Artificial nipple for a nursing bottle

The invention aims to provide an artificial nipple for a nursing bottle which permits close fitting of the nipple to the sucking fossa of an infant while avoiding deformation of the nipple while providing a form that is similar to a human nipple, and which can prevent the upper and lower sides of the nipple from contacting each other during peristalsis-like movements. In view of this, the present invention provides an artificial nipple for a nursing bottle having: a nipple top part having at its tip a dispensing hole for dispensing a liquid drink; and an artificial nipple body which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The artificial nipple is made of a flexible material. The nipple top part has a rib, which prevents contact between an upper side and a lower side of the nipple top part when the nipple top part is compressed flat, at a portion where gums of an infant touch when an upper lip of the infant is in contact with the artificial nipple body or at an internal surface in the vicinity of the portion.

Method and device for inserting a food stuff into a pliable bag

InactiveUS7246641B2Easy and efficient in depositingReduce exposureLiquid fillingBlanketProcess engineeringBending force
A resilient foodstuff bag opener is disclosed, wherein the resilient bag opener is forcibly bent or bowed for easily entering a pliable food stuff bag, and upon relaxation of the bending forces, the bag opener resiliently deforms from its bent configuration to thereby open the food stuff bag in a manner that allows a food stuff residing on a food support surface of the bag opener to flow into the food stuff bag. The food support surface of the bag opener may be also used for processing foods such as cutting, dicing, washing, straining, etc. depending on the embodiment used. An inclined support may be optionally provided for maintaining the bag opener in a “hands-free” inclined position so that a food stuff provided on the food support surface can flow into the food stuff bag without a user having to hold the bag opener.
