Abstract

Frame (1) made of plastic with a base body (2) for attachment in the edge region of an opening (15) of a container (10), in particular a box for storing paints, varnishes or the like, characterized by a bracket (3), the film hinges (4a, 4b) is connected to the base body (2).

Description

The The invention relates to a frame made of plastic with a base body for attachment in the edge region of an opening of a container, especially a can for storing paints, varnishes or like.

Such a framework is out of the DE 10 2007 007 171 A1 known. The peripheral frame is there over the side wall of the container, z. B. a paint can, inwardly and can be snapped onto the edge region of the container opening. The frame is intended to prevent the liquid filling material in the container from readily escaping through the container opening during the movement of the container. Also, the frame allows for easy stripping of paint or varnish from a tool, e.g. B. from a brush. To close the container, a lid on the inside of the frame can be snapped or clamped.

Of the Invention is based on the object, a frame of the above so-called type such that with this framework provided container easier and therefore cheaper is to produce.

This object is achieved by a frame in which a strap is connected via film hinges to the base body. The production of such a frame with integrated bracket is particularly easy and can be produced in injection molding with a shot. The attachment of the bracket to the frame has the advantage that the container can be filled or labeled in any orientation. A connection of the bracket on the side wall, as z. B. in the aforementioned DE 10 2007 007 171 A1 is described in this regard is unfavorable, since this type of connection makes an orientation of the container during labeling mandatory.

For the connection of the bracket to the usually profiled There are several possibilities. So can the profiled Basic body of the frame for example a (circumferential) Have sink on which the film hinges for connecting the bracket are attached, with the connection of the film hinges longitudinally and / or can run transversely to the sink. By providing the film hinges in the valley, the bracket z. B. when stacking several Container on each other or when welding the Frame on a side wall of the container in the sink dive. Also, the stirrup in the sink is against possible Damage protected from the outside.

Of the Alternatively, the bracket can also be defined by a border area circumferential, web-shaped edge of the body be formed by one along the circumferential direction of the edge extending cutout, z. B. a gap, separated from the body is. The web-shaped circumferential edge can z. B. at the Be mounted inside or outside of the frame. A web-shaped outer edge may, for. B. when stacking several containers on top of each other the bottom area of a enclose the frame resting on the frame and so a lateral fixation of the container when stacking serve.

Of the Bracket can in its normal position, d. H. in those Position the strap without a deflection by one Operator, at a non-zero angle of attack be aligned to the body, so that the operator Handle can be easier. When attaching the bracket to the Outside edge of the frame, but it is cheap, the temple align in its basic position parallel to the main body, because in such Anbringings the hanger in a horizontal Basic position can be detected easily.

In an alternative embodiment, the film hinges on the outer edge attached to the base and the bracket is over the body over to the outside. Also In this case, the bracket can be parallel in its basic position aligned with the plane of the annular body be. It is of course also in this way the connection possible, the bracket in its normal position Align at an angle to the body.

For have the angle of the bracket to the body Angular values between 5 ° and 40 °, preferably between 10 ° and 30 ° proved to be favorable. The choice of an angle of attack in this angular range allows an easy gripping of the strap by an operator. Of the Anstellwinkel of the bracket can in this case via a suitable shaping of the hinges or the connection of the bracket be specified on the film hinges.

Especially when using a two-component injection molding process in the manufacture of the frame, the bracket can and the main body also made of different plastic materials consist. In this case, the strap and the body different properties z. In Reference to their color, strength, etc. have. It goes without saying that care should be taken that two compatible plastic materials be chosen, d. H. two materials that are connected to one another Connect the flow front in the area of the film hinges can.

Also, the frame may have a tamper-evident, which is broken when moving the bracket from its normal position. The tamper-evident can in particular by a Bridge be formed between the bracket and body. It is understood that it is favorable for the tamper-evident, if the distance between the bracket and body in the basic position of the bracket is small, ie the tamper-evident can be particularly easily mounted in cases where the angle of attack is small. The latter is z. B. the case when the bracket is aligned parallel to the plane of the body.

Of the The frame described above can in particular by injection molding be prepared, the entire frame when using only one plastic material can be made by a single shot. The production the frame made of plastic also allows in particular, the bracket with a desired geometry or shape, z. B. with a profiling, equip.

At The frame profile may additionally or alternatively to the bracket further form elements are formed, for example Cross ribs for reinforcement at the bottom and / or at the Top of the frame. However, it has been shown that for the Storage of paints or paints the use of a ribless Frame contour is usually cheaper because z. B. when installing transverse ribs along the top of the frame Paint or varnish in the spaces between the ribs collect and difficult to remove.

One Another aspect of the invention relates to a container, especially a box for storing paints, inks or like, with a bottom, a circumferential side wall and a the bottom opposite opening, the one Frame having formed as described above. The frame is in the area of the opening along the container circumference attached to the side wall. By integrating the bracket in The frame may be attached to the attachment of the bracket to the revolving Side wall of the container can be dispensed with. This is special favorable for containers with round cross-section, since the round container in this case when labeling does not have to be oriented.

Of the Frame can with the circumferential side wall of the container be connected in different ways. In addition to an irreversible, cohesive connection, z. B. by welding, bonding or the like is also a non-positive and / or positive Connection z. B. by bouncing (friction), screwing, latching or snapping the frame to the side wall possible. A cohesive connection of the frame with the side wall, especially by welding, has proved to be particularly favorable proved.

Around a filling of the container on conventional, for filling sheet metal containers designed filling and labeling equipment, can be in the area of the ground and on the outer edge of the frame be formed in each case a circumferential bead, the over the side wall protrudes outwards. While for sheet metal containers flanged edges one necessary consequence of the manufacturing process are the items of the container (bottom, side wall, annular Frame) are used in plastic containers No crimping edges required due to the production. However, the crimping edges allow it, the set-up times and setup costs for retrofitting a Filling plant of tin containers on plastic containers (and vice versa) to minimize.

Of the Border edge in the region of the bottom and / or the beaded edge in the area of the opening can be bar-shaped be educated. This is convenient to the containers to stack better on each other. In particular, can Here, the inside of the web-shaped Bördelrands projecting further outwards in the area of the opening as the outside of the crimping rim in the area the floor (or vice versa) to a lateral fixation of several to reach each other stacked container.

To secure the transport, the crimping edge may have knobs in the region of the opening and / or the crimping edge in the region of the bottom. If adjacently arranged containers are brought into abutment with one another, the nubs of the containers engage in one another and fix their relative position to one another. By the nubs thus a lateral securing of several containers can be carried out relative to each other. For details in connection with the design of the studs is on the DE 20 2009 001 356 U1 referred to the applicant.

Of the Container can, as usual with cans, a side wall having a cylindrical basic shape, d. H. the cross-sectional area the container remains over its entire height constant. This is u. a. for labeling the container Cheap. It is understood that containers with cylindrical Basic shape may have different cross-sectional geometries. In addition to a circle or an oval as a cross-sectional shape can also polygonal, in particular square or rectangular cross-sectional shapes used become. The container may also be one of a cylindrical Basic form deviating, z. B. have conical shape.

The container may in particular also have a lid for closing the opening, which has a side edge for sealing connection with an inner edge of the frame. The lid can be attached to the frame, for example by latching or by bouncing. Here in the inner edge of the frame may be formed by an axial web which seals with the outside of the side edge of the lid.

Of the Lid may also project beyond the inner edge of the frame Have projection on which preferably a stiffener, in particular is provided in the form of transverse ribs. Typically remains with the lid on between the projection and a support surface on the frame, a gap into which a tool, for. B. a Screwdriver, can be inserted to the lid to lift off the container. It is understood that to take off the lid does not necessarily have a projection must be provided. Also can on the lid and / or on the frame an opening aid, z. B. in the form of a groove, for engagement with a tool be provided. It is understood that the lid and / or the Frame may also be provided with a tamper-evident closure which enables an open and subsequently recognize again closed container. It is further understood that the lid is not necessary must consist of a plastic material and z. B. also made of sheet metal, Glass, etc. can be made.

Of the Containers or parts of the container can z. B. made of polyethylene or polypropylene. It understands itself that different parts of the container from different Plastic materials can exist. So z. B. the frame or the lid made of a different plastic as the main body (side wall and bottom) of the container. Typically, the container described herein will be described produced by injection molding. It goes without saying that especially for small-sized containers individual Parts of the container, eg. B. the main body (side wall and bottom) in other ways, for. B. by deep drawing can be.

6a , b are schematic representations of an embodiment of the container according to the invention, on which a frame from the in 1a , b type shown attached, as well as

7 a longitudinal section through two stacked containers of in 6a , b type shown.

1a , b show a frame 1 , the an annular, profiled basic body 2 has, on which a bracket 3 over two hinges 4a . 4b is connected. The film hinges 4a . 4b are here in a sink 5 attached so that the hanger 3 into the valley 5 can immerse and is protected in this way from damage.

As in 1b It can be seen, is the connection of the bracket 3 to the film hinges 4a . 4b designed so that the hanger 3 in its normal position at an angle α of about 5 ° to that through the body 2 aligned level. The orientation of the temple 3 at an angle of attack allows easy gripping of the bracket by an operator. From the basic position of the bracket can be spent in a substantially vertical position, as in 1b indicated by dashed lines. Of course, the strap can 3 in its basic position also at a different angle α with respect to the body 2 be aligned, in particular angle of attack α between about 5 ° and about 40 ° have proven to be particularly favorable.

For the connection of the bracket 3 to the body 2 or to the sink 5 There are different possibilities. For example, the film hinges 4a . 4b of the temple 3 as in 2a , b is shown longitudinally at the sink 5 be connected. Alternatively, it is also possible, the film hinges 4a . 4b across the valley 5 to bind, as in 3a , b is shown. In any case, between the hanger 3 and the body 2 a tamper evidence z. B. in the form of a (not shown) web are provided.

4a , b show an alternative embodiment of the frame 1 in which the hanger 3 in a circumferential, web-shaped outer edge 6 of the basic body 2 is integrated. The coat hanger 3 is in this case by an edge region of the web-shaped edge 6 formed from the main body 2 through an encircling, semicircular cutout (slot) 7 is disconnected. The film hinges 4a . 4b are here at the transition between the bracket 3 forming edge region and the part of the web-shaped edge 6 attached, which is not provided with a cutout.

At the in 4a , B embodiment shown is the edge forming the bracket 3 parallel to the plane of the main body 2 aligned. This allows a short jetty 8th between the border area 3 and the body 2 to provide, which serves as a predetermined breaking point and forms a tamper evidence. Becomes the easily accessible outside area 3 grabbed by an operator and lifted up, breaks the bridge 8th and allows lifting the bar 3 to recognize. Of course, also in the in 4a , frame shown 1 by suitable design of the film hinges 4a . 4b a non-zero angle of attack of the edge area 3 be set. Also, the bracket may optionally in an analogous manner to a web-shaped, more inner edge of the frame 1 be attached.

In 5a , b is another embodiment of the frame 1 shown in which the bracket 3 over the circumference of the annular body 2 survives. The film hinges 4a . 4b are in this case on the outer circumference of the body 2 attached and stand over the main body 2 over to the temple 3 spaced from the main body 2 to be able to connect. At the in 5a , b shown embodiment is the bracket 3 as well as in the 4a , B embodiment shown parallel to the plane of the body 2 aligned and one between basic body 2 and hangers 3 arranged bridge 8th serves as tamper evidence. Of course, also at the in 5a b embodiment shown by suitable shaping of the film hinges 4a . 4b a non-zero angle of attack of the bracket 3 be set.

It is understood that the hanger 3 unlike the above does not necessarily have to be smooth. For example, the plastic strap 3 with a profiling, z. B. with spikes, waves or flags provided. In particular, when using a two-component injection molding process, it is also possible for the main body 2 and the temple 3 to choose different plastic materials that extend along a flowing edge in the area of the film hinges 4a . 4b unite. For example, this can be a different color design of the bracket 3 in comparison to the main body 2 or it can be materials with different stiffness for hangers 3 and basic body 2 to get voted. In the event that the frame 1 is to be made of a single plastic material, this can be produced in an injection molding with a single shot.

The frame described above 1 Can on a container 10 be attached in plastic, as in 6a , b is shown. The container 10 can z. B. for storage of paints, colors or the like and has a bottom 11 , a circumferential side wall 12 and one to the ground 11 opposite opening on in the in 6a , b shown illustration of a lid 13 is closed.

At the top of the container 10 as well as at the bottom of the container 10 is each a circumferential, outward over the side wall 12 protruding edge 14a . 14b intended. The edges 14a . 14b Here are the beaded edges of a sheet metal container modeled and are therefore hereinafter referred to by the term "Bördelränder". The crimp edges 14a . 14b of the container 10 enable it to be filled on conventional filling machines designed for filling metal containers.

7 shows the container 10 without the lid, leaving the floor 2 opposite opening 15 can be seen. In the area of the opening 15 is on the sidewall 12 the profiled frame 1 in the embodiment of 1a , b attached. On the outside of the frame 1 is the upper flange 14a educated. The frame 1 is with the sidewall 12 connected in the present example by welding, but it is understood that the connection between the frame 1 and the side wall 12 can also be done in other ways, for. B. via a positive connection and / or a frictional connection, ie the frame 1 in particular, via a releasable (snap or latching) connection to the container 10 be attached.

As in 7 can also be seen, are the upper and the lower bead 14a . 14b formed web-shaped, wherein the inside of the web-shaped upper flange 14a further protrudes outwardly than the outside of the web-shaped lower flange 14b , When stacking another container 10 ' on the container 10 serves the web-shaped lower flange 14b ' the further container 10 ' as Stehrand and lies on a circumferential radial bearing surface 16 of the frame 1 of the lower container 10 on. The upper web-shaped border 14a of the container 10 encloses the lower web-shaped bead 14b the further container 10 ' with little play, leaving the two containers 10 . 10 ' be fixed in the stacking in their relative position to each other.

Additionally, at the bead edges 14a . 14b (not shown) nubs are provided, which over the respective bead 14a . 14b survive outside. Be adjacent containers arranged with each other in Appendix brought, grab the nubs on the containers into each other and fix their relative position. By the nubs thus a lateral securing of several juxtaposed containers can be carried out relative to each other to fix them during transport suitable, as in the DE 20 2009 001 356 U1 the applicant is shown in detail.

As in 7 Shown is the hanger 3 from the home position down to a substantially horizontal position parallel to the plane of the annular frame 1 be spent. When stacking the hanger 3 in this case of an annular, raised portion of the soil 11 ' the further container 10 ' held down. Also, the strap can 3 Be moved further down the horizontal position to the hanger 3 in the between the bearing surface 8th and a support surface 17 formed valley 5 of the frame 1 take.

For fixing the lid 13 indicates the frame 1 an inner web extending in the axial direction 18 on, with a (not shown) side wall of the lid 13 sealing can be brought into abutment, so that the lid 13 the opening 15 sealing closes.

The lid 13 has at its outer edge a in 6a shown projection 19 on top of the axial web 18 of the frame 1 overlaps and the lid 13 via a press fit on the frame 1 fixed. The one on the lid 13 educated edge 19 can a stiffening z. B. in the form of transverse ribs. This is beneficial when levering the lid 13 a tool, eg. As a screwdriver, in between the projection 19 of the lid 13 and the support surface 17 of the frame 1 formed intermediate space is introduced to the lid 13 from the frame 1 withdraw.

It It is understood that the frame with integrated bracket does not work must necessarily be configured annular. Much more the frame can be adapted to the respective container geometry have adapted shape and z. B. be configured oval or polygonal. Also, if necessary, additional mold elements, for example in the form of reinforcing ribs on the frame be provided. Of course, the frame with integrated bracket also attached to containers are not cylindrical, over the height of the container have constant cross-section, for example on conical containers. In any case, the Production costs for the container by the the integration of the bracket into the frame can be lowered.
