Description

Technical Field

[0001] This utility model relates to a rotating outer casing for cups and bowls. Background Technology

[0002] Cups and bowls are common containers, such as disposable paper cups or bowls, or cups and bowls made of other materials. Cups and bowls with outer shells provide insulation. This design envisions a cup and bowl with an outer shell, where the inner cup (or inner bowl, collectively referred to as the inner cup body) is encased in an outer shell. The outer shell has windows (forming a perforated structure), and it will rotate outside the inner cup body to allow viewing of different graphics and text on the surface of the inner cup body through the windows, providing a better display effect. This type of cup and bowl with an outer shell needs to ensure ease of assembly of the outer shell and its stability during rotation after assembly. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a cup and bowl container with a rotating outer shell, which can achieve stable and smooth rotation of the outer shell, unlike the available technical solutions in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rotating outer cup and bowl container, comprising an inner cup body and a rotating outer sleeve, the inner cup body comprising an inner cup body and an inner cup bottom, the rotating outer sleeve being fitted around the outer ring of the inner cup body, the rotating outer sleeve having a hollowed-out window, and the inner cup body having an outwardly flared edge at the cup mouth, characterized in that: the inner cup body is provided with a limiting part that limits the position of the rotating outer sleeve, the limiting part being the upper port of the bottom cup fitted around the lower part of the inner cup body or the limiting part being an inwardly concave annular groove on the inner cup body; the space between the limiting part and the outwardly flared edge of the inner cup body is a rotating assembly area for the rotating outer sleeve to be fitted, the rotating outer sleeve being fitted between the outwardly flared edge and the limiting part.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the bottom cup is fixedly connected to the body of the inner cup, the rotating outer sleeve is configured on the upper side of the bottom cup, the lower end of the rotating outer sleeve has a rolled edge, and the upper end of the bottom cup, which serves as a limiting part, includes a curved edge, with the rolled edge supported on the curved edge.

[0007] In addition, the bottom cup and the inner cup are connected and fixed by adhesive, ultrasonic welding or heat sealing. The curved edge is turned outward. The side wall of the bottom cup matches and abuts the inner cup body. The bottom of the bottom cup is located below the bottom of the inner cup.

[0008] Among them, the bottom rolled edge adopts an inward rolled edge, and the outward folded edge adopts an R rolled edge, a half R rolled edge, a folded and bonded edge, a square folded edge, a folded ∩-shaped edge, an outward folded flat edge, or an outward folded L-shaped edge; the bottom cup is formed by stamping a single piece of paper or by combining the cup cylinder and the cup bottom separately with rolled bottom.

[0009] For example, an annular groove is set at the lower part of the inner cup body, and the lower end of the rotating outer sleeve has a rolled edge, which is an inward rolled edge. The rolled edge of the rotating outer sleeve is connected and supported in the annular groove.

[0010] There is a rotational fit gap between the outer wall of the inner cup body and the inner wall of the rotating outer sleeve, and the rotational fit gap is located between the upper and lower ends of the rotating outer sleeve.

[0011] For example, the rotational fit clearance is controlled between 0.5 and 1.2 mm.

[0012] In addition, the upper end of the rotating outer sleeve abuts against the lower part of the outward-flaring edge of the inner cup body.

[0013] For example, the top end of a rotating jacket is flat, and the rotating jacket is a jacket without a rolled edge at the top.

[0014] The inner cup is made of paper or plastic, and the inner cup body is a rotating body. The bottom cup is made of paper or plastic, and the rotating outer sleeve is made of paper.

[0015] The beneficial effects of this utility model are as follows: In this rotating outer cup and bowl container, a corresponding bottom cup or an inwardly concave annular groove is provided on the inner cup body, which cooperates with the outwardly turned edge above to form a rotating assembly area for the rotating outer jacket, thus forming this type of rotating outer cup and bowl container. Furthermore, the rotating outer jacket in this cup and bowl rotates stably and smoothly, without easily getting stuck. The bottom cup added to the inner cup body has a relatively stable overall structure. Connected to the outside of the inner cup body, it not only strengthens the inner cup body but also provides stable support and limiting effect for the rotating outer jacket, and also increases the overall height of the cup and bowl (with the inner cup volume remaining unchanged), resulting in a visually larger cup and bowl. The annular groove on the inner cup body is concave from the outside to the inside, making it relatively easy to manufacture. It avoids processing from the narrow area at the bottom of the cup, forming a circular groove directly on the inner cup body from the outside. This eliminates the need for additional components, resulting in a more compact structure. The annular groove also has relatively good overall structural strength, providing good support and connection for the rotating outer jacket. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Referring to the accompanying drawings, in this embodiment, the rotating outer cup and bowl container includes an inner cup body 1 and a rotating outer sleeve 2. The inner cup body 1 includes an inner cup body 11 and an inner cup bottom 12, wherein the inner cup bottom 12 is located at the bottom of the inner cup body 11 to form a container. The rotating outer sleeve 2 is fitted around the outer ring of the inner cup body 11 (i.e., the outer periphery of the inner cup body 11; typically, the inner cup body 11 is a rotating body, and the outer ring is a circular ring). In addition, the rotating outer sleeve 2 is provided with a cutout window 21 so that a part of the inner cup body 11 can be exposed through the cutout window 21. The rotating outer sleeve 2 rotates and changes position within it, and the cutout window 21 can display different areas of the inner cup body 11. The inner cup body 11 has an outwardly flared edge 13 at its rim, and a limiting part 3 that limits the position of the rotating outer sleeve 2. This creates an upper and lower structure with the outwardly flared edge 13 on top and the limiting part 3 on the bottom for mounting the rotating outer sleeve 2. For example, the limiting part 3 can be the upper port 40 of the bottom cup 4 fitted onto the lower part of the inner cup body 1, or the limiting part 3 can be an inwardly recessed annular groove 50 on the inner cup body 11. The area between the limiting part 3 and the outwardly flared edge 13 of the inner cup body 11 is a rotating assembly area for mounting the rotating outer sleeve 2, forming a stable and smooth rotation area for the rotating outer sleeve 2. The rotating outer sleeve 2 is matched between the outwardly flared edge 13 and the limiting part 3, and the upper and lower ends of the rotating outer sleeve 2 can be well integrated into the cup and bowl, resulting in better overall structure, stability, compactness, and refinement.

[0031] In this rotating outer cup and bowl container, a corresponding base cup 4 or an inwardly recessed annular groove 50 is provided on the inner cup body 1, which cooperates with the upper outwardly turned edge 13 to form a rotating assembly area for the rotating outer sleeve 2, thus forming this rotating outer cup and bowl container. Furthermore, the rotating outer sleeve 2 in this type of cup and bowl rotates stably and smoothly, without easily getting stuck. The base cup 4, attached to the inner cup body 1, has a relatively stable overall cup structure. Connected to the outside of the inner cup body 1, it not only strengthens the inner cup body 1 but also provides stable support and limiting effect for the rotating outer sleeve 2, and also increases the overall height of the cup and bowl (with the volume of the inner cup body 1 remaining unchanged), resulting in a visually larger cup and bowl. The annular groove 50 on the inner cup body 1 is concave from the outside to the inside, which is relatively easy to manufacture. It avoids processing and manufacturing from the narrow area at the bottom of the cup. The annular groove 50 is formed directly on the inner cup body 1 from the outside, without the need for additional parts, making the structure more compact. The annular groove 50 has relatively good structural strength and good support effect, and can cooperate with the rotating outer jacket 2 for support and connection.

[0032] Based on the above embodiments, the following optimizations or further explanations can be made.

[0033] Taking the base cup 4 as an example: The base cup 4 is fixedly connected to the outside of the inner cup body 1. The rotating outer sleeve 2 is disposed on the upper side of the base cup 4. In addition, the lower end of the rotating outer sleeve 2 has a rolled edge 22. The upper end 40 of the base cup 4, which serves as the limiting part 3, includes a curved edge 41 (an edge that can be formed by bending or folding). The rolled edge 22 is supported on the curved edge 41, forming a structure in which the rolled edge 22 is supported and limited by the curved edge 41. The rolled edge 22 not only enhances the overall strength of the rotating outer sleeve 2, but also enhances the fit between it and the base cup 4 (the curved edge 41), enhancing the rotational stability and smoothness between the rotating outer sleeve 2 and the base cup 4. The base cup 4 with the curved edge 41 also has relatively good overall strength, which can improve the strength of the inner cup body 1 and the entire cup bowl. The base cup 4 and the inner cup body 1 can be connected and fixed by adhesive, ultrasonic welding, or heat sealing (i.e., heat bonding). The adhesive bonding technology is relatively mature. The curved rim 41, with its outward-curved edge (i.e., bent or folded outwards), ensures a tighter and more secure fit between the sidewall of the base cup 4 and the inner cup body 11, preventing the base cup 4 from easily detaching from the inner cup body 11. The outer cup bottom 42 of the base cup 4 is located below the inner cup bottom 12. The lower rolled edge 22 can be an inward-curved edge (such as an R-curved edge or a semi-R-curved edge) forming an inward-curved structure. This creates a certain gap between the rotating cup sleeve and the inner cup body 1, reducing contact and allowing for smoother rotation. The outward-curved edge can be an R-curved edge, a semi-R-curved edge, a folded edge, a square folded edge, a folded ∩-shaped edge, an outward-curved flat edge, or an outward-folded L-shaped edge, among other structures. These can be manufactured using mature methods such as rolling, stamping, or die pressing. In addition, the bottom cup 4 is formed by stamping a single piece of paper or by combining the cup tube and the bottom separately with a rolled bottom (such as rolling bottom connection, that is, the bottom cup 4 can also adopt the conventional short cup paper cup structure).

[0034] Taking the annular groove 50 as an example: The annular groove 50 is located at the lower part of the inner cup body 1, resulting in a relatively good overall structural proportion. The lower end of the rotating outer sleeve 2 has a rolled edge 22, which is connected and supported (i.e. embedded) in the annular groove 50, forming a rotating support structure with the rolled edge 22 surrounding the annular groove 50. The rolled edge 22 not only enhances the overall strength of the rotating outer sleeve 2 but also strengthens the fit with the annular groove 50, improving the matching degree, rotational stability, and smoothness between the rotating outer sleeve 2 and the annular groove 50. The rolled edge 22 can be an inward rolled edge (such as an inward R-roll or a half R-roll), forming an inward rolled edge structure. Alternatively, it can create a certain gap between the rotating cup sleeve and the inner cup body 1, reducing mutual contact and making rotation smoother. Assembly is also relatively convenient in this structure; simply put the rotating outer sleeve 2 over the inner cup body 1, and the assembly can be completed smoothly by utilizing their slight deformation.

[0035] In addition, a rotational fit clearance is provided between the outer wall of the inner cup body 11 and the inner wall of the rotating outer sleeve 2. This rotational fit clearance is located between the upper and lower ends of the rotating outer sleeve 2 to allow for rotation. The rotational fit clearance can be controlled between 0.5 and 1.2 mm to ensure structural stability and prevent wobbling while allowing for rotation.

[0036] For example, the upper end (i.e., the upper port) of the rotating outer sleeve 2 abuts against the lower part of the outer edge 13 of the inner cup body 11. There is no need for additional engagement between the upper end (port) of the rotating outer sleeve 2 and the outer edge 13 of the inner cup body 11 (such as an outward R-curled edge or a half-R-curled edge). It simply abuts against the outer edge 13, preventing the upper end (port) of the rotating outer sleeve 2 from being exposed. For instance, the upper port of the rotating outer sleeve 2 may use a flat end 23, meaning the rotating outer sleeve 2 is a sleeve without a rolled edge at the upper end. This simplifies the structure and eliminates the need for additional processing of the upper port. The inner cup body 1 is made of paper or plastic, the base cup 4 is made of paper or plastic, and the rotating outer sleeve 2 is made of paper. For paper cup machine manufacturers or paper cup makers, this allows for direct upgrades to existing models or processes.
