Containers that can be opened with an opener by tearing open a wall

The invention relates to one with an opener by tearing it open a container that can be opened from the wall, the lid of which can be removed by means of score lines running in the wall of thinner Mcterial thickness than that of the wall is limited.

Most containers are designed for easy opening require a rigid-armed, one-piece opener and a mechanical action generated by it when breaking a pre-notched part of the container wall. If so far the effect of a one-armed lever has been used to open it a part of the force used to open the container was lost to create a starting point for the opener, i.e. e.g. when a rivet or other means has been used to secure the opener to the container. "., if the effect of a two-armed lever was used, 30 was a first breakaway from a rupture of the container wall under voltage dependent. These disadvantages were found when using rolled sheet for the containers.

For emptying soup cans, meat cans and the like it is appropriate that essentially the entire container wall is removed. It is especially difficult to open by hand Containers in a sturdy yet easy-to-open design

Establish leadership when these are to be fully opened. In addition, the end walls of the container often have to Profiles are provided, e.g. 3. with reinforcement ribs to to prevent bulging of the front wall * This is why such front walls are very difficult to bend during opening.

There are numerous suggestions for solving this problem. So it was suggested to provide a tear strip that, from starting from a centrally located breakthrough area, all around runs the circumference of the front wall. Such an arrangement is disadvantageous because the relatively small tear strip breaks inclines and leaves sharp edges to grasp when you want to pull out the front wall completely "

Furthermore, it is not yet possible to complete an end wall to remove, with the pouring openings in the container are closed, because the bending or kinking of the "edge parts to be removed and tearing along closely spaced I’s lines A prerequisite for the production of such pouring openings is. Tools for easy opening are not available, if you want to create a complete opening, especially when reinforcing ribs are present.

The invention has the task of addressing the disadvantages and Avoid difficulties. To solve this problem it is proposed according to the invention that at least one "eil the circumference of the lid has two basket lines running side by side are provided that limit an intermediate tear strip that an opener in the zuii on the tear strip open correct position is attached that the opener "when lifting its handle the one score line as a two-armed lever and the other score line tears open as a one-armed lever and that the further opening of the container by pulling off the Tear strip takes place.

The invention used, so a combination of one, one-armed and a two-armed lever, avoids a spiral wound tear strip in one completely

Openable container and put out the application of very strong material such as sheet metal Container walls with or without reinforcement ribs, as they are required to control a high pressure when Filling often occurs during manufacture or treatment. The advantages of the invention apply to a simple opening both of fully openable containers and just pouring holes.

Containers produced according to the invention are easier to open because the entire force required for a first breakaway is fully utilized by arranging the opener as a combined one-armed and two-armed lever. In this embodiment, the force applied between the attachment point of the opener and its handle and acts on the container wall, is in a high! Let ouch to break eusgenutzt a score line through the üxrkung a two-armed lever, but G ^enes the advantages of a one-armed lifting 1ε not lost.

The possible use of rolled sheet or other relative Solid LIrteriol for the ~ 5eha.itervx.nd is therefore also available. Partly because this results in the attachment of the opener to the Container used fastening means .Iu the dimensions can also be small. With weak round material you do not use small-sized fasteners, although they are appropriate, because there is little material the container wall required for forming the fastening means is. This in turn allows the attachment to be provided close to the periphery of the container turn. The formation of greats. Fasteners can weaken a container wall if the material is stretched to do so. This is particularly important, if the weakened area is close to the circumference of the container wall, because under these circumstances the container wall bulges out tends. However, there is also an arrangement of attachment close as 1εη <ϊ of the container wall is possible, so this allows the use of a larger handle for the opener to

'Achieving the greatest possible mechanical effect.

Although the invention is used with good advantage in sheet metal containers Can be made of other materials including plastic, aluminum and other metals and including Laminated metal foils can be used. And if you can also 'by attaching the opener to the container wall by means of If a rivet has particular advantages, other types of fastening, including welding, can be used.

Some of those proposed by the invention are also suggested below Mentioned advantageous configurations, while further configurations are mentioned in the embodiment described below. So it is beneficial if the ilerblines at those points at which they are to tear open first, have scribe points of thinner material thickness and if the scribing points are as close as possible and each on one side of the fastening point of the opener.

It is also beneficial if it is close to the attachment point of the opener the tear strip is widened towards the middle of the lid and if the course of the inner score line on the tear strip forms a tongue. The attachment tongue formed by the tear point of the inner score line is then advantageously directly under the opener and is from its attachment point on Tear strips removed so far that the tongue is broken loose a little earlier than the tear point of the outer score line.

Further objects and advantages of the invention will become apparent from the following description of various embodiments of the invention illustrated in the accompanying drawings are.

deckling 14 * The removable part or cover 2o generally has a circular shape.

There is an inner score line 22 in the cover 2o. Dieee Score line 22 lies inwardly on a smaller radius than score line 18. Over part of its length the inner score line 22 is equidistant from outer score line 18 and extends around the circumference of lid 2o on an arc of about 180 °. Score lines 18 and 22 together form an arcuate tear segment or strip 24, which is smaller in width in relation to the cover 2o. The tear strip 24 is on a larger part its length in the course of its opposite sections 26 and 28, which at opposite parts of the L'erbline 22 lie about the same width. The tear strip 24 also contains a central part Jo of different widths.

The cover 2o has a circular reinforcing rib 34 and a deeper central part 36 (see also FIG. 3). Such a profile reinforces the cover and prevents it from bulging during filling and processing. In cross section, the tear strip 24 has the shape of a reinforcing rib or a v / ulstes (I ⁷ I ^ m 2).

On the middle part Jo of the ice strip 24 is by means of a rivet 4-0, which is made from the metal of the cover 14 in the usual way an opener J8 is attached. The rivet 4-0 consists of a head 4-2 (Figure 3) and a shaft 44-, the opener 38 has a hole 5o for pushing through the Ntetschaftes 4-4- and a countersink 52 for receiving the rivet head 4-2. The opener 38 is of elongated shape and solid construction and is made of sheet metal, with its edges bent down all around. The opener 38 has an annular handle 46, which extends from the rivet 4-0 in the direction of the I. -itte the cover Ί4 extends. A mandrel extends from the rivet 4o in the opposite direction to that of the handle 4-6 48 of the opener 38. When the handle 46 and the mandrel 48 are not resting anywhere, the opener 38 can act as a lever, its Base in the area of the rivet 4o. The grip of the handle 46 is made possible by the recessed box of the central part 36 facilitated, so de that a special finger pressure on the cover 14 is not required for this purpose.

The inner score line 22 and the outer score line 18 have scribe points 54- and 56. The scribing points 54- and 56 are located on opposite sides of the rivet 4o and belong to the middle part 3o of the tear strip 24.

Although the ITiet 40 holds the opener 58 on the cover 14, it is possible that the opener is misaligned by a rotary movement about the N.et in a plane approximately parallel to the cover in relation to the scribing points 54 and 56. In order to suppress such movement, the cover 14 has close to the two sides of the opener J8 a pair of projections 57 (Figure 1 I. The protuberances 57 can be a rotational movement of the opener 38 is not to.

The scribing point 54 of the inner score line 22 is below of the opener 38 and has a lug 58 that extends from the rivet 4o extends away. The extension tongue 58 is slightly rounded and forms a continuation of the with a projection-like shape Tear strip 24.

The scribe 56 of the outer score line 18 is with the Mandrel 48 of the opener 38 in contact. The mandrel 48 is over the scribing point 56, so that when the mandrel 48 is moved in the direction of the cover 14 it is close to the scribing point can exert a pressure on this point of the tear strip. ·

The scribing point 54 of the inner score line 22 has one such Position that they break out of the cover 14 when the handle 46 is moved in the direction of the arrow 6o (FIG. 3) can be. This represents one of the important advantages of the invention. The one directed upwards onto the handle 46 acting force is transmitted via the head 42 and the shaft 44 of the EP-ets, so that the tear point 54 by the effect a two-armed lever (Figure 4) broken out and the force that would otherwise be used when creating a base for the opener is lost, is used to open the container. The lug 58 at the score line 22 facilitates through summarizing a deformation in the area of a point a first break. · The movement of the handle 46 from the Cover 14 away also causes movement of the mandrel of opener 38 towards the cover, so that the mandrel 48 exerts a localized pressure on the tear strip 24 at the tear point 56 of the outer score line 18. So works when the handle 46 is moved, so does the opener 38 as a one-armed lever, and the mandrel 48 breaks the scribing point 56 of the outer score line 18 (Figure 5)

The arrangement of the outer score line 18 close to the folded seam 15 not only increases the size of the lid 2o, but also: also allows the container rim to break for a first time bend the score line.

It seems better to make the outer score line 18 in the outer surface of the cover 14 to break open the Scribing parts 56 to facilitate. Then there is for that through the force exerted on the mandrel 48 less the possibility of a , larger distribution. So although the arrangement of the score line on the outside is preferred, the score line can be used on the inside.

Although the scribing point 54 of the inner score line 22 will in practice generally break up earlier than the scribing point 56 of the outer line. 13, the breaking point of the two scoring points will be close together in time. The tearing point 54 of the inner score line 22 should break open first, to provide an air passage through which dei> pressure inside and outside of the Ben old ex ¹ s can compensate In such cases, the normally closed contact 38 acts as a shield v spouting of the container old content by dia air opening;. the leader of a prevents such pressure equalization, after the marking points of both Iverblinien are broken by the double leverage of the opener 38, the opener 38 is pulled up and over the cover 14 in the direction of the arrow 61 (Figure 6) : iet 4-0 from in opposite directions. Initially, the tearing directions diverge from each other and then approach cn Ziide d With the tear strip gradually becoming a pearl, when the opener yQ is pulled away from the cover 14, the Iloiss strip 24 fades out, which facilitates opening because of the favorable sealing of the pulling force components.

keeping the amount of latent laimens bent during the opening process small to facilitate opening. The width of the hot strip will change to match the size of the container and the thickness of the material. In a fully openable tinplate container, for example with a diameter of about 2.6 ", the tear strip can have a" width of about 0.125 " The rivet is generally uniform. At the location of the rivet, the distance between the tab 58 of the tear point 54 of the inner score line 22 and the tear point 5S of the outer score line 18 is about 0.279 ". The center of the rivet 40 is about 0.13 "from the attachment point 58 of the inner herb line 22. The distance from the cement of the rivet 40 to the outer!" Erb line 18 is about 0.148 ". The scribing parts of the inner score line 22 should generally run et v / ao, 1 "in all seals from the middle of the ITiets 4o and a. Steel strip of about 0.008" thickness should be ironed, including a possible rake of the hoop 24 To prevent years of handling of the opener 38. The diameter of the rivet shaft 44 is about ο, ο ^Γ / 5 "before the standardization of the rivet head 42. The shape of the cross section of the tear strip 24 runs in the area of the rivet 4o relatively flat, in order to prevent the material change from being influenced by the rivet and without taking into account the manufacture of the rivet assembly which is required for fastening the opener 38.

A circular punched piece with a desired profile, which is produced in a known manner, is used to produce a tear strip 14. Then the production of the rivet is started by deforming part of the cover in suitable press rams and an elevation is created at the point provided for the rivet. If the press die is used, the size of the elevation is reduced, λ This process allows the production of small rivets without the metal of the strip tearing. After the rivet has been made, the score lines are made and an opener is placed on the rivet. Then the rivet head is molded to secure the cover opener. The order of the process steps mentioned for shaping and manufacturing the rivet can be changed if desired. If the sheet metal "cover has a material thickness of 0.008", the score lines 18 and 22 can receive a remaining material thickness of about 0.015 ^w , or the remaining material thickness can be ^{increased to about 0.03 n} or reduced to 0.0005 " depending on the requirements placed on the container, |

Figures 8 and 9 show a container for liquid Content is determined. Such a container 62 has a top cover 64 in which an upwardly rising reinforcing rib rises 66 is located. A continuous outer Eerbl line 68 in cover 64 forms a removable lid 7o, which has the shape of a pouring opening and which occupies a smaller surface part of the cover. In the cover 7o runs a inner score line 72 which together with score line 68 forms an arcuate tear segment or tear strip 74 ". The inner score line 72 has a marking point 76 and a marking

sentence tongue 78. On the outer score line 68 there is one Marking point 8o. The scribing points are on opposite sides of a rivet 82 with which an opener 84 on the Cover 64 is attached (FIG. 9. The opener 84 and a head on the rivet 82 are not shown in FIG. 8 for reasons of clarity.

If the handle 86 of the opener 84 is moved in one direction away from the cover 64, the opener 84 breaks the tear-off points 76 and 8o due to its effect as a one-armed and two-armed lever in rapid succession, -as it is above in connection with the Figures 5, 4 and 5 has been described. If you pull the opener 84 away from the cover 64 after a first break, it runs the tearing along the score line 68 to the end of the lid 7o. When the ripping is complete / is the Cover 7 ° completely free. The contents of the container can be emptied through a pouring opening which is released by the removal of the 'lid 7o.

An approximately U-shaped, upwardly raised guide rib 88 prevents a rotational movement of the opener 84 about the rivet 62 in a plane approximately parallel to the cover 64 and thus prevents an accidental movement Incorrect position of the opener 84 in relation to the scribing points in the notches. The guide rib 88 also reinforces the container walls to prevent bulging, ensures the possibility of bending over when first broken open and protects the lips of a person drinking from the container from the rough edges of the pouring opening. A sunk Surface part 71 in the cover 7o reinforces it and makes it easier gripping the opener 84.

The opener 84 is generally wedge-shaped, with its opposite Sides diverge in a direction away from the ITiet 82. The sides of the opener 84 cross the outer score line 68 near ITiet 82. This Jüaordnunr; is beneficial in some ways. One of the advantages is a slight spread along the open side

the achieved by the breaking of the score line 68 i opening when the mandrel of the opener 84 and adjacent parts of the tear strip extend a short distance into the container. Spreading the opening prevents the tear strip from hooking on the edges of the opening when it is pulled out again through the opening in a later phase of the opening process.

FIG. 1o shows a container 9o with an openable side wall. An outer score line 92 defines a removable "closure tab 94 of the side wall 96 of the container 9o. An inner score line 93 runs around a portion of the perimeter of the closure tab 94 and, together with the outer score line 92, forms an arcuate tear segment or tear strip 100.
