Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple food container made of synthetic resin and having a housing for chopsticks such as chopsticks, a simple fork made of synthetic resin, and knives.

0002

[Prior Art] In recent years, such simple containers for food storage have been developed, consisting of a container body made of a thin sheet of dense synthetic resin whose frame and bottom are integrally molded, and a lid made of a thin sheet of dense synthetic resin. For example, as disclosed in Japanese Utility Model Publication No. 11888/1988, a container body made of dense synthetic resin is used, as is the case with a container body in which a bottom plate made of a thin dense synthetic resin plate is bonded to the lower end surface of a frame material made of foamed synthetic resin. Containers with lids made of thin plates are used. When selling food using such containers, chopsticks are fixed to the outside of the container with tape, etc., or a groove-like recess is formed in the lid of the container, the chopsticks are stored in this recess, and the chopsticks are secured with rubber rings. and handed it to the customer.

However, this way of attaching chopsticks is
Not only is it time-consuming for the seller, but it is also inconvenient for the user, and it is difficult to get rid of its low-class appearance.

[0004] Therefore, the applicant of the present application filed Utility Application No. 2-569.
In the specification of Application No. 11 and Utility Model Application No. 3-4292, a structure that can store and fix chopsticks in the frame material, lid, or bottom plate is formed in advance, so that the provider can omit the step of fixing the chopsticks to the container. We proposed a simple food container.

[0005]

[Problem to be solved by the invention] However, in both cases, although there is an advantage in terms of streamlining the process of attaching chopsticks after food is stored in a container, the chopstick storage section has a special structure. There is room for improvement, such as requiring time and effort during the container manufacturing process, making it inconvenient for users to take out the chopsticks, and creating a sense of discomfort during packaging.

[0006] The problem to be solved by the present invention is to solve the problem of attaching and using chopsticks, which is essential for such a simple food container, in the entire process of container manufacturing, food storage, packaging, and furthermore, use by users. .

[0007]

[Means for Solving the Problems] The present invention provides a simple food container made of synthetic resin, which comprises a container body whose bottom portion is made of a dense synthetic resin thin plate and a lid made of a dense synthetic resin thin plate. A feature is that a plurality of protrusions for locking chopsticks are formed on the bottom surface of the main body or the outer surface of the lid.

[0008] When a container body is used as the container body, the frame body is formed of a band-shaped body made of foamed synthetic resin, and a bottom plate made of a dense synthetic resin thin plate is fused to the end face of the frame body. A protrusion for locking chopsticks is formed on the outer surface of the bottom plate.

[0009] Furthermore, when using a container body made of a thin sheet of dense synthetic resin in which the frame portion and the bottom portion are integrally molded as the container body, chopsticks may be secured to the outer surface of the bottom portion of the container body. Form multiple protrusions for

[0010] As the part for locking the chopsticks, the flat part of the bottom surface of the container body, the recessed part on the back side of the partition formed in the bottom part, or furthermore, the top surface of the lid can be used.

[0011] Furthermore, when the chopsticks are stored in a paper bag or a resin sheet bag, the protrusions for locking the chopsticks should be slightly wider than the width of the chopstick bag so that the protrusions can hold the chopstick bag at multiple points. They are arranged in two rows with narrow intervals.

[0012]Although the locking protrusion can be of any shape, the important point is that the chopsticks can be pushed in and stopped easily, and furthermore, when the chopsticks are used, they can be easily removed from the stop. Any shape may be used as long as it can do so.

[0013]

[Function] The structure of the simple food container consists of simply arranging a plurality of protrusions on the bottom or lid made of a dense synthetic resin thin plate of the container body that makes up the container body. It can be molded without any special care, has no effect on the packing or packaging of food, can set and secure chopsticks without using any accessory equipment, and has no influence on the form of chopsticks. The user can easily remove it from the set state.

[0014]

[Example] The attached figures show examples of the present invention. The first example shows an example in which the present invention is applied to the outer surface of a lid, and the second and third examples show examples in which the present invention is applied to the outer surface of a lid. An example in which the present invention is applied to the back surface of a partition convex portion formed at the bottom of the main body is shown.

Example 1 In FIG. 1, a simple container consists of a container body 1 and a lid 2, and the container body 1 is a strip made of styrofoam with a thickness of approximately 3 to 5 mm (5 mm in this example). A thickness of about 0.2 to 0.5
The bottom plate 4 is made by vacuum forming a polystyrene sheet with a thickness of about 0.2 to 0.35 mm (in this example, 0.4 mm) and is bonded by heat fusion. .2mm) O. P. S. This is a sheet that is pressure-formed. In addition, the knob designated by the reference numeral 5 in the figure is a knob integrally formed on the lower edge of the lid 2 for convenient removal of the lid 2 from the container body 1. Reference numeral 6 indicates a chopstick setting location formed on the surface of the lid 2. This setting point 6 is shown in Figure 2.
It has a shallow recess with a length and width sufficient to accommodate the chopstick bag shown in the figure, and a protrusion 7 is formed on the edge of the recess for locking the side of the chopstick bag H to be stored therein. A plurality of the locking protrusions 7 are arranged on both sides of the recess at intervals narrower than the width w of the chopstick bag H, either facing each other or alternately in a staggered manner.
In this embodiment, two are arranged on each side facing each other.
The shape of the locking protrusion 7 is shown in FIG. 2, which shows a cross section taken along line A--A in FIG. Chopstick bag H is placed in the setting point 6 of this chopstick.
By just slightly pressing both edges of the chopstick bag H and setting it, the locking protrusion 7 will lock the upper surface of both edges of the chopstick bag H, as shown by the broken line in Figure 2, and the chopstick bag can be easily taken out when in use. It can be set up easily.

The locking protrusion 7 shown in FIGS. 1 and 2 can also be formed directly on the surface of the lid 2 without forming a recess as the setting location 6.

Further, in the same embodiment, ordinary disposable chopsticks stored in a paper bag are explained as an example, but the chopsticks themselves, as well as simple spoons and forks made of synthetic resin, also have the locking protrusion 7. It can be attached in the same way by adjusting the number or the location of formation.

Furthermore, in FIGS. 1 and 2, the chopstick attachment structure has been explained using an example in which it is provided on the lid 2, but the structure can also be applied to the back surface of the bottom plate 4 of the container body 1 shown in FIG. can.
