Abstract

A deformable small packaging structure for free-flowing products, comprising a valve-like closure (10) produced by a two-component injection molding process and including a dimensionally stable carrier element (11) and an outer jacket (12) which envelopes the carrier element (11) at least in part and has a flexible squirt-nozzle (16) with slotted openings, should be constructed in such a manner that the squirt-nozzle (16) in withdrawn state occupies an extremely small space and that the change to the position clearing the openings is possible with little force application.

According to the invention, the outer jacket (12), in relation to the withdrawn squirt-nozzle (16), has a meander-shaped configuration adjacent to the squirt-nozzle (16). The squirt-nozzle (16), in relation to the withdrawn state, is configured as a pot-shaped recess. According to a preferred embodiment, the outer jacket (12) has an inner annular flange (17) which engages in a recess of the carrier element (11) and is firmly connected therewith. Further, the outer jacket (12) has adjacent to the inner annular flange (17) a circumferential web (18) which engages in a groove of the carrier element (11) and is also firmly connected therewith.

The deformable small packaging structure according to the invention is used in particular for condiments, like e.g. mayonnaise, ketchup, mustard and the like.

Claims

1. Deformable small packaging structure for free-flowing products, comprising a valve-like closure (10) produced by a two-component injection molding process and including a dimensionally stable carrier element (11) and an outer jacket (12) which envelopes the carrier element (11) at least in part and has a flexible squirt-nozzle (16) with slotted openings, characterized in that the outer jacket (12), in relation to the retracted squirt-nozzle (16), has a meander-shaped configuration adjacent to the squirt-nozzle (16).

2. Deformable small packaging structure according to claim 1, characterized in that the squirt-nozzle (16), in relation to the withdrawn state, is configured as a pot-shaped recess.

3. Deformable small packaging structure according to claim 1, characterized in that the outer jacket (12) has an inner annular flange (17) which engages in a recess of the carrier element (11) and is connected therewith.

4. Deformable small packaging structure according to claim 3, characterized in that the outer jacket (12) has a circumferential web (18) disposed adjacent to the inner annular flange (17) and engages in a groove of the carrier element (11) and is firmly connected therewith.

5. Deformable small packaging structure according to one or more of the preceding claims, characterized in that the carrier element (11) has outer thread turns (19) for receiving a screw cap.

6. Deformable small packaging structure according to one or more of the preceding claims, characterized in that the carrier element (11) has a step-shaped cross section, wherein the area receiving the outer jacket (12) has a smaller diameter than the area facing the body of the small packaging structure.

7. Deformable small packaging structure according to one or more of the preceding claims, characterized in that the carrier element (11) has a sleeve-shaped configuration and includes adjacent to the outer jacket (12) an annular groove (13) which is bounded by two groove walls (14, 15), and that the carrier element (11) is recessed inwardly above the annular groove.

8. Deformable small packaging structure according to one or more of the preceding claims, characterized in that several radial stabilizing ribs (20) are arranged between the squirt-nozzle (16) and the annular flange (18) and disposed at an angular distance relative to one another.

9. Deformable small packaging structure according to claim 8, characterized in that the stabilizing ribs (20) are formed onto the squirt-nozzle (16) and end at a distance to the annular flange (17).

10. Deformable small packaging structure according to one or more of the preceding claims, characterized in that the outer jacket (12) is recessed inwards adjacent to the upper groove wall (14).

11. Deformable small packaging structure according to one or more of the preceding claims, characterized in that the outer jacket (12) ends adjacent to the upper groove wall (14).

12. Deformable small packaging structure according to one or more of the preceding claims, characterized in that at least the squirt-nozzle (16) is made of oil-resistant plastic.

13. Deformable small packaging structure according to one or more of the preceding claims, characterized in that at least the shoulder of the small packaging structure adjacent to the squirt-nozzle (16) is made of oil-resistant material, preferably of a thermoplastic vulcanized material (TPV).
