A doctor kit is a case full of small mouldings, and its cost is decided by how those parts nest. Buyers who treat the set as one drawing end up with a case that rattles, instruments that fall out when the latch opens, and a pack size that eats the retail margin. We mould doctor kits as a nesting problem first: every instrument gets a pocket in a moulded insert, the insert gets a home in the clamshell, and the clamshell is dimensioned around the packed insert rather than around the instruments loose.
The programme covers the standard preschool set — stethoscope, thermometer, syringe without needle, blood pressure cuff, otoscope, reflex hammer, forceps, scissors and a tray of pill bottles — plus the case that carries them.
Clamshell case and insert
The case is a two-half clamshell in rigid PP with a snap latch and a moulded carry handle. The insert is a separate moulding with a pocket per instrument, vacuum-formed only where a shape is too complex to mould; moulded inserts hold shape after a season of being sat on. Instrument retention is designed so a pocket grips the part by a moulded rib rather than by friction alone, so the set survives being carried by the handle upside down.
Instrument construction
Instruments follow a rigid-core, soft-tip construction: a PP or ABS handle for stiffness, with TPE moulded or assembled onto the contact end. The stethoscope is the hardest part of the set — the chest piece, tubing and binaurals are specified as three components with a tubing material that stays flexible in cold, because a stiff tube makes the toy unusable in a winter classroom. The syringe is moulded without a needle with the tip geometry that cannot accept one, and this is stated in the specification rather than left to inspection.
- One moulded pocket per instrument, retention by moulded rib
- Rigid-core soft-tip construction across the instrument set
- Stethoscope tubing specified for low-temperature flexibility
- Syringe tip geometry cannot accept a needle
Print and decoration
Decoration runs tampo print on the instrument faces and a printed card insert in the case lid. Where the set carries dials or gauges, the dial face is printed in-register to a moulded mark so the needle reads against a real scale rather than a graphic alone. All printing is specified lead-free, and the ink system is declared on the compliance sheet the buyer submits to their laboratory.
Safety and compliance
Preschool sets are produced to EN71-1/2/3 and ASTM F963 with the age grade stated on the pack. Small-parts testing is run on first articles with the parts tested in their as-shipped condition — assembled, not separated — because the question the standard asks is whether the part comes off in a child's hand. Warning text is printed on the pack and moulded into the case where the buyer's artwork allows.

Set economics
The case and insert tools are the fixed cost of the programme; instruments are amortised across the set and its variants. The efficient structure is one case platform carrying three instrument tiers — an eight-piece starter, a fifteen-piece standard and a twenty-piece deluxe — which is how we quote the programme: one platform, three bills of materials.
