Description

FIELD

The present disclosure relates to a multi-chamber tube container having a sealable cap with a plurality of orifices disposed therein.

BACKGROUND

This section provides background information related to the present disclosure, which is not necessarily prior art.

The use of plastic tube packaging is prevalent in the cosmetics, pharmaceutical, and food packaging industries for packaging thick liquids and pastes. Conventional plastic tube packaging consists of a single chamber tube package that dispenses a single substance when squeezed. In certain instances, it can be desirable to maintain two components of a product in separate chambers, mixing them only at the time of dispensation. Accordingly, multiple-chamber tubes have been developed. Dispensing product from and sealing multi-chamber tubes can be challenging.

SUMMARY

It is to be understood that this summary is not an extensive overview of the disclosure. This summary is exemplary and not restrictive, and it is intended to neither identify key or critical elements of the disclosure nor delineate the scope thereof. The sole purpose of this summary is to explain and exemplify certain concepts of the disclosure as an introduction to the following complete and extensive detailed description.

The present inventor has recognized that dispensing product from and, additionally or alternatively, sealing a multi-chamber tube container can be problematic. Devices, systems, and methods for dispensing product from and, additionally or alternatively, sealing a multi-chamber tube container are therefore desirable. Accordingly, the present teachings provide for multi-chamber tube container caps and associated systems and methods. In one aspect, the present disclosure can provide for a multi-chamber tube container comprising a tube cap. The tube cap can comprise a base plate that can be coupleable to the multi-chamber tube container. The base plate can comprise an opening disposed therein. The opening can be positionable in communication with a first tube head of a first tube or a second tube head of a second tube of the multi-chamber tube container. The tube cap can further comprise a lid that can be removably coupleable to the base plate. The lid can comprise a pintle extending from an inner surface of the lid and, additionally or alternatively, a gasket disposed on the inner surface of the lid. When the lid and the base plate are coupled, the pintle can extend into and seal a first orifice disposed in the first tube head and, additionally or alternatively, the gasket can be urged into sealing contact with a second orifice disposed in the second tube head of the second tube of the multi-chamber tube container. The first orifice can be located in a central portion of the base plate. Additionally or alternatively, the second orifice can comprise a plurality of second orifices.

Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings.

The present teachings provide for multi-chamber tube container caps and associated systems and methods. Such tube caps and associated systems and methods can provide for dispensing of product from and, additionally or alternatively, sealing of a multi-chamber tube container. Such tube caps and multi-chamber tube containers can enable separate substances to be dispensed simultaneously from separate containers and, additionally or alternatively, mixed at the point of use.

With initial reference to FIGS. 1-8, a system 100 comprises a multi-chamber tube container 102 comprising a tube cap 104. The tube cap 104 can comprise a base plate 106 that can be coupleable to the multi-chamber tube container 102 and a lid 120 that can be removably coupleable to the base plate 106.

In one aspect, the base plate 106 can comprise an opening 107 for receiving a first tube head 114 of a first tube 112 and a second tube head 118 of a second tube 116 of the multi-chamber tube container. A first orifice 108 can be disposed in the first tube head 114 and a second orifice 110 can be disposed in a second tube head 118. A top portion of either or both of the first tube head 114 and the second tube head 116 can be circumscribed by a transition surface 126 extending upward from the base plate 106 around the opening 107. The transition surface 126 can be either or both beveled and chamfered.

In another aspect, the first orifice 108 can be located in a central portion of the base plate 106 and each of the plurality of second orifices 110 can be spaced circumferentially about the first orifice 108 of the multi-chamber tube container 102. Each of the first tube head 114 and the second tube head 118 can optionally be circumscribed by a transition surface 126 when the tube cap is engaged with the tube.

In another aspect, the lid 120 can comprise a pintle 122 extending from an inner surface of the lid 120 and, additionally or alternatively, a gasket 124 disposed on the inner surface of the lid 120. The lid can optionally further include a gasket skirt 128 extending from the inner surface of the lid 120. The gasket skirt 128 can bound the outer circumferential edge of the gasket 124 and can constrain the gasket 124 from lateral expansion upon compression. When the lid 120 and the base plate 106 are coupled, the pintle 122 can extend into and seal the first orifice 108 and, additionally or alternatively, the gasket 124 can be urged into sealing contact with the second orifice 110 (or plurality of second orifices 110). At least a portion of the pintle 122 can be tapered from a first point to a second point spaced farther from the lid from the first point.

In one aspect, the lid 120 can be hingedly coupled to the base plate 106. The pintle 122 and first orifice 108 can cooperate to bias the lid 120 and base plate 106 in the closed position upon a user applying a sufficient closing force to couple the lid 120 and base plate 106 via engagement of the pintle 122 in the first orifice 108. Conversely, upon a user applying an opposite and sufficient opening force, the pintle 122 can be disengaged from the first orifice 108 to bias the lid 120 and the base plate 106 to an open position.

In an optional aspect, the lid 120 and the base plate 106 comprise further latching features to augment pintle/first orifice engagement mechanism described above. The base plate 106 can comprise a thumb plate 130 disposed on a portion of a base plate skirt 132 extending downward from the circumferential edge of the base plate 106. The lid 120 can comprise a lid skirt 134 extending from the inner surface of the lid 120. The lid skirt 134 can comprise a latch plate 136 that is complementary to the thumb plate 130. The thumb plate 130 can have at least one protrusion disposed thereon that cooperates with the latch plate 136 to further bias the lid 120 and the base plate 106 in the closed position upon a user applying sufficient closing force to engage the latching feature. Conversely, upon a user applying an opposite and sufficient opening force, the latch plate 136 can disengage from the thumb plate 130 to bias the lid 120 and the base plate 106 into an open position.

In another embodiment illustrated in FIGS. 9A-9B, a system 200 can comprise a multiple-chamber tube container 202 having a tube cap 204 that can be threadably coupleable to the base plate 206. In an additional or alternative aspect, the tube cap 204 can further comprise a gasket 234 extending from a bottom surface thereof. The gasket 234 can fixedly engage at least one of the first tube head 214 and the second tube head 218 of the multi-chamber tube 202 when the tube cap 204 is urged into mating contact with the multi-chamber tube container 202.

In another embodiment illustrated in FIG. 10, a system 300 can comprise a multiple-chamber tube container 302 comprising a tube cap 304. The tube cap 304 can comprise a base plate 306 that can be coupleable to the multi-chamber tube container 302. The tube cap 304 can comprise an opening 307 disposed therein for receiving at least one tube head of the multi-chamber tube. The multi-chamber tube has a tube head with at least one orifice 310 disposed therein corresponding to each tube thereof. The tube cap 304 can further comprise a lid 320 that can be removably coupleable to the base plate 306. The lid 320 can comprise a gasket 324 disposed on an inner surface of the lid 320 that can optionally be surrounded by gasket skirt 328 substantially as described above with respect to FIGS. 1-8. When the lid 320 and the base plate 306 are coupled, the gasket 324 can be urged into sealing contact with each of the plurality of orifices 310.
