Writing utensil structure

A writing utensil structure includes a housing having an upper end portion with a neck extending upwardly and two diametrically opposite lugs each protruding from the neck. A passage is defined in the upper end portion of the housing and extends through the neck. A cap is mounted on the upper end portion of the housing and includes an inner wall having a first recess defined in a lower portion thereof for receiving the neck, a second recess defined in an intermediate portion thereof for receiving each of the two lugs, and a third recess defined in an upper portion thereof and aligning with the passage. A writing utensil is received in the passage and has an upper end with a tip extending upwardly and received in the third recess.

FIELD OF THE INVENTION 
The present invention relates to a writing utensil structure, and more 
particularly to a utility writing utensil structure. 
BACKGROUND OF THE INVENTION 
A conventional writing utensil structure is shown in FIG. 6, and there will 
be a complete illustration in the detailed description of the preferred 
embodiments. 
The present invention has arisen to mitigate and/or obviate the 
disadvantage of the conventional writing utensil structure. 
SUMMARY OF THE INVENTION 
In accordance with one aspect of the present invention, there is provided a 
writing utensil structure comprising a housing having an upper end portion 
with a reduced diameter neck extending upwardly, and two diametrically 
opposite lugs each protruding from the neck. A passage is longitudinally 
defined in the upper end portion of the housing and extends through the 
neck. 
A cap is securely mounted on the upper end portion of the housing and 
includes an inner wall having a first recess defined in a lower portion 
thereof for receiving the neck, a second recess defined in an intermediate 
portion thereof for receiving each of the two lugs, and a third recess 
defined in an upper portion thereof and aligning with the passage. 
A writing utensil is received in the passage and has an upper end with a 
tip extending upwardly and received in the third recess. 
Further features of the present invention will become apparent from a 
careful reading of the detailed description with appropriate reference to 
the accompanying drawings.

DETAILED DESCRIPTION OF TEE PREFERRED EMBODIMENTS 
For a better understanding of features and benefits of the present 
invention, reference is made to FIG. 6, illustrating a conventional 
writing utensil structure in accordance with the prior art. The 
conventional writing utensil structure comprises a housing 50 having an 
upper end portion 51 with a threaded neck 510 threadedly engaged in a cap 
53, and a writing utensil 60 such as a pen, a pencil and the like received 
in a passage 52 defined in the housing 50. 
By such an arrangement, however, the cap 53 is mounted on the housing 50 by 
means of a threaded engagement such that a user has to screw/unscrew the 
cap 53 on/from the housing 50 so as to tighten/loosen the cap 53 on/from 
the housing 50, thereby easily causing an inconvenience when in use, 
especially in a condition requiring the pen 60 to be rapidly removed from 
the cap 53. 
In addition, the housing 50 simply functions to receive the pen 60 therein, 
thereby greatly limiting the versatility of the writing utensil structure. 
Referring now to FIGS. 1-3, a utility writing utensil structure in 
accordance with the present invention can provide multifunctions and 
comprises a housing 10 having a bowling pin configuration. The housing 10 
has an upper end portion 100 with a reduced diameter neck 11 extending 
upwardly, and two diametrically opposite lugs 111 each protruding from the 
neck 11. 
A passage 12 is longitudinally defined in the upper end portion 100 of the 
housing 10 and extends through the neck 11. An enlarged diameter chamber 
121 is defined in a lower end portion 102 of the housing 10 and 
communicates with the passage 12. 
A cap 20 is securely mounted on the upper end portion 100 of the housing 10 
and includes an inner wall 21 having a first recess 210 defined in a lower 
portion thereof for receiving the neck 11, a second recess 212 defined in 
an intermediate portion thereof for receiving each of the two lugs 111, 
and a third recess 213 defined in an upper portion thereof and aligning 
with the passage 12. 
The second recess 212 has a diameter greater than that of the first recess 
210, and a shoulder 215 is formed between the first recess 210 and the 
second recess 212 for limiting each of the two lugs 111. 
Two diametrically opposite cavities 211 are each defined in a periphery 
defining the first recess 210 and each communicate with the second recess 
212 such that each of the two lugs 111 can pass through a corresponding 
one of the two cavities 211 into the second recess 212. 
A sound diffusing opening 13 is laterally defined in the lower end portion 
102 of the housing 10 and communicates with the chamber 121. A sound 
generating member 40 includes a cover 41 securely mounted on or attached 
to the lower end portion 102 of the housing 10 by means of such as an 
adhesive, and a sound emitting nozzle 43 defined in the cover 41 and 
communicating with the chamber 121. 
Preferably, the sound diffusing opening 13 is disposed in a plane that is 
perpendicular to that of the sound emitting nozzle 43. In addition, the 
sound generating member 40 further includes a sound guiding wedge 42 
protruding from the cover 41 to be received in the chamber 121, and 
located between the sound diffusing opening 13 and the sound emitting 
nozzle 43. 
A writing utensil 60 such as a pen, a pencil or the like is received in the 
passage 12 and has an upper end with a tip 602 extending upwardly and 
received in the third recess 213, and a lower end abutting on the sound 
guiding wedge 42. 
In operation, the cap 20 can be fitted on the upper end portion 100 of the 
housing 10 with each of the two lugs 111 aligning with a respective cavity 
211 and being inserted into the second recess 212 via the respective 
cavity 211. 
The cap 20 can then be rotated relative to the housing 10 such that each of 
the two lugs 111 misaligns with and the respective cavity 211, thereby 
limiting each of the two lugs 111 by the shoulder 215 and thereby securing 
the cap 20 on the housing 10. 
The housing 10 has a well 14 laterally defined in the lower end portion 102 
thereof, and a resilient plug 30 is fitted in the well 14. Preferably, the 
plug 30 can serve as an eraser. 
In addition, a user can blow air into the chamber 121 via the sound 
emitting nozzle 43 and then into the sound diffusing opening 13 via the 
sound guiding wedge 42, thereby generating sound such that the writing 
utensil structure can function as a whistle. 
Referring now to FIG. 4, in accordance with a second embodiment of the 
present invention, the housing if includes an upper body 101 coupled with 
a lower body 103 by means of a threaded engagement, and the upper body 101 
can be used for receiving a short writing utensil 61 therein. 
Referring now to FIG. 5, in accordance with a third embodiment of the 
present invention, the sound guiding wedge 42 has an elongate extension 44 
extending upwardly with a second passage 441 defined therein for receiving 
an item such as a multi-noded pencil 62. 
It should be clear to those skilled in the art that further embodiments of 
the present invention may be made without departing from the spirit and 
scope of the present invention.
