Description
lZ27~47 The invention relates to a container of thermoplastic material, and in particular to such a container of small size light weight and low cost, such as is used for cosmetics and the like, having a body portion and a lid which are hinged together along one edge.
Hinged type plastic containers are used for a wide range of products, cosmetics being merely one of such products. In such containers there are various desirable characteristics. It is desirable that the hinge shall permit the lid to be raised and lowered readily. The hinge should preferably provide a positive stop, limiting the angle to which it can be swung open. The hinge will preferably incur-prorate some form of frictional means, to provide a positive open position, so that -the container may be used with the lid open, without the lid accidentally closing.
In the particular case of a cosmetics con-trainer, such as a powder compact, the lid usually contains a mirror. It is therefore in this case highly desirable that the lid when open shall remain firmly in position, so that the mirror does not constantly move about.
In the past, -there have been various forms of compact which met these requirements. However, since -the design of these compacts is slim, so as to fit in the pockets, or a personal carrying case such as a handbag, the physical size of -the hinge components was small. The manufacture and the assembly ~XZ7~47 of such a plastic article wherein the hinge combo-newts are relatively small poses certain problems.
It may be difficult to remove the finished article from the mold without breakage. It may be difficult to assemble the finished article without breakage.
In order to overcome the problem of break-age, most of such smaller sized plastic containers have been manufactured of relatively expensive raw materials. Clearly, it is desirable if such con-trainers can be manufactured of low cost materials such as styrenes However, in the past styrenes has been regarded as unsuitable for containers of this type, due to its brittle nature.
Clearly, it is desirable that such con-trainers shall be made of the lowest cost material, provided the necessary characteristics of durability and function can still be maintained.
BRIEF SUMMARY Of THE INVENTION
The invention therefore seeks to overcome the foregoing disadvantages, and comprises a con-trainer of thermoplastic material comprising, a bottom portion, a lid portion adapted to mate with such bottom portion, and hinge means connecting said lid portion and said bottom portion, said hinge means comprising a first hinge member on one of said bottom and lit portions and a second hinge member on the other of said bottom and lid portions and wherein said first hinge member comprises a generally cylindrical hinge pin portion, and means supporting said hinge pin portion, and wherein said

DESCRIPTION OF A SPECIFIC EMBO IMENq' Referring first of all to Figure 1, it will be seen that the invention is illustrated here in connection with a relatively slim flat wallet shaped container 10. Such a container 10 may be typically used for the sale of cosmetics such as powder, in the form of a powder compact. However, such a container is merely one illustration of a form of the invention, and it is not -to be taken as restrictive of the scope of the invention as such.
I
The container as illustrated has a bottom portion 12 and a lid portion 14, which generally speaking are of the same shape, and they fit together to enclose a product or some material contained therein.
In the example of a powder compact, such a container will typically have a small mirror mounted on the inside of the lid, and powder will be supported in a suitable receptacle in the bottom portion. Such mirror and recent-ado are omitted from this disclosure for the sake of clarity. It will however be appreciated that they are not in any way limiting of the scope of the invention, and are in any event well known in the art.
The lid and bottom are hinged by hinges indicated generally as 16 which will be described below. The lid and bottom may also be held closed by means of some form of fastening device (not shown) which may vary widely, and which is in any event well known in the art and forms no part of this invention.
It will be appreciated that in many instances, not merely in the case of a powder compact as illustrated, it is desirable that the container may be used repeatedly over an extended period of time, by opening and closing the lid. When in use, the lid will preferably be held at a pro-determined open angle, convenient for use of the mirror contained within the lid.
AYE
If the lid is loose on its hinge, then it becomes more awkward to use -the mirror.
Accordingly, it is considered desirable that the hinge shall in some way contain some form of restraint or partial locking mechanism so that the lid is held in the open position during use , and yet it may readily be swung for closing .
It also evident that both in the case of a powder compact and in many other instances it is desirable that the product shall be made as far as possible economically, by high speed injection molding techniques, using low cost therm plastics materials.
Due to the size of the container in this case, it will be readily apparent that the hinge component will be of small dimensions.
Molding of small plastic features in this way is crown -to present problems. In particular, when -the article is removed from the mold, after a relatively brief molding cycle, i-t is quite common for small plastic features -to be brazen off. This leads -to a high ate of rejects.
I-t is also known that during assembly of small plastic components or features of this kind, that they are also liable to break, again causing rejects during assembly.
For all of these reasons it has in the past been considered necessary -that articles of this kind should be manufactured of relatively high grade ~X27~47 plastics material, having a lower rate of fracture. This has substantially increased the cost of such containers.
In accordance with the invention, a container is provided in which an improved form of hinge provides a greater degree of effectiveness in use and also reduces the likelihood of breakage during molding and during assembly operations. The invention thereby permits the molding of such containers out of a lower cost material typically a styrenes type material, so that the entire container can -thus be sold at a lower price.
Referring now to Figures 2-6, the invention is illustrated in more detail.
As best shown in Figure 2, a portion of the container bottom 12 and a portion of -the container lid 14 are shown, -together with a single hinge indicated generally as 16.
As mentioned above, this is merely illustrative of the invention. As shown in Figure AL, there are in fact two such hinges on -the present embodiment. There could of course be a single hinge, or there could be three or more as desired.
The hinge 16 will be seen to comprise two components namely a hinge pin component indicated as 18 and a hinge arm component indicated as 20. As illustrated, the hinge pin component 18 is shown extending from -the bottom portion of the container and the hinge arm component is shown extending from the lid portion of the container. It will however be appreciated that this is merely one way of using the invention. The invention could equally well be used -the opposite way around if desired.
The hinge pin component 18 will be seen to comprise a generally cylindrical elongated hinge pin member 22, integrally formed together with a pair of pin flange members 24 integrally rooted on the rear wall 26 of the container bottom portion 12.
The pin portion 22 will thus be seen to be spaced to predetermined distance behind the rear wall, supported at each end. As mentioned, there are two such hinge pins 22, spaced apart from one another along the back wall of the con-trainer bottom , equidistant from each end.
The hinge arm portion 18 comprises an inner hinge arm 30, and an outer hinge arm 32. Arm 32 is formed on wall 34 of Jig 14.
Arm 30 is formed on inner wall 36, formed inside lid 14.
Arm portion 30 is separated from wall 36, by notches 37, which receive flanges 24.
Arms 30 and 32 are of the same length as pin 22, so as to fit between flanges 24.
Both the inner and outer hinge arms extend ~X27~47 beyond the extent of the rear wall and the inner partition walls respectively, and define free edges.
Along the inner portions of the free edges of the arms 30 and 32, there are formed oppositely directed lip portions 38 and 40.
The two lip portions define a narrow opening, which is narrower than the spacing between the two hinge arms . They are thus adapted -to make a snap fit around the hinge pin, and hold it securely held between -the two hinge arms.
In order to limit the depth to which the hinge pin can enter between the two hinge arms, a frictional s-top member 42 is formed, which is rooted between the inner and outer hinge arms, extending downwardly from a portion of the lid 14, between the inner end wall and -the rear wall.
The stop member is generally wedge shaped in cross section and in fact is separated from the two hinge arms for reasons to be described below.
Its free end is intended to bear on the hinge pin when -the hinge pin is sea-ted between the two arms, and -to create a frictional stop.
It will of course be apparent that in -this embodiment of the invention there are two pairs of such hinge arms , one pair for each such hinge pin.
At this point, it should also be noted that the outer hinge arm lo somewhat longer than the ~2271~7 inner hinge arm, and is curved so that it extends around and partially under its hinge pin.
It is also of generally progressively tapering shape in section.
This feature provides the advantage that when the hinge is rotated and the lid is opened, the curved portion of the outer hinge arm will fit between the hinge pin and the rear wall of the bottom portion 12, and will eventually bind and cause a positive stop limiting further opening movement. At the same time, in this limiting position, the rear wall will partially embrace the inside of the hinge pin, that is to say the portion of the hinge pin adjacent the back wall of the bottom portion. This will -then reduce the tendency of the -two hinge arms to open up when the lid is fully opened, and will prevent the hinge arms from falling off -the hinge pin due to opening of -the lid.
Slaving described what is believed to be -the best mode by which the invention may be performed, it will be seen that the invention may be particularly defined as follows:
A container of thermoplastic material comprising a bottom portion, a lid portion adapted to mate with such bottom portion, hinge means connecting said lid portion and said bottom portion, said hinge means comprising, a first hinge member on one of said bottom and lid members, a second hinge member on the other of said bottom and lid members, and wherein said first hinge member comprises, a generally cylindrical hinge pin portion, and means supporting said hinge pin portion, and wherein said second hinge member comprises inner and outer hinge arm portions, said arm portions being ', spaced apart from one another, and defining a generally regular channel shaped space there between adapted to fit around and receive said hinge pin portion, lip portions on the free edges of said hinge arm portions defining a restricted spacing th~rebetween less than the spacing between said arm portions, and adapted to make a snap fit around said hinge pin portion, at least one of said hinge arms being resiliently flexible relative to the other said hinge arms to open up for receipt of said hinge pin there between, and, a pun bearing member located between said arm portions, and adapted to engage said hinge pin portion.
The foregoing is a description of a preferred embodiment of the invention which is given here by way of example only. The invention is not to be -taken as limited to any of the specific features as described, but comprehends all such variations thereof as come within the scope of the appended claims.
