Abstract
Description
[Technical Field]
[0001] The present invention relates to containers, and in particular to toothpaste cases. [Background technology]
[0002] Oral hygiene has a significant impact on human health. If the oral cavity is not clean, bacteria can easily grow and enter the human body, causing infection and disease. Therefore, people have always attached great importance to oral hygiene. Currently, cleaning products for cleaning the oral cavity include, for example, toothpaste, tooth powder, mouthwash, etc. Among them, toothpaste is a widely used cleaning product, and toothpaste also has good cleaning effect, and is convenient to carry and refill, so it is very popular.
[0003] However, when using toothpaste to clean the mouth, it is generally necessary to wet the toothbrush and then place it directly into the toothpaste holder to extract the toothpaste. Therefore, the toothpaste in the toothpaste case is prone to hardening due to moisture and is prone to becoming contaminated, so that a large amount of toothpaste needs to be discarded and replaced overall. Furthermore, the contaminated toothpaste cases must be disposed of, resulting in waste of resources and increased usage costs.
[0004] Therefore, in order to solve these problems, it is necessary to provide a toothpaste case that is novel and innovative. Summary of the Invention [Problem to be solved by the invention]
[0005] To provide a toothpaste case that can easily dispense toothpaste, can keep the toothpaste in a position where it is easy to take out, and prevents the toothpaste from hardening and becoming contaminated. [Means for solving the problem]
[0006] In order to achieve the above object, the present invention provides a toothpaste case including: a storage body including an opening; an inner lid that covers the opening and includes a groove, the groove including a groove bottom wall and a peripheral wall connected to the groove bottom wall, the height of the peripheral wall relative to the groove bottom wall varying in the circumferential direction, the groove bottom wall being provided with a protrusion, and the protrusion being provided with a through-hole; and an outer lid that covers the storage body. [Brief explanation of the drawings]

[Figure 3] 1 is a schematic diagram showing a toothpaste case according to an embodiment of the present invention in an open state; [Figure 4] 1 is a perspective view of an inner lid of a toothpaste case according to an embodiment of the present invention.

[Figure 6] 1 is a plan view of an inner lid of a toothpaste case according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0008] Hereinafter, embodiments of the present invention will be described with reference to examples, but the present invention is not limited to these embodiments.
[0009] An embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG. The toothpaste case 1 of the present invention includes a container body 10 , an inner lid 20 and an outer lid 30 .
[0010] The housing body 10 includes an opening 11 . The inner cover 20 covers the opening 11 and includes a recess 21 . The groove 21 includes a groove bottom wall 211 and a peripheral wall 212 connected to the groove bottom wall 211 . The height of the peripheral wall 212 relative to the groove bottom wall 211 varies in the circumferential direction. The groove bottom wall 211 is provided with a protrusion 213, and the protrusion 213 is provided with a through hole 214. The outer cover 30 is placed over the container body 10 . This allows the toothpaste in the container body 10 to be guided through the through-hole 214 into the groove 21 in an appropriate amount, making it easier to use. The protrusion 213 keeps the toothpaste positioned in the groove 21 and prevents it from dropping into the container body 10 through the through hole 214, so that the toothpaste in the container body 10 is less likely to harden and is not contaminated.
[0011] In this embodiment, the containing body 10 includes a housing 12 and a container 13 contained in the housing 12 . The housing body 10 may be integrally formed, or may include only the container 13 . The container 13 includes an end tube portion 131 , which includes the opening 11 . The outer circumferential surface of the end tube portion 131 is provided with a plurality of locking grooves 132 spaced apart in the circumferential direction. The inner surface of the outer lid 30 is provided with a plurality of locking ribs 31 spaced apart in the circumferential direction. The plurality of locking ribs 31 are releasably inserted into the plurality of locking grooves 132 and locked thereto. This allows the outer lid 30 and the housing body 10 to be quickly locked or released.
[0012] More specifically, the outer peripheral surface of the end tube portion 131 is provided with a plurality of long ribs 133 spaced apart in the circumferential direction and a plurality of short ribs 134 spaced apart in the circumferential direction. The plurality of long ribs 133 and the plurality of short ribs 134 respectively define the plurality of locking grooves 132 . The long ribs 133 are preferably located above the short ribs 134, respectively, to provide a large engagement range and bonding strength for the engagement ribs 31. Preferably, guide angles 135 are provided at opposite ends of each of the long ribs 133 and the short ribs 134 to guide the locking ribs into the locking grooves 132 .
[0013] In this embodiment, the height of the peripheral wall 212 of the inner lid 20 changes smoothly and continuously in the circumferential direction. For example, the height of the peripheral wall 212 of the inner lid 20 gradually decreases in the direction approaching the through-hole 214 . Specifically, the protrusion 213 is connected to the peripheral wall 212 of the inner lid 20, providing good structural strength. The protrusion 213 has a tapered shape, and can guide the toothpaste in the container body 10 so that it can be smoothly led from the through hole 214 to the recess 21 . Preferably, the tip of the peripheral wall 212 of the inner lid 20 is a flange 215 extending radially outward. The flange 215 is connected to the container body 10 and overlaps the opening 11, so as to completely block the opening 11 and to stably and accurately position the inner cover 20. Preferably, the inner lid 20 further includes a pull tab 22 that a user can pull to lift the inner lid 20 for easy refilling, cleaning or replacement of toothpaste. The distance between the pull tab 22 and the protrusion 213 is equal to or less than the radial dimension of the protrusion 213 .
[0014] The flange 215 defines a horizontal reference line L. Preferably, the groove bottom wall 211 gradually approaches the horizontal reference line L in the direction of the convex portion 213 . That is, since the protrusion 213 is located in a relatively shallow portion of the groove 21 and the through hole 214 is located at a relatively high horizontal position, the toothpaste guided from the through hole 214 into the groove 21 automatically slides to a relatively deep portion of the groove 21 that is far from the through hole 214, ensuring that the toothpaste does not easily fall into the container body 10 through the through hole 214. This also helps to measure and control the amount of toothpaste dispensed each time. [Explanation of symbols]
