Field of the Invention
The embodiments of the invention relate to a lid, and more particularly, to a lid with rotatable closure tab. Although embodiments of the invention are suitable for a wide scope of applications, it is particularly suitable for changeably sealing and opening a sipping port in a lid.
Discussion of the Related Art
In general, a lid for container snaps onto the brim of the container, preferably forming a seal between the lid and the brim that prevents liquid from seeping through. The lid typically has a sipping spout to facilitate drinking of a liquid from the container. A sipping spout is a raised portion of the lid having a sidewall upon which a user can place their lower lip and a top wall upon which a user can place their top lip over or near to sip liquid from the container. Such a sipping spout has an orifice in the top wall through which the liquid can slosh out or otherwise be spilt while the container is being transported or otherwise moved about. To prevent spillage from the orifice of the sipping spout, a user can either put their finger over the orifice of the sipping spout or cap the sipping spout with an other lid that covers the orifice of the sipping spout. The other lid is the same shape as the lid with the sipping spout having an orifice but the other lid does not have an orifice in its sipping spout shaped portion so as to block off or cover the orifice. The other lid of a two lid system may actually be comprised of more material than the lid with a sipping spout having an orifice.
Using an other lid requires two hands to open-up and/or close-off the orifice of the sipping spout as well as more than doubles the amount of materials needed to make a lid system in that two lids are used to make a closable sipping spout. Thus, a lid system that can be operated with one hand and which uses substantially less material than a two lid system is desirable. Although effective, the finger over the orifice of the sipping spout is messy and unsanitary.
Accordingly, embodiments of the invention are directed to a lid with rotatable closure tab that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
An object of embodiments of the invention is to provide a lid with rotatable closure tab in which the rotatable closure tab can be operated with one hand.
Another object of embodiments of the invention is to provide a lid with rotatable closure tab in which the rotatable closure tab is removably attached to the lid.
Another object of embodiments of the invention is to provide a lid with rotatable closure tab in which the rotatable closure tab is retained in position when closing-off the sipping port.
Another object of embodiments of the invention is to provide a lid with rotatable closure tab in which the rotatable closure tab is retained in position when not closing-off the sipping port.
Additional features and advantages of embodiments of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of embodiments of the invention. The objectives and other advantages of the embodiments of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of embodiments of the invention, as embodied and broadly described, a lid with rotatable closure tab, includes the lid including: a brim sealing channel at a periphery of the lid forming a circumference; an outer sipping sidewall positioned within the circumference of the brim sealing channel and extending above the brim sealing channel to provide a surface for a lower lip of a user to seal against; a sipping topwall adjacent to the outer sipping sidewall for providing a surface over which an upper lip of the user can be positioned; a sipping port in the sipping topwall; and a central recess within the circumference of the brim sealing channel and proximate to the sipping topwall, wherein the central recess has an overhang and a bottomwall; and the rotatable closure tab including: a central portion; a flanged-shaped structure at a first side of the central portion; a tab sidewall supported by the flanged-shaped structure; a tab topwall extending outwardly from the tab sidewall and away from the flanged-shaped structure; a sealing depression in the tab topwall for sealing the sipping port; and a retention rim extending radially from the central portion and positioned between the overhang and bottomwall of the central recess.
In another aspect, a rotatable closure tab for a lid includes: a central portion for insertion into a central recess of the lid; a flanged-shaped structure at a first side of the central portion opposite to the first side; a tab sidewall supported by the flanged-shaped structure; a tab topwall extending outwardly from the tab sidewall and away from the flanged-shaped structure; a sealing depression in the tab topwall for sealing a sipping port of the lid; and a retention rim extending radially from the central portion.
In yet another aspect, a lid for a rotatable closure tab includes: a brim sealing channel at a periphery of the lid forming a circumference; an outer sipping sidewall positioned within the circumference of the brim sealing channel and extending above the brim sealing channel to provide a surface for a lower lip of a user to seal against; a sipping topwall adjacent to the outer sipping sidewall for providing a surface over which an upper lip of the user can be positioned; a sipping port in the sipping topwall; an inner sipping sidewall opposite to the outer sipping sidewall and adjacent to the sipping topwall; a central recess within the circumference of the brim sealing channel and adjacent to the inner sipping sidewall, wherein the central recess has an overhang and a bottomwall.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of embodiments of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of embodiments of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of embodiments of the invention.
Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Like reference numerals in the drawings denote like elements.
The flanged-shaped structure 14 provides vertical support for a tab sidewall 15 that extends up and is positioned beyond the periphery of the two reinforcement channels 12a and 12b. Although a five faceted flanged-shaped structure 14 is shown in the disclosed exemplary embodiments, a flange-shaped structure can have two, three, four, six or more facets. Further, other geometric shapes can be implemented to provide vertical support for the tab sidewall 15.
A tab topwall 16 extending outwardly from the tab sidewall 15 and away from the flanged-shaped structure 14 and the two reinforcement channels 12a and 12b. A sealing depression 17 in the tab topwall 16 is provided for sealing a sipping port. Further, the sides of the sealing depression 17 increase the rigidity of the tab topwall 16.
A tab flap 18 extending from the tab topwall 16 and away from the flanged-shaped structure 14 and the two reinforcement channels 12a and 12b. A retention rim 19 extends outwardly beyond the nub 13 and the two reinforcement channels 12a and 12b toward the periphery of the rotatable closure tab 10.
The lid 20, as shown in
The separate rotatable closure tab can be manufactured on another manufacturing line different than the manufacturing line for the lid having a central recess. Manufacturing costs for making the rotatable closure tab are less than the costs of making a lid because the rotatable closure tab is smaller and uses less material. Further, a separate rotatable closure tab can be produced from a different gauge of material. That is, the rotatable closure tab is made of a thinner material than the lid to save even more costs. Compared to using one lid to seal another lid, the use of a rotatable closure tab to seal a lid is considerably cheaper.
The separate rotatable closure tab can be a different color than the lid or even a different material. For example, a black HIPS lid with a clear rotatable closure tab, in which the clear rotatable closure tab is a naturally clear material, such as clarified PP or APET. In another example, the rotatable closure tab is a black PP and the lid is a green APET.
The separate rotatable closure tab provides a modular capability for a lid with a central recess. The lid with a central recess can be used without the separate rotatable closure tab. The separate rotatable closure tab can be optionally added onto a lid with a central recess by a retailer's employee or a customer at a point of sale. Thus, and when, they wish to select it, and place it (snapping it into place) on the lid, thus creating the rotatable closure.
A rotatable closure according to embodiments of the invention is modular in that manufacturing of the rotatable closure may be produced on dedicated line separate from the production of the lid. Thus, the rotatable closure can be made separately and offered for sale as an adjunct to the lid, which can be purchased with or without the rotatable closure feature. The modularity serves to provide the end user with a sipping port option as, for example, the current lid user has in choosing whether to use a splash stick as an insert into sipping port. Because the rotatable closure is an add-on, the rotatable closure can be made from a different material than the lid. For example, the rotatable closure can be made of polypropelene, which settles and shrinks at a far less predictable rate than high impact polystyrene (HIPS), while the lid is made of HIPS. In addition to brand markings on the bottomwall of the central recess of the lid, specific product markings indicative of contents in a container can be on the central portion of the rotatable closure. In another alternative, product markings can be on the central recess of the lid while advertisement is on the central portion of the rotatable closure. Accordingly, embodiments of the invention provide for more flexibility in manufacturing, distribution, customer experience and marking of a lid with a closure.
It will be apparent to those skilled in the art that various modifications and variations can be made in the embodiments of the invention without departing from the spirit or scope of the invention. Thus, it is intended that embodiments of the invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
