Description

Movement element for can lids

The present invention relates to a moving member for a can end.

The invention further relates to a can end, a can and a method, all according to the preambles of the independent claims.

Technological background

Cans such as patent lid cans or press-lid cans are known. These are manufactured as tin cans, which are mostly made of tinplate, i.e. tinned sheet steel. In addition to good tightness values, these tin cans are also easy to stack and offer reliable protection for the contents, e.g. for paints, varnishes, lubricants, glazes, oils, pastes, waxes, etc.

The patented lid cans are also known as ring cans or paint cans, are made of bare tinplate with a seamed ring and have a push-in lid. The ring and bottom fold are sealed with rubber in the fold. The cans close tightly with the push-in lid. The lid is pressed into the ring and thus closes the can securely and reliably. The can can be opened and sealed again as often as you like. The cover is levered open with a suitable tool. Ring tins are very suitable for retained samples. Patent lid cans are proven and safe packaging for varnishes, paints, wood preservatives, solvent-based fillings and for other chemical-technical products as well as for certain foods. The boxes can be designed without internal coating. On the other hand, for water-based contents, such as acrylic paints, there are so-called acrylic paint ring tins with a special internal coating and a powder-coated weld seam to protect against corrosion. Patent lid cans are available in various designs and sizes, for example up to 3000 ml. A can with a nominal volume of 100 ml, for example, has a diameter of 56 mm and a height of approx. 55 mm.

Press-in lid cans, also called outer roller cans or plate lid cans, can be emptied very easily because they have no ring or rim at the opening. The edge of the fuselage is bordered on the outside. The maximum opening corresponds to the diameter and is therefore ideal for viscous, solid and pasty filling goods. There are also a wide variety of designs and sizes for tinplate cans with push-in lids, which are extremely easy to empty. A can with a nominal volume of 1000 ml, for example, has a diameter of 99 mm and a height of approx. 150 mm.

Tinplate is thin-rolled steel with a layer of tin to prevent corrosion. The tinplate is versatile, malleable, light, robust, stable, resilient and dense. Steel has no expiry date and can be recycled multiple times without any loss of quality. The mechanical resilience is just one of the advantages of tinplate packaging, the metal shell remains intact even under heavy loads and reliably protects the contents from external influences and preserves the recipe.

Lid securing clips are used for storing and transporting filled cans, which are slipped over the edge and can be removed by hand or pliers.

For the transport of mostly larger cans, handles or carrying handles are provided, which are either connected to the can or latched into corresponding receptacles on the side. The mounting brackets are then included in the cover, for example, and are snapped into the corresponding receptacles after removal.

A press-in lid is usually opened with a screwdriver or screwdriver or other mechanical tools such as a knife or a spatula, but also often with a key. After levering or opening the can, the can lid is to be removed and set aside. This is usually done by hand. Most of the time, the fingers come into contact with the product, eg paint or varnish. Wearing gloves is not always practical. When the can lid is closed, there is usually contact with, for example, the paint or residues that are on the underside of the can lid and may have run off over the edge. In addition, picking up the lid of the can is not always easy, depending on where it is stored or where it is stored.

Presentation of the invention

It is thus an object of the present invention to provide a moving element of the kind mentioned in the opening paragraph which overcomes at least one disadvantage of the known.

In particular, a movement element is to be provided that has a high level of acceptance among users in terms of applicability. In this case, said movement element should preferably be as simple as possible to attach and use, but also safe for transport and entail only low material costs.

It is an object of the invention to move a can end without touching it.

A further object of the invention is to be able to move a can end by hand in this way without bringing the hand or hands into contact with the contents.

Furthermore, it is an object of the invention to guide a can lid in such a way that it is easy to put down and pick up. At least one of these tasks was solved with a movement element according to claim 1.

One aspect of the present invention relates to a mover for a can end that includes a generally angled handle mountable on top of the can end.

The movement element is particularly suitable for can lids that are designed as patent lids or press-in lids and for cans with such lids, ie patent lid cans or press-in lid cans.

It is preferred that the angled handle has a substantially right angle. This ensures that the handle rests on one side of the can without taking up much space around a can. This is advantageous for storage and transport. One side of the handle then runs essentially parallel to the wall of the can. Depending on the design, a slightly acute angle is advantageous if the handle is to fit snugly against the can. In particular embodiments, where space is available, the angled handle may have a slightly obtuse angle, making the handle easier to pick up.

If the angled handle preferably comprises a metallic material, then the handle is robust and guarantees safe and stable guidance. Depending on the thickness, the stability can be guaranteed. If the metallic material comprises sheet metal or tinplate, i.e. material similar or identical to the can lid or can, then simple disposal and recycling is possible without first removing the handle and disposing of it separately.

In a particular embodiment, the angled handle is formed essentially as an elongated rectangle, ie the angled handle is formed by an essentially elongated rectangle. This allows simple production, for example using stamping tools. In another embodiment, the angled handle has a rounded end at one end and a substantially straight edge at the other end. The rounding reduces the risk of injury. The essentially straight edge at the other end ensures a clean finish on the inside edge of the lid. Depending on the width of the handle, it can be advantageous to round the edge slightly to match the inside edge of the lid.

If the shorter side of the angled handle does not substantially protrude inward beyond an edge of the can end, there is no risk of injury. In addition, less material is required for the handle.

Another aspect of the present invention relates to a can end having a generally angled handle attached to the top of the can end.

In a preferred embodiment, the handle is fastened on the upper side at the edge, which allows the handle to be easily fixed.

When the handle at the rim of the can end extends beyond the bottom, excellent grip is provided for placing and retrieving the can end upside down or upside down without touching the can end itself. Typically, when a can end is placed on top, liquid, i.e., paint or varnish, will drain from the bottom or residue that is on the bottom will drain down the sides. This happens depending on the position of the stored can lid. Since the handle at the edge of the can lid extends upwards beyond the underside, this area cannot be affected or wetted by the residue running off, so that the handle remains clean.

In one embodiment, the handle is attached or glued to the upper side of the can lid with a contact adhesive, which allows simple and subsequent attachment to cans or lids that have already been produced. In a further embodiment, the handle is connected to the can lid on the upper side by a soldered connection. This creates a firm connection between the handle and the can lid. Other connection techniques are also possible in further embodiments, but the associated costs must be taken into account.

It is particularly preferred to produce the can lid directly with the handle. Subsequent attachment of the handle would then not be necessary.

If the can lid has two handles, for example, then it would be possible to use both hands to guide the lid even more securely.

In another embodiment, the can lid includes three handles, allowing for upside-down placement for targeted draining as the three handles act as feet.

In a special embodiment, the handle has at least one magnetic area. For example, if the magnetic area is on the short side of the handle, the handle can be placed on the edge of the lid and removed again at any time. The functionality of the handle is also given in this embodiment.

A handle with a magnetic area can also be manufactured and offered as a separate tool for tin and tin cans. One side, preferably the longer side, can be designed and used to open the lid. Such a tool is capable of detaching a press-in lid from the can and then using the magnetic portion to attach the handle to the can lid and move, place and pick up the detached lid. The tool can be reused as often as you like.

Another aspect of the present invention relates to a method of moving a can end. The method includes the steps of providing a can end having a substantially angled handle, gripping the substantially angled handle, and moving the can lid by means of the handle.

Moving the can end using the handle may further include the step of raising and lowering the can end. The can lid is usually placed upside down. Residues of the filling, i.e. paint or varnish, then usually run over the edge, so that only a safe pick-up with a handle is guaranteed. It is advisable to place the can lid on a suitable surface. With paper, the lid usually sticks. However, this is advantageous with the handle, since lifting by means of the handle and counter pressure near the bond allows lifting or picking up safely.

Moving the can end with the handle may further include the step of picking up the deposited can end and positioning the can end over the mouth of the can. The lid can then be closed with the can by pressing it in. It is a great advantage that your hands stay clean and do not come into contact with the product, i.e. paint or varnish.

The present invention will now be explained in more detail below with reference to specific exemplary embodiments and figures, but without being restricted to these. For a person skilled in the art, further advantageous embodiments result from studying these specific exemplary embodiments. For the sake of simplicity, the same parts are given the same reference numbers in the figures.

In Fig. 1 shows a movement element 1 according to the invention in a lateral representation. The moving element 1 comprises a shorter side 6 and a longer side 7 which is designed as a handle 2 . The shorter side 6 has a fastening area 15 at the end. The shorter side 6 and the longer side 7 are angled towards one another and form an angle 4 which, in a preferred embodiment, is essentially a right angle. Advantageously, the lower end of the longer side 7 could also be bent outwards a little. This would enable better gripping behavior or picking up or gripping the handle 2 . The moving element 1 preferably comprises sheet metal or tinplate. The longer side 7 can contain recesses or punched-out portions that serve to reduce weight or for optical design. A covering over the handle 2 made of a different material, such as plastic or rubber, can have a positive effect on the gripping behavior.

2a shows a can 10 with a movement element 1 according to the invention in a three-dimensional representation. The box 10 is designed here as an end rear cover box. There is a can lid 12 on the can 10.

The can 10 and can end 12 are preferably made of tinplate. The can 10 is cylindrical and is rolled outwards at the upper edge of the can, which allows good emptying of residues thanks to a smooth edge. The fuselage panel is welded in a longitudinal joint (not shown). The bottom of the can 10 is seamed and the seamed joint is preferably sealed. For low-viscosity fillings, the can lid 12 can be provided with an expanded rubber seal.

The can lid 12 has a fixed moving element 1 on the upper side 13 . The moving element 1 is attached to the edge of the lid 14 and extends as a handle 2 along a side can wall 16 down. The handle has a curve 3, which can be seen better in FIG. In a preferred embodiment, the movement element 1 is fastened in the fastening area 15 on the cover edge 14 with an adhesive connection. Included a permanent adhesive or a metal adhesive is used. In a further embodiment, the movement element 1 is welded to the cover edge 14 in the fastening area 15 . A soldered connection between the lid edge 14 and the short side 6 of the moving element 1 is also possible. Depending on the material, other connection techniques can also be used. If the short side 6 is longer and extends over the lid edge 14 inwards at the bottom of the upper side 13, then the moving element 1 can be fastened to the upper side 13 with a rivet connection, for example. This allows for better leverage.

2b shows a can 10 with a movement element 1 according to the invention in a three-dimensional view. The can 10 is designed here as a patent lid can. The patent lid can is suitable metal packaging for chemical products, e.g. paints and varnishes, which can also be easily stacked. There is a can lid 12 on the can 10.

Again, the can 10 and the can lid 12 are preferably made of tinplate. The body of the can 10 is cylindrical. The can lid 12 is circular and has a moving element 1 fixed on the top 13 . The moving element 1 is mounted on the edge of the lid 14, which does not extend all the way to a wall 16 of the can. The moving element 1 extends downwards as a handle 2 along the lateral can wall 16 . In a preferred embodiment, the moving element 1 is fastened or glued to the lid edge 14 in the fastening area 15 by means of an adhesive. The short side 6 does not extend beyond the inner edge of the lid. In a further embodiment, the movement element 1 is soldered in the attachment area 15 on the cover edge 14 . A spot welded connection between the edge of the cover 14 and the short side 6 of the moving element 1 is also possible.

2c shows another can 10 with a movement element 1 according to the invention in a three-dimensional view. The box 10 is also designed here as a patent lid box. On top of the can 10 is a can lid 12 with a moving element 1 pointing towards the viewer. The body of the can 10 is also cylindrical here, but narrower than in Fig. 2b. The can lid 12 is circular and has a moving element 1 fixed on the top 13 . The moving element 1 is attached to the edge 14 of the lid. The moving element 1 fastened to the edge of the lid 14 extends downwards as a handle 2 along the side wall 16 of the can. The moving element 1 is firmly connected to the edge of the lid in the fastening area 15 . The short side 6 does not extend beyond the inner edge of the lid.

FIG. 3 shows a moving element 1 in the undeveloped state in a plan view. The moving element 1 has a shorter side 6 and a longer side 7 which are essentially separated by a bend line 8 . The longer side 7 forms a handle 2 or handle-like element. The longer side 7 has a rounding 3 at the end, as a result of which the risk of injury can be minimized. The shorter side 6 ends with an essentially straight edge 5 . In a preferred embodiment, the edge 5 is flush with the inner wheel of the can lid. Overriding would pose a risk of injury.

Fig. 4a shows a moving element 1 in the raw state in plan view. A substantially elongated rectangle 40 is shown, from which an angled handle 2 can be formed. The moving element 1 is produced as an elongated rectangle 40 from a sheet of sheet metal or tinplate by punching tools. Burrs are removed by light deburring.

Fig. 4b shows a moving element 1 after a first processing step in plan view. A rounding 3 is provided on one side, so that the risk of injury is minimized. In a preferred embodiment, the moving element 1 is stamped directly with the rounding 3 . Then the curve 3 no longer has to be created by machining. A light deburring would then be the next step before a bend or angling takes place.

4c shows a movement element 1 in a second embodiment in a lateral view. In this embodiment form the shorter side 6 and the longer side 7 a slightly acute angle. This is advantageous if the handle 2 is to fit snugly against the can wall.

4d shows a movement element 1 in a first embodiment in a lateral view. The moving element 1 is angled at the bending line 8 and forms a shorter side 6 and a longer side 7, which is used as a handle 2. The shorter side 6 and the longer side 7 form a substantially right angle.

4e shows a moving element 1 in a third embodiment in a lateral view, the shorter side 6 and the longer side 7 forming a slightly obtuse angle here. In these embodiments, easier pick-up of the handle is favored.

Finally, FIG. 4f shows a movement element 1 in yet another embodiment in a side view, the bend being designed as a rounding. This embodiment can be used with certain types of cans or lids if, for example, a straight bend is not appropriate.

FIG. 5 shows a cross section of a can lid 12 with a moving element 1 according to the invention. The can lid 12 has a top 13 and a bottom 11 . In addition, the can lid 12 has an edge 14 . A movement element 1 is fastened to the edge 14 in the fastening area 15 and has a handle 2 or handle area 2 . In this position, the can lid 12 with the moving element 1 is on a can.

FIG. 6 shows a can lid 12 with a moving element 1 according to the invention. The moving element 1 now protrudes with the handle 2 upwards. Paint or varnish residues 60 that are on the underside 11 of the can lid usually run over the edge 14 . Handle 2 is not affected. Thus, the handle 2 remains free of paint or varnish residues 60 and can therefore be gripped securely. Fig. 7a shows another embodiment of a moving element 1 with a magnetic area 70. The magnetic area 70 is located on the short side 6 and corresponds approximately to the attachment area 15. The magnetic area 70 can include a permanent magnet 70, which is in the attachment area 15 of the short side 6 is attached or permanently attached. Since tin packaging is magnetic, the magnetic area 70 of the moving element 1 can be placed on an edge 14 of a can lid 12 . After the can lid 12 has been opened, it can be lifted and moved by means of the handle 2 of the movement element 1 placed thereon. The force of the magnetic area 70 is decisive in determining how well the moving element 1 adheres to the can lid 12 . A fixed connection between the can lid 12 and the moving element 1 is omitted in this embodiment. In addition, the moving element 1 with a magnetic area 70 can be used multiple times, even as often as desired.

Fig. 7b shows yet another embodiment of a moving element 1 with two magnetic areas 70, 72. A first magnetic area 70 is located on the short side 6 and a second magnetic area 72 is located on the longer side 7. If a magnetic area 72 is located on the longer side 7, this can contribute to the stability of the moving element 1, since this then adheres better to a can wall.

The magnetic area 72 can also be attached to the outside of the handle 2 so that there is a magnetic connection with other cans. In this embodiment, however, the short side 6 should be firmly connected to the lid edge 14 in order to ensure basic stability.

8a shows a movement element 1 with handle 2 in a further embodiment with a larger magnetic area 70 in a three-dimensional representation. In this embodiment, the moving element 1 has a longer magnetic region 70 which extends on the top side 13 of the can lid to approximately the middle of the can lid. The side 6, which is short in the previous exemplary embodiments, is longer here, possibly of the same length as the handle or even longer. This provides a larger contact surface between the moving element 1 and the top 13 of the can lid 12. If the moving element 1 has two similar or identical magnetic areas 70, 72 and the sides are approximately the same length, then it doesn’t matter how around the moving element 1 is put on. This ensures rapid availability and applicability.

8b shows a three-dimensional representation of a moving element 1 in yet another embodiment, with the moving element 1 extending over the can lid 12 and having two selective magnet areas 81 , 82 .

FIG. 9a shows a movement element 1 in a further embodiment with an angular deflection in a side view. In this embodiment, the magnetic area 70 is placed securely on the top side 13 of a can lid.

9b shows a movement element 1 in a further embodiment with a rounded bend in a side view. Depending on the lid edge 14, the angling can be adjusted in order to meet the corresponding application needs.

By means of the angled handle 2, a can lid 12 can be easily moved, lifted, rotated or turned inside out, but can also be picked up again and placed on a can. Contamination with the contents, such as paint or varnish, can be avoided.

The present invention is applicable to all metal packaging made of tinplate and containers that include a lid, such as press-lid cans or patent-lid cans, press-lid buckets, patent-lid buckets, ring buckets or pails, hobbocks, etc. and all volumes. The application examples for such metal packaging are diverse: lacquers and paints, wood preservatives, sealants, adhesives, lubricating greases, pastes, casting compounds, Bitumen, resins, adhesives, printing inks, emulsion paints, greases, and chemical products.

The present invention shows a moving element, a can end, a can and a method for moving a can end. It goes without saying that numerous other embodiments are conceivable for a person skilled in the art on the basis of the exemplary embodiments described.
