[0001] Patent application
[0002] Container, injection mold for producing such a container, and method for changing the dispensing opening during the production of such a container
[0003] The present invention relates to a container comprising a plastic container body produced by injection molding, which forms a receiving space, wherein the container has a container opening and a closure for closing the container opening. The invention further relates to an injection mold for producing such a container and a method for changing the opening cross-section of the dispensing opening during the production of such a container.
[0004] Such containers require a closure that reliably seals the container. This is intended to prevent the product contained in the container from leaking out. At the same time, the closure can protect the product contained in the container from environmental influences, thus increasing the product's shelf life. Furthermore, there is also an interest in designing the closure in such a way that it is easy to see whether the closure has already been opened. Such closures are also known as tamper-evident closures or tamper-evident closures. They are used primarily in the packaging of food and pharmaceuticals. However, they can also be effectively used in the packaging of other goods.
[0005] DE 37 27 965 A1 discloses a package comprising a container with a container opening and a screw cap that can close the container opening. Furthermore, the screw cap includes a closure body that extends over the container opening and can be removed via a finger tab, allowing any attempt at opening to be detected. US Pat. No. 8,746,476 B1 describes a closure for a bottle that has a closure body that extends over the container opening and can be removed via a finger tab, allowing any attempt at opening to be detected.
[0006] The invention is based on the object of providing a container with a plastic container body produced by injection molding, which has a reliable warranty function and is easy to handle. The invention is also based on the object of providing an injection mold for producing such a container and a method for changing the opening cross-section during the production of such a container, thereby improving the handling of the container.
[0007] The object is achieved with the features of claim 1. The container according to the invention comprises a container body made of plastic, produced by injection molding, which forms a receiving space, wherein the container has a container base, a side wall, a container section, a container opening, and a closure for closing the container opening, wherein the container section (17) is arranged on the side of the container (100, 100', 200, 200') opposite the container base (15), wherein the container section has the container opening, wherein the closure has a closure body which is assigned to the container opening and closes the container opening, wherein the closure body has an edge section and a tear-off section, wherein the tear-off section is connected to the edge section via a web section which forms a predetermined breaking point, wherein a tab is arranged on the tear-off section,wherein the tear-off section has an outer contour such that after removal of the tear-off section, a dispensing opening is formed which is smaller than the container opening.,
[0008] Such a container makes it possible to determine whether the container has already been opened. To open the container opening for the first time, the tear-off section is separated from the edge section by pulling on the tab, so that the web section forming a predetermined breaking point is inevitably severed. The edge section can remain assigned to the container opening after the initial opening, while the tear-off section is separated from the container. This makes it easy to determine whether the container is still originally sealed or has already been opened. Such closures are also known as tamper-evident closures. The tab can be designed in such a way that a tensile force is applied to the tear-off section. The container can be produced cost-effectively in large quantities while maintaining a high level of process reliability.This is particularly due to the fact that the container body can be manufactured as a plastic part using the injection molding process. The receiving space is suitable for storing various goods and in particular for storing piece goods or bulk goods such as chewing gum or sweets. In addition, the container can be highly leak-proof. This makes the container suitable for a wide variety of applications and in particular for storing moisture-sensitive goods such as food, dietary supplements, pharmaceuticals, chemicals, chewing gum and / or test strips. The container is particularly suitable for holding solid, pieced goods, which can then be dispensed in measured amounts through the dispensing opening. Good handling can be achieved in particular if the dispensing opening is large enough so that the goods from the receiving space can only pass through the dispensing opening one at a time.The solid, piece-like goods can preferably be accommodated in the receiving space as tablets, capsules, dragees, pressed bodies, and the like. Furthermore, the container is also suitable for receiving and dispensing liquids. In particular, the opening area of the dispensing opening can be smaller than the opening area of the container opening. After removal of the tear-off section, the dispensing opening is delimited by the edge section, so that the dispensing opening delimited by the edge section can be smaller than the container opening. Preferably, the edge section encloses the dispensing opening. This makes it possible to achieve a smaller dispensing opening regardless of the size of the container opening, and the size of the dispensing opening can be adapted to the goods accommodated in the receiving space in order to improve the removal process.For example, in a container for small products, the dispensing opening can be made small, even if the container opening is larger. However, if larger products are to be packaged and dispensed through the dispensing opening, the dispensing opening can be made larger, up to the size of the container opening.
[0009] An advantageous embodiment of the invention provides that the tear-off section is designed such that the dispensing opening has a different basic shape than the container opening. The basic shape of the dispensing opening can thus be designed independently of the basic shape of the container opening. As a result, the basic shape of the dispensing opening can be adapted to different dimensions and / or shapes of the goods (e.g. small or large objects) or a desired dispensing speed of bulk material in order to improve the removal process. In addition, handling can be improved because the size of the dispensing opening can be determined independently of the size of the tab. This is particularly advantageous if the dispensing opening is to be designed to be considerably smaller than a finger's width.
[0010] Preferably, the basic shape of the dispensing opening is angular (e.g., rectangular), circular, or elliptical. In a particularly preferred embodiment, the dispensing opening is oval. A circular, elliptical, or oval design of the dispensing opening is advantageous because it reduces the risk of jamming when removing items.
[0011] Advantageously, the web section is designed as a closed line. The web section surrounds the tear-off section, so that the tear-off section can be completely removed by pulling on the tab when the web section is removed. Preferably, the web section forms the outer contour of the tear-off section.
[0012] Particularly advantageously, the outer contour of the tear-off section is designed as a kink-free line. This reduces the risk that the tear-off section will not be completely separated from the edge section at a kink due to a sudden change in direction of the outer contour, and that parts of the tear-off section will remain as remnants on the closure body even after the tear-off process, partially closing the dispensing opening. This further improves the opening of the container. "Kink-free" indicates that the outer contour does not exhibit a sudden change in direction.
[0013] Preferably, the outer contour does not have a straight section.
[0014] Furthermore, it can advantageously be provided that the container opening has a container opening edge formed by a circumferential, projecting collar. The collar can preferably be oval or circular. The collar is preferably designed as a pouring edge to improve the removal process of bulk material. The collar can protrude from the edge portion. The collar preferably protrudes to a side facing away from the receiving space. The dispensing opening and / or the edge portion are preferably arranged within the space enclosed by the collar.
[0015] Advantageously, the closure body is arranged in the container opening. In this case, the outer contour of the closure body can correspond to the inner contour of the container opening edge, thereby creating a tight connection between the closure body and the container opening edge.
[0016] In addition, it can be provided that the tear-off section and the edge section are designed such that the dispensing opening takes up less than 95% of the surface area of the closure body. Preferably, the opening surface of the dispensing opening takes up less than 90%, 85%, 80%, 75%, 60%, 50%, 40% or 25% of the surface area of the closure body. Preferably, the edge section completely surrounds the dispensing opening, so that the closure body is arranged on the entire inner circumference of the edge section. The opening surface of the dispensing opening is smaller than the surface area of the closure body and can be adapted to the size of the goods stored in the receiving space in order to improve the removal process. In this way, the same container can be used for dispensing objects of different sizes by simply adapting the closure body.A further advantageous embodiment of the invention provides that the tear-off section has a first region and a second region, wherein the first region has a first width and the second region has a second width that is less than the first width. In this way, the first region can form the dispensing opening with a first clear width of the edge section that is greater than a second clear width of the edge section formed by the second region. Preferably, the second clear width is less than 80% of the first clear width, particularly preferably less than 50% of the first clear width. Preferably, the second clear width is more than 5% of the first clear width. The first width of the first region and the second width of the second region can be coordinated with one another such that the removal of pieced goods is only possible via the dispensing opening formed by the first region.The opening formed by the second area can, for example, serve as a pressure equalizer to adjust the withdrawal speed.
[0017] Furthermore, it can advantageously be provided that the dispensing opening is arranged off-center relative to the container opening and / or the collar. Preferably, the container can have a side wall, with a center of the dispensing opening being arranged closer to the side wall than a center of the container opening. This facilitates the dispensing of bulk material when the container is tilted, since the container can be tilted in such a way that the dumping height can be reduced, thus improving the removal process. Preferably, the center of the dispensing opening is formed by the center of the first region.
[0018] Advantageously, it can be provided that the tear-off section has a third region which has a third width. Preferably, the third region forms a third clear width of the edge section. Preferably, the second region is arranged between the first and the third region and connects the first to the third region. Preferably, the third width is smaller than the first width and greater than the second width. It can be provided that the third clear width is smaller than the first clear width and greater than the second clear width. Preferably, the tab is arranged on the third region. As a result, the first width of the first region, which forms the dispensing opening, can be adapted to improve the removal of the product from the receiving space, while the third width of the third region is adapted to improve force transmission when the tab is pulled onto the tear-off section.The second width of the second area can be selected to ensure the stability of the tear-off section, particularly during the tear-off process. The second and third widths can be selected to allow removal of the product from the receiving space only through the dispensing opening. Furthermore, during injection-molded production, the tab can be determined independently of the size of the dispensing opening.
[0019] According to the invention, it is preferred that the first width, the second width and the third width are determined in a direction perpendicular to the longitudinal direction of the tear-off section.
[0020] Advantageously, it can be provided that the dispensing opening is designed symmetrically to the longitudinal direction of the tear-off section, in particular axially symmetrically.
[0021] According to an advantageous embodiment of the invention, it can be provided that the second region is elongated and narrower than the first region. Preferably, the second region is narrower than the first and / or the third region. The second region can be provided as a connecting region between the first region and the third region. The second width of the second region can be selected such that stability of the tear-off section is ensured, in particular during the tear-off process. The second width can be designed such that removal of the product from the receiving space through an opening formed by the second region is prevented.
[0022] An advantageous embodiment of the invention provides that the first region has a first outer contour and the second region a second outer contour. In this case, it can be provided that a radius is formed in a first connecting section between the first and the second outer contour. Furthermore, it can be provided that the third region has a third outer contour. In this case, it can be provided that a radius is formed in a second connecting section between the second and the third outer contour. The first and the second connecting section are preferably designed without kinks. This enables easier opening of the closure body. The radius between the first and the second or the second and the third outer contour makes it possible to remove the tear-off section without tearing the tear-off section at the transition between two adjacent outer contours, thus further improving the opening of the container.
[0023] Furthermore, it can advantageously be provided that the closure body is flat. Preferably, the tear-off section is also flat. Preferably, the closure body and / or tear-off section are flat and / or plate-shaped. Furthermore, it is preferred if the tear-off section and the edge section are arranged in one plane.
[0024] Furthermore, the closure body can be provided with a region of reduced material thickness that forms the predetermined breaking point. Preferably, the region of reduced material thickness forms a closed line. The closed line can form an outer contour of the tear-off section.
[0025] Advantageously, it is provided that the thickness of the closure body is between 0.1 mm and 4 mm. The thickness of the closure body is preferably more than 0.2 mm, particularly preferably more than 0.3 mm. The thickness of the closure body is preferably less than 3.5 mm, particularly preferably less than 3 mm. As a result, the container opening can be securely closed by the closure body. In this case, it can be provided that the web section has a smaller thickness than the edge section and / or the tear-off section. As a result, the tear-off section can be separated from the edge section using manual force and without tools. Preferably, the material thickness in the region of the web section is 50% or less than the material thickness of the tear-off section and / or the edge section. According to the invention, it can be provided that the tab is arranged within the space enclosed by the collar.Preferably, the tab has a rest position in which it does not protrude beyond the collar. It can be provided that the tab does not protrude beyond a side of the space enclosed by the collar facing away from the receiving space. This can prevent, in particular, unintentional pulling on the tab and thus unintentional tearing off of the tear-off tab.
[0026] Preferably, the tab is designed as a finger tab. Such a finger tab can be grasped with one or more fingers to remove the tear-off section.
[0027] Furthermore, it can advantageously be provided that the tab forms a ring. Preferably, the tab is designed as a closed ring. The closure can then be opened particularly easily by inserting a finger into the tab. Particularly preferably, the tab has an inner diameter that is larger than the diameter of the dispensing opening or the first region. Furthermore, it can be provided that the outer contour of the tab is arranged parallel to the inner contour of the collar. A distance can be formed between the tab and the container opening edge. This simplifies the operation of the tab in order to more easily remove the tear-off tab from the container. In addition, production by the injection molding process is simplified.
[0028] According to another embodiment, it can be provided that the tab forms a tongue which is arranged on the tear-off section.
[0029] Advantageously, the tab can be provided with an opening that has a larger clear width than the dispensing opening. A finger can be inserted into the opening of the tab to exert tension on the tab and thereby tear off the tear-off tab. By designing a sufficiently large opening in the tab, the tab can be particularly easily operated while simultaneously ensuring that the dispensing opening is sized to suit the product.
[0030] In addition, the container may be provided with a base plate at the bottom. The base plate forms part of the exterior of the container on which the container can stand.
[0031] Good handling is enhanced if the container has an oval, round, or square basic shape. The base can preferably be oval, round, or square.
[0032] Furthermore, the container opening can be arranged off-center on the container. Preferably, the container opening is arranged such that the collar and the side wall lie partially in one plane and form a sliding surface. This allows the bulk goods to slide along the sliding surface from the receiving space through the container opening when the container is tilted, thus improving handling during removal.
[0033] Furthermore, it can advantageously be provided that the container has a first container component that forms the container section, which has the container opening and comprises the closure body with the edge section, the tear-off section, and the web section. Furthermore, the container can have a second container component. This can comprise the container base. The side wall of the container can be provided between the container base and the container section, which has the container opening. The side wall can be formed by the first and / or the second container component. In this way, the container can be assembled from a few parts, which simplifies production and makes it more cost-effective.
[0034] According to the invention, it is advantageous if the first and second container components are connected by a plug-in connection. The plug-in connection can be designed to be sealing. Another type of sealing connection between the first and second container components is also possible. The plug-in connection can be designed, for example, in that one of the first or second container components has an insertion section that is inserted into the other of the first or second container components. The plug-in connection makes it possible to largely freely define the shape of the container. This contributes to good handling, since a narrow container design fits better in the hand. In particular, it is not necessary to design the container components in a circular shape, as would be necessary with a screw connection.
[0035] According to a particularly preferred embodiment, the first and second container components can comprise a locking device that positively connects the first and second container components to one another. The locking device prevents accidental release of the connection between the first and second container components. This prevents the first and second container components from separating from one another when the tab is pulled forcefully. The locking device thus contributes to achieving a high level of security against accidental separation of the first and second container components.
[0036] The locking device can have a locking recess and a locking projection, wherein the locking projection engages in the locking recess and positively connects the first and second container components. The locking projection can be designed, for example, as a locking lug. The container can absorb the force exerted by a user on the closure body using the tab until the tear-off forces necessary to tear off the closure body are reached, without separating the first container component from the second container component. This ensures the guarantee function of the closure body and additionally provides protection against unintentional opening, for example by children. Furthermore, the first and second container components are securely connected to one another.
[0037] The locking projection can be formed on one of the first and second container components, while the locking recess is provided on the other of the first and second container components. Furthermore, the locking device can have more than one locking projection and more than one locking recess. It is conceivable for the first and second container components to have both locking projections and locking recesses. The locking projections of one container component can engage the locking recesses of the other container component.
[0038] The locking device preferably comprises more than one locking recess. Particularly preferably, the locking device comprises more than two locking recesses. Preferably, the locking device comprises fewer than eight locking recesses. Particularly preferably, the locking device comprises fewer than six locking recesses. In particular, the locking device comprises four locking recesses.
[0039] Preferably, the locking device comprises the same number of locking projections as locking recesses. It is also conceivable for the locking device to comprise more locking projections than locking recesses, with several locking projections engaging in one locking recess.
[0040] According to the invention, the first container component can be manufactured in an integral design as a coherent injection-molded plastic part. The aforementioned injection-molded part can be manufactured in one piece in an injection mold.
[0041] According to the invention, the second container component can be manufactured in an integral design as a coherent injection-molded plastic part. The aforementioned injection-molded part can be manufactured in one piece in an injection mold.
[0042] In this way, the first and / or second container components can be produced particularly cost-effectively and in large quantities with high process reliability. The container body manufactured by the injection molding process can comprise the first and / or second container components.
[0043] According to the invention, the web section can be formed by a groove arranged on the side of the closure body facing away from the receiving space. This contributes to easier production, since the web section can be formed in the injection mold by a tool with a projection arranged on the outside of the container.
[0044] An advantageous embodiment of the invention provides that the first or second container component comprises a lid for closing the container opening. After the container opening has been opened for the first time, the lid can be used to reclose the container opening by removing the tear-off element. This allows for repeated opening and closing of the container opening.
[0045] This makes it possible to gradually remove the goods from the container's receiving space. Preferably, the first container component includes the lid. The lid is preferably a section of the first container component.
[0046] Furthermore, it can advantageously be provided that the lid is movably arranged on the first or second container component. Preferably, the lid is movably arranged on the container section. For this purpose, a hinge can be provided between the lid and the container section. The hinge is preferably designed as a film hinge, in particular as a butterfly hinge. The hinge can form an (imaginary) axis of rotation for the lid. The lid can assume an open position and a closed position.
[0047] Advantageously, the lid is designed as a flip-top lid. For this purpose, the lid is connected to the first or second container component in such a way that the first or second container component is manufactured with the lid as a single, integral injection-molded plastic part. The injection-molded part can be manufactured in one piece in an injection mold.
[0048] Furthermore, it can advantageously be provided that the lid has a base and a skirt arranged thereon, which, in the closed position of the lid, extends in a direction from the base toward the container body. The skirt can be arranged at the edge of the base.
[0049] In addition, a sealing section can be arranged on the base, which seals the container opening in the closed position. A particularly good seal is achieved if the sealing section has a sealing collar that rests against the collar of the container opening when the lid is in the closed position. Particularly preferably, the sealing collar rests against the collar of the container opening with pre-tension when the lid is in the closed position.
[0050] Preferably, the base has a projection that forms the sealing collar. This can improve the sealing effect of the container when the lid is in the closed position.
[0051] Advantageously, it can be provided that a first distance between the first region and the hinge is greater than a second distance between the third region and the hinge. This makes it possible to ensure that the tab arranged on the third region is arranged closer to the hinge than the first region forming the dispensing opening. In order to tear off the tear-off element, tension is exerted on the tear-off element via the tab. Due to the described arrangement of dispensing opening, tab, and hinge, the direction of the tension to be applied can point towards a side facing away from the hinge. This can improve handling.
[0052] An advantageous embodiment of the invention provides that the container has a child-proof lock comprising a first locking element and a second locking element, which can assume a locking position relative to each other, in which the lid cannot be opened, and a release position in which the lid can be opened. This provides a high level of security against unauthorized opening of the container by small children.
[0053] Advantageously, it is provided that the first securing element is formed by a portion of the apron and comprises a recess arranged in the apron, and the second securing element is arranged on the container body and has a locking portion which engages in the recess in the locking position.
[0054] Furthermore, it can advantageously be provided that the locking section has an actuating surface on its outer side and that the locking section can be moved from the locked position into the release position by pressing the actuating surface. This results in a container that is easy and intuitive to use: the child safety lock is opened by pressing the actuating surface. Once the locking elements have been moved into the release position in this way, the lid can be opened. At the same time, a high level of security against unauthorized opening, for example by small children, is achieved, since opening the lid requires various coordinated movements. In particular, the locking section, which is protected and arranged in the recess, must be pressed down in a targeted manner, after which the lid can be moved into the open position.
[0055] A particularly advantageous embodiment of the invention provides that the container has two recesses and two locking sections are provided, wherein one of the recesses with the associated locking section is arranged on one side of the container and the other of the recesses with the associated locking section is arranged on the other, opposite side of the container. In this way, intuitive operability is achieved. The container is particularly well protected against unauthorized opening by small children, since the lid can only be opened if both locking elements are actuated simultaneously. A preferred embodiment of the invention provides that the second securing element is movably arranged and can be moved between the locking position and the release position. This contributes to good operability.Preferably, the second securing element automatically assumes the locking position, while it must be moved into the release position by applying pressure. It is particularly preferred if the second securing element can be moved from the locking position to the release position by applying pressure from the outside to the inside on the actuating surface, and if the second securing element automatically returns to the locking position without pressure.
[0056] A further improvement in usability is achieved when the actuating surface is larger than 25 mm 2 and preferably larger than 60 mm 2 Furthermore, it is preferred if the actuating surface is smaller than 900 mm 2 and in particular less than 200 mm 2This allows the actuating surface to be easily felt and pressed down with a finger. At the same time, accidental opening by small children is prevented, as the child safety lock can only be moved into the release position by pressing precisely on the actuating surface.
[0057] An advantageous embodiment of the invention provides that the second securing element has a web on which the locking section is arranged, wherein the web has a smaller width than the locking section.
[0058] According to the invention, it is preferred that the recess be open on the side facing the container body when the lid is in the closed position. This contributes to ease of use and also enables a compact and cost-effective design.
[0059] Preferably, the recess has a recessed area, with the skirt forming a blocking section between the recessed area and an edge of the skirt. The blocking section of the skirt enables a positive fit with the locking section. This prevents the lid from being opened when the child safety lock is in the locked position. The blocking section is preferably formed by a wall section of the skirt.
[0060] Furthermore, it is advantageous if the recess has a first recess width at one edge of the apron and a second recess width in a section spaced from the edge, which second recess width is greater than the first recess width.
[0061] A preferred embodiment of the invention provides that the locking section has a curved contour at least in sections on its edge facing the apron.
[0062] Particularly preferably, the locking portion and the recess have a congruent shape, at least in sections. This contributes to good and safe operation. A small gap between the locking portion and the recess is harmless. Preferably, the locking portion and the recess have a congruent shape (not only in sections). In this way, the skirt and the locking portion form a substantially closed envelope. This protects the lid from penetrating dirt.
[0063] Further improving usability is the apron's pressure surface, which moves the second locking element into the release position when the lid is closed. This allows the lid to be closed particularly easily, with the child safety lock engaging.
[0064] An advantageous embodiment of the invention provides that the container has a desiccant chamber. According to the invention, the desiccant chamber can be arranged on the container section. The desiccant chamber preferably has a cylindrical wall. The desiccant chamber is preferably filled with a desiccant such as silica gel. A side of the desiccant chamber facing the receiving space can comprise a moisture-permeable material. The desiccant can effectively reduce the air humidity in the receiving space. This allows even moisture-sensitive substances to be stored in the container for longer periods.
[0065] The object underlying the invention is also achieved by an injection mold for producing a container according to the invention. The injection mold preferably comprises a tool that defines a surface of the closure body, wherein the tool comprises a core and a jacket movable relative thereto, wherein a cavity is formed between the core and the jacket to form the tab, wherein the core and / or the jacket have a projection to form the web portion, wherein the tool is arranged replaceably in the injection mold. Preferably, the core is enclosed by the jacket.
[0066] The invention further relates to a method for changing the opening cross-section of the dispensing opening during the production of a container of the type described, which is produced by injection molding. The method preferably comprises the following steps:
[0067] - Providing a first tool defining a surface of the closure body, the first tool comprising a core and a shell, the core and / or shell having a projection to form the web portion;
[0068] - Providing a second tool which delimits a surface of the closure body, wherein the second tool comprises a core and a jacket, wherein the core and / or jacket have a projection in order to form the web section; wherein in the first tool and the second tool the projection forming the web section is designed differently such that in a container produced with the first tool and a container produced with the second tool the size and / or the shape of the dispensing opening is different, wherein the first and the second tool are interchangeable, wherein in order to change the opening cross-section of the dispensing opening the first or the second tool is inserted into an injection mold.
[0069] By equipping the injection mold with either the first or second tool according to the aforementioned method, the injection mold can be easily adapted to produce containers with differently shaped dispensing openings. This contributes to significant cost savings, as different containers can be produced with one injection mold.
[0070] Further objects, features, advantages, and possible applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawings. All described and / or illustrated features, individually or in any meaningful combination, constitute the subject matter of the invention, regardless of their combination in individual claims or their interrelations.

[0087] Figure 1 shows a first embodiment of a container 100, comprising a container body 2 made of plastic, produced by injection molding, which forms a receiving space. The container 100 has a container opening 4 and a closure 45 for closing the container opening 4. The closure 45 comprises a closure body 5, which is assigned to the container opening 4 and initially closes the container opening 4.
[0088] The closure body 5 has an edge portion 6 and a tear-off portion 7. The tear-off portion 7 is connected to the edge portion 6 via a web portion 8, which forms a predetermined breaking point 9. The web portion 8 is designed as a closed line and surrounds the tear-off portion 7. A tab 10 is arranged on the tear-off portion 7 to facilitate removal of the tear-off portion 7. The edge portion 6 is formed by a region of the closure body 5 that encloses the tear-off portion 7.
[0089] The tear-off section 7 has an outer contour so that after removal of the
[0090] Tear-off section 7 forms a dispensing opening which is smaller than the container opening 4. In the illustrated embodiment, the opening area of the dispensing opening is somewhat smaller than the opening area of the container opening 4. After removal of the tear-off section 7, the dispensing opening is delimited by the edge section 6. The edge section 6 completely surrounds the dispensing opening. The web section 8 forms the outer contour of the tear-off section 7, which is designed as a kink-free line. In the embodiment illustrated in Figure 1, the container opening 4 and the dispensing opening each have a circular shape.
[0091] The container opening 4 has a container opening rim 12 formed by a circumferential, projecting collar 13. In the illustrated embodiment, the collar 13 is circular and designed as a pouring rim to improve the removal process of bulk material. The collar 13 protrudes to a side facing away from the receiving space 3. The dispensing opening is located within the space enclosed by the collar 13.
[0092] The closure body 5 is arranged in the container opening 4. The outer contour of the closure body 5 corresponds to the inner contour of the container opening edge 12, thus creating a tight connection between the closure body 5 and the container opening edge 12.
[0093] Closure body 5 and tear-off section 7 are flat, planar, and plate-shaped. Tear-off section 7 and edge section 6 are arranged in one plane.
[0094] The closure body 5 has a region with reduced material thickness, which forms the predetermined breaking point 9. The region with reduced material thickness forms a closed line, which forms the outer contour of the tear-off section 7. In the embodiment shown in Figure 1, the closed line is circular.
[0095] The thickness of the closure body 5 is between 0.1 mm and 4 mm. The web section 8 has a smaller thickness than the edge section 6 and the tear-off section 7. The material thickness in the region of the web section 8 can be 50% or less than the thickness of the closure body 5. The web section 8 is formed by a groove 14, which is arranged on the side of the closure body 5 facing away from the receiving space 3. Therefore, the groove 14 can be formed by a tool section of the injection mold, which is arranged on the side of the closure body 5 facing away from the receiving space 3.
[0096] In the illustrated embodiment, the tab 10 is designed as a finger tab and forms a ring. A gap is formed between the tab 10 and the container opening edge 12.
[0097] The tab 10 is arranged within the space enclosed by the collar 13. In the illustrated embodiment, the outer contour of the tab 10 is arranged parallel to the inner contour of the collar.
[0098] The container 100 comprises on its underside a container base 15 (not visible in Figure 1), a side wall 16, and on the side of the container opposite the container base 15, a container section 17 having the container opening 4. The container 100 forms a container base on the container base 15.
[0099] Figure 2 shows a second embodiment of a container 100'. The second embodiment of the container 100' predominantly has the features of the above-described first embodiment of the container 100 from Figure 1. Therefore, the same reference numerals are used for parts with the same function. Reference is made to the above description. Additional or different features are described below.
[0100] In the embodiment of Figure 2, the tear-off section 7 is designed such that the dispensing opening has a different basic shape than the container opening 4. The tear-off section 7 and the edge section 6 are designed such that the dispensing opening takes up less than 60% of the area of the closure body 5. Further configurations are possible, for example, in which the opening area of the dispensing opening takes up less than 95%, 90%, 85%, 80%, 75%, 60%, 50%, 40%, or 25% of the area of the closure body 5. The opening area of the dispensing opening is smaller than the area of the closure body 5 and is adapted to the size of the goods accommodated in the receiving space 3.
[0101] In the embodiment shown in Figure 2, the shape of the dispensing opening differs from the shape of the container opening. Here, the tear-off section 7 has a first region 21 and a second region 22, wherein the first region 21 has a first width and the second region 22 has a second width that is less than the first width. In this way, the first region 21 can form the dispensing opening with a first clear width of the edge section 6 that is greater than a second clear width of the edge section 6 formed by the second region 22. The dispensing opening is designed to be axially symmetrical to the longitudinal direction of the tear-off section. For better clarity, the first, second and third widths B1, B2, B3 are plotted in the embodiment of a tool 40' for producing a container shown in Figure 10.Even if the tool 40' is intended for a different embodiment of a container, the design of the tear-off section 7 corresponds to the design of Fig. 2.
[0102] The second clear width is less than 80% of the first clear width. For example, configurations are also possible in which the second clear width is less than 50% of the first clear width. The second clear width is more than 10% of the first clear width. The first width B1 of the first area 21 and the second width B2 of the second area 22 are coordinated such that the removal of piece goods with dimensions larger than the second width is only possible via the dispensing opening formed by the first area 21.
[0103] The tear-off section 7 has a third region 23 with a third width B3. The third region 23 forms a third clear width of the edge section 6. The second region 22 is arranged between the first and the third region 23 and connects the first with the third region 23. The third width B3 is smaller than the first width B1 and greater than the second width B2. The third clear width is smaller than the first clear width and greater than the second clear width. The tab 10 is arranged on the third region 23. The second width B2 and the third width B3 are selected such that the removal of the product from the receiving space 3 is only possible through the dispensing opening 11 with the width B1.
[0104] The second region 22 is elongated and narrower than the first region 21 and the third region 23. The second region 22 is provided as a connecting region between the first region 21 and the third region 23.
[0105] The first region 21 has a first outer contour, the second region 22 has a second outer contour, and the third region 23 has a third outer contour. A radius 47 is formed in a first connecting section 24 between the first and second outer contours and in a second connecting section 25 between the second and third outer contours.
[0106] In the embodiment illustrated in Figure 2, the dispensing opening is arranged off-center relative to the container opening 4 and the collar 13. The container 100' has a side wall 16, with a center of the dispensing opening being arranged closer to the side wall 16 than a center of the container opening 4. The center of the dispensing opening is formed by the center of the first region 21.
[0107] In the embodiment shown in Figure 2, the tab 10 has an inner diameter that is larger than the diameter of the dispensing opening or the first region 21. The tab 10 forms an opening that has a larger clear width than the dispensing opening.
[0108] Figures 3a to 3f show a third embodiment of a container 200. The third embodiment of the container 200 predominantly has the features of the above-described first embodiment of the container 100 from Figure 1. Therefore, the same reference numerals are used for parts with the same function. Reference is made to the above description. Additional or different features are described below. The container 200 again has a container base 15, a side wall 16, and, on the side of the container 200 opposite the container base 15, a container section 17 which has the container opening 4. The container 200 has an oval shape. The container base is also oval.
[0109] Figures 3a to 3d show the container 200 with the tear-off section 7, i.e., before the first opening. Figure 3e, on the other hand, shows the container 200 after the tear-off section 7 has been removed to expose the dispensing opening.
[0110] As Figures 3d and 3e in particular show, in the illustrated embodiment, the container opening 4 is arranged off-center on the container 200. The container opening 4 is arranged such that the collar 13 and the side wall 16 lie partially in one plane and form a sliding surface 46 inside the container 200. Thus, when the container 200 is tilted, items can slide along the sliding surface 46 from the receiving space 3 through the container opening 4. Figure 3e shows that the dispensing opening 11 is arranged within the space enclosed by the collar 13.
[0111] The container 200 has a first container component 18, which forms the container portion 17, which has the container opening 4. The first container component 18 comprises the closure body 5 with the edge portion 6, the tear-off portion 7, and the web portion 8. The first container component 18 forms an upper closure of the container body 2.
[0112] The container 200 has a second container component 19. The second container component 19 comprises the container base 15. In the illustrated embodiment, the second container component 19 is cup-shaped and has a side wall 16 that is connected to the container base 15. It is possible for the side wall 16 to be formed by sections of the first and second container components 18, 19 or only the first container component 18. The first and second container components 18, 19 are connected by a sealingly designed plug-in connection. The plug-in connection is formed in that the first container component 18 has an insertion section 20 that is inserted into the second container component 19.
[0113] The first and second container components 18, 19 are each manufactured in an integral design as a coherent and one-piece injection-molded part made of plastic.
[0114] The container 200 may have a desiccant chamber (not shown). The desiccant chamber may be arranged on the container section 17 and have a cylindrical wall. The desiccant chamber may be filled with a desiccant, such as silica gel. A side of the desiccant chamber facing the receiving space 3 may comprise a moisture-permeable material.
[0115] The container 200 shown in Figures 3a to 3f has a lid 26 for closing the container opening 4. Figure 3a shows the lid 26 in the closed position, while the lid 26 is shown in the open position in Figures 3b to 3e.
[0116] The lid 26 is movably arranged on the first container component 18.
[0117] The lid 26 is movably mounted on the container section 17. For this purpose, a hinge 27, designed as a film hinge, is provided between the lid 26 and the container section 17. The hinge 27 forms an (imaginary) axis of rotation for the lid 26. The lid 26 can assume an open position and a closed position.
[0118] The lid 26 is designed as a flip-top lid. For this purpose, the lid 26 is connected to the first container component 18 such that the first container component 18 is integrally constructed with the lid 26 as a coherent, one-piece injection-molded plastic part. The lid 26 has a base 28 and a skirt 29 arranged thereon, which, in the closed position of the lid 26, extends in a direction from the base 28 toward the container body 2. The skirt 29 is arranged on the edge of the base 28.
[0119] As shown in particular in Figure 3b, a sealing section 30 is arranged on the base 28, which seals the container opening 4 in the closed position. The sealing section 30 has a sealing collar, which rests against the collar 13 of the container opening 4 when the lid 26 is in the closed position. The base 28 has a projection that forms the sealing collar.
[0120] The container 200 has a child safety lock with a first safety element 31 and a second safety element 32, which can assume a locking position in which the lid 26 cannot be opened, and a release position in which the lid 26 can be opened.
[0121] The first securing element 31 is formed by a portion of the apron 29 and includes a recess 33 arranged in the apron 29. The second securing element 32 is arranged on the container body 2 and has a locking portion 34 that engages in the recess 33 in the locking position.
[0122] The second securing element 32 is movably arranged and movable between the locking position and the release position. The second securing element 32 automatically assumes the locking position, while it must be moved into the release position by pressure. The second securing element 32 can be moved from the locking position to the release position by pressure from the outside to the inside on the actuating surface 35, and the second securing element 32 automatically returns to the locking position without pressure. The second securing element 32 has a web 36 on which the locking section 34 is arranged, wherein the web 36 has a smaller width than the locking section 34.
[0123] The locking portion 34 has an actuating surface 35 on its outer side, and the locking portion 34 can be moved from the locking position to the release position by applying pressure to the actuating surface 35. After the securing elements have been moved to the release position, the cover 26 can be opened.
[0124] As shown in particular in Figure 3c, the container 200 has two of the recesses 33 and two of the locking portions 34, wherein one of the recesses 33 with the associated locking portion 34 is arranged on one side of the container 200 and the other of the recesses 33 with the associated locking portion 34 is arranged on the other, opposite side of the container 200.
[0125] The recess 33 is open on the side facing the container body 2 in the closed position of the lid 26. The recess 33 has a recessed area 37, with the skirt 29 forming a blocking section 38 between the recessed area 37 and an edge of the skirt 29, which enables a positive connection with the locking section 34. The blocking section 38 is formed by a wall section of the skirt 29.
[0126] The recess 33 has a first recess width at an edge of the apron 29 and a second recess width in a section spaced from the edge, which second recess width is greater than the first recess width.
[0127] The locking section 34 has, at least in sections, a curved contour on its edge facing the apron 29.
[0128] As shown in particular in Figure 3a, the locking portion 34 and the recess 33 have a congruent shape. Thus, the skirt 29 and the locking portion 34 form a substantially closed envelope.
[0129] The apron 29 has a pressure surface 39, which moves the second locking element 32 into the release position when the lid 26 is closed. This allows the lid 26 to be closed particularly easily, with the child safety lock engaging.
[0130] Figure 3f shows a sectional view of the container 200 along the sectional axis SS shown in Figure 3e. As shown in Figure 3f, the first and second container components 18, 19 comprise two locking devices 48 that prevent the connection between the first and second container components 18, 19 from becoming loose. Each of the two locking devices 48 has a locking recess 49 and a locking projection 50, wherein the locking projection 50 engages in the locking recess 49 and positively connects the first and second container components 18, 19. The first container component 18 has the locking projections 50. The locking projections 50 are each designed as a locking lug 51. The second container component 19 has the locking recesses 49. The locking recesses 49 each extend over the entire material thickness of the second container component 19.
[0131] Figure 4 shows a perspective detailed view of the tear-off section 7 with the annular tab 10 of the container 200 from Figures 3a-3f, after the tear-off section 7 has been detached from the container 200. In the exemplary embodiment shown in Figure 4, the tear-off section 7 has an elliptical basic shape. The tear-off section 7 can thus form an elliptical dispensing opening. As shown, the tab 10 is connected to the tear-off body 7 in an edge region thereof.
[0132] Figure 5 shows a fourth embodiment of a container 200'. The fourth embodiment of the container 200' predominantly has the features of the above-described third embodiment of the container 200 from Figure 3. Therefore, the same reference numerals are used for parts with the same function. Reference is made to the above description.
[0133] The differences between the container 200' and the container 200 concern the design of the closure body 5. Therefore, only a plan view from above is shown in Figure 5.
[0134] In the embodiment shown in Figure 5, the closure body 5 has a tear-off section 7 and an edge section 6 of the closure body 5, which are designed analogously to the second embodiment of the container 100' from Figure 2. The tear-off section 7 is again smaller than the container opening 4 and also differs in shape. The tear-off section 7 again has a first region 21 and a second region 22, wherein the first width in the first region 21 is smaller than the second width in the second region 22.
[0135] The tear-off section 7 also has a third region 23 with a third width, wherein the tab 10 is arranged on the third region 23.
[0136] Additional or different features are described below.
[0137] A first distance A1 between the first region 21 and the hinge 27 is greater than a second distance A2 between the third region 23 and the hinge 27. As a result, the tab 10 arranged on the third region 23 is arranged closer to the hinge 27 than the first region 21 forming the dispensing opening 11.
[0138] Figure 6 shows a perspective detailed view of the tear-off section 7 of the container 200' from Figure 5, after it has been detached from the container 200' by pulling on the tab 10. In Figure 6, it can be seen in particular that the tear-off section 7 has a first region 21, a second region 22, and a third region 23. The second region 22 is elongated and narrower than the first region 21. The first region 21 of the tear-off section 7 can thus form a dispensing opening. The tab 10 is connected to the tear-off body 7 in the third region 23. The second region 22 connects the first region
[0139] 21 with the third area 23.
[0140] Figure 7 shows a first embodiment of a tool 40 of an injection mold for producing a container. The tool 40 is illustrated using the example of the first container component 18 of the container 200 from Figures 3a to 3d. An injection mold element 45 of the injection mold is also shown. For better understanding, the first container component 18 that can be produced in the injection mold is also shown.
[0141] The injection mold has a cavity that is filled with liquid plastic during the injection molding process to produce the container. The injection mold comprises a tool 40 that is replaceably arranged in the injection mold and the injection mold element 45. For reasons of clarity, the tool 40 and the injection mold element 45 are shown in Figure 7 without the other components of the injection mold that form the remaining sections of the first container component 18. The tool 40 is designed to delimit a surface of the closure body 5. In the illustrated embodiment, this is the outward-facing side of the closure body 5. The injection mold element 45 is designed to delimit a surface of the closure body 5 that is arranged on the side of the closure body 5 facing away from the tool 40. In the illustrated embodiment, this is the inward-facing side of the closure body 5.Furthermore, the injection mold element 45 is designed to delimit at least one further surface of the first container component 18. In the illustrated embodiment, these are the inwardly facing sides of the first container component 18. The tool 40 comprises a core 41 and a shell 42 movable relative thereto. The core 41 is enclosed by the shell 42.
[0142] A cavity 43, shown in dashed lines, is formed between the core 41 and the shell 42 to form the finger-shaped tab 10. The shell 42 has a projection 44 on its end face to form the web section 8. Due to the relative mobility between the core 41 and the shell 42, the core 41 can first be removed from the injection-molded component after the plastic has been introduced and cured, so that the tab 10 can then be demolded from the shell 42. The shell 42 can then be removed.
[0143] Figure 8 shows a schematic perspective view of the tool from Figure 7. Shown in particular is the projection 44 encompassed by the casing 42, which forms a groove in the injection-molded component during the injection molding process, forming the web section. In the illustrated embodiment, the projection 44 has an elliptical configuration, resulting in an elliptical configuration of the tear-off section 7 on the closure body 5 of the container 200.
[0144] Figure 9 shows a second embodiment of a tool 40' of an injection mold for producing the container 200'. An injection mold element 45 is also shown. For clarity, a first container component 18 not belonging to the injection mold is shown. The second embodiment of the tool 40' predominantly has the features of the above-described first embodiment of the tool 40 from Figure 7. Therefore, the same reference numerals are used for parts with the same function. Reference is made to the above description.
[0145] The tool 40' is designed to form the tear-off section 7, as it is designed in the embodiments according to Figures 2 and 5. The tool 40' is illustrated using the example of the first container component 18 of the container 200' from Figure 5. For better understanding, the first container component 18, which is not part of the injection mold, is shown. The injection mold element 45 is designed to delimit a surface of the closure body 5 assigned to the side facing away from the tool 40' and at least one surface of the first container component 18.
[0146] Deviating from the embodiment according to Figures 7 and 8, both the jacket 42' and the core 41' have the projection 44' on their end face to form the web section 8. In this way, the dispensing opening can be made considerably smaller than the container opening and have a different shape. At the same time, a tab can be obtained that is larger than the dispensing opening. The projection 44' extends over the jacket 42' and core 41'. The projection 44' has a shape that corresponds to the outer contour of the tear-off element 7 according to Figures 2 and 5.
[0147] Figure 10 shows a perspective view of the tool 40' from Figure 9. Figure 10 particularly shows the projection 44' encompassed by the jacket 42' and core 41', which forms a groove in the injection-molded component during the injection molding process, which groove forms the web section. The projection 44' is configured such that a configuration of the tear-off section 7 is obtained on the closure body 5 of the container 100', 200', which has a first region 21, a second region 22, and a third region 23.
[0148] With the tools 40, 40' shown in Figures 7 to 10, the opening cross-section of the dispensing opening can be changed during the production of a container manufactured by the injection molding process. This can be achieved by varying the design of the tear-off sections of the containers 200, 200'.
[0149] The method comprises providing the first tool 40 shown in Figures 7 and 8 and the second tool 40' shown in Figures 9 and 10. As described, the projection 44, 44' forming the web section 8 is designed differently in the first tool 40 and the second tool 40', such that the size and shape of the dispensing opening 11 are different for a container 200 produced with the first tool 40 and a container 200' produced with the second tool 40'. Since the first and second tools 40, 40' are interchangeable, the first or second tool 40, 40' can be easily inserted into an injection mold to change the opening cross-section of the dispensing opening 11. Containers 100, 100' as described in Figures 1 and 2 can be produced in the same way using appropriately adapted tools.
