Plougmann & Vingtoft Patentbureau .__ (54) Metal cans contained a can body and a removable bowl-shaped lid.

The invention relates to a metal box with a can body and a removable bowl-shaped lid.

Such cans are widely used for products that are sensitive to humidity and changes in the atmosphere and yet have to be stored for a period of time between manufacture and consumption. The thin biscuit cans, widely used in retail, are an example of how to try to balance the requirement for the can to protect the product and withstand the effects of modern distribution, and the requirement that the can be as cheap as possible . As food manufacturers want to make the most of their production facilities throughout the year despite seasonal fluctuations in demand, the need for better packaging is growing. Thus, it is desired that the cans 1) can be attractively decorated to promote sales, 2) are designed to have good moisture barrier properties to keep the packaged product in good condition, 3) to be stackable so that they can be placed on pallets for storage and transport; 4) are easy to open and close once the consumer has used some of the product; and 5) are able to withstand the forces involved in applying adhesive tape or hermetic closure. and by a gentle treatment.

A wide variety of embodiments of such metal cans are known in which the can lid and the can body, when the filled packaging is delivered to the consumer, are interconnected by means of a metal exterior wall mounted on the can body in which a tear is paralleled by parallel pivoting lines. strip (for example, U.S. Patent No. 1,846,739 and No. 2,295,540 and English Patent No. 475,790). When a container of this known kind is first to be opened by the user, the tear strip is torn off and the lid can then be removed and reattached as a normal lid having a lower part which is inserted into the mouth of the can body or caused to enclose it. However, cans of this known type with tear strip are relatively expensive to manufacture and furthermore have the disadvantage that when tearing off the tear strip sharp edges are formed on which one can easily cut.

Cans are also known in which the cup-shaped lid has a flat upper end wall and a lower rim forming a narrowed portion which can be accommodated in the can mouth. This known lid is furthermore provided with a peripheral surface which, when the lid is fitted, aligns with the outer surface of the can wall body side. A can of this known type can be made moisture-proof by covering the dividing line between the flushing surface parts of the lid and the can body by means of an adhesive strip. Opening this known can, which can be formed with a smooth and smooth surface, avoids the formation of said sharp tearing edges, but the can has the disadvantage that it is not stackable.

The can of the present invention is of the latter type with a can body whose sidewall above hair has a rolled rim defining a can orifice and a removable bowl-shaped lid whose peripheral wall has a constricted portion adapted to be sealingly accommodated in the can orifice. such that outer circumferential surface portions of the can body side wall and the peripheral wall of the cap, respectively, are adjacent adjacent to each other and flush with each other so that the dividing line between these surface portions can be covered by applying an adhesive strip or other layer of adhesive material thereto, and the can of the invention is characterized in that the constricted portion of the cup-shaped lid is located at the closed end of the lid and that the peripheral wall of the lid at the open end of the lid is such that it can enclose at least one of the of the ends of the can body.

When the filled can is delivered to the retailer or the consumer, it can be hermetically sealed by an adhesive strip, and since the bowl-shaped lid is open upwardly, it can receive the lower end of another corresponding can, i.e., the can of the invention is stackable. When the can is reached by the consumer, the possibility of stacking the cans may have become irrelevant, and the lid may then possibly be placed on the can body with the closed end upwards, which means that the lid is caused to enclose the top end of the can body in the closed state of the can. .

In the following, various embodiments of the can of the invention will be described in more detail with reference to the drawing, in which 1 is a perspective view of a first embodiment of the can according to the invention with a can body and a lid mounted thereon; FIG. 2 is a longitudinal section in the embodiment of FIG. 1 can be stacked on another corresponding can of which only a portion is shown; FIG. 3 shows the can lid placed in a different closing position on the can body; FIG. 4 corresponding to FIG. 1 shows another embodiment of the can according to the invention; FIG. 5 is a section similar to that of FIG. 2, but in this second embodiment, when stacked on another corresponding container; FIG. 6A on a larger scale and in modified form a detail of the one shown in FIG. 5; FIG. 6B a different can body roll than that shown in FIG.

4 - 6, FIG. 7 corresponding to FIG. 1 shows a rectangular biscuit box having curved sides which constitutes a third embodiment of the can according to the invention; 8 is a top view of four cans such as those of FIG. 7 is positioned in one of the can bodies ready to be stacked as shown in FIG. 8A, FIG. 8A shows, in perspective, how two can bodies for the ones in FIG.

7 and four lids as shown in FIG. 8 can be placed in other two can bodies when they are to be delivered to the manufacturing stage where filling takes place; FIG. 8B is a sectional view of the section of FIG. 7; FIG. 9 is a sectional view of a can which forms a fourth embodiment of the can of the invention and which is stacked on the lid of another corresponding can; and FIG. 10 shows a corresponding section in a fifth embodiment of the can according to the invention.

The FIG. 1, the first embodiment of the can or container according to the invention has a circular base view and consists of a can or container body 1 and a lid 2 which is tightly closed by adhesive tape 3. The lid is decorated so that it can be used as a tray when it is used. no longer needed to close the can body. As with all other embodiments of the container of the invention which will be described below, the can body and lid are made of decorated tin plate. However, it is possible to use other sheet metal.

In FIG. 2, it appears that the lid 2 has a plug-shaped part 4 which can be pushed into the mouth of the can body formed by an inward roll 5. The lid has an annular ledge 6 which engages with the roll 5 for determining the axial position of the lid. can body. An upwardly extending cylindrical portion 7 extends circumferentially around the ledge 6 and its free edge is in the form of an outward roll 8. The rollers 5 and 8 prevent the user from cutting on the edges. In addition, they make the edges stiffer and prevent damage. The lid portion 7 has the same outer diameter as the can body 1 so that the outer cylindrical surfaces of the lid and can body align with each other where they are adjacent to each other. The two surfaces are also adjacent to each other. Therefore, the adhesive tape 3 can be easily applied either completely or with little wrinkling over its length.

The adhesive tape 3 serves not only to seal the connection between the lid and the can body, but also to retain the lid of the can body and prevent relative movement between them. Furthermore, the can body roll 5 will be prevented from moving inwardly of the cap-shaped portion 4 of the lid, which also substantially prevents damage to the can body during handling and transport, with the lid in particular preventing the can body wall from bending inwards, which is why the can body may be of a relatively thin material. .

If desired, outwardly projecting bulges (not shown) may be formed on the plug-shaped part 4, which serve to engage the underside of the can body roll 5, thereby giving a positive retention of the lid to the can body.

The lower part of FIG. 2 shows how the container can be stacked on top of another corresponding container. The bottom 11 of the container body 1 is of the embedded type so that the side wall 10 of the container extends all the way down to the bottom of the container and therefore fits into the upwardly cylindrical portion 7A of the lower lid 2A. Although the portion 7A of the drawing has an outwardly slightly conical shape to facilitate stacking, it may be cylindrical.

FIG. 3 shows how, if desired, the lid 2 can be reversed and the container closed, the lid being used as a push-on lid.

The second embodiment of the container according to the invention shown in FIG. 4 to 6, has a container body 1 which does not (as the first embodiment) have a bottom of the embedded type, but instead has a double sonar projecting from the cylindrical side wall 21. The lid 12 has, as previously mentioned, a plug-shaped part 14 and a sealing ledge 16. In the corner or shoulder formed between the ledge 16 and the plug-shaped part 14, a liner mass 18 is placed in the closed position, this liner mass 18 is held down against the container body 1 by means of a bulge 13 of the plug-shaped portion of the lid engages the container body roll-over 15, as shown in FIG. 5 and 6A. An adhesive tape or label 3 may, if desired, be applied to the upwardly extending lid portion 17 and to the can body for further attachment or decoration. In both of these cases, the casing mass improves the closure efficiency.

FIG. 5 shows how the container can be stacked on another corresponding container despite the double seam 21. This is because the lids 12 and 12A have a stacking ledge 19 which is surrounded by an upwardly extending peripheral part in the form of a roll 20 preventing any lateral movement. sliding of the stacked cans.

In FIG. 5, the connection between the lid 12 and the can body 1 is shown sealed by the adhesive tape 3 to show how the can can be used in two ways, namely a) with adhesive tape serving as a seal during storage and with the bulges 13 to improve re-closing, or b) with the liner mass 18 which increases the storage capacity both in the warehouse and in the consumer.

The 1-6A containers are round, but may have other cylindrical shapes or any other shape.

The FIG. 7 can consist of a can body 1 and a lid 2, of which the can body 1 has a rectangular cross-section with curved sides.

Although the can is shown with a double stitch 3 connecting the side wall to the bottom, other forms of connection between the bottom and the wall, e.g. bottoms of the embedded type are used. The can body has a side seam 4 which, in a preferred embodiment, is disposed near one of the corners of the can. The lid 2 has a lid wall 5 with a peripheral plug-shaped portion 6, an outer portion 7 and an upwardly extending portion 8 on which adhesive tape 9 shown in a partially stripped condition can be applied.

In FIG. 8 it can be seen that four lids 2A, 2B, 2C and 2D can be placed diagonally together within a can body 1. This is possible because the diagonal length of the cans is greater than the long sides of the lids and also because the plug-shaped part of each lid can be accommodated in the adjacent bowl-shaped lid - e.g. the lids 2C and 2D - thereby reducing the overall thickness of the composite lids. When a second can body is placed in the bottom of the first can body 1, the group of lids will be enclosed.

In FIG. 8a, it appears that the containers can be further arranged within each other, whereby the space occupied during transport

decreases. Inside the box 1A, a few more cans 1B and 1C are placed, and a fourth can ID (shown in dashed lines) is placed on top of the bottom, so that four cans and their corresponding lids can be shipped while receiving as little space like that usually occupied by two cans.

FIG. 8B shows part of a section in the embodiment of FIG. 7. The can body 1 has a base 14 which is connected to the can body wall 15 by means of an internally located nail 16. The lid 2 has a lid wall 5, a plug-shaped part 6, an outside part 7 and an upwardly extending part 8 which ends in a outward rolling 17.

The upwardly extending portion 8 of the lid 2 is expanded to allow for the uptake of a second stacked container body 1A (shown in dotted lines). The plug-shaped portion 6 of the lid 2 is provided with a snap portion 13 which may be in the form of protruding bulges or of a bead.

The FIG. 7, the container shown is preferably made of thin metal plate such as tinplate or aluminum plate and not only gains its strength due to the curvature of the side walls, but also due to the engagement of the plug-shaped lid with the can body.

FIG. 9 shows a further embodiment, in which in FIG. 1 and 2, simple lid 2 is mounted on a container body 1 which has a wide outward rolling 24 which forms a surface which can be used for applying adhesive tape and which can cooperate with the adhesive tape part of the lid 2. The adhesive tape part 17 on the lid can receive a double stitch 21 on a corresponding container stacked thereon.

FIG. 10 shows how a lined lid 2, having a stacking ledge 6 and a roll-up 8, can accommodate a double seam 21 on a can 25 which has a narrowing bottom.

Although the embodiments shown in FIG. 2, 3, 5, 6A, 6B, 8B, 9 and 10 are particularly described in relation to the respective containers shown in FIG. 1, 4 and 7, they can each
