Definitions

  • the invention concerns a thin-walled container, comprising a wide-mouthed body and a snap-over lid, the body having near its mouth a radially extending external flange and locking means between the mouth and the flange and the lid having a top part and a rim, the rim being provided with locking means to engage with the locking means of the body.
  • These containers are generally known and are used to pack, for instance, 'do it yourself' products, such as adhesives and paints and other more or less dangerous products, including medicines.
  • a suitable process and material combination is injection moulding of a polyole­fin.
  • Manufacturers of such containers aim at reducing wall thickness, to decrease raw material consumption and to increase manufacturing speed; a thin-walled article cools down more quickly and can therefore be removed from the mould more quickly, resulting in an increased hourly production rate.
  • the container according to the invention is characterized in that the locking means of the body comprise an external clip which is situated below the point midway between the mouth of the body and the flange and in that no part of the top part of the lid projects beyond the plane through the edge of the mouth.
  • the container according to the invention can be manufactured at a high production speed without showing detrimental shrinkage of the mouth of the body.
  • a major advantage of the container according to the invention is that the same lid can be used for a foil-sealed and for a non-foil-sealed body, thus eliminating the need for an extra lid tool and the opera­tional and other facilities therefor.
  • a lid with an inner flat diaphragm extending from the rim is known as such from US-A-4,071,156.
  • An embodiment of the container according to the invention is characterized in that the configuration of the external clip matches a corresponding recess in the inner surface of the rim.
  • the advantage hereof is, that the overhang of the lid with respect to the wall of the body, i.e. the distance by which the outer edge of the rim of the lid projects beyond the outer surface of the wall of the body, has been minimized, so that the possibility that the lid of the container is accidentally lifted by another container (so-called 'riding up'), which can occur, for instance, under transit conditions of the containers or when containers are packed in a box, is also minimised.
  • the remaining wall thickness of the rim at the deepest point of the recess therein can best be chosen between 1/3 and 1/2 times the wall thickness of the wall of rim thereabove.
  • the thickness of the wall of the rim below the recess can best be chosen thinner than that above the recess, for instance, in combination with the range limits specified above, bet­ween 1/2 and 1/3 of the thickness of the wall of the rim above the recess.
  • Another embodiment of the container according to the inven­tion is characterized in that the side of the clip which faces the flange is substantially perpendicular to the body wall section between the flange and the mouth. This is to achieve extra good locking between the lid and the body.
  • the perpendicular height of the clip and the thickness of the wall of the body near the clip are not critical, but their ratio is preferably chosen between 1 and 2.
  • a further embodiment of the container according to the inven­tion is characterized in that the clearance between the free edge of the rim and the flange is less than 0.1 mm.
  • a preferred embodiment of the container according to the invention is characterized in that the flange is provided with a recess in radial direction, which at its deepest point coincides with the outer face of the rim.
  • the recess is to facilitate removing the lid of the container.
  • the overhang of the rim does not project beyond the deepest point of the recess, accidental removal or removal by children is still prevented.
  • the inner side of the rim wall is provided with a circumferential bead, which is situated between the diaphragm and the recess, the perpendicular height of the bead being between 0.1 and 0.2 times the rim thickness, and the inner radius of the rim plus the perpendicular height the of bead substantially equalling the outer radius of the upper part of the body wall.
  • This circumferential bead greatly facilitates the turning of the lid to align the thumb tab with the recess in the flange. Thereabove, the bead forms an extra seal against leakage of the con­tainer contents.
  • said preferred embodiment can be provided with near the outer edge of the flange, a skirt extending from the flange in a direction away from the mouth of the body, which flange and skirt preferably are stiffened by radial ribs which are substantially equidistant. This increases the rigidity of the wall and, in combination with a conical shape of the body below the flange, makes it possible to nest empty containers.
  • the container comprises a body 1 and a snap-over lid 2.
  • Body 1 comprises a mouth portion 3, a radially extending external flange 4 and locking means 5.
  • Lid 2 comprises a top part 6, a rim 7 and locking means 8, which engage with locking means 5 of body 1.
  • An essential characteristic of the invention is that no part of top part 6 projects beyond the plane through the edge 27 of mouth portion 3.
  • a lid with an inner flat diaphragm is shown.
  • Locking means 5 are preferably shaped as a sharp-edged clip 9 which radially extends from the upper part 10 of the body wall. Another essential characteristic of the invention is that contact sur­face 11 (see Fig. 3) of clip 5 is situated at a relatively large distance from edge 27 of mouth portion 3 and at a relatively small distance from flange 4. The exact location of clip 5 depends upon the thickness of the upper part 10 of the body wall, the stiffness of the material used for the container and the diameter of mouth portion 3.
  • Contact surface 11 preferably extends substantially perpen­dicularly to upper part 10 of the body.
  • Locking means 8 comprise a recess 12 in the inner face 13 of rim 7, contact surface 14 (see Fig. 3) preferably being substantially perpendicular to the outer wall of upper part 10.
  • Part 15 of rim 7, below recess 12 is preferably made thinner than part 16 of rim 7, above recess 12, to facilitate removing lid 2.
  • part of rim 7, near the deepest point 17 of recess 12 functions as an elastic hinge.
  • Flange 4 of the container is provided with a recess 19 in radial direction such, that the deepest point 20 thereof more or less coincides with the outer face of the rim (see also Fig. 3).
  • flange 4 is at its outer edge 23 provided with a down­wardly extending skirt 24 and ribs 25 (see also Fig. 2).
  • Rim 7 is provided with a thumb tab 18 (see also Fig. 2) which for easy removal of lid 2 can be aligned with recess 19 by turning lid 2.
  • the thumb tab preferably does not project beyond the outer edge 23 of flange 4.
  • the inner wall side 21 of rim 7 is provided with a circum­ferential bead 22, to facilitate the turning of lid 2.
