Abstract
Abstract An earlobe piercing cartridge assembly for maintaining a piercing earring sterile during storage, handling and piercing is provided. The assembly includes a piercing earring including a piercing pin and an ornamental head which may have a large diameter compared to the diameter of the push rod, or may be made of a soft material, and from which the piercing pin projects. A cartridge uniquely configured to receive the piercing earring includes an elongated opening partially supporting the piercing pin, and a further opening proximate the ornamental head of the earring, and in longitudinal alignment with the elongated opening, the elongated opening having a smaller lateral dimension than the further opening. A shield is adapted to fit inside the cartridge between the ornamental head of the piercing earring and the further opening. The shield is also adapted to distribute the pressure across the ornamental head from a push rod which enters the further opening and facilitates smooth, low effort ear piercing with accurate axial alignment with the concentric or non-concentric ornament.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
An ear piercing assembly comprising in combination: a piercing earring including an ornamental head and a piercing pin projecting from the head; a cartridge adapted to receive the piercing earring and substantially envelope the piercing earring, the cartridge including an elongated opening partially supporting the piercing pin, and a further opening proximate the ornamental head of the earring, said further opening being in axial alignment with the elongated opening, the elongated opening having a smaller lateral dimension than the further opening; a shield means positioned within said cartridge between the ornamental head of the piercing earring and the further opening so that the pressure across the ornamental head from a push rod which enters the further opening is distributed by said shield means; and a housing means for receiving the cartridge and for positioning the cartridge openings in alignment with a push rod to prevent displacement of the cartridge when a push rod is displaced through the earring cartridge.
Claim 2
Dependent Claim
159 words
An ear piercing assembly comprising in combination: a piercing earring including an ornamental head and a piercing pin projecting from the head; a cartridge adapted to receive the piercing earring and substantially envelope the piercing earring, the cartridge including an elongated opening partially supporting the piercing pin, and a further opening proximate the ornamental head of the earring, said further opening being in axial alignment with the elongated opening, the elongated opening having a smaller lateral dimension than the further opening; a shield means positioned within said cartridge between the ornamental head of the piercing earring and the further opening so that the pressure across the ornamental head from a push rod which enters the further opening is distributed by said shield means; and a housing means for receiving the cartridge and for positioning the cartridge openings in alignment with a push rod to prevent displacement of the cartridge when a push rod is displaced through the earring cartridge.
Claim 3
Dependent Claim
117 words
The ear piercing assembly of claim 1, wherein the earring cartridge is constructed and arranged so that a portion of the cartridge defining the further opening is engaged by a push rod when the cartridge is displaced by a push rod from a rest position to an intermediate displaced position, the cartridge being adapted to be brought into contact with the smaller opening of the housing chamber means to prevent the cartridge from being ejected from the chamber means and to define the intermediate displaced position, so that the entry of a push rod through the further opening into contact with the shield means will result in the earring being indirectly forced through the elongated cartridge opening.
Claim 4
Dependent Claim
72 words
The ear piercing assembly of claim 2, wherein the earring cartridge is defined by two identical half-walls, the half-walls being joined by hinge means to permit the half-walls to be folded onto each other and substantially envelop the piercing earring, the half-walls defining hairline slits therebetween along the lengthwise extent of the cartridge to allow the elongated opening to expand and hinge in response to a forcing of the shield means therethrough.
Claim 5
Dependent Claim
22 words
The ear piercing assembly of claim 3, wherein the hinge means includes a hinge disposed at the end of the elongated opening.
Claim 6
Dependent Claim
57 words
The ear piercing assembly of claim 4, wherein the hinges disposed at the end of the elongated opening are dimensioned to permit the hinges to break in response to the shield means being forced into said elongated opening and thereby permit the half-walls to expand along the hairline slits and permit the earring to be forced therethrough.
Claim 7
Dependent Claim
51 words
The ear piercing assembly of claim 2, wherein the cartridge has a projection extending axially at the rear of the cartridge, and the housing means has a track adapted for receiving and guiding the projection when a push rod means is displaced from an initial position to an intermediate displaced position.
Claim 8
Dependent Claim
64 words
The ear piercing assembly of claim 2, and including a clutch adapted to be secured onto the piercing earring, and a clutch cartridge releasably secured to the earlobe support means, the clutch cartridge positioning the clutch in longitudinal alignment with the elongated cartridge opening, whereby the elongated opening guides the earring piercing pin into the clutch as the earring is forced from the cartridge.
Claim 9
Dependent Claim
23 words
The ear piercing assembly of claim 2, wherein the ornamental head is made of a material that is softer than the push rod.
Claim 10
Dependent Claim
53 words
The ear piercing assembly of claim 1, wherein the shield means includes a first piece and a second piece adapted to be positioned with respect to each other so that the ear piercing earring having a thin ornamental head is securely positioned in said cartridge and is aligned axially with the piercing pin.
Claim 11
Dependent Claim
58 words
The ear piercing assembly of claim 1, wherein the housing means includes at least one chamber having a first opening for inserting the cartridge, and a second opening of smaller diameter than said second opening to restrain said cartridge from being displaced out of said chamber when said cartridge is brought into proximity to said earlobe during piercing.
Claim 12
Dependent Claim
19 words
The ear piercing assembly of claim 1, wherein the ornamental head has a diameter no greater than 8 mm.
