Abstract
Description
[Technical Field]
[0001] The present invention relates to a packaging container, and more particularly to a packaging technology for packaging small items such as sweets for gifting. [Background technology]
[0002] In the past, for example, at a wedding reception, a bride would give small items such as sweets to friends attending the reception in packaging containers, and in this case, paper or plastic containers have generally been used as packaging containers.
[0003] Recently, there has been a trend to replace paper or plastic packaging containers with metal ones in order to give such gift packaging containers a sense of weight and luxury, as well as durability.
[0004] To the best of the applicant's knowledge, there are no patent documents disclosing these conventional metal packaging containers. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] none Summary of the Invention [Problem to be solved by the invention]
[0006] However, in conventional metal packaging containers, the container body that contains small items and the lid that closes the container body are structured so that they can be opened and closed. However, because the container body and the lid are made of metal in this type of fitting structure, it is difficult to accurately adjust the relative dimensions of the fitting parts between the two during manufacturing, making it difficult to achieve a smooth and stable fitting and use state, as well as an open and closed use state. This makes it difficult to achieve the original goal of giving the container a sense of weight and luxury, and further improvements were required.
[0007] The present invention was made in consideration of the above-mentioned problems of the prior art, and its purpose is to provide a packaging container with a structure that allows smooth and stable opening and closing of the metal container body and lid. [Means for solving the problem]
[0008] In order to achieve the above-mentioned object, the packaging container of the present invention is for storing small items such as sweets, and comprises a metal container body for accommodating the small items, a metal lid body for closing the container body, and a plastic connecting frame member for integrally joining the container body and the lid body so that they can be opened and closed. The connecting frame member is characterized by having a body fitting portion that fits inside the upper opening of the container body, a lid fitting portion that fits removably inside the lower opening of the lid body, and an engaging step portion provided at the boundary between these fitting portions and that abuts and engages with the upper opening of the container body and the lower opening of the lid body.
[0009] In a preferred embodiment, the container body and the lid body have an external shape in a state where they are integrally joined by the connecting frame member, in the form of a three-dimensional heart. [Effects of the Invention]
[0010] The packaging container of the present invention consists of a metal container body for storing small items and a metal lid body that closes the container body, and a plastic connecting frame member that integrally connects the container body and lid body so that they can be opened and closed. The connecting frame member has a body fitting portion that fits inside the upper opening of the container body, a lid fitting portion that fits removably inside the lower opening of the lid body, and an engaging step portion provided at the boundary between these fitting portions that abuts and engages with the upper opening of the container body and the lower opening of the lid body. Therefore, a packaging container can be provided that allows the metal container body and lid body to be opened and closed smoothly and stably.
[0011] That is, the container body and lid are integrally joined by a plastic connecting frame member that allows the metal container body and lid to be opened and closed. The connecting frame member has a body fitting portion that fits inside the upper opening of the container body, a lid fitting portion that removably fits inside the lower opening of the lid, and an engaging step portion that is provided at the boundary between these fitting portions and abuts and engages with the upper opening of the container body and the lower opening of the lid. Therefore, the metal container body and lid are not directly fitted and connected, but are indirectly fitted and connected via the elastic plastic connecting frame member. As a result, the container body and lid can be opened and closed smoothly and stably, while retaining the heavy and luxurious feel that is unique to metal packaging containers.

DETAILED DESCRIPTION OF THE INVENTION
[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which like reference numerals denote like components or elements throughout the drawings.
[0014] The packaging container of the present invention is shown in Figures 1 to 6. Specifically, this packaging container 1 is used to hold small items such as sweets to be given as gifts to friends attending a wedding reception, and has an exterior shape in the form of a three-dimensional heart with diamond cuts 14.
[0015] As shown in FIG. 4, the packaging container 1 comprises, as its main parts, a metal container body 2, a metal lid 3, and a plastic connecting frame member 4 that joins these together so that they can be opened and closed.
[0016] The container body 2 is made of a metal plate with a shape and dimensions suitable for containing small items such as sweets, and the metal material used is preferably zinc-plated iron (galvanized iron) or tin-plated iron (tinplate), and in the illustrated embodiment, zinc-plated iron is used.
[0017] As shown in the figure, the external shape of the container body 2 is such that the outer peripheral planar contour shape is formed in a substantially heart shape (Fig. 3), and the outer peripheral surface is formed into a three-dimensional shape with diamond cuts 14. Specifically, the outer peripheral planar contour shape is formed in an angular heart shape (Fig. 3) corresponding to the shape of the diamond cuts 14 on the outer peripheral surface of this container body 2.
[0018] As shown in Figures 2 and 4, the upper opening 5 of the container body 2 extends slightly in the mating direction as a mating portion with the lid body 3, and its inner surface 5a is a mating surface with an angular heart-shaped outline.
[0019] The lid 3 is made of a metal plate that closes the container body 2, and specifically, the lid 3 in the illustrated embodiment is made of exactly the same material as the container body 2. Therefore, a description of this lid 3 will be omitted.
[0020] The connecting frame member 4 is made of plastic and integrally joins the container body 2 and the lid body 3 so that they can be opened and closed. In the illustrated embodiment, the connecting frame member 4 is made of transparent plastic.
[0021] As shown in Figures 4 and 5, the connecting frame member 4 is an integrally molded product in which a main body fitting portion 6, a lid fitting portion 7, and an engaging step portion 8 provided at the boundary between these two portions 6, 7 are integrally formed.
[0022] The main body fitting portion 6 is a portion that fits into the inside of the upper end opening 5 of the container main body 2, and as shown in Figure 4, has an outer surface 6a with an angular heart-shaped outline that corresponds to the inner surface 5a of the upper end opening 5.
[0023] In connection with this, the outer surface 6a of the main body fitting portion 6 is provided with a plurality of engaging protrusions 9, 9, ... (six in the illustrated embodiment), ensuring a predetermined fitted and fixed state with the upper end opening 5 of the container main body 2.
[0024] The lid fitting portion 7 is a portion that removably fits inside the lower end opening 10 of the lid 3, and as shown in Figure 4, has an outer surface 7a with an angular heart-shaped outline that corresponds to the inner surface 10a of the lower end opening 10.
[0025] In connection with this, the outer surface 7a of the lid fitting portion 7 is provided with a plurality of engaging protrusions 11, 11, ... (three in the illustrated embodiment), ensuring smooth and stable opening and closing of the lower end opening 10 of the lid 3.
[0026] The engagement step 8 is provided at the boundary between the main body fitting portion 6 and the lid fitting portion 7, and is structured to abut and engage with the upper end opening 5 of the container main body 2 and the lower end opening 10 of the lid 3.
[0027] Furthermore, when the engaging step 8, the upper opening 5 of the container body 2, and the lower opening 10 of the lid 3 are in abutting engagement, their outer surfaces 8a, 5b, and 10a are configured to be flush (see Figure 2).
[0028] The external shape of the container body 2 and the lid body 3 when they are integrally joined by the connecting frame member 4 is a three-dimensional heart shape with diamond cuts 14, 14 applied thereto.
[0029] The packaging container 1 configured as described above is given to attendees such as friends as a gift with any small item such as sweets placed inside the container body 2 at a celebration such as a wedding reception.
[0030] In this way, an attendee who receives the packaging container 1 as a gift can use it for personal use as a packaging container for any small item even after removing the small items from the packaging container 1 and emptying it.
[0031] As described above in detail, the packaging container 1 of this embodiment includes a plastic connecting frame member 4 that integrally connects the metal container body 2 and lid body 3 so that they can be opened and closed, and this connecting frame member 4 includes a body fitting portion 6 that fits inside the upper opening 5 of the container body 2, a lid fitting portion 7 that detachably fits inside the lower opening 10 of the lid body 3, and an engaging step portion 8 that is provided at the boundary between these fitting portions 6, 7 and that abuts and engages with the upper opening 5 of the container body 2 and the lower opening 10 of the lid body 3. Therefore, the metal container body 2 and the lid body 3 are not directly fitted and connected, but are indirectly fitted and connected via the elastic plastic connecting frame member 4. This allows the container body 2 and the lid body 3 to be opened and closed smoothly and stably while retaining the heavy and luxurious feel that is inherent to the metal packaging container 1.
[0032] Furthermore, the packaging container 1 of this embodiment can be handled by carrying it directly with the fingers, and can also be used by attaching a strap 15 as shown in FIG. 6, if necessary.
[0033] Specifically, the attachment end 15a of the strap 15 can be fixedly supported in a clamped state between the container body 2 and the connecting frame member 4, which allows the packaging container 1 to be handled not only by holding it directly with the fingers, but also by holding the strap 15 with the fingers.
[0034] The above-described embodiment merely shows a preferred embodiment of the present invention, and the present invention is not limited to this embodiment, and various design modifications are possible within the scope of the present invention. [Explanation of symbols]
