Description

Liquid container assembly

Technical Field

The present utility model relates to a liquid container, and more particularly, to a liquid container assembly having an upper cover.

Background

A typical cup is a container having an opening to which a lid may be attached to cover the opening. The cap is removed from the opening to drink the water or beverage in the cup. At this time, if the lid is separate from the cup, the lid often requires additional grasping or placement (e.g., on a table) by the user; if the lid is still connected to the cup (e.g., by a string or a hinge structure therebetween), the lid may shake or rotate relative to the cup while drinking water or beverage from the cup. Both of the foregoing cases cause a little inconvenience to the user.

Disclosure of Invention

In view of the problems in the prior art, it is an object of the present utility model to provide a liquid container assembly.

A liquid container assembly according to one embodiment of the present utility model includes a cup-shaped container and an upper lid. The cup-shaped container is provided with a liquid accommodating space and a container opening communicated with the liquid accommodating space. The upper lid selectively removably engages with the container opening to cover the container opening or with the cup-shaped container via an engagement structure to firmly attach to one side of the cup-shaped container and expose the container opening. Thus, when the upper cover is firmly attached to the side of the cup-shaped container to expose the container opening, a user can access the contents (such as water, beverage and the like) of the liquid containing space through the container opening without additionally placing the upper cover (such as holding or placing on a table), and without worrying about shaking or rotating the upper cover relative to the cup-shaped container to affect access.

The advantages and spirit of the present utility model will be further understood from the following detailed description of the utility model and the accompanying drawings.

Detailed Description

Please refer to fig. 1 to 4. The liquid container assembly 1 according to an embodiment comprises a cup-shaped container 12 and an upper lid 14. The cup-shaped container 12 has a liquid accommodating space 12a (indicated with reference to fig. 5) and a container opening 12b communicating with the liquid accommodating space. The upper lid 14 is selectively removably engaged (e.g., by threaded engagement) with the container opening 12b to cover the container opening 12b (as shown in fig. 1) or removably engaged with the cup-shaped container 12 via an engagement structure to firmly attach to one side of the cup-shaped container 12 and expose the container opening 12b (as shown in fig. 4). Thus, the user can selectively attach the upper lid 14 firmly to the side of the cup-shaped container 12, and access the contents (e.g., water, beverage, etc.) of the liquid receiving space 12a through the container opening 12b without taking care that the upper lid 14 is shaken or rotated relative to the cup-shaped container 12 to affect access.

Please refer to fig. 5. In this embodiment, the engagement structure includes a locking block 161, a locking groove 162 matched with the locking block 161, a hook 163, a locking groove 164 matched with the hook 163, a slot 165, and a protruding plate 166 matched with the slot 165. The engaging block 161 and the hook 163 are located in the cup-shaped container 12, the engaging groove 162 and the hook 164 are located in the upper cover 14, the slot 165 is located in the engaging block 161, and the projection 166 is located in the engaging groove 162. The upper lid 14 is moved from bottom to top (in the direction of movement indicated by the arrow in fig. 3) by the engagement blocks 161 being snapped into the snap grooves 162, the lugs 166 being snapped into the slots 165, and the snaps 163 hooking the snap grooves 164 to firmly attach to the side of the cup-shaped container 12 and expose the container opening 12b (as shown in fig. 4). Thus, the engagement structure can structurally constrain the upper cover 14 in three directions D1, D2, D3 (shown by double-headed arrows). Thereafter, the upper lid 14 is separated from the cup-shaped container 12 by disengaging the hooks 163 from the slots 164 and moving the upper lid 14 in the opposite direction (i.e., downward parallel to the direction D1).

Wherein, the slot 165 is formed on the engaging block 161 and extends along a U-shaped path on three sides of the engaging block 161, and the convex plate 166 is correspondingly disposed in the engaging groove 162 and extends along a U-shaped path; this structural arrangement helps the upper lid 14 to be firmly attached to the side of the cup-shaped container 12. In practice, the slot 165 may be disposed in the engaging groove 162, and the protruding plate 166 is disposed on the engaging block 161 correspondingly; the engaging block 161 may be provided on the upper lid 14, and the engaging groove 162 may be provided on the cup-shaped container 12. In addition, the structural engagement of the slot 165 and the protruding plate 166 can provide structural restraint of the upper cover 14 in the direction D3, and in practice, the slot 165 and the protruding plate 166 can be removed, and other structures can be used to achieve structural restraint in the direction D3. For example, the engagement slot 162 is implemented as a dovetail slot, and the engagement block 161 is a mating slider, which configuration also provides structural restraint of the upper cover 14 in the direction D3.

In addition, in the present embodiment, the engagement structure includes a pressing key 167 and an elastic restoring member 168. The pressing key 167 is pivotally connected to the cup-shaped container 12 (the pivotal connection position is shown as a cross in fig. 5), and the resilient restoring member 168 (such as, but not limited to, a coil spring) is tightly abutted between the pressing key 167 and the cup-shaped container 12, and the hook 163 is disposed on the pressing key 167. The resilient return member 168 pushes the push key 167 outward to hold the hook 163 in the hook holding groove 164. The hook 163 is disengaged from the groove 164 by pressing the push button 167. The structure is configured to enable the hook 163 to be elastically engaged with the slot 164. In practice, the elastic engagement can be realized by other elastic structures, such as cantilever structures. The hook 163 and the slot 164 are engaged in other ways, such as by the elasticity of the material itself, so that the hook 163 is engaged into the slot 164.

In addition, as shown in fig. 2 to 4, in the present embodiment, the upper cover 14 has an inner side surface 14b. The engaging structure disposed on the upper cover 14 is disposed on the inner side surface 14b (wherein the engaging groove 162 of the engaging structure is concavely formed on the inner side surface 14b, the engaging groove 164 is formed at the bottom of the engaging groove 162, and the protruding plate 166 is formed protruding from the side wall of the engaging groove 162). When the upper lid 14 is engaged with the container opening 12b, the inner side surface 14b of the upper lid 14 faces the inside of the cup-shaped container 12. When the upper lid 14 is firmly attached to the side of the cup-shaped container 12, the inner side surface 14b of the upper lid 14 faces the outer surface 12c of the cup-shaped container 12 and conforms to the contour of the outer surface 12 c. In this embodiment, the inner side surface 14b and the corresponding part of the outer surface 12c are arc-shaped; but are not limited in practice, e.g., both are planar or other contours.

In addition, as shown in fig. 1 and 4, in the present embodiment, the upper cover 14 has a handle 14a. When the upper lid 14 is engaged with the container opening 12b of the cup-shaped container 12, the user can grasp the handle 14a to lift the liquid container assembly 1. In practice, the liquid container assembly 1 may be used as a thermos bottle. When the upper lid 14 is firmly attached to the side of the cup-shaped container 12, the user can grasp the handle 14a to control the posture of the cup-shaped container 12; in practical applications, the liquid container assembly 1 may be designed to be used as a mug. In addition, in the present embodiment, the connecting structure disposed on the upper cover 14 is located on the inner side surface 14b, but the implementation is not limited thereto, for example, the connecting structure is disposed around the upper cover 14. In the present embodiment, the upper cover 14 is moved from bottom to top to be attached to the side of the cup-shaped container 12, but the implementation is not limited thereto. In practice, the structural arrangement of the engagement structure may be designed to allow the lid 14 to be moved in different directions for attachment to the sides of the cup-shaped container 12; for example, the lid 14 may be moved from top to bottom to attach to the sides of the cup-shaped container 12 by reversing the engagement structure provided on the cup-shaped container 12.

Please refer to fig. 6 and 7. In this embodiment, the cup-shaped container 12 includes a cup 122 and a cap 124. The cap 124 includes a cap 1242, a plug 1244, and an elastic member 1246. The cover 1242 has a plurality of passages 1242a. The plug 1244 is movably disposed on the cover 1242 corresponding to the channel 1242a, and the elastic member 1246 (such as, but not limited to, a coil spring) is tightly abutted between the plug 1244 and the cover 1242. The cap 124 is removably coupled to the opening 122a of the cup 122 (e.g., by threaded engagement) via the cap 1242 to form the liquid receiving space 12a, and the passageway 1242a communicates with the liquid receiving space 12a, with the opening of the cap 1242 being the container opening 12b. When the upper lid 14 is detachably engaged with the container opening 12b to cover the container opening 12b, the upper lid 14 pushes the stopper 1244 to close the passage 1242a, i.e., to seal the liquid-containing space 12a (as shown in fig. 8). Also, when the upper cover 14 is removed from the container opening 12b, the elastic member 1246 pushes the stopper 1244 to open the passage 1242a, so that the liquid accommodating space 12a communicates with the outside via the passage 1242a (as shown in fig. 5).

In addition, in the present embodiment, the cover 1242 has a plurality of through slots 1242b, the plug 1244 includes a main body 12442 and a plurality of hooking portions 12444 extending from the main body 12442, and the hooking portions 12444 slidably pass through the through slots 1242b. The hooking portion 12444 can hook the edge of the corresponding through groove 1242b, so as to prevent the plug 1244 from being completely separated from the cover 1242. The through grooves 1242b are uniformly distributed on the cover 1242 at equal circumferential angles, and the hooking portions 12444 are also uniformly distributed on the main body 12442 at equal circumferential angles. In principle, the number of the through grooves 1242b and the hooking portions 12444 is more than two, so that the plug 1244 can slide smoothly with respect to the cover 1242. In practice, the plug 1244 is movably disposed on the cover 1242 in other configurations, such as the plug pivotally connected to the cover 1242, and the elastic member 1246 is implemented as a torsion spring, which can also produce the effect of closing and opening the passage 1242a.

In addition, in the present embodiment, the cup-shaped container 12 is designed in a detachable manner, which facilitates the manufacture of the cup 122 and the cup cover 124 with different materials, and facilitates the design and manufacture of the structure. For example, the cup 122 is mainly made of stainless steel material, so that the heat insulation structure is convenient to form; the cap 124 is primarily plastic to facilitate a careful construction. But is not limited to this in practice. In practice, the engagement structure provided on the cup-shaped container 12 may be provided on the cup 122 instead, for example, by implementing the engagement structure as a piece and securing it to the outside surface of the cup 122. Also, in practice, the cup-shaped container 12 itself may be implemented from a single piece, such as a structure resembling a typical glass.

In practice, the engagement structure (the top cover 124 is firmly attached to the side of the cup-shaped container 12) may be implemented in other structural configurations. For example, in the embodiment shown in fig. 9, the engagement structure is similar to the engagement structure of the liquid container assembly 1, so that the reference numerals of the liquid container assembly 1 are basically used. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted. The engagement structure shown in fig. 9 further includes a first magnetic member 361a and a second magnetic member 362a (both of which are shown in phantom in the disposed positions) as compared to the engagement structure of the liquid container assembly 1. In fig. 9, the pressing key 363a of the engagement structure is slidably disposed on the cup-shaped container 32a, the hook 163 is disposed on the pressing key 363a, the first magnetic member 361a is fixedly connected to the pressing key 363a, and the second magnetic member 362a is disposed on the upper cover 34a. In the process of detachably engaging the upper cover 34a with the cup-shaped container 32a via the engaging structure, the first magnetic member 361a and the second magnetic member 362a generate a magnetic attraction force, and the magnetic attraction force drives the pressing key 363a (together with the hook 163) to extend outwards. After the upper cover 34a is firmly attached to the cup-shaped container 32a, the magnetic attraction force can hold the hook 163 to hook the hook groove 164 (not shown in fig. 9). Then, the hook 163 is separated from the slot 164 by pressing the pressing key 363a, so that the upper cover 34a can slide downward to be separated from the cup-shaped container 32 a. In practice, the engaging block 161 may be slidably disposed on the cup-shaped container 32a, and a magnetic member is fixedly disposed on the engaging block 161. When the second magnetic member 362a approaches the magnetic member, the magnetic member is attracted to drive the engaging block 161 to extend outwards, so that the protruding plate 166 (not shown in fig. 9) on the upper cover 34a can smoothly slide into the slot 165 on the engaging block 161, thereby completing the engagement between the upper cover 34a and the side of the cup-shaped container 32 a.

For another example, in the embodiment shown in fig. 10, the engagement structure includes an annular groove 361b and a C-shaped resilient member 362b. An annular groove 361b is formed on the cup-shaped container 32b, and a C-shaped elastic member 362b is provided on the upper cover 34b. The opening of the C-shaped resilient member 362b is smaller than the minimum outer diameter of the annular recess 361b. When the upper cover 34b is firmly attached to the side of the cup-shaped container 32b, the C-shaped elastic member 362b snaps into the annular groove 361b. In addition, in the present embodiment, the C-shaped elastic member 362b is pivotally connected to the upper cover 34b, so that the upper cover 34b can be smoothly connected to the container opening 322b of the cup-shaped container 32b by rotating the C-shaped elastic member 362b (relative to the upper cover 34 b); at this time, the C-shaped elastic member 362b is accommodated within the cup-shaped container 32 b. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 11, the engagement structure includes a protrusion 361c and a hole 362c. The boss 361c is provided to the cup-shaped container 32c, and the hole 362c is provided to the upper cover 34c. When the upper cover 34c is firmly attached to the side of the cup-shaped container 32c, the boss 361c is firmly inserted into the hole 362 c; wherein, for example but not limited to, the stud 361c engages the aperture 362c with an interference fit. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 12, the engagement structure includes a hole 361d and a post 362d. The hole 361d is provided in the cup-shaped container 32d, and the boss 362d is provided in the upper cover 34d and has an external thread. When the upper cover 34d is firmly attached to the side of the cup-shaped container 32d, the boss 362d is screwed into the hole 361d by the external screw thread to be firmly inserted into the hole 361. In practice, internal threads may be formed on the inner wall of the hole 361d to enhance the bonding strength between the hole 361d and the boss 362d. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 13 and 14, the engagement structure includes a protruding ring 361e and a resilient clip structure 362e. The protruding ring 361e is disposed on the cup-shaped container 32e, and the elastic clip structure 362e is disposed on the upper cover 34e. When the upper cover 34e is firmly attached to the side of the cup-shaped container 32e, the resilient clip structure 362e clips the protruding ring 361e (as shown in fig. 14). For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 15, the engagement structure includes a suction cup 361f. The suction cup 361f is provided on the upper cover 34f. When the upper cover 34f is firmly attached to the side of the cup-shaped container 32f, the suction cup 361f is sucked to the outer surface of the cup-shaped container 32 f. In this embodiment, the suction cup 361f has a tab 362f that facilitates the user in breaking the low pressure space formed between the suction cup 361f and the outer surface of the cup-shaped container 32f to remove the upper lid 34f from the cup-shaped container 32 f. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 16 (in which the cup-shaped container 32g is shown in cross-section), the engagement structure includes two hooks 361g and two slots 362g. The two hooks 361g are disposed opposite to each other on the upper cover 34g, and the two engaging grooves 362g are formed opposite to each other on the cup-shaped container 32g. The two hooks 361g hook the two slots 362g when the upper cover 34g is firmly attached to the side of the cup-shaped container 32g. Wherein the two slots 362g are implemented with opposite sides of a recess 363g. In practice, at least one of the hooks 361g is movable in the direction D1 (e.g. the button 364g disposed on the upper cover 34g is exposed to couple the hooks 361g, so that the user can operate the hooks 361g conveniently) to enter the recess 363g. In practice, the two hooks 361g may be implemented by an elastic structure, so that the two hooks 361g can elastically deform to enter the recess 363g and rebound to hook the two slots 362g. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 17, the engagement structure includes a resilient clip structure 361h and a cup rim 322h of the cup-shaped container 32h that is held by the resilient clip structure 361 h. The elastic clip structure 361h is disposed on the upper cover 34h. When the upper lid 34h is firmly attached to the side of the cup-shaped container 32h, the resilient clip structure 361h spans across and clips the cup rim 322h of the cup-shaped container 32 h. The elastic clip structure 361h can be controlled to open and close by exposing the button 362h arranged on the upper cover 34h, so that the operation of a user is facilitated. In addition, the cup edge 322h has a positioning slot 324h at a corresponding position for the elastic clamping structure 361h to clamp and provide positioning effect. In addition, the end of the elastic clamping structure 361h is sleeved with an anti-slip sleeve (such as silica gel or rubber material), which is helpful for stabilizing the clamping cup edge 322h, and also has the effect of protecting the cup edge 322h and the end of the elastic clamping structure 361 h. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 18, the engagement structure is similar to the engagement structure of the liquid container assembly 1, so that the reference numerals of the liquid container assembly 1 are basically used. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted. The engagement structure shown in fig. 18 further includes a receptacle 361i formed on the engaging block 161, a latch 362i, and a through hole 363i formed on the upper cover 34i (e.g., exposed from the sidewall of the engaging groove 162) as compared with the engagement structure of the liquid container assembly 1. When the upper cover 34i is firmly attached to the side of the cup-shaped container 32i, the engagement block 161 is engaged into the engagement groove 162, the through-hole 363i is aligned with the insertion hole 361i, and the latch 362i is inserted through the through-hole 363i and into the insertion hole 361 i. In practice, latch 362i may also be inserted into receptacle 361i to prevent rattling when upper lid 34i is engaged to container opening 322i of cup-shaped container 32 i. In addition, in the present embodiment, a connecting rope 364i connects the latch 362i and the engaging block 161 (or the cup-shaped container 32 i), so as to prevent the latch 362i from being lost.

For another example, in the embodiment shown in fig. 19, the engagement structure comprises a touch fastener assembly comprising two touch fasteners 361j,362j secured to the cup-shaped container 32j and the upper cover 34j, respectively. The two contact fasteners 361j,362j are detachably engaged with each other when the upper cover 34j is firmly attached to the side of the cup-shaped container 32 j. In practice, the touch fastener assembly may be velcro, velcro tape (Hook and loop fasteners or hook-and-loop fasteners), 3M Dual Lock, etc. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 20, the engagement structure includes a magnet 361k (the position of which is shown in phantom). The magnet 361k is disposed on the upper cover 34k, and the cup-shaped container 32k has a magnetic portion (for example, the cup-shaped container 32k is made of paramagnetic material, or a paramagnetic object or magnet is embedded or fixed on the cup-shaped container 32 k). When the upper cover 32 is firmly attached to the side of the cup-shaped container 32k, the magnet 361k generates a magnetic attraction with the magnetic portion of the cup-shaped container 32k to keep the upper cover 34k attached to the cup-shaped container 32 k. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

In addition, as described above with respect to the cup-shaped container 12 of the liquid container assembly 1 (see fig. 5 and 8), the elastic member 1246 is tightly abutted between the stopper 1244 and the lid 1242 in the cup cover 124, and participates in the control of opening and closing the channel 1242a on the lid 1242. However, the opening and closing of the upper channel 1242a of the upper cover 1242 may be implemented by other structural arrangements. For example, in the embodiment of fig. 21, cap 424a is similar in structure to cap 124 of liquid container assembly 1, so that reference numerals for liquid container assembly 1 are principally used. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted. The cap 424a of fig. 9 further includes a first magnet 4241a and a second magnet 4242a as compared to the cap 124 of the liquid container assembly 1. The first magnet 4241a is provided in the cover 1242, and the second magnet 4242a is provided in the plug 1244. The first magnet 4241a and the second magnet 4242a are disposed opposite to each other and generate a magnetic repulsive force. The cap 424a replaces the effect of the elastic member 1246 of the cap 124 of the liquid container assembly 1 with the magnetic repulsive force, so that the cap 424a can be fitted in the cup-shaped container 12 of the liquid container assembly 1 instead of the cap 124. In other words, when the upper lid 14 is removably engaged with the container opening 12b to cover the container opening 12b, the upper lid 14 pushes against the stopper 1244 to close the passage 1242a (similar to fig. 8); when the upper lid 14 is removed from the container opening 12b, the magnetic repulsive force pushes the stopper 1244 to open the passage 1242a (as shown in fig. 21; in which the flow direction of the contained liquid is indicated by a bold arrow).

For another example, in the embodiment shown in fig. 22, the cap 424b includes a cover 4241b, a plug 4242b and a push-down spring 4243b. The plug 4242b is connected to the cover 4241b via a push-down rebound device 4243b. The push-down spring 4243b may provide two stop positions for the plug 4242b relative to the cover 4241 b; in practice, the push-on rebound device 4243b may be implemented by a rebound device assembly resembling that used by a cabinet door. Thereby, the plug 4242b can close or open the passage 4244b of the cover 4241b by the action of the push-type spring-back device 4243b (for example, the plug 4242b is directly pushed by the user) (wherein, fig. 22 shows the passage 4244b in an opened state, and the thick line arrow in the figure indicates the flowing direction of the liquid). In addition, the cap 424b of the present embodiment may be fitted into the cup-shaped container 12 of the liquid container assembly 1 instead of the cap 124. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment shown in fig. 23, the cap 424c includes a cover 4241c and a stopper 4242c. The stopper 4242c is pivotally connected to the cover 4241 c. The shutter 4242c has a through hole 4243c corresponding to the passage 4244c of the cover 4241 c. When the shutter 4242c is rotated (e.g., directly rotated by a user) to align the through-hole 4243c with the channel 4244c, the liquid receiving space 420c (formed by the connection of the cup cap 424c with the cup 422 c) communicates with the container opening 421c (i.e., the opening of the cover 4241 c) via the through-hole 4243c and the channel 4244c. In addition, the cap 424c of the present embodiment may be fitted into the cup-shaped container 12 of the liquid container assembly 1 instead of the cap 124. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

For another example, in the embodiment of fig. 24, cap 424d includes a cover 4241d and a plug 4242d. The plug 4242d is screwed into the cap 4241d via a threaded formation 4243 d. The plug 4242d is rotatable (e.g., directly rotated by a user) relative to the cap 4241d via a threaded structure 4243d to close or open the passageway 4244d (wherein fig. 24 shows the passageway 4244d in an open state, with bold arrows indicating the direction of flow of the contained liquid). In addition, the cap 424d of the present embodiment may be fitted into the cup-shaped container 12 of the liquid container assembly 1 instead of the cap 124. For other descriptions of the components of the present embodiment, please refer to the related descriptions of the same named elements in the liquid container assembly 1, and the descriptions are omitted.

The foregoing description is only of the preferred embodiments of the utility model, and all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
