Operculum: pair of rigid plates covering and protecting the gills of a fish.
Ostracoderms had separate pharyngeal gill pouches along the side of the head, which were permanently open with no protective operculum.
Instead of a gill cover, the brook lamprey has a row of 7 small breathing holes immediately behind each eye.
Neritidae, common name the nerites, is a taxonomic family of small- to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum.
The ostracoderms had separate pharyngeal gill pouches along the side of the head, which were permanently open with no protective operculum.
The invention relates to a station for uncapping (100) a receptacle (10) comprising a body (12) in which a plurality of adjacent holes (14), initially sealed by a cap (18), are formed.
When the water content is less than 20%, the bees seal the cell with a wax capping.
When the water content is less than 20% the bees seal the cell with a wax capping: the honey is now considered 'ripe' and will not ferment.
The PET bottle ensures the coconut milk 12-month shelf life without any sterilised aluminium foil before capping because the tightness between the bottle neck and the cap is very safe.
The final result is a wedge-shaped pack with an inner plastic sealing and an oxygen barrier label.
The closure (21) is characterized by the absence of a second liner between the top (54) of the cap (21) and the foil liner (78).
A cap closure (6) is arranged over the open mouth.
With the exception of the barrier, the cap is of unitary construction.
A container, cap and seal assembly (10) comprises a container base (20), a cap (30) and a seal (40) engagable with the container base.
Each projection is configured for releasably engaging a cap.
Alternatively, a double-spiralled grooved is formed in a base disc and closed off by a snap-on cover disc.
A mold including a unique movable gate is also disclosed herein.
What is disclosed is an artificial cranial operculum (1) to replace a bone operculum (2) removed from a cranial theca (7) during a neurosurgical procedure that involves a craniotomy.
A valve assembly with a multiple-component valve plug (21) is disclosed.
The foil liner (78) includes a tab (80) for removal of the seal disc (78) from the neck (22).
A cover is disposed over the opening and a removable cover is disposed over the aperture.
The cover member includes a lid member and a support member and the lid member is openable relative to the support member about a hinge.
Seal device with partial opening for covering the open surface (5) of a container (1) by means of a peal-off seal (10).
The test sensor packaging container comprises a housing, a first foil cover, and a second foil cover.
The operculum is composed of four bones; the opercle, preopercle, interopercle, and subopercle.
A rotatable mount for a blowout preventer bonnet (14).
A flapper valve (22) may be used as another seal.
The invention also relates to a method for producing such a lid.
A removable protective seal (11) covers these valves (7).
The outlet opening is closed with a first removable or severable seal (150), and the actuation opening is closed with a second seal (160).
An overseal (55) is positioned over the spout.
A rotating valve plug (17) is pivoted on the rotating shaft (9).
The blister pack has at least one blister and a lid foil.
Alternatively, the recesses (106) are closed by a cover body (132).
A nestable container (10) has a lid (12) for rotation mounting thereon.
