Carrier used for preparing beverage and method for fabrication of the same

A method for fabrication of a carrier used for preparing beverage, comprising the following steps of:

• step S1, massively fabricating a number of paper-made containers, and further comprising:
• step S1A, by way of compression forming of a mold assembly of wet-fiber paper-molding process, integrally forming a solid geometric shape of a respective paper-made substrate which comprises a cup top portion having a first opening, a cup bottom portion, and an annular cup wall standing in extension between said cup bottom portion and said cup top portion, and by way of demolding of said respective paper-made substrate along a demolding direction corresponding to said mold assembly, making said annular cup wall being laterally formed with at least one protrusive portion and said demolding direction paralleling with a central axis of said annular cup wall, wherein said at least one protrusive portion is formed alongside a lower half portion of an inner circumferential surface of the annular cup wall, and is extended transversely and inwardly, toward the longitudinally central axis, from the lower half portion of the inner circumferential surface of the annular cup wall, to terminally form an innermost surface;
• and
• step S1B, forming an isolating layer over an entire inner surface of said respective paper-made substrate, thereby fabricating the respective corresponding paper-made container;
• step S2, one-by-one nesting said number of paper-made containers, in an alignment, into a stack assembly, wherein by way of stopping and position limiting of said at least one protrusive portion between each two nested ones of said paper-made containers, a longitudinally position-limiting interval is retained between the each two nested paper-made containers;
• step S3, with said longitudinally position-limiting interval, sequentially one-by-one drawing out said respective paper-made container from said number of aligned paper-made containers of said stack assembly while said respective paper-made container passes through component-picking of a component-assembling production line, thereby sequentially one-by-one equipping said respective paper-made container with a corresponding filter which partitions inside said paper-made container into a first carrying space and a second carrying space;
• step S4, filling medium of said beverage within said first carrying space of said respective paper-made container, to make an upper surface of said filter carrying said beverage medium;
• and,
• step S5, making a bottom plane of a sealing lid firmly adhering onto an annular surface of a cup top portion of said corresponding paper-made container, to watertightly seal said first opening and said first carrying space of said respective paper-made container, and to preserve said corresponding filter and said carried beverage medium inside said paper-made container, for constituting said respective corresponding carrier.

A carrier used for preparing beverage, comprising:

• a paper-made container, comprising a cup top portion having a first opening, a cup bottom portion, an annular cup wall standing in extension between the cup bottom portion and the cup top portion, and an isolating layer formed over an entire inner surface of the paper-made container;
• a filter, assembled inside the paper-made container to partition the paper-made container into a first carrying space that is defined between an upper surface of the filter and the cup top portion, for storage of medium corresponding to the beverage, and a second carrying space that is defined between a bottom surface of the filter and the cup bottom portion, for storage of a fluid of the beverage generated by action of the beverage medium;
• and
• sealing lid, having a bottom plane acting on firm adhesion onto an annular surface of the cup top portion, to watertightly seal the first opening and the first carrying space of the paper-made container in a way of preserving said filter inside the paper-made container;
• wherein a solid geometric shape of the paper-made container is integrally formed by way of compression forming of a mold assembly of wet-fiber paper-molding process, and by way of demolding of the paper-made container along a demolding direction corresponding to said mold assembly, the annular cup wall is laterally formed with at least one protrusive portion and said demolding direction parallels to a longitudinally central axis of said annular cup wall, wherein the at least one protrusive portion comprises a number of separated lateral protrusions distributed along an upper half portion, abutting underneath the cup top portion, of an outer circumferential surface of the annular cup wall, and the respective lateral protrusion is outwardly extended to protrude transversely away from the upper half portion of the outer circumferential surface of the annular cup wall, and terminally forms an outermost surface with a completely evenly-flatted plane, longitudinally extended in a specific longitudinal length from the cup top portion to terminate at a stopping end portion, by a structural relationship that the entire outer circumferential surface of the annular cup wall and the entire outermost surface of the respective lateral protrusion both are respectively formed with positive draft angles relative to said demolding direction, in a way to ensure that the respective paper-made container is sequentially one-by-one assembled to constitute the respective corresponding carrier while the respective paper-made container passes through a component-assembling production line where the paper-made container is provided in plurality, each two of which are respectively located upper and lower in an one-by-one nested alignment, to be in a manner that the stopping end portion of the respective lateral protrusion of an upper one of the each two nested paper-made containers stops over the annular surface of the cup top portion of the other lower one of the each two nested paper-made containers, to position-limit a nested depth, between the each two nested paper-made containers, in the specific longitudinal length of the outermost surface of the respective lateral protrusion, thereby retaining a longitudinal position-limiting interval between the each two nested paper-made containers, and to make the longitudinally central axes of the each two nested paper-made containers retaining a substantial collinearity.
