Description

  The present invention relates to a garbage container that can be detachably attached to a kitchen.

  2. Description of the Related Art Conventionally, kitchen garbage containers are generally used in which a garbage bag is attached to a plastic or metal so-called triangle corner. However, such a triangular corner is not preferable from the viewpoint of appearance and hygiene because it itself becomes dirty or slimy.

As an alternative to the triangular corner, Patent Document 1 discloses an input container for garbage, articles, etc., which is a combination of a bag support frame and a bag having a constricted portion. This charging container is used with the bag support frame fixed on the sink, and is attached so that the bag into which the garbage has been placed is located in the sink, and only the bag is removed and discarded. It is excellent in that the appearance and hygiene problems are solved. Such an input container is commercially available from the applicant of the present application under the trade name “No Triangular Corner”.
Japanese Patent Publication No. 5-20321

The method of attaching the bag to the bag support frame is widely known as a method of using the product name `` triangular corner not '', and as a method of using the product, the following procedure (1) to ( 6) and corresponding photos are printed. Here, the “ring” corresponds to the bag support frame of the present invention.
(1) Take out one bag and put the ring into the bag.
(2) Hold the bag around the base of the ring with your left hand and lift the bottom of the bag up with your right hand.
(3) Lift the bottom of the bag until it is a little pin.
(4) While holding the bag with your left hand, put the bottom of the picked up bag into the ring.
(5) Push down gently until the bag catches.
(6) The bag is shaped and completed.

  It is an object of the present invention to provide a trash container having an increased bag mounting strength without impairing the bag mounting capability of the bag supporting means to the bag supporting frame.

As a means for solving the problems, the present invention
A trash container having a bag support frame, a bag support means having an attachment to a fixed surface connected to the bag support frame, and a bag to be attached to the bag support frame;
The bag has two stopper portions in which the opposing surfaces at both ends of the opening are fixed and integrated.
The inner peripheral length (L ₁ ) of the opening inside the stopper and the outer peripheral length (L ₂ ) of the bag support frame are expressed by the following equation (1): L ₁ / L ₂ <1 (1) Provide a garbage container that is set to satisfy the relationship.

  The garbage container of the present invention can be used by attaching a bag to the bag support frame of the bag support means as described in the above procedures (1) to (6). The stopper portion in the bag of the present invention acts to prevent the bag from dropping off by hooking the bag on the bag support frame in step (5).

  Further, by providing such a stopper portion on the bag and associating the bag support frame with the bag having the stopper portion so as to satisfy the formula (1), the ease of attachment when attaching the bag to the bag support frame is improved. At the same time, the attachment strength of the bag is increased.

  If the bag attachment strength to the bag support frame is low, the attachment part may come off when the bag is attached, and garbage will contain a lot of moisture and its mass will increase, so the bag will be removed from the bag support frame before discarding the bag. Although there is a possibility of dropping off, the present invention solves the above problem by further increasing the attachment strength to the bag support frame.

  As the bag support frame, a circular or elliptical one made of synthetic resin, metal, wood or the like (for example, one used in the above-mentioned commercial products) can be used. The bag preferably has a large number of small holes for draining on the bottom side. A bag made of a thermoplastic resin can be used. The stopper portion of the bag is formed by applying a method of heat-sealing opposing surfaces of a thermoplastic resin bag, a method of bonding with an adhesive, or the like.

In the present invention, in the above formula (1), by setting the range of L ₁ / L ₂ = 0.50 to 0.99, it is possible to further enhance the ease of attachment and the attachment strength of the bag.

In the present invention, the stopper portion formed on the bag is
(I) The stopper part is composed of a curve or a combination of a straight line and a curve (II) The stopper part is a curve surrounding the side of the bag,
(III) The stopper portion is a ring whose outer periphery includes a curve,
(IV) The stopper portion is a surface whose outer periphery includes a curve (or an assembly of points equal to the surface),
(V) A combination of (II) to (IV) as appropriate,
Can be.

  As shown in FIG. 6, when the stopper portion (that is, the fixed and integrated portion) 201 is a straight line, when the bag is attached to the bag support frame, the force applied by opening the bag opening 212 is linear. There is a risk that the fixed and integrated part may be peeled off or the bag may be damaged at the fixed and integrated part.

  However, in the case of having a curve as in the stopper portion of the present invention, the force is dispersed and does not concentrate in one place, so that there is no adverse effect on the fixed and integrated portion.

  In the case of the stopper part (I), in order to solve the problem of the comparative example shown in FIG. 6, the part facing the opening part direction of the bag may be a curve. By doing in this way, since the force applied to the edge part of a stopper part is spread when the opening part of a bag is expanded, the attachment property to a bag support frame becomes good.

  In the case of the stopper portions (II) and (III), for example, a linear heat-sealed portion and an air layer surrounded by the heat-fused portion (swelled) may be used, or the air It may be one that does not have a layer (one that does not swell) (hereinafter referred to as “non-air layer”).

  In the case of the stopper part (IV), for example, a circular, elliptical or fan-shaped heat fusion part can be formed. In this way, when the stopper portion is a surface, the fixing strength between the opposing surfaces of the bag made of thermoplastic resin is increased compared to the case where the stopper portion is a line, so that the attachment property to the bag support frame is improved.

  In the case of the stopper portion (V), a heat-sealing portion of a surface or a point can be formed on the inner side of the curve surrounding the side of the bag or on the inner side of the ring including the curve. In such a case, there is a surface or point heat fusion part in the heat fusion part of the line or ring, and the periphery of the surface or point heat fusion part is an air layer or a non-air layer. Become. By doing in this way, the reliability of heat sealing | fusion improves and the attachment property to a bag support frame becomes good.

  In the garbage container of the present invention, in order to improve the handling property at the time of disposal, a knot portion can be formed at both ends of the opening, and a part of the stopper may be positioned at the knot portion.

  By forming a part of the stopper in the knot portion in this way, the portion folded back by the bag support frame can be shortened, so that the entire length of the bag is shortened with the waste input capacity unchanged. be able to.

  The garbage container of the present invention is easy to attach the bag to the bag supporting means, and the attachment strength of the bag is improved.
