Description

FIELD OF THE INVENTION

The present invention relates to drinking vessels, and more particularly, to modular, disassemblable or knock-down drinking vessels.

BACKGROUND OF THE INVENTION

Drinking vessels are subject to many different demands. For most purposes, it is desirable that a drinking vessel be inexpensive, readily cleaned, have a closure, and optionally have an integral spout or mouthpiece facilitating preventing spillage while drinking. Even a vessel meeting the above functions may be unsatisfactory because it may provide too little capacity or alternatively, objectionable volume.

SUMMARY OF THE INVENTION

The present disclosure addresses the above stated situation by providing a modular cup including a tethered cap and a mouthpiece. Modules may be added or removed to vary holding capacity. The cup has at least one expansible handle movable from a compact stowed configuration to an extended deployed configuration. The cup has a mouthpiece module having either one of two styles of mouthpiece. One type is centered over the cylindrical body of the cup, and generally circular in cross section. The other type is located near the periphery of the cup, and is oval or otherwise non-circular in cross section.

DETAILED DESCRIPTION

Referring first to FIG. 1, according to at least one aspect of the disclosure, there is shown a modular drinking vessel 100 comprising base module 102, at least one intermediate module 104, and cap module 106. Base module 102 includes floor 108, lateral wall 110 projecting from the floor 108, and first connector 112 on the lateral wall 110. Intermediate module 104 includes lateral wall 114, second connector 116 at one edge 118 of lateral wall 114, second connector 116 being matingly compatible with first connector 116 of base module 102. In the example of FIG. 1, first and second connectors 112, 116 comprise matingly compatible screw threads. Intermediate module 104 includes third connector 120 at an opposed edge 122 of lateral wall 114. Intermediate module 104 is open at both ends 124, 126. Connecting intermediate module 104 to base module 102 increases fluid capacity of the latter.

Unless otherwise indicated, the terms “first”, “second”, etc., are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, e.g., a “second” item does not either require or preclude the existence of, e.g., a “first” or lower-numbered item, and/or, e.g., a “third” or higher-numbered item.

Cap module 106 comprises lateral wall 128 which is shorter (as indicated by arrow 130) than lateral wall 114 of intermediate module 104. Cap module 106 comprises fourth connector 132 at one end 134 of lateral wall 128, fourth connector 132 being matingly compatible with third connector 120 of intermediate module 104, and cover panel 136 at an opposed end 138 of the lateral wall 128. Cover panel 136 has a periphery (seen as surface 140 in FIG. 1) and a mouthpiece 142 including a drinking orifice 144. Cover panel 136 closes cap module 106 except at drinking orifice 144. Cover panel 136 includes cap 146, the latter attachable to cap module 106 and configured to entirely seal cover panel 136 and mouthpiece 142 from the external atmosphere. Flexible tether 148 tethers cap 146 to cap module 106, and may be fastened to cap module 106 and cap 146 by enlarged heads 180, rivets (not shown), or still other fasteners (none shown).

Flexible tether 148 is sufficiently long to bulge outwardly from modular drinking vessel 100 when modular drinking vessel 100 is assembled and cap 146 is installed thereon sufficiently to provide space for the hand or fingers (not shown) of a user to grasp flexible tether 148 as a carrying handle. Space for the hand or fingers is seen as arrows 150, 152.

Modular drinking vessel 100 has a longitudinal axis 154 extending centrally along the lengths of base module 102, intermediate module 104, and lateral wall 128 of cap module 106 when modular drinking vessel 100 is assembled. Assembly signifies that intermediate module 104 is tightly connected to base module 102, and cap module 106 is tightly connected to intermediate module 104. It is possible to include more than one intermediate module 104, as second connector 116 is compatible with third connector 120. Hence a series of intermediate modules 104 (only one is shown) could be connected together if desired.

Cap 146 connects to lateral wall 128 of cap module 106 in the following way. Cap module 106 has a fifth connector 156 on that side of cap module 106 opposite fourth connector 132. Cap 146 has a sixth connector 158 matingly complementing fifth connector 156. Fifth and sixth connectors 156, 158 collectively comprise a finite travel mechanical interlock. In the example of FIG. 1, fifth connector 156 comprises at least one L-shaped groove 160 formed in surface 140. Sixth connector 158 comprises at least one dog or interlock projection 162 which fits slidably in close cooperation with one L-shaped groove 160. When cap 146 is connected to cap module 106 by inserting interlock projection 162 into L-shaped groove 160 as far as possible in the vertical direction (as shown in FIG. 1), cap 146 is twisted so that interlock projection 162 passes towards distal end 164 of L-shaped groove 160. At this point, the end of L-shaped groove stops further rotation of cap 146 by interference. Hence the travel of interlock projection 162 is limited or finite. This connection is typical of those called bayonet connections, and will be referred to as a finite travel interlock. A finite travel interlock could take forms other than the bayonet connection described herein.

The number of L-shaped grooves 160, although shown as two in FIG. 1, could be only one, or if desired, more than two. Two interlock projections 160 are illustrated in FIG. 1. The number of interlock projections 162 is at least one, and if desired, more than one. The number of interlock projections 162 may be less than the number of L-shaped grooves 160, but cannot be greater.

In the example of FIG. 1, and referring also to FIG. 2, mouthpiece 142 is centrally located on cover panel 136 (i.e., is coaxial with the longitudinal axis 154) and is annular in a cross section taken along longitudinal axis 154.

Referring to FIGS. 1 and 3-7, modular drinking vessel 100 comprises at least one collapsible handle 166. Base module 102 has at least one slide track 168 extending along the exterior of and recessed into lateral wall 110. Handle 166 comprises flexible strap 170, first head or anchor 172 slidably engageable within slide track 168 at one end of flexible strap 170, and second head or anchor 174 slidably engageable with slide track 168 at the other end of flexible strap 170. First and second anchors 172, 174 can be spread apart to draw flexible strap 170 towards longitudinal axis 154 from a bulging deployed condition depicted in FIG. 6. First and second anchors 172, 174 can be drawn towards one another (as shown in FIG. 6) to cause flexible strap to bulge outwardly and expose a handhold for engaging the fingers (not shown) of a user. FIG. 7 depicts the bulging deployed condition of handle 166 in solid lines, and a flattened, spread apart stowed condition of handle 166 in broken lines. FIG. 5 shows handle 166 in the flattened, spread apart stowed condition, isolated from other components of base module 102.

Although only one handle 166 is shown in FIGS. 1, and 4-7, base module 102 may have two slide tracks 170 and two handles 166 (see FIG. 3). It should also be appreciated that slide track(s) 170 may be formed in intermediate module(s) 104 in place of or in addition to being formed in base module 102. Therefore, at least one of base module 102 and intermediate module 104 may have either one slide track 170, or alternatively, may have two slide tracks 170 extending along and on opposite sides of the exterior of the respective lateral wall(s) 110 or 114 thereof. Where two slide tracks 170 are provided for either base module 102 or intermediate module 104, two handles 166, each mountable to one of the two slide tracks 170 may be provided.

Referring to FIGS. 8 and 9, an option to mouthpiece 142 of FIGS. 1 and 2 is illustrated. In the option shown in FIGS. 8 and 9, mouthpiece 142 is located on cover panel 136 of cap module 106 proximate a periphery 176 of cover panel 136. Mouthpiece 142 has an oblong opening 178 having length generally parallel to periphery 176 of cover panel 136.

FIG. 8 shows another feature of modular drinking vessel 100. Cap 146 fits in close cooperation with mouthpiece 142 and cover panel 136, having an interior surface 182 reflecting external configuration of mouthpiece 142 and cover panel 136. The same cooperation may be provided with mouthpiece 142 and cover panel 136 of the example of FIG. 1.

Modular drinking vessel 100 may be fabricated from a suitable polymeric material, such as polyethylene terephthalate (PET), high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), and other substances. Base module 102 may be configured to contain a fluid capacity between eight and twelve fluid ounces, such as ten fluid ounces. Each intermediate module 104 has a fluid capacity between five and ten fluid ounces, such as seven ounces.

The invention may be thought of as a drinking vessel, such as the modular drinking vessel 100, in the absence of intermediate module(s) 104 and if desired, in the absence of cap module 106. The drinking vessel may comprise floor 108, lateral wall 110, slide track(s) 168, and handle(s) 166.

It should be understood that the various examples of the apparatus(es) disclosed herein may include any of the components, features, and functionalities of any of the other examples of the apparatus(es) disclosed herein in any feasible combination, and all of such possibilities are intended to be within the spirit and scope of the present disclosure. Many modifications of examples set forth herein will come to mind to one skilled in the art to which the present disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings.

Therefore, it is to be understood that the present disclosure is not to be limited to the specific examples presented and that modifications and other examples are intended to be included within the scope of the appended claims. Moreover, although the foregoing description and the associated drawings describe examples of the present disclosure in the context of certain illustrative combinations of elements and/or functions, it should be appreciated that different combinations of elements and/or functions may be provided by alternative implementations without departing from the scope of the appended claims.
