This application claims priority/benefit of provisional application U.S. 60/807,261, filed Jul. 13, 2006
The present invention relates to cosmetic product packages that include shock absorbing means. In particular, the present invention is directed to compact cases with solid or semi-solid cosmetic products pressed or caste in a support pan. More particularly, the invention is directed to the means for isolating the product containing pan from external shock.
Compacts for solid or semi-solid cosmetic products generally comprise a base and a corresponding cover. The base has at least one cavity dimensioned to receive the cosmetic. A shallow plastic or metal pan containing the solid or semi-solid cosmetic product is secured in the cavity. The solid or semi-solid cosmetic product may be, for example, a pressed or caste powder, a semi-solid paste, or a cake-like consistency. The category of cosmetic may be, for example, a powder (e.g., blush), a skin foundation, an eye shadow, a lip cosmetic, etc.
During shipping or during the normal lifespan of the product, the compact may be subjected shocks or impacts, for example, when the compact is accidentally dropped. Some formulations of solid and semi-solid cosmetics provided in shallow trays are susceptible to cracking and/or crumbling when the cosmetic case is subjected to external shock, vibration or impact. This is particularly true for higher quality pressed powders manufactured with less compression to provide a softer ‘feel’ to the user and better product payoff onto the fingers or an applicator. Clearly, a cracked or crumbled cosmetic product is undesirable as it presents a negative impression to a consumer. Furthermore, the cracked or crumbled cosmetic may negatively impact the performance of the product. For example, cracked or crumbled product may load unevenly onto an applicator (e.g., a brush or a pad). This in turn may lead to an undesirable and unattractive distribution of product on the user's skin.
Some attempts have been made to rectify the problem. For example, Japanese publication No. 2006061189 discloses a cosmetic compact with a cosmetic tray detachably fixed in a recess by a collar such that the bottom wall of the tray and the bottom wall of the recess are separated by an air layer.
Japanese publication No. 2005304850 discloses a cosmetics container for storing, e.g., foundation and eye shadow. The container includes inner plates that form cosmetic storage chambers. The plates are selectively mounted at the bottom of the container by way of cushion members.
Japanese publication number 9-191928 discloses a shock absorbing and thin walled inner plate formed from a thin synthetic sheet. A second inner plate (presumably non-shock absorbing) is laid in the shock absorbing inner plate. The shock absorbing inner plate includes projections for coming in contact with the inner surface of the housing bottom.
U.S. Pat. No. 5,713,471 discloses a packaging unit including a supporting element with a cavity for receiving a pan containing cosmetic. The pan is secured in the cavity by elastic holding means (e.g., an o-ring). In addition, compressible means in the form of flexible foam or flexible spikes may be provided beneath the pan to compensate for play and/or protect against vibration.
Japanese publication No. 2002-177044 discloses a container body with clearance for receiving an inner tray for cosmetics. Elastic arms provided in opposite sides of the clearance have protrusions to detachably engage recesses in the sides of the inner tray. The elastic arms are said to provide properties against a shock to the inner tray.
U.S. Pat. No. 1,552,173 discloses a powder box in which resilient means are provided beneath a false bottom to press powder on the false bottom up through a perforated dispensing partition.
French patent number 2691339 discloses a compact with a pan supported on springs provided to eject the pan from the base to effect a change of pans.
U.S. Pat. No. 1,194,187 discloses a rouge box with a rouge holding pad yieldably held at the top of the box by a supporting spring such that when the box is opened the rouge is readily accessible at all times. The rouge pad is snuggly received in the box. Accordingly, there does not appear to be a gap of sufficient dimension to provide for lateral movement of the pad in the box.
U.S. Pat. No. 2,054,004 discloses a vanity case for loose powder with springs that push a powder receptacle (a pan) upwardly such that an upper edge of the receptacle maintains contact with the underside of a cover when the case is closed, thus preventing leakage or spilling of the powder.
Japanese publication number 09-299138 discloses an inner tray for a cosmetic with protrusions formed on the outside. The protrusions match a groove on the inside of the compact base. The inner tray with the protrusions is said to give good shock resistance.
Japanese publication number 06-189821 discloses a cosmetic compact with a rubber gasket in an annular form between a lower lid and the cosmetic tray such that a space is formed between the lower lid and the cosmetic tray.
None of the forgoing references disclose a cosmetic compact for pressed powder with a pan received in a clearance in the base of the compact such that a gap is defined between the pan and the base, and wherein the pan is suspended by arcuate members across the gap and positioned along transverse axes. Accordingly, there is a need for a cost effective, mass produce-able cosmetic case having shock absorber means that effectively prevents pressed powder cosmetics from fracturing.
The present invention is directed to means for dampening shocks, impacts and vibration transmitted from the base of a cosmetic compact to a pan supported within the compact. The pan is adapted to contain solid or semi-solid cosmetic, e.g., a pressed powder, which is susceptible to damage in the form of cracking or crumbling, or in the worst case, release from the pan. The shock absorbing means minimizes or eliminates damage to the cosmetic product caused by external shock, impact or vibration. The pan is positioned in a clearance in the base large enough to provide for an air gap about the pan. The shock absorbing means comprises at least two arcuate, resilient portions extending across the gap to connect the pan to the base. One arcuate portion is directed along a first axis, and the second arcuate member is directed along a second axis transverse to the first. The arched portions are sufficiently resilient to allow the pan to move relative to the base to a degree that prevents shock, impact or vibration from being transmitted from the base to the pan.
In a first embodiment, the arcuate portions are part of a continuous arched web that connects the pan to the base of the compact. Alternatively, the arched web may include discontinuities, such as, for example, cuts or openings, adapted to provide more reactive and resilient shock absorbing characteristics.
In a second embodiment, the shock absorbing device comprises a space-saving planar configuration, i.e., a plate within a plate, inserted between the pan and the base of the compact. An outer plate has a central clearance, and an inner plate is suspended in the central clearance such that a gap is defined between an outer edge of the inner plate and an inner edge of the outer plate. The inner plate is suspended in the clearance by at least two arcuate members. The outer plate is adapted to connect to one of the base or the pan, and the inner plate is adapted to connect to the other of the base or the pan.
Thus, two embodiments of a cost effective, mass produce-able shock absorbing means are provided for a cosmetic compact case. Either embodiment can readily be adapted for installation in existing compact case designs. The shock absorbing means effectively prevent pressed powder cosmetics from fracturing.
Referring now to
A shock absorbing member 30 is provided to connect the base to the pan. In the embodiment illustrated in
While four arcuate portions are illustrated by the broken lines 31, it will be understood that the number of arcuate portions may vary from a minimum of two to any suitable number necessary to prevent damage to the contents of the pan. Preferably, at least two arcuate portions are provided, one directed along first axis 34 and another directed along second axis 38 transverse to the first axis. More preferably, as illustrated, a pair of arcuate portions, 32 and 40 is provided along axis 34, and a pair of arcuate portions 36 and 42 is provided along axis 38, each one of a pair on opposite sides of the pan 6.
The arcuate portions 32, 36, 40, 42 may form part of a continuous arcuate web 44, as illustrated in
In the first embodiment, preferably, the each arcuate portion 32, 36, 40, 42 comprises at least one upwardly directed arch 45 (see
As illustrated in the cross-sectional view in
The shock absorbing member 30 may be made from any suitable plastic or elastomer material, such as, for example, rubber, styrene, acetal, polyethylene, polypropylene. The member may be made by any suitable method, such as, for example, injection molding, die-cutting, etc.
In another embodiment, the shock absorbing member 30 comprises a planar shock absorbing device 130 (
First, second, third and fourth arcuate portions, 132, 136, 140, 142, respectively, each horizontally oriented with an arch within the plane occupied by the inner plate 137 and outer plate 133, extend across the gap to connect the outer plate 133 to the inner plate 137. The first and third arcuate portions, 132, 140, are positioned along a first axis 134 on opposite sides of the inner plate. The second and fourth arcuate portions, 136, 142, are positioned on opposite sides of the inner plate along a second axis 138 that is transverse to the first axis 134. Each of the arcuate portions, 132, 136, 140, 142, is sufficiently resilient to permit movement of the inner plate 137 relative to the outer plate 133 thereby reducing transmission of shock or vibration from the base 14 to the pan 6. The arcuate portions work individually or in concert to dampen and minimize the transmission of shock and/or vibration from the base to the pan, thus, substantially eliminating damage to the cosmetic product P in the form of cracking or crumbling.
It will be understood that the number of arcuate portions provided in the planar shock absorbing device 130 may vary from a minimum of two to any suitable number necessary to prevent damage to the contents of a pan attached to the device. Preferably, at least two arcuate portions are provided, one directed along a first axis 134 and another directed along second axis 138 transverse to the first axis. More preferably, pairs of arcuate portions are provided along each axis, one on each side of the inner plate 137. However, any reasonable number of arcuate portions may be provided.
The outer plate 133 may further comprise an upwardly directed sidewall 153 extending upwardly from a perimeter 151 of the outer plate (
A channel 160 may be provided in the outer plate 133 or the inner plate 137, or both, to accommodate each arcuate portion 132, 136, 140, 142. The channel 160 permits the arcuate portions to be relatively long and the inner and outer plates to have relatively larger surface areas for attachment to the compact base and/or pan bottom.
The arcuate portions 132, 136, 140, 142 may have varying configurations. For example, the arcuate portions may comprise a curved arch 181 (
The plate-like shock absorbing device may be formed with all its parts as a unitary integral piece. The outer plate, the inner plate, and the arcuate portions can all be molded as one piece or cut from a single pieced of base stock by, for example, injection molding or die-cutting, respectively. The unitary piece may comprise a part of the compact base, e.g., the bottom wall of an insert in the base (see
In the above embodiments, the arcuate portions may also be adapted to provide progressive dampening by varying a thickness along a length of the respective arcuate portion as illustrated by arcuate portion 187 in
Either of the above embodiments may be made from any suitable plastic, elastomer (natural or synthetic) or metal by conventional methods, such as, for example, molding or cutting. The material should be selected to provide appropriate levels of resilience to keep the product from cracking. Examples of suitable materials include acetal, polypropylene, polyethylene, styrene and elastomer. If the shock absorbing device 130 is made from a plastic material, the thickness of the plates and the arcuate members is preferably 0.5 to 2.5 mm.
It is understood that various modifications and changes in the specific form and construction of the various parts can be made without departing from the scope of the following claims.
