Definitions

• the invention relates to a packaging container for receiving a flowable product, which is formed by an outlet bung which can be closed in a rigid envelope and which is associated with an opening associated therewith, the outlet bung having an abutment integrally formed on the bungneck at the edge of the opening can be fixed and is provided with a laterally directed product outlet pipe which branches radially laterally from an axially directed upper part of the outlet bung, the outlet cross-section of which by means of a cylindrical tube extending into the upper part with a corresponding opening of a ver which can be rotated relative to the outlet bung ⁇ closing cap can be closed and released, a radially outwardly extending fixing flange being formed between the upper part and the bung neck.
• the closable container outlet is preferably made in three parts.
• the closable container outlet consists of a flexible sack, e.g. B. by welding fixed abutments, a bung into this abutment and a bung Sealing cap.
• the outlet bung is provided with a laterally directed product outlet pipe which branches radially laterally from an axially directed cylindrical inner pipe of the outlet bung, the outlet cross section of which is formed by means of a cylindrical pipe extending into the inner pipe with a corresponding opening which is rotatable relative to the outlet bung Sealing cap can be closed and released.
• the cross-section of the cylindrical inner tube of the outlet bung is considerably smaller than the cross-section of the abutment, which can lead to complications during emptying if higher-viscosity media are used.
• this problem does not occur during filling, since the outlet bung is then separated from the abutment and is only injected into the abutment after filling.
• this closure is made in two parts, ie the abutment and the outlet bung consist of only one part onto which the closure cap can be pushed, then only the small cross-section of the cylindrical inner tube of the outlet bung is available for filling and emptying, which in particular slows down the filling process , which leads to higher filling times and thus costs.
• This closure could then be enlarged overall in order to obtain a larger cross section, but this would lead to a higher material expenditure and thus higher manufacturing costs.
• the packaging container for receiving this larger closure can be designed accordingly larger.
• the object of the invention is to provide a solution which makes it possible to construct the closure of a container of the type in question in two parts such that the passage cross section of the closure is as large as possible while maintaining a reliable seal and using as little material as possible is, the closure should be space-saving at the same time.
• this object is achieved according to the invention in that the tubular upper part with a lateral product outlet tube is formed on the outer edge of the fixing flange and the bung neck beyond the fixing flange by means of an inner tube piece into the lower end of the upper part below Product outlet tube is extended such that an annular gap is formed between the upper part and the inner tube piece for sealingly receiving the inner tube of the closure cap.
• the invention provides that a circumferential snap bead is formed in the area of the annular gap at the upper part of the outlet spout and at least one circumferential snap groove is formed at the lower end of the cylindrical tube of the closure cap.
• This connection between the sealing cap and the outlet bung ensures a secure locking of both elements, which forms a good guidance of the sealing cap in the outlet bung when opening or closing when twisted.
• the connection between the two elements is established by beating the closure cap after the container has been filled. It is particularly expedient if two circumferential snap grooves are formed at the lower end of the cylindrical tube of the closure cap.
• the closure cap can first be applied to the outlet bung in a so-called pre-bounce position before the container is filled, in that the closure cap is only bounced so far that the bump of the outlet bung in the lower snap groove of the ver ⁇ the end cap snaps into place.
• the closure cap is then removed again and, after filling, is completely pushed into the outlet bung, ie by snapping the snap bead into the second snap groove.
• a particularly good seal between the outlet bung and the closure cap is achieved if the inner tube piece of the outlet bung widens conically in the region of the annular gap towards the fixing flange and the lower end of the cylindrical tube of the closure cap is correspondingly beveled on the inside. After the closure cap has been completely pushed in, these conical sealing surfaces lie against one another in a sealing manner.
• a further advantageous embodiment of the invention provides that the closure cap with a cylindrical outer wall surrounds the upper end of the upper part of the outlet bung to form a second annular gap.
• This design of the cap is a second Guide between the cap and outlet bung created, whereby the twisting of the cap to open or close is facilitated.
• a circumferential snap bead is formed on the cylindrical tube of the closure cap in the region of the second annular gap and at least one inner circumferential snap groove is formed on the upper end of the upper part of the outlet bung, two being also on the upper end of the upper part of the outlet bung internal circumferential snap grooves can be formed.
• This additional locking at the upper end of the outlet bung further improves the guidance between the two elements, with the provision of two snap grooves also providing an additional locking in the pre-impact position.
• outlet cross section of the product outlet tube and the opening of the cylindrical tube of the closure cap are oval, the outlet cross section or the opening being formed with an edge bead on the side facing each other.
• This embodiment with an enlarged outlet cross-section is provided in particular when more viscous media are to be used.
