Description

Technical Field

[0001] The present disclosure relates to packaging, and in particular to fiber- or pulp-based containers and closures. Background Art

[0002] Containers formed based on fibres or pulp are formed from two moulded halves. This can lead to problems with sealing the contents in the container, i.e. without the contents leaking out of the container.

[0003] Additionally, fiber or pulp based containers are not adequate in terms of manufacturing tolerances. For example, plastic based containers have a tolerance of + / - 7 thousandths of an inch, while fiber or pulp based containers have a tolerance of + / - 70 thousandths of an inch, a tolerance factor that is 10 times less precise. Therefore, steps must be taken to address closure and sealing issues. Summary of the invention

[0004] Disclosed herein are methods and apparatus for achieving fiber- or pulp-based containers, closures, and packaging that can contain contents without leakage therefrom.

[0005] In one aspect, a container includes a closure including a closed sealing surface, a molded fiber container body, and a collar bonded to the molded fiber container body, the collar being configured to provide a sealing surface corresponding to the closed sealing surface to seal the container when the closure is attached to the bonded collar and molded fiber container body.

[0006] In another aspect, a container includes a pair of molded-fiber container halves and an interconnection mechanism configured to join the pair of container halves to form a molded-fiber container body. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Reference now Figure 1-Figure 4 , and refer to Figure 5- Fig.11 With the applicable interlocking mechanism described in, the container halves 1100 and 1150 can be mechanically joined as described herein to form a container body. In some embodiments, the edges of the container halves 1100 and 1150 can be coated with a sealant material as described herein. Thus, the mechanical joining process also causes the sealant material to adhere. In these cases, no further action is required to seal the resulting container to prevent leakage. In some embodiments, as described herein, the tape 1400 is bonded to the external or internal seam or joint area to prevent leakage. The tape 1400 extends from the neck 1110 downward to one side of the container 1000, across the base 1130, upward to the opposite side of the container 1000, and back to the neck 1110.

[0068] The collar 1200 is bonded to the neck 1110 of the container 1000 using a joining process. In some embodiments, the collar 1200 has an S-shaped profile or cross-section. The collar 1200 may include a first horizontal section 1210, a vertical section 1220, and a second horizontal section 1230. The first horizontal section 1210 may provide a sealing surface 1212 for the closure 1300. In some embodiments, after the contents are placed in the container 1000, a foil, paper liner, or similar layer (collectively referred to as a "paper liner") may be bonded to the first horizontal section 1210. Containers molded from fibers, pulp, and / or similar materials lack a smooth sealable surface against which the paper liner and / or closure 1300 may seal. In some embodiments, the vertical section 1220 may provide a secondary or redundant sealing surface for the closure 1300 described herein. In some embodiments, the second horizontal section 1230 can implement a latching mechanism for the closure 1300 as described herein.

Fig.13 is a cross-sectional view taken along a seam or join area of ​​a container 12000 according to an embodiment. Fig.14 is a cross-sectional view taken along a seam of a container 12000 according to an embodiment. Fig.15 is an exploded cross-sectional view taken along a seam of a container 12000 according to an embodiment. Fig.16 1 is a cross-sectional top view of a container 12000 according to an embodiment. The container 12000 includes appropriate and applicable information about the container 12000 as appropriate and applicable to the context. Figure 1-Figure 11 Description.

[0070] Container 12000 includes container body 12100, collar 12200, closure 12300, and tape 12400. In some embodiments, tape 12400 is not required, depending on the engagement mechanism used, as described herein with respect to Figure 1-Figure 11 12100, which is used to connect the container halves that constitute the container body 12100. The container body 12100, the collar 12200 and the closure 12300 can each be a structure formed by a structural molding material using the structural molding process described herein. The container body 12100 and the collar 12200 are combined as described herein. The profile of the closure 12300 generally follows the combined combination of the container body 12100 and the collar 12200 or matches it. The container body 12100 includes a pair of walls 12110 and 12112. When the closure 12300 is latched to the container body 12100, the walls 12110 and 12112 can provide diameter alignment between the container body 12100 and the closure 12300.

[0071] As described herein, the collar 12200 has an S-shaped profile or cross-section that includes a first horizontal segment 12210, a vertical segment 12220, and a second horizontal segment 12230. The closure 12300 includes an intermediate latch mechanism 12310, a first sealing surface 12320, a second or redundant sealing surface 12330, and a finger grip 12340. The first sealing surface 12320 is configured to cooperate with the first horizontal segment 12210 to provide a first seal (i.e., a closed container configuration) when the closure 12300 is latched or attached to the container body 12100. The second or redundant sealing surface 12330 is configured to cooperate with the vertical segment 12220 when the closure 12300 is latched to the container body 12100. The inner surface of the second or redundant sealing surface 12330 is configured to radially seal with the outer surface of the vertical segment 12220. In some embodiments, the closure 12300 can exclude a second or redundant sealing surface 12330 (e.g., Figure 3 shown).

[0072] The intermediate latch mechanism 12310 has inwardly contoured, recessed or depressed sections (collectively referred to as "intermediate latch sections") 12312 and 12314 in the closure 12300 that are configured to latch with the container body 12100 by fitting below the second horizontal section 12230 and above the respective walls 12110 and 12112 when the closure 12320 is latched to the container body 12100. In some embodiments, the closure 12300 can be opened or unlocked from the container body 12100 (i.e., open container configuration) by squeezing or pinching the finger grips 12340 toward each other. This causes the intermediate latch sections 12312 and 12314 to disengage, unlock or move (collectively referred to as "unlock") from the container body 12100 so that the closure 12300 can be lifted without the intermediate latch sections 12312 and 12344 striking the second horizontal section 12230. In some embodiments, the closure 12300 on the container body 12100 is twisted so that the intermediate latch sections 12312 and 12314 leave the container body 12100 in a cam or cantilever manner, and then the closure 12300 is lifted upward and away from the container body 12100, in which way the closure 12300 can be opened or unlocked from the container body 12100.

In some embodiments, tape 17400 is not required, depending on the engagement mechanism used, as described herein with respect to Figure 1-Figure 11 17100, which is used to connect the container halves that constitute the container body 17100. The container body 17100, the collar 17200 and the closure 17300 can each be a structure formed by a structural molding material using the structural molding process described herein. The container body 17100 and the collar 17200 are combined as described herein. The profile of the closure 17300 generally follows the combined combination of the container body 17100 and the collar 17200 or matches it. The container body 17100 includes a pair of walls 17110 and 17112. When the closure 17300 is latched to the container body 17100, the walls 17110 and 17112 can provide a diameter alignment between the container body 17100 and the closure 17300.

[0075] As described herein, the collar 17200 has an S-shaped profile or cross-section that includes a first horizontal segment 17210, a vertical segment 17220, and a second horizontal segment 17230. The closure 17300 includes a bottom latch mechanism 17310, a first sealing surface 17320, a second or redundant sealing surface 17330, and a finger grip 17340. The first sealing surface 17320 is configured to cooperate with the first horizontal segment 17210 to provide a first seal (i.e., a closed container configuration) when the closure 17300 is latched or attached to the container body 17100. The second or redundant sealing surface 17330 is configured to cooperate with the vertical segment 17220 when the closure 17300 is latched onto the container body 17100. The inner surface of the second or redundant sealing surface 17330 is configured to radially seal with the outer surface of the vertical segment 17220. In some embodiments, the closure 17300 can exclude a second or redundant sealing surface 17330 (e.g., Figure 3 shown).

[0076] The bottom latch mechanism 17310 is implemented by inwardly contoured, recessed or depressed sections (collectively referred to as "bottom latch sections") 17312 and 17314 of the closure 12700, which are configured to latch with the container body 17100 by fitting or cooperating with the corresponding wall bottom latch portions 17111 and 17113 of the corresponding walls 17110 and 17112 when the closure 17300 is latched to the container body 17100.
