Description

  The present invention relates to a pet excreta disposal bag.

  Conventionally, excrement such as pet feces is handled outdoors by the owner in a processing bag. Such a waste disposal bag is usually brought with a plastic bag, folded inside and outside the plastic bag, put a hand inside the folded bag, grabbed the waste together with the bag, folded inside and outside again, Processing is done in the procedure of taking it in a bag and taking it home.

By the way, in the case of a small amount of excrement, the strength of the plastic bag does not matter, but in the case of a large pet such as a large dog, it is necessary to hold a large amount of excrement with a plastic bag and store it. As a result, cracks occur in the bottom welded part of the plastic bag when grasping or after storage, and there is a possibility that liquid leakage or breakage may occur in some cases.
Therefore, as a plastic bag for storing such pet excrement of weight, gussets are formed on both side edges so that the bottom gusset portion is constituted by thermal welding of four sheets, A bag has been developed that can withstand the weight burden of the body and that facilitates excrement accommodation work by expanding and contracting the gusset portion when grasping the excrement (see Patent Document 1).

[Example]
An embodiment of the present invention will be described in detail with reference to the drawings. Fig.1 (a) is a top view which shows the excrement disposal bag of a pet, FIG.1 (b) is AA sectional drawing of Fig.1 (a), FIG.1 (c) is FIG. It is XX sectional drawing of (a). The perspective view which shows the use condition which turned the inside and outside of the excrement disposal bag of a pet upside down.

  As shown in FIG. 1, the pet excrement disposal bag K is provided with a heat-welded portion T1 that is heat-welded at a location that becomes the bottom 9 of the bag, and is cut into a U shape in the vertical direction to hold the left and right bags. Portions H and H are formed. A lower end opening portion 12 is formed below the heat welding portion T1.

  The pet excrement disposal bag K is formed by forming a film cylinder on the flat cylinder 2 in which the front and back sheets 3 and 4 are flattened and folding the left and right edges 2a and 2a of the flat cylinder 2 inward and left and right. The gussets 5 and 6 are formed, and the leading edges 5a and 6a of the left and right gussets 5 and 6 are folded and formed so as to be superposed while maintaining a certain width.

  The pet excrement disposal bag K is provided with such folded left and right gussets 5 and 6 so that when used as a bag, the left and right gussets 5 and 6 are expanded to form a “town” in the thickness direction of the bag. In addition, the internal capacity can be expanded and the bag width is narrowed to achieve compactness.

  Furthermore, the portions corresponding to the bag opening 8 and the bottom 9 of the flat cylindrical body 2 integrally heat-bond the polymerized front and back sheets 3 and 4 and the polymerized polymer gusset 7 to form a multiple heat-welded portion T1 ′. The heat-welded portions T2 and T2 of the bag opening 8 are cut in a U-shape in the vertical direction including the gussets 5 and 6. That is, the end portion of each bag gripping portion H is heat welded to the front and back sheets 3 and 4 and the gussets 5 and 6, and the insertion holes 11 (see FIG. 3) are formed by forming the heat welded portions T2 and T2. Is formed. The polymerization gusset 7 has a configuration in which four sheets comprising two sheets constituting the gusset 5 and two sheets constituting the gusset 6 are polymerized, and the front and back sheets 3 and 4 are polymerized. A multiple heat welding portion T1 ′ composed of six film sheets is formed.

  In this way, the superposed front and back sheets 3 and 4 and the polymerized gusset 7 are integrally heat welded at the portion corresponding to the bottom portion 9 of the bag, so that the liquid does not easily leak and the strength of the bottom heat welded portion T1 is improved. Since the gussets 5 and 6 of the bottom 9 are polymerized and welded together, the strength of the portion where a large amount of excrement is subjected to a weight load can be increased. In other words, the front sheet 3, the polymerization gusset 7 and the back sheet 4 in the bottom heat-welded portion T1 overlap each other, and six sheets are superposed and welded.

  Further, as shown in FIG. 2 and FIG. 3, the single bag K formed by the bag opening 8 and the bottom 9 is separated from the palm of the palm to be inserted into the bag when the bag is folded inside and outside. F1 and the other four fingers F2, F3, F4, and F5 are located on the front sheet 3 side and the back sheet 4 side that are folded back with the multiple heat welded portion T1 ′ as the boundary, and the palm center part is a heat welded polymer gusset 7 is configured so that the raised portion of the excrement D when grasping the excrement D can be grasped while being wrapped with the palm located in the multiple heat weld T1 ′. doing.

  That is, at this time, the central portion of the bottom portion 9 of the bag is a multiple heat-welded portion T1 ′ of the polymerized front and back sheets 3 and 4 and the polymerized gusset 7, so that there is a thickness obtained by polymerizing six film sheets, and it is difficult for liquid to leak. The strength of the heat-welded portion T1 ′ is also improved, and particularly the strength of the portion where a large amount of excrement D is subjected to a weight load can be increased because of the polymerization welding between the gussets 5 and 6.

  Further, when the plastic bag K is folded back inside and outside again after holding the excrement D once inside and outside by folding the inside and outside, and the excrement D is accommodated in the bag, as shown in FIG. Since the excrement D is grasped by both sides of the bag other than the central multiple heat welding portion T1 ′ by the thumb F1 and the four fingers F2, F3, F4, F5 in the folded state, the inside and outside of the bag can be easily and again It can be folded back to the original. In this way, after the excrement D is accommodated in the plastic bag, it can be carried and transported with the grip portions H, H formed at the U-shaped notch of the opening 8 as a boundary.

  Furthermore, as shown to FIG.1 and FIG.4 (a), it was set as the structure which affixes the string tape S which obstruct | occludes the bag opening part 8 to the front sheet | seat 3 of the pet excrement disposal bag K. FIG.

  The string tape S is provided at a position deviating from the central portion in the width direction of the pet excrement disposal bag K, that is, a position deviating from the multiple heat welding portion T1 '. In this embodiment, as shown to Fig.1 (a), the string tape S is about the width direction of the pet excrement disposal bag K in the part of the holding part H (the right side in Fig.1 (a)). The pet excrement disposal bag K is affixed to the entire length in the longitudinal direction of the bag. With such a configuration, with respect to the thickness of the pet excrement disposal bag K, the thickness of the central portion in the width direction where the multiple heat-welded portion T1 ′ in which six film sheets are superposed is prevented from being locally thickened. can do. As a result, in the state where a plurality of pet excrement disposal bags K are stacked or wound in a roll shape in a state of being connected in a plurality, the thickness of the stack and the diameter of the roll shape are locally large. Therefore, it is possible to improve display properties and storage properties in a state where a plurality of pet excrement disposal bags K are packaged.

  When closing the bag opening 8, first, as shown in FIG. 4 (b), the string tape S is peeled off from the front sheet 3 from the front sheet 3 and the pet excrement D is stored, and then the bag opening 8. Can be closed with a string tape S (see FIG. 4C).

  Although the string tape S is attached to the front sheet 3, it may be attached to the back sheet 4 instead of the front sheet 3.

  Further, as shown in FIG. 5, the tape intermediate portion S <b> 1 of the string tape S is fixed to the front sheet 3. That is, by fixing the tape intermediate portion S1 of the string tape S in the vicinity of the bag opening 8, the tape tape S is wound around the fixed tape intermediate portion S1 as shown in FIG. 5B. This makes it easier to close the bag opening 8 (see FIG. 5C).
