Handle For Thermos Bottle

Abstract

A one piece plastic handle for attachment to thermos bottles including two strapped pieces which encircle the thermos bottle and can be drawn tight by utilizing the elasticity of the plastic. The straps have a plurality of attaching apertures of a generally rectangular configuration and the body of the handle has a serpentine passage with generally rectangular teeth formed centrally thereof. The strap is fed through the serpentine passage and pulled taut with a portion of the apertures engaged over the teeth. The teeth each have a sloping face in the direction from which the strap is moving when being tightened with the opposite face perpendicular to prevent withdrawal of the strap.

Description

BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The present invention is directed to a handle attachment for thermos bottle.

SUMMARY OF THE INVENTION

A one piece plastic handle attachment for thermos bottles which includes a generally U-shaped body portion having integral flexible straps extending therefrom to encircle the thermos bottle. The strap is slightly elastic and has a plurality of generally rectangular apertures formed therein to engage over generally rectangular teeth formed in a passageway in the body portion of the handle to lock the strap in its position encircling the thermos bottle.

The primary object of the invention is to provide a thermos bottle handle attachment which tightly engages the thermos bottle and cannot be removed following attachment.

Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings.

FIG. 5 is an enlarged fragmentary horizontal sectional view taken along the line 5--5 of FIG. 4 looking in the direction of the arrows with the strap shown prior to insertion in the body portion of the handle.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally a thermos bottle handle attachment constructed in accordance with the invention.

The handle attachment 10 is adapted for use with a thermos bottle shown in broken lines at 11 and being of generally cylindrical form. The handle 10 includes a generally U-shaped member 12 having body portions 13 formed on the opposite free ends thereof. A strap 14 is integrally formed on each of the body portions 13 to extend substantially perpendicularly to the U-shaped handle 12.

As can be seen in FIG. 5, a passageway 15 extends from side to side of the body 13 and has a pair of generally rectangular teeth 16 extending upwardly therein. The teeth 16 each have a sloping side wall 17 on the side thereof toward the direction from which the strap 14 is to run through the passageway 15 and an opposed face 18 which is substantially perpendicular to the bottom wall of the passageway.

The strap 14 has a plurality of generally rectangular apertures 19 extending in spaced relation therealong. The outer end portion 20 of the strap 14 is bifurcated to permit it to be fed through the passage 15 around the teeth 16 so as to provide means for grasping the end of the strap 14 for pulling it further through the passage 15.

With the straps 14 formed into generally cylindrical bands with the ends 20 engaged in the passageway 15, the handle 10 is engaged over a thermos bottle 11 and positioned as desired. The ends 20 of the straps 14 are then grasped with the fingers or with pliers and the strap 14 is drawn through the passageway 15 until the strap 14 has been stretched to a degree and the teeth 16 engaged through adjacent rectangular apertures 19 in the strap 14. The tendency of the strap 14 to return to its original shorter length causes the strap 14 to tighten securely around the thermos bottle 11 and the teeth 16 engaged in the apertures 19 prevent the strap 14 from being removed from the passageway 15 so that the attachment of the handle 10 to the thermos bottle 11 becomes permanent.

The plastic material used in forming the handle 10 can be any plastic which enjoys limited elasticity or a plastic memory that will cause it to attempt to return to its original unstretched length.

The handle 10 has been particularly described as a handle attachment for thermos bottles. However, it should be understood that it may be used with any object of a generally cylindrical nature where a handle would be desirable.

Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.

Claims

What is claimed is:

1. A handle attachment for thermos bottles comprising in combination a generally U-shaped handle member having arms and a base lying in a plane, buckle members integrally formed on the free ends of said arms and protruding laterally on both sides from said plane, a strap integrally formed with one side of each of said buckle members and extending perpendicularly of the plane of said U-shaped handle member, said straps being adapted to encompass a thermos bottle for attaching said handle member to the bottle, and means in each of said buckle members for securing and buckling the free end of its respective strap thereto, said means including a pair of separate passageways formed one in each side of the buckle member and extending therethrough for passing and receiving the free end of the strap in sequence through said pair of passageways.

2. A handle attachment as claimed in claim 1, wherein said pair of passageways are separated by but communicate with a cavity in each of said buckle members and lying in the plane of the handle member at the end of one of its arms, generally rectangular teeth being formed in said cavity and projecting from the floor thereof, and wherein said straps each has a plurality of generally rectangular apertures for engaging said teeth.

3. A handle attachment as claimed in claim 2, wherein said teeth have a sloping sidewall in the surface thereof opposite to the direction of movement of said strap through said passageways and cavity with the opposite side of said teeth being perpendicular to the floor of said cavity.

4. A handle attachment according to claim 3, wherein the free end of each of said straps is bifurcated to permit the insertion of the free end of said strap through said passageways and separating cavity past said teeth in the cavity.
