Definitions

  • the present invention relates to a plastic bucket and lid with a collar-shaped spacer and concealed clamp closure consisting of a bucket or container which has an outwardly projecting collar and a sealing lip axially pointing away from the bucket opening, and a lid with an outer centering web and a sealing groove which of the Outer web, top flange and inner web is formed, with the centering web surrounding the sealing groove with the outer web, the top flange and the inner web in a protective manner.
  • the bucket and the lid have an area with the same diameter and a certain design, so that, among other things. a protective space is formed which protects the sealing lip in the case of pails stacked one inside the other and other advantages in stacking, storage, emptying of the containers and the like can be achieved.
  • Plastic buckets are used in many areas of industry and trade.
  • the automation and development of fully automatic production lines with control stations also places special demands on the packaging - such as buckets and lids.
  • a bucket is known from utility model application 8335866, which can be centered on one another in the stack and used in an aligned manner in robot magazines.
  • centering webs enable good magazine guidance.
  • the disadvantage of such packaging buckets and lids is the free accessibility of the bottom latching segments of the lid and bucket. The pallet stack moves frequently during transport and the lids are pushed off.
  • Another disadvantage is the empty stacked buckets because the spaces between the bucket collars require special mechanisms for lifting and fixing the carrying handle.
  • these cavities as dirt corners - especially in the food sector - are disadvantageous. Since mostly high-sealing closures are required, damage to the edge of the bucket and thus leaks are always possible with stacked buckets. The spacers of the conventional buckets adversely press on the important closure parts.
  • a plastic bucket with a lid which has a U-shaped neck collar with a transverse section at the periphery of its opening.
  • the lid In the closed state, the lid extends with its circumferential U-shaped edge over the bucket edge opening, the outer lid edge being radially extended outwards. This radial extension is designed in the U-shaped protrude upward collar and snap into a snap groove when closed.
  • the present invention is based on a bucket and lid, which the above. Avoids disadvantages, and has improved properties compared to the known closable buckets. However, once you change a feature on buckets with a closable lid to achieve improvements, disadvantages often occur with other properties or parts, so that a combination of features often has to be changed in order to reduce or avoid disadvantages in other places.
  • a plastic bucket or plastic container which has an outwardly projecting collar (5) and a sealing lip (3) axially pointing away from the bucket opening and an adapted cover (20) with an outer centering web (26) and has a sealing groove (23) which is formed by the outer web (25), head flange (24) and inner web (22), the centering web (26) with the outer web (25), the head flange (24) and the inner web (22 ) protects the sealing groove (23).
  • the collar (5) is designed like a hollow cylinder with the same circumferential circumference or as a closed cylinder and has the same diameter with the centering web (26) of the cover (20) in the closed state and forms a common outer cylindrical surface (X).
  • the bucket has a centering shoulder (4) and a pressure flange (2) and the collar (5) forms a protective space (6) with the bucket wall (1), the sealing lip (3) and the centering shoulder (4) when the buckets are stacked one inside the other are covered and protected.
  • the lid of the invention has the same outer diameter with the bucket collar and is flush. As a result, there are no starting points that the lid could be accidentally pushed off. Bucket and lid form a smooth cylindrical outer surface. The outer contours of the bucket and lid are therefore difficult or impossible to open without additional handling or tools.
  • the diameter of the circumferential sealing lip (3) arranged on the upper edge of the container is smaller than the inner diameter of the centering web (26) of the lid and the length L 1 of the centering shoulder (4) is greater than the length L 2 of the sealing lip ( 3) and / or the lengths of the centering web (26) and the sealing groove (23) are the same or approximately the same as the lengths or proportions of the centering shoulder (4) and the sealing lip (3).
  • the outer diameter of the centering shoulder (4) is a few tenths of a millimeter (preferably 0.5 to 0.9 mm) smaller than the inner diameter of the centering web (26) and the centering shoulder (4) has at least one bucket latch (12) which can be non-positively locked in the closed state with at least one cover pawl (27) of the centering web (26).
  • the sealing lip (3) and the sealing groove (23) have an inclined position and / or the sealing lip is directed outwards, so that (in cross section) the sealing lip measures an acute angle with the vertical axis passing through the center of the bucket bottom vertical axis above the bucket opening to the sealing lip).
  • the sealing lip and the sealing groove always have a sealing system and function, even with different diameters and manufacturing tolerances of the buckets.
  • the outer web (25) is thicker or significantly thicker than the inner web (22) and / or the sealing groove (23) has a narrower gap or a slightly smaller opening width (preferably produced by dimensional shrinkage during manufacture) than the thickness or the cross section of the sealing lip (3), so that in the closed state the sealing groove (23) forms a press fit with the sealing lip (3).
  • one or more recessed grips (9) are arranged on the collar (5) of the bucket.
  • the recessed grips are preferably covered with securing elements (10), whereby according to a preferred embodiment the securing elements are connected to the collar via a perforation (11) or a material-thinned point, a depression or an incision or a notch, so that only when the Securing segments (10) via a perforation (11) and the like, grasping and loosening of the centering web (26) is possible.
  • the bucket collar has a concealed recessed grip at one or more points, and if a securing segment is deliberately destroyed and pressed in, the lid can be gripped and released using a perforation, notch and the like.
  • locking ribs (8) are formed below the recessed grip (9) in the protective space (6), which are locked or can be locked when the buckets are stacked into one another in the recessed grip (9). This prevents the individual buckets from twisting radially.
  • the locking ribs (8) (measured parallel to the central axis of the bucket) are longer than the ribs (7), but the average width of the locking ribs or the average diameter of the preferably radially arranged locking ribs is smaller than the width or the average diameter the radially arranged ribs (7).
  • the handles are always aligned in the same place.
  • the bucket and lid With a centering shoulder on the bucket and a centering web on the lid, the bucket and lid are fixed and centered on each other in filling systems and are therefore easy to use on all roll-on or press-sealers. Capping and closing by hand is also easy to do.
  • the special arrangement and location of the individual wall elements and the interaction of a sealing lip with a sealing groove result in a high-sealing closure.
  • the lid on the bucket again has so-called latches, which represent a high-strength, mechanically resilient closure.
  • the actual sealing and closing element of the lid is also protected by the centering bar on the lid and lies in the lower part of the lid.
  • the cover surface (21) preferably rests on the pressure flange (2) in the closed state and absorbs the weight of stacked buckets and transfers them to the bucket wall (1).
  • the centering web (26) of the cover has a downward-running, circumferential cover spring (28) in the form of a tip.
  • the collar (5) has at the transition to the centering shoulder (4) a collar groove (29) with a tip of the cover spring (28) adapted recess or with an angle of the tip of the cover spring (28) adapted recess, which in the closed state of the bucket and Adjust the centering heel (26) and collar (5) and thereby cause an axial and / or radial locking.
  • a pressure flange (2) is preferably arranged at a right angle or at an obtuse angle to the bucket wall (measured on the outer bucket wall boundary line or line which leads from the bucket bottom to the pressure flange) and the pressure flange (2) surrounds the bucket opening in an annular manner, whereby the centering bar (4) with the collar (5) is arranged directly and at right angles to the pressure flange (2).
  • the outer web (25) of the lid has a cylindrical outer surface and / or is arranged parallel to the centering web (26) or to the central axis of the bucket passing through the center of the bucket bottom.
  • this central axis is also the axis of rotation.
  • oval buckets or other shapes e.g. square buckets, e.g. represents the axis through which the planes of symmetry pass.
  • the angle between the inner web (22) and the outer web and / or the centering web is particularly advantageously 5 to 20 °, preferably 10 to 15 °.
  • the outer web has a wall thickness which is 1.5 to 4 times, preferably 2 to 2.5 times, thicker than that of the inner web and / or the cover surface.
  • ribs (7) are arranged between the bucket wall (1) and the centering shoulder (4) and the lip 3 is spaced apart from the ribs (7) when the buckets are stacked one inside the other in the cavity (6).
  • the lower edge of the collar (5) preferably lies on the upper edge of the collar (5) of the bucket arranged underneath.
  • the outer lid edge preferably the centering web of the lid, is arranged parallel or approximately parallel to the central axis running perpendicularly through the center of the bucket bottom and / or lid, the outer lid edge having at least two cylindrical or ring-shaped parallel or approximately parallel surfaces has differently large diameters, the outer web (25) with the smaller diameter passing over a step into the cylindrical parallel collar part, preferably centering web (26) with the larger outer diameter.
  • the sealing lip (3) is not arranged directly on the upper bucket wall, but on the pressure flange (2) delimiting the bucket, offset with respect to the inner wall of the bucket, the lower ends of the ribs (7) not being designed as stack stops and / or the length of the ribs (7) (except locking ribs (8) - measured in the vertical direction parallel to the central axis of the bucket and from the lower surface or side of the pressure flange) is smaller than half the length of the collar (5) (measured in the vertical direction parallel to the central axis of the bucket and from the lower surface or side of the pressure flange).
  • the height of the collar 5 results from the proportion of the taper of the Bucket to the wall thickness of the wall 1.

  • the collar 5 and the centering shoulder 4 are interrupted at one or more points offset inwards and form recessed grips 9. These recessed recesses 9 enable the cover 20 to be removed because an engagement surface is formed under the centering web 26. When the securing segment 10 is pressed in via the perforation 11, this contact surface is released. Below the recessed grip 9, locking ribs 8 are formed inside the collar 5.
  • the lid 20 When closing, the lid 20 is pressed directly vertically onto the bucket or placed loosely and pressed on by means of rollers and / or plates.
  • the sealing lip 3 serves the centering web 26 as a pre-centering. During the actual pressing on, the centering shoulder 4 of the bucket and the centering web 26 of the lid are locked. Through the Greater length 1 of the centering shoulder 4 to the length L 2 of the sealing lip, the sealing lip 3 is free when the closing begins, that is to say protected. Only when the centering shoulder 4 and the centering web 26 have been found centrally and have an exact guidance to one another, does the sealing lip 3 snap into the sealing groove 23. The lengths of the sealing groove 23 and the centering web 26 of the cover are congruent with the length L 1 and L 2.
  • the bucket and lid When closed, the bucket and lid form an outer cylindrical part X of the same diameter. There is thus a closed outer surface.
  • the lid cannot be unintentionally removed from the bucket. During transport and loading processes, the buckets and lids then always meet with this cylindrical outer surface X. It cannot damage the lock. Likewise, no possibility of attack under the lid edge is possible. The actual lock and the pawls 12 + 27 are protected inside the outer surface X.
  • the centering web (26) of the cover has a downward circumferential cover spring (28) in the form of a tip
  • the collar (5) has a collar groove (29) with a tip of the cover spring at the transition to the centering shoulder (4) (28) adapted recess.
