Abstract: The burp filtering device has the body of a writing pen, with an intake port at the upper end of the body, a plurality of exhaust ports adjacent the writing tip, and a filter disposed within the body. The filter may be made of activated charcoal or other media for filtering eructation odors. In use, the user holds the upper end of the pen body to his lips, releases the suppressed burp, and the filtered gas is exhausted through the ports at the writing tip.

Abstract: A ballpoint pen with cap has an overall length which is substantially equal to a conventional credit card enabling the pen to fit snugly in a credit card receiving pocket of a pocket book. The pen has a thin, flat body containing a writing cartridge and having opposite side edges diverging rearward in plan from a front writing end to provide a broad, flat, blade-like, hand engaging rear portion. The body also tapers in thickness as it extends outward to opposite side and rear edges forming a narrow, peripheral insertion edge. The rear end is straight and the cap is rectangular so that, when assembled, opposite ends of the pen have straight edges extending substantially perpendicularly to a longitudinal axis of the body. The body has a lateral supporting and guiding lobe for engagement with a writer's hand in different positions to facilitate a fluid writing action with different pen grips.
