The cutting member is fixed to the body portion and comprises an elongated configuration and is aligned along a central longitudinal axis of the body portion. The cutting member extends downward from the neck portion and body portion and comprises a cutting edge adapted to penetrate a portion of a package.

A secure specimen sample bottle includes a base container for receiving a specimen. The base container has a plurality of locking protrusions formed along an inner surface of the base receptacle. A bottle includes a lock ring that has an upright spire structure that has a closed top end and the opposing open bottom end including a plurality of flexible fins that are configured to interlockingly mate with the locking protrusions so as to prevent removal of the lock ring relative to the base container upon engagement of the flexible fins to the locking protrusions. A removable cap is coupled to the lock ring.

A bag cutter for opening a sealed package using at least one of a blade and a piercer. Preferably, at least one blade is disposed partially within a cutout of an arm in a manner that exposes an edge of the blade. A piercer can comprise an extension of a cutout edge or be located on any other suitable portion of an arm. Another blade can be provided that is substantially perpendicular to the blade within a cutout, and juxtaposable against a cutting surface.

An assembly for cutting the packets like by trimming off an end portion of a closed edge of said packet using cutting means. It uses at least one trimming blade (1) and plastic body (2), where the blades are movable in a reciprocating manner one against the packet top which is inserted into the machine body.

An apparatus and methods of opening containers which permit the user to remove the entire flat upper planar surface. The apparatus and methods, incorporate a platform with a plurality of arms operatively coupled to respective blade members that engage inner circumferential edge of a container by folding the edges inward. The blade members and arms are operatively coupled to a lever and rotate outward when the lever is compressed. The inventors have determined that apparatus and methods provided herein are able to adhere to the different sizes and contours of a sealed can lid. Additionally, by way of example, the inventors have determined that apparatus and methods provided herein can permit the user to safely remove the top of the can with both ease and efficiency.

A can opener (1) for opening a can (2) comprises a rotating device (4), a body (5), a traction device (6), a removal device (8) comprising at least one engagement element (9), and a cutting device (7). The traction device (6) is configured to adapt at least a traction device cutting position (tc) and a traction device lifting position (tl). The traction device (6) in the traction device cutting position (tc) and the cutting device (7) are arranged so as to open a can (2). The traction device (6) in the traction device lifting position (tl) and the engagement element (9) in a removal device lifting position (rl) are arranged such as to engage a lid (3) of an opened can (2). An actuation of the removal device (8) t removes an engagement between the traction device (6) and the engagement element (9) with the lid (3).

The package opening device generally comprises a body portion, neck portion, and cutting member. In a preferred embodiment, the body portion comprises an elongated ovular configuration. The body portion comprises an upper surface and a lower surface. The neck portion is narrower than the body portion and extends from the proximal end of the body portion. The cutting member is fixed to the body portion and comprises an elongated configuration and is aligned along a central longitudinal axis of the body portion. The cutting member extends downward from the neck portion and body portion and comprises a cutting edge adapted to penetrate a portion of a package.

A device for opening and re-closing food-containing packages includes a pouring element with a circumferential flange for fastening to the package and a neck for pouring, as well as a cutting element, which is arranged inside the neck and has a plurality of teeth, which are arranged around the circumference and directed towards the package, and a screw cap, the cutting element cutting a pouring opening into the composite film material as a result of a rotational movement of the screw cap when the package is opened for the first time. The teeth of the cutting element have a steep gradient at the tip thereof, a shallower gradient at the flanks thereof and a steep gradient again at the bases thereof.

A lateral-cutting can opener assembly configured to pierce and make a continuous incision on a peripheral can wall or a peripheral rim wall. The lateral-cutting can opener assembly may include a first handle defining a distal portion and a proximal portion configured for grasping by a human hand, a second handle defining a central axis and including a gripping portion extending way from an anvil, a knife operably connected to the anvil and disposed at an inclination between 180 and 230 degrees relative to the central axis of the handle, a drive wheel configured to operably connect to the distal portion of the first handle and to operably connect the first handle to the second handle and including a shaft extending away from a drive wheel head. The first handle is configured to pivot relative to the second handle or the drive wheel.

A cutter is configured to be mounted to a push rod of a caulking gun. The push rod includes a pushing portion for pushing a container containing a caulking material and a rear end portion opposite to the pushing portion. The cutter includes: an assembling portion, configured to be mounted at the rear end portion of the push rod;

and a cutting portion, connected with the assembling portion and including a cutting member. A caulking gun including the cutter is further provided.
