Does this dataset prove every JR DELIPACK container is leak-proof?

No. Results apply only to the tested samples, model configurations, food conditions and observed runs. Commercial suitability must be confirmed for the selected SKU and intended use.

How many samples were tested?

Three samples were drawn for each tested model. The public source record does not yet enumerate every model code, so no unsupported aggregate sample total is published.

What counted as a pass?

The leakage acceptance threshold was zero visible leakage. Unrecorded numeric parameters such as exact fill temperature, shake count and drop height are not invented.

Leak & lid-fit test data for soup cups and sauce cups.

A buyer-facing record of what was tested, what was observed and which numeric parameters were not captured. The result is intentionally narrower than a catalogue claim.

SCOPE & ACCEPTANCE

What the result covers.

The public record covers sampled soup-cup and sauce-cup models. Each tested model used three samples. The pass threshold for leakage was zero visible leakage.

Foods

Hot soup, oily food and sauces were used to avoid treating room-temperature water as a substitute for the intended menu.

Handling

Inversion, tilt, e-bike delivery, repeated manual shaking and a normal table-height drop were included.

Reheating

Microwave reheating was observed as an application condition, not as a regulatory migration or universal microwave-safety certification.

RESULT MATRIX

Observed outcome and data limits.

“Pass” means the zero-visible-leakage criterion was met in the reported run. It does not create an all-SKU or all-use leak-proof claim.

Test	Recorded condition	Reported result	Public data limit
High-temperature fill	Hot soup, oily food and sauce	Leakage criterion met in the reported runs	Exact fill temperature was not captured in the current public record.
24-hour inversion	Closed sample held fully inverted	PASS - zero visible dripping	Duration is owner-confirmed; model-level timestamps are not public.
45° and 90° tilt	Two handling angles after closure	PASS - zero visible leakage	Dwell time at each angle was not instrumented in the public record.
Delivery vibration	E-bike delivery run plus repeated manual shaking	PASS - no leakage reported in the observed run	Route, duration and shake count were not numerically logged.
Normal table-height drop	Closed container dropped from ordinary table height	PASS - no spill reported	Exact height and impact surface were not instrumented.
Microwave reheating	Closed-system observation after reheating	Leakage criterion met in the reported run	Power, time and food core temperature are not public; this is not a migration or safety certification.

REPRODUCTION METHOD

How a buyer can repeat the screen.

01Identify the exact base and lid model; draw three samples from that model.
02Use the intended hot soup, oily food or sauce and record the numeric fill temperature.
03Close using the normal kitchen workflow; verify full rim engagement.
04Run 45°/90° tilt, 24-hour inversion, transport vibration and drop checks.
05Photograph every sample before and after; count any visible drip as a failure.

FAQ

What this page does not claim.

Does this prove every container is leak-proof?

No. It documents sampled soup-cup and sauce-cup models under reported conditions. Confirm the selected SKU, food, fill level and delivery workflow.

Why are some numeric fields marked unavailable?

The current public record does not contain an exact fill temperature, shake count, route duration or measured drop height. Publishing “not recorded” is more credible than reconstructing a number.

Where is the buyer test checklist?

Use the separate Leak & Lid-Fit Checklist for test design and purchasing controls. This page remains the result dataset so the two pages do not compete for the same search intent.

BUYER VALIDATION

Need the test repeated for your food and delivery route?

Send the target SKU or capacity, food type, fill temperature, destination and expected travel time.
