  As a container with a lid, a container with a lid in which a lid body connected to a container body having a large opening portion by a hinge having a flexible packing body made of an elastic elastomer is screwed together to provide a sealing property to the opening portion. Has been proposed. (For example, see Patent Document 1)

Japanese Patent Laid-Open No. 10-157762

  The container has a mouthpiece piece on the inner peripheral edge of the annular plate portion made of an elastic elastomer between the upper end surface of the cylindrical mouth and neck portion of the container body and the top wall of the assembly body which is connected to the lid body so as to be opened and closed. The assembly body is sandwiched, the assembly is screwed into the mouth and neck of the container body to form a sealed container, and the upper edge periphery of the mouthpiece piece is brought into close contact with the inner surface of the lid body It is trying to seal.

  The present invention proposes a container with a lid having sufficient impact resistance that can protect a stored item in response to dropping of the container by using a flexible and elastic material made of elastomer together with a thermoplastic resin. . In addition, we propose a container with a lid that has sufficient hermeticity, mounting stability, and ease of handling.

  The container with a lid of the present invention includes a container body, an inner dish, and a cap.

  The container body is made of a thermoplastic resin skeleton with an elastic part made of a flexible and elastic material and formed into a dish shape. The container body is made of a flexible and elastic material from the top of the bottom wall. The supporting protrusions are erected, and the locking protrusions made of a flexible and elastic material are erected from the top surface of the peripheral wall.

  The skeleton portion is provided for the purpose of imparting rigidity to the container body and imparting shape retention, and is provided for the purpose of being able to lock the cap firmly and stably. Therefore, basically, it is preferable to provide a bottom wall constituent part and a peripheral wall constituent part, and to provide a gap part filled with an elastic part between the bottom wall constituent part and the peripheral wall constituent part. As the thermoplastic resin forming the skeleton, polyethylene, polypropylene, and the like shown in this type of container can be preferably used, but not limited to this, other thermoplastic resins can naturally be used.

  The elastic part is provided to increase the frictional force at the bottom of the container body to improve the placement stability, to prevent the hand from slipping during handling, or to form the support protrusion and locking protrusion integrally. In order to stably integrate with the skeleton part, a form in which the skeleton part is integrally formed on both the inner and outer side parts of the skeleton part via a gap is preferable. Further, as one specific preferred form, the upper surface of the peripheral wall is covered from the upper surface of the bottom wall through the inner peripheral surface of the peripheral wall so that the support protrusion and the locking protrusion can be integrally projected. If the lower part of the peripheral wall is configured in consideration of the mounting stability and the anti-slip of the hand, and these are integrally formed, there is an advantage that the above effects can be exhibited together. The flexible and elastic material generally refers to an elastomer which is a highly elastic polymer material such as rubber, and can be appropriately selected and used regardless of whether it is a thermoplastic type or a crosslinked type. Specifically, silicone rubber can be preferably used, but is not limited to this.

  The support protrusion is for supporting the inner plate so that a gap is formed between the inner plate and the bottom wall in an upwardly biased state. Therefore, its shape can be elastically deformed and can support the inner plate bottom substantially horizontally. As long as it is variously adopted, for example, it may have a cylindrical shape capable of elastic deformation, or may have a configuration in which support projecting pieces capable of elastic deformation are dispersedly provided on the bottom wall. As a preferable example, a plurality of support protrusions in the form of conical protrusions are arranged in a ring shape.

  The locking protrusions are for locking the upper end of the outer periphery of the intermediate plate biased upward by the support protrusions to prevent the intermediate plate from being pulled out. It is constructed so that it can be surely prevented from being pulled out after the inner tray is mounted, and various specific shapes can be adopted. For example, the thing of the form standing upright from the container body top surface in the shape of a cylinder may be sufficient, and the thing of the form of standing up at intervals of the circumferential direction may be sufficient. As the locking means, a locking projection may be provided on the inner surface, or the upper end of the locking projection may be bent inward. The container body can be formed by insert molding, for example.

  The middle dish is made of thermoplastic resin, metal, etc., and has a shape of a bottomed dish with an upper end opening with a peripheral wall portion standing from the periphery of the bottom wall portion, and is outward from the upper end of the peripheral wall portion. An extension of the flange can be preferably used. In addition, the peripheral wall portion is formed in a size that creates a gap with the inner surface of the peripheral wall of the container body, so that the impact on the container body is not directly transmitted to the inner pan. Examples of what is stored in the inner dish include cosmetics and medicines.

  The cap is made of a thermoplastic resin, and is provided so as to be detachable by extending a top plate from the upper end of the mounting cylinder fitted to the outer peripheral wall of the container body. As the cap locking means, screwing locking means is preferable, but other locking means may be used. Moreover, favorable airtightness can be achieved by suspending a seal cylinder from the back surface of the top plate of the cap and press-contacting the inner layer portion at the upper end of the peripheral wall. In that case, when combined with the screw locking means, there is an advantage that good airtightness can be maintained for a long time even in long-term use.
