Summary of the Invention

Problems to be Solved by the Invention

[0005] The paired container of the first embodiment was designed with the premise that the inner container would be replaceable, resulting in an inferior overall design for both the inner and outer containers. The inner container was primarily for replacement, and the outer container served primarily as a stand for the inner container, establishing a fixed image and function. On the other hand, the paired container of the second embodiment had the characteristic of allowing the shape of the inner container to be visually recognized, but the inner and outer containers were joined together and could not be separated, representing a single design form of a single container.

[0006] One aspect of this disclosure may or may not involve an inner container being a refillable container, and one of its objectives is to provide a pair of containers, or an inner container or frame, that have excellent integration between the inner container and the frame, while allowing the inner container to be removed from the frame that serves as a stand. One aspect of this disclosure aims to provide a pair of containers, or an inner container or frame constituting such a pair of containers, that at first glance appear to be a single container rather than a pair of containers. One aspect of this disclosure aims to provide a pair of containers, or an inner container or frame, that offers high safety at the attachment point of the inner container when the inner container is attached to the frame. One aspect of this disclosure aims to provide a pair of containers with excellent design, or an inner container or frame that constitutes such a container.

[0007] Furthermore, the description of these issues does not preclude the existence of other issues. Also, one aspect of this disclosure is not required to solve all of these issues. Moreover, it is possible to extract other issues from the description, drawings, and claims. [Means for solving the problem]

[0008] One aspect of the present disclosure provides a pair of containers comprising an inner container, a frame, and a nozzle for dispensing the contents of the inner container, wherein the inner container is detachable from the frame, the frame having a mounting recess into which the inner container is attached and detached, and a reinforcing projection protruding from the mounting recess, the inner container having a camouflage portion that complements the recess of the mounting recess when mounted in the mounting recess, and the connection between the inner container, frame, and nozzle can be strengthened by tightening the reinforcing projection together with the neck of the inner container using the screw cap of the nozzle.

[0009] One aspect of this disclosure is a pair of containers comprising an inner container, a frame, and a nozzle for dispensing the contents of the inner container, wherein the inner container is detachable from the frame, the frame having a mounting recess into which the inner container is attached and detached, and a reinforcing projection protruding from the mounting recess, the inner container having a camouflage portion that complements the recess of the mounting recess when attached to the inner container, and the pair of containers in which the inner container, frame, and nozzle can be strengthened by tightening the reinforcing projection together with the neck portion of the inner container with the screw cap of the nozzle, so that when the inner container is attached to the frame, the mounting recess formed in the frame is complemented by the camouflage portion formed in the inner container, so that it appears as if there is no mounting recess, and the pair of containers in which the inner container and frame are highly integrated. Furthermore, the reinforcing projection strengthens the bond between the inner container and the frame, preventing the inner container from easily coming off the frame during use. Therefore, it is a pair of containers that is easy to use despite being a pair of containers.

[0010] One aspect of the present disclosure provides a pair of containers comprising an inner container and a frame, wherein the inner container is detachable from the frame, the frame having a mounting recess into which the inner container is attached and detached, and the inner container having a camouflage portion that complements the recess of the mounting recess when attached to the mounting recess. One aspect of the present disclosure is a pair of containers comprising an inner container and a frame, wherein the inner container is detachable from the frame, the frame having a mounting recess into which the inner container is attached, and the inner container having a camouflage portion that complements the recess of the mounting recess when attached to the mounting recess. As a result, when the inner container is attached to the frame, the mounting recess formed in the frame is complemented by the camouflage portion formed in the inner container, making it appear as if there is no mounting recess, and resulting in a pair of containers with excellent integration between the inner container and the frame.

[0011] One aspect of the present disclosure provides a pair of containers in which the camouflage portion extends from the neck of the inner container toward the opening of the mounting recess, and its end is formed in a shape that smoothly connects with the outer frame lines of the frames on both sides of the camouflage portion. One aspect of the present disclosure is a pair of containers in which the camouflage portion extends from the neck of the inner container toward the opening of the mounting recess, and its end is formed in a shape that smoothly connects the outer frame lines of the frames on both sides of the camouflage portion. As a result, even if the outer frame line of the frame is cut out due to the formation of the mounting recess, the camouflage portion fills the cut-out portion, making the outer frame line of the frame appear continuous, and the pair of containers has excellent integration between the inner container and the frame.

[0012] One aspect of the present disclosure provides a pair of containers in which the frame has a support portion for supporting the inner container, and the camouflage portion has a mounting portion having an engagement portion for the support portion. One aspect of this disclosure provides a pair of containers in which the frame has a support portion for supporting the inner container, and the camouflage portion has a mounting portion having an engagement portion for the support portion. Because the engagement portion is located on the camouflage portion, which extends beyond the neck portion and is longer than the diameter of the neck portion, the engagement area can be made wider than when the frame is engaged only with the portion corresponding to the neck portion. Therefore, the support of the inner container can be made more secure.

[0013] One aspect of the present disclosure provides a pair of containers in which the support portion of the frame is formed as a projection protruding from the wall surface of the frame, and the engagement portion of the inner container is formed as a groove from the wall surface of the mounting portion. In one aspect of this disclosure, the support portion of the frame is formed as a projection protruding from the wall surface of the frame, and the engagement portion of the inner container is formed as a groove from the wall surface of the mounting portion, forming a pair of containers. As a result, the engagement structure or support structure between the inner container and the frame is such that the projection portion of the frame is fitted into the groove portion of the inner container. With this structure, the inner container can be firmly engaged with the frame, and the support performance for supporting the inner container can be improved. Furthermore, although the frame, which does not need to be replaced, generally has a longer service life than the inner container, the projection shape of the support portion of the frame makes it less likely for dirt to adhere to it compared to when it is formed as a groove, and even if dirt does adhere, it is easier to remove. Therefore, it is easier to keep the frame, which tends to accumulate dirt over long periods of use, clean.

[0014] One aspect of the present disclosure provides an inner container for use in a pair of containers in which the inner container is detachable from a frame, the inner container having a camouflage portion that complements the recess of the mounting recess when the inner container is mounted on a frame having a mounting recess into which the inner container is attached. One aspect of the present disclosure is an inner container used in a pair of containers in which the inner container is detachable from a frame, wherein the inner container has a camouflage portion that complements the recess of the mounting recess when the inner container is attached to a frame having a mounting recess into which the inner container is attached. As a result, when the inner container is attached to the frame, the mounting recess formed in the frame is complemented by the camouflage portion formed in the inner container, making it appear as if there is no mounting recess, and resulting in a pair of containers with excellent integration between the inner container and the frame.

[0015] One aspect of the present disclosure provides a frame used in a pair of containers in which the inner container is detachable from the frame, the frame having a mounting recess into which the inner container is attached and detached, and a reinforcing projection protruding from the mounting recess, and the frame being able to strengthen the connection between the inner container, the frame, and the nozzle by tightening the reinforcing projection together with the neck of the inner container with a screw cap of a nozzle that discharges the contents from the inner container.

[0016] One aspect of the present disclosure is a frame used for a pair of containers in which an inner container is detachable from the frame. The frame has a mounting recess into which the inner container is detachably inserted and a reinforcing protrusion protruding from the mounting recess. By tightening the reinforcing protrusion together with the neck of the inner container with a screw cap of a nozzle for discharging the contents inside the inner container, the coupling state of the inner container, the frame, and the nozzle can be strengthened. Therefore, the coupling between the inner container and the frame can be strengthened by the reinforcing protrusion, and it is possible to prevent the inner container from being easily removed from the frame during use. Therefore, it is possible to provide a pair of containers that are excellent in terms of usability while being a pair of containers.

Advantages of the Invention

[0017] One aspect of the present disclosure may be a case where the inner container is a refill container or not, and the inner container can be removed from the frame. On the other hand, it is a pair of containers having excellent integrality between the inner container and the frame, or an inner container or a frame constituting the same. One aspect of the present disclosure is a pair of containers that may be regarded as a single container at first glance, or an inner container or a frame constituting the same. [[ID=IO]] One aspect of the present disclosure is a pair of containers having high safety at the attachment portion of the inner container when the inner container is attached to the frame, or an inner container or a frame constituting the same. One aspect of the present disclosure is a pair of containers having excellent design, or an inner container or a frame constituting the same.

[Figure 9] Figures 9A to 9E are schematic right side views of an inner container representing another aspect of the present disclosure. [Figure 10] Figures 10A and 10B are general left side views of a frame, representing another aspect of the present disclosure. [Figure 11] Figures 11A and 11B are central cross-sectional views of a frame in a front view, representing another aspect of the present disclosure. [Modes for carrying out the invention]

[0019] The pair containers of this disclosure will be described in more detail based on embodiments. Figure 1 shows a perspective view of the pair container 1 made of plastic containers in use, Figure 2 shows its front view, Figure 3 shows its left side view, and Figure 4 shows its top view. The pair container 1 shown in these figures consists of an inner container 10 that is roughly egg-shaped and a frame 20 that has a shape like a roughly elliptical ring with depth that is standing upright on its depth plane. The inner container 10 is housed inside the frame 20 and is used with the nozzle (dispenser) 2 attached to the inner container 10.

[0020] The pair container 1 may be considered to consist of at least an inner container 10 and a frame 20, or it may be considered to consist of these with a nozzle 2. This pair container 1 is used as a packaging container in which shampoo, conditioner, etc. are filled into the inner container 10. Next, we will explain the individual parts that make up the pair container 1.

[0021] <Frame 20>: First, let's describe the frame 20. Figure 5 is a perspective view of the frame 20, and Figure 6 is a plan view of the frame 20. The frame 20 has the function of supporting the inner container 10, which will be described later and cannot stand on its own, and is positioned to partially cover the outside of the inner container 10. The shape of the frame 20 shown in Figures 5 and 6 is just one embodiment; as long as it has a part that supports the inner container 10 and a base 25 that can be placed on a shampoo rack or the like, there is a great deal of freedom in the shape and design of the other parts, and it can be formed into any shape with excellent design.

[0022] The top portion 21 of the frame 20 has a roughly U-shaped mounting recess 22 into which the neck portion 11 of the inner container 10 is inserted. The outer peripheral edge of this mounting recess 22 has a support portion 23 that engages with the inner container 10 and supports the inner container 10. To describe the shape of the support portion 23 in more detail, a projection is formed along the wall surface 22a of the mounting recess 22, which protrudes outward from the wall surface 22a of the mounting recess 22. The groove 14b of the inner container 10 fits into this support portion 23, thereby supporting the inner container 10.

[0023] Furthermore, a reinforcing projection 24 is formed at the U-shaped central position 22b of the mounting recess 22, which strengthens the connection between the inner container 10 and the frame 20. This reinforcing projection 24 protrudes upward from the wall surface of the central part of the mounting recess 22. When the nozzle 2 is attached to the neck portion 11 of the inner container 10 after the inner container 10 has been fitted into the frame 20, the screw cap 2b of the nozzle 2 (see Figures 1 and 2) engages with this reinforcing projection 24 along with the neck portion 11 of the inner container 10, thereby fixing the nozzle 2 to the inner container 10 and simultaneously fixing the frame 20.

[0024] The reinforced projection 24 having these functions can have a shape in which a portion protrudes upward from the wall surface of the mounting recess 22, or a shape in which a portion further protrudes outward from the upwardly protruding portion. In the former case, the portion protruding upward can be held down by the screw cap 2b of the nozzle 2, and in the latter case, the portion protruding outward can be sandwiched between the threads of the screw cap 2b.

[0025] A bottom 25 is formed at the lower part of the frame 20, and a flat surface is formed thereon that allows the pair of containers 1 to be placed on a shampoo stand or shelf.

[0026] The shape of the frame 20 was described as being like a roughly elliptical ring with depth, standing upright on its depth surface. As shown in Figure 3, the frame 20 is shaped such that, when viewed from the side, the middle section 26 gradually narrows compared to the top 21 and bottom 25, so that the egg-shaped roundness of the inner container 10 is not hidden and is more visible when viewed from the side. Also, as shown in Figure 2, when viewed from the front, the frame 20 is shaped to enclose the outside of the egg-shaped inner container 10 with a predetermined gap, so that the suspended form of the inner container 10 is revealed.

[0027] The frame 20 is preferably made of a rigid resin such as polycarbonate, PET, polystyrene, polyethylene, or polypropylene. This is because it is easy to mold, lightweight, and has sufficient hardness to maintain the shape of the inner container 10 containing the contents. However, the material of the frame 20 is not limited to these resins, and other materials such as metal or ceramic can also be used.

[0028] <Inner container 10>: Next, we will describe the inner container 10. Figure 7 is a perspective view of the inner container 10, and Figure 8 is a plan view of the inner container 10.

[0029] The inner container 10 is the part that holds the contents such as shampoo, and together with the frame 20 it forms part of the pair container 1. Since the inner container 10 is detachable from the frame 20, it can be replaced with another inner container 10 filled with contents once its contents are consumed. In that sense, it can also be a refillable container. Alternatively, regardless of whether the contents are consumed, the container can be replaced with one of a different design, or an inner container containing shampoo, etc., can be replaced with one containing conditioner, etc., allowing for various ways of use as appropriate.

[0030] The main body 12 of the inner container 10, as shown in Figures 7 and 8, is egg-shaped, which is innovative and aesthetically pleasing. At the same time, it is highly practical because the nozzle 2 can suck up any remaining contents that tend to accumulate at the bottom of the main body 12 as the contents decrease during use. The neck portion 11 of the inner container 10 is the connection portion with the nozzle 2, and has a screw thread 11a for fixing the nozzle 2. In addition, a mounting portion 13 is formed at the base of the neck portion 11, that is, near the boundary with the main body portion 12.

[0031] The mounting portion 13 is a connecting portion for attaching the inner container 10 to the frame 20. The shape of the mounting portion 13 is not particularly limited, but the mounting portion 13 is shaped to conform to the mounting recess 22 of the frame 20, and the mounting portion 13 shown in Figure 8 is formed in a roughly rectangular shape in plan view. The mounting portion 13 has a groove 13b that engages with the support portion 23 of the frame 20, and plays a role in supporting the inner container 10 on the frame 20. The inner container 10 is incorporated into the frame 20 when the support portion 23 of the frame 20 is fitted into this groove 13b.

[0032] The camouflage portion 14 is the part that fills the cutout portion of the mounting recess 22 when the inner container 10 is fitted into the mounting recess 22 of the frame 20. In other words, referring to Figures 5 and 1, the outer frame line 27 that forms a smooth curve at the top 21 of the frame 20 is formed such that the outer frame line 14a of the camouflage portion 14 complements the cutout portion where the mounting recess 22 is formed, thus maintaining the smooth curve and ensuring the continuity of the outer shape.

[0033] Furthermore, since both the inner container 10 and the frame 20 can be handled and traded independently, the corners of the mounting recess 22 and the corners of the camouflage part 14 are chamfered to a minimum extent to prevent accidents. Therefore, as long as sharp corners are not created, the continuity of the container's outer shape may be impaired, and when considering the container as a whole, the camouflage part 14 complements the cutout portion created by the mounting recess 22, thus maintaining the continuity of the container's outer shape.

[0034] Furthermore, in Figure 7, the groove portion that engages with the support portion 23 of the frame 20 is not only the groove portion 13b located within the width of the neck portion 11, but also a groove portion 14b that communicates with the groove portion 13b is provided within the camouflage portion 14 that protrudes beyond the width of the neck portion 11. Therefore, it can be said that the groove 13b is extended by the length of the groove 14b provided in the camouflage part 14, and as a result, the area that engages with the support part 23 of the frame 20 is increased compared to the case where it engages with the frame 20 only around the neck part 11, so that the inner container 10 can be supported by the frame 20 more stably.

[0035] Having these camouflage parts 14 allows the inner container 10 to be fitted into the frame 20, filling the recessed area in the mounting recess 22. This enhances the integration of the inner container 10 and the frame 20, giving the impression of a single container overall, even though they are a pair of containers 1.

[0036] The inner container 10 can also be made of a rigid resin, but if it is to be used as a refill container, the main body 12 can be made of a thin, deformable film-like material, except for the neck portion 11 and the camouflage portion 14 which require strength. It can also be made of a transparent resin to indicate the remaining amount of contents.

[0037] <Nozzle (Dispenser) 2>: The nozzle 2 is a component that seals the opening of the neck portion 11 of the inner container 10 and also a component that discharges the contents inside the inner container 10. The nozzle 2 comprises a discharge portion 2a having a discharge port for the contents and a screw cap 2b that is attached to the inner container 10. The inner surface of the screw cap 2b has screw grooves (not shown) that screw into the screw threads 11 provided on the neck portion 11 of the inner container 10.

[0038] To use the pair container 1, remove the nozzle 2 from the inner container 10 to which it is attached, and fit the inner container 10 into the mounting recess 22 of the frame 20. Then, reattach the nozzle 2 to the inner container 10. At this point, the inner container 10 and the frame 20 are joined not only by the engagement of their respective engagement parts, but also because the nozzle 2 connects the neck portion 11 of the inner container 10 to the reinforcing projection 24 of the frame 20, so that the nozzle 2, inner container 10, and frame 20 are all sufficiently joined and become one unit. Therefore, even though it has an inner container 10 and a frame 20, it can be used as a single container as a whole.

[0039] A typical form of the inner container 10 and frame 20 has been described, but its size and shape are not particularly limited. As long as the neck portion 11 fits into the mounting recess 22, the grooves 31b and 14b engage with the support portion 23, the inner container 10 is assembled to the frame 20, and the bottom 25 of the frame 20 can stand upright stably when placed on the floor or the like in that state, it is acceptable.

[0040] Figure 9 shows inner containers 10a to 10e with different external shapes. Figure 10 also shows frame types 20a and 20b with different external shapes. Furthermore, Figure 11 shows frame types 20c and 20d with different external shapes. The external shapes shown in these figures are just examples of inner containers 10 and frame types 20.

[0041] Although preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments described above, and various modifications and changes are possible within the scope of the gist of the present invention as described in the claims.
