Definitions

  • the invention relates to a container which has a cylindrical pouring spout with an external thread and an attachment with an internal thread for screwing onto the pouring spout.
  • the attachment can be screwed to an end position in which the attachment rests against a stop of the pouring spout in the direction of rotation. In the end position, the attachment adopts a desired orientation, for example with respect to a front side of the container.
  • a container in the form of a detergent bottle is known from the prior art, in which an annular seal is provided for the seal between the attachment in the form of a screw cap and the pouring spout.
  • the seal is made of a material that is softer than a material of the attachment and than a material of the pouring spout.
  • the seal is arranged in the axial direction between an end edge of the pouring spout and an end contact surface of the attachment. When the attachment is screwed onto the pouring spout, the soft seal is compressed in the axial direction.
  • WO2017 / 167565 which falls under Art. 54 (3) EPC, discloses a container with an attachment having a seal.
  • the invention is therefore based on the object of providing a container with a pouring spout and an attachment which meets high requirements with regard to the sealing between the pouring spout and an attachment.
  • the seal has a first sealing element that, when the attachment is screwed on, is arranged in the radial direction between attachment and pouring spout is and rests on a lateral surface section of the pouring spout.
  • the first sealing element can thus also be referred to as a radial sealing element, since it is arranged in the radial direction between the components to be sealed.
  • the first sealing element can, for example, be designed as a circumferential sealing lip, with the sealing lip being able to have a thickness of less than 0.5 mm in the radial direction in the profile.
  • the thickness of the first sealing element in the radial direction can be 0.2 to 0.4 mm.
  • the attachment for the pouring spout can, for example, be designed as a closure cap in order to close the pouring spout.
  • the attachment is designed as a pouring aid.
  • the pouring aid can comprise a special pouring spout, which is intended to facilitate pouring out liquid from the container through the pouring spout.
  • the stop of the pouring spout can ensure that the pouring aid with the pouring spout is correctly aligned with the front side and / or with a handle of the container.
  • the pouring aid preferably has an external thread onto which an internal thread of a further attachment can be screwed.
  • This further attachment can, for example, be the closure cap described above.
  • the closure cap can thus be screwed onto the pouring spout both directly and indirectly via the pouring aid.
  • the pouring aid is screwed onto the pouring spout, on which in turn the closure cap is screwed.
  • the pour-out aid can have a stop beyond which the closure cap cannot be screwed onto the pour-out aid.
  • the attachment has an essentially cylindrical outer wall and an essentially cylindrical inner wall, which delimit a receiving space in the form of an annular cylinder for the pouring spout.
  • the cylindrical outer wall and / or the cylindrical inner wall can have shoulders, conical sections, threads, etc., as a result of which the outer wall or the inner wall deviate from a mathematically exact cylindrical jacket surface. Accordingly, the recording space is not a mathematically exact ring cylinder.
  • the seal can be arranged in the receiving space at a front end of the receiving space. This front end is preferably a closed end of the receiving space.
  • the receiving space is open on the opposite side so that the pouring spout can be moved into the receiving space when the attachment is screwed on. When the attachment is screwed on in the end position, only an upper end of the pouring spout can protrude into the receiving space.
  • the seal and the attachment are firmly connected to one another.
  • the fixed connection between the seal and the attachment is preferably created solely during the manufacture of the attachment and the seal, with both components being able to be produced by injection molding and one component can be molded onto the other.
  • the seal can first be injection molded onto or around which the attachment is injected.
  • the seal can comprise a first leg and a base, wherein the first sealing element is arranged on the first leg and can have a bulge facing the receiving space.
  • the first leg can rest with a rear side on a lateral surface section of the inner wall of the attachment and be firmly connected to it.
  • the first leg extends in the axial direction along the lateral surface section of the inner wall of the attachment.
  • the first sealing element closes the given gap between the lateral surface section of the inner wall of the attachment and the lateral surface section of the pouring spout.
  • the two lateral surface sections are radially opposite one another.
  • the bulge which is convex in section, lies against the lateral surface section of the pouring spout. Due to the bulge, there is an undercut in the axial direction. As will be described in more detail later, this undercut can be used to hold the seal in a fixed position within an injection mold for the attachment during the manufacture of the attachment.
  • the seal has a second sealing element on the base which, when the attachment is screwed on, is arranged in the axial direction between attachment and pouring spout and rests against an end edge of the pouring spout.
  • the seal thus provides a double seal: on the one hand by the first sealing element, which is arranged in the radial direction between two surfaces to be sealed, and on the other hand by the second sealing element, which is arranged between two surfaces to be sealed in the axial direction.
  • the thickness of the second sealing element in the axial direction is preferably greater than 0.5 mm. In one embodiment it is 0.7 to 1.7 mm. Thus, the thickness of the second sealing element in the axial direction is preferably greater than the thickness of the first sealing element in the radial direction.
  • a rear side of the base can rest against a radial web of the attachment.
  • the preferably circumferential radial web connects the inner wall and the outer wall of the attachment to one another in the above-mentioned exemplary embodiments, which have an annular cylindrical receiving space.
  • the front sides of the seal facing the receiving space are free of production-related surface structures.
  • Such surface structures can, for example, be injection points that can arise during injection molding.
  • the front sides of the seal can thus be particularly smooth, which is conducive to their sealing effect.
  • the preferably one-piece attachment can be made of plastic, preferably of polypropylene (PP).
  • a plastic is preferably also used for the material of the seal; thermoplastic elastomers (TPE) have proven to be particularly favorable here.
  • TPE thermoplastic elastomers
  • the material of the seal is softer than the material of the attachment and the material of the pouring spout, the material of the seal should not be too soft. Good seals are achieved with Shore A hardnesses of 30 to 90 or 60 to 80 ShA at 23 ° C for the material of the seal.
  • a groove open to the receiving space can be provided with groove side walls which diverge in the direction of a groove bottom.
  • the groove represents a (further) undercut which is used to hold the seal securely in position by means of a holding element during the manufacture of the attachment.
  • the seal is essentially U-shaped and has a second leg that is connected to the first leg by the base.
  • the second leg also extends in the axial direction.
  • a rear side of the second leg is firmly connected to a wall section of the attachment (for example the outer wall).
  • a projection directed towards the receiving space can be provided on the second leg, which projection generates a (further) undercut in the axial direction.
  • the undercuts described above ensure a firm connection between the seal and a holding device for the seal.
  • the holding device is used in the production of the seal and the production of the attachment, which is preferably carried out in a chronological manner.
  • the holding device serves as part of an injection mold for the seal. After the injection molding has taken place, the seal is placed in the injection mold of the attachment with the aid of the holding device.
  • the various undercuts and the U-shape of the seal ensure that the seal is firmly seated on the holding device, which simplifies the manufacture of the attachment and the seal.
  • the holding device can at least partially define the inner contour of the receiving space of the attachment.
  • the holding device can be constructed in several parts so that it can be pulled out of the receiving space after the attachment has been injection molded.
  • a special embodiment of the seal is disclosed here, which is used for the fixed connection between the seal and the holding element, for example, the seal in a further manufacturing step, in particular when the seal is overmolded with a other material to hold in place.
  • Figure 1 shows schematically a container 1 with a base body 2, which has a flattened front side 2a.
  • the base body 2 is almost completely filled with a liquid detergent 3, which can be seen from a fill level line 5.
  • a tapering region 6 adjoins an upper end of the base body 2, which is here conical and merges into a cylindrical pouring spout 7 with a central axis 4.
  • the base body 2 can also assume other shapes, for example a handle can be molded into the base body 2.
  • the region 6 which tapers between the base body 2 and the pouring spout 7 does not necessarily have to be conical either.
  • the container 1 further comprises an attachment 8, which has a cylindrical basic shape in the form of an upside-down pot or cup and sits on the pouring spout 7.
  • the attachment 8 has a cylindrical outer wall 9 and a cylindrical inner wall 10 which delimit a receiving space 11. Due to the cylindrical walls 9, 10, the receiving space 11 assumes the shape of an annular cylinder.
  • annular seal 12 is arranged, which, starting from the central axis 4, is arranged in the radial direction between the inner wall 10 and an upper end of the pouring spout 7.
  • the seal 12 thus seals an annular gap 13 between the inner wall 10 of the attachment 8 and the pouring spout 7.
  • a typical gap dimension for the gap 13 (radial distance between pouring spout 7 and inner wall 10 is 0.2 to 1.5 mm, preferably 0.2 to 1 mm, further preferably 0.2 to 0.5 mm, in the area of the seal.
  • the seal 12 is also 0.2 to 1.5 mm, preferably 0.2 to 1 mm, further preferably 0.2 to 0.5 mm thick, it being possible for it to be compressed or compressed in the seat shown 12 can have a thickness of 0.2 to 1.5 mm, preferably 0.2 to 1 mm, further preferably 0.2 to 0.5 mm, in the radial direction.
  • the receiving space 11 is delimited at an upper end by a circumferential radial web or connecting ring 14.
  • the radial web 14 connects the outer wall 9 and the inner wall 10.
  • the upper end of the receiving space 11 is closed by the radial web 14.
  • the attachment 8 is removed from the pouring spout 7.
  • no threads are shown with which the attachment 8 can be screwed onto the pouring spout 7.
  • the attachment 8 is designed as a closure cap 15.
  • the function of the attachment 8 in Figure 1 consists in sealing the pouring spout in such a way that no detergent 3 accidentally escapes from the container 1.
  • the seal 12 should be designed in such a way that no detergent 3 escapes from the container when the container 1 is lying or is upside down and the liquid detergent 3 is applied directly to the seal 12.
  • the volume of the base body is 0.5 to 5 I.
  • An inside diameter of the cylindrical pouring spout preferably has values between 30 and 50 mm. It should be emphasized at this point that Figure 1 shows the container according to the invention only schematically and the in Figure 1 aspect ratios shown are not limiting. For example, an axial length of the pouring spout can be smaller than the inner diameter (for example 10 to 30 mm).
  • the conical area 6 can also be so flat that the pouring spout 7 adjoins the base body 2 practically directly.
  • FIG. 11 shows, in section, an exemplary embodiment for the attachment 8, likewise in the form of a closure cap 15.
  • the closure cap 15 in the embodiment of FIG Figure 1 has the cap 15 of the Figure 2 the function of a measuring cup or a dosing cap, which is clear from two markings 16, 17 (50 ml and 70 ml).

  • Figure 5 shows the seal 12 on an enlarged scale, whereupon the circle marked V in FIG Figure 2 should indicate.
  • the circumferential seal 12 of the Figure 5 is essentially U-shaped in profile and has a first leg 21, a second leg 22 and a base 23 which connects the two legs 21, 22.
  • the first leg 21 lies with a rear side 24 on a lateral surface section 25 of the inner wall 10.
  • a diameter of the lateral surface section 25 is larger, preferably 1 to 4 mm larger, than the diameter of the remaining sections of the inner wall 10.
  • a first sealing element 26 is arranged on the first or radially inner leg 21 which has a convex bulge 27 which is formed in the direction of the inner side 19 of the outer wall 11.
