Definitions

  • the invention relates to a container according to the preamble of claim 1.
  • vent valve This can be made from an air-permeable, porous material.
  • the vent valve is usually integrated into the cap because that is the easiest place to install it.
  • vent valves made from porous materials can also serve to protect the container contents from microbes and bacteria. For design or functional reasons, locating the vent valve in the container closure is not always the optimal location. There is therefore a need to allow greater flexibility in the placement of the vent valve.
  • a closure cap is known in which a porous element is integrated to allow pressure equalization between the container interior and the environment.
  • the closure cap according to the WO 2010/081081 has a chamber on the underside of the lid with two openings: a lower opening through which the porous element is inserted into the chamber, and an upper opening that connects the chamber to the environment. To hold the porous element in the chamber, it can be dimensioned to ensure a snug fit. Alternatively, the lower edge of the chamber can be folded or provided with an undercut.
  • the EP-A-1 068 902 discloses a closure assembly comprising an elastic plug for closing a container opening and a filter medium integrated in the plug.
  • the plug has an axial opening which provides a connection between the container interior and the environment.
  • a filter disc is arranged in the opening of the plug, which lies sealingly against the cylindrical wall of the passage. It is proposed to form the filter disc in the opening integrally with the plug by injection molding.
  • the EP-A-1 068 902 no instructions on how this could be accomplished.
  • DE102007002865A1 discloses a container according to the preamble of claim 1.
  • the object of the present invention is to provide a holding device for functional elements on a container which can be fitted with a functional element under form-fitting conditions with little effort and yet sealingly and which can simultaneously be demolded with little effort during its production.
  • the invention relates to a plastic container with a container wall and an outlet opening.
  • the object is achieved with the container according to the preamble of claim 1 in that the insertion opening has a first clear width and the recess widens towards the interior of the container to a second clear width, wherein the second clear width is greater than the first clear width.
  • the recess has, at least in a partial area, a roof which is formed by a section of the container wall delimiting the insertion opening, and a functional element is held in the recess in a form-fitting manner.
  • the recess can be formed at any point on the container wall and is shaped such that the functional element is securely held in the recess after being inserted through the insertion opening.
  • the container wall is perforated to ensure contact between the inserted functional element and a product stored in the container interior, the functional element can be held sealed to the container wall in such a way that a product stored in the container interior cannot escape into the environment between the container wall and the functional element. Because the recess according to is oriented inwards, the container surface remains smooth and is not characterized by elevations The container design is extremely flexible, as it is not restricted by any positioning constraints. The extrusion blow molding process allows the container to be manufactured quickly and accurately.
  • the roof ensures that the functional element is held securely in the recess, which serves as the receiving chamber, with a form-fitting fit.
  • the roof can be straight, convex, or concave across a central axis of the recess.
  • the container wall in this section can also be designed as a tooth with a sharp or rounded tooth tip that roofs the recess.
  • the recess can also be covered in more than one partial area.
  • the roof can serve to fix the functional element in the axial direction.
  • the roof can be designed in such a way that the functional element is removable or permanently fixed. Removability can be ensured by the application of axial force or radial force, or by a combination of both.
  • the recess expediently has a wall and a base. This allows the functional element or insert to be pressed into the recess until it touches the base.
  • the wall can, for example, be pyramid-shaped or cylindrical and can form a polygon when viewed in the direction of a longitudinal extent of the recess.
  • the wall can also be oval, elliptical, or circular when viewed in the direction of a longitudinal extent of the recess.
  • the recess can also be formed with a shoulder which serves as a support surface or a stop surface for the functional element. In most cases, however, the wall will be circular-cylindrical.
  • the functional element is connected to the interior of the container.
  • the opening is generally positioned so that, when the functional element is inserted, the product cannot escape past the functional element.
  • the through-opening creates a permanent connection between the atmosphere surrounding the container and the interior of the container, in addition to the outlet opening.
  • the recess has a central axis which is essentially perpendicular to the container wall.
  • the recess it is also conceivable for the recess to have a central axis which encloses an angle with the container wall which is less than 90 and greater than 0 degrees, preferably less than 88 and greater than 10 degrees, and particularly preferably less than 80 and greater than 15 degrees.
  • This allows the orientation of the recess relative to the container surface to be flexibly selected. This is advantageous if a special container contour is required or the insertion opening should be as inconspicuous as possible.
  • the angle is less than 45° and greater than 30°.
  • the included angle comprises an angle in both the vertical and horizontal directions. The direction can be related to the base of the container.
  • the central axis can be perpendicular to the container wall in the horizontal direction, and in the vertical direction the included angle between the container wall and the central axis of the recess can be, for example, 75°.

  • the insertion opening has a first clear width, and the recess widens towards the interior of the container relative to the first clear width to a second clear width and then narrows to a third clear width.
  • This design of the recess is advantageous when the functional element is inserted into the recess with its smaller-diameter end first.
  • the recess is designed such that it encloses the outer surface of the functional element, and the undercut holds the larger-diameter end in a form-fitting manner.
  • the narrowing from the second clear width to the third clear width can occur abruptly, for example by means of a shoulder, a step, or a projection. This narrowing from the second clear width to the third clear width can also occur continuously or discontinuously over a predetermined distance.
  • the first clear width can be smaller, equal to, or larger than the third clear width.
  • the maximum roofing depression measured transversely to a central axis of the depression is between 0.05 mm and 1 mm and preferably between 0.25 and 0.5 mm. Due to these dimensional features, the cover has an overlap with respect to the recess, which, on the one hand, reliably holds the functional element in the recess and, on the other hand, allows the functional element to be pressed through the insertion opening.
  • the maximum overlap is the dimension between the edge of the cover, which also defines the insertion opening, and the wall of the recess.
  • the undercut can be demoulded and forms a sufficient force connection for connecting the functional element and the recess.
  • the recess has a substantially rotationally symmetrical shape.

  • a further aspect of the invention relates to a container as described above with a functional element accommodated in the recess.
  • the combination of recess and functional element allows them to be precisely matched, whereby the mating surface between the functional element and the recess wall is generally liquid-tight, but can also be designed to be gas-tight if special requirements are met.
  • an outer shape of the functional element and an inner shape of the recess correspond to one another in such a way that the functional element is held in the recess in a fluid-tight manner with respect to a product stored in the container interior.
  • the mating surface between the functional element and the wall of the recess can be designed to be fluid-tight.
  • the positive connection, caused by the roof, reliably holds the functional element in the recess, even if there is excess pressure in the container interior.
  • the roof can prevent the functional element from being displaced out of the recess in the direction of the central axis of the recess.
  • the functional element is expediently designed as a flanged bushing.
  • the functional element is The design of the collar adapts it to the contours of the recess, ensuring a particularly good fit and seal within the recess.
  • the functional element can also be in the form of a sleeve or a bushing without a collar.
  • a second through-opening is advantageously provided on the functional element to preferably enable gas exchange between the container interior and the environment. Depending on the function of the functional element, it can be in direct contact with the container interior to equalize pressure or fulfill other tasks described below.
  • the second through-opening can be smaller than 5 ⁇ m to retain liquid products from the container interior and can be smaller than 20 ⁇ m to retain pasty products from the container interior. With both opening sizes, unhindered gas exchange between the surrounding atmosphere and the container interior is possible.
  • the second through-opening is closed by a gas-permeable membrane. The membrane is only permeable to gases and is liquid-tight.
  • an internal pressure builds up inside the container due to a change in altitude or gas formation that is greater than the ambient pressure, this pressure can be equalized through the membrane. It is also conceivable that a negative pressure in the container can be equalized. A negative pressure can occur, for example, when a hot product is filled into the container and then cooled in the sealed container.
  • the membrane function can be simplified by using a sintered, porous part made of HDPE as the functional element.
  • the functional element is a single piece and therefore easy to manufacture. Gas can be exchanged between the container interior and the environment through the porous part, but liquid cannot pass through the functional part.
  • the functional element is a shelf life indicator.
  • the shelf life indicator is connected to the container interior and reacts to parameters that indicate a change in the filled product. For example, the formation of a gas or a change in pressure can be detected.
