CHICAGO, July 8 (Reuters) - Pepsi Bottling Group Inc (PBG.N) reported a higher-than-expected quarterly profit as price increases and stronger U.S. sales of carbonated soft drinks helped offset declining demand for pricier beverages.

Falling prices for aluminum also helped boost earnings, and the largest bottler of PepsiCo Inc (PEP.N) beverages said full-year profit would probably come in at the high end of its forecast even though results in the current quarter might miss analysts' expectations.

Shares of Pepsi Bottling, which remained quiet on the bid it received from PepsiCo in April, fell 0.6 percent.

While soft drinks are selling well as consumers look for less-expensive treats, Pepsi Bottling said sales volume had fallen 1 percent in the United States and Canada and 4 percent overall as shoppers cut back on other beverages, such as bottled water.

That trend could also help Pepsi's rivals, especially Dr Pepper Snapple (DPS.N), as consumers switch to sodas. Dr Pepper has a higher exposure to carbonated soft drinks than Pepsi, Coca-Cola Co (KO.N) and their bottlers, which sell a wider variety of beverages.

Dr Pepper has beaten Wall Street's expectations for two quarters in a row as consumers looking to curb spending choose its lower-priced soft drinks such as A&W and 7UP. This was also the second consecutive quarter that Pepsi Bottling beat views.

Pepsi Bottling said selling drinks at restaurants and other venues remained challenging as consumers cut back on discretionary spending.

The company has seen some success in testing new sizes of beverages sold in stores. It plans to expand distribution of a 16-ounce soda can priced at 99 cents in the current quarter.

Pepsi Bottling, which has a "positive" outlook for the remainder of 2009 and beyond, said it expected full-year earnings toward the high end of its prior forecast of $2.30 to $2.40 per share.

It also plans to raise prices after the U.S. Labor Day holiday in September, as it typically does.
