Description

Plastic container with snap-on lid

The invention relates to a plastic container comprising a snap-on lid and a latch provided in the upper edge region of the container for snap-fitting the lid, wherein the lid surrounds the edge of the container on the upper side and the outer side and rests in a sealing manner on the edge of the container.

Such plastic containers are used especially in the industrial and food sectors for transporting various goods and have proven to be very reliable. However, when transporting liquids or low-viscosity materials, there is still the problem of whether the plastic container has sufficient airtightness. This problem occurs especially when transporting volatile and otherwise dangerous goods, such as oils, especially mineral oils. In these cases, particularly high demands are placed on the tightness of the plastic container, which in hitherto known plastic containers, despite numerous attempts to obtain a sufficient tightness by suitable shaping of the container rim and lid, But still not satisfactorily achieved. Therefore, these goods are mostly transported in sheet metal containers.

The object of the present invention is to create a plastic container with a snap-on lid which meets the special demands placed on tightness.

This object is achieved by a plastic container with a snap-on lid, wherein the sealing area is provided with an integrally formed annular seal, which is tightly positioned between the container and the lid when the lid is fitted, where the seal Made of a material more elastic than the lid and/or bucket, especially rubber material. The seal is thus integrally formed on the bucket consisting of container and lid. In this way, possible errors during manual insertion of the seal are avoided and the seal is successfully secured to the lid or container so that it remains in place even when forces are applied, such as when the container is dropped on this component. The seal is preferably injection-molded, for example injection-molded, in order to avoid glued spots or similar measures. The injection molding of the seal can be completed in the same mold directly after the related container components are formed, and the processing and fitting errors can be kept extremely small.

Advantageously, the seal is formed on the lid, in which case the width dimension of the seal can be designed to be larger than the wall thickness of the upper edge of the container, for example about 1.5 to 3 times it, but not limited thereto. The seals can have a substantially horizontally extending sealing zone, which can also be shaped, for example U-shaped or V-shaped. One or also two or more different sealing regions can be provided, which can differ with regard to their contact width, which can each be linear or planar, their material thickness or other properties. The sealing regions can transition into one another and/or be at a radial or axial distance from one another.

Advantageously, the seal is seated in an annular groove of the lid that is open towards the edge of the container, where the seal can extend over the entire width of the groove and thereby additionally prevent lateral movement thereof. The side walls of the groove may surround the container rim on the inside and on the outside, preferably with little or no side play, respectively, but are not limited thereto.

The seal preferably has two adjacent sealing regions, which can have different inclinations and can bear sealingly against regions of the container edge with different inclinations. For this purpose, the seals can in particular have a U, V or L-shaped cross-section or other profile, where the sealing zone can be provided in the region where the seals face each other, but also, if necessary, for example in a convex region middle. The sealing areas of different inclinations can be designed integrally with each other or divided into several parts, i.e. not continuous, in which case one or more, preferably all segments of the seal are integrally formed on the container and / or cover.

Preferably, in the closed state of the container, the seal has a substantially horizontal region, which can be tightly abutted against the upper edge of the container rim, and a radially inward region, which is preferably The ground is inclined downward and can be closely attached to the inner side of the upper edge of the container. When the container is in an upright position, the downwardly sloping area of the sealing member can extend substantially vertically or obliquely with an inclination. Here, the two sealing areas can have an included angle of 90°-135° or more. Thus, the inclined sealing zone ends in the beveled zone and preferably extends substantially rectilinearly. The length of the inclined sealing area may be substantially equal to the length of the uneven area of the seal, for example a quarter of the length of the horizontal sealing area to its full length or longer. Preferably, the container edge also has a horizontal sealing area and a radially inward bevel or chamfer for contact with the vertical or oblique area of the sealing element, but other designs are also possible. Thus, even if lateral forces act on the sealing area, these forces are always absorbed in the area of the elastic seal, thus ensuring a high level of reliability against leaks.

The seal can have one or more annular sealing ribs protruding towards the edge of the container, which abut against a region of the container, in particular the upper edge of the container. The height of the sealing rib can be smaller than the wall thickness of the container. The container rim can be flat or provided with one or more annular ribs which form in pairs a groove into which the one or more sealing ribs are at least partially inserted. The sealing ribs can be provided in different regions of the seal, for example in horizontal and/or vertical or obliquely arranged regions. The cross-section of the sealing rib is not necessarily consistent with the annular groove on the edge of the container, as long as a sufficient sealing effect is obtained. The cross-section of the groove at the edge of the container can be equal to or smaller than that of the sealing rib, so that when the lid is put on, the groove is completely filled with the elastic sealing rib. The cross-section of the groove can also be larger than the sealing rib to be inserted, in which case, for example, the requirement to prevent lateral movement of the seal can also be met only by acting as a crosspiece. The ledge or edge delimiting the groove can likewise bear tightly against the seal. Optionally, one or more ribs can also be provided on the edge of the container, which engage in recesses provided for this purpose by the elastic seal. In particular, the mutual abutment of the seal and the container rim may be incompatible or non-complementary, so that the protrusions of the seal are not positioned opposite the recesses of the container rim, but are in contact with the protrusions of the container rim, which e.g. In the sidewall area of the container edge. The result is a non-uniform engagement which ensures a good and reliable seal. Here, the height of the sealing rib is preferably smaller than the wall thickness of the container, for example, 1/2 to 1/5 or less of the wall thickness, but not limited thereto.

The edge of the container can also be provided with at least one rib for the sealing of the container, which abuts against a flat region of the seal. The rib preferably has such a height that when the lid is closed, the rib is at least partially or substantially completely embedded in the seal which is more elastic than the material of the container.

The seal preferably has such a height and thickness that, when stressed in the sealing area on the container or lid, the seal simultaneously acts as a deformation zone, so that a rigid lid or lid is avoided under certain forces. Deformation of the container area.

The region of the seal extending downwards horizontally and/or vertically or obliquely, when the lid is put on, can lie against the container or the lid in a straight, preferably all-round way, that is to say along the entire radial dimension of the region, in order to seal the container on the corresponding docking area.

Radially outwardly protruding webs can be formed on the region of the outer wall of the container adjacent to the upper edge of the container and slope outwards, which can be designed as annular ribs whose radial dimension is smaller than the wall thickness of the container. These webs can be made of the same material as the container wall and serve primarily to reduce friction when closing the lid, where they only have a secondary sealing function, which is mainly performed by the elastic and compressible seal. It is also possible to add two or more such annular webs to the edge of the container. When the lid is put on, these webs preferably bear against the lid without gaps but without significant pretension, so that the lid is positioned exactly in the sealing area; or are spaced apart with a slight gap, but are not limited thereto. .

In order to stabilize the sealing area, a radially protruding rib is preferably formed on the outer container edge, on the side of the latch facing the upper edge of the container. The reinforcing rib preferably extends radially around the container, it can also be segmented and consist of several reinforcing regions. As an alternative or in addition, one or more further reinforcing ribs can be formed on the side of the latch facing the upper edge of the container or facing away from the upper edge of the container. The thickness, ie height and/or width, of the reinforcing ribs can be in the range of half the wall thickness of the container, preferably in the range of this wall thickness or exceed this wall thickness. By arranging the reinforcing rib adjacent to the elastic seal, the sealing region of the container is rendered particularly stable. Preferably, the cover bears against the radially outer end of the reinforcing rib with or without pretension, so that forces acting on the cover from the side are directly absorbed by the reinforcing rib. For this purpose, the radially outer end of the reinforcing rib can have a flat region. The spacing between the reinforcing ribs and the locking buckle or between the reinforcing ribs can be designed so that it can snap into the locking buckle edge of the cover. If necessary, reinforcing ribs can also be provided on the inner side of the container.

Preferably, the latch of the lid remains equally effective after the container has been opened once, that is to say that the latching and sealing areas are not damaged by material weakening, which is used, for example, as the original closure means and in the original closure. That part of the device whose lid is partially or completely removed or turned over in order to open the container. The catch can be provided directly on the upper edge of the container or at a distance therefrom, for example also on an outwardly protruding edge.

The catches for securing the lid are preferably provided on the outer wall of the container, but can also be provided on the inside if necessary.

Preferably, the cover has an outwardly pointing sliding bevel, which can be attached to the upper edge of the cover or to a region of the cover below the upper edge, preferably to a substantially vertical section. The sliding slope can be arranged directly above the reinforcing rib with a slight distance therefrom, and the reinforcing rib is arranged above the buckle on the outer wall of the container. The sliding bevel can end radially outwards flush with or protrude beyond the latching edge of the lid, preferably it extends radially outwards as far as the region protruding outwards from the container wall.

The upper edge of the container preferably has a radially outwardly extending and downwardly extending annular edge region, on which a lock is formed. In this case, a reinforcing rib formed on the latch pointing outwards can likewise be formed on the annular container rim (thus likewise reinforcing the container rim) and/or directly above the annular edge region on the container wall. By means of this downwardly extending edge region spaced apart from the container wall, the locking region is decoupled from the sealing region in terms of force.

Preferably, the downwardly extending annular edge zone adjoins the upper edge of the container, that is to say at the level of the sealing zone or at a distance of several wall thicknesses, for example one or two wall thicknesses, but not subject to this restriction.

The container preferably has a radially outwardly projecting and downwardly extending edge region which is arranged below the cap which has been placed on the container and which extends radially up to or beyond the cap. This annular edge region can be formed separately on the container wall, and here it is flush with the lower edge of the annular edge region provided with the locking edge or at a distance from this edge region in height. Preferably, this annular edge region is designed as a continuation of the latched edge region, that is to say as a step running downwards and outwards. A corresponding original closure can be provided in this area. The lower edge of the cover can be placed on this edge region with or without pretension, or preferably with a small gap relative to this edge region in such a way that the lower edge of the cover cannot be grasped from below by hand. Edge. This annular edge region can have a radial constriction for partially or completely receiving the lower edge of the cover.

One or more annular edge regions can be reinforced by vertically extending ribs, which can be added to the inside of the edge region and can be connected to the outer wall of the container. These ribs preferably have a groove or notch downwards, so that the edge region remains somewhat elastic and can act as a deformation zone.

Preferably, the lid has an annular region at a vertical and/or radial distance from the elastic seal, which bears tightly against the inner wall of the container when the lid is fitted. This sealing area can be made of the same material as the cover. This sealing area can be designed, for example, as a downwardly extending rib or as a step on the underside of the lid and preferably lies above a step in the container wall when the lid is closed. The sealing area can be placed on the step after the lid is added, but it can also preferably be spaced from the step in such a way that when other containers are stacked or when external forces are applied, the rib of the lid Or the lower end of the step is just supported on the step of container. Here, this area of the cover can be linear or along a vertical height. Closely abutting against a preferably substantially vertically extending container region, which is preferably at the level of a reinforcing rib or snap edge provided on the outside of the container.

In order to improve the reliability of the sealing of the container, on the inner wall of the container, radially located in the inside of the tab-shaped or annular rib formed on the inner side of the cover, a rib protruding upward beyond the lower edge of the rib can be provided. area. For this purpose, projections or crosspieces distributed one by one along the circumference can be provided, preferably this area is likewise designed as an annular rib. The height of the rib to prevent the rib on the lid from moving inward is preferably, but not limited to, less than the wall thickness of the container or the rib. This upwardly protruding region of the container rests laterally against the ribs of the lid at slight intervals, with or without pretension. Here, too, the ribs of the cover can be arranged with a press fit between the container regions that form the inner and outer boundaries in the radial direction.

The step on the inside of the container below the rib or step on the lid or the like may be located approximately at the level of the latch or reinforcing rib, or at a distance of one or a few container wall thicknesses.

In order to stabilize the sealing zone, the lid can preferably have at least one radially inwardly projecting projection in the region radially directly inside the container wall, which can be formed on the upper side of the lid. One or more protrusions can, for example, be designed as rings or boxes (for example cuboids or prisms) or webs, but are not limited thereto. In order to stabilize box-shaped or ring-shaped protrusions, reinforcing ribs can be provided on the inside.

Advantageously, the upper side of the one or more protrusions is preferably at a certain distance above from the area of the lid which rests closely on the inner wall of the container, where the contact points in the vertical direction may actually be points or lines shape. The cross-section of the protrusion can, for example, be designed in the form of a scalene triangle or a quadrilateral, wherein the upper and/or lower edge of the side wall of the protrusion can be designed to slope down towards the interior of the container. The radially inner end wall of the protrusion can extend vertically or obliquely. These protrusions may be formed at the upper edge of the cover. Advantageously, the upper edge of the protrusion is arranged below the upper edge of the cover, thereby forming a further step. This avoids forming at the height of the sealing zone on the inside of the container, which would otherwise lead to material stresses or shape changes, for example as a result of shrinking processes.

Advantageously, the projection towards the center of the cover is designed such that a connection surface extending perpendicularly to the annular sealing bead in its sealing region, for example in the form of a raised side or a ledge-like projection, is also largely or completely avoided. For this purpose, a projection extending over a larger circumferential extent can be provided, or preferably a radial annular edge can be provided on the inner side of the cover. Here, the side faces of the protrusions can be arranged at a radial distance from the annular sealing zone next to the upper side of the protrusions, so that when the cover is viewed from the underside, a ring with, for example, approximately trapezoidal or triangular cross-section and expanding downwards is formed. groove. If necessary, the projections, especially annular projections, can also be reinforced by internal ribs, which preferably end at a certain radial distance from the sealing ribs or supporting ribs which rest on the inner wall of the container , or arranged at a distance from the sealing area of the sealing rib on the protrusion.

The upper side of the protrusion can be arranged substantially horizontally on the lid inner edge, preferably sloping down towards the container interior with a slope of less than 15°, for example 5°.

The surface of the lid closing off the mouth of the container can be arranged at or below the level of the inner sealing zone, preferably at or below the level of the snap edge.

A pouring spout may be provided on the lid, preferably about a quarter of the diameter of the lid surface, so that the container can be easily manipulated when pouring out the liquid.

The invention is explained below by way of example with the aid of the figures. in:

Fig. 1 band cover and has stacked another container partial sectional view according to the container of the present invention;

Figure 2 is a detailed view of the container with a lid according to Figure 1;

Fig. 3 is by the detailed view of the container section of Fig. 1;

Figure 4 is a top view of the container with a lid according to Figure 1; and

FIG. 5 is a schematic diagram of the stacking of the lids according to FIG. 1 .

FIG. 1 shows an injection-molded plastic bucket 1 with a snap-on lid 2, wherein a flattened area is provided on the upper edge 4 of the outer wall 3 that ends the bucket. An annular and radially outwardly protruding edge 5 is connected to the upper edge 4, on which an outwardly protruding locking edge 6 is formed, and the annular locking edge 7 of the cover protrudes in the form of a hook. The block buckles the buckle edge 6 from below. The region where the lid and the bucket snap into each other is designed as an essentially horizontal and rough outer edge, so that a particularly secure snap-in connection is provided by the formed hook connection. The locking sides of the barrel and lid can also be sloped outwards and downwards if necessary, thereby strengthening the hook connection.

The region of the cover 2 which is matched to the upper edge 4 of the bucket is designed as a groove or groove, wherein the outer sides of the groove 34 bear laterally against two vertically spaced ring webs 9 of the bucket. The radial dimension of the web 9 is significantly smaller than the wall thickness of the barrel, here approximately one-third of this wall thickness. Due to the rounded upper edge of the web 9 and the relatively small width of the web, the lid can be easily slipped onto the bucket even if the lid is pressed laterally against the edge of the bucket. Here, the webs 9 are provided at the level of the part 12 of the seal, in which case even if these webs are missing, the lid can rest against the barrel at this height with little or practically no pretension on the outer wall.

A seal made of an elastic and compressible rubber material is integrally injection-moulded on the horizontal groove base of the cover and on the side wall 10 delimiting the radial inner side. In order to improve the material connection, the abutment area of the groove bottom and the rubber seal on the groove bottom is designed with identical protrusions and depressions. The sealing area 12 associated with the inner groove side wall 10 is arranged inclined relative to the vertical, here at an angle of about 20°, which angle can also assume values between 5° and 45°, but is not restricted thereto. In the locked state of the cover, the inclined part 12 of the sealing member 11 abuts on the inclined surface 13 that is connected to the inner end of the upper edge 4 of the bucket and slopes down inwardly (also see Fig. 2, 3), the slope of the inclined surface 13 is consistent with The inclination of the abutment surfaces of the seal part 12 is uniform, but not limited thereto. With this special design of the seal, a reliable sealing of the drum is guaranteed even when high forces are applied to the drum edge. The part of the cover that surrounds the seal part 12 radially on the inside is also designed to be inclined.

The annular edge 5 of the bucket is connected at the level of the upper edge 4, so that the cavity 14 bounded by the edge 5 extends as far as the vicinity of the upper edge, that is to say up to approximately one wall thickness. The region of the upper edge 4 of the bucket thus also forms a U-shaped annular profile.

The substantially vertical side of the U-shaped upper edge 4 transitions outwards to an inclined surface 15, and the included angle of the inclined surface 15 with respect to the horizontal plane is about 30°, thereby forming a stepped step. A locking edge 6 is formed below the step, and between the locking edge and the step, at the height of the step, a radial annular reinforcing rib 16 is formed. In this example, the reinforcing rib 16 is It ends at the height of the locking edge 6 and has the same width as the locking edge 6 , ie, the same vertical dimension. The lower edge of the reinforcing rib 16 is designed to be consistent with the lower edge of the locking edge 6, so the locking edge 7 of the cover can also be inserted into the groove between the edge 6 and the reinforcing rib 16. For this reason, the upper edge of the locking edge 6 also slopes outwards. Thus, in the fully locked state, the edge of the cover bears against the locking edge and the outer edge of the reinforcing rib 16 as well as on the two webs 9 , wherein between the bevel 15 and the sliding bevel 17 of the cover located above this bevel 15 There is a small gap between them. The sliding bevel 17 can also be arranged above the lower edge of the lid edge surrounding the upper edge of the container, thereby forming a tab protruding downwards towards the bevel 15, which can also rest against the bevel 15 or the bevel if necessary. on a substantially horizontally extending portion of the

The annular edge 5 has a ring-shaped step 18 below the locking edge 7, which extends from the locking edge 7 to the outer edge of the cover 2, where the locking edge 7 can be placed under the condition of a pre-tensioning force. On the step 18, or also can leave a gap between the buckle edge and the step. The step 18 has an original closing device 19, after it has been removed, the snap edge 7 can be grasped by hand from below and the lid can be opened. It is also possible to provide a plurality of pull tabs which are juxtaposed or extend along a larger circumferential extent of the barrel. The original closure device can also be contained on the buckle edge 7 if necessary. It should be pointed out here that preferably there is no significant material weakening of the lid area between the groove for receiving the seal and the snap edge, so that between the snap-in connection and the seal 11 or the area of the lid inside the barrel 1 The space guarantees a high degree of stability and thus also a high degree of tightness.

Inside the seal 11, there is a ring-shaped sealing rib 20, which is only closely attached to the inner wall of the barrel along a part of its height. Be located at the height of the reinforcing rib 16 or the buckle edge. The rib 20 protruding substantially vertically downwards is arranged at the height of the step 21 protruding inwards of the barrel inner wall, and has a small vertical distance from this step 21. The ribs 20 bear against the steps 21 when a small vertical pressure is applied to the cover. If the sealing function of the sealing rib is superfluous, then, as an alternative, it is also possible to provide downward tab-like protrusions one by one. The step 21 is inwardly bounded by an annular edge 22, instead of the edge 22, each protrusion can also be used. Here, the edge 22 protrudes upwards beyond the lower edge of the sealing rib 20, and prevents the sealing rib 20 from moving upwards. movement within. The sealing bead 20 can also be fitted with a press fit between the rim 22 and the wall region of the bucket as the outer boundary. The sealing area of the sealing rib 20 is formed in such a way (see FIG. 2 ) that the rib 20 is slightly inclined outwards and is dimensioned so that its lower edge 35 will lie radially in the barrel when the lid is removed. Outside the inner wall. Here, the thickness of the lower edge is approximately equal to the thickness of the sealing rib, preferably greater than 1/4 of the thickness of the rib, in which case it is slightly tapered. Therefore, when the lid is closed, it always abuts against the inner wall of the container with a radial preload. The overhang when the cover is removed is here less than the thickness of the sealing rib and approximately 1/4 of the thickness of the lower edge.

On the sealing rib 20 above the sealing area, a slightly inwardly beveling annular edge 23 is formed radially inwardly, from which an inwardly directed bevel 24 is formed sectionally from this edge 23 or at the edge of the widened annular edge. The width positions form essentially vertical wall regions 25 , which each transition into horizontal cover regions 26 . This area 26 is provided below the latching edge 6, where, as shown, its outer diameter is dimensioned to allow the drums to be stacked. Protrusions with a triangular cross-section are thus formed, which are formed on a trapezoidal downwardly opening groove.

In order to improve the transmission of force while the barrels can be stacked on top of each other without a lid. The outer wall 3 of the bucket has a conicity or slope to the outside of less than 3°, preferably 2°, here also a smaller slope is possible. In addition, in order to better bear the force in the edge area when the buckets with lids are stacked, the distance between the side of the raised wall 25 facing the center of the bucket and the outer wall 26 of the bucket in the opposite position is designed to be only Small gaps, for example a pitch of less than 2 mm, preferably 1 mm.

As can be seen from the enlarged views of FIGS. 2 and 3 , the upper edge 4 of the bucket rim is provided with two annular ribs 36 which mesh with the teeth on the underside of the seal 11 , where the teeth of the seal protrude downwards. The ribs 37 are partly in contact with the ribs 36 of the upper edge of the bucket, for example in their side areas (thus preventing lateral movement of the ribs 37); partly next to the ribs 36 in the groove formed between the ribs 36 ; or beyond the container edge 4 outside the rib 36 . By adopting the design that these two structures are not completely consistent, the tightness of the barrel height can be achieved.

It can also be seen from the accompanying drawings that vertical reinforcing ribs 38 protruding vertically relative to the outer wall are set in the cavity 14, and they have a gap 33 that opens downwards. Here, the peak of the gap is set toward the barrel. The direction of the outer wall is misaligned.

As shown in Figure 4, the annular edge 23 on the inside of the barrel wall 3 is provided with sections 28, 29 of different radial widths, thus constituting an effective reinforcing profile for absorbing the sealing action of the sealing rib 20. The force on the zone or on the seal 11. According to the present exemplary embodiment, the circumferential dimension of the segments 28 , 29 is a multiple of their width. Therefore, these protrusions are designed in a box shape. The bevel 24 and the vertical wall region 25 end at the same distance from the main barrel axis, wherein the region 30 which laterally delimits the bevel 24 runs obliquely with respect to the circumference of the lid. In addition, a closable pouring spout is provided in the central region 26 of the lid, which is arranged at approximately a quarter of the barrel diameter.

As can be seen from the stacking schematic diagram shown in FIG. 5 , the lower edge of the locking edge 7 of the cover is placed on the sliding slope 17 , and the lower edge 35 of the sealing rib 20 is placed at the level of the groove 34 for accommodating the seal 11 on side 31. As an alternative or in addition, the lower edge 32 of the box-shaped protrusion can also rest on the upper edge of the protrusion of the lid lying below it.
