The improved cap retaining means improves the manageability of the instrument such that the cap means can be removed and lodged into its open position by a continuous motion of the hand which is holding the instrument.
Description
21~24~7 BACKGROUND OF THE INVENTION
Marking pens have become a commonly used writing implement because of their versatility and unique marking characteristics. They are not only used by artists and students, they are commonly used in many businesses whenever a bold or highlighted entry is necessary. Improvements in the ink, writing tips, and m~mlf~cture have progressed steadily to produce low cost, high quality writing implements. A principal advantage of marking pens is their ability to employ porous felt tips having a variety of di~elelll colored inks.
Nevertheless, conventional marking pens have several inherent deficiencies. One of these deficiencies is the requirement that the pen's inked tip, generally porous felt impregn~ted with ink, must be kept covered when not in use. Because the inked porous tip of many marking pens has a tendency to dry out when left exposed to the atmosphere, these pens have a separate cap for covering the felt tip when not being used for writing. Quite often, users of the pen have a tendency to remove the cap carelessly and set it aside. When it is time to replace the cap, the user spends several irritating seconds searching for the cap. This is particularly annoying when the user is busy and concentrating on performing his or her duties.
Thus, the ink-impregnated porous tip of conventional marking pens has created a dilemma not encountered by other types of writing implements such as pencils, colored wax, and the like. Heretofore, a convenient method of keeping track of the cap used to cover this felt tip portion of marking pens has not been available.

EMBODIMENT OF T~E PRESENT INVENTION
In accordance with a preferred embodiment of the present invention, disclosed ismarking pen 10 having a substantially cylindrical elongated body portion 20. Thecylindrical body portion can be made of any durable material and is preferably made of plastic material. The cylindrical body 20 has a first end 22, a second end 24, and a passageway 26 extending longitudinally from the first end 22 to the second end 24. A
writing element 28, preferably one having a tendency to dry out when exposed to the atmosphere such as a porous ink impregn~ted felt strip, is generally disposed within this passageway 26 and extends outwardly from the first end 22 of the body 20. The tip of the writing element is generally beveled as clearly shown at 29 in FIGS 2,5,6 and 9 to facilitate writing.

DETAILED DESCRIPTION OF TIIE PREFERRED
EMBODIMENT OF T~E PRESENT INVENTION
In accordance with a preferred embodiment of the present invention, disclosed ismarking pen 10 having a substantially cylindrical elongated body portion 20. Thecylindrical body portion can be made of any durable material and is preferably made of plastic material. The cylindrical body 20 has a first end 22, a second end 24, and a passageway 26 extending longitudinally from the first end 22 to the second end 24. A
writing element 28, preferably one having a tendency to dry out when exposed to the atmosphere such as a porous ink impregn~ted felt strip, is generally disposed within this passageway 26 and extends outwardly from the first end 22 of the body 20. The tip of the writing element is generally beveled as clearly shown at 29 in FIGS 2,5,6 and 9 to facilitate writing.
2~32487 .
Disposed on the first end of the cylindrical body 20 is a cap member 30 for making a closure over the writing element 28 when not in use. The cap has a body portion 32 which is generally complementary in shape to the first end 22 of the cylindrical body 20 of the pen. The cap member has a closed end 31 and an open end 33 for sliding over the first end 22 of the cylindrical body 20 when it is desired to cover the tip of the writing element 28.
Extending outwardly from the perimeter ofthe open end 33 ofthe cap member 30 is an elongated arm 34 which pivotably joins the cap member 30 with the elongated cylindrical body 20 of the pen. The arm 34 extends a distance from the open end 33 sufficient to permit the cap member 30 to be slidably removed from the end and pivoted downwardly to engage the cap receiving area adjacent the second end 24 of the cylindrical body 20 as shown in FIG 2~
The cap member 30 further includes a means for removing the cap from the pen body 20 with a person's finger. This cap removing means is preferably a projection 36designed to accommodate a finger as shown in FIG 2. It is understood that the projection 36 shown here is merely illustrative ofthe various configurations sufficient to facilitate removal of the cap from the pen while holding the pen in one's hand.
Opposite the cap removing means is at least one cap retaining means for retaining the cap in an open position after removal from the writing element. Preferably the cap ret~ining means are two ridges 46 and 47 which are adapted to engage grooves 62 and 64 disposed on the walls of channel 52 on the lower end of the cylindrical body 20 as shown in FIGS 2, 4 and 9.
The arm 34 extending from the cap 30 has a first and second projection 42 and 44extending outwardly and in opposite directions from the terminal end 43 of the arm.
These projections 42 and 44 are adapted to engage channels in the cylindrical body 20 and pivotably move the cap from a closed position to an open position as discussed in detail below.
The cylindrical body has a continuous groove 52 extending longitudinally from the first end 22 of the body to a position at or adjacent the second end 24 of the body.
Disposed adjacent the sides of the groove 52 is a pair of channels 54 and 56 which are adapted to engage projections 42 and 44 at the terminal end 43 of the cap arm 34. The length of the channels 54 and 56 can vary, and will be long enough to accommodate the cap arm as it is pivotably and slidably positioned between an open and closed position.
In operation, the cap can be removed from the end of the pen by pressing on the projection portion with one's finger. The cap is displaced upwardly from its seated position on the end of the cylindrical body until it clears the tip of the writing element.
The cap is then pivoted downwardly along the side of the cylindrical body until it reaches the cap receiving area where is it secured in its open position. When it is desired to return the cap to its closed position, the cap is pivoted upwardly and slid along the groove until it can cover the writing element again.
Although the present invention has been described in detail and with specific reference to its preferred embodiment, it will be understood by those skilled in the art that various modifications and changes can be made thereto without departing from thespirit and scope of the invention.
