Abstract

A stick-shaped paper container according to the present invention is introduced herein, and comprises a covering body, a base seat and a sleeving unit, the respective entire structure of all which is integrally compression-molded with only rendering positive draft angles, respectively, only by a wet-fiber pulp-molding process applied for wet plant-fibrous pulps, thereby being capable of simplifying its mold assembly and lowering its mold cost. The covering body, the sleeving unit and the base seat are assembled together into the entire stick-shaped paper container having a container height-to-width ratio between 2˜5.5.

First claim

What is claimed is:

1. A stick-shaped paper container, configured for accommodating a content therein, comprising:
a sleeving unit, configured for restricting the content from transversal movement, having a first and second end both opposed against each other, an annularly standing sleeve wall located between the first and second ends and formed around a longitudinal centre line, and a hollowed sleeve chamber formed, along the longitudinal centre line, between the first and second ends, wherein the first end is formed with a first opening space-communicated with the hollowed sleeve chamber and provided for the content passing therethrough, the hollowed sleeve chamber is formed with an innermost sleeve sidewall in a position of propping the content, and the standing sleeve wall is formed with an outermost sleeve sidewall;
a covering body, having a closed top distal end, a fitting-on distal end opposed against the top distal end, a standing cover wall located between the top distal end and the fitting-on distal end and formed around the longitudinal centre line, and a hollowed cover chamber formed, along the longitudinal centre line, between the top distal end and the fitting-on distal end, wherein the fitting-on distal end is formed with a fitting-on opening space-communicated with the hollowed cover chamber, the hollowed cover chamber is formed with an innermost cover sidewall therein, the covering body is disposed with the first end of the sleeving unit, and the standing cover wall has an outermost cover sidewall; and
a base seat, configured for longitudinally supporting the content, having a closed bottom terminal, an abutting terminal opposed against the bottom terminal, a hollowed base chamber formed, along the longitudinal centre line, between the bottom terminal and the abutting terminal, and a standing base wall located between the bottom terminal and the abutting terminal and formed around the longitudinal centre line, wherein the abutting terminal is formed with a receiving opening space-communicated with the hollowed base chamber, and is disposed at a position corresponding to the second end of the sleeving unit, in such a way of accommodating the content within between both the covering body and the base seat, and the standing base wall has an outermost base sidewall; and wherein
the covering body and the base seat both are integrally formed, respectively, only by a wet-fiber pulp-molding process where a male mold is used to dredge up wet plant-fibrous pulps, and then the male mold and a female mold both compression-mold the wet plant-fibrous pulps, in such a way that the entire structure of each of the covering body and the base seat is formed with positive draft angles relative to the longitudinal centre line, wherein the covering body, the sleeving unit and the base seat are assembled together into the entire stick-shaped paper container which has a maximum container height parallel to the longitudinal centre line, a maximum container width perpendicular to the longitudinal centre line, and a container height-to-width ratio, between 2˜5.5, of the maximum container height being relative to the maximum container width.

2. The stick-shaped paper container according to claim 1 , wherein the sleeving unit is integrally formed by the wet-fiber pulp-molding process where the male mold dredges up the wet plant-fibrous pulps and then the male mold and the female mold both compression-mold the wet plant-fibrous pulps, in such a way that the entire structure of the sleeving unit is formed with positive draft angles relative to the longitudinal centre line.

3. The stick-shaped paper container according to claim 2 , wherein the outermost sleeve sidewall is divided, by along the longitudinal centre line, into an annularly outer narrow-diameter section, an annularly outer wide-diameter section, and an outer circular saddle formed on a boundary between the outer narrow-diameter section and the outer wide-diameter section, wherein the first end passes through the fitting-on opening to enter inside the hollowed cover chamber while the fitting-on distal end is disposed with the first end, and the innermost cover sidewall and the outer narrow-diameter section both are respectively formed with flatted surfaces longitudinally extended in such a way of constituting a plane-to-plane tight contact in a mutually resting-on manner between the innermost cover sidewall and the outer narrow-diameter section, and an inner diameter of the fitting-on opening is smaller than an outer diameter of the outer circular saddle, thereby blocking the fitting-on distal end on the outer circular saddle from moving.

4. The stick-shaped paper container according to claim 2 , wherein the second end of the sleeving unit is formed with a second opening space-communicated with the hollowed sleeve chamber, and the innermost sleeve sidewall is divided, by along the longitudinal centre line, into an annularly-narrowed inner diameter section, an annularly-widened inner diameter section, and an inner circular saddle formed on a boundary between both the annularly-narrowed inner diameter section and the annularly-widened inner diameter, wherein the abutting terminal passes through the second opening of the sleeving unit to enter inside the hollowed sleeve chamber while the abutting terminal is disposed with the second end, the annularly-widened inner diameter section and the outermost base sidewall both have flatted surfaces extended toward the same direction in such a way of constituting a plane-to-plane tight contact in a mutually resting-on manner between the annularly-widened inner diameter section and the outermost base sidewall, and an outer diameter of the abutting terminal is smaller than an inner diameter of the inner circular saddle and is smaller than the inner diameter of the fitting-on opening of the covering body, thereby blocking the abutting terminal on the inner circular saddle from moving.

5. The stick-shaped paper container according to claim 4 , wherein an outer diameter of the abutting terminal of the base seat is smaller than an inner diameter of each of both the second opening of the sleeving unit and the fitting-on opening of the covering body.

6. The stick-shaped paper container according to claim 2 , wherein after the covering body and the sleeving unit both are assembled together, the covering body and the sleeving unit both are respectively positioned with the corresponding positive draft angles relative to the longitudinal centre line.

7. The stick-shaped paper container according to claim 1 , wherein the sleeving unit is constituted by assembling at least two sleeves in a nested or stacked manner along the longitudinal centre line.

8. The stick-shaped paper container according to claim 7 , wherein while the at least two sleeves are assembled in the nested manner, the content is restricted from both transversal and longitudinal movements within between the at least two sleeves, by an interlocking retention between a couple of interlocking components respectively formed on the at least two sleeves.

9. The stick-shaped paper container according to claim 1 , wherein the covering body and the base seat both are substantially the same in their entire structure and dimension, wherein while the covering body, the sleeving unit and the base seat are assembled together into the entire stick-shaped paper container, and the covering body and the base seat both are disposed in a reverse-position manner with relative to each other.

10. The stick-shaped paper container according to claim 1 , wherein after the covering body, the sleeving unit and the base seat are assembled together into the entire stick-shaped paper container, the second end of the sleeving unit rest
