Description

Long column shaped paper container
Technical Field
The utility model relates to a paper container in the technical field of packing material, in particular to a long column-shaped paper container manufactured by a wet fiber Pulp molding (Pulp-molded) process.
Background
In order to rapidly manufacture the existing packaging container, most of the components of the existing packaging container are made of plastic materials integrally, or a part of paper components and a part of plastic components are formed, so that the environmental protection requirement of Biodegradable (Biodegradable) or Compostable (Compostable) cannot be met; secondly, if the body of the consumer (e.g., lips or skin) frequently touches the plastic container (e.g., lipstick or plastic wrap for cosmetics), it is liable to cause health concerns for the human body over a long period of time.
As shown in fig. 1, although there is an integrated production machine 1 of the existing pulp molding process production line, which applies the existing pulp molding (or wet fiber paper molding) process to press wet plant fiber slurry by matching the upper male mold 22 and the lower female mold 24 in pairs to form various large-sized 3C paper packaging materials, the existing pulp molding process has the following technical problems (1) because the existing pulp molding process uses the slurry fishing concave chamber 242 of the lower female mold 24 to fish up the wet plant fiber slurry 28 (or slurry fishing) from the slurry tank 26 and then performs pressure molding together with the upper male mold 22, the ratio R1 of the longitudinal molding depth H1 of the slurry fishing concave chamber 242 of the lower female mold 24 to the transverse molding width W1 of each side of the slurry fishing concave chamber 242 is mostly limited to be less than or equal to 1 (i.e. H1/W1-R1, r1 ≦ 1); after the upper male mold 22 and the lower female mold 24 are clamped and pressed, the overall shape of the finally formed existing pulp molded product 16 mostly presents a flat box body (for being used as a 3C packing material) with a transverse width w1 'equal to a longitudinal height H1' or a transverse width w1 'greater than the longitudinal height H1', that is, a ratio r1 of the longitudinal height H1 '(parallel to the longitudinal forming depth H1) of the existing pulp molded product 16 to the transverse width w 1' is less than or equal to 1 (i.e. H1 '/w 1' ═ r1, r1 ≦ 1). If the transverse forming width W1 of the slurry fishing concave chamber 242 of the lower female die 24 is too small but the longitudinal forming depth H1 is too deep (i.e. the ratio R1 is greater than 1), a bridging phenomenon (bridging Effect) is likely to occur during the forming process of the longitudinal long cylindrical pulp molded product, that is, the longitudinal wall surface of the formed longitudinal long cylindrical pulp molded product is likely to be damaged or the wall surface thickness is too thin, so that the structural strength is insufficient, and further the problem of poor production yield is caused.
Secondly, when the longitudinal long cylindrical pulp molded product is manufactured by the existing pulp molding process, if the longitudinal wall surfaces of the longitudinal long cylindrical pulp molded product need to be laterally molded together with tenon structures and/or groove structures, the demolding surfaces of the lateral tenon structures and/or the lateral groove structures will present negative draft angles relative to the longitudinal center line T1 (or referred to as vertical draft direction) common to the upper and lower male and female molds 22 and 24 of the two longitudinal drafts, but the demolding surfaces of other remaining parts (such as the longitudinal wall surfaces and the corresponding transverse bottom surfaces) of the longitudinal long cylindrical pulp molded product present positive draft angles; when the product is molded, the upper male die and the lower male die of the two longitudinal drawing dies are matched with the transverse die of the other horizontal drawing die and/or the horizontally moving slide block device to actuate, so that the whole longitudinal long cylindrical pulp molded product including the lateral tenon structure and/or the lateral groove structure can be molded together. It can be understood that if the longitudinal long cylindrical pulp molding product has different parts of the positive draft angle and the negative draft angle, the number of the mold parts used in the existing pulp molding process is much larger and more complicated, the cost of the mold equipment for production is increased, the maintenance is not easy, the production yield is poor, and the production cycle of the product is prolonged. See PCT international publication No. WO2020019098a1, which discloses: the exterior of the upper cover 10 is provided with a plurality of straight grooves 11, the exterior of the lower cover 20 is provided with a plurality of straight large grooves 21, the large grooves 21 form a step surface 23 on the inner wall of a lower inner cavity 22, wherein the lateral molding of the grooves 11, the large grooves 21 and the step surface 23 (like a lateral tenon structure) has a negative draft angle, and another horizontal mold for horizontal draft and/or a horizontally moving slide block device are/is used for matching and molding with two male and female molds for longitudinal draft.
Therefore, there is a need for a long cylindrical paper container manufactured by an improved pulp molding process to solve the above-mentioned various technical problems occurring in the existing pulp molded container.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and the claimed invention is not limited to the embodiments, and should be defined by the claims.
Please refer to fig. 2, which is a schematic cross-sectional view of an integrated automatic production machine of the pulp molding process line 70 according to the present invention, wherein the integrated automatic production machine of the pulp molding process line 70 is used for manufacturing a product mainly including at least one moving device (not shown), a slurry fishing and pre-pressing device 80, a vacuum pumping device (not shown), a pressure forming device 90 and a cutting device 98.
The apparatus 80 comprises a first female mold 82 located above and a first male mold 84 located below and opposite to the first female mold 82. In the present invention, the term "female mold" is defined as a mold having a concave structure recessed inward from a molding surface, and is mostly used for molding the outer peripheral surface of the long columnar paper container member, and the term "male mold" is defined as a mold having a convex structure protruding inward and outward from the molding surface, and is mostly used for molding the inner peripheral surface of the long columnar paper container member. The first male mold 84 is provided with a plurality of first pillars 85 spaced apart from each other, each of the first pillars 85 is arranged in a multidimensional array and vertically protrudes from the upper surface of the first male mold 84, the outer circumferential surface of each of the plurality of first pillars 85 may be a cylindrical surface, a rounded conical surface, a truncated conical surface, or a bell-shaped curved surface without limiting the outer shape thereof, and the plurality of first pillars 85 can be used for mass production of the components of the long cylindrical paper container 10 (see fig. 3A). In the preferred embodiment, each of the first studs 85 has a first stud maximum height H2, and the stud aspect ratio R2 of the first stud maximum height H2 to the first stud maximum width W2 is greater than 1 (i.e., H2/W2-R2, R2 > 1); however, in other preferred embodiments, the first pillar 85 having a pillar aspect ratio R2 smaller than 1 can be replaced according to actual production requirements. Correspondingly, a plurality of first vertical holes 822 separated by the same space are formed inside the lower surface of the first female die 82, the configuration positions and the size ratios of the plurality of first vertical holes 822 are respectively matched with (aligned with) the configuration positions and the size ratios of the plurality of first upright posts 85, and the longitudinal inner peripheral surface of each first vertical hole 822 is also a cylindrical surface, a round-head conical surface, a truncated conical surface or a bell-shaped curved surface. In addition, the entire outer peripheral surface of each first upright post 85 of the first male mold 84 and the entire inner peripheral surface of each first upright hole 822 of the first female mold 82 are uniformly distributed with a plurality of micro holes (not shown) which are respectively communicated with the vacuum-pumping equipment through the exhaust channel to exhaust moisture and/or air (for vacuum-pumping).
As depicted in fig. 2, when the automated manufacturing station of the pulp molding process line 70 is in production, the first male mold 84 is initially lowered by the Slurry scooping and pre-pressing device 80 into a Slurry tank 86 for storing pulp (Slurry) containing a large amount of wet plant fiber Slurry 81; then, the first male mold 84 is vacuumized by the vacuum-pumping equipment, so that the whole longitudinal outer peripheral surface of each of the plurality of first upright columns 85 of the first male mold 84 uniformly adsorbs a layer of the wet plant fiber slurry; then, the slurry bailing and pre-pressing device 80 moves the first female mold 82 and the first male mold 84 up and down respectively to close the molds and apply a shallow pressure to pre-press the wet plant fiber slurry between the first female mold 82 and the first male mold 84, wherein each of the first vertical holes 822 of the first female mold 82 and the corresponding first upright posts 85 of the first male mold 84 are closed together by a corresponding longitudinal closing center line Y1, so as to integrally press-mold each component of the long cylindrical paper container 10 (see fig. 3A); meanwhile, a vacuum environment is formed between the two first male and female molds 84 and 82 by the above-mentioned vacuum pumping manner, and a part of moisture and/or water contained in the wet plant fiber slurry 842 is discharged, so that a wet paper product 42 (or wet blank) composed of the wet plant fiber slurry is formed between the first female mold 82 and the first male mold 84. In a practical case, the pulp 81 composition is composed of bamboo pulp and sugar cane pulp; however, the present invention is not limited to the composition and ratio, the working pressure range, the working temperature range and the moisture content range of the pulp 81, because the composition and ratio, the working pressure range, the working temperature range and the moisture content range of the pulp 81 used by the pulp dragging and pre-pressing device 80 can be changed according to different product structures and requirements.
Next, as shown in fig. 2, the wet paper product 42 is vacuum-absorbed below the first female mold 82 by the vacuum-pumping device, and the at least one moving device moves the first female mold 82 together with the absorbed wet paper product 42 to a position between a second female mold 92 and a second male mold 94 of the press molding device 90. After the vacuum suction is released, the first female mold 82 releases the wet paper product 42 to place the wet paper product on the second male mold 94 of the press molding apparatus 90. Since the arrangement positions and the size ratios of the second female mold 92 and the second male mold 94 of the pressure molding apparatus 90 are respectively the same as those of the first female mold 82 and the first male mold 84 of the slurry and pre-pressing apparatus 80. For example, the second male mold 94 also has a plurality of second vertical posts 942 on the upper surface thereof, the ratio of the positions and the sizes of the second vertical posts 942 is the same as the ratio of the positions and the sizes of the first vertical posts 85 of the first male mold 84, and the second female mold 92 has a plurality of spaced second vertical holes 922 formed inward on the lower surface thereof, the ratio of the positions and the sizes of the second vertical holes 922 is the same as the ratio of the positions and the sizes of the first vertical holes 822 of the first female mold 82.
Then, as shown in fig. 2, the press molding apparatus 90 closes the second female mold 92 and the second male mold 94 up and down respectively and applies a higher pressure to heat and press the wet paper product 42 between the second female mold 92 and the second male mold 94, and simultaneously evacuates most of the moisture and/or water contained in the wet paper product, thereby forming a dried paper product 44 made of dried plant fiber. Next, as shown in fig. 2, the cutting device 98 is used to cut off the excess parts of the dried paper product 44, so as to form the components of the long cylindrical paper container 10 (the cover 12 shown in fig. 3A, which will be described in detail later) which are completely made of dried plant fiber. In the present embodiment, the cutting device 98 is a conventional circular cutting machine for cutting a pattern or other conventional cutting devices.
Referring further to fig. 2 and 3A-3C, fig. 3A is a perspective view of a long cylindrical paper container 10 according to a first preferred embodiment of the present invention. The cardboard container 10 is used for hermetically accommodating the contents 100 inside the cardboard container 10, and the main components of the cardboard container 10 include: a cover 12, a sleeve 14 and a base 16. In the preferred embodiment, the cover 12, the sleeve 14 and the base 16 are all integrally manufactured by the integrated automatic manufacturing machine of the pulp molding process line 70 shown in fig. 2. The "content" 100 as referred to herein is a solid structure, including but not limited to, cosmetics, lipstick strips, 3C electronics, ornaments, slim appliances for specified purposes, and the like.
Referring to fig. 3A-3C, in the preferred embodiment, the sleeve member 14 is a single sleeve for tightly covering the outer peripheral surface of the content 100 to limit the lateral movement of the content 100, and has two opposite first and second ends 142 and 144, an annular sleeve standing wall 146 formed between the first and second ends 142 and 144 and surrounding a longitudinal centerline G1 (parallel to the longitudinal mold clamping centerline Y1 shown in fig. 2), and a sleeve hollow cavity 148 formed between the first and second ends 142 and 144 and penetrating the longitudinal centerline G1. The first end 142 forms a first opening 1422 communicating with the hollow cavity 148 of the sleeve and used for the contents 100 to pass through. The second end 144 forms a second opening 1442 communicating with the hollow cavity 148 of the sleeve and for the contents 100 to pass through. The sleeve hollow cavity 148 is used for accommodating the content 100 and forms a sleeve innermost wall surface 1482 facing the content 100. The sleeve upstanding wall 146 has a sleeve outermost wall surface 1462, the sleeve outermost wall surface 1462 being the longitudinal inner peripheral surface of the first vertical hole 822 according to fig. 2, and being formed by integral pressing as an outer cylindrical surface or an outer frustoconical surface without thereby limiting the outer shape thereof. Similarly, the innermost wall of the sleeve hollow cavity 148 is the longitudinal outer periphery of the first post 85 according to fig. 2, and is integrally pressed to form an inner cylindrical surface or an inner frustoconical surface without limiting the shape thereof.
Referring to fig. 3A-3C, in the preferred embodiment, the sleeve outermost wall 1462 is divided into multiple stages with different inner diameters (gradually wider) from the first end 142 along the longitudinal centerline G1, and includes: an annular outer narrow diameter section 1464, an annular outer wide diameter section 1466, and an outer annular saddle 1468 formed at the intersection of the outer narrow diameter section 1464 and the outer wide diameter section 1466. The outer diameter of the outer wide diameter section 1466 is greater than the outer diameter of the outer narrow diameter section 1464 but is approximately equal to the outer diameter of the outer annular saddle 1468. The sleeve innermost wall surface 1482 of the sleeve hollow cavity 148 for supporting the contents 100 and downwardly divided from the second end 144 along the longitudinal centerline G1 into multi-step sections of different (narrowing) inner diameters, comprising: an annular inner wide section 1484, an annular first inner narrow section 1486, a first inner ring saddle 1488 formed at the intersection of the inner wide section 1484 and the first inner narrow section 1486, an annular second inner narrow section 1489, and a second inner ring saddle 1490 formed at the intersection of the first inner narrow section 1486 and the second inner narrow section 1489. Since the inner diameter of the inner wide section 1484 is greater than the inner diameters of both the first inner narrow section 1486 and the second inner narrow section 1489 and is also greater than the inner diameters of both the first inner ring saddle 1488 and the second inner ring saddle 1490, but the inner diameter of the first inner narrow section 1486 is greater than the inner diameter of the second inner narrow section 1489 and the inner diameter of the first inner ring saddle 1488 is also greater than the inner diameter of the second inner ring saddle 1490, where both the second inner ring saddle 1490 and the second inner narrow section 1489 are just able to laterally support and more tightly restrict lateral movement of the contents 100 and the first inner ring saddle 1488 abuts the base 16 with a stop.
Referring to fig. 3A-3C, the cover 12 has a closed free top end 122, a closed end 124 opposite to the free top end 122, a cover standing wall 126 formed between the free top end 122 and the closed end 124 and surrounding the longitudinal center line G1, and a cover hollow cavity 128 formed between the free top end 122 and the closed end 124. The closed end 124 defines a closed opening 1242 communicating with the hollow cavity 128 of the cap and is configured to be disposed at the first end 142 of the sleeve member 14. The cover hollow cavity 128 forms a cover innermost wall surface 1282 facing the contents 100, and the cover vertical wall 126 has a cover outermost wall surface 1262. Based on the same manufacturing principle, the cover outermost wall surface 1262 of the cover standing wall 126 is the longitudinal inner circumferential surface of the first vertical hole 822 according to fig. 2, and is integrally pressed to form an outer cylindrical surface or an outer truncated cone surface without limiting the outer shape thereof. Similarly, the cover innermost wall surface 1282 of the cover hollow cavity 128 is the longitudinal outer peripheral surface of the first post 85 according to fig. 2, and is formed by integrally pressing an inner cylindrical surface or an inner truncated conical surface without limiting the outer shape thereof.

The abutting end 164 forms a carrying opening 1642 communicating with the hollow cavity 166 of the base and is configured to be disposed at the second end 144 of the sleeve member 14 for sealingly receiving the contents 100 between the cover 12 and the base 16. The base upright wall 168 has a base outermost wall 1682. Based on the same manufacturing principle, the base outermost wall 1682 of the base standing wall 168 is the longitudinal inner circumferential surface of the first vertical hole 822 according to fig. 2, and is integrally pressed to form an outer cylindrical surface or an outer truncated cone surface without limiting the outer shape thereof. Similarly, the innermost wall 1684 of the hollow base cavity 166 is the outer longitudinal surface of the first post 85 of fig. 2 and is integrally pressed to form an inner cylindrical surface or an inner frustoconical surface without limiting the shape thereof.

Preferably, after the cap body 12 and the sleeve member 14 are combined, if the longitudinal centerline G1 is taken as a reference line of relative position, the cap body 12 and the sleeve member 14 still each exhibit the corresponding positive draft angle Θ 1 (see fig. 3A).

The constituent elements of the cardboard container 20 of the second preferred embodiment also include: a cover 12, a sleeve 14 and a base 16, but the detailed structure and configuration of the cover 12, the sleeve 14 and the base 16 of the second preferred embodiment of fig. 4A-4C are different from those of the long cylindrical paper container 10 of the first preferred embodiment of fig. 3A-3C in that:
(1) in the second preferred embodiment illustrated in fig. 4A-4C, both the cover 12 and the sleeve 14 of the long cylindrical paper container 20 are respectively scooped up with wet plant fiber slurry by the first male mold 84 of the integrated automatic production machine (using wet fiber paper molding process) of the pulp molding process line 70 illustrated in fig. 2, so that the first male mold 84 and the first female mold 82 are closed to integrally press-mold the wet plant fiber slurry, but the base 16 can be replaced with an existing cylindrical paper tube to reduce the manufacturing cost, but not limited thereto; in other preferred embodiments, the cover 12, the sleeve 14 and the base 16 can still be integrally formed by pressing through the pulp molding process line 70 illustrated in fig. 2;

(3) Referring further to fig. 4A-4C, in the second preferred embodiment, when the abutting end 164 of the base 16 is disposed at the second end portion 144 (which is a closed end for longitudinally supporting the contents 100), since the inner diameter of the carrying opening 1642 of the abutting end 164 of the base 16 is larger than the outer diameter of the outermost wall 1462 of the sleeve 14, the second end portion 144 of the sleeve 14 enters the base hollow cavity 166 of the base 16 until the second end portion 144 of the sleeve 14 abuts against the inner wall surface of the free bottom end 162 of the base 16, wherein both the outermost wall 1462 of the sleeve 14 and the innermost wall 1684 of the base 16 are flat surfaces extending in the longitudinal direction, so that a face-to-face longitudinal close contact is formed between the outermost wall 1462 and the innermost wall 1684 of the base (and other permanent fixing devices may be further added therebetween) Such as glue) and because the height of the base standing wall 168 is less than the height of the sleeve standing wall 146, the first end 142 of the sleeve member 14 extends beyond the abutting end 164 of the base 16;

(5) referring further to fig. 4B, the cover standing wall 126 of the cover 12 has a transverse cross-sectional thickness greater than the transverse cross-sectional thickness of the base standing wall 168 and greater than the transverse cross-sectional thickness of the sleeve standing wall 146, but not limited thereto. For example, in other preferred embodiments, the overall configuration and dimensions of both the cover 12 and the base 14 may be identical.
Except for the above-mentioned several different structures, since the remaining structures, preparation and arrangement of the cover body 12, the sleeve member 14 and the base 16 of the cardboard long container 20 of the second preferred embodiment of fig. 4A to 4C are substantially the same as those of the cardboard long container 10 of the first preferred embodiment of fig. 3A to 3C, reference can be made to the above description of the components of the cardboard long container 10 of the first preferred embodiment of fig. 3A to 3C, and thus, the following description will not be repeated. For example, in FIG. 4B, when the cover 12, the sleeve member 14 and the base 16 are combined together to form the paper long cylindrical container 20, the paper long cylindrical container 20 has a container maximum height h2 parallel to the longitudinal centerline G1, a container maximum width w2 perpendicular to the longitudinal centerline G1 and a container aspect ratio r2 which is such that the container maximum height h2 is opposite to the container maximum width w 2; similarly, the container aspect ratio r2 is between 2 and 5.5 (i.e. h2/w2 is r2,5.5 is r2 is 2); preferably, when the height-width ratio r2 of the container is between 2 and 5.5, the maximum width w2 of the container is between 12 and 23 mm.
It should be noted that, in another modified embodiment based on the second preferred embodiment, the long-column paper container 20 can be assembled by only using the cover 12 and the base 16 without using the sleeve 14, wherein the lower half of the content 100 is permanently fixed in the base 16, the upper half of the content 100 is closely shielded by the cover hollow cavity 128 of the cover 12, and the upper half of the content 100 is directly in face-to-face loose fit with the cover innermost wall surface 1282 of the cover 12.
In addition, referring to fig. 5A to 5C, fig. 5A is a perspective view of a long cylindrical paper container 30 according to a third preferred embodiment of the present invention. The constituent elements of the cardboard long cylindrical container 30 of the third preferred embodiment also include: a cover 12, a sleeve 14 and a base 16, but the detailed structure and configuration of the cover 12, the sleeve 14 and the base 16 of the third preferred embodiment of fig. 5A-5C are different from those of the long cylindrical paper container 20 of the second preferred embodiment of fig. 4A-4C in that:
(1) after the integral press molding by the integrated automated manufacturing machine of the pulp molding process line 70 depicted in fig. 2, the respective release surfaces of each integral structure of the cover 12 and the base 16 form a positive draft angle Θ 1 (e.g., less than or equal to 1.5 degrees) with respect to the longitudinal centerline G1 (parallel to the longitudinal mold clamping centerline Y1 depicted in fig. 2), and the cover outermost wall surface 1262 of the cover 12 and the base outermost wall surface 1682 of the base 16 both form flat surfaces extending in the same direction. When the cover 12, the sleeve 14 and the base 16 are combined together to form the long cylindrical paper container 30 shown in fig. 4A, the cover 12 and the base 16 are configured in two truncated cones which are inverted in opposite phases and stacked up and down;
(2) referring to fig. 5A-5C, in the third preferred embodiment, the innermost wall surface 1684 of the base 16 is divided downward from the abutting end 164 along the longitudinal center line G1 into an annular inner wide section 1686, an annular inner narrow section 1688, and an inner annular saddle 1689 formed at the intersection of the inner wide section 1686 and the inner narrow section 1688;
when the abutting end 164 of the base 16 is disposed at the second end 144 of the sleeve member 14 (having a second opening 1442 for the longitudinal penetration of the contents 100), since the inner diameter of the bearing opening 1642 of the abutting end 164 of the base 16 is larger than the outer diameter of the outermost wall 1462 of the sleeve member 14, the second end 144 of the sleeve member 14 enters the base hollow cavity 166 of the base 16 through the bearing opening 1642 of the base 16 until the second end 144 is stopped on the inner annular saddle 1689 due to the outer diameter of the second end 144 of the sleeve member 14 being larger than the inner diameter of the inner annular saddle 1688 and equal to the inner diameter of the inner annular saddle 1689 of the base 16, i.e., the second end 144 cannot continuously enter the inner annular saddle 1688; meanwhile, since both the inner wide section 1686 of the base 16 and the sleeve outermost wall 1462 of the sleeve 14 are flat surfaces extending in the longitudinal direction, the inner wide section 1686 and the sleeve outermost wall 1462 are in close contact with each other in a face-to-face manner (other permanent fixing structures such as glue may be further added therebetween); because the height of the base standing wall 168 is smaller than the height of the sleeve standing wall 146, the first end 142 of the sleeve 14 extends out of the abutting end 164 of the base 16, so that when the cover 12 is covered with the sleeve 14, the first end 142 and the upper half of the content 100 are completely covered by the cover hollow cavity 128; and
(3) with further reference to fig. 5B, the lateral cross-sectional thickness of the cover standing wall 126 of the cover 12 is slightly equal to the lateral cross-sectional thickness of the inner wide diameter section 1686 of the base standing wall 168, but the lateral cross-sectional thickness of the inner narrow diameter section 1688 of the base standing wall 168 is greater than the lateral cross-sectional thickness of the sleeve standing wall 146 and the lateral cross-sectional thickness of the cover standing wall 126.
Except for the above-mentioned several different structures, since the remaining structures, preparation and arrangement of the cover body 12, the sleeve member 14 and the base 16 of the paper long cylindrical container 30 of the third preferred embodiment of fig. 5A-5C are substantially the same as those of the paper long cylindrical container 20 of the second preferred embodiment of fig. 3A-3C, reference can be made to the above description of the components of the paper long cylindrical container 20 of the second preferred embodiment of fig. 4A-4C, and thus, the following description will not be repeated. For example, in fig. 5B, when the cover 12, the sleeve member 14 and the base 16 are combined together to form the paper long-column container 30, the paper long-column container 30 has a container maximum height h2 parallel to the longitudinal centerline G1, a container maximum width w2 perpendicular to the longitudinal centerline G1, and a container aspect ratio r2 which makes the container maximum height h2 relative to the container maximum width w 2; similarly, the container aspect ratio r2 is between 2 and 5.5 (i.e. h2/w2 is r2,5.5 is r2 is 2); preferably, when the height-width ratio r2 of the container is between 2 and 5.5, the maximum width w2 of the container is between 12 and 23 mm.
It should be noted that, in another modified embodiment based on the third preferred embodiment, the cardboard container 30 can be assembled by only the cover 12 and the base 16 without using the sleeve 14, and the overall structure and size of the cover 12 and the base 16 are completely the same, wherein the lower half of the content 100 is permanently fixed in the base 16, the upper half of the content 100 is closely shielded by the cover 12, and the upper half of the content 100 is directly in face-to-face loose fit with the innermost cover wall surface 1282 of the cover 12.
Referring to fig. 2 and fig. 6A to 6C, fig. 6A is a perspective view of a long cylindrical paper container 40 according to a fourth preferred embodiment of the present invention. The constituent elements of the cardboard container 40 of the fourth preferred embodiment include only: a cover 12 and a sleeve 14, but the detailed structure and configuration of the cover 12 and the sleeve 14 of the fourth preferred embodiment of fig. 6A-6C are different from those of the cover 12 and the sleeve 14 of the long cylindrical paper container 30 of the third preferred embodiment of fig. 5A-5C in that:
(1) referring to fig. 6A-6C, in the fourth preferred embodiment, the long-column paper container 40 can be assembled only by the cover 12 and the sleeve 14 without using the base 16 as shown in fig. 5A, wherein the middle portion (e.g., the groove 109) of the content 100 is permanently fastened to the periphery of the first opening 1422 of the first end 142 of the sleeve 14 to limit the movement of the content 100 in different directions, and the upper half of the content 100 penetrates the first opening 1422 upward and is blocked by the cavity 128 of the cover 12.
(2) Referring further to fig. 2 and fig. 6A-6C, in the fourth preferred embodiment, since both the cover 12 and the sleeve member 14 are scooped up wet plant fiber slurry by the first male mold 84 of the integrated automatic production machine (using wet fiber paper molding process) of the pulp molding process line 70 depicted in fig. 2, and the first male mold 84 and the first female mold 82 are clamped to integrally press and form the wet plant fiber slurry, the corresponding release surfaces of each integral structure of the cover 1 and the sleeve member 14 form a positive draft angle Θ 2 (e.g., less than or equal to 2 degrees) with respect to the longitudinal centerline G1 (parallel to the longitudinal clamping centerline Y1 depicted in fig. 2), and the cover outermost wall surface 1262 of the cover 12 and the sleeve outermost wall 1462 of the sleeve member 14 form flat curved surfaces extending outward toward the same inclination until the respective flat curved surfaces extend to the same inclination until the respective flat curved surfaces are clamped to the same inclination Terminating in a capped end 124 and a second end 144. In the fourth preferred embodiment, after the wet fiber paper molding process, the cover body outermost wall surface 1262 and the opposite cover body innermost wall surface 1282 both form a round-head conical surface, and the sleeve outermost wall surface 1462 and the opposite sleeve innermost wall surface 1482 both form a truncated conical surface, but the shape thereof is not limited thereto;

(3) referring further to fig. 6A-6C, in the fourth preferred embodiment, the innermost wall 1282 of the cover is divided from the free top end 122 thereof along the longitudinal centerline G1 into a conical inner narrow-diameter section 1284, an annular inner wide-diameter section 1286, and a first outer annular saddle 1288 formed between the end of the inner wide-diameter section 1286 and the capping end 124. The first outer annular saddle 1288 is a transversely extending baffle. The outwardly extending flat curved surface of the sleeve outermost wall 1462 of the sleeve 14 includes a second outer annular saddle section 1488, which second outer annular saddle section 1488 is a transversely extending baffle.
When the cap end 124 of the cap 12 is disposed at the second end 144 of the sleeve member 14, the first end 142 of the sleeve member 12 enters the cap hollow cavity 128 through the cap opening 1242, wherein the inner wide section 1286 and the sleeve outermost wall 1462 form a close-to-close contact (loose fit) between the inner wide section 1286 and the sleeve outermost wall 1462 (including the first and second outer ring saddles 1288, 1488) due to the flat curved surfaces extending outward at the same slope as both the inner wide section 1286 and the sleeve outermost wall 1462 until terminating in the two laterally extending first and second outer ring saddles 1288, 1488, respectively, and the second end 144 and the second outer ring saddle 1288 are stopped outside the bottom 1488 of the first outer ring because the outer diameter of the second end 144 is larger than the inner diameter of the cap opening 1242, that is, the second outer annular saddle 1488 will sit longitudinally against the bottom of the first outer annular saddle 1288.
Except for the above-mentioned several different structures, since the remaining structures of the cover body 12 and the sleeve member 14 of the cardboard container 40 of the fourth preferred embodiment of fig. 6A to 6C are substantially the same as those of the cardboard container 30 of the third preferred embodiment of fig. 5A to 5C, reference can be made to the above description of the components of the cardboard container 30 of the third preferred embodiment of fig. 5A to 5C, and thus, the following description will not be repeated.

The constituent elements of the cardboard container 50 of the fifth preferred embodiment also include: a cover 12, a sleeve 14 and a base 16, but the detailed structure and configuration of the cover 12, the sleeve 14 and the base 16 of the fifth preferred embodiment of fig. 7A to 7D are different from those of the long cylindrical paper container 10 of the first preferred embodiment of fig. 3A to 3C in that:
