A disk-shaped fastener for engaging the neck of a plastic grocery sack firmly and dependably to hold the sack in a closed condition, and which may easily be applied to the neck of the sack and easily removed therefrom; and a simple applicator for the fastener for use at the check-out stand of a supermarket for quickly and conveniently sliding the fastener over the handle portion of the plastic grocery sack into its fastening position.

Balloon stem connector for securing a balloon by its neck to the end of a stem-like object includes a wire formed slot at the end of the stem for receiving the balloon neck. A capture element having a tubular body portion is fitted in sleeve-like fashion to slide along the stem from a position where the slot is fully exposed to a captive position where it envelops a substantial portion of the loop. The capture element also has balloon positioning body portions outwardly flaring from the tubular body.

A support structure is provided for an ornament and consists of a base having an elongate stem with longitudinally spaced first and second stem parts, with the first stem part having a free end, structure for hingedly interconnecting the first and second stem parts for relative movement between (a) a first position wherein the first and second stem parts are in substantially longitudinal alignment and (b) a second position wherein the first and second stem parts are folded against each other with the free end of the first stem part closely adjacent to the second stem part, a sleeve having an opening with first and second spaced ends, structure mounting the sleeve to the base for sliding movement lengthwise relative to the stem between (a) a third position wherein the free end of the first stem part is exposed at the first end of the sleeve opening with the first and second stem parts in the second position and (b) a fourth position wherein the first stem part is at least partially within the sleeve opening with the first and second stem parts in the second position, and structure on the sleeve for maintaining the first and second stem parts in the second position with the sleeve and base in the fourth position.

A device for clamping a tubular member such as the neck of a balloon in a clip having locking arms joined by a hinge comprising an open ended channel member for receiving a sequential chain of clips and a base member to which the channel member is secured, the base member being disposed to receive clips sequentially from the channel member and having a stop against which the lowermost clip in the chain is adapted to rest. Formed in the base member between said stop and the lower end of the channel member is a notch defined by cam surfaces leading to a narrow throat communicating with a larger opening. With a clip spanning the notch and resting against the stop, and the clip hinge facing the notch, a tubular member to be clamped is positioned in the interior portion of the hinge and forced downwardly with the clip through the throat of the notch, locking the arms of the clip with the tubular member clamped within the hinge, which may then be removed through the larger opening below the throat of the notch.

The balloon closure device of the present invention includes an integrally formed flat seal portion and removable tab portion (made of biodegradable material) and a loop of string or other type of line. The loop of string may be wrapped neatly around the tab portion, which eases handling of the device before it is used to seal a balloon. Once the device is used to seal a balloon, the loop of string may be used to secure the sealed balloon to the user's wrist without requiring the user to tie a knot.
