Description
FIELD OF THE INVENTI _ This invention is generally concerned with a container handle and, more particularly, with handles for holding and positioning cans or similar containers for a variety of products.
BACKGROUND OF THE INVENTION
Presently used cans of this type, such as paint cans, are equipped with a metallic bail handle which is hooked to two diametrically opposite elements welded to the body wall of the can. One disadvantage of a metallic bail handle is that the wall of the can must first be treated and coated to avoid any welding with corrosion parts of the can. Additionally, the label that goes on to the body wall must be so shaped as to fit the contour of the welded parts on the wall.
In Canadian patent No. 933,101 issued September 4, 1973 to Illinois Tool Works Inc. there is disclosed a handle member which forms an integral part of a plastic sleeve that is interlocked with the peripherally seamed end of the can assembly. The sleeve includes a semi-cylindrical slit to form a semi-cylindrical strap which may be stretched to position above the can to serve as the handle member when used. One disadvantage of such a system is that the weight of the can combined with the effect of having a slit in the sleeve often results in the tearing off of the handle portion from the sleeve.
Other types of plastic bands presently used on the marXet consist of two piece elements which are interconnected together to form a handle member. `-OBJECTS AND STATEMENT OF THE INVENTION
It is an object of this invention to provide for use in combination with a container, a unitary plastic handle which 6'71 provides a tight engagement against the body wall of the container. This is achieved by providing the band portion of the handle with a configuration that includes a concave inner face which, when forced flat against the body wall of S the container under stretched condition, causes one peripheral edge thereof to tightly engage beneath the rim of the can.
The present invention therefore pertains to a handle for use in combination with a container having a body wall and a rim extending along one peripheral end thereof, which comprises: an endless band of thermoplastic material which is resiliently stretchable so that, when inserted on the container, the band is in a stretched condition on and in tight engagement with the body wall; and a bail molded integrally with the band to form a unitary structure, the bail including a pair of arm portions joined respectively to generally diametrically opposite portions of the band; the band has a circumferentially constant cross-section with an inner face and upper and lower peripheral edges; the inner face is concave when in a non-stretched condition, the concavity causing one of the peripheral edges in tight engagement underneath the rim when the band is in the stretched condition and flat against the body wall.
In one form of the invention, the peripheral edge, or both, has a shape complementary to that of the rim to facilitate the pouring of the material inside the container.
In another form of the invention, the peripheral edge, or both, has a pointed extremity.
In another form of the invention, the peripheral edge, or both, is provided with a series of circumferentially spaced notches for ease of band expansion and for providing sliding-off resistance to the band.

DESCRIPTION OF PREFERRED E~OD_MENT
Referring to Fig. 1 there is shown a plastic handle, generally denoted 10, mounted to a metallic container generally denoted 12.
The container 12 includes a cylindrical body wall 14 and a lid or cover 16. As shown in Fig. 3, the upper peripheral ~. ~ r~ 6 ~7 ~L
edge of the body wall projects outwardly to form a peripheral rim 18 spaced outwardly from the adjacent surface of the body wall. A similar peripheral rim 20 is, in most cases, provided at the lower peripheral edge of the body wall. Some containers may be constructed without a lower peripheral edge.
The handle 10 is formed of a thermoplastic material that is resilient, flexible and elastic. The handle consists of two portions: an endless band 22 and a bail 24 which are formed together as a unitary assembly by means of a plastic forming operation, such as by injection moulding. Although polyethylene is a preferred example of a suitable plastic material which is resistant to tearing, other functionally similar materials could be used satisfactorily for the handle 10.
The material of the handle must be resiliently stretchable for allowing the passage of its band portion 22 over the peripheral rim 18 or 20 of the container.
Bail 24 includes two arm sections 26 and 28; as shown in Fig. 6, these arm portions preferably have an H-shaped cross-section for most of its length. At an intermediate point of the bail, a notch 30 on the inner wall provides a seating arrangement for a support from which the container may be suspended. The arm sections 26,28 are connected to generally diametrically opposite portions of the band by means of flat connection portions 3Z,34, respectively. These portions are flat and extend in a plane parallel to the plane of the endless band 22. The cross-section of these portions 32,34 are reduced compared to the cross-section of the arm sections 26,28 to provide a hinged action when the bail is rotated relative to the band.
Referring to Fig. 2, the band 22 has an inner concave surface 36 and upper and lower peripheral edges 38 and 40.
In the embodiment described, the upper edge 38 is slightly curved to fit the shape of the peripheral rim 18 of the container. The lower edge 40 is similarly shaped so that proper positioning of the band during insertion assembly of the band on a container is eliminated.
To insert the handle on the container, band 22 is radially expanded by a stretching device, such as described in applicant Canadian copending application Serial No. 347,360 filed March 10, 1980. Once the band is positioned on the metallic container, it takes the position shown in Fig. 3 where the concave inner face becomes flat since it remains on the body wall of the container under stretched condition. The concavity of the endless band forces the upper extremity 38 in tight engagement beneath the peripheral rim 18 of the container.
Fig. 4 shows another band 42 which also includes a concave inner face 44 but with pointed upper and lower extremities 46,48. In this form of the invention, the pointed extremity is tightly engaged in the corner formed by the peripheral rim 18 of the container and the body wall 14.
Fig. 5 shows a handle 10' similarly constructed to the handle 10 shown in Fig. 1. However, in this form of the invention, the band portion 22' of the handle is provided with a series of circumferentially spaced notches 50 which have a dual function: it serves to ease the expansion of the endless band during its insertion of the metallic container;
secondly, it provides sliding resistance should the endless band become partially removed from the peripheral rim.
DESCRIPTION OF PREFERRED E~OD_MENT
Referring to Fig. 1 there is shown a plastic handle, generally denoted 10, mounted to a metallic container generally denoted 12.
The container 12 includes a cylindrical body wall 14 and a lid or cover 16. As shown in Fig. 3, the upper peripheral ~. ~ r~ 6 ~7 ~L
edge of the body wall projects outwardly to form a peripheral rim 18 spaced outwardly from the adjacent surface of the body wall. A similar peripheral rim 20 is, in most cases, provided at the lower peripheral edge of the body wall. Some containers may be constructed without a lower peripheral edge.
The handle 10 is formed of a thermoplastic material that is resilient, flexible and elastic. The handle consists of two portions: an endless band 22 and a bail 24 which are formed together as a unitary assembly by means of a plastic forming operation, such as by injection moulding. Although polyethylene is a preferred example of a suitable plastic material which is resistant to tearing, other functionally similar materials could be used satisfactorily for the handle 10.
The material of the handle must be resiliently stretchable for allowing the passage of its band portion 22 over the peripheral rim 18 or 20 of the container.
Bail 24 includes two arm sections 26 and 28; as shown in Fig. 6, these arm portions preferably have an H-shaped cross-section for most of its length. At an intermediate point of the bail, a notch 30 on the inner wall provides a seating arrangement for a support from which the container may be suspended. The arm sections 26,28 are connected to generally diametrically opposite portions of the band by means of flat connection portions 3Z,34, respectively. These portions are flat and extend in a plane parallel to the plane of the endless band 22. The cross-section of these portions 32,34 are reduced compared to the cross-section of the arm sections 26,28 to provide a hinged action when the bail is rotated relative to the band.
Referring to Fig. 2, the band 22 has an inner concave surface 36 and upper and lower peripheral edges 38 and 40.
In the embodiment described, the upper edge 38 is slightly curved to fit the shape of the peripheral rim 18 of the container. The lower edge 40 is similarly shaped so that proper positioning of the band during insertion assembly of the band on a container is eliminated.
To insert the handle on the container, band 22 is radially expanded by a stretching device, such as described in applicant Canadian copending application Serial No. 347,360 filed March 10, 1980. Once the band is positioned on the metallic container, it takes the position shown in Fig. 3 where the concave inner face becomes flat since it remains on the body wall of the container under stretched condition. The concavity of the endless band forces the upper extremity 38 in tight engagement beneath the peripheral rim 18 of the container.
Fig. 4 shows another band 42 which also includes a concave inner face 44 but with pointed upper and lower extremities 46,48. In this form of the invention, the pointed extremity is tightly engaged in the corner formed by the peripheral rim 18 of the container and the body wall 14.
Fig. 5 shows a handle 10' similarly constructed to the handle 10 shown in Fig. 1. However, in this form of the invention, the band portion 22' of the handle is provided with a series of circumferentially spaced notches 50 which have a dual function: it serves to ease the expansion of the endless band during its insertion of the metallic container;
secondly, it provides sliding resistance should the endless band become partially removed from the peripheral rim.
