PRIOR APPLICATIONS

[0001] This application claims the benefit of two U.S. Provisional Patent Applications, both of which are incorporated by reference in their entirety: [0002] 1) Application No. 63/257,074, filed on October 18, 2021.

[0003] 2) Application No. 63/330,775, filed on April 14, 2022.

FIELD OF THE DISCLOSURE

[0004] The present disclosure relates generally to a single-use child-safety blister packaging that may be suitable for securing material that is not appropriate for children’s use.

BACKGROUND

[0005] Designing and implementing child safety packaging as a single use is necessary to comply with certain applicable government regulations, including the Code of Federal Regulations (CFR) Title 16, Part 1700.20 for Poison Prevention Packaging.

[0006] In this regard, “Child-resistant packaging” means packaging that is designed and constructed to be significantly difficult for children under 5 years of age to open or obtain a toxic or harmful amount of the substance contained therein within a reasonable time, and that is not difficult for normal adults to use properly.

SUMMARY

[0007] To meet the goal of child-resistant packaging, a blister card with one preformed cavity, having dimensions of approximately 5" x 3" is used. The blister card is constructed of weight 350 g/m 2 and/or 16-point solid bleached board (SBS) comprised of polyolefin (PO) layer, a tear resistant layer, and a heat- sealable polymer layer. The blister is made of polyvinyl chloride (PVC) or paper.

DETAILED DESCRIPTION

[0014] I. INTRODUCTION

[0015] A single-use child safety packaging may consist of: [0016] 1. An approximately 350 g/m 2 and/or 16-point solid bleached board sulphate (SBS) blister card comprised of a polyolefin (PO) layer, a tear-resistant layer, and a heat-sealable polymer layer; and

[0017] 2. A blister made of polyvinyl chloride (PVC). Alternatively, the blister may be made of paper. Alternatively, the blister may comprise SBS comprised of a PO layer, a tear-resistant layer, and a heat-sealable polymer layer. The

[0018] Features of this packaging may include:

[0019] - The rigidity of paperboard and the tear-resistance of lamination combines for assembly performance of trap seal blister packaging and provides superior resistance to tear initiation.

[0020] - The heat seal compatibility consistently seals to a wide variety of thermoformed blister materials, including one or more of Amorphous Polyethylene Terephthalate (APET), Recycled Polyethylene Terephthalate (RPET), Polyethylene Terephthalate Glycol (PETG), Recycled Polyethylene Terephthalate Glycol (RPETG), PVC and Polyactic Acid (PLA).

[0021] - Low-temperature sealing yields increased line speed, minimized risk of seal product damage and reduced ink degradation.

[0022] - Polymer coat-weight uniformity provides improved efficiencies and maximum throughput on high-speed filling equipment.

[0023] The security of the packaging is further ensured when a heat-activated seal is applied to the SBS during the printing process. When heat is applied to seal the blister within the blister card, this application activates the heat-sealable polymer layer to secure the blister within the packaging.

[0024] The packaging may be used to ensure that cannabis-related products contained therein are child proof, as may be required by law.

[0025] II. PHYSICAL CHARACTERISTICS

[0064] III. ASSEMBLY

[0065] In the case where the blister is a paper blister insert 200, it is possible to assemble a paper blister insert into a blister card. Figures 3A-3I show an exemplary sequence of such an assembly.

[0066] Figure 3A shows a presser with a presser backside 302A installed on a base 305.

[0067] Figure 3B shows a presser with a presser frontside 302B and a presser puncher 302C removed from the base 305.

[0068] Figure 3C shows the presser receptacle 320 within the base 305 that is visible when the presser is removed.

[0069] Figure 3D shows the inner side 340A of a blister card on the base 305 with its blister hole 355 centered over the pressure receptacle 320 (not shown).

[0070] Figure 3E shows the inner side 340A of a blister card on the base 305 with its blister hole 355 (not shown) centered over the pressure receptacle 320 (not shown). The blister 345 is centered over the blister hole 355 (not shown).

[0071] Figure 3F shows the presser with a presser backside 302A re-installed on the base 305. Using the pressure puncher 302C (not shown), the blister 345 (not shown) is assembled by being pushed through the blister hole 355 (not shown) and into the presser receptacle 320 (not shown).

[0072] Figure 3G shows, with the presser removed, the inner side of the now- assembled blister 350A is inserted into the inner side 340A of the blister card on the base 305.

[0073] Figure 3H shows the outer side of the now-assembled blister 350B as pushed through the outer side 340B of the blister card.

[0074] The material to be protected by the packaging is inserted into the inner side of the now-assembled blister. The blister card is then folded over and both sides of the blister card are secured to each other to secure the blister and the materials contained within the blister. [0075] Figure 31 shows the outer side of the now-assembled and secured blister as pushed through the now-assembled outer side 340B of the blister card.

[0076] The sequence shown is exemplary, and may be altered to be accomplished by hand or mass-produced by a machine process.

[0077] IV. TESTING

[0078] The following embodiment of a one-time use blister pack was subject to a testing to ensure it qualified as child resistant. Since the blister pack is a one-time- use product, durability testing was not performed.

[0079] A blister card with one pre-formed cavity, having dimensions of approximately 5" x 3" was used. The blister card is constructed of 350 g/m 2 solid bleached board (SBS) comprised of polyolefin (PO) layer, a tear resistant layer, and a heat-sealable polymer layer. The blister is made of polyvinyl chloride (PVC) or paper.

[0080] The protocols for the evaluation of packaging for poison prevention (CFR Title 16, Part 1700.20) were generally adhered to for this study. Participants were given a package containing an empty vape cartridge. Test Administrators asked all senior adults and children to open the package. Senior adults were provided with scissors.

[0081] In the study, 50 children (42 to 51 months of age) and 100 senior adults (50 to 70 years old, 70% female) were employed. Per testing protocol, children were allowed up to five minutes to open the package in each of two testing periods. A test is considered failed when any child opens the blister pack or gains access to its contents within the time allotted. None of the children were able to open the blister pack during the full ten-minute testing period, a 0% failure rate and a child-resistant effectiveness of 100% for the entire testing period. These results exceed CFR Title 16, Part 1700.20 minimum requirements.

[0082] In contrast, all senior adult participants were successful in opening the blister pack during the time frame allotted. Per testing protocol, to pass the first testing period, participants are allowed up to five minutes to open and reclose the package. To pass the second testing period, participants are allowed one minute to open and reclose the package. Participants who opened and reclosed the package in under one minute in the first testing period were not tested a second time. A senior adult test is considered failed when any adult is unable to open and reclose the package within five minutes during the first test period or is unable to open and reclose the package within one minute during the second test period. The senior adult use effectiveness was calculated at 100%, exceeding CFR Title 16, Part 1700.20 minimum requirements.

[0083] The results of the testing of the blister pack indicate the package fulfills the Consumer Product Safety Commission's (CPSC) protocol and standards for Poison Prevention Packaging as required by the Code of Federal Regulations (CFR) Title 16, Part 1700.20 in effect in 2021.
