Description

The The invention relates to a container with closure element and a device for its manufacture, wherein the container from at least one container body with a Floor area and a floor area opposite Edge region and at least one substantially cup-shaped, one-sided open closure element, in particular in the manner of a membrane film is provided, which consists of a base and a perimeter area.

container of this type are in a variety of embodiments for food, beverages, stimulants, personal care products etc. known. The closure elements have the task for to ensure a secure and tight seal. They should but can also be opened quickly or be easily removable.

For example, containers are used in the packaging industry, which at their upper open end have an outwardly directed peripheral flange on which a closure element in the form of a membrane is fastened (eg. DE 23 18 670 . DE 29 33 944 ).

On Reason for the external connection area between Closure element and container body is the risk damage and thus unwanted opening the container is relatively large. In addition, this requires Arrangement of the closure element also enlarged Dimensions of the container with a corresponding space requirement.

It In addition, containers were developed in which the closure elements not disposed on an outboard flange, but in the edge region of the container on the inner surface be attached.

So will in DE 198 02 016 A1 describes a container whose opening is covered with a sealing membrane attached to the container inner wall by sealing. The closure membrane in this case has an upwardly bent edge, with which it is sealed to the container inner wall.

In DE 25 20 501 A1 discloses a can with a can closing the can opening membrane, wherein the edge of the membrane continues parallel to the can inner wall in a cylindrical part. This cylindrical, cup-shaped part is also open at the top and glued to the can inner wall.

Such closure elements with raised in the direction of the container edge edge regions are, for example, also made DE 44 31 758 A1 and from EP 0 819 086 B1 known.

One Disadvantage of these known solutions is that due to the arrangement shown or attachment of the closure element (Membrane, foil) the possible filling volume not can be fully used. Which is between the Ground or the base of the cup-shaped, upwards - from Container interior away - directed closure element and the upper edge of the container body Part is seen as a loss of usable volume. It hangs that can be used when filling these containers Volume with constant outside dimensions also of the width of the connection area, which at the connection the peripheral region of the closure element with the container inner wall is formed. The wider this connection area is formed is, the lower this is for the filling usable volume.

One Another disadvantage is that due to a closed Tank of possibly overpressuring the base of the closure element is outward bulges and a release or tearing off cause the peripheral region in the outer connection region can.

These Containers provide so-called single-chamber containers dar because between the closure element and the bottom only one cavity (a Chamber) is present for filling.

However, containers with two or more chambers are known from the prior art, which serve to accommodate different contents. In DE 199 10 674 A1 is described a double cup for receiving food, wherein a second cup is arranged on a first cup spaced. Between both cups a closed cavity is present, in which, for example, spoons, straws and other items can be stored.

there Both cups are by means of a releasable connection device held together. This connection device can be a screw connection, a plug connection or a bayonet connection, the is arranged outside the double cup and thus the Disadvantage that in addition to poor stackability unwanted opening is easily possible.

This disadvantage has the in DE 36 27 535 A1 described Mehrkammerdose not on. The sheet metal box has a hull, a bottom, a lid and an intermediate shelf the one with a raised edge. The hull has at least one bead lying in a plane, wherein arranged approximately in the height range of the bead of the intermediate bottom and is positively connected to the hull. Also, the intermediate floor may be provided with such a bead, which corresponds to the bead arranged in the trunk. A seal is achieved by a sealant, which is introduced into the beads.

at However, certain applications, the attachment of Beads on the can body or on the closure element and the additional introduction of a sealant not possible or at least not be desired.

The The object of the invention is a container with Closure element and a device for its production after to provide the generic term of the first and 35th claim for protection, in which a maximization of the filling volume can be achieved is and at the same time the connection area of closure element and container body against an undesirable Separation is protected.

These Task becomes with the characteristics of the first and 37th protection claim solved. Advantageous embodiments will be apparent from the Dependent claims.

According to the invention the open side of the closure element to the container interior, wherein the peripheral area completely or partially with the Container body is connected. The closure element has one between the base and the peripheral area formed angle, which is not equal to zero. In this case, the peripheral area forms the closure element with the inner wall of the container body at least one common connection area, which is within one of the base of the closure element, of the container body and enclosed by the bottom portion Area is located. The usable for the filling Volume is within one of the floor area, from the container body and the base the open side of the closure element enclosed area. The connection area extends either over the entire peripheral region of the closure element or only on Parts of the peripheral area.

The Base surface of the closure element can essentially be formed circular. You can also choose one of have the circular shape deviating design. Dependent on from the design of the edge region of the container body can be between the base area and the perimeter area The angle formed by the closure element different sizes exhibit. In decreasing towards the edge area Cross section of the container body is the angle greater than 90 °. In the direction of the Randbereiches enlarging cross-section of the container body the angle is less than 90 °.

The transition from the base to the peripheral region of the closure element can be rounded. Was the closure element z. B. produced by deep drawing, the transition region correspond to the shape of the drawing punch. The closure element is in the edge region with the inner wall of the container body connected. But the closure element can also be in a between the bottom area and the edge area located area of the container body be connected to the inner wall. Here are the peripheral area the closure element and the container body in the connection area cohesively connected to each other. This can be done, for example, by sealing, gluing, welding or soldering done. The peripheral region of the closure element and the container body may be in the Connection area with or without heat input and with or connected without additional connection medium be.

The Closure element is advantageously preformed already cup-like. The closure element can with an additional and / or be provided integrated opening element. But it can too without additional and / or integrated opening element be used.

Furthermore For example, the shutter member may be an area to be opened have distinctive marking. These are on the base the marker located the marking element is preferably embossed and / or printed or formed in the form of a coating.

It can also at least two closure elements with the Be connected inside wall of the container body, wherein a closure element in the edge region and the other closure element in another, between the edge area and the floor area located portion of the container body is. It is between the first closure element, which in the between the edge area and the floor area area is arranged, and the second closure element in the edge region a first chamber and between the first closure element and the bottom portion of the container body a second Chamber available.

Both chambers can be filled with similar or different contents. But it can also be filled only one chamber with filling material and in the other chamber are objects below be brought. It may be in the chamber means such. As advertising materials, utensils or Gebrauchsshinseise (also in combination with each other) may be arranged. Both the closure element arranged in the edge region of the container body and the closure element in the further region of the container body can be designed according to the invention.

It but can also be arranged in the edge region closure element represent any closure element and only the closure element, which divides the can into two chambers, designed according to the invention be.

B. done by sealing.

Becomes a preformed cup-shaped closure element from the direction it supplied to the edge area, drives the unpopulated Fixing stamp from the direction of the floor area through the interior the can up to the edge area or over the edge area. Then the closure element is supplied to the fixing punch. The fixing punch is already in the mounting position can now the closure element on the inside of the can (the container) be attached (eg by sealing).

is the fixing punch when receiving the closure element still over the edge area, he will after loading with the closure element back toward the floor area moves until the closure element in the desired Fixing position is located, whereupon then the closure element is attached to the inside of the container.

The Invention will be described below by way of example explained in more detail.

It demonstrate:

1a : schematic, perspective view of a cylindrical container with closure element;

1b : Section of a cylindrical container with retracted toward the edge region wall portion and adjoining cylindrical portion with closure element;

2 : an enlarged detail in a sectional view 1 ;

3 : schematic, perspective view of a dual chamber container;

4 a dual chamber container with an object in a chamber;

5a a cylindrical container body with a closure member located on a fixing punch prior to insertion;

5b a cylindrical container body having a fastener located on a fastening element in the fastening position;

6 a container body which tapers conically in the edge region with a closure element located on a fastening punch in the fastening position.

A container has according to 1a a cylindrical container body 1 and a floor area 2 on. The floor area 2 opposite is on a border area 3 within the container body 1 a cup-shaped closure element 4 arranged, with its open side to the container interior, ie in the direction of the bottom portion 2 shows.

To 1b The cylindrical container has a retracted wall area in the direction of the edge region 1.1 with rejuvenating Diameter, to which a cylindrical area with closure element 4 followed.

The closure element 4 has a round base here 4.1 and a peripheral area 4.2 placed on the inside of the container body 1 is present ( 2 ).

Between the base 4.1 and the peripheral area 4.2 An angle α is formed which has a value not equal to zero. In this case, this angle α can assume different sizes. In the illustrated embodiment, the container body 1 a uniformly extending cylindrical cross section. The angle α between the base 4.1 and the peripheral area 4.2 of the closure element 4 here is approximately 90 °. Between the peripheral area 4.2 of the closure element 4 and the inside of the container body 1 there is a connection area 5 , which represents a cohesive connection. In this case, the connection area 5 over the entire circumference 4.2 extend. But he can only on parts of the peripheral area 4.2 be limited. In the latter case, the peripheral area 4.2 over the connection area 5 only partially with the inner wall of the container body 1 connected.

Connecting peripheral area 4.2 and container body 1 in the connection area 5 Can be done by means of sealing, gluing, welding or soldering. It can be carried out with and without heat input and with and without additional connection medium.

On the ground 4.1 , preferably in the edge region, there is a mark 4.3 , which has been applied by pressure or embossing or coating, and which indicates the area to which the opening of the container (closure element 4 ) required force F should act. By force on the mark 4.3 dissolves over the connection area 5 with the inner wall of the container body 1 connected peripheral area 4.2 from the container body 1 and the container is opened. Alternatively, a per se known opening element (not shown) can be used, which in the closure element 4 is integrated or which is additionally attached. But it can also be dispensed with an opening element. Then an opening can be simply by finger pressure on the mark 4.3 respectively.

When the container is filled, the connection area is located 5 within the volume occupied by the contents, ie within one of the bottom portion 2 , from the container body 1 and from the base 4.1 the open side of the closure element 4 enclosed area. The width of the connection area 5 has no influence on the size of the usable volume. The size of the possible filling volume depends - with the same dimensions of the container body 1 - of the arrangement of the base 4.1 of the connecting element 4 within the container body 1 from. Preferred is one with respect to the end of the container body 1 at the edge 3 only slightly recessed arrangement of the base 4.1 , whereby a maximum utilization of the filling volume of the container can be achieved. Because the connection area 5 is located within the container, there is a good protection against external forces, which tearing the closure element 4 could cause. When the container is filled, a possibly occurring overpressure P can additionally be added to the connection area 5 act and thereby presses the peripheral area 4.2 against the inner wall of the container body 1 thus supporting the effect of the compound.

In 3 is shown a further embodiment in which two closure elements 4 . 6 be used. The closure element 6 represents here any closure element and is - as described in the previous embodiment - in the edge region 3 of the container body 1 arranged while the other, closure element according to the invention 4 in an area between the edge area 3 and the floor area 2 located area of the container body 1 is attached. It can also both shutter elements, ie in the edge region 3 arranged and in the between border area 3 and floor area 2 arranged to be formed according to the invention. This is in 4 shown. Between the first closure element 4 and the second closure element 4 or 6 there is a chamber K1 and between the first closure element 4 and the floor area 2 another chamber K2.

Both chambers K1, K2 can be filled with similar or different filling material. It can also be filled with filling material only one chamber K2, and in the other chamber K1, for example, serving for consumption object is housed. Here you can find the widest variety of objects such as everyday objects, printed matter, advertising material, information about birth, toys ( 4 ) be housed singly or in combination.

The container body 1 In addition to the circular cross section described here, it may also have a shape deviating from the round shape. A corresponding design (circular or a different shape) then also shows the closure element 4 , which may be a molded membrane, a molded film (cohesive film or adhesive film) or a shaped laminate. The container may, for example, a Do se, represent a canister or a ring. The material used may be aluminum, steel, cardboard, composite or plastic.

The inventive arrangement of the closure element 4 can be used for both stackable and non-stackable containers. Prerequisite for a stackability is a corresponding design of the edge area 3 or the floor area 2 or the use of an additional element, for. B. a lid. The connection area 5 experiences thereby due to its advantageous design and arrangement within the container no burden.

The manufacture of the container with closure element 4 is done as follows:
In the initial state of the still unfilled container consists only of the container body 1 , The two front sides, the bottom area 2 and the opposite edge area 3 , are open.

The border area 3 can here as well as the container body 1 prepared or unprepared, ie bevels, edge indentations ( 1a ) and / or rollers, or there are no formations / deformations.

The closure element 4 is advantageously preformed cup-shaped and has an approximately cylindrical shape, wherein the between base 4.1 and peripheral area 4.2 formed angle α is approximately 90 °. The transition area from the base area 4.1 to the peripheral area 4.2 may be rounded here.

According to 5a is the closure element 4 on a mounting stamp 7 and takes its form. The closure element 4 can already aligned or unaligned to the container body 1 are located.

For the purpose of attachment will now be the closure element 4 preferably with the base 4.1 proceeding from the direction of the open floor area 2 by means of a fixing stamp 7 in the container body 1 brought in. The fixing stamp moves 7 with the closure element 4 through the interior of the container body 1 up to the attachment position of the closure element 4 , The pressing of the peripheral area 4.2 to the inside of the container body 1 takes place in the edge area 3 , where the connection area 5 to be produced ( 5b ). In this case, the connection of closure element 4 and container body 1 in the connection area 5 realized by a contact force, which by means of the located in the container interior punch 7 and one on the outside of the container body 1 at the height of the connection area 5 arranged counter-holder 8th is achieved.

After the cohesive attachment, z. B. by means of seals, the peripheral area 4.2 on the inner wall of the container body 1 the filling of the container takes place over the still open bottom area.

Finally, the floor area 2 closed, which should not be explained here.

The container according to the invention with closure element 4 is characterized by the achievement of a maximum filling volume and by the realization of a secure closure.

In this case, the introduction of the closure element 4 with its open side ahead into the container body 1 also from the direction of the edge area 3 respectively.

In 6 is a container body 1 with himself in the edge area 3 shown conically tapered cross-section. The preparation of a connection of closure element 4 and container body 1 takes place analogously to 5a and 5b , It comes here only a conical punch used and as a counterhold a suitably shaped tool.

The Stamp 7 can be radially elastically deformable.

Also the production of a double or multi-chamber can be done analogously the described embodiment.

When using a plurality of closure elements according to the invention 4 First, this is the edge area 3 of the container body 1 to be attached closure element 4 over the open ground area 2 in the container body 1 introduced. After its attachment, z. B. by means of sealing, in the existing cavity - the future chamber K1 - the desired object, eg. As a toy introduced. Then the second closure element 4 over the open ground area 2 introduced into the container interior and also experiences a cohesive attachment. Thus, the chamber K1 was created with the appropriate content. Now, the future chamber K2 can be filled with the desired contents, and subsequently also the bottom area 2 closed.

It is easy to imagine that in this way even more closure elements 4 introduced and correspondingly more chambers can be created - of course, depending on the dimensions of the container body 1 ,

In the case of using any closure element 6 However, its attachment can take place in a different way.

Compared to the solutions of the prior art in which it is in the case of an inside of the closure element 4 effective overpressure can come to a detachment of the connecting portion of the container body, acts in the inventive arrangement a possibly resulting inside pressure D stabilizing the connection area 5 , It may also be a bulge of the base 4.1 of the closure element 4 come, but at the same time the perimeter area 4.2 of the closure element 4 to the inner wall of the container body 1 pressed.
