说明书全文 | The present invention relates to a container being able to stand by itself as said container is erected from its flatly collapsed state to its three-dimensional state. The present invention particularly relates to such container enabling a quantity of content therein to be measured. The container is well known which is able to stand by itself as it is erected from its flatly collapsed state to its three-dimensional state even before filled with the content. Such collapsible container is disclosed, for example, in Japanese Utility Model Publication Gazettes Nos. A typical example of such containers of well known art will be described in reference with The paper sheet-like blank is formed by an outside member (1) and an inner member (2) both being substantially rectangular and laminated with each other. The outside member (1) comprises shape-retainable paperboard and provided with a plurality of cutting edge-marked fold lines (a) - (f) and a punched opening (6). The inside member (2) is formed by flexible film, e.g., polyethylene film. The paper sheet-like blank comprises a bottom forming section (3) destined to form a bottom of the container and side wall forming sections (4) contiguous to both sides of said bottom forming section (3) via the cutting edge-marked fold lines (b), (c). The bottom forming section (3) includes a bottom plate (5) corresponding to the container bottom, substantially triangular punched openings (6) and is formed along transversely side edges with cutouts (7). The side wall forming sections (4) respectively comprise side walls (8) corresponding to the container side walls, side margins to paste up (9) contiguous to both side edges to the respective side walls (8) via the cutting edge-marked fold lines (d) and top margins to paste up (10) contiguous to said side walls (8) via the cutting edge-marked fold lines (f). Erection of the container starts to fold the bottom forming section (3) outward along the cutting edge-marked fold line (a) bisecting the bottom forming section (3). Then side wall forming sections (4) are folded inward along the respective cutting edge-marked fold lines (b), (c). In this way, the blank presents a substantially W-shaped cross-section as seen in In this step, the container is still in its collapsed state, i.e., in a relatively flat envelope-like state. Now the bottom forming section (3) is unfolded along the cutting edge-marked fold line (a) and thereby the container is three-dimensionally erected so that the container can stand by itself. Through a top opening, fluid content such as drink powder, instant coffee or curry roux is poured into the container and heat-sealed along the top margins to paste up (10) to obtain a relatively flat product, as shown in To unseal the product, the top margins to paste up (10) are cut off along the cutting edge-marked fold lines (f) and thereby the container top is opened as shown in It should be understood that this container could be manufactured and supplied without any content, i.e., as the container alone. The container is stored in its flatly collapsed state and, in actual use, three-dimensionally erected as the container being able to stand by itself. Of the collapsible container as has been described above, the container provided at an upper predetermined position on the side wall (8) with a projection (k) serving as a measuring line is disclosed in Japanese Utility Model Application Disclosure Gazette No. The container disclosed therein allows a user to determine whether the container has been filled with the content to a level indicated by said projection (k) or not. However, it is impossible for this container of prior art to measure an exact quantity of the content has been poured into the container. It is principal object of the present invention to provide a collapsible container of simplified construction facilitating the content of the container to be easily measured. European patent application According to the present invention, there is provided a collapsible measuring container comprising shape-retainable and airtight opaque paper sheet-like blank folded substantially in W-shape and having transversely opposite side edges bonded together so that the container may stand by itself, said collapsible measuring container being characterized in that:
In this way, a quantity of the content can be easily measured without deterioration of the container's shape-retainability. A lower end of said window is position to be slightly spaced above from a bottom of the container. Such arrangement contributes to the shape-retainability of the container. After the content has been consumed until the surface if the content comes behind the lower edge of said window, it is no more possible to measure its quantity. To compensate such inconvenience, there is provided auxiliary measuring means to measure a small quantity of the content remaining in the container. The drawings will be described more specifically: Identification of reference numerals used in the drawings is as follows: 1 outside member, 2 inside member, 3 bottom forming region, 4 side wall forming region, 5 base plate, 6 punched openings , 7 cutouts, 8 side wall, 9 side margins to paste up, 10 top margins to paste up, 11 window, 12 graduations, 13 supplementary graduations,14 shape-retainer, 15 opening, 16 cutouts, 17 cutouts, 18 small window , 19 supplementary graduations, a - f depressed folding lines. Details of the present invention will be more fully understood from the description given hereunder in reference with The collapsible measuring container according to the invention is characterized in that the side wall (8) of said self-supporting collapsible measuring container of prior art is additionally provided with a window (11) and graduations (12). The window (11) is substantially transparent so that the content can be visually recognized from the exterior. The graduations (12) are marked on the window (11) itself or in the vicinity thereof so that the content seen through the window (11) can be measured. The outside member (1) may be made of shape-retainable paperboard or synthetic resin sheet, for example, thick paper having a basis weight of 157 g/m2. The side wall (8) of the container is formed in at least its one face with a slot-like punched opening as the window (11). The window (11) vertically extends substantially in the middle of said side wall face when the container is assembled and self-stands. The window (11) extending to the bottom of the container would result in deterioration of the container's shape-retainability. In view of such anxiety, a lower end of the window (11) is appropriately spaced above from the container's bottom and thereby a desired strength of the container is maintained. Along transversely opposite side edges of the window (11), graduations (12) for measurement, for example, in a range from 50 ml to 500 ml, are printed at intervals of 10 ml on the container. If a quantity of the content is less than 50 ml, the surface of the content would be lower than the lower end of the window and it would be impossible to measure the quantity by visual recognition from the exterior. The present invention solves this problem by providing the container with supplementary measuring means. As will be apparent from A small quantity of the content may be measured also using an alternative supplementary means illustrated by The paper sheet-like blank comprises the outside member (1) and the inside member (2) made of substantially transparent seen-through film. The outside member (1) contributes to a shape-retainability of the container and the inside member (2) contributes to an airtightness of the container. The inside member (2) preferably comprises two-layered laminated film-like sheet consisting of stretched polypropylene of 25 µ and polyethylene of 40 µ from the viewpoint of airtightness and manufacturing cost. The supplementary graduations (13) provided on the inner surface of the container may be printed on the inside member (2). However, the graduations (13) are preferably printed on the outside member (1) since these graduations (13) must be precisely positioned with respect to the window (11) of the outside member (1). The container filled with a large quantity of the content may be laterally expanded under a weight of the content and make exact measurement difficult. To overcome this problem, there is provided a shape-retainer (14). As illustrated by One or more such shape-retainer(s) may be put on the container from above and/or below to hold the container around the outer peripheral surface of its side wall (8). The container is thereby forcibly shape-retained to prevent undesirable lateral expansion of the container and to ensure a precise measurement. When it is desired to supply the container separately of the content, the shape-retainer (14) may be dimensioned sufficiently small to be appropriately packaged together with the container. The container according to the present invention is adapted to be flatly and compactly collapsed for storage and to self-support immediately before filled with content for its actual use. In spite of its simplified construction, this collapsible container itself facilitates a quantity of the content to be measured. This collapsible measuring container is further provided with the supplementary means used to measure a small quantity of the content remaining in the container with a high precision. As will be apparent from the foregoing description, the present is not limited to the container for food and drink and applicable also to a measuring instrument useful for various purposes. For example, the container according to this invention can be useful as a disposable container for the urine test. |
