Description

[Detailed Description of the Invention] The present invention relates to a container with a sliding member, and more specifically, a sliding member consisting of an outer case that houses a plate-shaped lid or a drawer-shaped container engages with a box-shaped or drawer-shaped container body. This invention relates to a set of structures made of molded hard foamed resin that can be moved and installed tightly.

Box-like or drawer-like containers that are assembled by engaging and sliding a sliding member consisting of an outer case that houses a lid or a drawer-like container include, for example, fishing bait boxes, chopstick boxes, etc. The container is made of a relatively rigid material such as wood, pressed sheet metal, or injection molded synthetic resin. When sliding a slide member like the one described above in such a container, it is preferable that the friction is small, and it is desirable that the slide member has enough friction to prevent it from opening accidentally, but it is preferable that the precision of the engaging part be adjusted during manufacturing. It is difficult to fit within tolerances that maintain friction.

The present invention was devised in view of the above-mentioned difficulties, and its purpose is to provide a container with a simple structure in which the slide member is easy to slide and the slide member is difficult to loosen when the slide member is closed. Another object of the present invention is to provide a container that can be tightly attached to the container body without causing the slide member to loosen even if the tolerance between the engaging portion of the slide member and the container body is large.

The present invention includes a sliding member that is a plate-shaped lid or an outer case for allowing a box-shaped container to be taken in and out in a drawer type, and a sliding member that has a portion that slides by engaging with a portion of the lid or the outer case. and a container body that is covered with the lid or stored in the outer case, and the slide member and the container body are molded of the same or different types of hard foam resin, and the slide member and/or the container body are This is a container with a sliding member characterized in that the engaging sliding portion has a portion that is slightly thinner or larger in dimension and presses against each other to increase friction and produce an anti-slip effect.

A set of containers of the present invention uses hard foamed resin and can absorb variations in tolerance through the elasticity of the material. In the container of the present invention, engagement means that the container has become fitted, and this part is slid in and out of each other, but a part of this sliding surface is dimensionally slightly reduced. By making it thinner or thicker, a large frictional force is generated between the slide member and the container body in the closed state of the slide member.

The container of the present invention can be suitably used as a container for storing and transporting frozen desserts, fresh foods, serums, medicines, etc., as a one-way container, and can be used as a general heat-insulating container.

Containers of the present invention may have lids, such as those with the lid on the top or the lid on the side, but in order to prevent leakage and condensed water from spilling due to contents spilling, it is necessary to have a top lid. is preferred.
Among the containers of the present invention, it is preferable that the outer case housing the container main body has a mouth-shaped cross-sectional shape for a container that can be put in and taken out in a drawer type, since this can increase rigidity than a container that has a square-shaped cross-sectional shape.

The sliding member and the container main body of the present invention have a fitting part where they can slide on each other is a fitting between a protrusion and a recessed groove, but the sliding is on the side surfaces on both sides of the sliding member (in the case of a sliding lid), or A part of the side surface, a part of the upper part and/or the lower part of the side part is rectangular, trapezoidal, inverted trapezoid (dovetail shape), semicircular, semielliptical,
Examples include a combination in which a single protrusion such as a triangle or an inverted triangle is provided, and a groove shaped to fit the protrusion is provided at a corresponding position on the container body, and the shape of the protrusion and the groove and/or Regarding the position, it is also possible that the slide member and the container body are interchanged with each other.

Examples of protrusions and grooves will be explained with reference to the drawings. In Fig. 1, 1 is the slide member that is the lid, 2 is the container body, 3 is the ridge provided at the upper end of the lid, and 4 is the upper part of the container. This is a groove provided on both sides.

In FIG. 2, 5 is a lid, 6 is a container, 7 is a groove provided near both ends of the top of the lid, and 8 is an example of a protrusion provided on both ends of the top of the container.

FIG. 3 is a perspective view of what is shown in FIG.

FIG. 4 is a perspective view of the box-shaped container 10 and the outer case 9 through which the box-shaped container 10 is taken in and taken out. Reference numeral 11 denotes a convex strip 12 on both edges of the upper part of the container, indicating a groove provided at the inner upper end of the outer case.

In this invention, due to the rigidity and elasticity of the hard foam resin made of hard polyurethane resin, polystyrene resin, cross-linked polyethylene resin, etc., the opening and closing of the sliding member during use is not extremely hard over the entire length of the sliding part, and is smooth without rattling. It has the feature that tolerances that occur during manufacturing do not need to be strictly controlled.

In the present invention, the deformation resistance of the sliding member and/or the engaging portion of the container body can be increased in order to accurately open and close the sliding member and to prevent the sliding member from slipping. That is, by setting the foaming ratio of the sliding part of the slide member and/or the container body to be lower than that of other parts, the strength of the engaging part is increased and the feel when opening and closing the slide member is improved.
When the container with a slide member of the present invention is used repeatedly, the engagement is less likely to deteriorate.

When manufacturing the container with a sliding member of the present invention, a recessed sliding member can be manufactured using a mold component that can be slid and/or contracted in a foam mold. The sliding part of the sliding member and/or the container body of the container with a sliding member of the present invention can be molded integrally, or alternatively, the sliding part can be manufactured separately and then bonded together. As another method, a method may be used in which the portion of the mold corresponding to the sliding portion is suctioned through a ventilation hole to selectively arrange the unfoamed low expansion ratio resin material.

When a plate-shaped slide member is used as the slide member of the present invention, foam molding can be performed particularly easily if the slide member is divided into two parts, for example, so that the slide members slide facing each other. This also reduces the cost of mold production.

In order to prevent the slide member of the container with a slide member of the present invention from loosening or coming off, the container can be sealed with an adhesive tape, an adhesive tape, or an adhesive label.

The structure of the present invention has the following structure so that the slide member can be easily slid and the slide member is difficult to loosen when the slide member is closed. In the present invention, the cross section of a part or the whole of the engaging sliding portion of the slide member and/or the container body is gradually tapered at the tip or thickened at the rear, thereby increasing the contact friction between the slide member and the container body. Therefore, an anti-slip effect can be produced.

Figures 7 to 12 show part 1 that produces an anti-slip effect.
FIG. 2 is a partially enlarged perspective view of the convex portion of the lid having the shape shown in FIG. 1, showing an example of the shape of No. 3; FIGS. 7 and 8 show an example in which the tip portion is tapered as a part of the convex portion 3. FIG. 9, 10, and 11 show examples in which a wedge-shaped small protrusion 13 with a tapered tip is provided on the side of the convex portion 3. FIG.

Thus, in the structure of the present invention, when opening and closing the slide member, it is possible to give a tight feeling due to the tapered or thickened sliding portion. More preferable results can be obtained by providing it in a part of the moving part. For example, by providing a tapered portion with a tapered section and/or a protruding portion on the side surface of the protruding strip at the tip of the slide member, and at the same time providing a tapered portion in the corresponding groove portion at the tip of the container body, the slide member may be The slide member can be advantageously attached to the container body in the latter half of the sliding operation. The tapered portion can be provided at any position among the tip, front side, and intermediate position of the slide member and/or the container body, and can be provided at any position above, on the side, or below the sliding portion of the slide member and/or the container body. It can be installed at any position inside the house.

For example, the end portion (i.e., part a, d) or the cross section of the groove becomes smaller over the entire length, or the protrusion 3 of the lid
For example, the cut-off ends (i.e., a', b', c', d' and By deforming the portion shown in the figure so that the convex portion becomes larger, an anti-slip effect can be produced.
