Pet Carrier Bag with Quick-Absorbent Urine Pad and pH Test Strips

Patent & Production

At a glance

What the claims cover, in plain language

Claim 1 - defines a pet carrying bag with a specific bottom adsorption pad system. The bag body has disassembly buttons for the hand strap and a locking strap with a transparent cover. The bottom pad contains a disassembly strip holding water-absorbing pills. These pills include a sponge with grooves, a deodorizing ring, and are connected to shaping balls and water-absorbing balls via shafts. The shafts feature color-developing axes with detection test papers.

Claims 2-6 - specify the materials and sub-components: the sponge contains activated carbon; the deodorizing ring contains biological enzymes; the shaping ball contains odor inhibitors and plant essential oils in fiber beads; the test papers are pH indicators arranged in a cone-like structure on the shafts.

Claims 7-9 - describe the bag’s “8”-shaped cross-section, the removable nature of the locking strap via fastening buttons, and the spiral configuration of the pull-out belt used to remove the absorbent pills.

This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.

What this means for US production

This patent was filed in China and is currently in force. Making or selling this specific design in China requires the owner’s permission. The public record shows no US counterpart. Therefore, this patent does not restrict manufacturing or sales in the United States based on its own terms. However, freedom-to-operate analysis is still required due to other potential IP.

Two points to settle early:

• Other patents may exist. The field of pet hygiene and travel accessories is active. While this specific combination of pH testing and absorbent pills appears unique to this filing, broader concepts of absorbent pet pads or carrier structures may be covered by other US patents. We recommend a freedom-to-operate (FTO) review focusing on the absorbent mechanism and the integrated testing display.
• Material Safety. Since the device involves close contact with animals and potentially ingested materials (if chewed), ensuring all components meet US safety standards for pet products is critical.

Customization and manufacturing

What can be customized

Things to plan for (US market)

• Consumer Product Safety Commission (CPSC): General safety requirements for consumer goods, particularly regarding small parts if accessible to children or pets.
• State Laws: Some states have specific regulations for pet product labeling and safety.
• California Prop 65: If using certain plastics or dyes, warning labels may be required if chemicals are present above safe harbor limits.
• FDA Guidelines: While not a medical device, if marketing claims imply diagnostic use, FDA scrutiny may apply. Stick to general wellness/hygiene claims unless validated.

How a project runs

1. Inquiry - Define target pet size, desired absorbency level, and quantity.
2. Design - Finalize bag dimensions, pad layout, and test paper placement.
3. Prototype - Create samples using 3D-printed structural parts and sewn fabric bodies.
4. Testing - Conduct bite resistance tests, absorption capacity trials, and material safety reviews.
5. Production - Injection mold plastic components, sew fabric bodies, assemble pads, and pack.

Quantities & timeline

Molds for the plastic pills and shafts take several weeks. Sewing and assembly lines scale with order volume. Material sourcing for specialized enzymes and test papers adds lead time. Send us your target pet size, estimated monthly volume, and desired retail price point and we will reply with options.

Production notes

Tooling and process

Injection molding is likely used for the hard plastic components like the connecting shafts and shaping balls. TPE overmolding might be applied to create soft grips or seals on the disassembly buttons. The bag body itself requires sewing operations for the fabric panels. Assembly involves snap-fitting the absorbent pills into the pad and screwing or knotting the straps to the body.

Cost drivers

Part count is typically significant due to the multi-component absorbent system. Bite-resistant material selection increases raw material costs. Non-toxic material certification adds administrative overhead. Cleaning design complexity affects mold tooling costs. Packaging must accommodate the bulky pad system.

Prototyping path

We would typically start with a 3D-printed sample of the rigid parts to verify fit. Obtain material safety certificates for all plastics and fabrics. Perform bite and pull tests on assembled prototypes. Create a functional sample with actual absorbent materials for performance validation before tooling.

What we would change before tooling

We would simplify the connection between the shaft and the test paper to reduce assembly time. The spiral pull-out belt might be redesigned as a straight tab for easier manufacturing. Ensuring the transparent cover is securely sealed against urine leakage is a priority.

Common failure points

Small parts detaching from the shafts pose a choking hazard. Bite penetration could damage the internal enzyme rings. Dirt trapped in seams of the fabric body reduces hygiene. Fastener corrosion from urine exposure is a risk. Seam strength must withstand the weight of a struggling animal.

Frequently asked questions

How does the pH test work?

The connecting shafts inside the absorbent pad hold pH detection test papers. When urine contacts these papers, they change color. You can see this change through the transparent cover on the locking strap, giving a visual indication of the urine’s acidity.

Is the absorbent pad reusable?

The water-absorbing pills are designed to be removed and replaced. The pull-out belt allows you to extract saturated pills from the pad. The bag body and pad structure remain, but the internal absorbent components are consumables.

What materials are used for odor control?

According to the patent, the system uses activated carbon stored inside the water-absorbing sponge and biological enzymes within the deodorizing rings. Additionally, fiber beads containing plant essential oils are part of the shaping ball assembly.

Can my pet chew the absorbent pills?

The pills are located inside the bottom pad, separated from the main compartment. However, if the bag is damaged, access might be possible. We recommend using bite-resistant materials for the outer shell and supervising pets to prevent chewing on the carrier itself.

How do I clean the bag?

The main bag body is likely made of fabric that can be wiped down or washed according to the manufacturer’s instructions. The bottom pad assembly should be cleaned by removing the used absorbent pills and wiping the surface. Regular inspection of the seams is advised.

Are the test papers accurate for diagnosis?

The patent describes these as pH detection test papers for monitoring urine status. They provide a general indicator of acidity. For serious medical concerns, consult a veterinarian. These are not clinical diagnostic devices.

Can this design be made and sold in the US?

The patent was filed in China and is in force there. The public record shows no US counterpart. Therefore, this specific patent does not restrict manufacturing or selling in the US. However, other US patents may exist in the pet accessory space, so a freedom-to-operate review is recommended.

Are you affiliated with the patent owner?

No. IP2M is an independent design and manufacturing service working from the public patent document.
