Technical Examples
- A one-piece wearable bottle opener that slips onto a persons belt, without the aid of special attachments. The preferred location to wear the opener is at either hip. The opener functions easily, using one hand, because of three features. The top section is prevented from moving outward, due to the tightened belt, the opener detail is located below the belt, creating leverage, and the lower plate section prevents the opener from moving inward, as it is pressed against the bony hip area, allowing the opener to function. The space above the opener detail, and between the belt attachment details, is used for advertising of related products, festivals, artwork and such.
- The self-opener closure comprises a spout (2) having a projecting lower rim (9) which is to be molded or glued to a composite packaging, an associated rotary cap (1) as well as a self-opener sleeve (3) arranged within the spout (2). This self-opener sleeve (3) can be made to rotate by the rotary cap (1). The inner side of the spout (2) is provided with four guide webs having varying inclines arranged over its inner circumference. These interact with specially formed guide ribs at the outer wall of the self-opener sleeve (3), which brings about that the self-opener sleeve (3), when continuously rotated in the inside of the spout (2), and by being guided at these guide ribs, describes an uneven downwardly directed movement, which superposes its rotational movement. Thus, the self-opener sleeve (3) first pierces the paper or cardboard laminate with the tip (24) of its lancing mandrel in a steep, screwline downwardly directed movement, and thereafter completes a horizontal rotational movement about 340°, whilst it cuts a circular disk out of the laminate with its sharp cutting edge, and thereafter pivots this downwards and retains it in this position.
- An opener to assist in the opening of a threaded lid from a threaded jar. The opener is a body at least partially to embrace the peripheral wall of a lid. Preferably it allows for an expansion to facilitate application, and a shoulder to be abutted by a thumb or finger to add torque to the removal efforts.
