The present invention pertains generally to the field of container, and more particularly to container for food.
Instant food such as cup ramen can be consumed instantly by adding hot water into its container. However, due to this capacity of hot water, the container should have a capacity larger than actual size of the contents such as dry ramen and condiment which are included in the package of the instant food. A large volume of the container causes difficulties in handling and a high cost for storage and transportation.
The present invention provides an adjustable container comprising a folded wall in the peripheral wall and reducing the size of the container by minimizing the empty space of the interior volume. Accordingly, this small-sized container can be convenient to handle and provide low cost for distribution. Also, because only small area of the container is revealed outside and printing material or packing material is saved, manufacturing cost can be reduced. Furthermore, various kinds of instant food in each container can be packed together in one pack.
Embodiments of the inventive concept provide a container comprising a floor; a peripheral wall extending upwardly from the floor, terminating at an upper opening, and defining interior volume, the peripheral wall having a first unfoldable part formed along at least two first fold lines, a sheet-type lid covering the upper opening, and wherein the adjustable container has at least two states: a first state that the first unfoldable part is folded and the adjustable container has a first interior volume, and a second state that the first unfoldable part is unfolded and the adjustable container has a second interior volume larger than the first interior volume.
Although the present invention is briefly summarized, the fuller understanding of the invention can be obtained by the following drawings, detailed description and appended claims.
These and other features, aspects and advantages of the present invention will become better understood with reference to the accompanying drawings, wherein:
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, which form a part of this disclosure. It is to be understood that this invention is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed invention.
Also, as used in the specification including the appended claims, the singular forms “a”, “an”, and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as form “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about”, it will be understood that the particular value forms another embodiment.
According to
The peripheral wall 103 extends upwardly from the floor 101 and terminates at an upper opening OPN. The peripheral wall 103 defines interior volume of the adjustable container 100. A structure of the floor 101 and the peripheral wall 103 may be a cup shape but is not limited to. In other embodiments of the present invention, a shape defined by the peripheral wall 101 may be various; for example, the shape may be square, triangle, rectangular, circle, oval, polygon, and the like.
The peripheral wall 103 comprises upper part 103U, an unfoldable part 103M, and lower part 103L. Each part can be divided by a first fold line 103FL1 and a second fold line 103FL2. The first and second fold lines 103FL1 and 103FL2 are formed along circumference of the peripheral wall 103. The upper part 103U is located above the first fold line 103FL1 and contacts the sheet-type-lid 105. The lower part 103L is located below the second fold line 103FL2 and contacts the floor 101. The unfoldable part 103M is located between two fold lines 103FL1 and 103FL2.
Referring to
Accordingly, the adjustable container 100 has at least two states providing different interior volume. In a first state shown in
The peripheral wall 103 may be made of materials commonly used in package for instant food such as paper with plastic liner. In other embodiments, the peripheral wall 103 can be made of flexible paper and further comprise stiffener or stiffener material. The stiffener can be employed inside or outside of the adjustable container 100 or embedded in the peripheral wall 103. The stiffener can be located along the fold lines 103FL1 and 103FL2 but not limited to. The stiffener material can be blended with the peripheral wall material during the peripheral wall fabrication. The stiffener or stiffener material can work as a spring force. Thus, once the adjustable container is released by removing the string 107, the unfoldable part 103M is unfold by itself or using a minimum force to unfold.
The sheet-type lid 105 covers the upper opening OPN. The sheet type lid 105 is attached to the top 103T of the peripheral wall 103. The sheet-type lid 105 is a flat shape extending in a plane. The sheet-type lid 105 may comprises a protruding area 105P beyond the outmost of the peripheral wall 103 and extending in the plane. The protruding area 105P can be used to affix the sheet-type lid 105 to the top 103T of the peripheral wall 103 to cover the upper opening OPN again after the sheet-type lid 105 is ripped to add water to the adjustable container 100. The protruding area 105P may be rolled and then engage with an outwardly rolled rim of the top 103T of the peripheral wall 103.
The adjustable container 100 may further comprise at least one string 107 connecting between the sheet-type lid 105 and the floor 101. In the first state shown in
According to
The adjustable container 100 containing instant food can be distributed in the first state. A consumer can partially detach the sheet-type lid 105 from the top side of the peripheral wall 103 and unfold the unfoldable part 103M, by removing the string 107 or manually pulling it, to make the adjustable container 100 have enough space for hot water BW. Then, she can add condiment DP and hot water BW into the adjustable container 100. Thereafter, consumer can make the sheet-type lid 105 cover the upper opening OPN while simmering.
