Description
Background of the Invention
The present invention relates to containers with covers such as those manufactured in great numbers for the purpose of packaging food, paint and the like. The container and cover are usually injection molded from plastic, such as polyethylene, polypropylene and the like, the cover being typically manufactured from a softer plastic than the container.
Such containers have to be properly closable and relatively easy to open.
It is also important that such container have an attractive appearance as this enhances the marketability of the contents.
Summary of the Invention
The present invention relates to a container provided with hand-grips which lie comfortably in the hand and do not disturb the compact appearance of the container. The container is nestable and stackable with its cover on. The hand-grips are formed on a skirt surrounding the open end of the container.
Another aspect of the present invention relates to the printing of text on such containers. The handle is disposed so that it does not block the outer surface of the container during printing thereof. Ordinarily, handles are attached to containers after the containers are printed, which usually takes place manually and also necessitates extra storage and transport.
If the handle is embodied in plastic and rests on stop elements or it is virtually invisible, thus not disturbing the compact appearance of the container.
A further aspect of the present invention relates to sealing of covers on such containers so as to prevent poison, contraband and the like, from being added to the contents of the container by unauthorized persons.
The present invention further provides a novel sealing element for accomplishing the sealing of the cover to the container.
Brief Description of the Drawings
Further details, features and advantages will become apparent in the light of a description of preferred embodiments and embodiments of the present invention with reference to the annexed drawings, wherein:
FIG. 1 shows a perspective view of a first preferred embodiment of the present invention;
FIG. 2 shows a partly cut away perspective view of the preferred embodiment of FIG. 1;
FIG. 3 shows a perspective view of a sealing element according to the present invention;
FIG. 4 is a perspective view of another preferred embodiment of the present invention; and
FIG. 5 is a perspective view of the holder of FIG. 4 with a freely accessible top opening.
Detailed Description of the Invention
In the present invention a distinction can be made between containers having a capacity in the range of about 0.4-14 liters and larger holders, because customers for these two types of containers are wholly distinct. In addition, the smaller capacity holders are generally supplied without handles.
The container 1 (FIG. 1) of for instance, 5 liter capacity is provided with a cover 2 in which an upstanding disc 3 is arranged for the purpose of stacking with a corresponding base (not shown) of another container.
As can also be seen in FIG. 2, the cover 2 is provided with a lip 2a, including outer surface 2b and inner surface 2c, and a groove 4 which grips over a top edge 5 of the container 1. In addition, a downward hanging skirt 7 is arranged on the side wall 6 of container 1. Around the skirt 7 is arranged a recess 8 for easy bending of the cover during opening of the container.
Arranged on the skirt 7 are one or more hand-grips 9. The outer surface 10 of the hand-grips 9 stands out slightly more than the skirt 8, so that a user can place his hand thereunder while the angle is not so large that the compact appearance of the outer wall of the container is disturbed. In addition, the hand-grip supports the skirt 7 by means of the side walls 11. The hand-grip 9 further forms a stop for the nesting of such containers, while a number of nested containers or buckets can be carried on the hand-grip. Preferably, an eye 12 is arranged above the middle of the hand-grip 9, wherein a second handle can be simply placed.
The cover 2 is preferably sealed onto the container 1 using a plurality of sealing elements 20 (FIGS. 1, 2 and 3), the number whereof a number, depending on the size of the container. In the embodiment shown three sealing elements are arranged at regular intervals around the cover.
As can be seen in FIGS. 2 and 3, the sealing elements 20 can be attached to the container and the cover in a simple operation. As shown in FIG. 3, the sealing elements 20 consist of two pieces: an upper jaw member 22 with a downwardly extending arm 23; and a hook 21 with two upwardly extending arms 26, 27.
After a hook 21 has been hooked under the skirt 7 of the container jaw member 22 is pushed over the top side of the groove 4 of the cover. Arm 23 is provided with upward oriented teeth 24. As can be seen in FIG. 2, the arm 23 is received between a bridge element 25 which extends transversely of the arm 23 and which is fixed between two upwardly directed arms 26 and 27 and a lip 28 which grips onto the teeth 24.
As will be apparent, such a sealing element can only be removed through forcing, that is breaking, thereof.
Depending on the stiffness of the arm 23 and the lip 28, the sealing number can be provided with a second bridge element parallel to the bridge element 25 but arranged at some interval above or below it to further secure arm 23 in place.
The embodiment shown in FIGS. 4 and 5 relates to a container with a capacity of more than 15 liters on which a plastic handle 31 is arranged using the eyes above the hand-grips 39, while the skirt 37 is provided with one or more protruding stop elements 38. As the handle 31 has an only slightly greater length than half the outer periphery of the opening 33 of the container it will rest in a downward pivoted position (FIG. 5) on one or more stop elements such that the handle does not form an obstacle to the printing of text on the outer wall 35 of container 30.
Furthermore, the handle 31, in its downward pivoted position does not disturb the appearance of container 30, for instance when the hand-grips are used to carry this container 30.
Claims
I claim:
