A ribbon cord containment and identifying adaptor can be adaptively anchored or fixed to or removed from a ribbon type cord or ribbon cord of a set of earphones by hand via an anchor slot of the adaptor. The anchor slot can have a frame or structure that has an entrapment chamber and a path leading to a cord entrapment chamber where the entrapment chamber is slanted with respect to the path leading to the entrapment chamber. The structure of the entrapment chamber and path help anchor the adaptor on the ribbon type cord segment to prevent inadvertent dislodgement of the adaptor from the cord segment. The structure of the anchor slot is rigid and serves to firmly grip or compress cord segments positioned between gapped-apart opposing sidewalls within the anchor slot. When a cord containment adaptor is anchored via the anchor slot, ribbon type cord segments can be gripped into slots in a manner that helps prevent the adopter from dislodging from the ribbon cord. When positioned on cord segments, the adaptors can serve as identifying objects or adaptors.

A glass roll (1) includes a laminate film (5) taken up into a roll shape, the laminate film including a glass film (2), a protective film (3), and an adhesive layer (4), which is arranged between the glass film (2) and the protective film (3), and is configured to bond the glass film (2) to the protective film (3). A width (A) of the protective film (3) is larger than a width (B) of the glass film (2), and both end portions (3x) of the protective film (3) in a width direction each protrude with respect to the glass film (2). The width (B) of the glass film (2) is larger than a width (C) of the adhesive layer (4), and both end portions (2x) of the glass film (2) in the width direction each protrude with respect to the adhesive layer (4).

The present disclosure is directed to a reusable yarn carrier tube around which yarn may be wound at high speeds (e.g., within winding machines). The yarn carrier tube may include a pick-up groove having structural features configured to better snag yarn to initiate winding of the yarn around the cylindrical body of the yarn carrier tube. The structural features may include an adaptable snagging feature that is adaptable to many different yarn types (e.g., diameter, denier, texture, material). The structural features may include projections (e.g., teeth) with incremental narrowing therebetween in the direction opposite to the rotational winding direction. The teeth may increase in sharpness (e.g., decreasing radii of curvature) as the yarn moves further into the pick-up groove.

The tubular core (1) for tissue paper rolls consists of at least one tape (10) of tissue paper with one or more spirally wound tapes, such that the pitch of the winding helix is much smaller than the width of the tape (10) itself, so that two consecutive coils (S) are partially overlapped. In the tubular core (1) there may be several tissue paper tapes (10) wound simultaneously in relative helical coils preferably offset along the longitudinal axis of the same tubular core (1). The coils (S) of each tape (10), in the areas in which they are partially overlapped, are mutually fixed by means of an adhesive film (2) interposed between them. The adhesive film (2) is preferably continuous according to the winding direction of the coils (S) themselves. The presence of said adhesive films (2) produces a solid connection between the helical coils (S) and confers the necessary structural resistance to the tubular core (1) to receive, for wrapping on it, a tissue paper roll for hygienic use or domestic or other tape material.

A cord containment adaptor can be adaptively anchored or fixed to or removed from an earphone cord of a set of earphones by hand via an anchor slot of the adaptor. The anchor slot can have a frame or structure that may have multiple earphone cord entrapment chambers and/or an offset or non-linear path leading to an earphone cord entrapment chamber or chambers to help anchor the cord containment adaptor on the cord segment to prevent inadvertent dislodgement of the cord containment adaptor from the earphones. The structure of the anchor slot can be rigid and serves to firmly grip or compress earphone cord segments positioned between gapped-apart opposing sidewalls within the anchor slot. Entrapment chambers of the anchor slot are connected to every other entrapment chamber via cord passageways through which an earphone cord segment can pass. The cord containment adaptor may contain cord containment slots separate from the anchor slot. When a cord containment adaptor is anchored via the anchor slot, earphone cord segments can be gripped into slots in a manner that contains loose cord ends and helps prevent tangling of earphone cords when the earphones are stored or not in use. The adaptor can remain fixed to an earphone cord segment during audio listening by a user and during storage of an earphone set.

A lightweight paper tube structure capable of high loading is provided. The tube structure comprises an inner tube and an outer tube with an annular space being formed between the outer tube and the inner tube; a first paper ring and a second paper ring fitted at two ends of the annular space respectively, and a foamed body discposed in the annular space, the annular foamed body being supported between the outer tube and the inner tube. The structure enables the paper tube to retain a light weight and can also enhance the loading strength of the paper tube, thus achieving the substantial effect of preventing deformation.
