Description

  The present invention relates to a container having a handle attached to a recess provided in a body part of a container body made of a synthetic resin.

Conventionally, containers having a handle on the body of a synthetic resin container body are known in various shapes, structures, and materials, and are fixed by attaching the handle to a recess provided on the body of the container body. Is also known (see, for example, Patent Documents 1 and 2).
The handle fixing means ensures that the weight of the contents can withstand, and the handle is fitted and fixed to the container body in consideration of weight reduction and cost reduction of the container body. Depending on the material, size, type of contents, weight, etc. of the container body and handle, such as insert molding of the handle during manufacture of the container body, winding the handle around the container body, or combining these The form is known.
In particular, in a large-capacity container as described in Patent Document 2, the weight of the contents is very heavy, and thus it is necessary to have a structure that can withstand the weight while firmly fixing the handle and the container body.

However, when a large-capacity large container is filled and sealed, even if the container body and the handle are fixed, the container body and the handle itself will not be deformed when the handle is lifted or tilted. Unavoidable.
In particular, in a large container of 5 liters or more, weight reduction is performed by thin molding. In recent years, a container body made of a polyester resin or the like has been used as an alternative to the polycarbonate resin often used for large container bodies for water servers.
However, when such a weight reduction or an alternative material is used, the physical properties of the material are softer than that of the polycarbonate resin, the strength such as bending is lowered, and the deformation of the container body is increased.
And there also existed a problem that a fitting will become weak by deformation | transformation of a container main body or a handle, and a handle will remove | deviate.
Furthermore, when the handle is fitted and fixed by fitting or bonding to a container body having a recess provided in the body, or when the container is filled and sealed with a handle, the container is lifted and tilted. Due to the deformation of the main body and the handle, a slight gap may occur between the container body and the handle. If this gap occurs near the handle part of the handle, fingers or clothing may get caught in the gap, resulting in an accident or injury. There was a risk of inviting.

In order to prevent such a gap from occurring, the handle is firmly fixed as a fitting structure that fits into the concave portion of the body portion of the container body, or all the attachment portions (contact portions) of the handle are attached to the container body. It is conceivable to adhere to the concave portion of the trunk portion.
However, when the above-described fitting structure is adopted, there is a problem that special molding of the container main body and the handle is required, and the number of man-hours for fitting work is increased, resulting in an increase in manufacturing cost.
In addition, as described above, there is a problem that the handle comes off.
Furthermore, when bonding all of the handle attachment parts, it is necessary to widen the application range of the adhesive, and at that time, supplying the adhesive to uniformly apply the adhesive toward all surfaces of the handle attachment part There is a problem that the coating process becomes complicated, man-hours increase, and the manufacturing cost increases.

  The present invention solves the above-described problems, simplifies the structure of the container body and the handle, facilitates assembly, reduces the number of manufacturing steps, and allows fingers and clothing to be sandwiched in gaps generated by deformation. It aims at providing the container made from a synthetic resin to prevent.

Even if there is a gap between the first wall surface and the first wall surface abutting portion of the recess or the second wall surface and the second wall surface abutting portion of the recess due to the deformation of the handle, the protective protrusions are at both ends of the handle portion. It is possible to prevent fingers and clothing from being caught in the gaps and prevent accidents and injuries.
In addition, because the handle when the handle is lifted or tilted and the bending moment generated in the handle due to the change in load balance is received by the protective protrusion of the handle, deformation of the container body and handle can be reduced. It is also possible to reduce the gap generated by.
Furthermore, there is no need to provide a fitting structure between the concave portion of the container body and the handle, or to apply an adhesive to a portion other than the bottom adhesive portion of the handle, thereby simplifying the structure of the container body and the handle. As a result, assembly is facilitated and the number of manufacturing steps can be reduced.
