Definitions
- Container with a depression in the container wall
- the invention relates to a container according to the preamble of claim 1.
- the containers are equipped with a ventilation valve.
- a ventilation valve This can be made of an air-permeable, porous material.
- the vent valve is integrated into the closure cap because it is the easiest to install. Ventilation valves made of porous materials can also serve to protect the contents of the container from microbes and bacteria.
- an arrangement of the ventilation valve in the closure of the container is not always the optimal location. There is therefore a need to allow greater flexibility in the arrangement of the ventilation valve.
- a cap in which a porous element is integrated, to allow a pressure equalization between the container interior and the environment.
- the cap according to WO 2010/081081 has on the underside of the lid a chamber which has two openings, a lower opening through which the porous element is inserted into the chamber, and an upper passage opening which connects the chamber with the environment. So that the porous element is held in the chamber, this can be dimensioned so that a snug fit is realized.
- the lower edge of the chamber may be folded or provided with an undercut.
- EP-A-1 068 902 discloses a closure assembly comprising an elastic stopper for closing a container opening and a filter medium integrated in the stopper.
- the plug has an axial opening that connects between the container interior and the environment allows.
- a filter disc is arranged, which bears sealingly against the cylindrical wall of the passage. It is proposed to form the filter disk in the opening integrally with the plug by injection molding.
- EP-A-1 068 902 does not give any instructions as to how this could be accomplished.
- the object of the present invention is to show a holding device for functional elements on a container, which may also be provided at locations other than the container closure.
- the invention relates to a plastic container with a container wall and a Austrittsöf fnu ng.
- the object is achieved in the container according to the preamble of claim 1, characterized in that the container is formed by extrusion blow molding and formed on the container wall into the container interior protruding recess for receiving a functional element, the recess accessible through an insertion
- the recess can be formed at any point of the container wall and is formed so that the functional element is securely held by the insertion opening in the recess after insertion. If the container wall is perforated in order to ensure contact of the inserted functional element with a product stored in the container interior, the functional element can be kept sealed with the container wall such that a product stored inside the container does not penetrate between the container wall and the functional element Environment can reach.
- the recess has, at least in a partial region, a roof which is formed by a section of the container wall bounding the insertion opening.
- the canopy ensures that the functional element is held securely in the recess, which serves as a receiving chamber.
- the roof can be formed transversely to a central axis of the recess straight, convex or concave.
- the container wall can also be formed in this section as a tooth covering the depression with a sharp or rounded tooth tip.
- the depression can also be covered in more than one subregion.
- the roofing can serve to fix the functional element in the axial direction.
- the roof can be designed such that the functional element is removably or permanently fixed. The removability can be ensured by axial force or radial force or by a combination of both forces.
- the recess has a wall and a bottom.
- the functional element or the insert can be pressed into the depression until it abuts the base.
- the wall can be pyramid-shaped or cylindrical, for example, and can in each case form a polygon in the direction of a longitudinal extension direction of the depression.
- the wall can also be oval, elliptical or circular when viewed in the direction of a longitudinal extension direction of the recess.
- the depression can also be formed with a shoulder, which is designed as a bearing surface or as a stop surface for the functional element. In most cases, however, the wall will be circular cylindrical.
- the functional element is connected to the container interior.
- the opening will be arranged such that, when the functional element is inserted, there will be no escape of the product past the functional element.
- a permanent connection between the atmosphere surrounding the container and the container interior is formed in addition to the outlet opening.
- the depression has a central axis which is essentially perpendicular to the container wall. According to a further embodiment, however, it is also conceivable that the depression has a central axis which encloses an angle with the container wall which is smaller than 90 and greater than 0 degrees, preferably smaller than 88 and larger than 10 degrees, and especially preferably less than 80 and greater than 15 degrees. As a result, the orientation of the depression relative to the container surface is flexibly selectable. This is advantageous if a special container contour is required or the insertion should be as inconspicuous. In one embodiment, the angle is less than 45 ° and greater than 30 °. The included angle encompasses both an angle in vertical and horizontal direction.
- the direction can be related to the footprint of the container.
- the center axis in the horizontal direction can be perpendicular to the container wall and, in the vertical direction, the included angle between the container wall and the central axis of the depression can be 75 °, for example.
- the insertion opening has a first clear width and the depression widens in the direction of the container interior to a second clear width, wherein the second clear width is greater than the first clear width.
- the depression can surround the functional element and hold it in a form-fitting manner.
- the insertion opening has a first clear width and the depression widens in the direction of the container interior opposite the first clear width to a second clear width and then narrows to a third clear width.
- This embodiment of the recess is advantageous when the functional element is inserted with its smaller diameter end ahead in the depression.
- the recess is designed in this case such that it encloses the lateral surface of the functional element and the undercut holds the diametrically larger 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 heel, a step or a projection. This narrowing from the second width to the third clear width can also take place over a predetermined distance continuously or discontinuously.
- the first clear width may be smaller, equal or greater than the third clear width.
- the maximum roofing depression measured transversely to a center axis of the depression between 0.05 mm and 1 mm and preferred between 0.25 and 0.5 mm.
- the roofing has an overlap with respect to the depression, which on the one hand reliably holds the functional element in the depression and on the other hand the functional element can be pressed through the insertion opening.
- the maximum roofing is the dimension between the edge of the canopy, which at the same time limits the insertion opening, and the wall of the depression.
- the undercut is demoldable and forms a sufficient adhesion for the connection of Functional element and recess.
- the recess has a substantially rotationally symmetrical shape.
- the depression is easier to demould than if it had a polygonal shape.
- fits between the functional element and recess are easier to make if they have a rotationally symmetrical shape.
- Another aspect of the invention relates to a container described above with a functional element received in the recess.
- the combination of recess and functional element, these can be adapted to each other exactly, whereby the mating surface between the functional element and recess wall is usually liquid-tight, but wasdpn can also be designed gas-tight in special requirements.
- an outer shape of the functional element and an inner shape of the depression correspond to one another in such a way that the functional element is held in the depression in a manner that is non-fluidly sealed in relation to a product stored in the container interior.
- the mating surface between the functional element and the wall of the recess can be made liquid-tight.
- the positive connection, caused by the roof, keeps the functional element reliably in the recess, even if an overpressure prevails in the interior of the container.
- the roofing can prevent the functional element from being displaceable out of the depression in the direction of the center axis of the depression.
- the functional element is designed as a flange bushing.
- the functional element is in its outer contour adapted by the design of the collar to the contours of the depression and is therefore particularly well-holding and sealingly received in the depression.
- the functional element can also be in the form of a sleeve or a socket without a collar.
- a second passage opening is provided on the functional element in order to preferably allow a gas exchange between the interior of the container and the environment. Depending on the function of the functional element, it can be in direct contact with the interior of the container in order to equalize pressure or to fulfill other tasks described below.
- the second passage opening may be smaller than 5 ⁇ to retain liquid products from the container interior and may be less than 20 ⁇ to retain pasty products from the container interior. Both opening sizes allow unhindered gas exchange between the surrounding atmosphere and the interior of the tank.
- the second passage opening is closed by a gas-permeable membrane. The membrane is only permeable to gases and is liquid-tight.
- an internal pressure which is greater than the ambient pressure, builds up in the interior of the container as a result of a change in the sea level or due to the formation of gas, this can be compensated for through the membrane. It is also conceivable that a negative pressure in the container can be compensated. A negative pressure can, for example, arise when a hot product is filled into the container and is cooled in the sealed container.
- the membrane function can be implemented in a simplified manner by virtue of the functional element advantageously being a sintered, porous part made of HDPE.
- the functional element is in one piece and accordingly easy to manufacture.
- the porous part allows gas to be exchanged between the interior of the container and the environment, but not liquid to pass through the functional part.
- the functional element is a durability indicator.
- the shelf life indicator communicates with the container interior and responds to parameters indicative of a change in the bottled product. For example, the formation of a gas or a pressure change can be detected.
- the functional element contains a chemical substance that can be in fluid communication with the interior of the container.
- the chemical substance may also be an odor trap, oxygen scavenger, water scavenger or a CO 2 scavenger.
- a chemical substance can be applied in the functional element, which captures gases which arise during the storage of the container.
- the functional element is an indicator which indicates when the cold chain of the product stored in the container has been interrupted.
- FIG. 1 shows a cross section through the container wall of a plastic container with a recess in a first embodiment
- FIG. 2 shows a cross section through the container wall of a plastic container with a depression in a second embodiment
- FIG. 3 shows a cross section through the container wall of a plastic container with a recess in a third embodiment
- FIG. 4 shows a cross section through the container wall of a plastic container with a recess in a fourth embodiment
- Figure 5 a side view of a plastic container with recess.
- FIG. 1 a detailed section of a container made of plastic material is shown.
- the container is numbered overall by the reference numeral 11.
- a recess 15 is formed at any point.
- the recess 15 serves as an Aumahmehunt for a functional element 17.
- the functional element 17 is inserted through an insertion opening 19 into the recess 17.
- the recess 15 is exemplified in the container terwandung 13 of the container 11, which is formed in the present embodiment as a side wall, provided in the vicinity of the container bottom.
- the recess 15 is preferably arranged at a position at which the functional element 17 can be in contact with the product stored in the container 11, even if the container is partially emptied. In principle, any position on the container wall 13 is possible.
- the recess or the receiving chamber 15, in addition to the insertion opening 19 has a wall 21 and a bottom 23. If the functional element 17 is received in the depression 15, then it is preferred that it touches the base 23.
- the functional element 17 can be held in the depression 15 in a force-fitting and / or form-fitting manner.
- the outer dimensions of the functional element 17 and the inner dimensions of the recess 15 are matched to one another such that a press fit is present.
- a holder under adhesion is shown in FIG.
- the recess 15 For holding the functional element 17 in the recess 15 under positive engagement, the recess 15 has a roof 25. To form the canopy 25, the recess 15 in the region of the insertion opening 19 has a first clear width 27, which widens in the direction of the container interior to a second clear width 29.
- the external dimensions of the functional element 17 are essentially adapted to the roofing dimensions. For this purpose, the functional element 17 widens from a collar 31 to a larger diameter collar 33.
- the difference between the first and second clearances 27, 29 is between 0.6 and 1 mm and preferably between 0.7 and 0.9 mm. This difference enables a reliable holding of the functional element 17 in the depression 15 and makes it possible for the collar 33 to still pass through the smaller-diameter insertion opening 19 while widening the same.
- the transition between the first and second clearances 27, 29 is formed by a roof flank 35.
- the flank 35 forms with the wall 21 or the center axis 37 of the depression an angle between 20 and 50 degrees, and preferably between 30 and 40 degrees. If the center axis 37 is at right angles to the parting plane of the container 11, then the canopy is easier to demould than with a different orientation of the center axis 37. This is because the half-shells of the container form open in the direction of the central axis 37. However, it is also conceivable that the central axis has an angle between 0 and 90 degrees, preferably between 10 and 88 degrees, and particularly preferably between 15 and 80 degrees, and that the recess 15 is nevertheless demoldable.
- Movable elements in the tool are also conceivable in order to accomplish demolding.
- Recesses 15 having such an orientation are preferred if required by the container design. For example, an orientation of the center axis 37 at right angles to the container surface for a uniform container design is advantageous.
- the depression 15 narrows, starting from the second clear width 29, to a third clear width 39.
- This embodiment of the recess 15 is selected when the functional element 17 is received in the recess 15 with the collar 31 in front.
- the functional element 17 and the depression 15 preferably have a rotationally symmetrical shape.
- a first passage opening 41 may be provided at the bottom of the recess 15. It is understood that, for this reason, a second through-opening 43 can also be provided on the functional element 17. As FIGS. 3 and 4 show, the second through-opening 43 can be offset according to the outer contour of the functional element 17.
- the functional element 17 can fulfill a wide variety of tasks. By way of example and therefore not conclusively, the following applications are conceivable:
- the functional element 17 may be a housing with the second through-opening 43 provided therein.
- a membrane 45 is inserted in the second passage opening 43. Since the membrane is expediently only permeable to gases, the same pressure prevails in the interior of the container as in the environment. Thus, there is a gas exchange between the container interior and the container 11 surrounding atmosphere. Deformation of the container 11 due to sub- Overpressure in the container interior can therefore be prevented.
- the membrane 45 may be made of conventional membrane materials, for example polyethylene (PE) or polytetrafluoroethylene (FTFE), polyamide (PA) or polyacrylonitrile.
- a simplified membrane function of the functional element 17 can be achieved in that the functional element 17 is a sintered, porous plug, for example made of HDPE.
- This porous material has the properties of a gas-permeable membrane.
- the functional element 17 can also be a durability indicator. It is in connection with the container interior. If a gas forms in the interior of the container, which indicates the end of the shelf life of the filled product, the functional element can change color. For example, a chemical substance may be present in the functional element which changes the color in reaction with the resulting gas.
- a chemical substance can be given up, which indicates an interruption of the cold chain and thus indicates a spoiled food in the container.
- the container 11 is produced with the recess 15 described above in the manufacturing process of extrusion blow molding.
- One possibility of production is the process described in EP 2227369.
- a displaceable mandrel can be provided in one of the mold half shells.
- the mandrel is moved out of the mold half-shell into the cavity at the same speed as the separation of the mold half-shells, so that the mandrel does not move relative to the container when the half-shells are opened.
- the mandrel is withdrawn from the formed recess 15 with the container being retained by a retainer. If the depression 15 is formed as shown in FIG. 4, the mandrel can be pulled out of the depression 15 when the half-shells are opened, without the need for a counterholder for retaining the container.
