Description

Plastic container with snap lid {PLASTIC CONTAINER WITH SNAP LID}

The present invention relates to a plastic container having a snap lid and a snap element provided at a top edge portion of the container so that the lid can be bitten into the container, wherein the lid snapped into the container has a portion in tight contact with the top edge portion of the container. And a plastic container in which a working area between the container and the lid interacting under such tight contact forms a sealing area.

Plastic containers of this kind are used to transport a variety of goods, especially in the industrial and food sectors, and have proved very effective for this purpose. However, there is still a problem of sufficient leakage safety of plastic containers when carrying liquids or low viscosity materials. This is especially a problem when transporting volatile or important other forms of commodities such as oils, especially mineral oils. In this case, particularly high demands should be placed on the leakage safety of the plastic container, which has not been satisfactorily achieved by conventional plastic containers, and even sufficient lid safety is achieved by providing lids and container edges with matching contours. There have been many attempts to do this. As a result, these goods are usually transported in a metal container. German application publication No. 4422534 discloses a single injection molded edge container in general with a snap lid, whereby the lid is mounted so that the lid can Together with the opening of the container, it is in firm contact with the wall of the container with the circumferential edge of the lid having an inner surface.

It is an object of the present invention to contemplate a plastic container with a snap lid capable of reliably fulfilling the special requirements imposed on leakage safety.

This object is solved by a plastic container having a snap lid, in which the sealing area between the container and the lid has a circumferential seal made of a material having a greater elasticity than the container and the lid, the seal forming the seal. It is integrally molded at at least one interaction site of the container and the lid.

That means that when the lid is in place, an integrally molded circumferential seal that lies tightly between the container and the lid is present in the seal, the seal being more elastic than the elasticity of the lid and / or the drip tray. It is made of a material, especially a rubber material. The seal is thus integrally molded on a container consisting of a drip tray and a lid. In this way, errors caused by inserting the seal by hand can be avoided and the seal is fixed to the lid or the container and even when exposed to external forces, for example when the container falls, the seal It is always located in a fixed manner in the component. The seal is preferably integrally molded by an injection process, for example injection molding, so that seams or the like can be avoided. The seal can be injected into the same mold immediately after the relevant container portion is molded, in particular to maintain low manufacturing and error.

The seal is advantageously molded into the cell with the lid, the width of the lid being, for example, but not limited to, approximately 1.5 to 3 times larger than the wall thickness of the top container edge. The seal can have an essentially horizontal sealing area and can also be contoured, for example U or V shaped. One, two or even more different sealing areas may be provided differently in terms of their contact width, their material thickness or other properties, which may be linear or planar. The sealing regions can be separated from each other crosswise and / or radially or axially.

The seal is advantageously located in a circumferential groove in the lid open towards the edge of the container, which seal can extend over the entire width of the groove and is further fixed against lateral movement. The side flanks of the grooves can preferably surround the inside and outside of the container edge, with or without slight lateral movement, without any limitation.

The seal preferably has adjacent sealing areas at different angles and tight contacts at the edge of the container at different angles. At this end, the seal can have a U, V or L-shaped cross section, in particular another contour, the sealing area can be arranged at the sealing parts facing each other, for example as possible convex surfaces. Sealing regions at different angles may be intended as a single part or as a plurality of parts, ie not in a continuous design, wherein at least one, or preferably all of the seals are integrally molded to the container and / or the lid.

When the container is sealed, the seal is preferably an essentially horizontal portion in tight contact with the top edge of the container edge, and a radially inwardly inclined contact with the interior of the upper container edge and preferably inclined downwards. With a site. The downwardly inclined sealing region may extend essentially vertically or at a constant angle when the container is in a vertical position, and the two sealing regions may enclose an angle of 90 ° to 135 ° or more. . The inclined sealing region thus terminates at the inclined portion and preferably extends in an essentially linear form. The length of the inclined sealing region may be approximately equal to the length of the horizontal sealing region, for example one quarter of the total length. In addition, the container edge preferably has a radially inner bevel or chamber for positioning the horizontal sealing area and the vertical or oblique sealing area. However, other designs are also possible. As a result, forces in the area of the flexible seal, even laterally acting on the seal area, are always absorbed, ensuring a high degree of leakage safety.

The seal may have one or more circumferential sealing ribs projecting towards the container edge, in contact with the container portion, in particular the top edge of the container. The height of the sealing rib may be smaller than the wall thickness of the container. The vessel edge may be planar or one or more circumferential ribs may be provided, and the multiple pairs of ribs may form a groove that is at least partially engaged with one or more sealing ribs. The sealing ribs may be provided at other parts of the sealing part, for example horizontal parts and / or vertical or inclined parts. The cross section of the sealing rib need not be the same as the circumferential groove of the container edge as long as a sufficient sealing effect is achieved. The cross section of the container edge groove may be the same as or smaller than the cross section of the sealing rib so that when the lid is in place, the groove can be completely filled with the flexible sealing rib. The cross section of the groove can also be larger than the cross section of the joining sealing ribs in this case, and in this situation, for example, offsetting of lateral movement for the same purpose can only be achieved by the web. The delimiting webs or edges of the grooves can also be tightly in contact with the seal. If desired, one or more ribs may be provided at the edge of the container that engages the recess provided for this purpose in the flexible seal. In particular, the structures of the sealing and container edges in contact do not coincide or complement each other, so that the convex portions on the seals do not lie in opposite recesses in the container edge, but on the convex portions, eg flank portions, on the container edges. Contact from This results in non-joint linkage that ensures reliable leakage safety. In this situation, the height of the sealing rib is preferably less than the wall thickness of the container, for example, but not limited to, 1/2 to 1/5 or less of the wall thickness.

The container edge may also be provided with at least one rib to seal the container in contact with the plane of the seal. The ribs are preferably high, and when the lid is opened, the ribs at least partially or essentially completely puncture the seal with greater elasticity than the container material.

The seal is preferably such that when a force is applied to the lid or the container in the sealing area, the seal acts simultaneously as a deformation zone so that a height or thickness that avoids deformation of the harder lid and container part when exposed to some force. Have

In order to seal the container when the lid is opened, the horizontal and / or vertical or downward incline of the seal is divided into the partial area or preferably the total surface area (ie of the total radial expansion) of the corresponding contact of the container or lid. Can make flat contact with.

The radially outwardly projecting web may be intended for the radial expansion of the circumferential rib to be less than the thickness of the vessel wall, and may be integrally formed at the outwardly inclined portion of the outer vessel wall adjacent to the top edge of the vessel. . Such ribs can be made of the same material as the container wall and inherently reduce friction when placed on the lid, and these ribs have a second sealing function which is mainly performed by a flexible compressible seal. Two or more circumferential ribs of this kind may also be provided on the outer edge of the container. When the lid is in place, the ribs preferably contact with no movement as well as without any significant pretension, such that the lid is simply located in the sealing area, or is spaced apart with a slight movement, but not limited thereto.

In order to stabilize the sealing area, radially reinforcing ribs are integrally molded on the outside of the container edge, preferably on the side of the snap element facing the top edge of the container. The reinforcing ribs preferably move radially around the container. The reinforcing ribs can also be divided and consist of several reinforcing parts. Alternatively or additionally, one or more additional reinforcing ribs may be integrally molded on the side of the snap element facing away from or towards the top edge of the container. The thickness, ie height and / or width, of the reinforcing ribs may be at half the area of the wall thickness of the container, preferably at or above the wall thickness. By placing the reinforcing ribs near the flexible seal, the sealing area of the container is particularly stabilized. The lid is preferably in contact with the radially outer side of the reinforcing rib with or without pretension so that the force acting on the side of the lid is directly absorbed by the reinforcing rib. For this purpose, the radially outer side of the reinforcing rib may have a flat portion. The space between the reinforcing rib and the snap element may be intended to receive the snap edge of the lid. If necessary, the reinforcing ribs may also be provided inside the container.

Usefully, the snap connection of the lid is also equally effective even after the container has been opened once, ie the snap zone and the seal zone may be partially or in combination with a tamper-safe seal, eg for opening the container. It is not separated by areas of thin material that must be completely removed or folded. The snap element can be provided directly on the top edge of the container or on a distance away from it, for example on an edge projecting outward.

The snap element for attaching the lid is preferably installed on the outer wall of the container, or inside if appropriate.

The lid preferably has a sliding bevel facing outwards, which can be joined on the top edge of or below the lid, preferably in essentially vertical compartments. The sliding bevel may be located directly above the reinforcing rib provided above the snap element on the outer wall of the container and may be located slightly away from it. Although the snap edge preferably extends radially past the protruding portion away from the vessel wall, the sliding bevel is in radial contact with the snap edge of the lid of the outer portion, or extends beyond the snap edge.

The upper edge of the container preferably has a radially outwardly projecting circumferential collar region facing down, on which the snap element is integrally molded. In this situation, the reinforcing ribs integrally molded and outwardly directed on the snap elements may also be integrally molded over the circumferential vessel collar (and thus reinforce it) and / or the circumferential collar region just above the vessel wall. Due to the downward facing collar regions located away from the vessel wall, the snap regions are isolated from the sealing regions with respect to the forces acting on them.

The downwardly facing circumferential collar region is preferably coupled at the top edge of the container, ie at the height of the sealing region or at a distance of several times the wall thickness, for example 1 or 2 times.

The container preferably has a radially outwardly projecting and downward collar region, which is located below the lid when the lid is on the vessel and extends radially over or beyond the lid. This circumferential collar region can be individually molded integrally on the container wall, in which case it can abut the bottom edge of the circumferential collar region with snap edges or can be located away from the bottom edge in terms of height. This circumferential collar region is preferably intended as a continuous collar region for receiving snap elements, ie as a shoulder that is continuous down and out.

A corresponding tamper-safe seal is provided at this site. The bottom edge of the lid may be placed on this collar region with or without pretension, or may exhibit some movement with it, preferably not touching the bottom edge of the lid by hand. This circumferential collar region has a radial constriction for receiving some or all of the bottom edge of the lid.

The circumferential collar region may be strengthened by a vertical rib that may be located inside the collar region and may be connected to an outer wall of the container. The reinforcing ribs preferably have indents or notches in the bottom, whereby the collar region retains some flexibility and acts as a deformation zone.

The lid preferably has a circumferential portion located away from the flexible seal vertically and / or radially and in tight contact with the inner wall of the container when the lid is in place. This sealing area can be made of the same material as the lid. The sealing area can be intended as a rib that protrudes downward or for example a shoulder on the underside of the lid, and if the lid is in place, it can preferably be positioned over the recess in the vessel wall. When the lid is in place, the sealing area can lie on the recess, or can be located away from it, preferably when the additional container is stacked on top or when an external force is applied The bottom of the rib or the bottom of the lid shoulder is placed on the recess of the rib. In such a situation, the lid portion may preferably be firmly in contact with the essentially vertical container area, or above the vertical height, at the height of the snap edge or reinforcement rib provided, preferably on the outside of the container.

In order to increase the reliability of the container seal, a portion projecting upward beyond the bottom edge of the rib may be provided on the inner wall of the container and radially inward with respect to the circumferential rib or web integrally formed inside the lid. . For this purpose, individual protrusions or webs may be provided to spread throughout the circumference. This site is also preferably intended as columnar ribs. The height of this rib, which prevents movement into the inside of the lid rib, is preferably less than, but not limited to, the wall thickness of the container or lid rib. The protruding portion of the container may be positioned in contact with or slightly away from the side of the rib of the lid with or without pretension. In this situation, the ribs of the lid may also be placed in compression between radially adjacent container portions inside and outside.

The shoulder of the container inner wall, located under the shoulder or rib of the container or the like, can be approximately positioned at the height of the snap element or reinforcing rib, or at a distance several times the wall thickness of the container.

In order to stabilize the sealing area, the lid may be provided in close contact with the inner part of the container wall, preferably with at least one radially inner projection which can be integrally molded to the upper part. The protrusion may be an annular, boxed (eg cuboidal, polyhedral) or web shaped design, but is not limited thereto. Internal reinforcing ribs may be provided to stabilize the box or annular projections.

The top portion of the protrusion is usefully located away from, preferably on, the lid portion that is in tight contact with the inner wall of the container, and the contact points in the vertical direction may in fact be speckled or linear. The cross section of the protrusion may be intended in the form of an oblique triangle or rectangle, and the top and / or bottom edge of the side walls of the protrusion may be intended to be inclined downward toward the inside of the container. The radially inner end wall of the protrusion may be vertical or at an angle. The protrusion may be integrally molded on the top edge of the lid. The upper edge of the protrusion is preferably located below the upper edge of the lid, forming the other shoulder. This avoids forming integrally at the height of the sealing area on the interior of the container, which leads to material stress or deformation, for example due to the shrinking process.

In a sealing area such as a side shape on a protrusion such as a protrusion or web, a protrusion toward the center of the lid is usefully intended to avoid most or all of the vertical elongation connecting the surface and the circumferential sealing ribs.

For this purpose, projections extending over a relatively large portion of the circumference, or preferably radial circumferential edges, may be provided inside the lid. In this situation, the side of the protrusion may be located at a radial distance from the circumferential sealing area at the top of the protrusion, such that when looking at the lid from below, it is, for example, approximately trapezoidal or triangular in cross section and facing a wider area therein. A circumferential groove occurs. Said projections, in particular annular, circumferential projections, may also be reinforced with internal ribs, preferably ending at a radial distance from the support ribs or seals in contact with the inner wall of the container, or at a distance from the sealing area of the ribs. Lay on.

In this situation, the upper portion of the protrusion may contact essentially horizontally with the inner edge of the lid, preferably at an angle of less than 15 °, for example 5 °, towards the interior of the container.

The lid surface blocking the opening of the container can be positioned below or at the same height as the inner sealing area, preferably below the snap edge or at the same height.

A spout can be mounted to the lid and is preferably located approximately one quarter diameter of the lid surface area to allow practical operation of the drip tray when the liquid is poured.

Embodiments of the invention are described below on the basis of the drawings. The figure shows the following.

1 shows an injection molded plastic drip tray 1 with a lid 2 snapped on, with the top edge 4 of the outer wall 3 of the drip tray being installed in a flat area. The upper edge 4 is connected to a circumferentially radially protruding collar 5, on which the outwardly protruding snap element formed as a snap edge 6 is integrally formed, so that the lid has a projection of the hook. It is joined from below by the circumferential snap edges 7. The areas of the drip tray and lid that snap together are essentially horizontal and have no rounded outer edges, in particular a fixed snap connection is provided by the interlocking connection. The snap edges of the drip tray and lid can also be bent downward toward the outside, enhancing the linkage.

The region of the lid (2) which engages the top edge (4) of the drip tray is in the shape of a groove or channel, in which the outer flank (8) of the groove (34) has two circumferential ribs (9) perpendicular to the drip tray and It is in contact with the side. The radial elongation of the ribs 9 is considerably smaller than the wall thickness of the drip tray, in this case approximately one third. Due to the rounded top edge of the ribs 9 and the small width of the ribs, the lid can be easily pushed over the drip tray and even very tightly at the edge of the drip tray. Here, the ribs 9 are located at the height of the sealing area 12 of the seal, and even in the absence of these ribs the lid can be placed on the outer wall of the drip tray at this high position with little or virtually no pretension.

The seal made of elastic and compressible rubber material is injection molded as a single piece to the horizontal base of the groove of the lid and the radially adjacent inner flank 10. In order to improve the adhesion of the material, the contact area and the groove base of the rubber seal are provided with suitable altitude and settlement. The sealing region 12 associated with the inner groove flank 10 is at an angle to the vertical line, here at an angle of approximately 20 °, which angle is also not limited to this and may be at a value between 5 and 45 °. . When snapping and opening the lid, the sealing area 12 of the seal 11 lies in a downwardly inclined bevel 13, which is adjacent to the inside of the upper edge 4 of the drip tray (FIGS. 2, 3). The inclination is not limited to this, but coincides with the inclination of the contact portion of the sealing region 12 of the sealing portion. As a result of the special design of the seal, the drip tray is tightly sealed even when a strong force is applied to the edge. The lid area surrounding the sealing area 12 of the seal has also an oblique design inside.

The circumferential collar 5 of the drip tray is joined at the height of the upper edge 4 so that the cavity 14 delimited by the collar 5 extends close to the upper edge, ie to the wall thickness. The upper edge 4 region of the drip tray is thus designed as a U-shaped circumferential contour.

The intrinsic vertical leg of the U-shaped upper edge 4 is shifted outwardly by the bevel 15 at an angle of approximately 30 ° with respect to the vertical line, forming a stepped shoulder. The snap edge 6 is integrally molded under this shoulder and the reinforcement edge 16 of the radial circumference is integrally molded between the snap edge and the shoulder, and in this embodiment, at the height of the shoulder, the snap edge ( And 6) are adjacent to the outside and have a corresponding width, ie vertical extension. The bottom edge of the reinforcing edge 16 is designed to coincide with the bottom edge of the snap edge 6 so that the snap edge 7 of the lid can be engaged in a groove located between the edges 6 and 16, At this end the upper edge of the snap edge 6 is also inclined outward. When fully snapped open, the edges of the lid lie against the outer edges of the snap edge (6), the reinforcement edge (16) and the two ribs (9), the sliding bevel (17) and the bevel ( 15) There is a slight gap in between. A sliding bevel 17 may also be located above the bottom edge of the lid rim surrounding the top edge of the container, such that a web protruding down towards the bevel 15 is formed, which is also bevel 15 or essentially horizontal It can be placed in a zone.

The circumferential collar 5 has a circumferential shoulder 18 below the snap edge 7 protruding away from the snap edge 7 below the outer edge of the lid 2, the snap edge 7 being free. It can be placed under the tension on the shoulder 18, or there can be a gap between the snap edge and the shoulder. The shoulder 18 has a tamper-proof seal 19 which, after removing it, can hold the snap edge 7 by hand from below and remove the lid. Also, several tear-off taps may be provided over or adjacent to a very large portion of the drip circumference. If necessary, a tamper-proof seal can be attached to the snap edge 7. Wherein the lid region between the groove and the snap-edge receiving the seal is preferably free of significantly thin material, so that high stability in the region of the lid between the snap connection and the seal 11 or in the drip tray 1, and Therefore, it is important to ensure high leakage safety.

The lid has a circumferential portion 20a away from the seal 11, which has a circumferential sealing rib 20 therein with respect to the seal 11, the circumferential sealing rib of the face thereof. Tightly contact the inner wall of the drip tray along a part. In this embodiment the sealing area is formed by the bottom end of the rib and is provided approximately at the height of the snap edge or the reinforcement edge 16. The rib 20, which projects essentially vertically downward, is located at the height of the shoulder 21, which protrudes inwardly of the inner wall of the drip tray, and at some vertical distance apart. If some vertical pressure is applied to the lid, the rib 20 is placed in the indent 21. If the sealing function of the ribs is not needed, a downward facing similar web of individual webs may also be provided as a substitute. The indentation 21 is internally delimited by the circumferential ridge 22, instead an individual protrusion may also be provided, the ridge 22 extending above the bottom edge of the rib 20 and being ribbed. Prevent the 20 from moving inwards. The rib 20 can also be accommodated in indentation between the ridge 22 and the adjacent outer wall area of the drip tray. The sealing area formed in the rib 20 (see FIG. 2) is slightly oblique and dimensioned outwardly so that the bottom edge 35 is radially outside the inner wall of the drip tray when the lid is removed. In this case, the thickness of the bottom edge is approximately coincident with the rib thickness, preferably exceeding one quarter of the thickness, and here is slightly tapered. As a result, constant radially pretensioned contact with the inner wall of the container when the lid is opened. The protrusion when the lid is removed is smaller than the rib thickness here and is approximately 1/4 of the bottom edge thickness.

The radial edge 23, which is inclined slightly downwards inwardly, is integrally molded in the ribs 20 above the sealing area and is essentially vertical at the inwardly facing bevel 24 or at a location with a wider edge. The phosphorus wall portion 25 is integrally molded at the portion that transitions to the horizontal lid portion 26. The lid portion 26 is located below the snap edge 6 and, as shown, its outer diameter is sized to allow stacking of the drip trays. As a result, a projection having a triangular cross section integrally formed on the trapezoidal groove is opened toward the bottom.

In order to transmit enhanced force and at the same time stack the lidless drip trays together, the outer wall 3 of the drip tray has a tapered shape or has an angle of less than 3 °, preferably 2 °, relative to the outside Angle is possible. The distance between the wall 25 side protruding toward the center of the drip tray and the outer wall 27 opposite the drip tray is less than 2 mm so that the force generated when the drip trays with lids are stacked can be well absorbed in the edge region. , It is possible to move slightly at a distance of 1 mm.

As shown in the enlarged view of FIGS. 2 and 3, two circumferential ribs 36 are mounted on the top edge 4 of the drip collar, which engages the teeth on the bottom of the seal 11, The ribs 37 protruding below some of the teeth of the seal come into contact with the ribs 36 on the top edge of the drip tray, for example in the flank area, preventing lateral movement of the ribs 37, some of them In the groove formed in between, or outside of the upper edge 4, it is brought into contact with the side rib 36. Due to the inconsistent design of the two structures, the drip tray has high leakage stability.

As further shown by the figures, a vertical reinforcing rib 38 moving perpendicular to the outer wall is provided in a cavity 14 having a recess 33 opening towards the bottom, the tip of which is a drip tray. Is offset toward the outer wall of the.

As shown in FIG. 4, there are segments 28, 29 having different radial widths on the radial edge 23 of the lid, located inside the drip wall 3, resulting in an effective reinforcement, The force on the sealing area of the sealing portion 11 or the rib 20 is absorbed. According to an embodiment, the circumferential extension of segments 28 and 29 is a multiple of the segment width. Thus, the projection comprising the vertical wall 25 and the segment 29 has a box shape. The bevel 24 and the vertical wall 25 are at the same distance from the longitudinal axis of the drip tray, and the portion 30 which determines the boundary of the bevel 24 on the side slopes towards the circumference of the lid. A sealable spout located about one quarter of the diameter of the drip tray is also located at the central portion 26 of the lid.

As shown in the lamination diagram shown in FIG. 5, the bottom edge of the snap edge 7 of the lid lies on the sliding bevel 17, and the bottom edge 35 of the sealing rib 20 holds the seal 11. It is on the horizontal leg 31 of the supporting groove 34. The bottom edge of the box-shaped protrusion 32 may, as a rule or in addition, rest on the top edge of the protrusion below the lid.
