ABSTRACT:
A closer and sealer for gable-topped cartons (10) of the type for holding milk and other pourable liquid and solid foods comprises a device (12) having an upper channel portion (20), a lower arm portion (22) parallel to the channel portion, and a bight portion (24) interconnecting the channel and arm portions. To use the closer after decanting food from the carton, the carton is closed by folding its integral, fold-out pouring spout back in the usual manner and squeezing together and holding the uppermost multi-layered vertical gable flaps (18) of the carton. Then channel portion of the sealer and closer is fit over and slided onto the gable flaps so as to hold them together. The sealer is slided onto the flaps until the bight portion contacts the flaps and limits travel of the sealer. The lower arm portion fits into the gable recess (16) under the flaps to guide the sealer during installation onto the carton. The upper edges of the arm portion are chamfered (36) to face the sloping inside edges of the gable recess. The channel has two pairs of facing ridges, upper (26) and lower (28), to compress and hold the flap layers together; the upper pair of ridges are more closely spaced to accommodate the narrower upper portion of the flap.
