Description

The invention relates to a product receptacle for flow and / or pourable products with a filling and emptying opening, one in it releasably arranged spray insert or the like. And a closure cap, according the preamble of claim 1. Such a container is disclosed by DE 43 21 274.

Product receptacle with a filling and emptying opening, for example is neck-shaped, are widely known. In the drainage openings usually syringes are used to facilitate dosing or the like. With a compared to the outlet cross section of the product outlet smaller passage cross-section provided, for example there trapped. Most known containers for flowable and / or pourable Products are with firmly integrated dispensers and screw-on caps fitted. After emptying these containers, they are not or can only be used with difficulty because refilling is not or only is difficult to do. These containers are therefore usually only for one time Suitable for use from an economic and ecological point of view is unsatisfactory.

There are also known generic containers that a cup-shaped closure part with a metering opening in the bottom of the pot and one have hinged closure caps for closing the metering opening. These caps are detachable with their tubular area, in particular can be screwed into the product outlet of the container. For dosed Product removal, the cover can be opened and then close again. After emptying the container, the cap can be closed unscrew from the container, which then comes from a refill, for example from a flexible bag or a large container, Refilled the product into the container through the filling and emptying opening can be.

However, these closures have several disadvantages. For one, there is Danger that the user when unscrewing the closure in front of the Refill with the remaining product in contact with the cap comes, which is particularly unacceptable for dangerous substances. On the other hand, screwing in or screwing on the closure requires a great deal Care, otherwise there is no tightness between the closure and the Product leakage of the container is guaranteed, so that it is in a subsequent Dosage can lead to an undesirable leakage. About that in addition, the closure is not very user-friendly for the user unscrew it for refilling, put it somewhere and only afterwards after a long search to unscrew again.

There are also products such as highly effective household cleaners, Toilet cleaners and the like, which have a special safety lock, for example a child lock are locked. Such caps are usually formed in two parts and can only be opened by the outer part is first pressed down on the inner part and then is screwed on when pressed. With such secured and sealed product receptacles was previously an easy one Refillability not available. At most it was possible with the help of tools, such as pliers, scissors and the like. The jammed To remove the injection insert or the like, with the risk of come into contact with product residues or the contaminated spray insert in places or on objects that are adhered to by the adherent Product residues can be damaged.

The object of the invention is to provide a solution with which simple, inexpensive, reliable and material-saving way of using the syringe or the like for the refill of the product container and removed until can be kept safe for reinstallation.

With a product receptacle of the type mentioned in the beginning, this is Object achieved by the features of the characterizing part of claim 1.

This has the advantage that the syringe insert or the like does not match the product approach that comes in contact with the syringe insert pulled out of the filling and emptying opening and put back into it can be.

The cap is a tool for removing the syringe insert designed with a known internal thread. This has the Advantage that no separate tool is required to use the syringe to solve. At the same time, every manual contact is also with the edge area of the spray insert avoided. The first thread of the internal thread the closure cap engages radially behind the at least in some areas protruding edge area of the injection insert, so that this from the filling and drain opening can be pulled out. Particularly easy this succeeds when a tilting movement occurs simultaneously with the closure cap is executed so that the syringe insert from the filling and Emptying opening is levered out. The process of removing the Syringe insert is about loosening a crown cap by one Compare bottle opener.

The fact that the cap at the same time a recording for the syringe insert released from the filling and emptying opening has, it is avoided that the product residues Spray insert is deposited uncontrolled and unwanted contamination or even damage the respective pad.

In an embodiment, the closure cap has a concentric inside elongated tubular approach as a receptacle for the from the filling and emptying opening dissolved injection insert. This ensures that the Injection insert in the correct position and position during the refill process of the Product receptacle is kept in the cap and then by replacing or screwing on the cap again can be clamped in the filling and emptying opening.

The invention also provides a method for removing and storing the Injection insert from a filling and emptying opening of a product receptacle for liquid products with a filling and emptying opening, a syringe insert releasably arranged therein and a closure cap, wherein the injection insert or the like. By a tilting movement by means of the Tool inserted cap from the fill and drain opening is levered out and held in the cap, as explained in claim 3. For this, the Cap first loosened from the filling and emptying opening and then as a loose tool in engagement with the injection insert, in particular its at least partially radially projecting edge area, such brought that he levered out of the filling and emptying opening and then held in the cap by being in it oriented falls in. Then the syringe insert can be screwed on, Push on or the like. The cap with the held therein Syringe insert can be reinserted into the filling and emptying opening.

The cap becomes loose on the filling and Emptying opening with spray insert arranged therein or attached and the syringe insert is tilted by a internal thread profile of the cap behind the radial The protrusion of the spray insert reaches out of the filling and emptying opening levered out and in the concentric, tubular extension of the cap held. With such a screw cap Closure cap can by means of the first course of the already existing inside Thread behind the at least partially projecting radially Gripped the edge area of the injection insert and this by simple Leverage by means of a tilting movement with the least effort the filling and emptying opening and then in the cap to be caught. The injection insert comes right side in the concentric, elongated tubular extension of the cap to lie and can then by simply unscrewing the cap placed on the filling and emptying opening again in the filling and Emptying opening used, in particular be pinched.

on average a loose cap with the syringe insert held in it, released from the filling and emptying opening, in the overhead position.

A generally designated 1 and only partially shown product receptacle for flowable and / or pourable products has a container head 2 with a neck-shaped mouth part as a filling and emptying opening 3 and with a circumferential external thread 4. In the filling and emptying opening 3 is a spray insert 5 with a cross-section in relation to the outlet the filling and emptying opening 3 has a smaller average cross section 6 pinched. The product receptacle 1 is with a cap 7 closed with an internal thread 8, wherein in the figures a two-part cap 7 is shown with a child lock. The cap 7 has one in the closed position in the Mouth 6 of the injection insert 5 engaging sealing dome 9 and a concentric, elongated tubular extension 10. The injection insert 5 has a radial edge contour 11 of the filling and emptying opening 3 protruding edge area 12.

In the transport, storage or closed position shown in FIG. 1 the cap 7 is fixed with its internal thread 8 on the external thread 4 of the filling and emptying opening 3 of the product receptacle 1 screwed on. The sealing dome 9 engages sealingly in the outlet opening 6 of the insert 5 and prevents unwanted product leakage even when the product receptacle is lying flat or upside down 1.

The closure works as follows:

To dispense product, the cap 7 from the filling and emptying opening 3 by simply overhead positions or by pressurization unscrewed.

To refill the product receptacle 1, the closure cap 7, as shown in Fig. 2, loosely attached to the filling and emptying opening 3 and canted. The bottom thread of the internal thread engages 8 of the cap 7 on one side behind the radially projecting Edge area 12 of the injection insert 5. Lies on the other side the corresponding lowest thread of the internal thread 8 Cap 7 to a corresponding area of the external thread 4 of the filling and emptying opening 3 and is based on this. This creates a leverage effect when further lateral force is applied (Arrow A) on the closure cap 7 for levering out the injection insert 5 leads from the filling and emptying opening 3.

The injection insert 5 falls as soon as it comes out of the filling and emptying opening 3 has been released into the cap 7 and is stored in the overhead position therein, as shown in Fig. 3. The product receptacle 1 can now be refilled.

To reinsert the insert 5 into the filling and emptying opening 3 is the cap 7 with the syringe 5 stored therein reverse order back to the filling and emptying opening 3 initially attached and then screwed tight. This will make the injection insert 5 clamped again in the filling and emptying opening 3. In which next application process can then the cap 7 in the usual Unscrewed again from the filling and emptying opening 3 the insert 5 is now firmly seated again.

Of course, the invention is not based on the described embodiment limited. For example, it is also possible to use bets other than one Insert the insert 5 into the filling and emptying opening 3, for example for pourable and / or free-flowing products.
