Foldable spoon

Abstract

A foldable spoon being a flat blank in the initial state, and having two adjacent sections with fold lines carved so as to form a shank and a cup-shaped part in a folded state, wherein between the adjacent sections with fold lines there is a perforated boundary which contacts the fold lines of adjacent sections, the fold lines have elongated holes in the form of slits for fasten purpose arranged in such a way that one section has one hole and the other has two such holes; what is more, the fold line on one of the sections forms a retainer.

Claims

1. A foldable spoon comprising: a flat blank, comprising two adjacent sections each having with fold lines carved so as to form a shank and a cup-shaped part in a folded state, wherein between the adjacent sections with fold lines there is a perforated boundary which contacts the fold lines of each of the adjacent sections, and at least one of the fold lines on each section has an elongated hole in the form of a slit for fastening purposes arranged in such a way that one section has one hole and the other section has two such holes, wherein each of the holes are aligned in the folded state, and one of the fold lines on one of the sections folds to form a retainer which is inserted through each of the holes in the folded state thereby retaining the shank and cup-shaped part in the folded state.

2. The foldable spoon as set forth in claim 1, wherein there are three fold lines formed on each of the adjacent sections.

3. The foldable spoon as set forth in claim 1, wherein the fold lines are formed by the same die as the original flat blank.

4. The foldable spoon as set forth in claim 1, wherein the flat blank is made of food grade plastic.

5. The foldable spoon as set forth in claim 1, wherein the flat blank is made of food cardboard.

6. The foldable spoon as set forth in claim 1, wherein the flat blank is made of laminated cardboard.

7. The foldable spoon as set forth in claim 1, wherein the flat blank is made of polystyrene.

8. The foldable spoon as set forth in claim 1, wherein the flat blank is made of polypropylene.

Description

(1) Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

(2) FIGS. 1, 2, 3, 4, 5, 6, 7, 8 and 9 show the foldable spoon, wherein the numbers indicate: 1. Flat blank, 2. First adjacent section, 3. Second adjacent section, 4. Fold lines, 5. Perforated boundary, 6. Elongated holes in the form of slits, 7. Retainer, 8. Shank, and 9. Cup-shaped part. The foldable spoon shown in the figures is structured as follows.

DETAILED DESCRIPTION OF THE INVENTION

(3) Flat blank 1 consists of the first 2 and second 3 adjacent sections. Flat blank 1 has fold lines 4 and perforated boundary 5 separating first 2 and second 3 adjacent sections. Flat blank 1 consists of elongated holes in the form of slits 6 and retainer 7. The foldable spoon shown in the figures works as follows. Originally the claimed spoon is a flat product with preformed fold lines and perforation. The process of the claimed spoon manufacturing begins with the break/fracture of flat blank 1 along perforated boundary 5 resulting in the separation into first 2 and second 3 adjacent sections. After that the blank is folded along fold lines 4 in order to shape an accordion, thus, automatically forming cup-shaped part 9 of the blank opposite the holes 6.

(4) After that the accordion-folded section 3 is superimposed on the accordion-folded adjacent section 2 so that they match together. At the same time, elongated holes in the form of slits 6 automatically match together, too, so that it became possible to thread retainer 7 through them, thus obtaining securely fastened shank 8.

(5) The above particular properties ensure an easy manufacturability of the flat blank for the claimed spoon which, for example, can be manufactured using a form die. Moreover, the claimed construction provides the high shape holding capability when using it due to the reliable and firm sections folding along fold lines which maintains a geometrically simple and reliable construction and effective fixation through the slits by the retainer which allows to achieve the claimed technical result, namely, manufacturability of the preform as well as the shape holding capability when using the claimed utility model.

(6) The claimed design of the foldable spoon can be successfully applied for manufacturing (including last-volume production) disposable cutlery. It can be used in diverse fields, namely, in pharmacy for taking liquid and bulk drugs and dietary supplements, in household chemistry, animal feeding as well as in the field of construction and renovation materials, etc.

(7) While the invention has been described with reference to an exemplary embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
