitary fashion. Also, it is of great convenience to provide different shapes or sizes of chopsticks so that Particular Asian food can be grasped conveniently and in accordance with certain national customs.




SUMMARY OF THE INVENTION




Accordingly, the above problems and difficulties are avoided by the present invention which provides a novel set of chopsticks wherein each stick includes an interchangeably handle which is detachably connected to a food-engaging portion. The handle portion is provided with a deep recess at one end in order to insertably receive a stub outwardly projecting from one end of the eating portion of the stick. The opposite end includes a tapered portion which terminates in a rounded end that is intended to cooperate with the tapered and rounded end of the other stick in order to grasp and hold particles of food. Preferably, the stub and the recess include corresponding configurations so that the stub may be readily indexed with the recess and an interference type fit ensues for retaining the holder to the length of stick. In an alternate form, the stub may be threaded or have a keyway which is matable with the recess in the end of the holder.




The invention further contemplates two sets of chopsticks with interchangeable holders and wherein each set is different in that the thickness or cross-section of each pair of sticks is different in order to accommodate gripping or grasping of a variety of food products. A carrying case is also contemplated which includes a recessed insert so that the various portions and parts of the pair of chopsticks can be placed into recessed areas having the shape of the chopstick portion intended to be stored therein. The case is to be heat resistant and cleanable. A sanitizing substance may be carried in the insert material so that the chopstick utensils are ready for use upon removal from the case and assembly or installation of the holders on the eating portion of the stick.




Therefore, it is among the primary objects of the present invention to provide a novel pair of chopsticks which includes an interchangeable handle and which may readily be included in a set of chopsticks and carried in a suitable carrying case for sanitary purposes.




Another object of the present invention is to provide a novel set of chopsticks which will permit the user's choice of assembly in order to grasp or grip different types or styles of food products.




Another object of the present invention is to provide a novel set of chopsticks which includes a detachable handle portion and which includes an interference type of fit with one end of an elongated eating or grip portion.




Yet another object of the present invention is to provide a chopstick kit having a hygienic, cleanable and sanitary case for temporarily storing several sets of chopsticks such that the chopsticks are personalized and are intended to be used only by one person.




A further object is to provide a carrying case for eating utensils that is heat resistant, sanitary and cleanable as well as convenient to use, reusable and portable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, a novel chopstick eating utensil is illustrated in the general direction of arrow


10


which is of two-piece construction having an elongated member


11


terminating at one end in a rounded tip


12


which is intended to engage portions of food. The opposite end of member


11


is of square cross-section and is indicated by numeral


13


. Outwardly projecting from the square end


13


is a stud


14


which is of a special configuration. It can be seen that the major length of the elongated member


11


is tapered from the square end


13


to the rounded end


12


and the external surface of the tapered portion is smooth and unadorned.




The chopstick


10


further includes a detachable handle or holder


15


which is of square cross-section and includes a free end


16


constituting the extreme end of the chopstick when the holder


15


is engaged with end


13


of member


11


. Engagement occurs when the stud


14


is inserted into a receiving recess


17


provided in the end of holder


15


broadly identified by numeral


18


. Preferably, the shape of recess


17


is such that it will insertably receive the special shape of the stud


14


. The recess


17


in the holder


15


is of lesser or smaller dimension than the overall cross-section of end


13


or end


18


so that when the stud is inserted into the recess, a smooth and continuous surface is provided on all four sides of the assembled chopstick


10


. The midsection of member


11


integrally joining end


13


with end


12


is of tapered circular configuration as the center section merges between the two ends.




Another version of the present invention is illustrated in the general direction of arrow


21


and is a chopstick having an identical holder


15


′; however, the elongated food particle engaging member which is assembled to the end of the holder


15


′ is of a different configuration from the configuration of member


11


and the chopstick


21


configuration is indicated by numeral


22


. This configuration is substantially tapered at a greater angle than that shown for member


11


. The member


22


terminates in a rounded tip or end


23


while the opposite end is of square cross-section and indicated by numeral


24


. End


24


includes the projection


14


which is insertably received within the recess


17


in the end of holder


15


′. Again, it is noted that when the holder


15


′ is assembled with the member


22


, a smooth and mating surface occurs on the exterior surfaces of both the holder and the member


22


. To further illustrate the configuration of member


22


, it can be seen that

FIG. 3

is a square cross-section at one end


24


of member


22


while the midsection is indicated by numeral


25


and the rounded tip is indicated by numeral


23


in FIG.


5


.




It is to be understood that the chopsticks


10


and


21


are used in separate pairs. For example, two chopsticks of the configuration shown in

FIG. 1

are used in tandem for gripping and transporting food from a plate to the mouth of a consumer. With respect to chopstick


21


, it is to be understood that a pair of such sticks are used as shown in FIG.


2


and that the pair of chopsticks


21


are used for the same purpose. For example, a pair of sticks having the configuration shown in

FIG. 1

may be referred to as “Chinese” chopsticks while a pair of chopsticks indicated by numeral


21


may be referred to as “Japanese” chopsticks.




As illustrated in

FIG. 6

, an alternate fastening means for joining the opposite ends of holder


15


with the elongated members


11


or


22


is indicated and the elongated member is number


26


having a stud which is threaded, as indicated by numeral


27


. The threaded stud is threadably engageable with internal threads in the recess


14


so that the respective pieces are screwed together to effect assembly and securement. It is to be understood that other types of securement means may be provided to join holders


15


to either of the respective chopstick members


11


or


22


.




It is intended that pairs of the respective chopsticks


10


and


21


are to be personalized and used repeatedly by the same person and that the pairs of chopsticks may be carried from place to place in a sanitary environment and condition.




Referring now to

FIGS. 7

,


8


and


9


, a sanitary case is illustrated in the general direction of arrow


30


which is used to carry two pairs of chopsticks from place to place. The case includes a body


31


with a hinged lid


32


and the body


31


includes an insert of solid or foam-like material


33


that is preformed with elongated recesses to hold the respective components of the pairs of chopsticks. For example, in

FIG. 8

it can be seen that the holders


15


for each of the pair of chopsticks is stored in a recess having the same shape as the holders. The two holders are indicated by numeral


15


and


15


′ respectively. In parallel spaced-apart relationship with the holders, there are provided two pairs of elongated members, indicated by numeral


11


and


11


′ as shown in FIG.


1


and numerals


22


′ and


22


. For the holders


15


and


15


′, the pairs of members are placed in corresponding recesses so as to lie in parallel spaced-apart relationship in the insert


33


. Preferably, the insert or material


33


may be employed to hold sanitary solution or other medium which would be effective to maintain the pairs of chopsticks and holders sanitary. In this configuration, a kit is provided and the kit may be easily carried in a coat pocket, a purse or other garments worn by the user.




It is to be understood that the set of chopsticks includes at least two pairs and further includes a single set or pair of interchangeable handles which may be used for either pair of chopsticks in the set. The carrying or travel case is fabricated of materials that are heat resistant and readily cleansed so that the case is sanitary-independent of any embedded chemicals or separately included materials. The use of the chopsticks, per se, or in the carrying case are convenient, reusable and portable.




While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
