Description

SUBSTANTIVELY HERMETICALLY SEALING CONTAINER

TECHNICAL FIELD

The present invention relates to containers for cosmetic, hygiene, and other consumer products in powdered or liquid form, and particularly hermetically sealing containers. The present invention also relates to containers for condiments, food, and drinks.

BACKGROUND

The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions.

Many commercial airline passengers need or desire to carry cosmetic products or medications on board and use these formulations during the course of a flight. However, the security processes at airports have become much more stringent, particularly since the terrorist attack in New York on September 11, 2001. Passengers are often only permitted to carry a limited number of small containers in which liquid material is stored. Also, security officers are typically required to direct passengers to open these containers to inspect the enclosed material and any other content.

Conventional containers provide some solutions to control the release of the content material. U.S. Patent Number 8,132,578 discloses a removable sifter disk inserted in a cosmetic package to control the release of the powdered content material. U.S. Patent Number 8,360,259 discloses automatic opening-and-closing discharging structure in a jar. However, the prior art fails to optimally provide easily inspectable devices of preconfigured internal volume. There is a therefore a long-felt need to develop sealing containers that contain specific volumes of material and can easily be opened and resealed during security inspections.

SUMMARY AND OBJECTS OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

Described embodiments provide improved sealing containers. It is an object of the present invention to provide sealing containers that may be opened and resealed and define a predetermined maximum volume of material when in a sealed state.

In one embodiment, such containers include a base with an internal ledge extending from the internal surface of the base wall towards the central axis of the base, a cover with a pressure ledge on its internal surface, and a sealing plate residing upon the perimeter lip of a screen adapted to reside on the base wall internal ledge and sealing the content material when the cover and the base are coupled. A sealing of the content material is removably formed between by forcing the cover pressure ledge against the substantively impermeable sealing plate and toward a bottom of the base whereby the sealing plate is compressed against the screen perimeter lip. The sealing plate and the internal cavity of the base define a maximum volume of material that may be contained when the invented container is on a closed state.

In another alternate preferred embodiment, a second screen is detachable from the base. Optional features may be included in the second screen design to allow ease of manual handling of the screen such as insertion and removal of the screen relative to the base.

Referring generally to the Figures and particularly to Figure 1A and Figure IB, Figure 1A and Figure IB illustrate a substantively hermetically sealing first container 100 according to a first embodiment. As shown in Figure 1A and Figure IB, the first container 100 includes three detachable components, namely a first base 102 having a first screen 104, a first sealing plate 106, and a first cover 108. The first container 100 may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity.

As shown in Figure IB, extending from an internal surface of the first base 102, the first base 102 defines a first reservoir 110, wherein a content material (not shown) of the first container 100 is stored. Fluids and sufficiently small particulates may enter and exit the first reservoir 110 through one or more first screen apertures 111 formed within and extending through the first screen 104.

In the first embodiment, the first base 102 has a first bottom 112 at a first end, and a first wall 114 extends from the first bottom 112. In the first container 100, the first wall 114 extends from the first bottom 112 at least partly along a first central axis 116. In the first container 100, near a second end of the first base 102 that is opposite to its first end, the first outer surface of the first wall 114 includes an attachment first section 118. The attachment section first 118 is threaded. In first embodiment, attachment first section 118 includes a first screen 104.

As shown in Figure 1A and Figure IB, the first screen 104 is preferably porous, permitting the content material housed within the first reservoir 110 to pass through the first screen 104. As further shown in Figure 1A and Figure IB, the first sealing plate 106 is adapted to sit upon the first screen 104 and be pressed against a first perimeter lip 120 of the first base 102 by compressive force delivered from the first cover 108 and to substantively inhibit exit of the content material from the first reservoir 110. The first sealing plate 106 thereby forms a substantive hermetic seal with the first base 102 that substantively or completely inhibits exit of the content material from within the first container 100. The first sealing plate 106 is adapted to rest upon the first perimeter lip 120 while receiving

compressive force from the first cover 108. As shown in Figure 1A and Figure IB, the first sealing plate 106 also includes a first handle 122 that may be manipulated by a user to separate the first sealing plate 106 from the first screen 104 or the first base 102.

As still further shown in Figure 1A and Figure IB, the first cover 108 is adapted to direct compressive force against the first sealing plate 106 and toward the first base 102 via a first cover pressuring feature 124, and to thereby substantively seal the content material within in the reservoir 110. The cover pressuring feature 124 is a portion of the first cover 108. The first cover 108 further includes a first cover attachment feature 126 that is adapted to detachably couple with the first base attachment section 118. In first embodiment, as shown in Figure 1A and IB, the first cover attachment feature 126 is tapped and is adapted to engage with the threaded attachment first section 118 of the base 102 and thereby provide compressive force from the cover pressuring feature 124 to the first screen 104 and toward the first perimeter lip 120 of the first base 102. The first cover 108 is shaped in combination with the first base 102 to fully enclose the first sealing plate 106 when the first cover 108 and the first base 102 are coupled.

It is understood that the first cover 108 is sized and shaped such that, in a first preferred embodiment of the method of the invention, a lower lip 128 of the first cover 108 is not positioned sufficiently proximate to a first side ledge 130 of the first wall of the first base 102 to enable transfer of force from the first cover 108 and to the first side ledge 130 when force is being transferred from the first cover pressuring feature 124 of the first cover 108 to the first sealing plate 106. The first container 100 is thus shaped such that compressive force may be transferred from the first cover 108 to the first sealing plate 106 without substantive limitation by interference with the first side ledge 130 of the first base 102.

Referring now generally to the Figures and particularly to Figures 2A, 2B and 2C, Figures 2A, 2B and 2C illustrate a substantively hermetically sealing second container 200 structured according to a second embodiment. As shown in Figures 2A, 2B and 2C, the second container 200 includes a second base 202 having a second screen 204, a second sealing plate 206, and a second cover 208. The second container 200 may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. As shown in Figure 2B, extending from the internal surface of the second base 202, the second base 202 defines a second reservoir 210, wherein the content material is stored. In the second container 200, the second base 202 has a second bottom 212 at a first end, and a second wall 214 extends from the second bottom 212. A second wall 214 of the second base 202 extends from the second bottom 212 at least partly along a second central axis 216. Near a second end of the second base 202 that is opposite to its first end, the outer surface of the second wall 214 is threaded. The second wall 214 is connected with a second screen 204 of the second base 202. Fluids and sufficiently small particulates may enter and exit the second reservoir 210 through one or more second screen apertures 211 formed within and extending through the second screen 204.

As shown in Figures 2A, 2B and 2C, the second screen 204 is porous, permitting the content material stored within the second reservoir 210 to pass through the second screen and out of the second base 202.

As shown in Figures 2A, 2B and 2C, the second sealing plate 206 is adapted to sit upon the second screen 204 and to substantively inhibit exit of the content material from the second reservoir 210. The second sealing plate 206 forms a substantively hermetic sealing that substantively completely inhibits exit of the content material from within the second container 200. The second sealing plate 206 is adapted to rest upon the second perimeter lip 218. As shown in Figure 2A, 2B and 2C, the second sealing plate 206 also includes a second handle 220 that may be manipulated by a user to separate the second sealing plate 206 from the second screen 204, i.e., from the second base 202. The second sealing plate 206 includes a second holding plate 222 and a second applicator pad 224, The second applicator pad 224 is adapted to absorb and/or adhere content material from within the second base 202.

As shown in Figures 2A, 2B and 2C, the second cover 208 is adapted to direct compressive force (a.) against the second sealing plate 206 and (b.) toward the second base

202 via a second cover pressuring features 226, and thereby to substantively seal the content material within in the second reservoir 210. The cover pressuring features 206 are each portions of the second cover 208. The second cover 208 includes a second cover attachment feature 228 that is adapted to detachably couple with the second base 202. The second cover attachment feature 228 is tapped and a base attachment feature 230 is threaded, wherein the second cover attachment feature 228 and the second base attachment feature 230 are adapted to engage to form a coupling of the second base 202 and the second cover 206. The second cover 208 may thus be manually screwed down by a user about the second base attachment feature 230 and toward the second bottom 212 of the second base 202 whereby drive compressive force is directed by the second cover 208 and against the second sealing plate 206 and toward the second perimeter lip 212 of the second base 202.

The second cover 208 is shaped in combination with the second base 202 to fully enclose the second sealing plate 206 when the second cover 208 and the second base 202 are coupled.

Referring generally to the Figures and particularly to Figure 3A, Figure 3B and Figure 3C, Figures 3A, 3B and 3C illustrate a substantively hermetically sealing third container 300 according to third embodiment of the present invention. As shown in Figure 3A, 3B and 3C, the third container 300 includes a third base 302 with a third screen 304, a third sealing plate 306, and a third cover 308. The third container 300 may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity.

As shown in Figures 3A, 3B and 3C, extending from an internal surface of the third base 302 defines a third reservoir 310, wherein the content material of the third container 300 is stored. Fluids and sufficiently small particulates may pass through the third screen 304, and thereby enter and exit the third reservoir 310, through one or more third screen apertures 311 formed within and extending through the third screen 304.

The third base 302 has a third bottom 312 at a first end, and a third wall 314

extending from the third bottom 312. The third wall 314 extends from the third bottom 312 at least partly along a third central axis 316. Near a second end of the third base 302 that is opposite to its first end of the third base 302, an outer surface of the third wall 314 includes a third attachment section 318. The third attachment section 318 is threaded.

As shown in Figures 3A, 3B and 3C, the third screen 304 is porous and permitting the content material in the third reservoir 310 to pass through the third screen 304 and from within the third base 302.

As shown in Figures 3A, 3B and 3C, the third sealing plate 306 is adapted to be pressed against the third screen 304 by compressive force delivered from the third cover 308 and to substantively inhibit exit of the content material from within the third reservoir 310. The third sealing plate 306 is adapted to form a hermetic sealing that substantively or completely inhibits exit of the content material from within the third container 300.

It is understood that the third cover 308 is sized and shaped such that, in a third preferred embodiment of the method of the invention, a third lower lip 320 of the third wall of the third cover 308 is not positioned sufficiently proximate to a third side ledge 322 of the third base 302 to transfer force from the third cover 308 and to the third side ledge 322 when force is being transferred from the third cover 308 to the third sealing plate 306. The third container 300 is thus shaped such that compressive force may be transferred from the third cover 308 to the third sealing plate 306 without substantive limitation due to interference between the third side ledge 322 of the third base 302 and the third cover 308.

The third sealing plate 306 is adapted to rest upon the third screen 304. In third embodiment, as shown in Figures 3A, 3B and 3C, the third sealing plate 306 also includes a third handle 324 with which a user may manipulate to separate the third sealing plate 306 from the third screen 304 and the third base 302.

As shown in Figures 3A, 3B and 3C, the third cover 308 is adapted to direct compressive force against the third sealing plate 306 and toward the third base 302 from a cover pressuring feature 326, and to thereby substantively seal the content material within the third reservoir 310. The third cover pressuring feature 326 is a portion of the third cover 308. The third cover 308 further includes a third cover tapped attachment feature 328 that is adapted to detachably couple with the threaded third attachment section 318 of the third base 302. In the third container 300, as shown in Figures 3A, 3B and 3C, the third cover attachment feature 328 is tapped. The third cover 308 is shaped in combination with the third base 302 to fully enclose and press against the third sealing plate 306 when the third cover 308 and the third base 302 are fully or substantively coupled by engagement and coupling of the third cover tapped attachment feature 328 of the third cover 308 with the threaded third attachment section 318 of the third base 302.

Referring now generally to the Figures and particularly to Figures 4A and 4B,

Figure 4A and Figure 4B illustrate a substantively hermetically sealing container according to fourth embodiment. As shown in Figures 4A and Figure 4B, a fourth container 400 includes a fourth base 402, a fourth screen 404, a fourth sealing plate 406, and a fourth cover 408. The fourth container 400 may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. As shown in Figure 4B, extending from the internal surface of the fourth base 402, the fourth base 402 defines a fourth reservoir 410, wherein the content material of the fourth container 400 is stored. Fluids and sufficiently small particulates may pass through the fourth screen 404, and thereby enter and exit the fourth reservoir 410, through one or more fourth screen apertures 411 formed within and extending through the fourth screen 404.

The fourth base 402 has a fourth bottom 412 at a first end, and a fourth wall 414 extends from the fourth bottom 412. A fourth wall 414 of the fourth base 402 extends from the fourth bottom 412 at least partly along a fourth central axis 416. Near a second end of the fourth base 402 that is opposite to its first end, the outer surface of the fourth wall 414 includes a fourth attachment section 418. The fourth attachment section 418 is threaded.

As shown in Figures 4A and Figure 4B, the removable fourth screen 404 is porous, permitting the content material in the fourth reservoir 410 to pass through and to exit the fourth base 402. As shown in Figure 4B, the fourth screen 404 includes a fourth sealing ledge 420 that is adapted to provide a snap fit friction fit for securely holding the fourth screen 404 within the fourth base 402.

The fourth screen 404 is detachable from and sized to fit within the fourth base 402. The fourth screen 404 includes a fourth perimeter lip 422. An additional fourth internal screen supporting feature 424 of the fourth base 402 extends from the internal surface of the fourth base wall 414 towards the fourth central axis 416, and the fourth perimeter lip 422 of the fourth screen 404 is correspondingly shaped to be capable of resting on top of the fourth internal screen supporting feature 424. The fourth internal screen supporting feature 424 is preferably a ring-shaped base internal ledge that extends towards the fourth central axis 416.

It is understood that the fourth cover 408 is sized and shaped such that, in a fourth preferred embodiment of the method of the invention, a fourth lower lip 426 of the fourth cover 408 is not positioned sufficiently proximate to a fourth side ledge 428 of the fourth base 402 to transfer force from the fourth cover 408 and to the fourth side ledge 428 when force is being transferred from the fourth cover 408 to the fourth sealing plate 406. The fourth container 400 is thus shaped such that compressive force may be transferred from the fourth cover 408 to the fourth sealing plate 406 without substantive limitation by interference between the fourth side ledge 428 of the fourth base 402 and the fourth cover 408.

As shown in Figure 4A and Figure 4B, the fourth sealing plate 406 is adapted to sit upon the fourth screen 404 and to substantively inhibit exit of content material from within the fourth reservoir 410. A fourth seal is thereby generated between an external perimeter area of the fourth sealing plate 406 and an external perimeter area of the fourth screen 404 and the fourth seal is supported by a compressive force transferred from the fourth cover 408 to the fourth sealing plate 406. The compressive force received by the fourth sealing plate 406 from the fourth cover 408 is substantively transferred through the fourth screen 404 and to the fourth base 402. The fourth sealing plate 406 and the fourth screen 404 preferably present a substantively equivalent external diameter along a plane normal to the fourth central axis 416.

The fourth sealing plate 406 forms a substantively hermetic sealing that completely or partially inhibits exit of the content material from the fourth container 400. The fourth sealing plate 406 is adapted to rest upon the fourth perimeter lip 422 of the fourth base 402.

As shown in Figure 4A and Figure 4B, the fourth sealing plate 406 also includes a fourth handle 430 that enables a user to manipulate and separate the fourth sealing plate 406 from the fourth screen 404 and the fourth base 402.

As shown in Figure 4A and Figure 4B, the fourth cover 408 is adapted to direct force against the fourth sealing plate 406 and toward the fourth base 402 via a fourth cover pressuring feature 432, and thereby to substantively seal the content material in the fourth reservoir 410. The fourth cover pressuring feature 432 is a portion of the fourth cover 408. The fourth cover 408 further includes a fourth cover attachment feature 434 adapted to detachably couple with the fourth base attachment section 418. As shown in Figure 4A and Figure 4B, the fourth cover attachment feature 434 may be tapped. The fourth cover 408 is shaped in combination with the fourth base 402 to fully enclose the fourth sealing plate 406 when the fourth cover 408 and the fourth base 402 are coupled. The fourth cover 408 is further shaped to enclose the fourth handle 430 when the fourth cover 408 and the fourth base 402 are coupled.

Referring now generally to the Figures and particularly to Figure 5A and Figure 5B, Figure 5A and Figure 5B illustrate a substantively hermetically sealing container 500 according to a fifth embodiment. As shown in Figure 5A and Figure 5B, the fifth container 500 includes a fifth base 502, a fifth screen 504, a fifth sealing plate 506, and a fifth cover 508. The fifth container 500 may be or comprise metal, plastic, wood or wood composite, ceramic or other suitable material known in the art in combination or in singularity. As shown in Figure 5B, extending from the fifth internal surface of the fifth base 502, the fifth base 502 defines a fifth reservoir 510, wherein content material of the fifth container 500 is stored. Fluids and sufficiently small particulates may pass through the fifth screen 504, and thereby enter and exit the fifth reservoir 510, through one or more fifth screen apertures 511 formed within and extending through the fifth screen 504.

The fifth base 502 has a fifth bottom 512 at a first end, and a fifth wall 514 that extends from the fifth bottom 512. The fifth wall 514 extends from the fifth bottom 512 at least partly along a fifth central axis 516. Near a second end of the fifth base 502 that is opposite to its first end, an outer surface of the fifth wall 514 includes a threaded fifth attachment section 518.

As shown in Figure 5A and Figure 5B, the fifth screen 504 is porous, permitting the content material in the fifth reservoir 510 to pass through and from within the fifth base 502.

The fifth screen 504 is sized to fit within the fifth base 502, and includes a fifth perimeter lip 520. A fifth internal screen supporting feature 522 of the fifth base 502 extends from the internal surface of the fifth base wall 514 towards the fifth central axis 516. The fifth perimeter lip 520 is correspondingly shaped to be capable of resting on top of the fifth internal screen supporting feature 522 as part of the fifth container 500. The fifth internal screen supporting feature 522 is preferably a ring-shaped base internal ledge extending towards the fifth central axis 516.

As shown in Figure 5A and Figure 5B, the fifth sealing plate 506 is adapted to sit upon the fifth screen 504 and to substantively inhibit exit of the content material from within the fifth reservoir 510. The fifth sealing plate 506 is detachably pressed by the fifth cover 508 against the fifth base 502 to form a at least partially hermetic sealing that at least substantively inhibits exit of the content material from the fifth container 500. The fifth sealing plate 506 is adapted to rest upon the fifth perimeter lip 520.

It is understood that the fifth cover 508 is sized and shaped such that, in a fifth preferred embodiment of the method of the invention, a fifth lower lip 524 of the fifth cover 508 is not positioned sufficiently proximate to a fifth side ledge 526 of the fifth base 502 to transfer force from the fifth cover 508 and to the fifth side ledge 526 when force is being transferred from the fifth cover 508 to the fifth sealing plate 506. The fifth container 500 is thus shaped such that compressive force may be transferred from the fifth cover 508 to the fifth sealing plate 506 without substantive limitation by interference between the fifth side ledge 526 of the fifth base 502 and the fifth cover 508.

As shown in Figure 5A and Figure 5B, the fifth sealing plate 506 also includes a fifth handle 528 that enables a user to manually separate the fifth sealing plate 506 from the fifth screen 504 and the fifth base 502.

As shown in Figure 5A and Figure 5B, the fifth cover 508 is adapted to direct compressive force against the fifth sealing plate 506 and toward the fifth base 502 via a fifth cover pressuring feature 530, and to thereby substantively seal the content material within the fifth reservoir 510. The fifth cover pressuring feature 530 is a portion of the fifth cover 508. The fifth cover 508 includes a fifth cover tapped attachment feature 532 that is adapted to detachably engage and couple with the fifth base threaded attachment section 518. The fifth cover 508 is shaped in combination with the fifth base 502 to fully enclose the fifth sealing plate 506 when the fifth cover 508 and the fifth base 502 are coupled. The fifth cover 508 is further shaped to enclose the fifth handle 528 when the fifth cover 508 and the fifth base 502 are coupled.
