Container and stirring device

Abstract

A combined container and stirring device which can be used with and resembles the shape of known infusion bags is disclosed. The combined container and stirring device comprises a body made of material that is resistant to liquids. The body comprises a lower body and an upper body. A filter bag surrounding a granular, powdered, or liquid product is provided. The filter bag is arranged within a cavity in the lower body. The upper body wraps around the lower body to form a compact shape when the device is in a folded state. The upper body extends upwardly from the lower body to form a handle when the device is in an expanded state.

DETAILED DESCRIPTION

(14) Referring to FIG. 1, the body 1 of an exemplary combined container and stirring device is shown in a pre-assembled state. The body 1 is shaped as a flat elongated strip and may e.g. be made of waterproof cardboard, paper or plastic. The body 1 comprises an upper body 2 and a lower body 4 which are connected by a pre-creased body fold 3. Two pre-creased storage folds 5 or stamped edges for folding together of the upper body 2 are arranged longitudinally spaced proximal and parallel to each other. The distance between the pre-creased storage folds 5 is at least the height of the oval bottom section 43. The pre-creased storage folds 5 extend transversely to the longitudinal axis of the strip 1.

(15) Within the lower body 4 of the device an oval-shaped pre-creased bottom fold 6 is arranged. The pre-creased bottom fold 6 separates a first lower body section 41 from a second lower body section 42. Within the pre-creased bottom fold 6 a bottom section 43 is formed. The lower body 4 of the device is provided with two cutouts 7, which are formed opposing each other.

(16) As shown in FIG. 2, a flat filter member 13 may be attached to the lower body 4. The filter member 13 may e.g. be made of fabric mat or tea bag paper. The filter member 13 extends over the cutouts 7 in the lower body 4. When assembled, the filter member 13 within the lower body 4 forms a sealed filter bag 17. The filter member 13 may e.g. be glued or welded to the lower body 4. A granular, powdered or liquid product may be introduced in the lower body 4 with the opened-out filter fabric mat. A liquid product within the context of the present disclosure applies to viscous and pasty products.

(17) Subsequently, as shown in FIG. 3, the lower body 4 is folded at the oval-shaped pre-creased fold 6 so as to close the lower body 4 with the filter fabric mat 13 to form a kind of tea bag as a filter bag 17. The upper end 44 of the second lower body section 42 is now arranged next to the upper end 45 of the first lower body section and preferably firmly connected thereto, e.g. by gluing.

(18) In a further operation, as shown in FIG. 4, the upper body 2 is retracted at the pre-creased stamped edge or body fold 3. Finally, the two storage folds 5 of the upper body 2 are relocated so that the upper body 5 wraps around the lower body 4 and covers the filter bag 17 in a protective and framing manner. For connecting the upper body 2 to the lower body 4, the upper body 2 is provided with a flap 8 on its upper end, which can be inserted into a transverse slot 9 in the lower body 4 (see FIG. 5).

(19) FIG. 6 shows the device in its fully folded-together state in a perspective view. As can be seen, this general shape of device 1 corresponds approximately to the configuration of a conventional infusion bag, e.g., a conventional tea bag. In this way, space-saving and perpendicular storage is possible, preventing damage to the filter part. Flavoring and aromatic substances remain fresh and cannot escape.

(20) A drink is made by unfolding the upper body 2. The first and second lower body sections 41, 42 remain however folded onto each other. When the device 1 is expanded, lateral ribs 21, 22 are folded out by bending pre-creased handle folds 10, 11 which extend longitudinally along the lateral sides of the upper body 2. The lateral ribs 21, 22 may be bent at stamped edges or pre-creased handle folds 10, 11 until they extend approximately perpendicular to the center section 12 of the upper body 2. The center section 12 may be imprinted with content information, preparation times, or used for advertising imprints.

(21) As shown in FIG. 7, a stably formed and resistant construction is created by the folded out ribs 21, 22 from the center section 12 by means of the stamped handle edges 10, 11, through which the device 1 can be used as the stirrer, wherein the lower body 4 of the device 1 with the filter part 17 (the filter fabric mat/filter paper 13 or an inserted product 16) forms an agitator or a kind of spoon and the upper body 2 forms a type of handle.

(22) An alternative container and stirring device 1 is shown in FIG. 8 through 13. The illustrated alternative device 1 is designed such that known commercially available infusion bags 16, e.g. tea bag, can be held in it. In principle, the construction is the same as the embodiment described in FIGS. 1 to 7. Comparing the FIGS. 8 and 1 or FIG. 2, however, in this case, the filter fabric mat and tea bag paper 13 over the cutouts 7 are missing. In this case, the cutouts 7 in the form of a frame-like holder are used for this, so that the taste and flavoring substances may escape from the intermediate infusion bag 16. The separate infusion bag 16 can be seen from the FIGS. 9 to 13.

(23) In contrast to the embodiment according to FIGS. 1 to 8, however, the lower body 4 next to the slot 9 for the flap 8 has a further transverse slot 14 in the upper area of the lower body 4, in which a flap 15, which is located at the lower end of the lower body 4, can be inserted for closing of the lower body 4 (i.e., the creation of the filter part 17) and the simultaneous clamping the infusion bag 16.

(24) The device, which is formed from the elongated strip 1 and surrounds the bag-like filter part 17 (with the filter fabric mat/tea bag paper 13 or the infusion bag 16) in a frame-like manner, may consist of an environmentally friendly and degradable material. For example, water-resistant cardboard or biodegradable plastic is suitable for this purpose, which should only be as stable or resistant so that it remains correspondingly stable for at least several minutes in the liquid in order to be able to use the stirrer.

(25) The two embodiments have been described for the preparation of tea. The device is also suitable for other products which are prepared in the form of an infusion, e.g., soup, broth, dressing, ketchup, etc. Furthermore, the invention can also be used in camping, outdoor sports, etc. areas.

(26) While the present invention has been described with reference to exemplary embodiments, it will be readily apparent to those skilled in the art that the invention is not limited to the disclosed or illustrated embodiments but, on the contrary, is intended to cover numerous other modifications, substitutions, variations and broad equivalent arrangements that are included within the spirit and scope of the following claims.
